"They certainly didn't want it to stop coming in. If they quit taking it, they lose that income," said Sheriff Gary Sexton in Webster Parish, where the facility is located on a Louisiana National Guard base called Camp Minden. Sexton has been involved since the evacuation and early stages of the investigation.

Abney said "it was the understanding" of Army representatives that Explo was going to sell M6 to Kentucky Powder Company â¿¿ an explosives company with offices in Lexington and Mount Vernon in Kentucky â¿¿ to be used in the production of blasting slurry for coal mines.

Explo sold Kentucky Powder 2.16 million pounds of M6 in July 2011 and its plan said it had "supply agreements with two major mining slurry manufacturers," according to documents obtained by AP.

R. Edward McGhee is president of Kentucky Powder Company, according to filings with the Kentucky Secretary of State's office. Business filings in Louisiana list him as a director of Explo Systems.

McGhee said in a telephone interview that Kentucky Powder hadn't bought M6 from Explo in more than a year because demand was down. He said the company doesn't store explosives for other companies.

McGhee said he spoke to Explo officials who told him the plan mistakenly said the company had 70 million pounds of storage and should have said 7 million. McGhee did not mention being listed as a director of Explo Systems and hasn't responded to subsequent telephone calls.

The plan said 70 million pounds at least three times.

Linda Potter, a spokeswoman with the Kentucky Department for Natural Resources, said neither company has permits to store Explo Systems' propellant.

"To store explosives or lease space for Explo, both Kentucky Powder and Explo Systems would need to obtain the appropriate permit from the Explosives and Blasting Division. Neither company currently holds this permit, nor did they in 2010," Potter said.
