(A) To implement the general and specific discharge prohibitions listed in this chapter, industrial user-specific local limits will be developed ensuring that the POTW's maximum allowable headworks loading is not exceeded for particular pollutants of concern for each industrial user. Where specific local limits are not contained for a given parameter or pollutant in an industrial user permit, the following limits will apply to all users:
250 mg/l | BOD |
250 mg/l | TSS |
40 mg/l | TKN |
0.003 mg/l | arsenic |
0.003 mg/l | cadmium |
0.090 mg/l | copper |
0.035 mg/l | cyanide |
0.049 mg/l | lead |
5.00 mg/l | MBAS |
0.0003 mg/l | mercury |
0.170 mg/l | nickel |
50.0 mg/l | O/G |
0.005 mg/l | silver |
0.05 mg/l | total chromium |
0.340 mg/l | zinc |
0.100 mg/l | phenol |
(B) Industrial user-specific local limits for appropriate pollutants of concern shall be included in wastewater permits and are considered pretreatment standards. The POTW Director may impose mass limits in addition to, or in place of, the concentration-based limits above in accordance with categorical standards.
(C) Any violation of this section shall be subject to the penalties as described in § 51.999 herein.
