No waterways were contaminated by Monday’s fire and cleanup at a Jamestown-area munitions plant, according to the state Department of Environmental Protection.

But the wastes that contaminated the soil in the rubble from the fire are hazardous and will require a specialized cleanup, said DEP spokesman John Poister.

Combined Systems Inc. will pay for the cleanup by a specialized firm, and DEP will oversee it, Poister said.

Among the contaminants DEP is looking to have cleaned up are the remnants of “CSI-branded” tear gas that’s a widely distributed crowd suppressant, used in the wake of the Arab Spring in north Africa and the Middle East. (CSI tear gas canisters were even spotted in the Monday-night episode of the television show “Hawaii Five-O.”)

Also found at the site off state Route 58 in Greene Township were acetone, saltpeter (potassium nitrate) and guncotton (nitrocellulose), used in blasting caps.  

“That sounds powerful,” Poister said of the nitrocellulose.

The noontime fire left the building, one of several on the site, in ruins.

The cause wasn’t known but wasn’t suspicious and likely not linked to last week’s cyber attack that shut down the company’s website or the protest in January, according to Richard Edge, chief operating officer of the company.

The fire halted production, but “the main thing is no one was hurt,” Edge said.

The fire was the second at CSI in three months; the first was in a different building on Nov. 15.

Since then, the company bought new fire-suppression equipment and modified procedures, Edge said.
