1998 AIR EMISSIONS INVENTORY
SITEWIDE LABORATORY 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), is the simplified approach whereby the total quantity
of a TAP/HAP chemical purchased during.1998 for laboratory 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 and the difficult task of determining actual
emissions, this approach was chosen.
