EPA Sends NPDES NPRM to OMB

Yesterday, the OMB’s Office of Information and Regulatory Affairs (OIRA) announced that it had received a notice of proposed rulemaking (NPRM) from the EPA on “Updates to the National Pollutant Discharge Elimination System Definitions and Exclusions”. 

This rulemaking was not listed in the Spring 2025 Unified Agenda, so the planned scope of this rulemaking is not readily available. I would assume, however, that this NPRM is part of the Administration’s deregulatory agenda. 

I would not expect to cover this rule in any detail, but at a minimum I will be mentioning the publication of the NPRM in the appropriate Short Takes post.
