Update on Proposed Aethon Energy (Moneta Divide Gas Field) Discharge Permit - Online Comments are now being accepted

The WDEQ’s Wyoming Pollutant Discharge Elimination System (WYPDES) Program regulates the discharge of pollutants from point sources to ensure the protection of Wyoming’s surface waters. Operators of point source discharges are required to receive coverage under WYPDES discharge permits. Prior to issuing a permit, the WYPDES Program issues a 30-day public notice to inform interested parties of the proposed permit, and offers an opportunity to the public to provide written comments regarding the proposed permit.

On March 15, 2019 WDEQ’s Water Quality Division (WQD) issued a 30-day public notice requesting public comments on its proposed renewal of WYPDES permit WY0002062 for expanding the current discharge of produced water from the Moneta Divide Gas Field operated by Aethon Energy. Since then, DEQ has extended the public comment period to July 5, 2019.
