Background

3⁄4 Effluent Limitations Guidelines (ELG)

– National standards, based on performance of treatment an

technologies, for wastewater discharges to surface water amunicipal sewage treatment plants

– Developed on an industry-by-industry basis

– Represent pollutant reductions that are economically achie

an industry using the best available technology.

3⁄4 ELG implementation 

– Direct dischargers: Implemented through National Polluta

Discharge Elimination System (NPDES) program Discharge Elimination System (NPDES) program

– Indirect dischargers: Implemented through national pretre

program
