Abstract

This Cedar Lake Total Maximum Daily Load (TMDL) for atrazine is being established in accordance with Section 303(d) of the Clean Water Act (CWA), which requires a TMDL for each water body on a state's Section 303(d) List of impaired waters, herein referred to as 303(d) List, in accordance with requirements of Section 303 of the CWA; Water Quality Planning and Management Regulations, 40 Code of Federal Regulations (CFR) Part 130; and United States Environmental Protection Agency (EPA) guidance. EPA is establishing this TMDL to fulfill the requirements of the Consent Decree established as part of the Sailors, Inc., Mississippi River Revival and Sierra Club v. EPA Consolidated Case No. 98-134-MJM. Cedar Lake (04-LDM- 03085-L_0) is included in the Consent Decree because it was on the Iowa (IA) 1998 303(d) List due to atrazine concentrations that exceeded IA Water Quality Standards (WQS). Cedar Lake is also included on the Iowa 2006 303(d) List because of atrazine impairment.
