As with the existing Regulated Structures contained in the EA, the Upper Mundic Gully TSF will be subjected to annual regular maintenance inspections in accordance with EA conditions in Schedule H and the Manual for Assessing Consequence Categories and Hydraulic Performance of Structures (ESR/2016/1933) . These inspections must be undertaken by a suitably qualified and experience person. In addition to these inspections, the Heritage Minerals Water Management Procedure provides standard controls for various Project activities including tailings and water management, chemical and hazardous material storage, and wastewater management in accordance with environmental best practice and relevant guidelines and standards. 7.4.3.1 Groundwater Monitoring The proposed amendment will not introduce any new contaminants of concern or increase current observed concentrations of potential contaminants. Given the lack of groundwater monitoring bores within the Upper Mundic Gully area, the installation of groundwater monitoring bores prior to construction is proposed as conditions in the EA to support this amendment. Groundwater quality is proposed to be monitored for contaminants of concern in accordance with the suggested amendments to conditions in the EA.
