(Kansas City, Kan., May 23, 2006) – EPA has announced its amended decision on Iowa’s 2004 Section 303(d) List of impaired waters, based on public comments.

Under Section 303(d) of the 1972 Clean Water Act, states, territories, and authorized tribes are required to develop lists of impaired waters every two years. By law, EPA must approve or disapprove those 303(d) lists.

EPA partially approved and partially disapproved Iowa’s 2004 Section 303(d) List on November 14, 2005, when our decision document and supporting documentation were mailed to the state.

This original decision included adding 20 water bodies to the list. Of those 20 water bodies, six were removed by the state in its final 2004 list and were restored to the list by EPA. EPA held a public comment period from November 18 through December 19, 2005, seeking written comments on our original decision.

Based on our review, EPA is amending its decision by not adding Buffalo Creek, the South Skunk River, and the East Fork Wapsipinicon River to Iowa’s 2004 303(d) list. Our rationale for not adding those three water bodies is included in the amended decision letter. The other 17 water bodies added in our original decision will remain on the list.

The amended decision letter and Responsiveness Summary to Comments will be available by May 24 on the
EPA Region 7 Web site:, and the list and supporting information on our original decision is still available at that Web site.
