Documents show the volume of gas flared at the LNG Canada plant on British Columbia's north coast between October and January far surpassed what its permit allows.
University of Victoria air quality researcher Laura Minet obtained monthly air emissions reports filed by LNG Canada to the B.C. Energy Regulator under freedom of information proceedings.
The reports break down the flaring source into three categories: warm/wet, cold/dry and storage and loading.
During the four-month period covered in the filings, warm/wet flares exceeded permitted volumes by 45 times on average, cold/dry by 40 times and storage and loading by five times.
Natural gas is piped to the plant in Kitimat, B.C., and chilled into a liquid, enabling it to be shipped in specialized tankers across the Pacific to energy-hungry Asian markets.
An LNG Canada spokesperson says in an emailed statement that the facility is in the early operations phase and increased flaring is a normal occurrence, but in regular operations, flaring activities reduce significantly.
It's the first facility of its kind in Canada and its owners — Shell and four Asian companies — are contemplating doubling its capacity in a second phase, which has been chosen for a speedy review under the new federal major projects office.
First cargoes departed the project's initial phase last summer.
Ten community notifications advising of "flaring events" have been posted by LNG Canada since the beginning of March.
One on Tuesday lasted three hours, advising nearby residents of a flare height of 10 to 15 metres with "associated noise and visible emissions."
Environmental and health-care groups have been raising concern about the potential health impacts of pollutants released through flaring. Publicly available air quality monitoring data has shown that pollutants like nitrogen dioxide and sulphur dioxide have been consistently low over the past year, LNG Canada said.
"Flaring is a provincially regulated safety measure that ensures the controlled, efficient combustion of natural gas during specific operational phases. It is a critical part of safely operating a facility of this scale and is not expected to be routine during regular operation," LNG Canada said in the public notice.
Minet, who leads the Clean Air Lab at the University of Victoria, has researched flaring at various LNG export facilities around the world, so she decided to seek out data from Canada's first project after it started up.
"All the numbers are higher than the permits and they've been consistently higher since last September at least," she said. "They should comply with the flaring permits. It's surprising that they haven't consistently for many, many months."
Minet's research has found that LNG facilities worldwide have startup phases characterized by large amounts of flaring and lasting two years on average.
"What it's telling me is that we need to account for this high flaring volume in environmental impact assessments," she said.
