total daily maxiumum load (tMDL) Implementation Plans
When water quality monitoring data shows that state waters do not meet water quality standards, clean-up plans called Total Maximum Daily Loads (TMDLs) are developed by DEQ to determine the total amount of a pollutant that a waterbody can receive and still meet water quality standards. These waters are called “impaired” and are listed in the Virginia Water Quality Assessment Integrated Report. The overall goal of a clean-up plan is to restore and maintain water quality standards. Pollutant reductions from nonpoint sources are implemented through TMDL Implementation Plans and nonpoint source grant programs that fund voluntary practices. The following sub-watersheds have TMDL Implementation Plans linked here:
