Current through Register Vol. 56, No. 24, December 18, 2024

Section 7:27-16.14 - Fiberglass boat manufacturing materials

(a) Except as provided at (b) below, this section applies to any fiberglass boat manufacturing facility whose total actual VOC emissions, before add-on controls, exceed 15 pounds per day from all fiberglass boat manufacturing operations, calculated as follows:

1. Include in the calculation of the 15 pounds per day limit any emissions from:

i. Open molding resin and gel coat operations;

ii. Resin and gel coat mixing operations;

iii. Resin and gel coat application equipment cleaning operations; and

iv. Polyester resin putty used to assemble fiberglass parts.

2. Exclude from the calculation of the 15 pounds per day limit any emissions from:

i. Surface coating formulation applied to fiberglass boats or pleasure crafts; and

ii. Industrial adhesive used in the assembly of fiberglass boats, other than a polyester resin putty used to assemble fiberglass parts.

(b) A fiberglass boat manufacturing facility is exempt from this section if it manufactures only boat trailers, or parts of boats, such as hatches, seats, or lockers, and does not manufacture boat hulls or decks from fiberglass or build molds to make fiberglass boat hulls or decks.

(c) The following materials and operations are exempt from (d) and (e) below:

1. Production resin that is applied with nonatomized resin application equipment, and that:

i. Must meet specifications for use in military vessels;

ii. The U.S. Coast Guard must approve in accordance with 46 CFR Subchapter Q, Equipment, Construction, and Materials: Specifications and Approval, for use in the construction of lifeboats, rescue boats, and other life-saving appliances; or

iii. The U.S. Coast Guard must approve for use in the construction of small passenger vessels regulated by 46 CFR Subchapter T, Small Passenger Vessels (Under 100 Gross Tons);

2. Production or tooling resin, or a pigmented, clear, or tooling gel coat purchased for repair or touch-up of fiberglass parts or molds. The total amount of resin and gel coat material exempted from (d) and (e) below shall not exceed one percent by weight of all resin and gel coat purchased at the facility on a 12-month rolling average basis;

3. One hundred percent pure vinylester resin (not a blend of vinylester and polyester), purchased for use as a skin coat and applied with nonatomized resin application equipment, where the total amount of the 100 percent pure vinylester resin purchased does not exceed five percent of all resin purchased at the facility on a 12-month rolling average basis;

4. Surface coating formulation applied to fiberglass boats or pleasure crafts;

5. Industrial adhesive used in the assembly of fiberglass boats, with the exception of polyester resin putty used to assemble fiberglass parts; and

6. Closed molding operations. This exemption does not apply to an open molding resin and gel coat operation that precedes a closed molding operation, such as the application of a gel coat or skin coat layer.

(d) Except as provided at (c) above, the owner or operator of any open molding resin and gel coat operation at any fiberglass boat manufacturing facility to which this section applies shall ensure (d)1, 2, or 3 below. For compliance determination, any non-monomer VOC content of a resin or gel coat in excess of five percent shall be added to the monomer VOC content.

1. The monomer VOC content (percent by weight) in any resin or gel coat purchased for any open molding resin and gel coat operation, or purchased for any other molding operation that is not a closed molding operation, such as a vacuum bagging operation, does not exceed:

i. The maximum monomer VOC content (percent by weight) limit for the material and application method listed in Table 14A; or

ii. The weighted average monomer VOC content (percent by weight) limit as determined by Equation 14A for the material and application method listed in Table 14A.

VOC[i] = the monomer VOC content, in percent by weight, of open molding resin or gel coat, i, purchased in the past 12 months in an operation; and

n = the number of different open molding resins or gel coats purchased in the past 12 months in an operation;

2. The VOC emissions from each open molding resin and gel coat operation, and from any other molding operation that is not a closed molding operation, such as a vacuum bagging operation, do not exceed a facility-specific monomer VOC emission limit established pursuant to (d)2i through iii below, per 12-month period, of the mass of each material purchased, as follows:

i. Use Equation 14B to establish the facility-specific monomer VOC emission limit;

ii. For any open molding resin and gel coat operation included in Equation 14B, use Equation 14C to demonstrate that the monomer VOC mass emissions from the operation do not exceed the facility-specific monomer VOC emission limit calculated using Equation 14B for the same 12-month period. Conduct this demonstration at the end of the first 12-month period and at the end of every subsequent month for only those operations and materials included in the average; and

iii. For each open molding resin and gel coat operation included in Equation 14B, use Equation 14D to compute the weighted-average monomer VOC emission rate per 12-month period for each open molding resin and gel coat operation included in the average for use in Equation 14C; or

3. A VOC control apparatus installed to control the VOC emissions from an open molding resin operation, or gel coat, prevents VOC emissions from exceeding the maximum facility-specific monomer VOC mass emission limit established using Equation 14B in accordance with (d)2i above.

EQUATION 14B:

FSMVEL = 46(M[R]) + 159(M[PG]) + 291(M[CG]) + 54(M[TR]) + 214(M[TG])

Where:

The numerical coefficient associated with each term on the right-hand side of Equation 14B is the allowable monomer VOC emission rate for that material in units of kilograms of monomer of VOC per megagram of material purchased. For example, "46" means 46 kilograms (kg) of monomer VOC per megagram (Mg) of resin purchased.

As shown in Equation 14D, PVOP equals the sum of the products of M[i] and PV[i] for open molding resin or gel coats, one through n, divided by M[i] one through n;

n = the number of different open molding resins and gel coats purchased within an operation in the past 12 months;
