The bill amends RCW 43.21B.110 to expand the jurisdiction of the pollution control hearings board to include appeals of civil enforcement decisions made by the Department of Natural Resources under RCW 76.04.205. This addition allows for greater oversight and accountability regarding environmental enforcement actions taken by the Department of Natural Resources, ensuring that affected parties have a clear avenue for appeal.

In addition to the new insertion regarding the Department of Natural Resources, the bill also reenacts and amends existing provisions related to the jurisdiction of the hearings board, specifying the types of decisions that can be appealed. The bill clarifies that certain hearings, such as those required by the shorelines hearings board or those conducted by the department for rule adoption, will not fall under the jurisdiction of the pollution control hearings board. This legislative change aims to streamline the appeals process while enhancing the board's role in environmental governance.
