(January 25, 2018, 12:30 PM EST) -- BOSTON — A First Circuit U.S. Court of Appeals panel on Jan. 24 affirmed the dismissal of two lawsuits brought by environmental groups against the U.S. Environmental Protection Agency, holding that the agency’s approval of total maximum discharge limits (TMDLs) of stormwater for bodies of water in Rhode Island and Massachusetts did not trigger a duty to provide notice to potential dischargers (Conservation Law Foundation v. U.S. Environmental Protection Agency, Nos. 17-1166, 17-1354, 1st Cir., 2018 U.S. App. LEXIS 1734)....
