MAPS AND TABLES

OF THE AREA DESIGNATIONS FOR

STATE AND NATIONAL AMBIENT AIR QUALITY STANDARDS

 

 

INTRODUCTION

This attachment fulfills the requirement of Health and Safety Code, section 40718 for the Air Resources Board (the Board) to publish maps that identify where one or more violations of any State or federal ambient air quality standard have been measured. Federal standards are the National Ambient Air Quality Standards promulgated under section 109 of the federal Clean Air Act (42 U.S.C. 7409).

The attachment is divided into three sections. Section A details the levels and specific requirements of both the State and the National Ambient Air Quality Standards.

Section B contains maps and tables showing the area designations for each pollutant for which there is a State ambient air quality standard (State standard). These maps and summary tables reflect the proposed amendments to the area designations that the Board will consider in 2000, pursuant to Health and Safety Code section 39608. An attainment designation indicates that pollutant concentrations in the area did not violate the State standard for that pollutant, excluding exceedances affected by highly irregular or infrequent events as defined in Appendix 2 to the designation criteria. A nonattainment designation indicates that a pollutant concentration did violate the State standard at least once during the previous three calendar years. Again, exceedances affected by highly irregular or infrequent events are not considered as violations. An unclassified designation indicates that air quality and other relevant information is insufficient to determine whether the area is attainment or nonattainment. In addition to these three major designation categories, there is a subcategory of the nonattainment designation called nonattainment-transitional. This subcategory applies to nonattainment areas that are close to attainment and meet other conditions as specified in the designation criteria.

Section C contains maps and summary tables showing the most current area designations for each pollutant for which there is a national ambient air quality standard (national standard). These area designations have been promulgated as final by the United States Environmental Protection Agency (U.S. EPA) based on the requirements in section 107(d) of the Clean Air Act as amended in 1990 (42 U.S.C. 7407(d)). The national designations are made by the U.S. EPA on a different review schedule than the designations for the State standards. Further information on the area designations for the national standards may be obtained by contacting the U.S. EPA, or visiting the agency’s air quality maps web site at: http://www.epa.gov/region09/air/maps/maps_top.html.

The maps in Sections B and C will also be available at this ARB web site: http://www.arb.ca.gov/desig/adm/adm.htm.

 

A. State and National Ambient Air Quality Standards

The Board has adopted and the U.S. EPA has promulgated ambient air quality concentration levels that define good air quality. These levels are the ambient air quality standards and were established to protect human health and/or welfare. The levels of the State and national standards may differ because the Board and the

U.S. EPA considered different bodies of information, and the Board chose to provide a wider margin of safety in the State standards than did the U.S. EPA in the national standards.

An ambient air quality standard is a concentration level expressed in either parts per million or micrograms per cubic meter and averaged over a specific time period such as one-hour, eight-hours, 24-hours, or one-year. The different averaging times and concentrations are meant to protect against different exposure effects. Some ambient air quality standards are expressed as a concentration that is not to be exceeded. Others are expressed as a concentration that is not to be equaled or exceeded.

The national standards are further categorized as primary standards and secondary standards. The primary national standards are meant to protect public health. The secondary national standards are meant to protect the public welfare from any known or anticipated adverse effects of the pollutant.

The following table lists the applicable pollutant levels, averaging times, and analytical measurement methods for both the State standards and the national standards, including the new national ozone, PM10, and PM2.5 standards promulgated by the U.S. EPA in July 1997. Because these new national standards are the subject of ongoing legal challenges and their status may change due to future court proceedings, interested persons should contact U.S. EPA for the current status of the new standards, or visit its web site at: http://www.rtpnc.ephttpa.gov/naaqsfin.

B. Area Designations for the State Ambient Air Quality Standards

This section contains a description of the area designations for each pollutant for which there is a State ambient air quality standard listed in the California Code of Regulations, title 17, section 70200. The information presented reflects the proposed amendments to the area designations that the Board will consider in 2000.

The area designations for each pollutant are presented in the form of a map and a summary table. Areas are identified as attainment, nonattainment, nonattainment-transitional, or unclassified for each pollutant, as shown below:


Attainment;A

Nonattainment;N

Nonattainment-Transitional;NT

Unclassified;U

Generally, the Board designates areas by air basin or county. However, when there are areas within an air basin or county with distinctly different air quality deriving from sources and conditions not affecting the entire air basin or county, the Board may designate a smaller area. Generally, when the boundaries of the designated area differ from the air basin or county boundaries, the description of the specific area is referenced at the bottom of the summary table.
