M[i] = the mass of open molding resin or gel coat, i, purchased in the past 12 months in an operation, in megagrams;
VOC[i] = the monomer VOC content, in percent by weight, of open molding resin or gel coat, i, purchased in the past 12 months in an operation; and
n = the number of different open molding resins or gel coats purchased in the past 12 months in an operation;
EQUATION 14B:
FSMVEL = 46(M[R]) + 159(M[PG]) + 291(M[CG]) + 54(M[TR]) + 214(M[TG])
Where:
FSMVEL (facility-specific monomer VOC emission limit) = the total allowable monomer VOC that can be emitted from an open molding resin and gel coat operation included in the average, in kilograms per 12-month period;
M[R] = the mass, in megagrams, of production resin purchased in the past 12 months, excluding materials exempted in (c) above;
M[PG] = the mass, in megagrams, of pigmented gel coat purchased in the past 12 months, excluding materials exempted in (c) above;
M[CG] = the mass, in megagrams, of clear gel coat purchased in the past 12 months, excluding materials exempted in (c) above;

M[TG] = the mass, in megagrams, of tooling gel coat purchased in the past 12 months, excluding materials exempted in (c) above; and
The numerical coefficient associated with each term on the right-hand side of Equation 14B is the allowable monomer VOC emission rate for that material in units of kilograms of monomer of VOC per megagram of material purchased. For example, "46" means 46 kilograms (kg) of monomer VOC per megagram (Mg) of resin purchased.

As shown in Equation 14D, PVOP equals the sum of the products of M[i] and PV[i] for open molding resin or gel coats, one through n, divided by M[i] one through n;
n = the number of different open molding resins and gel coats purchased within an operation in the past 12 months;
M[i] = the mass of resin or gel coat, i, purchased within an operation in the past 12 months, in megagrams; and
PV[i] = the monomer VOC emission rate for resin or gel coat, i, purchased within an operation in the past 12 months, in kilograms of monomer VOC per megagram of material applied. PV[i] is computed using the equations in Table 14B.

As shown in Equation 14E, PV[F] shall be equal to 100 minus the weight-percent of filler, divided by 100, with the entire quantity multiplied by PV[U];
PV[U] = the monomer VOC emission rate for the neat (unfilled) resin, before filler is added, as calculated using the formulas in Table 14B, per 12-month period, based on monthly purchase records; and
