Companies respond to claims of unmarked pipelines

Pipeline explosion near Darrouzett

AMARILLO, Texas (AP) - Two pipeline companies are defending themselves after a federal official said the lines weren't marked before two deadly explosions last month in Texas.

Two workers were killed after a bulldozer hit a pipeline June 8 near Darrouzett in the Panhandle. One drill operator died in the June 7 blast near Cleburne in north Texas.

DCP Midstream, the Panhandle pipeline's owner, says it can't find evidence that the construction company followed notification procedures before the project started.

But Nick Thomas, the construction company owner, says the line was marked and it was an existing excavation site.

Enterprise Products, which owns the pipeline near Cleburne, says an employee tried to mark the line but couldn't find the project site.
