Each public corporation formed under this chapter shall be governed by a board of directors. All powers of the corporation shall be exercised by the board or pursuant to its authorization. The initial board shall consist of three directors appointed by the Governor from among the persons who filed the application to incorporate. The Governor shall appoint the directors as soon as may be practicable after he is notified, as required in Section 9-6-5, that the public corporation has been formed. The terms of the directors shall be staggered, the first term of one director being for three years from and after the date of his appointment, the first term of another director being for six years from and after the date of his appointment and the first term of the remaining director being for nine years from and after the date of his appointment; thereafter the term of office of each director shall be for nine years. Vacancies on the board shall be filled by appointment by the Governor. Appointments to fill vacancies which occur during a regular term shall be for the unexpired term. Each director appointed by the Governor shall be a person of good moral character, and he shall be a qualified elector of this state. Directors shall be eligible for reappointment. If the certificate of incorporation shall so provide, each director may be reimbursed by the authority for actual expenses incurred by him in and about the performance of his duties; and, in addition thereto, each director may be further compensated by the authority in an amount not to exceed $1,200.00 per year, as shall be determined by the board of directors. Any director of the authority may be impeached and removed from office in the same manner and on the same grounds provided by Section 175 of the Constitution of Alabama and the general laws of the state for impeachment and removal from office of the officers mentioned in said Section 175.
