Text: determination under paragraph (2) the Adminis- trator shall, within 12 months after completion of the study under paragraph (1), promulgate (and from time to time revise) regulations con- taining standards applicable to emissions from those classes or categories of new nonroad en- gines and new nonroad vehicles (other than locomotives or engines used in locomotives) which in the Administrator’s judgment cause, or contribute to, such air pollution. Such standards shall achieve the greatest degree of emission reduction achievable through the application of technology which the Administrator determines will be available for the engines or vehicles to which such standards apply, giving appropriate consideration to the cost of applying such tech- nology within the period of time available to manufacturers and to noise, energy, and safety factors associated with the application of such technology. In determining what degree of re- duction will be available, the Administrator shall first consider standards equivalent in stringency to standards for comparable motor vehicles or engines (if any) regulated under section 7521 of this title, taking into account the technological feasibility, costs, safety, noise, and energy factors associated with achieving, as appropriate, standards of such stringency and lead time. The regulations shall apply to the useful life of the engines or vehicles (as determined by the Ad- ministrator).
