paragraph (3) the following: 
‘‘(4) OPTION FOR EXPANDED MONITORING.— 
‘‘(A) IN GENERAL.—Any State may include in 
a State implementation plan a program for moni-
toring one or more covered criteria air pollutants in 
one or more designated areas by— 
‘‘(i) continuing to use the monitoring sys-
tem (including for purposes of baseline meas-
urements) that was in operation as of the sub-
mission of the revision to the plan; and 
‘‘(ii) greatly increasing the number of air 
quality sensors, which may include mobile sen-
sors, for such monitoring system. 
‘‘(B) STATE DISCRETION.—Subject to subpara-
graphs (C) and (D), the Administrator shall allow a 
State to make a revision to a State implementation 
plan in accordance with subparagraph (A) at the 
State’s discretion.

such monitoring meets all applicable data quality 
standards under this Act. 
‘‘(D) REVIEW BY ADMINISTRATOR.—A State’s 
annual demonstration under subparagraph (C) is 
deemed to have met the standard described in such 
subparagraph unless the Administrator issues a 
written response— 
‘‘(i) finding that such standard is not met; 
and 
‘‘(ii) explaining the basis for such finding. 
‘‘(E) GREATER

FLEXIBILITY.— 
With respect to each designated area in which a 
State conducts monitoring pursuant to this para-
graph, the Administrator— 
‘‘(i) shall not require any particular meth-
od of monitoring to be used or not used, so long 
as the data derived from such monitoring meets 
all applicable data quality standards under this 
Act, as described in subparagraph (C); and 
‘‘(ii) shall allow the State involved to con-
sider data derived from monitoring pursuant to 
this paragraph in making any determination on 
whether an exceedance of the national ambient 
air quality standard for the criteria air pollut-
ant involved has occurred.
