MEMORANDUM FOR: DAVID H. RHONE
THRU: JOHN B. MILES

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.
