Dear Ms. Willhite:
The United States Environmental Protection Agency (U.S. EPA) has reviewed the final Total
Maximum Daily Load (TMDL) for the impaired segments in the East Fork Kaskaskia River
watershed (SOB, ROZY, SOG, and SOF) including supporting documentation and follow up
information. IEPA's submitted TMDLs address the presence of elevated levels of manganese
that impairs the Public Water Supply Use in Farina Lake, Kinmundy Lake, Kinmundy Borrow
Pit, and Kinmundy Lake New (segments SOB, ROZY, SOG, and SOF) in the East Fork
Kaskaskia River watershed. Based on this review, U.S. EPA has determined that lllinois's
TMDLs for manganese meet the requirements of Section 303(d) of the Clean Water Act and U.S.
EPA's implementing regulations at 40 C.F.R. Part 130. Therefore, U.S. EPA hereby approves
lllinois's 4 TMDLs for the impaired segments in the East Fork Kaskaskia River watershed (SOB,
ROZY, SOG, and SOF). The statutory and regulatory requirements, and U.S. EPA's review of
lllinois's compliance with each requirement, are described in the enclosed decision document.
We wish to acknowledge lllinois's effort in this submitted TMDL, and look forward to future
TMDL submissions by the State oflllinois. If you have any questions, please contact Mr. Kevin
Pierard, Chief of the Watersheds and Wetlands Branch at 312-886-4448.
