For Fairbanks North Star Borough Residents only:

January 1, 2010 - The Fairbanks North Star Borough (FNSB) I/M Program has been suspended as of this date.

Several years ago, the FNSB requested the Department of Environmental Conservation (DEC) approve their request to end the FNSB I/M Program. DEC, after careful consideration, agreed with the FNSB that suspension of the I/M program would not adversely affect the carbon monoxide maintenance status of the Borough. The State Implementation Plan (SIP) was updated and submitted to EPA for their approval on June 5, 2008. The FNSB Assembly, in the spring of 2009, gave their approval for ending the I/M program on December 31, 2009.

After much deliberation, in December 2009, EPA finalized their approval for discontinuing the Fairbanks Inspection and Maintenance Program as an active control measure in the SIP, allowing the FNSB I/M Program suspension on January 1, 2010. The I/M Program was shifted to a contingency measure in the SIP, meaning if, in the future, carbon monoxide problems return within the FNSB, the I/M Program will be an option for control.

Portions of the April 2008 SIP (PDF) - details the FNSB I/M Program suspension.
