### Executive Summary

On March 12, 2008, the U.S. Environmental Protection Agency promulgated the new ozone standard of 0.075 ppm. Pursuant to the Clean Air Act, the states have one year from issuance of the new standard to

recommend areas of the state as nonattainment or attainment with the new standard. This technical

summary document present s the State of Tennessee’s recommendations. As deta iled in Table 1, the State

of Tennessee recommends 1 5 counties be designated nonattainment including one county partially with the new ozone standard and the remaining 80 counties be designated as attainment. These

recommendations are based on the Nine

- Fa ctor analysis, which was outlined in the EPA guidance dated December 4, 2008. The State of Tennessee evaluated the counties shown below (Figure S) in each metropolitan statistical area (MSA). The following is a summary of each MSA.

inclusion/exclusion evaluation for the Chattanooga MSA 8

- hour ozone nonattainment area. These factors include precursor emissions, air quality data, population, urbanization, commuter /traffic patterns (―connectivity‖), meteorology, growth, and jurisdictional boundaries. All factors in the applicable EPA guidance were considered.



### Hamilton County

Recommendation: nonattainment Jurisdictional boundaries: Hamilton County was previousl y classified as attainment for ozone. Air Quality Data: There are two ozone monitors in Hamilton County. Both ozone monitors in Hamilton County showed a design value for 2006

- 8 data that is greater than the new standard of 0.075 ppm.
Emissions: 17,533 tons per year of NO

x and 19,880 tons per year of VOC. Only 15.6% of NOx emissions are from point sources, 78.3% from mobile sources and 6% from area sources. VOC emissions are split primarily between area sources (52.5%) and mobile (39%) sources. Popula tion: 330,168 people and 568.1 people per square mile

. Traffic: 9,986,801 DVMT

. Growth: The population grew 7.2% between 2000 and 2007. The DVMT grew 15% between 2000

and 2007. Meteorology: The winds are climatologically from the south, southwest, and south

- southwest. Geography/topography: Most of County is located in the Valley and Ridge Geographic Region. The topography of the Valley and Ridge consists of long linear ridges and parallel lowland valleys that

trend in a northeast to southwest direction . The ridges usually have high elevations of 1100 to 1500 feet while adjacent valley floors vary from 700 feet to 1000 feet. A thin north

- south strip of the County is located in the Cumberland Plateau Region having a different topography, like in places, the surface has been cut by stream valleys and precipitous gorges that are 200 to 400 feet deep. Level of control of emissions sources: There are 76 point sources in Hamilton County that reported for the Hamilton County local program. Control information not available at this time. Stage 1 vapor recovery is required for gasoline dispensing facilities.

Summary: The TAPCD recommends that Hamilton County be designated as nonattainment for Ozone. The County contribution to the Chattanooga MSA remains to be de termined for the entire MSA, which includes counties from Georgia. For the three county TN part of Chattanooga MSA, the county contribution for VOC is 20%, of which the majority (68%) is from mobile sources. It is to be noted that the point source emissio n contribution of VOC to the MSA emission level is less than 3%

. About 88.8% of the population, 81.3% of the DVMT contributes to the three county TN part of the MSA. The population density is 568.1 per square 

### mile. The county is a mixed urban (City of C hattanooga) and mostly sparsely populated mountainous region.Tennessee 8

The coun ty does not have a representative ozone monitoring and its contribution to the nearest violating monitor in Sullivan County is minimal as it is located downwind from those monitors (West and Northwest) in a predominately southwesterly wind vectors impactin g the monitors. This county is in a rural and agrarian environment. The county VOC emission contribution (18%) to the Kingsport

- Bristol MSA is the lowest. This county has the lowest population (27%), population density (117.4), and VMT (22%) for the Kingsp ort

- Bristol MSA.

### Sevier County

Recommendation: Nonattai nment. Air Quality Data: Clingmans Dome () monitor in violation of the standard (2005

- 07 design value

– 0.084 ppm; 2006

- 08 design value

– 0.084 ppm). Emissions: 559 tons per year of NO

x and 2,371 tons per year of VOC (2005 NEI). Mobile source

emissions generate the majority of NOx (91%) and VOC (97%) of all emissions from this county. Population: 83,527 people (2007) and 141.1 people per square mile. Traffic: High VMT (3,453,187 VMT/day). Growth: The population grew 17.4% between 2000 and 2007. Th e VMT grew 32% between 2000

and 2007. Meteorology: The winds are climatologically from the southwest, west

- southwest, and south

southwest. Geography/topography: Developing touristic area. Ridge and Valley topography covers the western portion and Unaka S moky Mountains cover the eastern portion of the state. The Great Smokies National Park () area is located across several counties in Tennessee and North Carolina. Jurisdictional boundaries: Entire County by itself.

Level of control of emissions sources: There are no point sources in the county that reported for the 2005 NEI. Since 2005, the TAPCD requires the application of low NOx burner (LNB) technology at new and certain modified sources for NOx control. There is currently no I/M program. Stage I v apor recovery is required for gasoline dispensing facilities. Additionally, there are no industrial point sources of emissions in the park proper with an unknown portion of each county’s respective mobile

source contributions for NOx and VOC. Ozone monito ring within the park at high elevations sites (Clingmans Dome) demonstrates a profound difference from those at lower elevation (Cades Cove

monitor: 2005

COUNTY BY COUNTY SUMMARY

The following is a county

- by

- county summary of the factors that were considered in the

inclusion/exclusion evaluation for the Meigs County 8

- hour ozone nonattainment area. These factors include precursor emissions, air quality data, population, urbanization, commuter/traffic patterns (―connectivity‖), meteorology, growth, and jurisdictional boundaries. All factors in the applic able EPA guidance were considered.



### Meigs County

Recommendation: Nonattainment Air Quality Data: There is one ozone monitor in Meigs County. The ozone monitor shows a design

value for 2006

- 8 data that is greater than the new standard of 0.075 ppm.

E missions: 1,769 tons per year of NO

x and 935 tons per year of VOC. The majority (98%) of the NOx emissions are from mobile sources. VOC emissions are split primarily between area sources (25%) and mobile (75%) sources. Population: 11,657 people and 56.9 people per square mile.
Traffic: 278,982 DVMT Growth: The population grew 5.2% between 2000 and 2007. The VMT grew 10% between 2000 and

2007. Meteorology: Based on data from Chattanooga, the winds are climatologically from the south and

north.
Geograp hy/topography: Meigs County is located in the Ridge and Valley region of Tennessee. Jurisdictional boundaries: Meigs County is currently classified as attainment. Level of control of emissions sources: There is one point source in Meigs County that repo rted for the 2005 NEI. However, NOx and VOC are not emitted by this source. There is currently no I/M program. Stage 1 vapor recovery is required for gasoline dispensing facilities. Summary: The TAPCD recommends that Meigs County be designated as Nonat tainment. This designation is based almost entirely on the fact that the ozone monitor shows nonattainment with the new standard. Due to the prevailing wind direction from the south, emissions from the Chattanooga area are probably causing the high ozone readings in Meigs County. If the ozone monitor in Meigs County shows a design value for 2007

- 9 data that is attaining the standard, then the TAPCD would change the recommendation to attainment. Meigs County has a small population and a small population density. Meigs County has a moderate growth rate. Meigs County had only one point source that reported for the 2005 NEI, and there are only a few minor point sources in the county.
