The Department of Toxic Substances Control protects public health and the environment by regulating hazardous waste management activities, overseeing and performing cleanup activities at sites contaminated with hazardous substances, encouraging pollution prevention and developing environmental protection technologies, and providing regulatory assistance and public education.

Department programs drive the need for infrastructure investment. Thus, each department has a related capital outlay program to support this need. For the specifics on the Department of Toxic Substances Control's Capital Outlay Program, see "Infrastructure Overview."
