4 1. INTRODUCTION This document is part of an Environmental Management Program that is designed to fulfil environmental conditions set for the project by the Minister for the Environment. The document has been prepared to fulfil Environmental Condition 4-1, subclause 18 to 24, detailing the procedures to manage the transport of contaminated soil to landfill. A Soil Management Plan (SMP) has previously been prepared, which identified and described the contamination status of the soil to be removed. ENV Australia has been commissioned by the Ministry for Planning and Infrastructure to develop this Transport Management Plan (TMP) detailing the approach to transportation and disposal of the contaminated material. Page 1

5 2. BACKGROUND 2.1 SITE DESCRIPTION AND HISTORY The site is situated approximately 5 km south of Fremantle and on approximately 51 ha of land. A variety of industries have operated within the project area, with none of them currently operating in the project area. 2.2 CONTAMINATION OVERVIEW There are 23 sites within the project area as shown on Figure 1. Many of these are vacant lots or reserves with a low potential for contamination due to localised dumping or air borne drift. The sites that contain more significant contamination are associated with industry that was previously operating on that site. Each site was individually assessed. Page 2

6 3. OBJECTIVES This Transport Management Plan (TMP) will detail how the waste material is to be handled and transported during the remediation phase. Specifically the TMP describes the procedures for the safe and effective removal, stockpiling, transport, characterisation and disposal of waste as well as a tracking system for recording the movements of contaminated soil for accountability purposes. The objective of the TMP is to provide sufficient detail to fulfil the requirements of the relevant Environmental Condition. The Transport Management Plan has been structured in response to the requirements of the condition which are as follows; Transport Management Plan types of waste materials; excavation and loading methods; controls on vehicles for the transport of wastes; types and roadworthiness of vehicles; the routes for transport of wastes, and the approvals from relevant authorities to use these routes; documentation and records of waste departures and destinations; and emergency response plan. Two separate procedures have been developed to fulfil these objectives: 1. Contaminated Soil Removal Procedure; and 2. Contaminated Soil Transport Procedure; 3.1 TYPES OF WASTES Soil contamination has been described in detail on a site by site basis within the SMP. An estimated 50,000 m 3 of soil has been identified as needing to be removed to achieve environmental objectives (Table 1). The majority of this contamination will be disposed to a Class 1 landfill, subject to acceptable leachate results. Less than 2,000 m 3 of soil will need to be disposed to a Class 3 landfill due to higher levels of contamination. The contamination on site is mainly associated with heavy metals with some smaller areas of hydrocarbon and organochlorine pesticide (OC) contamination. Page 3

7 Waste characterisation will be performed to ensure that contaminated material is suitable for disposal to landfill. The Contaminated Soil Removal Procedure (CSMP) will be used to manage the removal and characterisation of contaminated material. Table 1: Volume and Type of contaminated material at each site.

8 3.2 EXCAVATION AND LOADING METHODS Excavations and loading will be undertaken using conventional earthmoving vehicles in a manner that minimises dust generation. Care will be taken to ensure that different types of contaminated material are not blended together. The CSMP will be used to manage the excavation and loading of contaminated material, the CSMP will: Require dust control to be applied during excavation and loading; Require contaminated material to be stockpiled as close to the source of the material as possible; Ensure different classes of contaminated material are stockpiled separately; and Describe actions to ensure operators of earthmoving machinery are appropriately qualified. 3.3 VEHICLE CONTROLS Vehicles transporting contaminated material offsite will be managed in such a way to prevent dust and contaminated material from falling off trucks. The Contaminated Soil Tracking System (CSTS) will be used to control vehicles transporting contaminated material which will: Ensure that machinery/trucks are being operated by licensed personnel; Ensure that vehicles leaving site are washed down and loads are covered to prevent the spread of contaminated material ; Require vehicle inspections prior to leaving the site which will include logging of contents and destination; and Reporting of an incident and the associated management should also be provided to the DEP, Department of Health and relevant Local Authority. 3.4 ROADWORTHINESS OF VEHICLES The vehicles used on site will consist of trucks to cart contaminated and fill material and conventional earthmoving vehicles for the removal, infill and loading of contaminated and fill material. All vehicles that are used on site will be required to be roadworthy. Vehicle inspections will be performed prior to remedial works commencing Page 5

9 3.5 TRANSPORT ROUTES Contaminated material will be disposed to either Class 1 or Class 3 landfill sites. The landfill sites in closest proximity are Abercrombie Street in Postans for Class 1 material and Millar Road in Baldivis for Class 3 material. The proposed transport route to and from the Class 1 landfill facility at Postans will be: 1. South down Cockburn Road/ Rockingham Road for approximately 12 km to Thomas Rd; 2. East along Thomas Road for approximately 1.5 km to Abercrombie Road; and 3. North up Abercrombie Road to the landfill facility. The proposed transport route to and from the Class 3 landfill facility in Baldivis will be: 1. South down Cockburn Road/ Rockingham Road for approximately 13 km to Mandurah Road; 2. South down Mandurah Road for approximately 8 km to Millar Road; and 3. East along Millar Road to the landfill facility. The identified landfill facilities represent the closest sites. The final destinations will be selected by the successful remediation contractor. All routes will use main roads outside of residential areas. 3.6 DOCUMENTATION Waste departures and destinations will be documented and recorded. A contaminated soil tracking system will be used to: Record the contaminated material characteristics, including type, volume and class. Document the details of trucks carrying contaminated material, including the condition of the vehicle and time of departure. Detail the destination for the contaminated soil. Detail the mechanism for checking landfill receipts against documented vehicle movements to ensure that contaminated material has been disposed at the appropriate class of landfill. Page 6

10 3.7 EMERGENCY RESPONSE PLAN This emergency response plan details the corrective actions that will be undertaken should an unexpected situation arise. The procedure will ensure that any action that is taken is immediate and that the situation is quickly resolved. A review of the remediation process identified one probable emergency situation that could arise. This would involve a truck in an accident while transporting contaminated soil. Should this occur the following response will be initiated: Isolation of any spilt material using flagging tape and witches hats; Identify landfill contamination status using the log system information; Notification of the Environmental Supervisor and emergency regulatory authorities; Immediate clean up and transfer of spilt material into an alternative truck; and Review of accident details and therefore transport route to ensure that it is safe. To deal with emergency situations, all trucks will be required to carry a mobile phone, 2-way radio to base, first aid kit, shovel, witches hats and flagging tape, and appropriate personal protective equipment for handling the material.

11 4. CONTAMINATED SOIL REMOVAL PROCEDURE The Contaminated Soil Removal Procedure (CSRP) is designed to ensure that contaminated material is excavated, stockpiled and removed in an environmentally sound manner and that the material is appropriately characterised. 4.1 CONTROLS This procedure will be used to control the following tasks and items: Rate of excavation based on compliance to air quality, noise and vibration criteria; Excavation of waste; Characterisation of waste materials for disposal to landfill; Location of stockpiles; and Loading of waste. 4.2 ACTIONS The following actions are to be followed for the removal of contaminated material across the site: Environmental Supervisor will supervise where required remedial works occur; The extent of contamination will be surveyed and marked out prior to excavation; Stockpiles, exposed areas and areas requiring excavation will be wet down prior to work and when wind conditions dictate. Full details are provided in the Noise and Dust Management Plan (ENV, 2002); Machinery operating in the exclusion zones are to be thoroughly cleaned with a high pressure hose prior to leaving the zone; Soil will be stockpiled according to the nature and degree of contamination based on the contamination status identified in the SMP, stockpiles will be located on known soil contamination and on the lot from which it was excavated; Stockpiles will be managed to ensure that runoff is collected and does not contaminate clean material. Full details are available in the Stormwater Management Plan (ENV, 2002); All stockpile locations are to be inspected daily by the Remediation Contractor and at regular intervals by the Environmental Supervisor; Page 8

12 The Environmental Supervisor will sample stockpiled material to be removed off-site in accordance with the Guidelines for Acceptance of Solid Waste to Landfill (2001) and subject samples to ASLP testing; Results of ASLP tests will be compared, along with contaminant concentrations, to the appropriate criteria in Table 5 of the Guidelines for Acceptance of Solid Waste to Landfill (2001) to determine landfill for disposal; Any contaminated soil beneath stockpiles will be removed concurrently with stockpile removal; and Truck loads are to be within legal weight limits and covered. 4.3 MONITORING AND REPORTING The most important aspect of monitoring soil removal and handling is both nuisance and contaminated dust. Monitoring and corrective action regarding this issue is described in the NDMP. Routine random checks will be undertaken by the Environmental Supervisor of waste handling practices to ensure all details are being completed and that material is being relocated in conformance to this procedure. The Environmental Supervisor will oversee the remediation activities and will maintain an up to date logbook of complaints and incidents in the form of an Environmental Incident Report form and Public Complaints Register which are provided in the Site Remediation and Integration Plan (SRIP). 4.4 CORRECTIVE ACTIONS The following corrective actions may be implemented: If material does not comply with the Guidelines for Acceptance of Solid Waste to Landfil (2001), the waste will be treated with immobilisation agents to reduce waste leachability, tested, and then if in conformance disposed of to an appropriate landfill. Should contaminated material be accidentally placed on natural ground, the Remediation Contractor will be required to remove the contaminated material including the underlying 0.1 m of natural ground beneath the fill. The Environmental Supervisor will collect samples from the natural ground beneath the misplaced material and test for the relevant contaminants to ensure that levels are below the environmental criteria. Sampling frequency is to be performed in accordance with the DEP Contaminated Site Assessment Development of Sampling and Analysis Programs (2001); and Page 9

13 In the event that complaints and incidents are recorded or should monitoring show the need, action will be taken immediately with reporting/ notification to all parties within 48 hours. In addition, any lawful direction from regulatory authorities will trigger a review of remediation activities. Page 10

14 5. CONTAMINATED SOIL TRANSPORT PROCEDURE The objective of the Contaminated Soil Transport Procedure (CSTP) is to ensure that the material carted from the site is conducted in a safe and efficient manner. 5.1 CONTROLS This procedure will be used to control the following tasks and items: Controls on vehicles for the transport of wastes; Types and roadworthiness of vehicles; The transport routes for wastes removal, and the approvals from relevant authorities to use these routes; and Documentation and records of waste departures and destinations. This procedure describes the practices to be followed regarding the removal and transport of contaminated soil to landfill as well as outlining the transport routes. 5.2 ACTIONS The following actions are to be followed for the transport of contaminated material from site to disposal facilities: Contaminated material will be transported off-site once approval has been provided by the landfill operator and transport routes have been approved b y relevant authorities; All movement of contaminated soil to be recorded using the contaminated soil tracking system, which will consist of the following: A log sheet issued to all vehicles carting material off-site recording the source, vehicle registration, time, check of load condition, landfill destination and volume and nature of contaminated soil. An example of the log sheet is provided as Attachment 1; The log sheets will be in duplicate with the original retained by the landfill operator and the duplicate retained by the Remediation Contractor, once signed as being received by the landfill operator; A sequential number on the log system will be allocated to each truck movement carting contaminated soil; Inspection of each truck prior to leaving the site to ensure loads are secure, with the checklist provided on the log system; and Each log sheet is to be signed off by the Remediation Contractor s representative at the end of each working day. All off-site log sheets are to be Page 11

15 provided on a summary sheet once the original copy has been received back from the landfill operator. The Environmental Supervisor will conduct random inspections of the contaminated soil tracking system to ensure adherence to the procedure; Trucks are to be roadworthy and operated in accordance with the transport regulations; A speed limit of 40 kph will apply to all traffic on tracks and 10 kph for machinery operating off tracks; All trucks will be covered with tarpaulins to prevent dust emissions whilst in transit; Trucks to exit through a washdown pond and rumble strip to remove contaminated material adhering to tyres and wheels. This will be constructed of compacted crushed limestone with a sealed base to prevent leaching into the soil; Site exit and entry points will be monitored and when necessary will be swept down to remove built up material; Trucks will access the site via Cockburn Road; and The movement of trucks will be south along Cockburn Road along the route specified in section 3.5 depending on the class of landfill for disposal. 5.3 MONITORING AND REPORTING The most important aspect requiring monitoring is the potential generation of both nuisance and contaminated dust. Monitoring and corrective action regarding this issue is described in the NDMP. Routine checks will be undertaken by the Environmental Supervisor of waste handling practices to ensure all details are being completed and that material is being relocated in conformance to this procedure. The Environmental Supervisor will oversee the remediation activities and will maintain an up to date logbook of complaints and incidents in the form of an Environmental Incident Report form and Public Complaints Register which are provided in the SRIP. Page 12

16 5.4 CORRECTIVE ACTIONS The following corrective actions may be implemented: Contaminated material that has been spilt is to be recovered manually b y shovel for small quantities or with earthmoving machinery for large volumes; Minor traffic accidents are to be assessed and changes made to controls if applicable, major accidents causing injury are to be reported to both Worksafe and the Police; and In the event that complaints and incidents are recorded or should monitoring show the need, action will be taken immediately with reporting/ notification to all parties within 48 hours. In addition, any lawful direction from regulatory authorities will trigger a review of remediation activities. Page 13
