National Pollutant Release Inventory (NPRI) On-Line Data Search Help

The NPRI On-line data search engine can be used to find information about pollutant releases, disposals, and recycling for reporting facilities across Canada. This database can be searched in many different ways, described in further detail below. It is not recommended to search the database without entering facility, substance, and/or location information, as it will return the complete database for the specific reporting year. The complete databases for each reporting year are downloadable from the NPRI website.


2 DIGIT CANADIAN SIC CODE

The SIC code is the Standard Industrial Classification Code. The 2 digit code is a broad grouping of similar industries. Selecting a code from the drop-down list will limit the search to just that industrial sector, otherwise select ALL.


4 DIGIT CANADIAN SIC CODE

The SIC code is the Standard Industrial Classification Code. The 4 digit code is a detailed grouping of similar industries. Selecting a code from the drop-down list will limit the search to just that industrial sector, otherwise select ALL.


AMERICAN SIC CODE

The American SIC code is the American Standard Industrial Classification Code. Selecting a code from the drop-down list will limit the search to just that industrial sector, otherwise select ALL.


CAS NO.

Chemical Abstracts Service Number. This is a standard identifier for all chemical substances. Picking a single CAS Number from the drop-down list will limit the search to only those facilities reporting for that substance, otherwise select ALL. When doing a search for a substance, the releases, disposals and recycling totals for each facility will also be displayed in the results screen. Details for each facility can be accessed by selecting the appropriate NPRI ID in the first column or the facility name in the second column of the table.


COMMUNITY (25 km RADIUS REPORTING)

Using this search criteria will return any facilities located within a 25 km radius of the selected community. Step 1 - select a province for which you want information.  Click the "Refresh Community List" button to access a drop-down list of communities in that province. Step 2 - Select a community from the drop-down list for which you want information.


DISPOSALS

Disposal means the final disposal of a substance to landfill, land application, or underground injection either at the facility or at an off-site location. Disposal also includes treatment at an off-site location prior to final disposal.

Waste materials, such as sludge, are often a mixture of many compounds associated with water and other inert material. As a result, the total quantity reported to the NPRI may be smaller than that reported in other emission inventories.

Off-site treatment does not necessarily constitute an environmental release because the pollutant may be altered chemically or physically, and may not be ultimately released in its original form. Disposals may be reported as follows:

  • On-site disposal - landfill, land application, underground injection; tailings management, waste rock management
  • Off-site disposal - landfill, land application, underground injection, storage, tailings management waste rock management
  • Off-site transfers for treatment prior to final disposal -
    • physical treatment such as encapsulation and vitrification;
    • chemical treatment such as precipitation, stabilization and neutralization;
    • biological treatment such as biooxidation;
    • incineration or thermal treatment where energy is not recovered; and municipal sewage treatment plant (MSTP).

Landfills are sites in which wastes containing NPRI pollutants are buried. Most landfills found in Canada are provincially approved waste-disposal sites. Some landfills are classified as hazardous waste only. Regardless of classification, all landfills are required to have appropriate permits and be specifically designed under strict guidelines for use as final disposal sites for waste. In most cases, permitted landfills are managed to minimize the release of pollutants to the natural soil.

Underground injection is a method of waste disposal. Subject to provincial regulation, wastes are injected into known geological formations at great depths.


FACILITY NAME

You can search by a specific facility name by entering all or part of the name into the "Facility Name" field. Entering only part of a facility name may return more results. For example, if you did a search on facility name "apple", the result could contain such results as "Apple Co.", "Better Apple Industries" and "Crabapple Inc".

If you are searching for a name that may contain diacriticals such as é, è, ç or Î, substitute the % sign for the letter involved. For example Montr%al will return both Montreal and Montréal. Alternatively, searching for Montr will also capture both spellings.


GREENHOUSE GAS EMISSIONS

The mandatory reporting of GHG emissions by major emitters was introduced in March 2004 by the Government of Canada. The GHG emissions reporting program specifically targets facilities in Canada that emit the equivalent of 100,000 tonnes or more of Greenhouse Gases (in CO2 equivalent units) annually. It is important to note that the emissions information collected and published by this program represent only a portion of industrial emitters in Canada. The totals published by the GHG Emissions Reporting program represent a subset of the larger picture provided by the National Inventory.


MAJOR URBAN CENTRE (POPULATION >10,000)

The database can be searched using a drop-down list of urban centres with a population of at least 10,000. This method will return all facilities located within the boundaries of the major urban centre.


NAICS CODE

The NAICS code is the North American Industrial Classification code. The 4 digit code is a broad grouping of similar industries. Selecting a code from the drop-down list will limit the search to just that industrial sector, otherwise select ALL.

NOTE: NAICS codes have been collected since 1998. The NPRI uses NAICS 1997.


NPRI ID

You can search for specific facilities by ID number. Specifying a unique ID number will limit the search to a single facility and is the fastest way to retrieve NPRI data for a specific facility.


O. REG. 127/01 SUBSTANCES

Ontario Regulation 127/01: Airborne Contaminant Discharge Monitoring and Reporting requires Ontario-based facilities that emit certain quantities of substances to report their emissions. Further details about the regulation are available at www.ene.gov.on.ca/envision/monitoring/monitoring.htm.

Commencing with the 2005 reporting year, emissions data under the regulation is available on the NPRI website. Emissions data for years prior to 2005 is available on the MOE website at www.ene.gov.on.ca/envision/monitoring/ohr.htm


OFF-SITE TRANSFERS FOR RECYCLING

Recycling refers to activities that keep a material or a component of the material from becoming a waste destined for disposal. Recyclable materials may be cleaned, regenerated or reprocessed to their original specifications and reused for their original purpose. They may also be used for an entirely different purpose without any pre-treatment or modification. Components may be recovered or reclaimed from the recyclable material or the material may be used as a fuel for energy recovery. The recyclable material may be used in the manufacture of another product. For the purposes of the NPRI, recycling also includes substances sent back to the manufacturer or supplier for reprocessing, repackaging, resale or for credit or payment.


ON-SITE RELEASES

An on-site release is a discharge of a pollutant to the environment within the boundaries of the reporting facility. This includes emissions to air, discharges to surface waters, and on-site releases to land. Releases are subdivided as follows:

  • Air-stacks and other point sources, storage and handling, fugitive emissions, spills or other non-point sources. For O. Reg. 127/01, particulate matter species include releases from road dust only;
  • Surface water - discharges, spills and leaks
  • Land - spills, leaks and other releases

Surface water releases do not include discharges to municipal wastewater treatment plants. These are reported under off-site transfers for treatment prior to final disposal.

A leak differs from a spill in terms of the time required for an event. Spills normally occur over a period of hours to days, whereas leaks occur over periods of days to months.


POLLUTION PREVENTION ACTIVITIES

Pollution prevention (P2) is defined as "the use of processes, practices, materials, products, substances or energy that avoid or minimize the creation of pollutants and waste, and reduce the overall risk to the environment or human health" (CEPA 1999). P2 seeks to eliminate the causes of pollution rather than managing it after it has been created. It encourages the kinds of changes that are likely to lead to lower production costs, increased efficiencies and more effective protection of the environment.

This section identifies P2 activities implemented by the facility for the reporting year, and any comments on P2 activities provided by the facility.


POSTAL CODE

Enter one to three digits of the postal code. The search will be limited to facilities with addresses in that area.


PROVINCE/TERRITORY

Selecting a specific province or territory will limit the search to facilities in that province or territory, otherwise select ALL.


REPORTING YEAR

You can see reports only for a specific year. The default is the most recent year for which data is available. Select a year using the drop-down list.


SUBSTANCE NAME

Selecting a specific substance from the drop-down list will limit the search to only those facilities reporting for that substance, otherwise select ALL. When doing a search for a substance, the releases, disposals and recycling totals for each facility will also be displayed in the results screen. Details for each facility can be accessed by selecting the appropriate NPRI ID in the first column or the facility name in the second column of the table.


SUBSTANCE REPORT (CRITERIA AIR CONTAMINANTS)

The CAC Report is a list of Criteria Air Contaminants (CAC) reported by a facility for a given year. The report provides information on releases to air from the facility for each CAC. Additional information on a specific CAC can be viewed by clicking on the substance name in the first column or the CAS Number in the second column of the table.


SUBSTANCE REPORT (EXCLUDING CRITERIA AIR CONTAMINANTS)

The Substance Report is a list of all substances reported by a facility for a given year, except for Criteria Air Contaminants (CAC). CAC information is provided in a separate report. The substance report provides release, disposal, and recycling information for each substance. Additional information on a specific substance can be viewed by clicking on the substance name in the first column or the CAS Number in the second column of the table.
