Project Description:

DEC received an application from the permittee to modify the existing State Pollutant Discharge Elimination System(SPDES) permit. A total residual chlorine limit was requested by the permittee in order to use sodium hypochlorite for microbial control in the paper making process at the facility.

  • Added a new daily average settleable solids limit of 0.2 mL/L.
  • Added a new daily maximum temperature limit of 103 °F.
  • Added a new daily maximum total residual chlorine limit of 94 µg/L and 1.2 lbs/day.
  • Added new total aluminum limits:
    • Daily Average: 2000 µg/L and 25 lbs/day.
    • Daily Maximum: 4000 µg/L and 50 lbs/day.
  • Updated Whole Effluent Toxicity (WET) testing action levels to 2.9 TUa and 19 T Uc, and revised the WET testing schedule.
  • Required reporting of both mass and concentrations for monitored parameters.
  • Removed the Schedule of Compliance, as the requirements have been completed.
  • Added a Schedule of Submittals requiring a thermal discharge study.
  • Added a General Requirements section.

Please note that when the Department updates a permit this typically includes updated forms incorporating the latest general conditions.
