Sample Port and Collection Location <br /> <br />1. Sample site 260 is located after the final pH tank in an open top weir box with V-notch overflow. <br />Composite samples are collected in the final discharge tank after the weir box, and grab samples <br />are collected from the overflow after the V-notch weir. The discharge at this point is strictly <br />process wastewater which has been treated <br /> <br />2. Any discharge of water or waste having a pH lower than 6.0 S.U. or a pH higher than 11.0 S.U. is <br />prohibited. In addition, the permittee’s wastewater discharge shall not exceed the following effluent <br />limitations: <br /> <br /> Effluent limitations for Sample Site Outfall # 260: <br />Parameter Daily Maximum Limit (mg/L) Monthly Average Limit (mg/L) <br />Arsenic (mg/L) *Report *Report <br />Cadmium (mg/L) *Report *Report <br />Chromium (mg/L) 2.77 1.71 <br />Copper (mg/L) 3.38 0.8 <br />Cyanide (mg/L) 1.2 0.65 <br />Lead (mg/L) *Report *Report <br />Mercury (mg/L) 0.00019 NA <br />Nickel (mg/L) 3.98 0.8 <br />Oil & Grease (mg/L) 300 NA <br />Oil & Grease, TPH (mg/L) 100 NA <br />Silver (mg/L) *Report *Report <br />TTO (mg/L) 2.13 NA <br />Zinc (mg/L) 2.61 1.48 <br /> <br />*Note: In accordance with the City of South Bend’s “What You Need Is What You Get” allocation method, local <br />Daily Maximum and Monthly Average limits have only been developed for those pollutants that have been <br />observed at or above certain concentrations in each Significant Industrial User’s wastewater discharge. If <br />“Report” appears on the table, it has been determined that an allocation of this pollutant is not necessary. The <br />permittee shall compare any monitoring data for these pollutants with the screening table in Part I (3) below. If
