(1996). The bridges would be installed according to the DFO Operational Statement for
Clear Span Bridges, the issued MNR permit(s) and any additional conditions required by
MNR.
o
Birch River and Dead Dog Creeks are major crossings and will be designed as clear
span structures (~35 m for Birch River bridge; ~12 m for Dead Dog Creek bridge, to
be confirmed in applications that will follow the EA process), with site specific
engineering drawings that comply with MNR and DFO standards. The bridges will be
constructed in winter along with all of the other construction phase work. Bedrock
that is excavated to construct the bridge abutments will be used as rip rap and to
surface the approaches for water crossings. This material may be crushed if
required. Blasting activities will be in accordance with Wright and Hopky (1998) and
the portable crushing contractor will conduct work in accordance with provisions of
the Environmental Protection Act.
Utilize a rock truck (with a heated box) to import aggregate and use the excavator to place it
over the installed culverts. Aggregate would be removed from the nearby FAPs for
construction as needed for use on the FMP approved road (refer to Definition of Terms)
only.
Aggregate that is required for the road beyond the FMP approved road will be sourced
from either existing excavations on GCU’s patents or from an existing aggregate pit that
is licensed in accordance with the Aggregate Resources Act. The governing policy is
provided at the following link:

One of the reasons GCU has included engineered square timber bridges as an option is
because they require very little aggregate when installed.
Aggregate that is used for rip rap or erosion protection will be screened to remove fines and
ensure that it is cobble size material.
Concurrent with the timber harvesting and road construction from the end of the Wenasaga
Road, GCU would commence timber harvesting and road construction from GCU’s camp
using heavy equipment that is currently in place at the camp.
Utilize rig mats / swamp mats or an ice bridge to cross the Birch River with heavy equipment
at the bridge location to begin the bridge installation. The DFO Operational Statement for
clear span bridges would be followed. Alternatively, GCU would access the east abutment
using the equipment that commences work at GCU’s camp.
Approximately January 5 to March 15
Finish constructing the Birch River bridge in accordance with the engineering design
drawings, DFO’s Clear Span Bridge Operational Statement and any additional conditions
required by MNR. There would be no structures below the normal high water mark. Although
the crossing is not regarded as navigable except during unusually high water conditions, the
bridge would be high enough to allow passage of boats beneath it and in accordance with
requirements from Transport Canada.
Place black muck (sourced from within road corridor) on the embankments of the placed
road fill near the bridges and spread a seed mix with no invasive species before covering the
surface with straw mulch, all in accordance with proven best management practice on
