2. (2) Definitions.

   1. (A) Confidential business information—Secret processes, secret methods of manufacture or production, trade secrets, and other information possessed by a business that, under existing legal concepts, the business has a right to preserve as confidential, and to limit its use by not disclosing it to others in order that the business may obtain or retain business advantages it derives from its rights in the information.

1. 2. The name, address (or description of the location),

and the nature of the emissions unit necessary to identify the emission units including a description of the device, equipment, or operation constituting the emissions unit; and

1. (C) Definitions of certain terms specified in this rule, other than those defined in this rule section, may be found in 10 CSR 10-6.020.

1. (3) General Provisions. Any information or records submitted or obtained pursuant to Chapter 643, RSMo, is subject to public disclosure unless a request for confidentiality is made by the person submitting the information or records and the request has been approved pursuant to the following procedures:

   1. (A) Procedures.

      1. 1. An owner or operator who wishes to claim confidentiality

for any information submitted pursuant to this rule or other rules of the commission should submit a claim of confidentiality when the information is initially submitted. Failure to submit a claim of confidentiality when the information is initially submitted may result in public disclosure.

1. 2. The claim of confidentiality shall be accompanied by

a justification that the information is entitled to confidential treatment.

1. 3. When information claimed to be confidential is being

submitted with a permit application, emissions report, or any other documentation containing information subject to public disclosure, a separate version that may be viewed by the public shall be provided by the owner or operator.

1. 4. Upon receipt of a claim of confidentiality, the director

shall evaluate the claim and inform the owner or operator that the claim has been approved, or that a preliminary decision has been made to deny the claim in whole or in part. Until that time in which the claim is reviewed it shall be held in confidence.

1. 5. If a claim of confidentiality is denied in the preliminary

review, the owner or operator will have fifteen (15) days from the date of the denial letter to submit further justification or comments to the director for consideration in the final decision on confidentiality. The director shall inform the owner or operator of his/her final decision on whether the claim will be denied in whole or in part within ten (10) working days of receiving the owner or operator’s further justification or comments.

1. 6. The owner or operator may appeal the director’s final

decision to deny a claim of confidentiality, in whole or part, to the administrative hearing commission pursuant to section 621.250, RSMo, and 10 CSR 10-1.030. Upon the timely filing of a notice of appeal, the confidentiality of the information shall be preserved until the entry of a final order by the commission.

1. 7. If the commission’s final decision is to deny the claim of

confidentiality, in whole or in part, the director shall treat the information as subject to public disclosure unless the owner or operator files a timely action for judicial review pursuant to section 536.110, RSMo. If a timely action for judicial review is filed, the confidentiality of the information shall be preserved until adjudication of the matter upon judicial review.

1. 8. A claim of confidentiality under this rule shall be

approved if—

1. A. The owner or operator has asserted a business

confidentiality claim that has not expired by its terms or been withdrawn;

1. B. The owner or operator has satisfactorily shown that

it has taken reasonable measures to protect the confidentiality of the information and that it intends to continue to take those measures;

1. C. The information is not, and has not been, reasonably

obtained without the owner’s or operator’s consent by other persons (other than governmental bodies) by use of legitimate means (other than discovery based on a showing of special needs in a judicial or quasi-judicial proceeding);

1. D. No statute specifically requires public disclosure of

the information;

1. E. The information is not emission data; and

2. F. The owner or operator has satisfactorily shown that—

   1. (I) Public disclosure of the information is likely to

cause substantial harm to the business’ competitive position; or

1. (II) The information was voluntarily submitted and

if disclosed, the submitter would be reluctant to provide additional information to the director in the future. Information is voluntarily submitted if the facility has no statutory, regulatory, or contractual obligation to provide the information; or the director has no statutory, regulatory, or contractual authority to obtain the information under federal or state law; and

1. (B) Conditions for Any Disclosure.

   1. 1. Public request. Upon receipt of a request from a member

of the public for release of any information submitted under a claim of confidentiality, and for which the claim has not been finally denied, the director shall inform both the person making the request and the owner or operator that the request for the information is denied or that a tentative decision has been made to release the information. A preliminary decision to release the information shall be treated in the same manner as a preliminary decision to deny a claim of confidentiality under paragraphs (3)(A)4.–8. of this rule.

1. 2. Confidential and public information. If information

entitled to confidentiality cannot reasonably be separated from information not entitled to confidentiality, all the information must be treated as subject to public disclosure.

1. 3. Public release. The director and his/her designees

shall not release to the public, or place in the public file, any information for which a claim of confidentiality has been made until the procedures under paragraphs (3)(A)4.–8. and (3) (B)1. of this rule have been observed.

1. 4. Disclosure to local agencies. Information submitted

under a claim of confidentiality, where the claim has not been finally denied, may be disclosed to local air pollution control agencies if—

1. A. The owner or operator is given prior notice fifteen

1. (15) working days in which to obtain an order from a court of competent jurisdiction restraining or enjoining the disclosure to the local agency, and if no such order is obtained, or obtained and later dissolved; or

   1. B. The local agency has ordinances or regulations

respecting the treatment of confidential business information that is equivalent to this rule, the director provides notice to the owner or operator that the information is being disclosed to the local agency, and the director informs the local agency that the information is subject to a claim of confidentiality.

1. 5. Disclosure to administrator. Information submitted

under a claim of confidentiality, where the claim has not been finally denied, may be disclosed to the administrator provided the administrator agrees, pursuant to 40 CFR 2.215, that the information will be kept confidential.

1. 6. Subpoenas for confidential information. The director

shall respond to subpoenas and discovery requests for information submitted under a claim of confidentiality, if the claim has not been finally denied, in a manner that is designed to preserve the claim of confidentiality until a confidentiality determination is made by a court or other tribunal of competent jurisdiction.
