Certification and Compliance Requirements for Nonroad Spark-ignition Engines (Renewal)

This information collection is requested under the authority of Title II of the Clean Air Act (42 U.S.C. 7521 et seq.) Under this Title, EPA is charged with issuing certificates of conformity for those engines which comply with applicable emission standards. Such a certificate must be issued before engines may be legally introduced into commerce. To apply for a certificate of conformity, manufacturers are required to submit descriptions of their planned production line, including detailed descriptions of the emission control system, and test data. This information is organized by engine family groups expected to have similar emission characteristics. The emission values achieved during certification testing may also be used in the Averaging, Banking, and Trading (ABT) Program. The program allows manufacturers to bank credits for engine families that emit below the standard and use the credits for families that emit above the standard. They may also trade banked credits with other manufacturers. Participation in the ABT program is voluntary. Different categories of spark-ignition engines may also be required to comply with production-line testing (PLT) and in-use testing. There are also recordkeeping and labeling requirements. This information is collected electronically by the Gasoline Engine Compliance Center (GECC), Compliance Division, Office of Transportation and Air Quality (OTAQ), Office of Air and Radiation of the U.S. Environmental Protection Agency. GECC uses this information to ensure that manufacturers comply with applicable regulations and the Clean Air Act (CAA). It may also be used by the Office of Enforcement and Compliance Assurance (OECA) and the Department of Justice for enforcement purposes. Non- CBI may be disclosed on OTAQ's Web site or upon request under the Freedom of Information Act (FOIA) to trade associations, environmental groups, and the public. Any information submitted for which a claim of confidentiality is made is safeguarded according to EPA regulations at 40 CFR 2.201 et seq.
