Citizens for Pennsylvania's Future, an environmental advocacy group, on Monday released what it calls a "plain language" guide to Act 13, Pennsylvania new oil and gas law, the first comprehensive attempt to regulate the industry developing the Marcellus Shale.

"Since this law was signed, there has been a great deal of confusion about the various provisions," said George Jugovic Jr., the president of PennFuture. The law includes provisions allowing government to impose an "impact fee" on shale-gas wells.

A summary and the full report are available online at www.pennfuture.org/marcellus.
