Board of Environmental Quality

The Board of Environmental Quality is a rulemaking and advisory body created by the Environmental Protection and Health Act (Idaho Code § 39-107). The Board consists of seven members appointed by the governor to serve 4-year terms.

Powers and Authorities

Rulemaking proceedings and hearings of the Board are governed by the Idaho Administrative Procedure Act (Idaho Code § 67-52).

DEQ is responsible for drafting proposed and temporary rules for consideration by the Board, and Board determinations may be petitioned for judicial review.

Anyone aggrieved by the action or inaction of the department may request a hearing by the Board or a Board-designated hearing officer.

Meet the Members

Members must be citizens of the United States, residents of the state of Idaho, and qualified voters. Appointments must ensure appropriate geographic representation of the state of Idaho. No more than four members may be from any one political party. Two members are chosen for knowledge and interest in solid waste, air quality, and water quality, and one for air, water, and solid waste issues.

Each year, the Board elects a chair, vice chair, and secretary. Five members are necessary for a quorum at any regular or special meeting. The action of the majority of members present constitutes the action of the Board.

Members are paid for their travel and other expenses, plus $50 per day during session and while traveling to and from meetings as provided by Idaho Code § 59-509(h).
