Environmental Hearings Office

The mission of the Environmental Hearings Office (EHO), which is comprised of two independent environmental boards, is to conduct fair and impartial hearings and issue clear and well-reasoned decisions, provide expeditious and efficient resolution of environmental appeals through hearings and alternative dispute resolution processes, foster a consistent statewide interpretation of Washington’s environmental laws in agency decision making and appeals, and assist parties in understanding the hearing process to ensure meaningful and enhanced access to justice. The website contains EHO decisions back to 1970, as well as sample forms for conducting an administrative appeal of an EHO decision.
