Following is information about the various approval requirements for building or modifying wastewater treatment facilities, including sewer main extensions, lift stations, industrial or municipal wastewater treatment plants, and industrial or municipal pretreatment plants.
Existing permitted industrial wastewater treatment facilities (those with a valid NPDES permit) or existing industrial pretreatment facilities (but only those with permits issued by municipalities implementing U.S. EPA-approved industrial pretreatment ordinances) need not obtain a Wastewater Facility Construction Permit from IDEM prior to making modifications to their water pollution control equipment or wastewater treatment facilities. However, if modifications entail the installation of additional equipment for the treatment or control of any new influent pollutant or to increase treatment capacity, the facility must file a Notice of Installation and a design summary with IDEM within 30 days of the commencement of operation of the modified facility.
A permit is not required for modifications to repair, replace or add equipment at existing municipal or industrial water pollution control/wastewater treatment facilities, which are not associated with treating new types of influent pollutants or to increase the capacity of the facility.
In addition, under 327 Indiana Administrative Code (327 IAC 3-2-4(1-7)), a Wastewater Facility Construction Permit is not required for the following projects.
No fee is required for sewer projects or for state and federal projects. Meanwhile, governmental entities (county, municipal or township) and non-profit organizations are only required to pay $50 for new or expanded wastewater treatment facilities. All other applicants pay the following fees:

IDEM has 90 days to complete its review of a Wastewater Facility Construction Permit application. Sewer permits generally take 30 to 40 days, industrial pretreatment construction permits take 40 days, and treatment plant construction permits take 40-60 days. Meanwhile, applications for "as built" facilities initiate an enforcement action.
There is no public comment period required for a Wastewater Facility Construction Permit application. However, like all IDEM-issued environmental permits, it may be appealed by any affected or interested party. The appeal must be filed with the Office of Environmental Adjudication within 18 days (15 days, plus 3 days for mail delivery) of a permit decision.
Where IDEM’s Office of Water Quality issues a wastewater facility construction permit for the construction of sewer lines, a lift station, wastewater treatment facility, or other related equipment, construction must begin within one year of the date of issuance.
Change of ownership or property transfer may be processed at any time following the issuance of the permit.
Wastewater Facility Construction Permit applications are available at the IDEM OWQ permit application forms page.
