Adding the department of natural resources' civil enforcement decisions under RCW 76.04.205 to appeals that may be heard by the pollution control hearings board.

HB 1646 adds the Department of Natural Resources' (DNR) civil enforcement decisions under RCW 76.04.205 to the list of cases that can be appealed to the Pollution Control Hearings Board. This change directly affects individuals or businesses facing DNR enforcement actions related to natural resource management. The bill explicitly expands the board's jurisdiction to include these specific DNR decisions, which were previously not covered under the board's authority. This adjustment streamlines appeals for these cases by directing them to a single established forum instead of other potential review channels.
