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. They anticipate finalizing the draft manual by March 29, 2013 and making it available 

to design engineers across the state for utilization and consideration in submitting permit to install

or construction applications. In finalizing this manual, Ohio EPA will take into consideration any 

comments or opinions submitted. To discuss any comments, please contact the following: 

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