accordance with the Fish Plan filed with the Minster to fulfill the requirements of Section 10 of the BSTA (the Environmental Management Plan and Consultation Process).
The tentative work activity schedule can be seen in Table 3, located in Section 5.1. It is important to note that the PAR and utilities need to be constructed as soon as possible and therefore before the new channel can be constructed. As a result by-pass pumping for this segment of the existing drain will commence in early May and extend until the new realignment is complete and flows can be switched to the new channel. Building and then tying the existing channel into the new channel was considered, however based on a limited work area and the importance of other construction elements (PAR and utilities installation) this will not be practical or feasible. The sheet piling to be used in the newly realigned channel is considered a special order item and therefore has a long lead time. These materials were ordered when the design was finalized and therefore the delivery of the sheets has been set back to early July.
All of the dates that have been provided in the following tentative work activity schedule are best estimates which are contingent on various items including third party construction works (e.g. Union Gas) and interrelated construction elements. It is possible that the dates provided may vary as the project progresses. Despite any unforeseen changes to the schedule, work within the Detroit River will adhere to the warm / cool water fisheries timing window (no in-water work between March 15 and June 30) implemented by DFO. Notification will also be sent to DFO 7 working days prior to the commencement of any work within the Detroit River.
