Operator Assistance

The Operator Assistance Group within Wastewater Compliance provides operation and laboratory technical assistance to wastewater treatment plant (WWTP) operators and facilities. The objective of the 104-g-1 Technical Assistance Program is to assist small community wastewater treatment plants (less than 5.0 MGD) with NPDES compliance.

Our technical staff provides on-site, hands-on assistance in the proper operation of wastewater plants. Also, the technical staff provides management assistance and promotes the involvement of community elected officials in the operation of wastewater treatment plants. For more information, contact IDEM's Office of Water Quality, by phone, at (317) 232-8488, or via email at info@idem.in.gov.

Laboratory Assistance

Laboratory technical assistance with NPDES approved test methods or other laboratory issues is available. The DMRQA Laboratory Quality Assurance Program is administered by the Office of Water Quality Compliance Branch. All major dischargers must participate annually in a DMRQA study. Minor dischargers must participate on a three-year rotating schedule. Information is distributed by U.S. EPA each year in January or February. The rotating schedule for minors is:

  • 2016:
    • Industrial NPDES (including some water treatment plants (WTPs)) Permit holders
    • Industrial Pretreatment Permit holders
  • 2017:
    • Municipal WWTPs
    • Municipal WTPs with an NPDES discharge
  • 2018:
    • Semi-publics (such as schools, campgrounds, and mobile home parks)
    • State and federal facilities (including rest areas and state parks)
