Mr. James Kotagides 

President 

Olymco, Incorporated 

2215 Harrison Avenue, S.W. 

Canton, Ohio 47706 

Dear Mr. Kotagides: 

As you may know, the United States Environmental Protection Agency 

(EPA) is considering adding chromium to the list of hazardous air pollutants 

under Section 112 of the Clean Air Act, as amended, August 1977. A 

preliminary assessment has identified 11 categories of stationary sources 

as potential emitters of significant quantities of chromium to the 

atmosphere. Included among these source categories is chromium electroplating. Because the preliminary assessment was based on limited data 

and available information, especially with respect to the quantities and 

forms of chromium actually emitted, EPA has undertaken a program to 

develop additional background information on all 11 source categories. 

This information will be used to determine the need for standards for 

each source category. 

We are requesting that Olymco, Incorporated provide information on 

processes, emission levels, and emission control for its facility in 

Canton, Ohio. The specific information requested is itemized in 

Enclosure 1. This information, along with similar information from 

other companies, will be used to assess the significance of chromium 

emissions from the chromium electroplating 

to the amount of labor required to respond 

tried to limit it to information necessary 

of emission control. Also, you may merely 

questions that do not apply to your plant. 

industry. We are sensitive 

to this request and have 

to define the current status 

respond "not applicable" to 

The authority for EPA's information gathering is included in 

Section 114 of the Clean Air Act, as amended (42 U.S.C. 7414). Enclosure 

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 pieces of information. Please do not 

label an entire response "confidential" if only certain portions consist 

of trade secret information. Refer to Enclosure 2 for the information 

EPA may require, at a later time, to support your confidentiality claims. 

Any information determined to constitute a trade secret will be protected 

/• 
P.3 

under 18 U.S.C. 1905. If no claim of confidentiality accompanies the 

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

public by EPA without further notice (40 CFR Part 2.203, September 1, 

1976). All emission data, however, will be available to the public. It 

will simplify handling procedures if you would separate specific items 

claimed to be confidential from the balance of the data. 

The EPA has contracted with Midwest Research Institute (MRI) (Contract 

No. 68-02-3817) to obtain information pertinent to the industry. Thus, 

as noted in Enclosure 3, MRI has been designated by EPA as an authorized 

representative of the Agency. Therefore, MRI has the rights discussed 

above and in Enclosure 2. As a designated representative of the Agency, 

MRI is subject to the provisions of 42 U.S.C. 7414(c), respecting 

confidentiality of methods or processes entitled to protection as trade 

secrets. 

Enclosure 4 summarizes Agency and Emission Standards and Engineering 

Division policies and procedures for handling privileged information and 

describes EPA contractor commitments and procedures for use of confidential 

materials. It is 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. 

If you have any questions regarding this request or are unable to 

provide me with responses to the enclosed questions by August 12, 1985, 

please contact Mr. Al Vervaert or Mr. James Crowder, of the Industrial 

Studies Branch, at (919) 541-5601. 

Sincerely, 

Jack R. Farmer 

Director 

Emission Standards and 

Engineering Division
