Appendix 1 – Comparison of 2006-2008 and 2009 NPRI reporting requirements for tailings and waste rock
DescriptionDetails of applicability for 2006-2008 NPRI reporting of tailings and waste rockDetails of applicability for 2009 NPRI reporting of tailings and waste rock
Legislative requirementsPublished on December 5, 2009 in the Canada Gazette Part I Notice with respect to tailings and waste rock reporting under the National Pollutant Release Inventory for 2006 to 2008Published on December 5, 2009 in the Canada Gazette Part I Notice with respect to substances in the National Pollutant Release Inventory for 2009
What is the deadline date to comply with this notice?June 1, 2010June 1, 2010
What substances are required to be reported for disposals in tailings and waste rock management areas?

Only substances from Parts 1 and 2 are included in the 2006-2008 notice. 

A substance report, including information on disposals to tailings and waste rock management areas, is required for each of the above NPRI substances for which the applicable mass reporting threshold is met or exceeded. 

For 2009, NPRI substances in Parts 1, 2, and 3 are applicable for reporting on tailings and waste rock.

A substance report, including information on disposals to tailings and waste rock management areas, is required for each of the above NPRI substances for which the applicable mass reporting threshold is met or exceeded.

Which sectors are required to report NPRI substances in tailings and waste rock?The 2006-2008 notice is limited to facilities from the bitumen, coal, diamonds, metals, and potash sectors that generated or disposed of tailings or waste rock during at least one of those years.For 2009 reporting, facilities from other industry sectors beyond mining are subject to the tailings and waste rock requirements.  As such, if a facility from any sector disposes of waste rock or tailings, they would need to report on it (provided they meet thresholds and have information on NPRI substances in the waste rock or tailings, and subject to the exclusions for inert materials).
What facilities are subject to the notice?

Facilities are subject to the 2006-2008 notice if, during one or more of the 2006-2008 calendar years:

  • employees at the facility worked 20 000 hours or more; and
  • the facility generated or disposed of tailings or waste rock as a result of the extraction or recovery of bitumen, coal, diamonds, metals or potash, or the extraction or beneficiation of metallic ore or ore concentrate.
The general NPRI requirements apply for the 2009 notice – this would include facilities beyond the mining sector.
Who is required to report?The owner or operator of the facility as of December 31, 2009 is required to report for the 2006-2008 years.   If the facility closed during that period, the last owner or operator of the facility is required to report.The owner or operator of the facility as of December 31, 2009 is required to report for the 2009 NPRI.
Are there any exclusions specific to tailings and waste rock that should be considered in the determination of the mass reporting thresholds?

NPRI substances contained in the following materials should be excluded from the determination of the mass reporting threshold:

  1. Unconsolidated overburden
  2. Component of tailings that are inert, inorganic and have not been crushed or otherwise altered.
  3. Inert waste rock – refer to Guide for more details about what is inert and what is not

NPRI substances contained in the following materials should be excluded from the determination of the mass reporting threshold:

  1. Unconsolidated overburden
  2. Component of tailings that are inert, inorganic and have not been crushed or otherwise altered.
  3. Inert waste rock – refer to Guide for more details about what is inert and what is not
Once a facility has met the reporting threshold for reporting mine wastes, what information is required to be reported to the NPRI?

The general information requirements for the 2006-2008 notice include the following:

  • information is based on information the person has reasonable access to;
  • there is a requirement to use monitoring data, if required under other legislation;
  • the person is not required to report quantities if they are excluded from threshold calculations (i.e. overburden, etc.);
  • certification of the report is required; and
  • quantities would be reported in tonnes or kg as normal for that substance.

The owner or operator of a facility subject to the notice, and which met the criteria for one or more listed substances during one or more of the reporting years, would be required to submit a report by June 1, 2010.

Please consult this Guide and the 2006-2008 notice for a complete listing of information that is required to be submitted to Environment and Climate Change Canada by June 1, 2010.

The general information requirements for the 2009 notice include the following:

  • information is based on information the person has reasonable access to;
  • there is a requirement to use monitoring data, if required under other legislation;
  • the person is not required to report quantities if they are excluded from threshold calculations (i.e. overburden, etc.);
  • certification of the report is required; and
  • quantities would be reported in tonnes or kg as normal for that substance.

The owner or operator of a facility subject to the notice, and which met the criteria for one or more listed substances during one or more of the reporting years, would be required to submit a report by June 1, 2010.

Please consult this Guide and the 2009 notice for a complete listing of information that is required to be submitted to Environment and Climate Change Canada by June 1, 2010.
