PITTSBURGH — A new series of anonymous billboards on the Pennsylvania Turnpike describes critics of natural gas drilling as "Green Slime" who use "Lies" to discredit the industry.
The billboards don't disclose who was funding the campaign. But after The Associated Press began making inquiries, the Pennsylvania Independent Oil and Gas Association took credit.
Association president Louis D'Amico says they plan to expand the campaign. The billboards didn't break any laws, but some people inside and outside the industry say the debate over Marcellus Shale drilling should be transparent.
George Jugovic, president of the environmental group PennFuture, says it's ironic that a campaign which used phrases such as "Get The Truth" was started anonymously.
Steve Forde, a spokesman for the Marcellus Shale Coalition, says transparency in the debate is important.
