'or cause other environmental impacts. Specifically, the .District Board 

has established a policy to phase out chlorofluorocarbons (CFCs), methyl 

chloroform (1,1,1-trichloroethane or TCA), and carbon tetrachloride by 

December 31,1995. 

FIRE RETARDANT MATERIALS are polyester resin materials used to 

make products that are resistant to flame or fire. 

GEL COAT is a polyester resin surface coating, either pigmented or 

clear, that provides a cosmetic enhancement and improves resistance to 

degradation from exposure to the elements. 

GENERAL PURPOSE POLYESTER RESINS are materials that are 

not corrosion resistant, fire retardaiit, high strength, vapor suppressed, or 

gel coats. 

HIGH-STRENGTH MATERIALS are polyester resins which have 

casting tensile strength of 10,000 psi or more and which are used for 

manufacturing of high performance boats and skis. • 

HIGH-VOLUME, LOW-PRESSURE. (HVLP) SPRAY is a coating 

application system which is operated at air pressure of between 0.1 and 

10 pounds per square inch gauge (psig) at the air cap of the spray gun.

(10) MONOMER is a relatively low-molecular-weight organic compound such 

. as styrene that combines with itself, or other similar compounds, by a

(11) POLYESTER RESIN MATERIALS are unsaturated polyester resins, 

such as isophthalic, orthophthalic, halogenated, bisphenol A, vinyl ester, 

or furan resins; cross-linking agents; catalysts; gel coats; inhibitors; 

accelerators; promoters; and any other material containing VOC used ln 

polyester resin operations. 

(12) POLYESTER RESIN OPERATIONS fabricate, rework, repair, or 

touch-up products for commercial, military, or industrial use by mixing, 

pouring, hand laying-up, impregnating, injecting, forming, winding, 

spraying, and/or curing by using unsaturated polyester resin materials. 

(13) PULTRUSION is a process where continuous roving strands are moved 

through a strand-tensioning device into a resin bath for impregnation and 

then passed through a heated die for curing. 

(14) REPAIR is that portion of the fabrication process that requires the 

addition of polyester resin materials to portions of a previously fabricated 

product in order to mend damage. 

(15) TOUCH-UP is that portion of the process that is necessary to cover 

minor imperfections. 

(16) VAPOR SUPPRESSED RESIN is a polyester resin material which 

contains additives to reduce VOC evaporation loss to less than sixty (60) 

grams per square meter of surface area as determined and certified by 

resin manufacturers. 

(17) VOLATILE ORGANIC COMPOUND (VOQ means any volatile 

chemical compound that contains the element carbon, excluding 

methane, carbon monoxide, carbon dioxide, carbonic acid, metallic 

carbides and carbonates, ammonium carbonate, and exempt compounds. 

(c) Requirements 

(1) For each process, a person operating a polyester resin operation shall
