(a) Monitoring.--
(1) In general.--Not later than 18 months after the date of
enactment of this Act, the Administrator shall publish notice
in the Federal Register of, take public comment for a period of
not less than 60 days regarding, and take final action to
design and launch a plan and implement a program to administer
or conduct, pursuant to authority provided under the Clean Air
Act (42 U.S.C. 7401 et seq.), including sections 103, 112, 113,
114, and 303 of that Act (42 U.S.C. 7403, 7412, 7413, 7414,

best available form of fenceline monitoring of stationary
sources of hazardous air pollutants that are on the list
developed under subsection (c), including through expansion of
the National Air Toxics Trends Network or through creating a
new network, as appropriate.
(2) Monitoring period.--
(A) In general.--The Administrator shall ensure
monitoring begins pursuant to this section not later
than 18 months after the date of enactment of this Act
and shall maintain the monitoring required under
paragraph (1) for a period of not less than 6 years
after the date on which the monitoring required under
that paragraph begins.
(B) Subsequent monitoring.--After the 6-year period
described in subparagraph (A), the Administrator shall
maintain the emissions measurement and quantification
program under paragraph (1), consistent with this
section, through--
(i) maintaining monitors at all or some
sources under the program under paragraph (1);
and
(ii) adding or moving monitors under the
program under paragraph (1) to additional
sources, following the process for substitution
of sources in subsection (g).
(C) Shortened period.--If the Administrator
determines, after public notice and a public comment
period of not less than 60 days, that 6 years of
monitoring, as required under subparagraph (A), is not
necessary to protect public health or ensure compliance
at the source or the facility involved, the
Administrator may reduce or end the monitoring after at
least 3 years of monitoring has occurred.
(D) Additional inspections and testing.--In
addition to fenceline monitoring under the program
under paragraph (1), the Administrator shall use the
authority of the Administrator to inspect and require
emission testing at sources on the list published
pursuant to subsection (c) to the extent necessary to
identify and address the emissions crossing the
fenceline.
(b) Publication of Results.--
(1) In general.--The Administrator shall publish and
maintain the plans for and the results of all measurements,
including fenceline monitoring, conducted under the program
under subsection (a)(1) on the website of the Environmental
Protection Agency--

not later than 1 month after the date of collection of
the data; and
(B) made publicly available as expeditiously as
practicable, but in any case not later than 7 days
after the electronic submission of the data.
(c) List of Sources.--
(1) Development.--
(A) In general.--Not later than 270 days after the
date of enactment of this Act, the Administrator shall
publish, after public notice and a public comment
period of not less than 60 days, a list of stationary
sources of hazardous air pollutants that, subject to
subparagraph (B) do not already have fenceline
monitoring in operation that is producing publicly
available data and includes--
(i) at least 45 of the sources listed--
(I) as high-priority facilities in
Appendix A of the report of the Office
of Inspector General of the
Environmental Protection Agency
numbered 20-N-0128 and dated March 31,
2020; or
(II) as contributing to high cancer
risk at the census block level in
Appendix C of the report of the Office
of Inspector General of the
Environmental Protection Agency
numbered 21-P-0129 and dated May 6,
2021; and
(ii) at least 55 other major sources or
area sources that meet the criteria described
in paragraph (2).
(B) Substitution.--
(i) In general.--If the Administrator
determines, after public notice and a public
comment period of not less than 60 days, that a
source described in subparagraph (A)(i) no
longer contributes to high health risks or
impacts that warrant continued monitoring to
advance public health protection, inform
improved compliance, or improve available data
quality, the Administrator shall--
(I) cease to include that source in
the list under subparagraph (A); and
(II) include instead an additional
major source or area source described
in subparagraph (A)(ii) to ensure that
the list under subparagraph (A)
includes not fewer than 100 high-
priority sources.
(ii) Description of reasons.--For the
purpose of providing notice, the Administrator
shall publish in the Federal Register, and seek
public comment for a period of not less than 60
days with respect to--
(I) any determination to make a
substitution under clause (i); and
(II) an explanation of the reasons
for any such determination
demonstrating, based on monitoring data
or other reliable information, that the
substitution is likely to ensure that
monitoring under this section occurs at
the sources causing or contributing to
the highest potential health risks or
other impacts from hazardous air
pollution.
(iii) Requirement.--The Administrator may
include an additional major source or area
source under clause (i)(II) only if the
Administrator determines that the source is, or
is likely to be, contributing local health
risks or impacts that are equivalent to, or
greater than, those of the source for which the
new source is being substituted.
(2) Criteria.--The Administrator may include a major source
or area source described in clause (ii) of paragraph (1)(A) on
the list described in that paragraph only if the source--
(A) emits at least 1 of the pollutants described in
paragraph (3);

in-1,000,000; or
(II) a chronic noncancer hazard
index that is greater than or equal to
1; or
(ii) in a source category with--
(I) a cancer risk that is greater
than 100-in-1,000,000 for the
individual most exposed to emissions
from the source category;
(II) a total organ-specific hazard
index for chronic noncancer risk that
is greater than or equal to 1; or
(III) an acute risk hazard quotient
that is greater than or equal to 1; and
(C)(i) is classified in 1 or more of North American
Industry Classification System codes 322, 324, 325,

(ii)(I) is required to prepare and implement a risk
management plan pursuant to section 112(r) of the Clean
Air Act (42 U.S.C. 7412(r)); and
(II) has had an accidental release required to be
reported during the previous 5-year period pursuant to
sections 68.42 and 68.195 of title 40, Code of Federal
Regulations (as in effect on the date of enactment of
this Act); or
(iii) is determined by the Administrator to be a
high-priority source or facility for emissions
measurement because--
(I) the facility is located within 350 feet
of a residence, school, childcare facility
(including a camp), hospital, park, sports or
recreation facility, or other gathering place,
community center, or institution where children
and families regularly spend time; or
(II) based on the best available science,
the emissions of the source or facility are
likely causing or contributing to, or have the
