PARACHUTE STAGING AREA Supplemental Impact Statement A Section 5.03 Review Standards 2) Street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe access to the use shall either be in place or shall be constructed in conjunction with the proposed use; EnCana has determined and agreed to limit the proposed use of the staging area to the North Parachute Operations only. The site will not be utilized to store or maintain rigs associated with drilling operations within the South Parachute Operations Area. As a result, rig and associated equipment moves from EnCana operations to the north will only impact the length of County Road 215 from the access into the proposed site and to the point where County Road 215 terminates at EnCana Property to the north. No truck traffic, associated with the proposed site, will need to travel along the section of County Road 215 south of the access to the site, nor will rig haul traffic from the north continue to impact the Town of Parachute or Interstate 70. During maintenance of the drilling rigs and equipment, while stored in the proposed staging area, service vehicles will need to access the site. These service vehicles will range in description and size from 1 ton pickups to 2'/z ton trucks. It is anticipated that one each of this type of vehicles will need to access the site on a daily basis and will be limited to the duration of which the rig and equipment is being stored on site. B. Section 5.03.07 Industrial Operations 1) a) Existing lawful use of water through depletion or pollution of surface run- off, stream flow or ground water; EnCana has contracted Hawworth-Pawlak Geotechnical to calculate the drainage requirement for the site. The actual size of the proposed retention pond exceeds the calculated area required. See attached Mohave Engineering Associates drawings which depict the proposed drainage plan. See attached Spill Prevention Control and Countermeasure (SPCC) plan b) Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or vibration, or other emanations; During maintenance operations on the rigs and equipment, EnCana anticipates an average of one 1 ton pickup and one 2 '/2 ton truck with an average crew size of 6 personnel will be required to access the staging area on a daily basis. The duration of the visits will be determined by the extent and nature of the repairs and maintenance required. Once repairs and maintenance are completed, these vehicles will no longer access the site. c) Impacts on wildlife and domestic animals through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions; See attached Westwater Engineering Plan d) Affirmatively show the impacts of truck and automobile traffic to and from such uses and their impacts to areas in theCounty; As Mentioned above, EnCana has determined and agreed to limit the proposed use of the staging area to the North Parachute Operations only. The site will not be utilized to store or maintain rigs associated with drilling operations within the South Parachute Operations Area. As a result, rig and associated equipment moves from EnCana operations to the north will only impact the length of County Road 215 from the access into the proposed site and to the point where County Road 215 terminates at EnCana Property to the north. No truck traffic, associated with the proposed site, will need to travel along the section of County Road 215 south of the access to the site, nor will rig haul traffic from the north continue to impact the Town of Parachute or Interstate 70. During maintenance of the drilling rigs and equipment, while stored in the proposed staging area, service vehicles will need to access the site. These service vehicles will range in description and size from 1 ton pickups to 2 1/2 ton trucks. It is anticipated that one each of this type of vehicles will need to access the site on a daily basis and will be limited to the duration of which the rig and equipment is being stored on site. Landscaping Plan Due to the location of the proposed site, within sight distance of a public road, EnCana proposes to construct an 8 ft high chain-link fence equipped with privacy slats on the upper tier of the property along the east side of the site. The proposed staging area is to be located at a lower elevation as compared to the easterly portion of the property. With the construction of the privacy fence on the higher elevation, visual impacts due to the site will be substantially minimized or eliminated for local traffic along County Road 215. Privacy fencing or additional landscaping along the north, west and south boundaries should not be required due to the industrial nature of the adjacent properties. Reclamation Plan The expected life of the Parachute Staging Area will be the same as the duration of EnCana Oil & Gas operations in the North Parachute area. Reclamation will consist of the following: • immediate re -seeding of all disturbed areas outside of the fenced site caused by construction of the site. • Removal of all fencing • Removal of surface pipe racks and equipment • Removal of rock and gravel materials • Restoration and re -contouring of grade to approximately original condition • Replacement of stockpiled topsoil • Reseeding with certified, weed -free seed mixtures to match surrounding vegetation (see Westwater proposed seed mix) • Continued monitoring of re -vegetation growth. Re-application of seed as required. • Compliance with all prevailing Garfield County regulations and conditions governing final reclamation Prior to abandonment of the staging area, EnCana would contact the Garfield County Planning Director to arrange for a meeting and joint inspection of the site. This meeting and inspection would take place a minimum of 30 days prior to abandonment and would be held so that an agreement on an acceptable abandonment plan can be reached An Abandonment and Reclamation Plan would be developed to address the bullet points listed above:.

(USA) (EnCana) Parachute Laydown Yard (PLY). The site is located west of County Road 215, Parachute Creek Road at Wheeler Gulch Road (see Figure 1). The inspections was conducted for the purpose of a wildlife assessment and management plan. Factors considered include existing land management practices, absence or presence of suitable wildlife habitat, direct or indirect evidence of wildlife use, and existing and potential natural vegetation community. Landscape Setting The PLY is on the first terrace above the floodplain of Parachute Creek. It is east of Parachute Creek in an industrial setting situated between Williams, Inc. compressor plant and American Soda. Terrain is gently sloping to nearly flat at the entrance to the yard. The property has a westerly aspect. The Colorado Division of Wildlife (DOW) requested approximately 80 acres of vacant land adjacent to the PLY be set aside as wildlife habitat. EnCana and Williams, Inc. voluntarily agreed and contributed approximately 40 acres each. The purpose of the set aside is to provide a corridor for wildlife movement between. Wheeler Gulch to the east and Riley Gulch to the west across the Parachute Creek Valley. According to District Wildlife Manager JT Romatzke (2006), the corridor would be more effective if the vegetation community had more structure or layers than merely the surface herbaceous layer and a few decadent shrubs currently present. Potential Wildlife Occurrence Due to the relation to the current built environment and poor vegetation component, a low diversity of wildlife is expected to be observed passing over, nearby, or through the site seasonally. The wildlife set aside corridor is not as effective as it could be due to extreme sight distances between between shrub copses. Species or sign of their presence observed directly on the site are shown in bold type in Table 1. The other species shown in Table 1 reasonably could be expected to be observed at some time during the year from on or near the site. The adjacency of the PLY to Parachute Creek and riparian vegetation community increases the diversity of potential wildlife use. Few of the listed species are observed year round, i.e. presence is seasonal. Ee 1.

When found in Garfield County in similar vegetation communities with normal structural diversity. Discussion Importance of vegetative structure was evident at the time of inspection. The neo -tropical birds observed as noted in bold in Table 1 were all using greasewood. The site is poor wildlife habitat due to lack of vegetation community structure, past soils disturbances, high levels of human activity in combination with sight distances of 400 meters or more, and domestic livestock grazing. To be more effective for wildlife, the corridor would benefit from establishment of vegetation communities with multiple structural levels. According to the Natural Resources Conservation Service, U.S. Dept. of Agriculture, 2006, potential natural vegetation for Arvada loam soil on the east, north and south side of the PLY include alkalai sacaton (Sporobolus airoides), inland saltgrass (Distichlis spicata), western wheatgrass (Pascopyrum smilhii), bottlebrush squirreltail (Sitanion hystrix), Gardner's saltbush (Atriplex gardneri), greasewood (Sarcobatus vermicttlatus), and winterfat (Krascheninnikovia lanata). A vegetation community composed of these species would contain multiple structural layers resulting in a complex more suitable to providing multiple life stage functions for resident wildlife. Actual vegetation complexes observed include a few greasewood, 0.5-1.5 m. in height, robust, desert seep willow (Saueda moquinii), Russian thistle (Salsola tragus), and pepperweed (Lepidium spp.) which dominate the alkaline halaquepts soil. Vegetation present on the majority of the site includes alkalai sacaton, bottlebrush squirreltail, a few rabbitbrush (Ericameria spp.) and a wheatgrass, probably tall wheatgrass (Elymus elongalus). Cheatgrass (Bromus tectorum) and halogeton (Halogeton glomeratus) are also present but in relatively low density. Within 250 meters was a copse of rabbitbrush more suitable to providing the type of cover providing more function of greater value than that currently available. Vegetation conformation, hoof prints, and fecal remains exhibited evidence of heavy grazing pressure from cattle with less than 25% annual growth remaining on most plants in the study area. Native vegetation canopy varied between 1-15% where it was found. Wildlife Mitigation Improvement of undisturbed adjacent land to encourage vegetative type conversion to shrublands would greatly increase the function and value of the set aside. Greater than 90% of the surrounding land possesses only the herbaceous layer of vegetation. Methods to improve the vegetation community include: • removing or reductin domestic livestock grazing, • controlling and eliminating noxious and invasive vegetation, planting aggressive, native grasses, • creating shrub copses by seeding or planting live plant materials in locations to reduce sight distances between copses and other cover, • selectively locating future berms or soil stockpiles to decrease sight distances, • removing all unnecessary fences, • and ensuring necessary fences are wildlife friendly. This list is not meant to be exhaustive. Other options to improve wildlife value may emerge. Those listed above are the most obvious for direct improvement of wildlife function and value. Best Management Practices Minimize the footprint of temporary disturbances and reduce to the minimum level possible all soil disturbing activities. Construction vehicles and staging should be done in a manner to reduce the footprint of new disturbance during construction. Re -seeding Temporary disturbances on EnCana property should be re -seeded with the seed recipe in the PLY Integrated Vegetation and Noxious Weed Management Plan. Fence Removal Some wildlife un -friendly fences are located near the PLY. Removal of all unnecessary fencing in the vicinity will improve the over all value to wildlife as the vegetation community develops more functions and greater values with subsequent increases in levels of wildlife use and diversity.

SPCC Plan Parachute Staging Area November 2006 8of19 2.5 Contact List and Phone Numbers (112.7 (a)(3-5)) Lists of contact names and phone numbers for EnCana Oil & Gas (USA) Inc. personnel, company approved cleanup contractors, and federal and state agencies are contained in Appendix A. Also included in Appendix A are forms to be used for organizing release notification infonnation and the submission of required information to the EPA Regional Administrator for qualified discharges. 2.6 Spill Prediction and Control (40 CFR 112.7 (a) and (b)) Equipment temporarily staged in the Parachute Staging Area that may have the potential to accidentally release oil are addressed in Appendix F. However, purpose of the staging facility is to temporarily stage drilling, completion, work -over rigs and associated containers and equipment, which will result in equipment moving in and out of the facility. Given this activity, the list of staged equipment that may have potential to accidentally release oil for a specific point in time (date of this plan) may not be complete. The reasonably expected modes of major failure or accident for which oil could be released from an active on -shore facility are as follows: A. Bulk Storage Tank Leak or Failure I. Failure Modes: Corrosion, vandalism, lightening strikes, valve or piping failure, overfilling (i.e., human error). 11. Rate of Flow: Variable, depending upon the type, size and location of the tank failure. The ambient temperature at the time of the release may affect the viscosity of the oil and thereby impact the rate of release. Flow rates for corrosion failure are typicaIIy low. Lightning strikes may result in a release that is essentially instantaneous. M. Discharge Quantity: Total quantity discharged would not exceed the working capacity of the largest tank (estimated 500 bbls) IV. Preventative Measures: Storage tanks are generally constructed in accordance with API industry standards. Materials used in constructing the tanks are compatible with the substances stored. Where practicable, earthen berms/dikes or other diversionary structures are utilized to control any released fluids. Tanks are appropriately sized to minimize the risk of overfilling. B. Tanker Truck Loading and Unloading Operations 1. Failure Modes: Piping or valve failure, tank failure, overflow, and human error. II. Rate of Flow: Variable depending upon the type, size and exact location of the failure, and the amount of oil in the tanker truck and storage tank. The ambient temperature at the time of the release may affect the viscosity of the oil and thereby impact the rate of flow. Flow rates resulting from piping and EnCana. Oil & Gas (USA), Inc. SPCC Plan Parachute Staging Area November 2006 9of19 valve failures can range from 1 gallon per hour up to 400 barrels per hour. The flow rate for tank truck overflows typically will not exceed 5 to 10 barrels per minute. Tank failures may result in releases that are essentially instantaneous. III. Discharge Quantity: Potential discharge quantity is variable depending upon the type and location of the failure. The total quantity discharged would not exceed the working capacity of the largest tank (estimated 500 bbls). IV Preventative Measures: Tanker truck loading and unloading operations are conducted in accordance with United States Department of Transportation regulations (49 CFR 177). All loading operations are attended by the truck driver. No smoking or open flames are allowed in the vicinity of the storage tanks and loading area. Wheel chocks are placed at the wheel nearest the truck loading connection to reduce the risk of the truck movement during loading operations. Following the completion of loading operations, the transfer line is disconnected and all valves and outlets on the tanker truck and the storage tank are visually inspected for leakage prior to vehicle departure. C. Piping Failure I. Failure Modes: Both aboveground and buried pipelines may rupture or corrode and leak. Associated flanges, screwed connections, valves and gauges are also subject to corrosion and may fail or leak. II. Rate of Flow: Variable, depending on the size and location of the piping related failure. The maximum potential rate of flow is not expected to exceed the oil process rates as listed in Appendix F. III. Discharge Quantity: Potential discharge quantity is variable depending upon the type and extent of the failure and the length of time that the failure went undetected. IV. Prevention Measures: Personnel routinely perform visual inspections of aboveground piping and buried flowline right- of-ways to detect failures. As warranted by soil conditions, corrosion protection is provided for buried pipelines. 2.7 Oil. Spill Contingency Plan and Commitment of Manpower (40 CFR112.7 (d)(1) & (2)) EnCana Oil & Gas (USA) Inc. maintains a strong contingency plan for oil spills and a written commitment of manpower follows. EnCana Oil & Gas (USA) Inc. is committed to a strong antipollution and spill prevention program. We are committed to designing and operating our facilities in a manner that will minimize the size and occurrence of spills. We are committed to a strong, pro -active training and inspection program that will insure that our facilities are operated and maintained in a manner that will prevent or minimize the occurrence of spills. In the event of a spill, EnCana Oil & Gas (USA) Inc. will commit the manpower, equipment and materials necessary to ensure that the clean up occurs in the shortest practical time while minimizing environmental damage and maximizing product recovery. EnCana Oil & Gas (USA), Inc. SPCC Plan Parachute Staging Area November 2006 lOof 19 2.8 Discharge Countermeasures and Methods of Disposal (40 CFR 112.7 (a)(3)(iv)&(v)) In the event of an accidental release, EnCana Oil & Gas (USA) Inc. personnel will promptly initiate recovery actions as appropriate. Levels of Response Major Releases: Major releases are defined as: 1) Spills of crude oil, condensate, or saltwater greater than 5 bbls, or 2) Spills of refined crude oil products, including but not limited to, gasoline, diesel fuel, aviation fuel, asphalt, road oil, kerosene, fuel oil, and derivative of mineral, animal or vegetable oils, or 3) Any volume of oil which results in a fire, will reach a water course, or may with reasonable probability endanger public health or result in substantial damage to property or the environment. Major releases will be handled under the direction of EnCana Oil & Gas (USA) Inc. personnel. Response contractors listed in Appendix A will be utilized as necessary to complete the clean up. If oil should threaten surface waters, the company contingency plan will be implemented. Containment structures would be constructed and booms would be deployed as needed to protect waterways. Minor Releases: Releases not classified as major shall be reported internally to the appropriate supervisor on an incident report. Product Recovery and Handling Spills onto Soil Mobile oil spills should be contained as soon as possible by the construction of earthen dams or by the placement of mechanical barriers. Free oil may be removed from the ground by the use of a vacuum truck. Sumps or trenches may be dug to intercept or drain free oil. Remaining free oil may be removed from the ground by the use of oil -absorbent materials. When all free oil has been removed, the affected soil containing over 1.0% total petroleum hydrocarbon (TPH) by weight should be delineated, both vertically and horizontally. All soil containing over 1.0% TPH should then be excavated by backhoe or similar appropriate equipment for remediation or disposal. To prevent stone water contamination, all impacted soils containing in excess of 1.0% TPH should placed in an approved disposal site or in a secure interim storage location for future remediation or disposal, unless more immediate on-site techniques and be implemented. Placing the impacted soil on a sheet of visquene (plastic) and providing appropriate cover, diking, or stone water diversions, is acceptable. A final cleanup level of 1.0% TPH should be achieved as soon as practicable. Several methods are acceptable for the cleanup of oil contaminated soil; regulatory agencies may specify which methods are appropriate. Spills onto Water Oil spills onto surface waters must be cleaned up to the satisfaction of the landowners and regulatory agencies. The spill should be contained as soon as possible by the use of floating booms or other mechanical barriers. Free oil may be removed from the water by the use of a vacuum truck or by oil -skimming equipment. Remaining free oil may be removed from the water by the use of oil -absorbent materials such as spray -sorb. Oil -absorbent materials may also be used to remove oil that has accumulated on shoreline soils, rocks and vegetation. Oil EnCana Oil & Gas (USA), Inc. SPCC Plan Parachute Staging Area November 2006 11 of 19 contaminated shoreline materials may require removal to a suitable treatment site for cleanup as described above. 2.10 Regulatory Conformance The subject property is not subject to any state regulated discharge prevention and containment requirements beyond those specified by federal regulation. 2.11 Regulatory Exclusions The subject property is classified as onshore non -production facility.

The inspection conducted for the purpose of an integrated vegetation and noxious weed management plan. Factors considered include soil type and texture, existing land management practices, absence or presence of listed noxious weeds and likely potential natural vegetation community. Landscape Setting The EnCana Oil & Gas, Inc. (USA) (EnCana) Parachute Laydown Yard (PLY) is on the first terrace above the floodplain of Parachute Creek. It is east of Parachute Creek in an industrial setting situated between Williams, Inc. compressor plant and American Soda. Approximately 80 acres of vacant land adjacent to the PLY has been set aside as wildlife habitat by EnCana and Williams, Inc. Terrain is gently sloping to nearly flat at the entrance to the yard. The property has a westerly aspect. Soils are primarily halaquepts, a soil with salic horizon, and Arvada loam (MRCS, 2006b). According to the Natural Resources Conservation Service, U.S. Dept. of Agriculture, 2006b, potential natural vegetation for Arvada loam includes alkalai sacaton (Sporobolus airoides), inland saltgrass (Distichlis spicata), western wheatgrass (Pascopyrum smithii), bottlebrush squirreltail (Sitanion hystrix), Gardner's saltbush (Atriplex gardneri), greasewood (Sarcobatus vermiculatus), and winterfat (Krascheninnikovia lanata). No ecological site or rangeland information is available from the USDA for halaquepts soils which are the white -glazed, highly - saline clay soils commonly found in low-lying areas in or near Wasatch Badlands. A few individual saltcedar plants, greasewood, 0.5-1.5 m. in height, robust, desert seep willow (Saueda moquinii), Russian thistle (Salsola tragus), and pepperweed (Lepidium spp.) dominate the alkaline halaquepts soil. Vegetation present on the Arvada loam includes alkalai sacaton, bottlebrush squirreltail, rabbitbrush (Ericameria spp.) and a wheatgrass, probably tall wheatgrass (Elymus elongatus). Cheatgrass (Bromus tectorum) and halogeton (Halogeton glomeratus) are also present but in relatively low density. The vegetation community of the Arvada loam exhibited heavy grazing pressure from cattle with less than 25% of vegetative canopy remaining on most plants in the study area. Native vegetation canopy varied between 1-15%. Wel:tWater Engineering iuc LayiioWn Yard IVNWMP Page 2 of 8 Current Amount of Infested Land Needing Treatment The site is free of listed noxious weed species Garfield County regulates. A couple of meters west of the proposed entrance are saltcedar which have regenerated from previously treated plants. There were stems of dead saltcedar in the immediate area. Saltcedar plants numbered less than 20 in the immediate vicinity and less than l % canopy in the floodplain riparian area west of the site. Table 1.

Seedlings and sprouts easily hand -pulled when the oil is moist. Once established, cut -stump herbicide treatment most effective. Photo 1. Mature Saltcedar. Adams County. Extension Service.

Pipe Laydown Yard IVNWMP Page 3 of 8 A species found on the State of Colorado "C" list at $CCR 1203-19, Bromus tectorum, cheatgrass, is found throughout the site in low density (< 20%). As mentioned previously, clasping pepperweed and halogeton are also present but not regulated. Recommended Treatment Herbicides should not necessarily always be the first treatment of choice when other methods can be effectively employed. In this, an industrial complex, it is not acceptable to have vegetation component subject to wildfire. Therefore, the recommended treatment for the interior of the PLY is a selective soil sterilant. This should be a soil sterilant which will not drift outside the boundaries if used according to label instructions, e.g,, Journey* or Sahara DG®. Some products are reputed to be selective to undesirable plants while allowing desirable plants to flourish even if their roots come into contact with the active ingredient of the herbicide. Due to the complexity and inherent danger if improperly used or applied, it is recommended a certified commercial applicator be retained to choose the most appropriate product(s) and make the application. Best Management Practices In all cases temporary disturbance should be kept to an absolute minimum. All temporary disturbances should be immediately replanted with the recommended mix in the re -vegetation section. Herbicides: For control of saltcedar plants, cut and immediately spray stump during the growing season. Many over-the-counter products are available which are effective. The most commonly used active ingredient is triclopyr, most commonly sold under the trade name Garton 40 but also available in other products. It is recommended a commercial herbicide applicator be retained to treat the PLY during soil and earth work activities. Incorporating appropriate herbicides in the upper 2 -inch soil horizon instead of just the surface may increase the effectiveness of the product. Appropriate selection and timing of application by a certified applicator can make a difference in the success of control. Grazing: There is currently heavy grazing by cattle on the site and adjacent to it. Grazing should be controlled in a manner to enhance the vegetative community. At the present level observed on the site, native vegetation will be suppressed and the opportunity for invasive noxious weeds is greater than it could be. It is recommended grazing be removed on adjoining EnCana, Williams, Inc. and American Soda vacant Iands. WWest'Natef Ytor'i d'f F, is Lnvcluvv `r.rr.r lVfVk'JILil' Mechanical: Monitoring for establishment of noxious weeds in a timely way can make control a matter of hand -pulling new seedling saltcedar. Alternative Methods: No noxious weeds with potential for biological control are found near the site in sufficient density to host a colony of parasitic insects. It is not possible to control a few plants with insects. Removing grazing of domestic livestock could be considered, in this case, an alternative treatment and would improve the quality and quanity of rangeland plants. Revegetation The seed mix was developed for EnCana by WestWater in the "EnCana North Parachute (NPR) Reclamation Plan", March of 2006 and is repeated herein for convenience and consistency for EnCana projects on or near NPR.

Seeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill. Seed should be bagged separately so each size group of seed can be metered at the appropriate rate. Applying a half pound over an acre with a species such as scarlet globemallow is difficult and may require use of wheat bran or rice hulls or some other adjuvant to assist metering the small seeds at the appropriate rate. Westwater Engineering Pipe L, y ci °fri (di d IVN)AffVit Page 5 of 8 Alternative seeding methods include but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re - harrow, preferably at a 90 degree angle to the first harrow, • hydro -seeding (most economical in terms of seed cost), and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control and then coming back to plant live; containerized woody species has been the most cost effective method for establishing the woody species component of the plant community. Upon completion of re -seeding, shrub species adapted to the site from the above table could be planted with live plants to increase compatibility with adjacent wildlife habitat. Best results can be expected from use of live, containerized plant materials. These species are available in containers of 10 in.3, I quart, 1 gallon and 5 gallon containers and are available locally from Rocky Mountain Native Plants, Silt, Palisade Gardens, Palisade, CO., or Dry West Nursery, Hotchkiss, CO. Other local vendors may have native species depending on availability at time of need. Number of plants needed is based on the mature size of the species and, to a lesser extent, size of live plant material at time of planting. Application of commercial arbuscular mycorrhizal fungi (AMF) compounds to roots of live shrubs and trees has been shown to increase survival where native AMF may be absent due to disturbance of native soils horizons. Temporary, supplemental irrigation for approximately 3 years after planting will greatly increase successful establishment of shrubs and forbs. Once established, the recommended species will not need supplemental irrigation. Life Cycle and Management Calendar Due to the absence of regulated weeds, the annual calendar for this site is relatively simple. 'Cagle 3.

It is recommended grazing be removed on adjoining EnCana, Williams, Inc. and American Soda vacant lands. WeG tWater Engineering Pipe paydown Yard IVNWMP Page 4 of 8 • • Mechanical: Monitoring for establishment of noxious weeds in a timely way can make control a matter of hand -pulling new seedling saltcellar. Alternative Methods: No noxious weeds with potential for biological control are found near the site in sufficient density to host a colony of parasitic insects. It is not possible to control a few plants with insects. Removing grazing of domestic livestock could be considered, in this case, an alternative treatment and would improve the quality and quanity of rangeland plants. Revegetation The seed mix was developed for EnCana by WestWater in the "EnCana North Parachute (NPR) Reclamation Plan", March of 2006 and is repeated herein for convenience and consistency for EnCana projects on or near NPR.

Seeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill. Seed should be bagged separately so each size group of seed can be metered at the appropriate rate. Applying a half pound over an acre with a species such as scarlet globemallow is difficult and may require use of wheat bran or rice hulls or some other adjuvant to assist metering the small seeds at the appropriate rate. WestWater Engineering Pipe Laydown Yard IVNWMP Page 5 of 8 • • Alternative seeding methods include but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re - harrow, preferably at a 90 degree angle to the first harrow, • hydro -seeding (frost economical in terms of seed cost), and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control and then coming back to plant live: containerized woody species has been the most cost effective method for establishing the woody species component of the plant community. Upon completion of re -seeding, shrub species adapted to the site from the above table could be planted with live plants to increase compatibility with adjacent wildlife habitat. Best results can be expected from use of live, containerized plant materials. These species are available in containers of 10 in.3, I quart, 1 gallon and 5 gallon containers and are available locally from Rocky Mountain Native Plants, Silt, Palisade Gardens, Palisade, CO., or Dry West Nursery, Hotchkiss, CO. Other local vendors may have native species depending on availability at time of need. Number of plants needed is based on the mature size of the species and, to a lesser extent, size of live plant material at time of planting. Application of commercial arbuscular mycorrhizal fungi (AMF) compounds to roots of live shrubs and trees has been shown to increase survival where native AMF may be absent due to disturbance of native soils horizons. Temporary, supplemental irrigation for approximately 3 years after planting will greatly increase successful establishment of shrubs and forbs. Once established, the recommended species will not need supplemental irrigation. Life Cycle and Management Calendar Due to the absence of regulated weeds, the annual calendar for this site is relatively simple. Table 3.

(EnCana) representatives to discharges or spills of exploration and production (E&P) related materials within the Town of Parachute Watershed District (Watershed). It is not the intent of this procedure to establish liability of the responsible party for a discharge or spill within the Watershed. The procedure details the notification and response procedures by which any such E&P related discharge or spill shall be handled. Figure 1 has been prepared to illustrate the watershed boundary and the coverage of this procedure. 1.2 Applicability This procedure is applicable to all facilities, including but not limited to, pipelines, stationary vessels, and all transports that may contain E&P related materials that may cause an adverse environmental impact to the Watershed. A spill or unintentional release into the environment may give rise to a variety of reporting requirements. Reporting requirements will vary depending upon what is spilled, the amount spilled and the time, location, and effects of the spill. This procedure provides guidance for fulfilling the requirements of EnCana or their designated representative and does not fulfill any Federal, State or local reporting requirements. 1.3 Limitations To develop this guidance, Wagon Wheel Consulting (WWC) was required to formulate the procedures based on the best information available during the period in which this document was developed. Information from currently promulgated and, in some cases, interim regulations were used. Additionally, third party documents and statements were used, the accuracy of which cannot be warranted. Professional judgment was exercised in gathering and analyzing the information obtained. Caution should be exercised in using this document because of the additional Federal, State, and local reporting requirernents that may be applicable and are not contained as part of this document. WWC cannot completely eliminate the possibility of obtaining partially imprecise or incomplete information. This document should be periodically reviewed and updated. • 1.4 Procedure Organization This procedure is organized into three sections including this introduction. Section 2.0 presents the response organization of EnCana. The initial response actions to a spill or release are presented in Section 3.0 1-2 • Figure 1-3 • SECTION 2.0 RESPONSE ORGANIZATION AND COORDINATION 2.1 EnCana Organization The reporting of spills is the responsibility of the initial responder. Awareness of this procedure by any potential initial responder is critical to ensure the proper implementation of this procedure. A Spill contingency Plan Decision Tree has been prepared and is included as Attachment A. The Spill Contingency Plan Decision Tree should be used by the initial responder and subsequent responders to properly assess a spill event. Immediate access to the Emergency Call Out Contact List must be made available to any and all appropriate parties including, but not limited to, all applicable EnCana personnel, contractors, subcontractors, and applicable Town of Parachute representatives. The Emergency Call Out Contact List has been incorporated into this document as Attachment B. 2.2 Response Training All applicable response personnel of EnCana, and selected response contractors will be trained in accordance with the provisions of this procedure. On-site annual refresher training will occur with all response personnel. Response procedures and materials will be evaluated annually and any changes incorporated within a revised Spill Response and Reporting Procedures document. Revised procedures will be distributed to all applicable personnel, contractors and Town of Parachute representatives. Additional training of response personnel may apply pursuant OSHA Hazardous Waste Operations and Emergency Response Standard (29 CFR 1910.120). Discretion and responsibility of additional OSHA training are determined by the responders company policy. 2.3 Documentation Appropriate verbal and/or written notification should be made based upon the situation and reporting requirements. Corrective action and/or countermeasures should be immediately addressed by on-site personnel. A written record of all pertinent information given to each applicable Agency and the Agency's response is to be retained by the environmental manager or designated representative of the responsible party. The information should include: M Name, address, and location of the facility; • Name, title and phone number of the person reporting the spill, the responsible party and the contact person; 2-1 • • • Spill location within the facility andlor outside of the facility (section, township and range); • Material spilled or released • Volume! quantity of the spill; • Complete description of containment and remedial efforts, including ultimate disposal or treatment alternatives; • Bodies of water involved, the extent of actual and potential pollution or threat to surface water; • A chronology of all occurred events including; a complete description of circumstances causing the release or spill, actions taken and explanations; • Whether or not the spill or release consisted of a listed hazardous waste andlor a characteristic hazardous waste, as defined in 40 CFR Part 261; • A description and estimate of any third party damages; • Procedures. Methods and precautions instituted to prevent a similar reoccurrence; • Other appropriate information for the particular spill or release. A sample Spill Response Notification Form has been provided in Appendix C. 2-2 • • SECTION 3.0 INITAIL RESPONSE ACTIONS There are a number of measures which can be taken to minimize the threat to human health and the environment when a spill of oil or hazardous substances is first detected. The following measures should be considered as general guidelines and may not apply to all circumstances. 3.1 Initial Contact If a spill endangers the public health or welfare though traffic hazard, explosion, fire, noxious gas, water contamination or other means, immediately refer to the Emergency CaII Out Contact List for notifications. When making these initial notifications, personnel should attempt to provide, at a minimum, the following information: • Name of caller and call-back number; • The exact location and nature of the incident; • The extent of personal injuries and damage; and • The material involved and any hazardous information. 3.2 Human Safety Only trained personnel should approach a fire or spill. Individuals who first identify a spill should: • Avoid direct contact with the spilled material; • Avoid inhalation of any gases, fumes, vapors and smoke; • Move and keep people away from the incident scene. Contact law enforcement authorities for assistance, if necessary; • Attempts to determine and remove all ignition sources without unnecessarily endangering life; • Contact the designated first contacts or alternates as illustrated in the Emergency Call Out Contact List. 3.3 Substance Identification One of the most important aspects of the initial response activities is the identification of the substance involved. Members of the response team should make this assessment with the assistance of the responsible party or operations personnel. Under no circumstances should substance identification be attempted without adequate personal protective equipment and without exercising extreme caution.. 3-1 • • 3.4 Mitigation Measures Initial response actions should include actions by trained personnel to shut off the source of a spill or discharge. and to contain and mitigate the consequences of the spill. Any spill with the potential to impact Parachute Creek, upgradient of the Town of Parachute Municipal water supply intake, will require trained personnel to mitigate any impact to the Town of Parachute water supply. Mitigation measures may include manually dosing the Town of Parachute intake upgradient of the gauging station or using response materials to prevent any contaminants from entering the intake. 3.4.1 Containment of Spills on Land Natural avenues of migration such as streams, waterways, ditches, and natural gullies should be followed on foot to determine extent of migration and impacted avenues. Containment facilities should be constructed if any impacts are identified. A field - constructed type of containment device is an earthen dam. A dam can be made by piling up earth with a bulldozer, backhoe, or other earth -moving equipment. Natural dry ditches can be blocked with compacted earth (dam) and used as a storage pond to which a spill can be directed. Spills on paved or hard (frozen) surfaces can be deflected into such ditches or ponds with sandbag barriers. The dams act to stop the uncontrolled flow of product and create a pool for easier recovery. In order to prevent the infiltration of the released product into the subsurface or leaching into the ground water, plastic sheeting or other non -porous material may be used to line the dam. 3.4/ Containment of Spills in Shallow Water Spill booms, straw fences, and or flume dams are types of spill containment devices that can be used to contain spills in shallow waters. The type of containment selected will depend on the site-specific conditions encountered and materials readily available. Spill booms may be used if the water is deep enough to allow free flow of water under the boom. If used, the booms will be set at an angel to the flow of the stream and. skimmer pits should be dug to catch the containment as it moves downstream. A straw fence may be constructed using chicken wire or snow fence staked at an angel to the flow of the stream. Straw bales should be broken into pieces about two -feet square by eight to ten -inches thick and stacked vertically. This provides protection for a long time, prevents loose impacted straw from working downstream, and facilitates changing saturated straw for fresh straw. A straw fence should be built at an angel to the shore, with a pit or sump at the shore to skim the oil. 3-2 • • An underflow dam (or flume dam) may be built to contain the product or to protect against the further spread of the spill in the event of rain. The dam diverts the water though a conduit of pipe (or pipes) placed roughly parallel to the direction of the water flow. The pipes are installed so that the upstream end is lower than the downstream end. The stream is blocked by bulldozing earth across the pipes and packing the dirt down. The pipes allow water to pass through the flume, but retain the product behind the dam. 3.4.3 Containment of Spins in Deep Water A containment boom is the best method of confining a spill on deep water. These niay be of the commercial variety or may be made from poles, logs, or other types of floating devices. The placement of the boom on a flowing stream or river is critical. The boom should be placed at an angel to the shoreline to channel the product to shore. The greater the velocity of the flow the greater the angle should be on the boom. Under no circumstances should the boom be placed in a loop configuration. This will channel the product to the center of the loop and under the boom. Skimmer pits should be dug at the downstream end of the boom to retrieve the product out of the channel. 3.4.4 Recovery of Product Layers Greater than 0.5 -inches in Depth on Water Product is more easily recovered when it is present in thicker, larger quantities. Portable skimmers can be used within the boom area to remove the product from the water surface. Vacuum trucks are also a valuable tool when used at skimming pits or when product is present on water. In using any type of powered collection equipment, caution should be used not to ignite the potential vapors. Gasoline powered equipment is not recommended. Air driven pumps are to be used whenever possible. 3.4.5 Recovery of Product Layers Less than 0.5 -inches in Depth on Water As the product gets thinner on the water, it becomes more difficult to pick up. It can be moved by slowly moving the spill boom in toward the shore or by tightening the circle when the spill is surrounded. The product also can be moved by agitating with a fire hose. The use of sorbing agents such as Fiber Perl, Petro Green and. Spag Sorb should be used to pick up the residue. This material is spread thin upgradient of the product and allowed to float into it. As the product is further trapped, more of the sorbent can be spread on top of the product. The sorbent should be allowed to maintain a stationary position for in order to absorb as much oil as practical. Then the sorbent can be raked into a skimmer pit and removed. These sorbents do not absorb water and do not readily release the product. Spent sorbent material should be properly contained and disposed of at an approved facility. 3-3 • Final shoreline cleanup may involve applying emulsifying agents or implementing bioremediation techniques. Approval from the applicable regulatory agencies is required prior to conducting these activities. 3.4.6 Recovery of Spills on Land Product trapped in containment devices should be collected by a vacuum truck and disposed of at the closest terminal or approved disposal facility. Residual thin Layers of product can be cleaned up using sorbents, emulsifying agents, or bioremediation techniques. Prior to applying emulsifying agents or implementing bioremediation techniques, the approval of the applicable regulatory agencies is required. 3.5 Response Materials Response personnel will be properly trained on the use and location of response equipment. Response equipment will be located and secured adjacent to the Town of Parachute Municipal water supply intake. The intake response equipment will consist of a 95 -Gallon Poly -Overpack Spill Response Kit. The kit will contain the following: • 15-3"x4' Booms • 4 — 3" x 10' Booms • 3 — 3" x 20' Booms • 1 — 6'" x 25' River Containment boom • 50— 18"x 18"Pads • 10 — 17" x 17" Pillows • 6 — Temporary Disposal Bags • 6 — Hazard Warning Labels Inspection of on-site response equipment will be conducted annually with items replaced or added as warranted. Predetermined response locations along Parachute Creek will be identified and incorporated within this procedure. Anchor points and equipment will be established at the predetermined response locations to facilitate response activities. 3-4 • • APPENDIX A SPILL CONTINGENCY PLAN DECISION TREE PARACHUTE WATERSHED DISTRICT SPILL CONTINGENCY PLAN DECISION \(1 NO 111"5 1roiiI.IDIA 11.LY I 111.1{A'l l( I\5 51ANA[11:riS 2.
