April 26 (Reuters) - The Canada Energy Regulator (CER)

has six leave to open applications left to consider for the

Trans Mountain pipeline expansion project, a CER spokesperson

said on Friday.

The CER has so far approved 36 out of 42 leave to open

applications received from Trans Mountain, covering pipeline

spreads, pump stations and tanker loading facilities.

Each section of the pipeline, which is expected to start

transporting oil on May 1, requires leave to open before it can

begin operating.
