§ 52.067  LOCAL LIMITS.
   (A)   The following pollutant limits are established to protect against pass through and interference.  No person shall discharge wastewater containing in excess of the following instantaneous maximum allowable discharge limits:
      (1)   0.34 mg/l arsenic.
      (2)   0.54 mg/l cadmium.
      (3)   2.77 mg/l chromium.
      (4)   3.38 mg/l copper.
      (5)   1.2 mg/l cyanide.
      (6)   0.69 mg/l lead.
      (7)   0.26 mg/l mercury.
      (8)   3.98 mg/l nickel.
      (9)   0.43 mg/l silver.
      (10)   2.61 mg/l zinc.
      (11)   1.71 mg/l selenium.
      (12)   2.28 mg/l molybdenum.
   (B)   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, or in place of, the concentration-based limitations above.
   (C)   No person shall discharge wastewater containing  concentrations of molybdenum that in combination with other contributors shall exceed the calculated maximum allowable mass headworks loading of that pollutant for the Claremore Wastewater Treatment Plant.  The city in issuing wastewater discharge permits shall allocate a concentration limit for molybdenum to each significant industrial user which is discharging molybdenum in excess of domestic concentration limits.  In allocating said concentration limits the city shall use its best practical judgment.  Concentration limits apply at the point where the industrial waste is discharged to the POTW.
