The bill amends RCW 43.21B.110 to expand the jurisdiction of the pollution control hearings board to include appeals related to civil enforcement decisions made by the Department of Natural Resources under RCW 76.04.205. This addition allows for a more comprehensive review process of decisions made by the Department of Natural Resources, thereby enhancing accountability and oversight in environmental enforcement matters.

In addition to the new insertion regarding the Department of Natural Resources, the bill also clarifies the types of decisions that the hearings board will not conduct hearings for, including those required by law to be handled by the shorelines hearings board and specific departmental hearings. This delineation aims to streamline the appeals process and ensure that cases are directed to the appropriate forums for resolution.
