2008 Lead Standards — Region 6 Final Designations

States submitted an initial round of recommendations to the EPA for lead attainment and nonattainment in 2009. Some states submitted additional recommendations in 2010 based on more recent or new monitoring data.

The EPA completed lead designations in two rounds. In the first round, the EPA designated as “nonattainment” any area that violated the 2008 lead standards based on data from 2007-2009.

The EPA took an additional year to make final designations decisions for all other areas of the country to allow additional lead air quality data to be collected and evaluated. In the second round, the EPA designated those remaining areas as meeting or not meeting the 2008 lead standards based on data from 2008-2010.

Tribal information is available on the Tribal Recommendations page.
