7/21/2016 | 604c.(2).E. Multiwell Pads: This 2A application is for a 5-well pad. PDC Energy considered all options for this area, including the Landowner's preference. There are 2 1/2 sections of flood plain in this area which made it very difficult to find a location for these wells. Leasehold by other operaters prevented us finding a location to the south. We could not drill to the east due to the new County Road 49. There are multiple homes located to the west and north. We worked hard to keep most of our operations in the farm field and out of wetlands areas. This field has an existing PDC well and battery which will be removed, along with the existing access, which is currently close to several homes. A new access will be built over a 1/4 of a mile away in an effort to avoid disturbing as many homes as possible. There is a new DCP Gas line closeby, which will keep our sales line short and out of the wetlands area. There is a Bald Eagle nest(s) located to the south west and we planned this location to keep to the north east as far as possible, so as not to disturb the eagles.

7/21/2016 | 604.c.(2).W. Site Specific Measures: Lights should be turned downward and away from building units within the 1,000 foot buffer area. PDC will employ practices for control of fugitive dust caused by operations, these include but are not limited to the use of speed restrictions and regular road maintenance. When necessary, PDC will conduct dust mitigation on gravel roads, place road-base where allowed by surface owners, around tanks/wellheads to minimize dust, and will apply water to roads and locations when dry. During winter operations normal dust abatement is not provided unless requested by surrounding land owners. Fugitive dust control will be incorporated as needed during all other months of drilling and completion operations. |

7/21/2016 | 805.b(1)-(c) Odors and Dust: Oil and gas facilities and equipment will operate in a manner that odors and dust do not constitute a nuisance or hazard to public welfare. Odors: Oil and gas operations will be in compliance with the Department of Public Health and Environment, Air Quality Control Commission, Regulation No. 2 Odor Emission, 5 C.C.R. 1001-4, Regulation No. 3 (5 C.C.R. 1001-5), and Regulation No. 7 Section XVII.B.1 (a-c) and Section XII. Dust; PDC will employ practices for control of fugitive dust caused by operations include but not limited to the use of speed restrictions, regular road maintenance, restriction of construction activity during high-wind days, and silica dust controls when handling sand used in hydraulic fracturing operations. When necessary, PDC coordinates dust mitigation with the county on gravel roads, places road base where allowed by surface owner around tanks and wellheads to minimize dust, and will water the roads and locations when dry. In addition, automation is used on all new wells to minimize truck traffic.

Access Roads: PDC will utilize an improved lease access road off of County Road 58 (paved) for all heavy truck traffic and rig moves along with drilling operations and maintenance equipment. The lease access road will be properly constructed and maintained to accommodate for local emergency vehicle access. PDC will employ practices for control of fugitive dust caused by operations, these include but are not limited to the use of speed restrictions and regular road maintenance. When necessary, PDC will conduct dust mitigation on gravel roads, place road-base where allowed by surface owners, around tanks/wellheads to minimize dust, and will apply water to roads and locations when dry.

7/21/2016 | "604c.(2).A. Noise: WELL PAD: PDC has conducted baseline noise surveys for all drilling rigs that are being contracted and has also conducted a baseline noise survey for hydraulic fracture stimulation operations on a representative horizontal well. These baseline surveys are utilized for site specific noise modeling to determine if any mitigation measures are warranted. A review was conducted to identify potential receptors within 1000 feet of the proposed pad site. There are three (3) building units of concern located 532' NW, 565' SW and 674' NW. Light and sound mitigation will be installed to the Northwest and Southwest of the proposed location. Methods of noise mitigation shall include but not be limited to hay bales, sound walls, or customized semi-trailers. PRODUCTION FACILITIES: It is not anticipated that noise mitigation will be necessary at the proposed tank battery location. After construction is completed, equipment installed and production begins, noise levels will be assessed to determine if mitigation measures will be required to be compliant with Rule 802.

7/21/2016 | Prior to drilling operations, Operator will perform an anti-collision scan of existing offset wells that have the potential of being within close proximity of the proposed well. This anti-collision scan will include definitive MWD or gyro surveys of the offset wells with included error of uncertainty per survey instrument, and compared against the proposed wellpath with its respective error of uncertainty. If current surveys do not exist for the offset wells, Operator may have gyro surveys conducted to verify bottomhole location. The proposed well will only be drilled if the anti-collision scan results indicate that there is not a risk for collision, or harm to people or the environment. For the proposed well, upon conclusion of drilling operations, an as-constructed gyro survey will be submitted to COGCC with the Form 5.
