ECCC’s Mandate

  • Preserve and enhance the quality of the natural

environment

  • Conserve Canada’s renewable resources
  • Conserve and protect Canada’s water resources
  • Forecast daily weather conditions and warnings
  • Enforce rules relating to boundary waters
  • Coordinate environmental policies and programs for the

federal government

  • Migratory Birds Convention Act
  • Species at Risk Act

Recommendation 1 – Effluent Quality

ECCC Recommends:

  • Chloride concentrations should be monitored in the lake

and the proponent should ensure that chloride concentrations do not violate section 36(3) of the Fisheries Act.

  • The proponent should also ensure that Total Dissolved

Solids concentrations do not violate section 36(3) of the Fisheries Act.

Recommendation 2 – Dike Construction TSS Management and Monitoring

ECCC Recommends:

  • Calculation of the moving 30 day average should not include

baseline data for the first 30 days, i.e. it would be a simple average for this period.

  • Monitoring results for dike construction should be reported in

addition to the Surveillance Network Program data and could be included in the Annual Report as well (as an example, see the Meadowbank Gold Project 2010 Annual Report Appendix A4 Report: 2010 Causeway and Dike Construction Monitoring Report).

  • Real-time turbidity measurements be taken using automated

loggers, to supplement the daily turbidity profiles, including in winter. Most appropriate sites should be determined taking turbidity barrier configuration and bathymetry into account.

Recommendation 3 – Use of Sub Lethal Toxicity Testing

ECCC recommends:

  • Chronic toxicity testing be done on whole effluent from

end-of-pipe in order to eliminate effects on test results from testing in the receiving environment. Tests could include the Ceriodaphnia test, algal test, fish early life stages, and Lemna.

Recommendation 4 – Seepage Quality

ECCC Recommends:

  • Seepage from the Jay Waste Rock Storage Area be

closely monitored for occurrence.

  • If observed, seepage should be characterized for

chemistry and flow volumes (not just during the twice a year seepage survey program).

  • Contingencies should be identified for diverting and

retaining any poor quality flows in order to prevent the seepage from entering Lac du Sauvage.

Recommendation 5 – Aquatic Effects Monitoring Program (AEMP)

ECCC Recommends:

  • An AEMP working group be formed, or a workshop

format meeting be used to discuss and address details

  • f the proposed monitoring program.
  • Monitoring during the operations phase should be linked

to and build comprehensively on the baseline information and construction phase.
