This document is a technical annexure for the Yzermyn Underground Coal Mine, detailing the design and infrastructure for water use authorisation. It covers the construction of the adit platform, administration and workshop facilities, sewage and water treatment plants, waste management, and a comprehensive stormwater management plan designed to separate clean and dirty water.

• The construction of the adit platform will require approximately 84,446 m3 of fill material, which will be sourced from the development of the high-wall/adit entrance and the sinking of decline shafts.
• The mine will utilize a Bio-Mite waste water treatment plant (WWTP) with a capacity to treat sewage for 300 people, using anaerobic and aerobic processes to reduce the Biochemical Oxygen Demand (BOD) load by up to 40% in the first stage.
• A modular water treatment plant will be installed during the operational phase and maintained after mine closure to treat decant. The system will use defused air floatation and/or ultrafiltration, followed by reverse osmosis for salinity removal and an ion exchange column for nitrates.
• Brine from water treatment will be processed via freeze crystallisation to produce purified solvent and salt crystals, which will be disposed of as hazardous waste by a registered contractor.
• The mine's explosives magazine will store no more than 1,000 kg of explosives and must comply with the OHSA GNR.109 of 2003 and the Fire Brigade Services Act (No. 99 of 1987).
• The adit development involves a 10-degree dip towards the high-wall, with soft material stripped to seven metres and battered at a 1:5 slope. The total adit footprint is calculated at 2.451 ha.
• A 107m deep upcast ventilation shaft will be installed using a raise-bore approach once mining on the Dundas seam has commenced.
• The stormwater management plan uses a dual Pollution Control Dam (PCD) system to prevent spillages during peak summer rainfall and avoid dry runs in winter. This consists of PC Dam 1 (an HDPE open dam with a volume of 23,000 m3) and seven sectional steel tanks with a combined capacity of 7,742 m3 to reduce evaporation.
