(a) After at least 10 days’ notice and a hearing, the commissioner may designate an area of the seacoast territory of this state as a catastrophe area if the commissioner determines, unless such a determination results in an adverse impact to the exposure of the association, that windstorm and hail insurance is not reasonably available to a substantial number of the owners of insurable property located in that territory because the territory is subject to unusually frequent and severe damage resulting from windstorms or hailstorms.
(b) The commissioner shall revoke a designation made under Subsection (a) if the commissioner determines, after at least 10 days’ notice and a hearing, that the applicable insurance coverage is no longer reasonably unavailable to a substantial number of owners of insurable property within the designated territory.

(c) If the association determines that windstorm and hail insurance is no longer reasonably unavailable to a substantial number of owners of insurable property in a territory designated as a catastrophe area, the association may request in writing that the commissioner revoke the designation. After at least 10 days’ notice and a hearing, but not later than the 30th day after the date of the hearing, the commissioner shall:
(1) approve the request and revoke the designation; or
(2) reject the request.
