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—
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.
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
