The Antelope Valley Air Quality Management District Board was meeting on Tuesday to discuss and vote on approving the transfer of critical emissions credits for a proposed Palmdale power plant.

More than 400 people turned out for the meeting taking place at Antelope Valley College, according to media reports. A decision had not been made by mid-afternoon.

The credits would allow the plant to discharge 152 tons of nitrogen oxide a year and 60 tons of volatile organic compounds a year. They will be acquired from the Mojave Desert Air Quality Management District and the San Joaquin Valley Air Pollution Control District and transferred to the Antelope Valley Air Quality Management District.

The transfer is the last major hurdle for the project, which Palmdale is selling off to Summit Power Group, in Seattle, for about $27 million. The deal is expected to close early next year provided the credits come through. Summit would pay for the acquired credits.

The natural gas-fired power plant already has been approved by the California Energy Commission and the U.S. Environmental Protection Agency.

The seven-member board is made up of two representatives from Palmdale, two from Lancaster, two from Los Angeles County, and one at-large member. The chairman is Marvin Crist, the vice mayor of Lancaster.
