Table 7-5: North Carolina Air Quality Nonattainment Areas for Carbon Monoxide (CO)
| County | Area | Nonattainment in year | Redesignation to attainment | Classification | Part or whole county | Population (2000) |
|---|---|---|---|---|---|---|
| Durham | Raleigh-Durham | 95 | 9/18/95 | Moderate <= 12.7ppm | Whole | 223,314 |
