Are there any exemptions to the wood-burning devices curtailment during Winter Spare the Air Alerts?

Yes. If electrical power OR natural gas service is not available in your area, you may qualify for an exemption. You may also qualify for an exemption if operating a wood-burning device is your only source of heat. Please see the BAAQMD regulation for a complete description of exemptions: https://www.baaqmd.gov/rules-and-compliance/wood-smoke.
