Ninth Circuit Affirms Lower Court Decision to Apply Constructive Submission Doctrine and Compel EPA to Issue a Temperature TMDL for Rivers in Washington and Oregon
Under the Clean Water Act (CWA), a TMDL establishes the maximum amount of each pollutant that an impaired water segment can receive while still meeting identified water quality standards. After EPA receives a proposed TMDL from the state, it has a non-discretionary duty to either “approve or disapprove” the TMDL. See 33 U.S.C. § 1313(d)(2). If EPA approves the TMDL, it becomes effective. If EPA disapproves the TMDL, it must produce and issue its own TMDL within thirty days. Just before the close of 2019, the Ninth Circuit affirmed the decision of the District Court for the Western District of Washington to compel the Environmental Protection Agency (EPA) to issue a temperature total maximum daily load (TMDL) for the Columbia and Snake Rivers. Columbia Riverkeeper v. Wheeler, No. 18-35982 (9th Cir., Dec. 20, 2019). At issue in the litigation was whether the “constructive submission doctrine” applied when Washington and Oregon failed to submit required temperature TMDLs and whether that failure triggered a non-discretionary duty for EPA to issue the TMDL itself.
