(EnCana) is submitting this application for the above listed sources at the proposed Middle Fork Compressor Station. This proposed facility will be located in Section 30 of T5S, R96W. This facility is currently in the design phase. As such, the final configuration of the facility may change. New APEN's will be submitted for any changes that are made to the facility. Currently EnCana is investigating the use of utility power at this facility. Depending on the timing of utility power being available to the station it is possible that some portable compressors may be relocated to this facility. In addition there is a Caterpillar 3616 TALE compressor engine package proposed for the Middle Fork Compressor Station. At this time the Caterpillar 3616 TALE compressor engine is not likely to be installed within the next twelve months, although the emissions have been included in the facility emissions summary. EnCana may find it necessary to install additional compression for short-term design needs. Should any portable compressor engine packages be relocated to this facility EnCana will investigate the emissions in terms of RICE MACT applicability and other regulatory requirements. Please include the engine replacement alternative operating scenario (AOS) into the engine permits during processing. gape-kfmw of ErZaPa Corr' n, used (wits Grtr,xe. • As this facility is still in the design phase the configuration of dehydration units may vary. EnCana is requesting the capability of installing any number of different size units to achieve up to 120 MMSCFD of throughput. The enclosed emissions summary includes the worst-case emissions based on two 50 MMSCFD units and one 20 MMSCFD unit controlled with a VRiJ. However any configuration of units may actually be installed. EnCana is also requesting the ability to install either a combustorlcondenser control system or a vapor recovery unit as control for the dehydration units to control the emissions to 95% for both VOC's and HAP's. Again the emissions included in the application are based 011 the worst-case scenario therefore any other configuration will have lower emissions_ Other emiissions sources at the facility included in the emissions summary are emissions that result from pigging and storage tank emissions. The emissions from these two sources at this time are less then 2 TPY and therefore should be APEN exempt emission sources. Please find enclosed all subsequent application and APEN forms. A check to cover the filing fee for the APEN submittal of $599.80 is also included with this documentation. A start-up notice has also been included but will be resubmitted under a different cover letter.

(EnCana) is submitting this application for the above listed sources at the proposed Middle Fork Compressor Station. This proposed facility will be located in Section 30 of T5S, R96W. This facility is currently in the design phase. As such, the final configuration of the facility may change. New APEN's will be submitted for any changes that are made to the facility. Currently EnCana is investigating the use of utility power at this facility. Depending on the timing of utility power being available to the station it is possible that some portable compressors may be relocated to this facility. In addition there is a Caterpillar 3616 TALE compressor engine package proposed for the Middle Fork Compressor Station. At this time the Caterpillar 3616 TALE compressor engine is not likely to be installed within the next twelve months, although the emissions have been included in the facility emissions summary. EnCana may find it necessary to install additional compression for short term design needs. Should any portable compressor engine packages be relocated to this facility EnCana will investigate the emissions in terms of RICE MACT applicability and other regulatory requirements. Please include the engine replacement alternative operating scenario (AOS) into the engine permits during processing. Other emissions sources at the facility included in the emissions summary are emissions that result from pigging and storage tank emissions. The emissions from these two sources at this time are less then 2 TPY and therefore should be APEN exempt emission sources. +**1,-i 14117.2 Please find enclosed all subsequent application and APEN forms. A check to cover the filing fee for the APEN submittal of $599.80 is also included with this documentation. A start-up notice has also been included but will be resubmitted under a different cover letter. If you should have any questions please contact me at (720) 956.3752 or you may reach Denise Kohtala at (303) 904-2 5. Sincerely, Ap) Ri hard S.

In most cases, a permit is applied for and approved before the anticipated commencement date, so the 30 day prior notice causes no problems. Nate: this form isnot a Relocation Notice for portable sources. If, however you plan to commence your operation or activity as soon as you receive the permit, you should estimate the date you expect to commence (assuming the permit is approved) and fill out and return this form at least thirty days prior to that date. This will avoid a 30 -day delay between receipt of the permit and commencement. Notification can be accomplished by completing the form below and returning it to: Colorado Department of Public Health & Environment A PGD -SS -B 1 4300 Cherry Creek Drive South Denver, CO 80246-1530 Please contact the Division immediately (303) 692-3150 if you have any questions or problems concerning this requirement.

(EnCana) to provide dehydration and compression for produced natural gas. Gathering systems in the area transport natural gas from wells to the proposed Middle fork Compressor Station. Once compressed, the natural gas is delivered to a higher pressure system and transported to a location where it is conditioned for sales. Producing wells require that a gathering system operate at low enough pressures that optimize well performance and deliverability. Without the boost in pressure from a compressor station, most wells would not be able to produce into a high pressure system. The wells would not flow and be rendered useless. Once raw natural gas is delivered to the inlet of a compressor station, free liquids (hydrocarbon and water) are separated using conventional separation equipment. This separation is critical to prevent damage to compression equipment. The hydrocarbon liquids are measured and combined with other liquids and sold. The water is then hauled to an approved water treatment and disposal facility. Once the gas is compressed, it is then dehydrated using a triethylene glycol (TEG) dehydration system. As the gas is contacted with lean TEG, the water is absorbed by the glycol, thus removing it from the gas. The glycol and water (rich) solution is sent to a reboiler where the water is driven off as steam. The lean TEG is then sent back to a contactor for a continuous removal of water from the gas stream. Once dehydrated the gas is then delivered to a common high pressure line and sent to a facility for more conditioning. Once conditioned, the gas is then sold and delivered to markets in the area. EnCana will maintain compliance with the conditions of the County and State authorizations and the operator must be familiar with the conditions placed on operation of the facility. Also, industry standards regarding equipment, construction, and operation will be upheld. The operation and condition will be checked at least once per day. The daily check will be conducted by site personnel who spend the majority of their work shift in the immediate area of operations. At most, routine operation of the facility will require two round trips per day of a pickup or similar vehicle from Parachute, Colorado to the site. • • Impact Statement Site location selection for the Middlefork Compressor Facility provides multiple benefits. The proposed location is within a previously disturbed area which was used for oil shale processing on the former Unocal Property. The proposed facility will be in a central location to current and future natural gas wells in the area. The facility will set on approximately 4 acres of a 27,000 acre property solely owned by Encino Oil & Gas (USA) Inc. The site is in a relatively remote area with the nearest residence being approximately 3 miles to the south. The steep terrain surrounding the site on three sides serves as a natural buffer for and potential noise, odor and dust concerns. Due to the remote location of the property, visual impacts from the facility will be extremely limited. The facility will be in continuous use and operation 24 -hours per day, year-round. however, the majority of activity will occur during normal business hours. Remote monitoring of the facility after completion of the construction phase will limit the need for on-site personnel only during the daylight hours. The anticipated traffic impact to Garfield County Road 215 will be approximately 4 pickup trips per day under normal conditions of operation. EnCana's Gas Control Department will have monitoring and control ability from their office facility located just north of Parachute, Co. Gas powered compressors are planned for the initial phase of the facility operations. These compressors will not exceed the noise or vibration limits set forth by the State of Colorado Revised Statute 25-12-103. Given the remote location of the new facility, noise will not be a nuisance to area residents. EnCana plans to convert the new compressors to electric powered motors as produced natural gas volumes increase and as economics warrant. Negotiations are currently ongoing with Excel Energy to provide three phase power service to the proposed facility site. The facility site has been designed to insure protection of ground water and nearby streams through the development and implementation of a Storm Water Management Plan, specific to the area. Containment facilities are designed into the facility for any hazardous material stored or used during operations. There will be no sewage or solid waste generated on the site. A security gate located at the entrance into the subject property precludes public access to the site. The security gate is manned 24 -hours/ 7 days a week in order to limit unauthorized traffic onto the property. According to wildlife distribution maps from the Colorado Division of Wildlife, the site is located on winter rangeland for mule deer, elk, and turkey. This facility is by nature incompatible with continued wildlife access; therefore, wildlife will be excluded by fencing the property. EnCana has retained the services of a certified wildlife biologist to insure the safety and protection of wildlife potentially affected by the operations of the facility. All equipment will be painted with a beige color to match the color of the surrounding area. The expected life of the facility is approximately 20+ years. A comprehensive reclamation plan will be in place to insure return of the site to a natural state once the facility is no longer needed. • • Davis.

Soil/Weathered Rock Excavation: Soil or weathered rock that can be reasonably excavated with the rock auger, i.e. rock auger advancement is greater than 6 inches per 15 minutes. B. Sloping Weathered Rock Excavation: Excavation of soil/weathered rock that can typically be excavated with the rock auger, except the steeply sloping orientation of the stratum causes the rock auger to run askew. C. Rock Excavation: t . Excavation of material that meets the rock auger refusal criteria and requires the rock core barrel or other hard rock excavation techniques for removal. 2. Rock auger refusal is defined as a penetration rate of less than 6 inches in 15 minutes, while operating a caisson drilling rig, rated with a torque capacity of at least one million inch -pounds, applying a continuous down pressure of at least 50,000 pounds, equipped with a rock auger that contains conical carbide -tipped ("Kennemetal") teeth. D. Nominal Soil or Weathered Rock Seams Nominal soil or weathered rock seams below rock auger refusal will be excavated and considered as rock for rock excavation quantities. A nominal soil or weathered rock seam is one which is less than 2 feet thick. Where soil or weathered rock seams or voids of 2 feet or greater are excavated within a mixed rock/soil or rock/weathered rock profile, excavation is classified as soil/weathered rock excavation until rock auger refusal is again established. 1.8 MEASUREMENT AND PAYMENT FOR ROCK EXCAVATION A. Measurement: Excavation type in units of length shall be considered to change at the upper contact with a different excavation type as defined by Section 1.7. B. Payment: Contract unit rates per length of each diameter caisson shall be provided for each excavation condition type noted above in Section 1.7. Contract price and time will be adjusted for overruns or underruns. C Payment for Differing Site Conditions: No payment will be made for any rock excavation beyond caisson limits.

No sack rubbing or sandblasting will be required on formed surfaces. 3. No grinding will be required on formed surfaces, other than that necessary for repair of surface imperfections. 4. The repair of defective concrete and filling of holes left by the removal of fasteners from the ends of tie rods and the specified curing shall be required for all classes of finish. C. Classes of Formed Surface Finishes 1. Finish F1 applies to formed surfaces upon or against which fill material or concrete is to be placed. The surfaces require no treatment after form removal except for repair of defective concrete and filling of holes left by the removal of fasteners from the ends of tie rods and the specified curing. Correction of surface irregularities shall be required for depressions only and only for those which exceed 1 inch. 2. Finish F2 applies to all formed surfaces not permanently concealed by fill material or concrete, or not designated in the interior finish schedule, on the drawings, or in these specifications to receive Finishes F1, F3 or F4, or Special Finish BFT. Surface irregularities shall not exceed 1/4 inch for abrupt irregularities and 1/2 inch for gradual irregularities. 3. Finish F3 applies to formed surfaces, the appearance of which is considered by the Engineer to be of special importance, such as surfaces of structures prominently exposed to public inspection. Surface irregularities shall not exceed 1/4 inch for gradual irregularities and 1/8 inch for abrupt irregularities, except that abrupt irregularities will not be permitted at construction joints. 4. Finish F4 applies to formed surfaces for which accurate alignment and evenness of surface are of paramount importance from the standpoint of setting equipment and maintenance of specified clearances. Abrupt irregularities shall not exceed 1/4 inch for irregularities parallel to the direction of flow, and 1/8 inch for irregularities not parallel to the direction of the flow. Gradual irregularities shall not exceed 1/4 inch. 5. Special Finish BFT applies to the formed surfaces designated on the architectural drawings or in the interior finish schedule to receive a board form texture finish. Except for the formed grooves, cone holes and the V- shaped fins, surface irregularities shall not exceed 1/4 inch for gradual irregularities and 1/8 inch for abrupt irregularities. Abrupt irregularities will not be permitted at construction joints. D. Upper Surface Finishes 1. Screeded finish is for surfaces of roads or of foundation beds, slabs and structural members to be covered by backfill, subsequent stages of construction, bonded concrete topping or cement mortar beds to receive pavings, and on exposed surfaces of paving where a superior finish is not required. The finished operations shall consist of levelling and screeding the concrete to produce a uniform, plain or ridged surface, with surplus S:IPrajecls14107-0itSPECIFICATIRNS103300 Cast to Place Cancra;e.doc REVISION i} Samuel Engineering, Inc.

Wood floated finish for surfaces of beds and slabs to receive mastic pavings or block or the pavings bedded in mastic and for exposed surfaces or pavings where a hard smooth steel trowelled surface is not required. Floating shall be carried out after the concrete has hardened sufficiently and may be by hand or machine. Care shall be taken that the concrete is worked no more than necessary to produce a uniform surface free from screed marks. Steel trowel finish is a hard smooth steel trowelled finish for surfaces of concrete pavings, tops of walls, coping and other members exposed to weathering, surfaces of beds and slabs to receive thin flexible sheet, and tile paving bedded in adhesive, and seatings for bearing plates and the like where the metal is in direct contact with the concrete. Trowelling shall not commence until the moisture film has disappeared and the concrete has hardened sufficiently to prevent excess laitance from being worked to the surface. The surfaces shall be troweled under firm pressure and left free from trowel marks. 4. Broomed finish is a brushed finish for surfaces of pavings and slabs where specified. It shall be finished as specified for smooth steel trowelled finish, except that the hard steel trowelling shall be omitted. After the machine trowelling is completed, the surface shall be brushed with a fibre bristle brush or broom across the direction of traffic. E. Surface Hardeners 1. Hardeners, when required, shall be as specified on the drawings and applied to surfaces where indicated in the drawings, in accordance with the manufacturer's instructions. 3.8 CURING AND PROTECTION A.

In the event of a fire • In the event of a fire, all personnel and appropriate equipment on site will be committed to fire containment and control. • The BLM and appropriate fire authorities will be notified immediately. • Direction of fire control efforts will be transferred to appropriate fire fighting agency personnel upon their arrival on site Part VI Soil Features The United States Department of Agriculture Soil Conservation Service Soil Survey of Rifle Area, Colorado provides the following information about the soils and environment in the area of the facility: 46-Niihill channery loam, 1 to 6 percent slopes. This deep, well drained, nearly level to gently slopeing soil is on alluvial fans and side of valleys. Elevation ranges from 5,000 to 6,500 feet. The soil formed in alluvium derived from Green River shale and sandstone. The average annual precipitation is about 13 inches, the average annual air temperature is about 48 degrees Fahrenheit, and the average frost -free period is about 125 days. Typically, the surface layer is light gray and very pale brown channery loam about 11 inches thick. The upper part of the underlying material is very pale brown very channery loam about 14 inches thick, and the lower part is very pale brown extremely channery sandy loam and extremely channery loam to a depth of 60 inches. Included with this soil in mapping are small areas of Arvada and Ildefonso soils, The Arvada soils are nearly level and Ildefonso soils are steeper. These areas make up 10 to 15 percent of the soil map unit. Permeability is moderately rapid, and available water capacity is low. Effective rooting depth is 60 inches. Surface runoff is slow and the erosion hazard is moderate. This soil is used mainly for grazing and wildlife habitat. Some small areas are in irrigated hay and pasture. The native vegetation on this soil is mainly wheatgrass, needleandthread, and sagebrush. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, undesirable weeds and annual plants are numerous. Properly managing grazing maintains and improves range condition. Reducing brush improves the range. Seeding improves range in poor condition. Crested wheatgrass, western wheatgrass, and Russian wildrye are suitable for seeding, Preparing a seedbed and drilling the seed are good practices. Mule deer, cottontail rabbit, chukar, and squirrel find habitat on this soil. This soil has few limitations for community development. Community sewage facilities will be needed if population density increases. This soil is in capability subclasses IVe, irrigated, and Vie, nonirrigated. • ENVIRONMENTAL SCIENCE CORP.

The quality control samples include a method ank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of reagent water carried through the entire analytic process, The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and [Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier. Page 6 of 6 • ENVIRONMENTAL S CIENCE CORP Cordilleran Compliance Services, Inc.

The proposed natural gas compression facility is to be owned and operated by Encana Oil & Gas Inc. Location The proposed facility is located in the southwest of Section 30, Township 5 south, Range 95 west (Figure 1). The nearest town is Parachute, Colorado. From Parachute the site is eleven miles to the north on Garfield County Road 215. County Road 215 lays to the east of Parachute Creek. The site hes to the north of East Fork of Parachute Creek which flows into Parachute Creek nearby. The site was previously occupied by a Unocal Oil Company facility. Remnants of foundations, storm sewers, utilities, and process facility equipment are presently on the site. Topography The site sets at 5800 feet above sea level. Mesas rise all around this area. The nearest mesa is adjacent to this location to the north. Its elevation is nearly 8100 feet above sea level. The slope of this mesa, running into the site, is steep. Slopes ranging from vertical walls to thirty -degree slopes are found. At the bottom of this slope the grade is more moderate, Here, at the toe of this slope, the site has been leveled. The slope of site itself runs gently to the south and more steeply to the west, Drainage The principal drainage is the East Fork of Parachute Creek. The hydraulic length of its drainage basin is more than 13 miles. At the site it flows principally east to west. The height of the 100 -year flood is unknown but should be investigated for construction purposes. Storm flow at the site will come frorn the east from the East Fork of Parachute Creek and, to a lesser extent, off the slope of the mesa to the north. Both of these drainages should be considered when designing the site. Drainage on site presently flows gently to the south and more steeply to the west. t Vegetation The creek area is heavily covered in trees, bushes, and grasses. The slope of the mesa is sparsely vegetated and is susceptible to erosion. This study found evidence that in the past large quantities of the adjacent slope's sediments have 2 washed into the local area. Sediment control should be considered when designing site drainage. The site itself is overgrown in grass, bushes, and a few small trees. There are however a few large cottonwood trees that will probably be removed for site construction. The surveyors of this site were locating large trees as well as other useful information. Geotechnical Exploration Six boreholes were drilled on site with a CME 75 on October 28, 2004 (Figure 2). A six-inch hollow stem auger was used. The weather was cold. It rained in the morning and early afternoon. The rain turned into snow by late afternoon. Some soil samples may have slightly less actual moisture contents than was tested due to the inclirnate conditions. Borehole numbers one through five were drilled to twenty feet below grade while borehole #6 was drilled to thirty feet below grade. The logs for these boreholes are found in the Appendix. The elevations of the boreholes were measured by the surveyors as follows: Borehole #1 Borehole #2 Borehole #3 Borehole #4 Borehole #5 Borehole #6 5861' SL 5809' SL 5814' SL 5809' SL (5805') 5808' SL 5814' SL Borehole #4's elevation was changed due to the drilling rig's inability to negotiate that area's muddy conditions. The bore was moved slightly to the west off of the edge of the existing foundation's pad. The change in elevation was estimated as four feet. Surface Geology The site is covered in recent sediments carried down the slope of the mesa to the north and fluvial deposits from the East Fork of Parachute Creek. In general the gravel size is larger at the surface and in greater quantity at depth. The gravel's angularity spans from angular to subrounded. It tended to be more rounded at depth. The gravels at the surface here are mosttly subangular. The gravels were composed of siltstone, mudstone and shale Shale was predominate at the surface. The shale samples tested showed to be weathered claystone. The sand fraction was also composed of siltstone, mudstone, and shale. The sand fraction appeared to increase with depth. The sand fraction had softer angularity when compared to the gravels. The fine fraction was silty and • • • clayey. In general it appeared to be more clayey with layers of clay interbedded between the coarser sediment. The standard penetration tests (SPT) were ran mostly at 2 5', 5', 10', 15' and 20' below grade. Some intermediate SPTs were also ran. Samples were taken at most boreholes at these depths. The SPT's blow count indicated that with few exceptions the sediment beneath the site was loose, where the blow count corrected to 60% efficiency ranged from 4 to 10, The blow count refers to the number of times it takes a 140 pound hammer falling 30" to drive a 2.5" Q.D. sampler 12". Medium dense (corrected blow count) ranging from 10 to 30 occurred near the surface of the boreholes and the dense material occurred at the bottom of two holes (#4 and #6) at 5785' SL. Very loose layers existed as follows: Borehole #1 Borehole #2 Borehole #6 *bgl = below ground level 10' bgl* 81 bgl 16' bgl 5' bgl 10' bgl 25' bgl 5796' SL 5802' SL 5794' SL 5809' SL 5804' SL 5789' SL The site sampling and testing appear to indicate that site soils were quickly deposited. Both flood and mudslides can be quickly deposited. The denser material appearing at depth may be a remnant of the main channel or positioned nearby the channel. Therefore one may hypothesize that early on the East Fork of Parachute Creek was nearer or under the site, mudslides would occur and wash off the slope of the mesa blocking the creek and pushing it further to the south. Occasional flooding would erode portions of the mudslide and deposit the sands and gravels carried by the creek. As the creek moved away from the site, more and more fines were deposited. This phase characterized further bank depositions. These processes continued until the sediment is found as it is today. Discussion of Soil Properties A. General Site Characteristics 1. Soil Classifications: The site design soil is found at the surface nearly three feet below grade. Deep soils were considered and tested but not classified since the use of a deep foundation would not be based on classification. The 4 surface soil properties were tested using ASTM D-2487, as follows: 25% Gravel 62% Sand 13%© Fines mostly clay Of that sand portion a significant day fraction exists. The Atterberg limits (ASTM D-4318) were tested on both the sediments retained in the number 20 sieve and number 200 sieve. It was found that the number 20 sieve composed 15% of the sand fraction and that this fraction was weathered claystone. The limits for it are as follows: Plastic. Limit = 16% Liquid Limit = 27% Plastic index = 11% The claystone quickly soften upon introduction of water and was moldable with work. The number 200 sieve fraction was also tested with the following results: Plastic Limit = 20% Liquid Limit = 35% Plastic index = 15% The number 200 sieve sediment also was moldable upon introduction of water. The 200 sieve held 23%a of the sediment. Based on these tests the fine fraction of the sample should be increased by 23% + 11% which is 34%. Given 12% in the pan there is a total adjusted fine fraction of 46%. Since nearly 50% is retained on the number 200 sieve and the plastic limit is 15 then the soil has an ASTM designation of SC, a clayey sand with gravel or CL a sandy lean day with gravel. Again the gravel and sand portion are fragments of shale, siltstone, and mudstone_ These are fairly soft rocks and should not be compared to the sands and gravels found in the nearby Colorado River which tCome predominately from metamorphic rocks which are at least eight times more indurated than these soft sedimentary rocks. 2. Geologic Hazards: Sediment flows from the slope to the north of the site, unconsolidated subsurface sediments and possible sediment deposits by flash floods from the East 5 Fork of Parachute Creek. These items should be addressed in the design and construction of the facility 3. Potentially Unstable Slopes: The slope to the west rises more than 2300. The individual slopes Form according to theft composition. More indurated siltstones tend to form vertical slopes whereas the softer more weathering susceptible shales or claystones tend to form more moderate slopes ranging from 30° to 60°. This slope, to the north, may fail when the soil is saturated. The shales are particularly susceptible to carrying mudflows down steep ravines during heavy rainstorms. 4. Swell Potential: The soil's plastic index (PI) at 3' below grade on borehole #2 was 15. This sample was typical of surface soil. A Pt of 15 represents a soil with low to medium swell potential. All samples tested showed no swell under load when introduced to water. 5. Consolidation Potential: The SPT tests ASTM D-1586 indicates the subsurface soils are loose. The exception is found near the surface where mechanical compaction has taken place and at deeper depths where the more gravelly soils exist. The results of one dimensional consolidation tests (ASTM 2435) also show that the soil samples can be considered unconsolidated. The results of these tests are as follows: Borehole # Depth (ft) Load (psf)* Settlement (%) 4 20'/2' 5500 10 2 2 W 1500 5 1 11 Y2' 2000 8 6 15' 4000 7 3 2 W 2000 22 1 3' 2000 8 *psf = pounds per square foot pcf = pounds per cubic foot The settlement noted in borehole #3 is much more than what is expected according to that sample blow count of 51. Therefore the sample may have become unconsolidated during the SPT test or when handling the sample. It is expected that the settlement of the surface soil will range from 5% to 10% under a 2000 psf load. This amount of settlement is typically unacceptable. 6 • 6. Water Table: The soil was dry at surface and became more moist with depth. A free water table was found in borehole #6 and borehole #3. These are the two eastern most boreholes. The water table was found at 20' below grade (5794' SL) on borehole #6 and at 17' below grade or 5797' SL on borehole #3. The water table was not encountered on the other four boreholes. It maybe that a paleochannel is positioned nearby borehole #3 and #6 and these two boreholes are hydraulically isolated from the other boreholes. It also maybe that the other boreholes have less permeable soil. The boreholes were not checked one day later to gauge the water table. The water table may be assumed to exist at nearly 5794' SL. 7 Corrosivity: All concrete and buried material should be designed to resist corrosion due to local alkaline soil. Concrete is especially susceptible to sulfate corrosion. 8. Rock Outcrops: Rock outcrops are found on the surrounding mesas. No bedrock was found on site to a depth of 30'. Area outcrops are typically shale, siltstone, and mudstone. Grading and Excavation Considerations 1. Potential Construction Difficulties: The site slopes down to the west. There is a possibility that fill will be required. Suitable fill material may not be found on site. In the event large quantities of fill are required, the surrounding area should be investigated for a potential source. The current source of "structural fill' is large chunky shale. This could be used for fill at depth when thoroughly mixed with finer material. This fiIlris currently being excavated on site. The extent of this fill is unknown. Structural fill for the site will have to be transported to site from a gravel pit operating on the Colorado River Valley. The eastern side of the site is currently used as storage space for pipe and equipment. The western side of the site is occupied by the remnants of Unocal's old facility. On the western side, large concrete pads, tprocess equipment, foundation pads and utilities exist. Some items will be removed but some may be used on site. The concrete pads may be hammered on site and removed for use in erosion control. They also may be buried in the subsurface away from any foundation. Likewise the existing foundation pads, constructed of shale chunks, may be mixed in with the 7 surface soils. The geotechnical engineer should be consulted on issues regarding on site fill properties and the compaction required. A low water table exists on site. The surface moisture content is low. Therefore no caving is anticipated during expected shallow excavations. Suitability of Native Material for Trench Backfill and Structural Fill: The native material at the surface is classified as a sandy lean clay with gravel or a clayey sand with gravel. This type soil is unsuitable for structural fill. The native material is suitable for bedding and backfill for the appropriate situations. These situations would include gas lines, water fines, and some sewer lines. 3. Compaction of Subgrades and Fills: Ali soil is to be compacted to 95% of the standard proctor — ASTM D-698. The standard proctor for the site's surface soil tested to be 113 pcf at 12% moisture content. The average dry density of good structural fill is approximately 136 pcf. C. Retained Earth Pressures 1. Lateral Earth Pressures: The soil is a clayey type with high lateral active pressures. The design lateral load for this soil is 60 psf per foot of depth. Design lateral loads consider a flat grade on the retained earth. The design lateral load is based on moist conditions for the specified soils at their optimum density. The lateral active pressure does not consider sloping backfill, surcharges or saturated soil conditions. For relatively rigid walls, as when braced by floors, the design lateral loads should be increased to 100 psf per foot of depth. The retaining structure should not consider passive pressures unless design conditions require use. In that case the type soil's passive pressure is 210 psf per foot of depth, This value assumes a moist soil at optimum density. Coefficient of Friction to Lateral Friction for Movement: The coefficient of the design soil ranges from 0.3 to 1.0 considering wet to moist conditions. 3. Cohesion: The cohesion of the surface soil calculates to be 480 psf. • • • Backfill Compaction: The trench and wall backfill compaction should be 90% of ASTM D-698. The compaction should be increased for traffic areas. The amount and extent of such compaction should be considered on a case by case basis. D. Foundations 1. Frost Depth: The base of all foundations shall be as deep or deeper than 36" below grade. 2. Allowable Bearing Pressures: Four different methods of determining allowable bearing pressure for the surface soil were studied. The first method depends on soil classification. The type soil is classified as "SC" or "CL". The presumptive allowable bearing pressure, according to the Uniform Building Code (UBC) is as follows: Type Soil Allowable Bearing Pressure SC 1500 psf CL 1000 psf The Garfield County Building Department uses the UBC. The allowable bearing pressure was also calculated using SPT data. This data indicated there is a weak and very loose zone at nearly 5' below grade on borehole #6. The extent of this zone is unknown but should be considered pervasive. The bearing pressure calculated here was 1140 psf for a continuous footing and 660 psf for a mat footing. This same soil calculated to have a bearing pressure of 1320 psf using Terzaghi's method for a continuous footing. A less conservative method was considered using settlement analysis. A sample from borehole #2 at 2 1/2' below grade was tested using ASTM 0-2435. That sample had a total settlement of 6.4% at a 2500 psf load. It was found that when considering a continuous footing, buried at three foot below grade and over 1' of structural fill, the allowable bearing pressure is 1660 psft Given that another sample at 2 %' below grade settled 22% at 1500 psf and 7.2% at 1500 psf for yet another sample at 3' below ground level the allowable bearing pressure is less than 1660 using settlement analysis. 9 Given the loose conditions of the subsurface and the significant clay fraction it is recommended that an allowable bearing pressure of 1100 psf is used to design continuous footings, isolated pads, column pads and 660 psf is used to design mat foundations. These values could be increased with further testing using trenches and a shear vane test (ASTM D-2573). The allowable bearing pressure for structural fill is 2500 psf. Structural fill should be considered to carry the Load to the soil at a 38° angle extending outward and downward from the edge of the footing. That extended area, under the footing, shall be considered as the total bearing area onto native soil. Deep foundation soil carrying capacities were also considered. It was found in general the soil was looser than necessary for deep foundations at most of the depths in the boreholes. However, at 5785' SL there appears to be a competent soil. In the event piers are considered a friction (downward and upward) of 750 psf shall be used and an end allowable bearing pressure of 8200 psf. Both values are calculated using site tests. The less dense nature of the soil and decreased clay contact on the wall of the pier contribute to low design values. The end bearing pressure should be neglected in the event of hole caving. Test piers should be constructed and loaded prior to overall use. Settlement could be in excess of requirements. 3. Soil Weights: The soil's bulk densities were measured and calculated as follows: Borehole # Depth (feet) Bulk Density (pcf) Moisture % 1 3' 108 9' 3 2/2' 90 10' 2 2W 106 10' 4 20 W 96 10' 1 11 '/z' 110 23' 6 15' 125 18' The bulk density of borehole #3 represents a collapsible condition. Typically soil weights less than 90 pcf show moderate to severe settlement upon wetting and load. The other surface densities probably represent areas where the surface soils have been compacted of roadbase by truck traffic and heavy equipment, This should also be the case I0 • for borehole #3 however the recent compaction apparently did not affect the density at that depth • • The surface density of the recently compacted roadbase was also tested. It was measured at both borehole #6 and borehole #3. That data is as follows: BH # Density(pcf) Optimum Density(pcf) % Compaction 3 126 136 93 6 124 136 92 This compacted roadbase is less than the 95% compaction specified herein. 4. Types of Foundations Costs should be compared between necessary dirt work for surface foundations and drilling piers to more than 30' below grade. The depth of piers would depend on site conditions. The surface foundations will be underlain with compacted structural fill over 1 1/2' foot of compacted earth. Surface foundations include isolated pads, spread footings, column pads and mat foundations. Isolated pads, spread footings and column pads shall be designed using an 1100 psf allowable bearing pressure. The mat foundation shall be designed using 660 psf allowable bearing pressure. These mats should be isolated from other concrete structures to allow free movement. All footings shall be reinforced per design requirements. Stemwalls should be designer) to span 13'. Rebar shall be placed at the top and bottom of the stemwall. Compacted earth and structural fill is required under slabs, footings and unsupported sternwails (grade beams). Deep foundations in the area are typically drilled in place concrete piers. Here the entire footprint of the foundation is excavated and then drilled on a pattern specified by the structural engineer. The piers shall be designed as follows: Minimum Depth: 30` Minimum Diameter of Piers: 10 inches Minimum Penetration into Bedrock: N/A Minimum Deadload: N/A • • Maximum End Bearing: NIA Downward Friction Pressure: 750 psf Upward Friction Pressure: 750 psf The piers shall not be placed closer than 6' apart. The first 5' of the pier shall be neglected when calculating skin friction. The pier setting depth shall be determined by the geotechnical engineer. It is probable that the depth will be approximately 30'. The holes shall be cleaned thoroughly and covered upon drilling to total depth. Concrete, specified by the structural engineer, should be pumped from the bottom of the hole via a hard line stinger or suitable alternate method. The pump flow rate should be sufficient to dean debris from the bottom of the hole and scour the walls. The tops of piers shall not be mushroomed. Mushrooming may be eliminated by installation of short sana tubes set to grade. The concrete shall be set in the piers immediately after drilling. A low shrink corrosion resistant concrete is recommended to prevent gaps between the pier and the hole. This allows for maximum attainable pier friction. The grade beam should rest directly over the pier and be attached to same by means of a corrosion resistant steel rod. This will allow the grade beam to move upward (or the pier downward). With this system the structure may be easily leveled and repaired in the case of extreme movement. Other deep foundations that may be used are helical piers and piles. 5. Floor Systems: We believe the compacted near -surface soils and compacted site grading fill can exhibit low movement potential. Some movement must be assumed from an increase in moisture. A slab -on -grade floor can be used in buildings provided the owner is aware of and accepts risk of potential movement. Driveways, sidewalks and exterior slabs are also constructed as slabs -on -grade. We recommend the following precautions for construction of slabs -on -grade at this site. These precautions will not prevent movement in the event the underlying soils become wetted but they tend to reduce damage if movement occurs. 1. If a structural fill is required to achieve grade then resulting subgrade should be scarified, moisture 12 • conditioned to within 2 percent of optimum moisture content and the top 6" compacted to at least 95 percent of maximum standard Proctor dry density (ASTIV1 D-698). One foot of compacted native soil should be placed over this compacted soil, structural fill then can be used to meet grade. Structural fill soils should consist of a maximum particle sized of 6 -inches, a maximum of 30 percent passing No. 200 sieve and a maximum liquid limit of 30. Structural fill should be moisture conditioned and compacted in maximum 10 --inch loose lifts as stated above. 2. Slab -on -grade construction should be limited to areas such as building interiors and exterior flatwork. 3. Slab subgrade areas should be scarified, moisture conditioned and compacted as described in this report. 4. Slabs should be separated from exterior walls and interior bearing members with a slip joint which allows for free vertical movement of slabs. 5. The use of slab -bearing partitions should be minimized. 6. Underslab plumbing should be eliminated where feasible. Where such plumbing is unavoidable, it should be thoroughly pressure tested during construction for leaks and should be provided with flexible couplings. Gas and water lines leading to slab -supported appliances should be constructed with flexibility. 7. Plumbing and utilities which pass through slabs should be isolated from the slabs. Heating and air conditioning systems supported by the slabs should be provided with flexible connections capable of at least 1.5 inches of vertical movement so that slab movement is not transmitted to the duct work. 8. Frequent control joints should be provided to reduce problems associated with shrinkage and curling. The American Concrete Institute (ACI) and Portland Cement Association (PCA) recommend a maximum panel size of 8 to 15 feet depending upon concrete thickness and slump, and the maximum aggregate size. We advocate additional control joints 3 feet off and parallel to grade beams and foundation walls. 13 9. Exterior slabs should be designed to function as independent units. Movement of slabs -on -grade should not be transmitted directly to the foundations. 6. Perimeter Drains and Groundwater: All runoff water should be diverted from the building site. Gutters should be used around the perimeter of the roof. The use of v -pans and/or French drains is strongly recommended at each gutter termination. V -pans and like items should transport water away from the building for a minimum of 5' prior to release into soil Drainage and Irrigation 1. Permeability: The surface soil permeability ranges from 5 x 1 g-& to 2.5 x 10-7 cm/sec. 2. Hydrologic Soil Group: The site soil is a "C" or "D' type soil, which has low infiltration rates when thoroughly wet. Group "C Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group "D": Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a permanent high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. 3. Irrigation Practices: No planting is recommended within 5' of the perimeter of any building. Excessive watering is not recommended in any case and may lead to differential settling of the foundation or concrete flatwork. The best practice is to install a 5' concrete walk (around the perimeter of the structure, sloped 2% to the outside. This method has proven very effective in keeping water away from the foundation thereby preserving its integrity. 14 4. Grades Around Buildings: It is recommended that the grades around buildings are at least 1O% for 10' extending from the perimeter of any building. 5. Site Preparation: All organic matter should be gathered and eliminated. This would include all trees, shrubs, and grasses. No organic matter should be introduced into the site's soil All topsoil should be removed and stock piled for later use if required. In the event the topsoil is relatively organic free it may be used for fill. Existing concrete flatwork should be removed and buried under roadways on site or used for erosion control, Existing "structural fill" which is composed of large shale chunks should be thoroughly mixed with soil and use for site fill. Once the site is cut to grade, and before any fill is placed, the soil should be compacted in place with a vibratory roller to 95% of ASTM D-698. All native fill and native fill mix should also be compacted to 95% of ASTM D-698. The top 1' of fill should be 1' of roadbase compacted to 95% of the standard proctor. Lesser compaction may be used in storage areas and less traveled roadways. Building sites shall be excavated to 5' below grade and at least 2' to the outside of footings. The tap_ 6' of soil shall be compacted in place in the excavated area, using a vibratory roller. Then 1' of native soil will be placed pnd compacted in place. Then a minimum of one foot of compacted roadbase will reside onto the compacted earth. Excavation for deep foundations require excavations to 3' below grade and compaction of the top 6" of native soil, This assumes that the grade beam connecting the piers will reside below frost depth. Road Design The surface soils have a calculated AASHTO group index of 4.4 (Appendix). This group index corresponds to the following soil properties: 15 • • Soil Support Value - 5.5 R Value (California) - 35 CBR - 7 Modulus of Rupture (MR) - 7500 psi Subgrade Modulus (K value) - 100 psilin Extensive road work should consider using actual CBR values for design, The group index should be used only for preliminary design and limited road work. C values for road design are as follows. Item Coefficient Hot Bituminous Pavement 0.44 Crushed Stone Base 0.14 Compacted Native Soil 0.07 G. Concrete Sulfate concentrations may have a severe effect on concrete which comes into contract with the soils. Type V (sulfate resistant) cement should be used for concrete that comes into contact with the subsoils. Type V cement is not always available locally. Locally available Type I / 11 modified cement has been used for similar conditions. This cement may be substituted for use if Type V is unavailable. H. Borings 1. Six geotechnical bores were drilled on this site as shown on Figure 2. Limitations The content of this report is based on subsurface and surface observations made at the time of the site investigation. The content of this report is also based on laboratory testing and professional literature. Subsurface observations and lab tests results are point -site specific. Subsurface conditions often change in a site both horizontally and vertically. Therefore, depending on the amount of testing and boring performed, the resulting data and interpretation thereof may or may not represent the overall site conditions. No warranty or Yepresentation either expressed or implied is included or intended in this report. Due to changes in engineering practices, this report is valid for two years. 166 We recommend that a qualified professional read this report and discuss any portion necessary with us in order that the proper design of the structure may be implemented. Minimum design criteria are given herein, it is the designer's responsibility to use the appropriate safety factors. We recommend that geotechnical inspections be performed, once dirtwork commences, to assure quality control and that assumptions made herein are valid.

Due to the remote location of this facility, landscaping efforts will be directed at erosion control as opposed to mitigation of visual impacts. Any areas disturbed by construction or operation activities that are not otherwise covered by liner material or equipment will be resurfaced with sand and gravel and graded flat or vegetated, as necessary. Reclamation The expected life of the NPR Water Storage Facility is 20 years. Reclamation will consist of the following: Removal of all surface equipment and liner material. Restoration and re -contouring of grade to approximate original conditions. Replacement of stockpiled topsoil. Compliance with all prevailing Colorado Oil and Gas Conservation Commission and Garfield County regulations governing final reclamation. • • • ENCANA OIL & GAS (USA) Inc. MIDDLEFORK COMPRESSOR STATION STORM WATER MANAGEMENT PLAN MAY 20, 2005 Encana Oil & Gas (USA) Inc. Middlefork Compressor Station Storm Water Management Plan SECTI©N 1 INSTRUCTIONS FOR COMPLETING THE SWPPP The generic Storm Water Management Plan (SWMP) meets the criteria of the Federal requirements as well as the State of Colorado. Unless specifically requested by a regulator, the SWMP does not need to be sent in to any agency. You are required to have this plan stored at the office which is closet to the construction.

SECTION 3 • • • ENCANA OIL & GAS (USA) Inc. MIDDLEFORK COMPRESSOR STATION STORM WATER MANAGEMENT PLAN 1. INTRODUCTION The stormwater permit requires the use of self -designed SWMPs. These plans are based on the use of BMPs. For construction sites, there are several types of BMPs: those that prevent erosion, those which prevent pollutants from the construction materials from mixing with stormwater and those which trap pollutants before they can be discharged. Sediment controls typically include: • minimizing the amount of disturbed soil • preventing runoff from off-site areas from flowing across disturbed areas • slowing down the runoff flowing across the site • removing sediment from on-ste runoff before it leave the site The goal of Stormwater Management Plan (SWMP) is to improve water quality by reducing pollutants in stormwater discharges. 2. PROJECT DESCRIPTION Encana Oil & Gas (USA) plans to construct a compressor station on 18 acres in the North Parachute area on an existing facility location. This includes a 4 acre retention pond that will contain runoff from the facility. The entirety of the surface area is fee land owned by Encana. The Middlefork Compressor Station is located in Garfield County and can be accessed from I-70 by exiting at Parachute and driving NW on Road 215 directly to the site. The approximate center of project area is N 39° 34' 49.025", W 108° 6'.14.407". 3. DISTURBANCE ESTIMATE The total area of the project is 18 acres. The area of this project that will undergo disturbance is 18 acres. The construction period is estimated to be 3-4 months. Encana Oil & Gas (USA) Inc.

This manual provides design criteria for a variety of techniques to address these issues. These techniques, or BMPs, consist of both temporary and permanent solutions to reduce pollution from a construction site. The majority of BMPs address onsite soil losses. For construction sites, soil loss. In the form of erosion and sedimentation as results of storm events and wind, constitutes the majority of pollution generated from a construction site. BMPs which address erosion and sediment control are much more site specific than waste management techniques. Erosion and sediment control BMPs are dependent upon site slopes, drainage patterns and quantities, and other site specific conditions. Waste management consists of "good housekeeping" practices which are dependent upon the type of construction and the quantity and type of building materials. The following provides a method of selecting BMPs applicable to construction sites along with design criteria for each BMP. There may also be state or local manuals which list common BMPs for your region. In preparing the SWPPP, the designer must first use the bmp selection guide to determine BMPs applicable to the site. The fact sheets following the selection guide detail the design and maintenance requirements, limitations, and purpose of each design and the techniques. These provide the tools for the designer to select the appropriate BMPs and locate them onsite to effectively reduce sediment loss and erosion Information is also provided on maintenance of the control devices as well as what should be checked during required inspections. BMP SELECTION GUIDE Erosion Control These BMPs protect the soil before erosion occurs. They are primarily used around areas of construction to either limit the flows across the site or limit the erosion in areas distributed but not active. BMP Name Primary Purpose Rating Interceptor Swale Diversion Dike Pipe Slope Drain Vegetation Mulching Erosion Control Mats Route flows around areas of disturbance Route flows around areas of disturbance Route overland flow on a slope into a pipe to protect the slope Provide natural soil protection through seeding, hydromulch or phasing Protect disturbed soil with a layer of hay Protect disturbed soil or slopes with geotextile and biodegradable fabrics Very Effective Very Effective Effective Very Effective Very Effective Effective SEDIMENT LOSS PREVENTION Construction activities normally result in disturbance on the site dueto grading operations, clearing and other operations. Erosion will occur in these disturbed areas and BMPs must be used to contain the sediment from these disturbed areas. The following techniques reduce soil loss from the site by retaining the soil through sedimentation or filtration of the runoff. BMP Name Silt Fence Straw Bales Primary Purpose Slow and filter runoff to retain sediment Slow and filter runoff to retain sediment Rating Effective Effective Sediment Basin Large pond with controlled outflow which allow sediment to settle out of runoff Very Effective and strongly recommended for sites larger than 10 acres Temporary Sediment Tank Stabilized Construction Entrance Sandbag Berm Provide sedimentation for sediment laden runoff from trenches and depressed areas Reduces offsite sediment tracking from trucks and construction from equipment Provide sedimentation and filtration for runoff under concentrated conditions in creeks, channels and drainage swales Effective for specialized application Moderate Effectiveness but required to address offsite tracking Effective for severe applications WASTE MANAGEMENT These techniques will be used on the majority of construction projects due to their general topic of reducing waste from construction activities. They form the basis of general housekeeping procedures which should be followed during construction. BMP Name Solid Waste Mange Hazardous Waste Management Concrete Waste Management Primary Purpose Techniques for management of paper, packaging, general building materials, etc. Management of paints, chemicals, fertilizer, oil and grease, etc. Disposal of concrete washout, demolished concrete, etc. Rating Very Effective Very Effective Very Effective Interceptor Swale Description An interceptor swale is a small v -shaped or parabolic channel which collects runoff and directs it to a desired location. It can either have a natural grass lining or depending on slope and design velocity, a protective lining of erosion matting, stone or concrete. Primary Use The interceptor can either be used to direct sediment laden flow from the disturbed areas into a controlled outlet or to direct `clean' runoff around disturbed areas. Since the swale is easy to install during early grading operations, it can serve as the first line of defense in reducing runoff across disturbed areas. As a method of reducing runoff across the disturbed construction area, it reduces the requirements of structural measures to capture sediment from runoff downstream of the disturbed area, runoff can be directed into a sediment basin or protect inlet for sedimentation as opposed to long runs of silt fence, hay bales or other filtration method. Based on site topography, swales can be effectively used in combination with diversion dikes. Applications Common applications for interceptor swales include roadway projects, site development projects with substantial offsite flow impacting the site and sites with large area of disturbance. It can be used in conjunction with diversion dikes to intercept flows. Temporary swales can be used throughout the project to direct flows from staggering areas, storable and fueling areas along with specific areas of construction. Note that runoff which crosses disturbed areas or is directed in unstable swales must be routed into a treatment BMP such as a sediment basin. Grass lined swales are an effective permanent stabilization technique. The grass effectively filters both sediment and other pollutants while reducing velocity. Design Criteria ▪ Maximum depth of flow in the swale shall be 1.5 foot based on 2 year design storm peak flow. Positive overflow must be provided to accommodate larger storms. • Side slopes of the swale shall be 3:1 or flatter. ▪ The minimum required channel stabilization for grades less than 2 percent and velocities less than 6 feet per second shall be grass. For grades in excess of 2 percent or velocities exceeding 5 feet per second, stabilization in the form of high velocity erosion control mats, 3" layer of crushed stone or rip rap is required. Velocities greater than 12 feet per second will require approval by the local jurisdiction and is discouraged. • ■ Check dams can be used to reduce velocities in steep swales. See check dam BMP for design criteria. Interceptor swales must be designed for flow capacity based on Manning's Equation to insure a proper channel section. Alternate channel sections may be used when properly designed and accepted. • Consideration must be given to the possible outlet. ▪ Swales must maintain positive grade to an acceptable outlet. Limitations Interceptor swales must be stabilized quickly upon excavation so as not to contribute to the erosion problem they are addressing. Swales may be unsuitable to the site conditions (too flat or steep). Limited flow capacity for temporary swales. For permanent, the 1 foot maximum depth can be increased as long as long provisions for public safety are implemented. Maintenance Requirements Inspection must be made after each significant (0.5" or greater) rain event to locate and repair any damage to the channel or to clear debris or other obstructions so as not to diminish flow capacity. Damages from normal construction activities or storms such as tire ruts or disturbance of stabilization of the swale shall be repaired as soon as practical. Diversion Dike Description A diversion dike is a compacted soil mound which redirects runoff to a desired location. The dike is typically stabilized with natural grass for low velocities or with stone or erosion control mats for higher velocities. Primary Use The diversion dike is normally used to intercept offsite flow upstream of the construction area and direct the flow around the disturbed soils. It can also be used down stream of the construction area to direct flow into a sediment reduction device such as a sediment basin or protected inlet. The diversion dike serves the same purpose and, based on the topography of the site, can be used m combination with an interceptor swale. Applications By intercepting runoff before it has a chance to cause erosion, diversion dikes are very effective in reducing erosion at a reasonable cost. They are applicable to a large variety of projects including site developments and linear projects such as roadways and pipeline construction. Diversion dikes are normally used as perimeter controls for construction sites with large amounts of offsite flow from neighboring properties. Used in combination with swales, the diversion dike can be quickly installed with a minimum of equipment and cost, using the swale excavation as the dike. No sediment removal technique is required prior to crossing disturbed areas. Significant savings in structural controls can be realized by using diversion dikes to direst flow to central area such as a sedirnent basin or other sediment reduction structure if the runoff crosses disturbed areas. Design Criteria ▪ The maximum contributing drainage area should be 10 acres or less depending on site conditions. a Maximum depth of flow at the dikes shall be 1 foot. The maximum width of the flow at the dikes shall be 20 feet. ▪ Side slopes of the diversion dike shall be 3:1 or flatter. a Minimum width of the embarkment at the top shall be 2 feet. ▪ Minimum embarkment height shall be 18 inches as measured from the toe of slope on the upgrade side of the berm. • For velocities of less than 6 feet per second, the minimum stabilization for the dike and adjacent flow areas is grass or erosion control mats. For velocities greater than 6 feet per second, stone stabilization or high velocity erosion control mats should be used. Velocities greater than 12 feet per second must be approved by the local jurisdiction. • The dikes shall remain in place until all disturbed areas which are protected by the dike are permanently stabilized unless other controls are put into place to protect the site. Limitations Compacted earth dikes require stabilization immediately upon placement so as not to contribute to the problem they are addressing. The diversion dike can be a hindrance to construction equipment moving on the site, therefore their locations must be carefully planned prior to installation. Maintenance Requirements Dikes must be inspected on a regular basis to determine if silt is building up behind the dike, or if erosion is occurring on the face of the dike, Silt shall be removed in a timely manner. If • erosion is occurring on the face of the dike, the slopes of the face shall either be stabilized through mulch or seeding or the slopes of the face shall be reduced. Pipe Slope Drain • Description A pipe slope drain is a temporary pipe line typically utilizing flexible pipe that conveys runoff down unstable slopes. They are anchored on each end with some form of headwall to limit erosion and secure the pipe. Primary Use A pipe slope drain is used on sites with a long, unstable slope area which is subject to erosion from overland flow crossing unstable or poorly stabilized sloped areas. It is normally used in combination with interceptor swales or diversion dikes to direct the flow into the pipe area. The pipe slope drain can provide service for a relatively large area. It does not treat the runoff, therefore if the runoff contains sediment, treatment through a controlled outlet will be required before the flow is released offsite. Applications Sites with large berms or grade changes such as roadway embankments are candidates for a pipe slope drain. Since provisions must be made to direct the flow into the pipe drain, some grading is normally required upstream of the pipe slope drain. Installed properly, slope erosion can be greatly reduced (but not entirely eliminated) through the use of the drain. Pipe slope drains also require a stabilized outlet. This is critical since the velocities at the outfall are normally high. Velocity dissipaters as well as stone or concrete rip rap are typically required to reduce the velocity and spread the flow, reducing erosion. Flow from a pipe slope drain should be routed to a controlled outlet through interceptor swales, diversion dikes or other suitable methods. Design Criteria • The entrance to the pipe slope drain shall be a standard pre -fabricated flared end section with an integral toe plate extending a minimum of 6 inches from the bottom of the end section. The grade of the entrance shall be 3 percent maximum. ■ AU sections of the pipe slope drain shall be connected using watertight collars or gasketed watertight fittings. ▪ All sediment -laden runoff conveyed by the pipe scope drain shall be directed to sediment trapping facility. ▪ Temporary pipe slope drains are to be sized to accommodate runoff flows equivalent to a 10 year storm as calculated using the Rational Method and Manning's equation, but in no case shall . i. es be sized smaller than is shown in the followin • table: Minimum Pipe Size 12" 18" 21" Maximum Contributing Drainage Area 24" 30" 0.5 Acres 1.5 Acres 2.5 Acres 3.5 Acres 5.0 acres ▪ Maximum drainage area for individual pipe slope drains shall be 5 acres. For areas larger than 5 acres, additional drains shall be added. • Both the entrance and out fall of the pipe slope drain should be properly stabilized. Grass can normally be used at the entrance, but armor type stabilization such as stone or concrete rip rap is normally used to address the high velocities of the outfall. Limitations • Drains must be located away from the construction areas since the drain can easily be damaged by construction traffic. • Securing the pipe to the slope can be difficult and require significant maintenance during the life of the system. ▪ In situations where pipe slope drains convey sediment -laden runoff, pipes can become clogged during large rain events causing water to overtop the diversion dike thereby creating a serious erosion condition. • Grading is normally required upstream of the pipe slope drain in order to direct flow into the system. This can cause additional cost and maintenance. A pipe slope drain reduces erosion but does not prevent it or reduce the amount of sediment runoff. Additional measures should be used in conjunction with the pipe slope drain to treat the flow. Maintenance Requirements Inspection must be made of the pipe after each sufficient (> 0.5 inch) rain event to locate and repair any damage to joints or clogging of the pipe. In cases where the diversion dike has deteriorated from around the entrance of the pipe, it may be necessary to reinforce the dike with sandbags or to install a concrete collar to prevent failure. Signs of erosion around the pipe drain should be addressed in a timely manner by stabilizing the area with erosion control mats, crushed stone, concrete or other acceptable methods. Vegetation Description Vegetation, as a Best Management Practice, is the sowing of annual grasses, small grains or legumes to provide interim vegetation stabilization for disturbed areas. Primary Use Vegetation is used as a temporary or permanent stabilization technique for areas disturbed by other structures. As a temporary control, vegetation is used to stabilize stock piles and barren areas which are inactive for long periods of time, As a permanent control, grass and other vegetation provide for good protection for the soil along with some filtering for overland runoff. Subjected to acceptable runoff velocities, vegetation can provide a good method of permanent storm water management as well as a visual amenity to the site. Vegetation can be used in conjunction with other techniques in order to assist in establishment of the vegetation. These other techniques include erosion control matting, swales and dikes to direct flow around newly seeded areas and proper grading to limit runoff velocities during construction. Applications Vegetative techniques can and should apply to every construction project with few exceptions. Vegetation effectively reduces erosion in swales, stock piles, berms, mild to medium slopes and along roadways. Vegetative strips can provide some protection used as a perimeter control for utility and site development construction. In many cases, the initial cost of temporary seeding may be prohibitive for stockpiles or other barren areas subject to erosion yet inactive. This initial cost should be weighed with the amount of time the area is to remain inactive, since maintenance cost for vegetated areas is much less than most structural controls. Design Criteria Surface Preparation ▪ Interim or final grading must be completed prior to seeding, minimizing all steep slopes. • Install all necessary erosion structures such as dikes, swales, diversions, etc., prior to seeding. ▪ Groove or furrow slopes steeper than 3:1 on the contour line before seeding. ▪ Seed -bed should be well pulverized, loose and uniform. O Plant Selection, Fertilization and Seeding a Use only high, USDA certified seed. ▪ Use an appropriate species or species mixture adapted to local climate, sail conditions and season according to the following table. Consult with the local office of the U.S. Soil Conservation Service (SCS) or Engineering Extension service as necessary for the selection of proper species and application technique in this area. ■ Seeding rate should be in accordance with the following table or as recommended by the SCS or engineering extension service. ▪ Fertilizer shall be applied according to the manufacturer's recommendation with proper spreader equipment. Typical application rate for 10-10-10 grade fertilizer is 700-1000 lb/acre. DO NOT OVER APPLY FERTILIZER. a If hydro -seeding is used, do not mix seed and fertilizer more than 30 minutes before application. ▪ Evenly apply seed using cyclone seeder, seed drill, or hydro seeder. ■ Provide adequate water to add in establishment of vegetation. ▪ Use of appropriate mulching techniques. • • Limitations Vegetation is not appropriate for areas subjected to heavy pedestrian or vehicular traffic. As a temporary technique, vegetation may be costly when compared to other techniques. Vegetation is not appropriate for rock, gravel or course grained soils unless 4"-6" is applied. Maintenance Requirements Protect newly seeded areas from excessive runoff and traffic until established. A watering and fertilizing schedule will be required as part of the SWPPP to assist in the establishment of the vegetation. Mulching Description Mulching is a layer of straw or other material which is spread uniformly over barren areas to reduce the effects of erosion from rainfall. Types of mulch include organic materials, straw, wood chips, bark or other fibers, decomposed granite, and gravel. Primary Use Mulch is used to temporarily and/or permanently stabilize clear or freshly seeded areas. It protects the soil from erosion and moisture loss by leasing the effects of wind, water, and sunlight. It also decreases the velocity of sheet flow, thereby reducing the volume of sediment- laden water flow leaving the mulched area. Applications Mulch may be used on any construction -related disturbed area for surface protection including: Freshly seeded or planted areas, Areas at risk due to the time period being unsuitable for growing vegetation, Areas that are not conductive to seeding or planting. Design Criteria Mulch may be used by itself or in combination with netting or other anchors to promote soil stabilization. Several manufactures provide organic mulch with an attached netting to simplify installation. Installation requirements should adhere to manufacture's specifications and requirements. Choice of mulch depends largely on slope, climate, and soil type in addition to availability of different materials. Straw and hay are the recommended choice due to their availability and biodegradability. Mulch should be applied in an even and uniform manner where concentrated water flow is negligible. In the North Central Texas area, the application of mulch should be approximately 2 tons dry per acre spread uniformly across the disturbed area. For areas using straw mulch and the slope is greater than 3-5 %, anchoring of the mulch with a Krimper Tool is required. Limitations Mulches are subject to removal by wind or water under severe climatic conditions. Mulches lower the soil temperature which may result in longer seed germination periods. Maintenance Requirements Mulched areas must be inspected on a weekly basis, and after significant rainfall, for thin or bare spots caused by natural decomposition or weather related events. Mulch in high traffic areas should be replaced on a regular basis to maintain uniform protection. Erosion Control Mats Description An Erosion Control Mat (ECM) is a geotextile or biodegradable fabric placed over disturbed areas to limit the effects on erosion due to rainfall impact and runoff across barren soil. Erosion control mats are manufactured by a wide variety of vendors addressing a wide variety of conditions such as vegetation establishment and high velocity flow. Types of matting include organic (jute, straw) and synthetic (excelsior and fiber glass) materials. Primary Use Mats can be provided both temporary and/or permanent stabilization for disturbed soil or barren areas. It is used for difficult to stabilize areas such as steep slopes, temporary or permanent drainage swales, embankments or high traffic (pedestrian) areas. Some mats are reusable, reducing the initial cost of the instillation. Applications Mats can be used on any construction -related disturbed area, but are particularly effective for erosion control of fine grained soils, and on short, steep slopes (such as stream banks) where erosion is high and growth of vegetation is slow. Design Criteria A mat may be used by itself or in combination with netting other anchors to promote soil stabilization. Choice of matting depends largely on slope, climate, soil type, and durability. Mats are usually installed to the manufacturer's recommended guidelines. After appropriate instillation, the matting should be checked for: uniform contact with the soil; security of the lap joints; and flushness of the staples with the ground. Manufacturers information will verify acceptable applications for a particular product. Limitations Although matting is highly effective in controlling erosion, it may be Iess cost-effective than other BMPs for erosion control and it requires a contractor with considerable mat installation experience for installation. Maintenance Requirements Matted areas must be inspected on a weekly basis, and after significant rainfall, for bare spots caused by weather related events. Missing or loosened matting must be replaced or re- • • • anchored. Silt Fence Description A silt fence consists of geotextile fabric stretched between either wooden or metal posts with the lower edge of the fabric securely embedded in the soil. The fence is typically located downstream of disturbed areas to intercept runoff in the form of sheet flow. Silt fence provides both filtration and time for sedimentation to reduce sediment and it reduces the velocity of the runoff. Properly designed silt fence is economical since it can be relocated during construction and reused on other projects. Primary Use Silt fence is normally used as a perimeter control for downstream of construction sites. It is only feasible for non -concreted, sheet flow conditions. Applications Silt fence is an economical means to treat overland, non -concentrated flows for all types of projects. Silt fences are used as perimeter control devices for both site developments and linear (roadway) type projects. They are most effective with coarse to silty soil types. Due to the potential of clogging, silt fence should not be used with clay soil types. In order to reduce the length of the silt fence, it can be placed adjacent to the downstream side of the construction activities. Design Criteria 2 Fences are to be constructed along a line of constant elevation (along a contour lime). a Maximum slope adjacent to the fence is 1:1. • Maximum distance of flow to the silt fence shall be 150 feet. • Maximum concentrated flow to silt fence shall be 1 CFS. • If 50% or less of the soil, by weight, passes the U.S. Standard sieve No. 200, Select the Equivalent Opening Size (E.O.S.) to retain 85% of the soil. ▪ Maximum EOS shall be 70 (#70 sieve), ▪ Minimum EOS shall be 100 (#100 sieve). ■ If 85% or more of soil, by weight, passes the U.S Standard sieve No. 200, silt fences shall not be used due to clogging. • Sufficient room for the operation of sediment removal equipment shall be provided between the silt fence and other obstructions in order to properly maintain the fence. • The ends of the fence shall be turned upstream to prevent bypass of storm water. Limitations Minor ponding will occur at the upstream side of the silt fence resulting in minor localized flooding. Fences which are not constructed on a level contour will be overtopped by concentrated flow resulting in failure of the filter fence. Silt fences subject to areas of concentrated flow (waterways with flows > 1 cfs) are not acceptable. Silt fence can interfere with construction operations, therefore planning of access routes onto the site is critical. Silt fence can fail structurally under heavy storm flows, creating maintenance problems and reducing the effectiveness of the system. Maintenance Requirements Inspections should be made on a regular basis, especially after a large storm events. If the fabric becomes clogged, it should be cleaned or if necessary, replaced. Sediment should be removed when it reaches approximately one-half the height of the fence. • Straw Bale Dike Description A straw bale dike is a temporary barrier constructed of straw bales anchored with wood or steel posts, which is used to intercept sediment -laden runoff generated by small disturbed areas. The hay bales can serve as both a filtration device and a dam/dike device to treat and redirect flow. Primary Use A straw bale dike is used to trap sediment -laden storm runoff from a small drainage areas with relatively level grades, to allow for reduction of velocity thereby causing sediment to settle out. Applications Straw bale dikes are used to treat flow after it leaves a disturbed area on a relatively small (< acre) site. Due to the limited life of the hay bale, it is cost effective for small projects of a short duration. The limited weight and strength of the hay bales makes it suitable for small, flat (<2 percent slope) contributing drainage areas. Due to the problems with the straw degradation and The lack of uniform quality in hay bales, their use is discouraged except for small residential application. Straw bales can also be used as check dams for small watercourses such as interceptor swales and borrow ditches. Due to the problems in securely anchoring the bales, only small watercourses can effectively use hay bale check dams. Design Criteria ▪ Straw bale dikes are to be constructed along aline of constant elevation (along a contour line). ▪ Straw bale dikes are suitable only for treating sheet flows across grades of 2% or flatter. ■ Maximum contributing drainage area shall be 0.25 acre per 100 linear feet of dike. • Maximum distance of flow to dike shall be 100 feet. ■ Dimensions for individual bales shall be 30 inches minimum length, 18 inches minimum height, 24 inches minimum width and shall weigh no less than 50 pounds when dry. ■ Each straw bale shall be placed into an excavated trench having a depth of 4 inches and a width just wide enough to accommodate the bales themselves. ▪ Straw bales shall be installed in such a way that there is no space between bales to allow for any kind of seepage. • Individual bales should be held in place by no less than two wood or steel stakes driven a minimum distance of 6 inches into undisturbed ground, with the first stake driven at an angle toward the previously installed bale. ▪ The ends of the dike shall be turned upgrade to prevent bypass of storm water Limitations Due to a short effective life caused by biological decomposition, straw bales must be replaced after a period of no more than 3 months. During the wet and warm seasons, however, they must be replaced more frequently as is determined by frequent inspections. Straw bale dikes are not recommended for use with concentrated flows of any kind except for small flows in which they can serve as a check dam. The effectiveness of straw bales in reducing sediment is very limited. Improperly maintained, straw bales can be a negative impact on the water quality of the runoff. Maintenance Requirements • Straw bales shall be replaced if there are signs of degradation such as straw located down stream from the bales, structural deficiencies due to rotting straw in the bale or other signs of deterioration. Sediment should be removed from behind the bales when it reaches a depth of approximately 6 inches. If the bales become clogged they should be replaced immediately Sediment Basin Description A sediment basin is a pond area with a controlled outlet in which sediment -laden runoff is directed to allow settling of the suspended sediment from the runoff. It provides treatment for the runoff as well as detention and controlled release of runoff, minimizing flood impacts downstream. Primary Use Sediment basins should be used for all sites with adequate open space to site the basin. for sites with disturbed areas of 10 acres and larger in a common drainage area sediment basins are required as either temporary or permanent controls unless specific site conditions limit their use. Applications Sediment basins serve as treatment devices which can be used on a variety of project types. It is normally used in site development projects in which large areas of land are available for the basin, a stream or drainage way crosses the site, or a specific water feature is planned for the site. Sediment basins are highly effective for the design storm conditions. It is also reduces maintenance requirements due to the central location of the sediment and minimal structural requirements of the basin. Design Criteria • Maximum drainage area contributing to the basin shall be 100 acres. • Minimum drainage of the basin shall be 3600 cubic feet per acre of contributing drainage area. • Deposited sediment shall be removed when the storage capacity of the basin has been depleted by one-half. ▪ Minimum width of the embankment at the top shall be 8 feet. • Minimum embankment slope shall be 3:1. • Maximum embankment height shall be 6 feet measured from the toe of slope on the downstream side. • The basin outlet shall be designed to accommodate a 10 year design storm without causing damage to the containment structure. • Minimum outlet capacity shall be 0.2 CFS per acre of contributing drainage area. • The basin must be laid out such that the effective flow length of the basin should be at least twice the effective flow width. A design worksheet is provided in Appendix A based on U.S. Soil Conservation Service TR -55 for proper design of sediment basin. Limitations Sediment basins can be rather large depending on site conditions, requiring the use of expensive development area and comprehensive planning for construction phasing prior to implantation. Storm events which exceed the design storm event can cause damage to the spillway structure of the basin. Maintenance Requirements Sediment shall be removed and the basin shall be regarded to its original dimensions at such point where the capacity of the impoundment has been reduced to one-half of its original storage capacity. The removed sediment shall be stockpiled or redistributed in areas which are protected from erosion. The basin outlet structure and emergency spillway (if present) should be checked frequently and after each major rain event to check for damage and to insure that obstructions are not diminishing the effectiveness of the structures. Sand Bag Berm Description Sandbag berms consist of stacked sandbags installed across a watercourse to direct flow downstream of disturbed areas. There are overflow pipes located in the top of the berm to allow controlled outflow of water after sedimentation has occurred. Primary Use A sandbag berm is a temporary sediment control method that address the problem of construction in creeks, channels and other watercourses which carry a constant flow and is subjected to high, concentrated flows. A sandbag berm can also be used to create a small sedimentation pond prior to the completion of a permanent detention basin. Sandbag berms can be used as check dams in temporary swales or borrow ditches. Sandbag berms are not suitable for typical perimeter controls where sheet flow is prevalent. Applications During utility or any type of construction in channels or stream beds, sandbag berms can be used as check dams across channels or stream beds, sandbag berms can be used as check dams across channels, serve as a barrier for utility trenches or even provide a temporary channel crossing for construction equipment without seriously affecting stream conditions. Sandbag berms can also be installed parallel to the road providing a corridor of sediment control similar to that provided by a silt fence or hay bales with the exception that a sand bag dike is capable of controlling much higher flows and is much more durable. For site construction sandbag berms can be used to divert or direct flow or create a temporary sediment basin with the added dimension of being able to be moved to accommodate changes in construction much more easily than compacted earth berms. Design Criteria ▪ Dikes are to be constructed along ▪ Maximum flow through rate shall • Minimum height shall be 18 inche ▪ Minimum width of the berm shall bottom. ■ Maximum side berms shall be 2:1. • Sandbags shall consist of polypropylene, polyethylene or polyamide woven fabric with a minimum unit weight of 4 ounces per square yard, a mullen burst strength of 300 psi minimum and ultraviolet stability exceeding 70 percent, and shall be filled with coarse sand or pea gravel. ▪ 4" diameter SDR -35 or greater PVC pipe segments approximately 24 inches in length shall be used immediately below the top layer of sandbags to allow for overflow of the berm. i For severe velocities or high flows, woven mesh wire can be used to maintain the integrity of the berm. ▪ Sufficient room for the operation of sediment removal equipment shall be provided between the berm and other obstructions in order to properly remove sediment. ▪ The ends of the berm shall be turned upgrade or shall tie into natural grades to prevent bypass of stormwater, level contours for use as perimeter control devices. be 0.1 CFS per square foot of berm surface. s. be 18 inches at the top and 48 inches measured at the Limitations Sandbag berms are a costly, labor intensive technique which is suitable only for areas subjected to high concentrated flows. The permeability of the berms makes it unsuitable for low flow, perimeter conditions. Ponding will occur directly upstream from the berm creating the possibility of a flooding concern which should be considered prior to its placement. For sandbag berms located in high flow areas such as a creeks, the potential for berm damage during high flow increases the requirement for maintenance. Maintenance Requirements Inspections should be made on a daily basis and after each rain event. The sandbags shall be reshaped or replaced as needed during the inspection. Silt should be removed when it reaches a depth of six (6) inches. In addition, regular inspections should be made on the PVC pipe segments to assure clear flow. • • INSPECTION REPORT Area Inspected Date Name of Inspector Title Observa[ APPENDIX C BMP DIAGRAMS BMP DIAGRAMS w EROSION CONTROL MATS MULCHING SAND BAG BERM HAY BALE DIKE SILT FENCE SEDIMENT BASIN WATERBREAK CONSTRUCTION BROAD BASED DRAINAGE DIP CULVERT CONSTRUCTION LOW WATER CROSSING • DRAINAGE DIP • EROSION CON -IRO! fotATS _1 DISTURBED SOIL • =1 Erosion Contol Mots FILE BUYS \E-6 DRAFTED 9Y: DOC DATE: 2/14/Q7 • FLOWUNE OF CHANNEL OR SWALE FIE BUYS \S -B DRAFTED BY: DDG DATE 2/ 17 /97 HOT TO SCALE Sand Bag Berm FLOW FLOW ' :1:41:4:1l I ""' t:I1:1:wI:1: 4" VERTICAL FACE EMBEDDING DETAIL TWO STAKES PER BALE (STAKES 6' MIN. 1N GROUND) ANGLE FIRST STAKE TOWARD PREVIOUSLY LAID BALE 1:1'x1 ; I :,j, :1:1',41:1: 11 .:1:it) :1.:i,l;y 1X11 :1:1+1 : I ' r : I's I : I : 1s 1 : 1 :'F' y'l:i:i:l:l:l:l: : :1:1:11:1:1:1.1.,.

Prepared by: WestWater Engineering, Inc, 2516 Foresight Circle #1 Grand Junction, CO 81505 970-241-7076 January 2007 Middle Fork Compressor Station Integrated Vegetation and Noxious Weed Management Plan January 2007 Introduction This plan is for compliance with Condition No. 4; parts a, b and c; Resolution No. 2005-85; November 7, 2005; Board of County Commissioners (BOCC, 2006), Garfield County. The plan is for the Middle Fork Compressor Station on North Parachute Ranch (NPR) on County Road 215 (Map; Figure 2, attached). On January 4, 2007, a field inspection of the site was conducted by WestWater Engineering (WWE) biologists. The inspection identified appropriate topics for inclusion in an integrated vegetation and noxious weed management plan. Factors considered include soil type and texture, existing land management, absence or presence of listed noxious weeds, and potential natural vegetation community. The site was previously a portion of an oil shale retort complex. It is adjacent to a produced water treatment facility, tank farm, and staging area for equipment, parts and supplies. High use roads surround the site. Field conditions were poor to conduct the inspection with snow covering much of the site and surrounding terrain (Photo 1, page 1). Snow cover precluded a thorough survey for rosettes of weeds that may hinder re -vegetation. WWE biologists have spent considerable time conducting studies of sensitive plants and wildlife on other NPR projects and, as a result, are able to make recommendations in this plan, which are appropriate to the site. Landscape Setting The Middle Fork Compressor Station is located on the first terrace above East Fork Parachute Creek at the toe of the cliffs and escarpment formed of the Green River Formation. The site is relatively flat but terrain quickly rises to rock escarpments immediately north of the complex. Medium textured Nihill channery loam soils are present but were not segregated prior to industrial construction and disturbance. This series is deep, well -drained and usually derived from alluvium (NRCS, 2007). The site has an obvious colluvial component due to erosion of the escarpment. Characteristic natural vegetation includes western wheatgrass (Pascopyrum smithii), big sagebrush (Artemesia tridentata spp.), bluebunch wheatgrass (Pseudorogneria spicata spicata), Indian ricegrass (Achnatherum hymenoides), needleandthread (Hesperostipa comata) and yellow rabbitbrush (Chrysothamnus viscidifloris) (NRCS, 2006b). Undisturbed slopes adjacent to the compressor station were found to have predicted vegetation including sagebrush-rabbitbrush shrubland east of the site (Photo 2) and mixed salt desert shrubland on the steep slope north of the station (Photo 3). Predicted grass species were also present in low density. A native thistle, Cirsium barnebyi was found on the cut slope of the Long Ridge road approximately 100 meters above the site. This native thistle is not invasive and should not be controlled or treated. WestWater Engineering M. F. Compressor Station IVNWMP Page 1 of 11 Photo 2. Rabbitbrush east of compressors. Photo 3.

The noxious weeds in the vicinity have been receiving treatment but are found in low density in most cases. Total, non-selective, vegetation control is recommended within the perimeter of the 3 acre compressor station for practical and safety reasons. Newer non-selective herbicides such as DuPont Sahara® are formulated to reduce migration and leaching into non -target areas and require very low amounts of an active ingredient, which decreases probability of bio - accumulation in non -target species. Temporary disturbance of the perimeter is recommended to be reclaimed with the recommended seed mix and spot treated with selective herbicides or mechanical control if noxious weeds invade, all of which are described in the appropriate sections of this report. Targeted Weeds: Although not currently found on the compressor site, Table 1 lists weeds nearby and those most likely subject of future control efforts within and around the site.

(State of Colorado, 2005) **A=annual, 13 -biennial, and P=perennial. The strategies summarized in Table 2 for annuals and biennials and in Table 3 for perennials are those found to be most effective depending on the growth habits of each species, i.e., annual, biennial, or perennial. This information is contained herein to emphasize the importance of knowing for certain the species of weeds present. Table 2. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production I. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds develop. crit and bag seed heads. 2. Chop roots with a spade below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. Table 3. 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 M. F. Compressor Station IVNWMP Page 4 of 11 Table 3. 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 eer present efficiently atthistperiodeoftitme, another season of nslocation of seed production is not ass to roots rather than important mport nt as getting ves. If the weed patch has been present for a long p the herbicide into the root system. Spraying in fall (after middle August) will kill the following years shoots, which are being formed on the roots at this time. 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 112" - 1" long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless it is known the plants are seedlings and I not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must 4 be done repeatedly. - Best Management Practices The following practices should be adopted for any construction project to reduce the costs of noxious weed control. The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, • in all cases temporary disturbance should be kept to an absolute minimum, • equipment and materials handling should be done on established sites, • disturbances should be immediately replanted with the recommended mix in the re - vegetation section. In areas with slope greater than 3%, 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 hydro - seeding or 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: Herbicide treatment in fall (after approximately August 15 when natural precipitation is present) is the best method to control difficult perennials such as Canada thistle. Difficult species respond better to application of a combination of two or more chemical modes of action (biological reason for plant death) rather than one. Local certified commercial herbicide applicators report best control of Canada thistle using a combination of modes of action. It has also been found that use of two different groups of chemicals in the same mode of action can increase effectiveness on difficult species, e.g. phenoxys and benzoic acids or carboxylic acids and benzoic acids in a mix. Some come commercially pre -mixed, e.g. Crossbow® and Super Weed -be -Gone Max® which are available over the counter. Many of the most effective herbicides are restricted use and available only for licensed applicators. WestWater Engineering M. F. Compressor Station IVNWMP Page 5 of 11 Professionals or landowners using herbicides must use the concentration specified on the label for the target species. Herbicides generally do not work better at higher concentrations. Label restrictions and formulations must be adhered to for compliance with regulations. Most herbicide applications should use a surfactant as directed on the herbicide label or other adjuvants as called for on the herbicide label. Grazing: There is no grazing of domestic animals. Evidence of grazing by mule deer, Odocoileus hernionus, is very low and not of sufficient intensity to affect reclamation. Mechanical: It is recommended senescent, seed -bearing, listed weeds be cut, bagged and disposed of in a licensed landfill (Photos 4 and 5). Rosettes can be cut with a shovel below the surface of the soil on plants which are not yet dormant (Photos 6 and 7). Even with some seed drop, cutting and bagging will greatly reduce seed release. Future need to do mechanical or other control methods should be reduced after only two seasons of cutting and bagging. Photo 4. Seed bearing burdock. Photo 6. Houndstongue rosette. WestWater Engineering Photo 5. Seed bearing musk thistle. Photo 7. Musk thistle rosette. M. F. Compressor Station IVNWMP Page 6 of 11 Alternative Methods Some noxious weeds are subject to damage from beneficial insects. Included are Canada thistle stem mining beetle, Ceutorhynchus litura; Canada thistle bud weevil, Larinus planus; musk and plumeless thistle rosette weevil, Trichosirocalus horridus; Canada thistle stem gall fly, Urophora cardui; and thistle defoliating beetle, Cassida ruhiginosa, which feeds on the foliage of Canada, musk and plumeless thistles (Sullivan, 2004). Currently, the thistles present are not of sufficient density, in the opinion of WWE, to support populations of insect parasites. Therefore, it is unlikely these insects would be helpful unless explosive spread and growth occurs in the future. The bindweed mite, Acerin malherbae, is a microscopic mite imported from southern Europe as a biological control agent for field bindweed (Hammon, 2006). According to recent anecdotal information, it may be a very effective control for bindweed. This mite may be useful for reducing field bindweed infestations which can become highly invasive in the vicinity. Another alternative method, particularly for cheatgrass infestations and poor to non-existent topsoils, is the application ofvesicular-arbuscular mycorrhizal fungi (V/AMF). These fungi, mostly of the genus Glomus, are symbiotic with about 80% of all vegetation. 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 V/AMF or AMF commercial products, which are better adapted to coating seeds when reseeding 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 applicators, including a New Castle company, collect and grow local accessions of V/AMF. The latter are applied to weed patches and are reputed to greatly increase competition of native plants, with Canada thistle in particular, thereby affecting a non -chemical control of some noxious weeds. Re -vegetation Soil types on the property generally support many of the same species of native vegetation, The following seed mix is from the reclamation plan developed for NPR by WWE (Table 4): Table 4.

Preferred seeding method is hydro seeding or multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and waterbars. Seed should be bagged separately so each size group of seed can be metered at the appropriate rate. 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, • 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. Life Cycle and Manaeement Calendars Figure 1 is a 2 -year calendar for control and life cycle of biennial thistles. Not included is mechanical control, which is cutting of rosettes below the soil surface and can be done any time during the rosette stage. Figure 1.

Encana has asked WestWater Engineering to provide recommendations that will facilitate initial re -vegetation and re-establishment of natural succession of native plant species. This plan is based on the combined knowledge of W e tWater's biologists (Michael W. Klish, Rusty Roberts and Bill Clark), who have personal experience in the project arca vicinity that spans more than 30 years each, and available literature provided in the reference section. Encana's land use objcctt.0 for tlw North Paiachute Ranch is to re-establish a self-sustaining vegetation cover integrated with the surrounding ecosystems. The plan is a "working document,. and subject to amendment and revision based upon new information and changes in land use at NPR. The recommendations included herein apply to disturbances on upland plant communities. Recommendations for wetland habitats ale nut included as disturbance to these plant communities are expected to be minimal. This docutiient our. ides recommendations for the t-ollow ing inajor subject areas: (1) Reclamation Challenges and Critical Arca Avoidance (2) Reclamation (3) NPR Seed Mixtures (4) Reclaination Monitoring lig%CKG ROL ND Climatic lanes within the NPR There are three climatic zones within the NPR and are referred to as the Upper, Middle and Lower Zones. Similar precipitation patterns, soils and plant communities exist within the three zones. The Upper Zone consists of lands above the rimrnck escarpment of the Roan Plateau at elevations between 7,500 to 8,500 feet; excluding slopes greater than 200/o, south facing areas. The Middle Zone consists of lands between the escarptnent of the plateau to the toe of the slope along the valley floors at elevations between 7,500 and 6,000; including steep, south facing slopes above 7,500 feet. The Lower Zone consists of the lower terraces and floodplains along the valley bottoms of the major drainages below elevations of 6,000 feet. The location of NPR is shown on Figure Y (attached), a 2005 aerial photo showing the general locations of the Upper, Middle and Lower Zones. NPR Reclamation Plain i May 2006 Upper Zone The Upper Zone receives 16 to 25 inches of annual precipitation. A majority of the annual ine ipitation is received during nein-grosN itt season (late fsll.'w inter). Priinary plant communities in the Upper Zone are Mountain Big Sagebrush. Wheatgrass and Upland Deciduous ShrubWheatgrass shrublands with smaller occurrences of Aspen and Douglas Fir forests and riparian shrub. tree and wetland habitats The plant communities in the Upper Zone have the greatest diversity of plant species. Most of these species have adapted mechanisms for establishment and survival in the presence of the competition exerted by other species in the community. These communities are dominated by short-lived cool season bunch grasses, which arc an important factor in providing interspaces for establishment and maintenance of (orbs and shrubs within the community. Some of the major species in the Upper Zone are listed in the following table.

These soils are mostly well -drained, cool soils with dark -colored, organic -rich surface layers derived from shale and sandstone. Soil textures above the rim are generally Inam with loam to clay loam sub -soils and range in depth from <20' on ridges to >60" in swales. All of the upland soils above the rim are in low to medium erosion classes(BLM, 2004, Fox, ex a(., 1973). Liddle Zane The Middle Zone receives 13 to 14 inches of annual precipitation. A majority of the annual precipitation is received during non -growing season (late fall,'winter). A significant portion of this zone consists of unstable slopes that are relatively barren of any vegetation. According to Fox, et al., 1973, these barren slopes are fairly erosion resistant if undisturbed. Primary plant communities on more stable slopes are Bunchgrass'Forb Open Grassland. Upland Deciduous Shrub-Wheatgrass shrublands, Pinyon:Juniper woodlands and Douglas Fir forests. These communities are dominated by cool season bunch grasses.

Below the cliffs and talus is a zone of soils tbrmed from colluvium and Wasatch Fort -nation. Soils are shallow, poorly developed and there are many, rock outcrops and badlands. Badlands are steep, nearly barren areas dissected by many ephemeral drainages. Badlands of the Wasatch Forrnatlon content and are calcareous. Lower Tone Soils on the upper slopes of this zone have a thin, organic -rich surface layer and little development of soil horizons. Soils on lower slopes are shallow to moderately deep and are well -drained. Surface texture is loam, clay loam. or silty clay loam with variable amounts of gravel, cobbles and boulders, talus slopes and colluvial slopes below rock outcrops. Soils are moderate to highly alkaline. Sub -soils usually have higher clay Erosion hazard is usually severe (13LM, 2004). The Lower Zone receives 10 to 13 inches of annual precipitation. A majority of the annual precipitation is received during non -growing season (late fall, winter). This zone contains some of the most and 3itcs. Primary plant communities in the Lowcr Zone on benches and tcrracca are Wyoming Big Sagebrush/Wheatgrass shrublands grading to salt desert shrubs like fourwing saltbush or shadscale on the most arid sites. The floodplain communities include Basin Big Sagcbrush.'Greasewood shrublands on old floodplain terraces and streainside riparian woodlands with cottonwood or box -elder habitats.

RECLAMATION CHALLENGES AND AVOIDANCE RECOMMENDATIONS North Parachute Ranch presentsextreme reclamation challenges from a broad array of climate and geomorphological factors inherent to the site. These factors often act svnergistically and increase the negative effects exponentially. These factors include: • Steep slopes and potential tear soil movement. • Effective soil moisture issues including timing of seeding to coincide with natural precipitation. • Difficulty in re -contouring to blend with extreme slopes of natural topography. • Thin soils due to infertility from slope. exposure and soil source materials. • Slumps (instability, difficulty in holding slopes). • Difficulty preventing establishment of noxious weeds in disturbed land. • Riparian areas especially these dominated by mature cottonwoods.box-elder shrubs (due to wildlife and water quality value and lung -tenon needed to establish large trees). Such areas. if disturbed, are very likely to require more time and expense to e1Teci .'ely reclaim. For example. riparian woodland and shrubland disturbances may require installation of live plant materials in the form of containerized trees and shrubs. installation and three. years of careful oversight and watering of these woody species to insure survival is far more costly than disturbance on sites. which can be successfully re -seeded. In addition to susceptibility to erosion and sediment problems, difficult, listed noxious weeds also present a reclamation challenge of huge proportions. For these reasons. it is recommended livestock grazing be postponed indefinitely. Canada thistle on the West Fork and houndstongue on the East Fork seriously threaten riparian plant communities. Both problems are exasperated by grazing of livestock upstream from NPR property. Prudence suggests reducing the problem as much as possible and one technique for slowing the spread of invasive weeds is to remove livestock. Livestock decrease native plant abilities to compete with invasive species. Livestock can physically move weed seeds around the property in their coats or by ingesting and excreting viable weed seeds. RECLAMATION CONSIDERATIONS This section provides recommendations For actions that should be taken in conjunction with seeding of sites undergoing reclamation. Timing of Re -vegetation ►% ork Timing of re -vegetation is critical to the success of the work. Replacement of topsoil should occur just prior to re -seeding to prevent early germination and establishment of highly competitive annual weeds. In nearly all cases, re -vegetation should occur as quickly as possible NPR Reclamation Plan 5 May 2006 atter topsoiling, in order to maintain soil nutrients and microbe levels, discourage weed invasion. and control erosion. Re -seeding, should be timed to coincide immediately prier to the season of greatest precipitation. late fail. winter. Sed of many native plant species require a period of fireezinu temperatures prior to germination which ensures the seed will genninate in spring when soil moisture conditions are optitnum for establishment and survival ofthc seedling. Also. several native species. such as big sagebrush. begin their slow germination process under snow cover. Ideally. topsoil replacement should occur in late August and September followed by re -seeding in late September to early December prior to freezing soil surface. If re -vegetation occurs too early. seeds are subjected to unnecessary exposure to seed predators and spoilage. If it occurs too late (spring planting), seeds and plants may encounter insufficient moisture to genninate or to survive after germination, and will be faced with higher competition from annual weeds. Topsoil Handling Proper handling and storage of topsoil is critical to successful re -vegetation, especially in the case of re-establishing itnportant native plant species on disturbed areas. The topsoil contains soil microbes (bacteria. n'ttcorrhiza. invertebrates) and seed banks ot'viable seed for the native plants present on the site. Many native plant species depend upon the activity of soil microbes for germination in sorne instances and for establish and survival of most seedlings. Topsoil is usually stripped from a site and stored in the smallest place possible in deep, unstable piles. Stockpiling topsoil in deep, unstable piles for long periods (over 30 days) results in the loss or limitation of topsoil microbes and viable seed_ This is especially so where soils are stockpiled more than several feet in height and biological activity is diminished from lack of oxygen. Topsoil nil should he protected from erosion and weed invasion. Topsoil should he stockpiled in piles no deeper than 2 feet with stable slopes and be positioned to minimize exposure to wind and water erosion. Topsoil piles stored for longer than 30 days should be immediately seeded to provide cover to reduce erosion, provide competition for weed species, and to maintain viability of the soil fungi and microbe communities. Several fast germinating sterile cover crops rRegreen" and "Quickguard.) are commercially available that should be used for short period storage nfrnpsnrI. Topsoil stared for more than one growing season should he seeded with one of the recommended seed mixes based upon the zone the site is in. Using the recommended seed mixes on long-term storage piles will help maintain biological actin ity and provide a seed bank of viable seed. If long-term stockpiling or deep stockpiling can not be avoided, application of micorrhizal inoculants (see section below) may be beneficial. Use of Fertilizer Use of fertilizer should not be used in the reclamation of arid or semi -arid sites. These areas are typically at high risk of invasion by exotic annual weeds. almost all of which are favored by higher levels of nitrogen. Native western species are well adapted to the low fertility of soils in these areas. There are many cases of severe weed infestations, which are directly attributable to NPR Reclamation Plan 6 May 2006 addition of nitrogen. In addition to the considerable cost incurred. the routine use of fertilizer may well trigger problems with undesirable annual invaders, which can be essentially impossible: to correct. Lase of Mulch Mulch should be used only where there arc specific indications for its application, and not as a routine element in reclamation. It may be useful in wetter areas or on extremely steep areas where severe erosion potential exists. On drier upland areas there are a number of potential probleins. These include: wiekin3 of soil moisture leading to increased e,,aputatiun, alteration of carbon: nitrogen ratios, attraction of rodent and invertebrates to seed and seedling predators, and plant competition from grain or weed seeds in the mulch. Where mulch is used, it is imperative that it be retained either by mechanical crimping, application Iota t tekitier, or with netting. These materials and the time required for their application add substantially to reclamation costs. t:se of Certified Seed The two types of certified seed are '"Blue Tagged Certified Seed" and "Yellow Tagged Source Identified Seed" Certified_ Seed (Blue Tag): Seed Certification is the means of maintaining the pedigree (genetically pure seed, of a specific variety of seed. Each state has a seed certifying agency or crop improvement association that certifies seed_ Blue Tagged Certified Seed must meet high purity and germination standards and have a low weed content, usually less than 0.25 percent. Blue tagged certified seed can not contain any prohibited noxious weeds of the state of certification llt.jnv native species are now available in certified cultivars and in most cases the certitied cultivars are lower cost. Source Identified Seed (Vellocsw Totem)' There is a strong market for native plant materials, but there may not be certified ecotypes available~ due to a lack of breeding, low supply, or high cost to produce. or unreliable demand. In most cases, native plant material should be acquired from harvest areas with the same or higher latitude of the area of intended use. State seed laws only require that the actual state of origin be on the label. To receive seed from the area you designate, it is advisable to request "Source identified Seen" in order to ensure that a certification agency has verified the exact location from which the seed was harvested. Source Identified certification is in place in Colorado, New Mexico. Utah, Wyoming and Montana. Yellow tags do not guarantee that the seed is free of noxious weeds. Buyers should refer to the vendor's label for analysis and weed content, or better yet, test the seed themselves. Harvesting Local Seed Plant species commonly display considerable site adaptation and variability. Thus seed collected far from its eventual planting site often does less well than seed of the same species collected closer to the planting site. Most professional seed suppliers record the collection site. and it may be possible to choose seed that is from locally adapted plants_ if such seed is not available, the possibility of contracting with collectors to obtain local seed should be investigated. NPR Reclamation Plan 7 May 2006 Seed I esting Testing seed is the only way to insure the quality of the seed (purity and viability) and that no undesirable species are present. Purity tests will show the percentages of crop, weed and inert matter (material other than seed such as stems or chaff). and show if the percentage of each species in the mix meets the standards ordered. The tenets germination and viability are sometimes used interchanYveabty, but do not have the same meaning. A gennmation test will determine how seeds perforin under favorable conditions: however, some seeds are dormant And do not germinate even though they are still alive. Dormant seeds have the potential to germinate if donnancv is broken, usually through time and.or physiological stimulus. A viability test will show the sum of the percent germinated and percent donnant seeds in a seed lot, providing information on the potential germination of the lot. Proper seed sampling is very important. The test results received can be no better than the sample sent in. Samples should be sent to a seed lab that tests according to the standards established by the National Association of Official Seed Certification Analysts. Inoculation of Legumes Most legume seeds should be treated with coimnercia'lly available Rhi2obiurn inoculants to ensure that they arc able to make best advantage of their capabilities for nitrogen fixation. Legumes included in seed mixes are: American Fetch, Cicer's Milkvetch. Sainfoin, and Utah Sw•eemerc•h Inoculation of Sterile Soils Arbuscular mvcorrhiza (fungi) are components of live topsoil and forret symbiotic relationships with plant roots. There are two types and they are especially critical for plants in infertile soils or drought prone areas such as those found on NPR. In most cases on NPR, endomycorrhiza should be used to inoculate the soil since this is the type of fungi that associates with herbaceous and broadleafkd woody plants. ))'coniferous species such as pinyon pine, Utah juniper. or Douglas fir are prescribed in reclamation, an ectornycorrhizal fungi would also be desirable. tinproperly stored topsoil and areas with little or no topsoil should be treated with commercial mycorrhiza (Barrow, 1995). Mvcorrihiral inoculants arc available in two [bans° as a granular form for application during seeding, and as a powder for coating of seeds prior to seeding. Granular forms are typically applied at a rate or 20 lbs/acre and powder inoculents are applied to the seed at a rate of l lbs,'acre. When broadcast seeded. the granular farm must be incorporated into the soil with seed by harrowing. Determination of Pure Live Seed (PLS) Ratio lietore a seed application rate can be determined it is necessary to determine the percentage of pure live Seed (pis) in the Supplied seed. Seed may contain weed seed, seed of other species, chaff, sand, and other inert material, and broken seeds. PLS equals the percent purity times the percent germination. Most species are sold on a PLS basis, with the puce adjusted accordingly. When given a choice between buying on a PIS or bulk basis, PLS is always preferable.

Mountain big sagebrush is not included to the mixture as it is expected to repopulate disturbance from undisturbed stands (anticipated disturbances are strap linear) Sagebrush also requires a different seeding strategy (broadcast on frozen soil or on early snow cover). Activities that result in removal of areas greater than 5 acres of sagebrush, and are not within 100 feet of sagebrush to provide seed source may need to have sagebrush included in the seed mixture. t:rw, Recommended Seed Mix for Upper Zone Disturbances Species 1 Variety fc'ultivar) !

The list is provided to account for site diversity, unstable prices and availability of plants useful for reclaination. The table can be used to replace a single. unavailable species or to develop a complete seed mix. Of great importance is the soil texture adaptation information in the Appendix. Species with wide ranges of tolerance ( i.e., species with adaptation ratings of mostly twos and threes) should be selected whenever possible. It is necessary to adjust the total number of seeds planted per square foot to precipitation, soil moisture and texture. slope and aspect. In the Lower Zone and riparian terraces fewer total seeds per square foot will likely yield better results if seedling plants are not over-whetmed by total numbers of plants. In the Middle Zone of NPR, more seeds can be planted due to generally higher precipitation and better soils in localized areas. while Upper Zone precipitation and deeper soils ►4i11 successfully sustain higher numbers of seedlings per square foot. Grasses have consistently performed better than forts or shrubs in land reclamation. More species of grasses should be in a mix than forbs or shrubs except in the case of shrub -only plantings. Species selected and the number of seeds per square foot allocated to that species are based on soil, zone. and experience in similar situations with other plantings. Generally, Lower Zone and riparian arca recipes should have fewer species of plants in the mix. c.g. three grasses, one fnrh and one shrub for a total of five species in the mix. Middle Zone mixes should have a moderate number of species of plants in a mix, e.g. four grasses, two forbs and one shrub species for a total of seven specie in a mix. Upper zones can have as warty as nine species in a mix including four grasses, two or three forbs and two or three shrubs. Reclamation NlIonitoring Success of rtvegetation should be judged on the effectiveness of the vegetation for the post- developmere land use of the property, and the extent of cover compared to the i u4Gr uccurrinK in natural vegetation of the area. Projected cover of desirable species should be based on cover NPR Reclan;ation Plan 11 May 2006 tneasured in undisturbed reference areas (not including non-native, invasive species such as noxious weeds). A Natural Re cieliCe Area tui each zone should be established in order to measure the success of reclamation. Transects would be established in each zone establish for representative plant communities to enable biologists to determine if desirable species have been successfully established. and it they provide sufficient aerial Cover to adequately protect the sue from erosion and invasive weeds. Reclamation Monitoring will provide evidence of whether a self-sustaining plant community has been established and whether vegetative processes such as reproduction and seedling .stablishinent are occurring. l ranects to late spnng and late summer will provide identification and contribution of most if not all dominant plants found on NPR (Ferchau, 1973). Monitoring results can he compared to studies conducted for oil shale projects in the 19713's. Ferchau, 1973 covers the ExxonMobil property adjacent to much of NPR lands. Environmental studies conducted on NPR by previous owner Union Oil of California should be located and could serve as reference information. Weeds The need to cooperate with adjoining landowners. especially those upstream, to reduce and control invasion of noxious weeds is imperative. Two species. Canada Thistle and Huundstongue are currently Invading undisturbed NPR lands on the East and West Forks of Parachute Creek from adjoining private and public lands. Encana needs the cooperation and assistance fano adjoining Iandovv ners to control this serious problem. A separate integrated vegetation and noxious weed management plan listing and locating all known populations of noxious weeds on NPR is in preparation.

Project: Middle Fork Compressor Sta. Location: Garfield County. Colorado Report: Ron Spillman Date: 2/27/2007 GARFIELD COUNTY, COLORADO: ENVIRONMENTAL SOUND LEVEL SURVEY REPORT General Information Sound levels were measured at four Locations as near as possible to the property lines at the EnCana Middle Fork Compressor Station site. In addition, measurements were made near the two residences closest to the compressor equipment. Map 1 shows the measurement locations. GPS coordinates are given below. The sound survey was conducted to determine if the compressor station is currently in compliance with COGCC noise regulations. The area is designated as "Residential/Agricultural/Rural," and as such is subject to allowable noise limits of 55 dB(A) during the 7am to 7pm period and 50 dB(A) during the 7pm to 7am period. The measured sound levels were under 50 dBA at all locations, and thus showed compliance with the daytime and nighttime limits. The compressor station was completely inaudible at all of the property -line and residential positions. EnCana ran as many compressor units as possible during the sound level testing. Four of seven 1250 hp recip units were running, and two of three 7500 hp electric units were running. Thus 20,000 hp out of a total of 31,250 hp was in operation. Using a conservative adjustment factor of 10 log (31,250/20,000) = 1.9 dB, we would anticipate that the total station noise contribution would have been approximately 2 dB(A) higher if all ten compressors could have been run simultaneously. However, because the compressor station was completely inaudible at all of the property -line and residential measurement locations, it would be unnecessary and inappropriate to add this adjustment to the measured environmental sound level values. Due to contamination from traffic noise in the measurement areas, the durations of the readings ranged from 30 seconds to 5 minutes. All measurements were sufficient to properly characterize the environmental sound conditions while minimizing traffic interference.
