"Special Conditions" Section of the Permit
Percent removal: Another typical requirement for a municipality is commonly known as the "percent removal" requirement. Basically, the municipality must "remove" over 85% of BOD and total suspended solids. This requirement is not typically on the Effluent Limitations page but is usually a "Special Condition."
Note: some facilities are exempt for the suspended solids removal requirement if they have an oxidation pond, but none are exempt from the BOD removal requirement. Ask EPD if the facility has an oxidation pond.
