Summary
 
Licence number: 1095
Title: Low pH Water Investigation and Management
Start date: 02 Oct 2023
 
Licence Condition
The licensee must engage a suitably qualified person to undertake an investigation of low pH surface and groundwater within the vicinity of the Environmental Dam and former coal washery tailings dams. The investigation must incorporate, but not necessarily be limited to, the following components: Investigation - characterise the chemical composition of the low pH water and determine the lateral extent and the source of this contamination. Management - identify all appropriate short, mid and long term management options that can be reasonably and feasibly implemented to minimise the migration of any contaminated surface and/or groundwater contamination from its source (prior to source remediation) and how the effectiveness of such actions will be measured. Remediation/Rehabilitation - identify all appropriate options available to the licensee to remediate and/or rehabilitate that portion of the premises that may be causing the contaminated water. Time frames - for points 2 and 3 above, identify the time frames for all of the options identified. Preferred options - where a number of options have been identified under points 2 and 3 above, the report must list these options in order of preference and provide a description of the advantages and disadvantages for each option.
By no later than 5:00 pm on 31 October 2023, the licensee must notify the EPA in writing (info@epa.nsw.gov.au) of the appropriately qualified person that will be engaged to undertake the investigations required under condition U1.1 above.
By no later than 5:00 pm on 17 November 2023, the licensee must provide the EPA with a copy of the proposed scope of works for the investigation that is required under condition U1.1.
By no later than 5:00 pm on 16 February 2024, the licensee must provide the EPA with a report that summarises the findings of the investigation required by condition U1.1.
Notwithstanding conditions U1.2 to U1.4, the licensee must immediately undertake all reasonable and feasible actions that will minimise the potential for contaminated surface water to impact on off-site receiving waters. Such action may include the routine pumping of water from all dams immediately below the Environmental Dam back on to the premises.
The licensee must prepare monthly summary reports (submitted by 5:00 pm on the last Friday of each month starting from October 2023) summarising the actions completed that month with respect to managing the contaminated water issue including the progression of the investigation and of any remedial/rehabilitation works on the premises.
