We have made our best effort to ensure that the data contained in these reports is accurate. We note that there may be brief delays in
updating the reports as we receive new state submissions and we take rulemaking action on plans. In order to assist us in providing
accurate information, we request that you contact us by clicking on the "Contact Us" link near the top of this page with any comments
regarding or corrections to the posted information, including concerns about whether the entries reflect the most recent status. Current and historical design value data can be found on the EPA Air Quality Design Values website and the EPA Green Book contains comprehensive nonattainment area, designation status, and historical information. The level of the 1-hour NAAQS for sulfur dioxide is 75 parts per billion (ppb) calculated as the 3-year average of the 99th percentile of the annual distribution of daily maximum 1-hour average concentrations. |
