  3. Title: Carbon Monoxide: California State Area Designations, 2008-2011

    Contributors:

    Summary: This polygon shapefile contains area designations of carbon monoxide (CO) levels in California as required under Health and Safety Code section 39608. The designations are consistent with the criteria established in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof. There are four possible designation categories: attainment, nonattainment, nonattainment-transitional, and unclassified. Nonattainment areas are geographic areas which have not met National Ambient Air Quality Standards for Carbon Monoxide air pollution. In addition, CO nonattainment areas have been assigned a classification, commensurate with the severity of their air quality problem, under Health and Safety Code section 40921.5. The State area designations are reviewed annually and approved by the State Air Resources Board. Projection: Teale Albers, NAD83 This shapefile can be used to identify state carbon monoxide pollution area designations from the prior three-year period (2008-2011) in accordance with the California State Ambient Air Quality Standard. U.S. Environmental Protection Agency. (2011). Carbon Monoxide: California State Area Designations, 2008-2011. California Air Resources Board. Available at: http://purl.stanford.edu/st637td0472. The State area designations are reviewed annually and approved by the State Air Resources Board. In 2011, staff did not propose any changes to the State carbon monoxide designations.

  4. Title: Visibility Reducing Particles: California State Area Designations, 2008-2011

    Contributors:

    Summary: This polygon shapefile shows area designations in California as required under Health and Safety Code section 39608 for ozone, nitrogen dioxide, sulfur dioxide, lead, and visibility reducing particles. Visibility-reducing particles consist of suspended particulate matter, which is a complex mixture of tiny particles that consists of dry solid fragments, solid cores with liquid coatings, and small droplets of liquid. These particles vary greatly in shape, size and chemical composition, and can be made up of many different materials such as metals, soot, soil, dust, and salt. The designations are consistent with the criteria established in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof. There are three possible designation categories for lead (attainment, nonattainment, and unclassified), and there are four possible designation categories for ozone, nitrogen dioxide, sulfur dioxide, and visibility reducing particles (attainment, nonattainment, nonattainment-transitional, and unclassified). In addition, ozone nonattainment areas have been assigned a classification, commensurate with the severity of their air quality problem, under Health and Safety Code section 40921.5. The State area designations are reviewed annually and approved by the State Air Resources Board.

The State area designations are reviewed annually and approved by the State Air Resources Board. In February 2011, the staff proposed a number of changes for ozone. The Board approved the proposed changes at a public hearing in May 2011. The Office of Administrative Law (OAL) approved and filed the 2011 State Area Designations rulemaking on September 8, 2011. The regulations became effective on October 8, 2011. Updated: 11/28/11 This layer is presented in the WGS84 coordinate system for web display purposes.

  6. Title: California Air Basins, 2004

    Contributors:

    Summary: The California Air Basins layer is a polygon shapefile coverage representing the 15 California air basins, as defined in state statute and regulation. This data layer shows the air basin boundaries and their names, as of March 2004. Air Basins are designated pursuant to California statute and regulation. See the California Health and Safety Code, Section 39606 et seq. and California Code of Regulations, Title 17, Section 60100 et seq. Air Basins identify regions of similar meteorological and geographic conditions and consideration for political boundary lines, and are related to air pollution and its transport.
