(e) Additional ambient monitors (1) In general The Administrator shall deploy not fewer than 100 Federal reference method monitors or Federal equivalent method monitors for 1 or more air pollutants for which national ambient air quality standards have been established pursuant to section 109 of the Clean Air Act ( 42 U.S.C. 7409 ) in areas— (A) that are unmonitored or undermonitored, as determined by the Administrator; and (B) within which the Administrator determines, after public notice and comment, that adding those monitors is warranted— (i) to detect whether the area is in nonattainment of the applicable national ambient air quality standards; and (ii) to improve the publicly available data on air quality for 1 or more of those air pollutants (or precursors to those air pollutants). (2) Siting determinations In approving sites for new Federal reference method monitors or Federal equivalent method monitors required under this subsection, the Administrator shall prioritize siting of the stations in census tracts or counties in accordance with subsection (d)(2)(B). (3) Relation to previously deployed or planned monitors The Federal reference method monitors required under this subsection shall be in addition to, and not in lieu of, any monitors already deployed or planned for deployment by the Administrator, any State, any other governmental entity, or any other entity prior to the date of enactment of this Act. (f) Report Not later than 2 years after the date of enactment of this Act, the Administrator shall— (1) in coordination with the States, complete an assessment, which includes public input, on the status of all ambient air quality monitors that are part of Federal, State, or local networks and used for determining compliance with national ambient air quality standards; and (2) submit to the Congress and make available on the public website of the Environmental Protection Agency a report that includes— (A) a list of all monitors identified under paragraph (1); and (B) a schedule and plan to restore or replace all monitors included in the list under subparagraph (A) to full operation not later than 16 months of the date of enactment of this Act, except that the schedule and plan shall not apply to monitors— (i) that have been discontinued in accordance with section 58.14(c) of title 40, Code of Federal Regulations (as in effect on the date of enactment of this Act); and (ii) (I) for which such discontinuation is not subject to a judicial challenge; or (II) for which a judicial challenge described in subclause (I) has been fully resolved by a settlement or order that authorizes discontinuation of such monitor. (g) Designations Not later than 2 years after the date on which data is received from a monitor sited pursuant to this section that demonstrates that an area that is designated pursuant to section 107(d)(1) of the Clean Air Act ( 42 U.S.C. 7407(d)(1) ) by the Administrator as in attainment or unclassifiable for an air pollutant is in violation of the applicable national ambient air quality standard, the Administrator shall redesignate pursuant to section 107(d)(3) of such Act ( 42 U.S.C. 7407(d)(3) ) that area as in nonattainment for that pollutant unless the designation is otherwise precluded under this Act. (h) Satellite monitoring (1) Satellite monitoring data (A) Provision of satellite data The Administrator of the Environmental Protection Agency may consult with the Administrator of the National Aeronautics and Space Administration regarding data from the satellites of the National Aeronautics and Space Administration for use in calculating design values under any national ambient air quality standards for PM 10 and PM 2.5 . (B) Regulations required The Administrator of the Environmental Protection Agency may promulgate regulations to specify procedures (including any modeling techniques) for using data described in subparagraph (A) in combination with information from multiple sources, including monitors and modeling, to calculate the expected number of exceedances per year and the design values for PM 10 and PM 2.5 for purposes of determining compliance or noncompliance with the national ambient air quality standards for those pollutants. (2) National Academy of Sciences report (A) In general The Administrator may enter into an arrangement with the National Academy of Sciences under which the National Academy of Sciences agrees to submit a report that describes the actions necessary, including new science and satellite assets to enable the contribution of satellite monitoring to the calculation of design values and nonattainment determinations under any national ambient air quality standards for ozone, oxides of nitrogen, and oxides of sulfur established pursuant to section 109 of the Clean Air Act ( 42 U.S.C. 7409 ). (B) Regulations required (i) In general Not later than December 31, 2023, the Administrator, in coordination with the Administrator of the National Aeronautics and Space Administration and the Administrator of the National Oceanic and Atmospheric Administration, shall promulgate regulations that provide a plan for the use of satellite monitoring data in calculating design values for the pollutants described in subparagraph (A). (ii) Requirement Not later than January 1, 2027, the Administrator shall implement the plan required by clause (i) and provide for use of satellite data in calculating design values for the pollutants described in subparagraph (A). (3) Definition For purposes of this subsection, the term design value means, for each pollutant, the air quality statistic the Administrator defines in part 50 (including appendices) of title 40, Code of Federal Regulations, for comparison with the relevant national ambient air quality standard established under section 109 of the Clean Air Act ( 42 U.S.C. 7409 ), regardless of whether the regulation (including appendices) in part 50 of title 40, Code of Federal Regulations, uses the term design value . (i) Monitoring plans Notwithstanding any other provision of law, the Administrator may not approve a State monitoring plan under section 58.10 of title 40, Code of Federal Regulations (or successor regulations) unless— (1) the State provided, with respect to the State monitoring plan— (A) public notice; (B) not less than 45 days for public comment; and (C) an opportunity for public hearing; and (2) the Administrator— (A) proposes in the Federal Register to approve or disapprove of the State monitoring plan; (B) provides not less than 45 days for public comment on the proposal described in subparagraph (A); and (C) publishes in the Federal Register the final action on the proposal described in subparagraph (A).

Sensor Monitoring (a) Deployment of air quality sensors (1) In general Not later than 2 years after the date of enactment of this Act, the Administrator— (A) shall deploy, in accordance with the prioritization criteria described in section 5(d)(2), not fewer than 1,000 air quality sensors, each of which shall cost not more than $5,000; (B) shall deploy such air quality sensors in clusters of not fewer than five in each of the census tracts or counties selected; (C) before determining and approving sites for such air quality sensors, shall invite, through public notice and other means designed to reach communities disproportionately impacted by air pollution, proposals from or on each behalf of residents of any community for the sites; and (D) may contract with State and local air pollution control agencies to conduct sensor monitoring and report the results. (2) Requirement In carrying out paragraph (1), the Administrator shall select sensors for deployment that— (A) are available on the market at the time of purchase; (B) the Administrator determines will provide data of sufficient accuracy to provide a reasonable basis for determining whether the location in which the sensor is sited is or may be at risk of exceeding the applicable national ambient air quality standard established pursuant to section 109 of the Clean Air Act ( 42 U.S.C. 7409 ); and (C) are the lowest cost available that meet the criteria of subparagraph (B). (3) Exception to cost limitation Notwithstanding paragraph (1), if the Administrator determines in writing that a sensor model to measure a particular pollutant is not available on the market at a price at or below $5,000 each, the Administrator may spend an amount above $5,000 to acquire such sensor model so long as the Administrator complies with subparagraphs (B) and (C) of paragraph (2). (b) Pollutants (1) In general Each air quality sensor deployed pursuant to subsection (a) shall measure ozone, PM 2.5 , oxides of nitrogen, or sulfur dioxide. (2) Determination The Administrator shall determine which pollutant or air pollutants an air quality sensor deployed pursuant to subsection (a) shall monitor based on the pollution sources affecting the area in which the sensor is to be deployed. (c) Determination and installation (1) In general Not later than 18 months after the date on which an air quality sensor deployed pursuant to subsection (a) has been monitoring air quality data for 1 year, the Administrator shall determine whether data from the air quality sensors deployed in the applicable census tract or county shows air pollution levels over the 1-year period ending on the date of the determination that reached 98 percent of the level of the national ambient air quality standard 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 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 the threshold. (3) Exceptions The Administrator shall waive the requirement of paragraph (2) if the Administrator finds, within the 180-day period described in such paragraph, and after providing notice and an opportunity for public comment, that based on clear and convincing evidence— (A) the measurements from the sensor or sensors supporting 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 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 nearby sensors or ambient monitors, modeling, satellite data, or other relevant and reliable information demonstrate that levels of the relevant pollutant could not have plausibly reached 98 percent of the level of such standard. (d) Report Not later than 1 year after the date of enactment of this Act, and not less frequently than every 6 years thereafter, the Administrator shall report on additional areas of decision making where data from low-cost air quality sensors may be relevant and useful. (e) Authorization of appropriations There is authorized to be appropriated to carry out this section $6,000,000. 7. Data requirement To the extent practicable, the Administrator shall integrate the data collected through the programs established under this Act into the Environmental Justice Screening and Mapping Tool (EJSCREEN) of the Environmental Protection Agency or a relevant similar mapping and screening tool.
