Midland, Michigan 48640 

Dear Ms. Arnold: 

Thank you for the equipment component screening and bagging data you 

provided to the U. S. Environmental Protection Agency (EPA) for your company's 

butadiene production facility in Freeport, Texas, in response to our 

October 21, 1988, letter. The screening and bagging data will enable us to 

calculate equipment component leak frequencies and thereby determine 

relatively high- and low-leak facilities. Additional information is being 

requested to enable us to identify and validate any work practices or 

equipment design specifications that effectively reduce equipment component 

leaks of volatile organic compounds (VOC) and volatile hazardous air 

pollutants (VHAP). For this purpose, EPA requests that you supply the 

information contained in Enclosure 1 for your butadiene production facility in 

Freeport, Texas. We are sensitive to the amount of labor required to respond 

to this request and have tried to minimize demands on your time by limiting 

the questionnaire to features important to regulatory development. 

The authority for the EPA's information gathering is included in 

Section 114 of the Clean Air Act (42 U.S.C. 7414). Enclosure 2 contains a 

summary of this authority. If you believe that disclosure of specific pieces 

of information you submit would reveal a trade secret, you should clearly 

identify such information as discussed in the enclosure. Any information 

subsequently determined to constitute a trade secret will be protected under 

18 U.S.C. 1905. If no claim of confidentiality is made concerning the 

information obtained by EPA, it may be made available to the public by EPA 

without further notice (40 CFR Part 2.203, September 1, 1976). Enclosure 3 

summarizes Agency and Emission Standards Division policies and procedures for 

handling privileged information and describes the EPA contractor commitments 

and procedures for use of confidential materials. It is the EPA's policy that 

compliance by an authorized representative with the requirements detailed in 

Enclosure 3 provides sufficient protection for the rights of submitters of 

privileged information. 
P.3 

The EPA has contracted with Radian Corporation (Contract No. 68-02-4378) 

to obtain information pertinent to this investigation. Thus, as noted in 

Enclosure 4, Radian has been designated by EPA as an authorized representative 

of the Agency. Therefore, Radian has the rights discussed above and in 

Enclosure 2. As a designated representative of the Agency, Radian is subject 

to the provisions of 42 U.S.C. 7414(c) respecting confidentiality of methods 

and processes entitled to protection as trade secrets. 

If you have any questions regarding this request or need additional 

explanation about our confidentiality procedures, please call 

Mr. David Markwordt of EPA at (919) 541-0837 or Mr. Ed Moretti of Radian at 

(919) 541-9100. If you are unable to provide the information we have 

requested by January 27, 1989, please contact Mr. Markwordt. Thank you for 

your help with this project. 

Sincerely, 

Susan R. Wyatt, Chief

EPA's Information Gathering Authority 

Under Section 114 of the Clean Air Act 

Under Section 114 ofthe Act (42 U.S.C. 7414), Congress has given the 

U. S. Environmental Protection Agency broad authority to secure information 

needed "(a) for the purpose (i) of developing or assisting in the development 

of any implementation plan under Section 110 or 111(d), any standard of 

performance under Section 111, or any emission standard under Section 112 (ii) 

of determining whether any person is in violation of any such standard or any 

requirement of such a plan, or (iii) carrying out any provision of this Act." 

Among other things, Section 114 authorizes EPA to make inspections, conduct 

tests, examine records, and require owners or operators of emission sources to 

submit information reasonably required for the purpose of developing such 

standards. In addition, the EPA Office of General Counsel has interpreted 

Section 114 to include authority to photograph or require submission of 

photographs of pertinent equipment, emissions, or both. 

Under Section 114, EPA is empowered to obtain information described by 

that section even if you consider it to be confidential. You may, however, 

request that EPA treat such information as confidential. Information obtained 

under Section 114 and covered by such a request will ordinarily be released to 

the public only if EPA determines that the information is not entitled to 

confidential treatment.* Procedures to be used for making confidentiality 

determinations, substantiative criteria to be used in such determinations, and 

special rules governing information obtained under Section 114 are set forth 

in 40 CFR Part 2 published in the Federal Register on September 1, 1976 (40 FR 

36902). 

'Section 114 requires public availability of all emission data and 

authorizes disclosure of confidential information in certain circumstances, 

See 40 FR 36902 - 36912 (September 1, 1976). 
P.19 

Enclosure 2 (continued) 

Pursuant to 2.204(a) of EPA's Freedom of Information Act (FOIA) 

regulation, in the event a request is received, or it is determined that a 

request is likely to be received, or EPA desires to determine whether business 

information in its possession is entitled to confidential treatment even 

though no request for release of the information has been received, please be 

advised that EPA will seek, at that time, the following information to support 

your claim as required by 2.204 (e)(4) of EPA's FOIA regulations: 

' 1. Measures taken by your company to guard against undesired disclosure 

of the information to others; 

2. The extent to which the information has been disclosed to others, 

and the precautions taken in connection therewith; 

3. Pertinent confidentiality determinations, if any, by EPA or other 

Federal agencies, and a copy of any such determinations, or reference to it, 

if available; and 

4. Whether your company assserts that disclosure of the information 

would be likely to result in substantial harmful effects on the business' 

competitive position, and if so, what those harmful effects would be, why they 

should be viewed as substantial, and an explanation of the causal relationship 

between disclosure and such harmful effects.

EPA's Information Gathering Authority Under 

Section 3007 of the Resource Conservation 

and Recovery Act 

The authority to obtain samples and information is provided by Section 

3007 of the Resource Conservation and Recovery Act of 1976, as amended, 42 

U.S.C. 6927 (RCRA). "For the purpose of developing or assisting in the 

development of any regulation," ...and upon request by a duly designated EPA 

officer, Section 3007 authorizes an EPA employee (1) to enter any 

establishment where hazardous wastes are generated, stored, treated, 

transported, disposed of, or handled; (2) to inspect and obtain samples of 

such wastes; (3) to inspect or copy records relating to such waste. If 

requested prior to leaving the premises with the samples, the EPA employee 

shall give a descriptive receipt and a portion of the samples to the 

establishment's agent. A copy of the results of all analyses subsequently 

performed on the samples shall also be furnished to the establishment's agent. 

Information may not be withheld from the Administrator or his authorized 

representative because it is confidential. However, when requested to do.so, 

the Administrator is required to consider information to be confidential and 

to treat it accordingly, if disclosure would divulge methods or processes 

entitled to protection as trade secrets. EPA regulations concerning 

confidentiality of business information are contained in 40 CFR Part 2, 

Subpart B (42 Federal Register 36902-36924 (September 1, 1976), as amended by 

43 FR 39997 (September 8, 1978), and 44 FR 17673 (March 23, 1979). These 

regulations provide that a business may, if it desires, assert a business 

confidentiality claim covering part or all of the information furnished to 

EPA. The manner of asserting such claims is specified in 40 CFR 2.203(b). 

Information covered by such a claim will be treated by the Agency in 

accordance with the procedures set forth in the Subpart B regulations. In the 

event that a request is made for release of information covered by a claim of 

confidentiality, or the Agency otherwise decides to make a determination 

whether or not such information is entitled to confidential treatment, notice 

will be provided to the business which furnished the information. No 

information will be disclosed by EPA as to when a claim of confidentiality has 

been made except to the intent and in accordance with 40 CFR Part 2, Subpart 

B. However, if no claim of confidentiality is made when information is 

furnished to EPA, the information may be made available to the public without 

notice to the business. 

Businesses should transmit RCRA Confidential Business Information to EPA 

by registered mail, return receipt requested, in a double envelope. The inner 

envelope should be addressed specifically to the appropriate contact person 

with the following additional wording on the front: "RCRA Confidential 

Business Information To Be Opened by Addressee Only." The outer envelope 

should be addressed to the appropriate contact person without the additional 

wording.

authorized representatives; (3) contain provisions for the release of 

information to the Congress, Comptroller General, other Federal agencies, 

State and local governments, and Courts; (4) permit the disclosure of 

information; and (5) prohibit wrongful use of such Information and cite 

penalties for wrongful disclosure. Further, the regulations contain the 

Agency's basic rule concerning the treatment of requests for information under 

the Freedom of Information Act (5 U. S. C. 552). 
P.25 

6. Procedures: 

a. Requests for Information 

Each request originating in the ESD for information made under the 

provisions of Section 114(a) is signed by the Division Director. The request 

includes ESD's standard enclosure "EPA's Information Gathering Authority Under 

Section 114 of the Clean Air Act," which was designed to meet the requirement 

of 40 CFR Part 2 discussed above. 

b. Receipt of Confidential Business Information 

Upon receipt of information for which confidential treatment has been 

requested, the Office of the Director (OD) directs the logging of the material 

and the establishment of a permanent file. If confidential treatment is 

requested, but is not specifically marked, the material will be stamped 

"Subject to Confidentiality Claim." If part of the material is claimed to be 

confidential, that portion Is marked "Subject to Confidentiality Claim." In 

compliance with Section 2.204 and 2.208 of 40 CFR Part 2, the Branch Chief 

responsible for the requested information reviews the information to determine 

whether it is likely to be confidential in contrast to being available in the 

open literature, whether it is emission data, and whether it likely provides 

its holder with a competitive advantage. If the information is clearly not 

confidential, the Branch Chief prepares a letter for signature of the Division 

Director, ESD, to notify the business of this finding. If the information is 

possibly confidential, the Branch Chief sends a memorandum to inform the OD, 

ESD, of this finding, gives a brief description of the material (what it is, 

how many pages, etc.), identifies it with the correct ESD project number, and 

lists those persons who are authorized to have access to the information. The 

information and memorandum are hand carried to the OD and placed in the CBI 

files with the material. A record of who will see the information (Attachment 

A) is also filed with the folder containing the information. If CBI is 

received from the owner via an authorized representative or a third party, the 

same procedure is followed, with the addition of clearly identifying the 

information and its source. By regulation, information for which confidential 

treatment is requested must be so marked or designated by the submitter. The 

EPA takes additional measures to ensure that the proprietary designation is 

uniformly indicated and immediately observable. All unmarked or undesignated 

information (except as noted below) is freely releasable. 
P.26 

c. Storage of Confidential Business Information 

Folders, documents, or material containing CBI (as defined) shall be 

secured, at a minimum, in a combination-locked cabinet. Normal ESD procedure 

is to secure this information in a cabinet equipped with a security bar and 

locked using a four-way, changeable combination padlock. In addition, the 

entrance door to the CBI storage room is equipped with a changeable 

combination simplex lock. The locked files are under the control of the OD. 

Knowledge of the combinations of the locking devices is limited to the 

Document Control Officer (DCO) and the minimum number of persons required to 

effectively maintain normal business operations. Records of the locking 

device combination are stored elsewhere in conformance with the requirements 

of the EPA Security Manual. 

Combinations of the locks are normally changed whenever a person with 

knowledge of the combinations is transferred, terminates employment, no longer 

authorized access, or whenever the possibility exists that the combinations 

may have been subject to compromise. 

Files may be checked out upon confirmation that the requesting person is 

authorized to receive the information. All confidential files must be 

returned no later than 4:00 p.m. on the same day they are removed. The 

intended user must sign the CBI Control Records when the file is checked out. 

The individual who signs out a confidential file is responsible for its 

safekeeping. The file must not be left unattended. The information must not 

be disclosed to any non-authorized personnel. 

Storage procedures for CBI by an authorized representative of EPA (see 

Section d. below) must be, at a minimum, as secure as those established for 

EPA offices within OAQPS. Whenever CBI is removed from the EPA files to be 

transmitted to an authorized representative, a memorandum is placed in the 

file indicating what information was transmitted, the date, and the recipient. 

The authorized representative returns a signed receipt to the DCO. 

d. Access to Confidential Business Information 

Only authorized EPA employees may open and distribute CBI. 

Only employees who require and are authorized access to CBI in the 

performance of their official duties are permitted to review documents and, 

upon receiving a confidential document, must sign and date the form shown in 

Attachment A to certify their access to the document. 
The CBI files are controlled by the OD, ESD, and maintained by a 

contractor cleared for access as an authorized representative. Access to the 

information is limited to those persons having a need to know in performing 

their official duties. 

The ESD Branch having primary interest in thg CBI provides a memorandum 

for the record designating those personnel who are authorized to use CBI in a 

program under which CBI can be requested. No person is automatically entitled 

to access based solely on grade, position, or security clearance. The names 

of persons granted access to CBI are placed on the Clean Air Act CBI access 

list, which indicates the specific CBI each person is permitted to see. The 

access "Hst is reviewed and updated periodically. 

Companies under contract to perform work for EPA may be designated 

authorized representatives of EPA if such designation is necessary in order 

for the contractor to carry out the work required by the contract. As 

authorized representatives, contractors may be granted access to CBI by the 

Director, ESD. The following conditions apply when it has been determined 

that disclosure is necessary: 

(1) The contractor designated as a representative and its employees (a) 

may use such confidential information only for the purpose of carrying out the 

work required, (b) must refrain from disclosing the information to anyone 

other than EPA without having received from EPA prior written approval of each 

affected business or of an EPA legal office, and (c) must return to EPA all 

copies of the information (and any abstracts or excerpts therefrom) upon 

request or whenever th© information is no longer required for the performance 

of the work. 

(2) The authorized contractor designated as a representative must 

obtain a written agreement from each of its employees who will have access to 

the information. A copy of each employee agreement (Attachment B) must be 

furnished to EPA before access is permitted. 

(3) The contractor designated as an authorized representative must 

agree that the conditions in the contract concerning the use and disclosure of 

CBI are included for the benefit of, and shall be enforceable by, both EPA and 

any affected business having a proprietary interest in the information. 

Information may be released to or accessed by EPA employees other than 

OAQPS employees only upon approval of the Director, ESD. 
Requests for CBI from other Federal agencies, Congress, the Comptroller 

General, Courts, etc., are processed by the OD, ESD, in accordance with 40 CFR 

2, Subpart B. 

Requests under the Freedom of Information Act are handled in accordance 

with 40 CFR 2, Subpart A. The ESD Freedom of Information Coordinator must be 

consulted prior to responding to any request for information if a claim of 

confidentiality has been asserted or if there is reason to believe that a 

claim might be made if the business knew release was intended. 

e. Use and Disclosure of Confidential Business Information 

The CBI as defined may not be used in publications, supporting 

documents, memoranda, etc., that become a part of the public domain, except as 

provided for in 40 CFR 2 Subpart B. 

The CBI may not be summarized without the approval of the Project 

Manager responsible for the CBI. Any authorized reproduction shall be 

provided by the CBI office staff. Further, all authorized reproductions must 

be introduced into the CBI control system and treated according to the same 

procedures applicable to the original confidential material. 

The EPA generated documents or material, or extracts of information 

containing CBI, must be stamped "Subject to Confidentiality Claim" and a cover 

sheet must be attached to Identify the material as CBI. 

f. Handling of Other Information 

Reports, memoranda, documents, etc., prepared by EPA or its authorized 

representatives are not normally circulated outside EPA for comments or review 

prior to publication except in such cases as described above (6.d.3) wherein 

CBI is expressly included. However, because industrial-data-gathering visits, 

plant inspections, and source testing can involve inadvertent receipt of CBI, 

it is the policy of ESD to protect all parties involved in the following 

manner. 

Prior to or at the inception of a plant inspection, data-gathering 

visit, or source test, EPA or its authorized representative discusses with a 

responsible industry official the information sought, how it is to be used, 

and how it is to be protected. A copy of this summary is usually provided to 

the industry official being consulted. 

Following an inspection, visit, or test, a trip report is prepared to 

include, as practicable, all information received by EPA or its authorized 

representative during the visit or test. The report may be prepared by either 

_| !_»•« i___^i_ tBM 
P.29 

EPA or Its authorized representative. The draft of that report 1s clearly 

identified, on an attached, colored cover sheet as "Confidential Pending 

Determination." A second copy of the draft trip report 1s forwarded by EPA to 

the responsible industry official for review. The responsible industry 

official is requested by cover letter to review the report, clearly mark any 

information considered to be confidential, and return the marked up-report to 

the responsible EPA employee within 2 weeks of receipt. The original draft is 

kept in the CBI "pending" file until the marked-up copy is returned by the 

business firm. 

When the reviewed copy of the report, as marked by the responsible plant 

official, 1s received by EPA, Information designated confidential 1s placed in 

the CBI files as described above. The original draft of the trip report is 

edited to delete the confidential information and to accommodate technical 

changes, and the trip report is issued.
