When a site is in the way of a pipeline

There’s a tense relationship between development and archaeology in British Columbia. Building in or extracting from land that’s been occupied for millennia inevitably means that the new must confront the old.

Because archaeological sites are protected by the Heritage Conservation Act, identifying and recording these heritage places is a common precursor to logging, mining, construction or other kinds of impacts.

On one hand, development-driven archaeology allows us to find sites we never would otherwise know about. On the other hand, the sites we find are at very likely to be destroyed.

So what happens when archaeological impact assessments succeed at finding archaeological sites, and those sites are in the way? What happens to the sites? And who decides?

For many kinds of development, design changes can protect the most significant parts of sites. A forestry cutblock boundary, for example, can be adjusted to exclude sites. For infrastructure projects, special berms or overpasses can be worked into plans to reduce impacts—the TransCanada Highway near Chase, or the South Fraser Perimeter Road in through Surrey and Delta, have good examples of this.

For other kinds of projects that can be hard to reroute or reduce impacts (like an open-pit mine or a linear right-of-way), it’s often necessary to remove the site entirely, an option that’s referred to as “mitigation”.

The concept of mitigation is common in environmental assessments: it refers to lessening the impact of a project on something that’s valued. You can mitigate pollution impacts on air quality, for example, by using scrubbers.

For archaeological sites, which are fragile and non-renewable, mitigation usually means carefully removing the site through controlled excavation. We’re meant to be mitigating the impact to the archaeological record by extracting data that will survive the site: replacing the actual site with its scientific reflection.

This assumes that the ultimate value of archaeology is informational—what we can learn from it—and positions archaeologists, with our special skills and methods, as the most qualified to manage and decide the fate of sites.

But there are other kinds of heritage value too, social and cultural values that Indigenous descendants and inheritors of the sites may have. Indigenous communities are consulted on these values in a cursory way, but generally have little influence over outcomes for their own heritage.

So what happens, for example, in the context of the Coastal Gas Link pipeline planned in northern BC, where Indigenous rights and industrial development have clashed?

In that case, the more than 60 archaeological sites found around the right-of-way (with more still at camps and laydowns) will be gone by the time the pipe is in the ground.

Those sites—the physical manifestation of millennia of occupation that gives rise to Indigenous rights and title—won’t be allowed to get in the way of the pipeline. They will be dug up, treated more like contaminated soil to be removed than like the irreplaceable pieces of human history they are.

I wish I could say that archaeological management worked out for everyone. I wish I could say that government and developers seek, and obtain, Indigenous consent to destroy the sites that are their cultural inheritance. I wish I could say that what we lose in physical heritage we gain in knowledge.

But most of the time we don’t. Most of the time, the most salient outcome of an archaeological impact assessment is a bag of artifacts that gathers dust in a museum, and an expert report that allows development to proceed with a clear conscience, having checked all the boxes that law demands.

So often in BC, archaeology has become a tool to remove a problem. Until we can deal with that problem head-on, archaeology’s potential to expand knowledge and generate interest and foster understanding will be wasted.
