(1) In general.--Not later than 18 months after the date on
which an air quality system deployed pursuant to subsection (a)
has been monitoring air quality data for 1 year, the
Administrator shall determine whether the air quality systems
deployed in the applicable census tract or county reported air
pollution levels over the 1-year period ending on the date of
the determination that reached or exceeded 98 percent of the
level of any applicable national ambient air quality standard
established under section 109 of the Clean Air Act (42 U.S.C.
7409) for any air pollutant.
(2) Requirement.--If the Administrator makes a
determination under paragraph (1) that an air pollutant
described in subsection (b)(1) met or exceeded the threshold
described in that paragraph, the Administrator shall, not later
180 days after the date of the determination, ensure that
Federal reference method monitors or Federal equivalent method
monitors are installed and in operation within that census
tract or county for each pollutant that met or exceeded the
threshold.
(3) Exceptions.--The Administrator shall waive the
requirement of paragraph (2) if the Administrator finds, within
the 180-day period described in that paragraph, and after
providing notice and an opportunity for public comment, that
based on clear and convincing evidence--

the determination described in paragraph (2) were so
inaccurate as to provide no reasonable basis for
finding that levels of the relevant pollutant reached
98 percent of the level of the national ambient air
quality standard established under section 109 of the
Clean Air Act (42 U.S.C. 7409) for the relevant
pollutant; or
(B) complementary data, such as information on the
ambient matric, meteorology, measurements from other
