Air Quality

Under the Federal Clean Air Act, if an area within a state fails to meet any of the National Ambient Air Quality Standards (NAAQS), the state must develop a State Implementation Plan (SIP) to demonstrate how pollution will be cleaned up. Hall County was a part of a 20-county area that was designated as nonattainment for the 8-hour Ozone standard, and part of a 22-county area designated as nonattainment for the Fine Particle Particulate Matter (PM 2.5) standard. Areas that were designated nonattainment for the 8-hour ozone and PM2.5 standards must show (through a process known as transportation conformity) that their transportation activities would not conflict with State air quality goals for that area.



Hall County, subsequently, has been designated as part of a 20 County area, 8-hour ozone maintenance area. In addition, Hall County is in the process of being designated as part of a 22-county particulate matter 2.5 maintenance area. A maintenance area classification requires conformity to transportation budgets for 20 years once the region is designated as attainment. Because Hall County is but a small portion of the overall nonattainment areas, the GHMPO coordinates closely with the Atlanta Regional Commission (ARC) which functions as the Atlanta MPO and has the technical staff to carry out the modeling necessary to demonstrate air quality conformity for entire area. As part of this coordination, the GHMPO aligns its various review and approval schedules with those of the ARC whenever possible.

As part of the state's SIP, the Georgia Environmental Protection Division (EPD) has set Motor Vehicle Emissions Budgets (MVEBs) for the designated nonattainment pollutants and their precursors. The GHMPO's Long Range Transportation Plan (LRTP) and Transportation Improvement Program (TIP) are evaluated in the context of these emissions budgets, and must be determined in conformance under the air quality standards.

The most recent version of the approved Conformity Determination Report (CDR) and the accompanying CDR Addendum, which includes both Atlanta region and Hall County projects.
