40 CFR 89.603 - General requirements for importation of nonconforming nonroad engines.
(a) A nonconforming nonroad engine offered for importation into the United States is to be imported only by an Independent Commercial Importer (ICI) who is a holder of a currently valid certificate of conformity unless an exemption or exclusion is granted by the Administrator under § 89.611 of this subpart. For a nonroad engine imported pursuant to § 89.605, the ICI must hold a currently valid certificate of conformity for that specific nonroad engine model.
(b) Any nonroad engine imported into the United States must have a legible unique engine identification number permanently affixed to or engraved on the engine.
(c) Final admission may not be granted unless:
(1) The nonroad engine is covered by a certificate of conformity issued under subpart B of this part in the name of the ICI and the ICI has complied with all requirements of § 89.605; or
(2) The nonroad engine is modified and emission tested in accordance with the provisions of § 89.609 and the ICI has complied with all other requirements of § 89.609; or
(3) The nonroad engine is exempted or excluded under § 89.611.
(d) The ICI must submit to the Engine Programs and Compliance Division of EPA a copy of all approved applications for certification used to obtain certificates of conformity for the purpose of importing nonconforming nonroad engines pursuant to § 89.605 or § 89.609. In addition, the ICI must submit to the Engine Programs and Compliance Division a copy of all approved production changes implemented pursuant to § 89.605 or subpart B of this part. Documentation submitted pursuant to this paragraph (d) must be provided to the Engine Programs and Compliance Division within 10 working days of approval of the certification application (or production change) by EPA.
(1) The applicable emission standards for engines imported by an ICI under this subpart are the emission standards applicable to the Original Production (OP) year of the engine.
(2) Where engine manufacturers have choices in emission standards for one or more pollutants in a given model year, the standard that applies to the ICI is the least stringent standard for that pollutant applicable to the OP year for the appropriate power category.
(3) ICIs may not generate, use or trade emission credits or otherwise participate in any way in the averaging, banking and trading program.
(4) An ICI may import no more than a total of five engines under this part for any given model year, except as allowed by paragraph (e)(5) of this section. For ICIs owned by a parent company, the importation limit includes importation by the parent company and all its subsidiaries.
(5) An ICI may exceed the limit outlined in paragraph (e)(4) of this section, provided that any engines in excess of the limit meet the emission standards and other requirements outlined in the applicable provisions of Part 89 or 1039 of this chapter for the model year in which the engine is modified (instead of the emission standards and other requirements applicable for the OP year of the vehicle/engine).
