Download Toxic Release Inventory (TRI) 2007 Google Earth Maps

We are updating the KMZ files to include links to RTK Net's very informative and complete TRI facility reports. As we update them, we will mark each map below with an "*."

EPA released the 2007 Toxic Release Inventory (TRI) on March 19, 2009. We worked over the weekend with the data and have all of the states in Google Earth KMZ format for you to download and/or view with Google Earth. Still a few territories to go.

Using the TRI data, especially in map form, is a first and important step towards creating community maps so that you can locate the toxic risks you and your loved ones are exposed to where you work, play and go to school. Scroll down to view or download the maps.

The TRI maps are the first in our series of Right-to-Know pollution maps. The balance include maps of superfund sites, hazardous waste facilities, risk management plan facilities, permit compliance system (water polluting) facilities and AIRS facilities. You can learn more about these below.

"The Toxic Release Inventory program arms communities with powerful information," said Laura Yoshii, acting EPA administrator for the Pacific Southwest region. "The inventory is a tremendous tool to help protect public health and the environment. Safe communities depend on well-informed citizens."

"This information underscores the need for fundamental transparency and provides a powerful tool for protecting public health and the environment," said EPA Administrator Lisa P. Jackson. "Serving the public's right to know is the crucial first step in reducing toxic chemicals in the places where we live, work, and raise children."

"I'm also pleased," Jackson added, "that Congress under the leadership of Senator Lautenberg took action to restore the rigorous reporting standards of this vital program."

TRI is the most comprehensive inventory of information about chemicals released into the environment reported annually by certain industries and federal facilities. These facilities are permitted under strict federal regulations and required to install and maintain pollution controls. On a national level, over 21,000 facilities reported on approximately 650 chemicals for calendar year 2007. TRI allows the public to see which facilities are increasing and decreasing their output of toxic chemicals and compounds, so that stakeholders are well informed about chemicals released into their communities, and industries can gauge their progress in reducing pollution. Thanks to improvements in EPA's system, the vast majority of facilities now report data electronically and detailed information about specific facilities is more readily accessible to the public.

Click a state to open in Google Earth or save to your computer. Feel free to share these with anyone that you like. Note that Safari seems to have a problem hooking up with Google Earth, especially on Macs so best to use Firefox or Internet Explorer. Those marked with "*" have been updated with links to RTK Net.

Note that each state has several to quite a few facilities that did not report their longitude and latitude though they are required to do so by law. These, of course, have not been mapped. Each KMZ file has a link to a page with Excel spreadsheets of these unmapped facilities that you may download.


Here are some ideas for using the TRI data and maps with your GIS program or with Arcexplorer, the free GIS, and our Learn2Map tutorial:

  • Find the largest polluters in your neighborhood and ask them what steps they are taking to reduce their pollution.
  • Do environmental justice research.
  • Publish a toxic atlas of your neighborhood, county or state.
  • Do relocation investigations.
  • Do local facility audits.
  • As a catalyst for forming a local toxic watch group.
  • Distribute printed toxic maps at local events.
  • Use as an aid in landuse planning.
  • Identify potential security-related vulnerabilities.
  • Do habitat and ecological assessment and planning.
  • Assess potential health risks.
  • Study the relationship between health effects and releases.
  • Track offsite transfers of toxics.
  • Do industrial ecology research -- waste from one facility may be "raw" material for another.
  • Discover inaccuracies in reporting and/or location.

Data Source and Geographical Locations

We derived the geographical locations of these facilities using the longitude and latitude that are included in this public data release of the TRI data. The EPA public release also includes such information as amount and name of chemical released, amount of chemical stored on site and other useful information.

Pollution Map Series

Risk Management Plan (RMP)
Under the authority of section 112(r) of the Clean Air Act, the Chemical Accident Prevention Provisions require facilities that produce, handle, process, distribute, or store certain chemicals to develop a Risk Management Program, prepare a Risk Management Plan (RMP), and submit the RMP to EPA. Covered facilities were initially required to comply with the rule in 1999, and the rule has been amended on several occassions since then, most recently in 2004.

Water Pollution (PCS)
The EPA PCS is a national computerized management information system that automates entry, updating, and retrieval of National Pollutant Discharge Elimination System (NPDES) data and tracks permit issuance, permit limits and monitoring data, and other data pertaining to facilities regulated under NPDES. The NPDES permit program regulates direct discharges from municipal and industrial wastewater treatment facilities that discharge into the navigable waters of the United States. Wastewater treatment facilities (also called "point sources") are issued NPDES permits regulating their discharge. Reports for those facilities identified by EPA as "Major" include the names and amounts of chemicals and other substances that are discharged.

Toxic Release Inventory (TRI)
The TRI System (TRIS) contains data submitted to EPA by regulated facilities concerning chemicals and chemical categories listed by the Agency under Section 313 of the Emergency Planning and Community Right-to-Know Act. Data contained in the system include chemicals present, amount of on-site use, releases and off-site transfers (including Publicly-Owned Treatment Works, POTWs), on-site treatment, and minimization/prevention actions. TRIS contains information about releases and transfers of more than 600 toxic chemicals and compounds to the environment. We have included data for TRI facilities that reported their 1997 releases and transfers. Further data and information about the facility and chemicals released and transferred are provided through links to RTK Net.

Superfund Sites NPL
Information on Superfund sites was obtained from the Comprehensive Environmental Response, Compensation and Liability Information System (CERCLIS), which is the official repository for site and non-site specific Superfund data in support of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA, or Superfund). Sites are placed on the National Priorities List (NPL) by EPA if they have uncontrolled releases of hazardous substances that are priorities for long-term remediation and response.

Hazardous Waste Facilities
Information contained in the Hazardous Waste information is taken from the EPA Biennial Reporting System (BRS). It contains information on facilities that treat, store, or dispose (TSD) of RCRA hazardous wastes or are classified as Large Quantity Generators (LQGs) under RCRA. A RCRA hazardous waste is a waste that is both (a) described by one or more federal RCRA waste codes, and (b) is not exempted from RCRA regulations. RCRA classifies as LQG a facility that either (a) generated 1,000 kg or more of RCRA hazardous waste in a single month; (b) generated in a single month or accumulated at any time 1 kg of RCRA acute hazardous waste; or (c) generated or accumulated at any time more than 100 kg of spill clean up material contaminated with a RCRA acute hazardous waste. Reports for those facilities identified by EPA as "Waste Managers" list amount and type of disposal.

AIRS Facilities
EPA’s Office of Air and Radiation stores information on air quality, point source emissions, and area/mobile source data required by federal regulation from the 50 states in its Aerometric Information Retrieval System (AIRS). States are required by the Code of Federal Regulations (CFR) to report to EPA annual emissions estimates for point sources emitting greater than or equal to 100 tons per year of volatile organic compounds (VOCs), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter less than 10 microns in size (PM-10); 1000 tons per year of carbon monoxide (CO); or 5 tons per year of lead (Pb). The Clean Air Act Amendments also require states to report emissions data for point sources in areas where air pollution exceeds Federal standards (nonattainment areas).

Superfund Sites "No Further Action"
There are approximately 24,000 sites that have been included in CERCLIS in the past, but for which EPA requires no further action under the Federal Superfund program.

Superfund Sites NOT on NPL
These are Superfund sites where there is ongoing Federal interest or potential Federal activity, but where the hazard posed is not sufficiently significant or time-critical for the site to be placed on the NPL.
