DOYLINE, La. (AP) — Authorities say it could take up to three weeks to finish moving military propellant into storage at an explosives recycling company that caused the evacuation of a Louisianatown.

The town of Doyline was evacuated earlier this month after authorities said they found 6 million pounds of the material improperly stored at Explo Systems Inc.

Explo contracts with the military to demilitarize explosives and other materials.

The company rents space at a National Guard base in north Louisiana.

The material found improperly stored on the base is called M6 and is used as a propellant for artillery rounds.

Louisiana State Police spokesman Matt Harris says Wednesday that crews have moved 4.6 million pounds of product into proper storage sites.

A criminal investigation is ongoing.
