Effluent limits and exceedances

94Pollutants on file
94Under a numeric limit
4With a violation of any kind
4With 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; the 60 with the most exceedances of 94 are shown.
