Effluent limits and exceedances
- 70Pollutants on file
- 27Under a numeric limit
- 68With a violation of any kind
- 17With 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 70 are shown.
