Dewatering is required to remove excess storm water (rainfall runoff) which has accumulated primarily in the old quarry pit void and smaller sediment dams on the site over the last several years. Extensive studies have been completed by various experts over the last two years in consultation with the NSW Environmental Protection Authority (EPA) to develop an appropriate dewatering program. The pattern of water release will not be continuous and seeks to mimic the naturally intermittent flows of Blaxland Creek and its wet and dry spells in order to protect stream integrity and ecology.
-
The approval for the 星火电竞 includes use of the former quarry void to emplace various residual materials, which can’t be recovered and recycled by the operation. The rainwater currently accumulated in the void needs to be removed before construction works for the emplacement area can commence.
-
The overall volume of water onsite (approximately 445ML) will be dewatered over a period of a few months in a careful program specifically designed to protect the creek. This includes steady increases and decreases to control water levels, regular stoppages overnight, and planned ‘dry spells’. A state-of-the-art pumping and dewatering system is being used to achieve this.
-
星火电竞 will use submersible pumps to remove the water from the void. The overall system has very low noise. The water is carefully monitored and treated if required (for sediment or pH balance) prior to its controlled release via a licenced discharge point (LDP) feeding into Blaxland Creek via a designed spillway. The LDP is continuously monitored with sensors, supported by regular laboratory testing. This presentation provides a more detailed overview of the process.
-
Specific limits for discharge water quality and quantity are set within the Environmental Protection Licence (EPL) for the site issued by the EPA. Additionally, a dedicated dewatering management plan, developed in consultation with the EPA, includes more detailed compliance criteria.
-
No. Extensive water testing onsite and within the creek is central to the dewatering process. Water is closely examined at several points along the extraction route to ensure it meets the discharge criteria set by the EPA. Discharges shut off automatically if the continuous monitoring detects any problems. Specialist water consultants will be on site every day to ensure the dewatering system is operating as required to meet discharge requirements.
-
Submersible pumps, which are quieter than alternative external pumping equipment, have been selected. We will ensure the noise levels remain within approved limits of the conditions of consent. Our specialists advise us that the sound of the pumping is not expected to be particularly audible from residential areas.
-
The comprehensive assessments of the potential environmental impacts of dewatering included detailed studies for aquatic ecology. We have implemented special protection around the pipe inlets in the void to ensure no harm is caused to fauna such as turtles, eels, fish (if present) or frogs. Fauna found currently living in the water in the quarry pit will be relocated to new habitat by ecology experts.
-
The dewatering at Patons Lane RCC is expected to take approximately three months to complete.
-
The dewatering will operate during the same hours as our conditions of consent for the 星火电竞 . The hours of operation are 7am – 6pm Monday to Friday and 7am to Midday on Saturday. As noted earlier above, to reflect natural creek flows, planned ‘dry spells’ will also occur following each month of discharge (‘wet spell’).
