05. Town Planning Report · MCU10/2127

3.4 Surface Capping and Protective Barriers Containment cells have been constructed beneath
buildings G and I as shown on Figure 1. The concrete building slab over these containment cells must be
maintained in a sound condition at all times. No excavation into these containment cells is permitted
unless written approval is obtained from the Administering Authority.

The concrete shotcreted area on the eastern portion of the site as shown on Figure 1 must also be
maintained in a sound condition at ali times. No excavation through the shotcreted area is permitted
unless written approval is obtained from the Administering Authority.

If for any reason the capping over these concreted areas is disturbed it must be immediately replaced.

Slope stability and erosion controls must be maintained in the open space area identified on Figure 1 to
ensure that contaminated soils in this area do not migrate to other areas of the site.

3.5 Soil Excavation and Removal Off-site disposal of contaminated soil must only be conducted
after obtaining prior approval from the Administering Authority under Section 424 of the Environmental
Protection Act 1994 (EP Act) or equivalent.

Representative sampling and analysis of excavated soil from contaminated areas must be performed by a
suitably qualified and experienced person in accordance with Section 381 of the EP Act.

3.6 Unexpected Contamination If during any site earthworks or excavation, offensive or noxious
odours and/or evidence of gross contamination not previously detected is observed, site works are to
cease in that area and action taken to immediately abate the environmental harm. The Administering
Authority is to be notified in writing within 2 business days of detection and advised of appropriate
remedial action.

Any remedial action is to be developed by an appropriately qualified and experienced person in according
to Section 381 of the EP Act. Administering Authority approval is required before site works can re-
commence in the area.

3.7. General Environmental Protection Any earthworks are to be undertaken in accordance with
general environmental protection measures to avoid unwanted migration and deposition of soil. These
measures include the control of dust, noise, stormwater runoff, sediment, erosion, spillage from haulage
trucks and odour releases involving the handling or movement of contaminated material. Contaminated
soil that is excavated and temporarily stored on site must be managed such that environmental harm is
prevented. All excavation of contaminated soil is to be documented and records kept which demonstrate
SMP compliance.

3.8 Workplace Health & Safety A Workplace Health and Safety Plan (WH&S plan), which
conforms to the requirements of the Workplace Health and Safety Act 1995 is to be developed for any site
excavation works in contaminated areas. The WH&S plan must specifically address contaminants of
concern and appropriate safety measures for site workers and the general public.

3.9 Third Party Reviewer (TPR) A TPR approved by the DERM and operating within the DERM
Terms of Reference for TPR (February 2008 or subsequent) must be appointed for any future site
assessment and remediation activities.

3.10 Underground Services Installation of underground services within the containment cells
should be avoided. If it is not possible to avoid placing services through the containment cell then
approval from the Administering Authority must be obtained under Section 3.4 of this SMP (note the
Administering Authority is not obliged to approve any application to install services through the
containment cell).
