None
Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources?:
No
None
A brief description of the policies and/or guidelines to improve outdoor air quality and minimize air pollutant emissions from mobile sources:
No formal policy or guideline, however we consciously select electric maintenance vehicles when replacing older internal combustion models.
None
Has the institution completed an inventory of significant air emissions from stationary sources on campus?:
Yes
None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
We track the amount and type of fuel used to generate steam from the boilers in the central heating plant, along with an estimate of the fuel used to produce electricity from our emergency generators (based on number of hours run). These figures are submitted to the state and used to calculate a fee based on our portion of the various pollutants associated with these fuels. The estimated amounts the state determines we have contributed for 2013 are indicated below.
None

None
A brief description of the institution’s initiatives to minimize air pollutant emissions from stationary sources, including efforts made during the previous three years:
Eliminated #6 fuel oil use by replacing two older dual fuel boilers with one larger one that uses natural gas as its primary fuel source and #2 fuel oil for curtailment periods.
We replace old residential boilers with high efficiency, variable speed, condensing types, which are sized to match improvements to the structures envelope (typically fewer btu's required).
