DWER has responsibilities under Part V of the Environmental Protection Act 1986 (the Act) for the licensing of prescribed buildings. Conditions included in the permit relate to the prevention, reduction or control of emissions and discharges into the environment and the monitoring and reporting thereof. Where other legal instruments impose obligations on the Pledge/Permit Holder, it is not the intention to include these in the permit conditions.
Permit holders are also reminded of the requirements of Article 53 of the Act, which restricts certain changes to prescribed premises, unless the changes are in accordance with a building permit, license, closure notice or environmental protection notice. If you have a license that is issued for more than one year, you must pay the annual license fee before the anniversary date of your license. If your premises have been assessed under Part IV of the Act, you may have had conditions set by the Minister for the Environment.
As part of the decision-making process, the CEO has also changed the type and style of license and issued a revised license consolidating the changes made under Amendment Notices 1 and 2 issued between 2017 and 2019 (as detailed in the instrument log below ), where . Production output also increased from 1 mtpa to 1.1 mtpa, and includes the expansion of the TSF footprint.

Inert waste type 1' has the meaning defined in Landfill Waste Classification and Waste Definitions 1996 published by the CEO and as amended from time to time;. Inert waste type 2' has the meaning defined in Landfill Waste Classification and Waste Definitions 1996 published by DEC and as amended from time to time;.
Landfill Definitions means the document entitled "Landfill Waste Classification and Waste Definitions 1996" published by the Chief Executive of the Department of Water and Environment Regulation, as amended from time to time;. NATA accredited means with respect to the analysis of a sample that the laboratory is accredited by NATA for the specified analysis at the time of analysis. Premises means the area defined on the facilities map in Table 1 and listed as the facility address on page 1 of the Licence;.
Premises operation
Nullagine Gold Operation – Golden Eagle Project 10. b) a minimum top of the freeboard of 300mm is maintained at the Process Dam; and. The disposal of waste by landfill will only take place within the landfills shown on the Site Map in Appendix 1. The separation distance between the base of the landfill and the highest groundwater level must not be less than 2 m.
Nullagine Gold Operation – Golden Eagle Project The Licensee will manage the dumping activities to ensure:. a) the size of the tilting surface is limited to a minimum and is not greater than 30 m in length and 2 m above ground level in height;. To be covered by the end of the working day in which the waste was dumped with sufficient quantities of type 1 inert waste or clean fill to prevent the spread of fire and the harboring of disease vectors. The underdrainage system discharges any collected water into a water return sump as depicted in Figure 1 of Schedule 1;.
Nullagine Gold Operation – Golden Eagle Project 13. e) includes two recovery wells TSFB002 and TSFB003 on the west and east sides of TSF2 and pump-back system to deal with any potential seepage as depicted on the production well map in Schedule 1;. g) groundwater monitoring boreholes KCB07F, KCB12, KCB41, TSFB001 depicted on the map of monitoring locations in Schedule 1 with baseline monitoring performed by the parameters listed in Table 3.4.1;. h) have the two production wells KCB12 and KCB12B act as an interception with a pumping back system should they be required to deal with any seepage as shown on the map of production wells in schedule 1;. j) maintained to have an overall freeboard of 500mm above storm water capacity height and an operational freeboard of 300mm;. k) have the centrally located decanting structures maintained to recover the highest percentage of process water in each cell. Piping in bundled trenches, maintained with sufficient capacity to contain any spillage for a period equal to the time between routine inspections Return water piping maintained with a series of valves to allow water to be diverted into the tailings piping for flushing purposes via collection points. Flow meters located at the start and end of the tailings pipeline to monitor flow and pressure loss.
In the event of pipeline failure, the shift supervisor should be notified and the pipeline closed until the repaired Spigots are stored at approximately 20m centers around the perimeter of TSF2.
