D. § 260.2, titled "Availability of information; confidentiality of information" is amended by the following:

1. § 260.2(a). Any information provided to [the DEQ] under [R18-8-260 through R18-8-266 and R18-8-268 shall] be made available to the public to the extent and in the manner authorized by the [Hazardous Waste Management Act (HWMA), A. R. S. § 49-921 et seq.; the Open Meeting Law, A. R. S. § 38-435 et seq.; the Public Records Statute, A. R. S. § 39-121 et seq.; the Administrative Procedure Act, A. R. S. § 41-1001 et seq.; and rules promulgated pursuant to the above-referenced statutes], as applicable.

2. § 260.2(b) is replaced with the following:

a. The DEQ shall make a record or other information, such as a document, a writing, a photograph, a drawing, sound or a magnetic recording, furnished to or obtained by the DEQ pursuant to the HWMA and regulations promulgated thereunder, available to the public to the extent authorized by the Public Records Statute, A. R. S. §§ 39-121 et seq.; the Administrative Procedure Act, A. R. S. §§ 41-1001 et seq.; and the HWMA, A. R. S. §§ 49-921 et seq. Specifically, the DEQ shall disclose the records or other information to the public unless:

i. A statutory exemption authorizes the withholding of the information; or

ii. The record or other information contains a trade secret concerning processes, operations, style of work, or apparatus of a person, or other information that the Director determines is likely to cause substantial harm to the person's competitive position.

b. Notwithstanding subsection (a):

i. The DEQ shall make records and other information available to the EPA upon request without restriction;

ii. As required by the HWMA and regulations promulgated thereunder the DEQ shall disclose the name and address of a person who applies for, or receives, a HWM facility permit;

iii. The DEQ and any other appropriate governmental agency may publish quantitative and qualitative statistics pertaining to the generation, transportation, treatment, storage, or disposal of hazardous waste; and

iv. An owner or operator may expressly agree to the publication or to the public availability of records or other information.

c. A person submitting records or other information to the DEQ may claim that the information contains a confidential trade secret or other information likely to cause substantial harm to the person's competitive position. In the absence of such claim, the DEQ shall make the information available to the public on request without further notice. No claim of confidentiality may be asserted by any person with respect to information entered on a Hazardous Waste Manifest (EPA Form 8700- 22), a Hazardous Waste Manifest Continuation Sheet (EPA Form 8700-22A), or an electronic manifest format that may be prepared and used in accordance with 40 CFR 262.20(a)(3). EPA will make any electronic manifest that is prepared and used in accordance with § 262.20(a)(3), or any paper manifest that is submitted to the system under §§ 264.71(a)(6) or 265.71(a)(6) available to the public under this section when the electronic or paper manifest is a complete and final document. Electronic manifests and paper manifests submitted to the system are considered by EPA to be complete and final documents and publicly available information after 90 days have passed since the delivery to the designated facility of the hazardous waste shipment identified in the manifest. A person making a claim of confidentiality shall assert the claim:

i. At the time the information is submitted to, or otherwise obtained by, the DEQ;

ii. By either stamping or clearly marking the words "confidential trade secret" or "confidential information" on each page of the material containing the information. The person may assert the claim only for those portions or pages that actually contain a confidential trade secret or confidential information; and

iii. During the course of a DEQ inspection, or other observation, pursuant to the administration of the HWMA Program, by clearly indicating to the inspector which specific processes, operations, styles of work, or apparatus constitute a trade secret. The inspector shall record the claim on the inspection report and the claimant shall sign the report.

d. The Director shall provide the claimant with an opportunity to submit written comments to demonstrate that the information constitutes a legitimate confidential trade secret or confidential information. The comments shall be limited to confidential use by the DEQ pursuant to A. R. S. § 49-928. Pertinent factors to be considered by the Director for making a determination of confidentiality, and that the claimant may address in the claimant's written comments, include the following:

i. Whether the information is proprietary;

ii. Whether the information has been disclosed to persons other than the employees, agents, or other representatives of the owner; and

iii. Whether public disclosure would harm the competitive position of the claimant.

e. The Director shall make a determination of each confidentiality claim using the following procedures:

i. When a claim of confidentiality is asserted for information submitted as part of a HWM facility permit application:

(1) The claimant shall submit written comments demonstrating the legitimacy of the claim of confidentiality; and

(2) The Director shall evaluate the confidentiality claim and notify the claimant of the result of that determination as part of the completeness review pursuant to R18-8-271(C).

ii. When a claim of confidentiality is asserted for information submitted or obtained during an inspection, or for any other information submitted to or obtained by the DEQ pursuant to this Article, but not as part of a HWM facility permit application:

(1) The claimant may submit written comments demonstrating the legitimacy of the claim of a confidential trade secret or other confidential information within 10 working days of asserting the confidentiality claim; and

(2) If a request for disclosure is made, the Director shall evaluate the confidentiality claim and notify the claimant of the result of that determination. In all other instances, the Director may, on the Director's own initiative, evaluate the confidentiality claim and notify the claimant of the result of that determination within 20 working days after the time for submission of comments.

iii. When any person, hereinafter referred to as the "requestor," submits a request to the DEQ for public disclosure of records or information, the DEQ shall disclose the records or information to the requestor unless the information has been determined to be confidential by the Director, or is subject to a claim of confidentiality that is being considered for determination by the Director.

(1) If a confidentiality claim is under consideration by the Director, the requestor shall be notified that the information requested is under a confidentiality claim consideration and therefore is unavailable for public disclosure pending the Director's determination pursuant to subsection (D)(2)(e)(ii)(2).

(2) When a request for disclosure is made, the claimant shall be notified, within seven working days by certified mail with return receipt requested, that the information under a claim of confidentiality has been requested and is subject to the Director's determination pursuant to subsection (D)(2)(e)(ii)(2).

(3) If the Director disagrees with the confidentiality claim, the claimant shall have 20 working days to submit written comments either agreeing or disagreeing with the Director's evaluation.

(4) If a confidentiality claim is denied by the Director, the Director may request the attorney general to seek a court order authorizing disclosure pursuant to A. R. S. § 49-928.

f. Records or information determined by the Director to be legitimate confidential trade secrets or other confidential information shall not be disclosed by the DEQ at administrative proceedings pursuant to A. R. S. § 49-923(A) unless the following procedure is observed:

i. The DEQ shall notify both the claimant and the hearing officer of its intention to disclose the information at least 30 days prior to the hearing date. The DEQ shall send with the notice a copy of the confidential information that the DEQ intends to disclose;

ii. The claimant and the DEQ shall be allowed 10 days to present to the hearing officer comments concerning the disclosure of such information;

iii. The hearing officer shall determine whether the confidential information is relevant to the subject of the administrative proceeding and shall allow disclosure upon finding that the information is relevant to the subject of the administrative proceeding;

iv. The hearing officer may set conditions for disclosure of confidential and relevant information or the making of protective arrangements and commitments as warranted; and

v. The hearing officer shall give the claimant at least five days' notice before allowing disclosure of the information in the course of the administrative proceeding.
