PERC test reveals rifle range materials usable for energy

Warren — The cleanup of the former Warren rifle range is taking on a new twist.

According to David Madore, communications director for the Department of Environmental Protection, Penobscot Energy Recovery Co. has completed testing of the fiber material, and found it to be usable.

PERC removed 100 tons of the carpet material from the site and transported it to their new terminator for testing in August.

Town Manager Bill Lawrence reported to the Board of Selectmen that he was informed the material passed the test to see if it was a viable source of energy.

In June, Lawrence confirmed the material was no longer being trucked to Triumvirate Environmental Inc.'s site in Pennsylvania.

The DEP has approximately $375,000 set aside for the remediation of the site, according to Bill Longfellow of DEP.

The property in question, located on Route 90, housed more than 27,000 tons of polyester fiber material originally brought in to create a berm to absorb bullets and the sound of gunfire at the proposed rifle range.

The DEP had contracted with Triumvirate -- at no cost to the town -- to truck the scrap material to its site in Pennsylvania, where it planned to use it in making composites for manufacturing other things.

Per contract stipulations, Triumvirate began work at the site more than two years ago. Forty-two tons of the scrap material was to be removed weekly to start, then, in October 2015, the weekly amount was to increase to 210 tons. The initial expected completion date for the project was late 2016 or early 2017.

"We are currently waiting for an estimate from PERC as to the cost to DEP," Madore said in an email Oct. 4.
