Where:
AT = 24-hour average concentration of resin type T, parts per million by weight (dry basis).
PGi = Production of resin grade Gi, pounds.
CGi = 24-hour average concentration of vinyl chloride or total non-vinyl chloride organic HAP in resin grade Gi, ppmw.
QT = Total production of resin type T over the 24-hour sampling period, pounds.
Where:
CTNVCH = Concentration of total non-vinyl chloride organic HAP compounds in the stripped resin sample, in parts per million by weight (ppmw).
Ci = Concentration of individual HAP present in the stripped resin sample analyzed pursuant to paragraphs (b)(1)(i) and (b)(1)(ii) of this section excluding vinyl chloride, in ppmw, where a value of zero should be used for any HAP concentration that is below the detection limit.
