FAIRBANKS -- The Environmental Protection Agency says Fairbanks could lose highway money and see federal regulations imposed if it doesn't meet a December deadline for a plan that will meet clean air standards.

Agency officials voiced concerns in a letter to Fairbanks North Star Borough Mayor Luke Hopkins.

The Fairbanks Daily News-Miner reports state and the borough officials are completing a State Implementation Plan.

The document will outline steps the borough and the state will use take to decrease borough air pollution by 2014.

The state's deadline for submitting the plan is Dec. 14.

Borough voters go to the polls Oct. 3 to consider a proposition that would bar the borough from imposing any air quality regulations.

Hopkins says passage would jeopardize state efforts to comply with the implementation plan.
