Swarthmore College
OP-2: Outdoor Air Quality

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
