Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER II — EMISSION STANDARDS FOR MOVING SOURCES › Part C — Clean Fuel Vehicles › § 7587
Fleets can meet clean‑vehicle requirements by converting existing or new gasoline or diesel vehicles into clean‑fuel vehicles, and a converted vehicle counts the same as buying a clean‑fuel vehicle. Fleets are not forced to convert or to buy converted vehicles. The EPA Administrator must write rules about conversions within 24 months after November 15, 1990. The rules must make sure converted vehicles meet the same clean‑fuel standards and generally follow the same enforcement and administration rules, though the Administrator may adjust rules for conversions. Anyone who converts vehicles is treated as a manufacturer for enforcement under sections 7525 and 7541, but only must give warranties required by this part. Conversions that follow the EPA rules are not treated as illegal tampering under section 7522(a)(3). The Secretary of Transportation must make any needed vehicle safety rules for conversions.
