The Upper Klamath and Lost River TMDL was first issued in May 2010. At that time the U.S. Environmental Protection Agency approved all of the components of the TMDL except for temperature. During this time it was also noted that seven entities affected by the TMDL in Klamath County petitioned the DEQ director to reconsider various components of the TMDL. The director granted the reconsideration based on these petitions.
Subject to public review and comment, DEQ intends to reissue the TMDL and Water Quality Management Plan. Part of the review process is an opportunity for public comment, based on the TMDL document, WQMP and other DEQ information.
