Environmental Findings
- Multiple media impacted above federal
guidelines (2009-2012 investigations):
– Soil – benzene, PHC F1-F3, PAHs, metals – Groundwater – benzene, toluene, ethylbenzene, PAHs, metals, nitrite – Sediment - PAHs, metals – Surface Water - metals
- Estimated 6490 m3 of contaminated soil
and sediment, primarily related to landfill
SLIDE 6
Species-at-Risk Implications
- Draft CEAA Screening completed in 2011
in support of remedial planning identified SAR in vicinity of Site
- Primary SAR concern was excavation
within proposed critical habitat of Oregon Spotted Frog
- CSC initiated discussions with multiple
stakeholders
SLIDE 7
Species-at-Risk Implications
- CSC required to submit a permit for the
remediation project under Sec. 73 of SARA due to the potential to affect a listed species and their critical habitat.
Score: OSF 1, CSC 0
SLIDE 8
SARA Permit
- Set out conditions for the remediation
project that were incorporated into the tender specifications, including:
– Project timing/window (August 1 – Sept 15) – Wildlife fencing – Isolation of surface water in work area – Supervision and salvage by approved Environmental Monitors – Soil handling
