Industrial Waste Discharge Program

Press Enter to show all options, press Tab go to next option

The Industrial Waste Program's primary goals are the following:

  • Prevent the introduction of pollutants that can pass through, be incompatible or interfere with the operation of the Wastewater Treatment Facility (WWTF), including interference with sludge use or disposal.
  • Protect the WWTF, the collection system, and City operations/maintenance staff.
  • Improve opportunities to recycle or reclaim wastewater and sludge.

Federal, state and local regulations are enforced through permitting, monitoring and inspections of Significant Industrial Users (SIU). SIUs are defined in accordance with the Code of Federal Regulations 40 CFR 403.3 (t) as:

  • All industrial users subject to Categorical Pretreatment Standards, or
  • Any other user that has any one or more of the following characteristics:
    • An average discharge flow of equal to or greater than 25,000 gallons per day of process wastewater to the WWTF
    • Contributes a process wastestream which is 5 percent or more of the average dry weather hydraulic or organic capacity of the WWTF
    • Has a reasonable potential to adversely affect WWTF operations, or
    • Violates any pretreatment standard or requirement (in accordance with 40 CFR 403.8 (f) (6)).

Best Management Practices
In order to reduce the amount of pollutants reaching the San Lorenzo River, various creeks, and storm drains, and pollutants that pass through the wastewater treatment plant and progress on to Monterey Bay, the City has developed Best Management Practices (BMPs) for Industrial Facilities. The Municipal Code 16.19.100 requires that businesses comply with mandatory BMPs. Also, included with the mandatory BMPs, are recommended BMPs that are suggested as additional practices to prevent pollution.
