Schedule construction activities near residential areas, community facilities (e.g., golf courses,

parks), or privately owned businesses during the period from 7:00 am to 7:00 pm, or in

accordance with applicable noise bylaws or approval conditions. Note that some construction

activities, once started, must continue on a 24‑hour basis (e.g., an horizontal directional drill

("HDD") may be continuous until completion). In the event of afterhours noise during construction

(e.g., potential use of generators at HDD sites), Enbridge will ensure affected landowners are

notified in advance and any required approvals are obtained.

An assessment of the biophysical and socio-economic elements for deviations that are greater than

50 meters from the center line of Enbridge’s proposed route is anticipated to be filed on August 15,

2016. It is anticipated that the Enbridge Environment and Socio-economic Assessment ("ESA")

conditions for these route deviations are similar to those previously described in the ESA [NEB

Filing ID: A74508-2], given that the route deviations are relatively short and close to the proposed

replacement pipeline route. As such, it is further anticipated that significance conclusions of the

ESA will remain unchanged for potential Project effects and cumulative effects.

In the event that watercourse construction activities need to occur within the instream restricted

activity timing windows, a qualified fish biologist, in consultation with the appropriate regulatory

authority, will determine appropriate mitigation measures. These may include assessing the

crossing location for the presence of fish and mussels prior to construction work beginning,

conducting fish and mussel salvage from the work site, and relocating fish and mussels to suitable

nearby habitat. In addition, Enbridge will reduce instream work duration by ensuring all equipment

and supplies are on site prior to commencement to the extent feasible, completing work in as little

time as possible, and maintaining the natural volume of stream flow at all times. All activities will be

in accordance with approvals from the appropriate regulatory authorities. A qualified fish biologist

will be available, as needed, during instream construction activities to provide advice to reduce

impacts and ensure compliance with regulatory approvals.

The proposed mitigation for the Project will avoid vegetation clearing during the pre-volant period

when bats are less resilient to disturbance. Sensory disturbance as a result of construction activities

will be temporary. The proposed mitigation to avoid operation of heavy equipment between dusk

and dawn will reduce potential for sensory disturbance of roosting bats.

To date Enbridge has not consulted on noise levels associated with HDD activities to directly

affected landowners. Once construction drilling rig specifications are finalized including anticipated

noise levels, Enbridge will further consult with directly affected landowners within 200 m of the

HDD location on the noise levels and appropriate mitigations as previously outlined in Enbridge’s IR

No.2 response

2.26 a.3, as well Section 6.0 of the Preliminary Enbridge Environment Protection

Plan [NEB Filing ID A5D8Y1].

Pre-Construction In Progress Enbridge Land Services Enbridge has undertaken HDD consultation with all landowners within 1000m of

the HDD drill locations. All directly affected landowners with residences within

150m of the HDD entry and exit points shall receive a form of compensation to

mitigate impacts associated with increased construction traffic and noise levels

during the HDD drilling activities. Landowner concerns raised during HDD activity

will be addressed and mitigation measures from the EPP will be utilized.

Prior to HDD activity, an Enbridge representative will make reasonable efforts to contact the

landowner a minimum of seven days in advance of startup. We will then work with the landowner

to discuss access, estimated compensation for potential impacts, determine a preferred work

schedule, review Enbridge Environment and safety considerations provide Enbridge contact

information, and address any questions and property-specific concerns.
