With the passage of Senate Bill (SB) 1025 during the 2010 Special Session, the Building Codes Division (BCD) was directed to adopt a radon mitigation standard by January 1, 2011 for "new" public buildings which are constructed in Baker, Clackamas, Hood River, Multnomah, Polk, Washington and Yamhill Counties for which initial building permits are issued on or after April 1, 2013. The bill required the Building Codes Structures Board (BCSB) to consider radon mitigation standards recommended by the U.S. Environmental Protection Agency (EPA).

With the assistance of key stakeholders, the BCSB recommended adoption of a new Section 1811 for inclusion in the 2010 Oregon Structural Specialty Code in keeping with the January 1, 2011 legislative timeline.

The purpose of the current ad hoc group is to participate in the review and recommendation of further refinements to Section 1811 as the division moves forward with the April 1, 2013 implementation date.
