1 INTRODUCTION AND OBJECTIVES

1.1 INTRODUCTION

This report presents the findings of a limited Contaminated Site Investigation (CSI) performed at the United Service Station located on the corner of Banna Avenue and Bonegilla Street, Griffith, NSW (the site). Mr Martin Ruggeri of PlanningMatters Development Services commissioned the report on behalf of the property owner in response to Aitken Rowe Testing Laboratory P/L (ARTL) quotation (ARTL ref: Q10-315) dated 20th December 2010. It is understood that the current owner is assessing future options for the site and it is the purpose of this investigation to aid in the decision process. This amended report has been completed following advice PlanningMatters that the proposed future use of the site will be a retail bottle shop. It should be noted that this limited CSI has been completed without satisfying the NSW EPA sampling design guidelines for such sites.

1.2 OBJECTIVES

The main objectives of this limited CSI are to:

• Briefly document the site history.

• Assess potential sources of contamination.

• Assess the risk of these contaminant sources with respect to

the contamination status of the site.

• Conclude whether or not the site is suitable for continued

use as zoned without further assessment, or provide

recommendations for further assessment (if required) to

enable such conclusions.

2 SCOPE OF WORK

The scope of work undertaken by ARTL to meet the objectives comprised the following:

• Review of historical information including local Council information, anecdotal information and a search for previous investigations performed for the site.

• Review of geology, topography and hydrology of the site.

• Detailed site inspection and investigation including

and commercial properties immediately west and south. Further to the south lies Yambil Street and further west lies Jondaryan Avenue. 3.4 TOPOGRAPHY AND HYDROLOGY The natural topography of the site comprises slope gradients of less than 1% with a relief of less than 0.5m that form the generally flat floodplain of the Murrumbidgee River catchment. Onsite activities have ensured that surface runoff flows toward stormwater drains and associated network to the north and east. In times of excessive rain it is assumed that water would infiltrate the underlying materials through permeable areas of the site and infiltrate the groundwater system. Depth to groundwater is not known at the site.

3.5 GEOLOGY The general topography of the area is mainly flat. The 1:250,000 scale Geological Series sheet (SI 55-10) for Narrandera indicates that the area is underlain by flood plain deposits of Cainozoic Age, composed of gravel, sand, silt and clay which appeared to be underlain by Jimberro member of Cocoparra Group of Late Devonian Age, comprising sandstone and siltstone. The borehole investigation performed revealed that the site is underlain by a concrete slab to 0.1m overlying fill comprising fine to coarse grained sandy gravel and silty clayey sand which in turn is underlain by natural medium to high plasticity silty clay extending to the borehole refusal depth of 2.2m in BH1, 1.9m in BH2 and 2.9m in BH3. The borehole refusal on site appeared to be encountered on underlying floaters. Groundwater was not encountered in the excavation depth of 2.9m however it should be noted that variations to the water table level could fluctuate with changes to the season, temperature and rainfall. The borehole location plan is attached in Appendix A and borehole logs with explanatory note in Appendix B.

4 SITE HISTORY The site was originally developed and used as a fuel station which it remains as today. Discussions with PlanningMatters Development Services suggested that the owner has been thorough in maintaining stocktake records of fuel purchased versus fuel sold. To date there have been no significant discrepancies. A search of the NSW EPA website registered no current statutory notices issued under the provisions of the Contaminated Land Management Act 1997.

5 POTENTIAL SOURCES OF CONTAMINATION Based on the site history and site inspection, the potential

contaminants of concern are displayed in Table 2 below. Table 2: Summary of potential contamination sources/contaminants of concern from the fuel bowser area.

6 FATE OF CONTAMINANTS The fate of contaminants released into the environment is dependent on the properties of the chemicals and subsurface conditions. The available information indicates that the contaminants are likely to be liquid (hydrocarbons, BTEX and Lead).

7 RESULTS All analysis was undertaken by EnviroLab Pty Ltd, a NATA

accredited laboratory in Sydney. Quality assurance techniques were as per Labmark internal procedures. The laboratory test reports as received from EnviroLab Pty Ltd are attached in Appendix C.

Three boreholes (BH1, BH2 and BH3) were excavated immediately adjacent to the UPST’s to depths of 1.9m to 2.9m Below Ground Level (BGL). A total of 9 samples were taken at various depths for analysis. Table 3 summarises the analytical results and compares them to the following guidelines:

8 DISCUSSION OF RESULTS

As can be seen from Table 3 above sample 1C was found to have concentration of 1660mg/kg for TPH (C10-C36) which is above the guideline value (1000mg/kg) for sensitive land use. All other analytes for all samples were either not detected or had concentrations below the guideline value for sensitive land use.

9 COMMENTS AND RECOMMENDATIONS

One sample only was found to be above the threshold concentration for sensitive land use as given by the NSW EPA for TPH (C10-C36).

The level of contamination is, however considered slight. Based on the fact that the property owner has apparently been following a strict stocktake of fuel purchased versus fuel sold it is likely that the cause of contamination is due to overfilling of the UPST as opposed to UPST failure. In addition the risk of human exposure is considered slight to non-existent due to the depth BGL of contamination and the majority of the site is covered (capped) with concrete. There is a risk of the contamination plume migrating off site or into groundwater. Again this risk is considered slight.

The following is recommended for the site to continue operating as a

service station;

1) Ensure fuel delivery operators are following appropriate due diligence process to reduce UPST overfilling.

2) Have suitably qualified personnel to perform integrity testing on the UPST’s and associated pipework to ensure there are no leaks.

3) Perform a detailed CSI that adheres to the minimum sampling

and analysis design guidelines to gain an understanding of the extent of contamination at the site.

4) Ensure the Protection of the Environment Operations (Underground Petroleum Storage Systems) Regulation 2008 is being adhered including the installation of groundwater monitoring wells and development of an Underground Petroleum Storage System management plan.

The following is recommended if the site use is changed from a service station to a retail bottle shop; 1) Have suitably qualified personnel decommission the UPST’s by

removal/disposal and backfilling the excavation with clean fill or by filling the UPST’s with a concrete slurry or similar. WorkCover should be notified of the decommission process.

2) If the UPST’s are excavated then a validation investigation should be completed to ensure any contaminated material has been removed for remediation and/or disposal.

3) If the UPST’s are to be filled with concrete slurry it is highly recommended to have suitably qualified personnel to perform further soil contaminant testing, particularly in the location of BH1. This will provide further understanding of the extent of contamination.

4) Following the decommissioning of the UPST’s the entire site should be capped with a concrete slab of at least 0.15m

ADDENDUM

LIMITS OF INVESTIGATION

The recommendations made in this report are based on the assumption that the test results are representative of the overall subsurface conditions. However, it should be noted that even under optimum circumstances, actual conditions in some parts of the site may differ from those said to exist, because no environmental consultant, no matter how qualified, and no subsurface exploration program, no matter how comprehensive, can reveal all that is hidden by earth, rock and time. The client should also be aware that our recommendations refer only to our test site locations and the ground level at the time of testing. The recommendations in this report are based on the following:-

a) The information gained from this investigation b) The results received from a NATA accredited environmental laboratory c) Historical information d) Information supplied by the client
