This information collection is being
conducted by the Environmental Protection Agency's (EPAs) Office of
Air and Radiation (OAR) pursuant to section 114 of the Clean Air
Act, as amended (CAA or the Act) to assist the Administrator of EPA
in developing emissions standards and/or to inform future policy
making decisions for aircraft gas turbine engines pursuant to
section 231 of the Act. Under CAA section 231, the EPA is
responsible for establishing standards for emissions from aircraft
engines, and under CAA section 232, the Federal Aviation
Administration (FAA) is responsible for enforcing these standards.
The EPA and the FAA traditionally work within the standard-setting
process of the International Civil Aviation Organization (ICAO) to
establish international emission standards and related
requirements, which individual nations later adopt into domestic
law in fulfillment of their obligations under the Convention on
International Civil Aviation (Chicago Convention). Historically,
international emission standards have first been adopted by ICAO,
and subsequently the EPA has initiated rulemakings under CAA
section 231 to establish domestic standards that are at least as
stringent as ICAOs standards.
There is decrease of 217 hours
in the total estimated respondent burden compared with the ICR
currently approved by OMB. This decrease is due to one-time
start-up costs to conduct nvPM measurements from jet engines that
were included in the previous ICR renewal. The initial cost for
manufacturers was capital and labor intensive. These one-time costs
were incurred in the past 3 years and are not expected to need to
be repeated for these engines now that the data has been collected.
If manufacturers develop a new subsonic engine with a thrust
greater than 26.7kN, the nvPM measurements will need to be verified
by the FAA. The introduction of new aircraft engines does not
happen on a very frequent basis. The EPA is estimating that each
manufacturer may introduce one subsonic engine over 26.7kN over the
next three years, for a total of 6 engines (compared to an
estimated 33 engines in the previous ICR).
