Department of Toxic Substances Control - Envirostor Public Data Export

This Feature Layer Collection contains publicly shared data from Envirostor, the Department of Toxic Substances Control's Project Management Solution. The data includes Cleanup Sites, Hazardous Waste Sites, and Inspection, Compliance and Enforcement sites. Cleanup Sites: DTSC conducts and supervises investigation and cleanup actions at sites where oil or hazardous chemicals have been or may be released into the environment. Cleanup activities take place at active and abandoned waste sites, federal and state facilities and properties, and where any storage tanks have leaked. DTSC, federal and other state agencies or municipalities, or the company or party responsible for the contamination may perform cleanups. Cleanup can also include site reuse and redevelopment. Hazardous Waste Sites: Hazardous waste management facilities receive hazardous wastes for treatment, storage or disposal. These facilities are often referred to as treatment, storage and disposal facilities, or TSDFs, and their activities are described in more detail below: Treatment - Using various processes, such as incineration or oxidation, to alter the character or composition of hazardous wastes. Some treatment processes enable waste to be recovered and reused in manufacturing settings, while other treatment processes dramatically reduce the amount of hazardous waste. Storage - Temporarily holding hazardous wastes until they are treated or disposed. Hazardous waste is commonly stored prior to treatment or disposal, and must be stored in containers, tanks, containment buildings, drip pads, waste piles, or surface impoundments that comply with the Resource Conservation and Recovery Act (RCRA) regulations. Disposal - Permanently containing hazardous wastes. The most common type of disposal facility is a landfill, where hazardous wastes are disposed of in carefully constructed units designed to protect groundwater and surface water resources. ICE Sites: The Department of Toxic Substances Control (DTSC) regulates the generation, transportation, treatment, storage, and disposal of hazardous wastes. DTSC monitors compliance with state and federal hazardous waste requirements by conducting inspections. DTSC works to ensure compliance with environmental requirements. When warranted, DTSC will take civil or criminal enforcement action against violators of environmental laws. DTSC provides compliance incentives and auditing to encourage facilities to find and disclose violations to the Agency. Violations may also be discovered from tips/complaints received by the Agency from the public. Violations discovered as a result of any of these activities may lead to civil or criminal enforcement.
