Table 1 provides
the complete list of toxic air contaminants and ozone depleters on Form TACS
including TAC Code, TAC group name, CAS#, and the name of each specific substances
classified under each TAC group. The last column “Type of TAC/ODC” identifies
each of the listed components as VOC or PM.
Table 1 lists the family name and the individual species
within the family for the following toxic air contaminants (TACs):
§
Chlorinated dioxins and dibenzofurans (TAC code #7)
§
Fluorocarbons (chlorinated and brominated) (TAC code
#22)
§
PAHs (TAC code #19)
It is important when reporting emissions for these
families of compounds that emissions are not double-counted thus adversely
affecting the facility’s emissions and/or fees. Emissions reported for the overall family and each of the species
within the family are summed for the purpose of calculating total facility
emissions and/or assigning fees and prioritizing facility risks. Therefore, it is important that you either
report emissions by individual species or overall emissions for the toxic
family. It is always preferable to
report emissions by individual species if that information is available. Table 2 considers each toxic family and
several other toxics such as, arsenic (CAS #7440382), asbestos (CAS #1332214),
hexavalent chromium (CAS #18540299), lead (CAS #7439921), and nickel (CAS
#7440020), and provides recommendations for emissions reporting. All TAC emissions must be reported on form
TAC as well as on form TACS. It is
important that the directions provided in Table 2 be read carefully before
calculating TAC emissions.
