Vaughn PVCMI Land Planning Division, President 1038 County Road 323 Rifle, CO 81650 BUILDING & PLANNING DEPARTMENT RE: Cottonwood Compressor Station to Webster Hill 24 -inch Natural Gas Pipeline Dear Mr. Vaughn, Staff has reviewed the Pipeline ROW Application for the Cottonwood Compressor Station to Webster Hill 24 -inch Natural Gas Pipeline submitted to this office on May 4, 2007. XLLntM ILL WIRIER"\ StA110,4 W 1/! Ste II 1G5 3 24 M]IM1/I CAJKChNCPit t l. *` *inn, .I q tab .V gi f' f - •.0^U,. ,\ Molt• Mss Staff understands this project generally consists of the construction of 8.3 miles of a 24 - inch natural gas gathering pipeline, 2.0 miles of 12 -inch natural gas gathering pipeline and two compressor stations to be constructed by Bargath, Inc to gather natural gas from Williams Production RMT wells in the area. The total disturbed acreage on private land is 109.34 -acres. Approximately 1.38 miles of the pipeline are located on public lands, the remainder is located in private lands comprised of 5 different owners. A large portion of the proposed line is located within already disturbed right-of-way limiting new surface disturbance. The Applicant has obtained signed surface agreements from all of the private properties over which the line is proposed and these signed agreements were included in the submittal. These agreements also contained maps that identified the permanent, construction, and staging area right -of - 108 Eighth Street, Suite 401 • Glenwood Springs, CO 81601 (970) 945-8212 • (970) 285-7972 • Fax: (970) 384-3470 ways. A typical map is shown here that clearly defines where activity is to take place on a particular private property. S aff understands the purpose of this line is to connect the outlets of four existing and wo new field compressor stations to the upstream end of the recently constructed 30 -inch gathering line. Once the gas has been collected and sent via this proposed 24 -inch line to the existing 30 -inch line, it is then conveyed approximately 8 miles west to the existing Williams Production RMT's Parachute Creek Gas plant for processing and delivery to market. The two new compressors (Rabbit Brush and Webster Hill) being proposed are appurtenant to this line and are, by definition, considered in this review as part of the pipeline facility. The two compressor stations are to include two "Caterpillar" type compressor engines in a building (60' x 235') at each site with the expansion for two additional compressor engines at each site for a total of 4 engines ate each site. Noise studies were included that show the compressor stations can comply with state statute noise levels at full build out. m y a: 1roAreoO z W o ;24 SECTION p i v t -1 v L Extra Warkepace `p •O.

This letter shall constitute Garfield County's review of the project. [The photo to the right shows the view looking north towards the main entrance to the Naval 00 Shale Reserve area where this proposed line will cross County Road 246.] Staff referred the Application to the following Agencies / Departments whose comments are included here for review and attached to this letter which is required by Resolution 2005 — 53: A. Burning Mountain Fire Protection District: No comments received. B. City of Rifle Fire Protection District: No comments received. C. Garfield County Road and Bridge Department: The Garfield County Road & Bridge Department has no objection to this application with the following comments: 1) There will be no entrances to any County roads for the project and the only impact to the County road system will be during the construction of the pipeline project; 2) All trucks hauling equipment or materials for the pipeline will abide by the Garfield County Road & Bridge Department oversize/overweight permit system; and 3) A utility permit number GRB07-U-39 was issued on May 4, 2007 for the pipeline crossing for Cr. 246 for a road bore. D. County Vegetation Management: The Vegetation / Rehabilitation Plan is acceptable. This Department recommends a bond for revegetation security in the amount of $272,500 to be held by Garfield County which is equal to $2,500 per disturbed acre for a total of 109 acres. 3 E. County Oil & Gas Liaison: • 15 — Emergency Response Plan — Sec. II 2.a.4 o Several contacts were not included in the Regulatory Notification description. Add the following contacts: • Emergency Control Center — 911 ▪ Colorado, Oil & Gas Conservation Commission — Jaime Adkins (970' 285-90K1 • Garfield County Assist Cowart Manager — Jesse Smith (970) 309-3440 • Garfield County Public Health - Jim Rada — (9 70) 623-5200 ext. 8113 • Garfield Counn' On & Gas Department —.Tuck Jordan — (970) 625-0973 est. 2006 • 1 — Emergency Response Plan — Sec. II 2.b.1 o The emergency plan states that \VPC personnel should be contacted in the event of a tire. The Oil & Gas department would advise that the Emergency_ Control Center (Fire Department & Sheriff Department) should be contacted immediately. A delay u1 notify the Emergency Control Center may result in time lost and increased damage. F. Mountain Cross Engineering: Reviewed the proposal and provided the following comments which are also followed by the Applicant's response: 1) Pipeline crossings within the plan sheets state that crossings should happen at, "...low flow period, if possible". The Nationwide Permit 12 requires that it happen at low flow. The statement, "if possible" should be removed from the details. Applicant Reply: We agree that the Nationwide Permit 12 will guide the work to be done within areas under the U.S. Army Corp of Engineers jurisdiction. The attached ERO letter dated 4/5/07 details the requirements to be met. 2) The pipeline passes beneath an overhead power line between Sta. 107+71 and Sta. 109+72. Issues with equipment and overhead clearance and power line appurtenances are not discussed. The Applicant should coordinate with the power company to verify. Applicant Reply: Please see Tab 22- Construction Management Plan of our application packet. Page 21- "Health and Safety" of the Construction Management Plan notes: "Health and Safety - The following health and safety measures shall be made a requirement of the pipeline construction work: Special precautions shall be taken when working on pipeline segments parallel to, crossing or near high voltage overhead electric power transmission lines. These precautions shall include: 4 Measuring the pipe -to -ground voltages on pipe sections each day at the commencement of work, prior to work involving pipe contact and when directed by a qualified person. Rubber tired vehicles operating on a common pipeline and powerline ROW area shall be strap grounded to mitigate capacitive coupling. Grounding shall be made using a metal chain or conductive strap connected to the vehicle frame and contacting the ground. ➢ Vehicles shall not be refueled on or near an electric powerline ROW. The pipeline contractor shall coordinate with affected utilities to avoid utility disruptions." Full compliance with OSHA regulations are noted within the contract documents. 29 CFR 1926 Subpart K, Electrical, OSHA Standard 1926.550(a)(15) and other sections within the regulations note that a mimimum of 10 feet must be maintained between equipment and energized overhead power lines. 1926.550(a)(15)(i-ii) additionally notes that lines rated over 50kV., minimum clearance between the lines and any part of the crane or load shall be 10 feet plus 0.4 inch for each 1 kV., or twice the length of the line insulator, but never less than 10 feet. Additional safety precautions will include warning signage on both sides of the overhead power line alerting personnel of energized overhead powerlines. 3) Whether or not any of the jurisdictional drainages also have mapped floodplains is not discussed. Garfield County flood plain permits may be required. Applicant Reply: The ERO letter dated 4/5/07 notes that four of the drainages are ephemeral and that Balzac Gulch is intermittent. I spoke with Clint Henke with ERO on 6/8/07 regarding this question of floodplains. Clint and I agree that these drainages have not been mapped by FEMA and I have verified such on the FEMA mapping website. Additionally, the installation of buried utilities within any drainage does not effect the flood elevation, as this is a temporary disturbance of the drainage and this piping is immediately backfilled. This disturbance is regulated through the NWP 12 noted above in question #1. ERO noted that this is consistent with their work in other jurisdictions as well. I have additionally reviewed section 6.00 of the Garfield County Zoning Regulations "Floodplain Regulations" and find that the activity of utility installation, below grade of the bottom of a drainage, does not require a floodplain development permit in Garfield County. 4) Several roads will be inaccessible during construction of the pipeline crossings. It is not discussed what roads will require access to be maintained and means of doing so. Applicant Reply: The roadways to be directly impacted within this project are all roads on private property. Safety barriers will be maintained to ensure the safety of workmen and workmen traveling on private property. County Road #246 will be bored and this traffic will not be impacted. 5 5) A CDOT permit will be required. Applicant Reply: Please find attached a letter to Fred Jarman dated 6/7/07 requesting an amendment to delete the 12" Rulison jumper line that would have required a boring of 1-70 and a Special Use Permit from CDOT. This permit is no longer required. 6) It is not clear whether or not the Bureau of Land Management has the authority to give approvals for construction on the lands of the United States Naval Oil Shale Reserve. Applicant Reply: Naval Oil Shale Reserve -1 -Properties East of Parachute, CO and Naval Oil Shale Reserve -3- Anvil Points Oil Shale and Research Facility was transferred to the U.S. Department of Interior via U.S. Senator Ben Campbell legislation in the late 1990's. It appears that Parcel numbers 2173-222-00-951 and 2175-082-00-953, noted on sheets 3, 4 and 5 of the alignment sheets within Tab 2, are noted as U.S. Naval Oil Shale Reserve but have indeed been transferred to the U.S. Department of Interior. Conversations and negotiations between Williams Production RMT Co. landmen and the U.S. BLM have confirmed the details of this ownership. We have mailed notice to the U.S. Naval Oil Shale Reserve in c/o the U.S. Department of Energy office in Grand Junction simply because the federal agencies have not updated the files of the Garfield County Assessor's office. 7) An agreement with the Bureau of Land Management has not been executed. Applicant Reply: This is correct. The SF 299 was submitted to the U.S. BLM on 3/13/07 and is attached in Tab 7. After the license is approved by the BLM a copy of this will be submitted to Garfield County for their files. 8) To mitigate building movement and settlement, the recommendations of the geotechnical engineer are that the buildings be built on piers. The use planned for the buildings may not allow movement and may be required to be built with pier foundations. Applicant Reply: We will follow the recommendations of Geotechnical Engineering Group in regards to construction of the Rabbit Brush and Webster Hill compressor stations. Each of the buildings has building permit applications under review by the Garfield County Building Department. 9) The application does not discuss whether or not sewer and water facilities will be necessary for any employees. 6 Applicant Reply: The compressor stations will be unmanned facilities with one employee reviewing the facility daily. There will be a portable toilet on- site and water will not be supplied on-site. 10) The traffic impacts discuss construction traffic, which is temporary in nature. The application should discuss the post construction traffic anticipated and the impacts that traffic will have on the surrounding roads. Applicant Reply: The compressor stations will be unmanned facilities with one employee reviewing the facility daily. During maintenance, one additional service truck and employee will be on-site. This would equal 4 average daily trips to each of the compressor stations. All of these trips will access CDOT Highway 6 & 24. 11) In the noise analysis, the decibel levels at the eastern property line have not been detailed. Applicant Reply: Please see Tab 23- Review Criteria. Attached within is the HFP noise model prediction dated 4/30/07 for the Webster Hill Compressor Station. A schematic on page 7 of the report notes that the phase 2 expansion of the station will maintain less than 65 dB(A) 350 feet from the facility. The outline noted within this diagram as "Property Line" is incorrect. This is the lease line of the facility. The distance between the lease line and the W.F. Clough property line is actually in excess of 1,000 feet in all directions. Also attached within is the HFP noise model prediction dated 4/30/07 for the Rabbit Brush Compressor Station. A schematic on page 7 of the report notes that the phase 2 expansion of the station will maintain less than 65 dB(A) 350 feet from the facility. The outline noted within this diagram as "Property Line" is incorrect. This is the lease line of the facility. The distance between the lease line and the ExxonMobil property line is actually in excess of 500 feet in all directions.
