Multi-State Regulation and Policy Survey of Onsite Wastewater Treatment System Upgrade Programs

Michael A. Mezzacapo
September 2019, xi + 84 pp.


This report was commissioned by the Cesspool Conversion Working Group (CCWG) to evaluate and analyze cesspool and conventional on-site wastewater treatment system (OWTS) conversion methods in other states. States were chosen based upon proximity to a coastal environment, the number of cesspools, and recent legislation. Six states were evaluated based upon criteria approved by the Data and Prioritization Subgroup of the CCWG. This document briefly summarizes other state efforts, policies, and procedures regarding OWTS upgrades and not meant to be an exhaustive report on state OWTS regulations. The document is organized by state and subdivided into eight categories: (1) regulation overview, (2) regulation enforcement and requirements, (3) methods to determine priority conversion areas, (4) methods to identify impaired waters, (5) nutrient reduction science, (6) conversion technologies/future approval, (7) conversion method and timelines, and (8) funding mechanisms.
