What’s a TMDL?What’s a TMDL? ““Total Maximum Daily Load” Total Maximum Daily Load”

How much pollutant a stream can How much pollutant a stream can receive and remain healthyreceive and remain healthy

TMDL is a pollution budget – prescribes TMDL is a pollution budget – prescribes reduction of pollutants that result in the reduction of pollutants that result in the restoration of an impaired stream restoration of an impaired stream

TMDL development required by TMDL development required by Clean Water Act for all Clean Water Act for all impairedimpaired streamsstreams
