07/11/2016 | 1)Operator shall comply with the most current revision of the Northwest Notification Policy.
2) Operator shall provide cement coverage from the production casing shoe (5+1/2" First String) to a minimum of 200' above the surface casing shoe to provide full isolation of the Coalmont Formation. Verify production casing cement coverage with a cement bond log. |

05/10/2019 | 1) Operator shall comply with the most current revision of the Northwest Notification
Policy.
2) Operator shall provide cement coverage from the production casing shoe (5 1/2" First
String) to a minimum of 200' above the surface casing shoe to provide full isolation of
the Coalmont Formation. Verify production casing cement coverage with a cement bond
log.
3) Oil-based drilling fluid is to be used only after all fresh water aquifers are
covered.
4) The Operator shall monitor the bradenhead pressure of all wells under Operator’s control within 300 feet of the well which is to be treated, provided such other wells penetrate the productive zone which is to be treated. This offset monitoring will be required for any well stimulated on this pad.
If at any time during the Treatment or the 24-hour post-stimulation period, the bradenhead annulus pressure of the Treatment well or any of the monitored offset wells increases by more than 200 psig, the Operator of the well being treated shall notify the Director by Form 42, as soon as practicable, but no later than twenty-four (24) hours following such incident. Within fifteen (15) days after the occurrence, the Operator or Adjacent Operator(s), as the case may be, shall submit a Sundry Notice, Form 4, giving all details, including corrective actions taken.

05/13/2019 | Drilling/Completions: The following conditions of approval (COAs) will apply:
•A closed loop system must be implemented during drilling (as indicated on the Form 2 and Form 2A).
•Water/Bentonite-Based Drilling Mud (WBM) and Oil-Based Drilling Mud (OBM) Generated Solids / Cuttings Management and Offsite Disposal.
•The moisture content of all drill cuttings managed onsite shall be kept as low as practicable to prevent accumulation of liquids greater than de minimis amounts.
•All Oil Based Mud (OBM)-generated cuttings must be segregated from Water/Bentonite Based Mud (WBM)-generated cuttings and managed separately on the well pad. All OBM-generated drill cuttings must be kept in tanks or containers, or placed on a lined and bermed portion of the well pad prior to disposition.
•The trucks used for offsite disposal of OBM-generated drill cuttings must have a liner and the operator must implement measures (covers, misting, etc.) to reduce dust and PM emissions during transport from the well site to the commercial disposal facility.
•Flowback and stimulation fluids must be sent to enclosed tanks, separators, or other containment or filtering equipment before the fluids can be placed into any pipeline, storage vessel, or into tanker trucks for offsite disposal. No open top tanks can be used for initial flowback fluids containment. Secondary containment for flowback storage tanks shall meet the requirements of Rule 906.d.(1). |
