Bill Barrett has commissioned this Noise Impact Assessment to determine the environmenta l noise impact of the proposed facility . The results of this assessment will determine the potential compliance of the facility with the permissible noise level limits of the Colorado Oil & Gas Conservation Commission (COGCC). The assessment additionally provides the foundation to develop and evaluate noise control measures for the facility equipment should the results indicate that the facility exceeds the permissible noise level li mits of the Colorado Oil & Gas Conservation Commission (COGCC). Noise Solutions Inc. (NS I) was commissioned by Bill Barrett to complete this evaluation . Sound pressure levels for the significant noise sources associated with the proposed equipment were compiled from manufacturer's data, file data and theory. Using accepted acoustical engineering techniques, the sound pressure level data was used to calculate sound power levels. Sound power levels of the significant noise sources associated wi th proposed equipment were calculated from a combination of manufacturer's sound pressure level data, file data of previously measured units , and theory . The sound power levels were incorporated into ENM , an environmental noise propagation model. The noise propagation model was used to predict th e proposed facil ity sou nd levels at 6 reception points located 1909' northwest (residence 1 ), 2625' south-southeast (residence 2), 3005 ' north-northwest (residence 3 ), 3665' north-northeast (residence 3), 594' feet east (east property line), and 607' south (south property line) of the nearest noise source in accordance with the requirements of COGCC .

Table 1 Detailed Compressor Equipment Description Bill Barrett Circle B-6 Compressor Station Proposed Equipment Two compressor s powered by Waukesha L7044GSI Engines and cooled byAir-X-Chan gers 156EH Coolers NSI File #3636 1 Approach Sound pressure levels for the significant noise sources associated with the proposed equipment were compiled from manufacturer 's data, file data and theory . Using accepted acoustical engineering techniques , the sound pressure level data was used to calculate sound power levels. Sound power levels of the significant noise sources associated with proposed equipment were calc ulated from a combination of manufacturer's sound pressure level data, file data of previously measured units, and theory . Data regarding the topography and vegetation of the area surrounding the proposed facility site was noted during the site visit and supplemented with co mmercially available information . The data was inco rporated into ENM , an environmental noise propagation model. The noise propagation model was used to predict the proposed facility sound levels at 2 reception points located 594' feet east (east property line), and 607' south (south property line) of the nearest noise so urce in accordance with the requirements of COGCC. The direction chosen represents the most critical location as identified in a previous study commissioned by Bill Barrett . In addition, the facility, sound levels were predicted at four nearby residents located 1909' northwest (residence 1 ), 2625 ' south-southeast (residence 2). 3005' north- northwest (residence 3), 3665' north-northeast (residence(3}, lespectively. • The results of th e model are presented as the individual~~ponent sound levels as well as the overall existing and expanded facility sound level contributions for each reception location assessed. Sound level contours around the expanded facility were also generated . The results were reviewed and compared with the PNL 's of the COGCC Aesthetic and Noise Control Regulations 800 to determine the potential for compliance . Noise control measures. if warranted or requested , are develope d and evaluated within the noi se propagation model with the predicted sou nd level after im plementati on reported for each reception location assessed. 2 the sc ence of silence Criteria COGCC Aesthetic and Noise Control Regulations 800 is a location-oriented noise regulat ion that applies to energy industry facilities in the State of Colorado , USA. Noise levels from oil & gas facilities located on surfa ce property owned, leased , or otherwise controlled by the operator shall be measured at 350 feet from the noise source or at the property line, whichever is greater. Table 2 presents the Permissible Noise Levels (PNL's) for the reception lo cations assessed. The PNL's are based on the county zoning of Agricultural/Rural .

In response to this issue the COGCC outlines the methodology for the evaluation of facility related low frequency noise. The COGCC recommends that in situations where the complaint of Commission onsite inspection indicates that low frequen cy noise is a component of the problem, the Commission shall obtain a sound level measurement twenty-five (25) feet from the exterior wall of the residence or occupied structure nearest to the no ise source , using a noise meter calibrated to the dBC sca le. If this reading exceeds 65 dBC , the Commission shall require the operator to obtain a low frequency noise impact analysis by a qualified sound expert, including identification of any reasonable control measures available to mitigate such low frequency noise impact. Such study shall be provided to the Commission for consideration and possible action. NSI recommends using the 65 dBC Low Frequency Noise lim it as a facility design criteria when a re sidence is present because it is signifi cantly more efficient to treat low frequency noise at the design and const ru ction stages, rather than after the facility has been commissioned and is in operation. 3 lhe science of S• erice Sound Power Level Calculations Soun d powe r levels of th e proposed e quipmen t were ca lcula ted from a combinati on of so und pr essure leve ls of si mil ar operatin g eq u ipment a nd manufacture's sou nd level data.

The noise predi ction program completes complex sou nd propagation calculations that included the effects of the environment, terrain , and topography. The algorithms of the model a re based on methods and re sea rch we ll recognized in the acoustics commun ity and fo ll ow the CONCAWE algorithms. Acoustics Australia , an acoustics community publi cation has published two papers regarding algorithms and va li dation of the ENM software (Tonin 1985 , 1997). Noise Solutions Inc . has been involved with no is e impact assessments that have used the ENM software since 1998 . Over 1500 fa ci lities have been modeled using the ENM software since 1998 with the modelled results comparable to the measured results where data was available. The calcu lated source sound power levels , complete with information regarding the fa cility site equipment layout along with the reception locations , were entered into the model. The meteorologi cal conditions selected favoured the transmission of sound from the facil ity site to each point of reception , thus emulating a period during which the facility could experience no ise complaints.

Pre-application Summary Prepared by : Glenn Hartmann Senior Planner Date 4 Bill Barrett Corporation Compressor Booster Waiver Request Rural Zone District Section 4·203 F. Landscape Plan BBC requests a waiver for the Landscape Plan, Section 4·203(F) of the Garfield County Unified Land Use Resolution of2008, which requires planning, installment, and maintenance of landscaping for the proposed site. The site of the proposed compressor station will be located within the disturbed footprint ofa well pad permitted by COG CC. The location of the site is not in a high visibility area. The site location is remote and rural and the site will not be visible to the public. The Landscaping Plan is not applicable to the proposed site because the location has been previously developed and is located in non-populated area. Section 4·203 M. Water Management Plan BBC requests a waiver for the Water Management Plan, Section 4-203(M) of the Garfield County Unified Land Use Resolution of 2008. The proposed facility will not require water for personnel or operations. During operations, personnel will not be required to be manned at the site. Due to the minimal presence of employees onsite, water use will not be required onsite. During construction and operations, drinking water will be provided in the form of bottled water. A well will not be installed on site nor will irrigation be required for the proposed use. A portable toilet will be provide and maintained during construction. A waste hauler contract will provided at application submittal. Section 4·203 L. Traffic Study BBC requests a waiver for a traffic study. The proposed compressor booster will be unmanned and will not increase traffic during operations. Construction traffic is estimated to be minimal based on the construction schedule. A traffic study was conducted for the Bill Barrett Circle B Water Gathering Site located on the same parcel. Traffic for the proposed compressor station will use the existing access along Chipperfield Lane (CR 326) that is currently used for Circle B Water Gathering Site. BBC will provide the previous traffic study with a supplemental letter regarding traffic for the proposed site. ) Bill Barrett Corporation Circle B #6 Gas-Lift Compression Facility Circle B #6 Gas-Lift Compression Facility Bill Barrett Corporation Limited Impact Review Application Narrative Bill Barrett Corporation (BBC) is pursuing a Limited Impact Review (L!R) in Garfield County for the development of a compressor station, the Circle B Gas-Lift Compression Facility (CB#6GLCF). The proposed site will be located on private property, owned by Circle B Land Company LLC, approximately 5 miles south-southeast of Silt, Colorado. The site will be defined as a Compressor Station. The facility's main function will be to increase natural gas production on existing wells. 1.1 Description The purpose of the proposed CB#6GLCF site is to increase natural gas extraction from existing wells by facilitating the removal ofliquids (primarily water) from the well. The proposed compressor station will be constructed within the previously disturbed location of a COGCC permitted gas well pad. The wells on the adjacent CB #6 well pad will be one of three pads on the subject parcel that will be produced with the gas lift. The site is designed for two compressors to be installed and to be permitted with this application. Initially, BBC will only install one compressor. The second compressor will be installed at an undetermined date. Garfield County will be contacted before the second compressor is installed. The compressors will be powered by Waukesha L7044GSI Engines and cooled by Air-X-Changers 156EH Coolers. Gas lift is a form of artificial lift used in wells that have insufficient reservoir pressure to produce the well. The process involves compressing produced gas and injecting it through the tubing-casing annulus. Injected gas aerates the fluid in the tubing to reduce its density which then allows the formation pressure to lift the water column out of the well bore. After the downhole hydrostatic head has been reduced, the injection gas serves the purpose of maintaining critical rate; rate of flow required to carry produced fluids out of the well bore. Gas may be injected continuously or intermittently, depending on the producing characteristics of the well and the arrangement of the gas-lift equipment. The amount of gas to be injected to maximize production varies based on well conditions. Generally, the optimal amount of injected gas is determined by well tests where the rate of injection is varied and gas /liquid production is measured. The CB#6GLCF will not require personnel to be staffed at the site and personnel will only access the proposed site for maintenance. A copy of the Emergency Response Plan is provided in the Impact Analysis Tab. Certifications of training can be provided upon request. A conservation easement exists for the subject parcel. The Aspen Valley Land Trust (AVLT) has previously stated that the oil and gas rights are senior to the conservation easement and has waived rights to be a co-applicant for land-use applications. A letter from the AVLT to Garfield County regarding a previous application for a land-use permit on this property is provided in the Impact Analysis tab. BBC provided AVLT with the details of this application prior to submittal of the application to Garfield County. The site will be regulated by the COGCC's permissible noise levels. A Noise Analysis was conducted for the proposed site. The proposed site was designed to be within compliance of the COGOCC noise control regulations and several sound mitigation efforts for the site have been implemented. An insulated building will be installed over the compressors, engine silencers will be upgraded to a Application Narrative Garfield County Limited Impact Review, 2013 Page 1 of4 Bill Barrett Corporation Circle B #6 Gas-Lift Compression Facility Construction is estimated to take 6-8 weeks for grading and the installation of the equipment and facilities. All construction traffic will be confined to normal working hours with the possibility of occasional weekend work During the construction period, daily trips will average 29 vehicles per day. The grading of the site will require 2-3 tractor trailers to haul heavy equipment. The compressor and building will require 9 trips by tractor trailer and 2 gooseneck trailers to transport vessels and meters. 2 cranes will unload the compressor and 1 crane will remain onsite for 2 weeks to assist with building construction. An additional two weeks of clean-up, paint, and gravel spreading are estimated to follow once compressor construction is complete. During initial operations, 8-10 pickups will visit the site daily for the first 3 months of operation. In addition, there will be an occasional tractor trailer hauling in material and large equipment. After the initial operation phase, the facility will be unmanned and operations and maintenance activities will result in an average of 2 visits per day. The traffic study concluded that no axillary lanes would need to be installed for the development of the proposed site. The traffic for operational phase will not represent a significant increase over the light truck traffic that already exists servicing the various well pads in the area. A Traffic Memo and Traffic Analysis are located in the Impact Analysis tab. Bill Barrett Corporation (BBC) retained Noise Solutions, Inc. (NS!) to perform an analysis of the noise expected to be generated by the proposed compressor station and mitigation efforts that may be required so that the station will meet the applicable COGCC standards. Per COGCC Rule 802.c.(1 ), noise measurements shall be measured at 350 feet or the property line, whichever is greater. Therefore, NS! was asked to analyze the expected noise levels at the property lines closest to the proposed facility-594 feet east and 607 feet south. In addition, the expected noise levels at the four residences closest to the proposed facility were evaluated to ensure that noise levels at those residences would meet the applicable standards. For noise levels on the db(A) scale, the residential standard from COGCC Rule 802.c. was used as the applicable regulatory standard. For noise levels on the db(C) scale, the COGCC standard of 65 db(C) at the residences was used for this evaluation. Initially, NS! analyzed the noise level expected to result from this facility with no building over the compressors and also with a bare (uninsulated) building. Noise levels under these scenarios were predicted for each of the six receptor locations. Because the predicted noise levels exceeded the applicable standards, NS! then analyzed a series of mitigation measures that could be employed to meet the standards. These analyses are provided in Tables 12-17 in the report included in the Impact Analysis Tab. BBC will employ all of these mitigation measures at this facility. Tables 12-13 indicate that the db(A) noise levels at the property line would meet the COGCC residential standard, and Tables 14-17 indicate that the db(C) levels at each of the residences would meet the COGCC standard. The Noise Analysis is provided in the Impact Analysis tab. 1.2 Purpose and Need The proposed CB#6GLCF will result in improved efficiency in gas well production. The proposed gas lift facility on the Circle B property will accomplish this process on 21 wells spread across 3 pads. These wells historically yield high water volumes and require enhanced lift to clear fluids from the well bore. With reduced downhole pressure from the fluid being effectively removed, gas production rates will increase. The CB#6GLCF will be located within the footprint of the COGCC permitted well pad.

The site is located in a region with an annual precipitation of 11.58 inches. Three sediment basins exist adjacent to the site. Any accumulated sediment will be removed from the basins prior to construction of the compressor station. Site features are indicated in the grading plan located in the Erosion and Sediment tab. 2.14 Neighboring Areas. A description of neighboring areas with regard to land use and existing pertinent features such as lakes, streams, structures, roads, etc. Erosion and Sediment Narrative Garfield County Limited Impact Review, 2013 Page3of4 Bill Barrett Corporation Circle B #6 Gas-Lift Compression Facility The subject and adjacent parcels are zoned rural. According to the Garfield County Assessor's Office, surrounding land uses are listed as agricultural, single family residents. 2.15 Stormwater Management. A description of the stormwater management planning concept for the site, including both structural and nonstructural best management practices. The proposed site will be less than 1 acre in size and will not require a stormwater permit, however, best management practices consistent with those already in place for the existing well pad will continue to be employed 2.16 Stormwater Management Plan. Copy of the stormwater management plan application to CDPHE with date of submittal. The proposed site will be less than 1 acre in size and will not require a stormwater permit. While the proposed facility is not subject to CDPHE stormwater requirements, BBC will utilize stormwater BMPs consistent with those already implemented for the existing well pad. 2.17 Hydraulic Calculations. Hydrologic, hydraulic, and all other calculations used to size and design drainage facilities and/or structural BMPs. Hydrologic calculations will not change significantly. The sediment basins have been designed for the size and existing development based on the original SWMP. The existing sediment basins were installed and designed for the previously constructed well pad site, which was a 7.05 acre site. The compressor station site will be 0.654 acres and the basins are of sufficient size to accommodate the proposed site. 2.18 Maintenance Requirements. Maintenance requirements for all proposed BMPs should be discussed including access, schedules, costs, and designation of a responsible party. The maintenance requirements of the proposed BM P's shall be consistent with those of BBC's Stormwater Management Plan (SWMP) utilized for the adjacent well pad, even though a SWMP is not required. This applies to inspections and physical maintenance. Maintenance tasks may include sediment removal (when the BMP is at 50% capacity), reinstallation or removal and replacement of BMP's, installation of new BMP's, removal of unnecessary BMP's, or a combination of activities. A copy of the stormwater permit is located in the Maps and Plans tab.

Existing sediment basins and berms surround the site. The site was previously graded and designed to minimize any impacts. Hydrologic Features Figure is provided in the Impact Analysis Tab. The area consists of juniper woodland and sagebrush. Climate of the area is arid with an average annual precipitation of 11.58 inches according to the Western Regional Climate Center. Site photos are provided in the Impact Analysis Tab. 2.4 Soil Characteristics The CB#6GLCF is underlain by soils of the Ildefonso-stony loam, with 6 to 25 percent slope. The soils are deep, well drained, gently sloping to steep soils on mesas, alluvial fans, terraces and benches. 2.5 Geology and Hazard There are no landslides in the vicinity of the site and the hazard to landslides and rockfalls are low. The subject property and construction site are not within the extent of the Garfield County geologic study area. The slope figure is located under the Erosion and Sediment tab. 2.6 Groundwater and Aquifer Recharge Areas The 100-year floodplain boundaries are well outside the immediate vicinity of the CB#6GLCF as shown on Garfield County maps. Floodplain and flood fringe delineations are depicted in the Hydrologic Features Figure located in the Erosion and Sediment tab. The proposed site will be less than one (1) acre. CDPHE does not require a stormwater construction permit for sites less than one (1) acre. While the proposed facility is not subject to CDPHE stormwater requirements, BBC will utilize engineering and operational BMPs, consistent with those already implemented for the existing well pad, to limit runoff. 2. 7 Environmental Effects Determination of the existing environmental conditions on the parcel to be developed and the effects of development on those conditions, including: a. Determination of the long-term and short-term effect on flora and fauna; c. Determination of the effect on designated environmental resources, including critical Wildlife Habitat; 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; BBC contracted West Water Engineering Inc. (WWE) to prepare an Environmental Impact Assessment for the CB#6GLCF. The assessment determined the location of the gas-lift compression facility will not cause significant disturbance to flora or fauna. The proposed site location will be constructed on previously disturbed ground and is located within an area of similar development. The Environmental Impact Assessment, prepared by WWE, can be located in the Impact Analysis tab. Descriptions of existing flora and fauna habitat, wetlands and migration routes present in the vicinity of the project site can be found in the report. Impact Analysis Narrative Garfield County Limited Impact Land Use Application, 2013 Page 2 of4 Bill Barrett Corporation Circle B #6 Gas-Lift Compression Facility b. Determinatio n of the effect on significant archaeological, cultural, paleontological, and historic r eso urces BBC contracted Grand River Institute (GRI) Inc . to conduct a Class I cultural resource inventory for the proposed CB#6GLCF. The Class 1 Re search report is located in the Impact Analysi s Ta b . The purpose of the cultural resources investigation was to id e ntify previously recorded resources within or near the project area that may be a dversely affected by the propos ed action. No cultural res ources were recorded within the proposed construction area. Recommendations were that no further work is needed for the proposed project. Detail s on research findings, paleoclim a te, and assessment of cultural resources can be found in the report. e. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departm e nts; and No potentia l radiation hazard h as been id e ntified by the s tate or County Health De partment. f. Spill prevention co ntrol and co unter measures plan, if applicable. BBC's Picean ce Field Spill Prevention Control a nd Counter Me as ures Pl a n (SPCC) would be implemented during the construction and operation of the proposed s ite. 2,500 gallons of new oil and 1,000 gallons of used oil will be stored onsite. All tanks will have seco ndary containment sized to contain any leaks or spills. The locations of these tanks a re indicated on the Site Plan provided in th e Maps and Plans tab. 2 .8 Nuisance The traffic for operational phase will not represent a significant increase over the light truck traffic that a lready exists servicing the various well pads in the area. Construction is estimated to take 6-8 weeks for grading a nd the in s t a llation of the site. All construction traffic will be confined to normal working hours with the poss ibility of occasional weekend work. During the construction period, daily trips will a verage 29 vehicles per day. The grading of the site will require 2-3 tractor trailers to haul heavy equipment. The compressor and building will require 9 trips by tractor trailer and 2 goose n eck trailers to transport vessels and meters. 2 cranes will unloa d the compressor and 1 crane will remain onsite for 2 weeks to assist with building construction. An additional two weeks of clean-up, paint, and gravel s preading are estimated to follow once compress or construction is complete. During initial operations, 8-10 pi ckups wi ll visit the site daily for the first 3 months of operation. In a ddition, there will be an occasional tractor trailer hauling in material and large equipment. After the initia l operation phase, operations and m a intenance will result in an a verage of 2 visits per day. The traffic study concluded that no axillary lan es would need to be insta lled for the development of the proposed site. Traffic Memo and Traffic Analys is are lo cated in the Impact Analysis tab. Bill Barrett Corporation (BBC) retained Noi se Solutions, In c. (NS!) to pe rform an analysis of the noise expected to be generated by the proposed compressor station an d mitigation efforts that may be required so that the station will meet the applicable COGCC standards. Per COGCC Rule 802.c .(1), noise measurements s hall be m easured at 350 fe e t or the property line, whicheve r is greater. Therefo re, NSI was asked to analyze the expected noise levels at the property lines closest Imp act Analysi s Narrative Garfield County Limited Imp ac t Land Use Appli ca tion, 2013 Page 3 of 4 Bill Barrett Corporation Circle B #6 Gas-Lift Compression Facility to th e proposed faci lity -594 feet east and 607 feet south. In add ition, the expected noi se levels at the four r esiden ces closest to the proposed facility were evaluated to ensure that noi s e leve ls at those residences wo uld m eet th e a pplica bl e standards. For noise level s on the db(A) scale, th e residentia l s t a ndard from COGCC Rule 802 .c. was used as the applicable regulatory s tanda rd . For noise levels on the db(C) scale, the COG CC s tandard of 65 db(C) at the residences was u sed for thi s evaluation. Initia lly, NS! a n al yzed the noise level expected to result from this facility with no building over the compresso r s and also with a b a re (unins ulated) building. Nois e leve ls und e r th ese scenarios were predicte d for each of the six receptor locations. Because the predicte d noise levels exceeded the applicable s tandards, NS! th e n a nalyze d a se ries of mitiga tion measures that could be employ e d to meet th e standards. These a na lyses are provided in Ta bl es 1 2-1 7 in th e report included in th e Impact An a lys is Tab. BBC w ill employ all o f th ese mitiga tion meas ures a t this facility. Tabl es 12-13 indicate that the db(A) noise levels at the prope rty lin e would meet the COGCC residential standard, and Tabl es 14-17 indicate that the d b (C) level s at each of the residences would m eet the COGCC standard. The Noi se Analysis is provide d in the Impact Analysis tab. An a ir qua lity p ermit was iss u e d from t he Co lorado Departmen t of Publi c Health Environment (CDPHE) Air Pollution Control Divi s ion for the proposed s ite on April 18, 2 0 12.

Prepared for: Bill Barrett Corporation 112 Red Feather Trail Silt, CO 81652 Prepared by: Westwater Engineering, Inc. 2516 Foresight Circle #1 Grand Junction, Colorado 81505 November 2012 INTRODUCTION At the request of Bill Barrett Corporation (BBC), WestWater Engineering (West Water) biologists conducted assessments of wildlife, wild li fe habitats, and sensitive plant species for BBC's proposed compressor site on an existing well pad referred to as the C B6 PR Compressor (Cover Photo ; Figure 1 ). This document reports the results and analys is of the findings that are pertine nt to Garfield County Land Use regulations (2008) that apply to this project. The compressor site would be located on private lands approx imate ly 3.0 miles south of Silt, Colorado in SE if.i SE '/.i Section 35, Township 6 South, Range 92 West, 6 1h Principal Meridian. The elevation is approximate ly 6,020 feet. The site is accessed via Garfield County Road 326 (Chipperfield Lane) (Figure 1). SURVEY METHODS West Water biologis ts conducted surveys of the area on November 19, 20 12 to id entify and locate wildlife species, wildlife sign, vegetative communities, and wildlife habitats. A preliminary review of the project area using aerial photographs was conducted to familiarize biologists with the project area and as an aid to help determine the potential presence of wi ldli fe and any threatened, endangered, or sensitive plant and animal species. Data points collected during the survey were rec orded with handheld g lobal positioning system (GPS) receivers utili z ing the NAD83 map datum , with all coordinate locations based on the Universal Tran svers e M ercator (UTM) coordinate system in Zone 13 . Nest searches and bird identification were aided with the use of binoculars. Digital photographs were taken of the general project area. Raptor nest surveys were conducted using "walk-through methodology," a lso referred to as pedestrian surveys. Visual searches for raptor and other bird species' nests focused on suitable nesting habitat within a 0.25-mile radius of the project site. These surveys took place outside the active nesting season for raptors and migratory birds that inhabit the proj ect area. Biologists evaluated th e habitat conditions for threate ned , endangered, and sens itive plants within 100 meters of project features. Weed surveys were conducted within 30 meters of the project site . Vegetation types were detennined through field identification of plants, aerial photography, and on-the-ground assessments. SECTION 4-502 E. -ENVIRONMENTAL EFFECTS EXISTING ENVIRONMENTAL CONDITIONS Waters of the U.S. -Army Corps of Engineers WWE biologists determined that no wetlands or drainages showing characteristics of Waters of the U .S . wou ld be affected by the project. Vegetation Unaltered native vegetation near the s it e is consistent wit h juniper woodlands and sagebrush communities found throughout the region. Native plants that occur near th e site are presented in Table 1. WestWater Engineering Page 1 of IO November 2012 a e T bl 1 C ommon pi ant species o serve 1 b d h near t e site.

Serviceberry Amelanchier a/nifolia Smooth brome Bromus intermis Snowberry Symphoricarpos oreophilus Wild rose Rosa woods ii Wyoming big sagebrush Artemesia tridentata wyomingensis Yarrow Achillea millefolium Yellow rabbitbrush Chrvsothamnus nauseosus Threatened, Endangered, Sensitive Plant Species A review of the Colorado Rare Plant Field Guide (Spackman et al. 1997) indicated that no threatened, endangered, or sensitive plant species would be expected near the site based on soils, elevation, and distance to other known rare plant populations. Noxious Weeds Noxious weed surveys detected two State of Colorado or Garfield County listed noxious weed species (cheatgrass and Russian knapweed) within 30 meters of the project (Figure 1). Several nuisance plant species that are detrimental to revegetation efforts and of low value to wildlife were observed. These plants include kochia (Bassia scoparia), Russian thistle (Salsa/a tragus), and several additional annual weedy species. WILDLIFE Threatened & Endangered Wildlife No threatened, endangered, or candidate species of wildlife or suitable habitat for these species exists within the survey area. Colorado piekminnow (Ptychocheilus lucius ), razorback sucker (Xyrauchen texanus), bonytail chub (Gila elegans), and humpback chub (Gila cypha) and their respective designated critical habitats exist in the Colorado River downstream of the project. Rapt ors At a minimum, eleven raptor species have potential to inhabit the area surrounding the compressor and are listed in Table 2. The most common raptor species observed in the area include American Kestrel, Golden Eagle, and Red-tailed Hawk.

A large portion of the raptor survey area is composed of sagebrush shrub lands and agricultural lands with scattered juniper woodlands. Raptor nesting habitat in the juniper woodlands is poor quality, with few suitable nest trees. Migratory, Non-migratory, and Birds of Conservation Concern (other than raptors) WWE biologists conducted surveys and reviewed literature to determine the potential for bird species that could be affected by the project. Particular attention was given to identifying Bureau of Land Management (BLM) sensitive bird species (BLM 2009) and Birds of Conservation Concern (BBC). BCC have been identified for high conservation priority by the U.S. Fish and Wildlife Service (USFWS) (USFWS 2008) to prevent the listing of additional species under the Endangered Species Act by implementing proactive management and conservation actions.

The area directly affected by the project has previously been disturbed and provides no nesting habitat. American Elk and Mule Deer The site is located in Colorado Parks and Wildlife (CPW) Game Management Unit (GMU) 42. The proposed compressor site is within CPW's Natural Diversity Information Source (NDIS) mapped mule deer winter concentration area, mule deer severe winter range, and an elk winter concentration area (Figures 3 & 4) (NDIS 2012). The habitat surrounding the project is important for wintering elk and mule deer and both species were documented on the site. Black Bear and Mountain Lion CPW-NDIS mapping shows the site to be within overall range for black bear and mountain lion, but not within a human conflict area with either species (NDIS 2012). Both species could be expected within the general area year-round, though black bear typically hibernate from mid- November through May. Small Mammals Common small mammal species in the project area include coyote (Canis latrans), cottontail (Sylvi/agus spp.), least chipmunk (Tamias minimus), and a multitude of additional rodent species. Reptiles Western terrestrial garter snakes (Thamnophis elegans) and racer (Coluber constrictor) would be the most common snakes expected in the vicinity (Hammerson 1999). Several lizard species could inhabit the area. Amphibians Since there are no permanent water sources near the site, no amphibian species are expected to occupy the area and none would be potentially affected. SECTION 4-502 (8) (a) Determination of Long and Short-term Effects on Flora and Fauna FAUNA Threatened & Endangered Wildlife Endangered fish are unlikely to be affected by this project due to distance from the project, the unlikelihood of water contamination from the project, and the current storm water and runoff controls already in place for the existing well pad and access road. No other threatened or endangered species occur in or near the project area. Rapt ors No raptor nesting habitat would be directly affected and no nests are known to exist within 0.25 miles of the project. The possibility for effects related to construction, operation, and maintenance of the compressor in the midst of other activities in the area is low. Westwater Engineering Page 4of10 November 2012 American Elk and Mule Deer Human presence and activity can be expected to affect distribution of individuals and also may result in temporal effects on habitat use. The area affected by the project has previously been cleared of native vegetation and the loss of forage due to the project would be minimal. Black Bear and Mountain Lion Potential encounters of black bear with personnel could occur if garbage or food is not disposed of properly. Incidences of human-black bear interactions sometimes result in the euthanasia of offending bears by the CPW. Mountain lions would not be affected. Birds, Small Mammals, and Reptiles No nesting habitat would be affected by the project. Human presence and activity may affect animal distribution. The effects of this project are expected to be negligible for these species. FLORA No native vegetation would be affected for the development of the compressor site. No threatened, endangered, or other special status plants would be affected. It appears that the current noxious weed management strategy is moderately effective. SECTION 4-502 (8) (c) (1) Determination of the effect on significant environmental resources--critical wildlife habitat Potential issues are outlined below. • Big Game Winter Range and Migration Corridors: The compressor site is situated within deer and elk winter ranges including a deer winter concentration area, deer severe winter range, and an elk winter concentration area. Vegetation on the site was previously removed for development of the Circle B #6 well pad and no significant additional forage loss is expected. No specific deer or elk migration corridors are affected, though migration occurs in and around the site. • Indirect Construction Effects: Additional human presence and activity related to construction, operation, and maintenance of the compressor may influence spatial and temporal use of habitat surrounding the project by wildlife. Since the site exists amid significant human presence related to other activities in the area, the additional disturbance from this project is expected to be low, but does contribute to the cumulative effect of development in the area.

The s ite is located on private lands south of Silt, CO in SE \14 SE \14 Section 35, Township 6 South, Range 92 West, 61h Principal Meridian . The elevation is approxi mate ly 6,020 feet. The site is accessed via Ga rfi eld County Road 326 (Chipperfield Lane) (Figure I). T he cu1Tent prima1y land uses of the area include live stock graz in g, hay production, wi ldli fe habitat , and natural resource extraction including natural gas development. 1.2 General Survey Information Vegetation types were determined through field identification of plants , aerial photography , and on-the- gro und assessments. Identifi cation of pl an t species was aided by using pertinent published field guides (Wh itson et al. 200 I , CWMA 2007, Kershaw et a l. 1998, Weber an d Wittmann 200 I). Mapped soil types, as published by the Natural Resources Conserva ti on Service (NRCS), U.S. Depa11ment of Agricu lture (USDA), were reviewed to dete1mine the soi l types an d expected natural vegetation characteristic s at the project site (NRCS 2012). Field inspections were conducted on November 19, 2012 . Locations of weeds and other features included in this report were recorded with the aid of a handheld global positioning sys tem (GPS) receiver using NAD83 map datum , with all coordinate locations based on the Un iv ersa l Transverse Mercator (UTM) coord in ate sys tem in UTM Zone 13. Photographs were taken of the general project location , vegetation, terrain , and specific weed findings . 2.0 LANDSCAPE SETTING 2.l Vegetation and Climate Th e project would take place within an existing disturbance resulting from the presence of a natural gas well pad (Circle B #6). The existing vegetation immediately surrounding the project site consists of sagebru sh slu·ublands and juniper dominated woodlands. Common plant spec ies observed in the area are shown in Table 1.

Most h ave come from Europe or Asia, e ither accidenta ll y or as orn amenta ls that have escap ed. Once established in a n ew e nvironment, they t end to spread quickl y because th e insects, di seases, and anima ls that nonnally control them are absent. Noxious weeds a re spread by ma n, a n imals , water, and wind. Prime locations for the establi s hme nt o f noxious weeds include roadsides, cons truc ti o n si tes, areas that are overused by anima ls or humans, wetlands, and ripari an corridors. Subsequent to soil disturbances, vegetation communities can be s usc ep tible to infe stati o ns of invasive or exotic weed species. Vegetation remova l a nd soi l disturbance during construction can creat e optimal conditi ons for th e es tabli shme nt of invasive, non-native species. Constru c tion equipment traveling from weed-infested areas into weed-free areas could disperse noxi ous or invasive weed seeds a nd propaga tes, resu lting in th e estab li shment of these weeds in previo u sly weed-free areas. WestWater Engineering Page 2 of8 Nove mber 2012 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 Garfield County Weed Advisory Board has compiled a list of 21 plants from the State list considered to be noxious weeds within the county (see Appendix A). The Garfield County Weed Advisory Board has duties to: I. Develop a noxious weed list, 2. Develop a weed management plan for designated noxious weeds, and 3. Recommend to the Board of County Commissioners that identified landowners submit an integrated weed management plan for their properties. 3.2 Noxious Weed Occurrences No noxious weeds were located within the project footprint which occurs within an existing disturbance. Russian knapweed (Acroptilon repens) is a State of Colorado "B List" and Garfield County listed weed and approximately 100 plants were observed near the project site. Cheatgrass (Anisantha tectorum) (State of Colorado "C List" species) was present within 100 feet of the site. In areas where soil disturbances have created growing conditions that favor non-native vegetation, several nuisance weed species are present. These plants can negate revegetation efforts and cause losses due to decreased seeding success and associated costs. The presence of these plants creates increased competition for resources and can negatively affect desirable native plant species. Plants in this category observed in the project area include kochia (Bassia scoparia), Russian thistle (Sa/sofa spp.}, and various annual mustards. These nuisance weeds occur on disturbed soils near the project. 3.3 Integrated Weed Management Control of invasive species is a difficult task and requires intensive on-going control measures. Care must be taken to prevent damage to desirable plant species during treatments to prevent further infestations by other pioneer invaders. Weed management is best achieved through a variety of methods over a long period of time including inventory (surveys}, direct treatments, prevention through best management practices, monitoring of treatment efficacy, and subsequent detection efforts. Weed management is often reserved to "control" of existing species and prevention of further infestations (existing and new species) rather than eradication. After successful and effective management, decreases in infestation size and density can be expected, and after several years of successful management practices, eradication is sometimes possible. 3.4 Prevention and Assessment of Noxious Weed Infestations Weed management is costly and heavy infestations may exceed the economic threshold for practical treatment. Prevention is especially valuable in the case of noxious weed management. Several simple practices should be employed to prevent most weed infestations. The following practices should be adopted for any activity to reduce the costs of noxious weed control through prevention. The practices include: • Prior to delivery to the site, equipment should be thoroughly cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds. • If working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris at the infested area prior to moving to uncontaminated terrain. WestWater Engineering Page3of8 November 2012 • All maintenance vehicles should be regularly cleaned of soil. • Avoid driving vehicles through areas where weed infestations exist. Assessment of the existence and extent of noxious weeds for an area is essential for the development of an integrated weed management plan. This report provides an initial assessment of the occurrence of noxious weeds for the project area. In order to continue effective management of noxious weeds, further inventory and analysis is necessary to I) determine the effectiveness of the past treatment strategies; 2) modify the treatment plan, if necessary; and 3) detect new infestations early, which would result in more economical treatments. 3.5 Treatment and Control of Noxious Weed Infestations Recommendations for control of listed noxious weed species found in the project area are described in Table 3. For specific herbicide recommendations, consultation with a licensed weed control contractor is recommended. Table 3. Control methods for noxious weeds observed in project area Common Name USDA Scientific name Symbol Type Control Methods Herbicide treatment including pre-and post-emergent Cheat grass BRTE Annual treatments, tillage, and reseeding with native cool-season Anisantha tectorum grasses.

Reseed with competitive native grasses. 3.6 General Recommended Treatment Strategies The following general treatment strategies are presented for reference. It is important to know whether the target is an annual, biennial, or perennial to select strategies that effectively control and eliminate the target. Treatment strategies vary depending on plant type, which are summarized in Tables 4 and 5. Herbicides should not always be the first treatment of choice when other methods can be effectively employed. Table 4. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. develop, cut and bag seed heads. 2. Cut roots with a spade just below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. If seeds 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering, but can reduce total seed production. (Sirota 2004) Table 5. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring, but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. WestWater Engineering Page 4 of8 November 2012 Table 5. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 2. Herbicide treatment at bud to bloom stage or in the fall (recommended after August 15 when natural precipitation is present). In the fall, plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3. Mowing usually is not recommended because the plants will flower anyway; seed production should be reduced. Many studies have shown that mowing perennials and spraying the re-growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its basic biology. Timing of application must be done when biologically appropriate, which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only Y, in. - 1 in. long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. (Sirota 2004) Some weeds, particularly annuals and biennials, can develop resistance to herbicides. The ability to quickly develop immunity to herbicides, especially when they are used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration according to the product label. Most misuse is centered on excessive application, either in frequency or concentration. This results in mostly top kill and resistant phenotypes. 3.7 Best Management Practices -Noxious Weeds Construction: The following practices should be adopted for any construction project to reduce the costs of noxious weed control and aid in prevention efforts. 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; WestWater Engineering Page 5 of8 November 2012 • 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. In areas with slope greater than three percent, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When utilizing hydro- seeding followed by mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. Herbicides: Many of the listed noxious weed species in Colorado are susceptible to commercially available herbicides. Annual and biennial weeds are best controlled at the pre-bud stage after germination or in the spring of the second year. Selective herbicides are recommended to minimize damage to desirable grass species. Professionals or landowners using herbicides must use the concentration specified on the label of the container in hand. Herbicides generally do not work better at higher concentrations. Most herbicide failures observed by WestWater are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient translocation process. Most herbicide applications should use a surfactant, if directed on the herbicide label, or other adjuvant as called for on the herbicide label. Grazing: In the event grazing is allowed in the project area, it should be deferred in reclaimed areas until the desired plant species that have been seeded are established. Alternative Methods: An alternative method, particularly where there is poor or destroyed topsoil, is the application ofvesicular-arbuscular mycorrhizal fungi, typically referred to as AMF. These fungi, mostly of the genus G/omus, are symbiotic with about 80 percent of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful when reclaiming this project. In symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as much as several orders of magnitude (Barrow and Mccaslin 1995). Over-the-counter commercial products, which are better adapted to coating seeds when re-seeding and treating roots of live seedling trees and shrubs at time of planting, come in powder form and are available from many different sources. Some also come in granular form to be spread with seed from a broadcast spreader. The best AMF products should contain more than one fungi species. All Colorado State Forest Salida District tree and shrub plantings include the application of AMF (Tischler 2006). Most, if not all, Colorado Department of Transportation re-vegetation/reseeding projects now require use of AMF and BioSol, a certified by-product of the penicillin manufacturing process composed primarily ofmycelium. Compacted soils respond well to fossilized humic substances and by- products called humates. These humates, including humic and fulvic acids and humin were formed from pre-historic plant and animal deposits and work especially well on compacted soils when applied as directed. 3.8 Commercial Applicator Recommendations A certified commercial applicator is a good choice for herbicide control efforts. Restricted herbicides require a Colorado licensed applicator. An applicator has the full range of knowledge, skills, equipment, and experience desired when dealing with tough noxious weeds. Reclamation farming services using multiple seed bin range drills and specialized related equipment is available and should be used for reclamation seeding projects. WestWater Engineering Page 6 of8 November 2012 Monitoring: Areas where noxious weed infestations are identified and treated should be inspected over time to ensure that control methods are working to reduce and suppress the identified infestation. The sites should be monitored until the infestations are eliminated or reduced to acceptable levels. These inspections can then be used to prioritize future weed control efforts. 4.0 REVEGETATION -RECLAMATION Site-specific reclamation plans should be developed with a qualified reclamation contractor. Successful reclamation of the project area is dependent upon soil type and texture, slope gradient and aspect, proper weed control, available water, and revegetation with suitable plant species.

The project is located east of Hunter Mesa, between Dry Hollow Creek and Divide Creek, and it is approximately 9 miles east-southeast of the town of Rifle in Garfield County, Colorado. A seven acre area of private land with existing disturbance was inventoried at a Class I level. This work was undertaken to ensure the project's compliance with county regulations governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. This work was performed under Bureau of Land Management (BLM) Antiquities Permit No. C-52775. The purpose of this cultural resources investigation was to identify previously recorded resources within or near the project area that may be adversely affected by the proposed action. The Class I files search and report preparation were performed on the l 5'h and 16 1 " of November 2012. As a result, no cultural resources were found to have been previously recorded within the proposed construction area which is to be contained within a previously disturbed area (totaling approximately 7.05 acres). Five inventories and three cultural resources (5GF.239, 5GF.261, and 5GF.304) were identified outside of the project area during the files search. Two of the inventories and two cultural resources (5GF.261 and 5GF.304) occur within a one mile radius of the proposed project area. The nearest cultural resource is site 5GF.261, a prehistoric open camp which is located approximately 530 meters to the west-southwest. Accordingly, this project will have no effect on eligible or potentially eligible cultural resources as known resources are located outside of the area of proposed impact. 11 TABLE OF CONTENTS Introduction ............................................................. .

The project is located east of Hunter Mesa, between Dry Hollow Creek and Divide Creek, and it is approximately 9 miles east-southeast of the town of Rifle in Garfield County, Colorado. A seven acre area of private land with existing disturbance was inventoried at a Class l level. This work was perfonned under BLM Antiquities Permit No. C-52775. This work was undertaken to ensure the project's compliance with county regulations governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. The purpose of this cultural and paleontological resources investigation was to identify previously recorded resources within or near the project area that may be adversely affected by the proposed action. 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 project is located cast of Hunter Mesa, between Dry Hollow Creek and Divide Creek, and it is approximately 9 miles east-southeast of the town of Rifle in Garfield County, Colorado. It is located on private land in T.6S., R.92W., Section 35; 61 " P.M. (Figure l ). Environment The project area is located within a large northwest-southeast trending structural downwarp known as the Piceance Creek Basin, a major geological subdivision of Colorado. 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 l 977: 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. Landslide Deposits, Older Gravels and Alluviums, and the Wasatch Formation occur in the general area; the proposed project area is underlain by Broadway and Louviers Alluviums of the Pinedale and Bull Lake Age Gravels and Alluviums. Elevation of the project is approximately 6000 feet, which falls within the Upper Sonoran Zone.

Other species present are galleta, Indian ricegrass, needle- and-thread grass, gilia, larkspur, and wild four o'clock. These communities support a variety of wildlife species although the present day land use of the project area (including energy development, grazing, ranching and fmming) has pushed most large mammals into the sun-ounding mountains. There, mule deer, elk, coyote, and black bear are common, as are cottontail rabbits, beavers, 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, and various raptors. Present land use includes energy development, open range for domestic animals, and modern hunting. Climatically, these relatively low elevations are host to a cool semiarid climate where temperatures can drop to -I 0 degrees F during the winters and summer temperatures may reach 100 degrees F; there is a maximum of 140 frost free days and the annual precipitation is about I 0 inches. The surrounding higher elevations arc characterized as cooler and moister. Annually, the high mountain temperatures could average 5 degrees cooler and the precipitation as much as 14 inches greater that the su1rntmding low elevations (USDA SCS 1978:244). 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 the surrounding area. Generally, only gross climatic trends have been established for western North America prior to 2000 BP (Antevs 1955; Beny and Beny 1986; Madsen 1982; Meln·inger 1967; Peterson 1981; Wendlund and Bryson 1974). 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 ofresolution (Dean et al. 1985). Cultural Background Cultural resources 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 regional occupation during the Paleoindian, Archaic, Formative, and Protohistoric Eras. Historic 3 records indicate 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 Northern Colorado River Basin" (Reed and Metcalf 1999), and "Colorado History: A Context for Historical Archaeology" (Church et al. 2007). Region Cultural Assessment Previous archaeological studies in the general vicinity have suggested regional occupation for as long as 8000 years, although recently an inventory of block units east of this study area within the Doghead GAP (Conner et al. 2006) provided direct evidence of the presence of Foothill-Mountain Paleoindian occupation at 5GF1323, which pushes the regional prehistoric occupation dates back to about 10,000 yr BP. Historic records also indicate a permanent Euro-American presence in the region began as early as the late l 880's. Notably, the prehistoric sites in the river corridor have been impacted by the 130 year occupation and use of the area by EuroAmericans. Many of the newly and previously recorded resources in the general area indicate it was intensively occupied during the Protohistoric Era. Unfortunately many of the sites where wickiups were present, post-cutting and wood collection by the Historic EuroAmerican settlers and ranchers over the past 125 years has nearly wiped out evidence of their presence. Also, surface collection of diagnostic artifacts has impacted the sites and affected the assignment of cultural/temporal associations. In general, although the study area was probably not continuously occupied prehistorically, it seems to have offered an attractive environment for gathering, floral processing, hunting, as well as lithic procurement and processing. Site density in the surrounding mesa areas is high, probably due to two factors: good access to permanent water, and strategic topographical positioning on the ridge tops and open benches. Such camp placement provided a good view of the surrounding lower elevations for purposes of hunting and protection. The heavily vegetated canyon bottoms were accessed for reasons of acquiring water and for the procurement of floral and fauna! resources. The apparent differences in the characteristics of the upland and lowland sites may be due to factors other than cultural selection. The lowland sites are subjected to more artifact collecting than the uplands, and the areas along the Colorado River have been subject to few cultural resource surveys. The upland area exhibits a very thick vegetation cover that may be limiting discovery offeatures and additional artifacts. Lowland sites exhibit greater variability in site types. While the uplands are limited to isolated finds, open camps, and lithic scatters; the lowlands contain these site types and open architectural sites, sheltered sites, and a single tool stone procurement area. The lowland sites contain higher frequencies of cultural features or evidence of features. These features include fire-cracked rock scatters, charcoal stains, hearths, stone structures, and wickiups. All of the prehistoric sites contain low numbers of artifacts, including very limited numbers of debitage, 4 bi facial tools and expedient tools. This suggests conservation, curation, and reuse of flaked stone tools in an area where tool material sources are limited. Lowland sites tend to be situated in the pinyon-juniper vegetation community in greater frequencies than is suggested by the relative proportion of the pinyon-juniper to other vegetation communities. The sites in the uplands are distributed proportionally to the size of the vegetation communities, with the mountain shrub and sagebrush communities exhibiting the highest site density. Too little is known of the age of the sites to make any definitive statements. The distribution of site ages based on projectile points and ceramics is generally the same as portrayed in Reed and Metcalf(1999), but the lack of absolute dating precludes any conclusions in this area. Lithic scatters exhibit a smaller site size than open camps in both the lowland and upland settings. Isolated finds are distributed across a wider range of slopes than lithic scatters or open camps. The differences in the type and distribution of historic sites are: Sites in the uplands are limited to sheep and cattle raising activities and are primarily post-I 889. Sites in the uplands are distributed proportionally to the size of the vegetation communities, with the mountain shrub and sagebrush communities exhibiting the highest site density. Sites in the lowlands display a greater diversity in types and are found mainly in the pinyon-juniper and sagebrush zones. The historic sites in the lowlands are concentrated near transportation corridors and near permanent water sources, patiicularly the habitation sites. Sites indicative of particular economic activities are spread across the landscape. During 1980, the BLM 's Glenwood Springs Resource Area was subject to an archaeological survey that randomly sampled three percent of its managed lands. A total of J 7,400 acres was surveyed for cultural resources. As a result, 58 prehistoric sites and 2 historic sites were recorded, an average of about 2 sites per section (.0034/acre ). Three types of prehistoric sites were distinguished by the study; limited activity areas, short-term camps, and large habitation sites. These were classified on the basis of site size and the diversity of artifacts/activities represented. Notably, the sites were unevenly distributed and varied by vegetation community. The highest site density, about 5.0 sites/section (.0078/acre), occurred in pinyon/juniper and sagebrush communities. Concurrently, the greatest number of sites located during the survey tended to occur in or near the pinyon/juniper community. Other environmental factors found to be important during the statistical analysis of the settlement patterns included 1) vertical distance between the site and the primary water source is a greater controlling factor that the horizontal distance, 2) sites tend to be near or on points of vantage, 3) sites tend to be located in forested areas, preferably with a southern exposure and, 4) sites tend to occur on flat ground (less than 40% grade) in areas of relatively low surface relief (Burgess et al. 1980: J 08-120, J 38-J 39). In general, the region exhibits a relatively low site density and sites tend to cluster near permanent water sources. 5 Relevant Historical Background post-1880 The Ute people occupied large areas of Western Colorado until about 1881. Due to the White River Ute's discontent that lead to the "Meeker Massacre," as the incident became known, a congressional investigation lead to the Treaty of 1880 that stipulated the removal of the White River bands to the Uintah Reservation in northeastern Utah. The Uncompahgre band was to be given a small reservation in the vicinity of the confluence of the Colorado and Gunnison Rivers. Aware of the value of these agricultural lands, however, the commission charged with enforcing the terms of the treaty, under the direction of Otto Mears, manipulated the location process using a loophole in the treaty language, and the Uncompahgres were given lands in Utah near the Uintah Reservation. The Southern Ute bands were left on the small reservation in southwestern Colorado that had been given them by the Treaty of 1873. On l September 1881, the last of the Utes were moved to their new reservations in Utah, and western Colorado was completely opened to the whites. Interest in the potential agricultural lands of western Colorado (namely the Uncompahgre, Gunnison, Colorado, Dolores, San Miguel, White, and La Plata River valleys) had been growing for some time prior to the Utes' banishment, and by the spring of 188 I frontier towns closest to the Ute lands were "crowded with people, anxious to enter the Reservation and take possession of the most desirable locations (Haskell 1886:2)." Only days after the last of the Utes had been expelled, settlers began rushing onto the reservation lands. Settlement activity spread quickly--during the autumn months of 1881 land claims were staked, townsites were chosen, and railroad routes were surveyed (Haskell I 886, Borland 1952. Rait 1932). However, because the former reservation lands were not officially declared public lands until August 1882, the first year of settlement activity was marked by a degree of uncertainty regarding the legality of land claims. When finally announced, the 1882 declaration did not allow home-stead entries on the newly opened lands, but only pre- emptions, or cash entries, at the rate of$ I .25 per acre for agricultural land, $5.00 per acre for mineral land (Borland 1952:75). By 1895, the major portion of the land along Mamm Creek had been claimed, mostly under Cash Entry patents. The settlers raised their own food and availed themselves of the plentiful game in the area. Gardens, hay fields, and orchards were planted, and irrigation ditches were dug to dive11 the creek's water to cultivated fields. Large herds of cattle and sheep were accumulating, grazing the valley floor and the vast open range above, driven to the uplands via trails leading up the various gulches. Because the area was still fairly remote, competition for lands had not yet begun. Travel in and out of the Rifle area was restricted to horse and/or wagon. There were several well-developed Ute trails, and in the early 1880s, the federal government had built the aforementioned road between the White and Grand Valleys. In 1885 a toll road opened along the Grand River between Rifle and Grand Junction; prior to the building of this road through DeBeque Canyon, the route to Grand Junction had been a two-week journey "through the 6 Cedar Hills, up Kimball Creek ... down the "Sawtooth Range to Fruita and then back to Grand Junction" (Murray 1973:5). But, despite this network of trails and roads, Parachute remained pretty much isolated. With the coming of the D&RG railroad in 1890, however, new pressures were brought to the area. More and more settlers arrived, competing not only for arable land but also for grazing privileges on the unpatented public domain of the surrounding uplands. Increasing numbers of cattle and sheep were imported, some being rnn as commission cattle for outside investors (ibid:84). Open warfare between cattle and sheep ranchers ensued, resulting in the slaughter of thousands of animals. Four thousand sheep belonging to Messrs. Starkey and Charlie Brown were killed by masked men who tried to drive the animals over cliffs at the head of a Clear Creek tributary and above the Granlee Schoolhouse (LaPoint et al. 1981 :3-5 I). Another 4000 sheep belonging to J.B. Hurlburt were driven to their deaths above Ben Good Creek, a tributary of East Fork. The animosity between cattlemen and sheepmen continued into the 1900s. Finally, Congress passed the Taylor Grazing Act in I 934, bringing to an end to the free range by providing for regulated grazing and an end to the Sheep-Cattle Wars. Cash Entry, Desert Land, and Homestead patents continued to be granted into the 1920s and 30s. Ranching and farming were still the most important economic activities in the Parachute area and remained so until the 1960s and 1970s when many of the farms and ranches of the region were bought up by large companies interested in the large-scale extraction of oil shale and natural gas. Files Search Results A files search for knm\11 cultural resources and inventories within the project area was made through the Colorado Historical Society's Office of Archaeology and Historic Preservation. The search revealed that no cultural resources or inventories have been identified or conducted within the project area. However, within approximately one mile of the project area, three cultural resources (5GF.239, 5GF.261, and 5GF.304) have been recorded and five inventories have been conducted (Tables I and 2). The nearest cultural resource is site 5GF.26 l, a prehistoric open camp which is located approximately 530 meters to the west-southwest. The site is field evaluated as needs data (potentially eligible). Site 5GF.239 is a historic dugout and it is also field evaluated as needs data. The third site (5GF.304) is a prehistoric rock art site and, accordingly, it is field evaluated as eligible. A search of the 1888 survey plat (Document No. 178370) from the Bureau of Land Management General Land Office records for the subject area yielded no likely locations for additional cultural resources. 7 Table 1.

The nearest cultural resource is site 5GF.261, a prehistoric open camp which is located approximately 530 meters to the west-southwest. Five inventories have been conducted within approximately one mile of the project area. Accordingly, this project will have no effect on eligible or potentially eligible cultural resources as known resources are located outside of the area of proposed impact.

IO RECLAMATION PLAN Upon completion of construction , any areas not needed for the continued operation of the communications facility will be recontoured to match the pre-disturbance contours as closely as possible and the area will be reseeded . For best results and success , the recommended grass mixture reseeding (see table below) will be done in late autumn immediately following completion of construction . Preferred seeding method will consist of hand raking and broadcast seeding followed by hand raking at a 90 degree angle to the first raking . Because of the relative flatness of the slopes, mul ching is not anticipated. If necessary, a second seeding will take place in the fall of each year following construction.

Given the la ck of data regard ing traffic growth for this area, a conservative growth rate of 3% was used . T hi s rate was applied to the existing cou nts t o obtain background traffic for th e horizon years of 2013, 2043, and 2044. These horizon years were chosen as they correspond with opening day of construction, the end of operation, a nd reclamation, respectively. These result in expected ADTs shown below in Table 2 . It is assumed that the design hourly volume is 10% of the average daily traffic.

During these 30 years, approximately the first 6-8 weeks, during construction, and the last 6-8 weeks during reclamation , will have higher amounts of average daily traffic. The average trips per day over the entire construction period are approximate ly 29 vpd (PCE). It is expected that during the peak hour, 10% of the average trips w ill visit the site. It is expected that 80% of the site traffic will travel to and from Silt on CR 331 via CR 346 and the remaining 20% will use CR 331 via CR 336 and CR 315 . CR 326 and CR 331 meet approx imately 1.4 miles northwest of the project site . Site traffic will access the site via CR 326 . T RAFFIC VOLUM E INCREASE The distribution of site-generated trips was assumed to have all trips entering from the Interstate 70 & CR 315 interchange . As previous ly stated, traffic vo lumes in the area of the site are expected to increase at a conservative globa l growth rate of 3% per year. It is assumed that the design hour ly volume (DHV) is 10% of the background ADT and that the hourly site vo lumes are an approximation of the DHV. Using the site trip generation and distribution information above, the peak hour ly volumes using PCE values are expected to increase by 9 .5% on CR 326 in 2013 du r ing the Operations & Maintenance phase. The remaining roadways are expected to see an increase in traffic of less than 5%, many less than 1 %. T able 4 summarizes expected traffic volume increases. Daily site trips are taken from the Operations & Maintenance phase in T able 3 because it is most of the life of the site.

The Bill Barrett Circle 13 Water Gathering Site exists today as a well pad site and is anticipated to be converted into a water gathering site. The site is located south of Chippc1·field L1ne (County Road 326) and east of Dry Hollow Road (County Road 331) approximately 4.5 miles south of the Town of Silt in Garfield County, Colorado. Access to the proposed water gathering site will be from the existing access along Chipperfield Lane (CR 326) and the existing access along Dry Hollow Road (CR 331). The attached figure illustrates the site location and the existing access in relation to the Town of Silt. Site-generated traffic csti1natcs are determined through a process knovm as trip generation. for this study, Kimley-Hom used infonnation provided by the client to detenninc the number of vehicles anticipated to access the site per day, as \Vell as the numberofvchicles anticipated to enter and exit the site during the AM and PM peak hours. 111cse trip generation estimates include the number and types of vehicles that are anticipated to access the site. During normal operations for the Bill Barrett Circle B Water Gathering Site it is anticipated tlrnt the total number of vehicles that will access the facility dunng a typical day would be approximately fifteen ( 15) vehicles. A vehicle entering U1e site and exiting the site counts as two trips; therefore, a total of 30 vehicle trips in and out of the site arc anticipated per day during typical open.1tio11s of the water gnthcrjng site. 'fhese vehicles \Vould include 111ostly 80 barrel tanker !nicks and occasionally 130 barrel tanker trucks.

This permit incorporates and shall be considered a Construction Permit for any engine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. A 1 Engine Replacement The following AOS is incorporated into this permit in order to deal with a compressor engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. "Temporary" is defined as in the same service for 90 operating days or less in any 12 month period. "Permanent" is defined as in the same service for more than 90 operating days in any 12 month period. The 90 days is the total number of days that the engine is in operation. If the engine operates only part of a day, that day shall count as a single day towards the 90-day total. The compliance demonstrations and any periodic monitoring required by this AOS are in addition to any compliance demonstrations or periodic monitoring required by this permit. All replacement engines are subject to all federally applicable and state-only requirements set forth in this permit (including monitoring and record keeping). The results of all tests and the associated calculations required by this AOS shall be submitted to the Division within 30 calendar days of the test or within 60 days of the test if such testing is required to demonstrate compliance with NSPS or MACT requirements. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on-site and contemporaneously record the start and stop date of any engine replacement, the manufacturer, date of manufacture, model number, horsepower, and serial number of the engine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement engine. In addition to the log, the permittee shall maintain a copy of all Applicability Reports required under section A 1.2 and make them available to the Division upon request. A.1.1 The permittee may temporarily replace an existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower or a different manufacturer, model, or horsepower as the existing engine without modifying this permit, so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section A.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section A.2. A.1.2 The permittee may permanently replace the existing compressor engine with an engine that is of the same manufacturer, model and horsepower without modifying this permit so long as the emissions from the permanent replacement engine comply with 1) the permitted annual emission limitations for the AIRS ID: 045/1784 Page 13 of 17 Bill Barrett Corporation Permit No. 09GA0513 Issuance 4 Colorado Department of Public Health and Environment Air Pollution Control Division existing engine, 2) any permitted short-term emission limitations for the existing permitted engine, and 3) the applicable emission limitations as set forth in the Applicability Report submitted to the Division with the Air Pollutant Emissions Notice (APEN) for the replacement engine (see http://www.cdphe.state.co.us/ap/oilgaspermittinq.html for example applicability report formats). Measurement of emissions from the permanent replacement engine and compliance with the applicable emission limitations shall be made as set forth in section A.2. An Air Pollutant Emissions Notice (APEN) that includes the specific manufacturer, model and serial number and horsepower of the permanent replacement engine shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee, a cover letter explaining that the permittee is exercising an alternative operating scenario and is installing a permanent replacement engine, and a copy of the relevant Applicability Reports for the replacement engine. Example Applicability Reports can be found at http://www.cdphe.state.co.us/ap/oilqaspermitting.html. This submittal shall be accompanied by a certification from a person legally authorized to act on behalf of the source indicating that "based on the information and belief formed after reasonable inquiry, the statements and information included in the submittal are true, accurate and complete". This AOS cannot be used for permanent engine replacement of a grandfathered or permit exempt engine or an engine that is not subject to emission limits. The permittee shall agree to pay fees based on the normal permit processing rate for review of information submitted to the Division in regard to any permanent engine replacement. A.2 Portable Analyzer Testing Note: In some cases there may be conflicting and/or duplicative testing requirements due to overlapping Applicable Requirements. In those instances, please contact the Division Field Services Unit to discuss streamlining the testing requirements. Note that the testing required by this Condition may be used to satisfy the periodic testing requirements specified by the permit for the relevant time period (i.e. if the permit requires quarterly portable analyzer testing, this test conducted under the AOS will serve as the quarterly test and an additional portable analyzer test is not required for another three months). The permittee may conduct a reference method test, in lieu of the portable analyzer test required by this Condition, if approved in advance by the Division. The permittee shall measure nitrogen oxide (NOX) and carbon monoxide (CO) emissions in the exhaust from the replacement engine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the replacement engine. All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual (tons/year) or short term (lbs/unit of time) emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. AIRS ID: 045/1784 Page 14 of 17 Bill Barrett Corporation Permit No. 09GA0513 Issuance 4 Colorado Department of Public Health and Environment Air Pollution Control Division For comparison with a short-term limit that is either input based (lb/mmBtu), output based (g/hp-hr) or concentration based (ppmvd @ 15% 02) that the existing unit is currently subject to or the replacement engine will be subject to, the results of the test shall be converted to the appropriate units as described in the above-mentioned Portable Analyzer Monitoring Protocol document. If the portable analyzer results indicate compliance with both the NOX and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOX and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOX or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOX and CO emission limitations or until the engine is taken offline. A.3 Applicable Regulations for Permanent Engine Replacements A.3. 1 Reasonably Available Control Technology (RACT): Reg 3, Part B § 11.D.2 All permanent replacement engines that are located in an area that is classified as attainmenUmaintenance or nonattainment must apply Reasonably Available Control Technology (RACT) for the pollutants for which the area is attainmenUmaintenance or nonattainment. Note that both VOC and NOX are precursors for ozone. RACT shall be applied for any level of emissions of the pollutant for which the area is in attainmenUmaintenance or nonattainment, except as follows: In the Denver Metropolitan PM10 attainmenUmaintenance area, RACT applies to PM10 at any level of emissions and to NOX and S02, as precursors to PM1 O, if the potential to emit of NOX or S02 exceeds 40 tons/yr. For purposes of this AOS, the following shall be considered RACT for natural-gas fired reciprocating internal combustion engines: voe: CO: NOX: S02: PM10: The emission limitations in NSPS JJJJ The emission limitations in NSPS JJJJ The emission limitations in NSPS JJJJ Use of natural gas as fuel Use of natural gas as fuel As defined in 40 CFR Part 60 Subparts GG (§ 60.331) and 40 CFR Part 72 (§ 72.2), natural gas contains 20.0 grains or less of total sulfur per 100 standard cubic feet. A.3.2 Control Requirements and Emission Standards: Regulation No. 7, Sections XVI. and XVll.E (State-Only conditions). Control Requirements: Section XVI Any permanent replacement engine located within the boundaries of an ozone nonattainment area is subject to the applicable control requirements specified in Regulation No. 7, section XVI, as specified below: Rich burn engines with a manufacturer's design rate greater than 500 hp shall use a non- selective catalyst and air fuel controller to reduce emission. AIRS ID: 045/1784 Page 15 of 17 Bill Barrett Corporation Permit No. 09GA0513 Issuance 4 Colorado Department of Public Health and Environment Air Pollution Control Division Lean burn engines with a manufacturer's design rate greater than 500 hp shall use an oxidation catalyst to reduce emissions. The above emission control equipment shall be appropriately sized for the engine and shall be operated and maintained according to manufacturer specifications. The source shall submit copies of the relevant Applicability Reports required under Condition A.1.2. Emission Standards: Section XVII. E -State-only requirements Any permanent engine that is either constructed or relocated to the state of Colorado from another state, after the date listed in the table below shall operate and maintain each engine according to the manufacturer's written instructions or procedures to the extent practicable and consistent with technological limitations and good engineering and maintenance practices over the entire life of the engine so that it achieves the emission standards required in the table below: Max Engine HP Construction or Emission Standards in Glhp-hr Relocation Date NOx co voe January 1, 2008 2.0 4.0 1.0 100<Hp<500 January 1, 2011 1.0 2.0 0.7 500::_Hp July 1, 2007 2.0 4.0 1.0 July 1, 2010 1.0 2.0 0.7 The source shall submit copies of the relevant Applicability Reports required under Condition A.1.2 A.3.3 NSPS for spark ignition internal combustion engines: 40 CFR 60, Subpart JJJJ A permanent replacement engine that is manufactured on or after 711/09 for emergency engines greater than 25 hp, 7/1/2008 for engines less than 500 hp, 71112007 for engines greater than or equal to 500 hp except for lean burn engines greater than or equal to 500 hp and less than 1,350 hp, and 1/1/2008 for lean burn engines greater than or equal to 500 hp and less than 1,350 hp are subject 40 CFR 60, Subpart JJJJ. An analysis of applicable monitoring, record keeping, and reporting requirements for the permanent engine replacement shall be included in the Applicability Reports required under Condition A.1.2. Any testing required by the NSPS is in addition to that required by this AOS. Note that the initial test required by NSPS Subpart JJJJ can serve as the testing required by this AOS under Condition A.2, if approved in advance by the Division, provided that such test is conducted within the time frame specified in Condition A.2. Note that under the provisions of Regulation No. 6. Part B, section 1.8. that Relocation of a source from outside of the State of Colorado into the State of Colorado is considered to be a new source, subject to the requirements of Regulation No. 6 (i.e., the date that the source is first relocated to Colorado becomes equivalent to the manufacture date for purposes of determining the applicability of NSPS JJJJ requirements). However, as of November 1, 2008 the Division has not yet adopted NSPS JJJJ. Until such time as it does, any engine subject to NSPS will be subject only under Federal law. Once the Division adopts NSPS JJJJ, there will be an additional step added to the determination of the NSPS. Under the provisions of Regulation No. 6, Part B, § I. B (which is referenced in Part A), any engine relocated from outside of the State of Colorado into the State of Colorado is considered to be a new source, subject to the requirements of NSPS JJJJ.

An analysis of the applicable monitoring, recordkeeping, and reporting requirements for the permanent engine replacement shall be included in the Applicability Reports required under Condition A 1.2. Any testing required by the MACT is in addition to that required by this A.OS. Note that the initial test required by the MA.CT can serve as the testing required by this A.OS under Condition A.2, if approved in advance by the Division, provided that such test is conducted within the time frame specified in Condition A.2. A.3.4.2 Major source for HAPs A permanent replacement engine that is located at major source is subject to the requirements in 40 CFR Part 63 Subpart ZZ.ZZ as follows: Existing, new or reconstructed spark ignition 4 stroke rich burn engines with a site rating of more than 500 hp are subject to the requirements in 40 CFR Part 63 Subpart llll. New or reconstructed (construction or reconstruction commenced after 12/19/02) 2 stroke and 4 stroke lean burn engines with a site rating of more than 500 hp are subject to the requirements in 40 CFR Part 63 Subpart ZZZZ. New or reconstructed (construction or reconstruction commenced after 6/12/06) 4 stroke lean burn engines with a site rating of greater than or equal to 250 but less or equal to 500 hp and were manufactured on or after 1/1/08 are subject to the requirements in 40 CFR Part 63 Subpart zzzz.. New or reconstructed (construction or reconstruction commenced after 6/12/06) 2 stroke lean burn or 4 stroke rich burn engines with a site rating of 500 hp or less will meet the requirements of 40 CFR 63, Subpart ZZZZ. by meeting the requirements of 40 CFR 60, Subpart JJJJ. New or reconstructed (construction or reconstruction commenced after 6/12/06) 4 stroke lean burn engines with a site rating of less than 250 hp will meet the requirements of 40 CFR 63, Subpart ZZll by meeting the requirements of 40 CFR 60, Subpart JJJJ. An analysis of the applicable monitoring, recordkeeping, and reporting requirements for the permanent engine replacement shall be included in the Applicability Reports required under Condition A.1.2. Any testing required by the MA.CT is in addition to that required by this A.OS. Note that the initial test required by the MA.CT can serve as the testing required by this A.OS under Condition A.2, if approved in advance by the Division, provided that such test is conducted within the time frame specified in Condition A.2. A.3.5 Additional Sources The replacement of an existing engine with a new engine is viewed by the Division as the installation of a new emissions unit, not "routine replacement" of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; an engine that is being installed as an entirely new emission point and not as part of an AOS- approved replacement of an existing onsite engine has to go through the appropriate Construction/Operating permitting process prior to installation.

Introduction Serious incident situations, unless properly controlled, can result in loss of life and damage to public or private property. Situations resulting from spills can generate complex technical, legal and public relations problems. It cannot be overemphasized that the best way to handle emergency situations is to prevent their occurrence. This Plan is designed to help Bill Barrett Corporation (BBC) respond quickly and effectively to the problems presented by serious incidents when they do occur. The Plan's primary goal is to help the company prevent, as far as practical, any loss of life or damage to property, wildlife, or the ecology. Within this Response Plan you will find descriptions of the duties that must be accomplished when a serious incident occurs. It provides personnel with procedures for handling such incidents effectively. The Plan is prepared: 1. To serve as the basis for an organized action plan in dealing with emergencies and spills of all magnitudes. 2. To spell out responsibility, priority and importance in countering an emergency situation or major spill. 3. To provide information on the means of handling serious incidents and identify the organizations that are involved. 4. To tabulate the personnel and agencies that must be notified. Prompt action is mandatory. For this reason, the content of this Plan must be understood by the persons who may have need of it. All involved employees should be informed to take quick action to protect life and property and to immediately report the incident. The plan will require modification from time to time, as personnel change, as technologies advance, and as experience indicates improvements. The plan is to be reviewed annually by the EH&S staff to assure that it is up to date. This plan is not intended to replace existing Spill Prevention Control & Countermeasures (SPCC) Plans or other required Plans, but rather its purpose is to be a supplement providing general guidelines for emergency situations.

Communication I Evidence It is important when an emergency is identified that notification to an employee's supervisor is made as soon as possible. It is mandatory that notices be given internally as soon as practical. Notification will follow the reporting hierarchy for BBC. The first person to identify the emergency will report ii to his/her supervisor. If a person's supervisor cannot be immediately reached with the known contact (i.e. telephone numbers of home, office, portable phone, or pager) then the next person on the list must be notified. At each notification, instructions may be received to be implemented. Each person receiving notification then is responsible for contacting up the chain of command. Notification to regulatory authorities should be made only after discussion the situation with the Senior onsite BBC Supervisor. Communication Techniques 1. Communication must be through a two-way confirmed means. Use of messages on a voice recorder or answering machine does not constitute notification. A message may be left, but the next person up the chain of command must be contacted. 2. If a line is busy, advise the operator that you have an emergency and get the operator to interrupt the line. 3. Make sure the person you are communicating with understands you. This can be done by asking them to repeat key parts of your discussion. 4. If you are calling someone you do not frequently talk to, make sure you identify yourself and where you can be reached. 5. If working with a radio communication, call out the person you want to talk to followed by your name (E.G. "Kurt, this is Greg, do you read me?") Wait long enough for a response. The person may be away from the radio and may need some time to get back, 6. If calling by telephone, let the phone ring at least six times before hanging up. 7. Do not hesitate to call above your supervisor if your supervisor is unreachable. 8. Have relevant information available before starting notification. This does not mean a complete report of everything, but as a minimum the following: A. Location or facility and call back phone number B. Type of emergency. C. Time and date first noticed. D. Magnitude of emergency (e.g. size of fire or spill, number of people involved, injuries, if other properties or companies are involved). E. What you have done prior to making your notification. F. What your plans are in responding to the emergency. G. What are the weather conditions? H. What, if any, outside notifications have been made. I. What assistance you need. J. When you will call back with a subsequent report. Communication Equipment The primary means of communications will be by telephone and radio. Field operations that are Company operated will utilize two-way radio(s) communications and/or mobile telephones. Communications are designed to allow supervisors to be in contact with the Region office. Drillings rigs are usually equipped with either radio systems that communicate with the drilling contractor or mobile telephones. All drilling locations will have some means of two-way communications either onsite or within a 15-minute drive (all types of weather). Community/Public Affairs Communication and public affairs are best handled by persons trained in dealing with the media. All media inquiries should be directed to the Regulatory/Public Relations and/or Legal Department unless specific direction is given by these groups to individual personnel. Estimates or speculations as to cause or size of the problem must never be made. Assume any camera or recorder in the area is ON at all times (it just may be}. Encourage the media to speak with Public Relations or Legal Department personnel in the Denver office for any detailed information. Preserving the Evidence In the aftermath of a serious incident, it becomes necessary to investigate the incident in order to determine cause and corrective actions. Perhaps the most important aspect of this investigation is determining the facts, and as such, the preservation of the evidence is of great importance. With the assistance of personnel involved at the incident scene, the evidence can be preserved and a more beneficial investigation performed. The following are basic guidelines which should be followed: 1. Secure the Area Rope off or other control access into the incident site. Access by non- company personnel (including contractor personnel even if involved in the incident) is NOT allowed unless specific management approval has been obtained. The only exception being necessary access by emergency medical rescuers and fire fighters. 2. Preserve the Evidence As much as possible, don't disturb objects relating to the incident. If unavoidable, stake or mark its location and record what was there. Never allow evidence to leave the scene without approval. 3. Document the Evidence The Incident Leader is responsible for preserving all documentation until the investigator(s) arrive at the scene. 4. Identify Witnesses If persons who witnessed the incident cannot remain on the scene to be interviewed during the investigation, get their names and pertinent information so that they can be located later. VII. HAZWOPER INDEX • Introduction • HAZWOPER Plan Narrative A. Pre-Emergency Planning B. Personnel Roles and Line of Authority C. Evacuation, Safe Distances, and Places of Refuge D. Employee Safety During a Hazwoper Response E. Response Evaluation & Follow-Up HAZWOPER Introduction HAZWOPER stands for "Hazardous Waste Operations and Emergency Response". HAZWOPER is a regulation designed to establish a management plan for emergencies involving hazardous materials. It is applicable to oil field operations primarily through the regulations addressing emergency responses to hazardous substance releases. HAZWOPER defines an emergency response, or responding to emergencies, as a response effort by employees from outside the immediate release area or by other designated responders (e.g., local fire departments, mutual-aid groups, designated HAZMAT Team, etc.) to an occurrence which results or potentially results in an uncontrolled release of a hazardous substance. For the purposes of this plan, the term "immediate release area" has been defined as encompassing the Superintendent's/Area Foreman's geographical area; therefore, if an emergency situation can be mitigated by Company personnel, it is not a HAZWOPER Emergency. In the event that an uncontrolled release requires the response of specially trained emergency teams to stop or control the release (e.g. Fire Department, Department of Health Services, etc.), it is a HAZWOPER response and the procedures in this section of the "Response Manual" must be followed. The EH&S and Legal Departments must be immediately notified in this instance. HAZWOPER Plan Narrative A. Preplanning Response Actions Preplanning is the key to a successful emergency management plan. Planning is handled through the training of company employees, formulation of emergency response activities, and pre-planned coordination with outside emergency responders. The following items constitute BBC's preplanning actions. All field employees will be trained in Hazard Communication and Emergency Response. This includes hazardous material container labeling, access to, and understanding Material Safety Data sheets, and responding to emergencies involving hazardous materials. Specific emergency scenarios and appropriate responses will be discussed in these training sessions. In the event of a HAZWOPER emergency, response activities will be coordinated with contract companies trained to respond to HAZWOPER. The names of these companies and their emergency numbers can be found in Sections Ill and IV of this Plan. B. Personnel Roles and Lines of Authority If an incident is classified as a HAZWOPER response, the Superintendent/ Area Foreman responsible for the facility requiring the response shall supervise BBC personnel in emergency response activities and perform all reporting requirements pursuant to this Emergency Response Plan. He/she will continue to perform these duties until such time as the responding Emergency Response Team arrives. Upon the arrival of the trained Emergency Response (ER) Team, the ranking official of said team will coordinate with the BBC Incident Leader. After that point, all emergency response activities will be conducted under the direction of the ER and Incident Leader. C. Evacuation, Safe Distances, and Places of Refuge Evacuation -The open air nature of oil and gas operations generally permits numerous safe evacuation routes. In areas where this is not the case, employees are directed to attempt escape along a route that takes them upwind of an incident. Crosswind escape is suggested only until upwind escape is appropriate. Wind direction indicators are installed on all properties where H2S gas has been identified. Safe Distances -Prior to the arrival of the Incident Leader mentioned in Section B, the Superintendent/Area Foreman or designee shall be responsible for establishing the distance from the hazardous scene. After the Incident Leader arrives on the scene, safe distances will be established at his/her discretion. Places of Refuge should be established as appropriate for BBC operations. D. Employee Safety During a HAZWOPER Response All field employees will be trained to insure that they can operate certain equipment on the property during an emergency in order to bring the emergency condition under control. In the course of these operations the employee may be exposed to a hazardous environment, become injured, or have his/her clothing become contaminated with a hazardous material. The following items will address these issues. Personal Protection Eauioment Specific (PPE) is available to every employee. The type of equipment available to the employee will vary depending on the hazards inherent in the subject work area. Selection, safe use, limitations, maintenance, care and storage will be covered in employee training. The Company's policies and procedures pertaining to PPE are found in the EH&S Manual located in each area office. Employees should only respond to an incident if the hazards are obvious and that employee is trained to respond to the specific hazards involved and the proper PPE is available. Emergency Medical Services will be provided by local hospitals, urgent care centers, and fire departments. Services have been identified in Section IX of this Plan and are listed by BBC operating area name. Decontamination of clothing equipment will be coordinated with BBC EH&S staff. The MSDS will be consulted for proper disposal of contaminated items. E. Response Evaluation & Follow-Up After a HAZWOPER response has occurred, the Emergency Response Review committee will submit a report to management discussing the emergency response as requested. A copy of this report will be kept in the files. The Emergency Response Review Committee: • Operations/Area Manager • Environmental, Health & Safety Manager • SuperintendenUArea Foreman The report will identify: • Nature and Cause of emergency • Statistics pertaining to emergency (i.e. damage, injuries, etc.) • Effectiveness of Company Emergency Response Personnel • Corrective Measures taken to prevent recurrence of similar emergency at this location (considering applicability to other locations) VIII. H 2 S CONTINGENCY PLAN SCOPE The purpose of this Section is to provide an organized plan of action to protect the general public and employees in the event of an accidental release of a potentially hazardous volume of hydrogen sulfide (H 2S), or other toxic/hazardous gas.

Page 11of16 Article 7 Standards-Division 3 1.0 INTRODUCTION The following section addresses the requirements for the Site Planning and Development Standards under Article 7, Division 3 of the Garfield County Unified Land Use Resolution of 2008, as amended. 2.0 SECTION 7-301. COMPATIBLE DESIGN. The design of Development associated with the Land Use Change shall be compatible with and enhance the existing character of adjacent uses. A. Site Organization. The site shall be organized in a way that considers the relationship to streets and lots, solar access, parking, pedestrian access, and access to common areas. The proposed site is located in an unpopulated area on a 280 acre parcel and not adjacent to public streets, parking, pedestrian access, and common areas. The site will not impede solar access to adjacent parcels. The site plan is located in the Maps and Plans tab. The vicinity map is located in the Impact Analysis tab. B. Operational Characteristics. The operations of activities on the site shall be managed to avoid nuisances to adjacent uses relating to hours of operations, parking, service delivery, and location of service areas and docks. 1. Objectionable Emissions. Dust, odors, gas,fumes, and glare shall not be emitted at levels that are objectionable to adjacent property. The site will not produce nuisances that are objectionable to adjacent property. An air permit was obtained from the Colorado Department of Public Health Environment (CDPHE) on April 18, 2012. Copies of the air permit and associated documents are provided in the Impact Analysis Tab. Lighting will be installed atthe CB#6GLCF. All lighting will comply with Section 7-306 Lighting Standards. Odors, gas, and fumes are not anticipated at the proposed site. Z. Noise. Noise shall not exceed state noise standards pursuant to C.R.S., Article 12 of Title 25, as amended, unless the use is regulated by the COGCC. In this case, the use shall be subject to COGCC Rule 802, Noise Abatement. Bill Barrett Corporation (BBC) retained Noise Solutions, Inc. (NS!) to perform an analysis of the noise expected to be generated by the proposed compressor station and mitigation efforts that may be required so that the station will meet the applicable COGCC standards. Per COGCC Rule 802.c.(1), noise measurements shall be measured at 350 feet or the property line, whichever is greater. Therefore, NSI was asked to analyze the expected noise levels at the property lines closest to the proposed facility-594 feet east and 607 feet south. In addition, the expected noise levels at the four residences closest to the proposed facility were evaluated to ensure that noise levels at those residences would meet the applicable standards. For noise levels on the db( A) scale, the residential standard from COGCC Rule 802.c. was used as the applicable regulatory standard. For noise levels on the db(C) scale, the standard of 65 db(C) at the residences was used for this evaluation. Initially, NS! analyzed the noise level expected to result from this facility with no building over the compressors and also with a bare (uninsulated) building. Noise levels under these scenarios were predicted for each of the six receptor locations. Because the predicted noise levels exceeded the Page 12of16 applicable standards, NSI then analyzed a series of mitigation measures that could be employed to meet the standards. These analyses are provided in Tables 12-17 in the report included in the Impact Analysis Tab. BBC will employ all of these mitigation measures at this facility. Tables 12-13 indicate that the db( A) noise levels at the property line would meet the COGCC residential standard, and Tables 14-17 indicate that the db(C) levels at each of the residences would meet the COGCC standard. The Noise Analysis is provided in the Impact Analysis tab. 3. Hours of Operation. Hours of operation shall be established to minimize impacts to adjacent land uses. The proposed site will not be manned on a continuous basis with personnel only being present when maintenance is required. Maintenance should only occur during daylight hours except in the event of an emergency. 4. Roadway System Impacts. Impacts to the County roadway system associated with hauling, truck traffic, and equipment use shall be mitigated through roadway improvements or impact fees, or both. A Trip Generation Memorandum (TGM) and a previous Traffic Analysis are provided in the Impact Analysis tab. The TGM determined that traffic will increase on County Road 326 by 0.6% based on daily trips. No auxiliary lanes are recommended for the proposed site. Impacts are considered to be negligible to public roads. C. Lighting. Exterior lighting shall be designed in compliance with the requirements of Section 7-306, Lighting Standards. Lighting for the site will require electricity which is available at the location. All lighting will comply with the Lighting Standards, Section 7-306 of the Garfield County Unified Land Use Resolution of 2008. D. Buffering. Buffering shall be installed to mitigate visual, noise, or similar impacts to adjacent property whenever adjacent uses are in a different zoning district. The subject parcel and adjacent parcels are all zoned rural. The site will be located on a 280 acre parcel and not within close proximity to other residents or businesses. E. Materials. Exterior facades shall be constructed with materials that do not detract from adjacent buildings or uses. The building will be constructed with standard red-iron with 26 gauge skin. Noise attenuating insulation will be installed within the building. The building dimensions will be 60 foot x 76 foot with a 22 foot eave height. The building height is within the maximum building height range for the rural zone district The structure will be painted tan or BLM green and will blend in with the natural background environment. F. Building Scale. The scale of buildings on the site shall relate to the scale of structures on adjacent properties and the nature of the proposed use.

Any activity requiring that will generate noise, odors, or glare beyond the property boundaries will be conducted between the hours of 7:00 a.m. to 7:00 p.m. Monday through Saturday, or as approved by the decision-making authority. All activities involving personnel will be held within the 7:00 a.m. to 7:00 p.m. unless in the case of emergency. The proposed site will be located on a 280 acre parcel in a non-populated rural area. Hazards, nuisance, or interference to adjacent parcels is not anticipated. Current oil and gas activities exist on the property. The proposed site location will be located entirely within the disturbed footprint of a well pad permitted by COGCC. The site is designed to minimize impacts. G. Industrial Wastes. All industrial wastes shall be disposed of in a manner consistent with Federal and State statutes and requirements ofCDPHE. All industrial wastes will be disposed of in a manner consistent with Federal and State statutes and requirements of CDP HE. Produced water will be transported to the Circle B Water Management facility located on the subject parcel. Oil waste from the compressor station will be hauled by Mesa Environmental to a recycling facility under an existing contract with BBC. H. Noise. Noise shall not exceed State noise standards pursuant to C.R.S., Article 12, Title 25, as amended, unless the use is regulated by the COGCC. In this case, the use shall be subject to COGCC Rule 802, Noise Abatement. Bill Barrett Corporation (BBC) retained Noise Solutions, Inc. (NSl) to perform an analysis of the noise expected to be generated by the proposed compressor station and mitigation efforts that may be required so that the station will meet the applicable COGCC standards. Per COGCC Rule 802.c.(l), noise measurements shall be measured at 350 feet or the property line, whichever is greater. Therefore, NSI was asked to analyze the expected noise levels at the property lines closest to the proposed facility-594 feet east and 607 feet south. In addition, the expected noise levels at the four residences closest to the proposed facility were evaluated to ensure that noise levels at those residences would meet the applicable standards. For noise levels on the db[A) scale, the residential standard from COGCC Rule 802.c. was used as the applicable regulatory standard. For noise levels on the db(C) scale, the COGCC standard of 65 db(C) at the residences was used for this evaluation. Initially, NSI analyzed the noise level expected to result from this facility with no building over the compressors and also with a bare [uninsulated) building. Noise levels under these scenarios were predicted for each of the six receptor locations. Because the predicted noise levels exceeded the applicable standards, NSI then analyzed a series of mitigation measures that could be employed to meet the standards. These analyses are provided in Tables 12-17 in the report included in the Impact Analysis Tab. BBC will employ all of these mitigation measures at this facility. Tables 12-13 indicate that the db[A) noise levels at the property line would meet the COGCC residential standard, and Tables 14-17 indicate that the db(C) levels at each of the residences would meet the COGCC standard. The Noise Analysis is provided in the Impact Analysis tab. I. Ground Vibration. Every use shall be operated so that the ground vibration inherently and recurrently generated is not perceptible without instruments at any point of any boundary line of the property. Ground vibration will not be perceptible without instruments at any point on the property boundary line. J. Interference, Nuisance, or Hazard.

Flaring of gases, aircraft warning signal, and reflective painting of storage tanks, or other legal requirements for safety or air pollution control measures shall be exempted from this provision. The proposed site will be located on a 280 acre parcel in a non-populated rural area. Hazards, nuisance, or interference to adjacent parcels is not anticipated. Current oil and gas activities exist on the property. The proposed site location will be located entirely within the disturbed footprint of a well pad permitted by COGCC. The site is designed to minimize impacts. A noise analysis was conducted using the standards stated by COGCC. The proposed use will not cause air quality to be reduced below acceptable levels established by the Colorado Air Pollution Control Division. CDPHE Air Permit and the Noise Analysis Study are located in the Impact Analysis tab. Bill Barrett Corporation CB6 PR Compressor Section 7-202 Protection of Wildlife Habitat Areas Garfield County Unified Land Use Resolution 2008 WILDLIFE Threatened and Endangered Species No threatened or endangered species are expected to be affected. Critical habitat for four endangered fishes exists downstream of the project in the Colorado River. Storm water and runoff controls already in place for the existing Circle B #6 well pad and access road should be sufficient to prevent increased sedimentation or potential contaminants from reaching the river. Raptors Activities associated with the compressor site have minimal potential to impact raptor populations as no nesting habitat is directly affected and no raptor nests were documented wihtin 0.25 miles of the site in 2012. Activities associated with operation of the compressor will have little indirect effect on raptors given the cumulative scale of ongoing activities in the area and the large amount of unaffected habitat surrounding the site. American Elk and Mule Deer The area surrounding the proposed compressor is of high value to big game species, especially during the winter when snow accumulations cover the forage at higher elevations. Native vegetation was previously removed from the site for development of the Circle B #6 well pad. The current weed control strategies appear moderately effective and noxious weeds are not abundant, although several nuisance plant species are dominant among the vegetation that does exist. Human activities at the site should be limited to the daylight hours as much as possible, particularly during winter months, to reduce stress on big game animals during the important foraging hours from approximately one hour before dusk to one hour after dawn. Black Bear Black bear may forage in the project area. All garbage and food items should be removed from the site on a daily basis. Personnel should be informed of the potential for bear interactions and bears should not be approached or fed at any time. Bears that become habituated to human presence and unnatural food sources are often euthanized if they become a threat to humans. Mitigation of Habitat Loss to Birds Because the native vegetation has little nesting value for most passerine birds in this area, and there is an abundance of better nesting habitat available for foraging nearby, the effects of this project on bird species should be minimal. The current weed control strategies appear moderately effective. The excess disturbance area surrounding the project should be revegetated, further reducing the chance for noxious weed establishment and ensuring forage availability to the greatest extent possible. WestWater Engineering Page 1 of2 November 2012 Small Mammals and Reptiles There are no seasonal restrictions or special requirements for development related to these species. PRESERVATION OF NATIVE VEGETATION The compressor site would be situated in an area that has been cleared of native vegetation for other projects. Revegetation of disturbed areas surrounding the compressor should consist of grasses and forbs both for mitigating erosion and to decrease the effect of habitat loss for wildlife to the greatest extent possible. Treatment and Control of Noxious Weed Iufestatious The highest priority for noxious weed management should be to control the existing infestation of Russian knapweed and to prevent the establishment of any additional noxious weed infestations on the project site. Noxious weeds aggressively compete with native vegetation. Most have come from Europe or Asia, either accidentally or as ornamentals that have established in the wild. Once established, they tend to spread quickly because the insects, diseases, and animals that normally control them are absent. Prevention is especially valuable in the case of noxious weed management. Noxious weeds are spread by man, animals, water, and wind. Prime locations for the establishment of noxious weeds include roadsides, construction sites, wetlands, riparian corridors, and areas that are overused by animals or humans. 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. Several simple practices should be employed to prevent most weed infestations. The following practices should be adopted for any activity to reduce the costs of noxious weed control through prevention. The practices include: • Prior to delivery to the site, equipment should be thoroughly cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds. • If working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris at the infested area prior to moving to uncontaminated terrain. • All maintenance vehicles should be regularly cleaned of soil. • Avoid driving vehicles through areas where weed infestations exist.

Introduction Serious incident situations, unless properly controlled, can result in loss of life and damage to public or private property. Situations resulting from spills can generate complex technical, legal and public relations problems. It cannot be overemphasized that the best way to handle emergency situations is to prevent their occurrence. This Plan is designed to help Bill Barrett Corporation (BBC) respond quickly and effectively to the problems presented by serious incidents when they do occur. The Plan's primary goal is to help the company prevent, as far as practical, any loss of life or damage to property, wildlife, or the ecology. Within this Response Plan you will find descriptions of the duties that must be accomplished when a serious incident occurs. It provides personnel with procedures for handling such incidents effectively. The Plan is prepared: 1. To serve as the basis for an organized action plan in dealing with emergencies and spills of all magnitudes. 2. To spell out responsibility, priority and importance in countering an emergency situation or major spill. 3. To provide information on the means of handling serious incidents and identify the organizations that are involved. 4. To tabulate the personnel and agencies that must be notified. Prompt action is mandatory. For this reason, the content of this Plan must be understood by the persons who may have need of it. All involved employees should be informed to take quick action to protect life and property and to immediately report the incident. The plan will require modification from time to time, as personnel change, as technologies advance, and as experience indicates improvements. The plan is to be reviewed annually by the EH&S staff to assure that it is up to date. This plan is not intended to replace existing Spill Prevention Control & Countermeasures (SPCC) Plans or other required Plans, but rather its purpose is to be a supplement providing general guidelines for emergency situations.

Incidents that could significantly impact the Company's cash flow and/ or financial performance. VI. Communication I Evidence It is important when an emergency is identified that notification to an employee's supervisor is made as soon as possible. It is mandatory that notices be given internally as soon as practical. Notification will follow the reporting hierarchy for BBC. The first person to identify the emergency will report it to his/her supervisor. If a person's supervisor cannot be immediately reached with the known contact (i.e. telephone numbers of home, office, portable phone, or pager) then the next person on the list must be notified. At each notification, instructions may be received to be implemented. Each person receiving notification then is responsible for contacting up the chain of command. Notification to regulatory authorities should be made only after discussion the situation with the Senior onsite BBC Supervisor. Communication Techniques 1. Communication must be through a two-way confirmed means. Use of messages on a voice recorder or answering machine does not constitute notification. A message may be left, but the next person up the chain of command must be contacted. 2. If a line is busy, advise the operator that you have an emergency and get the operator to interrupt the line. 3. Make sure the person you are communicating with understands you. This can be done by asking them to repeat key parts of your discussion. 4. If you are calling someone you do not frequently talk to, make sure you identify yourself and where you can be reached. 5. If working with a radio communication, call out the person you want to talk to followed by your name (E.G. "Kurt, this is Greg, do you read me?") Wait long enough for a response. The person may be away from the radio and may need some time to get back, 6. If calling by telephone, let the phone ring at least six times before hanging up. 7. Do not hesitate to call above your supervisor if your supervisor is unreachable. 8. Have relevant information available before starting notification. This does not mean a complete report of everything, but as a minimum the following: A. Location or facility and call back phone number B. Type of emergency. C. Time and date first noticed. D. Magnitude of emergency (e.g. size of fire or spill, number of people involved, injuries, if other properties or companies are involved). E. What you have done prior to making your notification. F. What your plans are in responding to the emergency. G. What are the weather conditions? H. What, if any, outside notifications have been made. I. What assistance you need. J. When you will call back with a subsequent report. Communication Equipment The primary means of communications will be by telephone and radio. Field operations that are Company operated will utilize two-way radio(s) communications and/or mobile telephones. Communications are designed to allow supervisors to be in contact with the Region office. Drillings rigs are usually equipped with either radio systems that communicate with the drilling contractor or mobile telephones. All drilling locations will have some means of two-way communications either onsite or within a 15-minute drive (all types of weather). Community/Public Affairs Communication and public affairs are best handled by persons trained in dealing with the media. All media inquiries should be directed to the Regulatory/Public Relations and/or Legal Department unless specific direction is given by these groups to individual personnel. Estimates or speculations as to cause or size of the problem must never be made. Assume any camera or recorder in the area is ON at all times (it just may be). Encourage the media to speak with Public Relations or Legal Department personnel in the Denver office for any detailed information. Preserving the Evidence In the aftermath of a serious incident, it becomes necessary to investigate the incident in order to determine cause and corrective actions. Perhaps the most important aspect of this investigation is determining the facts, and as such, the preservation of the evidence is of great importance. With the assistance of personnel involved at the incident scene, the evidence can be preserved and a more beneficial investigation performed. The following are basic guidelines which should be followed: 1. Secure the Area Rope off or other control access into the incident site. Access by non- company personnel (including contractor personnel even if involved in the incident) is NOT allowed unless specific management approval has been obtained. The only exception being necessary access by emergency medical rescuers and fire fighters. 2. Preserve the Evidence As much as possible, don't disturb objects relating to the incident. If unavoidable, stake or mark its location and record what was there. Never allow evidence to leave the scene without approval. 3. Document the Evidence The Incident Leader is responsible for preserving all documentation until the investigator(s) arrive at the scene. 4. Identify Witnesses If persons who witnessed the incident cannot remain on the scene to be interviewed during the investigation, get their names and pertinent information so that they can be located later. VII. HAZWOPER INDEX • Introduction • HAZWOPER Plan Narrative A. Pre-Emergency Planning B. Personnel Roles and Line of Authority C. Evacuation, Safe Distances, and Places of Refuge D. Employee Safety During a Hazwoper Response E. Response Evaluation & Follow-Up HAZWOPER Introduction HAZWOPER stands for "Hazardous Waste Operations and Emergency Response". HAZWOPER is a regulation designed to establish a management plan for emergencies involving hazardous materials. It is applicable to oil field operations primarily through the regulations addressing emergency responses to hazardous substance releases. HAZWOPER defines an emergency response, or responding to emergencies, as a response effort by employees from outside the immediate release area or by other designated responders (e.g., local fire departments, mutual-aid groups, designated HAZMAT Team, etc.) to an occurrence which results or potentially results in an uncontrolled release of a hazardous substance. For the purposes of this plan, the term "immediate release area" has been defined as encompassing the Superintendent's/Area Foreman's geographical area; therefore, if an emergency situation can be mitigated by Company personnel, it is not a HAZWOPER Emergency. In the event that an uncontrolled release requires the response of specially trained emergency teams to stop or control the release (e.g. Fire Department, Department of Health Services, etc.), it is a HAZWOPER response and the procedures in this section of the "Response Manual" must be followed. The EH&S and Legal Departments must be immediately notified in this instance. HAZWOPER Plan Narrative A. Preplanning Response Actions Preplanning is the key to a successful emergency management plan. Planning is handled through the training of company employees, formulation of emergency response activities, and pre-planned coordination with outside emergency responders. The following items constitute BBC's preplanning actions. All field employees will be trained in Hazard Communication and Emergency Response. This includes hazardous material container labeling, access to, and understanding Material Safety Data sheets, and responding to emergencies involving hazardous materials. Specific emergency scenarios and appropriate responses will be discussed in these training sessions. In the event of a HAZWOPER emergency, response activities will be coordinated with contract companies trained to respond to HAZWOPER. The names of these companies and their emergency numbers can be found in Sections Ill and IV of this Plan. B. Personnel Roles and Lines of Authority If an incident is classified as a HAZWOPER response, the SuperintendenV Area Foreman responsible for the facility requiring the response shall supervise BBC personnel in emergency response activities and perform all reporting requirements pursuant to this Emergency Response Plan. He/she will continue to perform these duties until such time as the responding Emergency Response Team arrives. Upon the arrival of the trained Emergency Response (ER) Team, the ranking official of said team will coordinate with the BBC Incident Leader. After that point, all emergency response activities will be conducted under the direction of the ER and Incident Leader. C. Evacuation, Safe Distances, and Places of Refuge Evacuation -The open air nature of oil and gas operations generally permits numerous safe evacuation routes. In areas where this is not the case, employees are directed to attempt escape along a route that takes them upwind of an incident. Crosswind escape is suggested only until upwind escape is appropriate. Wind direction indicators are installed on all properties where H2S gas has been identified. Safe Distances -Prior to the arrival of the Incident Leader mentioned in Section B, the SuperintendenUArea Foreman or designee shall be responsible for establishing the distance from the hazardous scene. After the Incident Leader arrives on the scene, safe distances will be established at his/her discretion. Places of Refuge should be established as appropriate for BBC operations. D. Employee Safety During a HAZWOPER Response All field employees will be trained to insure that they can operate certain equipment on the property during an emergency in order to bring the emergency condition under control. In the course of these operations the employee may be exposed to a hazardous environment, become injured, or have his/her clothing become contaminated with a hazardous material. The following items will address these issues. Personal Protection Eauioment Specific (PPE) is available to every employee. The type of equipment available to the employee will vary depending on the hazards inherent in the subject work area. Selection, safe use, limitations, maintenance, care and storage will be covered in employee training. The Company's policies and procedures pertaining to PPE are found in the EH&S Manual located in each area office. Employees should only respond to an incident if the hazards are obvious and that employee is trained to respond to the specific hazards involved and the proper PPE is available. Emergency Medical Services will be provided by local hospitals, urgent care centers, and fire departments. Services have been identified in Section IX of this Plan and are listed by BBC operating area name. Decontamination of clothing equipment will be coordinated with BBC EH&S staff. The MSDS will be consulted for proper disposal of contaminated items. E. Response Evaluation & Follow-Up After a HAZWOPER response has occurred, the Emergency Response Review committee will submit a report to management discussing the emergency response as requested. A copy of this report will be kept in the files. The Emergency Response Review Committee: • Operations/Area Manager • Environmental, Health & Safety Manager • Superintendent/Area Foreman The report will identify: • Nature and Cause of emergency • Statistics pertaining to emergency (i.e. damage, injuries, etc.) • Effectiveness of Company Emergency Response Personnel • Corrective Measures taken to prevent recurrence of similar emergency at this location (considering applicability to other locations) VIII. H 2 S CONTINGENCY PLAN SCOPE The purpose of this Section is to provide an organized plan of action to protect the general public and employees in the event of an accidental release of a potentially hazardous volume of hydrogen sulfide (H2S), or other toxic/hazardous gas. PRESENTLY NO H2S LOCATIONS UNDER OPERATION IN COLORADO, UTAH LOCATION INFORMATION PREVAILING WIND - LINES UNDER DOT REGULATION - STATE/FEDERAL LEASES - FIELD FUEL- OTHER- SEE SECTION IX FOR AREA SPECIFIC INFORMATION. RESPONDING TO LEAKS CONTAINING H2S 1. A leak may be detected and/or reported by various individuals/the public, BBC personnel, public safety officials etc. 2. Once a leak has been determined to be from BBC's facilities, the following information shall be obtained and relayed to the SuperintendenUArea Foreman/Designee: a. Type of leak. b. Personal injuries. c. Location and magnitude of leak. d. Direction and velocity of the wind. e. Residents, businesses, and highways located downwind of the leak. f. Your action and/or advice concerning evacuation of nearby residents and businesses or establishing roadblocks. g. Action being taken to alleviate the situation. h. Time emergency occurred, or was reported. i. Estimate of damage to date and potential future damage. 3. The SuperintendenUArea Foreman or designee will be in charge of the actual on-site operations. 4. SuperintendenUArea Foreman or designee will assign someone to monitor company radio frequency. Carry a 2-way, or bring a company truck with a radio as close as possible and maintain communications with response personnel. 5. The ranking BBC employee will be in charge of all actions until the SuperintendenUArea Foreman or designee arrives. Protective equipment should be used as appropriate. 6. Operating personnel will attempt to determine seriousness of situation, and a. Notify immediately other personnel in area. b. Gather all personnel, customers and visitors at the rendezvous point, depending on release location. c. Recall employees if the emergency happens off-hours. (Numbers listed in the Call Lists section of this manual.) d. Contact EH&S personnel. e. Maintain a log of all contacts with residents, regulatory and law enforcement agencies, other operators, etc. f. Determine whether assistance is needed from public safety officials. 7. Operating personnel should attempt (from a safe area) to shut in leak and be alert for chemical and/or liquid hydrocarbon run-off. If chemicals are involved in a fire, think of the consequences before you use water on the fire. It may be better to contain the fire and let the chemicals incinerate. Close off the area. If you do not have the necessary equipment, heavy equipment operators are listed in the Contractor Services and Equipment listing in the Appendix Section. 8. If injuries have been sustained, start first aid procedures and call for ambulance service if needed, organize search and rescue if anyone is still unaccounted for. 9. If gas escape cannot be safely shut-in, stopped, etc., and presents hazard to residents, personnel or property, the following steps should be taken: a. Determine if the sour gas being released should be ignited to protect residents. b. Initiate Evacuation Procedure. EVACUATION PROCEDURE 1. Review with personnel on scene what measures are being taken for evacuation and the urgency for immediate action. 2. Alert necessary personnel to activate all, or a portion of the Sections of this Plan. FACILITY Field Technician/Pumper SuperintendenUArea Foreman Operations/Area Manager Environmental/Safety Specialist Contract Help Teams for: Notifying residents and school bus system Evacuating Residents Establishing and manning roadblocks Persons to: Man briefing area Man safe area Monitor H2S concentrations (if gas is sour) Maintain log of events and action taken 3. Locate area of release on map which shows location of lines, roads, dwelling, etc. 4. Determine best estimate of: a. Volume being released. b. H2S concentration. c. Wind velocity and direction. d. Future volumes and H2S concentrations. 5. Identify residents that should be notified and/or evacuated immediately. 6. Instruct resident notification team to make necessary contacts. 7. Advise the evacuation team of those residents that could not be contacted via telephone, or those that will need assistance. 8. Stay in contact with resident notification and evacuation teams as to whom has been notified, evacuated, etc., making sure a log, of those contacted, is maintained.

(NSI) to perform an analysis of the noise expected to be generated by the proposed compressor station and mitigation efforts that may be required so that the station will meet the applicable COGCC standards. Per COGCC Rule 802.c.(1), noise measurements shall be measured at 350 feet or the property line, whichever is greater. Therefore, NSI was asked to analyze the expected noise levels at the property lines closest to the proposed facility -594 feet east and 607 feet south. In addition, the expected noise levels at the four residences closest to the proposed facility were evaluated to ensure that noise levels at those residences would meet the applicable standards. For noise levels on the db(A) scale, the residential standard from COGCC Rule 802.c. was used as the applicable regulatory standard. For noise levels on the db(C) scale, the COGCC standard of 65 db(C) at the residences was used for this evaluation. Initially, NSI analyzed the noise level expected to result from this facility with no building over the compressors and also with a bare (uninsulated) building. Noise levels under these scenarios were predicted for each of the six receptor locations. Because the predicted noise levels exceeded the applicable standards, NSI then analyzed a series of mitigation measures that could be employed to meet the standards. These analyses are provided in Tables 12-17 in the report included in the Impact Analysis Tab. BBC will employ all of these mitigation measures at this facility. Tables 12-13 indicate that the db(A) noise levels at the property line would meet the COGCC residential standard, and Tables 14-17 indicate that the db(C) levels at each of the residences would meet the COGCC standard.
