Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The proposed rule updates the publication date of federal rules adopted by reference under 40 C.F.R. Part 61 from 2025 to the most recently adopted 2026 version in WAC 246-247-035. The proposed amendment makes no changes to any requirements previously adopted, but the department must adopt the annual updated publication date into state rule to receive full delegation of the radionuclide air emissions program from EPA.

Reasons Supporting Proposal: The intent of RCW 70A.388.040 is to safely regulate the possession and use of radioactive material within the state of Washington. The intent of RCW 70A.388.050(5) is to reduce redundant licensing requirements. The rule meets the intent of the statutes by adopting requirements as stringent as the federal requirements in order for the department to have full delegation authority from EPA.

Statutory Authority for Adoption: RCW 70A.388.040 and 70A.388.050(5).

Statute Being Implemented: RCW 70A.388.040 and 70A.388.050(5).

Rule is not necessitated by federal law, federal or state court decision.

Name of Proponent: Department of health, governmental.
