SiteTitle | • | Load Reduction Strategy and TMDL Draft: Indian Creek, Dago Slough and Prairie Creek | [X] |
| | 1: | | Title: | | | | | Volume/Number: | 2010 July 1 | | | | Issuing Agency: | | | | | Description: | This report contains a Total Maximum Daily Load (TMDL) allocation for manganese and a Load Reduction Strategy (LRS) for phosphorus and total suspended solids. TMDLs include allocations for both nonpoint and point sources. Illinois EPA applies TMDLs towards those parameters with numeric water quality standards, which have been adopted by the Illinois Pollution Control Board. LRSs are based on targets for the watershed and focus on nonpoint source controls. The reason for this is that the pollutants in question (Total Suspended Solids (TSS) and Total Phosphorous (P)) do not currently have a numerical standard in place. In the case of Phosphorous, a state standard does exist for lakes, however, Indian Creek, Dago Slough, and Prairie Creek are small streams and therefore a P standard does not exist. Recent water quality sampling showed one exceedence of the Mn standard by 0.01mg/l; a TMDL will be developed for Mn. We have still approached this project as a traditional TMDL but will refer to it as a Load Reduction Strategy (LRS) for P and TSS. | | | | Date Created: | 07 21 2010 | | | | Agency ID: | | | | | ISL ID: | 000000043264 Original UID: 22772 FIRST WORD: Load | |
