DEQ Release – In December 2018, the U.S. Environmental Protection Agency approved Oregon’s 2012 Clean Water Act Section 303(d) List of impaired water bodies that need pollution reduction plans, called total maximum daily loads or TMDLs. DEQ uses the 303(d) list to determine requirements for water quality permits and total maximum daily loads. EPA added 285 water bodies to the list, removed 56 water bodies from the list, and reclassified 714 stream segments affected by ongoing litigation over temperature water quality standards.
