| Engineer | Form: (06) 401862237 03/21/2019 | Plugging
1) Provide 48 hour notice of plugging MIRU via electronic Form 42.
2) Properly abandon flowlines as per Rule 1105. File electronic Form 42 once abandonment complete. Within 30 days of an operator completing abandonment requirements for an off-location flowline or crude oil transfer line the operator must submit a Flowline Report, Form 44.
3) Plugs and squeezes will be placed as stated in the Plugging Procedure section of the approved NOIA unless revised by COA or prior approval from COGCC is obtained. Confirm COAs have been met on the Form 6 SRA
4) Place a 50' plug (minimum) at the surface, both inside the inner most casing and in all annular spaces. Confirm cement to surface in all strings during cut and cap. All other cement plugs, without mechanical isolation, will be a minimum of 100'.
5) If there is any bradenhead pressure reported on the pre-plugging Form 17, contact COGCC engineering for verification of plugging procedure.
6) COGCC Change: CIBP at 50’ to 80’, cement to surface.

| Engineer | Form: (06) 401862237 03/21/2019 | Bradenhead Testing
Prior to starting plugging operations a bradenhead test shall be performed if there has not been a reported bradenhead test within the 60 days immediately preceding the start of plugging operations.
1) If, before opening the bradenhead valve, the beginning pressure is greater than 25 psi, sampling is required.
2) If pressure remains at the conclusion of the test, or if any liquids were present during the test, sampling is required.
The Form 17 shall be submitted within 10 days of the test. Sampling shall comply with Operator Guidance - Bradenhead Testing and Reporting Instructions. If samples are collected, copies of all final laboratory analytical results shall be provided to the COGCC within three (3) months of collecting the samples.
If there is a need for sampling, contact COGCC engineering for verification of plugging procedure.

| Engineer | Form: (06) 401862237 03/21/2019 | Venting
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.
