EXECUTIVE SUMMARY

Background

This report addresses a proposed re-zoning for an approved community title subdivision (DA/95/457) located

on the corner of Coopers Shoot Road and Piccadilly Hill Road, Coopers Shoot NSW 2479. The report also

address the future construction of a single dwelling on Lots 1 & 3. The objective is to amend the Byron L.E.P.

2014 to extend the R5 Larger Lot Residential Zone to cover the area of Lots 2 to 5 of the current Community

Title Subdivision, which has been approved by Byron Shire Council. Lot 1 of that Community Title will retain its

current RU2 Rural Landscape Zone, having an area of 11.64 ha. The outcome of the proposal will allow for a

Torrens Title subdivision of five (5) lots.

To address State Environmental Planning Policy No 55 Remediation of Land (SEPP 55) requirements for the

development application, HMC Environmental Consulting (HMC) was engaged by the proponents to complete

a Preliminary Site Investigation (PSI) assessing potential site contamination from current and past land use and

the suitability of the site for the proposed land use.

A PSI, including a desktop assessment and site inspection, indicated the site was and currently still is used for

grazing cattle and residential purposes The site inspection revealed no evidence of intensive agricultural

farming, cattle dips or historical farm dumps or storage of residual chemicals.

Scope of Works

The scope of work undertaken during the investigation included the following:

• A desktop assessment of current and former land use including search of available records and

interviews with persons associated with the site.

• A detailed site inspection.

• Preparation of a Preliminary Site Investigation report including:

- summary of available land use history information, interviews and results of the site

inspection.

- suitability of site for current and proposed land use

- conclusions and recommendations

Conclusion/Recommendations Summary

The Preliminary Site Investigation conclusions are based on the information described in this report and

Appendices and should be read in conjunction with the complete report, including Section 11 Limitations.

A review of available historical information, and a detailed site inspection, indicated no past or present

potential contaminating land activities on site.

In relation to potential site contamination associated with the current and former land use, the subject

properties of Lot 3 DP 592005 and Lot 1 DP 1124504, 4 Piccadilly Hill Road, Coopers Shoot NSW as shown in

Appendix 2 of this report, is considered suitable for the proposed rezoning and rural and residential land uses.

No further investigation or remediation is required.

The findings of this report are based on the objectives and scope of work outlined in Section 1. HMC

Environmental has performed the services in a manner consistent with the normal level of care and expertise

exercised by members of the environmental assessment profession. No warranties or guarantees expressed or

implied, are given. This report does not comment on any regulatory issues arising from the findings, for which

a legal opinion should be sought. This report relates only to the objectives and scope of work stated, and does

not relate to any other works undertaken for the client. The report and conclusions are based on the

information obtained at the time of the assessment.

The site history and associated uses, areas of use, and potential contaminants were determined based on the

activities described in the scope of work. Additional site information held by the client, regulatory authorities

or in the public domain, which was not provided to HMC Environmental or was not sourced by HMC

8 GLOSSARY

Added contaminant limit (ACL) is the added concentration of a contaminant above which further appropriate

investigation and evaluation of the impact on ecological values will be required. ACL values are generated in

the process of deriving ecological investigation levels (EILs).

Ambient background concentration (ABC) of a contaminant is the soil concentration in a specified locality that

is the sum of the naturally occurring background and the contaminant levels that have been introduced from

diffuse or non-point sources by general anthropogenic activity not attributable to industrial, commercial or

agricultural activities.

An area of ecological significance is one where the planning provisions or land use designation is for the

primary intention of conserving and protecting the natural environment. This would include national parks,

state parks, and wilderness areas and designated conservation areas.

Bioavailability is a generic term defined as the fraction of a contaminant that is absorbed into the body

following dermal contact, ingestion or inhalation.

Bonded asbestos-cement-material (bonded ACM) comprises bonded asbestos containing material which is in

sound condition (although possibly broken or fragmented), and is restricted to material that cannot pass a 7

mm x 7 mm sieve. This sieve size is selected as it approximates the thickness of common asbestos cement

sheeting and for fragments to be smaller than this would imply a high degree of damage and potential for fibre

release.

Conceptual site model (CSM) is a description of a site including the environmental setting, geological,

hydrogeological and soil characteristics together with the nature and distribution of contaminants. Potentially

exposed populations and exposure pathways are identified. Presentation is usually graphical or tabular with

accompanying explanatory text.

Contamination means the condition of land or water where any chemical substance or waste has been added

as a direct or indirect result of human activity at above background level and represents, or potentially

represents, an adverse health or environmental impact.

Ecological investigation levels (EILs) are the concentrations of contaminants above which further appropriate

investigation and evaluation will be required. EILs depend on specific soil physicochemical properties and land

use scenarios and generally apply to the top 2 m of soil. EILs may also be referred to as soil quality guidelines

in Schedules B5b and B5c.

Health investigation levels (HILs) are the concentrations of a contaminant above which further appropriate

investigation and evaluation will be required. HILs are generic to all soil types and generally apply to the top 3

m of soil.

Health risk assessment (HRA) is the process of estimating the potential impact of a chemical, biological or

physical agent on a specified human population system under a specific set of conditions.

Investigation levels and screening levels are the concentrations of a contaminant above which further

appropriate investigation and evaluation will be required. Investigation and screening levels provide the basis

of Tier 1 risk assessment.



Multiple-lines-of-evidence approach is the process for evaluating and integrating information from different

sources of data and uses best professional judgement to assess the consistency and plausibility of the

conclusions which can be drawn.

Risk assessment is the process of estimating the potential impact of a chemical, physical, microbiological or

psychosocial hazard on a specified human population or ecological system under a specific set of conditions

and for a certain timeframe.

Risk management is a decision-making process involving consideration of political, social, economic and

technical factors with relevant risk assessment information relating to a hazard to determine an appropriate

course of action.

Screening is the process of comparison of site data to screening criteria to obtain a rapid assessment of

contaminants of potential concern.

Tier 1 assessment is a risk-based analysis comparing site data with investigation and screening levels for

various land uses to determine the need for further assessment or development of an appropriate

management strategy.
