Tex. Health and Safety Code § 12.016

(a) Any statements, correspondence, or other form of oral or written communication made by a member of the legislature to a department official or employee during a public hearing conducted by the department shall become part of the record of the hearing, regardless of whether the member is a party to the hearing.

(b) When a public hearing conducted by the department is required by law to be conducted at a certain location, the department shall determine the place within that location at which the hearing will be conducted. In making that determination, the department shall consider the cost of available facilities and the adequacy of a facility to accommodate the type of hearing and anticipated attendance.

(c) The department shall conduct at least one session of a public hearing after normal business hours on request by a party to the hearing or any person who desires to attend the hearing.

(d) An applicant for a license, permit, registration, or similar form of permission required by law to be obtained from the department may not amend the application after the 31st day before the date on which a public hearing on the application is scheduled to begin. If an amendment of an application would be necessary within that period, the applicant shall resubmit the application to the department and must again comply with notice requirements and any other requirements of law or department rule as though the application were originally submitted to the department on that date.

(e) If an application for a license, permit, registration, or similar form of permission required by law is pending before the department at the time when changes take effect concerning notice requirements imposed by law for that type of application, the applicant must comply with the new notice requirements.
