Ontario Co. Landfill
- Posted: August 5, 2016
Construction of the new landfill cells as part of the wrap around expansion is continuing on schedule. The new leachate lagoons and interim cell (#9) are now fully constructed. Most recently the new pump station was successfully tested by our external engineers as required. Certification reports have been submitted to the NYSDEC for their review which following Department approval, the lagoons will be placed into operation. All waste relocation activities as part of the construction of the expansion cell #8 have been completed and once the new lagoons are placed on line, the existing lagoon will be taken out of service and removed as part of the construction work necessary to finalize completion of cell #8. Waste placement currently continues on top of the landfill which upon approval from the DEC will be redirected to the front of the facility into cell #9 for approximately 3-4 months prior to moving into cell #9 pending DEC approval of that cell in the future.
Efforts are continuing to be made to expand the existing landfill gas collection system including installation of new horizontal gas collectors yet this year and new vertical wells in early 2017.
Additional efforts are currently underway to provide additional intermediate cover and erosion control measures on the eastern slopes of the landfill.
The power plants were temporarily taken off line in order to complete additional gas collection system tie ins that are now required as a result of the realignment and upgrades to the system.
The landfill cell construction and leachate infrastruture improvements projects are now well under way including the waste relocation activities. The relocation of the landfill collection system header and new condensate knock out installation are now complete.
As part of the daily operations we have been continuing to regularly water the access and haul roads at the facility. We are proactively working on measures for controlling dust.
The power plants will be taken off line on Wedsnesday again to allow connection of the new 18" gas header lines on both the east and west sides of the facility. As in the past, the flares will be operated while the plants are off line.
As previously reported, as part of the upcoming cell construction activities we will be relocating (older) waste in order to remove two manholes. This activity has been delayed pending final approval from the NYSDEC for this phase of the project.
Aside from the delay associated with the waste relocation, the construction work is on schedule.
The power plants have been taken off line today due to utility maintenance by NYSEG. We have been running the flares and expect the plant to be back on line later this evening. We anticipate that the plants will be taken off line again later this week for a short time as part of the new landfill cell construction activities (pending approval of that phase of the project by the NYSDEC).
Our prime contractor mobilized their equipment and started the leachate mangement infrastructure improvements project which has been approved by the NYSDEC. In addition our landfill gas contractor has been continuing to proceed with installation of new lines that will be tied to the recently installed vertical gas wells (8) as well as realignment of the existing landfill gas collection header along the northern perimeter of the site.
As part of the upcoming cell construction activities we will be relocating (older) waste in order to remove two manhole locations as part of an upgrade to a vertical sideriser leachate removal system. We anticipate that the waste relocation will start during the second week of April. Based upon our past successful experiences moving similar waste materials we will be prepared to mitage odors as best as possible should they arise. The waste will be covered at the end of each day as required by the facility permit.
