Abstract

Each National Ambient Air Quality Standard (NAAQS) has its own rounding convention found in 40 CFR Part 50. Although the rounding conventions are focused on monitored data, the same principles apply to modeled concentrations. It is acceptable to apply these rounding conventions to non-PSD modeled concentrations for comparison with the NAAQS.
