FAIRBANKS, Alaska (AP) — The U.S. Army Corps of Engineers released a 500-page report on the Point Thomson gas project in the final step needed before the federal government can give ExxonMobil Corp.’s North Slope project the go-ahead.

The Corps released its environmental impact study on Friday and has until the end of August to review the project and file a decision, the Fairbanks Daily News-Miner (http://is.gd/hPyn7K ) said Monday.
