This document provides a response to review comments comments from the BC Ministry of Environment and Climate Change (ENV). This addendum to the Phase 4 report contains a list of corrections/changes for the report. The corrections are for mostly typographical errors in the report and the changes have been noted to improve the clarity of the report, as suggested by ENV. The conclusions of the Phase 4 report are not impacted.
ENV provided the following general comments in their review letter, in addition to the specific points addressed in the addendum:
“The phase 4 risk assessment has been completed to Integral Consulting Inc.’s usual high quality standard
and provides an authoritative and comprehensive human health risk assessment for Trail smelter
related metals other than lead.
The ministry accepts and is in general agreement with the conclusions of the Phase 4 risk assessment in
Trail and notes that this most recent and final HHRA for the site serves to confirm and further
delineate the conclusion of elevated human health risk related to environmental exposure to
metals in Trail, reached in previous risk assessments for the site.”
