Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 20209
Title: Operation Plan and Procedures
Start date: 24 Nov 2014
 
Licence Condition
The licensee must prepare and submit to the EPA a Waste Control Program and an Operational Program for the Buronga Landfill as detailed in the Landfill Environment Management Plan (LEMP) dated November 2012 and the Wentworth Shire Council Waste Management Strategy dated 10 November 2014. Completion Date: 1 February 2015.
Stormwater Management Assessment
By 15 September 2017, the Licensee must submit to the EPA a Stormwater Management Assessment Report for the Premises prepared by an independent and suitably qualified expert.
The Stormwater Management Assessment must: Include a site water and leachate balance for all catchments at the Premises, including: 1.      a diagram or map with the area (m2) of each catchment; 2.      flow paths of stormwater and leachate; and 3.      calculation of runoff volume from each catchment.
The Stormwater Management Assessment must:  Assess the impacts of stormwater discharges from the Premises including: 1.      A characterisation of the water quality of any discharges from the Premises to surface waters with reference to ANZECC 2000 assessment criteria for ‘slightly to moderately disturbed ecosystems’ and criteria for receiving water environmental values; 2.      Details and sampling of potential contaminants of concern that may leach from waste into the water that may be discharged; 3.      Sufficient sampling to capture the full variability of water quality discharged from the Premises, including typical to worst case scenarios, and be representative of the range of operational process which would materially impact water discharged.
The Stormwater Management Assessment must: Review and/or propose mitigation measures to manage stormwater impacts, including: 1.      measures to minimise contamination of stormwater, including at-source controls; 2.      collection and treatment of contaminated stormwater runoff; 3.      diversion of uncontaminated stormwater; 4.      sediment and erosion controls; and 5.      based on the stormwater characterisation in the condition above, propose an ongoing stormwater discharge monitoring programme.  
Assessment of Leachate Collection
The Licensee shall undertake a risk assessment and review of the leachate collection systems at the Premises. The risk assessment shall review: 1.      leachate generation from all waste storage and processing areas; 2.      adequacy of the capacity of available leachate storage; and 3.      leachate characterisation and monitoring.
