Mr. Daria Partovi 

Enduro Composite Systems 

7100 Old Katy Road JUN 24 1996 

Houston, Texas 77024-2112 

Dear Mr. Partovi: 

This letter is to confirm a visit to the Enduro Composite 

Systems facility located in Fort Worth, Texas, by representatives 

of the U.S. Environmental Protection Agency (EPA) on Tuesday, 

July 9, 1996. Visitors will include Dr. Madeleine Strum of the 

EPA, and Dr. Kenneth Meardon and Ms. Melanie Proctor of Pacific 

Environmental Services, Inc. (PES). The visit was discussed 

during a telephone conversation between you and Dr. Meardon on 

June 18, 1996. 

As you know, the EPA has undertaken a program to develop 

national emission standards for hazardous air pollutants for 

reinforced plastic composites production under section 112 of the 

Clean Air Act (Act), as amended November 1990. As part of this 

activity, we have been gathering information on composites 

processes and associated air pollution control measures for some 

time. Due to the add-on control equipment present at Enduro, 

your facility is of great importance for determining maximum 

achievable control technology for continuous lamination 

processes, particularly with regard to new sources. A visit to 

your facility would assist us in assessing feasible emission 

reduction measures and the variability in continuous lamination 

processes. We understand that the add-on control device was 

originally used to control both continuous lamination and 

pultrusion emissions, but that Enduro has discontinued its 

pultrusion operation. This visit would also provide the 

opportunity to discuss your experiences with controlling 

pultrusion emissions. 

The types of information we would like to discuss with you 

during the site visit are detailed in Enclosure 1, and include 

the following: 
P.3 

1. Description of the plant itself - size, hours of 

operation, layout of production processes, types and market 

position of products manufactured, and production rate; 

2. Detailed description of the continuous lamination 

process, including the application equipment used, types of 

resins, and continuous lamination machine parameters; 

3. Descriptions of the emissions capture and control 

system(s) and other measures used to limit emissions from 

the continuous lamination process including estimate of 

effectiveness (capture plus destruction); 

4. Reason(s) for discontinuing the pultrusion operation 

and experiences with controlling pultrusion emissions; and 

5. Available cost information concerning the control 

measures discussed under item 3. 

Enclosure 1 is an outline of the site visit checklist that 

EPA and PES will use during the site visit. Please note that 

some questions may be modified as we learn more about your 

operations. 

Most of the information on the checklist will be obtained 

during the discussions at the facility. However, some of the 

information may have to be retrieved from your files in advance 

of the visit. We request that you read through the checklist and 

have the necessary information from your files available to the 

EPA representatives when they arrive at the plant. 

The authority for the EPA's information gathering is 

included in section 114 of the Act (42 U.S.C. 7414). Enclosure 2 

contains a summary of this authority. If you believe that 

disclosure of the information we request 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 accompanies the information when 

it is received by the EPA, it may be made available to the public 

by the EPA without further notice (40 CFR Part 2.203, 

September 1, 1976). Section 114 of the Act exempts emissions 
P.4 

data from claims of confidentiality and emissions data collected 

may be made available to the public. A clarification of what the 

EPA considers to be emissions data is contained in Enclosure 3. 

As noted in Enclosure 4, we have designated PES as an 

authorized representative of the EPA. Therefore, PES has the 

rights discussed above and in Enclosure 2. As an authorized 

representative of the EPA, PES is subject to the provisions of 42 

U.S.C. 7414 respecting confidentiality of methods or processes 

entitled to protection as trade secrets. The PES contract with 

the EPA is No. 68-D1-0116. 

Enclosure 5 summarizes the EPA's policies and procedures for 

handling privileged information and describes EPA contractor 

commitments and procedures for using confidential materials. It 

is the EPA's policy that compliance by an authorized 

representative with the requirements detailed in Enclosure 4 

provides sufficient protection for the rights of submitters of 

privileged information. 

The following policies concerning liability should also be 

of interest to you: 

1. If a Federal employee is. injured in the course of his 

or her employment, he or she has compensation coverage from the 

Government under the Federal Employees Compensation Act (5 U.S.C. 

8108 et seq.); and 

2. If, due to the employee's negligence, property damage 

or personal injury to third parties occurs, the Federal Tort 

Claim Act (28 U.S.C. 1346) provides a means of fixing any 

liability upon the Federal Government. 

The Office of General Counsel has informed the Agency that a 

firm may not condition the EPA's "right of entry" upon consent to 

a waiver of liability and has instructed employees not to sign 

such waivers. If you have any questions regarding this refusal, 

please contact Mr. Donnell L. Nantkes, Office of General Counsel, 

at (202) 260-4556. 
P.5 

If you have any questions regarding this request, please 

contact Dr. Madeleine Strum at (919) 541-2383.

SITE VISIT - ENDURO COMPOSITE SYSTEMS 

The EPA is attempting to determine the ways in which plastic 

composites manufacturing operations vary from one to another. 

We need to better understand the continous lamination process and 

the parameters (such as end-use properties, size, process 

combination, etc.) that could affect the technical feasibility of 

applying air emission controls. Further, we need to estimate the 

potential economic impact of air pollution controls on continuous 

lamination operations. To help ensure that we cover all areas 

that may affect the feasibility of applying air pollution 

controls at facilities with continuous lamination operations and 

their economic impacts, we have developed a detailed list of 

information that we would like to review with you during our 

visit. We have grouped this information into several major topic 

areas to help organize the material. Finally, we understand that 

your facility recently discontinued its pultrusion operations. 

We would like to discuss your experiences with controlling 

emissions from this process. 

To help prepare for the site visit, an * has been placed 

next to those items that we anticipate can be compiled by Enduro 

prior to the visit and provided to the EPA representatives with 

little, if any, discussion during the site visit. An ** has been 

placed next to those items that we anticipate will require 

compilation by Enduro prior to the visit. Finally, the items 

without any asterisks are those items for which we anticipate 

discussion only is required, with little, if any, compilation of 

materials by Enduro prior to the site visit.

Dear Ms. Dunston: 

This letter is response to your Octoter 17, 1995 fax requesting specific information on Enduro 

Composite Systems thermal oxidizer. The information provided below addresses the three 

questions asked in the fax: 

1. What is the volumetric flow rate into the control device? 

The flow into the thermal oxidizer is 15,000 SCFM. 

2. What is lhe inlet concentration of styrene (or other HAP) into the control device? 

Based on emission calculations using emission factors found in AP-42, Table 4.12-2 the inlet 

concentration of VOC is approximately 1000 ppm (178 ppm styrene, 12 ppm methyl ethyl 

ketone, 321 ppm toluene, and 489 ppm methyl methacrylate). 

Based on actual sampling done in July 1992 the inlet concentration was determined to be 

approximately 785 ppm using EPA Test Method 25A. 

3. Is the incinerator thermal or catalytic and who is the manufacturer? 

Enduro's "incinerator" is a thermal unit that operates at 1,400°F. The manufacturer ofthe unit 

is Smith Engineering of Ontario, CA. 

If you have any questions, please feel free to contact me at (817) 232-1127 - X657.

Enclosure oL 

EPA's Information Gathering Authority 

Under Section 114 of the Ctean 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 infonnation needed "for the purpose of (i) 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) determining whether any person is in violation of 

any such standard of 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 die 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, substantive criteria to be used in such determinations, and special rules 

governing infonnation obtained under Section 114 are set forth in 40 CFR Part 2 published in the Federal 

Register on September 1, 1976 (40 FR 36902). 

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 ofthe 

information has been received, please be advised diat 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 ofthe 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 asserts that disclosure of die 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 ofthe causal relationship between disclosure and 

such harmful effects. 

•"Section 114 requires public avaiability of all emission data and authorizes diclosure of confidential 

information in certain circumstances. See 40 FR 36902 - 36912 (September 1, 1976)

SUPPLEMENTARY INFORMATION: The EPA 

routinely uses the authority of sections 

110 and 114(a) of tha CAA to gather 

technical infonnation from industries 

involved in operations that lead to 

emission of pollutants to the ambient 

air. This information has been used, 

among other things, lo better 

characterize emitting facilities and to 

evaluate the need for and impacts of 

potential regulation. 

Information requests under sections 

110 and 114(a) of the CAA typically 

i.irluie questions on uncontrolW and 

controlled emission rates and emission 

parameters of the pollutant or group of 

pollutants of concern. The respondents 

sometimes claim that Its response 

constitutes trade secret information, and 

thus, should be treated as confidentiaL 

Claims of confidentiality may be made 

under section 114(c) of the CAA. which 

states: ***** upon a showing 

satisfactory to the Administrator by any 

person that records, reports, or 

Information, or a particular part thereof, 

(other than emission data) to which the 

Administrator has access under this 

section If made public, would divulge 

methods or processes entitled to 

protection as trade secrets of such 

person, the Administrator shall consider 

such* * * confidential In accordance 

with the purposes of section 1905 of title 

18 of the United Sutes Code* * Vl f 

the Administrator ao determines, the 

information is not disdosable to the 

public. 

However, section 114(c) of the CAA 

provides that infonnation claimed to be 

a trade secret but which constitutes 

emission data may not be withheld aa 

confidential. Although typically the EPA 

evaluates whether infonnation 

constitutes emission data on a case-bycase basts, it believes that some kinds of 

data will always constitute emission 

data within the meaning of section 

114(c). The purpose of this notice is to 

describe, without attempting to be 

comprehensive, that information which 

the ISPA generally considers to be 

emission data, and which cannot qualify 

as confidential under either section 

114(c) or section 110 (as set forth in 40 

CFR5L321.S1122sJid5U23)oftha 

CAA. The EPA is issuing this notice to 

clarify its policy and procedures, to 

facilitate the use of these data in 

automated data systems and computerbased simulation models, and to 

expedite processing ol claims for 

confidentiality or requests for 

disclosure. 

The EPA presently determines that 

data submitted to it aa emission data 

does not qualify as confidential If It 

meets the following definition under 40 

CFR2J01(a)(2)(t): 

a. Definitions. For the purpose of this 

section: (1) Act means the Clean Air 

Act as amended, 42 U.S.C 7401 et seq. 

(2)(i) Emission data means, with 

reference to any source of emission of 

any substance into the air— 

(A) Infonnation neassary to 

determine the identity, amount, 

frequency, concentration, or other 

characteristics (to the extent related to 

air quality) of any emission which has 

been emitted by the source (or of any 

pollutant resulting from any emission by 

the source), or any combination of the 

foregoing: 

(B) Infonnation necessary to 

determine the identity, amount, 

frequency, concentration, or other 

characteristics (to the extent related to 

air quality) of the emission which, under 

an applicable standard or limitation, the 

source was authorized to emit 

(including, to the extent necessary for 

such purposes. • description of the 

manner or rate of operation ot the 

source), or any combination of the 

foregoing: 

(C) A general description of the 

location and/or nature of the source to 

the extent necessary to Identify the 

source and to dUtinguish it from other 

sources (induding. to the extent 

necessary for such purposes, a 

description of the device. Installation, or 

operation constituting the source). 

The table below lists tha specific data 

fields which the EPA presently 

considers to constitute emission data 

and provides a brief description of what 

each data field describes. The 

descriptions are intended to provide 

general information. This list Is not 

exhaustive and. therefore, other data 

might be found, ln a proper case, to 

constitute emission data.

Summary of OAQPS 

Procedures for Safeguarding Clean Air Act (CAA) 

Confidential Business Information (CBI) 

1. Purpose 

This memorandum describes Agency policy and procedures pertaining to the handling Jind 

safeguarding of infomution that may be entitled to confidential treatment for reasons of business 

confidentiality by the OAQPS, Office of Air and Radiation, U.S. Environmental Protection 

Agency. 

2. Other Applicable Documents: < 

a. Clean Air Act as amended. 

b. 40 CFR, Chapter 1, Part 2, Subpart B - Confidentiality of Business Information. 

c. EPA Security Manual, Part II, Chapters 8 and 9. 

d. Clean Air Act Confidential Business Information Security Manual (June 1995 

edition). 

3. Exception: 

This document was prepared as a summary of data gathering and handling procedures 

used by the OAQPS, EPA. Nothing in this document shall be construed as superseding or being 

in conflict with any applicable regulations, statutes, or policies to which EPA is subject. •' 

4. Definition: 

Confidential Business Information - Information claimed by the provider to be 

confidential. This information may be identified with such titles as trade secret, secret, 

administrative secret, company secret, secret proprietary, privileged, administrative confidential, 

company confidential, confidential proprietary, or proprietary. NOTE: These markings should

Executive Order 11652. 

liT 
P.17 

5. Background 

Section 114 (c) ofthe Clean Air Act as amended reads as follows: 

"Any records, reports, or information obtained under subsection (a) shall be 

available to the public, except that upon a showing satisfactory to the 

Administrator by any person that records, reports, or information, or particular 

part thereof, (other than emission data) to wtiich the Administrator has access 

under this section if made public, would divulge methods or processes entitled to 

protection as trade secrets of such person, the Administrator shall consider such 

records, report, or information or particular portion thereof confidential in 

accordance with the purposes of Section 1905 of Title 18 ofthe United States 

Code, except that such record, report, or information may l>e disclosed to other 

officers, employees, or authorized representatives ofthe United States concerned 

with carrying out this Act or when relevant in any proceeding under this Act." 

The treatment of CBI by the U.S. EPA, including data obtained under Section 114 ofthe 

Clean Air Act, is governed by Title 40, Part 2, ofthe Code of Federal Regulations. These 

regulations require EPA offices to include a notice with each request for information to inform the 

business of: (1) its right to assert a claim of confidentiality covering part or all ofthe information, 

(2) the method for asserting a claim, and (3) the effect of-failure to assert a claim at time of 

submission. In addition, the regulations: (1) set forth procedures, for the safeguarding of 

confidential information; (2) contain provisions for providing confidential information to authorize 

representatives; (3) contain provisions for the release of infonnation to the Congress, Comptroller 

General, other Federal agencies, State and local governments, and Courts; (4) permit the 

disclosure of information within EPA to employees with an official need for the infonnation; and 

(5) prohibit wrongful use of such infonnation 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). 

6. Procedures: 

a. Request for Infonnation 

Each request for infonnation made under the provisions of Section 114(a) is signed by the 

Division Director. The request includes standard enclosure "EPA's Information Gathering 

Authority Under Section 114 ofthe Ctean Air Act," which was designed to meet the requirement 

of 40 CFR Part 2 discussed above. 

b. Receipt of CAA Confidential Business Information 

Upon receipt of information for which confidential treatment has been requested, the 

Office ofthe Director (OD) directs the logging ofthe material and the establishment of a 

\k 
P.18 

permanent file. If confidential treatment is requested, but is not specifically marked, the material 

will be stamped "Subject to Confidentiality Claim." If part ofthe material is claimed to be 

confidential, that portion is marked "Subject to Confidentiality Claim." In compliance with 

Sections 2.204 and 2.208 of 40 CFR Part 2, the Group Leader 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 

hs holder with a competitive advantage. If the information is clearly not confidential, the Group 

Leader prepares a letter for signature ofthe Division Director, ESD, to notify the business of this 

finding. If the information is possibly confidential, the Group Leader sends a memorandum to 

inform the OD, ESD, of this finding, gives a brief description ofthe 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 infonnation 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 CAA CBI 

is received from the owner via an authorized representative or a third p4*rty, the same procedure is 

followed, with the addition of clearly identifying the infonnation 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. 

c. Storage of CAA Confidential Business Information 

Folders, documents, or material containing CAA CBI (as defined) shall be secured, at a 

minimum, in a combination-locked cabinet. Nonnal procedure is to secure this information is 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 ofthe OD. 

Knowledge ofthe combinations ofthe locking devices is limited to the Document Control 

Officer (DCO) and the minimum number of persons required to effectively maintain normal 

business operations. Records ofthe locking device combination are stored elsewhere in 

conformance whh the requirements ofthe EPA Security Manual. 

Combinations ofthe locks are normally changed whenever a person with knowledge ofthe 

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 may be returned no later than 4:30 p.m. on the same 

day they are removed. The intended user must sign the CBI Control Record when the file is 

checked out. 
P.19 

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

must not be left unattended. The infonnation must not be disclosed to any non-authorized 

personnel. 

Storage procedures for CAA 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, 

notation is placed in the file indicating what information was transmitted, the date, and the 

recipient. The authorized representative returns a signed receipt ofthe DCO. 

d. Access to CAA Confidential Business Information 

Only authorized EPA employees may open a distribute CAA CBI. 

Only employees who require and are authorized access to CAA 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 managed by an authorized federal 

employee. Access to the information is limited to those persons having a need to know in 

performing their official duties. 

The Group Leader having primary interest in the CAA 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 CAA CBI are placed on 

the Clean Air Aa CBI access list, which indicates the "specific" CBI each person is permitted to 

see. The Access List is reviewed and updated periodically. 

Companies under contract to perform work for the 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 CAA 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 ofan EPA legal office, and (c) must 

return to EPA all copies ofthe infonnation (and any abstracts or excerpts therefrom) upon 

request or whenever the information is no longer required for the performance ofthe work. 

\ $ 
P.20 

(2) The authorized contractor designated as a representative must 

obtain a written agreement from each of its employees who will have access to the infonnation. 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 CAA 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 ofthe Director, ESD. 

Requests for CAA 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 Freedom of Infonnation Act 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. 

f t 

e. Use and Disclosure of CAA Confidential Business Information 

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

memoranda, etc., that become a part ofthe public domain, except as provided for in 40 CFR 2 

Subpart B. 

The CAA CBI may not be sumnrarized without the approval ofthe Group Leader 

responsible for the CAA CBI. Any authorized reproductions must be logged into the CAA CBI 

document tracking 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 CAA 

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 comment or review prior to publication except in 

such cases as described above (6.d.3) wherein CBI is expressly included. However, because 

'-A 
industrial-data-gathering visits, plant inspections, and source testing can involve inadvertent 

receipt of CAA CBI, it is the policy of OAQPS 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 infonnation received by EPA or its authorized representative during the visit or test. The 

report may be prepared by either EPA or its authorized representative. The draft of that report is 

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

A second copy ofthe draft trip report is 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 ofthe report, as marked by the responsible plant official, is 

received by EPA information designated confidential is placed in the CBI files as described 

above. The original draft ofthe trip report is edited to delete the confidential information and to 

accommodate technical changes, and the trip report is issued.
