Except as specified in Env-A 1219.05, the owner or operator of a fiberglass boat manufacturing facility subject to this part shall limit VOC emissions from molding operations other than closed molding by one or more of the following control options:
(a) Control option 1 shall consist of using resins and gel coats that meet the applicable individual monomer VOC content limits as specified in table 1219-1, below: Table 1219-1 Compliant Materials Monomer VOC Content Limits for Open Molding Resin and Gel Coat
Material Used | Application Method | Weighted Average Monomer VOC Content Limit (in weight percent) |
Production resin | Atomized (spray) | 28 |
Production resin | Nonatomized | 35 |
Pigmented gel coat | Any method | 33 |
Clear gel coat | Any method | 48 |
Tooling resin | Atomized | 30 |
Tooling resin | Nonatomized | 39 |
Tooling gel coat | Any method | 40 |
(b) Control option 2 shall consist of using resins and gel coats of a certain type that meet the applicable monomer VOC content limit for a specific application method specified in table 1219-1, above, on a 12-month weighted-average basis, as calculated using the following formula: (1) "Mi" means the mass of open molding resin or gel coat i used in the past 12 consecutive months in an operation, in megagrams;(2) "VOCi" means monomer VOC content, by weight percent, of open molding resin or gel coat i used in the past 12 consecutive months in an operation; (3) "n" means number of different open molding resins or gel coats used in the past 12 consecutive months in an operation; and (4) The weighted average monomer VOC content shall equal the sum of the products of Mi and VOCi for open molding resin or gel coats one through n, divided by Mi one through n, as in the following equation: Click here to view image
Weighted average monomer VOC content =
(c) Control option 3 shall consist of meeting a facility-specific monomer VOC mass emission limit on a consecutive 12-month period that is determined using the formulas specified in Env-A 1219.03; or(d) Control option 4 shall consist of using add-on controls to achieve a numerical monomer VOC emission limit that is determined for each facility in accordance with the equation in Env-A 1219.03(a), based on the mix of application methods and materials used at that facility, except that instead of using the mass of each material used over the past 12 consecutive months, the facility shall use the mass of each material used during the control device performance test.N.H.
