Technology Assessment for Air Quality Management Act of 2023

HR 4211 requires the EPA to create and update an online compendium of air quality monitoring technologies, including low-cost sensors and satellite data, to help communities understand local pollution patterns. It establishes a working group with environmental justice community representatives to develop templates for integrated monitoring systems that combine ground sensors, modeling, and satellite data. The bill directs the EPA to conduct a national inventory of existing air monitoring infrastructure and identify high-priority areas - particularly near communities disproportionately affected by pollution - to target future monitoring efforts. This aims to address significant air quality variations (up to 800% block-to-block) and support hyperlocal data use for environmental justice communities.
