(A) Industrial waste survey information will be used to develop contributor-specific local limits when necessary to ensure that the POTW's maximum allowable headworks loading are not exceeded for particular pollutants of concern. Contributor-specific local limits for appropriate pollutants of concern shall be included in wastewater permits. The POTW Director may impose mass-based limits in addition to, or in place of, concentration-based limits. An industrial waste survey is required prior to a contributor discharging wastewater containing in excess of the following average sanitary wastewater pollutant concentrations:
Average Sanitary Wastewater Pollutant Concentrations
|
Average Sanitary Wastewater Pollutant Concentrations
| |
BOD | 250 mg/l |
TSS | 250 mg/l |
TKN | 40 mg/l |
Ammonia | 25 mg/l |
Arsenic | 0.003 mg/l |
Cadmium | 0.003 mg/l |
Chromium | 0.05 mg/l |
Copper | 0.061 mg/l |
Cyanide | 0.015 mg/l |
Lead | 0.049 mg/l |
Mercury | 0.0003 mg/l |
Molybdenum | 0.060 mg/l |
Nickel | 0.021 mg/l |
Selenium | 0.006 mg/l |
Silver | 0.005 mg/l |
Zinc | 0.175 mg/l |
(B) When unauthorized wastewater discharges are identified, the POTW director may:
(1) Reject the waste; and/or
(2) Require pretreatment to the levels specified in this subchapter as acceptable for discharge to the public sewers; and/or
(3) Require control over the quantities and rates of discharge to the levels specified in this chapter; and/or
(4) Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes, fees or sewer charges.
(5) If the POTW Director permits or requires the pretreatment of waste flow, the design and installation of the plants and equipment shall be subject to the review and approval, in writing, of the POTW Director, and subject to the requirements of all applicable codes, ordinances and laws.
