Applicability. This regulation applies to reinforced plastic manufacturing at a premises where the total actual VOC emissions from all reinforced plastic manufacturing including tooling, touch-up, and repair is 20 pounds or more per day. The requirements in this regulation do not apply to polyester resins used for tooling or touch-up and repair. The requirements in this regulation do not apply to any fiberglass boat manufacturing facility as defined in Regulation .26-1B(5) of this chapter. Definitions. In this regulation, the following terms have the meanings indicated: “Clean-up material” means any material used in reinforced plastic manufacturing to clean parts, tools, equipment, and work areas. “Low styrene resin” means a polyester resin that has a monomer content of 35 percent or less by weight as applied. “Monomer” means a low molecular weight organic compound that reacts with itself or other similar compounds to produce a polyester resin. “Non-VOC cleanup material” means a material that is used to clean products, tools, process equipment, and other equipment used in the manufacture of reinforced plastic products and contains less than 5 percent VOC by weight or a material that has a VOC partial pressure not exceeding 0.74 pound per square inch. “Polyester resin (resin)” means a mixture of true esters dissolved in a polymerizable monomer such as styrene. “Reinforced plastic manufacturing” means the curing of polyester resins with fiberglass, inert fillers, or other reinforcement materials. “Specialty resin” means a polyester resin used in special applications involving high strength, corrosion resistance, fire resistance, or gel coat. “Tooling” means the production of molding tools such as shapes, matrixes, molds, or other instruments and utensils that are used during reinforced plastic manufacturing. “Touch-up and repair” means small quantity use of polyester resin to repair minor surface damage or imperfections, where the total polyester resin used is less than 1 percent of the total quarterly polyester resin used as reported in §D(1) of this regulation. Requirements. Except as provided in §C(3) of this regulation, a person subject to this regulation with actual VOC emissions of 20 pounds or more per day shall use low styrene resins. A person subject to this regulation with actual VOC emissions of 100 pounds or more per day shall also use an improved application method such as: An airless or air-assisted airless spray gun; A low pressure nozzle; A pressure-fed roller or flow coater; or Some other nonatomized resin application technique. A person subject to this regulation who uses a specialty resin may not use a specialty resin with a monomer content exceeding 50 percent by weight as applied. A person subject to this regulation shall use non-VOC cleanup materials. Record Keeping. A person subject to this regulation shall maintain records that provide the following information: A description of each polyester resin material used; and The total weight and VOC content of each polyester resin material used quarterly. Records shall be maintained for not less than 3 years and made available to the Department upon request.
