The North Star Fairbanks Borough Assembly has passed an ordinance setting emission standards for wood and other fuel burners.

Under the ordinance, the Fairbanks Daily News-Miner reports, fuel-burning devices are limited to 30 percent opacity. The ordinance goes into effect Oct. 29.

The move by the borough followed nearly two hours of heated public testimony Thursday night. The new standard is part of a wider range of efforts by the borough to tackle the problem of air pollution, which exceeds federal standards.

Sponsors say the new measure won't affect anyone who is using their heating devices responsibly.
