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?:

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

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

Weight of the following categories of air emissions from stationary sources::
Weight of Emissions
Nitrogen oxides (NOx) 7.21 Tons
Sulfur oxides (SOx) 0.15 Tons
Carbon monoxide (CO) 7.75 Tons
Particulate matter (PM) 0.40 Tons
Ozone (O3) ---
Lead (Pb) 0 Tons
Hazardous air pollutants (HAPs) 0.18 Tons
Ozone-depleting compounds (ODCs) 0.00 Tons
Other standard categories of air emissions identified in permits and/or regulations ---

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

The Williams College Safety and Environmental Compliance department completes an annual greenhouse gas emissions report that includes mobile and stationary sources. One component of this is compiling the fuel usage of all sources from invoices. They also check generator runtime. With those data, an emissions factor generated from either a stack test or the AP42 emissions test (from EPA) can then provide the emissions for each of these pollutants.

Additional documentation to support the submission:

Ozone is not a reportable number because it is created in the atmosphere with sunlight - while we can track ozone-depleting compounds, we cannot/do not track ozone as an emission.
