12/20/2018 | 1) Venting to maintain the bradenhead pressure below 0.25 times the surface casing setting depth (TVD) in psi is approved. Perform annual Bradenhead tests reported on a Form 17 and an annual update sundry with the duration of venting or number of times the annulus was vented.
2) COGCC staff encourages the use of a combustor for vented bradenhead gas when feasible without the use of supplemental fuel for the combustor. An enclosed flare shall be used, unless an open flare is specifically allowed by Colorado Department of Public Health and Environment (CDPHE) Regulation 7.
3) Comply with any CDPHE, Air Pollution Control Division rules or requirements for all atmospheric discharges.
4) Any liquids blown down are to be collected, stored, handled, and treated or disposed as E&P waste per COGCC’s 900 series rules.
5) Annular spaces may be tied to low pressure sales lines with COGCC engineering approval on a Sundry Notice, Form 4, describing equipment configuration, proper pressure regulation and check valves. At least one check valve is required for annular spaces that are tied to sales. Maintain equipment for pressure regulation and check valves in good working order.
6) Submit a Form 4 Sundry within 60 days providing the COGCC a measured rate of vented bradenhead gas.

09/18/2025 | Due to proximity to a mapped wetland and surface water, operator will use secondary containment for all tanks and other liquid containers. Operator will implement stormwater BMPs and erosion control measures as needed to prevent sediment and stormwater runoff from entering the wetland and surface water.

10/22/2025 | 1) Provide electronic Form 42 Notice of MIRU 2 business days ahead of operations and electronic Form 42 Notice of Plugging Operations 48 hours prior to mobilizing for plugging operations. These are two separate notifications, required by Rules 405.e and 405.l.
2) Prior to placing cement above the surface casing shoe. Verify that all fluid (liquid and gas) migration has been eliminated. If evidence of fluid migration or pressure remains, contact ECMC Engineer for an update to plugging orders.
3) After surface plug and prior to cap, verify isolation by either a 15 minute bubble test or 15 minute optical gas imaging. If there is indication of flow contact ECMC Engineering. Provide a statement on the 6SRA which method was used and what was observed. Retain records of final isolation test for 5 years
4) With the Form 6 SRA operator must provide written documentation which positively affirms each COA listed above has been addressed.

10/22/2025 | Consistent with Rule 911.a, a Form 27 must be approved prior to cut and cap, conducting flowline abandonment, or removing production equipment. Allow 30 days for Director review of the Form 27; include the Form 27 document number on the Form 44 for offsite flowline abandonment (if applicable) and on the Form 6 Subsequent.
Properly abandon flowlines per Rule 1105. If flowlines will be abandoned in place, include with the Form 27: pressure test results conducted in the prior 12 months as well as identification of any document numbers for a ECMC Spill/Release Report, Form 19, associated with the abandoned line.
