NOTIFICATION OF ALTERATION OR DEMOLITION OF POSSIBLE LANDMARK.

(a) A state agency may not alter, renovate, or demolish a building possessed by the state that was constructed at least 50 years before the alteration, renovation, or demolition and that has not been designated a landmark by the committee, without notifying the committee of the proposed alteration, renovation, or demolition not later than the 60th day before the day on which the agency begins the alteration, renovation, or demolition.

(b) After receipt of the notice the committee may waive the waiting period; however, if the committee institutes proceedings to determine whether the building is a state archeological landmark under Section 191.092 of this code not later than the 60th day after the day on which the notice is received by the committee, the agency must obtain a permit from the committee before beginning an alteration, renovation, or demolition of the building during the time that the committee's proceedings are pending.

(c) Should the committee fail to provide a substantive response within 60 days to a request for a review of project plans, application for permit, draft report review, or other business required under the Antiquities Code, the applicant may proceed without further reference to the committee.
