The Upper Little Miami River Watershed TMDL

Background

The Upper Little Miami River Total Maximum Daily Load (TMDL) report was approved by U.S. EPA on July 2, 2002.  It is the third Ohio TMDL project report approved by U.S. EPA under Section 303(d) of the Clean Water Act. TMDLs identify and evaluate water quality problems in impaired water bodies and propose solutions to bring those waters into attainment.

The final report reflects comments made during the first and second public comment periods; the significant differences from the second draft of the report are:

• the margin of safety discussion was expanded and clarified
• the POTW suggested implementation plan was included
• some of the NPDES language was clarified
• Appendix E includes the comments from the second draft period as well as the first

The first draft was different from the original document that was public noticed in early 2001; it was changed in the following ways: elimination of total nitrogen allocations, addition of permit limits for point sources, and more detail on implementation.
