Ontario Co. Landfill
- Posted: October 16, 2015
Despite having just added a new main gas header line, we are once again planning to undertake an additional expansion of the landfill gas collection system beginning in mid November (which has been approved by the NYSDEC). We are planning to add 11 new vertical gas wells which will be tied into the existing gas collection system and should be on line by mid December.
The north and a portion of the western side slopes have recently been seeded as we prepare for winter and we are continuing to clean out the two main stormwater retention ponds.
A majority of the final cover system has now been removed.
We have been filling the lower northern slope for the past few weeks where the final cover system was recently removed. As part of this effort we will be installing horizontal gas collectors as the waste progression proceeds in this general area over the next several weeks. In addition, we are awaiting NYDEC approval for the installation of a new 10" landfill gas header line along the upper back portion of the landfill to provide additional vacuum to gas wells that were installed earlier this year. We are also looking into the installation of 10 - 12 new vertical gas wells which pending NYSDEC approval we hope to install this Fall. Lastly, we are planning (also pending DEC approval) to install ~ 5 acres of temporary exposed geomembrane along a portion of the the back western side of the facility (expanding the existing geomembrane cap).
We are continuing to successfully remove the final cover components along the eastern, northern and western edges of the first cells within the Phase III landfill. As part of this effort we are also continuing to relocate amd expand the landfill gas collection lines and/or we have temporarily shut off some gas wells (as allowed under the air permit). Vacuum will be safely restored to these wells following landfilling activities within these areas.
In addition to the cover removal activities we are also in the process of installing a new haul road along the back eastern slope.
Lastly, starting early next week we will be having a contractor continue with electric utility line relocation along the frontage of the facility near gas to energy facilities.
We have been experiencing a significant amount of rain over the past several days. The rain has hampered at times the placement of cover soils. In addition, our current active filling area is located along the upper slope and furthest eastern edge of the landfill. We are working diligently to work through the inclement weather. We are also in the process of installing a new haul road along a section of the eastern slope as a means to facilitate future disposal operations within the western expansion area.
The recently installed vertical gas wells have all been connected to the gas collection system. We are now in the process of covering the
slopes that were impacted from the lateral and header line installations.
We are doing some testing of the 4 gas flares this afternoon and the power plants have temporarily been taken off line in order for us
to complete these tests. We anticiapte the plants will only be off line for 60-75 mins this afternoon.
