Neptune Cargill Overpass Extension

Transcription

1 Project Environmental Review UPDATE November 23, 2017 Northshore Waterfront Liaison Committee Teck

2 Agenda Project Objectives Project Description Project Discussion VFPA PER process Project Review Status

3 Project Objectives Create free-flowing traffic access into the Neptune Terminal for trucks and construction equipment from Low Level Road off existing Overpass Access for upgrade works terminal coal updates (Allison project: new rail dumper, new conveyors, replacement shiploader, new track 0) Mitigate reduced access for emergency and large vehicles related to G3 Terminal construction and changes Enhance firetruck access Eliminate the use for the existing height restricted underpass Create an opportunity for track straightening at dumper area and reducing risk of train derailment

4 Project Description Components Construction from the existing two-span steel bridge using a new curved steel 66 m bridge length (824 m 2 ) above grade over the eastern terminal rail lines (Track 0 through Track 8) Curved bridge components, supported by 2 abutments and 1 pier on pile foundation over the span over the tracks Approach ramp will be 230 m in length (2,197 m 2 ), 6% grade from eastern coal stockpile area up to new bridge span Ramp will be constructed using light weight fill Overpass extension connected to existing surface drainage and stormwater pollution prevention and capacity Low impact construction on the existing facility operations, allow for consistent turning traffic movement Security Gate off Low Level Overpass

5 Location North Vancouver Existing Neptune Terminal VFPA lands

6 Location Connection to existing low-level road overpass Access into existing terminal developed site Create free flowing traffic access to Neptune site Mitigate reduced access

7 Existing Neptune Cargill Overpass

8 Visualization of Overpass Extension

9 Overpass Extension Seismic and geotechnical studies Archaeological assessment, and monitoring Pile supported bridge deck design consistent with existing overpass Light weight fill for ramp No preload Limited surface soil disturbance

10 Overpass Extension Construction Environmental Management Plan Traffic dust control - wheel wash Erosion and sediment control, air, noise, light management Traffic management

11 Project Schedule Project Environmental Review submission - Aug 30, 2017 Requested revisions Oct 2, 2017 Information Requests Oct, Nov 2017 Stormwater / Drainage, Security Gate, Construction Traffic Management Geotechnical investigative studies and Archaeological monitoring completed July 2017 Detailed design end of November 2017 VFPA PER Permit anticipated Dec Jan 2018 Construction January 2018 to September 2018.

12 Project Construction and Operations Effects / Issues Construction related air emissions, traffic, light and noise Water collected through existing water treatment system Geotechnical investigations monitored through environmental management plan and chance find protocol during drilling Construction environmental management plan to mitigate construction issues related to air, soils, noise, light and traffic Archaeological Overview Assessment conducted across entire Neptune terminal

13 Next Steps PER information requests and responses Detailed designs VFPA project permit, including conditions Retain Construction Contractor Ongoing communication with VFPA / NSWLC
