Protesters question Trudeau on Alton Gas project during Halifax visit

About a dozen protesters unhappy with a controversial natural gas storage project in Nova Scotia gathered outside of a Halifax seniors residence on Thursday morningduring Prime Minister Justin Trudeau'svisit to the city.

After meeting with seniors inside aboutthe federal budget, Trudeaustopped outside to speak with the protesters.Many of themcarried "Stop Alton Gas" signs.

Darlene Gilbert,a Mi'kmaw water protector, confronted Trudeau about the plan by Alton Gas tocreate underground cavernsto storenatural gas by flushing salt deposits with water and dumping the brine back into the Shubenacadie River.

Gilbert didn't pull punches with Trudeau.

"When are you going to stop poisoning our waters?" Gilbert asked the prime minister."We are saying take Alton Gas out of our province now. It's our waterways."

'I'm concerned for my generation'

It's the second time in two days that Indigenous protesters have taken Trudeau to task.

The prime apologized Thursday for how he responded the night before at a Liberalfundraiser in Toronto to aprotester advocating on behalf ofa northern Ontario First Nation struggling with historical industrial dumping upstream from the community.

In Halifax, Trudeau pointed out the federal government announced last month it isstepping in to regulate Alton Gas's plan to use water from the Shubenacadie River.

The proposed federal regulations for the Alton Gas project will be aimed at managing potential threats to fish, fish habitat and human health but the impact of these new rules remains unclear.

"I hearyou on this," Trudeau told Gilbert."I hear your emotions around this and I hear your anger."

"I'm not angry," Gilbert replied."I'm worried, I'm concerned for my generation.I have grandchildren and children."

Long-running controversy

For the past 12 years, Alton Gas has been planning to pump water from the river to an underground site 12 kilometres away, where it will be used to flush out salt deposits, creating up to 15 caverns.

The leftover brine solution would then be pumped back into the river over two or three years.

The project has been on hold since protests started in 2014, and a protest camp was set up near the river two yearslater.

Some members of the nearby Sipekne'katik First Nationhave argued the project will damage the 73-kilometre tidal river, which runs through the middle of mainland Nova Scotia.

Alton Gas, a subsidiary of Calgary-based AltaGas, has said it iscommitted to safe operations that will protect the Shubenacadie River.

"As designed and operated, we are confident that Alton will not have an impact on fish or fish habitat in the Shubenacadie estuary," the company said in a statement last month.
