This brochure provides an overview of the U. S.
Environmental Protection Agency’s (EPA) air toxics
and criteria emission estimating tools EPA
develops air emission inventory tools for point and
area sources to support many activities, including:
Clean Air Act requirements, State Implementation
Plans (SIP), SARA 313 reporting requirements,
and other emission estimating and assessment
activities. Most of these tools are developed and
maintained by the Emission Factor and Inventory
Group (EFIG) within EPNs Office of Air Quality
Planning and Standards (OAQPS).
This brochure describes each tool and its intended
use. Users should select the tool(s) best suited to
their projects and obtain the reports or computer
databases necessary. For further information on
any of these tools, call Info CHIEF at (919) 541-
528 5, or write:

These estimating tools should be used with
discretion. Actual emissions from individual sources
may vary considerably from values estimated by
using emission and speciation factors Source-
specific emission test data are generally preferred,
when available ERG welcomes any emission data
that would help improve the emissions estimating
tools presented in this brochure.

42 is the recommended source ofair pollutiuit emission factors
for both criteria and toxic emissions. AP-42 Volume I
addresses hundreds of stationary, point, and area sources
and Volume II deals ith mobile sources. EPA emission
rates for mans polluting activities are obtained from source
tests, material balance studies, and engineering estunates and
then collected. appioved. and compiled into the AP-42
document. AP-42 is available on the (‘I/JET website and
from GPO, Sto’;k No. O 5-OOO-OO5OO-l.
The Emission luvcntorv Improvement Program (EflP is a
joint program 01 the EPA, SAEWG, and STAPPA/ALAPCO.
The ultimate goal of the EIIP is to provide cost-effective,
reliable inventories by improving the quality of emissions
data collected ai d provide for uniform reporting of this intbr-
ination. Their findings arc available in a seven volume set ol
guidance reports, which are available on the EIIP website and
from FF 16. For more information, call Info ChIEF.
