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) 3.60 Tons
Sulfur oxides (SOx) 0.26 Tons
Carbon monoxide (CO) 4.29 Tons
Particulate matter (PM) 0.31 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 1.05 Tons

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

Swarthmore College is governed by a State Operating Permit that requires an annual emissions inventory for all campus stationary equipment to be compiled for the calendar year. The methodology is to utilize emission factors provided by either the AP-42 table approved by the EPA, factors provided by Pennsylvania DEP or factors that have been determined by direct exhaust stream testing of equipment. Those factors are the multiplicands for a given unit of fuel to determine the emissions from a specific source.

Other standard categories of air emissions identified in permits and/or regulations: 0.026 tons ammonia; 0.40 tons VOCs; 0.00 tons antimony; 0.00 tons arsenic; 0.0002 tons barium; 0.0001 tons benzene; 0.094 tons butane; 0.0001 tons cadmium; 0.0017 tons chloride; 0.0001 tons chromium; 0.00 tons copper; 0.14 tons ethane; 0.00 tons ethyl benzene; 0.0002 tons fluoride; 0.0033 tons formaldehyde; 0.081 tons hexane; 0.00 tons hexavalent chromium; 0.00 tons maganese; 0.00 tons mercury; 0.11 tons methane; 0.00 tons methyl chloroform; 0.00 tons molybdenum; 0.00 tons napthalene; 0.0005 tons nickel; 0.12 tons pentane; 0.00 tons phosophorus; 0.072 tons propane; 0.00 tons selenium; 0.0002 tons toluene; 0.0003 tons vanadium; 0.0010 tons zinc; 0.00 tons o-xylene
