The City encourages any questions or comments you have about this project. If you would like to arrange a tour of the landfill site, or a one-on-one meeting with landfill staff please contact us.
The Landfill Re-engineering Project is partially funded by the federal Gas Tax Fund. The City receives over $7.8 million on an annual basis, providing a stable, predictable and long-term source of funding for environmentally sustainable municipal infrastructure.
In 2008, the City began upgrading the City’s landfill to meet engineering and environmental standards. This re-engineering consists of 3 phases, during which approximately 60% of the existing landfill will be reclaimed and lined.
In summer 2014, the City entered the final stage of Phase 3 of the project, which is scheduled to be completed by the end of 2015. The project is expected to extend the life of the landfill by 18 years (until 2035).
Project activities include digging up the old garbage and screening it to separate sand (daily cover material) from the garbage. This sand is re-used for current daily cover, saving valuable landfill space. Some materials (for example metal and concrete) are removed and re-used or recycled.
In 2011, a Landfill Gas Collection System and Flare were installed. This flare burns methane gas released from the garbage, reducing greenhouse gas emissions and odours. Expansion of the gas collection system is ongoing as new landfill cells are constructed and filled.
A cell is an area within the landfill that is designed to contain garbage disposed at the site. New cells are constructed and lined with plastic (high density polyethylene) and geosynthetic clay liners that prevent contaminated water, or leachate, from entering into groundwater below the landfill. The old garbage is recompacted along with incoming garbage into the new lined cells.
As of Summer 2014, five new cells had been constructed and approximately 1,400,000 cubic metres of garbage has been processed. Phase 3 activities will include the excavation and screening of garbage and the installation of liners and leachate collection systems in the last cell. The remaining garbage (approximately 260,000 cubic metres) will be processed and placed into the new cells by the end of 2015. Landfilling in new cells will include the progressive installation of landfill gas collection system piping.
Residents have indicated that their main concerns related to the project are odours, air quality and health effects. In 2010, the City completed an Air Quality and Health Assessment to evaluate what compounds are released into the air from the landfill and whether they could affect people’s health. The study confirmed that the gases from the landfill do not pose a health concern to the public.
In spring 2014, the City initiated a followup study to monitor current air quality conditions. The samples collected at the boundary of the landfill were generally lower than the ones collected in 2010. The sampling equipment did not detect typical odour causing compounds that come from garbage, such as sulphur, ethanol and ammonia. People can however smell odours at lower levels that do not relate directly to air quality standards.
During the Landfill Re-engineering Project activities, areas neighbouring the landfill are routinely monitored for odour by City employees. We encourage you to call City staff at 705-739-4220 x4516 if you have any concerns about odours resulting from the project.
When significant odours are detected, work at the landfill is immediately adjusted or stopped. Staff work within small areas of exposed waste to minimize odours. If needed, Odour Suppressant Foam and Odour Suppressant Misters are used to control odours during the work. Odour control mechanisms have also been investigated to determine their health effects, and are considered safe for use at the landfill.
The Barrie Landfill is being “re-engineered”, meaning that garbage in the landfill is excavated and screened. Following construction of an engineered liner and leachate collection system under each cell, the garbage is re-compacted along with incoming waste from City collection. The re-engineering project involves reclamation of waste from the western two-thirds of the surface area of the Landfill and construction of new lined cells. The re-engineering of the landfill site is required for the long-term protection of groundwater and surface water, in line with current engineering and environmental standards. The new lined cells are designed to collect leachate from the landfill which will be treated at the City wastewater plant. Controlling landfill leachate at the source is the most effective method of protecting water quality.
A landfill gas collection system installed in 2011 burns methane released from the garbage, which reduces greenhouse gas emissions as well as odours. Expansion of the gas collection system is ongoing as new landfill cells are constructed and filled. The re-engineering will also reduce the overall height of the landfill.
The Landfill Re-engineering Project was commenced and planned to be completed in three phases between 2008 and 2015. The first phase was completed in 2009 and involved the southernmost part of the landfill; the second phase was completed in February 2013 within the central area. The third phase of the Project in the northernmost landfill cells began in March 2013 and is expected to be completed by December 2015.
To date, five new cells have been constructed and about 1,400,000 cubic metres of garbage has been processed. Construction of the landfill gas flaring plant and upgrading of capping and stormwater controls in the area of Cell 1 were also undertaken. Ongoing activities during Phase 3 will include the excavation and screening of waste and the installation of liners and leachate collection systems in the northernmost cell, which will be used to landfill garbage after 2015. The remaining garbage (about 260,000 cubic metres) will be excavated and screened over the next year. Landfill gas collection system piping is extended as garbage is placed in the new cells.
The entire Project cannot be completed in the winter months because the liners need to be installed during non-freezing conditions. In addition, the reclamation and cell construction must be scheduled to make sure there is enough capacity in the new cells to continue to manage incoming City garbage. Project operations and scheduling in 2013 and 2014 have been adjusted to stop garbage excavation and screening operations in the summer months, in order to minimize odour impacts on residents.
Following completion of the project in 2015, the landfill is projected to have enough capacity for City garbage for another 18 years (until about 2035). The sustainable waste strategy undertaken by the City to manage City waste into the future will maximize landfill lifespan.
The landfill gas collection system is a system of pipes and a flare designed to collect and burn landfill gases that are released as garbage decomposes. The flaring of the gas helps to reduce greenhouse gas emissions and odours. The system has been operational since 2011 and new collection pipes are installed as re-engineering progresses.
There are no plans to change the current zoning (e.g., Environmental Protection lands).
New cells that are being constructed are lined with plastic (high density polyethylene) and manufactured clay liners that prevent contaminated water, or leachate, from entering into the groundwater below the landfill.
The cost of the liners varies depending on the amount and design, but is in the order of $25 to $30 per square metre installed.
The City of Barrie Police patrols the area and will respond to specific calls regarding dirt bikes and all-terrain vehicles.
The City completed an Air Quality and Health Assessment in 2010 to analyze the air in the area of the landfill. The results of the study confirmed the compounds in gases from the landfill do not pose a health concern to the public. A follow-up study was initiated in the spring of 2014 and confirmed the concentration of compounds were equal to or less than those found in 2010. Additional air quality sampling will be completed in the fall of 2014.
During times when garbage is being excavated, the site and surrounding neighbourhood are monitored by City staff for early detection of off-site impacts such odours. If required, on-site activities are modified to limit odours, including modification of excavation, deploying odour mitigation measures, or if necessary, stopping all activities to ensure the odours are properly controlled. Other activities including regular waste placement and composting are similarly managed to minimize odour generation.
Measures used to reduce odours from the reclamation project include minimizing working areas to reduce exposed waste, placing cover material close to work areas so waste can be covered quickly when work is done, and use of odour suppressant misters and foam. The odour suppressants contain natural ingredients and are safe for humans and the environment. Daily work activities are planned based on weather and wind conditions to minimize odour effects on residents. In order to proactively control odours, garbage excavation and screening was stopped during the summer months of 2013 and 2014 when the potential for odours is the greatest and people may be at home more often.
Residents are encouraged to report any odours to City Staff (705-739-4220 ext. 4516).
The odours related to reclamation operations are largely caused by sulphur containing compounds in the gas generated during the decomposition of the garbage. This gas is released when the cover and garbage are excavated for processing. Odours are also caused by incoming garbage from City collection and by landfill gas releases in the completed areas of the landfill. Landfill gas is typically about 60% methane and 40% carbon dioxide with less than 1% other compounds (for example sulphur compounds, ethanol and ammonia).
The landfill gas collection system collects gases that are released as garbage decomposes which are conveyed to the flare and burned, helping to reduce greenhouse gas emissions and odours.
The presence of odour does not necessarily indicate the presence of hazardous compounds. The human nose can detect sulphur compounds, ethanol and ammonia at very low concentrations, well below the concentrations established by environmental and health regulations. The Air Quality and Human Health Assessment completed in 2010 and 2014 indicated there was no risk to human health from the air quality measured during reclamation operations, even though the compounds causing odour were present.
The City will complete another round of air quality sampling this fall, including evening sampling, to respond to residents’ concerns.
The City is completing another round of air quality sampling this fall, including evening sampling, to respond to residents’ concerns. An air quality report will be available after the air quality sampling is completed.
The odour suppressant used is AirSolutonTM 9309 Odour Counteractant. This suppressant is a blend of essential oils and odourous organic compounds found in plants. The odour control products are considered safe for use on the basis that they have been applied according to manufacturer’s recommendations and the key ingredients are approved for use in cosmetic and food products. The odour control products have been applied to the airflow in many waste, commercial, industrial and wastewater settings.
Stormwater runoff from the completed (final covered) areas of the landfill is directed to stormwater control ponds and largely infiltrates to the ground. All stormwater potentially in contact with waste is contained within the landfill cells and is discharged to the City Wastewater Treatment Facility. During larger storms, runoff from these areas is directed to Dyments Creek. The landfill is situated within the drainage watershed for Dyments Creek, which ultimately drains to Lake Simcoe.
The infiltration ponds and drainage channels are designed to promote infiltration of stormwater into the ground and prevent discharge off the site including and up to a 1 in 100-year storm event. In larger unusual events, any runoff will be directed in a controlled manner to the roadway and ultimately Dyments Creek. Silt runoff will be managed with silt fencing and other control measures in the interim period until the stormwater ponds are operational.
As the landfill is progressively completed and capped, the clean runoff is required to be controlled. Under normal conditions, all stormwater is managed on-site and there is no off-site discharge. Six new stormwater ponds and associated channels have been designed in the western part of the landfill as part of the reclamation project. This stormwater management system is designed to control runoff from major storm events that would otherwise result in discharge to Edgehill Drive and Dyments Creek.
The Stormwater Management Plan has been prepared to manage surface water run-off from the landfill, which is a regulatory requirement by the Ontario Ministry of Environment and Climate Change. The stormwater management ponds will control surface runoff and promote infiltration of stormwater into the ground. These ponds are strategically located in close proximity to the landfill to manage runoff within the site. The stormwater management system has been designed to infiltrate storms as large as a 1 in 100 year event, as required by the current regulations. The system is also designed to manage larger flows in unusual storm events.
This stormwater management system is designed to control runoff from major storm events that would otherwise result in discharge to Edgehill Drive and Dyments Creek. The majority of infiltration ponds will be located further north on site away from the residences on Edgehill Drive. A finishing pond will be located downstream where the clearing is located west of the north-south easement to Edgehill Drive. The final pond will have the capacity to control a major storm event that is not infiltrated in the upstream ponds.
The pond locations were selected to effectively manage stormwater runoff as close to the landfill as possible and are sized to minimize tree loss and impacts to off-site groundwater levels. The locations of the ponds were designed based on the final contours of the landfill. The ponds are also designed to infiltrate as much water as possible local to the landfill. Under high stormwater flow conditions the surface water will progressively spill over into the lower ponds in the system, ending at Pond 6. In a very large storm, some surface water may temporarily discharge to Edgehill Drive.
Yes. The Stormwater Management Plan was designed to accommodate surface water run-off from the final build out of the Landfill and promote infiltration of stormwater into the ground while the landfill is operational.
Consultation with regulatory agencies is recommended under the Stormwater Management Planning and Design Manual (MOE, 2003) to determine existing areas of environmental significance. These agencies include the City of Barrie, Ministry of the Environment and Climate Change and the Lake Simcoe Region Conservation Authority.
The infiltration ponds were designed to minimize tree loss and visual impact to residents. Trees and shrubs will be planted along the edges of the shallow ponds. The southernmost infiltration pond may be partly visible in some locations but it is relatively shallow and will appear as a grassy depression.
Trees and shrubs will be planted along the edges of the ponds to minimize tree loss and visual impact to neighbours and land users. Pond design includes the use of gentle slopes which eliminates the need for fences.
The ponds will only contain water during and shortly after major storm events, and therefore the ponds will rarely contain standing water.
A natural environment study was completed as part of the preparation of the Stormwater Management Plan. The studies are summarized in the Environmental Impact Statement report and confirmed no significant impacts resulting from the planned stormwater ponds. No occurrence of potential species at risk was recorded in the study area.
The fencing of the site is a regulatory requirement, as well as a health and safety measure to control access to the active areas of the landfill. Following landfill closure, the areas requiring fencing will be re-assessed.
In 2014, City Council approved an Urban Forest Strategy for Barrie which outlines 26 specific objectives to be completed leading to the development of an Urban Forest Management Plan commencing in 2017. The Forest Management Plan will include individual forest succession plans for city owned forest in parks and EP areas. The forested areas around the landfill will be inventoried and a long term plan developed to ensure its sustainability.
