        Mobile sources: HC, CO, PM-10, NOx

76) Has your campus initiated programs to reduce air pollutants form stationary sources?
The campus has initiated a program to reduce TSP from construction activities and to capture Freon from refrigeration equipment.  The campus also has a policy to purchase electric cars instead of gas and diesel fueled vehicles to reduce mobile source pollution. 

77) What kinds of ozone-depleting compounds are used on campus and what are the sources?
The campus generates hydrocarbons from painting operations and Freon from refrigeration equipment. 

78) Are any programs in place to recapture ozone-depleting compounds or find safer alternatives?
