Waihi North Project Preliminary Site Investigation (Ground Contamination) Williamson Water & Land Advisory Limited 21 2.2.6 Proposed Northern Rock Stack Northern Rock Stack (NRS), Figure 7: The proposed NRS site is situated northeast of the existing Processing Plant and WTP site and immediately north of TSF2. It includes an existing workshop and hardstand area and farmland. An un-named stream (tributary of the Ohinemuri River), whose riparian margin is lined with maturing native vegetation (Photograph 41), traverses north south, separating the site approximately in half. A vegetated hill occurs partially within the site on the eastern boundary with other small depressions orientated east/west (Photograph 42). • The workshop is on a raised platform in the central south of the site (Photograph 38). An access road and hardstand area occur adjacent to its eastern side. A large, modern self-bunded diesel Above-ground Storage Tank (“AST”) is on the western boundary of the platform (Photograph 37). The workshop is a large steel framed corrugated iron clad/ roofed structure. Waste oil collection vessels/ tanks are present outside the southwestern corner of the workshop (Photograph 38). • The farmed portion of the NRS site is accessed off Golden Valley Road. It is currently used for livestock grazing (calves and bulls were being reared at the time of the inspection). There are four structures within this part of the site, including a disused small dairy shed, two hay sheds and a dwelling. - The two sheds have earth floors and are timber framed and corrugated iron clad (Photographs 39 and 40). - The dairy shed is also of corrugated iron construction and is overgrown with vegetation. - A dwelling is situated east and north of the farm buildings. It is a weatherboard structure with an iron roof. Cement board cladding (eaves and soffits) may contain asbestos. Photograph 37. Diesel AST adjacent to workshop. Photograph 38.
