SUMMARY: This notice announces the availability of EPA's proposed decision identifying water quality limited segments and associated pollutants in Indiana to be listed pursuant to the 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 May 8, 2013, EPA partially approved and partially disapproved Indiana's 2010 303(d) list submittal. Specifically, EPA approved Indiana's listing of certain water quality limited segments and associated pollutants (Table 1 inAppendix A1 of EPA's decision document for Indiana's 2010 303(d) list). EPA disapproved Indiana's decision not to list water quality limited segments for certain metal pollutants.
After conducting a complete review, EPA identified the waterbodies and associated metal pollutants (e.g. aluminum, iron, copper, lead, and zinc) to be added to Indiana's 2010 303(d) list (Table 12 in Appendix A1 of EPA's decision document). EPA is providing the public the opportunity to review its proposed decision to add waters and pollutants to Indiana's 2010 Clean Water Act Section 303(d) list. EPA will consider public comments in reaching its final decision on the additional waterbodies and pollutants identified for inclusion on Indiana's final 2010 303(d) list.
