(b) The executive summary and the annual report are public records. On request, the person shall make available to the public a copy of the executive summary or annual report.

(c) If an owner or operator of a facility for which a source reduction and waste minimization plan has been prepared shows to the satisfaction of the commission that an executive summary, annual report, or portion of a summary or report prepared under this subchapter would divulge a trade secret if made public, the commission shall classify as confidential the summary, report, or portion of the summary or report.
(d) To the extent that a plan, executive summary, annual report, or portion of a plan, summary, or annual report would otherwise qualify as a trade secret, an action by the commission or an employee of the commission does not affect its status as a trade secret.
(e) Information classified by the commission as confidential under this section is not a public record for purposes of Chapter 552, Government Code, and may not be used in a public hearing or disclosed to a person outside the commission unless a court decides that the information is necessary for the determination of an issue being decided at the public hearing.
