USEPA Technology Transfer Network
The Technology Transfer Network
(TTN) is a collection of technical Web sites containing information
about many areas of air pollution science, technology, regulation,
measurement, and prevention. In addition, the TTN serves as a public
forum for the exchange of technical information and ideas among
participants and EPA staff.
USEPA CHIEF (Clearinghouse for
Inventories and Emission Factors)
CHIEF is a collection of pages
dealing with information on emission inventories, emission factors
and emission modelling. The site also contains software that is
useful to calculate emissions.
The Emission Factor and Inventory
Group (EFIG) of the Office of Air Quality Planning and Standards
(OAQPS) of USEPA develops and maintains emission estimating tools to
support many activities. The AP-42 series is the principal means by
which EFIG documents its emission factors. AP-42 contains process
details and supporting reference material for the factors.
USEPA Emission Inventory
The Emission Inventory Improvement
Program (EIIP) is a jointly sponsored effort of the State and
Territorial Air Pollution Program Administrators/Association of Local
Air Pollution Control Officials (STAPPA/ALAPCO) and EPA, and is an
outgrowth of the Standing Air Emissions Work Group (SAEWG). Funding
is provided by state/local agencies through the federal 105 grant
programs. The EIIP Steering Committee and technical committees are
composed of state, local, industry, and EPA representatives.
Membership on technical committees is open to any state or local
agency representative, industry group, and the public; interested
individuals should contact the appropriate committee cochair for information.
USEPA AIRS Database
The goal of EIIP is to provide
cost-effective, reliable inventories by:
Improving the quality of emissions
Developing system(s) for
collecting, calculating, and reporting emissions data
AIRS (Aerometric Information
Retrieval System) is a computer-based repository of information about
airborne pollution in the United States and various World Health
Organization (WHO) member countries. The system is administered by
the U.S. Environmental Protection Agency (EPA), Office of Air Quality
Planning and Standards (OAQPS), Information Transfer and Program
Integration Division (ITPID), located in Research Triangle Park,
North Carolina. AIRS is installed on the IBM computer system at the
EPA's National Computer Center (NCC) in Research Triangle Park, North Carolina.
Emission Estimation Software
Please note: The software that
follows was developed by USEPA and not the Illinois EPA. Questions
regarding the installation, use or identification of errors should be
addressed to the appropriate staff at USEPA as indicated in the
Information REtrieval (FIRE)
The FIRE Data System is a database
containing EPA's recommended emission estimation factors for criteria
and hazardous air pollutants. FIRE requires an IBM-compatible PC
running Windows 95/98 or NT with at least 32 MB of available hard
disk space to install and run.
TANKS is a Windows-based computer
software program that estimates volatile organic material (VOM) and
hazardous air pollutant (HAP) emissions from fixed- and floating-roof
storage tanks. TANKS is based on the emission estimation procedures
from Chapter 7 of USEPA's Compilation Of Air Pollutant Emission
Factors (AP-42). TANKS will run under Windows 95, 98, or Windows NT.
The program requires 8 MB of random access memory (RAM). The
installed program requires 15 MB of available hard disk space. TANKS
is designed for operation from a PC's hard drive.
SPECIATE is USEPA's repository of
Total Organic Compound (TOC) and Particulate Matter (PM) speciated
profiles for a variety of sources for use in source apportionment
studies. SPECIATE will run under under Windows 95/98 or Windows NT.
The single file install version EXE file is a self-extracting 3 MB
file. A 3-floppy disk image version is also available below. The
extracted files will require 10.1 MB of hard disk space.
The Air CHIEF CD-ROM gives the
public and private sector users access to air emission data specific
to estimating the types and quantities of pollutants that may be
emitted from a wide variety of sources. Updated annually, Air CHIEF
offers on one disc literally thousands of pages contained in some of
EPA's most widely used and requested documents. Included are the US
EPA Emission Factor and Inventory Group's most popular emission
estimation tools. Air CHIEF is published annually.
