Does the institution have policies and/or guidelines in place to improve outdoor air quality and minimize air pollutant emissions from mobile sources?:
Yes

A brief description of the policies and/or guidelines to improve outdoor air quality and minimize air pollutant emissions from mobile sources:

We are a rural campus with no through traffic, a resident student population, and little on-campus traffic. Our outdoor air quality issues are minimal. Notwithstanding, our Facilities Department makes every attempt to ensure healthy outdoor air by, inter alia, a close evaluation of fuel efficiency and emissions characteristics whenever a new vehicle is purchased. Several of our campus work vehicles are fully electric (charged by 100% renewable electric power) and the campus carpool fleet consists of hybrid sedans.


Has the institution completed an inventory of significant air emissions from stationary sources on campus?:
No

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

As part of our STARS audit, we conducted a Greenhouse Gas emissions inventory (Scopes 1,2,3), the results of which are reported in OP-1. However, the inventory only calculated CO2, N2O, CH4, and eCO2 - meaning that we have no data for the entry fields below.


Weight of the following categories of air emissions from stationary sources::
Weight of Emissions
Nitrogen oxides (NOx) 0 Tons
Sulfur oxides (SOx) 0 Tons
Carbon monoxide (CO) 0 Tons
Particulate matter (PM) 0 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

A brief description of the institution’s initiatives to minimize air pollutant emissions from stationary sources, including efforts made during the previous three years:

All of our hot water heating equipment is either gas or electric (no coal, no oil). Our furnaces and boilers use premium efficiency (90%+) equipment. With all new heating equipment we are designing for 120-140'F hot water to maximize the use of the condensing cycle on our premium efficiency boilers (as long as we stay below 140'F, the boilers stay in their condensing range, which saves about 10% on fuel). The campus uses two main boilers and four smaller boilers, 90% of the time we use the smaller ones (larger boilers are reserved for peak demand). The boiler system is staged, and software controlled. Heating has been provided by natural gas since the early 1960s.
