           Herbicide monitoring in stormwater entering and leaving the construction site should be
           performed when applications are known to occur, rather than routinely.           Some
           herbicides have a short residence time, so arrangements may need to be made with the
           laboratory for rapid courier service and turnaround time. The monitoring schedule is
           listed in Table 11-3

11.2         Water Quality Monitoring During Routine Operation of the Essence of Peregian

           Sampling should be performed at sites 1 to 9. The temporal sampling frequency is
           recommended at monthly intervals for the first 12 months, with quarterly sampling
           thereafter (Table 11-3). This temporal frequency is intended to show the proportional
           improvement from the existing water quality condition in response to improved
           stormwater management associated with the new development. Seasonal variations
           can be identified from the quarterly samples. Herbicide monitoring is as described for
           the construction phase.
