?We still don?t know if a couple of people will participate, but we?ll have three really solid panels,? said Assemblymember Jared Huffman, who is hosting the meeting.

The meeting, which will be held from 9 to 11:30 a.m., will feature three panels ? a panel of proponents, followed by a panel of experts from regulatory agencies and a panel of people with other points of view regarding the plant, proposed for an area just south of Petaluma, near the Petaluma River.

The panel participants will include representatives from the California Department of Fish & Game, Environmental Protection Agency, Bay Area Air Control Quality District, Sonoma County Water Agency, U.S. Army Corps of Engineers and Bay Conservation and Development Commission.

Huffman says he organized the meeting to help raise the awareness of everyone on issues pertaining to the controversial plant. Many local residents have raised concerns about environmental problems that they feel would be caused by the plant.

Congresswoman Lynn Woolsey and state Sen. Mark Leno have agreed to attend. Other invitees include members of the Sonoma County Board of Supervisors and the Petaluma City Council.

The proposed plant would be located between the Petaluma Boulevard South off-ramp of northbound Highway 101 and the railroad tracks. Barges would offload material at a parcel of land between the railroad tracks and the Petaluma River northeast of the rest of the project, and transport material to the site on a conveyor belt over the tracks. It would produce 664,000 tons of material a year, including 225,000 tons of asphalt.

The meeting will be videotaped so that it can be seen by people unable to attend.
