SUBJECT:               Applicability of the Coal Tar Pitch Volatiles
                      Standard to Dust of Coal Tar Pitch
In response to your written inquiry of March 16, 1982, this memorandum reasserts the applicability of the coal tar pitch volatiles standard to coal tar pitch dust.

The constituents of coal tar pitch are chemical substances that are collected as they volatilize during the destructive distillation of coal to produce coke, which is the distillation residue of coal. This fact places the constituents under the coal tar pitch volatiles standard. It is irrelevant whether the constituents are in solid, liquid, or gaseous form.
