NSSGA Comments to EPA and Army Corps of Engineers on Updated Definition of ‘‘Waters of the United States,” Supplemental Proposed Rulemaking

The National Stone, Sand & Gravel Association (NSSGA) is pleased to provide comments to the U.S. Environmental Protection Agency (EPA) and the U.S. Army Corps of Engineers (Corps) (the Agencies) on the Updated Definition of Waters of the United States (WOTUS). NSSGA is a member of the Waters Advocacy Coalition and incorporates its comments by reference. NSSGA commends the Agencies on this proposal. NSSGA agrees with the approach this rule takes to provide the clarity and certainty needed by officials of the Agencies and other government entities, the regulated community and the public, based on the Supreme Court's unanimous Sackett v. EPA opinion.
