Sonoma County apparently is the biggest wood-burning air polluter in the Bay Area during no-burn days, and this year the regional air quality police are cracking down more than ever.
Last year, the Bay Area Air Quality Management District received 409 wood-burning complaints from Sonoma County neighborhoods. Inspection patrols, many stemming from such complaints, resulted in the issuing of 110 wood-burning citations, the most of any county in the nine-county district, officials said.
Across the Bay Area district, there were 3,777 complaints and 346 violations, with most violators receiving a warning letter. But this winter, the district is no longer issuing warnings. Instead, first-time violators will be given the option of paying a $100 fine or taking a smoke awareness course online or by mail.
The district, which covers most of Sonoma County, except for north of Windsor and west of Sebastopol, issued a Spare the Air alert for today, the fourth consecutive wood-burning ban and the seventh since the Spare the Air season started Nov. 1.
The season, which lasts until Feb. 28, is an effort to reduce air pollution during winter months, when the skies over southern Sonoma County can become unhealthy. Of the nine counties in the Bay Area air district, the skies over Sonoma County are among the most heavily polluted during winter.
But the district's heavy hand has some fireplace and wood-burning stove vendors crying foul because their modern, EPA-certified products are extremely efficient and clean.
"I understand the restrictions on wood burning, but the industry is very clean now," said Pete Orrfelt, store manager of Malm Fireplace Center in Santa Rosa. "A modern wood stove emits an average of up to about 3.5 grams of particulate matter per hour. The maximum allowable by the EPA is 8.5 grams per hour."
Orrfelt said the district and the media have "villainized" wood burning and made no distinction between old and new technologies.
While newer stoves and fireplaces do burn more efficiently, many of the Bay Area's 1.4 million fireplaces and wood stoves are older, less-efficient models, said Aaron Richardson, a spokesman for the air quality agency.
"Based on our emissions analysis, wood burning is responsible for 30 percent of the fine-particle pollution in the wintertime in the Bay Area," Richardson said.
