Monitoring needs to commence during the construction phase, and continue during the
operational phase.

11.1       Water Quality Monitoring During Construction

          During construction, monthly monitoring for the parameters described in Table 11-1 is
          recommended from sites 7 to 9 (Table 11-2). Additionally, it is recommended that the
          suspended solids concentration of stormwater is measured at sites 10 to 14 during
          stormwater events, with collection of four (4) stormwater samples flowing onto the
          construction site, four (4) more stormwater samples flowing from the construction site
          into the terminal wetland, and a rain-gauge is installed on site to indicate the intensity of
          rainfall during a stormwater event (Table 11-2).

          Inflow and outflow water needs to be collected as paired samples within a short time
          frame, with each pair representing the same phase of stormwater activity. The volume
          of stormwater generated in the catchment can be calculated by the area of catchment
          and the intensity of rainfall during the event.    The proportionate change in the
          suspended solids loads in stormwater flowing over the construction site will provide a
          measure of the sediment being generated from the construction site.
