LANDFILL MANAGEMENT

Landfill sites are licensed by the Environmental Protection Agency (EPA) and inspected regularly to ensure that activities on site are compliant with licence conditions. Results of these inspections are made available to members of the public by contacting EPA headquarters.

Landfill operators are also required to monitor a number of parameters relating to the operation of the site such as landfill gas and leachate control systems and groundwater. These are reviewed at site inspections.

Waste that is collected for disposal at landfills may be taken directly to a landfill or may betransported to a transfer station for baling or repackaging with other waste into large vehicles before eventually being taken for disposal. Once at the landfill the vehicles are usually weighed and the weight and type of waste in each load is noted. This information helps to ensure effective management of the site and to minimise the potential for environmental pollution. After weighing, the vehicles are emptied into the area of the landfill that is being filled and all vehicle wheels are washed when leaving the site. Material is placed in a modern landfill on a cell by cell basis, as this makes it easier to control odours, litter and pests. At the end of each day, the deposited waste is covered with a material such as soil to limit the potential for pest infestation and littering of the surrounding areas. Other pest control measures can include keeping birds-of-prey on site to control birds and rodents.
