The Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers published a proposed rule that aims to clarify the definition of “waters of the U.S.” under the Clean Water Act and significantly expand federal control of land and water resources across the nation—creating additional permitting and regulatory requirements. The public has until Oct. 20 to submit written comments on the proposed rule.

The EPA recently released a draft scientific report on the connectivity of water that is intended to guide the proposed rule. As part of the Waters Advocacy Coalition, Associated Builders and Contractors submitted comments on the report, stating it provides no scientific support to make distinctions between significant connections and non-significant connections.

The rule will not be finalized until an independent peer review by the Scientific Advisory Board Panel is complete. For more information, visit www.epa.gov.
