Ariz. Rev. Stat. § 28-7707 – Confidentiality and public disclosure

A. A proposer shall identify those portions of a proposal or other submission that the proposer considers to be trade secrets or confidential commercial, financial or proprietary information. In order for confidential and proprietary information and trade secrets to be exempt from disclosure, the private entity must do all of the following:
1. 1. Invoke exclusion on submission of the information or other materials for which protection is sought.
2. 2. Identify the data or other materials for which protection is sought with conspicuous labeling.
3. 3. State the reasons why protection is necessary.
4. 4. Fully comply with any applicable state law with respect to information that the proposer contends should be exempt from disclosure.
B. Each request for proposals issued pursuant to this chapter shall require each proposer to include with its proposal an executive summary covering the major elements of its proposal that do not address the proposer's price, financing plan or other confidential or proprietary information or trade secrets that the proposer intends to be exempt from disclosure. The executive summary shall be subject to release and disclosure to the public at any time. Notwithstanding any other law, in order to maximize competition under this chapter, no part of a proposal other than the executive summary shall be subject to release or disclosure by the department before an award of the public-private partnership contract and the conclusion of any protest or other challenge to the award, absent an administrative or judicial order requiring release or disclosure. After the award of the contract and the conclusion of any protest or other challenge to the award, title 39 applies to any release of any part of the proposal.
