Glas-Pro Division Fiberglass Molding Facility Facility ID: 5700 Section 31, T3S, R7W, Jefferson County, Oklahoma Latitude: 34.24749° Longitude: -97.96698° Location: 100 W. Eva, Addington, Oklahoma 73520 I. INTRODUCTION Elliott Manufactured Homes, Inc. (Elliott) has requested to renew their existing major source Operating Permit No. 2012-1199-TVR that was issued November 26, 2013, for their existing Fiberglass Molding Facility (SIC 3088). No changes have been made to the facility since the issuance of last permit (No. 2012-1199-TVR). The applicant has been manufacturing shower tubs and stalls since before March 6, 1996. Elliott manufactures fiberglass shower tubs, stalls and other related products for use in the manufactured and residential home building industry. Units are manufactured utilizing an open mold process. Hazardous air pollutants (HAPs) are generated and released from the fabrication process. The primary HAP generated from the facility is styrene, which is generated from the gelcoats and resins used in the fabrication processes. Particulate matter (PM) is generated during the sanding and finishing process and is filtered prior to air being exhausted to the outside. The applicant requests that a 75 TPY facility-wide Hazardous Air Pollutants cap continue as the facility emission limit.
