In the 1987 notice, EPA proposed that the ORVR standards apply to light-duty trucks (LDTs) and heavy-duty vehicles (HDVs) as well as light-duty vehicles (LDVs). EPA reiterated this proposal in the 1991 and 1993 notices. Between 1987 and the present, the 1990 CAA amendments addressed ORVR controls, explicitly mandating onboard controls only for LDVs in section 202(a)(6). Thus, to apply the ORVR requirement beyond LDVs, EPA proposed to rely on the general authority under section 202(a)(1) of the Act. This permits the Administrator to put forth regulations for emissions which "cause or contribute to air pollution which may be reasonably anticipated to endanger public health or welfare". The commenters agreed that EPA has the authority to promulgate an ORVR requirement for LDTs/HDVs under CAA section 202(a)(1) general authority.
