Stanley Park Water Supply Tunnel - Chilco Shaft

The proposed amendment 

The Greater Vancouver Water District (GVWD, the Permit Holder) is planning to construct a new water main below the surface of Lost Lagoon at Stanley Park. This Project was captured under PER No. 19-046 – Stanley Park Water Supply Tunnel Chilco Shaft Area, however the Permit Holder has requested to amend the Project Permit to add additional scope components, amend condition #21 of the Project Permit to allow flexibility on the retention of existing utilities and extend the proposed completion date of the Project. The proposed changes to the existing Project Permit requires additional review to determine if the activities will result in significant adverse environmental effects.
