Where:
AT = 24-hour average concentration of type T resin in ppm (dry weight basis).
QT = Total production of type T resin over the 24-hour period, in kg (ton).
T = Type of resin.
MGi = Concentration of vinyl chloride in one sample of grade Gi resin in ppm.
PGi = Production of grade Gi resin represented by the sample, in kg (ton).
Gi = Grade of resin: e.g., G1, G2, G3.
n = Total number of grades of resin produced during the 24-hour period.
The number of 24-hour average concentrations for each resin type determined during the reporting period shall be reported. If no 24-hour average resin vinyl chloride concentrations in excess of the limits prescribed in § 61.64(e) are measured, the report shall state that no excess resin vinyl chloride concentrations were measured.
For each type of resin (suspension, dispersion, latex, bulk, other), the following calculation is to be performed:
Where:
AT = 24-hour average combined reactor opening loss and emissions from all sources following the reactor used as a stripper, in g vinyl chloride/kg (lb/ton) product (dry weight basis).
QT = Total production of resin in batches for which stripping is completed during the 24-hour period, in kg (ton).
T = Type of resin.
CGi = Average combined reactor opening loss and emissions from all sources following the reactor used as a stripper of all batches of grade Gi resin for which stripping is completed during the 24-hour period, in g vinyl chloride/kg (lb/ton) product (dry weight basis) (determined according to procedure prescribed in § 61.67(g)(6) ).
PGi = Production of grade Gi resin in the batches for which C is determined, in kg (ton).
Gi = Grade of resin: e.g., G1, G2, G3.
n = Total number of grades of resin in batches for which stripping is completed during the 24-hour period.
The number of 24-hour average emissions determined during the reporting period shall be reported. If no 24-hour average combined reactor opening loss and emissions from all sources following the reactor used as a stripper in excess of the limits prescribed in § 61.64(f) are determined, the report shall state that no excess vinyl chloride emissions were determined.
