# 1. Background In 2009, the Air Pollution Control Division (APC D) developed a Technical Support Document (TSD) for the Colorado Springs Carbon Monoxide Maintenance Area, which was adopted by the Colorado Air Quality Control Commission (CAQ CC) on December 17, 2009, and submitted to the U.S. Environmental Protection Agency (EPA) on March 31, 2010. The original TSD provided an annual emission inventory for carbon monoxide in Colorado Springs for the year 2007.

This document (Supplemental TSD), submitted to the EPA on August 15, 2011, serves as a supplement to the original TSD. The emission inventory in this Supplemental TSD represents 2007 average daily winter conditions as calcula ted by the APCD in 2009 and provided in the Revised Carbon Monoxide Attainment/Maint enance Plan for the Colorado Springs Attainment/Maintenance Area (adopted by th e CAQCC on December 17, 2009, and submitted to the EPA on March 31, 2010). The APCD calculate d the emission inventory for average daily winter conditions because winter weekdays traditionally provide the highest levels of carbon monoxide emissions.



# 2. Emission Inventory Methodology To calculate the emission inventory for the Revised Carbon Monoxide Attainment/Maintenance Plan (shown below), the APCD used the EPA’s MO BILE6 model and local vehicle miles traveled (VMT) data for on-road mobile source emissions , the EPA’s non-road model, local demographic information for area and off-road sources, and re ported actual emissions for point sources. MOBILE6 and non-road model inputs were used to represent 2007 av erage daily winter conditions, and as such, were calculated differently than emission inventories in the original TSD, which used inputs to reflect average annual c onditions. Heating and woodburning emissions were apportioned from annual emissions estimates by h eating degree data from the Western Regional Climate Center. Other source cate gories, including non oil and gas (O&G) point sources, aircraft, commercial cooking and railroads, were apportione d by taking the annual emission totals provided in the original TSD and dividing them by 365.
