Wastewater Permit-to-Install (PTI) Program

picture of water pipe

A PTI is needed when a person wishes to construct any wastewater collection, storage or treatment system or wishes to modify any existing wastewater collection, storage or treatment system.

A PTI is required by Ohio Revised Code 6111.44 and Ohio Revised Code 6111.45 and rules in Ohio Administrative Code 3745-42.

  • New Fact Sheet - RVs and Manufactured Homes as "Temporary Dwellings" - look under "Water" tab
  • Greenbook Update - The Ohio Environmental Protection Agency – Division of Surface Water has developed a final draft of the document entitled Design Standards: Wastewater Treatment Plants & Collection Systems ≤ 100,000 gpd.  This document is an update to the technical design manual previously referenced to as “Sewage:  Collection, Treatment and Disposal Where Public Sewers Are Not Available” or otherwise known as the Greenbook.  This updated design manual is the compilation of years of research and meetings with experienced Ohio EPA staff and networking with design engineers in the field and reflects a representation of what has been learned through the oversight of the operations and maintenance of these smaller wastewater treatment plants (less than or equal to 100,000 gallons per day capacity).  The draft manual not only defines typical design parameters for these wastewater treatment plants, but also highlights operating conditions that may be appropriate to be considered.  Experience dictates that operational flexibility addressing variables are very important in consideration of the design, construction and operation of a small wastewater treatment plant.  Though the standards established within this design manual are not regulations or requirements, the standards expressed are a starting point and highlights Ohio EPA’s expressed opinion as to proper design considerations.

    The PTI Oversight Committee (an internal divisional work group) was responsible for revising the Greenbook.  In finalizing this manual, Ohio EPA took into consideration any comments or opinions which were submitted.  To discuss any comments, please contact the following:

    Jon van Dommelen (Technical Lead) (614) 644-2011 or jon.vandommelen@epa.ohio.gov


  • Ohio Administrative Code (OAC) Rule 3745-42-02, Applicability, Exemptions and Procedures is out for Early Stakeholder Outreach.  For more information please see the Factsheet located at  http://epa.ohio.gov/dsw/dswrules.aspx.

Once you determine you need a PTI for your project, the following is a step-by-step process of “How to Obtain a PTI.”  If you are not sure that you need a PTI, please contact a Central Office staff member.

An application cannot be considered complete unless all applicable questions are answered and the required information submitted. Please make sure you have the most recent version when you prepare your application.

  1. Fill out Form A. (Please note: Applicant needs to sign form. This is not the design engineer or consultant.)
  2. Determine and complete appropriate B Forms, dependent upon if the project is a Sanitary Sewer Extension, Onsite System, Holding Tank, or Wastewater Treatment Plant.
  3. Fill out an Antidegradation Addendum form for all PTI projects that meet the applicability criteria established under Ohio Administrative Code 3745-1-05(B)(1).  For sanitary sewer extensions with stream crossings, and for WWTP construction if there is work in or near a stream bed, also fill out a Stream Evaluation Addendum and worksheet.
  4. Submit the following to the appropriate District Office.
  • four (4) copies of detailed plans with PE stamp, signature and date;
  • at least two (2) copies of any separate equipment/construction specifications with PE stamp, signature and date. If the engineer wants an approved copy, submit three copies. The pages of the specifications, if separate from the plans, must be bound together as a separate document with a cover page with the same project title/name as the plans. For smaller projects, the engineer is encouraged to include the specifications on the detailed plans.
  • two (2) copies of Form A;
  • two (2) copies of the corresponding Form B;
  • two (2) copies of the Antidegradation Addendum Form if the project is subject to the Antidegradation Rule (OAC 3745-1-05). See item 19 on application Form A.
  • two (2) copies of the Stream Evaluation Addendum and Worksheet, if appropriate, e.g. project involves work near a stream or there are stream crossings
  • appropriate fees
    • (a) $100 Application Fee
    • (b) $100 Plan Review Fee
    • (c) Construction/Installation Cost multiplied by 0.0065

Total Fee = (a) + (b) + (c)  (Not to exceed $15,100.00)

For specific requirements please see the Sanitary Sewer Extensions, Onsite Systems, Holding Tanks, or Waste Water Treatment Plants tabs.

Each application form is available online as an Adobe Reader [PDF] file and a Microsoft Word [DOC] file. The PDF forms must be printed and completed by typewriter or by hand. The [DOC] forms can be completed by using your keyboard to type in the appropriate language or to make the appropriate selections. If the text of the [DOC] form jumps around while you're typing, switch to Normal View (under View on the Word toolbar or in the lower left hand corner of your screen).

onsite sewage treatment picture

Onsite sewage treatment & dispersal systems are installed in areas where sanitary sewers are not available. The goal of these systems is the treatment of wastewater via mechanical and/or natural processes to the point where the treated wastewater can be safely released into the environment without causing harm to the surrounding environment and human health.

In addition to the specific onsite sewage treatment & dispersal system requirements listed here, applicant must provide all material included in the How to Obtain a Permit tab.

Holding tanks for sewage are permissible when no sanitary sewers are readily available, when sanitary sewers are being proposed but will not be available for up to 12 months, or when an existing onsite wastewater treatment & dispersal system has failed and sewers are not available. Holding tanks for industrial wastewater are generally acceptable with proper permits and construction.

In addition to specific holding tank requirements listed here, applicant must provide all material included in the How to Obtain a PTI tab.

Semipublic Disposal System Inspection (HB110) Program

By implementing House Bill 110 (HB110) in 1984, the Ohio General Assembly created Ohio EPA's Semipublic Disposal System Inspection program (often referred to as the HB110 program). The program is a contractual partnership between local health districts (LHDs) and Ohio EPA, whereby LHDs conduct, on behalf of the Agency, inspection and enforcement services for commercial sanitary waste treatment/disposal systems discharging between 0-25,000 gallons per day (semipublics).
