Landfill sites are closely regulated and there is an onus on site owners to manage sites and their associated environmental liabilities for as long as they continue to pose a risk to the environment. However, over time there is a gradual decrease in the elevated concentrations of potential contaminants present in landfills, and there comes a time when they no longer pose a risk to environmental receptors. At this time, the landfill licence or permit can be surrendered and the site is said to be completed.

In order to surrender a licence or permit, the site owner must demonstrate that the risk from the site is no worse than it was when the environmental permit was issued. This is achieved via the production of a landfill completion report.

ESI has assisted a number of operators to achieve landfill completion with the result that these sites are no longer a liability and can be developed for subsequent use.

Landfill completion reports require an assessment of the current condition of the landfill and its surroundings. This assessment must be compared with the “baseline” position (i.e. the situation when the permit or licence was issued).

ESI can help clients reach completion by providing its own specialist expertise for soil and groundwater contamination issues, and that of its associates for stability and landfill gas issues:

Services: - Landfill Completion Reporting

A review of environmental monitoring data collected for site assessment purposes
Assessment of the data and of relevant monitoring and risk assessment reports, to establish long-term changes in:

a) the source term (the landfill mass and the leachate contained therein);
b) the pathways by which contaminants may migrate (including the landfill engineering components) and
c) the environmental receptors that might be impacted by any contamination.

Update, or reconstruction of, the risk assessment(s) if this is required
Review and updating of site stability plans and reports
Concise reporting of:

a) outcomes of environmental data review;
b) long-term trends in contaminant concentrations;
c) changes to pathways and environmental receptors;
d) comparison of the current and baseline situations and
e) summary of any residual risks and recommendations for site completion.

ESI’s considerable experience in soil and groundwater science enables us to tackle and address any issues that may arise at site completion in an innovative and practical manner. Our proven track record and working relationships with regulatory authorities also enables pragmatic discussions and satisfactory solutions to be found.
