Proposed Rule -- Control of Air Pollution from Aircraft and
Aircraft Engines; Emission Standards and Test Procedures (Published
September 30, 2003)
The U.S. Environmental Protection Agency (EPA) is proposing to
amend the existing emission standards for oxides of nitrogen (NOx)
for new commercial aircraft engines. These new standards are equivalent
to the latest NOx emission standards of the United Nations International
Civil Aviation Organization (ICAO), and thereby would bring the
United States aircraft standards into alignment with the international
standards. These standards would go into effect in 2004 and would
apply to new aircraft engines utilized on commercial aircraft
that include small regional jets, single-aisle aircraft, twin-aisle
aircraft, and 747s and larger aircraft.
A public hearing on the rule will be held on November 13, 2003 and
comments will be accepted until December 15, 2003.

- For aviation emission inventory analysis, a useful tool is the
Federal
Aviation Administration's (FAA) Emissions and Dispersion Modeling
System (EDMS).
In cases where EDMS does not include necessary emission factors,
such as aircraft particulate matter (PM), use the best available
information. Available information on particulate matter emission
factors includes EPA documentation, available through contacting
the ASD information phone number and e-mail address shown above.
- Aircraft
Engine Emissions Data Bank
A comprehensive database of aircraft engine emissions certification
data has been developed during the course of work carried out
by the International Civil Aviation Organization (ICAO). This
data and related information are available at the ICAO Aircraft
Engine Exhaust Emissions Data Bank.
- November 1991: "Nonroad Engine and Vehicle Emission Study
Report" (EPA-21A-2001 or EPA460/3-91-002).
This "nonroad study" quantifies the contribution of nonroad
sources to air pollution, including volatile organic compounds
(VOCs), oxides of nitrogen (NOx), carbon monoxide (CO), and
particulate matter (PM). The study covers 10 equipment
categories, including: lawn and garden equipment, farm and construction
equipment, recreational vehicles, marine vessels, and airport
service equipment.
