Dear Ms. Willhite:
The United States Environmental Protection Agency (U.S. EPA) has conducted a complete
review ofthe final Total Maximum Daily Load (TMDL) submittal, including supporting
documentation and information, for Salt Fork Vermilion River segments BPJ-lO, BPJ-08 and
BPJ-03, which are located in Champaign and Vermilion Counties, Illinois. The TMDLs are for
nitrates and fecal coliform. Based on this review, U.S. EPA has detennined that Illinois' TMDLs
for Salt Fork Vermilion River segments BPJ-lO, BPJ-08 and BPJ-03 meet the requirements of
Section 303(d) of the Clean Water Act (CWA), and U.S. EPA's implementing regulations at 40
C.F.R. Part 130. Therefore, by this letter, U.S. EPA hereby approves these four TMDLs which
address seven impairments. The statutory and regulatory requirements, and U.S. EPA's review
of Illinois' compliance with each requirement, are described in the enclosed decision document.
We appreciate your hard work in this area and the submittal of the TMDL as required. If you
have any questions, please contact Mr. Dean Maraldo, TMDL Program Manager at
312-353-2098
Sincerely yours,
,
