An Act relating to microplastic testing; and relating to a microplastic strategy plan.

HB 332 requires Alaska's Department of Environmental Conservation to develop and implement a statewide plan for regularly testing water, soil, fish, wildlife, and other environmental media for microplastics (defined as plastic particles under 5 millimeters). The department must use scientifically sound methods and update the testing schedule annually before July 1 in even-numbered years. This bill directly affects state environmental agencies by establishing mandatory testing protocols and reporting requirements for microplastic pollution. It does not alter existing public assistance programs, despite an unrelated amendment to health department duties appearing in the bill text.
