Waihi North Project Preliminary Site Investigation (Ground Contamination) Williamson Water & Land Advisory Limited 44 3.8 Coromandel Forest Park We have considered all potential HAIL activities for the Coromandel Forest Park site in Table 10 below. As no HAIL activities are present, the Park is not considered a “piece of land” under the NESCS. The NESCS therefore does not apply to the works proposed in the Park. Table 10. Potential for contamination: Coromandel Forest Park Land use Potential contaminants Possible extent of contamination HAIL Assessment Areas potentially impacted Historic mining operations HAIL Activity E7: Mining industries Cyanide, acids, metals There is potential for some minor contamination to remain around former mine workings in the immediate vicinity of the Royal Standard Battery, but no potential for these workings to impact on the proposed WUG due to the separation between the historic mine workings and proposed surface ventilation raises. HAIL Activity E7 does not apply to the site - Site description summary The Park is forested under DOC management with no modern infrastructure present. However, former mine workings are located throughout the Park. Proposed developments The WUG and Dual Tunnel will be constructed underground with the only surface expression of the WNP within the Park being four proposed ventilation raises servicing the Dual Tunnel and WUG. Site history summary An historic gold mining battery (the Royal Standard battery) is the only potential source of contamination identified within the Park.
