Canton OH Lead Redesignation Technical Support Document

The Technical Support Document presents the air quality data, monitoring information, and modeling analysis supporting EPA's determination that the Canton, Ohio area has attained the 2008 Lead NAAQS and qualifies for redesignation to attainment. The document includes reviews of ambient air quality monitoring data, emissions inventories, and projected air quality trends.\n\nAffected parties including industrial facilities in the Canton area, local governments, and Ohio EPA should review the technical analysis to understand the basis for the proposed redesignation. If finalized, the redesignation would remove certain Clean Air Act obligations associated with nonattainment status while maintaining ongoing monitoring and planning requirements.
