1 Introduction
1.1 Background
RPS Planning and Development (RPS) have been commissioned by AWE plc to produce a Remediation Specification for the Pingewood Gate development area, which is part of the proposed Project Mensa Facility Development at AWE Burghfield (AWE (B)). An overarching Remediation Method Statement (RMS) for the Project Mensa Facility Development has already been published by RPS for the wider Mensa Application Site area (Ref. 1).
Project Mensa is part of the Site Development Strategy Plan (SDSP) for AWE Aldermaston and AWE Burghfield, involving refurbishment and replacement of facilities constructed in the 1950s and 1960s. The Mensa Facility Development project will be undertaken at AWE Burghfield, with part of the project involving the redevelopment of land near the Pingewood Gate in the north-east corner of the site. It is proposed that a new vehicle inspection and access point and the Primary Intake Substation be constructed in the Pingewood Gate area. The long term plan is for the vehicle inspection area to be replaced with soft landscaping once the Mensa project construction has been completed.
The Mensa Application Site area is shown on Drawing JER3996-001 and includes temporary areas to be used during the construction of the Main Mensa Development. For the purposes of this Specification, the Pingewood Gate area is delineated on Drawing JER3996-PG-005 and pertinent features referenced in this Specification are provided on Drawing JER3996-PG-012.
1.2 Report Scope
Numerous site investigations and land quality reports have been undertaken across the site to identify ground contamination, and following assessment and characterisation, a number of risks from shallow soil contamination have been identified in the Pingewood Gate development area.
A Summary of the identified risks and recommendations to mitigate these within Pingewood Gate development area are outlined in the Mensa Ground Conditions Technical Report (Ref. 3) (GCTR) and in the Pingewood Gate
RPS Planning & Development 1 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
Interpretative Report (Ref 4). Reference should be made to these reports for more detail, but pertinent risks can be summarised as:
Encountering previously unidentified contaminants (including Asbestos Containing Materials (ACMs)) causing a risk to construction workers and future site users;
The potential for a source of Trichloroethene (TCE) contamination in shallow soils associated with the former 10A buildings.
Identified hotspots of lead contaminated soils in shallow soils at two locations; and
Potential for previously unidentified exploded ordnance causing a risk to construction workers and future site users.
In addition chemical concentrations of certain contaminants above the laboratory testing limits of detection have been encountered in groundwater in the vicinity. Concentrations identified are not considered to pose a potential risk to local groundwaters, abstractions or surface waters, however, assurance monitoring of groundwater is to be undertaken prior, during and post the Pingewood Gate construction phase as part of the ongoing groundwater assurance monitoring programme for the main Mensa development.
1.3 Remediation Objectives
This Remediation Specification has therefore been developed to outline Contractor requirements to manage or mitigate contamination risks during the development of the Pingewood Gate, including:
1. Providing appropriate methodologies on the identification, delineation, assessment and remediation of known or previously unidentified contamination, encountered during construction
2. Outlining procedures to protect construction workers, AWE staff and site visitors and the general public from contaminants during construction;
3. Providing requirements for remediation verification to demonstrate that remedial targets and objectives have been met (Remediation Verification Plan); and,
RPS Planning & Development 2 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
4. Identifying requirements for remediation supervision or independent inspection of contamination or remediation by the AWE Appointed Environmental Consultant during the construction works;
5. Requirements for appropriate characterisation and sentencing of contaminated soils for off site disposal or retention on site, as required;
6. Protocols for material handling, stockpiling and waste management procedures for off site disposal;
7. Defining monitoring wells which need to be protected during the Pingewood Gate construction phase to maintain the ongoing site wide groundwater assurance monitoring programme;
8. Outlining requirements for record keeping and specific documentation necessary for validating all the above to allow the independent production of a Verification Report.

2 Summary Site Setting
2.1 Introduction
This section of the report summarises the current land use across Pingewood Gate area and makes reference to additional background information used to characterise the environmental site setting.
2.2 Site Location and Description
2.2.1 General Description of the Pingewood Gate Area The Pingewood Gate area comprises a mixture of hardstanding, buildings and landscaped grassed areas. The hardstanding comprises car parking, storage compounds and roads. The buildings and their former uses are:
10.G.7 – formerly used as an office and compound for the gardening contractor (now demolished);
10.A.30 – storage for the auxiliary fire engine (now demolished);
10.A.31 – security station for Pingewood Gate; and
10.A.18C (and associated structures) – storage compound for gas cylinders and scrap metal (now demolished).
There are also a number of former building footprints in the southern part of the site area that have recently been demolished. These areas are now covered with levelled crushed concrete aggregate.
An area referred to as the Former Site Tip is included within the central part of the site. The Former Site Tip comprises a grassed undulating mound which is in some places up to 4m higher than the surrounding land. It contains infill associated with the tipping of demolition and construction materials (which include significant asbestos contaminated material) into a former railway cutting. To facilitate the development of the new Primary Intake Substation and associated services and infrastructure, this Former Site Tip area will be remediated and capped under a separate pre-enabling works Contract for which a separate remediation Specification is being produced by RPS (Former Site Tip Remediation Specification [in production], Ref. 2).
RPS Planning & Development 4 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
Notwithstanding, there remains a potential for shallow contamination to be encountered elsewhere during the development of the remainder of this Pingewood Gate Access/Egress site area.
2.2.2 Environmental Setting
For more information of the site and its surrounds, the regional geology, hydrogeology and hydrology etc. and background information on ground conditions from previous ground investigations, reference should be made to the Pingewood Gate Desk Study Report (Ref. 5) and the Factual and Interpretive Ground Investigation Reports for Pingewood Gate (Ref 12 and Ref 4).

3 Remediation Specification
3.1 Introduction
This Remediation Specification outlines procedures which the Contractor shall adopt in dealing with known and potential land contamination issues which may arise during the Pingewood Gate Access/Egress enabling works contract, and outlines:
1. General procedures to protect construction workers, AWE staff and site visitors and the general public from contaminants during construction;
2. Measures for dealing with asbestos contamination, controls and disposal measures;
3. Appropriate methodologies on the identification, delineation, assessment and remediation of known or previously unidentified contamination, encountered during construction;
4. Similar methodologies for the identification and assessment of trichloroethene contamination in soils where suspected.
5. Requirements for further characterisation of the identified lead contamination in soils;
6. Requirements for appropriate characterisation and sentencing of contaminated soils for off site disposal and retention on site including protocols for material handling, stockpiling and waste management procedures for off site disposal;
7. Procedures to be followed to meet the requirements of the UXO Safety Management System in place by AWE; and,
8. Defines monitoring wells which need to be protected during the Pingewood Gate construction phase to maintain the ongoing site wide groundwater assurance monitoring programme;
The Specification also identifies requirements for remediation supervision or independent inspection of contamination or remediation by the AWE Appointed Environmental Consultant during the construction works.
RPS Planning & Development 6 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
It also provides requirements for remediation verification to demonstrate that remedial targets and objectives have been met and outlines requirements of the contractor for record keeping and specific documentation necessary for validating all the above to facilitate the production of an independent Verification Report;
A separate Remediation Specification is being produced for dealing with known soil contamination within the Former Site Tip (Ref 2). This area is to be remediated and capped under a separate prior contract, hence is discussed no further in this Specification.
3.2 General Procedures During Excavations in Potentially Contaminated Soils
The Contractor shall take account of the health and safety measures detailed in the following section to minimise potential risks to construction workers, AWE staff and the general public, together with nuisance issues, during the construction / remedial works. A Safe System of Work (SSoW) shall be designed and implemented by the Contractor and must incorporate:
Works will be monitored by the AWE PM or AWE Appointed Environmental Consultant, as required;
Should stockpiling of material be necessary, they will be designated via markers to categorise them showing whether they are clean or dirty;
Materials placed on stockpiles must be stored such that cross- contamination from dust dispersal, run-off from rainfall and contamination of underlying clean soils is prevented;
Locations of stockpiles will be recorded and a schedule of stockpiles maintained and regularly updated;
Where materials are disposed of off-site to a licensed waste management facility, under the Duty of Care Regulations, the Contractor shall keep a schedule of chain of custody and consignment notes, which will include waste transfer ticket number (including waste classification), vehicle registration, destination landfill and weight recorded by the weighbridge at the landfill; and
RPS Planning & Development 7 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
Following completion of the works a copy of the disposal record shall be provided to the AWE PM as part of the Verification Report (Section 4).
The following procedures shall be adopted to protect site personnel, which will be supplemented by Personal Protective Equipment (PPE) and additional SSoWs as necessary.
Provision of covers over any skips of waste to reduce dust and contact with the waste;
Minimising dust from groundworks by use of damping down equipment;
Wheel wash/lorry wash for use by all vehicles leaving the development area during the groundworks phase;
Provision of welfare facilities to allow washing prior to use of mess facilities and leaving site for the day. Facilities also to allow for changing out of PPE.
The following PPE is to be used, which will be maintained and worn:
Hard hats, boots, gloves, safety glasses and high visibility vests;
Disposable overalls to be used as necessary;
P3 filter masks with particulate filters to be made available to staff and worn as required.
Although considered unlikely given the nature of the works, additional PPE may also be required during the course of siteworks and therefore should be made available where considered necessary (for example, ear defenders, vapour masks or Respiratory Protective Equipment (RPE))
The SSoW shall include reference to the Explosive and Ordnance (UXO) Safety Management system as described in Section 3.8
3.3 Asbestos Control and Disposal Measures
There is potential for asbestos to be encountered and disturbed during the development works. A SSoW shall be designed and adopted by the appointed Contractor and will include the production of all risk assessments and method
RPS Planning & Development 8 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
statements. The Contractor shall implement the following measures during earthworks where asbestos contamination is suspected:
Use of appropriate RPE/PPE for site personnel;
Covering and containment of stockpiled asbestos contaminated soils;
Segregation and/or hand picking of asbestos contaminated soils where deemed necessary and practicable; and
Inspection by the AWE Appointed Environmental Consultant as required, to confirm no residual asbestos containing materials remain.
If a substantial amount of previously unidentified ACMs are encountered during excavations, the Contractor will implement additional measures to include:
Development of a Safe System of Work;
Establishment of a decontamination unit;
Damping down of excavations and earthworks; and
Wheel wash/lorry wash for use by all vehicles leaving the development area during the groundworks phase.
Any encountered asbestos contaminated soils (or other ACMs) will require handling by a licensed contractor and materials disposal off site must be sent to a licensed management facility.
Inspections by the AWE Appointed Environmental Consultant, experienced in the identification of asbestos, should be undertaken to verify the asbestos contaminated soils have been removed. The general procedures outlined in Sections 3.2 & 3.4 will also apply should asbestos be encountered.
The remedial goals for dealing with asbestos contaminated soils will be:
No visual evidence or laboratory identified asbestos contamination within 0.3m of final formation level within areas of soft landscaping;
No visual evidence or laboratory identified asbestos contamination at the final soil formation level within the building footprint or areas of hardstanding.
RPS Planning & Development 9 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
3.4 Procedures for Encountering Unidentified Contamination
It is anticipated that given the previous investigation coverage and sampling, if any soil contamination is encountered, it is likely to be limited in extent and either dismissed through minimal risk assessment or through remediation by way of source removal.
If previously unidentified gross chemical contamination is encountered during the construction phase, works must be immediately stopped and the AWE Appointed Environmental Consultant contacted to undertake an inspection of the contamination. Provision for such occurrences is to be detailed within the SSoW.
As a minimum, the following shall be established by the Contractor prior to construction works commencing:
1. Development of a procedure that will be followed if previously unidentified asbestos, chemical contamination or suspected explosives residues are identified during earthworks; and
2. Ensuring ground workers have completed a health and safety risk assessment, developed a SSoW and have demonstrated that adequate control measures are put in place to manage the potential for soil contamination.
The Contractor will ensure that the following is adhered to in relation to encountering previously unidentified chemical contamination and/or asbestos during construction works.
1. Ensure personnel involved in the earthworks are briefed on the likely nature and type of soils that could indicate the presence of contamination (e.g. discolouration, oils, odours, asbestos, ash and clinker materials);
2. If such material is encountered, the AWE Appointed Environmental Consultant should be immediately contacted to inspect the material;
3. If material is identified as potentially contaminated, the extent should be delineated and samples collected for field and / or laboratory analysis as deemed appropriate by the AWE Appointed Environmental Consultant;
RPS Planning & Development 10 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
4. Analytical results shall be compared to Site Specific Target Levels (SSTLs) generated within the Interpretative Reports (referenced in Section 5). Once the contamination has been sufficiently delineated, comparison with the relevant SSTLs applicable to either an indoor or outdoor scenario, shall be used in conjunction with the development layout plan. Should a hotspot of contamination fall across the building footprint boundary the most conservative SSTLs should be utilised or alternatively advice sought from the AWE Appointed Environmental Consultant. (Note that new SSTLs may need to be derived if not already generated for specific chemical determinants); and
5. Concentrations above the applicable SSTLs will require either further detailed risk assessment or remediation as advised by the AWE Appointed Environmental Consultant. Any further risk assessment or remedial action shall be agreed with the Local Planning Authority. Based on available information, it is anticipated that should remediation be the most applicable course of action, source removal of localised “hot spots” is likely to be the most appropriate strategy, supported by verification testing. The remediation verification of any contamination sources identified during redevelopment will include:
Delineation of the extent of chemical contamination and verification by inspection by AWE Appointed Environmental Consultant and laboratory analysis of soils appropriate to the type of contamination being removed.
Sentencing and disposal of contaminated materials off-site to a suitably licensed waste management facility;
Similarly, analysis of suspected asbestos containing materials encountered during redevelopment for an asbestos screen analysis; and
Disposal of encountered asbestos contaminated materials off-site to a suitably licensed landfill with appropriate chain of custody and consignment notes required under the Environmental Protection Act, Duty of Care Regulations. Contaminated waste soils shall be managed as outlined in Sections 3.7 & 4.3.
RPS Planning & Development 11 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
3.5 Potential TCE Impacted Soils
For construction works within the former Buildings 10A TCE contaminated area in the proposed southern car park, there may be greater potential for shallow soils to be present which have been impacted by trichloroethene as a definitive source has yet to be identified.
The AWE Appointed Environmental Consultant should be present during the groundworks phase in this area to regularly inspect excavations. In addition to a visual and olfactory inspection, a PID would be used to monitor potentially impacted soils.
Where significantly elevated concentrations of volatile vapours are recorded, and materials are identified as potentially contaminated, works must be immediately stopped and samples collected for field and / or laboratory analysis as deemed appropriate by the AWE Appointed Environmental Consultant.
Procedures as outlined in Section 3.4 shall then be adopted for the assessment, further delineation and or remediation of contaminated soils as advised by the AWE Appointed Environmental Consultant and subsequent validation testing.
3.6 Lead Contamination in Soils
From the most recent phase of ground investigation works (Ref. 4) significantly elevated concentrations of lead contamination have been identified in shallow soils at two locations within the site area.
• Borehole BHPG-002, 0.0 – 0.1mbgl, at a concentration of 6130 mg/kg; and
• Trial Pit TPPG-044, 0.0 – 1.0mbgl, at a concentration of >10,000 mg/kg.
It should be noted that both of these samples are currently being retested by the laboratory to confirm the validity of these results.
If these concentrations prove correct these hotspots will require further characterisation again following the procedure outlined in Section 3.4. Following further assessment, and or delineation, remediation of an area of
RPS Planning & Development 12 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
contaminated soils may be required as advised by the AWE Appointed Environmental Consultant, most likely by way of source removal by excavation and subsequent validation testing.
With lead in soils at these concentrations, the resulting waste soils are likely to require disposal as hazardous waste.
The Contractor shall provide all required documentation to satisfy the AWE Appointed Environmental Consultant that the lead hotspots have been suitably remediated.
3.7 General Waste Handling Arrangements
With regard to the general soil waste handling requirements the Contractor shall adhere to the following general requirements while handling waste soils:
Waste shall be stored and disposed of in accordance with AWE’s existing Corporate Safety Instructions (CSI1603, CSI1604 and CSI1701);
A Site Waste Management Plan should be prepared by the Contractor for AWE’s approval and then implemented
All waste shall be segregated in labelled, appropriate containers / areas;
Inert, Non hazardous and Hazardous wastes shall be segregated and not mixed;
Waste containers shall be located in a secure, controlled location;
All Contractors staff / personnel working within the enclave will be briefed on the waste management requirements and waste minimisation measures. Records will be kept of attendance;
Waste audits shall be completed periodically by the construction Contractor and AWE, the latter shall, as a minimum, be represented by the Assurance Environmental Department (AED) and the AWE PM;
If the Contractor requires any waste to be disposed of to a waste disposal facility, the Contractor shall inform the AWE PM in good time to allow an audit of the identified potential disposal facility;
RPS Planning & Development 13 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
No waste will be brought onto the AWE site from off-site sources; and
The Contractor shall be responsible for determining whether wastes are hazardous in line with WM2 (Ref. 34) and shall comply with both Hazardous Waste Regulations and Landfill Waste Regulations for disposal of waste to landfill.
3.8 Explosives and UXO Safety Management System
Although overall risk of encountering explosive residues and/or unexploded ordnance (UXO) is considered low across the Pingewood Gate site area, given the history of development of the site, AWE will have a UXO Safety Management System in place prior to works commencing. This will include a number of procedures to be followed should suspect materials be encountered.
This UXO safety management system will likely include:
Ordnance and explosive safety briefing to construction staff by an experienced Explosive Ordnance Engineer including the likely types of explosives and ordnance that could be encountered during the site construction works.
Procedures to follow should suspected explosive residues be identified.
Procedures to follow should buried unexploded ordnance be identified.
Should UXO or suspected UXO be encountered during the construction phase, works must be immediately stopped and the AWE PM immediately informed and a qualified Explosive Ordnance Disposal (EOD) Engineer contacted to undertake an inspection of the residue / ordnance.
3.9 Groundwater Assurance Monitoring Programme
A number of pre-existing monitoring wells are located across the Pingewood Gate development area at key locations (that is, within boreholes 1ABH3, BH101, BH102 and BHCMR009 across the northern part of the site, and boreholes 1ABH1, PH173, PH176, WS-TCE-04, WS-TCE-05, WS-TCE-06 WS- TCE-08 towards the south). Each of these wells are required to be serviceable throughout the construction phase, to ensure the ongoing assurance monitoring to determine the quality of shallow groundwater and the deeper aquifer.
RPS Planning & Development 14 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
Groundwater will be sampled by the AWE Appointed Environmental Consultant at regular intervals, prior to construction, during site development work and post construction. Therefore all existing monitoring boreholes listed above and indicated on Drawing Ref: JER3996-PG-012 must be protected and maintained by the Contractor to ensure their viability for the duration of the programme of assurance groundwater monitoring.
However, it is likely that a number of boreholes may be damaged or destroyed during the main construction works hence any monitoring boreholes which are rendered unserviceable as a result of construction will require replacement to maintain sufficient site coverage for the assurance monitoring.

4 Remediation Verification Report
4.1 Routine Documentation
In order to provide appropriate ‘lines of evidence’ to demonstrate to the Regulators that that appropriate remedial works have been undertaken for each specified area, various standard documentation will be required which will be common to many of the tasks as specified above. AWE will require documentary evidence from the Contractor to demonstrate remediation has been satisfactorily achieved, and be necessary for the compilation of the Remediation Verification Report, to be produced by AWE, on completion of the contract. The Contractor shall therefore ensure routine and rigorous record keeping for all key documentation.
Any remedial works, such as the removal of asbestos contaminated soils or chemically contaminated soils, waste disposal of materials off site or capping requirements shall be carefully documented by the Contractor. The routine documentation of the works to be carried out by the Contractor shall include, but not necessarily be limited to the following:
Daily record sheets detailing activities on the site;
Excavation records detailing the material in each excavation;
Excavation plans showing the dimensions and nature of each excavation together with any sampling locations;
Any locations where previously unidentified contaminated soils are encountered;
Details of any changes to any remedial works due to findings on the site such as previously unidentified contamination;
Stockpile plans showing the dimensions and nature of stockpiled material where appropriate;
As built drawings, construction drawings;
For Duty of Care, records of contaminated soil arisings detailing waste transfer ticket number, vehicle registration, landfill address and weight recorded at the landfill shall be provided by the Contractor.
RPS Planning & Development 16 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
The following sections outline other specific protocols and requirements necessary in order to demonstrate that remediation has been achieved in the production of a comprehensive post remediation Validation Report for the Pingewood Gate development area.
4.2 Remediation Verification Report
A final Remediation Verification Report will be prepared by the AWE Appointed Environmental Consultant and will detail any remedial works carried out by the Contractor. The Contractor shall therefore provide all information and documentation outlined in Section 4 in a timely manner.
The Remediation Verification Report will demonstrate the following were met during the works:
Any soils exhibiting visual evidence of asbestos containing materials and/or visual and olfactory evidence of chemical contamination not previously identified, including Asbestos Containing Materials (ACMs), have been inspected.
The extent of any contamination identified was delineated and verified by inspections by the AWE Appointed Environmental Consultant, and where necessary laboratory analysis of soils appropriate to the type of contamination was undertaken.
Any laboratory analysis of samples were undertaken using a UKAS accredited laboratory methodology and in the case of soil analysis MCERTS accreditation was also adopted;
Contamination has been characterised, delineated, risk assessed and/or remediated as necessary.
Verification sampling supervised by the AWE Appointed Environmental Consultant, to demonstrate soils remaining in the ground following removal of contamination are below the relevant SSTLs and do not pose a risk.
The source of the elevated lead contamination in soils has been characterised and remediated.
Materials or soils contaminated with asbestos or other waste soils were disposed of to a suitably licensed landfill facility with the appropriate
RPS Planning & Development 17 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
chain of custody and consignment notes required under the Environmental Protection Act, Duty of Care Regulations and AWE Corporate Safety Instruction CSI 1706;
Records of volumes of all waste removed, name of the disposal facility and copies of waste transfer notes;
Comment on whether any significant changes in groundwater quality were observed following groundwater monitoring results undertaken prior to, during and post construction, and whether remedial action was required.
The format and contents of the Verification Report shall be compiled using guidance provided in the Environment Agency’s Verification of Remediation of Land Contamination (Ref. 15).
4.3 Off Site Disposal of Waste
4.3.1 Site Waste Management Plan
The Contractor shall be required to work to a Site Waste Management Plan to meet the requirements of The Site Waste Management Plans Regulations 2008 (Ref. 16). During the works the Contractor shall seek to minimise waste being generated and recover and re-use wastes wherever possible. The Contractor shall provide AWE detailed information in volumes of waste generated and volumes of waste recovered.
A Data Quality Assurance (DQA) and Waste Characterisation Report (Ref. 17) is at the time of writing being prepared by RPS for the Pingewood Gate development area which will assist with anticipated waste classifications (due for completion January 2009).
4.3.2 Waste Transfer Notes
Under the Environmental Protection (Duty of Care) Regulations 1991, those responsible for producing or handling wastes have legal requirements placed upon them for the safe keeping, transport and subsequent recovery or disposal of wastes. Therefore as a minimum, the Contractor shall ensure that all waste leaving site must have a Waste Transfer Note and a copy of every Waste

6. Certificate number of registered waste carrier;
7. Waste management licence number of waste facility;
8. The name and addresses of any broker involved in the transfer; and
9. Signatures of both parties.
All Waste Transfer Notes shall be kept for a minimum of three years.
4.3.3 Hazardous Waste
Hazardous waste generated during the construction phase will require AWE plc to register with the Environment Agency that they intend to produce hazardous waste and comply with the Hazardous Waste Regulations. The AWE PM shall register the ‘premises code’ and provide the Contractor with these details.
The Contractor shall be responsible for record keeping of all hazardous waste materials removed from site. This record keeping shall include:
1. Maintaining records and registers of all hazardous waste removed from site. A consignment note must be completed to accompany hazardous waste that is removed from the site;
2. AWE shall obtain hazardous waste consignment numbers from the Environment Agency and the Contractor shall obtain from AWE a
RPS Planning & Development 19 AWE Burghfield January 2009 JER3996 Remediation Specification, Pingewood Gate
