Oregon’s Public Utilities & Environmental Committee will meet Monday at 6:40 p.m. at the municipal complex on Seaman Road to discuss concerns about the monitoring wells at Envirosafe Services of Ohio, Inc., a hazardous waste landfill on Otter Creek Road.

Ohio EPA earlier this year issued Notices of Violations to Envirosafe regarding the monitoring wells.

Envirosafe has about 120 wells around the facility to monitor the ground water to detect any release of contaminants from the landfill and older waste areas. Envirosafe samples most of the wells on a semi-annual basis, though sampling frequencies vary.

The Ohio EPA requires documentation of the sampling results as well as the methods to ensure monitoring data is accurate. The agency also takes its own samples on occasion to further validate results.

Between July, 2007 and March, 2008, Ohio EPA expressed concerns about leachate level readings, leachate removal totals and flow meter readings related to the primary and secondary leachate collection systems of Cell M, Envirosafe’s only active waste cell.

Leachate, or liquid, that filters through the landfill, must be removed, tested and managed as hazardous waste.

The secondary leachate collection system (SLCS) serves as an early warning system in case of primary liner system failure, and as a backup to the primary leachate collection system (PLCS). High Density Polyethylene (HDPE) SLCS riser pipes, 12 inches in diameter, run down the side slope of the cell into leachate collection sumps.

The Ohio EPA asked Envirosafe on Feb. 8, 2008 to consult with its engineers, Mannik & Smith Group, to determine the cause of trends in the data from Cell M’s leachate collection system, and to discuss its findings with the agency.

In response, Envirosafe placed a camera down the PLCS risers on March 10. The camera showed the presence of leachate in the primary sump pump and that leachate accumulation on the primary liner was significantly higher than what is allowed.

Joann Schiavone, long-time environmental activist, raised concerns about the monitoring wells at a council meeting last Monday.

City law director Paul Goldberg said the city has already complained to the Ohio EPA about the leachate.

“I can guarantee we’ve already pointed that out on a number of occasions,” he said.

“On deaf ears,” said Schiavone.

“Unfortunately, you’re right,” said Goldberg.

“That needs to stop,” said Schiavone.

 “You need to find out if contaminants are leaking into the right-of-way, and finding their way to Maumee Bay and Lake Erie,” said Schiavone. “The buildup of leachate in the cells and waterline trenches are violations of the permit. The buildup in Cell M compromises its integrity. The only way to find out if Cell M is leaking, and if contaminants are going off-site, is with monitoring wells.”
