Active RRNC Model Code Proposal

Announcement – December 11, 2009

This is an announcement for a new effort to develop an ANSI/AARST model code for Active Radon Resistant New Construction (Active RRNC) in high radon areas. This new model code is intended to support code change proposals under consideration in the International Residential Code (IRC). Modifying the building code to require an Active Soil Depressurization (ASD) system in all new homes in high radon areas in the United States will further the joint goals of the Environmental Protection Agency (EPA), Conference of Radiation Control Program Directors (CRCPD) and the American Association of Radon Scientists and Technologists (AARST) to double the radon mitigation rate in the United States over the next five years.
