Question 2
• In accordance with the National Ambient Air Quality Standards (NAAQS) and procedures developed
by the Air Quality Division of the Department of Health of the DC Government (DC AQD, 2003),
results concluded that the carbon monoxide emission rate for the new facility will be 24 grams/day,
which is a minimal 0.08% increase from existing conditions. The modeled emission rate increase due
to our new facility and resultant maximum predicted concentration increase of 0.38 ppm for 1-hour
and 0.18 ppm for 8-hour averages for the entire neighborhood, shows that the total net
concentration impact is well within the acceptable 1-hour and 8-hour ambient concentrations per
NAAQS and DC AQD 2003.
• There will not be a noticeable difference in the surrounding area or poorer air quality, because of the
very minimal increase in carbon monoxide emissions and resultant concentrations, which the DC
AQD has defined in their modeling guidelines as a proxy for all other pollutants from motor vehicles.
