The Governor shall, by and with the advice and consent of the Senate, appoint three commissioners to the Interstate Environmental Commission created by the agreement or compact between the states of New York and New Jersey and Connecticut, each of whom shall be a resident voter of the State of New Jersey. The Commissioner of Environmental Protection and the Commissioner of Health and Senior Services shall serve as commissioners ex officio, and may designate a representative of their respective departments to represent them at all meetings, hearings and proceedings of the Interstate Environmental Commission with full power to vote and act on their respective behalf. In the event that either the Commissioner of Environmental Protection or the Commissioner of Health and Senior Services shall not qualify in accordance with the provisions of the compact, said commissioner shall designate a representative of his respective department to serve as an Interstate Environmental Commissioner until such time as the commissioner ex officio shall qualify.
Each appointive commissioner shall hold office, for a term of five years or until his successor has been appointed and qualified. At the expiration of the term of each appointive commissioner, the Governor shall, by and with the advice and consent of the Senate, appoint a successor who shall hold office for a term of five years or until his successor has been appointed and qualified. In the event of a vacancy occurring in the office of an appointive commissioner by death, resignation or otherwise, the Governor shall, by and with the advice and consent of the Senate, appoint his successor, who shall hold office for the unexpired term. Any commissioner may be removed upon charges and after hearing by the Governor. The commissioners shall have the powers and duties and be subject to the limitations provided for in the compact and agreement entered into between the signatory states and laws adopted by said states, and together with five commissioners from the states of New York and Connecticut shall form the Interstate Environmental Commission. The commissioners shall serve without compensation, but shall be paid their actual expenses incurred and incident to the performance of their duties.
