02/01/2019 | 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.
