What is the Revised Total Coliform Rule (RTCR)?
U.S. EPA issued a rule that changes the monitoring requirements for total coliform bacteria and the way that public water systems (PWSs) must respond when samples show that total coliform bacteria (TC) are present. Ohio EPA was required to adopt the new requirements, which went into effect on April 1, 2016. The changes affect all public water systems.
The sections below include required forms, summaries of key requirements, other helpful documents and answers to frequently asked questions. A fact sheet outlining some key changes for labs is also available.

Do you own or operate a seasonal public water system? Depressurized and partially-depressurized seasonal public water systems are required to complete a start-up procedure before they open every year.
