NEW Water's Industrial Pretreatment Program regulates certain industries defined as Significant Industrial Users (SIUs) in order to control the introduction of pollutants into the sewerage system and, ultimately, its treatment facility. These SIUs must comply with federal, state, and local requirements through the use of a permit system. An Industrial Wastewater Discharge Permit outlines and references the requirements necessary to comply with all applicable wastewater regulations.
According to NR 211.03 (19m), Significant Industrial Users (SIU) are defined as the following:
(a) Any industrial user subject to the categorical pretreatment standards in chapters NR 221 to 297;
(b) Any industrial user which discharges an average of 25,000 gallons per day or more of wastewater to the POTW, excluding sanitary, noncontract cooling and boiler blowdown wastewater;
(c) Any industrial user that discharges to the POTW a process waste stream which makes up 5% or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant:
(d) Any centralized waste treater; or
(e) Any other industrial user designated as a significant industrial user by the control authority.
Periodic Compliance Reports Due: July 15 and January 15 of each year
pH Variance Data Due: the 15th of every month
pH Variance Cleaning & Televising Due: once every 3 years
Permit Renewal Application Due: July 4, every 5 years
NEW Water has implemented a new pretreatment program element called the Industrial Achievement Awards, which gives recognition to Significant Industrial Users (SIU) that demonstrate exceptional pretreatment performance.
The awards will be given at three different levels for each consecutive year of meeting established requirements. Those levels are as follows:
Silver Award: Meet the below requirements for the previous regulatory year.
Gold Award: Meet the below requirements for three consecutive years.
Platinum Award: Meet the below requirements for five consecutive years.
SIUs are evaluated with the following criteria:
The pH criteria are as follows:
Each year after receipt of the Periodic Compliance Reports in January, recipients will be determined by the Pretreatment Coordinator. If the SIU satisfies all of the requirements, the SIU will be placed into the appropriate award category according to the number of successful years.
The award recipients will be announced annually at the March Commission meeting. Award recipients will receive a certificate in honor of their achievement. An ad will be purchased in the Green Bay Press-Gazette publishing each year's winners. Each year's winners will also be displayed on NEW Water's website and included in the external quarterly newsletter.
