About myRTK

myRTK is an EPA website designed for mobile devices. For any address, the map displays nearby facilities regulated under federal environmental laws (see Explanations for more detail). Facility reports provide summaries of chemical/pollutant releases, chemical effects, and compliance history from numerous data systems.

Map Legend

blue icon Facilities that reported to the Toxics Release Inventory (TRI) for 2018. TRI reporters are typically large users or manufacturers of chemicals. Facilities must report to TRI if their use of any of the 650+ listed toxic chemicals is higher than the TRI thresholds and they have 10 or more employees.

gray icon Facilities that did not report to TRI but have permits or requirements for the Air, Water or Hazardous Waste programs and are expected to produce, release, or manage TRI-reportable chemicals. These facilities include:

Data Update Information
This version of myRTK is based on data from four sources:

Facility Universe

myRTK displays facilities that report to TRI or other facilities that have permits or requirements for the Air, Water or Hazardous Waste programs and are expected to produce, release, or manage TRI-reportable chemicals. Approximately 61,487 facilities comprise the myRTK universe and meet one or more of these criteria.


Releases in this version of myRTK include only TRI-reportable chemicals.

There are many other pollutants that have significant health and ecosystem effects and which are regulated under federal environmental laws. For example, combustion byproducts, such as, sulfur oxides, nitrogen oxides, particulate matter, and carbon monoxide are the focus of CAA permitting and controls. In addition, EPA is proposing regulations to gather information on air emissions of greenhouse gases, such as carbon dioxide and methane.

At present, estimates of these emissions at the facility level are not included in myRTK. Water pollutants of concern but not included in myRTK include: pollutants that stimulate biological microorganisms and reduce the amount of oxygen in the water for fish; suspended solids; and extreme temperatures and pH. All of these water pollutants interfere with healthy aquatic ecosystems.

Both solid wastes and hazardous wastes regulated under RCRA may pose limited risks if properly managed, but, if released, as in a spill, have the potential for causing harm to human health and the environment.

Health Effects

The check marks on the facility report indicate if 1) EPA has compiled suitable health effects information for this chemical and 2) the assessment indicates if the chemical might cause cancer and if the chemical has any of 17 other health effects. This version of myRTK is limited to human health effects.

The carcinogenicity classifications are taken from the US Occupational Safety and Health Administration (OSHA). The assessments for Other Health Effects are taken from EPA's TRI Chemical Hazard Information Profiles (TRI-CHIP), a database compilation of health effects from numerous other sources.

It should be noted that if neither health effect end point is checked on the facility report, toxicity information is not available.


The three principal U.S. environmental statutes are included in this version of myRTK: Clean Air Act (CAA), which controls pollutant emissions to the air; the Clean Water Act (CWA), which controls discharges to the nation's waterways; and the Resource Conservation and Recovery Act (RCRA), which requires proper handling of solid and hazardous wastes.

The three-year compliance summary displays the most serious non-compliance across the most recent twelve quarters of data for CAA, CWA and RCRA requirements at the facility. For example, if the facility is deemed to have been in significant non-compliance for any portion of the three-month quarter under any program, that quarter will be displayed in red (significant non-compliance).

The "More Compliance Data" link in the facility report Compliance section retrieves a detailed compliance records from EPA's Enforcement and Compliance History Online (ECHO) website, where records may be more current than the information on myRTK.
