Cumulative effect

impacts
Key issues
Implementing traffic management controls to respect critical timing requirements of these other projects
Carefully selecting appropriate work site access and egress locations
Monitoring of traffic levels and operational performance across the proposal footprint to consider cumulative effects
from these other projects.
There would therefore be a need to manage the interfaces of the construction staging and programming of this proposal
in combination with the above projects to ensure impacts are minimised.
Certain activities associated with this proposal would generate construction noise and vibration levels that would
temporarily exceed the applicable management levels (refer to section 6.2.3), which have the potential for amenity and
sleep disturbance impacts on adjacent sensitive receivers.
Additional temporary construction noise and vibration impacts will likely occur as a result of construction of the projects
listed in Table 6-68. The timing and location of any exceedance will depend on the construction staging and
programming of the above projects, and specifically, the equipment that will be used in a given location at a given time.
Some of the projects will be constructed in locations within and adjacent to this proposal’s footprint (refer to Table 6-68).
As such, there is the potential for sensitive receivers to be affected by construction noise and vibration generated from
multiple projects. This may increase the length of time some receivers would be impacted and would ultimately depend
on the timing and staging overlap between these other projects and this proposal. There is also a remote potential for
additive noise impacts to occur through noisy equipment operating at the same time. As such, there is the potential for
longer periods of sleep disturbance and/or amenity impacts. Therefore, the timing and programming of this proposal
needs to be considered in regard to the potential for cumulative noise and vibration impacts.
Safeguards and management measures to avoid and/or minimise impacts of the proposal on noise and vibration are
provided in Section 6.2.5. Safeguards and management measures to minimise cumulative noise and vibration impacts
would be included in the NVMP for the proposal which would be incorporated into the CEMP. Relevant safeguards and
management measures would include:
Selecting appropriate plant and equipment for construction activities
Timing certain activities to take place to avoid additive noise impacts
Managing the length of time people would be exposed to exceedances of the noise management levels
Revising the background noise and vibration levels through the committed background monitoring undertaking prior
to and during construction and revising the management measures accordingly.
