Ohio EPA Releases Draft TMDL

for the Big Darby Creek Watershed


On May 16, 2005, Ohio EPA released a draft version of the Big Darby Creek Total Maximum Daily Load (TMDL) report, an important document which sets goals for protection of Big Darby Creek and its tributary streams.  This is necessary because Big Darby Creek and its tributaries are not meeting the goals of the Clean Water Act. 


"In the simplest terms, a TMDL is a cleanup plan for a watershed that is not meeting water quality standards. A TMDL is defined as a calculation of the maximum amount of a pollutant that a waterbody can receive and still meet water quality standards and an allocation of that quantity among the sources of the pollutant. Ultimately, the goal of Ohio’s TMDL process is full attainment of Water Quality Standards (WQS)."  (from Chapter 1 of "Draft for Public Comment: Big Darby Creek Watershed TMDLs.")


An overview of this draft TMDL is included in the Ohio EPA's fact sheet.


You can download the draft TMDL at Ohio EPA's WWW site:

The public review period ends on July 15, 2005.
