Effluent limits and exceedances

42Pollutants on file
42Under a numeric limit
33With a violation of any kind
7With an effluent exceedance

An effluent exceedance is a discharge monitoring report value over the permit’s numeric limit (EPA’s violation code E90). A violation of any kind also counts a report not filed. Each row is EPA’s own count for that pollutant.
