Clean Water Act Section 303(d): Availability of List Decisions

This action announces the availability of EPA decisions identifying water quality limited segments and associated pollutants in Arizona to be listed pursuant to Clean Water Act section 303(d)(2), and requests public comment. Section 303(d)(2) requires that states submit and EPA approve or disapprove lists of waters for which existing technology- based pollution controls are not stringent enough to attain or maintain state water quality standards and for which total maximum daily loads (TMDLs) must be prepared. On November 16, 2004, EPA partially approved and partially disapproved Arizona's 2004 submittal. Specifically, EPA approved Arizona's listing of 53 waters, associated pollutants, and associated priority rankings. EPA disapproved Arizona's decisions not to list 19 water quality limited segments and associated pollutants, and additional pollutants for 8 water bodies already listed by the State. EPA identified these additional water bodies and pollutants along with priority rankings for inclusion on the 2004 Section 303(d) list. EPA is providing the public the opportunity to review its decisions to add waters and pollutants to Arizona 2004 Section 303(d) list, as required by EPA's Public Participation regulations. EPA will consider public comments in reaching its final decisions on the additional water bodies and pollutants identified for inclusion on Arizona's final lists.
