Hoping to quell public concerns about handling landfill leachate at Endicott's Huron Campus, i3 Electronics officials met Wednesday with local politicians to outline the mechanics of its waste treatment facility.
Despite numerous concerns from Endicott area residents about testing for metals and other hazardous substances treated at the plant and discharged as effluent into the Susquehanna River, i3 officials said Wednesday the plant's operations continue to follow state environmental regulations in successfully treating leachate. On Aug. 4, the state Department of Environmental Conservation sent i3 a letter confirming the facility complies with State Pollutant Discharge Elimination System (SPDES) program permit limits.
After meeting Wednesday with local politicians — Broome County Executive Debbie Preston, Sen. Fred Akshar, Endicott Mayor John Bertoni and Union Town Supervisor Rose Sotak — Paul Speranza, i3 director of environmental services, said the company is "doing everything that can be done to properly treat the wastes that we have coming into the facility."
"The (SPDES) permit is important to us," he said. "This facility is able to do treatment to a higher level than some of the other plants in the county and elsewhere."



Since 2011, the Endicott facility has been treating leachate, which is groundwater collected at a municipal landfill.

Coalition have particular concerns about waste leachate shipped from Seneca Meadows — a landfill that once accepted waste from Marcellus Shale drilling operations in Pennsylvania.

According to i3 officials, some 80 million gallons of leachate have since been treated at the Endicott facility — 72 percent of it coming from Broome County and 28 percent from Seneca Meadows. Leachate accounts for 10 percent of the total plant flow, officials say.



The topic of treating leachate is especially sensitive given the history of the Huron Campus, which is listed on the state's hazardous site registry because of chronic pollution from TCE and other industrial solvents from the pre-regulatory era. Although progress has been made with cleanup operations spanning more than 35 years, high concentrations of TCE remain under some buildings.

"We test for a lot of things we don't even use, things like TCE ... we don't detect — they're not there," Speranza said Wednesday. "If we detect anything that's not supposed to be there, we talk to the DEC and come up with an action plan."

In February, 2013, landfill leachate was spilled at the Clark Street plant, according to DEC records.
