Sector-Specific Benchmark Values and Effluent Limitations: Sector - S2: Discharges may be subject to requirements for more than one sector or subsector.
Link to this table

Subsector Parameter Benchmark Values
S2 Airports that use less than 100,000 gallons of glycol-based deicing/anti-icing chemicals and/or less than 100 tons of urea on an average annual basis. Solids, Total Suspended (TSS) 100 mg/L 1
5-Day Carbonaceous, Biochemical Oxygen Demand (CBOD5) 25 mg/L
Chemical Oxygen Demand (COD) 5-Day Carbonaceous, Biochemical Oxygen Demand 120 mg/L
Nitrogen, Ammonia, Total (as N) 2.8 mg/L

1If the Permittee is required to comply with Appendix A, part F.1, the benchmark value for Solids, Total Suspended (TSS) is 65 mg/L, instead of 100 mg/L.
