Abstract:

On July 8, 1993, the California Air Resources Board (Board) approved Resolution 93-49, thereby endorsing the progress reporting indicators presented in this report. At that time, the Board directed the staff to incorporate into the report, a clarification of the Board's policy regarding the use of the progress reporting indicators.

The clarification has been incorporated into the report, the title has been changed (from "Proposed Guidance for Using Air Quality-Related Indicators in Reporting Progress in Attaining the State Ambient Air Quality Standards" to "Guidance for Using Air Quality-Related Indicators in Reporting Progress in Attaining the State Ambient Air Quality Standards"), and the revised report has been dated September 1993. In general, the revised report clarifies that although the Board recommends reporting documented progress at the 95 percent confidence level, the districts may report documented progress at other levels of confidence (for example, 90 percent, 80 percent, or 50 percent confidence).
