The offices of the University's Environmental Health and Safety staff are located in two locations: at the Environmental Safety Facility (ESF) in the BioResearch Center complex off Spear St,and on main campus at 284 East Ave. The ESF has a "Part B" permit from the state which allows storage of hazardous waste there for up to a year. This allows the University to take advantage of more cost-effective methods of waste disposal and provide better chemical safety services to the employees.
