Recently Released Data Sets

• Integrated Risk Information System (IRIS) Dataset
  Learn More | Dataset
  EPA's Integrated Risk Information System (IRIS) is a human health assessment program that evaluates risk information on effects that may result from exposure to environmental contaminants. Through the IRIS Program, EPA provides the highest quality science-based human health assessments to support the Agency’s regulatory activities. The IRIS database contains information for more than 540 chemical substances containing information on human health effects that may result from exposure to various substances in the environment.
• Civil Penalty Policies
  Learn More | Data.gov summary
  Tool contains EPA's policy documents relating to violations or noncompliance with the environmental statutes and regulations, dating back to 1984.
• Consent Decrees
  Learn More | Data.gov summary
  EPA's Office of Enforcement and Compliance Assurance (OECA) cases and settlements web page contains links to selected settlements resolving civil enforcement cases and, in some cases, complaints filed initiating civil judicial and administrative enforcement actions. Typically, the links are to settlements about which we have issued a press release. This is not a complete repository of all enforcement actions taken by or on behalf of EPA. Rather, it represents a subset of enforcement cases, taken civil judicially or administratively, which may be of national interest. Most of the settlements are civil judicial consent decrees resolving alleged violations of environmental laws (e.g., the Clean Air Act, the Clean Water Act). In some instances, the website includes significant enforcement actions resolved by the Environmental Appeals Board (EAB).
• Toxics Release Inventory Data, 1987-2008
  Learn More | Data.gov summary
  The Toxics Release Inventory (TRI) Program compiles the TRI data on toxic chemical releases and waste management activities reported annually by certain industries as well as federal facilities. The goal of the Toxics Release Inventory program is to provide communities with information about toxic chemical releases and waste management activities and to support informed decision making at all levels by industry, government, non-governmental organizations, and the public. The new TRI data sets that are being made available via Data.gov for the first time improve upon the previously available TRI data sets in several key ways. More reporting years are covered (1987-2008 rather than 2005-2008), the download format has changed (.CSV rather than .EXE), and the data is more current (download links now point to the "Current Data" for TRI, which is updated on a yearly basis to reflect facility revisions and withdrawals, rather the "National Analysis" data, which is a static data set).
• Toxic Chemical Substances Inventory
  Learn More | Data.gov summary | Extraction Tool
  This dataset consists of the non confidential identities of chemical substances submitted under the Toxic Substances Control Act (TSCA).  TSCA was enacted to ensure that chemicals manufactured, imported, processed, or distributed in commerce, or used or disposed of in the United States do not pose any unreasonable risks to human health or the environment.  EPA adds chemical substances to the TSCA Inventory following EPA's receipt of a Notice of Commencement (NOC) signaling the manufacturer's intent to produce a chemical substance that EPA has previously reviewed and approved. Since EPA published the final TSCA Inventory Reporting Rule on December 23, 1977, the TSCA Inventory has grown to include the identities of over 83,000 chemical substances.
• Chesapeake Bay Program Water Quality Database
  Learn More | Data.gov summary | Download data
  The Chesapeake Bay is a national treasure and the subject of President Obama's May 12, 2009 Executive Order 13508. These water quality data can be used by interested members of the public to understand and visualize the environmental condition of the Bay. This water quality monitoring dataset was not previously available online in a downloadable, open format.
• ToxCast Phase I:
  Learn More | Data.gov summary | Download data
  Thousands of chemicals found in the environment lack data about their potential human health and environmental effects. Chemical toxicity testing is being transformed by advances in biology and computer modeling and concerns over animal use. EPA's ToxCast program has begun to use new, “high-throughput” techniques to screen and prioritize chemicals for potential human toxicity. This dataset represents the first outputs from ToxCast, for 309 chemicals. This dataset was never available online before in a downloadable, open format. The data can be used by science-oriented members of the public to examine the properties of the chemicals for possible activities of interest.
• Toxics Release Inventory Chemical Hazard Information Profile (TRI-CHIP) Dataset:
  Learn More | Data.gov summary | Download data
  The Toxics Release Inventory (TRI) Chemical Hazard Information Profiles (TRI-CHIP) dataset contains hazard information about the chemicals reported in TRI. Members of the public can use the information in conjunction with chemical release information from TRI to better understand toxic chemical-related activities in their communities and conduct their own hazard analyses. This dataset was never available online before in a downloadable, open format.
• New Mapping Tool for Enforcement
  Cases:
  Learn More | Data.gov summary | Download data
  The new mapping tool shows facilities in the United States where the EPA concluded formal environmental enforcement actions between October 1, 2008 and September 30, 2009 (FY2009). These maps do not show environmental enforcement actions taken by other federal agencies or state or local environmental agencies. The purpose of the data set is to visually display the majority of formal environmental enforcement actions that EPA concluded in FY2009. Members of the public can use the data to do their own geographic analyses based on their particular interests. This dataset was never available online before in a downloadable, open format.
