1 open molding resin and gel coat operations (including pigmented gel coat, clear gel coat, production resin, tooling gel coat and tooling resin;

2 resins and gel coat mixing operations; and

3 resins and gel coat application equipment and cleaning operations.

The owner or operator of a facility that solely manufactures fiberglass parts of boats, such as hatches, seats or boat trailers is not subject to this Chapter.

C.This regulation does not apply to the following activities:

1 The application of surface coatings applied to fiberglass boats;

2 The application of surface coatings for fiberglass and metal recreational boats (pleasure craft); and

1 Production resins (including skin coat resins) that meet the specification for use in military vessels or are approved by the U.S. Coast Guard for use in the construction of lifeboats, rescue boats, and other life saving appliances approved under 46 CFR Subchapter Q, or the construction of small passenger vessels regulated by 46 CFR Subchapter T, including but not limited to vessels of less than 100 tons carrying more than 6 and less than 150 passengers for hire. Production resins that meet these criteria must be applied with nonatomizing resin application equipment in order to qualify for exemption under this subsection;

2 Pigmented, clear, and tooling gel coat used for part or mold repair and touch-up. The total gel coat materials included in this exemption must not exceed 1.0 (one) percent by weight of all resin and gel coat used at a facility on a 12-month rolling average basis;

3 Pure, 100 percent vinylester resin used for skin coats that are applied with nonatomizing resin application equipment and with the total amount of the resin materials not exceeding five percent by weight of all resin used at a facility on a 12 month rolling average basis. This exemption does not apply to blends of vinylester and polyester used for skin coats; and

4 Any closed molding operation as defined by this Chapter. Open molding resin and gel coat operations such as gel coat or skin coat layers that precede a closed molding operation are not exempt.
