Chemical Waste Disposal

EH&S is responsible for the collection of hazardous chemical waste for the University, including all campuses and off-site locations. Hazardous chemical waste is defined as any liquid, gaseous, or solid chemical that is ignitable, corrosive, reactive, toxic, or persistent, and is no longer useful or wanted.

According to Administrative Policy Statement 11.2, organizational units and departments cannot contract with an outside vendor to collect hazardous waste.

There is no charge for hazardous chemical waste collection, except for unknowns and unstable peroxide forming chemicals
