4 1 Introduction 1.1 Background JBS Environmental Pty Ltd (JBS) was engaged by Orica Australia Pty Ltd (Orica) to prepare an Asbestos Management Plan (AMP) for the information of site workers and contractors at the Southlands Development located at McPherson Street, Banksmeadow, NSW (the site). A preliminary investigation was completed in 2005 (HLA ) on stockpiled sand and soil material across the site. The resulting report from this investigation was reviewed by Charlie Furr of JBS (JBS ) and it was determined that both bonded and friable asbestos were present in stockpiled material at the site. It was recommended that any asbestos removal/remediation works should be completed by a Class A licensed asbestos removal contractor. This plan was prepared in accordance with the requirements of National Occupational Health & Safety Commission (NOHSC) "Asbestos: Code of Practice and Guidance Notes", the NSW Occupational Health and Safety Act and Regulations, NSW WorkCover Guidelines. All contractors working on the site referred to as Southlands must be provided with a copy of this plan. 1.2 Objectives This AMP has been prepared to educate site workers and contractors about the presence of bonded and friable asbestos contamination at the site and assist them with management of any future site works that may disturb the asbestos contaminated material and result in a risk to human health. 1.3 Definitions Asbestos Asbestos is the generic term for a number of naturally occurring fibrous silicate minerals (SafeWork ). There are two major groups of asbestos: The Serpentine group which contains chrysotile (white asbestos); and; The Amphibole group which contains amosite (brown asbestos) and crocidolite (blue asbestos) as well as other less common types, such as tremolite, actinolite and anthophyllite. The condition of asbestos materials can be identified as either Bonded or Friable as described in Section and Section 1.3.3, respectively. Asbestos containing materials (ACM) are any materials or things that, as part of their design, contain asbestos. 1 Factual report on Preliminary Soil Investigation Orica Botany Southlands, NSW, prepared for Orica Australia Pty Ltd by HLA-Envirosciences Pty Ltd, August 2005 (HLA 2005) 2 L002 Southlands Development, Banksmeadow JBS Environmental Pty Ltd, JBS , July 2012 (JBS 2012) 3 Model Code of Practice How to Safely Remove Asbestos, Safe Work Australia (Safe Work 2011) Asbestos Management Plan Page 2 Southlands Development, McPherson Street, Banksmeadow, NSW JBS (Revision 1)

5 1.3.2 Bonded Asbestos Bonded asbestos material is any material that contains asbestos in a bonded matrix. It may consist of Portland cement or various resins/binders, and it cannot be crushed by hand when dry (Safe Work 2011). Examples of bonded asbestos are shown in Plates 1.1 and 1.2. Plate 1.1: Bonded Asbestos as fibre cement sheeting Plate 1.2: Bonded Asbestos as fibre cement tiles(left) and corrugated sheeting (right) Friable Asbestos Friable asbestos material is any material that contains asbestos and is in the form of a powder, or can be crumbled, pulverized or reduced to powder by hand pressure when dry. Any products that have been subjected to weathering, or damaged by hail, fire or water blasting are considered to be friable (Safe Work 2011). An example of friable asbestos is shown in Plate 1.3. Plate 1.3: Friable Asbestos as pipe lagging Asbestos Management Plan Page 3 Southlands Development, McPherson Street, Banksmeadow, NSW JBS (Revision 1)

6 2 Management of Soil Contamination 2.1 Above Ground Works Site workers and contractors are not required to prepare a Contamination Management Procedure if completing any of the following non intrusive works on site: Site inspections without sampling; Site walkovers; and Any other above ground works. No specific safety or procedural requirements, other than those required by Orica upon entry to this site, are necessary for above ground works. Those site workers and contractors completing above ground works shall make themselves familiar with the Unexpected Finds Protocol outlined in Section 2.4 of this AMP. 2.2 Non Intrusive Below Ground Works Site workers and contractors are not required to prepare a Contamination Management Procedure if completing any of the following below ground non intrusive works on site: Groundwater monitoring events from existing groundwater monitoring wells. No specific safety or procedural requirements, other than those required by Orica upon entry to this site, are necessary for non intrusive below ground works. Those site workers and contractors completing non intrusive below ground works shall make themselves familiar with the Unexpected Finds Protocol outlined in Section 2.4 of this AMP. 2.3 Intrusive Below Ground Works Site workers and contractors shall be required to develop specific Contamination Management Procedures (CMPs) relating to their proposed activities if completing any of the following intrusive works on site: Relocation or removal of any material; Excavation and removal of material; Sub ground level drilling; Trenching; Grading; or Any other intrusive works. The Contamination Management Procedures shall detail the requirements of site workers and contractors when completing intrusive below grounds works for the following: Personal Protective Equipment; Contaminated material storage and handling requirements; Waste transport and disposal and any requirements for licensed asbestos removal contractors; Asbestos Management Plan Page 4 Southlands Development, McPherson Street, Banksmeadow, NSW JBS (Revision 1)

7 Human health and environmental monitoring requirements; Any validation and clearance requirements; and An unexpected finds protocol similar to that outlined in Section 2.4. The Contamination Management Procedures shall be developed in accordance with the following National Guidelines and Regulations: Work Health and Safety Regulations 2011; Model Code of Practice How to Safely Remove Asbestos (Safe Work 2011); Code of Practice for the Safe Removal of Asbestos [NOHSC:2002(2005)]; and Waste Classification Guidelines (DECC 2008). The Contamination Management Procedure may be incorporated into a Safe Work Method Statement or JSERA. 2.4 Unexpected Finds Protocol Unexpected finds include: More than 10 m 2 of bonded asbestos observed on or below the ground surface (e.g. asbestos piping or conduit) 4 ; and Suspected friable asbestos on the ground surface. Any bonded asbestos encountered that totals less than 10m 2 will still require removal, but will not require the use of licensed bonded asbestos removal contactor. The removal less than 10m 2 of bonded asbestos will still need to be completed in accordance with guidance documents listed in Section 2.3. Requirements for disposal will need to be addressed in the Contractors CMPs. As a precautionary measure to ensure the protection of site workers and contractors and the site workers and occupants of nearby land, should an unexpected find be encountered (or any other unexpected potentially hazardous substance), the procedure summarised in Figure 2.1 is to be followed. An enlarged version of the unexpected finds protocol, suitable for use on site (Appendix A), should be posted in the site office and referred to during the site induction. 4 as defined in SafeWork (2011) Asbestos Management Plan Page 5 Southlands Development, McPherson Street, Banksmeadow, NSW JBS (Revision 1)

8 Figure Unexpected Finds Protocol In the event of an unexpected find see definition Section 2.4 Immediately cease work and contact site foreman or Orica Representative Site Foreman or Orica Representative to construct temporary barricading to prevent worker access to the unexpected substance(s) and install appropriate stormwater/sediment controls Orica Representative to arrange inspection by environmental consultant Environmental consultant to undertake detailed inspection and sampling (if required) If substance assessed as not presenting an unacceptable risk to human health If substance assessed as presenting an unacceptable risk to human health Site Foreman or Orica Representative to remove safety barricades and environmental controls and continue work Environmental consultant to supervise remediation and undertake any required assessment/validation/clearance Site Foreman or Orica Representative to remove barricades and environmental controls and continue work. Environmental consultant to submit assessment/validation/clearance to site foreman and Orica Representative Asbestos Management Plan Page 6 Southlands Development, McPherson Street, Banksmeadow, NSW JBS (Revision 1)
