Sunoco Logistics Partners LP confirmed that a contract employee was killed on Monday during work to convert the Marcus Hook industrial complex near Philadelphia into a natural gas liquids (NGL) terminal.

Spokesman Joe McGinn said the contractor, whose name was not released, died in an incident at about 2:30 p.m. EST Monday. The worker reportedly died of blunt force trauma after a large pylon fell. No other injuries were reported.

A U.S. Occupational Safety and Health Administration (OSHA) representative said federal officials are investigating. OSHA said the contractor worked for Los Angeles-based engineering and construction services firm AECOM, which has been cited for several OSHA violations in the past, according to agency records.

“The worker was struck by a steel pile during pile-driving operations,” said OSHA spokeswoman Joanna Hawkins. She added that the federal investigation could take up to six months to complete.

“No words can express the sorrow and pain that come when such a tragic event happens,” Sunoco stated. “Our deepest sympathies go out to the family and friends of the individual who died. They have suffered a devastating loss.”

Sunoco is converting the former oil refinery on the Delaware River into a terminal to store, export, process and distribute NGLs (see Shale Daily, Dec. 5, 2013).
