July 19th, 2010 - The pre grading work for the beanie cap installation has commenced. The installation of the beanie cap will start on July 26th and will be completed by the end of August.

April 14th, 2010 – The candlestick flare will be down periodically due to the commissioning of the gas plant engines.

April 12th 2010 – We will be re-drilling a pump well onsite as per our regular system maintenance.

January 29, 2010 - Due to the severe thaw and freeze cycle over the last week, we have postponed the drilling of 3 gas wells on the East slope to replace temporary wells until further notice. Thank you in advance for your cooperation.

January 26, 2010 - We experienced odours last week. Last Friday, a leachate dewatering manhole on the south slope and 2 temporary LFG wells were installed on the NW and SW slopes.

The main source was the dewatering manhole on the south slope. The manhole discharges into a leachate collector cleanout manhole. The cleanout manhole LFG quality varies and the extracted flow was reduced as per WM guidelines.

The issue is that the flow of LFG increased in the manhole causing LFG to vent for the leachate dewatering manhole through the dewatering system. This manhole is now maintained under vacuum and has resolved the odours on the south slope.

We also have to drill 2 new wells on the NW slope to stop the odour in that zone as this is now the main source of LFG. We now have odours on the NW slope but get enough dilution to a point where we don't smell odour offsite.

Odour surveys were conducted on Friday and on the weekend and no odours were experienced offsite.

We will also complete a full well performance analysis (circle of influence analysis) and look at water levels in the LFG wells to assess the pump performance.



December 26, 2009 - Due to the power outages and weather conditions the flare system was down for 3 hours between 7:30pm and 10:30pm.

November 16, 2009 - Please note that the enclosed flares will be shut down Wednesday November 18th for regular maintenance. They will be fully operational upon completion of this work. Thank you in advance for your cooperation.

October 23, 2009 - The discharge lines for the purge well system are being replaced around the front of the site. This construction and replacement of lines will enable us to clean and maintain them for the next 25 years. We apologize in advance for the work being completed near the new recycling center. Work is expected to be completed by the end of November.

April 09, 2009 - The flares will shut down at 10:00am. The power outage should last about one hour and is required to update the main electrical panel to connect the new electrical loop around the landfill footprint.

February 12, 2009- Horizontal gas collector trenching will be taking place at the south side base of the landfill commencing on Friday February 13th and continuing on Saturday February 14th. There may be a slight odour impact during the work completion. We apologize in advance for any inconvenience this may cause.

February 03, 2009 - A total of fifteen landfill gas wells will be installed on the northeast corner of the landfill footprint over the next two weeks. Measures will be taken to minimize any odour impact during the construction of the wells. We apologize in advance for any inconvenience this may cause.


August 1, 2008 - Please be advised that due to poor weather conditions, the completion date for the north slope grading will have to be extended from July 31 to August 15, 2008. WM is working on completing this work as early as possible in order to minimize impacts on the community.

July 18, 2008 - Notice of on-going work at Ottawa Waste Management Facility, Carp Road

Please be advised that the potential for some odour on Carp Road may be present from July 21st to July 31st as we remove the old access ramp on the North slope in preparation for final capping. Some waste will be exposed during the process of final grading. Waste that is exposed will be covered immediately upon completion of the work to minimize odour. Waste Management apologizes for any inconvenience this may cause.

July 4, 2008 - A total of approximately 20 landfill gas (LFG) wells will be installed in the next two weeks on the north and south slopes in order to optimize the LFG Collection System. The contractor may work on Saturdays, depending on the weather conditions. Measures will be taken to minimize any odour impact during the construction of the LFG wells and collection system.

The construction of the landfill gas to energy (LFGTE) is progressing well. The concrete foundation for the facility should be completed in next week.

June 25, 2008 - The flares will be shut down on June 25, 2008 for a period of around 4 to 6 hours.

This shut down is required to conduct maintenance on the blowers and condensate chamber dewatering pumps.

June 17, 2008 - We are conducting scheduled maintenance on the flares Wednesday, June 18, 2008, and the flares should be shut down for about 4-6 hours. This maintenance is required to clean the moisture separator and burners.

Construction on the landfill gas to energy (LFGTE) building has started. The footings for the building foundation were installed last week and the foundation walls will be formed this week. The landscapping work has also started on the berm at the corner of the Highway 417 and Carp Road. Trees and shrubs will also be planted on the berm.

The ambiant air monitoring for the benzene monitoring will start this week. A 24 hour sample will be taken every six days for the next seven weeks to determine the benzene concentration at the facility. This supplemental monitoring plan, which has been approved by the Ministry of the Environment (MOE), is a result of an abnormal reading which occured in November 2007.

May 22, 2008 - A total of 35 landfill gas wells have been installed since April 2008. A total of 10 more wells will be installed over the next a 2 weeks. The facility will have a total of over 135 extraction wells at the end of this project.

A total of 6 isolation valves have been installed on the landfill gas collection system in order to close sections of the system when maintenance is required.

A section of the landfill gas collection system will also be upgraded this week. In order to complete this work, a total of 21 wells will have to be closed on the southeast slope to replace a section of the header pipe. Those wells will be reconnected as soon as possible in order to minimize odours. The collection system udgrade should be completed by the end of May.

May 7, 2008 - The drilling that is currently taking place at the WM Ottawa Landfill is to replace two groundwater monitoring wells as part of an updated Environmental Monitoring Plan. The new wells are being drilled deeper than the originals to ensure the water table is intersected at all times of the year. Two additional gas probes are also being installed at the north end of the air barrier system to improve the landfill gas monitoring capabilities

February 6, 2008 - Waste Management Canada Corporation acknowledges that during the past several weeks that there have been occasions when an increase in the odours from the landfill site have been apparent in parts of the surrounding community despite the ongoing efforts of our company to mitigate the problem.

Year over year we have made significant improvements in our landfill gas collection and destruction ability. The flow of landfill gas at the flare in January 2008 was at 2,325scfm. This is up from 1,400 scfm in January 2007 (a 66% improvement) and 1,075 scfm in January 2006 (a 116% improvement). In spite of this improvement, our progress has reached a plateau over this winter as we are unable to access certain areas of the site for safety considerations.

We believe that we have two problems which are currently contributing to this problem. The first problem is the old road area which only has interim cover on it. The second problem is with 20 older wells on the south slope of the site. These wells were drilled on this side of the site a number of years ago and are too shallow and of too small a diameter. They are not capturing all the gas generated which then leaks out through the cap in this area. The solution is that these wells will need to be refurbished to a larger diameter and deepened in some cases by up to 4 times the current depth.

Once the spring construction season is here we will immediately address these issues by re-drilling the 20 existing landfill gas wells to a greater depth with an increased in the diameter, from 6” to 36” and by completing work on the clay cover on the site including the area of the old road.

Further we are already working on plans to start drilling 20 more new wells to continue to improve the landfill gas collection system. These wells are to be drilled on the flat top of the site where the work can be undertaken safely. This will enhance our landfill gas collection ability and begin the preparation work for the installation of the synthetic cap that we are committed to installing.

We thank you for your patience and want to ensure you that we are working diligently to fix our odour issues.
