05/02/2013 | PIPELINE COAs:
Operator shall pressure test pipelines in accordance with Rule 1101.e.(1) prior to putting into initial service.
Operator must implement best management practices to contain any unintentional release of fluids along all portions of the surface pipeline route where temporary pumps and other necessary equipment are located.
Operator must routinely inspect the entire length of the surface pipeline to ensure integrity.
Operator must ensure 110 percent secondary containment for any potential volume of fluids that may be released from the surface pipeline at all stream, intermittent stream, ditch, and drainage crossings.
Operator will utilize, to the extent practical, all existing access and other public roads, and/or existing pipeline right-of-ways, when placing/routing the surface pipelines. This will reduce surface disturbance and fragmentation of wildlife habitat in the area. |

05/02/2013 | SITE SPECIFIC COAs:
Notify the COGCC 48 hours prior to start of pad construction, rig mobilization, spud, and start of hydraulic stimulation operations using Form 42 (the appropriate COGCC individuals will automatically be email notified, including the LGD for hydraulic stimulation operations).
Operator must implement best management practices to contain any unintentional release of fluids, including any fluids conveyed via temporary surface pipelines
Operator must ensure 110 percent secondary containment for any volume of fluids contained at well site during drilling and completion operations; including, but not limited to, construction of a berm or diversion dike, diversion/collection trenches within and/or outside of berms/dikes, site grading, or other comparable measures (i.e., best management practices (BMPs) associated with stormwater management) sufficiently protective of nearby surface water. Any berm constructed at the well pad location will be stabilized, inspected at regular intervals (at least every 14 days), and maintained in good condition.
The location is in an area of moderate to high run-on/run-off potential; therefore standard stormwater BMPs must be implemented at this location to insure compliance with CDPHE and COGCC requirements and to prevent any stormwater run-on and /or stormwater run-off.
The moisture content of any drill cuttings in a cuttings pit, trench, or pile shall be as low as practicable to prevent accumulation of liquids greater than de minimis amounts. At the time of closure, if drill cuttings are to remain/disposed of onsite, they must also meet the applicable standards of table 910-1.
Flowback and stimulation fluids must be sent to tanks, separators, or other containment/filtering equipment before the fluids can be placed into any pipeline, storage vessel, or lined pit (only if an amended Form 2A has been submitted/approved and a Form 15 Earthen Pit Permitted has been submitted/approved) located on the well pad; or into tanker trucks for offsite disposal. The flowback and stimulation fluid tanks, separators, or other containment/filtering equipment must be placed on the well pad in an area with additional downgradient perimeter berming. The area where flowback fluids will be stored/reused must be constructed to be sufficiently impervious to contain any spilled or released material.
Berms or other containment devices shall be constructed to be sufficiently impervious (preferably corrugated steel with poly liner) to contain any spilled or released material around crude oil, condensate, and produced water storage tanks.
Prior to drilling, operator shall collect surface water samples from Ripley Gulch to the south-southeast (one upgradient and one downgradient from the well pad location), if water is present. After 90 days, but less than 180 days of completion of the proposed wells a “post-completion” test shall be performed for the same analytical parameters listed below and repeated once between 60- and 72- months. If the wells are non-producing wells, then the 60- to 72-month sample will not be required. If no significant changes from the baseline have been identified after the 60- to 72-month sample, no further testing shall be required. Additional “post-completion” test(s) may be required if changes in water quality are identified during follow-up testing. At a minimum, the surface water samples will be analyze for the following parameters: pH, specific conductance, total dissolved solids (TDS), dissolved gases (methane, ethane, propane), alkalinity (total bicarbonate and carbonate as CaCO3), major anions (bromide, chloride, fluoride, sulfate, nitrate and nitrite as N, phosphorus), major cations (calcium, iron, magnesium, manganese, potassium, sodium), other elements (barium, boron, selenium and strontium), total petroleum hydrocarbons (TPH) and BTEX compounds (benzene, toluene, ethylbenzene and xylenes). Field observations such as odor, water color, sediment, bubbles, and effervescence shall also be documented. The location of the sampled Water Sources shall be surveyed in accordance with Rule 215. Copies of all test results described above shall be provided to the COGCC Director and the landowner where the water quality testing is located within three (3) months of collecting the samples used for the test. The analytical data and surveyed locations shall also be submitted to the Director in an electronic data deliverable format.
Prior to pad construction or start of drill, is there is not sufficient water present in Ripley Gulch, operator shall provide documentation (dated photographs) to the COGCC via a Form 4 Sundry Notice, attention: Dave Kubeczko (email: dave.kubeczko@state.co.us) requesting relief from this COA. |

5/18/2013 | PLANNING BMP's
* Share/consolidate corridors for pipeline ROWs to the maximum extent possible.
* Maximize the utility of surface facilities by developing multiple wells from a single pad (directional drilling), and by co-locating
multipurpose facilities (for example, well pads and compressors) to avoid unnecessary habitat fragmentation and disturbance
of additional geographic areas.
* Minimize newly planned activities and operations within 300 feet of the ordinary high water mark of any reservoir, lake,
wetland, or natural perennial or seasonally flowing stream or river.
* Locate roads outside of drainages where possible and outside of riparian habitat.
* Avoid new surface disturbance and placing new facilities in key wildlife habitats in consultation with CDOW.
* Minimize the number, length, and footprint of oil and gas development roads
* Use existing roads where possible
* Combine utility infrastructure (gas, electric, and water) planning with roadway planning to avoid separate utility corridors
* Combine and share roads to minimize habitat fragmentation
* Where possible, consolidate pipeline and existing roadways, or roadways that are planned for development
* Design roads with visual and auditory buffers or screens (e.g., topographic barriers, vegetation, and distance).
* Maximize the use of directional drilling to minimize habitat loss/fragmentation
* Maximize use of remote telemetry for well monitoring to minimize traffic
* Maintain undeveloped areas within development boundaries sufficient to allow wildlife to persist within development
boundaries during all phases of construction, drilling, and production.
* Minimize the duration of development and avoid repeated or chronic disturbance of developed areas. Complete all
anticipated drilling within a phased, concentrated, development area during a single, uninterrupted time period.
