The Power Station Site
Consistent with the National Environment Protection (Assessment of Site Contamination) Measure 1999 (as amended 2013) (NEPM), Alcoa will commission a series of Tier 1 preliminary site investigations to identify the potential nature and extent of contamination at the site, resulting from historical land use and activities.
Based on the outcomes of Tier 1 preliminary investigations, detailed investigations and site specific risk assessments may be undertaken to enable future site management strategies to be devised.
As with the associated mine site, Alcoa’s strong commitment to its values of health, safety and protection of the environment are key priorities for this process.
Statutory Clean Up Notice
On 13 October 2015, the Environment Protection Authority (EPA) Victoria issued Alcoa with a statutory Clean Up Notice requiring the company to manage environmental contamination at the power station site in preparation for future use.
The Clean Up Notice follows due process for an industrial site and is consistent with the NEPM approach. To date no unexpected matters have been identified by Alcoa or EPA Victoria.
The Notice requires the completion of environmental site assessments by 30 September 2017, and the appointment of an independent environmental auditor to assess the processes undertaken and to provide independent reports to EPA Victoria.
Alcoa is also required to provide a written update to EPA Victoria every quarter and will publish each update on its website.
Under license with the EPA, Alcoa has operated and maintained an onsite asbestos landfill on the power station site for the disposal of asbestos used in the original construction of the power station.
The operation of this landfill is regularly audited. The landfill will be used during power station decommissioning activities and will remain under license to the EPA during this period. The landfill will be regulated once closed through a separate statutory notice process with the EPA.
