Effluent limits and exceedances
- 47Pollutants on file
- 18Under a numeric limit
- 33With a violation of any kind
- 2With 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.
