The Berth Two and Lynn Creek Estuary Offset Project - PER #21-068

Construction at berth two is anticipated to take 26 months and construction at Lynn Creek estuary is anticipated to take three weeks, with the majority of the activities occurring within the standard port authority construction days and hours (i.e., Monday to Saturday, 7:00am – 8:00pm).

As part of our permit application, Neptune has requested permission for extended hours because some construction activities may need to be done outside of the standard days and hours at points throughout construction. As we have done with previous projects, should extended construction activities be required and permitted, we will limit construction to low impact activities and will proactively notify neighbours in advance of these activities getting underway.

While construction activity will require vehicle traffic to transport equipment, supplies and construction personnel, site access will either be from the existing Low Level Road to berth two or by barge to berth two and the Lynn Creek estuary. As a result, we anticipate minimal, if any, impact to our adjacent residential, industrial, commercial neighbours, or vessel traffic.

Neptune will closely monitor noise levels at both sites to ensure construction activity does not result in a noticeable increase to average existing noise levels.

The demolition of the shiploader and related berth, as well as the subsequent pile driving activities at berth two will be the primary sources of noise during construction and may result in noise extending beyond the terminal perimeter. It is anticipated that these activities will take six to eight months to complete.

Neptune will limit impact pile driving to the standard port authority construction days and hours only and will use a variety of methods to further minimize noise, including: turning off diesel engines and using electric power whenever possible, combining the use of strobe lights with lower volume back-up alarms on construction vehicles when appropriate, and avoiding the use of high-noise power tools during structural steel construction.

Neptune will also follow noise reduction best practices for the Lynn Creek estuary marine activities.

Neptune has two offsite noise monitoring stations that will be active throughout construction and also has a comprehensive process in place to investigate and address noise concerns, including identifying the noise source – whether from construction activities, existing operations or something else – and putting appropriate mitigations in place.

In most cases, additional lighting will not be required as the majority of construction activities will happen during daytime hours. When additional lighting is needed for safe work practices, lighting will be positioned down and away from residential areas to focus only on work areas and shields will be used for welding.
