Abstract

The original TMDL document, submitted by the Iowa Department of Natural Resources to Region 7 of the U.S. Environmental Protection Agency, was approved on August 30, 2012. The 2012 TMDL targeted the following pollutants: Algae, low dissolved oxygen, organic enrichment, and total phosphorus. The Iowa DNR submitted this TMDL for pH on January 21, 2021 that builds on the information and analysis from the September 2012 TMDL. Following comments from the EPA, IDNR resubmitted the TMDL on February 11, 2021. This TMDL does not supersede the 2012 TMDL, but adds to it. This decision document only addresses the TMDL for pH. The EPA’s decision document for the 2012 TMDL contains the rationale for the approval of the original TMDL. The EPA approves this TMDL for pH.
