tional ambient air quality standard for carbon monoxide in that
portion within the period required under this part the State may
petition the Administrator to make a finding that the State would
have been able to make such demonstration but for the failure of
one or more other States in which other portions of the area are
located to commit to the implementation of all measures required
under section 187 (relating to plan submissions for carbon
monoxide nonattainment areas). If the Administrator makes such
finding, in the portion of the nonattainment area within the
State submitting such petition, no sanction shall be imposed
under section 179 or under any other provision of this Act, by
reason of the failure to make such demonstration.
"(f) Reclassified Areas.-Each State containing a carbon monoxide
nonattainment area reclassified under section 186(b)(2) shall meet the
requirements of subsection (b) of this section, as may be applicable
to the area as reclassified, according to the schedules prescribed in
connection with such requirements, except that the Administrator may
adjust any applicable deadlines (other than the attainment date) where
such deadlines are shown to be infeasible.
"(g) Failure of Serious Area to Attain Standard.-If the
Administrator determines under section 186(b)(2) that the national
primary ambient air quality standard for carbon monoxide has not been
attained in a Serious Area by the applicable attainment date, the
State shall submit a plan revision for the area within 9 months after
the date of such determination. The plan revision shall provide that a
program of incentives and requirements as described in section
182(g)(4) shall be applicable in the area, and such program, in
combination with other elements of the revised plan, shall be adequate
to reduce the total tonnage of emissions of carbon monoxide in the
area by at least 5 percent per year in each year after approval of the
plan revision and before attainment of the national primary ambient
air quality standard for carbon monoxide.".
