Produced water that is piped from these producing wells to the Circle B Land #4 facility will be unloaded into the initial tank battery located on the southeast corner of the Circle B Land #4. Residual oil, approximately 0 to 1.5% of the fluid stream, will be allowed to separate by gravity and then removed from the water via this initial closed -tank gravity separation system. The water will then be pumped to a secondary tank battery to further remove residual oil from the produced water. Trucked produced water can also be unloaded at this point into the secondary tank battery. These proposed tank batteries provide settling time to allow the oil to break out by letting the oil rise to the top of the skim tanks and forced into 6" oil equalizer lines located at the top of the skim tanks which then flow into designated oil storage tanks. The oil stored in these tanks will then be sold just as it is at typical production sites. From this point the water will be piped into the water tank storage facility located to the far west of the proposed pad. As these storage tanks get full, the water will then be injected into the proposed onsite salt water disposal well, pumped offsite via pipeline to other disposal facilities or pumped offsite via pipeline to be used as makeup water for completion operations on newly drilled wells. The injection facilities will consist of an approx. 16' x 70' x 10' high building to house the proposed pumps. An electrical skid building, approximately 14' x 20' X 10' high will house the pump controls and electrical components necessary to operate the pumps. Combustors will be connected to the tank system to destroy hydrocarbon emissions and meet the appropriate air emission standards. No additional facilities or equipment are anticipated at this location at this time. GARFIELD COUNTY BUILDING AND PLANNING DEPARTMENT FEE SCHEDULE Garfield County, pursuant to Board of County Commissioners ("Board") Resolution No. 98-09, has established a fee structure ("Base Fee") for the processing of each type of subdivision and land use applications. The Base Fee is an estimate of the average number of hours of staff time devoted to an application, multiplied by an hourly rate for the personnel involved. The Board recognized that the subdivision and land use application processing time will vary and that an applicant should pay for the total cost of the review which may require additional billing. Hourly rates based on the hourly salary, and fringe benefits costs of the respective positions combined with an hourly overhead cost for the office will be used to establish the actual cost of County staff time devoted to the review of a particular project. Actual staff time spent will be charged against the Base Fee. After the Base Fee has been expended, the applicant will be billed based on actual staff hours accrued. Any billing shall be paid in full prior to final consideration of any land use permit, zoning amendment or subdivision plan. If an applicant has previously failed to pay application fees as required, no new or additional applications will be accepted for processing until the outstanding fees are paid. Checks, including the appropriate Base Fee set forth below, must be submitted with each land use application, and made payable to the Garfield County Treasurer. Applications will not be accepted without the required application fee. Base Fees are non-refundable in full, unless a written request for withdraw from the applicant is submitted prior the initial review of the application materials. Applications must include a Payment Agreement Form ("Agreement") set forth below. The Agreement establishes the applicant as being responsible for payment of all costs associated with processing the application. The Agreement must be signed by the party responsible for payment and submitted with the application in order for it to be accepted. The following Base Fees shall be received by the County at the time of submittal of any procedural application to which such fees relate. Such Base Fees shall be in addition to and exclusive of any cost for publication or cost of consulting service determined necessary by the Board for the consideration of any application or additional County staff time or expense not covered by the Base Fee, which have not otherwise been paid by the applicant to the County prior to final action upon the application tendered to the County.

Please contact me at (303) 312-8191 if you have any questions. Sincerely, Scot A. Donato Manager, EH&S Circle B Land Company Bill Barrett Corporation 1099 18TH STREET SUITE 2300 DENVER, CO 80202 P 303.293.9100 F 303.291.0420 PROJECT NARRATIVE As detailed in this application, the Circle B #4 Water Storage Facility will facilitate the collection, storage, and transfer of drilling water, completion flowback water, and produced water from BBC's natural gas wells. The facility will recycle water for reuse in BBC operations in the area. The facility will be located adjacent to the existing Circle B #4 well pad and will be built by expanding the existing pad to the west. The Circle B #4 Water Storage Facility is located south of the town of Silt in the northwest quarter of the southeast quarter of Section 35, Township 6 south, Range 92 west, in Garfield County, Colorado. The facility will basically consist of an offloading area, a primary settling tank battery, a secondary settling tank battery, a final water storage tank battery, and a salt water disposal well. Additional facilities will consist of pump building to house the proposed pumps, an electrical skid building for the pump controls and electrical components, and a piping valve control set. Further details and facility diagrams are provided in this application. The subject location is contiguous with an existing producing natural gas wellsite that contains wellheads and standard production equipment that is not associated with the proposed water storage facility. The proposed operation of this facility will allow BBC to gather water from its wellsites in the area, mainly by existing pipelines. Water that is piped from wells to the Circle B Land #4 facility will be unloaded into the initial tank battery located on the southeast corner of the Circle B Land #4 site. Residual oil, approximately 0 to 1.5% of the fluid stream, will be allowed to separate by gravity and then removed from the water via this initial closed -tank gravity separation system. The water will then be pumped to a secondary tank battery to further remove residual oil from the produced water. Trucked produced water can also be unloaded at this point directly into the secondary tank battery. The proposed tank batteries provide settling time to allow the oil to break out allowing the oil rise to the top of the skim tanks where the oil is then directed into 6" oil equalizer lines located at the top of the skim tanks that flow into designated oil storage tanks. The oil stored in these tanks will then be sold just as it is from typical production sites. After residual oil removal, the water will be piped into the water tank storage facility located to the far west of the proposed pad. Recycled water will be transported to other BBC area sites via pipeline or trucks, as available, to be used for drilling, completions, or other appropriate uses. , Any water that cannot be reused in the area will then be injected into the proposed onsite salt water disposal well that will be properly permitted with the Colorado Oil & Gas Conservation Commission (COGCC), or taken to other appropriate disposal facilities. The tank system will be a closed system utilizing one or more enclosed -flame combustors, similar to those used on producing wellsites, to collect and destroy hydrocarbon emissions. The combustor destruction efficiency will meet or exceed the appropriate Colorado Department of Public Health and Environment (CDPHE) requirement for air -emission health standards. STANDARDS CORDILLERAN A division of Olsson Associates OOLSSON ASSOCIATES Applicable Standards Article VII, Division 1, General Approval Standards for Land Use Change Permits Article VII, § 7-101 Compliance with Zone District Use Restrictions: A Water Tank and Treatment Facility is an allowed use within the Rural Land Zone District. Article VII, § 7-102 Compliance with Comprehensive Plan and Intergovernmental Agreements: The project location is identified on the Proposed Land Use Districts Map as "Outlying Residential". Although the proposed use is not residential in nature, it does not prohibit or adversely impact a residential use on the subject property. Garfield County Comprehensive Plan of 2000, 4.0 Commercial & Industrial Uses, states that the County will encourage the development of a diversified industrial base for the County which recognizes environmental and social impacts of industrial uses. Utilizing the proposed facility for storing water and re -using it in BBC's operations will significantly reduce the amount of potential truck traffic,, and associated noise, and dust from transporting water. In addition, this facility will eliminate the need for select water storage pits, thus conserving valuable land. The facility will recycle water for reuse thus preserving valuable fresh water resources. It will also improve the view -shed from neighboring lands, help preserve wildlife habitat in the area, and avoid or minimize potential impacts to neighboring properties and the environment. Construction and operation of this facility will result in a substantial improvement in operational efficiency and a significant reduction of surface facilities in the area relative to BBC's development of natural gas resources in the area. This use generally conforms to the Garfield County Comprehensive Plan. Article VII, § 7-103 Compatibility: The water storage facility is consistent with the current uses on the subject parcel and adjacent properties. The limited impacts of this facility are compatible with uses in the surrounding area. (See Impact Analysis 4-502 B. 1.) Circle B #4 Water Storage Facility 1 January 30, 2009 Standards Article VII, § 7-104 Sufficient Legal and Physical Source of Water: The water stored at this facility is water that has been produced by natural-gas wells operated by BBC; therefore no source of fresh water is required for this project. (See Land Suitability Analysis 4-502 D. 7. — Impact Analysis 4-502 E. 6. and 7.) Article VII, § 7-105 Adequate Water Supply: As indicated above, all water stored at this facility is drilling water, completion flowback water, and produced water from BBC's natural gas wells; therefore, no water supply plan is required. (See Land Suitability Analysis 4-502 D. 7. — Impact Analysis 4-502 E. 6. and 7.) Article VII, § 7-108 Access and Roadways: New roads are not proposed to accommodate the water storage facility. The facility will utilize the existing access previously authorized by Garfield County Road and Bridge Department. (See Land Suitability Analysis 4-502 D. 1. and 2.) Article VII, § 7-108 No Significant Risk from Natural Hazards: The project area is not at risk from natural hazards. (See Land Suitability Analysis 4-502 D. 10. — Impact Analysis 4-502 E. 5.) Article VII, Division 2, General Resource Protection Standards for Land Use Change Permits Article VII, § 7-201 Protection of Agricultural Lands: A. No Adverse Affect to Agricultural Operations - The construction and use of this water storage facility will not adversely affect agricultural operation on the subject property or adjacent lands. The facility has been designed to not impact the adjacent Multa-Trina ditch and multiple controls have been incorporated to reduce the possibility of spills and for secondary and tertiary containment in the unlikely event a spill should occur. The use of closed tanks will eliminate chances that livestock or wildlife could come into contact with the stored produced water. B. Domestic Animal Controls — The operation of the water storage facility will comply with this standard. C. Fences — The facility will be properly fenced and gated to prevent access by wildlife or livestock. Circle B #4 Water Storage Facility 2 January 30, 2009 Standards D. Roads — An existing road and access point will be utilized for the operation of the proposed use. One of the principal purposes for this water storage facility is to reduce traffic generated by BBC's operations in this area. E. Irrigation Ditches — Irrigation ditches on and adjacent to the subject property will not be impacted by the water storage facility. The facility was designed to minimize any potential impact to the Multa-Trina Ditch and other irrigation ditches in the vicinity. Article VII, § 7-202 Protection of Wildlife Habitat Areas: WestWater Engineering prepared a Wildlife and Sensitive Areas Report for the proposed use. The operation of the water storage facility is not anticipated to adversely impact Wildlife Habitat Areas. The report prepared by WestWater Engineering has been included in the Supplemental Information and is discussed in the Land Use Suitability and Impact Analyses. (See Impact Analysis 4-502 D. 8.; Land Use Suitability Analysis, 4-502 E. 11.) Article VII, § 7-203 Protection of Wetlands and Waterbodies: There are no wetlands or waterbodies in the vicinity of the proposed water storage facility. Article VII, § 7-204 Protection of Water Quality from Pollutants: The water storage facility is included in BBC's CDPHE construction field -wide stormwater management plan and permit.

The facility has been designed with secondary containment in the form of bermed and lined containment around the tank batteries, temporary diesel pumps, and associated fuel tanks, and tertiary containment along the north perimeter to further protect the Multa-Trina Ditch. The facility also will be covered by a Spill Prevention, Control and Countermeasures (SPCC) Plan that addresses measures that will be taken to prevent, control and respond to spills. Article VII, § 7-205 Erosion and Sedimentation: The water storage facility is included in BBC's CDPHE construction field -wide stormwater management plan and permit. During construction and operations, appropriate BMPs will be utilized to minimize stormwater runoff and thus erosion and sedimentation. Article VII, § 7-206 Drainage: The water storage facility has been designed so that all drainage will be controlled and there will be no adverse impact to adjacent property. Circle 13 #4 Water Storage Facility 3 January 30, 2009 Standards Article VII, § 7-207 Stormwater Runoff: The water storage facility is included in BBC's CDPHE construction field -wide stormwater management plan and permit. To reduce impacts during construction and operation, appropriate Best Management Practices (BMPs) will be utilized to protect surface waters from stormwater runoff. Article VII, § 7-208 Air Quality: This use will not adversely impact air quality. The tank system will be a closed system utilizing one or more enclosed -flame combustors, similar to those used on producing wellsites, to collect and destroy hydrocarbon emissions. The combustor destruction efficiency will meet or exceed the appropriate Colorado Department of Public Health and Environment (CDPHE) requirement for air -emission health standards. The tank system is designed to minimize emissions and also any potential odors. The facility will initially be equipped with two diesel pumps; however, these pumps may be replaced with electric pumps to further reduce emissions. Prior to operations commencing at this facility ail CDPHE air quality emission control, notice and permitting requirements will be satisfied. Article VII, § 7-209 Areas Subject to Wildfire Hazards: The project site is designated low to moderate wildfire hazard on the Garfield County Wildfire Hazard. (Impact Analysis Article IV, 4-502 E. 5. — Geology and Hazard) Article VII, § 7-210 Areas Subject to Natural Hazards and Geologic Hazards: The project site is not encumbered with any identified geologic or soil hazards. Article VII, § 7-211 Areas with Archeological, Paleontological or Historical Importance: Grand River Institute (GRI) conducted a Class I cultural resource survey for the proposed project and no sites have been previously recorded within the proposed project area. Two prehistoric archaeological sites (5GF304, and 5GF261) were identified and these are located well outside (>400 meters) of the proposed area of disturbance.

Land Suitability Analysis BILL BARRETT CORPORATION CIRCLE B #4 WATER STORAGE FACILITY Limited Impact Review Water Tank and Treatment Facility CORDILLERAN A division of Olsson Associates OA Project No. 008-2425 JANUARY 2009 OLSSON ASSOCIATES 826 21 1/2 Road 1 Grand Junction, CO 81505 1 970.263.7800 1 Fax 970.263.7456 Article IV, 4-502 D. 1. — Public Access: Access to the site is via Garfield County Road (CR) 331 (Dry Hollow Road) for approximately 5 miles south of the Town of Silt and then approximately 1.2 miles east on CR 326 (Chipperfield Lane) to a private access road (see Vicinity Map). The Circle B #4 Water Storage Facility location is approximately 0.5 mile south of CR 326 on this private access road. Truck traffic to the facility will follow haul routes designated by Garfield County. There is no historic public access through the proposed site. Article IV, 4-502 D. 2. — Access to Adjoining Roadways: The access point where the private access road intersects CR 326 is already permitted through the Garfield County Road & Bridge Department. As discussed in the traffic analysis provided in the Impact Analysis for this project, there are no site distance or intersection constraints that will result from this project. Article IV, 4-502 D. 3. — Easements: All existing easements and right-of-ways that could have an impact on or be impacted by this project are identified in the Site Plan section. However, this proposed project will not have any impact on or be impacted by the existing easements and right-of-ways. Aspen Valley Land Trust (AVLT) has a Conservation Easement covering 280 acres comprising the SWNW, N/2SW, SESW, SWNE AND W/2SE of Section 35, T6S-R92W. The subject water management facility is located upon approximately 6 acres out of this 280 -acre tract. This Conservation Easement was granted subsequent to BBC's oil and gas rights, so BBC's oil and gas rights are senior to this Conservation Easement. In an effort to minimize surface impact, BBC and AVLT have reached a mutual consensus as to the location of this facility. BBC/Circle B Land had originally planned to construct its water management facility at its Pad #6 location (SWSE Sec. 35), using a reserve/frac pit to store water needed for its oil and gas operations. However, AVLT and BBC/Circle B have agreed that it would be less potential impact upon the land, the wildlife migration habits and the view shed from neighboring lands to utilize steel storage tanks rather than a pit and to relocate this water management facility to BBC's Pad No. 4 (NWSE Sec. 35). Therefore, the pit at Pad #6 has now been drained, closed and is being reclaimed in accordance with COGCC reclamation requirements. The Impact Analysis discusses measures that will be implemented to help prevent impacts to the Multa-Trina ditch from this project. Circle B #4 Water Storage Facility 1 January 30, 2009 Land Suitability Analysis Article IV, 4-502 D. 4. — Topography and Slope: The average slope of the Circle B Land Pad #4 is approximately 1 %. This location is not within an area identified as a slope hazard by Garfield County. Article IV, 4-502 D. 5. — Natural Features: The Circle B Land #4 well pad is approximately 5 miles south of the town of Silt, Colorado. The pad is on a gentle slope at an elevation of 6,000 feet, in Zone 13S, Section 35, T6S, R92W. A detailed discussion of the natural features of this location is provided in the Integrated Vegetation and Noxious Weed Management Plan in Supplemental Information. The surrounding terrain is moderately hilly covered by pinon juniper woodland (favoring shallow soils), big sagebrush parks (favoring deeper soils), and pasture/hay land (favoring former sagebrush parks). An irrigation ditch flows north and west of the pad, running generally in an east/west direction. Bailey's ecoregional map shows the project in the Colorado Plateau's Shale Deserts and Sedimentary Basins Ecoregion. The soil is labeled a Potts Loam, which in a normal year produces approximately 800 pounds per acre of vegetal growth. The U.S. Natural Resources Conservation Service (NRCS) classifies the rangeland ecological site at the Circle B Well Pad #4 as a Rolling Loam (loamy soils on a rolling landscape). The area surrounding the well pad is dominated by hayland farming and livestock pasturage land with the associated irrigation and drainage ditches. No natural streams, reservoirs, or other significant water features are present in the vicinity of the well pad. Article IV, 4-502 D. 6. — Drainage Features: There are no significant drainages or impoundments in the vicinity of the Circle B Land #4 pad. Article IV, 4-502 D. 7. — Water: The Multa-Trina Ditch is located to the north of the Circle B Land # 4 pad (see Site Plan). There are other smaller irrigation and irrigation -return ditches located in the vicinity. The proposed project will not require a supply of water and, therefore, will not place any demands on local water sources. Article IV, 4-502 D. 8. — Floodplain: As indicated in Figure 1, the Circle B Land #4 pad is not located within a designated floodplain or flood fringe. Circle B #4 Water Storage Facility 2 January 30, 2009 Land Suitability Analysis Article IV, 4-502 D. 9. — Soils: A soils map for the location is provided in Figure 2. A soils report from the NRCS for the project area is provided in the Supplemental Information. The soil at the project location is the Potts Loam, 6 to 12 percent slopes. The Potts Loam is a deep well drained soil that formed in alluvium derived from sandstone, shale or basalt and range in thickness from 0 to 60 inches. Calcareous material is commonly found at depths of 9 to 18 inches. The properties of this soil indicate that it is compatible with the proposed use. Article IV, 4-502 D. 10. — Hazards: The surface geology of the facility is depicted on Figure 3. In general, the Circle B #4 location is underlain by the Tertiary Wasatch Formation. The Wasatch consists of interbedded and lenticular, varicolored gray, grayish yellow, yellowish- to reddish -brown, and reddish -purple claystone and siltstone, and gray and brown, fine- to coarse-grained sandstone and minor conglomerate. Although the Wasatch Formation does not appear to be prone to landsliding in the vicinity of the proposed facility under present climatic conditions, human activities that remove support (excavation), increase soil moisture, or add weight could trigger possible slope failure in the fine-grained strata of this unit (Colorado Geological Survey Publication OF -99-05, Hunter Mesa Quadrangle Geologic Map). In the immediate vicinity of the Circle B #4 location, the Wasatch Formation is overlain by younger, Quaternary -age alluvial deposits, principally sheetwash deposits (Figure 3; Colorado Geological Survey Publication OF -99-05, Hunter Mesa Quadrangle Geologic Map). The sheetwash deposits consist mainly of very pale -brown, pale -brown, brown, light -yellowish brown, and light -brown poorly sorted to extremely poorly sorted silty sand, fine sandy silt, clayey silt and sand, and minor amounts of pebble and cobble -size rock fragments. The sediment of this unit was transported and deposited principally by sheet flow. Most rock fragments are sandstone and were derived from the Wasatch Formation. In places, it also includes reworked as well as unmapped eolian sediment. In the vicinity of incised channels, the unit is subject to severe piping and subsequent collapse of the ground surface. This surface unit is between 3 and 40 ft thick. There are no geologic hazards identified on or adjacent to the site (Figure 4). Article IV, 4-502 D. 11. — Natural Habitat: WestWater Engineering conducted surveys of the project site for plant community conditions, listed noxious weeds and wildlife. The results of these surveys are provided in the Supplemental information and are summarized below. Circle B #4 Water Storage Facility 3 January 30, 2009 Land Suitability Analysis Big game species that frequent the project area include elk, mule deer, and black bears. Mule deer and elk severe winter range surrounds the well site. CDOW defines severe winter range to be where 90 percent of a species of wildlife are concentrated during the worst two winters in ten. Every winter both deer and elk concentrate in the general area. Black bears most commonly visit this area during the fall to fatten up for winter hibernation. Widely distributed game species (small game, furbearers) include rock squirrel, mountain cottontail, red fox, and coyote. Other non -game wildlife that characterize the area are Hopi chipmunk, Woodhouse toad, northern leopard frog, western terrestrial garter snake, and various commonly detected invertebrates, such as alfalfa and monarch butterflies. Other wildlife species known to be in the area include mourning doves, northern harrier, golden eagle, loggerhead shrike, pinon jay, Bewick's wren, black -throated gray warbler, and Brewer's sparrow. Several raptors reside or pass through the basin south of Silt. There are nesting records for red-tailed hawks, American kestrels, and long-eared owl. Strong evidence exists for great horned owls, Cooper's hawks, and northern saw -whet owls also nesting in the area. Swainson's and sharp -shinned hawks may nest in the area as well. Reports suggest that barn owls and western screech owls have expanded their ranges into the area almost certainly due to the recent stretch of mild winters. Northern pygmy owls, northern goshawks, rough -legged hawks, merlins, and bald eagles may winter in the basin. Four State -listed weed species are found near the Circle B Well Pad #4, two of which are listed by Garfield County (see Integrated Vegetation and Noxious Weed Management Plan in Supplemental Information). Colorado State -listed weeds observed on the proposed location are: Russian knapweed (Acroptilon repens), cheatgrass (Bromus tectorum), chicory (Cichorium intybus), and redstem filaree (Erodium cicutarium). Of these State -listed weeds, only Russian knapweed and chicory are listed by Garfield County. The locations of the listed weeds can be seen in the Integrated Vegetation and Noxious Weed Management Plan in Supplemental Information. Heaviest infestations of chicory and Russian knapweed were found north of the well pad along an irrigation ditch and in a field north of the irrigation ditch. Chicory was especially prolific along the irrigation ditch and more scattered in the field north of the irrigation ditch. Article IV, 4-502 D. 12. — Resource Areas: Grand River Institute (GRI) conducted a Class I cultural resource survey for the proposed project and no sites have been previously recorded within the proposed project area. Two prehistoric archaeological sites (5GF304, and 5GF261) were identified and these are located well outside (>400 meters) of the proposed area of disturbance. Additionally, five cultural resource projects have been conducted in the general vicinity. The proposed project is an Circle B #4 Water Storage Facility 4 January 30, 2009 Land Suitability Analysis expansion of an existing pad location and will occur primarily on land previously disturbed by well pad construction activities. GRI's report is provided in the Supplemental Information. Circle B #4 Water Storage Facility 5 January 30, 2009 Land Suitability Analysis IMPACT ANALYSIS Article IV 4-502 E.

The uses occurring on these properties are primarily agricultural, rural residential and natural gas development. The facility proposed by BBC has been designed to avoid and/or minimize the impact on these adjacent land uses and, in fact, the proposed facility will reduce the overall impact of BBC's operations on all adjacent landowners. The construction and operation of this facility will enable BBC to move water, primarily through pipelines, to and from its natural gas operations in the area with a minimum of truck traffic. In addition, when a salt water disposal well has been permitted by the COGCC and constructed on this location, the number of trucks that normally would be required to haul water to offsite disposal facilities will be further reduced . In response to concerns raised regarding a previous water storage pit operated by BBC at the Circle B Pad #6 location, BBC has closed and is reclaiming that facility, which will be replaced with this proposed storage facility. The former facility consisted of an open pit for storage of water which resulted in potential impacts to wildlife and adjacent landowners. The facility proposed for the Circle B #4 location was specifically located and designed to minimize such impacts. The location for the proposed facility is on the backside of a small ridge which will minimize its visual and noise impact. The facility has been designed to utilize a series of closed -top tanks instead of an open pit to mitigate possible impacts to wildlife, livestock, and the environment. All tank will be piped to a vapor combustion unit to significantly reduce air emissions and odors. The pumps planned for the facility will also be enclosed in buildings to reduce noise. The features of the facility's design and operation that will minimize impact on adjacent lands are discussed further in subsequent sections of this impact analysis. The nearest residence to the proposed facility is one owned by BBC/Circle B Land Company that is approximately 1,500 feet to the northwest (see Site Plan). The facility is located approximately 467 feet from the nearest property boundary (see Site Plan). Article IV, 4-502 E. 3. — Site Features: Significant features of the Circle B #4 site are described in the Land Suitability Analysis. As discussed in that analysis, there are no significant features that will be impacted by or have an impact on the proposed project. As discussed in more detail below, the proposed facility has been designed to minimize any potential impact to the Multa-Trina Ditch or other surface and ground water features from the operation of this facility. Circle B #4 Water Storage Facility 4 January 30, 2009 Impact Analysis Article IV, 4-502 E. 4. — Soil Characteristics: The soils of the site are described in the Land Suitability Analysis. The properties of the soil at the project location, the Potts Loam, indicate that the soil is compatible with the proposed use. As indicated in the discussion of the proposed reclamation plan, below, the top soil removed from the site during construction will be utilized for interim reclamation to ensure the continued viability of the top soil during the life of the facility. Article IV, 4-502 E. 5. — Geology and Hazard: The geology of the site and identified natural or man-made hazards are described in the Land Suitability Analysis. As indicated in that analysis, there are no geologic hazards identified in the vicinity of the proposed project and the geology of the site is not prone to landslides or other hazards. Some of the surficial sheetwash deposits at the site are noted as being prone to piping and collapse; however, these events only occur in areas where these deposits have been incised by channels. This is not the case at the location of the proposed facility, so such events are not likely. Article IV, 4-502 E. 6. — Effect on Existing Water Supply and Adequacy of Supply: The proposed project will store only water from BBC's natural gas well operations in the area, therefore, no supply of water is required an no demand will be placed on local water resources. Article IV, 4-502 E. 7. — Effect on Groundwater and Aquifer Recharge Areas: As discussed in the Land Suitability Analysis, there are no floodplains in the vicinity of the proposed facility. The facility has been designed to eliminate the potential of produced water or fuels impacting surface or ground waters. The tank batteries that will be used to store the water will have secondary containment consisting of a synthetic liner beneath the tanks and a steel containment structure around the tank battery and the liner will be carried up the side of the steel containment structure. In addition, an earthen berm will be constructed around the perimeter of the facility to further minimize the potential for spills to impact adjacent land and to control stormwater runoff (see Site Plan for details). The pumps and associated fuel tanks will also be provided with secondary containment structures to contain any potential leaks or spills. The facility will be covered under BBC's SPCC Plan for the East Mamm Creek Field and BBC's field -wide CDPHE construction stormwater management plan (both included in Supplemental Information). Particular attention has been paid to designing the facility to minimize the potential for impacts to the Multa-Trina Ditch. All of the tanks on this facility will be equipped with automatic fluid level sensors and automatic shutoffs. In addition, the secondary containment surrounding the Circle B #4 Water Storage Facility 5 January 30, 2009 Impact Analysis tank batteries will also be equipped with fluid level indicators and automatic shutoffs to stop the flow of water to the facility as necessary. Article IV, 4-502 E. 8. — Environmental Effects The existing environmental conditions are described in the Land Suitability Analysis and various reports contained in the Supplemental Information. Each of the factors that are required to be considered in this Impact Analysis is discussed below. Article IV, 4-502 E. 8. a. - Determination of the long term and short term effect on flora and fauna. The impacts to flora and fauna from this facility and measures that can be taken to mitigate those impacts are described in detail in the Integrated Vegetation and Noxious Weed Management Plan and Wildlife Assessment and Mitigation Report included in the Supplemental Information. BBC will implement the mitigation measures prescribed by these two documents. Article IV, 4-502 E. 8. b. - Determination of the effect on significant archaeological, cultural, paleontological, historic resources. As indicated in the Class 1 Class I cultural resource survey for the proposed project no sites have been previously recorded within the proposed project area. Two prehistoric archaeological sites (5GF304, and 5GF261) were identified and these are located well outside (>400 meters) of the proposed area of disturbance. Additionally, five cultural resource projects have been conducted in the general vicinity. The proposed project is an expansion of an existing pad location and will occur primarily on land previously disturbed by well pad construction activities. Article IV, 4-502 E. 8. c. - Determination of the effect on designated environmental resources, including critical wildlife habitat. The impacts to designated environmental resources from this facility and measures that can be taken to mitigate those impacts are described in detail in the Integrated Vegetation and Noxious Weed Management Plan and Wildlife Assessment and Mitigation Report included in the Supplemental Information. BBC will implement the mitigation measures prescribed by these two documents. Article IV, 4-502 E. 8. d. - Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. The impacts to wildlife from this facility and measures that can be taken to mitigate those impacts are described in detail in the Wildlife Assessment and Mitigation Report included in the Circle B #4 Water Storage Facility 6 January 30, 2009 Impact Analysis Supplemental Information. BBC will implement the mitigation measures prescribed by that plan. The facility is not expected to impact domestic animals or wildlife. Article IV, 4-502 E. 8. e. - Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments. There are no potential radiation hazards associated with this facility. Article IV, 4-502 E. 8. e. - Spill Prevention Control and Counter Measures plan, if applicable. . As indicated above, this facility will be covered by BBC's SPCC Plan for the East Mamm Creek Field and this plan is included in the Supplemental Information. Article IV, 4-502 E. 9. — Traffic A Basic Traffic Analysis, as required by §4-502J of the Garfield County Unified Zoning Resolution, is included in the Supplemental Information. As indicated in this analysis, the volume of traffic that will be generated from the construction and operation of this facility do not meet the thresholds that would trigger a Detailed Traffic Analysis. The Basic Traffic Analysis indicates that the existing access routes and points are adequate as currently constructed. Article IV, 4-502 E. 10. — Nuisance As discussed in detail above, the facility has been designed and will be operated in a manner that minimizes impact on adjacent land. The use of closed -top tanks that are piped to a vapor combustion system will virtually eliminate adverse odors from the facility. Prior to operations commencing at this facility all CDPHE air quality emission control, notice and permitting requirements will be satisfied. BBC will continue to implement its standard dust control practices to minimize dust that results from facility construction and vehicle traffic associated with the facility. This use will comply with Colorado Revised State Statute regarding noise at all times. After the installation of all equipment, a sound analysis will be conducted if deemed necessary by the Board of County Commissioners. No smoke, glare, vibration or other emanations would be expected from this facility. Article IV, 4-502 E. 11. — Reclamation Pian Reclamation of the proposed facility will occur in two distinct phases. Upon completion of construction of the facility, the cut and fill slopes on the exterior of the facility will be contoured to eliminate abrupt angular transitions and linear placement on visible slopes. Top soil removed during construction will be spread on these slopes and will be reseeded with the seed mix specified in the Integrated Vegetation and Noxious Weed Management Plan provided in the Supplemental Information.

Specifically, this addendum addresses the standards contained in §§7-801 and 7-821 of the Garfield County Unified Land Use Resolution. Article VII, 7-810 — Additional Standards Applicable to Industrial Use: A. No fabrication, service or repair operations will be conducted on this location. B. All operations involving loading and unloading of vehicles will be conducted on private property and will not be conducted on a public right-of-way. C. As documented in the Land Suitability Analysis, the location for this facility was specifically selected to conceal the facility from adjacent property. D. No industrial wastes are anticipated to be generated by this project, however, in the event that such wastes are generated, they will be disposed of in a manner consistent with statutes and requirements of CDPHE. E. The volume of sound generated will comply with the standards set forth in the Colorado Revised Statutes. If required by the BOCC, BBC will conduct a noise analysis of the facility after the facility is in operation to demonstrate compliance with these standards. F. This facility would not be anticipated to produce ground vibration perceptible without instruments at any point at any boundary line of the property. G. As documented in the Impact Analysis, this featured has been designed to minimize emissions of fumes which might substantially interfere with the existing use of adjoining property or which constitutes a public nuisance or hazard. The facility would not be anticipated to emit heat, glare, or radiation. Article VII, 7-811k— Additional Standards Applicable to Storage Areas and Facilities: A. Storage of Hazardous Materials. All hazardous materials associated with the construction and operation of this facility will be stored according to the manufacturer's standards and shall comply with the national, state and local fire codes and written recommendations from the appropriate local fire protection district. B. Materials and Wastes Contained on Property. As detailed in the Impact Analysis, several design features and operational practices will be employed to prevent material from leaving this property. As shown on the diagram contained in the Spill Prevention, Control and Countermeasures (SPCC) Plan included in the LIR application, the entire tank battery will be underlain with a synthetic liner and surrounded by a steel containment ring. This containment system provides for 16,520 barrels (bbl; 693,840 gallons) of containment in the event of a leak. Federal SPCC requirements generally only require that secondary containment be provided for the working capacity of the largest tank within the containment. In this event, the proposed containment is in excess of 25 times that required by SPCC regulations. In addition, the tank battery is designed so that each tank is equipped with a check valve that will prevent that tank from emptying in the event another tank in the battery leaks and the entire system will be monitored remotely so that leaks can be responded to promptly. An earthen berm will also be constructed along the northern perimeter of the location to provide additional protection to the Multa-Trina Ditch. C. Outdoor Storage Enclosed or Concealed. As documented in the Land Suitability Analysis, the location for this facility was specifically selected to conceal the facility from adjacent property. D. Use and Storage of Heavy Equipment. No heavy equipment will be stored at this location, and heavy equipment will only be used during construction or maintenance/repairs. 264-- o 41,e__ Article IV 4-502 E.

The noxious weed management program specified in the Integrated Vegetation and Noxious Weed Management Plan provided in the Supplemental Information will be implemented throughout the life of the facility. When this facility is no longer required to support BBC's natural gas operations the facility will undergo final reclamation within 6 months of the decommissioning of the facility. All buildings, tanks, and other equipment will be removed from the location. The top soil that was placed around the perimeter of the location during the initial construction of the facility will be stripped off for use in final reclamation. The location will then be regraded to return the location to as close to pre -disturbance conditions as possible and the top soil will be placed on all disturbed areas and reseeded with the seed mix specified in the Integrated Vegetation and Noxious Weed Management Plan provided in the Supplemental Information. Circle B #4 Water Storage Facility 8 January 30, 2009 Impact Analysis SUPPLEMENTAL INFORMATION Amendment to: Wildlife Assessment and Mitigation Report Circle B Well Site #6 (which was prepared for Bill Barrett Corporation in November 2007) WestWater Engineering (WWE) conducted a site inspection of Bill Barrett Corporation's (BBC) Circle B Well Site #6 (located in Zone 13S, Section 35, T6S, R92W, Figure 1) on September 24, 2007 and prepared a Wildlife Assessment and Mitigation Report (see attached). On December 11, 2008, WWE conducted another site inspection of BBC's Circle B Well Pad #4 (also located in Zone 13S, Section 35, T6S, R92W) at the request of Cordilleran Compliance Services, LLC to gather information for inclusion in another Wildlife Assessment and Mitigation Report. Due to the proximity of BBC's Circle B Well Pad #6 to Well Pad #4 (Figure 2), WWE has attached this amendment to the previously submitted Wildlife Assessment and Mitigation Report. The report prepared for the Circle B Well Pad #6 is entirely applicable for the #4 site and no additional analysis is needed. 111 l_� t - I Figure 1 BBC Amendment Circle B Well Number6 December 2008 'WestWater Engineering w....e..e.dre...lw W..

Wildlife WestWater Engineering Miles 0 0.05 0.1 0.2 Figure 3. Sagebrush "park" southwest of Circle B Well Pad #6, Garfield County, Colorado Several raptors reside or pass through the basin south of Silt. There are nesting records for red- tailed hawks, American kestrels, and long-eared owl. Strong evidence exists for great horned owls, Cooper's hawks, and northern saw -whet owls also nesting in the area. Swainson's and sharp -shinned hawks may nest in the area as well. Reports suggest that barn owls and western screech owls have expanded their ranges into the area almost certainly due to the recent stretch of mild winters. Northern pygmy owls, northern goshawks, rough -legged hawks, merlins, and bald eagles winter in the basin. Other Wildlife Widely distributed game species (small game, furbearers) include rock squirrel, mountain cottontail, red fox, and coyote. In addition to the birds mentioned above, other non -game wildlife that characterize the area are Hopi chipmunk (observed September 24 on edge of well pad), Woodhouse toad, northern leopard frog, western terrestrial garter snake, and various commonly detected invertebrates, such as alfalfa and monarch butterflies (Duff and Lawson 2004, Hammerson 1986, Opler and Wright 1999). The frog is a Colorado State Species of Special Concern. PLANNED WILDLIFE MEASURES AND RATIONALE The Circle 13 Well Pad #6 was built on PJ and sagebrush dominated ground. Returning it to original vegetative cover after site closure would take decades. It would depend upon natural vegetative community succession rather than a deliberate planting of PJ and sagebrush plants. If site expansion is ever contemplated, sensitivity should be greatest toward the sagebrush community and, if possible, expand into PJ or other types, giving deference to sagebrush. To minimize impacts to migratory birds during expansion, scheduling vegetation clearance outside the primary nesting season of May 15 to August 1 would benefit. WestWater Engineering Page 4 of 8 pages November 2007 Figure 4. Bill Barrett Corporation Circle B Well Pad 6, Garfield County, Colorado, showing that most heater -treater exhaust pipes have bird -excluding cones on top, yet one visible against the sky background, in the photo on the right, does not. Figure 5. The mountain bluebird is a frequent victim to asphyxiation due to perching at the top of heater -treater stacks that don't have prevention cones installed. The mountain bluebird pictured (top of pipe in foreground) is only on a pipe fence post. (Bill Barrett Corporation, Rodreick Well Pad, Garfield County, Colorado) Raptor electrocutions on power poles and resultant power outages can be avoided by using raptor protection guidelines produced by the Avian Power Line Interaction Committee (1996). If fences are to be erected (perhaps to keep livestock out of a reserve pit), to prevent entanglement, they should be designed to exclude deer or to provide the wire spacing recommended. Tall towers also can constitute wildlife hazards. If, or when, a tower over 200 feet high or any other potential hazard becomes a feature of the project, it should be designed with standard wildlife safe elements following consultation with specialists such as those at WWE. Some species of wildlife adapt to human presence and edifices well enough to become nuisances. If this occurs, it is usually best to contact CDOW for advice before taking on the task of removing the nuisance. WestWater Engineering Page 6 of 8 pages November 2007 Opler, P. A. and A.B.

Most have come from Europe or Asia, either accidentally or as ornamentals that have escaped. Once established in a new environment they tend to spread quickly because insects, diseases, and animals that normally control them are absent. Noxious weeds are spread by man, animals, water, and wind. Prime locations for the establishment of noxious weeds include roadsides, sites cleared for construction, areas that are overused by animals or humans, wetlands, and riparian corridors. Subsequent to soil disturbances, vegetation communities can be susceptible to infestations of invasive or exotic weed species. Vegetation removal and soil disturbance during construction can create optimal conditions for the establishment of invasive, non-native species. Construction equipment traveling from weed -infested areas into weed -free areas could disperse noxious or invasive weed seeds and propagates, resulting in the establishment of these weeds in previously weed -free areas. The Colorado Noxious Weed Act (State of Colorado 2005) requires local governing bodies to develop noxious weed management plans. Both the State of Colorado and Garfield County maintain a list of plants that are considered to be noxious weeds. The State of Colorado noxious weed list includes three categories. List A species must be eradicated whenever detected. List B species include weeds whose spread should be halted. List C species are widespread, but the State will assist local jurisdictions which choose to manage those weeds.

The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; • wetland vegetation, if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub -soil relative to the position from which the wetland sod was removed; • cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • in all cases, temporary disturbance should be kept to an absolute minimum; • equipment and materials handling should be done on established sites to reduce area and extent of soil compaction; • disturbances should be immediately reseeded with the recommended mix in the re - vegetation section; • topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses, if stored longer than one growing season; • prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • if working in sites with weed -seed contaminated soil, equipment should be cleaned of potentially seed -bearing soils and vegetative debris prior to moving to uncontaminated terrain. Weed Control Control methods for the Garfield County listed weed species found in the project area are described in Table 2.

Conner, Principal Investigator Grand River Institute P.O. Box 3543 Grand Junction, Colorado 81502 BLM Antiquities Permit No. C-52775 Submitted to Board of County Commissioners Garfield County, Colorado Abstract At the request of Bill Barrett Corporation, Grand River Institute (GRI) conducted a Class I cultural resource inventory for the proposed Circle B Land #33A-25-692/Circle B Land Pad #4 expansion project. The project area is located on private land in Garfield County, Colorado. This work was performed under BLM Permit No. C-52775. The Class I inventory was undertaken to ensure the project's compliance with state and federal legislation governing the identification and protection of cultural resources on federal lands that will be affected by a government action. The purpose of the cultural resources investigation was to identify previously recorded resources within or near the project area that may be adversely affected by the proposed action and to evaluate the potential of additional such resources in the project area. The Class I files search and report preparation were performed between the 16th and 20th of January 2009. As a result of the files search, no sites have been previously recorded within the proposed project area. Two prehistoric archaeological sites (5GF304, and 5GF261) were identified and these are located well outside (>400 meters) of the proposed area of disturbance. Additionally, five cultural resource projects have been conducted in the general vicinity. The proposed project is an expansion of an existing pad location and will occur primarily on land previously disturbed by well pad construction activities. Accordingly, no further work is recommended for the proposed project. ii TABLE OF CONTENTS Introduction 1 Location of the Project Area 1 Environment 1 Paleoclimate 4 Files Search Results 4 Discussion/Archaeological Assessment of Cultural Resources 6 Summary and Recommendations 7 References 7 LIST OF FIGURES AND TABLES Figure 1.

List of projects previously conducted near the study area 5 iii Introduction At the request of Bill Barrett Corporation, Grand River Institute (GRI) conducted a Class I cultural resource inventory for the proposed Circle B Land #33A-25-692 /Circle B Land Pad #4 expansion project. The project area is located on private land in Garfield County, Colorado. This work was performed under BLM Permit No. C-52775. The Class I files search and report preparation were performed Carl E. Conner, Principal Investigator, and Barbara Davenport between the 16th and 20th of January 2009. The Class I inventory was undertaken to ensure the project's compliance with state and federal legislation governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. It was done to meet requirements of the National Historic Preservation Act (as amended in 1992), the National Environmental Policy Act of 1969 (42 U.S.C. 4321), the Federal Land Policy and Management Act of 1976 (43 U.S.C. 1701), and the Archaeological Resources Protection Act of 1979 (16 U.S.C. 470aa et seq., as amended), and Article 80.1, Colorado Revised Statutes. These Iaws are concerned with the identification, evaluation, and protection of fragile, non-renewable evidence of human activity, occupation, and endeavor reflected in districts, sites, structures, artifacts, objects, ruins, works of art, architecture, and natural features that were of importance in human events. Such resources tend to be localized and highly sensitive to disturbance. All work was performed according to guidelines set forth by the Office of Archaeology and Historic Preservation (OAHP) of the Colorado Historical Society. Location of the Project Area The study area is located about 5 miles south of the town of Silt, in Garfield County, CO. The 10 -acre study block occurs in T. 6 S., R. 92 W., Section 35; 6'h P.M. (Figure 1). The area of previous well construction disturbance is shown in Figure 2. Environment The project area is located at the south margin of a large northwest -southeast trending structural downwarp known as the Piceance Basin. Subsidence of the Basin probably began some 70 million years ago, with the onset of the Laramide Orogeny during Late Cretaceous times, and continued until the Late Eocene (Young and Young 1977:46). During this period of roughly 25 million years, the Basin received as much as 9000 feet of Tertiary stream and lake deposits, all of which gently dip toward the center of the downwarp. Subsequent uplift and erosion along the Basin's margins have carved from the Basin sediments such topographic "highs" as the Roan Plateau, Grand Mesa, and Battlement Mesa (ibid.). The project area lies south of the Colorado River on a low mesa west of Divide Creek. 1 1 1 1 414 272000'+ar.«, kik I' Composite Quadrangle Maps Gibson Gulch and Hunter Mesa (1963119$7) Garfield County - Colorado U.S.O.S. 7.5' Saris (topographic) Scale 1:24000 Contour Interval 40 Feet T. 6 S., R. 92 W., 6th P.M.

Map showing previously disturbed area for the proposed Circle B Land #33A-35- 692/Circle B Land Pad #4 expansion project . 3 The region has a cool desert climate. Precipitation ranges between 10 and 14 inches, although the surrounding mountain areas may receive up to 20 inches. Temperatures range from about 95 degrees F in the summer to -5 degrees F during January. A frost -free period of about 150 days is the maximum (USDA SCS 1978b:403). Paleo-environmental data for the area are scant, but it is agreed that gross climatic conditions have remained fairly constant over the last 12,000 years. Still, changes in effective moisture and cooling) warming trends probably affected the prehistoric occupation of the area. Elevations of the project area average 5960 feet, which fall within the Upper Sonoran zone. Natural vegetation within and surrounding the previous disturbance for the proposed project consists primarily of pinyon/juniper forest, open sage flats, and cheatgrass. Ground visibility in the project area averages 60%. However, the actual proposed area of disturbance has been previously impacted by the construction of the existing well. Present land uses in the vicinity are open range, agricultural fields and energy development. Wildlife inhabitants including mule deer, elk, coyote, and black bear are common in the surrounding area, as are cottontail rabbits and various rodents. Mountain lion, bobcat, fox, skunk, badger, and weasel are also likely inhabitants. Bird species observed in the area include the jay, raven, red -shafted flicker, long-eared owl, golden and bald eagles and various other raptors. Paleoclimate Relatively small changes in past climatic conditions altered the exploitative potential of an area and put stress upon aboriginal cultures by requiring adjustments in their subsistence patterns. Therefore, reconstruction of paleoenvironmental conditions is essential to the understanding of population movement and cultural change in prehistoric times (Euler et al. 1979). To interpret whatever changes are seen in the archaeological record, an account of fluctuations in past climatic conditions must be available or inferences must be made from studies done in surrounding area. Generally, only gross climatic trends have been established for western North America prior to 2000 BP (Antevs 1955; Berry and Berry 1986; Mehringer 1967; Madsen 1982; Wendlund and Bryson 1974; Peterson 1981). Scientific data derived from investigations of prehistoric cultures and geoclimatic and bioclimatic conditions on the southern Colorado Plateau over the past two millennia have achieved a much greater degree of resolution (Dean et al. 1985). Files Search Results Cultural resource investigations in the region have yielded surface diagnostic artifacts and excavated cultural materials consistent with the regional cultural history. Evidence provided by chronometric diagnostic artifacts and radiocarbon analyses indicate 4 regional occupation during the Paleoindian Era, Archaic Era, Formative Era, and Protohistoric Era. Historic records suggest occupation or use of the region by EuroAmerican trappers, settlers, miners, and ranchers as well. Overviews of the prehistory and history of the region are provided in the Colorado Council of Professional Archaeologists' publications entitled "Colorado Prehistory: A Context for the Northem Colorado River Basin" (Reed and Metcalf 1999), and "Colorado History: A Context for Historical Archaeology" (Church et al. 2007). Files searches for known cultural resources within the project area were made through the Colorado Historical Society's Office of Archaeology and Historic Preservation. This review identified two previously recorded prehistoric sites (Table 1). These two sites occur over 400 meters away from the presently proposed project. Additionally, five cultural resource projects that have been conducted in the general vicinity (Table 2). Table 1. List of previously recorded resources in the near vicinity of the project area.

In that study, eight variables were found to be the most useful in the prediction of open air sites. These include site slope, aspect, horizontal distance to water (permanent and nearest), vertical distance to water (permanent and nearest), view angle (horizontal), distance to vantage overlook, nearby relief (100 m. and 150 m. radius), and shelter from wind (O'Neil 1993:207-208). Most importantly, the findings reflect the relatively high occurrence of sites along the main drainages on the northeast apron of Grand Mesa. There is a concentration of sites generally within about 0.25 mile of those drainages and most occur within the present day pinyon juniper, big sagebrush, desert shrub or saltbush communities. However, the key factor appears to be proximity to the water source. Most likely sites in the general vicinity were utilized during periods of migration between the mountainous regions of the Grand and Battlement Mesas and the White River Plateau, or migration between the higher elevations of the Mesas and the lower elevations along the Colorado River. 6 Summary and Recommendations As a result of the files search, no sites have been previously recorded within the proposed project area. Two prehistoric archaeological sites (5GF304, and 5GF261) were identified and these are located well outside (> 400 meters) of the proposed area of disturbance. Additionally, five cultural resource projects have been conducted in the general vicinity. The proposed project is located on an existing pad location and will occur on land disturbed by well pad construction and reclamation activities. Accordingly, no further work is recommended for the proposed project. References Antevs, E. 1955 Geologic -climate dating in the west. American Antiquity 20:317-355. Berry, Michael S. and Claudia F.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://soils.usda.gov/sgil) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app? agency=nrcs) or your NRCS State Soil Scientist (http://soils.usda.gov/contact/ state_officesl). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is ajoint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Soil Data Mart Web site or the NRCS Web Soil Survey. The Soil Data Mart is the data storage site for the official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, Iandforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil - landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 6 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. 10 Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 11 Custom Soil Resource Report Rifle Area, Colorado, Parts of Garfield and Mesa Counties 56—Potts loam, 6 to 12 percent slopes Map Unit Setting Elevation: 5,000 to 7,000 feet Map Unit Composition Potts and similar soils: 85 percent Description of Potts Setting Landform: Valley sides, benches, mesas Down-slope shape: Convex, linear Across -slope shape: Convex, linear Parent material: Alluvium derived from basalt and/or alluvium derived from sandstone and shale Properties and qualities Slope: 6 to 12 percent Depth to restrictive feature: More than 80 inches Drainage class: Well drained Capacity of the most limiting layer to transmit water (Ksaf): Moderately high (0.20 to 0.60 in/hr) Depth to water table: More than 80 inches Frequency of flooding: None Frequency of ponding: None Calcium carbonate, maximum content: 15 percent Maximum salinity: Nonsallne (0.0 to 2.0 mmhoslcm) Available water capacity: High (about 10.3 inches) Interpretive groups Land capability classification (irrigated): 4e Land capability (nonirrigated): 4e Ecological site: Rolling Loam (R048AY298C0) Typical profile 0 to 4 inches: Loam 4 to 28 inches: Clay loam 28 to 60 inches: Loam 12 References American Association of State Highway and Transportation Officials (AASHTO). 2004.

ABC soil A soil having an A, a 13, and a C horizon. Ablation till Loose, relatively permeable earthy material deposited during the downwasting of nearly static glacial ice, either contained within or accumulated on the surface of the glacier. AC soil A soil having only an A and a C horizon. Commonly, such soil formed in recent alluvium or on steep, rocky slopes. Aeration, soil The exchange of air in soil with air from the atmosphere. The air in a well aerated soil is similar to that in the atmosphere; the air in a poorly aerated soil is considerably higher in carbon dioxide and lower in oxygen. Aggregate, soil Many fine particles held in a single mass or cluster. Natural soil aggregates, such as granules, blocks, or prisms, are called peds.

Brush management increases forage production and thus reduces the hazard of erosion. It can improve the habitat for some species of wildlife. Butte An isolated, generally flat-topped hill or mountain with relatively steep slopes and talus or precipitous cliffs and characterized by summit width that is less than the height of bounding escarpments; commonly topped by a caprock of resistant material and representing an erosion remnant carved from flat -lying rocks. Cable yarding A method of moving felled trees to a nearby central area for transport to a processing facility. Most cable yarding systems involve use of a drum, a pole, and wire cables in an arrangement similar to that of a rod and reel used for fishing. To reduce friction and soil disturbance, felled trees generally are reeled in while one end is lifted or the entire log is suspended. Calcareous soil A soil containing enough calcium carbonate (commonly combined with magnesium carbonate) to effervesce visibly when treated with cold, dilute hydrochloric acid. Caliche A general term for a prominent zone of secondary carbonate accumulation in surficial materials in warm, subhumid to arid areas. Caliche is formed by both geologic and pedologic processes. Finely crystalline calcium carbonate forms a nearly continuous surface -coating and void -filling medium in geologic (parent) materials.

Conglomerate is the consolidated equivalent of gravel. Conservation cropping system Growing crops in combination with needed cultural and management practices. in a good conservation cropping system, the soil -improving crops and practices more than offset the effects of the soil -depleting crops and practices. Cropping systems are needed on all tilled soils. Soil -improving practices in a conservation cropping system include the use of rotations that contain grasses and legumes and the return of crop residue to the sail. Other practices include the use of green manure crops of grasses and legumes, proper tillage, adequate fertilization, and weed and pest control. Conservation tillage A tillage system that does not invert the soil and that leaves a protective amount of crop residue on the surface throughout the year.

It is typically coarser than the underlying material. Cuesta An asymmetric ridge capped by resistant rock layers of slight or moderate dip (commonly less than 15 percent slopes); a type of homocline produced by differential erosion of interbedded resistant and weak rocks. A cuesta has a long, gentle slope on one side (dip slope) that roughly parallels the inclined beds; on the other side, it has a relatively short and steep or clifflike slope (scarp) that cuts through the tilted rocks. Culmination of the mean annual increment (CMAI) The average annual increase per acre in the volume of a stand. Computed by dividing the total volume of the stand by its age. As the stand increases in age, 23 Custom Soil Resource Report the mean annual increment continues to increase until mortality begins to reduce the rate of increase. The point where the stand reaches its maximum annual rate of growth is called the culmination of the mean annual increment. Cutbanks cave The walls of excavations tend to cave in or slough. Decreasers The most heavily grazed climax range plants. Because they are the most palatable, they are the first to be destroyed by overgrazing. Deferred grazing Postponing grazing or resting grazing land for a prescribed period. Delta A body of alluvium having a surface that is fan shaped and nearly flat; deposited at or near the mouth of a river or stream where it enters a body of relatively quiet water, generally a sea or lake. Dense layer A very firm, massive layer that has a bulk density of more than 1.8 grams per cubic centimeter. Such a layer affects the ease of digging and can affect filling and compacting. Depression, closed (map symbol) A shallow, saucer-shaped area that is slightly lower on the landscape than the surrounding area and that does not have a natural outlet for surface drainage. Depth, soil Generally, the thickness of the soil over bedrock. Very deep soils are more than 60 inches deep over bedrock; deep soils, 40 to 60 inches; moderately deep, 20 to 40 inches; shallow, 10 to 20 inches; and very shallow, less than 10 inches. Desert pavement A natural, residual concentration or layer of wind -polished, closely packed gravel, boulders, and other rock fragments mantling a desert surface.

It typically protects the finer grained underlying material from further erosion. Diatomaceous earth A geologic deposit of fine, grayish siliceous material composed chiefly or entirely of the remains of diatoms. Dip slope A slope of the land surface, roughly determined by and approximately conforming to the dip of the underlying bedrock. 24 Custom Soil Resource Report Diversion (or diversion terrace) A ridge of earth, generally a terrace, built to protect downslope areas by diverting runoff from its natural course. Divided -slope farming A form of field striperopping in which crops are grown in a systematic arrangement of two strips, or bands, across the slope to reduce the hazard of water erosion. One strip is in a close -growing crop that provides protection from erosion, and the other strip is in a crop that provides less protection from erosion. This practice is used where slopes are not long enough to permit a full striperopping pattern to be used. Drainage class (natural) Refers to the frequency and duration of wet periods under conditions similar to those under which the soil formed. Alterations of the water regime by human activities, either through drainage or irrigation, are not a consideration unless they have significantly changed the morphology of the soil. Seven classes of natural soil drainage are recognized—excessively drained, somewhat excessively drained, well drained, moderately well drained, somewhat poorly drained, poorly drained, and very poorly drained. These classes are defined in the "Soil Survey Manual." Drainage, surface Runoff, or surface flow of water, from an area. Drainageway A general term for a course or channel along which water moves in draining an area. A term restricted to relatively small, linear depressions that at some time move concentrated water and either do not have a defined channel or have only a small defined channel. Draw A small stream valley that generally is shallower and more open than a ravine or gulch and that has a broader bottom. The present stream channel may appear inadequate to have cut the drainageway that it occupies. Drift A general term applied to all mineral material (clay, silt, sand, gravel, and boulders) transported by a glacier and deposited directly by or from the ice or transported by running water emanating from a glacier. Drift includes unstratified material (till) that forms moraines and stratified deposits that form outwash plains, eskers, kames, varves, and glaciofluvial sediments. The term is generally applied to Pleistocene glacial deposits in areas that no longer contain glaciers. Drumlin A low, smooth, elongated oval hill, mound, or ridge of compact till that has a core of bedrock or drift. It commonly has a blunt nose facing the direction from which the ice approached and a gentler slope tapering in the other direction. The longer axis is parallel to the general direction of glacier flow. Drumlins are products of 25 Custom Soil Resource Report streamline (laminar) flow of glaciers, which molded the subglacial floor through a combination of erosion and deposition. Duff A generally firm organic layer on the surface of mineral soils. It consists of fallen plant material that is in the process of decomposition and includes everything from the litter on the surface to underlying pure humus. Dune A low mound, ridge, bank, or hill of loose, windblown granular material (generally sand), either barren and capable of movement from place to place or covered and stabilized with vegetation but retaining its characteristic shape. Earthy fill See Mine spoil. Ecological site An area where climate, soil, and relief are sufficiently uniform to produce a distinct natural plant community. An ecological site is the product of all the environmental factors responsible for its development. It is typified by an association of species that differ from those on other ecological sites in kind and/or proportion of species or in total production. Eluviation The movement of material in true solution or colloidal suspension from one place to another within the soil. Soil horizons that have lost material through eluviation are eluvial; those that have received material are illuvial. Endosaturation A type of saturation of the soil in which all horizons between the upper boundary of saturation and a depth of 2 meters are saturated. Eolian deposit Sand-, silt-, or clay -sized clastic material transported and deposited primarily by wind, commonly in the form of a dune or a sheet of sand or loess.

Episaturation A type of saturation indicating a perched water table in a soil in which saturated layers are underlain by one or more unsaturated layers within 2 meters of the surface. Erosion The wearing away of the land surface by water, wind, ice, or other geologic agents and by such processes as gravitational creep. 26 Custom Soil Resource Report Erosion (accelerated) Erosion much more rapid than geologic erosion, mainly as a result of human or animal activities or of a catastrophe in nature, such as a fire, that exposes the surface. Erosion (geologic) Erosion caused by geologic processes acting over long geologic periods and resulting in the wearing away of mountains and the building up of such landscape features as flood plains and coastal plains. Synonym: natural erosion. Erosion pavement A surficial lag concentration or layer of gravel and other rock fragments that remains on the soil surface after sheet or rill erosion or wind has removed the finer soil particles and that tends to protect the underlying soil from further erosion. Erosion surface A land surface shaped by the action of erosion, especially by running water. Escarpment A relatively continuous and steep slope or cliff breaking the general continuity of more gently sloping land surfaces and resulting from erosion or faulting. Most commonly applied to cliffs produced by differential erosion. Synonym: scarp. Escarpment, bedrock (map symbol) A relatively continuous and steep slope or cliff, produced by erosion or faulting, that breaks the general continuity of more gently sloping land surfaces. Exposed material is hard or soft bedrock. Escarpment, nonbedrock (map symbol) A relatively continuous and steep slope or cliff, generally produced by erosion but in some places produced by faulting, that breaks the continuity of more gently sloping land surfaces. Exposed earthy material is nonsoil or very shallow soil. Esker A long, narrow, sinuous, steep -sided ridge of stratified sand and gravel deposited as the bed of a stream flowing in an ice tunnel within or below the ice (subglacial) or between ice walls on top of the ice of a wasting glacier and left behind as high ground when the ice melted.

Examples include backswamps, flood -plain splays, meanders, meander belts, meander scrolls, oxbow lakes, and natural levees. Flood -plain splay A fan -shaped deposit or other outspread deposit formed where an overloaded stream breaks through a levee (natural or artificial) and deposits its material (commonly coarse grained) on the flood plain. Hood -plain step An essentially flat, terrace -like alluvial surface within a valley that is frequently covered by floodwater from the present stream; any approximately horizontal surface still actively modified by fluvial scour and/or deposition. May occur individually or as a series of steps. Fluvial Of or pertaining to rivers or streams; produced by stream or river action.

Forest type A stand of trees similar in composition and development because of given physical and biological factors by which it may be differentiated from other stands. Fragipan A loamy, brittle subsurface horizon low in porosity and content of organic matter and low or moderate in clay but high in silt or very fine sand. A fragipan appears cemented and restricts roots. When dry, it is hard or very hard and has a higher bulk density than the horizon or horizons above. When moist, it tends to rupture suddenly under pressure rather than to deform slowly. 29 Custom Soil Resource Report Genesis, soil The mode of origin of the soil. Refers especially to the processes or soil -forming factors responsible for the formation of the solum, or true soil, from the unconsolidated parent material. GiIgai Commonly, a succession of microbasins and microknolls in nearly level areas or of microvalleys and microridges parallel with the slope. Typically, the microrelief of clayey soils that shrink and swell considerably with changes in moisture content. Glaciofluvial deposits Material moved by glaciers and subsequently sorted and deposited by streams flowing from the melting ice. The deposits are stratified and occur in the form of outwash plains, valley trains, deltas, kames, eskers, and kame terraces. Glaciolacustrine deposits Material ranging from fine clay to sand derived from glaciers and deposited in glacial lakes mainly by glacial meltwater. Many deposits are bedded or laminated. Gleyed soil Soil that formed under poor drainage, resulting in the reduction of iron and other elements in the profile and in gray colors. Graded striperopping Growing crops in strips that grade toward a protected waterway.

Ground water Water filling all the unblocked pores of the material below the water table. Gully (map symbol) A small channel with steep sides caused by erosion and cut in unconsolidated materials by concentrated but intermittent flow of water. The distinction between a gully and a rill is one of depth. A gully generally is an obstacle to farm machinery and is too deep to be obliterated by ordinary tillage; a rill is of lesser depth and can be smoothed over by ordinary tillage. Hard bedrock Bedrock that cannot be excavated except by blasting or by the use of special equipment that is not commonly used in construction. Hard to reclaim Reclamation is difficult after the removal of soil for construction and other uses. Revegetation and erosion control are extremely difficult. Hardpan A hardened or cemented soil horizon, or layer. The soil material is sandy, loamy, or clayey and is cemented by iron oxide, silica, calcium carbonate, or other substance. Head slope (geomorphology) A geomorphic component of hills consisting of a laterally concave area of a hillside, especially at the head of a drainageway. The overland waterflow is converging. Hemic soil material (mucky peat) Organic soil material intermediate in degree of decomposition between the less decomposed fibric material and the more decomposed sapric material.

These crops return large amounts of organic matter to the soil. Hill A generic term for an elevated area of the land surface, rising as much as 1,000 feet above surrounding lowlands, commonly of limited summit area and having a well defined outline. Slopes are generally more than 15 percent. The distinction between a hill and a mountain is arbitrary and may depend on local usage. 31 Custom Soil Resource Report Hiltslope A generic term for the steeper part of a hill between its summit and the drainage line, valley flat, or depression floor at the base of a hill. Horizon, soil A layer of soil, approximately parallel to the surface, having distinct characteristics produced by soil -forming processes. In the identification of soil horizons, an uppercase letter represents the major horizons. Numbers or lowercase letters that follow represent subdivisions of the major horizons. An explanation of the subdivisions is given in the `Soil Survey Manual." The major horizons of mineral soil are as follows: O horizon: An organic layer of fresh and decaying plant residue. L horizon: A layer of organic and mineral limnic materials, including coprogenous earth (sedimentary peat), diatomaceous earth, and marl. A horizon: The mineral horizon at or near the surface in which an accumulation of humified organic matter is mixed with the mineral material. Also, a plowed surface horizon, most of which was originally part of a B horizon. E horizon: The mineral horizon in which the main feature is loss of silicate clay, iron, aluminum, or some combination of these. B horizon: The mineral horizon below an A horizon. The B horizon is in part a layer of transition from the overlying A to the underlying C horizon. The B horizon also has distinctive characteristics, such as (1) accumulation of clay, sesquioxides, humus, or a combination of these; (2) prismatic or blocky structure; (3) redder or browner colors than those in the A horizon; or (4) a combination of these. C horizon: The mineral horizon or layer, excluding indurated bedrock, that is little affected by soil -forming processes and does not have the properties typical of the overlying soil material. The material of a C horizon may be either like or unlike that in which the solum formed. If the material is known to differ from that in the solum, an Arabic numeral, commonly a 2, precedes the letter C. Cr horizon: Soft, consolidated bedrock beneath the soil. R Layer: Consolidated bedrock beneath the soil. The bedrock commonly underlies a C horizon, but it can be directly below an A or a B horizon. M layer:: A root -limiting subsoil layer consisting of nearly continuous, horizontally oriented, human -manufactured materials. W layer: A layer of water within or beneath the soil. Humus The well decomposed, more or less stable part of the organic matter in mineral soils. Hydrologic soil groups Refers to soils grouped according to their runoff potential. The soil properties that influence this potential are those that affect the minimum rate of water infiltration on a bare soil during periods after prolonged wetting when the soil is not frozen. These properties include depth to a seasonal high water table, the infiltration rate, and depth to a layer that significantly restricts the downward movement of water. The slope and the kind of plant cover are not considered but are separate factors in predicting runoff. 32 Custom Soil Resource Report Igneous rock Rock that was formed by cooling and solidification of magma and that has not been changed appreciably by weathering since its formation.

Generally, material is removed from an upper horizon and deposited in a lower horizon. Impervious soil A soil through which water, air, or roots penetrate slowly or not at all. No soil is absolutely impervious to air and water all the time. Increasers Species in the climax vegetation that increase in amount as the more desirable plants are reduced by close grazing. Increasers commonly are the shorter plants and the less palatable to livestock. Infiltration The downward entry of water into the immediate surface of soil or other material, as contrasted with percolation, which is movement of water through soil layers or material. Infiltration capacity The maximum rate at which water can infiltrate into a soil under a given set of conditions. Infiltration rate The rate at which water penetrates the surface of the soil at any given instant, usually expressed in inches per hour. The rate can be limited by the infiltration capacity of the soil or the rate at which water is applied at the surface. Intake rate The average rate of water entering the soil under irrigation. Most soils have a fast initial rate; the rate decreases with application time. Therefore, intake rate for design purposes is not a constant but is a variable depending on the net irrigation application. The rate of water intake, in inches per hour, is expressed as follows: Very low: Less than 0.2 Low: 0.2 to 0.4 Moderately low: 0.4 to 0.75 Moderate: 0.75 to 1.25 Moderately high: 1.25 to 1.75 High: 1.75 to 2.5 Very high: More than 2.5 33 Custom Soil Resource Report Interfluve A landform composed of the relatively undissected upland or ridge between two adjacent valleys containing streams flowing in the same general direction.

Intermittent stream A stream, or reach of a stream, that does not flow year-round but that is commonly dry for 3 or more months out of 12 and whose channel is generally below the local water table. It flows only during wet periods or when it receives ground -water discharge or long, continued contributions from melting snow or other surface and shallow subsurface sources. Invaders On range, plants that encroach into an area and grow after the climax vegetation has been reduced by grazing. Generally, plants invade following disturbance of the surface.

Methods of irrigation are: Basin: Water is applied rapidly to nearly level plains surrounded by levees or dikes. Border: Water is applied at the upper end of a strip in which the lateral flow of water is controlled by small earth ridges called border dikes, or borders. Controlled flooding: Water is released at intervals from closely spaced field ditches and distributed uniformly over the field. Corrugation: Water is applied to small, closely spaced furrows or ditches in fields of close -growing crops or in orchards so that it flows in only one direction. Drip (ortrickle): Water is applied slowly and under low pressure to the surface of the soil or into the soil through such applicators as emitters, porous tubing, or perforated pipe. Furrow: Water is applied in small ditches made by cultivation implements. Furrows are used for tree and row crops. Sprinkler: Water is sprayed over the soil surface through pipes or nozzles from a pressure system. Subirrigation: Water is applied in open ditches or tile lines until the water table is raised enough to wet the soil. Wild flooding: Water, released at high points, is allowed to flow onto an area without controlled distribution. 34 Custom Soil Resource Report Kame A low mound, knob, hummock, or short irregular ridge composed of stratified sand and gravel deposited by a subglacial stream as a fan or delta at the margin of a melting glacier; by a supraglacial stream in a low place or hole on the surface of the glacier; or as a ponded deposit on the surface or at the margin of stagnant ice.

Temporary flooding occurs primarily in response to precipitation and runoff. Playa deposits are fine grained and may or may not have a high water table and saline conditions. Plinthite The sesquioxide-rich, humus -poor, highly weathered mixture of clay with quartz and other diluents. It commonly appears as red mottles, usually in platy, polygonal, or reticulate patterns. Plinthite changes irreversibly to an ironstone hardpan or to irregular aggregates on repeated wetting and drying, especially if it is exposed also to heat from the sun. In a moist soil, plinthite can be cut with a spade. It is a form of laterite. Plowpan A compacted layer formed in the soil directly below the plowed layer. Ponding Standing water on soils in closed depressions. Unless the soils are artificially drained, the water can be removed only by percolation or evapotranspiration.

Redoximorphic concentrations See Redoximorphic features. Redoximorphic depletions See Redoximorphic features. Redoximorphic features Redoximorphic features are associated with wetness and result from alternating periods of reduction and oxidation of iron and manganese compounds in the soil. Reduction occurs during saturation with water, and oxidation occurs when the soil is not saturated. Characteristic color patterns are created by these processes. The reduced iron and manganese ions may be removed from a soil if vertical or lateral fluxes of water occur, in which case there is no iron or manganese precipitation in that soil. Wherever the iron and manganese are oxidized and precipitated, they 43 Custom Soil Resource Report form either soft masses or hard concretions or nodules. Movement of iron and manganese as a result of redoximorphic processes in a soil may result in redoximorphic features that are defined as follows: 1. Redoximorphic concentrations.—These are zones of apparent accumulation of iron -manganese oxides, including: 2. Redoximorphic depletions.—These are zones of low chroma (chromes less than those in the matrix) where either iron -manganese oxides alone or both iron -manganese oxides and clay have been stripped out, including: 3.

Sinkhole (map symbol) A closed, circular or elliptical depression, commonly funnel shaped, characterized by subsurface drainage and formed either by dissolution of the surface of underlying bedrock (e.g., limestone, gypsum, or salt) or by collapse of underlying caves within bedrock. Complexes of sinkholes in carbonate -rock terrain are the main components of karst topography. Site Index A designation of the quality of a forest site based on the height of the dominant stand at an arbitrarily chosen age. For example, if the average height attained by dominant and codominant trees in a fully stocked stand at the age of 50 years is 75 feet, the site index is 75. Slickensides (pedogenic) Grooved, striated, and/or glossy (shiny) slip faces on structural peds, such as wedges; produced by shrink -swell processes, most commonly in soils that have a high content of expansive clays.

Expected maximum flow rates, flow directions, and maximum quantities for individual sites are listed in Appendix A. Bulk Storage Tank Leak or Failure 1. Failure Modes: Corrosion, vandalism, lightning strikes, valve or piping failure, overfilling. Il. Rate of Flow: Variable, depending upon the type, size and location of the tank failure. The ambient temperature at the time of the release may affect the viscosity of the oil and thereby impact the rate of flow, Flow rates for corrosion failure are typically low, ranging from less than a gallon per day to a gallon per hour. Flows resulting from valve and piping failures or vandalism typically range from a gallon per hour up to the tank contents per hour. Lightning strikes may result in a release that Is essentially instantaneous. 111. Discharge Quantity: Variable depending upon the type and location of the failure. The total quantity discharged would not exceed the working capacity of the largest tank. IV. Preventative Measures: Storage tanks are constructed in accordance with API industry standards. Materials used in constructing the tanks are compatible with the substances stored. Where practicable, earthen berms or other diversionary structures are utilized to control any released fluids. Compacted natural clay/loam bases and berms with gravel armor or concrete are utilized for containment in the event of a release from and of this type equipment. The containment areas are constructed to contain a minimum of 100% of the single largest container within the containment structure plus freeboard for precipitation. Tanks are appropriately sized to minimize the risk of overfilling. Tanker Truck Loading and Unloading Operations SPCC Plan Page 6 I. Failure Modes: Piping or valve failure, tank failure, overflow, and human error. I I. Rate of Flow: Variable depending upon the type, size and exact location of the failure, and the amount of oil in the tanker truck and storage tank. The ambient temperature at the time of the release may affect the viscosity of the oil and thereby impact the rate of flow. Flow rates resulting from piping and valve failures can range from 1 gallon per hour up to the tank contents in less than one hour. The flow rate for tank truck overflows typically will not exceed 5 to 10 bbls per minute. Tank failures may result in releases that are essentially instantaneous. III, Discharge Quantity: Variable depending upon the type and location of the failure. The total quantity discharged would not exceed the working capacity of the largest tank. IV. Preventative Measures: Oil production is removed from the facility by truck. Tanker truck loading and unloading operations are conducted in accordance with United States Department of Transportation regulations (49 CFR 177). All loading operations are attended by the truck driver. No smoking or open flames are allowed In the vicinity of the storage tanks and loading area. Following the completion of loading operations, the transfer line is disconnected and all valves and outlets on the tanker truck and the storage tank are visually inspected for leakage prior to vehicle departure. Process Unit Failure (Separator/Heater Treater/Gun Barrel) Failure Modes: Process vessels may rupture or associated lines, valves and gauges may fail or leak. Leaks from corrosion or at valves and connections. If pressure relief valves dump to a flare or vent, this may result in a release. II. Rate of Flow: Variable, depending upon the mode and extent of the failure. The maximum expected rate of flow from a process unit failure is the oil production rate of the well plus any additional fluid volume contained in the vessel above the elevation of the rupture. III. Discharge Quantity: Variable, depending on the type of failure and the length of time that the failure went undetected. VI. Preventative Measures: Process units are constructed in accordance with API and ASME industry standards. Where practicable, earthen berms or other diversionary structures are utilized to control any released fluids. Piping Failure I. Failure Modes: Both aboveground and buried pipelines may rupture or corrode and leak. Associated flanges, screwed connections, valves and gauges are also subject to corrosion and may fail or leak. Piping may be damaged from construction activities. At the wellhead, there may be leaks at the stuffing box, valves, and connections. II. Rate of Flow: Variable, depending on the size and location of the piping -related failure. The maximum potential rate of flow is not expected to exceed the oil production rate. III. Discharge Quantity: Variable depending upon the type and extent of the failure and the length of time that the failure went undetected. IV. Prevention Measures: Flowlines to the tank battery are steel and/or poly pipe. Flowlines are typically buried and secondary containment Is not practicable. Corrosion inhibitor is utilized to prevent SPCC Plan Page 7 corrosion. During pipeline excavation projects pipelines are inspected for signs of excessive corrosion or stress. Personnel routinely perform visual inspections of aboveground piping and buried flowline right-of- ways ight-ofways to detect leaks and/or failures. Lines are repaired or replaced as appropriate if leaks, failures, excessive corrosion or stress are indicated. 2.8 Containment and/or Diversionary Structures [112.7(c)] The aboveground storage tanks have berms for secondary containment. Secondary containment for truck loading/unloading area, separation equipment, and piping is not practicable In many instances. See Appendix A for site-specific information. See Appendix B for the oil spill contingency plan. Contact information for company personnel, cleanup and other contractors, and government regulatory agencies is included in Appendix C. The central depot for spial response equipment is the Field Office. Granular absorbent material, pads, booms, shovels, brooms, earthmoving equipment for spill containment, and empty drums are available for dispatch from this site. 011 transport trucks, including contract oil haulers, carry spill control kits. 3.0 INSPECTIONS PROCEDURES (112.7 e) The pumper will informally inspect the production equipment in his area on each visit (daily to weekly).

Prior to drainage, you must inspect the diked area and take action as provided in ,¢ 112.8(c)(3)(ii), (iii), and (iv). You must remove accumulated oil on the rainwater and return it to storage or dispose of it in accordance with legally approved methods. (2) Inspect at regularly scheduled intervals field drainage systems (such as drainage ditches or road ditches), and oil traps, sumps, or skimmers, for an accumulation of oil that may have resulted from any small discharge. You must promptly remove any accumulations of oil. SPCC Plan Page 10 a. Drainage from diked storage areas Is controlled as follows: 112.9(b) (1) The containment areas are inspected several times per week when operating personnel visit the site. Any accumulation of oil resulting from a discharge is promptly removed. No drainage from containment areas should be required. Water accumulated in the bermed areas will be inspected to insure compliance with applicable water quality standards and will not create a harmful discharge as defined in 40 CFR part 110.3 which includes oil that causes a film or sheen upon or discoloration of the surface of the water. If necessary, fluids within the containment area will be recovered and placed back into the production system or taken to an approved disposal site. Personnel must record any drainage events, including date, hydrocarbons present, and volume drained. A Stormwater Inspection Procedure and Drainage Record Form is presented In Appendix F. b. Drainage from undiked areas is controlled as follows: 112.9(b) (2) Hydrocarbon storage vessels are located within bermed areas to prevent spills into undiked areas. Field drainage dikes and road ditches will be inspected for accumulation of oil or oil contaminated soil. 7.0 BULK STORAGE CONTAINERS/SECONDARY CONTAINMENT [112.9(c)] 7.1 Tank compatibility with its contents: 11 2.9(c)(1) Not use a container for the storage of oil unless its material and construction are compatible with the material stored and the conditions of storage. The ASTs onsite are constructed of welded steel in accordance with API standards. The tanks are specifically designed to hold oil and/or water and the materials of construction are compatible with the contents. 7.2 Secondary containment: 112.9(c)(2) Provide all tank battery, separation, and treating facility installations with a secondary means of containment for the entire capacity of the largest single container and suj icient freeboard to contain precipitation. You must safely confine drainage from undiked areas in a catchment basin or holding pond. The permanent secondary containment has been designed to hold the entire contents of the largest tank with sufficient freeboard to allow for precipitation. The gas/liquid separator and associated piping do not have secondary containment, but the facility is covered by an oil spill contingency plan and a commitment of manpower, equipment, and materials. SPCC Plan Page 11 7.3 Container Inspection 1129(c)(3) Periodically and upon a regular schedule visually inspect each container of oil for deterioration and maintenance needs, including the foundation and support of each container that is on or above the surface of the ground. Personnel view and informally inspect aboveground storage tanks several times per week as part of their routine maintenance schedule. Aboveground storage tanks, secondary containment and associated equipment are formally inspected on an annual basis. During these inspections, the outside of each tank is observed for evidence of deterioration, Teaks which might cause a spill, or accumulation of oil inside diked areas. These annual facility inspections are documented. A sample facility inspection form is presented in Appendix D. 7.4 Tank Battery Engineering 112.9(c) (4) Engineer or update new and old tank battery installations in accordance with good engineering practice to prevent discharges. You must provide at least one of the following: (1) Container capacity adequate to assure that a container will not overfill if a pumper/gauger is delayed in making regularly scheduled rounds, (11) Overflow equalizing lines between containers so that a full container can overflow to an adjacent container. (iii) Vacuum protection adequate to prevent container collapse during a pipeline run or other transfer of oil from the container. (iv) High level sensors to generate and transmit an alarm signal to the computer where the facility is subject to a computer production control system.

SPCC Plan APPENDIX B OIL SPILL CONTINGENCY PLANS AND WRITTEN COMMITMENT OF MANPOWER, EQUIPMENT, AND MATERIALS SPCC Pian BBC OIL SPILL CONTINGENCY PLANS AND WRITTEN COMMITMENT OF MANPOWER, EQUIPMENT, AND MATERIALS Secondary containment or diversionary structures are impracticable for portions of this facility for the following reasons (attach additional pages if necessary): All aboveground oil storage tanks at this facility are contained within diked areas. Secondary Containment for line treaters, separation units, oil loading areas, and underground flowlines may be impracticable at this facility for the following reasons: 1) All line treaters and separation vessels at newly constructed batteries are ASME coded flow- through process vessels and are NOT oil storage vessels. 2) Secondary containment diking around fired line treaters may represent a safety hazard, 3) The most likely type release from line treaters or separation units is a pressure release from the "pop-off" valve discharging gas rather than crude oil. 4) A safe and effective dike system would be difficult to design and impracticable to construct for loading areas, line treaters, separation vessels, and flowlines. 5) Underground #iowiines typically operate at much less than their rated pressure. 6) Extensive diking and/or drainage trenches would interfere with site access for normal operations and also with current surface land uses. Extensive diking and/or trenching may represent a physical hazard as well as an impediment to emergency response equipment and personnel. A spill contingency plan is in effect for This facility in the event of an oil spilt. YES An oil spill contingency plan is attached. YES A written commitment of manpower is attached to the spill contingency plan. YES SPCC Plan Page B-1 BBC OIL SPILL CONTROL AND CONTINGENCY PLAN FORWARD Constant vigilance and a personal dedication to protection of the environment should be the goal of every BBC employee. Every safeguard should be taken to prevent the accidental discharge of oil to soil or water, and immediate response to oil spills is every employee's responsibility. Preventive action is our best measure to hold oil discharges to a minimum and reduce the potential pollution danger. The following contingency plan forms the basis to meet this challenge. This alert procedure becomes effective immediately upon the observance of or hearing of an oil spill from any company facilities. Any employee observing or receiving knowledge of an oil spill must immediately take actions to minimize injuries and damage and notify the designated person. Make sure all steps taken are in accordance with good safety practices. The priority in ail circumstances will be to protect life. SPCC Plan Page B-2 BILL BARRETT CORP. OIL SPILL CONTROL AND CONTINGENCY PLAN 1. PURPOSE Establish procedures to minimize damage caused by pollution from an accidental oil discharge. 11. GENERAL A. Operating personnel will become familiar with these procedures and take corrective action in the event of an oil spill. B. As a preventive measure, be alert for and eliminate potential pollution hazards. 111. RESPONSE PROCEDURES A. Upon detecting an oil spill, the person making the discovery should: 1. Determine the source of the leak. 2. Attempt to stop the source of the leak, if it can be done safely. 3. Notify the responsible person and the EH&S Dept. that an oil spill has occurred, and alert the foreman of corrective action taken or required. B. For minor spill events not endangering surface or ground water, the Production Foreman shall: 1. Contact the EH&S Dept. 2. Direct safe clean-up of the oil spill. 3. Arrange for necessary repairs. C. For major spills and spills which endanger surface or ground water, the Production Foreman shall: 1. Mobilize Environmental Emergency Response Equipment and Contractors 2. Contact the EH&S Dept. 3. Direct safe clean-up and arrange for additional equipment, material and manpower as needed. 4. Arrange for necessary repairs. D. Containment, Cleanup and Restoration The general procedures outlined below will normally be followed for spills in most areas. Only approach a spill if you are certain it is SAFE to do so. If you are not sure it is safe wail for additional personnel and/or equipment. 1. Land Oil Spill a. Construct earthen berms or shallow catchment pits with the appropriate equipment to contain the oil. b_ Remove any free oil with absorbent materials or vacuum trucks. c. Affected soils will either be treated or transported to an approved disposal facility. d. Dispose of all oil -soaked materials (e.g. hay, absorbent cloths or booms) in an approved manner. e. Restore the land area, as nearly as possible, to original conditions. 2. Surface Water Oil Spill SPCC Plan Page B-3 a. If possible, construct an earthen dam downstream of the oil spill (river or stream spills only). b. Allow water past the dam using an undertow pipe, if possible. c. If it is impractical to build an earthen darn, place an olI-absorbent boom downstream or outside of the extent of the oil spill area. d. If possible, construct a backstop downstream of the dam/boom using fence posts and some type of fencing material. Place a boom in the backstop to absorb residual traces of oil on the water surface. e. Remove any free oil from the water surface between the dam/boom and spill using absorbents or a vacuum truck. f. Physically dean the bank areas to prevent any residual oil from entering the water. g. Dispose of all oil -soaked materials (e.g. hay, absorbent cloths or booms) in an approved manner. h. Restore the land area, as nearly as possible, to original conditions. IV. MANPOWER AND EQUIPMENT AVAILABILITY A. Company Personnel In the event of an oil spill, all employees will be utilized as necessary for containment and clean- up. The company personnel used to respond to an oil spill at the site are Identified in Appendix C. They will provide oversight in the containment, removal, and remediation of any spilled material. They will also assist and supervise in the maintenance of site security to insure only authorized persons are allowed within the site area during response operations. B. Company Equipment 1.

Name Signature Company Job Title SPCC Plan APPENDIX F STORMWATER INSPECTION PROCEDURE AND DRAINAGE RECORD SPCC Plan STORMWATER INSPECTION PROCEDURE AND DRAINAGE RECORD Earthen berms, containment rings, and other containment structures are inspected on a regular basis for accumulations of oil and precipitation. These inspections are not typically documented. Generally, drainage from containment structures is not conducted. Minor accumulations of precipitation are allowed to evaporate. Large accumulations of fluids may be removed by vacuum truck and either returned to a separation vessel for processing or transported to a permitted recovery/disposal facility. In the unlikely event that drainage events are conducted, the accumulated stormwater is visually inspected for contamination from oil. NO oil is released from or pumped from within the berm onto the ground or into a water course. Drainage or pumping does not occur until the fluids have been inspected for oil. Draining only occurs with constant visual supervision of the drain outlet, and only after determining that the water is indeed fresh. Draining ceases at the first sign of an oil sheen and the remaining fluid is removed and properly treated or disposed. The foreman in charge of the facility operations is consulted before any berm is drained or purged. As required by law, any time that stormwater is discharged from the dike, a record of the inspection, discharge and oil removal is to be maintained. The following is the discharge record: Date of Discharge Oil Sheen Present Inspector's Signature Comments $PCC Plan APPENDIX G CERTIFICATION OF APPLICABILITY OF SUBSTANTIAL HARM CRITERIA SPCC Plan Appendix E Certification of the Applicability of the Substantial Harm Criteria Checklist Facility Name: EAST MAMM CREEK FIELD PLAN Facility Address: SOUTH OF SILT, COLORADO, GARFILED COUNTY, COLORADO 1.

Authority to Discharge PART 1 Permit - Page 3 Permit No. COR -030000 Under this permit, facilities are granted authorization to discharge stormwater associated with construction activities into waters of the state of Colorado. This permit also authorizes the discharge of specific allowable non-stormwater discharges, in accordance with Part I.D.3 of the permit, which includes discharges to the ground. This includes stormwater discharges from areas that are dedicated to producing earthen materials, such as soils, sand and gravel, for use at a single construction site (i.e., borrow or fill areas). This permit also authorizes stormwater discharges from dedicated asphalt batch plants and dedicated concrete batch plants. (Coverage under the construction site permit is not required for batch plants if they have alternate CDPS permit coverage.) This permit does not authorize the discharge of mine water or process water from such areas. a) Applicable Sections: In accordance with Part I.A.3 of this permit, some parts of this permit do not apply to sites covered under a Qualifying Local Program, as defined in 1.A.2.d. For sites not covered by a Qualifying Local Program, all parts of the permit apply except Part I.A.3. 'fhe permittee will be responsible for determining and then complying with the applicable sections. b) Oil and Gas Construction: Stormwater discharges associated with construction activities directly related to oil and gas exploration, production, processing, and treatment operations or transmission facilities are regulated under the Colorado Discharge Permit System Regulations (5CCR 1002-61), and require coverage under this permit in accordance with that regulation. However, references in this permit to specific authority under the Federal Clean Water Act (CWA) do not apply to stormwater discharges associated with these oil and gas related construction activities, to the extent that the references are limited by the federal Energy Policy Act of 2005. 2. Definitions a) Stormwater: Stormwater is precipitation -induced surface runoff. b) Construction activity: Construction activity refers to ground surface disturbing activities, which include, but are not limited to, clearing, grading, excavation, demolition, installation of new or improved haul roads and access roads, staging areas, stockpiling of fill materials, and borrow areas. Construction does not include routine maintenance to maintain original line and grade, hydraulic capacity, or original purpose of the facility. c) Small construction activity: Stormwater discharge associated with small construction activity ineans the discharge of stormwater from construction activities that result in land disturbance of equal to or greater than one acre and less than five acres. Small construction activity also includes the disturbance of less than one acre of total land area that is part of a larger common plan of development or sale, if the larger common plan will ultimately disturb equal to or greater than one and Tess than five acres. d) Qualifying Local Program: This permit includes conditions that incorporate qualifying local erosion and sediment control program (Qualifying Local Program) requirements by reference. A Qualifying Local Program is a municipal stormwater program for stormwater discharges associated with small construction activity that has been formally approved by the Division. Other Definitions: Definitions of additional terms can be found in Part I.E. of this permit. 3. Permit Coverage Without Application — for small construction activities under a Qualifying Local Program only If a small construction site is within the jurisdiction of a Qualifying Local Program, the operator of the construction activity is authorized to discharge stormwater associated with small construction activity under this general permit without the submittal of an application to the Division. a) Applicable Sections: For sites covered by a Qualifying Local Program, only Parts 1.A.1, 1.A.2, 1.A.3, 1.D.1, 1.D.2, 1.0a, I.D.4, 1.D.7, 1.0.8, 1.0.11, I.E and Part I1 of this permit, with the exception of Parts II.A.1, I1.B,3, II.B,8, and 11.B10, apply. PART I Page 4 Permit No. COR -030000 1. COVERAGE UNDER THIS PERMIT (cont.) c) Permit Coverage Termination: When a site has been finally stabilized, coverage under this permit is automatically terminated. d) Compliance with Qualifying Local Program: A construction site operator that has authorization to discharge under this permit under Part I.A.3 shall comply with the requirements of the Qualifying Local Program with jurisdiction over the site. e) Full Permit Applicability: The Division may require any owner or operator within the jurisdiction of a Qualifying Local Program covered under this permit to apply for and obtain coverage under the full requirements of this permit. The owner or operator must be notified in writing that an application for full coverage is required. When a permit certification under this permit is issued to an owner or operator that would otherwise be covered under Part I.A.3 of this permit, the full requirements of this permit replace the requirements as per Part I.A.3 of this permit, upon the effective date of the permit certification. A site brought under the full requirements of this permit must still comply with local stormwater management requirements, policies or guidelines as required by Part I.C.I .h of this Permit. 4. Application. Due Dates a) Application Due Dates: At least ten days prior to the commencement of construction activities, the operator of the construction activity shall submit an application form as provided by the Division, with a certification that the Stormwater Management Plan (SWMP) is complete. One original completed discharge permit application shall be submitted, by mail or hand delivery, to: Colorado Department of Public Health and Environment Water Quality Control Division WQCD-P-B2 4300 Cherry Creek Drive South Denver, Colorado 80246-1530 b) Summary of Application: The application requires, at a minimum, the following: 1) The operator's name, address, telephone number, tax payer identification number (or employer identification number), and the status as Federal. State, private, public or other entity; 2) Name, county and location of the construction site, including the latitude and longitude to the nearest 15 seconds of the approximate center of the construction activity; 3) A brief description of the nature of the construction activity; 4) The anticipated starting date of the project and the anticipated schedule of completion 5) Estimates of the total area of the site, the area of the site that is expected to be disturbed, and the total area of the larger common plan of development or sale to undergo disturbance; 6) The name of the receiving water(s), or the municipal separate storm sewer system and the ultimate (i.e., named) receiving water(s); 7) Certification that the SWMP for the construction site is complete (see Part I.B. below); and 8) The signature of the applicant signed in accordance with Part I.E.1 of this permit. 5. Permit Certification Procedures If the general permit is applicable to the applicant's operation, then a certification will be developed and the applicant will be authorized to discharge stormwater under this general permit. PART 1 Page 5 Permit No. COR -030000 A. COVERAGE UNDER THIS PERMIT (cont.) a) Request for Additional Information: The Division shall have up to ten days after receipt of the above information to request additional data andior deny the authorization for any particular discharge. Upon receipt of additional information, the Division shall have an additional ten days to issue or deny authorization for the particular discharge. (Notification of denial shall be by letter, in cases where coverage under an alternate general permit or an individual permit is required, instead of coverage under this permit.) b) Automatic Coverage: If the applicant does not receive a request for additional information or a notification of denial from the Division dated within ten days of receipt of the application by the Division, authorization to discharge in accordance with the conditions of this permit shall be deemed granted. c) Individual Permit Required: If, after evaluation of the application (or additional information, such as the SWMP), it is found that this general permit is not applicable to the operation, then the application will be processed as one for an individual permit. The applicant will be notified of the Division's decision to deny certification under this general permit. For an individual permit, additional information may be requested, and 180 days will be required to process the application and issue the permit. d) Temporary Coverage: Notwithstanding Parts I.A.5.a-c, above, the Division reserves the right to temporarily cover stormwater discharge from construction activity under general permits, even though individual permit coverage may be more appropriate. Certification of these activities under a general permit does not m any way infringe on the Division's right to revoke that coverage and issue an individual permit or amend an existing individual permit. e) General vs. Individual Permit Coverage: Any owner or operator authorized by this permit may request to be excluded from the coverage of this permit by applying for an individual CDPS permit. The owner or operator shall submit an individual application, with reasons supporting the request, to the Division at least 180 days prior to any discharge. f) Local Agency Authority: This permit does not pre-empt or supersede the authority of local agencies to prohibit, restrict, or control discharges of stormwater to storm drain systems or other water courses within their jurisdiction. 6. Inactivation Notice When a site has been finally stabilized in accordance with the SWMP, the operator of the facility must submit an Inactivation Notice that is signed in accordance with Part I.E.I. of this permit. The Inactivation Notice form is available from the Division and includes: a) Permit certification number; b) The permittee's name, address, telephone number; c) Name, location, and county for the construction site for which the application is being submitted. d) Certification that the site has been finally stabilized, and a description of the final stabilization method(s). An inactivation form may not be required for small construction activities if application was made for coverage with a completion date less than 12 months from the start of construction activity. In such cases, permit certification may be authorized for a predetermined period from 3 to 12 months. The permit certification will include the automatic expiration date for permit coverage. If permit coverage beyond that date is needed (i.e., the site has not been finally stabilized), the permittee must submit an extension request form to the Division at least 10 days prior to the expiration date. 7. Transfer of Permit When responsibility for stormwater discharges at a construction site changes from one individual to another, the permittee shall submit a completed Notice of Transfer and Acceptance of Terms of a Construction General Stormwater Discharge Permit Certification that is signed in accordance with Part I.E.1. of this permit. The Notice of Transfer form is available from the Division and includes: PART 1 Page 6 Permit No. COR -030000 COVERAGE UNDER THIS PERMIT (cont.) a) Permit certification number. b) Name, location, and county for the construction site for which the application is being submitted. c) The current permittee's name, address, telephone number and the status as Federal, State, private, public or other entity. d) The new permittee's name, address and telephone number and the status as Federal, State, private, public or other entity. e) Certification that the new permittee has reviewed the permit and SWMP and accepts responsibility, coverage and liability for the permit. f) Effective date of transfer. If the new responsible party will not complete the transfer form, the permit may be inactivated if the permittee has no legal responsibility, through ownership or contract, for the construction activities at the site. In this case, the new operator would be required to obtain permit coverage separately. 8. Permit Expiration Date Authorization to discharge under this general permit shall expire on June 30, 2007. The Division must evaluate and reissue this general permit at least once every five years and must recertify the applicant's authority to discharge under the general permit at such time. Any permittee desiring continued coverage under the general permit must reapply by March 31, 2007. The Division will determine if the applicant may continue to operate under the terms of the general permit. An individual permit will be required for any facility not reauthorized to discharge under the reissued general permit. 9. Individual Permit Criteria Aside from the activity type, the Division may use other criteria in evaluating whether an individual permit is required instead of this general permit. This information may come from the application, SWMP, or additional information as requested by the Division, and includes, but is not limited to, the following: a) the quality of the receiving waters (i.e., the presence of downstream drinking water intakes or a high quality fishery, or for preservation of high quality water); b) the size of the construction site; c) evidence of noncompliance under a previous permit for the operation; d) the use of chemicals within the stormwater system. In addition, an individual permit may be required when the Division has shown or has reason to suspect that the stormwater discharge may contribute to a violation of a water quality standard. B. CONTENTS OF THE STORMWATER MANAGEMENT PLAN The SWMP shall be prepared in accordance with good engineering, hydrologic and pollution control practices. (The SWMP need not be prepared by a registered engineer.) The main objective of the plan shall be to identify Best Management Practices (BM's) which when implemented will meet the terrns and conditions of this permit (see Part I.C., below). The plan shall identify potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with construction activity from the facility. In addition, the plan shall describe and ensure the implementation of BMPs which will be used to reduce the pollutants in stormwater discharges associated with construction activity. Construction operations must implement the provisions of the SWMP required under this part as a condition of this permit. The SWMP shall include the following items, at a minimum: PART 1 Page 7 Permit No. COR -030000 B. CONTENTS OF THE STORMWATER MANAGEMENT PLAN (cont.) 1. Site Description Each plan shall provide a description of the following: a) A description of' the construction activity. b) The proposed sequence for major activities. c) Estimates of the total area of the site, and the area of the site that is expected to undergo clearing, excavation or grading. d) An estimate of the runoff coefficient of the site before and after construction activities are completed and any existing data describing the soil, soil erosion potential or the quality of any discharge from the site. e) A description of the existing vegetation at the site and an estimate of the percent vegetative ground cover. f) The location and description of any other potential pollution sources, such as vehicle fueling, storage of fertilizers or chemicals, etc. g) The location and description of any anticipated non-stormwater components of the discharge, such as springs and landscape irrigation return flow. h) The name of the receiving water(s) and the size, type and location of any outfall or, if the discharge is to a municipal separate storm sewer, the name of that system, the location of the storm sewer discharge, and the ultimate receiving water(s). Site Map Each plan shall provide a generalized site map or maps which indicate: - construction site boundaries all areas of soil disturbance - areas don and fill areas used for storage of building materials, soils or wastes - location of any dedicated asphalt or concrete batch plants location of major erosion control facilities or structures - springs, streams, wetlands and other surface waters boundaries of 100 -year flood plains, if determined. 3. BMPs for Stormvater Pollution Prevention The plan shall include a narrative description of appropriate controls and measures that will be implemented before and during construction activities at the facility. The plan shall clearly describe the relationship between the phases of construction and the implementation and maintenance of controls and measures. For example, which controls will be implemented during each of the following. stages of construction: clearing and grubbing necessary for perimeter controls, initiation of perimeter controls, remaining clearing and grubbing, road grading, storm drain installation, final grading, stabilization, and removal of control measures. The description of controls shall address the following minimum components: a) Erosion and Sediment Controls. 1) Structural Practices. A description of structural site management practices which will minimize erosion and sediment transport. Practices may include, but are not limited to: straw bales, silt fences, earth dikes, drainage swales, sediment traps, subsurface drains, pipe slope drains, inlet protection, outlet protection, gabions, and temporary or permanent sediment basins. 2) Non -Structural Practices. A description of interim and permanent stabilization practices, including site- specific scheduling of the implementation of the practices. Site plans should ensure that existing vegetation is preserved where possible and that disturbed areas are stabilized. Non-structural practices may include, but are not limited to: temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative buffer strips, protection of trees, and preservation of mature vegetation. PART 1 Page 8 Permit No. COR -030000 CONTENTS OF THE STORMWATER MANAGEMENT PLAN (cont.) b) Materials Handling and Spill Prevention, The SWMP shall identify any procedures or significant materials (see definitions at Part I.D.) handled at the site that could contribute pollutants to runoff. These could include sources such as: exposed storage of building materials, fertilizers or chemicals; waste piles; and equipment maintenance or fueling procedures. Areas or procedures where potential spills can occur shall have spill prevention and response procedures identified. Measures to control stormwater pollution from dedicated concrete batch plants or dedicated asphalt batch plants covered by this certification, must be identified in the SWMP. 4. Final Stabilization and Longterm Stormwater Management The plan shall include a description of the measures used to achieve final stabilization and measures to control pollutants in stormwater discharges that will occur after construction operations have been completed. Final stabilization is reached when all soil disturbing activities at the site have been completed, and uniform vegetative cover has been established with a density of at least 70 percent of pre -disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative cover capable of providing erosion control equivalent to pre- existing conditions at the site can be considered final stabilization. The permittee will be responsible for providing to the Division the documentation to [Hake this comparison. The Division may, after consultation with the permittee and upon good cause, amend the final stabilization criteria for specific operations. S. Other Controls The plan shall include a description of other measures to control pollutants in stormwater discharges, including plans for waste disposal and limiting off-site soil tracking. 6.

INTRODUCTION This permit is for the regulation of stormwater runoff front construction activities. The term "construction activity" includes clearing, grading and excavation operations. "Stormwater" is precipitation -induced surface runoff This Rationale will explain the background of the Stormwater program, activities which are covered under this permit, how to apply for coverage under this permit, and the requirements of this permit. The forms discussed in the Rationale and Permit are available on the Division's website at: littp://www.cdphe,state.ca.za/wq/permitsunit/wqcdpmt.html A. Changes in this General Permit Several notable changes from the previous General Permit for Construction Activities have been incorporated into this permit. Most of the changes are related to the Phase I1 revision to the stormwater regulation in the Colorado Discharge Permit System Regulations (5CCR 1002-61), effective March 2, 2001. Significant changes are listed below: 1. Permit coverage is now required for construction sites that disturb 1 to 5 acres (i.e., small construction activities). Allowances have been made for small construction activities to comply with the requirements of a Division -approved Qual i'ing Local Program (refer to section VI below for a discussion of Oualif_ving Local Programs) in place of many specific requirements in the Permit, including requirements to subndt an application, inactivation notice, and fees to the Division. Refer to Part 1,4.3 of the Permit and section VILA of the Rationale for more details. 2. The requirements to submit with the application the Township, Range, section and quarter section of a site and a list of any other environmental permits for the site have been removed. 3. Inactivation requirements have been changed to allow small construction activities that submit applications indicating a completion date 12 months or less from the start of construction activity to be authorized for a predetermined period font 3 to 12 months. The permit certification will include the automatic expiration date for permit coverage. This expiration date will be in place of the requirement to submit an Inactivation Notice. If permit coverage beyond the expiration date is needed (i.e., the site has not been _finally stabilized), the permittee must submit an extension request form to the Division at least 10 days prior to the expiration. COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division Rationale - Page 2, Permit No. COR -030000 1. INTRODUCTION (cont) �. The Rationale discussion on the Exemptions for Small Municipalities (Section I11.13) has been changed to include the March 10, 2003 deadline for permit coverage for municipally -owned industries. This did not involve any changes to the permit. Il. BACKGROUND As required under the Clean Water Act amendments of 1987, the Environmental Protection Agency (EPA) has established a framework for regulating municipal and industrial stormwater discharges. This framework is under Me National Pollutant Discharge Elimination System (NPDES) program (Note: The Colorado program is referred to as the Colorado Discharge Permit System, or CDPS, instead ofNPDES). The Water Quality Control Division ("the Division') has stormwater regulations (5CCR 1002-61) in place. These regulations require specific types of industrial facilities that discharge stormwater associated with industrial activity (industrial stormwater), to obtain a CDPS permit for such discharge. The regulations specifically, include construction activities that disturb one acre of land or more as industrial facilities. Construction activities that are part of a larger common plan of development which disturb one acre or more over a period of time are also included. A. General Permits The Water Quality Control Division ("the Division'} has determined that the use of general permits is the appropriate procedure for handling the thousands of industrial stormwater applications within the State. B. Permit Requirements This permit does not require submission of effluent monitoring data in the permit application or in the perttit itself. It is believed that a fully implemented Storniwater Management Plan (SWMP) should be sufficient to control water quality impacts. The permit requires dischargers to control and eliminate the sources of pollutants in stormwater through the development and implementation of S6VMP. The plan Hurst include Best Management Practices (BMPs), which will include pollution prevention and source reduction measures. This will constitute BAT and BCT and should achieve compliance with water quality. standards. The narrative permit requirements include prohibitions against discharges of non-stormwater (e.g., process water). Refer to Parr 1.C.2 of the permit. In addition, as a condition of this permit, the permittee is required to pay the annual fee as described in the Water Quality Control Act. Failure to submit the required fee when due and payable is a violation of the permit and will result in enforcement action as discussed below. Pennittees will be billed for the initial permit fee within a few weeks of permit issuance. Some construction activities may be required to comply with a Oualfing Local Program in place of meeting several of the specific requirements in this permit. Sites covered by a Qualifying Local Program may not be required 10 submit an application for coverage or a notice of inactivation and may not be required to pay the annual fee. Refer to Section VILA of the Rationale for further information. C. Violations/Penalties Dischargers of stormwater associated with industrial activity, as defined in the Regulations for the State Discharge Permit System (5CCR 1002-61), which do not obtain coverage under this or other Colorado general permits, or under an individual CDPS permit regulating industrial stormwater, will be in violation of the Federal Clean Water Act and the Colorado Water Quality Control Act, 25-8-101. For facilities covered under a CDPS permit, failure to comply with any CDPS permit requirement constitutes a violation. Civil penalties for violations of the Act or CDPS permit requirements may be up to $10,000 per day. Criminal pollution of state waters is punishable by fines of up to S25,000 per day.

STORMWATER DISCHARGES ASSOCIATED WITH CONSTR UCTIONACTIVITY The Stormwater regulations require that stormwater discharges associated with certain industrial activities be covered under the permit program. Construction activity that disturbs one acre or more during the life of the project is specifically, included in the listed industrial activities. A. Construction Activit' Construction activity includes clearing, grading and excavation activities. Construction does not include routine maintenance performed by public agencies, or their agents to maintain original line and grade, hydraulic capacity, or original purpose of the facility. Definitions of additional terms can be found in Part ID of the Permit. Stormwater discharges from construction activity require permit coverage, except for operations that result in the disturbance of less than one acre of total land area which are not part of a larger common plan of development or sale. A larger common plan of development or sale is a contiguous area where multiple separate and distinct construction activities may be tatting place at dierent times on different schedules under one plan. B. Types of Activities Covered This permit is intended to cover most new or existing discharges composed entirely of stormwaterfrom construction activities that are required by State regulation to obtain a permit. This includes stormwater discharges associated with areas that are dedicated to producing earthen materials, such as soils, sand, and gravel, for use at a single construction site. These areas may be located w the construction site or at some other location. This permit does not authorise the discharge of mine water or process water from such areas. This permit also includes stormwater discharges associated with dedicated asphalt plants and concrete plants located at the construction sites. C. Tiles of Activities NOT Covered This permit does not cover stormwater discharged from construction sites that is mixed with stormwater from other types of industrial activities, or process water of any kind. Other types of industrial activities that require stormwater discharge permits pursuant to different sections of the regulations (Regulation 5 CCR 1002-61, Section 61.2(e)(iii)(A-1, Kg, are not covered by this permit. This permit also does not cover the discharge of process water. If the construction activity encounters groundwater, a Construction Dewatering Discharge Permit (Permit Number COG -070000) must also be obtained in order to discharge this groundwater from the excavation site. An application for this permit can be obtained from the Division at the address listed in Part LA.4.a of the Permit. D. Exemptions for Small Municipalities The Intermodal Surface Transportation Efficiency Act of 1991 (Section 1068(c)) added an exemption to the stormwater regulations for municipalities with less than 100, 000 population. The term "municipality" includes cities, towns, counties, special districts or any entity created by or pursuant to State law. Stornnyater discharges associated with construction activity for facilities or sites that are owned or operated by a small municipality are not required to apply for or obtain a stormwater permit until March 10, 2003. (Note; This exemption does not apply to other, privately owned construction sites within the same small municipality.) COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division Rationale - Page 4. Permit No. COR -030000 IV COVERAGE UNDER THIS GENERAL PERMIT Under this general permit, operators of stormwater discharges associated with construction activity may be granted authorization to discharge stormwater into waters of the State of Colorado. This includes stormwater discharges associated with industrial activity from areas that are dedicated to producing earthen materials, such as soils, sand and gravel, for use at a single construction site, and dedicated asphalt plants and dedicated concrete plants. This permit does not pre-empt or supersede the authority of local agencies to prohibit, restrict or control discharges of storntwater to storm drain systems or other water courses within their jurisdiction. Authorization to discharge under the permit requires submittal of a completed application form and a certification that the SWMP is complete, unless the site is covered by a Qualifying Local Program. Upon receipt of all required information, the Division may allow or disallow coverage under the general permit. V. APPLICATION AND CERTIFICATION At least ten days prior to the commencement of construction activities (i.e.; the initial disturbance of soils associated with clearing, grading, excavation activities, installation of structural BMPS, or other activities), the operator of the construction site shall submit an original completed application which includes the signed certification that the SWMP is complete. In order to avoid confusion during processing, original signatures are required for the application to be considered complete. For small construction sires only, if the site is covered by a Oualifving Local Program (see below), submittal of an application is not required. For the purpose of this permit, the "operator" is the person who has day-to-day control over the project. This can be the owner, the developer, the general contractor or the agent of one of these parties, in some circumstances. At different runes of a construction project, different types of parties may satisfi> the definition of 'operator' and the certification may be rransfemed as roles change. (Note - Under the Federal regulations, this application process is referred to as a Notice of Intent, or NOI. For internal consistency with its current program, the Division will continue to use the term "application!) An outline of the permit application requirements is found in the permit at Part 1..A.4.b. If this general permit is applicable, then a certification will be developed and the applicant will be certified under this general permit. Vi. QUALIFYING LOCAL PROGRAMS For stormwater discharges associated with small construction activity (i.e., one to five acre sites), the permit includes conditions that incorporate approved qual'ing local erosion and sediment control program (Ottaliing Local Program) requirements by reference. A Qualifying Local Program is a municipal stormwater program for stormwater discharges associated with small construction activity that has been formally approved by the Division. The requirements for Qualfing Local Programs are outlined in Part 61.8(12) of the Colorado Discharger Permit System Regulations (also see the Division's "Oualing Local Programs for Small Construction Sites - Application Guidance ). Such programs must impose requirements to protect water quality that are at least as strict as those required in this permit. A. Approval Termination: A Qualifying Local Program may be terminated by either the Division or the rnunicipality. Upon termination of Division approval of a Qualifying Local Program, any small construction activity required to obtain permit coverage under Section 61.3(2)(h) of the State Discharge Permit System Regulations shall submit an application form as provided by the Division. with a certification that the Stormwater Management .Plan (SWMP) is complete as required by Parr 1.A.4 of the Permit, within 30 days. B Approval Expiration: Division approval of a Qualifying Local Program will expire with this general permit on June 30, 2007. Any municipality, desiring to continue Division approval of their program must reapply by March 31, 2007. The Division will determine if the program may continue as a approved Qual Eying Local Program. COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division Rationale - Page 5. Permit No. COR -030000 TERMS AND CONDITIONS OF PERMIT A. Coverage under a Ouali{vinuLocal Program — For Small Construction Sites Only For small construction sites (disturbing less than 5 acres) covered under a Qualing Local Program (see Section VI above), only certain permit requirements apply, as outlined below. The local program must have been formally designated by the Division to quay. Most municipalities have some type of local program and may require permits and fees. However, simply having a program in place does not necessarily mean that it is a qualifying program and that a State permit is not required. The local municipality will be responsible for notifying operators and/or owners that they are covered by a Oualifying Local Program. A list of municipalities with Qualifying Local Programs is also available at http://www.cdphe.state.co.us/wq/PermitsUnit/wgcdpmt.html. The Division reserves the right to require any owner or operator within the jurisdiction of a Qualifying Local Program covered under this permit to apply for and obtain coverage under the full requirements of this permit. Permit Coverage: If a construction site is within the jurisdiction of a Qualifying Local Program, the operator of the construction activity is authorized to discharge stormwater associated with small construction activity under this general permit without the submittal of an application to the Division. The permittee also is not required to submit an inactivation notice or payment of an annual fee to the Division. 2. Permit Terms and Conditions: The permittee covered by a Qualifying Local Program trust comply with the requirements of that Qualifying Local Program . In addition, the following permit sections are applicable: 1. 1.A.1, 1.4.2, and 1,4.3: Authorization to discharge and discussion of coverage under the permit. il. LC.1: General limitations that must be met in addition to local requirements. iii. L.C.2, LC.3: Prohibition of non-stormwater discharges unless addressed in a separate COPS permit, and requirements related to releases of reportable quantities. iv. LD: Additional definitions. v. Part 11 (except for Parts ILA. 1, I1.B.3, II.B.8, and 111'10): Specifically includes, but is not limited to, provisions applicable in the case of noncompliance with permit requirement, and requirements to provide information and access. B, Stormwater Management Plans (SWMPs) Prior to commencement of construction, a stormwater management plan (SWMP) shall be developed and implemented for each facility covered by this permit. A certification that the SWMP is complete must be submitted with the permit application. The SWMP shall ident)5' potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with construction activity front the facility. In addition, the plan shall describe the hest management practice (BMPs) which will be used to reduce the pollutants in stormwater discharges from the construction site. Facilities must implement the provisions of their SWMP as a condition of this permit. The SWMP shall include the following items: I. Site Description 2. Site Map 3. BMPs for Stormwater Pollution Prevention 4. Longterm Stormwater Management 5. Other Controls 6. Inspection and Maintenance 7. Signatory Requirements and Availability 8. SWMP Review/Changes (See Part I.B. of the permit for a more detailed description of SWMP requirements.) COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT Water Quality Control Division Rationale - Page 6. Permit No. COR -030000 /l. TERMS AND CONDITIONS OF PERMIT (cont.) C. Monitoring Sampling and testing of stormwater for specific parameters is not required on a routine basis under this permit. However. the Division reserves the right to require sampling and testing on a case-by-case basis, in the event that there is reason to suspect that compliance with the SWMP is a problem, or to measure the effectiveness of the BMPs ire removing pollutants in the effluent. D. Facility Inspections Active construction sites must inspect their- stornzwater management controls at least every i4 days and after any precipitation or snownrelt event that causes surface erosion. At sites where construction has been completed but a vegetative cover has nor been established, these inspections must occur at least once per month. At sites where winter conditions exist, inspections are not required during the period that the winter conditions exist. For all of these inspections, records must be kept on file. Refer to the pennit at Part 1. C.5 for detailed requirenzents of these inspections. E. Revision ofSWMP Based on the results of the uespections (see D. above), the description of potential pollutant sources and the pollution prevention and control measures, idennfeed in the SWMP, and the control measures themselves, shall be revised and modified as appropriate as soon as practicable after such inspection. Modification of control measures shall be implemented in a timely manner, but in no case more than 7 calendar days after the inspection. F. Reporting The inspection record shall be made available to the Division upon request. Regular submittal of an annual report is not required in this permit. O. Annual Fee The permittee is required to submit payment of an annual fee as set forth in the Water Quality Control Act. Pennittees will be billed for the initial permit fee within a few weeks of permit issuance and then annually, based on a July 1 through June 30 billing cycle. For small construction activities, if application was made for coverage with a completion date 12 months or less from the start of construction activity, a fee will be assessed based on the estimated number of calendar quarters the site is active. Projects going beyond that time will be billed the standard annual fee. H. Inactivation Notice When a site has been finally stabilized in accordance with the SWMP, the operator of the facility shall submit an Inactivation Notice that is signed in accordance with Part 1,E.] of the permit. The content of the Inactivation Notice is described in Part 1.A.6 of the permit. A copy of the Inactivation Notice form will be mailed to the permittee along with the permit certification. Additional copies are avatlablefr•om the Division. An exception to the requirement to submit an inactivation has been included in the renewed permit for Small Construction Sites that will be finally stabilized within 12 months of the beginning of construction activities. In such cases, the permit certification will indicate the automatic expiration date. If perrnit coverage is needed beyond that date, an extension request form must be submitted to the Division at least 10 days prior to the expiration date. COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division "ittonale - Page 7. Permit No. COR -030000 TERMS AND CONDITIONS OF PERMIT (cont.) 1. Transfer of Permit When responsibility for stormwater discharges at a construction site changes from one individual to another; the permit shall be transferred in accordance with Part I.A. 7 of the permit. The Notice of Transfer form will be mailed to the permittee along with the permit certification. Additional copies are available from the Division. lithe new responsible party will not complete the transfer form, the permit may be inactivated if the permittee has no legal responsibility, through ownership or contract, for the construction activities at the site. In this case, the new operator would be required to obtain permit coverage separately. J. Duration of Permit The general permit will expire on June 30, 2007. The permittee's authority to discharge under this permit is approved until the expiration date of the general permit. Any permittee desiring continued coverage under the general permit must apply for recertification under the general permit at least 90 days prior to its expiration date. Nathan Moore March 11, 2002 VII CHANGES MADE AFTER PUBLIC NOTICE Several comments were received from the Environmental Protection Agency (EPA). Changes based on these comments and additional internal re -view are discussed below: A. The EPA commented that language needs to be added to the permit addressing the certification requirements for inspection reports. Parr LE.1 of the Permit requires that all reports submitted ro the Division include specific certification language. Because site inspections required by Part I.C. 5 of the permit are not submitted to the Division, they are not covered under Part 1. C.5 of the Permit or Regulation 5 CCR 1002-61, Section 61.4(1)x, which require specific certification language. However, Regulation 5 CCR 1002-61, Section 61.8(4)(o)(ii)(B) does require that the permittee maintain a record summarizing the inspections that includes a certification that the site in compliance with the plan and the permit. Therefore, language has been added to Part LC.5 of the Permit, requiring that a .signed statement be included with all records of inspection on the status of compliance at the site. B. The EPA recommended that the Permit and Rationale be changed to indicate that the application is due ten days prior to the commencement of construction activities, instead of prior to the anticipated date of discharge. The Division agrees that this wording is preferable and more accurately indicates the Division's existing interpretation of the regulations. These changes have been made. C. The EPA expressed concern with requiring a permittee to transfer permit coverage in cases where the new responsible party may not be cooperative. Language has been added to the Permit and Rationale clarifying that termination of permit coverage is allowed when the permittee no longer has any legal responsibility through ownership or contract for the construction activity. D. The EPA commented on the lack of a definition for the terms "receiving water" and "ultimate receiving water ". A definition has been added to the Permit, and the term "ultimate receiving water" clarified to indicate that it means the first named receiving water, if the discharge initially goes to an unnamed ditch or storm sewer.

The site is approximately 4.5 miles south of Silt, CO. See the Figure 1 in Appendix A. The water storage facility will be constructed, operated, and reclaimed in three phases. These phases include: • Facility Construction (60 days) • Operation (20 years) • Reclamation (30 days) It is expected that the lifespan of the site will be approximately 20 years. EXISTING NETWORK This water storage facility will be accessed from CR 326. According to the guidelines in the Colorado Department of Transportation (CDOT) State Highway Access Code, this road is classified as a Rural Highway (R -B). CR 326 is a two lane asphalt roadway with gravel shoulders. The road has a posted speed limit of 35 mph. According to traffic counts (Garfield County 2002) the ADT for CR 326 is 150 vehicles per day (vpd). TRAFFIC PROJECTIONS Given the lack of data regarding traffic growth for this area, a conservative growth rate of 5% was assumed. This rate was applied to the existing counts to obtain background traffic for the forecast years of 2009 and 2029, respectively. These planning horizon years were chosen as they correspond with opening day of construction and reclamation, respectively. This results in an expected ADT of 211 vpd in 2009 and 560 vpd in 2029. Circle B #4 Water Storage Facility 1 January 30, 2009 Basic Traffic Analysis TRIP GENERATION/DISTRIBUTION Trip generation is generally determined using rates found in the ITE Trip Generation manual. Rates from this publication are applied to values related to the size of the proposed site to estimate the trips expected to enter and exit the site. In this case, no rates are provided for facilities similar to these. To estimate trips expected for this site, information was gathered regarding the expected traffic based on previous projects similar to this one. The following table summarizes the expected average and maximum trips for each phase discussed previously. Table 1: Trip Generation — Water Storage Facility Phase Average Trips/Day Maximum Trips/Day Percent Trucks Total Trips/Phase Phase Duration Construction 17 18 15 % 1002 60 days Operation 34 35 88 % 250280 20 years Reclamation 12 18 21 % 364 30 days Note that the estimated lifespan of the site is expected to be approximately 20 years. It should be noted that much of the truck traffic that is currently hauling water to and from BBC's operations in the area is already accounted for in the estimated current ADTs; therefore, the net increase in truck traffic during the operation of the facility is insignificant. Current ADT's and expected trip generation are shown in Figure 2 in Appendix B. Detailed tables showing daily trips for each phase are shown in Appendix C. CONSTRUCTION PHASE Staging areas and temporary access points will not be required during construction for this project, The access into this facility from CR 326 is already permitted by the Garfield County Road and Bridge Department; therefore, no additional permits are required. There will be no road closures or traffic interruptions. During the construction phase, it is not expected that a significant amount of the site traffic will be heavy truck traffic, 15% or less. This traffic will be primarily delivering and retrieving equipment on a 22 -wheel low boy truck or delivering equipment on 18 -wheel flat bed trucks. Circle B #4 Water Storage Facility 2 January 30, 2009 Basic Traffic Analysis AUXILIARY LANE ANALYSIS As defined by the Colorado State Access Code, CR 326 is classified as a Rural Highway (R -B). With this classification, auxiliary lanes are required for left turns greater than 10 vph and right turns greater than 25 vph in the peak hour. Given the volumes on CR 326, the addition of the small amount of traffic generated by the water storage facility does not bring turning volumes to the required amount for auxiliary lanes. EXISTING PARCELS Current land use on the parcel is primarily natural gas development with limited rural residential (one residence owned by BBC is located on the parcel) and agricultural use. The majority of existing traffic is related to natural gas development activities. One access exists and is permitted by Garfield County. No access to state highways or railroad crossings will be required. RECOMMENDATIONS Based on the expected trip generation rates discussed above, the increase in average daily traffic is not expected to be significant, particularly in light of the fact that the trucks that are estimated to be required to transport water to and from this facility are already servicing BBC's natural gas wells in the area. The worst-case scenario during operation of the facility is that there would be no net increase in truck traffic. Based on the results of the analysis, no mitigation is recommended for the water storage facility. As mentioned in the Auxiliary Lane Analysis, the addition of traffic by the site does not increase low existing volumes to levels required for auxiliary lanes.
