aVessel capacity and vapor pressure criteria are specific to the listed chemical, to “all chemicals,” or to “all other chemicals,” as indicated.
bMaximum true vapor pressure of total organic HAP at storage temperature.
cThe applicability criteria in Table 4 of this subpart shall be used for chemicals not specifically listed in this table (i.e., Table 5).
dThe control level for the first two sets of applicability criteria are specified in 63.1314 as 90% and 98%, respectively. The control level for the third set of applicability criteria is the HON control level of 95%.
