The Air Resources Board (the Board or ARB) will conduct a public hearing at the time and place noted below to consider approving a revision to the State Implementation Plan (SIP) for Carbon Monoxide (CO). The revision consists of an update to the CO maintenance plan (Plan) for ten urban areas that have attained the federal air quality standard for CO since the early 1990s: Bakersfield, Chico, Fresno, North Lake Tahoe, South Lake Tahoe, Modesto, Sacramento, San Diego, San Francisco Bay Area, and Stockton. The staff's proposed Plan shows how all of these areas will continue to maintain the standard through 2018. It updates emissions estimates and establishes new on-road motor vehicle emission budgets for transportation conformity purposes.
