What is Primacy?

Frequently Asked Questions

Wyoming is the only State that does not administer the public water system activation, drinking water monitoring, consumer confidence report, sanitary survey, and laboratory certification programs of the Safe Drinking Water Act. The EPA Region 8 Office out of Denver, Colorado implements these programs in the State of Wyoming. EPA Region 8 has primary enforcement authority, or "primacy", for all Safe Drinking Water Act regulatory programs except the Operator Certification and Capacity Development Programs. Wyoming also implements the Source Water Assessment and Protection, although it is not considered a regulatory program, and is therefore not a “primacy” program.
