Ontario Co. Landfill
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.
Installation of the 8 new vertical gas wells will be completed today. On March 8th we have a contractor starting who will be relocating a portion of the exterior landfill gas collection header in preparation for the upcoming landfill cell construction. Following realignment of the header line, the 8 new gas wells will be connected to the existing gas collection system.
We have started to import clay for the upcoming construction project and we will soon be taking delivery of various materials that will be utilized during the construction including geomembrane liner and textile rolls and precast concrete manholes. We anticipate that the construction activities will commense in late March or early April depending on the weather.
The two new landfill gas flares that are referenced in the new air permit will be arriving in early April and will installed shortly thereafter. All landfill gas continues to be beneficially utilized in the on site landfill gas to energy facility.
We are continuing to expand the landfill gas collection system including the replacement of gas wells that were abandoned as part of the recent final cover removal project (both approved by the NYSDEC). Pending additional approval from the DEC, we are proposing to install eight (8) new vertical wells along the upper north secton of the landfill. In addition to these upgrades, we are also planning to relocate the main gas header lines coming into the landfill gas to energy plants which is needed as part of the upcoming landfill expansion construction efforts. We will also be installing two (2) new gas flares in the coming weeks as provided in the new air permit for the facility.
