City of Saginaw, Michigan

The Industrial Pretreatment Program (IPP) is mandated by the Environmental Protection Agency (EPA). The program requires the City of Saginaw to regulate the wastewater, stormwater, and discharges from industries into the City of Saginaw's collection system. As a result, the amount of pollutants released into the Saginaw Bay Watershed is reduced.

The purpose of the program is to:

  • Protect the City's Publically Owned Treatment Works (POTW)
  • Protect the collection systems
  • Protect the health and safety of the POTW workers
  • Prevent pollutant interference at the Wastewater Treatment Plant (WWTP) and pollutant pass through to the Saginaw River
  • Prevent noncompliance of the City's National Pollutant Discharge Elimination System (NPDES) Permit
  • Protect the Saginaw River

The IPP is staffed by an administrator and two Environmental Compliance Analysts working Monday through Friday from 8:00 am to 4:30pm. Occasionally emergencies arise and weekend and night work is required of the personnel.

To administer the program, the Environmental Compliance Office issues permits for wastewater discharges, inspects industries regularly and samples wastewater discharges. They also handle complaints and compliance issues with regards to federal, state and local discharge regulations.

Permits are issued to industries based on their wastewater characteristics or volume of discharge. The permits require the industries to monitor for pollutants of concern such as Polychlorinated Biphenyls (PCBs), Lead, Mercury, Oils and Grease or others. Permitted Industrial Users are required to sample, test their discharges, and submit compliance reports to the City of Saginaw.

Permitted Industrial User types include the following:

  • Categorical Industrial Users (CIUs) must comply with federal categorical standards as listed in the Code of Federal Regulations, 40 CFR 403.
  • Significant Industrial Users (SIUs) are regulated based on process flow, POTW loading, pollutants of concern, or as deemed necessary by the Control Authority (City of Saginaw) as defined in the Code of Federal Regulations 40 CFR 403.
