Over the years, new monitoring sites have been added and others removed to accommodate changes in the mining operation and the locations of sensitive receptors. Monitoring of PM10 and respirable silica has also been carried out biennially along with other specific monitoring of some contaminants. At present, OGNZL has a total of 11 permanent monitoring sites of which 8 are used to measure deposited dust and 6 are used to measure TSP. The TSP monitoring sites are located in Waihi township and/or close to Martha Pit. Meteorological parameters are measured at one location. The locations of the current monitoring sites are shown in Figure 6-1 and a description of each site is provided in Table 6-1. Figure 6-1.
