Laramie, WY – Two oil and gas pipeline accidents this month brought national attention to the safety of wyoming's growing infrastructure of pipelines. In one incident, a bulldozer hit an older pipeline, although there's no official news yet on the cause of those accidents. But federal regulators say better coordination among industry, government, and the public could help reduce the number of accidents. Tom Barrett heads the federal pipeline and hazardous materials safety administration. He says legislative efforts are underway to renew and improve the federal pipeline safety act. But he also says state-based pipeline safety hotlines, called one call centers, could go national. Barrett says pipeline accidents have been decreasing overall since industry and governments stepped up safety programs. But he says he still sees room for improvement when it comes to residential gas line safety.
