SLIDE 2 Presentation Overview
- Conceptual Management Plans
- Waste Management and Incineration Management Plans
- Waste Management: Petroleum Hydrocarbons (Water and Soil)
- Spill Contingency Plan
- Information Request #6 - ETF Performance Evaluation
- Closing
SLIDE 3 Conceptual Management Plans
- The proponent has provided conceptual
management/mitigation plans because the mine design has not been finalized.
- Management plans are key to minimizing
impacts to the environment.
SLIDE 4
Conceptual Management Plans - ENR Recommendations
1) The proponent submit for approval all management plans on a milestone basis. Each plan should be submitted prior to the activity, construction and operation
SLIDE 5
Conceptual Management Plans - ENR Recommendations
2) The Waste Management and Incineration Management Plan (WMIP) and the Spill Contingency Plan (SCP) be updated within 30 days after the issuance of a LUP/WL. In addition, as the mine design is finalized, any major changes (i.e. additional fuel storage, fundamental process changes etc.) to the WMIP and SCP must be submitted 60 days prior to the alteration for review and approval by the Board.
SLIDE 6 Conceptual Management Plans - ENR Recommendations
3) For all other management plans, the submission should correspond to major milestone events (discharge of mine effluent, explosive magazine construction etc.) as the mine design is finalized. All management plans be submitted a minimum
- f 60 days prior to the activity or after
substantial alteration, as is consistent with other mine sites regulated by the WLWB.
SLIDE 7 Waste Management and Incineration Management Plans
- ENR met with proponent on January 21, 2014 to
further discuss outstanding issued identified during the technical sessions held by the WLWB.
- The proponent committed to looking into alternative
- ptions for waste management, however no written
commitments have been provided at the time of this intervention.
- It is anticipated that updates will be incorporated into
the final WMIP.
SLIDE 8
Waste Management and Incineration Management Plans - ENR Recommendations 1) The proponent provide an updated management plan that addresses the concerns raised in ENRs written intervention and throughout the process.
SLIDE 9
Waste Management and Incineration Management Plans - ENR Recommendations 2) The WLWB include a testing requirement for waste oil and residual ash, including analytical criteria, in the WL for the management of potentially hazardous waste.
SLIDE 10 Waste Management: Petroleum Hydrocarbons
(Water and Soil)
- ENR met with proponent on January 21, 2014 to
further discuss outstanding issued identified during the technical sessions held by the WLWB. ENR has concerns with respect to the petroleum hydrocarbon management, in water and soil, at the NICO site.
- No commitments have been provided in a
finalized plan, though it is anticipated that updates will be incorporated at a later date.
SLIDE 11 Waste Management: Petroleum Hydrocarbons
(Water and Soil)
- ENR notes that the treatment of petroleum
hydrocarbon contaminated water may be necessary once underground sumps are established for the NICO Site.
- Because all water will be directed to a central
location (surge pond), the current Effluent Treatment Facility (ETF) may not be able to remove hydrocarbon contaminants from water.
SLIDE 12
Waste Management: Petroleum Hydrocarbons – ENR Recommendations
1) The proponent provide a Landfarm Management Plan (LMP) a minimum of 60 days prior to its construction. 2) LMP should include engineered drawings and details of its design, operation and waste segregation methods.
SLIDE 13 Waste Management: Petroleum Hydrocarbons – ENR Recommendations
2) Landfarm design should specify details on a soil cell and a separate cell for hydrocarbon-impacted snow/water. Design must include a method for water treatment
- f petroleum hydrocarbon-impacted water.
SLIDE 14 Waste Management: Petroleum Hydrocarbons – ENR Recommendations
3) The WLWB should include both soil and water treatment criteria for petroleum hydrocarbons in the WL.
- Potential Licence Criteria for soil, if it is to be used for
cover at closure, should be based on the GNWT Contaminated Site Remediation Guidelines agricultural criteria and/or Canadian Council of the Ministers of the Environment Canada-Wide Standard for Petroleum Hydrocarbons agricultural/wildland criteria be adopted for the remedial targets.
SLIDE 15 Waste Management: Petroleum Hydrocarbons – ENR Recommendations
- Potential licence criteria of hydrocarbon-
impacted water could be based on the Alberta Tier 1 Soil and Groundwater Remediation Guidelines for benzene, toluene, ethyl benzene and xylene and fraction 1 and 2 petroleum hydrocarbons (PHC).
SLIDE 16 Waste Management: Petroleum Hydrocarbons – ENR Recommendations
5) The proponent should provide an updated plan that includes the treatment of PHC impacted water. Specifically the proponent should indicate if the ETF will be designed with the ability to treat hydrocarbon- impacted water from the surge pond and landfarm. Alternatively provide secondary options for treatment
- r a contingency for complete removal of impacted
water from site in its waste management plan.
SLIDE 17 Spill Contingency Plan
- ENR met with proponent on January 21, 2014 to
further discuss outstanding issued identified during the technical sessions held by the WLWB.
- The proponent has committed to addressing the
deficiencies in the SCP, however no written commitments have been provided at the time of this intervention.
SLIDE 18
Spill Contingency Plan – ENR Recommendation
1) The proponent submit for Board approval an updated SCP within 30 days of the issuance of a LUP/WL. Additionally, if there are significant alterations to the SCP that it be re-submitted to the Board a minimum of 60 days prior to the alteration for approval.
SLIDE 19 Information Request #6 ETF Performance Evaluation - Proponent’s Conclusion
- ENR commends the proponent for agreeing to conduct
bench scale study on simulated effluent prior to the end of construction and prior to discharge. ENR notes that bench scale testing may affect the calculations required for the Effluent Quality Criteria (EQC) and may alter the WL criteria.
SLIDE 20 ENR Review
- Bench scale studies are imperative for the
protection of down-stream aquatic ecosystems and for establishment the EQCs.
- This information is required to develop the
maximum and average daily discharge limits and is critical prior to discharge from site.
