Yes
None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
The SJU Office of Sustainability completed an inventory of significant air emissions from on-campus stationary sources for fiscal year 2014 (July 2013-June 2014). The calculations were made using estimations from a calculator provided on the Illinois Environmental Protection Agency's website. During FY2014, two fuel sources were used in the cogeneration power facility at Saint John's: natural gas and #2 fuel oil. The portion of the power plant's FY2014 operations included 1,695,136 therms of natural gas and 35,063 gallons of #2 fuel oil. The emissions were calculated individually, the totals were added together, and the combined data is reported below.
None
Weight of the following categories of air emissions from stationary sources::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 8.83 Tons |
| Sulfur oxides (SOx) | 2.54 Tons |
| Carbon monoxide (CO) | 7.21 Tons |
| Particulate matter (PM) | 0.68 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 |

Data source(s) and notes about the submission:
The only sulfur oxide accounted for by this calculator was sulfur dioxide (SO2). The calculator also does not provide emissions data for ozone (O3), lead (Pb), hazardous air pollutants (HAPs), or ozone-depleting compounds (ODCs). The calculator did provide annual emissions estimates for ammonia (NH3; 0.2852 tons/year) and volitile organic material (VOM; 0.4706 tons/year).
The data for particulate matter was further broken down by size of the particle. Total PM equaled 0.6793 tons/year, PM10 totaled 0.6617 tons/year, and PM2.5 totaled 0.6486 tons/year. As expected, the vast majority of PM emissions were smaller than 2.5 microns in diameter. Larger particles are more easily captured by emissions control technologies.
Nitrous oxide data is further broken down also. Total NOX emissions are estimated at 8.8263 tons/year. Just 0.1884 tons of that quantity is made of NO2.
