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 |
| 1 Equations 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. |
