EPA AIR DOCKET 

Contact Summary: 

Ms. Marie Birgitta was contacted on behalf of the U.S. EPA to update information provided 

in the 1993 EPA Reinforced Plastic Composites Screening Survey submitted by William Kreysler 

& Associates, Inc. for their facility located in Petaluma, California. In response to my questions Ms. 

Birgitta indicated the following: 

The facility uses hand lay-up to apply a polyester tooling resin in the fabrication of molds. 

The polyester tooling resin applied by hand lay-up contains approximately 33.6% HAP by weight. 

The only HAP initially present in the resin is styrene. No additional HAP is added to the resin 

applied using the hand lay-up fabrication process with the exception of small amounts of HAP that 

may (or may not) be present in initiators, promoters and/or catalysts added to the resins. The resin 

applied by hand lay-up does not contain a vapor suppressant. 

The facility uses spray lay-up to apply a fire-retardant polyester resin in the fabrication of 

sculptures and architectural ornaments. The polyester resin applied by spray lay-up in the fabrication 

of sculpture? and architectural ornaments contains approximately 37.1% HAP by weight. 

The facility has recently used spray lay-up to apply a polyester resin in the fabrication of 

underground oil pits. While the facility does not currently manufacture these underground oil pits, 

it expects to do so again in the future. These oil pits are primarily used to capture recycled oil at 

service stations and businesses that specialize in quick oil changes. The polyester resin applied by 

spray lay-up in the production of these underground oil pits contains approximately 33.6% HAP by 

weight. 

The only HAP initially present in the resins applied using spray lay-up is styrene. No 

additional HAP is added to the resins applied using the spray lay-up fabrication process with the 

exception of small amounts of RAP mat may (or may not) be present in initiators, promoters and/or 

catalysts added to the resins. The resins appUed by spray lay-up do not contain vapor suppressants. 

The facility uses hand lay-up and spray lay-up to apply white and neutral polyester gel coats. 

The neutral gel coat and the white gel coat constitute approximately 55% and 45% (by weight) of 

the total amount of gel coat used by the facility, respectively. Approximately 5% (by weight) of the 

gel coats used by the facility are applied using hand lay-up. The remaining 95% (by weight) of the 

gel coats are applied using spray lay-up. The white gel coat contains approximately 35.4% HAP 

(31.4% styrene, 4.0% methyl methacrylate). The neutral gel coat contains approximately 42.2% 

HAP (37.2% styrene, 5.0% methyl methacrylate). No additional HAP is added to the gel coats 

during the fabrication process with the exception of small amounts of HAP that may (or may not) 

be present in initiators, promoters and/or catalysts added to. the gel coats. ,
