2020 Community-Scale Air Toxics Ambient Monitoring Grants Competition Selections

September 28, 2020 – EPA has selected 11 state and local agencies to receive grants under the 2020 Community-Scale Air Toxics Ambient Monitoring grants competition. These grants will support monitoring in communities and provide important information on air toxics, including ethylene oxide, chloroprene, benzene, 1,3-butadiene, and toxic metals. Funding for the grants comes from State and Tribal Assistance (STAG) funding. Congress appropriates STAG funds for state, local and tribal air agencies to use in implementing and maintaining environmental programs.  To support Administrator’s goal of a clean and healthy environment, EPA anticipates awarding these grants once all legal and administrative requirements are satisfied.

The 11 state and local agencies selected to receive grants will conduct projects in these categories:

  • Characterizing the impacts of air toxics in a community (community-scale monitoring);
  • Assessing the impacts of air toxics emissions from specific sources (near-source monitoring);
  • Evaluating new and emerging testing methods for air toxics.
  • The grants funding for the 2020 competition totals $5 million dollars. EPA anticipates that it will award the grants once all legal and administrative requirements are satisfied. The Agency anticipates providing selected agencies funding for their work in the fiscal yeas 2021 and 2022. The selected grant recipients and anticipated award amounts are listed below.
