CHARLESTON, W.Va. (AP) -- West Virginia's Senate has approved a measure meant to improve safety around underground gas pipelines and well sites, but environmentalists aren't happy with the process.
They had cried foul over a change to the bill before senators unanimously voted to send it to the House of Delegates this week.
The bill adds to rules that govern oil and gas drilling. One provision would require companies to mark whether they've placed underground pipelines in mining areas. A surface miner was killed in 2006 when his bulldozer struck a gas pipeline in Boone County.
Another provision aims to prevent leaks of wastewater holding ponds at well sites. Some environmentalists object to an exception added to that language. Supporters say state regulators agree to that change.
