1 INTRODUCTION 

This Appendix contains emission summary tables for the Charlotte-Gastonia-Rock Hill, NC-SC 

nonattainment area, all of North Carolina’s counties, all of South Carolina’s Counties and for the 

Association for Southeastern Integrated Planning (ASIP) states. The ASIP states include 

Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee, 

Virginia and West Virginia. All the emissions are representative of a typical summer weekday. 

During the mid 1990s a regional modeling effort was undertaken called Ozone Transport 

Assessment Group (OTAG). This project combined the efforts of the states in the mid-west and 

in the northeast and southeast, as well as the US Environmental Protection Agency and industry 

stakeholders. During this modeling, it was decided to use Thursday emissions as “typical” 

weekday emissions since Friday emissions tend to have higher emissions and Monday emissions 

tend to be lower. All those involved in OTAG accepted this reporting standard. 

The North Carolina Division of Air Quality adopted this standard for ease of reporting and 

Thursday emissions were used for the baseline and attainment year inventories. Since the 

modeling was for the period May through September, a July Thursday was chosen to represent 

the typical summer weekday emissions. The emissions may vary by day of the week depending 

on temperature and daily activity distribution, but Thursday emissions are generally accepted as 

“typical” summer weekday emissions in the modeling community. 

The emission summaries are obtained from the emissions modeling reports, which report whole 

county emissions. For two counties, Iredell County, NC, and Your County, SC, only portions of 

each county were included in the designated nonattainment area. The emissions for just the 

nonattainment area portion of the two counties are not easily determined. Although a population 

ratio of nonattainment area to whole county population is often used to adjust area source 

emissions, this would not make sense for point and highway mobile sources. To be consistent 

between all source sectors, the nonattainment area emissions tables contain the whole county 

emissions for both Iredell and York Counties. 

2 FUTURE YEAR (2011) EMISSION SUMMARIES 

The emissions are reported as tons/day of pollutant. The emission summary tables below are in 

the following order: 

• 2011 Nonattainment Area Emissions 

• 2011 North Carolina Counties Emissions 

• 2011 South Carolina Counties Emissions 

• 2011 ASIP States Emissions 

• Biogenic Episode Emissions Summary for Metrolina Nonattainment Counties
