On Friday, August 9, the Environmental Protection Agency (“EPA”) unveiled a pre-publication version of a notice of proposed rulemaking (“NOPR”) to clarify state water quality certification (“certification”) procedures under Section 401 of the Clean Water Act (“CWA”) to allow for increased regulatory certainty in federal licensing and permitting activities, and particularly authorization of infrastructure projects.  EPA Administrator Andrew Wheeler announced on Friday that the “proposal is intended to help ensure that states adhere to the statutory language and intent of Clean Water Act.”  The NOPR proposes substantive changes to the scope of state water quality certification authority under the CWA and the procedures governing these certifications, focusing on the plain language of the statute and at times departing from prior case law precedent.

Significant components of the NOPR are summarized below.  EPA has established a 60-day period for public comment on the proposed rule, from the date of publication in the Federal Register.  In light of the substantial modifications to the scope, substance and procedures related to state water quality certification, the NOPR presents a unique opportunity for utilities, manufacturers, developers, and other regulated business entities to help shape a significant regulatory program.
