Sector-Specific Benchmark Values and Effluent Limitations. Discharges may be subject to requirements for more than one sector or subsector.
|H1 Coal Mines and Related Area||Solids, Total Suspended (TSS)||100 mg/L 1|
|Aluminum, Total (as Al)||0.75 mg/L|
|Iron, Total (as Fe)||1.0 mg/L|
|pH 2||6.0-9.0 SU|
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.
2For purposes of benchmark pH monitoring, the Permittee is required to report instantaneous results only, and not a calculation of pH averages. pH measurements are logarithmic, and the Agency will be performing a logarithmic average for this parameter using the instantaneous results submitted.
