Are There NPRI Changes in The Making?

Reviewing The National Pollutant Release Inventory (NPRI) list has become increasingly important for many Ontario companies as they prepare their Toxic Substance Reduction Plans (TSRP).  As you know, your TSRP is based on your (prior year) reportable NPRI toxic substances.

If Environment Canada’s proposals are approved, the NPRI list may have some changes in the near future that may affect your future environmental reporting.

Here is a brief overview of some of the potential NPRI changes:

Proposed Reporting Threshold Changes

  • Acrylonitrile:  From 10 tonnes to 1 tonne/reporting year.
  • Particulate Matter:  If the reporting threshold for any one of the three PM fractions (total PM, PM 10 or PM 2.5) is met, then all three fractions would have to be reported.
  • Toluene Diisocyanates (2,6-toluene diisocyanate, 2,4-toluene diisocycanate and mixtures of 2,6-toluene diisocyanate and 2,4-toluene diisocycanate):  from 10 tonnes to 100 kg/reporting year and concentration threshold from 1% to .01% by weight.

Proposed Additions

  • Part 1 Additions
    • 2,2-bis (Bromomethyl) – 1,3 propanediol
    • Glycidol
    • Methyleugenol
    • Nitromethane
    • Phenolphthalein
    • Tetrafluoroethylene
  • Part 2 Additions
    • 1,6-Dinitropyrene
    • 1,8-Dinitropyrene
    • 6-Nitrochrysene
    • 4-Nitropyrene

Finally, Environment Canada is considering a change in reporting requirement for chemicals related to the oil and gas sector, and a proposal to add Naphthenic Acids (associated with oil sands).

For Ontario companies, remember the deadline for Phase II TSRP reporting is December 31, 2013.   For more information about the TSRP, see our Environmental Minute.  If you have questions about preparing your TSRP, contact Andrew Tymec (Licensed Toxic Substance Reduction Planner) at 519-979-7300.
