The predicted environmental impacts of this project and the proposed mitigations are contained in the attached Project Proposal Report (PPR). After the application of the mitigation measures proposed in the PPR, the potential residual effects of the project are
anticipated: to be short-term in nature with the exception of potential effects to groundwater associated with the
NHW facility; to occur occasionally throughout the Project; and to be limited to areas directly disturbed by the Project (footprint) and areas within 500 m of the footprint because the Project will use areas of existing disturbance as much as possible to mitigate potential residual effects. The effects to all value components (VCs) are evaluated as low magnitude and will not threaten the sustainability of VCs.
Waste Type |
Quantity Generated |
Treatement Method |
Disposal Method |
Non-Combustible wastes |
60 m3 (vol. after crushing) |
The NHW will undergo long term monitoring (LTM) post remediation |
The non-hazardous waste (empty barrels) will be emptied, cleaned, crushed, and disposed of in a non-hazardous waste (NHW) facility constructed at the Site |
Non-Combustible wastes |
6815 m3 (in waste disposal areas (WDAs)) |
The NHW and any WDA left in place will undergo long term monitoring (LTM) post remediation |
The WDAs will be classified in accordance with the Abandoned Military Site Remediation Protocol (AMSRP) (INAC, 2008) to designate each as a Class A, B or C and determine the appropriate remedial action prior to the remedial program. Any excavated hazardous materials shall be segregated and disposed off-site, while excavated NHW will be disposed of in the on-site NHW facility. |
Non-Combustible wastes |
80 m3 (may contain some combustible wood) |
The NHW will undergo long term monitoring (LTM) post remediation |
The Infrastructure (Tank Farm and Wooden Shed) will be dismantled, incinerated or compacted, and non-combustibles will be disposed of in the on-site NWH facility. Tank farm will require an assessment priorto remedial program to determine if/what contents are present and if the paint on tanks is amended paint. |
Non-Combustible wastes |
3430 m3 |
The NHW will undergo long term monitoring (LTM) post remediation |
The surface solid debris will be collected, segregated, shredded, compacted and disposed of in the on-site NWH facility. Combustibles such as inert wooden materials will be segregated and incinerated on-site. |
Overburden (organic soil, waste material, tailings) |
1950 m3 |
N/A |
Soil (PHC) - surface staining - Areas of surficial staining to be excavated to an assumed depth of 1 m and disposed of in the on-site NHW facility. Excavated areas to be filled with borrow material and regraded to match surrounding landscape. |
Hazardous waste |
> 5 m3 |
The NHW will undergo long term monitoring (LTM) post remediation |
Asbestos - Abate, double bag and dispose of in the recommended on-site NHW facility. |
Hazardous waste |
> 100 m2 |
The NHW will undergo long term monitoring (LTM) post remediation |
Lead Amended Paint - Partial abatement on-site of poorly adhered paint and off-site disposal ofremoved paint at hazardous waste facility. Following partial abatement,materials with remaining well adhered paint will be treated with LeadDefender® and disposed of in the on-site NHW facility. |
Hazardous |
< 10 m3 |
N/A |
Batteries - Removal of batteries from vehicles and equipment, if present, and off-site disposal at a registered hazardous waste facility. |
Hazardous |
~134,100 L |
For incinerated remains disposed of in NHW, the NHW will undergo long term monitoring (LTM) post remediation |
Liquid - To be sampled and incinerated on-site if they meet incineration criteria. Residual ashes disposed of in the recommended on-site NWH facility following leachate analysis. Barrel contents unfit for incineration will be amalgamated and shipped off-site to a licensed facility for treatment and/or disposal. |
Hazardous waste |
16000 L |
For incinerated remains disposed of in NHW, the NHW will undergo long term monitoring (LTM) post remediation |
Aqueous Liquid - To be sampled and incinerated on-site if they meet incineration criteria. Residual ashes disposed of in the recommended on-site NWH facility following leachate analysis. Barrel contents unfit for incineration will be amalgamated and shipped off-site to a licensed facility for treatment and/or disposal. |
Hazardous waste |
unknown volume (m3) |
For wastes disposed offsite, no further treatment required. For wastes disposed in the NHW, the facility will undergo LTM post remediation. |
Hazardous Buried Debris - Classification of the WDAs in accordance with the AMSRP to designate each as a Class A, B or C and determine the appropriate remedial action prior to the remedial program. Dispose of as HW if indicated by results. |
