May 14 (Reuters) - The Canada Energy Regulator (CER) on

Tuesday said it had issued an order to TC Energy's ( TRP ) NOVA

Gas Transmission Ltd (NGTL) to further reduce the operating

pressure for the Grande Prairie Mainline gas pipeline near

Edson, Alberta.

A section of the NGTL gas pipeline system in Alberta was

ruptured and caught fire on April 16, sparking a wildfire in a

remote area of Yellowhead County.

Last month, TC Energy ( TRP ) said its NGTL gas pipeline system has

resumed normal operations. The cause of the rupture was under

investigation.

The pressure reduction will be in place until NGTL

demonstrates the Grande Prairie Mainline pipeline is safe to

operate at a pressure above the restricted operating pressure

outlined in the inspection officer order, the CER said.

"Currently we do not have any service restrictions on

the NGTL System and we do not anticipate any service

interruption to natural gas delivery," TC Energy ( TRP ) said in a

statement.

The NGTL is TC Energy's ( TRP ) natural gas gathering and

transportation system, which transports gas produced in the

Western Canadian Sedimentary Basin (WCSB) to markets in Canada

and United States.
