        The National Pollutant
       Release Inventory (NPRI)

               CEC PRTR Annual Meeting
                San Diego—Nov. 2006
   The NPRI is a major component of Canada’s broader suite of pollution
information resources. It is complemented by comprehensive air emission
 inventories, the NAPS ambient monitoring network and other programs…

Since its establishment in 1992, the NPRI has grown significantly to
 provide more comprehensive information on pollution in Canada…

    Moreover, the NPRI continues to evolve to address public, government and
    other needs for information related to pollution in Canada; and to improve
                 comparability in the North American context…

•    2006: Removal of mining exemption except for pits and quarries
      –    Addition of 3 PAH species, 6 glycol ethers and 7 mineral spirits
      –   Expansion of NPRI facility definition to include ―portable‖ facilities
•    2004: Harmonized, ‗one-window‘ online reporting through OWNERS
•    2003: Removal of reporting exemptions for oil & gas sector
      –   Addition of 60 ‗speciated‘ volatile organic compounds (VOCs)
•    2002: Addition of Criteria air contaminants (CACs)
      –   Reduced reporting thresholds for arsenic & lead
      –   Removal of reporting exemptions for waste incinerators
•    2000: Reduced reporting threshold for mercury
      –   Addition of 17 polycyclic aromatic hydrocarbon (PAH) species
      –   Addition of dioxins & furans as a single group; and hexachlorobenzene (HCB)
•    1999: Addition of 73 new substances
      –   Required reporting of D-U-N-S number
•    1998: Mandatory reporting of transfers for recycling
      –   Adoption of NAICS for industrial classification
       Planned, future changes include…


• Required reporting of individual dioxin & furan congeners

• Reporting of additional PAH species

• Addition of other substances to the NPRI list as a result of
  categorization of Canada‘s Domestic Substances List (DSL)

• Development of more effective tools to facilitate access, analysis,
  interpretation, use and understanding of NPRI data
While providing more comprehensive information for decision
making, dramatic growth in NPRI reporting over time creates
          challenges for accurate trend analysis…

• Growth in the number of facilities reporting to the NPRI has far
  exceeded actual growth in the Canadian economy (see following
  slide…)

• ―Consistent facilities‖ approaches are required for representative
  long-term trend analysis based on NPRI data

• Taking Stock 2003 includes expanded ―consistent facilities‖
  analysis

• Canada looks forward to the addition of consistent facilities analysis

“In Conclusion…”

   PRTR data is a valuable resource available to the public,
    governments, industry, non-governmental organizations,
    academic researchers and the media.

   But context is required for data analysis and
    presentation to be the most accurate and relevant
    possible

   Canada looks forward to continued collaboration with
    the US, Mexico and CEC Secretariat in further improving
    the quality, comparability, analysis and presentation of
    tri-lateral PRTR data
