PAGE: B3Air quality regulators on Wednesday cited a Petaluma quarry that is experimenting with a new process to make pavement out of old tires.

Dutra Materials suspended its rubberized asphalt operations and scheduled a meeting today with air quality officials to discuss the issue, said Brian Peer, Dutra general materials manager. San Rafael-based Dutra owns four quarries, including one in Petaluma . It is the main supplier of rubberized asphalt in the North Bay , according to Caltrans spokesman Colin Jones.

Jones said Caltrans is required to use recycled tires in road materials.

Dutra is currently supplying North Bay Construction Co., which has a $2 million contract to repave 8 1/2 miles of Highway 1 from the county line north, Jones said.

An air quality inspector issued a violation notice Wednesday following complaints about white smoke and a burning-tire odor, said Lucia Libretti, a spokeswoman for the Bay Area Air Quality Management District.

Libretti said the smoke is not believed to be hazardous but is considered a nuisance.

She said the company will be fined, but the amount won't be determined until after a background check to see if there have been any other violations.

Amy Dutra said the company has had one or two air quality violations this year, but they were not related to rubberized asphalt.
Dutra is experimenting with a new process that mixes ground-up rubber with hot aggregate, Peer said.
