1. Emission Inventory Methodology 

The Air Pollution Control Division (APCD) developed the 2007 emission inventory in the 

"Carbon Monoxide Maintenance Plan for Colorado Springs" using U.S. Environmental Protection 

Agency (EPA) approved emissions modeling methods, including EPA's MOBILE6 model and the 

latest transportation data from the Colorado Department of Transportation (CDOT) and 

demographic data from the State Demographers Office. 

Highway mobile source emissions are from the EPA model MOBILE6, an emission factor model 

for predicting gram per mile emissions of Hydrocarbons (HC), Carbon Monoxide (CO), Nitrogen 

Oxides (NOx), Carbon Dioxide (C02), Particulate Matter (PM), and toxics from cars, trucks, and 

motorcycles under various conditions. 

Non-road source emissions are from the EPA Non-Road Model. 

Area source emissions (including heating, construction, railroads, etc.) are from the 2002 EPA 

National Emissions Inventory (NEI), grown to 2007 by population growth from data from the 

State. For more documentation for these categories, refer to the NEI documentation (EPA, 2008). 

Under Air Quality Control Commission Regulation No.3, the APCD requires any source that 

emits two tons per year or greater to submit an Air Pollutant Emission Notice (APEN) (APCD, 

2008). This means that sources that emit less than two tons per year are not necessarily accounted 

for in an emissions inventory. The point source emissions for Colorado Springs were obtained 

from this tracking system. The emission estimates are made using a variety of methodologies. 

Data from source-specific emission tests, or continuous emission monitors are preferable, but not 

always available. The EPA has developed a variety of emission factors to estimate emissions as 

well. Emission factors are frequently the best or only method available for estimating emissions.
