Landfill Site Service Area Amendment

In 2016, the City of London received approval from the Ministry of the Environment and Climate Change (MOECC) to accept waste from five locations that were outside of the W12A Landfill’s approved service area.  These locations and the types of waste to be accepted are:

  1. Lake Huron water treatment plant (water treatment plant process residuals),
  2. Elgin Area water treatment plant (water treatment plant process residuals),
  3. TRY Recycling’s Clarke Road facility (construction and demolition (C&D) recycling process residuals and residential garbage),
  4. Thames Centre (curbside collected municipal waste without shipping a corresponding amount of waste to Thames Centre), and
  5. Elgin County (Municipal Hazardous and Special Waste (MHSW)).

* see a list of Frequently Asked Questions below for further detail.

Previously, the W12A Landfill Site was approved by the Ministry of the Environment and Climate Change (MOECC) to accept solid, non-hazardous waste generated within the boundaries of the City of London for disposal, and Municipal Hazardous and Special Waste (MHSW) generated from London and Middlesex County at the Household Special Waste (HSW) Depot located at the W12A Landfill Site for transfer to appropriate recycling / processing sites.  The W12A Landfill was also approved to accept residential waste from Thames Centre in the winter months when their landfill is closed, provided a corresponding amount of waste from London is shipped to Thames Centre in the summer months when their landfill is open.

Changing the W12A Landfill's service area required approval under the Environmental Assessment Act (by undertaking an Environmental Screening Process) and the Environmental Protection Act (by amending the Landfill's Environmental Compliance Approval).  This webpage provides information about the City's Environmental Screening Process.

  • Why was the City proposing to increase the service area of the W12A Landfill Site to to include additional specific locations??

    It was proposed to accept materials from these new locations because:


    • Lower costs can be achieved – The cost for London to operate the landfill is lowered because of “economies of scale”. Tipping fees for those using the W12A Landfill may be lower than alternative disposal options.
    • London waste – Over 80% of the waste from the new locations is generated as a result of providing services to residents of London (e.g., clean drinking water, recycling location for construction and demolition waste, drop off depot for London wastes).
    • Regional coordination – London and several nearby municipalities already work together on recycling programs.  The County of Middlesex residents already have access to the City of London Household Special Waste (HSW) Depot.  Accepting Municipal Hazardous and Special Waste (MHSW) from Eglin County and municipally collected garbage from Thames Centre is a continuation of the regional approach to finding solutions for managing waste.  For example, accepting MHSW from Elgin County will provide a convenient location for its residents to take their MHSW which should reduce the amount of material ending up in the garbage.
  • What is water intake screened process residuals?

    This waste is generated when turbid (e.g., muddy) water from the lakes is pumped into the water treatment plants and the suspended solids causing the turbidity are screened out (Figure 1). The process residual is soil like in nature (i.e., suspended sediment from turbid lake water).  Whenever possible, this non-hazardous soil like material will be used as cover material to cover garbage at the landfill.


    Figure 1

  • What are construction and demolition residuals?

    Construction and demolition (C&D) residuals are the materials left over from the recycling process.  Approximately 80% of the C&D material processed at the TRY Recycling facility on Clarke Road (in Middlesex Centre, on the border of London) is recycled while 20% becomes process residuals.  A majority (80% to 90%) of the C&D material processed at the TRY recycling facility comes from sources within the boundaries of London.

    The process residual generated is solid non-hazardous waste consisting of materials like film plastic, insulation, flat roofing, bulky items like mattresses and couches and other materials that cannot be recycled (see Figure 2).

  • What is Municipal Hazardous & Special Waste (MHSW)?

    MHSW consists of paint, batteries, fluorescent tubes/bulbs, solvents, pesticides, fertilizers and other household hazardous and special wastes.  None of these wastes will be buried at the W12A landfill.  The W12A Landfill Site has a HSW Depot where all MHSW waste accepted is transferred to appropriate recycling/processing facilities for management. 

  • How much more waste will be coming to the W12A Landfill Site?

    The increase in waste coming to the landfill if the proposed service area changes are approved will be approximately 41,000 tonnes per year (20,000 tonnes of which is water intake screened process residuals that can be used as daily cover and therefore not consume any capacity designated for managing waste). 

  • How does this compare to the waste already coming to the W12A Landfill Site?

    In 2014, the total waste received at the W12A Landfill was 223,000 tonnes.  In the first six months of 2015 approximately 97,000 tonnes was received due to a reduction in business waste. 


    The total waste coming to the landfill based on 2015 estimates if the proposed service area changes are approved will be approximately 240,000 tonnes per year.


    It should be noted that 240,000 tonnes per year is comparable to the average annual amount received over the last ten years as the amount of waste coming to the landfill has been decreasing in recent years.  The most waste received at the landfill in any one year was 310,000 tonnes in 1987.

  • How many vehicles / trucks will be coming to the Landfill?

    There are approximately 80,000 vehicles per year going to the landfill and adjacent Material Recovery Facility (i.e., recycling centre).  It is estimated there will be an additional 2,600 vehicles per year if the service area is enlarged to include the five new locations.  This is less than a 3 percent increase over current conditions.



  • What will the additional waste do to the life of the landfill?

    Under current conditions, the landfill has approximately 10 years of capacity remaining.  If the increase in the service area is approved, the additional waste will reduce the life of the landfill by approximately one year.
