Air Quality Guidance for Siting Biorefineries in California
This page last reviewed on November 28, 2011
The Low Carbon Fuel Standard (LCFS) Resolution 09-31 directed the Air Resources Board (ARB or Board) Executive Office to work with local air districts, regulated parties, environmental and public health groups, and other stakeholders to develop a best practices guidance document for use by stakeholders when they are assessing and mitigating the air emissions associated with biofuel production facilities in California. The Guidance identifies the lowest permitted emission limits for stationary source process equipment used at biorefineries and identifies strategies for mitigating mobile source emissions associated with biorefineries.
The Guidance is a resource document developed to assist air quality agencies, local land use planners, environmental and public health groups, project developers, and other stakeholders that would conduct air quality evaluations for new or expanding biorefineries. The Guidance is not intended to substitute for project-specific evaluations conducted at the local level by California air districts, California Environmental Quality Act lead agencies, and other regulatory entities.
Guidance Update Process
In order to keep information on the most stringent emissions limits current, ARB staff will utilize this webpage to post future BACT determinations, source test results, data on new technologies, and emission requirements in newly approved regulations (see Supporting Data for Lowest Permitted Emission Limits for Stationary Source Equipment). When these updates are posted to the website, ARB staff will send e-mail notifications to the ARB's LCFS listserve and the California Energy Commission's Bioenergy listserve.
