NOTICE OF TOTAL MAXIMUM DAILY LOAD DOCUMENT:
AN OPPORTUNITY FOR
PUBLIC COMMENT
The South Dakota Department of Environment and Natural Resources (DENR) is announcing the availability of the following Total Maximum Daily Load (TMDL) document for review and comment.
Big Sioux River Segment 01 Escherichia coli TMDL, Codington, Grant, Day and Roberts Counties, South Dakota
This TMDL document was developed at a watershed scale with public involvement in accordance with section 303(d) of the federal Clean Water Act.
The 2018 South Dakota Integrated Report for Surface Water Quality Assessment identified the Big Sioux River segment 01 as not supporting the designated use of limited contact recreation due to increased levels of Escherichia coli bacteria. This segment was placed on the 303(d) list of impaired waterbodies and requires a TMDL. A TMDL defines the existing pollutant loading of all waste load allocations from point source discharges and remaining load allocations from nonpoint sources, plus a margin of safety to account for uncertainty. A TMDL establishes the amount of pollutant loading reduction needed to bring a waterbody into compliance with water quality standards to protect the designated uses. A TMDL document also includes information about watershed characteristics, data collection, pollutant sources, seasonality, public participation and implementation strategy.
The TMDL document is available at DENR’s One-Stop Public Notice page at the following weblink: http://denr.sd.gov/public/default.aspx. Persons are encouraged to submit comments electronically through the One Stop Notice page by using the online comment form accessible via the “Comment Deadline” link. A copy of the TMDL document may also be requested by calling 1-800-438-3367, emailing denrinternet@state.sd.us, or by mail at the address below. Comments can be submitted via email or by writing to the respective addresses. The department must receive comments by March 23, 2020.
