Engineering Firm Proposes Lateral Expansion of Foothills Boulevard Landfill to Extend Its Lifespan

In a recent committee meeting, representatives from Tetra Tech revealed a promising opportunity for the Foothills Boulevard landfill, operated by the Fraser Fort George regional district. The firm has proposed a lateral expansion of the existing landfill cell, which could enhance its capacity by nearly one million cubic meters. This development would effectively delay the construction of a new landfill cell by an estimated nine years, allowing for significant cost savings.

Currently, the landfill's Cell 1 has around 500,000 cubic meters of airspace remaining, which is projected to last for about four more years. This duration exceeds the original 2025 end-of-life prediction established in a landfill management plan from 2010. As Tetra Tech explored the design for a new cell, they identified a low area that could accommodate an expansion of Cell 1, thereby optimizing both space and resources.

The proposed expansion is estimated to incur costs of approximately $8-9 million, presenting a more economical alternative to the projected $15.7 million for constructing new cells 2A and 2B. Despite the benefits, expanding Cell 1 will require the construction of a new access road and adjustments to the existing gas extraction infrastructure. Tetra Tech’s design will also need to comply with current British Columbia landfill criteria, integrating future stormwater management needs alongside Fortis BC’s renewable natural gas project.

While the Ministry of Environment and Parks has shown no objections to the expansion, further steps must be taken to update the landfill's design, operational, and closure plans. Regional district staff confirmed that preliminary work for the new cell remains applicable, albeit delayed due to Cell 1’s expansion.

In conjunction with the landfill operations, Fortis BC representatives discussed how the expansion impacts their plans for harvesting renewable natural gas from the site. The repositioning of their equipment required adjustments to the planned pipeline route but promises to simplify some civil works. Fortis BC is committed to constructing its facility by 2027, transforming raw biogas into usable methane for their natural gas system while also flaring non-compliant gases.

Amidst these developments, Fortis BC is making a concerted effort to hire indigenous workers during the construction phase, reflecting a commitment to community engagement. Currently, renewable sources contribute about 5% to Fortis BC’s natural gas supply, with potential expansion to 15% in the future. The collaboration between Tetra Tech, the regional district, and Fortis BC illustrates a forward-thinking approach to managing waste and renewable energy resources effectively.
