Hazardous Waste Findings

CalEnviroScreen 4.0 Hazardous Waste values are used to evaluate the environmental effects in census tracts due to the presence of hazardous waste, which is calculated as the sum of weighted permitted hazardous waste facilities, hazardous waste generator sites, and chrome plating facilities within each census tract.  Data was obtained from the EnviroStor Hazardous Waste Facilities Database and the Department of Toxic Substances Control (DTSC)’s Hazardous Waste Tracking System.  Permitted hazardous waste facilities data was downloaded by OEHHA in July 2021, hazardous waste generator data are from 2018 to 2020, and chrome plating facilities data are based on a survey from 2018. (OEHHA 2021a, page 126)

“Hazardous waste contains chemicals that may be harmful to health. Only certain facilities are allowed to treat, store or dispose of this type of waste. Hazardous waste can range from used automotive oil to highly toxic waste materials produced by factories and businesses. Hazardous waste is transported from businesses that generate waste to permitted facilities for recycling, treatment, storage or disposal.” (OEHHA 2021b)

“Studies have found that hazardous waste facilities are often located near poor neighborhoods and communities of color.  Hazardous waste facilities often are cause for concerns about effects on health and the environment in the communities where they operate.” (OEHHA 2021b)
