s53X Environmental Audit – 140 to 204 Western Avenue, Westmeadows VIC Anthony Lane Tullamarine Community Meeting, 12 March 2014
Environmental Audit Process >S53X of the Environment Protection Act, 1970 (previous audit of landfill risk was under s53V of EP Act) >EPA-appointed Auditor – engaged by site owner >Process controlled and well established system controlled by EPA guidelines >Independent and impartial – duty to environment & community protection >Condition of the Environment – all relevant ‘elements’ with segment >Land use Planning Process – used to verify that land quality suitable for use >Outcome of the Audit is either a Certificate of Environmental Audit or Statement of Environmental Audit
Audit Timeframe and Activities >May 2012 to January 2014 – Assessment of site condition by Assessors (multiple phases of investigation including remediation) >July 2012 – Auditor engaged by Transpacific >October 2012 to January 2014 - Auditor review and verification of site condition including document reviews, site inspections (multiple) and environmental monitoring (including soil and vapour sampling) >February 2014 – Audit completed and Statement of Environmental Audit issued to Transpacific, EPA and Hume City Council.
Audit Outcome >Land Contamination (Soil) and Risks – Environmental quality of land (contamination status) makes it suitable for multiple uses - commercial / industrial, public open space or residential (permitted use subject to planning authority decision). >Land Contamination (Landfill Gas and Vapour Intrusion) and Risks – no unacceptable risks from vapour derived from contaminated groundwater or landfill gas for proposed land-use of the site or nearby residential areas. >Groundwater Contamination and Risks – Groundwater is contaminated by metals, inorganic and organic compounds derived from the Closed Tullamarine Landfill. The following beneficial uses of groundwater at the site are precluded by this contamination. (These uses are not current and very unlikely to occur at the site in the future): –Agriculture, parks and gardens (irrigation) –Stock watering –Industrial water use –Primary contact recreation
Statement of Environmental Audit Statement Conditions >Condition 1 The groundwater is contaminated and unsuitable for the extractive beneficial uses: Potable Mineral Water Supply, Agricultural, Parks and Gardens, Stock Watering, Industrial and Primary Contact Recreation. Consequently, no groundwater shall be extracted at this site for such uses. >Condition 2 Groundwater Monitoring Wells (MB13, MB14, MB15, MB16, MB1, MB55U/L, MB56, MB57, MB57A, MB61, MB61L, MB69, MB72, MB73, MB74, MB75, MB76, MB80, MB83, MB85, MB86U/L, BH 1, BH2, BH3) must be maintained and remain accessible for the purpose of ongoing monitoring by the party responsible for the aftercare of the Closed Tullamarine Landfill.
Other Related Information >A Certificate of Environmental Audit was not issued due to the presence of polluted groundwater derived from sources off-site, which precludes the extractive beneficial uses of Potable Mineral Water Supply, Agricultural, Parks and Gardens, Stock Watering, Industrial and Primary Contact Recreation. >In accordance with section 13.7 of EPA Publication 759.2, the Auditor has concluded that polluted groundwater has been cleaned up to the extent practicable due to it being from an off-site source, the precluded beneficial uses are not relevant and it does not present an unacceptable risk to the use of the land. >Upon receiving this information relating to presumed groundwater pollution at the site, EPA may identify a Groundwater Quality Restricted Use Zone (GQRUZ) in accordance with Clause 19 of the SEPP (GoV). >The party responsible for the aftercare of the Closed Tullamarine Landfill will require access to the site in order to carry out the ongoing monitoring of groundwater monitoring bores (listed in Condition 2 of this statement).
