Notley was asked if an answer though could come out earlier in the month.
Former U.S. vice president Al Gore has waded into the Trans Mountain pipeline debate, siding with the First Nations and Canadian politicians fighting to stop the expansion project.
"I'm optimistic that we will be successful in that task", Notley said.
Speaking for Ottawa, Notley said the government is in "very serious and determined" discussions with Kinder Morgan, although she wouldn't reveal and details on the discussions.
Speaking to reporters in Edmonton, Notley announced Alberta is also seeking full status in the B.C. court reference case, announced last month by B.C. Premier John Horgan.More news: Southampton v Manchester City -- Fans' view

The City of Burnaby has applied to the Supreme Court of Canada for leave to appeal the construction of Kinder Morgan's Trans Mountain pipeline expansion project after lower courts and the National Energy Board rejected its challenge. But she wants to see any uncertainty about the project eliminated, and construction back on track this summer.
On Tuesday, Mr. Robertson told Bloomberg that the proposed Trans Mountain pipeline expansion will never go ahead "based on the resistance on the ground".
Along with the billboards, Notley will be writing an op-ed in BC media, in response to critical comments made by Vancouver Mayor Gregor Robertson. It would have the potential to cause gasoline and other fuel-related prices to spike in B.C. Parties on both sides of the House accepted an Alberta Party amendment to put a two-year limit on the bill.
"It also demonstrates a tremendous level of inward-attention", Ms. Notley added. On Wednesday, Kinder Morgan shareholders voted in favour of a non-binding proposal that would require audits of the company's environmental and legal risks. The Federal Court of Appeal refused to do so - and they did so without providing any reasons. The Federal Court of Appeal previously rejected appeals from the city and from the provincial government in March.
Notley has previously warned that B.C.'s delay tactics could bring consequences and her government is close to passing legislation that would give it the power to restrict oil shipments.
