Map

To view facility data on the map, select from among the left-hand menu options.

For example, if you want to know which facilities reported air releases in your state, province, or territory, select the following parameters, then click “Apply”:

  • A specific year
  • Your state/province/territory
  • “All industry sectors”
  • “On-site air emissions”

      * With certain exceptions, Canadian facilities reporting an on-site release of less than one tonne are not required to report the specific medium of the release (e.g., to air, water). Therefore, the NPRI “total onsite release” amount might not equal the sum of the individual on-site release categories.

      ** Quantities of metals reported as transferred off-site for sewage, treatment, or energy recovery are included in the "Off-site Disposal" category, since these metals may be captured and removed from waste and disposed of in landfills, or by other methods. This approach recognizes the physical nature of metals and the fact that they are not likely to be destroyed through treatment.

      The data are taken from the US Toxics Release Inventory, the Canadian National Pollutant Release Inventory (NPRI), and the Mexican Registro de Emisiones y Transferencia de Contaminantes (RETC). Each country has its own list of mandatory pollutants. Reporting thresholds for pollutants, sectors and facilities also vary. For details, see Understanding Taking Stock.

      The national PRTR datasets are constantly evolving, as facilities revise previous submissions to correct reporting errors or make other changes. For this reason, the three countries 'lock' their data sets on a specific date and use the 'locked' data for annual summary reports. Each year, the countries issue revised databases that cover all reporting years. The CEC follows a similar process. For the purposes of this database, the NPRI dataset from December 2018, the TRI Basic Data Plus dataset from April 2019 and the RETC dataset from December 2018 were used. Readers can visit the national PRTR websites to see if any changes to the data have occurred.

      Pollutants:
      • Units of Measurement:
        • Values reported in pounds are converted to kilograms using a conversion factor of 2.205
        • Values reported in tonnes are converted to kilograms using a conversion factor of 1000
      • Certain pollutants, such as metals, are grouped in Taking Stock (e.g.: "lead and/or its compounds"). Therefore, no CAS number is assigned to the group.
      • For NPRI, facilities reporting an on-site release of less than one tonne (with exceptions) are not required to report the specific medium of the release (e.g., to air, water). Therefore, the “total on-site release” amount might not equal the sum of the individual on-site release categories.
      • View the List of Pollutants Reported to the North American PRTRs.
      • Pollutant Types:
        • A = Criteria Air Contaminants
        • D = Developmental/Reproductive Toxins (on California Prop 65 List)
        • G = Greenhouse Gases
        • C = Known or suspected carcinogen
        • M = Metal and metal compounds
        • P = Persistent, Bioaccumulative and Toxic
      • All values are measured in kilograms unless otherwise noted.
        1. Values reported in pounds are converted to kilograms using a conversion factor of 2.205
        2. Values reported in tonnes are converted to kilograms using a conversion factor of 1000
        3. Important: Dioxins and Furans are reported differently in each country. Reported amounts are converted to kilograms in the database, but users should keep in mind these differences and consult the national databases for details.
      • Certain pollutants, such as metals, are grouped (e.g.: "lead and its compounds") – therefore, no specific CAS number is assigned to the group.
      • Certain pollutants are reported under different thresholds (the amount above which the pollutant must be reported) in each country. Standard thresholds for most pollutants are:
        1. Canada NPRI: 10,000 kg
        2. United States TRI: 25,000 lbs (11,340 kg)
        3. Mexico RETC (there are two thresholds): 1,000 kg ("release") or 5,000 ("activity")
      • View the list of common pollutants (pollutants common to at least 2 of the North American PRTRs), which also indicates the reporting thresholds.
        1. For a comprehensive list of all pollutants reported in each country and each year, view the Comprehensive table of reported pollutants.
        2. There are differences in industry sector coverage in each country. For more details, see Understanding Taking Stock.
      • Criteria Air Contaminants and Greenhouse Gases
        1. Criteria Air Contaminants and Greenhouse Gases are only reported in Canada and Mexico
        2. For a comprehensive list of all CACs and GHGs reported in each country and each year, view the Comprehensive table of reported CACs and GHGs .
