G, title IV, § 428(b), Jan. 23, 2004, 118 Stat. 418, provided that: ‘‘Not later than December 1, 2004, the Administrator of the Environmental Protec- tion Agency shall propose regulations under the Clean Air Act [42 U.S.C. 7401 et seq.] that shall contain stand- ards to reduce emissions from new nonroad spark-igni- tion engines smaller than 50 horsepower. Not later than December 31, 2005, the Administrator shall publish in the Federal Register final regulations containing such standards.’’ § 7548. Study of particulate emissions from motor vehicles (a) Study and analysis (1) The Administrator shall conduct a study concerning the effects on health and welfare of particulate emissions from motor vehicles or motor vehicle engines to which section 7521 of this title applies. Such study shall characterize and quantify such emissions and analyze the re- lationship of such emissions to various fuels and fuel additives. (2) The study shall also include an analysis of particulate emissions from mobile sources which are not related to engine emissions (including, but not limited to tire debris, and asbestos from brake lining). (b) Report to Congress The Administrator shall report to the Con- gress the findings and results of the study con- ducted under subsection (a) not later than two years after August 7, 1977. Such report shall also include recommendations for standards or meth- ods to regulate particulate emissions described in paragraph (2) of subsection (a).

High altitude performance adjustments (a) Instruction of the manufacturer (1) Any action taken with respect to any ele- ment of design installed on or in a motor vehicle or motor vehicle engine in compliance with reg- ulations under this subchapter (including any alteration or adjustment of such element), shall be treated as not in violation of section 7522(a) of this title if such action is performed in ac- cordance with high altitude adjustment instruc- tions provided by the manufacturer under sub- section (b) and approved by the Administrator. (2) If the Administrator finds that adjustments or modifications made pursuant to instructions of the manufacturer under paragraph (1) will not insure emission control performance with re- spect to each standard under section 7521 of this title at least equivalent to that which would re- sult if no such adjustments or modifications were made, he shall disapprove such instruc- tions. Such finding shall be based upon min- imum engineering evaluations consistent with good engineering practice. (b) Regulations (1) Instructions respecting each class or cat- egory of vehicles or engines to which this sub- chapter applies providing for such vehicle and engine adjustments and modifications as may be necessary to insure emission control perform- ance at different altitudes shall be submitted by the manufacturer to the Administrator pursuant to regulations promulgated by the Adminis- trator. (2) Any knowing violation by a manufacturer of requirements of the Administrator under paragraph (1) shall be treated as a violation by such manufacturer of section 7522(a)(3) of this title for purposes of the penalties contained in section 7524 of this title.
