Burnaby Mountain Tunnel Construction Noise Management Plan

Trans Mountain must file with the NEB for approval,

at least 3 months prior to

commencing Burnaby Mountain tunnel construction activities

, a Burnaby Mountain

Tunnel Construction Noise Management Plan that includes:

a) proposed hours of daytime and nighttime work;

b) baseline daytime and nighttime ambient sound levels at noise sensitive areas

within 500 metres of the entry and exit sites for the tunnel;

c) predicted noise levels at the most affected receptors caused by tunnel

construction without mitigation measures implemented;

d) proposed noise mitigation measures, including all technologically and

economically feasible mitigation measures;

e) predicted noise levels at the most affected receptors with mitigation measures

implemented, including noise contour map(s) showing the potentially affected

receptors;

f) a tunnel construction noise monitoring program, including locations,

methodology, and schedule;

g) criteria that will be used to determine when tunnel construction would be shut

down due to noise;

h) a summary of its consultations with Appropriate Government Authorities

and any potentially affected receptors (residences and businesses), as well

as copies of all written comments that may be provided to Trans Mountain by

those consulted. In its summary, Trans Mountain must provide a description

and justification for how Trans Mountain has incorporated the results of its

consultation, including any recommendations from those consulted, into the

Plan;

i) a description of the public and Aboriginal communication and noise complaint

response processes; and

j) a contingency plan that contains proposed mitigation measures for

addressing noise complaints, which may include the temporary relocation of

specific residents.

Groundwater Seepage Management Plan – Burnaby Mountain tunnel construction

Trans Mountain must file with the NEB for approval,

at least 3 months prior to

commencing Burnaby Mountain tunnel construction activities

, a Groundwater

Seepage Management Plan for tunnel construction. The plan must include:

a) an estimate quantifying the anticipated average and maximum amounts of

groundwater seepage into the tunnel, and an assessment of any potential

impacts on the water table;

b) a discussion of Trans Mountain’s proposed pumping, treatment, and disposal

options;

c) a description of the potential effects of dewatering of bedrock aquifers,

springs and streams on local groundwater and surface water resources, and of

measures that Trans Mountain would implement to mitigate such effects;

and

d) a description of measures that Trans Mountain would implement during the

operations phase in the event that there is groundwater seepage into the tunnel.

Project organizational structure for Project construction

Trans Mountain must file with the NEB,

at least 2 months prior to commencing

construction

, a diagram of the Project’s organizational structure (i.e., project

management, design, and field staff) that clearly identifies roles, accountabilities,

responsibilities, and reporting relationships for construction of the applicable Project

components.
