Site compartmentalisation Process
Following the process outlined above each of the compartments was assigned a ‘Type’. For each of these, the material or
range of materials was assigned (since different materials will have a different potential environmental impact) and the
location on site was reviewed to assess the need to split the compartments. To enable the process to be visually inspected a
Geographic Information System (GIS) was used to collate the results from the process.
Figure 3
illustrates the result from
the compartment derivation process for the case study site.
