Improving Access to Air Toxics Data
Through its Air Toxics Strategy, EPA’s Office of Air Quality Planning and Standards (OAQPS) is focused on improving its approach to identify and address existing, emerging, and future air toxics issues in the United States. Air toxics are generally a localized issue, and identifying areas of concern is critical in our mission to protect human health and the environment. Data and risk analysis are important components of this strategy, helping us provide communities – especially those with environmental justice concerns – with more complete information about their air quality. EPA is committed to providing updated data to inform the public about their potential risks from air toxics.
Over the next few years, the agency will be transitioning to an improved approach to share air toxics data faster and more regularly with the public. Each annual data release will provide the latest year for which EPA has a complete, quality assured emissions inventory from which to calculate risk. The tentative schedule would allow EPA to release updated information about the estimated risks of air toxics using the latest air emissions inventory (2017) in late 2021 at the same time as the next version of the agency's environmental justice screening tool, EJSCREEN. EPA intends to share the 2018 results in 2022, and 2019 results in 2023. Ultimately, EPA will start reporting air toxics data each year in the annual Air Trends Report. This will enable users to gain more timely air quality information on air toxics, as well as see trends in emissions and risks over time.
A summary of this improved approach is available in the Air Toxics Data Update document.
