The following pollutant limits are established to protect against pass through and interference.
(A) Non-toxic pollutants.
POLLUTANT (Total unless otherwise listed) | CONCENTRATION Instantaneous Daily Maximum (mg/l) |
Oil and Grease - at non-food service establishment (FSE) or food manufacturing sites | 200 |
Oil and Grease - at FSE | 200 |
(1) The village reserves the right to apply the FSE Local Limit as appropriate above at an end-of-pipe discharge location that connects to the public sewer system in the event that a unique sampling location in the end compartment of a grease interceptor (GI) is not available or there is no external GI.
(2) The village also reserves the right to apply the FSE Local Limit to the wastewater in the next sanitary sewer manhole downstream of the facility in the event that there is neither a GI sampling location nor a sampling manhole at the site.
(B) Toxic pollutants. No user shall discharge any wastewater containing concentrations greater than the daily maximum local limits as set forth below into any sewers that connect either directly or indirectly to the POTW.
POLLUTANT (total unless otherwise listed) | CONCENTRATION (mg/l) | |
Daily Maximum | Instantaneous Maximum | |
POLLUTANT (total unless otherwise listed) | CONCENTRATION (mg/l) | |
Daily Maximum | Instantaneous Maximum | |
Arsenic | 1.0 | |
Cadmium | 0.4 | |
Chromium | 5.0 | |
Chromium (hexavalent) | 1.2 | |
Copper | 1.1 | |
Cyanide | 0.3 | |
Lead | 0.7 | |
Mercury (see § 13-6-4) | 0.0005 | |
Nickel | 0.9 | |
Silver | 0.5 | |
Zinc | 1.4 | |
(C) The village will apply the local limits found in divisions (A) and (B) of this section normally at the end-of-pipe point where the non-residential waste is discharged to the municipal sewer system.
(D) The village reserves the right to establish requirements, by ordinance or in a wastewater discharge permit or general permit, the quantities and rates of discharge from any user.
(E) The village reserves the right to establish, by ordinance or in a wastewater discharge permit, mass limitations rather than concentration limitations on discharges particularly if users are using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate.
(F) The village reserves the right to set specific limits for those pollutants not identified in divisions (A) or (B) of this section on a case by case basis for impacts caused to the POTW including but not limited to interference, potential problems, pass through and prevention of beneficial bio-solids re-use. Those limits shall be set forth in a wastewater discharge permit per Article 9.
(1) Local limits for additional pollutants not identified in divisions (A) or (B) of this section will be noticed to the permit holder a minimum of 30 days prior to the effective date of the wastewater discharge permit. In the event that the village receives written comment on said limit during the comment period, the limit will take effect within 60 days of the public notice date to allow review and comment by the village.
(G) The village may develop best management practices (BMPs), by ordinance or in individual wastewater discharge permits or general permits, to implement local limits and the requirements of § 13-6-2.
(H) Any user whose discharge may be pretreated and/or treated more effectively by the village and discharges to the village's POTW that cause the village to alter its method of wastewater treatment or bio-solids disposal to a more costly method shall be assessed the differential cost between the more costly method of treatment and the less costly method of treatment. Such costs shall only be assessed upon approval of the Village Board.
