The Army has finished an environmental study on the proposed construction of a live-fire training facility at Poha­ku­loa Training Area.

The U.S. Army Garrison Hawaii study published Friday says soldiers would use the Infantry Platoon Battle Course to practice conducting raids, ambushes, reconnaissance and other work.

The Big Island facility would ease a shortage of live-fire training locations for Hawaii-based units.

But the environmental study indicated construction could significantly affect cultural resources. In particular, it says human remains were discovered in a lava tube at one of two construction sites considered.

The Army will decide what action to take after a 30-day public review period is finished in late May.
