WASHINGTON, Sept 4 (Reuters) – The U.S. Environmental Protection Agency and Army Corps of Engineers on ​Friday proposed an additional rulemaking ‌to get more public input about how to define which U.S. waters should face federal regulation that can withstand ‌future ​legal challenges.

• A ⁠Supplemental Notice of ⁠Proposed Rulemaking will gather more comment on defining “waters of the United States” (WOTUS)

• The agencies also seek comment ​on new alternatives for two key terms: “relatively permanent” waters and “continuous ⁠surface connection” wetlands

• ⁠The EPA last year ​proposed narrowing the definition of waters ​that can be federally regulated to ‌comply with the 2023 Sackett vs EPA Supreme Court decision, a move cheered by Republican lawmakers ⁠in agricultural states and some farmers and landowners

• “The EPA’s goal is a durable WOTUS ⁠definition ‌that follows the law ⁠and ends burdensome regulatory ​uncertainty,” ‌said EPA Administrator Lee Zeldin

• ​Once the ⁠supplemental proposal is published in the Federal Register, the agencies will accept public comments for 30 days
