Clean Air Act section 231 (42 U.S.C. 7571) authorizes EPA to adopt emission standards for aircraft engines. The Clean Air Act additionally provides broad authority for EPA to collect information related to the regulations we adopt for aircraft and other emission sources (42 U.S.C. 7414(a)(1)). EPA is accordingly adopting a new set of emission standards for aircraft gas turbine engines and adding a requirement for manufacturers to submit information related to compliance with the emission standards.
Clean Air Act section 231 (42 U.S.C. 7571) authorizes EPA to adopt emission standards for aircraft engines. The Clean Air Act additionally provides
broad authority for EPA to collect information related to the regulations we adopt for aircraft and other emission sources (42 U.S.C. 7414(a)(1)).
EPA is accordingly adopting a new set of emission standards for aircraft gas turbine engines and adding a requirement for manufacturers to submit
information related to these standards.
EPA will use the data to verify compliance with emission standards and to better understand the characteristics of aircraft engines that are subject to
emission standards, including any ways in which emission standards influence engine designs. This information will be very helpful in future
rulemakings as we continue to explore appropriate and achievable emission standards for aircraft engines. This will be especially useful in
evaluating alternative approaches to specifying the transition to new standards. For example, we may want to specify a certain number of allowable
exemptions for a transition period, or allow manufacturers to "earn" an allowance to produce higher-emitting engines for a time with emission credits,
offsetting the higher emissions with other engines that have emission levels below what would otherwise be required.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
