EFFLUENT LIMITATION GUIDELINES (ELGs)

New Source Performance Standards

New source performance standards (NSPS) represent the best available
demonstrated control technology standards. US EPA has established NSPS
guidelines for the industries found in the Table below. The intent of NSPS
guidelines is to set effluent limitations that represent state-of-the-art treatment
technology for new sources.3

a “discharge of pollutants,” the construction of which commenced: (1) After promulgation of
standards of performance under section 306 of CWA which are applicable to such source, or (2)
After proposal of standards of performance in accordance with section 306 of CWA which are
applicable to such source, but only if the standards are promulgated in accordance with section
306 within 120 days of their proposal as defined in 40 C.F.R section 122.26.
