Administrator Wheeler Issues Proposed Rule on Clean Water Act Quality Certification In Charleston, South Carolina

Public comment period begins following publication in the Federal Register; public meeting and hearing scheduled for Sept. 5-6, 2019

Charleston, S.C. (August 9, 2019) - Today, the U.S. Environmental Protection Agency (EPA) issued a proposed rule to implement Section 401 of the Clean Water Act (CWA). EPA Administrator Andrew Wheeler made the announcement at the Council of Manufacturing Associations Summer Leadership Conference in Charleston. The proposed rule seeks to increase the transparency and efficiency of the 401 certification process and to promote the timely review of infrastructure projects while continuing to ensure that Americans have clean water for drinking and recreation.

“Under President Trump, the United States has become the number one oil and gas energy producer in the world, while at the same time continuing to improve our air quality,” said EPA Administrator Andrew Wheeler. “Our proposal is intended to help ensure that states adhere to the statutory language and intent of Clean Water Act. When implemented, this proposal will streamline the process for constructing new energy infrastructure projects that are good for American families, American workers, and the American economy.” 

In April, President Trump issued an executive order and directed the administration to take appropriate action to accelerate and promote the construction of pipelines and other important energy infrastructure. The president’s executive order directs EPA to consult with states and tribes on reviewing and updating guidance and regulations related to Section 401 of the CWA.

Section 401 of the CWA gives states and authorized tribes the authority to assess potential water quality impacts of discharges from federally permitted or licensed infrastructure projects that may affect navigable waters within their borders. The EPA’s existing certification rules have not been updated in nearly 50 years and are inconsistent with the text of CWA Section 401, leading to confusion and unnecessary delays for infrastructure projects. With today’s action, EPA is proposing to modernize and clarify the timeline and scope of CWA Section 401 certification review and action to be consistent with the plain language of the CWA.

EPA will accept public comment on the proposed rule for 60 days following publication in the Federal Register.

Background information:

EPA is proposing this rule in response to President Trump’s Executive Order 13868, “Promoting Energy Infrastructure and Economic Growth.” EPA was directed to first revise guidance on the CWA Section 401 certification process and then to propose new rules to implement CWA Section 401 by Aug. 8, 2019. EPA engaged in formal consultation with state, local and tribal partners, as well as other federal agencies, to develop this proposed rule. Under the executive order, the EPA is scheduled to finalize this rule in May 2020.
