This analysis was carried out using only point source information (as area sources are not relevant in this context). Although some of the VOC species included in the above analysis are already individually listed on the NPRI, the triggering thresholds for individual reporting have no affect on the analysis, since the VOC speciation requirement would be independent of reporting requirements for individually-listed VOC.
VOC species for a facility were included or excluded in the estimates based on whether they were on the list at 90% and 80% coverage respectively, and whether they met the release de-minimus threshold. The percent coverage calculation includes the national sum of the species mass (or reactivity) for the species listed, divided by the national point source VOC emissions total.
