BILLINGS, Mont. — Opponents of the Keystone XL oil pipeline from Canada said the Trump administration is understating the potential for the line to break and spill into water bodies such as Montana’s Missouri River, as the U.S. State Department held the sole public meeting Tuesday on a new environmental review of the long-stalled proposal.
Backers say the $8 billion project would create thousands of construction jobs and boost local tax revenues. Sponsor TC Energy insists the line would be safe, despite spills on other lines operated by the company.
A federal judge blocked it last year, saying more environmental study was needed.
President Donald Trump issued a presidential permit for the line in March in a bid to avoid another unfavourable court ruling.
The Republican has been a strong supporter and revived the project after it was rejected under President Barack Obama, in part over worries it would make climate change worse.
Tuesday’s meeting, held at a conference centre in Billings, was not a public hearing and attendees were invited to use computer terminals to submit formal comments. But the event briefly turned into a shouting match between pipeline backers and opponents, reflecting Keystone XL’s emergence as a political lightning rod since it was first proposed in 2008.
Keystone supporter Todd Tibbetts said the line would cross through his farm near Terry, Montana. Tibbett is already getting paid by project sponsor TC Energy for a pipe storage yard the company built on his property.
“Keystone is a wonderful neighbour,” he said. “Yes, there’s a risk of an oil spill. We have to be willing to take a risk. It’s a very minuscule chance.”
Montana state Sen. Frank Smith says the 1,200-mile (1930-kilometre) line would break eventually. The Democrat worries that could foul downstream drinking water supplies on the Fort Peck Indian Reservation.
“Obama did a really thorough investigation and decided it wouldn’t work,” Smith said. “If it gets into (downstream water supplies) how long will it take to flush those lines out?”
Smith and other pipeline opponents criticized the format of the meeting, which included a designated “free speech area,” located just outside of the convention centre in a snowy parking lot in subfreezing temperatures.
Keystone XL would be a 36-inch (91-centimetre) wide pipeline that would help transport up to 830,000 barrels (35 million gallons) of crude daily from western Canada to terminals on the Gulf Coast.
Burning that oil would release annually between 2.3 million and 196 million tons (2.1 million up to 178 million metric tons) of additional greenhouse gas emissions that contribute to climate change, according to the State Department analysis. That’s equivalent at the high end to almost 3% of total U.S. emissions.
The broad range reflects uncertainty over how much crude from Keystone XL would displace existing oil supplies.
Rivers crossed by the line include the Missouri and the Yellowstone, which has twice experienced major oil spills. Both are prone to scouring during flooding. That means the river bottom gets scraped by the floodwaters, leaving buried pipelines exposed.
TC Energy spokesman Terry Cunha said Keystone XL would be tunneled at least 25 feet (7.6 metres) beneath major riverbeds to protect from accidents. He said the entry and exit points for the line would be set back from the bank to account for erosion.
“The studies continue to demonstrate or highlight that the project can be built safely, and that is our key priority,” Cunha said.
