1 INTRODUCTION This report has been written for the purpose of providing an environmental management plan (EMP) for post capping works at the Castlemaine Rifle Range, Tomkies Road, Castlemaine, Victoria (the site). The capping works were in response to a Clean-up Notice issued by EPA Victoria on 5 September 2007 and approved by the Environmental Auditor, Anthony Lane (Cardno Lane Piper). A second Pollution Abatement Notice (PAN) was issued on 23 February 2011 by EPA Victoria to ensure appropriate management and monitoring during the site capping works. The site location is presented in Figure 1. There are currently no plans to redevelop the site, however, any works being undertaken on the site post capping have the potential to disturb the capped foundry sands which are known to be impacted. The capped area and site layout are presented in Figure 2. As such, the primary purpose of this EMP is to present a guiding document that provides information on the control and management of impacted sub-soils. Reports from previous environmental assessments were reviewed as part of the development of this EMP. Reports have indicated that concentrations of chemicals of concern (COC) in soil (and foundry sand) were protective of both human health and the environment, with the exception of copper (Cu), lead (Pb), nickel (Ni) and tin (Sn). The elevated heavy metal concentrations were generally restricted to the foundry sand (only). This plan has been developed for a number of reasons, including reducing the potential for site users to be exposed to potentially impacted materials. The potential site users include:

• site construction workers;

• visitors and tenants; and

• users of neighbouring properties. Due to the dynamic nature of the site, this plan may need to be reviewed and may be revised and re-issued (if required) throughout the life of the project, to ensure it remains relevant to the work in hand. This will provide the assurance to all stakeholders and the community that all environmental issues are addressed adequately. The requirements of this plan are applicable to all onsite activities relating to any intrusive maintenance of the site. All subcontractors and suppliers will be bound to comply with the requirements of this plan, as far as they apply to the nature and scope of their work.

2 OBJECTIVES The objectives of this management plan are to allow the owner and tenants to make informed decisions regarding activities on the land that may impact on environmental and health issues for ongoing recreational/open space use. This plan also aims to provide relevant guidance, to ensure that matters arising from the condition of soil and groundwater on and under the land can be managed appropriately. It will not replace any legislative requirements applicable to the land.

211097_EMP.doc 6

3 ACTIVITIES TRIGGERING MANAGEMENT The cap has been designed to contain the foundry sands onsite and require appropriate management to ensure there is no escape of the potentially impacted material through erosion or site activities. A stylised cross section of the capped area is presented in Figure 3 and highlights that the cap is approximately 0.6 m thick and has been topped off with 0.3 m of vegetated topsoil. Activities undertaken onsite which will disturb the cap or the soil beneath the cap will require management. As a guide, some of the activities that are considered to require management include, but are not limited to, the following:

• installation and maintenance of in ground services;

• excavation and trenching;

• alterations to firing mounds on the capped area;

• posthole drilling; and

• development of buildings on the capped area.

4 EXPOSURE PATHWAY ASSESSMENT The COC in soil at this site are primarily heavy metals copper (Cu), lead (Pb), nickel (Ni) and tin (Sn). These metals are associated with the historic deposition of foundry sands onsite. Although the impacted soil has now been capped, a residual impact remains. The following potential exposure pathways are noted, together with likelihood that the pathway may exist and comment.

TABLE 1 EXPOSURE PATHWAY ASSESSMENT

Beneficial user Pathway

Comment Dermal Ingestion Vapour

Surrounding residents, site users No No No

No access to sands as the engineered cap covers all

impacted material.

Visitors to the site No No No

No access to contaminated material following the

completion of the engineered cap.

Construction workers Potential Potential No

Builders may contact potentially impacted soil and

should apply the strategy outlined in this EMP.

Note: If the cap loses integrity allowing access and possible erosion of the contained foundry sands the likelihood of exposure

by both dermal contact and ingestion will change to ‘Potential’ in the above table.

The potential for vapour generation to affect construction workers during any post development maintenance works is negligible, due to the non-volatile nature of the material and the COC.

211097_EMP.doc 7

This limited exposure pathway assessment indicates that regular site users are unlikely to be exposed to potential impacted material, however, construction/building workers may be. Procedures are therefore required to manage this potential risk and reduce the potential for exposure.

5 LEGISLATIVE FRAMEWORK There are a series of legislative acts, regulations and guidelines which may be relevant during this project. A full list of documents which may be used, where relevant, in setting goals and limits for environmental control procedures are included in the references. The legislation and guidelines most likely to have an impact on the project are as follows:

• Environment Protection (Industrial Waste Resource) Regulations (2009);

• Environment Protection Authority (EPA) Victoria - Industrial Waste Resource Guidelines (2009);

• EPA Victoria Publication 480 - Environmental Guidelines for Major Construction sites, Best Practice Environmental Management Series (1996);

• State Environment Protection Policy - Prevention and Management of Contamination of Land (2002);

• Standards Australia 3798 (AS3798) Guidelines on earthworks for commercial and residential developments (2007), amended 2008;

• Environment Protection Act (1970);

• National Occupation Health and Safety Council - National Exposure Standards for atmospheric contaminants in the occupational environment (NOHSC:1003) (1995);

• Occupational Health & Safety Act (2004);

• Occupational Health Safety Regulations (2007); and

• State Environment Protection Policy, Control of Noise from Commerce, Industry and Trade, No. N-1 (1989).

6 RESPONSIBILITIES

6.1 Tenant We understand that the site will continue use as a rifle range and all activities onsite will be administered by the Castlemaine Rifle Club. Although the site is owned by Mount Alexander Shire Council, the rifle club leases the land under a 99 year lease and that legally, they are responsible for the activities onsite. For the purpose of this EMP, the Castlemaine Rifle Club will be referred to as the site tenant. Under this document the tenant of the site has the following responsibilities:

• oversee actions taken by any contractor or site visitor post capping development;

• conduct site inductions including environmental management inductions for any people who may potentially come into contact with impacted soil;

211097_EMP.doc 8

• ensure all contractors and subcontractors comply with this EMP;

• ensuring that the requirements of this EMP are fully implemented, and in particular, that environmental management requirements are not subordinate to other site activities;

• for any financial liability in relation to ongoing maintenance, repair and/or management works on the site;

• respond to the directions of any delegated authority with respect to matters relating to contaminated soil. This may include exclusion zones whilst works are being undertaken, or the allowance for monitoring devices to measure air quality; and

• not personally undertaking any works which may cause contaminated soil to be disturbed.

6.2 Environmental consultant It is recommended that the environmental consultant engaged for this project is suitably experience; and also a member of the Australian Contaminated Land Consultants Association (ACLCA). The environmental consultant has the following responsibilities under this EMP:

• prepare this EMP for the site tenant;

• provide necessary training to all relevant personnel on project environmental matters (if required);

• liaise with the site tenant on an ‘as needed’ basis relating to environmental management issues; and

• conduct quarterly monitoring site inspections for one year, post-completion.

6.3 Subcontractors If maintenance works are to be conducted onsite (post capping works) appropriately qualified subcontractors will need to be used. All subcontractors will be responsible for:

• reporting any non-conformances or breaches of the EMP;

• ensuring any unsafe practices or incidents are brought to the attention of the tenant;

• completing quality work in a safe and environmentally responsible manner; and

• conforming to all site instructions and directions. Detailed procedures relating to environmental management are presented in the following sections.

7 ENVIRONMENTAL TRAINING

7.1 Qualifications All personnel directly involved in environmental management will be appropriately trained to undertake the tasks of the position to which they are appointed.

211097_EMP.doc 9

7.2 Training programs Those elements of the EMP which directly relate to the work to be carried out by the person or persons being inducted will be covered as part of their induction. Records will detail the attendees and content of the induction/training.

7.2.1 Competency and training Any workers operating plant or equipment onsite must be experienced in the operation of the plant and meet minimum competency levels. Proof of training or assessment cards must be provided on request.

7.2.2 Site induction All personnel employed onsite to undertake works which may disturb the cap or the impacted sands below will be required to participate in an Environmental Management induction to be conducted by the site tenant. The purpose of the Environmental Management section of the induction will be to:

• introduce the EMP;

• introduce the contaminants of potential concern (CoPC) and their distribution and potential exposure (primarily dermal soil contact);

• highlight the environmental controls to be implemented;

• discuss the applicable personal protection equipment (PPE); and

• other site management requirements.

8 DOCUMENTATION AND RECORDS Environmental management records will include the following:

• EMP (this document), method statements, Safe Work Method Statements (SWMS), procedures;

• changes to the EMP, method statements, SWM’s, procedures;

• environmental reports and correspondence;

• approvals, certification and licences issued by statutory authorities;

• specialist consultant monitoring reports;

• soil and industrial waste records including material tracking information and Waste Transport Certificates (if required).

9 QUARTERLY MONITORING The Environment Improvement Plan (EIP) specifies that ongoing monitoring is to occur at the site after the completion of capping works. Specifically the EIP specifies that: “Upon practical completion of the work and handover of the site to the Castlemaine Rifle Club ongoing monitoring of the finished surface will be required at regular intervals. It shall be the responsibility of the Contractor to ensure this monitoring is undertaken at three

211097_EMP.doc 10

monthly intervals during the first year after completion of construction. The monitoring shall entail a visual inspection of the cap surface, the drains associated with the storm water diversion system and where any runoff flows into the creek, for signs of erosion.” These quarterly cap monitoring inspections will be conducted by the Environmental Consultant and include site photographs and a brief letter report detailing the cap’s status at the time of the inspection. To aid in conducting the site inspections we have developed a check list (Appendix A) to be filled out during walkovers. This check list will ensure that subsequent inspections assess the cap in the same manner to maintain consistency.

10 ENVIRONMENTAL CONTROL PROCEDURES This part of the EMP outlines the objectives, strategies and control actions for any intrusive works onsite and their related impacts. It also summarises the environmental aspects to be addressed during the works. It must be noted that all contractors to undertake works onsite must abide by these procedures.

10.1 Soil control The objective is to provide a framework for addressing soil contamination issues during any intrusive site maintenance works, by providing information on the hazards and general procedures for disposal and handling of contaminated soil. The controls incorporated in any site works will be based on the following primary soil management measures:

• confining soil disturbance to as small an area as possible;

• placing impacted soil back into the excavation in the same order it was removed, and ensuring the capping material is re-compacted to a minimum Dry Density Ratio of 95% standard compactive effort. The top 150mm is to remain non-compacted to serve as topsoil;

• ensuring that workers handling potentially impacted soils wear appropriate PPE including steel capped boots, coveralls and gloves (Riggers are likely to be acceptable where only minor potential for soil contact exists);

• appointing an Environmental Consultant to collect appropriate soil samples for laboratory analysis and classification according to Victorian EPA IWRG621 if soil is to be disposed of offsite; and

• ensuring offsite disposal of soil complies with all relevant EPA Victoria regulations.

10.1.1 Earthworks Any earthworks to be undertaken on the capped area are likely to be confined to the excavation of service trenches or alterations to the firing mounds. The procedures for material handling are:

• if the classification of the soil is unknown, have it categorised in accordance with IWRG 621 and IWRG 702 guidelines. This will include the provision of a classification letter from the Environmental Consultant, identifying the category of soil to be transported; and

211097_EMP.doc 11

• following the provision of a classification letter by the Environmental Consultant identifying the category of soil to be transported, dispose of material to an appropriately licensed landfill using EPA approved trucks with Waste Transport Certificates.

In accordance with IWRG 621 guidelines materials to be excavated and disposed of fall into the following categories:

• ‘Fill’ which can be reused onsite;

• ‘Category C Waste’ (Contaminated Soil) will be disposed at a licensed landfill using EPA Waste Transport Certificates;

• ‘Category B waste’ (Contaminated Soil) will be disposed at a licensed landfill using EPA Waste Transport Certificates;

• ‘Category A Waste’ (Contaminated Soil) will require treatment onsite until CoPC classify the soil as Category B Waste or below. Following this treatment the material can be disposed of at a licensed landfill using EPA Waste Transport Certificates. Offsite treatment may also be possible at an authorised depot;

• concrete, wood, and metal will be recycled where possible; and

• solid inert waste (rubble not suitable to recycle) will be disposed to a suitable landfill.

10.1.2 Backfilling excavations In the event that excavation voids require reinstatement onsite, any material proposed for backfilling will need to be deemed suitable for use onsite in accordance with IWRG 621 and NEPM health based investigation levels. Additionally, it must be ensured that the material is aesthetically suitable and not odorous or visibly offensive. Furthermore in accordance with the EIP (2010) soil to be used to reinstate the cap must comply with the Unified Soil Classification System:

• SC Clayey SAND; and

• CL CLAY, Sandy CLAY, Silty CLAY This material shall comply with the following:

• maximum particle size 50 mm (as per AS 1289.3.6.1);

• greater than 90% passing 6 mm sieve (as per AS 1289.3.6.1 and/or AS 1289.3.6.2);

• fines content of between 30% and 50% (as per AS 1289.3.6.1 and/or AS 1289.3.6.2);

• liquid limit (of fines content) less than 30% (as per AS 1289.3.1.1 or AS 1289.3.1.2);

• permeability less than 1 x 10-8 m/s, compacted to 95% standard compactive effort (as per AS 1289.6.7.1 or AS 1289.6.7.2);

• Emerson class number of 6, 7 or 8 (as per AS 1289.3.8.1); and

• less than 1% organic material (as per AS 1289.4.1.1).

3.3 Material tracking Due to the known impacted nature of the capped soil, any soil leaving the site must be classified in accordance with IWRG 621 and IWRG 702 guidelines. If classified as ‘Category C waste’ or above the soil must be transported and disposed in accordance with VIC EPA, Industrial Waste Resource Guidelines (2009). This will include disposal to an appropriately licensed landfill and the use of waste transport certificates. Documentation demonstrating

211097_EMP.doc 12

the soil classification needs to be forwarded to the landfill prior to transporting the material, to ensure it can accept this form of waste under its license conditions. Other material going off site will need to be tracked by logging truck departures from the site. Transport sheets and delivery/receipt dockets will be collated, and a summary of all dockets and loads prepared for both incoming and outgoing material. It is the responsibility of the developer and Managing Contractor/Builder to ensure that this information is available. The Environmental Consultant will receive a copy of the summary, and may carry out audits to ensure the reliability of the procedure. Accurate records are to be kept for the purpose of the liability management during any intrusive works. Information to be recorded includes:

• source area (excavation area);

• volume of material;

• type of material (fill material or natural material, clay or siltstone, visible impacts, rubble or odour etc.);

• transportation method (site dump trucks; excavator etc); and

• re-use purpose and location onsite.

11 HEALTH AND SAFETY Earthworks have the potential to create a hazardous or unhealthy environment for workers, specifically through the generation of dust because of the presence of chemicals of concern. There are some additional health and safety aspects that need to be considered when handling contaminated soil. These control measures are as follows:

• when coming into contact with soil, contractors should wear suitable PPE including:

o chemical resistant gloves;

o fully enclosed boots; and

o overalls or full length pants and long sleeve shirts to cover exposed skin.

• additional optional PPE should available at the site upon request, including:

o eye goggles or glasses; and

o half face respirators with P2 filters or P2 dust masks if dust is being generated, or odorous material is continually encountered.

• wash hands thoroughly prior to eating, smoking or touching exposed skin after coming into contact with soil.

Occupational health and safety information will be included, in the site induction which is required for all people entering the site.

211097_EMP.doc 13

11.1 Waste management The approach will be to apply the waste hierarchy outlined in the Environment Protection Act (1970). The hierarchy is:

• avoidance;

• reuse;

• recycling;

• recovery of energy;

• treatment;

• containment; and

• disposal. Once it has been determined that a waste stream cannot be avoided, reused, recycled or have any other higher hierarchy options, it must be appropriately characterised prior to disposal (IWRG 621, 2009). Reducing the production and disposal of waste during the project can bring about significant economic benefits to the company, as well as meeting ever increasing community expectations for companies to act in an environmentally responsible manner. The following sections outline some options for reducing the production of waste.

11.1.1 Waste Classification Any proposed intrusive works may generate waste materials with some of them representing a potential risk to human health or the environment. All waste generated during intrusive works will require management in accordance with EPA and Worksafe Guidelines with specific instructions developed for disposal of any prescribed wastes. The VIC EPA Industrial Waste Resource Guidelines (IWRG) 621 Soil Hazard Categorisation & Management (2009), gives an overview of the types of wastes, their descriptions, management options and other associated EPA requirements. All prescribed wastes generated or found during the project must be transported with a Waste Transport Certificate in accordance with IWRG 821.1 Waste Transport Certificates (2009). A series of code numbers are assigned to different types of waste and can be found in IWRG 822.2 Waste Codes (2010). These code numbers will be required when completing the EPA certificate(s) for disposing of liquid or solid prescribed wastes.

11.2 Air quality Satisfactory air quality must be maintained by minimising the impact of air pollution generated by any intrusive works. As such, action must be taken by contractors to minimise and monitor the exposure to any dust generated by construction workers and other site users.

11.2.1 Dust control The mitigation measures proposed for this project include:

• limiting the total area of soil exposed to the weather at any one time;

• hand spraying exposed surfaces with recycled water (if necessary);

211097_EMP.doc 14

• covering stockpiles of excavated soil (if any) with tarpaulins while awaiting classification and offsite disposal;

• cessation of operations on high wind days at the discretion of the Tenant or Environmental Consultant; and

• if dust is noted at levels which are disturbing workers, P2 dust masks of half/full face respirators with P2 filters must be work.

11.2.2 Dust monitoring Observations on dust generation will be made on a continuous basis by the subcontractor and/or tenant who will restrict or stop site works if conditions become unsatisfactory.

11.3 Water quality The objective is to minimise the impact of activities on stormwater runoff into the nearby creek. The control strategies will be based on control of construction generated water by managing the amount of potentially contaminating sediment and surface water leaving the site during maintenance works.

11.3.1 Stormwater and sediment control Prior to the commencement of intrusive work, the following stormwater and sediment controls may need to be installed:

• installation of a silt fence along the down gradient boundary of any areas of the site being worked;

• silt fences or sandbag barriers to all stormwater pits within 20 metres of the site; and

• ongoing maintenance of existing sediment traps and silt fences.

11.4 Soil management Should any soil require off-site disposal during any of the above activities, an appropriately qualified Environmental Consultant (ACLCA member) will be required to classify the material in accordance with Victorian EPA Industrial Waste Resource Guideline (IWRG) 621, Soil Hazard Categorization & Management (2009) and IWRG 702, Soil Sampling (2009) guidelines.

ENVIRONMENTAL EARTH SCIENCES GENERAL LIMITATIONS Scope of services The work presented in this report is Environmental Earth Sciences response to the specific scope of works requested by, planned with and approved by the client. It cannot be relied on by any other third party for any purpose except with our prior written consent. Client may distribute this report to other parties and in doing so warrants that the report is suitable for the purpose it was intended for. However, any party wishing to rely on this report should contact us to determine the suitability of this report for their specific purpose. Data should not be separated from the report A report is provided inclusive of all documentation sections, limitations, tables, figures and appendices and should not be provided or copied in part without all supporting documentation for any reason, because misinterpretation may occur. Subsurface conditions change Understanding an environmental study will reduce exposure to the risk of the presence of contaminated soil and or groundwater. However, contaminants may be present in areas that were not investigated, or may migrate to other areas. Analysis cannot cover every type of contaminant that could possibly be present. When combined with field observations, field measurements and professional judgement, this approach increases the probability of identifying contaminated soil and or groundwater. Under no circumstances can it be considered that these findings represent the actual condition of the site at all points. Environmental studies identify actual sub-surface conditions only at those points where samples are taken, when they are taken. Actual conditions between sampling locations differ from those inferred because no professional, no matter how qualified, and no sub-surface exploration program, no matter how comprehensive, can reveal what is hidden below the ground surface. The actual interface between materials may be far more gradual or abrupt than an assessment indicates. Actual conditions in areas not sampled may differ from that predicted. Nothing can be done to prevent the unanticipated. However, steps can be taken to help minimize the impact. For this reason, site owners should retain our services. Problems with interpretation by others Advice and interpretation is provided on the basis that subsequent work will be undertaken by Environmental Earth Sciences VIC. This will identify variances, maintain consistency in how data is interpreted, conduct additional tests that may be necessary and recommend solutions to problems encountered on site. Other parties may misinterpret our work and we cannot be responsible for how the information in this report is used. If further data is collected or comes to light we reserve the right to alter their conclusions. Obtain regulatory approval The investigation and remediation of contaminated sites is a field in which legislation and interpretation of legislation is changing rapidly. Our interpretation of the investigation findings should not be taken to be that of any other party. When approval from a statutory authority is required for a project, that approval should be directly sought by the client. Limit of liability This study has been carried out to a particular scope of works at a specified site and should not be used for any other purpose. This report is provided on the condition that Environmental Earth Sciences VIC disclaims all liability to any person or entity other than the client in respect of anything done or omitted to be done and of the consequence of anything done or omitted to be done by any such person in reliance, whether in whole or in part, on the contents of this report. Furthermore, Environmental Earth Sciences VIC disclaims all liability in respect of anything done or omitted to be done and of the consequence of anything done or omitted to be done by the client, or any such person in reliance, whether in whole or any part of the contents of this report of all matters not stated in the brief outlined in Environmental Earth Sciences VIC’s proposal number and according to Environmental Earth Sciences general terms and conditions and special terms and conditions for contaminated sites. To the maximum extent permitted by law, we exclude all liability of whatever nature, whether in contract, tort or otherwise, for the acts, omissions or default, whether negligent or otherwise for any loss or damage whatsoever that may arise in any way in connection with the supply of services.
