Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources?:
A brief description of the policies and/or guidelines to improve outdoor air quality and minimize air pollutant emissions from mobile sources:
Our Physical Plant Department has a no idling policy for its entire fleet. We also have signage at all loading docks to prevent contractors and shippers from idling. Lastly, when replacing vehicles in our fleet, we select new models with higher fuel efficiency and fewer emissions.
Has the institution completed an inventory of significant air emissions from stationary sources on campus?:
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
In compliance with EPA and Maine DEP regulations, Colby regularly monitors and applies for licenses for all of our air emissions from each of our nine major stationary sources.
Weight of the following categories of air emissions from stationary sources::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 25.60 Tons |
| Sulfur oxides (SOx) | 8.70 Tons |
| Carbon monoxide (CO) | 7.20 Tons |
| Particulate matter (PM) | 2.20 Tons |
| Ozone (O3) | --- |
| Lead (Pb) | 0.00 Tons |
| Hazardous air pollutants (HAPs) | 0.08 Tons |
| Ozone-depleting compounds (ODCs) | 12.30 Tons |
| Other standard categories of air emissions identified in permits and/or regulations | 0.20 Tons |
A brief description of the institution’s initiatives to minimize air pollutant emissions from stationary sources, including efforts made during the previous three years:
In 2011 Colby opened a biomass plant which has state-of-the-art emission reduction technologies (such as an electro-static precipitator), which supplies 90% of the College's steam and 10% of our electricity. We also have an initiative to replace all of our remaining oil usage at the steam plant with natural gas, which is cleaner burning than oil.
