Wastewater Treatment Works Compliance Maintenance Program

The Compliance Maintenance Annual Report (CMAR)

Chapter NR 208, Wis. Adm. Code (PDF, exit DNR) is more commonly known as the Compliance Maintenance Annual Report (CMAR) rule for publicly and privately owned domestic wastewater treatment works. The CMAR is a self-evaluation tool that promotes the owner's awareness and responsibility for wastewater collection and treatment needs, measures the performance of a wastewater treatment works during a calendar year, and assesses its level of compliance with permit requirements.

CMAR requirements have been in existence since 1987. Revisions to Chapter NR 208, Wis. Adm. Code, became effective January 2005, and January 2006 for satellite collection systems.
