Explanatory statement—2021 c 65: See note following RCW 53.54.030.

Short title—2019 c 292: See RCW 70A.350.900.

Finding—Intent—2013 c 69: "(1) The legislature finds that it is critically important that scientific information used to inform public policy be of the highest quality and integrity. Furthermore, the legislature recognizes that a public benefit is derived from greater transparency as to what scientific information, data, or records are being used to inform public policy or relied upon in agency decision making.

(2) Therefore, in order to help ensure that agencies routinely use scientifically credible information in conducting their policy-making functions, it is the intent of the legislature to have those sources of scientific information reviewed and relied upon by agencies be identified in a clear and transparent way."
