Depending on the groundwork done, at least 4 years to complete the EA phase, as ground investigations (geotech, Archaeology, land claims, SARA listed species, water quality, etc) will have to be done prior so they can be reviewed during the EA and information gaps identified. The companies can help themselves by applying for permits to study the potentiel routes now and hire local FN to help with the studies and share that information with all bands that have Land Claims/treaties along the proposed routes. Then another 6 months to a year to get through the technical design phase to get regulatory permits, major modules can be ordered up at this point which generally have a 18-36 month lead time.
Some key issues
Cumulative impacts from multiple projects in the terminal area and pipeline routes?
Is dredging required for the terminal and access routes, is the dredge spoil contaminated and if so with what and how much, then where does it go?
Are there marine shipping and sea mammal impacts? A Termpol needs to be completed
is the Terminal in a geohazard area or is their critical habitat in that area?
