2005 AIR EMISSIONS INVENTORY
SITEWIDE LABORATORY AND OTHER NON -MANUFACTURING
HAP/TAP EMISSIONS
The basis for the determination of the TAP and HAP emissions from the various sitewide
quality control and research laboratories, which are exempted from permitting under
NCAC Title 15A 2Q.0102(b)(1)(C), or other non -manufacturing usage (such as chlorine
for drinking water disinfection), is the simplified approach whereby the total quantity of a
TAP/HAP chemical purchased during the year for laboratory or non -manufacturing usage
is assumed to have volatilized and is therefore shown as an air emission.
Obviously this is an overstatement of the actual air emissions, but given the small
quantity of the laboratory chemicals or other non -manufacturing usage, and the difficult
task of determining actual emissions, this approach was chosen.
