Title II of the Clean Air Act, (42 U.S.C. 7521 et seq.; CAA), charges the Environmental Protection Agency (EPA) with issuing certificates of conformity for those engines and vehicles that comply with applicable emission requirements. The emission values achieved during certification testing may also be used in the Averaging, Banking, and Trading (ABT) Program. The program allows engine manufacturers to bank credits for engine families that emit below the standard and use the credits to certify engine families that emit above the standard. They may also trade banked credits with other manufacturers. Participation in the ABT program is voluntary.
The CAA also mandates EPA to verify that manufacturers have successfully translated their certified prototypes into mass-produced engines; and that these engines comply with emission standards throughout their useful lives. EPA verifies this through âCompliance Programsâ which include Production Line Testing (PLT), In-use Testing and Selective Enforcement Audits, (SEAs). In-use testing allows manufacturers and EPA to verify compliance with emission standards throughout an engine familyâs useful life. Through SEAs, EPA verifies that test data submitted by engine manufacturers is reliable and testing is performed according to EPA regulations.
Under the Transition Program for Equipment Manufacturers (TPEM), NRCI equipment manufacturers were able to delay compliance with Tier 4 standards for up to seven years as long as they comply with certain limitations. The program, has ended for all power categories. This includes hardship relief. All TPEM forms, except the reporting templates and the bond worksheet are being retired in this action. Participants are required to keep records âfor at least five full years after the final year in which allowances are available for each power categoryâ (40 CFR 1039.625(h).
The information requested is collected by the Compliance Division (CD), Office of Transportation and Air Quality, Office of Air and Radiation, EPA. CD uses this information to issue certificates of conformity and ensure that manufacturers comply with applicable regulations and the CAA. Some HD data is also used by the National Highway Traffic Safety Administration (NHTSA) to implement their programs under 49 USC 32902. EPAâs and NHTSAâs Office of Enforcement and Compliance Assurance and the Department of Justice may use the information for enforcement purposes.
Manufacturers may assert a claim of confidentiality over information provided to EPA. Confidentiality is granted in accordance with the Freedom of Information Act and EPA regulations at 40 CFR Part 2.
US Code:
49 USC 32902
Name of Law: Clean Air Act, Title II
The increase in responses is due to an increase in certification applications in the nonroad compression-ignition (NRCI) engine sector tempered by a sharp reduction in TPEM responses as the program has ended. The reduction in burden is related to the end of TPEM. The cost increase is solely due to the addition of DF verification testing and inflation.
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.
