*Abstract:*                     The currently approved ICR addresses certification and compliance requirements for the following industries: Nonroad (NR) compression-ignition (CI) engines and equipment, marine CI engines in Categories 1 and 2; and heavy-duty (HD) engines. In this revision, the following ICRs are being incorporated, either in whole or in part, to eliminate redundancy: Control of Emissions from New Marine Compression-Ignition Engines at or Above 30 Liters per Cylinder (2060-0641); Engine Emission Defect Information Reports and Voluntary Emission Recall Reports (2060-0048); Emissions Certification and Compliance Requirements for Locomotives and Locomotive Engines (2060-0392); and Certification and Compliance Requirements for Medium- and Heavy-Duty Engines and Vehicles (2060-0678). With this consolidation, we are combining all certification and compliance burden associated with the heavy-duty and nonroad compression-ignition engine, equipment and vehicle industries under a single ICR.                

Title II of the Clean Air Act (CAA), charges EPA with issuing certificates of conformity for those engines and vehicles that comply with applicable emission requirements. Such a certificate must be issued before those products may be legally introduced into commerce. To apply for a certificate of conformity, manufacturers are required to submit descriptions of their planned production, descriptions of emission control systems and test data. The emission values achieved during certification testing may also be used in the Averaging, Banking, and Trading (ABT) Program, which 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.

The CAA also mandates EPA verify that manufacturers have translated their certified prototypes into mass produced engines; and that these engines comply with emission standards throughout their useful lives. EPA verifies this through Compliance Programs, including Production Line Testing (PLT), In-use Testing and Selective Enforcement Audits (SEAs). PLT is a self-audit program that allows marine engine manufacturers to monitor their products' emissions profile with statistical certainty and minimize the cost of correcting errors through early detection. In-use testing verifies compliance with emission standards throughout an engine family's 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 may delay compliance with Tier 4 standards for up to seven years if they comply with certain limitations. The Program seeks to ease the impact of new emission standards on equipment manufacturers as they often need to redesign their products.

*Form Numbers:*                     HD/NR Engine Manufacturer Annual Production Report (5900-90); AB&T Report for Nonroad Compression Ignition Engines (5900-125); AB&T Report for Heavy-duty On-highway Engines (5900-134); AB&T Report for Locomotives (5900-274); AB&T Report for Marine Compression-ignition Engines (5900-125); PLT Report for Marine CI CumSum (5900-297); PLT Report for Marine CI Non-CumSum (5900-298); PLT Report for Locomotives (5900-135); PLT Report for Locomotives (5900-273); In-use Testing for Locomotives (5900-93); Replacement Engine Exemption Report (6900-5415); HD Defect Information Reports (590-301); HD Voluntary Emissions Recall Reports VERRs (590-300); HD VER Quarterly Reports (590-302); HD Alternative Fuel Conversions of Intermediate Age (5900-338); HD Alternative Fuel Conversions Outside of Useful Life (5900-259); TPEM Equipment Manufacturer Notification (5900-242); TPEM Equipment Manufacturer Report (5900-240); TPEM Engine Manufacturer Report (5900-241); TPEM Importers Notification (TBD); TPEM Importers Annual Report (TBD); TPEM Statement to Comply (5900-239); TPEM Hardship Relief Application Questionnaire (5900-465); TPEM Hardship Relief Prescreening Questionnaire (5900-465)                          ( print page 42291)    

*Respondents/affected entities:*                     Manufacturers of engines, equipment and vehicles in the nonroad compression ignition (CI), marine CI, locomotives and medium- and heavy-duty on-highway industries; Marine CI vessel owners and operators and owners of HD truck fleets.                

*Respondent's obligation to respond:*                     Regulated manufacturers must respond to this collection if they wish to sell their products in the US, as prescribed by Section 206(a) of the CAA (42 U.S.C. 7521). Participation in some programs such as ABT and TPEM is voluntary, but once a manufacturer has elected to participate, it must submit the required information.                

*Estimated number of respondents:*                     468 (total).                

*Frequency of response:*                     Quarterly, Annually, On Occasion.                

*Total estimated burden:*                     127,900 hours per year. Burden is defined at 5 CFR 1320.03(b).                

*Total estimated cost:*                     $21,639,590 (per year), which includes an estimated $11,682,548 annualized capital or maintenance and operational costs.                

*Changes in the Estimates:*                     There is a net decrease of 73,137 hours in the total estimated burden. This decrease is due to: (1) A decrease in TPEM respondents; (2) respondents' reliance on carry-over testing data; and 3) eliminating duplication.
