The Superintendent is authorized to establish local limits pursuant to 40 CFR 403.5(c).
(a) Local Limits. No discharger shall discharge wastewater containing pollutant quantities in excess of the limits enumerated in his, her or its industrial discharge permit as issued in accordance with Section 1043.04
.
(1) For industrial users, the local limits shall be derived from the Industrial Pretreatment Program Technical Limits Report prepared for the City of Geneva in November, 2008 and approved by the OEPA on February 17, 2009.
(2) The total available mass limitations for incoming industrial waste at the Geneva Wastewater Treatment Plant shall be as follows:
CHART #1 | |
Parameter | Available Industrial Mass Limit Daily Maximum lbs/day |
CHART #1 | |
Parameter | Available Industrial Mass Limit Daily Maximum lbs/day |
Cadmium | 0.006 |
Chromium | 1.569 |
Copper | 0.118 |
Lead | 0.095 |
Mercury | -1.0017 |
Nickel | 0.648 |
Zinc | 0.253 |
The Wastewater Superintendent, shall have the authority to allocate the loadings for each industrial user in applying the total available mass limitations (as shown above). | |
(b) The following pollutant limits are established to protect against pass through and interference. No person shall discharge wastewater containing in excess of the following:
CHART #2 | |
Parameter | Uniform Concentration Limit Daily Maximum mg/L |
CHART #2 | |
Parameter | Uniform Concentration Limit Daily Maximum mg/L |
Cadmium | 0.037 |
Chromium | 9.404 |
Copper | 0.707 |
Lead | 0.57 |
Mercury | BMP |
Nickel | 3.885 |
Zinc | 1.515 |
The uniform concentration limits shown above were derived from Chart #1 using a total industrial flow of 0.020 million gallons per day. | |
(1) BMP: Best Management Practices as defined in Section 1043.014(e).
(2) The above limits apply at the point where the wastewater is discharged to the POTW. All concentrations for metallic substances are for total metal unless indicated otherwise. The Superintendent may impose mass limitations in addition to the concentration-based limitations above.
(c) The Superintendent 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 Section 1043.021.
