Two pipeline workers were injured in a construction accident on Sunoco Logistics’ Mariner East 2 pipeline about 35 miles east of Pittsburgh late Sunday.

The workers, one male and one female, were pulling a piece of equipment through a section of the pipeline under a road when the equipment struck and injured them, said Lenore Uddyback-Fortson, a spokesperson for the U.S. Occupational Safety and Health Administration, in an email. OSHA is investigating.

The equipment, called a pig, is used to clean out the insides of pipelines.

The female worker was treated and released and the male has a broken arm and remains hospitalized but in stable condition, Uddyback-Fortson said.

The accident occurred at 11:16 p.m. Sunday night, near the intersection of Main Street and Gombach Road, according to Westmoreland County 911.

The workers were employed by Precision Pipeline, an Eau Claire, Wisc.-based pipeline contractor. Company officials didn’t immediately respond to a request for comment.

Penn Township manager Alex Graziani said the accident occurred along the route of the Mariner East 2, which is being built through the middle of the township.

The 20-inch pipeline will carry natural gas liquids from Western Pennsylvania to a port facility near Philadelphia.

Representatives from Energy Transfer, Sunoco’s parent company, did not immediately respond to requests for comment.

The Pennsylvania Department of Environmental Protection suspended construction on the Mariner East for 30 days last year because of repeated permit violations, including dozens of drilling mud spills, and fined its developer $12.6 million.

The company says the pipeline is expected to begin carrying gas by the end of the year.
