JACKSON, Wyo. (AP) — Bridger-Teton National Forest of?cials have delayed releasing a document that will decide the extent of a proposed natural gas development in western Wyoming.

The U.S. Forest Service had maintained that the supplemental environmental impact statement would be out by the end of June.

But this past week, forest spokeswoman Mary Cernicek tells the Associated Press that the plan is now due out in August.

The original environmental study on Plains Exploration & Production Co's proposed natural gas development near Bondurant was deemed inadequate last January.

The original plan was to drill 136 gas wells from 17 well pads.

The proposal has drawn opposition from conservation groups and area residents.
