Dear Mr. Kery: 

Midwest Research Institute (MRI) is currently under contract 

(Contract No. 68-02-3817) with the U. S. Environmental Protection Agency 

(EPA) to study air emissions of chromium from several different source 

categories including chromium plating operations. As noted in Enclosure 1, 

MRI has been designated as an authorized representative of EPA to perform 

this study under Section 112 of the Clean Air Act. 

In our telephone conversation on February 19, 1985, I explained 

that we are presently collecting information on chromium plating processes 

and emission control techniques and that we are interested in visiting 

your plating facility in Livonia, Michigan. I will be contacting you 

again within the next week to discuss this. The information you provide 

will be used in deciding whether or not to proceed with the development 

of an air emission standard for chromium plating operations. 

We appreciate any assistance you can give us in this matter. If 

you have any questions, please contact me at (919) 781-5750. 

Sincerely, 

Barbara W. Duletsky 

Environmental Engineer
