                subpart 1--nonattainment areas in general
 
Sec. 7505a. Maintenance plans


(a) Plan revision

    Each State which submits a request under section 7407(d) of this 
title for redesignation of a nonattainment area for any air pollutant as 
an area which has attained the national primary ambient air quality 
standard for that air pollutant shall also submit a revision of the 
applicable State implementation plan to provide for the maintenance of 
the national primary ambient air quality standard for such air pollutant 
in the area concerned for at least 10 years after the redesignation. The 
plan shall contain such additional measures, if any, as may be necessary 
to ensure such maintenance.

(b) Subsequent plan revisions

    8 years after redesignation of any area as an attainment area under 
section 7407(d) of this title, the State shall submit to the 
Administrator an additional revision of the applicable State 
implementation plan for maintaining the national primary ambient air 
quality standard for 10 years after the expiration of the 10-year period 
referred to in subsection (a) of this section.

(c) Nonattainment requirements applicable pending plan approval

    Until such plan revision is approved and an area is redesignated as 
attainment for any area designated as a nonattainment area, the 
requirements of this part shall continue in force and effect with 
respect to such area.

(d) Contingency provisions

    Each plan revision submitted under this section shall contain such 
contingency provisions as the Administrator deems necessary to assure 
that the State will promptly correct any violation of the standard which 
occurs after the redesignation of the area as an attainment area. Such 
provisions shall include a requirement that the State will implement all 
measures with respect to the control of the air pollutant concerned 
which were contained in the State implementation plan for the area 
before redesignation of the area as an attainment area. The failure of 
any area redesignated as an attainment area to maintain the national 
ambient air quality standard concerned shall not result in a requirement 
that the State revise its State implementation plan unless the 
Administrator, in the Administrator's discretion, requires the State to 
submit a revised State implementation plan.
