Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources?:

A brief description of the policies and/or guidelines to improve outdoor air quality and minimize air pollutant emissions from mobile sources:

CSU Police ticket and enforce the Colorado policy (42-4-1206 co. statute) prohibiting idling.

In addition, CSU has committed to retaining the core of campus as a Pedestrian campus & restricting vehicular access through campus policies. These policies are central to campus character & safety, but also critical to preserving high air quality standards in these areas. One of the components of furthering this strategy is the new "Around the Horn" bus service that has been funded jointly by ASCSU (student government) and the university administration. This service provides transportation around campus and reduces vehicle trips within campus boundaries.

Has the institution completed an inventory of significant air emissions from stationary sources on campus?:

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

CSU owns and operates numerous stationary sources of air emissions including boilers, generators and incinerators. Many of these sources are covered by an air emission permit or Air Pollution Emission Notice (APEN). CSU calculates air emissions from boilers using the type and amount of fuel consumed, and applying emission factors from AP-42 or based on manufacturer information. Emissions from generators are calculated based on actual run-time and manufacturer supplied emission factors. Incinerator emissions are estimated based on fuel type, allowable charge rate, and emission factors from AP-42.

Weight of the following categories of air emissions from stationary sources::
Weight of Emissions
Nitrogen oxides (NOx) 118.90 Tons
Sulfur oxides (SOx) 3.10 Tons
Carbon monoxide (CO) 49 Tons
Particulate matter (PM) 6.60 Tons
Ozone (O3) 3.80 Tons
Lead (Pb) 0 Tons
Hazardous air pollutants (HAPs) 0 Tons
Ozone-depleting compounds (ODCs) 0 Tons
Other standard categories of air emissions identified in permits and/or regulations 0 Tons

A brief description of the institution’s initiatives to minimize air pollutant emissions from stationary sources, including efforts made during the previous three years:

Initiatives in the last three years that have helped to reduce air emissions from stationary sources include the following:

• Retrofitting the boiler system at the Fisheries lab in order to improve the efficiency of operation. The boiler was short cycling, so a tank was added to lengthen time between on/off intervals thus reducing emissions from multiple starts.

• Evaluation of the incremental increase in air pollutants emitted with each major project that represents additional air emissions, e.g. cogeneration, large biomass, etc. Some projects have been shelved due to air emissions considerations. Evaluation of alternative sources to provide heat on campus that do not increase air emissions, such as geothermal energy.

- Retrofitting several residence hall facilities (originally built in the 1950s & 1960s) to dramatically improve the R value of the building skin. Energy used for heating the buildings was cut by nearly 40% thus reducing pollutants associated with burning natural gas for heat. - Coordination with Xcel Energy for the installation of electrical substation, and construction of underground electrical lines on Foothills campus to make the power more reliable and reduce reliance on standby generators
