INDUSTRIAL PRETREATMENT PROGRAM “Compliance Through Cooperation” Industrial Pretreatment Program

The Manatee County Utilities Department Wastewater Compliance Division is responsible for administering regulations affecting commercial establishments discharging wastewater into Manatee County’s Sanitary Sewer Collection System. Regulations are designed to prevent businesses from discharging substances that can degrade the publicly owned treatment works (POTW), harm workers, or negatively impact the environment.

The National Pretreatment Program is a cooperative effort of federal, state, and local regulatory agencies established to protect water quality.  The program is specifically designed to reduce the level of pollutants discharged by industry and other non-domestic wastewater sources into municipal sewer systems, and thereby reduce the amount of pollutants released into the environment from these sources.   Authority to administer Manatee County’s Industrial Pretreatment Program is established by the United States Environmental Protection Agency (USEPA) in Title 40 Code of the Federal Regulations (CFR), Chapter 1, Subchapter N, Part 403 ; by the Florida Department of Environmental Protection in Chapter 62-625 of the Florida Administrative Code (F.A.C.); and Manatee County’s most current Sewer Use Ordinance.


Affected Operations

All businesses, including industrial, commercial, and governmental facilities that discharge anything other than normal domestic wastewater are subject to the requirements of the Sewer Use Ordinance.   For most businesses, this simply means abiding by the prohibited discharge standards found in Manatee County's most current Sewer Use Ordinance.


Some businesses, determined to be Significant Industrial Users (SIU), may be subject to additional requirements including implementation of a pretreatment system.   The following operations are designated as SIU:

  • Businesses engaged in operations identified as “categorical” processes as defined in 40 CFR Part 403, 62-625.410 F.A.C.
  • Businesses or operations (including groundwater remediation operations) that discharge 25,000 gallons per day or more of process wastewater (excluding sanitary, noncontact cooling and boiler blowdown wastewater) or contribute a discharge waste stream which makes up 5 percent or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant.
  • Businesses whose discharge has a reasonable potential to adversely affect the POTW’s operation or for violating any pretreatment standard.'


Application Process

Any business that is designated as a Significant Industrial User must complete an Industrial User Discharge Permit Application.  A Permit Application Manual is provided as a guide through the permitting process.   If a business is unsure as to whether it is a Significant Industrial User, it should contact the office of the Wastewater Compliance Division.


While enforcement is a primary responsibility of the Industrial Pretreatment Program, it is not the sole objective.   Wastewater Compliance Division staff is committed to working with and educating local businesses to achieve pollution prevention, waste reduction, and water reuse.
