Air Quality Improvement Efforts in Upstate South Carolina
In the early 2000s, an Early Action Compact (EAC) allowed the counties of Anderson, Greenville, and Spartanburg to develop and implement a series of activities toward achieving emissions reductions under the 1997 standards established by the U.S. Environmental Protection Agency (EPA) for air quality, ground level ozone. By signing the compact, the three counties viewed their participation in the EAC as a proactive means of achieving compliance with the 1997 8-hour ground level ozone standard ahead of the federally-mandated compliance date, while avoiding unnecessary and burdensome federal restrictions that normally apply to non-attainment areas. The implemented strategies achieved required milestones included in the EAC before December 31, 2007.
In early 2008, EPA designated 13 areas, including the Greenville-Spartanburg-Anderson area, as attaining the 1997 8-hour ground level ozone standard under the EAC. EPA proposed "this action because each of the areas has demonstrated that they attained the standard by Dec. 31, 2007".
In March 2008, the EPA Administrator announced that the agency had strengthened the 8-hour ozone standard from 0.08 parts per million (ppm) to 0.075 ppm for both the primary and secondary standards.
In January 2010, EPA announced a proposal, "Reconsideration of the National Ambient Air Quality Standard for Ozone", to further strengthen the 8-hour ozone standard below the 0.075 ppm level previously set in 2008. EPA proposed to set the new ozone standard between the 0.060-0.070 ppm range. EPA postponed the final ruling several times until the White House requested EPA the withdrawal of the draft Ozone National Ambient Air Quality Standards. In September 2011, President Obama issued the following statement:

For Immediate Release
On May 21, 2012, the EPA published the final rules for the Implementation of the 2008 National Ambient Air Quality Standards for Ozone (click here to read the final implementation rule) and for the Air Quality Designations for the 2008 Ozone National Ambient Air Quality Standards (click here to read the final designations rule). With the exception of the Rock Hill, SC, area, the entire State of South Carolina has been designated as an "unclassifiable/attainment" area. Click here to view the Map of Final Designations - EPA Region 4 (Southeast area). Click here to learn more about the final designations throughout the country. These designations became effective July 20, 2012.
As required by the Clean Air Act, EPA will "review and, if necessary, revise air quality standards every five years to ensure that they protect public health with an adequate margin of safety". Accordingly, it is expected that EPA would propose an action and finalize any necessary revisions to 2008 ozone NAAQS in the next few years. Greenville County has joined the Upstate SC regional efforts to continue improving air quality.
