Supporting Technical Assessments

11 | P a g e Class 1 Location Assessment Development Site – Surface Magazine, Waihi North Project The storage capacities are expected to meet the operational requirements. At times the class 1 product replenishment schedule will be adjusted to meet operational requirements (e.g., during peak usage periods). Once the storage facility has been constructed, the IMD and offset distances to buildings and infrastructure will require checking to confirm that the designed storage capacities remain compliant (or require amendment) prior to the Compliance Certifier issuing the Location Certificate. Provided all other conditions of a ‘Location Compliance Certificate’ are assessed as satisfactory by an independent Compliance Certifier at the time of construction, the proposed class 1 storage location is considered appropriate in its positioning and proposed capacities.
