Total Maximum Daily Load Reports (TMDLs) are a report that identifies loading reductions of pollutants necessary to achieve chemical water quality standards (WQS). The TMDL reports will also identify surrogate measures that may be used to assess the likelihood that impaired waters will be restored to a level of biological performance that will achieve WQS.
This page is focused on TMDL activity in Central District Office. For more information on the statewide TMDL program, go here: http://www.epa.ohio.gov/dsw/tmdl/index.aspx
