Table 3 to Subpart VVVV of Part 63 - MACT Model Point Value Formulas for Open Molding Operations¹

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.
