40 CFR Appendix Table 3 to Subpart VVVV of Part 63, MACT Model Point Value Formulas for Open Molding Operations 1

Table 3 to Subpart VVVV of Part 63 - MACT Model Point Value Formulas for Open Molding Operations 1

As specified in §§ 63.5710(d) and 63.5714(a), you must calculate point values using the formulas in the following table:

For this operation - And this application method - Use this formula to calculate the MACT model plant value for each resin and gel coat -
1. Production resin, tooling resin a. Atomized 0.014 × (Resin HAP%) 2.425
b. Atomized, plus vacuum bagging with roll-out 0.01185 × (Resin HAP%) 2.425
c. Atomized, plus vacuum bagging without roll-out 0.00945 × (Resin HAP%) 2.425
d. Nonatomized 0.014 × (Resin HAP%) 2.275
e. Nonatomized, plus vaccum bagging with roll-out 0.0110 × (Resin HAP%) 2.275
f. Nonatomized, plus vacuum bagging without roll-out 0.0076 × (Resin HAP%) 2.275
2. Pigmented gel coat, clear gel coat, tooling gel coat All methods 0.445 × (Gel coat HAP%) 1.675

1Equations calculate MACT model point value in kilograms of organic HAP per megagrams of resin or gel coat applied. The equations for vacuum bagging with roll-out are applicable when a facility rolls out the applied resin and fabric prior to applying the vacuum bagging materials. The equations for vacuum bagging without roll-out are applicable when a facility applies the vacuum bagging materials immediately after resin application without rolling out the resin and fabric. HAP% = organic HAP content as supplied, expressed as a weight-percent value between 0 and 100 percent.
