The Gorge Commission has its own rules for open meetings, public records, financial disclosure, conflicts of interest, public contracts, and how it makes decisions. These rules must follow the stricter laws from either Oregon or Washington.

After each legislative session, the Commission reviews its rules to make sure they still meet this requirement. It also has special rules for appeals, enforcement, and other regular duties.

The Gorge Commission files its rules with both the Oregon Secretary of State and the Washington Code Reviser. These rules are not technically part of the Oregon Administrative Rules (OAR) or the Washington Administrative Code (WAC) because the Gorge Commission is not a state agency. The official Gorge Commission rules are listed below. Oregon does include Gorge Commission rules in its printed and online versions of the OAR compilation. Washington does not include them in the WAC.
