2) Submit annual updates (requests to flare) to COGCC on Form 4’s (Sundry Notices), which discuss whether or not any new gathering systems or increased development of the field have changed pipeline economics such that installation of a new pipeline would be an economically viable option in lieu of continued flaring. The annual update shall include gas analysis for hydrogen sulfide.
3) Comply with any Colorado Department of Public Health and Environment, Air Pollution Control Division rules or requirements for all atmospheric discharges.
4) An enclosed flare shall be used, unless an open flare is specifically allowed by CDPHE’s Regulation 7. |

3) Check bradenhead pressure prior to MIRU. Perform a bradenhead test if pressure is greater than 50 psi, submit results electronically on a Form 17, and contact COGCC area engineer.
4) Operator shall implement measures to control unnecessary and excessive venting, to protect the health and safety of the public, and to ensure that vapors and odors from well plugging operations do not constitute a nuisance or hazard to public welfare.

7) Test the 7” casing to at least 300 psi after setting CIBP with cement top at 4950’. Contact COGCC engineer if pressure test fails for revised plugging orders.
8) Insure that there is no pressure or fluid migration on the casing or bradenhead prior to squeezing at 878’. Contact COGCC engineer if not the case for revised plugging orders.
9) COGCC Change: Increase size of squeeze at 878’ to 100 sx.
10) COGCC Change: Add a 50 sx squeeze at 2000'.
