Overview of Discharge Limits and Permits

Municipal discharge requirements typically cover prohibited discharges, concentration and loading limits for parameters such as biochemical oxygen demand (BOD), total suspended solids (TSS), pH, oil and grease, heavy metals and specific toxic substances. Limits and permit conditions are imposed to protect the sewer collection system, pumping stations and the wastewater treatment plant.
