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:
E85 and biodiesel vehicles and fuel pumps.
Anti-idling policy.
Fare free buses to minimize vehicle use.
Parts runner to minimize travel by shop personnel.
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:
1. CEMS direct measurements
2. Performance stack testing measurements and flow data to determine mass rates
3. EPA emission factors (AP42) and fuel use data
Weight of the following categories of air emissions from stationary sources::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 373 Tons |
| Sulfur oxides (SOx) | 189 Tons |
| Carbon monoxide (CO) | 55 Tons |
| Particulate matter (PM) | 12 Tons |
| Ozone (O3) | 0 Tons |
| Lead (Pb) | 0.00 Tons |
| Hazardous air pollutants (HAPs) | 8 Tons |
| Ozone-depleting compounds (ODCs) | 0.01 Tons |
| Other standard categories of air emissions identified in permits and/or regulations | 252,846 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:
The UNCCH Cogeneration Facility uses a fluidized combustion bed boiler with lower combustion temperatures, i.e., 1450 - 1700 degrees Fahrenheit to reduce NO and NO2 gases emissions and utilizes calcium carbonate dry sorbent injection to reduce SO2 emissions. The Cogeneration facility also uses a state of the art baghouse to capture particulate emissions and meet air quality standards. UNCCH monitors operation and maintenance of emergency generators (EGs) on campus and replaces the older EGs with newer, lower emission EGs regularly.
