Integrated Services Save Time and Money in Demolition of 55-Year-Old Pulp and Paper Mill

In 1910, Prince Rupert was incorporated as an industry town as it became the final Western Canadian destination for goods bound for Asian markets. During WWII Prince Rupert was a key military post, but once the war ended in 1945 it was left in a state of change as military personnel left.

In 1951, a pulp mill opened on nearby Watson Island and became the main employer and revenue generator for the City of Prince Rupert. For over 50 years this facility produced forestry pulp products for international markets. During this time the facility was renovated and upgraded leading to a mixture of construction techniques and materials. In 2010 the facility closed.

The City of Prince Rupert decided to redevelop Watson Island into a trade hub driven by its access to railway, water and road transportation. With the changing energy landscape, Pembina recognized the potential to develop a Liquid Propane Gas Export Terminal on this well-connected site.

The first step to begin redevelopment was to remove the existing infrastructure. Due to the age and nature of the facility, there were se­veral types of materials that were used including those containing asbestos. Tervita’s experience in demolition, hazardous material abatement, chemical handling, recycling and landfill management made our team the first choice for this complex project.

Tervita Equipment Demolishing Obsolete Paper Mill

Our experts completed an in-depth assessment of the site to determine the safest way to systematically remove the structures while using the existing buildings for site operations to minimize both mobilization time and cost to the City. Our commitment to the protection of personnel, the public, the environment and equipment was apparent in every stage of the project. There was still equipment existing onsite when the project began and Tervita worked to safely remove each piece to be sold and recuperate costs for the customer where possible.

The above-ground facilities included 56 structures that required removal. The goal of the project was to properly dispose of or recycle materials and salvage anything of value that could be sold for scrap. With Tervita’s integrated metals recycling expertise we were able to offer a greater level of knowledge in the separation of materials and resale.

In addition to the demolition scope, Tervita operated the onsite landfill which allowed us to better manage debris and asbestos waste, reducing the need for offsite disposal. Our creative solution for waste management increased environmental safety by reducing the transportation of hazardous asbestos to city landfills and reduced project costs by maximizing the use of onsite resources.

Tervita Demolition of Paper Mill Conveyer One of the main challenges faced were the four wood chip conveyor belt galleries that crossed above a CN Railyard. Tervita had to manage the removal by crane, working in limited windows of time, to avoid impacting rail operations. By using our extensive fleet of specialized demolition equipment we were able to minimize the amount of specialty equipment rentals required.

The presence of both bunker C fuel oil (heavy oil used for heating) and chemical process piping required our team's knowledge of safe handling and disposal to stabilize, drain, clean and dispose of the chemicals and associated pipes and storage tanks.

In the end, Tervita removed 500,000 litres of Bunker C fuel for proper disposal, removed and recycled 15,000 tonnes of subsurface concrete crushed to 3” minus aggregate, removed and disposed of 35,000 tonnes of unrecyclable subsurface concrete and segregated and recycled 1,500 tonnes of metals.

By integrating our expertise in demolition, hazardous materials, waste management, landfill operation and metal recycling, we were able to create and execute a plan that saw the project safely through to completion in four months. With each project we undertake, our goal is to minimize your impact and maximize your returns by offering greater efficiencies to help improve schedules and reduce overall costs.
