(e) Substantive criteria for use in confidentiality determinations. Section 2.208 applies to information to which this section applies, except that information which is emission data, a standard or limitation, or is collected pursuant to section 211(b)(2)(A) of the Act is not eligible for confidential treatment. No information to which this section applies is voluntarily submitted information.

(f) Availability of information not entitled to confidential treatment. Section 2.210 does not apply to information to which this section applies. Emission data, standards or limitations, and any other information provided under section 114 or 208 of the Act which is determined under this subpart not to be entitled to confidential treatment, shall be available to the public notwithstanding any other provision of this part. Emission data and standards or limitations provided in response to a subpoena issued under section 307(a) of the Act shall be available to the public notwithstanding any other provision of this part. Information (other than

emission data and standards or limitations) provided in response to a subpoena issued under section 307(a) of the Act, which is determined under this subpart not to be entitled to confidential treatment, shall be available to the public, unless EPA determines that the information is exempt from mandatory disclosure under 5 U.S.C. 552(b) for reasons other than reasons of business confidentiality and cannot or should not be made available to the public.

(g) Disclosure of information relevant to a proceeding. (1) Under sections 114, 208 and 307 of the Act, any information to which this section applies may be released by EPA because of the relevance of the information to a proceeding, notwithstanding the fact that the information otherwise might be entitled to confidential treatment under this subpart. Release of information because of its relevance to a proceeding shall be made only in accordance with this paragraph (g).

(2) In connection with any proceeding other than a proceeding involving a decision by a presiding officer after an evidentiary or adjudicatory hearing, information to which this section applies which may be entitled to confidential treatment may be made available to the public under this paragraph (g)(2). No information shall be made available to the public under this paragraph (g)(2) until any affected business has been informed that EPA is considering making the information available to the public under this paragraph (g)(2) in connection with an identified proceeding, and has afforded the business a reasonable period for comment (such notice and opportunity to comment may be afforded in connection with the notice prescribed by §2.204(d)(1) and §2.204(e)). Information may be made available to the public under this paragraph (g)(2) only if, after consideration of any timely comments submitted by the business, the General Counsel determines that the information is relevant to the subject of the proceeding and the EPA office conducting the proceeding determines that the public interest would be served by making the information available to the public. Any affected business shall be given at least 5 days' notice by the General Counsel prior to

making the information available to the public.

(3) In connection with any proceeding involving a decision by a presiding officer after an evidentiary or adjudicatory hearing, information to which this section applies which may be entitled to confidential treatment may be made available to the public, or to one or more parties of record to the proceeding, upon EPA's initiative, under this paragraph (g)(3). An EPA office proposing disclosure of information under this paragraph (g)(3), shall so notify the presiding officer in writing. Upon receipt of such a notification, the presiding officer shall notify each affected business that disclosure under this paragraph (g)(3) has been proposed, and shall afford each such business a period for comment found by the presiding officer to be reasonable under the circumstances. Information may be disclosed under this paragraph (g)(3) only if, after consideration of any timely comments submitted by the business, the EPA office determines in writing that, for reasons directly associated with the conduct of the proceeding, the contemplated disclosure would serve the public interest, and the presiding officer determines in writing that the information is relevant to a matter in controversy in the proceeding. The presiding officer may condition disclosure of the information to a party of record on the making of such protective arrangements and commitments as he finds to be warranted. Disclosure to one or more parties of record, under protective arrangements or commitments, shall not, of itself, affect the eligibility of information for confidential treatment under the other provisions of this subpart. Any affected business shall be given at least 5 days notice by the presiding officer prior to making the information available to the public or to one or more of the parties of record to the proceeding.

(4) In connection with any proceeding involving a decision by a presiding officer after an evidentiary or adjudicatory hearing, information to which this section applies may be made available to one or more parties of record to the proceeding, upon request of a party, under this paragraph (g)(4). A party of record seeking disclosure of informa

tion shall direct his request to the presiding officer. Upon receipt of such a request, the presiding officer shall notify each affected business that disclosure under this paragraph (g)(4) has been requested, and shall afford each such business a period for comment found by the presiding officer to be reasonable under the circumstances. Information may be disclosed to a party of record under this paragraph (g)(4) only if, after consideration of any timely comments submitted by the business, the presiding officer determines in writing that (i) the party of record has satisfactorily shown that with respect to a significant matter which is in controversy in the proceeding, the party's ability to participate effectively in the proceeding will be significantly impaired unless the information is disclosed to him, and (ii) any harm to an affected business that would result from the disclosure is likely to be outweighed by the benefit to the proceeding and to the public interest that would result from the disclosure. The presiding officer may condition disclosure of the information to a party of record on the making of such protective arrangements and commitments as he finds to be warranted. Disclosure to one or more parties of record, under protective arrangements or commitments, shall not, of itself, affect the eligibility of information to confidential treatment under the other provisions of this subpart. Any affected business shall be given at least 5 days notice by the presiding officer prior to making the information available to one or more of the parties of record to the proceeding.

(ii) No information shall be disclosed under this paragraph (h)(2), unless this contract or subcontract in question provides:

(A) That the contractor or subcontractor and the contractor's or subcontractor's employees shall use the information only for the purpose of carrying out the work required by the contract or subcontract, shall refrain from disclosing the information to anyone other than EPA without the prior written approval of each affected business or of an EPA legal office and shall return to EPA all copies of the information (and any abstracts or extracts therefrom) upon request by the EPA program office, whenever the information is no longer required by the contractor or subcontractor for the performance of the work required under the contract or subcontract, or upon completion of the contract or subcontract (where the information was provided to the contractor or sub

contractor by an agency other than EPA, the contractor may disclose or return the information to that agency);

(B) That the contractor or subcontractor shall obtain a written agreement to honor such terms of the contract or subcontract from each of the contractor's or subcontractor's employees who will have access to the information, before such employee is allowed such access; and

(iv) The EPA program office shall prepare a record of each disclosure under this paragraph (h)(2), showing the contractor or subcontractor, the contract or subcontract number, the information disclosed, the date(s) of disclosure, and each affected business. The EPA program office shall maintain the record of disclosure and the determination of necessity prepared under paragraph (h)(2)(i) of this section for a period of not less than 36 months after the date of the disclosure.

(3) A state or local governmental agency which has duties or responsibilities under the Act, or under regulations which implement the Act, may be considered an authorized representative of the United States for purposes of this paragraph (h). Information to which this section applies may be fur

The presiding officer may condition disclosure of the information to a party of record on the making of such protective arrangements and commitments as he finds to be warranted.
