|Y1 Fabricated Rubber Products||Zinc, Total (as Zn)||0.234 mg/L 1|
|Lead, Total (as Pb)||0.164 mg/L 1|
|Solids, Total Suspended (TSS)||100 mg/L 2|
|Y2 Plastic Products||Solids, Total Suspended (TSS)||100 mg/L 2|
1The benchmark values of some metals are influenced by water hardness. For these parameters, the Permittee may determine the hardness of the stormwater discharges to identify the applicable ‘hardness range’ for determining their benchmark value. See Table 4 of Appendix B for hardness dependent benchmark values in accordance with Minn. R. 7050.0222 and Minn. R. 7052.0100.
2If 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.
