2008 Ozone Standard Final Designation
The US Environmental Protection Agency (EPA) has announced the Charlotte area’s final designation under the new 2008 ozone standard. The Charlotte “Metrolina” region will be a “marginal non-attainment” area; however, some parts of the region previously classified as non-attainment will now be classified as “attainment.” A non-attainment area is an area designated by the EPA that does not meet the National Ambient Air Quality Standards (NAAQS).
The Charlotte region does not meet federal air quality standards for ground-level ozone pollution. The Clean Air Act requires MUMPO to demonstrate that its Transportation Improvement Program (TIP) and Long Range Transportation Plan (LRTP) do not harm air quality. The process by which MUMPO demonstrates that the TIP and LRTP will not lead to the region exceeding established ozone standards is referred to as “conformity.”
What is Transportation Conformity?
Transportation conformity is required by the Clean Air Act (section 176(c) (42 U.S.C. 7506(c))to ensure that federal funding and approval are given to highway and transit projects that are consistent with ("conform to") the air quality goals established by a state air quality implementation plan (SIP). Conformity affects MUMPO because it is required to demonstrate that its conform to the SIP.
Conformity is an important part of MUMPO’s planning process; however, its basic components are not always understood. To help provide a better understanding of conformity, we have provided a link to a slide show prepared by the US Department of Transportation and the Environmental Protection Agency that presents a basic understanding of conformity. We encourage you to take the time to view the presentation and to learn more about this important topic.
