Invitation for Feedback on Directives 055 and 058, AER Bulletin 2021-24

Link to Bulletin Summarized

Oil and Gas


The AER requested feedback on new editions of Directive 055: Storage Requirements for the Upstream Petroleum Industry and Directive 058: Oilfield Waste Management Requirements for the Upstream Petroleum Industry. These directives were updated to incorporate the storage of large volumes of water such as produced water, water-based flowback, and oilfield landfill leachate in storage devices for reuse in hydraulic fracturing. The directives were revised to provide greater clarity and to remove redundant and outdated requirements.

Directive 055 now includes technical requirements for engineered containment ponds and bladders with structural frames and expanded requirements for aboveground synthetically lined walled storage systems.

Directive 058 now includes storage of water for reuse in hydraulic fracturing as a waste storage activity.

Several ancillary documents were also consolidated in the directives, including addendums, interim directives, informational letters, reports, and bulletins.

A comment form is available on the Directive 055 and Directive 058 webpages. Feedback will be accepted through Sunday, July 25, 2021.
