"---" indicates that no data was submitted for this field

Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources on campus?:
No

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

Although Princeton doesn't have a formal policy to improve outdoor air quality and minimize air pollutant emissions from mobile sources, Princeton still has a strong commitment to clean air. The TigerTransit bus fleet runs on biodiesel fuel, campus fleet vehicles include electric carts, and newer facilities vehicles are fuel-efficient.

The University is also committed to reducing air pollutant emissions through campus infrastructural improvements. These improvements include:

-Thermal distribution system improvements
-Lighting upgrades, including retrofitting most of campus lighting with LED bulbs
-Building HVAC replacements
-Existing building energy conservation projects
-Plant efficiency and run-time improvements
-Installing a 5.4 MW solar field to produce electricity
-Ground-coupled heat pumps for heating and cooling buildings
-Control system optimization


Has the institution completed an inventory of significant air emissions from stationary campus sources or else verified that no such emissions are produced?:
Yes

Weight of the following categories of air emissions from stationary sources::
Weight of Emissions
Nitrogen oxides (NOx) 59.30 Tons
Sulfur oxides (SOx) 5.82 Tons
Carbon monoxide (CO) 70.87 Tons
Particulate matter (PM) 4.82 Tons
Ozone (O3) 0 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 methodology(ies) the institution used to complete its air emissions inventory:

The University calculates its annual pollutant emissions and reports them to the New Jersey Department of Environmental Protection, as is required by the University’s Title V permit. Techniques include calculation methods with AP-42, continuous emission monitors, and fuel use records from the various sources over the calendar year.

Additional documentation to support the submission:

The weight of emissions listed for SOx reflects the emission weight for SO2
The weight of emissions listed for PM reflects the emission weight for PM-2.5

The University doesn’t report emission weights for ozone and ODCs because leaks of these pollutants are insignificant. Therefore, the emission weights for these pollutants have been entered as 0 tons/yr.
