3/15/2010 | Pit Design, Construction, and Monitoring Requirements General Requirements for Pits: Pits shall not be constructed on springs, seeps, or other surface water features. If groundwater is encountered during pit construction activity, pit construction shall cease and the location shall be reclaimed. An alternate location or an alternate plan (e.g., use of a closed loop and/or semi-closed loop system) must be approved by the Director before resuming operations. All pits, including drilling pits, in the Area of Concern must be lined, as discussed below under “Pit Design and Construction” and in accordance with COGCC Rule 904. No portion of any pit shall be constructed on fill material, unless the pit and fill slope are designed and certified by a Professional Engineer, subject to review and approval by the Director prior to construction of the pit. The construction and lining of the pit shall be supervised by a professional engineer or their agent. An as-built construction report is required for pits which are designed and certified by a Professional Engineer. The as-built construction report shall be submitted with a Form 4 (Sundry Notice – Report of Work Done) to COGCC’s environmental staff for approval prior to using the pit. Produced water shall be treated in accordance with Rule 907. before being placed in a properly-permitted pit. Storage of produced water in drilling pits in anticipation of upcoming drilling or completion activities is not allowed for a period longer than seven (7) calendar days. Pit Design and Construction: If site-specific conditions do not allow for compliance with these minimum requirements, then the operator must submit a pit design which is certified by a Professional Engineer, subject to review and approval by the Director prior to construction of the pit. The pit design shall be submitted with a Form 4, Sundry Notice. Liner systems for all pits, including drilling Pits shall meet the minimum requirements of COGCC Rules 904.b. or 904.c. Drill cuttings may be used as an alternative liner foundation material (COGCC Rule 904.c.(3)), provided that a double synthetic liner system is used and the recycled drill cuttings meet the applicable standards of Table 910-1. It is the operator’s responsibility to design and construct a liner system to contain fluids in the pit without compromising the integrity of the liner(s). Pit sidewall slopes shall not be steeper than 1 vertical to 2 horizontal to facilitate installation of the bedding materials and the synthetic liner(s). If sidewall slopes exceed 1 vertical to 2 horizontal, then the operator must submit a site-specific pit design that will minimize the likelihood of damage to the liner by sharp rock edges and any other material protruding from the sidewalls. The pit design must be certified by a Professional Engineer, subject to review and approval by the Director prior to construction of the pit. The pit design shall be submitted with a Form 4, Sundry Notice. As a Condition of Approval for pits requiring a Form 15, the Director may require other additional protective measures. These measures may include but are not limited to increased record-keeping requirements, monitoring systems, and leak detection systems. In making such a determination, the Director shall consider the surface and subsurface geology, the existence of ground water, the quality of the produced water, and the hydraulic conductivity of the surrounding soils and bedrock, the depth to ground water, and the distance to surface water and water wells. Hydrotesting: After installation of the uppermost liner and prior to using any lined pit, the synthetic liner(s) shall be tested by filling the pit with at least eight (8) feet of fresh water, measured from the base of the pit (not to exceed the two (2) foot freeboard requirement). The operator shall monitor the pit for leaks for a period of seventy-two (72) hours prior to draining the pit and commencing operations. Hydrotest monitoring results must be maintained by the operator for the life of the pit and provided to the Director upon request. If leaks are observed, the operator must suspend operations and notify the Director within twenty-four (24) hours. The operator must fix any leaks and repeat hydrotests as described above. Operations shall not commence until a successful hydrotest is performed with no leaks observed. Pit Monitoring (in addition to the requirements of COGCC Rule 902.b. the operator shall): Monitor pit fluid levels using a pit level indicator at least once every twelve (12) hours whenever fluid is present in the pit in quantities greater than de minimis amounts. The monitoring frequency shall increase to once every six (6) hours when the pit is being actively used for drilling, completion or production operations. Monitoring results must be documented and records maintained by the operator in accordance with COGCC Rule 205 and provided to the Director upon request. Stop using the pit as soon as practicable, if there is any observed loss of integrity from the pit liner or if the operator suspects a loss of more than five hundred (500) barrels of liquid from the pit, based on fluid level measurements or throughput measurements. The operator must notify the Director in accordance with COGCC Rule 906. The pit contents shall be removed as soon as practicable, the pit will be inspected and the extent of impact, if any determined and remediated, repairs to the pit liner system shall be made or a replacement liner system installed, and use of the pit shall not resume until a successful hydrotest is performed and the results have been submitted with a Form 4, Sundry Notice to the Director for approval. Suspension of Use: If operations are suspended and the pit is not in use for more than seven (7) calendar days, then fluids in the pit must be removed such that only de minimis amounts of fluids are left in the pit to hold down the synthetic liner(s). After removing fluids, the operator shall continue to inspect the pit and record any observed leaks, punctures or tears at least once every twenty-four (24) hours while use of the pit is suspended. The pit shall be inspected by the operator prior to re-use. If any leaks, punctures or tears are observed, then the synthetic liner must be replaced and hydrotested prior to resuming operations. If operations are suspended for more than six (6) months, then the pit shall be closed, unless specifically approved by the Director. |

10/12/2016 | The moisture content of water/bentonite based mud (WBM) generated drill cuttings managed onsite shall be kept as low as practicable to prevent accumulation of liquids greater than de minimis amounts. After drilling and completion operations have been completed, any WBM drill cuttings that will remain on the well pad location (cuttings management area, the cut portion of the pad, cuttings trench, dry cuttings drilling pit), must meet the applicable standards of Table 910-1. No liners are allowed to be disposed of with the drill cuttings. After the drill cuttings have been amended (if necessary) and placed on the well pad, sampling frequency of the drill cuttings (to be determined by the operator) shall be representative of the material left on location. No offsite disposal of cuttings to another oil and gas location shall occur without prior approval of a Waste Management Plan (submitted via a Form 4 Sundry Notice) specifying disposal location and waste characterization method.
The nearby hillside must be monitored for any day-lighting of drilling fluids throughout the drilling of the surface casing interval.
Flowback and stimulation fluids must be sent to enclosed tanks, separators, or other containment/filtering equipment before the fluids can be placed into any pipeline storage vessel, or other open top containment located on the well pad; or into tanker trucks for offsite disposal. No open top tanks can be used for initial flowback fluids containment. The flowback and stimulation fluid tanks, separators, or other containment/filtering equipment must be placed on the well pad in an area constructed to be sufficiently impervious to contain any spilled or released material. No additional downgradient berming is required if operator constructs a sufficiently sized perimeter berm.

10/12/2016 | Operator must ensure secondary containment for any volume of fluids contained at the well site during drilling and completion operations (as shown on the Construction Layout Drawings and Facility Layout Drawing attachments); 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 fluid containment/control as well as stormwater management for the control of run-on and run-off) sufficiently protective of nearby surface water. Any berm reconstructed at the well pad location will be stabilized, inspected at regular intervals as required by CDPHE (at least every 14 days and after precipitation events), and maintained in good condition. The design/build of any perimeter berm shall be sized, constructed, and compacted sufficiently to contain fluids during drilling operations, as well as all fluids contained in temporary frac tanks during completion operations.
The location is in an area of moderate to high run-on/run-off potential; therefore standard stormwater BMPs must be implemented; prior to, during, and after construction, as well as during operations; at this location to insure compliance with CDPHE and COGCC requirements and to prevent any stormwater run-on and /or stormwater run-off.
The access road will be maintained as to not allow any sediment to migrate from the access road to nearby surface water or any drainages leading to surface water.
Strategically apply fugitive dust control measures, including encouraging established speed limits on private roads, to reduce fugitive dust and coating of vegetation and deposition in water sources.
Berms or other containment devices shall be constructed to be sufficiently impervious (corrugated steel with poly liner) to contain any spilled or released material around permanent condensate and produced water storage tanks. |
