The Total Maximum Daily Load (TMDL) Process

The TMDL process serves as a roadmap for water body restoration by focusing on improving water quality in impaired surface waters identified in the biennial State of Hawaii Water Quality Monitoring and Assessment Report. TMDLs identify sources of pollution within a watershed and determine pollutant load reductions required for a water body to meet water quality standards. The TMDL process is a vital component of implementing water quality improvement projects under Clean Water Act Section 319(h) grants, administered by the Department of Health, Polluted Runoff Control Program.

Additional information on TMDLs can be found on the U.S.Environmental Protection Agency TMDL website.
