If the proposed discharge exceeds the following concentration criteria, the <br />user shall submit a completed Permit Application to the Industrial Pretreatment Section. <br />These concentrations apply at the point where the wastewater is discharged to the <br />POTW collection system. The City reserves the right to modify, add or delete Protection <br />Criteria as the City deems necessary: <br /> <br />Parameter mg/l <br />Arsenic (total) 0.001 <br />Cadmium (total) 0.0002 <br />Chromium (total) 0.002 <br />Copper (total) 0.034 <br />Cyanide (total) 0.003 <br />Lead (total) 0.003 <br />Mercury (total) 0. 00007 <br />Molybdenum (total) 0.0009 <br />Nickel (total) 0.003 <br />Selenium (total) 0.0005 <br />Silver (total) 0.0003 <br />Zinc (total) 0.139 <br />Biochemical Oxygen Demand 300 <br />Total Suspended Solids 300 <br />HEM (total) 50 <br />D.

These Local <br />Pollutant Allocations are also based on the Maximum Allowable Headworks Loadings, <br />Pass-Through, Interference, or protection of health and are implemented through the <br />issuance of a industrial wastewater discharge permits or other control mechanisms. A <br />Local Pollutant Allocation is not a local limit, it is an industry specific limit for a pollutant <br />that is not included with the local limits or Categorical Pretreatment Standards but still <br />have the potential to adversely affect the plant or collections system and therefore <br />must be monitored. <br />These limits apply at the point where the wastewater is discharged to the POTW (end of <br />the pipe). <br />E. Best Management Practices <br />The Director may develop Best Management Practices (BMPs), for inclus ion in an <br />ordinance or in individual wastewater discharge permits, to implement Local Limits and <br />the requirements of Section 2.1.
