EPA Recommends States Reference ANSI/AARST Radon Standards

On August 29, 2019, the U.S. Environmental Protection Agency EPA released guidance recommending that states reference the most current voluntary consensus-based standards (VCS) when implementing their radon programs.

Today there are ten radon VCS posted on the EPA Radon Standards of Practice webpage, all developed by the ANSI-Accredited AARST Consortium on National Radon Standards. EPA’s outdated and unsupported Radon Standards have finally been officially archived.

Since 2012, the U.S. Environmental Protection Agency (EPA) has been actively participating in the radon industry-led ANSI/AARST voluntary consensus-based standards (VCS) process. For more information, please visit “EPA Guidance on the Use of Voluntary Consensus Standards for State Indoor Radon Grant Recipients.”

AARST has collaborated with EPA and CRCPD to provide public access to these standards. AARST recently updated their standards webpage, granting public read-only access to all standards, with options to download and print copies available for purchase through ANSI.
