CWA Public Notice - Big Muddy Creek


U.S. Environmental Protection Agency, Region 7
Water, Wetlands, and Pesticides Division
901 North 5th Street
Kansas City, Kansas 66101


Section 303(d) of the Clean Water Act (CWA), 33 USC § 1313(d)(1)(C), and the U.S. Environmental Protection Agency's (EPA) implementing regulation, 40 CFR § 130.7(c)(1), require the establishment of Total Maximum Daily Loads (TMDLs) for waters identified as not meeting water quality standards under authority of § 303(d)(1)(A) of the CWA. Each of these TMDLs is to be established at a level necessary to implement applicable water quality standards with seasonal variations and a margin of safety, accounting for lack of knowledge concerning the relationship between pollutant loading and water quality.

To meet the milestones of the 2001 Consent Decree, American Canoe Association, et al. v. EPA, No. 98-1195-CV-W, in consolidation with No. 98-4282-CV-W, February 27, 2001, EPA is establishing this TMDL. The EPA is developing this TMDL in cooperation with the state of Missouri, and Missouri may submit and EPA may approve another TMDL for this water at a later time.

The waterbody from the 1998 and 2002 Missouri 303(d) lists that will be addressed by the TMDL is Big Muddy Creek, water body identification number 436. Big Muddy Creek is a small northwestern Missouri tributary of the Grand River. The headwaters of Big Muddy Creek lie between Gilman City and Jameson in northern Daviess County. It flows south to the confluence with the Grand River, about 5 miles southeast of Gallatin, Missouri. Eight miles of lower Big Muddy Creek are listed as impaired by sediment for its warm water aquatic life use. The impairment of this water body is based on exceedence of the specific criteria contained in Missouri's WQS, 10 CSR 20-7.031(3)(A), (C) and (G). Public comment for this TMDL ends on September 25, 2006.

Persons wishing to comment on this proposed TMDL or to offer new data or information regarding the proposed TMDL are invited to send comments to the EPA, Region 7, Water, Wetlands, and Pesticides Division, 901 North 5th Street, Kansas City, Kansas, 66101, ATTENTION: Mr. Nathaniel Dunbar II, Water Quality Management Branch.

A copy of the proposed TMDL can be obtained through the Internet or by contacting Mr. Dunbar via electronic mail at dunbar.nate@epa.gov or via fax request at 913-551-7982. On the web, the TMDL is found at: http://www.epa.gov/region07/water/tmdl_public_notice.htm.
