HomeMy WebLinkAbout4.0 Staff reportGarfield County To: Board of County Commissioners From: Gale Carmoney, Building and Planning Department Date: December 30, 2010 RE: Pipeline Development Plan Review for Hunter Mesa to Pumba Pipeline — a 20 -inch natural gas pipeline and up to a 10 -inch water line — PDPA - 6591 I. Project Overview The proposed pipeline is located in the Sections 2, 3, 10 and 12 of Township 7 South, Range 93 West and Section 35 of Township 6 South, Range 93 West, Garfield County, Colorado. Encana Oil and Gas (USA) Inc. (Encana) is proposing the installation of two new pipelines; a 20 -inch diameter gas pipeline and a 10 -inch diameter water line. Both will be constructed of high pressure steel of similar pressure capabilities and buried a minimum of 48 inches below graded surface. When the water line are no longer needed to transport water to gas drilling operations this line can be converted to a gas transmission line. Typical above -ground appurtenances; block valves, meters, pig launchers and receivers will be installed at both ends of the pipeline. Over the next two to three years, drilling activity is expected to increase in this area and 3rd party companies want to take advantage of EnCana's existing infrastructure to deliver their product into the pipeline system. Current infrastructure is not capable transporting future anticipated volumes; thus the need for additional infrastructure. Eventually, two more natural gas -driven compressor units (3616 and 3612) will be installed at the existing Hunter Mesa Compressor Station (HMCS) to supplement pressure required to move the additional gas supply. The building over the existing compressors will extend to enclose the new units and a county building permit will be obtained prior to construction of the building extension. The path of this pipeline development project will begin at EnCana's HMCS located in the Southeast corner of Section 1, Township 7 South, Range 93 West, and cross 4 separate property holdings; NE by NE LLC, Shaeffer, Benzel and Bureau of Land Management (BLM). Termination of the pipeline is near the Pumba Compressor Station located on BLM land in north Y2 of the northeast '/4 of Section 10, Township 7 South, Range 93 West. Total length of the project will be approximately 21,054 feet (-3.9 miles); 8,460 feet on BLM surface lands and 12,712 feet on fee surface lands. 1 The new pipelines will be located within an existing right-of-way (ROW) that varies in width from 30 to 75 feet depending on the agreements with the various property owners. As proposed, the temporary construction ROW will be approximately 65 feet in width and total disturb area will be approximately 31.4 acres. The majority of the ROW will occur within an existing, previously disturbed pipeline corridor. Where new pipelines parallel EnCana's existing gas lines and waterlines, no new disturbance will occur outside the previously disturbed areas. The proposed natural gas pipeline will be offset 15 feet from edge of existing pipelines. None of the existing. infrastructure will be removed or replaced. Surface Use/Right-of-Way (SUAJROW) Agreements have been provided by all property owners. Access to the pipeline will be by existing roads and SUAIROW easements. No new access points will be constructed on Garfield County Roads. County Road 319 (Mamm Creek Road) will be bored. k27NW'_ nusIER 1611/114 I.34NI1 .1 S xi_ N......4iff6H K25 i L2' !]27NW 1336) 1336 RO26EM911 JJ!FNW 34NW Mi•g•E0 35NW - 30 NW 9 RJIA [-F4219 2 w. 1431 TOS P T8 J 9EN7lI 11 fj-PUNren MESA C-AEEAA WATER r1 -- TREATMENT FACILITY NIU ' Nl 1.1 A 10.6' OLM 12 C7r QllW F12 F Il 6NAEfrR RIaJAK t 2 -a If7 C15 1,10 HMV( CM LEGEND - . rRoro,ro oAs PIPIIONR ACROSS FE0 LANDS (12_712 rn E7) . — .. .

Ltd. (Katherine F. Rogers) Parcel # 2401-071-00-127 There are five buildings within 350 feet of the proposed pipelines. These buildings include a residence, garage and building on parcel # 2177-353-00-487 and an outbuilding and pump house on parcel ## 2403-024-00-071. III. Notice to Surface Owners The proposed pipeline is situated on property owned by property owners identified above and evidence of surface owner notification and surface agreements has been provided. IV. Need for Proposed Action Drilling activities are expected to increase in the Mamm Creek field over the next two to three years and third party companies want to take advantage of Encana's existing infrastructure and deliver gas into their system. Presently, Encana's 12 -inch high pressure discharge pipeline and 4 existing compressors units cannot move the projected volumes. With the introduction of the 20 -inch gas pipeline and 10 -inch water line will enable Encana to deliver more natural gas to market. V. Regulatory Permit Requirements The following table provides the applicable permit agency name, permit required, and status of permit for this application. All necessary permits have been obtained for this application. Permit Agency Permit Needed Permit Status Colorado Department of Public Health and Environment - Water Quality Control Division Colorado Discharge Permit System The CDPS Permit was issued on 710112007.

Project Facilities '1'hc proposed gas pipeline will require above ground appurtenances (block valve, meters, pig launchers and receivers) at both ends of the pipeline. Additional above ground appurtenances will be required to connect existing gathering lines to the new 20 -inch gas pipeline. After completion of the reclamation activities, above ground pipeline markers will be installed over the center line of each pipeline. 4 VIII. Construction Schedule Construction of the pipeline is scheduled to begin upon receipt of application permits and will take approximately eight to 10 weeks to complete. Working hours will normally range from sunrise to sunset Monday through Saturday. Due to stipulations in the BLM right-of-way grant, pipeline construction activities on BLM land are tentatively scheduled for May 2011 and could continue into July 2011. No construction may Occur on BLM land from December 1 to April 30 to avoid disturbance of big game winter range. IX. Sensitive Area Survey Several reports are provided to address areas of concern within and adjacent to the proposed pipeline including a Biological Resources and Sensitive Areas Report and Class 1 and 111 Cultural, and Paleontological Resource Inventory, The Biological Resources and Sensitive Areas Report prepared by WestWater (dated August 2010) indicates that there are no Threatened and Endangered plant species (TESS) or habitats were found during the survey and therefore no affects on TESS plants are expected. Two federally endangered fish species are known to occur in the Colorado River. This report states that 'It is unlikely that endangered fish in the Colorado River would be affected by this project since sediments are mostly contained by topography and not likely to reach the river. Best Management Practices (BMPs) and Spill Prevention Counter Control (SPCC) measures should be followed to reduce any potential impacts to aquatic environments." The West Water Report indicated that there is the potential for five state listed threatened, endangered, or special concern species to occur within the project area, however, none were observed during the survey. Although the West Water Report concluded there should be no significant impacts to a number of animal species analyzed in this study, there are recommendations for some protective measures; in particular, planning for sensitive time periods and areas for elk, mule deer, migratory birds and raptors. Among the recommendations was consultation with the Department of Wildlife (DOW) concerning elk and deer habitat and a survey to determine if new raptor species nests are in the project area to avoid interference with breeding, nesting and brood activities. These rnitigation recommendations are conditions of approval. The Class 1 and Class III Cultural Resource Inventory by (Grand River Institute (dated September 9, 2010) indicates that one prehistoric site was recorded but was determined that it was not eligible for listing on the National Register of Historic Places. Also, no paleontological localities have been recorded in or near the area, therefore, a determination of "no effect" is deemed appropriate for the proposed pipeline and no further work is recommended. A letter dated August 31, 2010 prepared by Olsson Associates inventoried the drainage crossings for the proposed pipeline upgrade. This letter indicates that the pipeline route extends across the US Army Coips of Engineers (USACE) jurisdictional water of Manun Creek and 11 non jurisdictional drainages. This information has been submitted to the USACE as a courtesy notification. Since utility activities will cross jurisdictional wetlands, a Nationwide 404 Permit 412 has been provided by the USACE. 5 X. Revegetation Plan The Stormwater Management and Weed Management Plans provide adequate reclamation methods and seed mixes to reclaim the disturbed areas of the pipeline corridor. A revegetation bond has been provided in the application for the amount of $47,825 for 18.97 acres as specified by the County Vegetation Manager. XI. Wccd Management Plan The Hunter Mesa to Pumba Pipeline project's Integrated Vegetation and Noxious Weed Management Plan prepared by West Water Engineering dated August 2010 has been provided with this application and approved by the County's Vegetation Manager. Comments from the Vegetation Manager are included in the referral section of this report and the manager's requests are conditions of approval. XII. Emergency Response Plan An Emergency Response Plan included with this application has been reviewed by the Rifle Fire District. Requests from the district are included as conditions of approval. XIII.Traffic Impact County Road 319 (West Manun Creek Road) and private roads will provide access to the project. Construction traffic will consist of approximately 8 pickup trucks, 2 crew trucks, and 2 semi -haul trucks to get the equipment on location. A fuel truck may periodically be on site to deliver fuel for equipment. The majority of these trucks will he making a single round trip per day to the project area. It is estimated that the semi -trucks will make three round trips depending on equipment and pipe needs. Impacts will be temporary and cease when construction of the pipeline is complete. Working hours normally will range from sunrise to sunset Monday through Saturday. Garfield County Road & Bridge Dept. has reviewed the project and requested that EnCana submit a Utility Permit approximately 30 days prior to construction. XIV. Staging Areas The construction staging areas will be within the temporary construction right-of-way and on well pads MOB, .12W and the HMCS site indicated as 'Temporary Use Areas (TUA) on the Plan and Profile. Encana's contractors will haul the pipe used for this project from a wholesale distributor located in Garfield County. XV. Hydro Test Water The natural gas pipeline will be hydrostatically tested. The hydro test will require approximately 320,000 gallons of water. The water for the test will come from water rights that Encana holds on the Colorado River. Those water rights have been verified by the applicant's legal consul. After the completion of the hydro test, the water will be discharged into either the Renzel or Hunter Water Treatment Facility. XVI. Referral Comments Staff referred the application to the following State agencies and/or County Departments for their review and comment. Comments received are briefly mentioned below or are more 6 comprehensively incorporated within the appropriate section of this report. Comments from the referral agencies and departments are attached as Exhibits. A. County Road and Bridge Department: This department has commented on this application and requests that the applicant apply for a utility permit 30 days prior to construction of project. B. County Vegetation Management: This department's comments are as follows: Noxious Weeds The applicant has provided a noxious weed survey and management plan and are acceptable to staff. Staff requests that the applicant cut and treat the tamarisk indicated on the west side of the compressor station and that they inform the Vegetation Management Department when this has been completed. Revegetation 'fhc reclamation plan is acceptable. The applicant has quantified the level of disturbance on private lands as 18.97 acres. The revegetation security rate is $2,500 per acre. The total revegetation security is $47,425. The applicant has provided a copy of the revegetation security. Staff does request that the applicant make the seed tags available to Garfield County upon completion of the reseeding efforts. As always staff is concerned about yellow sweet clover (Melilotus offcinalis) ending up in seed mixes used for pipeline revegetation. We request that EnCana closely monitor reseeding contractors to insure that yellow sweet clover is not used in revegetation efforts. The security shall be held by Garfield County until vegetation has been successfully reestablished according to the Reclamation Standards in the Garfield County Weed Management Plan. It is the responsibility of the applicant to contact the County, upon successful revegetation establishment, to request an inspection for security release consideration. 'l'he Reclamation Standards at the date of permit issuance are cited in Sections) 4.06, 4.07 and 4.08 of the Garfield County Weed Management Plan (Resolution 42002-94). Erosion Control Any straw or hay bales used in erosion control shall be certified weed free. C. Garfield County Development Engineer (Mountain Cross Engineering, Chris llale): "The Applicant proposes to use Title 49, CFR part 192 for the pipeline construction specifications but the pipeline manufacturer's specifications may be more stringent and the construction shall conform to the more stringent requirements. 7 Since the construction is likely to take place in 2011, the arca will need to be resurveyed by qualified biologists for raptors. The result of the survey should be provided to Garfield County." D. City of Rifle: "EnCana will fully comply with the City of Rifle Watershed Ordinance as it relates to the pipeline construction proposed within portions of Sections 2, 3, 10 and 12 of Township 7 South, Range 93 West and Section 35 of Township 6 South, Range 93 West." E. County Oil and Gas Liaison: This department indicated that they have no comments at this time. F. Fire Protection Districts: (1'lie Rifle Fire District) has reviewed the submittal for the construction of one 24 "gas line and one 12" water pipeline that would run for approximately 3.9. miles from Hunter Mesa to Pumba. The following are my comments: 1. All comments from the fire district review recently conducted on the PDPA 6578- East Dry hollow pipeline Loop- phase 1 addition apply where applicable (attached). Note: All issues have been adequately addressed and future submittals by EnCana should reflect these. Documents needed for this project are: a. Maps- Since this is a specific project, location of assembly points, emergency response staging areas, water supplies and normal routes of fire department vehicle access should be preplanned along the 3.9 mile route as much as possible, b. Narrative -Section 4.7- Explosives- if explosives are used a blasting permit maybe required from Rifle Fire. More information is needed. c. Narrative -Section 4.7- Hazardous Materials- if any hazardous materials are used that are not regulated by COGCC then a review by Rifle Fire may be needed. More information is needed 2. Pipeline development plan: a. #16- emergency phone number for Rifle Police is wrong. Rifle Fire's nunnber is good. 3. Since this project will require an addition to the existing compressor station the following comments may apply - I listorically, Rifle Fire Protection District has not done a detailed review on compressor stations in our district. Federal, State, County, COGCC and industry rules & standards have been relied upon. We believe this has been appropriate and reasonable. We can assist in the following areas, if appropriate, by applying the International Fire Code: a. Water supply requirements for fire protection h. Fire apparatus access including turn -a rounds c. Plan review and installation inspections & testing for flammable gas sensors. EMD's, fire eyes, auto — ventilation, auto -shutdowns and the like. If these areas are already handled by another Authority Having Jurisdiction then no further action is needed 4. Narrative- page 10, section 2.10 change Rifle Fire's emergency contact number Burning Mountain Fire: This agency concurs with the Rifle Fire Protection District's comments. 8 G. Surface owners: No commcnts were received from property owners that have Surface Use Agreements with EnCana. There is, however, a property owner within 200 feet of the pipeline project (Keith Goddard) who has expressed a concern for his water well which is approximately 60 feet from the proposed pipclinc aligrunent. A letter dated October 18, 2010 from Mr. Goddard is attached as Exhibit I. Summary of Review The proposed pipeline project is located in the Sections 2, 3, 10 and 12 of Township 7 South, Range 93 West and Section 35 of Township 6 South, Range 93 West, Garfield County, Colorado. The applicant, EnCana Oil and Gas (USA) Inc. is proposing the installation of two new pipelines; a 20 - inch diameter gas pipeline, and a 10 -inch diameter water line. The length of the pipeline is approximately 21,054 feet (3.9 miles) in length and will be located within an existing pipeline right- of-way that varies from property owner to property owner; 8,460 feet of that line will be on BLM land. Both gas and water lines will be constructed of high pressure steel to similar pressure capabilities and buried a minimum of 48 inches below graded surface. This pipeline project will also require the typical above -ground appurtenances (block valves, meters, pig launchers and receivers) at both ends of the pipeline and eventually the addition of new compressors at the Ilunter Mesa Compressor Station, '1'hc proposed 20 -inch gas line will provide additional transportation capacity for EnCana's area wide system and the 10 inch water line can easily be converted to a gas transmission line at a later date when it is no longer needed for water transport. The gas pipeline will maintain a 15 feet off set from any existing pipelines. The construction right-of-way width will be 65 feet and construction of the proposed pipelines will disturb approximately 31.4 acres. Ilowever, no new disturbance will occur outside the existing previously disturbed area. Both pipelines will begin at Encana's Hunter Mesa Compressor Station (SE corner of Section 1, T7S, R93W) and end near the Pumba Compressor Station (N %z of NE ° of Section 10, T7S, R 93 West). Upon substantive review of the documents submitted against the required standards and criteria in Section IX of the Unified Land Use Code Resolution 2008, as amended, Staff recommends the Building and Planning Director approve EnCana's Hunter Mesa to Pumba pipeline (PDPA 6591) with conditions. The final date for the Director's Determination of Approval with Conditions is December 30, 2010. This approval will be sent to the Board of County Commissioners (BOCC) to determine if they wish to call up the matter. Unless it is not practical from a scheduling perspective, the BOCC has 14 calendar days to determine if they need to call up the application. Fourteen days from the date of the Directors Determination will be January 13, 2011. No Land Use Change Permit can be issued until all conditions of approval have been met. The specific conditions include the following: 9 1. Any equipment used in construction or operation of a pipeline shall comply with the Colorado Oil and Gas Conservation Commission Rules and Regulations, Section 802, Noise Abatement. Additionally, all power sources used in pipeline operations shall have electric motors or muffled internal combustion engines. 2. Pipeline operations shall be located in a manner to minimize their visual impact and disturbance of the land surface. Facilities shall be painted in a uniform, non -contrasting, non -reflective color, to blend with the adjacent landscape.

It was my understanding from previous emails that this activity was previously permitted by Encana, and all they need to do is contact City staff and notify them of this pipeline addition. Therefore, I think we would only ask Garfield County to include a condition that states, "Encana will fully comply with the City of Rifle Watershed Ordinance as it relates to the pipeline construction proposed within portions of Sections 2, 3, 10 and 12 of Township 7 South, Range 93 West and Section 35 of Township 6 South, Range 93 West."

The following are my comments: 1. All comments from the fire district review recently conducted on the PDPA 6578- East Dry hollow pipeline Loop - phase 1 addition apply where applicable ( attached). Note: All issues have been adequately addressed and future submittals by EnCana should reflect these. Documents needed for this project are: a. Maps- Since this is a specific project, location of assembly points, emergency response staging areas, water supplies and normal routes of fire department vehicle access should be preplanned along the 3.9 mile route as much as possible. b. Narrative -Section 4.7- Explosives- if explosives are used a blasting permit maybe required from Rifle Fire. More information is needed. c. Narrative -Section 4.7- Hazardous Materials- if any hazardous materials are used that are not regulated by COGCC then a review by Rifle Fire may be needed. More information is needed 2. Pipeline development plan: a. #16- emergency phone number for Rifle Police is wrong. Rifle Fire's number is good. 3. Since this project will require an addition to the existing compressor station the following comments may apply - Historically, Rifle Fire Protection District has not done a detailed review on compressor stations in our district. Federal, State, County, COGCC and industry rules & standards have been relied upon. We believe this has been appropriate and reasonable. We can assist in the following areas, if appropriate, by applying the International Fire Code: a. Water supply requirements for fire protection b. Fire apparatus access including turn -a rounds c. Plan review and installation inspections & testing for flammable gas sensors. EMD's, fire eyes, auto — ventilation, auto -shutdowns and the like. If these areas are already handled by another Authority Having Jurisdiction then no further action is needed 4.

Harris'; Chris Bornholdt (cbornholdt@gareosheriff.com) Subject: PDPA-6578- East Dry Hollow pipelinieLoop- Phase 1 addition Molly, I have reviewed the Emergency Response Plan for the East Dry Hollow pipeline loop -file Name PDPA-6578. The applicant is Encana Oil and Gas and the summary is the construction of one gas pipeline up to 24 " in diameter and one water pipeline up to 16 " in diameter for approximately 3.29. miles. The following are my comments: 1. Emergency Response Plan: a. Activation and notification section does not contain when to call 911. This should be the first step in any emergency and for all of Encana's emergency classifications/levels. b. IC should reflect a unified command structure with local emergency responders. c. Since this is a specific project, location of assembly points, emergency response staging areas, water supplies and normal routes of fire department vehicle access should be preplanned along the 3.29 mile route as much as possible. 2. South Piceance- Emergency Notification Chart a. This has Fire /EMS as "third party support". This appears to conflict with federal & state law and needs to be clarified. b. As indicated above the structure should be at best a unified command. 3. Spill Plan: a. Section 4.2 recommend deleting last line that states "EnCana's employees and contractors are not to contact regulators unless directed to do so by their manager". This could be construed to also include 911 response which would be inappropriate. b. Table 1- should have Garfield County agencies listed and not Rio Blanco agencies. c. Section 5.3 — under both Encana paragraphs change Rio Blanco county references to Garfield County. d. Section 7.1- the decision matrix for spill clean-up is not included. Resubmittal is required e. Section 7.2- it appears that the last sentence should read 3.1 instead of 2.1 4. EDHLI_add narrative dated 9/2010 a. Section 2.10 change out Parachute contacts to Rifle/Silt contacts b. Section 4.7- Explosives- if explosives are used a blasting permit maybe required from Rifle Fire. More information is needed. c. Section 4.7- Hazardous Materials- if nay hazardous materials are used that are not regulated by COGCC then a review by Rifle Fire may be needed. More information is needed 5. Master Stormwater Management Plan- Mamm Creek Unit- COR -034840 dated June 2009. a. Section 3.2.2- add fire district for immediate notification of any spills. Section 2703.3 of the 2003 International Fire Code defines this (with exceptions) as well as section 2703.3.1 defines reporting of unauthorized spills. More information is needed. b. Section 3.3 refers to Appendix E- Stormwater Manual of Best Management Practices (BMP's). The cover sheet is the only thing present in this submittal. if a review by the fire district is appropriate then a re submittal is required. As submitted, the Rifle Fire Protection District does not accept the above documents. Furthermore the District recognizes that Burning Mountain Fire Protection District has shared response and review responsibilities. More information and clarification is needed. The Rifle Fire Protection District does not believe that construction or approval of this project should be delayed. A suggestion for resolution is that a meeting be scheduled as part of the approval to adequately address the above issues with all parties References: 2003 international Fire Code file://C:\Documents and Settings\gcarmoney\Local Settingsl'I'emporary Internet Filcs\Co... 12/28/2010 Page 2 of 2 "The Mission of the Rifle Fire Protection District is to Enhance Health and Safety and to Protect the Life , Home and Property of the People We Serve" Kevin C.

Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds develop, cut and bag seed heads. 2. Cut roots with a spade just below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering, but can reduce total seed production. (Sirota 2004) Table 4. 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. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended after August 15 when natural precipitation is present). In the fall, plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3. Mowing usually is not recommended because the plants will flower anyway; seed production should be reduced. Many studies have shown that mowing perennials and spraying the re -growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its basic biology. Timing of application must be done when biologically appropriate, which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only 1/2 in. —1 in. long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. (Simla 2004) Some weeds, particularly annuals and biennials, can develop resistance to herbicides. The ability to quickly develop immunity to herbicides, especially when they are used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration according to the product label. Most misuse is centered on excessive application, either in frequency or concentration. This results in mostly top kill and resistant phenotypes. 3.7 Best Management Practices — Noxious Weeds Construction: The following practices should be adopted for any construction project to reduce the costs of noxious weed control and aid in prevention efforts. The practices include: ■ Top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; WestWater Engineering Page 7 of 11 August 2010 • Wetland vegetation, if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub -soil relative to the position from which the wetland sod was removed; • Cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • In all cases, temporary disturbance should be kept to an absolute minimum; • Equipment and materials handling should be done on established sites to reduce area and extent of soil compaction; • Disturbances should be immediately reseeded with the recommended mix in the re - vegetation section; • Topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses, if stored longer than one growing season; • Prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • If working in sites with weed -seed contaminated soil, equipment should be cleaned of potentially seed -bearing soils and vegetative debris prior to moving to uncontaminated terrain. In areas with slope greater than three percent, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When utilizing hydro -seeding followed by mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. Herbicides: Annual and biennial weeds are best controlled at the pre -bud stage after germination or in the spring of the second year. The species identified in the survey are susceptible to commercially available herbicides. Selective herbicides are recommended to minimize damage to desirable grass species. Professionals or landowners using herbicides must use the concentration specified on the label of the container in hand. Herbicides generally do not work better at higher concentrations. Most herbicide failures observed by WWE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient translocation process. Most herbicide applications should use a surfactant, if directed on the herbicide label, or other adjuvant as called for on the herbicide label. Grazing: In the event grazing is allowed in the project arca, it should be deferred in reclaimed areas until the desired plant species that have been seeded are established. Alternative Methods: An alternative method, particularly where there is poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi, typically referred to as AMF. These fungi, mostly of the genus Glomus, are symbiotic with about 80 percent of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful when reclaiming this project. In symbiosis, the fungi increase water and nutrient transfer WestWater Engineering Page 8 of 11 August 2010 capacity of the host root system by as much as several orders of magnitude (Barrow and McCaslin 1995). Over-the-counter commercial products, which are better adapted to coating seeds when re- seeding and treating roots of live seedling trees and shrubs at time of planting, come in powder forth and are available from many different sources. Some also come in granular form to be spread with seed from a broadcast spreader. The best AMP products should contain more than one fungi species. All Colorado State Forest Salida District tree and shrub plantings include the application of AMF. According to District Forester Crystal Tischler, "AMF is worth it" (Tischler 2006). Most, if not all, Colorado Department of Transportation re-vegetation/reseeding projects now require use of AMF and HioSol, a certified by-product of the penicillin manufacturing process composed primarily of mycelium. Compacted soils respond well to fossilized titanic substances and by- products called humates. These humates, including humic and fulvic acids and humin were formed from pre -historic plant and animal deposits and work especially well on compacted soils when applied as directed. 3.8 Commercial Applicator Recommendations A certified commercial applicator is a good choice for herbicide control efforts. Restricted herbicides require a Colorado licensed applicator. An applicator has the frill range of knowledge, skills, equipment, and experience desired when dealing with tough noxious weeds. Reclamation farming services using multiple seed bin range drills and specialized related equipment is available and should be used for reclamation seeding projects. Monitoring: Areas where noxious weed infestations are identified and treated should be inspected over time to ensure that control methods arc working to reduce and suppress the identified infestation. The sites should be monitored until the infestations are eliminated or reduced to acceptable levels. These inspections can then be used to prioritize f=uture weed control efforts. 4.0 .REYECETATICN — RECI.ANMA'I'ION Site specific reclamation plans should be developed with a qualified reclamation contractor. Successful reclamation of the project area is dependent upon soil type and texture, slope gradient and aspect, proper weed control, available water, and rcvcgetation with suitable plant species. Appendix C is a table that provides the recommended seed mix for Pinyon -Juniper Woodland and/or Mountain/Wyoming Big Sagebrush Shrubland. WestWater Engineering Page 9 of 11 August 2010 EXHIBIT 5.1.1.3 Black Bear and Mountain Lion Due to low population densities and large home ranges of both black bear and mountain lion, and because of the extensive amount of available habitat for these species, no significant effects from this project for these species are expected. 5.1.1.4 Small Mammals The amount of available habitat for small mammals, including bats, should not be affected significantly by the proposed project. The amount of disturbance is not expected to affect small mammal populations. 5.1.1.5 Reptiles The amount of available habitat for reptiles should not be impacted significantly by the proposed project. The amount of disturbance is not expected to affect reptile populations. 5.1.2 Aquatic Species 5.1.2.1 Amphibians Downstream individuals would be most susceptible in the event contaminants were introduced to surface water during pipeline construction. The amount of available habitat for amphibians would not be affected by the project. The amount of disturbance is not expected to affect amphibian populations. 5.1.2.2 Endangered Fish The Colorado pikeminnow and the razorback sucker are both federally -listed fish species that occur in the Colorado River. Potential impacts from the project include sedimentation of tributaries to the Colorado River, and spills of chemicals, fuels from equipment, or other hazardous materials. It is unlikely that endangered fish in the Colorado River would be affected by this project since sediments are mostly contained by topography and not likely to reach the river. Best Management Practices (BMPs) and Spill Prevention Counter Control (SPCC) measures should be followed to reduce any potential impacts to aquatic environments. 6.0 EFFECTS TO TESS PLANT SPECIES No TESS plants or their habitats were found during surveys, and therefore no affects on TESS plants are expected. 7.0 MITIGATION RECOMMENDATIONS The following recommendations for mitigation are presented for maintenance and improvement of wildlife habitat, quality, and prevention of human -caused impacts to resources. 7.1 Maintenance and Restoration of Habitat Reclamation plans should include efforts to restore the native vegetation communities once construction is complete in the project area. The companion report to this document, the "integrated Vegetation and Noxious Weed Management Plan (IVNWMP), Hunter Mesa to Pumba Pipeline" (W WE 2010) contains a recommended seed mixture for WestWater Engineering Page 12 of 19 August 2010 reclamation of the disturbed areas. If properly applied, this seed mixture will benefit all wildlife populations in the area. The IVNWMP also recommends ongoing control of noxious weeds which will aid the establishment of desired vegetation in the reclaimed area. 7.2 Planning for Sensitive Time Periods and Areas 7.2.1 Mule Deer and Elk Because the proposed project lies within a sensitive area for wintering big game (as defined by the 2009 COGCC rules), consultation with CDOW is recommended before project development. Disturbances associated with construction activities will likely cause elk and mule deer to select habitats in more secluded areas away from construction. This disturbance should not result in any long-term impacts to mule deer or elk. 7.2.2 Migratory Birds In order to comply with the Migratory Bird Treaty Act by showing a good faith effort to reduce potential impacts on nesting birds, any brushltree clearing at the project site should take place outside of the nesting season. Nesting season for migratory birds is generally considered to occur between May 15 and July 31 in this area for most species. June 1 to July 15 is the peak period when most incubation and brood rearing takes place. If brush/tree clearing can occur prior to May 1, most affected birds will relocate to alternate nesting sites. After mid-to-late July, most fledging has occurred and brush/tree clearing impacts would be minimized. 7.2.3 Raptors Pipeline construction activities within the project area are unlikely to affect raptor populations. if construction is delayed until 2011 or later, the area should be resurveyed to ensure no new raptor nests have been built that may be affected by the project. If nests are then discovered, the potential for possible effects to raptors could be reduced by scheduling construction activities so there is no interference with breeding, nesting, and brood rearing activities of the species occupying the new nest sites. if new nests are discovered during subsequent surveys, WWE recommends temporal and spatial restriction guidelines for construction activities near active nests based on BLM stipulations (BLM 1987), Colorado Division of Wildlife (CDOW) recommendations (Craig 2002 and Klute 2008) and literature review of nesting season timing for raptors in the Roan Plateau region (Andrews and Righter 1992, Kingery 1998). These recommendations are summarized in Table 8. Table 8. Timing and buffer recommendations for active raptor nests.

Disturbed soils within the project area are susceptible to erosion, and downstream water quality could be negatively affected by increased soil erosion. In addition to stormwater management around the project site, other current factors (noxious weeds, livestock grazing, other natural gas development) affecting soil erosion should he managed and remedial measures implemented.

Dear Mr. Carmoney: OCI 1.8 ?010 6Ar= i'i .z COUNTY E 1) 0lNra & PLM VG We are the owners of "Lot B" Cedar Springs Ranch, also known as 1075 North Cedar Springs Ranch Road, Rifle, Colorado. This letter is in response to a notification we received from EnCana Oil & Gas (USA) Inc., regarding the above referenced Pipeline Project. We are very concerned about the location of the proposed pipeline with regard to our property line. We received a Pipeline Vicinity Map showing the location of the proposed pipeline. One of the "buildings" located on our property, as shown on the map submitted to your office by EnCana, is our pump house for our domestic water well. Our well head is located next to our pump house. Our domestic water well, pump house, water line, telephone line, and power poles are all located within our "utility easement". The proposed pipeline location according to EnCana's vicinity map is within a couple feet of our "utility easement". The proposed pipeline location runs the entire length of our "utility easement" next to our fence. We have enclosed a copy of the documents sent to us from EnCana and the plat of our property showing our domestic water well location and utility easement. Our domestic water well sits at a very low geographical point as compared to the route of the proposed pipeline. If there is a leak/break we believe the contents of the pipes would flow downhill. Our concern is possible contamination of our domestic water well. The proposed pipeline will be carrying natural gas and EnCana is also proposing a water line in the same pipeline ditch. (It is not clear if this "water" will be fresh water or "contaminated" water). We are very concerned over possible soil contamination and/or aquifer contamination if either of these proposed lines form a leak or a break in the line. We are also concerned if in the future we need to drill a new domestic water well. It is our understanding from the current Water Well Construction rules that "a well shall not be located closer than 100 feet horizontally to the nearest source of contaminants or 50 feet from a septic tank, sewer line or other vessel containing contaminants". Is the pipeline/waterline considered "other vessel containing contaminants"? Will the pipeline prevent us from drilling a new water Well in the future if needed? We would request the proposed pipeline be located a safe distance to, the east of our property line and domestic water well to prevent contamination if a break or leak occurs in the pipeline. Please consider our comments when reviewing the application for the Hunter Mesa and Rumba Pipeline Project.
