1.0 Hazardous Materials Audit 1.1 Asbestos Materials # Location Material Sample ID / Suspect Result Type/ Visual Area m/sq* Friable or Bonded Recommendations 1 Electrical Box Rear wall facing road: Bituminous fibrous Zelminite style electrical board. (Larger board is timber, smaller black board has an asbestos content) Bituminous Elect. Dist. Board 02491/1 Chrysotile Envirolab #136262 1 Bonded Remove all as Bonded Asbestos prior to demolition or refurbishment (see Appendix B: 1. Specification for the Removal of Bonded Asbestos) * NOTE TO CONTRACTORS: Area in Square Metres: The area of asbestos material is given here as an approximate quantity. Asbestos removal contractors should only rely on this figure as an indication of the scale of the amount to be removed, and should individually assess and measure the areas themselves to provide a fee proposal for the removal procedures. NON-DETECTS: NA. INSPECTION NOTES: The building is constructed of concrete blocks with a concrete roof. IMPORTANT REFURBISHMENT/DEMOLITION NOTES: If removing any concrete floor slabs, the builder/demolisher should check the sides and underneath for possible pieces of asbestos cement sheeting. These may have been used as formwork in some instances, and have been buried as waste product in other situations. Asbestos removal shall proceed as per Specifications attached.

1.2 Synthetic Mineral Fibre (SMF) Synthetic mineral fibre (SMF) insulation was NOT located during the inspection. Contingency Measure: Any synthetic mineral fibre (SMF) located during demolition or refurbishment shall be removed if the material is to be disturbed during the works, as per Appendix B: 2. Specification for the Removal of Synthetic Mineral Fibre (SMF) 1.3 PCBs in Fluorescent Light Fittings A number of older style light fittings were located throughout the building. The fittings were connected to mains power. The internal components could not be inspected. It is suspected that these fittings may contain internal capacitors or components with an internal PCB dielectric oil. Contingency Measure: Any light fittings located during demolition or refurbishment, with metal capacitors or older plastic capacitors, should be checked in the Identification of PCB - Containing Capacitors PCB (ANZECC, 1997) and if identified, removed as per Appendix B: 3. Specification for the Removal of Fluorescent Light Capacitors containing PCB Oil. Hazardous Materials Audit : King George Park Amenities, Rozelle NSW (EBG.HMA-02491.rpt) Page 4
1.4 Ceiling Space Dust with Elevated Lead Levels Findings: Ceiling space dust was not located during the inspection. Health based investigation levels for lead in soil currently accepted by EPA NSW are documented in EPA NSW Guidelines for the NSW Site Auditor Scheme (June 1998). The HBSILs are: Column 1: residential (including schools) level for lead in soil of 300mg/kg. Column 2: parks and residential open space level for lead in soil of 600mg/kg. 1.5 Lead Based Paint 1. A sample of paint was taken from the external wall paint and analysed for lead content. The sample contained <0.05% of lead. (See sample 02491/2 in Envirolab report #136262). The paint IS NOT defined as lead paint according to Australian Standard: Guide to Lead Paint Management, Part 2: Residential and Commercial Buildings (AS 4361.2-1998). In general lead paint is identified in the Australian Standard as paint having a lead content in excess of 1% by weight (10 000 kg-1). Findings: Paint containing significant levels of lead was not detected with the sample analysis. It is suspected that lead paint shall not be an issue on the external or internal walls. NOTE: In most cases external enamel paint used from the 1800s to 1970s have levels of lead above 1%. Paint samples above this figure may become a hazard if allowed to flake, peel or deteriorate in any way that allows it to come in contact with humans. Generally external enamel paint on timber in older buildings may be regarded as containing lead (i.e. >1%). In general lead paint is identified in the Australian Standard as paint having a lead content in excess of 1% by weight (10 000 kg-1).

3.0 LIMITATIONS OF THE AUDIT This report must be read in total. No part should be extracted from the whole report to be used during the demolition or refurbishment procedures. Every effort has been made to locate and identify any hazardous materials within the buildings, however hazardous materials may be located in inaccessible areas. The survey was conducted within occupied buildings. In accordance with OH&S procedures, sampling was therefore restricted and/or difficult due to the risk of exposure to asbestos fibres when this material is broken. The scope of works for this inspection did not include demolition of suspect areas. It should be noted that without substantial demolition of the buildings it is not possible to guarantee that all (or any) hazardous materials have been located. Where sampling was possible, generally one sample of the material was analysed. One sample as a part of the whole is generally deemed adequate and common practice for the assessment of asbestos. The status of the material in regard to the asbestos content has been made from analysing this one sample. If during demolition and/or refurbishment the identified materials are found not to be homogeneous, further samples should be taken and analysed. Access to confined spaces, shallow sub floors, some ceiling spaces, and within the internal confines of any plant equipment was not possible in certain circumstances. Certain assumptions were made during the inspection taking into consideration the age of the building. This document should be used as a starting point in the identification of hazardous materials, and care should be taken if refurbishment or demolition occurs. Where suspect materials are encountered, work should cease until any unidentified material has been analysed. EBG and the author take no responsibility for the hazardous nature of any asbestos or other contamination found in the buildings, within the soil or the sub surface areas of the buildings and associated facilities. EBG and the author take no responsibility for any hazardous material that may cause risk, or is causing risk, to human health.

Client Reference: 02491 Quality Control Definitions Blank: This is the component of the analytical signal which is not derived from the sample but from reagents, glassware etc, can be determined by processing solvents and reagents in exactly the same manner as for samples. Duplicate: This is the complete duplicate analysis of a sample from the process batch. If possible, the sample selected should be one where the analyte concentration is easily measurable. Matrix Spike : A portion of the sample is spiked with a known concentration of target analyte. The purpose of the matrix spike is to monitor the performance of the analytical method used and to determine whether matrix interferences exist. LCS (Laboratory Control Sample) : This comprises either a standard reference material or a control matrix (such as a blank sand or water) fortified with analytes representative of the analyte class. It is simply a check sample. Surrogate Spike: Surrogates are known additions to each sample, blank, matrix spike and LCS in a batch, of compounds which are similar to the analyte of interest, however are not expected to be found in real samples. Laboratory Acceptance Criteria Duplicate sample and matrix spike recoveries may not be reported on smaller jobs, however, were analysed at a frequency to meet or exceed NEPM requirements. All samples are tested in batches of 20. The duplicate sample RPD and matrix spike recoveries for the batch were within the laboratory acceptance criteria. Filters, swabs, wipes, tubes and badges will not have duplicate data as the whole sample is generally extracted during sample extraction. Spikes for Physical and Aggregate Tests are not applicable. For VOCs in water samples, three vials are required for duplicate or spike analysis. Duplicates: <5xPQL - any RPD is acceptable; >5xPQL - 0-50% RPD is acceptable. Matrix Spikes, LCS and Surrogate recoveries: Generally 70-130% for inorganics/metals; 60-140% for organics (+/-50% surrogates) and 10-140% for labile SVOCs (including labile surrogates), ultra trace organics and speciated phenols is acceptable. In circumstances where no duplicate and/or sample spike has been reported at 1 in 10 and/or 1 in 20 samples respectively, the sample volume submitted was insufficient in order to satisfy laboratory QA/QC protocols. When samples are received where certain analytes are outside of recommended technical holding times (THTs), the analysis has proceeded. Where analytes are on the verge of breaching THTs, every effort will be made to analyse within the THT or as soon as practicable. Where sampling dates are not provided, Envirolab are not in a position to comment on the validity of the analysis where recommended technical holding times may have been breached.
