A landfill located in the town of Carroll may be seeing a drastic reduction in its size, beginning as early as next March.
The DEC held a public information session Wednesday at the Town of Carroll Highway Department to discuss the plan to consolidate the landfill located just north of Ivory Road in Carroll.
The landfill, which is broken up into two cells, east and west, covers roughly 25 acres of land currently. After the proposed consolidation, it would be reduced to approximately 15 acres of land, according to Vivek Nattanmai of the DEC.
"We don't have exact numbers in regard to the size of each cell, but we do have the size of the total landfill area, and the east cell is roughly 10 acres," said Nattanmai. "That 10 acres will be free of any landfill material after consolidation, so it can be used in the future for any unrestricted uses. Since people complain that they have lost hunting ground, we'll be planting trees after we remove the waste, too."
After a feasibility study was completed in February, it was determined that consolidating the two landfill cells would be the most appropriate action for a number of reasons. The consolidation would, first and foremost, result in a reduction of the landfill's footprint. Second, fill from the east cell could be used to cover the west cell, reducing the amount of clean soil that would be needed to establish the required contour for the west cell. This method would also reduce the estimated maintenance cost for the landfill, while also being approximately $2 million less expensive that covering both cells as they sit currently.
"If we consolidate the two cells, we'll be taking the material from the east cell and using it as part of the new cover for the west," said Nattanmai. "It won't be quite the elevation and contour that we're looking for, but it will reduce the cost and make it easier in the future."
According to Nattanmai, the DEC began testing samples from the soil near the landfill in 2004 after a contaminated groundwater source was located.
"We haven't found any hazardous materials in the landfill, so there must have been something dumped there many years ago that caused the contamination," said Nattanmai. "That is why we will be able to use just a normal soil cover for the landfill after the consolidation. If we had found contaminants in the landfill currently, we would have had to use a cover with a liner and several other components, which is much more expensive. We don't need to do that in this situation, though."
When the contaminated groundwater was identified, tainted by vinyl chloride, the county shut down pumping well No. 5. The DEC was brought in on the project however, and installed a water treatment system.
"(The town of Carroll) didn't want to give up on that well because it's a very productive well," said Nattanmai. "We just finished the installation of the treatment system, and we're running demonstrations of it right now, so in a month or so it will actually go online and start pumping back into the distribution system."
The water treatment plant will be capable of bringing the contaminated groundwater back to a drinking water standard that will meet New York sanitary code requirements, and after it's treated it can be sent down to the distribution system to be used for the town's water system. This treatment system is also one of the first projects in the state of its kind.
The next steps in the process will include designing the landfill cover, bidding of the job, and the actual construction and consolidation, which is estimated to begin in March 2014.
