Subject of Possible Rule Making: Chapter 246-390 WAC, the state board of health (SBOH) is considering amendments to the drinking water laboratory certification and data reporting rules (lab rule) to align laboratory data reporting requirements with the anticipated changes to chapter 246-290 WAC, Group A public water supplies (Group A rule) as related to per- and polyfluoroalkyl substances (PFAS).

Reasons Why Rules on this Subject may be Needed and What They Might Accomplish: SBOH is considering amendments to the Group A rule that may necessitate changes to the lab rule. SBOH is considering including a new PFAS template for the purposes of data reporting, adding a requirement for notification when PFAS sample results exceed a state action level, and adding state detection reporting limits for PFAS. The rule revision may also include technical and clarifying corrections as needed.

Other Federal and State Agencies that Regulate this Subject and the Process Coordinating the Rule with These Agencies: The Washington department of health (department) and SBOH will coordinate the rule making with the Washington department of ecology (ecology) in developing consistent regulations. The department and ecology jointly administer the state's cooperative laboratory certification program.

Interested parties can participate in the decision to adopt the new rule and formulation of the proposed rule before publication by contacting Jocelyn W. Jones, P.O.
