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:

Permit-to-Install Requirements for Sanitary Sewer Projects
Make sure the detailed plans include:
For other related topics: OAC 3745-42
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.
Interim Onsite Sewage Treatment System Guidance Document
Listing of SFOSTS (as of 10/17/07) - On January 1, 2007, Ohio Department of Health's rules for Small Flow Onsite Sewage Treatment Systems went into effect. Please visit the link below for a list of counties that have or will take on the SFOSTS: http://www.odh.ohio.gov/odhprograms/eh/sewage/STSpages/sfosts1.aspx. You can also view the following map.
Forms associated with onsite system projects.
For other related topics: OAC 3745-42
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.
A PTI for a holding tank must also include:
Wastewater treatment plants are broken up into two main distinctions, >100,000 gpd and <100,000 gpd.
For plants >100,000 gpd see 10 State Standards
For plants <100,000 gpd see the Green Book.
In addition to wastewater treatment plant requirements listed here, applicant must provide all material included in the How to Obtain a PTI tab.
Forms associated with discharging system projects.
