British Columbia's premier is continuing her tough talk about Enbridge's proposed Northern Gateway pipeline project, but she says she's still not ready to make any conclusions about it.

Premier Christy Clark says officials from her government will pose questions about the project at the National Energy Board's ongoing joint review panel hearings, where the province has intervener status.

Clark said Monday she's still deeply concerned about a report issued last week detailing the environmental devastation caused by a massive oil leak from an Enbridge pipeline in Michigan.

The report outlined a list of failings by the company, both in the years leading up to the spill and during the disaster itself.

The province's Opposition New Democrats have said they are opposed to the project, but the governing Liberals have so far refused to take a position either for or against it.

Enbridge plans to construct a twin pipeline from the Edmonton area to Kitimat, on B.C.'s northern coast, where the crude oil will be shipped by super tankers to Asia.
