(1) does not have at the time of appointment the qualifications required for appointment to the board;
(2) does not maintain during service on the board the qualifications required for appointment to the board;
(3) violates a prohibition established by Section 552.004;
(4) cannot, because of illness or disability, discharge the member's duties for a substantial part of the member's term; or
(5) is absent from more than half of the regularly scheduled board meetings the member is eligible to attend during a calendar year, unless the absence is excused by majority vote of the board.
(b) If the executive director has knowledge that a potential ground for removal exists, the executive director shall notify the president of the board of the ground. The president shall then notify the governor that a potential ground for removal exists.
(c) The validity of an action of the board is not affected by the fact that the action is taken when a ground for removal of a board member exists.
