Topography and Slope. Topography and slope determination. Staff Response: The site is virtually flat with elevations ranging from 5,800 to S,840 across the property. The area of disturbance ranges in elevation from 5,820 to 5,833. 5. Natural Features. Significant natural features on-site and aff-site. Staff Response: Hunter Mesa is a significant natural feature in the area bound by Mamm Creek on the east and Dry Creek to the west. This mesa consists of glacial outwash, braided stream flow and wind-deposited alluvium. Vegetation consists of sage, introduced grassland and bare soil. Wildlife includes elk and mule deer habitat including winter concentration area and severe winter range, otherwise the site presents little suitable habitat for most other species. 6. Drainage Features. Existing drainages and impoundments, natural and manmade. Staff Response: The site is located between two existing unnamed tributaries that drain northeast to Mamm Creek. 4 Hunter Mesa Compressor Station BOCC 1/17/11 KE 7. Water. Historic irrigation, tailwater issues, water demands, adequate water supply plan pursuant to Section 7-104. Staff Response: Potable water will not be provided to the un-manned site, however the site will produce water in the process of gas compression. The dehydrator units will evaporate some of the fluid and the remainder will be removed from the site in accordance with federal and state regulations. 8. Floodplain. Flood plain and flood fringe delineations. Staff Response: No applicable. 9. Soils. Soils determination, percolation constraints, as applicable. Staff Response: The Natural Resource Conservation Service {NRCS) maps indicate that construction of the compressor station would occur on Potts loam soil which is comprised of alluvium from basalt and/or sandstone and shale. These soils have low erosion potential and are moderately expansive. 10. Hazards. Geologic hazards on-site, and adjacent to site. Staff Response: There are no identified geologic hazards on or adjacent to the site. 11. Natural Habitat. Existing flora and fauna habitat, wetlands, migration routes. Staff Comments: The site consists of elk and mule deer habitat, vegetation is primarily sage and grasses. No wetlands have been identified in the project area. 12. Resource Areas. Protected or Registered Archaeological, cultural, palentological and historic resource areas. Staff Comments: The Colorado Historical Society conducted a search of Inventory and Cultural Resources within Section 30, Township 6 South, Range 92 West and no sites or surveys have been identified. Section 4-502(E) Impact Analysis. The Impact Analysis shall provide a description of the impacts that the proposed land use change may cause, based upon the standards that the proposed use must satisfy. The Impact Analysis shall include a complete description of how the Applicant will ensure that impacts will be mitigated and standards will be satisfied. The following information shall be included in the Impact Analysis. 1. Adjacent Property. An address Jist of real property adjacent to the subject property, and the mailing address for each of the property owners. Staff Comments: The application contained a list of adjacent property owners and mailing addresses. 5 Hunter Mesa Compressor Station BOCC 1/17/11 KE 2. Adjacent Land Use. Existing use of adjacent property and neighboring properties within 1500' radius. Staff Comments: Uses within 1,500' include oil & gas related activities including compressor stations, pipelines and a well pad. 3. Site Features. A description of site features such as streams, areas subject to flooding, lakes, high ground water areas, topography, vegetative cover, climatology, and other features that may aid in the evaluation of the proposed development. Staff Comments: Two unnamed drainages exist in the vicinity of the project area, topography is fairly level and vegetation consists of sage and grassland. There are no site features that would preclude the proposed use and the proposed use would not significantly impact the existing natural features on the site. 4. Soil Characteristics. A description of soil characteristics of the site which have a significant influence on the proposed use of the land. Staff Comments: The soils in the area would not significantly influence construction or operation of the proposed use. 5. Geology and Hazard. A description of the geologic characteristics of the area including any potential natural or man-made hazards, and a determination of what effect such factors would have on the proposed use of the land. Staff Comments: There are no significant geologic hazards other than moderately expansive soils which would not impact construction or operation of the proposed use. 6. Effect on Existing Water Supply and Adequacy of Supply. Evaluation of the effect of the proposed land use on the capacity of the source of water supply to meet existing and future domestic and agricultural requirements and meeting the adequate water supply requirements of Section 7-104. Staff Comments: Potable water will not be provided at this site. Dehydrator units will evaporate some of the water produced in the compression process, excess water will trucked from the site for ultimate disposal in accordance with Federal, State and local regulations. 7. Effect on Groundwater and Aquifer Recharge Areas. Evaluation of the relationship of the subject parcel to floodplains, the nature of soils and subsoils and their ability to adequately support waste disposal, the slope of the land, the effect of sewage effluents, and the pollution of surface runoff, stream flow and groundwater. Staff Comments: A Drainage Plan, Stormwater Management Plan and Spill Prevention Control and Counter Measures Plan have all been submitted. Together these plans will ensure the protection of groundwater and control of surface runoff. Jim Rada, Environmental Health Manager, 6 Hunter Mesa Compressor Station BOCC 1/17/11 KE responded to the referral, EXHIBIT L, which stated a Stormwater Permit was not provided in the submittal documentation. The Applicant has subsequently provided a copy of the Construction Discharge Permit which is attached as EXHIBIT 0. The drainage plan proposes construction of a detention pond that will adequately serve the entire site with a capacity of 2,100 cubic feet. With provision of the detention pond the engineer has determined that the rate of runoff shall not exceed pre-development rate for the 2-year and 25-year storm events.

Determination of the existing environmental conditions on the parcel to be developed and the effects of development on those conditions, including: a. Determination of the long term and short term effect on flora and fauna. 7 Hunter Mesa Compressor Station BOCC 1/17/11 KE b. Determination of the effect on significant archaeological, cultural, palentalogical, historic resources. c. Determination of the effect on designated environmental resources, including critical wildlife habitat. (1} Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments. e. Spill Prevention Control and Counter Measures plan, if applicable. Staff Comments: Disturbance of approximately 1.62-acres will result in minimal impacts on wildlife habitat and vegetation on the site and no cultural resources have been identified as existing on the property. Operation of the facility may result in minimal impacts such as loss in wildlife habitat and revegetation will improve the existing conditions of the site. HRL Compliance Solutions, Inc. has prepared a Spill Prevention Control and Counter Measures Plan (SPCC) for this compressor station facility in compliance with requirements established by United States Environmental Agency (EPA) regulations. These plans are required if: the facility could reasonably be expected to discharge oil into on upon the navigable waters of the U.S.; the total aboveground storage capacity exceeds 1,320 gallons; and the completely buried storage capacity exceeds 42,000 gallons. This site will have a potential maximum capacity of 50,400 gallons and individual storage volumes of 16,800 gallons each, therefore the requirement to develop, implement and maintain such a plan. A regional director of the EPA is notified in the event of spills that exceed 1,000 gallons of oil or when a facility may discharge more than 42 gallons of oil in two discharge events within a 12-month period of time. The COGCC requires reporting of spills/releases of produced fluids exceeding five (S) barrels. The Rifle Fire Protection District responded to the request for comments, EXHIBIT K, with several recommended changes to the SPCC including reference to the Fire Protection District rather than Grand Valley which may change depending on the location of the facility. Other recommended changes include reporting protocols and provision of Hazardous Materials Declaration Forms to the FPD. Staff has included these requests as a condition of approval. 9. Traffic. Assessment of traffic impacts based upon a traffic study prepared in compliance with Section 4-502(1}. Staff Comments: A Basic Traffic Study has been prepared which indicates that traffic volumes associated with the operation of the facility will be minimal (one construction one ton truck per 8 Hunter Mesa Compressor Station BOCC 1/17/11 KE day), however traffic will increase for a 12-week period during which the facility will be constructed. During that timeframe the Applicant has asserted that they will obtain any oversize, overweight/over-length permits that may be required, safety signage will be installed stating "Trucks entering the roadway", and flagging will be conducted during delivery of the compressors or any other deliveries by semi-tractor trailer. 10. Nuisance. Impacts an adjacent land from generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. Staff Comments: NOISE: Jeff Cerjan of Hankard Environmental conducted a Noise Compliance Analysis for this proposed use. Findings were that the noise levels from the proposed facility will be in compliance with COGCC Rule 802. The proposed acoustic enclosures for each of the compressor/engine/cooler packages will have sound-absorbing interior walls, sound attenuated ventilation openings and sound-attenuated engine cooling air intake and discharge openings. The engine exhausts include silencers. These mitigation methods will allow the facility to operate in compliance with both daytime and nighttime standards established by the COGCC. Jim Rada, Environmental Health Manager, responded to the referral, EXHIBIT L, that the noise analysis utilized light industrial standards (for the receptor property) due to the existing adjacent uses, however the historic County review standard has been to impose the more restrictive residential noise levels when the facility is located within a residential zone district. Further, the review of noise standards is conducted 350' from the noise source, not the property line. Given the significant noise abatement methods proposed for this site staff is confident that this site can adequately meet the more restrictive residential standard. Staff has included a provision in the condition related to common industrial nuisance standards (condition 6.a.) that the residential noise standards are applicable to this site. VIBRATION: Maintenance and operation of the facility requires that vibration be minimized to prevent increased expenditures and downtime for maintenance. The facility will be operated so that ground vibration is not perceptible at any boundary point of the property. AIR QUALITY: A Colorado Department of Public Health and Environment (CDPHE), Air Quality Control Division (AQCD) Construction Permit application has been submitted for the facility which included a comprehensive list of equipment proposed to be located on the site. Jim Rada, Environmental Health Manager, responded that a condition be recommended regarding obtaining the Construction Permit prior to construction of the facility. Other air quality measures relate to the potential VOC emissions from the three condensate storage tanks proposed to be located onsite. It is estimated that the VOC emissions will be greater than 20 tpy therefore dedicated vapor combustors will be installed to destroy the flash vapors. 9 Hunter Mesa Compressor Station BOCC 1/17/11 KE Uncontrolled VOC emissions from each of the dehydration units are >15 tpy which require controls, Applicant proposes routing emissions to a thermal oxidizer which operates with a minimum destruction efficiency of 99%. Fugitive dust will result primarily during the construction phase of the facility however there will be ongoing dust issues that results from continued use of the access drive. The traffic generation of the facility (post-construction) is minimal, however some measure of mitigation should be incorporated into the project. The Applicant has represented that: "The access road would be graveled and treated to retard dust (with water or chemical dust suppressant) as necessary." 11. Reclamation Plan. A reclamation plan consistent with the standards in Section 7-212. Staff Comments: A revegetation plan has been submitted, reviewed, and accepted by the County Vegetation Manager, Steve Anthony. Security to assure completion of the revegetation will result in proposed condition requiring that a bond in the amount of $5,480.00 must be submitted prior to issuance of the Land Use Change Permit ($4,000/acre). Staff is recommending that this be included as a condition of approval. B. Section 7-100 GENERAL APPROVAL STANDARDS FOR LAND USE CHANGE PERMITS 1. Section 7-101 Compliance with Zone District Use Restrictions Staff Comments: The site will comply with dimensional standards of the Rural zone district and the use is permissible upon issuance of a Land Use Change Permit through Limited Impact review. Z. Section 7-102 Compliance with Comprehensive Plan and Intergovernmental Agreements Staff Comments: Pursuant to existing IGA's the application was referred to the City of Rifle, however no response was received. The site is contained within Study Area 2 of the Comprehensive and designated as outlying residential on the Proposed Land Use Districts map and the site appears to comply with the Commercial and Industrial Uses Policies, Goals and Objectives. 3. Section 7-103 Compatibility Staff Comment: Given the two existing compressor stations in the vicinity, as well as pipelines and well pads, it would appear that the proposed use is compatible with other uses in the area. 4. Section 7-104 Sufficient Legal and Physical Source of Water Staff Comments: No potable water is proposed to be provided. 10 5. Section 7-105 Adequate Water Supply Staff Comments: Not applicable. Hunter Mesa Compressor Station BOCC 1/17/11 KE 6. Section 7-106 Adequate Water Distribution and Wastewater Systems Staff Comments: A portable toilet is proposed to be located on-site to serve the transient truck /inspector that may visit the site. There will be no permanent employees located at this facility. 7. Section 7-107 Adequate Public Utilities Staff Comments: Public utilities are adequate to serve the proposed use. 8. Section 7-108 Access and Roadways Staff Comments: Adequate access appears to exist to the site. 9. Section 7-109 No Significant Risk from Natural Hazards Staff Comments: Other than expansive soils there have been no identified natural hazards associated with the site. Documentation provided by the Applicant has not identified any other natural hazards and the County area of mapping for geologic hazards does not extend as far south as the proposed project area. C. Section 7-200 GENERAL RESOURCE PROTECTION STANDARDS FOR LAND USE CHANGE PERMITS 1. Section 7-201 Protection of Agricultural Lands 11 Staff Comment: There are no significant agricultural lands affected by this proposal. The map, left, identifies areas that may be considered significant agricultural lands if irrigated. The proposed site, indicated by the green dot, does not fall within that area. 2. Section 7-202 Protection of Wildlife Habitat Areas Hunter Mesa Compressor Station BOCC 1/17/11 KE Staff Comment: The area is mapped as Mule Deer and Elk winter concentration area and Severe Winter Range. Proposed mitigation includes fencing of the compressor station and related facilities area. 3. Section 7-203 Protection of Wetlands and Waterbodies Staff Comment: Not Applicable 4. Section 7-204 Protection of Water Quality from Pollutants Staff Comment: The Application contained a Spill Prevention Plan and Stormwater Management Plan both of which specify and provide protection of water quality. A Construction Stormwater Discharge Permit is attached as EXHIBIT 0. 5. Section 7-205 Erasion and Sedimentation Staff Comment: The submitted Stormwater Management Plan adequately addresses this issue. 6. Section 7-206 Drainage & Section 7-207 Stormwater Run-Off Staff Comments: A Master Drainage Report was prepared for the project area and adequately addresses existing drainage and proposed methods to detain runoff to meet the required standard that post-construction rates not exceed the pre-development runoff rates for both 2-year and 25-year events. 7. Section 7-208 Air Quality Staff Comments: A construction air permit application has been included in the submittal documentation. The Applicant has stated that air quality will not be reduced below acceptable levels by the proposed use. Adequate fugitive dust mitigation measures have been provided. 8. Section 7-209 Areas Subject to Wildfire Hazards Staff Comments: The area is shown on Wildfire Hazard Maps as a low to moderate rating for wildfire. Existing grasses on-site would provide the only fuel in the event of a wildfire. 9. Section 7-210 Areas Subject to Natural Hazards and Geologic Hazards Staff Comments: There are no known hazards in this area that would preclude this use. 12 Hunter Mesa Compressor Station BOCC 1/17/11 KE 10. Section 7-211 Areas with Archeological, Paleontological or Historicallmportonce Staff Comments: No historic sites or resources have been identified on the property. 11. Section 7-212 Reclamation Staff Comments: An adequate revegetation plan has been submitted. Staff is recommending a condition of approval regarding the submittal of security to assure proper revegetation of the site. The applicable standard for security is $4,000 per acre resulting in a security amount for this site at $5,480.00. SECTION 7-810 ADDITIONAL STANDARDS APPLICABLE TO INDUSTRIAL USE. A. Enclosed Building. Staff Comments: Each compressor unit is enclosed within a sound-attenuated structure and the site will be fenced. B. Loading and Unloading. Staff Comments: All loading and unloading will occur within the site. C. Outdoor Storage Facilities. All outdoor storage facilities for fuel, raw materials and products shall be screened by natural topography or enclosed by a fence or wall adequate to conceal such facilities from adjacent property. 1. All outside storage abutting or facing a lot in a residential or commercial zone shall be screened by natural topography or enclosed by a site-obscuring fence to obstruct the storage area from view. The fence shall be of material and design that will not detract from adjacent residences. Staff Comments: The site will be enclosed by a chain-link fence. D. Industrial Wastes. Staff Comments: Industrial wastes will be properly disposed of in compliance with regulatory requirements. E. Sound. Staff Comments: The submitted Sound Survey adequately demonstrates that the site can comply with established maximum noise levels. However the sound survey stated this fact based upon the maximum levels of the light industrial standards, rather than the residential standards which have been determined by past County policy. It appears that the facility could still comply with these more stringent standards. 13 F. Ground Vibration. Hunter Mesa Compressor Station BOCC 1/17/11 KE Staff Comments: The Application states that the site can and will operate in compliance with established regulations on vibration. G. Interference, Nuisance or Hazard. Staff Comments: Applications must demonstrate the ability to comply with standards required by Federal, State and Local regulations. Continued operation in compliance of these standards is a typical condition of approval. VI.

The following are my comments: 1. 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. EM D'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 2 . J. -Both the SPCC plan and the SWMP plan need the signatures of the engineer of record or company representative. 3. Rifle Fire has experienced some delays in gas industry delaying calling 911 immediately. The EAP Quick reference chart does a good job of making this a priority. We would suggest changes in the following areas: a. J.-SPCC plan: i. Section 7.2-change step# 7 to step# 2 ii. . Section 7.2 & 8.4 -Change all phones numbers for Rifle Fire to "dial 911 or 970-625-8095/office number-970 625-1243". Although we staff our stations 24/7, the response crews are not at the stations 24/7 and thus no one would answer 970-625-1243. iii. Attachment H-1-lA-Add "dial 911or call 970-625-8095" government contacts b. J. Emergency Action Plan iv. H-1-IV -Add fire district(s) to i. Pg 1-Change non-emergency number to 970-625-8095/office number-970 625-1243 ii. Section IV -pg 3-1st appropriate action is "dial 911" in 1. 1st sentence 2. bulleted item number 3 iii. section VI remove the "or" in "and I or contact 911" iv. Quick Reference-change fire non emergency phone number to "970-625-8095 or office number-970 625-1243" 4. J-SPCC section 8.4-change heading that says Grand Valley to just Fire Protection District since Grand Valley FPD covers the Parachute Area. If appropriate add Burning Mountains FPD which covers the Silt /New Castle areas. 5. J. Emergency Action Plan-section IV-last line change "All fires, even those that have been extinguished, must be reported" to "All fires, even those that have been extinguished, must be reported the fire department". This is in line with state statue. 6. Attached are our haz mat declaration forms that need to be filled out and returned to us at Antero's earliest convenience but no later than when the plant is operational. This is for our response crews 7. Two areas that we are working with other gas companies are: a. What quantities of a spill require a fire district response? An example would be in the SPCC plan-section 7.2 -step 9 where it states "a minor amount of oil". The fire district recognizes there are the federal and state reportable quantities. b. Is production water a hazardous material? The fire district recognizes that the exact makeup can vary greatly. Our current policy is to treat all production water as hazardous.

I hope I'm not too late. 1. I reviewed the application for an Air Quality permit that has been submitted to CDPHE. Air quality construction permits must be obtained before construction of the facility can begin. This is stated on page 14 of the Environmental Impact Study included in the application. I recommend a condition on the permit requiring this. 2. Regarding noise, the application indicates that this facility would be constructed in a light industrial zone per COGCC Rules. Does the County classify this area as light industrial or rural agricultural? If the latter, then a lower noise standard would be applied, correct? I do not question the work of the sound engineer's modeling effort but perhaps a validation of the modeling when the site is fully operational would be appropriate to avoid or mitigate later complaints. 3. Although the application implies that there is a CDPHE Stormwater Permit for this particular site (or area-wide permitL I could not locate an actual permit in the materials. It was not included in Appendix B to the Stormwater Management Plan. Adequate information should be submitted to confirm that this site is covered under an area-wide permit or an individual site permit. ffhanks for the opportunity to review this application.

The review letter is dated December 17, 2010. We have been asked by Sopris Engineering to provide comment relative to review Comment No. 3. This letter provides our response to review Comment No. 3. The comment is "The proposed drainage and slope between the proposed compressor buildings is very flat (0.5%}. This slope will be difficult to construct and maintain as a gravel surface and does not likely match the drainage recommendations of the Geotechnical engineer." We reviewed the most current drainage plan and discussed the proposed grading between the proposed compressor buildings with Sopris Engineering, LLC. Grading will include slopes down and away from the buildings at+/-2 percent to the north or south. The ground surface will then transition to a slope to the east at 0.5 percent. Our recommendations were for positive drainage away from the buildings. The plans do show positive drainage away from the buildings. The gravel surface cross-section will be 4 inches of Class 6 aggregate base course over 8 inches of Class 3 aggregate base course on a geotextile fabric. We understand that the building will have gutters and downspouts. The inclusion of gutters and downspouts to collect and remove rain and snowmelt from the roof will significantly limit wetting of the area between the buildings. The roof runoff water should be discharged to the east of the buildings. Assuming positive 234 Center Drive I Glenwood Springs, Colorado 81601 Telephone: 970-945-2809 Fax: 970-945-7411 drainage between the buildings, gutters and leaders is maintained, we believe the areas between the buildings will not be problematic to the planned site usage. We believe the current plans are appropriate. Some stabilization may be required after significant precipitation events.
