                                                       Westcon Site Management Pty Ltd



4.1.1 General

          Unless specified, the location of any areas requiring earthworks or excavation is required
          to be verified for contaminated materials (eg. acid sulphate soils, asbestos or chemicals) or
          cultural significance. This is done by ensuring that sites where construction activities are to
          take place are not listed on the Environmental Management Register managed by the
          Environmental Protection Agency (EPA) and/or by soil testing. This is, typically, be the
          responsibility of the insurance and owner clients, unless it has been delegated in the
          contract.

          Topsoil and excavated materials that is to be re-used for re-vegetation is to be stockpiled in
          designated areas. Stockpile surfaces that are likely to be exposed for lengthy periods are to
          be provided with temporary erosion control measures, such as being sprayed with
          hydromulch or covered with tarpaulins. Silt fencing is also to be placed around the base of
          the stockpile.

          The Director or Site Manager is required to ensure that excavated materials that have been
          treated to neutralise contaminants is to be reused or disposed of as directed or specified.

          The Director or Site Manager is required to ensure that any fill imported by subcontracted
          services is obtained from sites free from contamination and fire ants and certificates are to
          be sighted where required from the supplier to confirm compliance with requirement.

4.1.2 Contaminated Soils

          The Director or Site Manager is required to ensure that sites identified as contaminated,
          approval from the client and/or the relevant authority must be obtained for the proposed
          activities before work commences. He is required to ensure that subcontracted personnel,
          engaged in the removal of contaminated materials, are to be adequately protected with
          appropriate personal protective equipment.

          All excavated contaminated materials must be segregated from any clean material and
          must be treated or maintained so that dust is not produced, and contamination of the
          groundwater is prevented.

          The Director or Site Manager is required to ensure that the subcontracted soil removal
          agent has selected licensed and approved transport operators for the transport of
          contaminated materials and that waste disposal dockets are used to record adequate
          tracking and recording of the chain of custody of the contaminated material occurs.
