The Port of Stockton has a new tenant. Pacific Ethanol Inc., headquartered in Sacramento, has leased 30 acres at the port. The company has already lined up construction contractors a $92 million plant. The plant could produce up to 60 million gallons of ethanol per year and with about 35 employees.  Pacific Ethanol has good timing.  California legislation passed last year requires that carbon dioxide emissions be cut. Also, Gov. Schwarzenegger signed an executive order this month to increase the consumption of biofuels made in California. This will provide a boost as well. Pacific Ethanol might soon find itself in a hungry California market.
