(This Sept 3 story has been refiled to clarify that the tariff cuts cover shipments to U.S. Gulf Coast destinations, in paragraph 4 )

HOUSTON (Reuters) - Pipelines that historically carry Canadian crude to the U.S. are cutting rates and looking to ship different grades of crude oil due to rising competition from the newly expanded Trans Mountain pipeline.
The moves will temporarily cut the cost of transporting some of Canada's heavy crude to the U.S. Midwest and Gulf Coast next month. U.S. imports of Canadian crude hit a record in July as Trans Mountain expansion (TMX) volumes grew.
Shipments on TMX started in May, sending up to 890,000 barrels per day (bpd) to Canada's Pacific Coast. About 80% of the volumes are contracted, leaving 20% available for spot shipments.
With more oil moving on TMX, Canadian pipeline operator Enbridge (NYSE:ENB) said in August it will cut its tariffs for September by 11% per barrel on heavy crude moving on its Mainline system to points on the U.S. Gulf Coast. The 3 million-bpd system ships the bulk of Canada's crude exports from Edmonton to the U.S. and is one of the main competitors to TMX.
The company is not rationing pipeline space for September for the first time in over a year, with sufficient capacity available to cover all nominated barrels.
Enbridge said it anticipates Mainline will be well utilized for the remainder of the year, attributing the decrease in volumes to routine oil producer and refiner maintenance.
