Thank you for providing mformation on gel coat properties and chemistry during our 

telephone conversation on July 8, 1998. The EPA and its contractor, Pacific Environmental 

Services, Inc., are in the process of collecting gel coat property and cost data that will be used in 

developing the maximum achievable control technology (MACT) standard for the plastic composites 

industry pursuant to Section 112 ofthe Clean Air Act, as .amended in 1990. 

We would like to collect data on the properties and costs for gel coats sold by Cook 

Composites and Polymers in order to assess the costs that facilities would incur by switching fiom 

gel coats with a high hazardous air pollutant (HAP) content to a low HAP content. Based on our 

assessment, the following HAP contents are considered low: (1) 30 percent or less HAP for 

pigmented production gel coats, (2) 40 percent or less HAP for clear production gel coats, and (3) 

40 percent or less HAP for tooling gel coats. We would appreciate if you would provide information 

on properties and costs for the gel coats shown in Enclosure 1. In addition, we would like you to 

identify low HAP replacements that Cook Composites and Polymers sells for high HAP pigmented, 

clear, and tooling gel coats. When you select these high and low HAP gel coat pairs, we would like 

you to match the gel coat properties for each ofthe pairs as closely as possible and provide average 

list costs for each pair. Please provide as many of these gel coat pairs as possible for each ofthe 

three gel coat applications (pigmented production, clear production, and tooling). The costs for these 

resin pairs identified by Cook Composites and Polymers can be added to the table in Enclosure 1. 

If any ofthe information you submit in response to the list of questions in Enclosure 1 is 

considered by your company to be confidential business information (CBI), please indicate those 

portions of your response considered to be CBI and mail the entire response to: 

WASHINQTON, D.C. • RESEARCH TRIANQLE PARK. NC • LOS ANQELES. CA • CINCINNATI, OH

be CBI, please submit the response directly to me either through the mail or through our fax number
