SCS Technical Bulletin: 2021, EPA Seeks Feedback On Inactive Surface Impoundments At Inactive Electric Utilities

SCS periodically prepares Technical Bulletins to highlight items of interest to our clients and friends who have signed up to receive them.  We also publish these on our website at

Our most recent Bulletin entitled EPA Seeks Feedback On Inactive Surface Impoundments at Inactive Electric Utilities summarizes the EPA’s request for comments and information pertaining to inactive impoundments at inactive facilities.

Operators and owners who may be affected by forthcoming decisions around inactive CCR surface impoundments include electric utilities and independent power producers who generate CCR within the North American Industry Classification System (NAICS) code 221112. Though the EPA states “other types of entities … could also be regulated” and advises those wanting to confirm if the regulation applies to them to read the applicability criteria and comment. Landowners, with a legacy surface impoundment on their property purchased from a utility, will want to review the proposed definitions closely.



SCS Engineers will continue to post timely information, resources, and presentations to keep you well informed. These include additional guidance, industry reaction, and webinars for our clients.
