The California Supreme Court's refusal affirms a Bay Area Air Quality Management District limit on burning wood, fire logs or wood pellets on nights when air quality is expected to exceed public health standards.

The appeal was brought by Duraflame Inc., which argued that its logs burn cleaner than other fuel types and should be exempt from the ban.

Duraflame appealed to California's high court after losses in both Alameda County Superior Court and a state appeals court.
