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. This data is a geospatial representation of data found at https://www.envirostor.dtsc.ca.gov/public/. This dataset is updated daily.

,The California Environmental Protection Agency (CalEPA) is responsible for identifying disadvantaged communities for purposes of the Cap-and-Trade funding program. After reviewing the updated results from CalEnviroScreen 3.0 and taking into consideration previous comments and input received over the past two years, including workshops held in February 2017, CalEPA is designating the highest scoring 25% of census tracts from CalEnviroScreen 3.0 as disadvantaged communities. Additionally, 22 census tracts that score in the highest 5% of CalEnviroScreen’s Pollution Burden, but do not have an overall CalEnviroScreen score because of unreliable socioeconomic or health data, are also designated as disadvantaged communities.,For more information, including maps and data, see http://www.calepa.ca.gov/envjustice/ghginvest/,For OEHHA’s page on SB535, see: https://oehha.ca.gov/calenviroscreen/sb535,

,CalEnviroScreen is a mapping tool that helps identify California communities that are most affected by many sources of pollution, and where people are often especially vulnerable to pollution’s effects. CalEnviroScreen uses environmental, health, and socioeconomic information to produce scores for every census tract in the state. The scores are mapped so that different communities can be compared. An area with a high score is one that experiences a much higher pollution burden than areas with low scores. CalEnviroScreen ranks communities based on data that are available from state and federal government sources.,

This asset includes the EPA Federal Agency Hazardous Waste Compliance Docket (Docket), which is required by Section 120(c) of the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). The Docket contains information reported to EPA by federal facilities that manage hazardous waste or from which hazardous substances, pollutants or contaminants have been or may be released. The Docket serves three major purposes: 1. To identify all federal facilities that must be evaluated through the site assessment process to determine whether they pose a risk to human health and the environment sufficient to warrant inclusion on the National Priorities List (NPL); 2. To compile and maintain the information submitted to EPA on such facilities under the provisions listed in section 120(c) of CERCLA; and 3. To provide a mechanism to make the information available to the public. The docket includes facilities which have provided information to EPA through documents such as reports under a Federal agency environmental restoration program, regardless of the absence of section 103 reporting. E-Docket is an internal business management tool that will improve the tracking and record keeping of information about facilities that have been identified as potential Docket sites. The functionality of the system is basic record tracking, and it will contain a list of draft proposed facilities which can be sorted based on Agency ownership, region, or status (Draft Proposed, Proposed, Added, or Not Added). The information compiled in the tool is publicly available. The data asset also includes the FFRRO Regional Work Planning Application, which is a tool for the Superfund Federal Facilities Response Program. It collects regional site-specific planning targets for program measures. This data is entered by the regions and used by HQ to estimate and target program accomplishments.

This data provides results from field analyses, from the California Environmental Data Exchange Network (CEDEN). The data set contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Due to file size limitations, the data has been split into individual resources by year. The entire dataset can also be downloaded in bulk using the zip files on this page (in csv format or parquet format), and developers can also use the API associated with each year's dataset to access the data. Example R code using the API to access data across all years can be found [here](https://gist.github.com/daltare/2de1517ad1e315c4b1cad01278de96dd). Users who want to manually download more specific subsets of the data can also use the CEDEN query tool, at: https://ceden.waterboards.ca.gov/AdvancedQueryTool
