The Westridge Pipeline delivers from above-ground storage tanks at Burnaby Terminal to tankers at the Westridge dock using delivery booster pumps at the terminal to achieve the desired loading rate. The rupture occurred at Kilometre Post 3.10 on the Westridge Pipeline at an elevation of approximately 74 m asl. The Westridge Dock, at an elevation of approximately 4 m asl, includes above-ground tanks and associated equipment for the delivery of crude oil to tanker vessels (see Appendix A). The Westridge Pipeline is approximately 4.13 kilometres (km) long and terminates at the Westridge Dock. The Burnaby Terminal comprises numerous above-ground storage tanks, piping, and valves and is at an elevation of approximately 160 metres (m) above sea level (asl). The Westridge Pipeline initiates at the Burnaby Terminal, the termination point of the Trans Mountain Pipeline system. The Westridge Dock Transfer Line (Westridge Pipeline), constructed in 1953, is a 610-millimetre (mm) outside diameter (OD) crude oil pipeline with a nominal wall thickness of 6.4 mm and a maximum operating pressure (MOP) of 3366 kilopascals (kPa).

Two members of the public were also sprayed. There were no explosions, fires, or injuries resulting from this occurrence however, emergency workers and two firefighters responding to the incident were sprayed with crude oil. Eleven houses were sprayed with crude oil many other residential properties required restoration and approximately 250 residents voluntarily left their homes. Crude oil flowed into Burrard Inlet Bay via the Burnaby storm sewer system. When the pipeline was punctured, approximately 234 cubic metres of crude oil was released, approximately 210 cubic metres of which was recovered. and operated by Kinder Morgan Canada Inc., was struck and punctured by a contractor's excavator bucket while the contractor was excavating a trench for a new storm sewer line along Inlet Drive in Burnaby, British Columbia. At 1231 Pacific daylight time on 24 July 2007, the 610-millimetre (24-inch) Westridge Dock Transfer Line, owned by Trans Mountain Pipeline L.P.
