2 SITE LOCATION AND DESCRIPTION

2.1 Site Location

2.1.1 The site is located to the northeast of Corby town centre, Northamptonshire and is accessed off Pilot Road. The approximate centre of the site is at grid reference SP 490156, 289666. The site location map is presented as figure 1.

2.2 Site Description

2.2.1 The site is flat and level comprising tarmac road at the entrance and concrete hard standing surface throughout between industrial buildings. There are various buildings on site mainly consisting of steel portal frame structures with corrugated panel siding and roofs, supported by concrete foundations and brick walls. The buildings are used for office, storage areas and warehousing facilities.

2.2.2 The proposed development site is generally flat and level. A small concrete slab is located along the southern fence line and steel girders are present inside the fence protruding vertically from the surface along the northern boundary and in the south west corner of the site. The purpose of the steel girders is unknown, but may have been used as a vehicle barrier.

2.2.3 There are no overhead services within the site boundary, however overhead power lines are located beyond the southern, western and northern site boundary. Surface water drainage gullies and manhole covers, and also scarring on the surface were visible where services may be present.

2.2.4 A buried drainage tank is located approximately centrally within the area of proposed development. The services locations plans are presented in Appendix 1.

2.3 Proposed Development

2.3.1 The proposed development is for the construction of a concrete slab with storage bays to be used for the storage, handling and transfer of glass. The area to be developed is located in the southwest corner of the main MRF site.

2.3.2 The development site comprises an area of aggregate hard standing and is currently used for the storage area for various materials, storage containers and plant. Steel fencing is present along the south and west perimeters of the site in the area of the proposed development area.

3 GROUND INVESTIGATION

3.1 Description of Fieldwork

3.1.1 Site works commenced on 16th March and were completed on 17th March. The works consisted of two light cable percussion boreholes (BH101 and BH102), six machine-excavated trial pits (TP201 to TP206), four hand held dynamic cone penetrometer tests (DCP301 to DCP304) and two 300mm diameter plate bearing tests (PB1 and PB2). The approximate locations of the boreholes are shown on figure 2.

3.1.2 Caulmert directly appointed Discovery CE Ltd (DCE) to complete the investigation works. An Engineer from DCE attended site to set out the exploratory hole locations, check for buried services using a cable avoidance tool, log the arisings from the boreholes and trial pits and complete dynamic cone penetrometer testing at selected locations. Statutory services plans were supplied by Viridor. A geotechnical engineer from Caulmert attended site and supervised the works on a full-time basis and instructed the collection of samples for laboratory chemical and geotechnical testing.

3.2 Cable Percussion Boreholes

3.2.1 The boreholes were constructed using a Pilcon 1500 cable percussion rig and progressed using 150mm diameter tools and casing and were sunk to intercept the natural superficial deposits. The depths to the base of the exploratory holes are given in Table 3.1.

3.2.2 Hand excavated pits were completed at each borehole location to depths of 1.0 mBGL to check for the presence of services prior to starting the drilling. No services were encountered in any of the exploratory holes. The borehole logs are presented in Appendix

3.3 Standard Penetration Testing

3.3.1 Standard penetration testing (SPT) was undertaken in each borehole and the ‘N’ value recorded for each test completed, the results of which are presented on the borehole logs in Appendix 2. A total of thirteen SPTs were completed, six in borehole BH101 and seven in borehole BH102. A summary table and plots of the SPT ‘N’ values versus depth are presented in Appendix 3.

Caulmert Ltd 2010.7.VWM.DEO.PAC 3 April 2015 Viridor Waste Management Ltd Concrete Slab for Glass Handling, Storage and Transfer Factual Ground Investigation Report

3.4 Trial Pitting

3.4.1 The trial pits were excavated using a JCB 3CX mechanical wheeled backhoe loader to intercept the natural superficial deposits. The depths to the base of the trial pits are given in Table 3.2 and presented on the logs in Appendix 4. All trial pits terminated in the Northampton Sand Formation.

3.4.2 Where cohesive (clay) strata were encountered in the trial pits a hand shear vane was used to determine the undrained shear strength on the disturbed arisings. The results are presented on the logs in Appendix 4.

3.5 Sampling

3.5.1 Bulk disturbed and small disturbed samples of the strata were taken from the depths shown on the borehole and trial pit logs, details of which are presented in Appendix 2. All samples for geotechnical testing were sent to Celtest Ltd laboratory, Bangor, North Wales, where selected samples were tested. Small disturbed samples were taken and stored in airtight sealed containers to maintain their natural moisture content, and these were also used to determine plasticity index.

3.5.2 Samples selected for chemical testing from the boreholes and trial pits were sent for testing to SAL Laboratories, Trafford, Greater Manchester.

3.5.3 Groundwater monitoring wells were installed in each borehole, details of which are included on the borehole logs in Appendix 2. A sample of groundwater was collected from borehole BH101 for chemical analysis.

3.6 Plate Bearing Tests

3.6.1 Two plate bearing tests (PB1 and PB2) were carried out using a 300mm diameter plate with an 8 tonne JCB 3CX mechanical backhoe excavator as kentledge. The maximum load applied was 75 kN/m2, with one unloading cycle included to provide an indication of the elastic (reversible)

Caulmert Ltd 2010.7.VWM.DEO.PAC 4 April 2015 Viridor Waste Management Ltd Concrete Slab for Glass Handling, Storage and Transfer Factual Ground Investigation Report

and irreversible deformation that has occurred. The results of the plate bearing tests are presented in Appendix 5.

3.7 Dynamic Cone Penetrometer Testing

3.7.1 Four in situ dynamic cone penetrometer tests (DCP301 to DCP304) were carried out using handheld equipment. Two of the tests, DCP301 and DCP302, were carried out at the location of plate bearing tests PB1 and PB2 respectively. The testing results are presented in Appendix 6.

3.8 Other Information – Existing Foundations

3.8.1 Trial pit TP205 was excavated close to the existing vertical steel girders along the southwest perimeter of the site. It is apparent that the girders have been cast into a concrete base which is approximately 0.2 to 0.4 mBGL. It was not possible to check the girders along the northern perimeter due to the presence of buried services, but similar conditions should be anticipated.

4 GROUND CONDITIONS ENCOUNTERED

4.1 Sequence

4.1.1 The strata encountered during the investigation confirms the available geological information from the British Geological Survey (BGS). This shows bedrock geology comprising the Northampton Sand Formation (Ooidal Ironstone strata of the Jurassic Period), which are described as siliciclastic sediments comprising mud, silt, sand and gravel.

4.1.2 The BGS data indicates that no superficial strata are present beneath the site, which was confirmed by the exploratory holes. Made ground was encountered at all exploratory hole locations.

4.1.3 A relict topsoil was encountered in trial pits TP203 and TP204 at depths of 1.60 mBGL and 1.40 mBGL. A possible relict topsoil was encountered in borehole BH102 at 2.45 mBGL. These strata were found to directly overly the bedrock strata of the Northampton Sand Formation.

4.2 Made Ground

4.2.1 Made ground was observed at all exploratory hole locations at depths which ranged in thickness from 0.80m (trial pit TP206) to 2.75m (trial pit TP202). The composition of the made ground varied across the site, but typically comprised clay, sand or gravel, either as discrete layers or in variable mixtures of all three. Made ground was found to directly overly bedrock strata of the Northampton Sand Formation.

Clay

4.2.2 Clay strata were encountered in all exploratory hole locations, except trial pit TP206, at depths from 0.26 to 1.35 mBGL. In trial pit TP206 strata considered to be possible made ground comprising clay/silt and clay were encountered at depths of 0.80 mBGL and 1.65 mBGL respectively.

4.2.3 The clay was variable across the site with regard to strength and colour, ranging from soft brown clay in borehole BH101 (between 0.80 and 2.40 mBGL) to stiff to very stiff grey and light brown clay in trial pit TP203 (between 0.45 and 0.80 mBGL). The clay typically contained varying amounts of sand and gravel, which included concrete, brick, quartzite, coal, ironstone and slag, and occasional cobbles of brick, concrete and vitreous slag.

Sand and Gravel

4.2.4 Strata comprising sand, gravel, or a mixture of sand and gravel, were encountered at all exploratory hole locations at depths from ground level to 1.20 mBGL. The gravel observed

Caulmert Ltd 2010.7.VWM.DEO.PAC 6 April 2015 Viridor Waste Management Ltd Concrete Slab for Glass Handling, Storage and Transfer Factual Ground Investigation Report

within the made ground deposits included quartzite, sandstone, concrete, brick and slag.

4.2.5 In trial pit TP205 a layer of sand and gravel comprising compacted black vitreous slag was encountered at a depth of 0.80 to 1.35 mBGL.

4.2.6 A grey sandy angular to subangular gravel, possibly an MOT Type 1 aggregate sub-base material, was encountered in trial pit TP202 from ground level to 2.70mBGL. This directly overlies the natural strata of sand of the Northampton Sand Formation.

4.3 Bedrock Strata

Clay (Northampton sand Formation)

4.3.1 Clays considered to be of the Northampton Sand Formation was encountered at various depths in boreholes BH101 and BH102 and trial pits TP201, TP203, TP204 and TP205. These strata typically comprised soft to stiff reddish brown, light brown or grey sandy slightly gravelly clay.

4.3.2 These strata were encountered at depths ranging from 1.60 mBGL in trial pit TP203 to 3.70 mBGL in borehole BH101. Clay strata, considered to possibly comprise made ground, were also encountered in trial pit TP206 at a depth of 0.80 mBGL.

Sand and Gravel (Northampton Sand Formation)

4.3.3 A reddish brown, yellow and orangish brown and brownish yellow slightly clayey to very clayey or slightly gravelly to gravelly fine to coarse sand was encountered at all exploratory hole locations. The gravel typically comprised sandstone and ironstone.

4.3.4 These strata were encountered at depths ranging from 1.60 mBGL in trial pit TP204 to 5.50 mBGL in borehole BH102.

Silt (Whitby Mudstone Formation)

A dark grey silt, considered to be part of the Whitby Mudstone Formation, was encountered only in borehole BH101 at 7.00 mBGL. The base of this stratum was not proved at 7.20 mBGL.

4.4 Groundwater Conditions

4.4.1 Groundwater was encountered only in boreholes BH101 and BH102. The depth of each groundwater strike was recorded and the level monitored for a period of twenty minutes. Details of the groundwater strikes are presented in Table 4.1 below, and are also shown on the borehole logs in Appendix 2.

4.4.2 A groundwater and gas monitoring well was installed in each borehole, details of which are presented on the borehole logs in Appendix 2.

4.5 Ground Gas

4.5.1 Gas monitoring wells were installed in boreholes BH101 and BH102, for details refer to the borehole logs in Appendix 2. At the time of writing this report one monitoring visit had been completed on 13th April 2015, with a further 3 visits planned. The results of the monitoring will be provided as an addendum to this report.

4.5.2 At the time the visit was undertaken it was not possible to locate borehole BH101 which had been lost under some surface soils. The installation for BH102 had been impaired in the fact that the gas tap (a push-fit rubber bung) had been pushed into the standpipe and could not be removed to enable measurement of the groundwater level. Measurement of the ground gas was not impaired.

5 GEOTECHNICAL LABORATORY TESTING

5.1 Schedule of Laboratory Testing

5.1.1 The following tests were undertaken on selected samples recovered from the exploratory boreholes:

 Natural moisture content;  Atterberg limits (Plasticity Index);  Particle size distribution (PSD) analysis (including clay content);  Undrained triaxial shear strength (remoulded from bulk samples).

5.1.2 The laboratory testing results are presented in Appendix 7 of this report, and are summarised in Table 5.1 below:

5.2 Natural Moisture Content

5.2.1 A total of four samples were tested for their natural moisture content. All samples tested were collected in airtight sealed plastic containers to prevent moisture loss prior to testing. The samples tested were from depths of between 0.50 mBGL and 1.50 mBGL.

5.3 Plasticity Index (PI)

5.3.1 Plasticity Index (PI) testing was carried out on three samples recovered from the made ground in trial pits trial pits TP201, TP204 and TP205. The Casagrande plasticity chart plots are shown in Appendix 7, which indicates that the clays are of intermediate plasticity.

5.4 Particle Size Distribution (PSD) Analyses

5.4.1 A total of two PSD sieve and sedimentation analyses were completed on bulk samples recovered from the trial pits. One was from the sand and gravel deposits in trial pit TP202 at 1.50 mBGL, and one from the sand and gravel deposits in trial pit TP205 at 0.75 mBGL. The results are summarised in Table 5.2.

6 ENVIRONMENTAL RISK ASSESSMENT

6.1 Contaminated Land

6.1.1 Contaminated Land is defined in Part 2A of the Environmental Protection Act 1990 as “any land which appears to the local authority in whose area it is situated to be in such a condition, by reason of substances in, on or under the land, that:

a) “significant harm is being caused or there is a significant possibility of such harm being caused; or b) significant pollution of controlled waters is being caused, or there is a significant possibility of such pollution being caused.”

6.2 Risk Assessment

6.2.1 Land contamination and its risk to human health is a material consideration under the planning regime as it applies to the intended use of a site which requires that risk assessment for planning purposes should be consistent with the requirements under Part 2A. As a minimum, after carrying out the development and commencement of its use, the land should not be capable of being determined as Contaminated Land under Part 2A of the EPA 1990.

6.2.2 The definition of contaminated land is based on the principles of risk assessment. Risk is defined as a combination of:

 The probability, or frequency of exposure to a substance with the potential to cause harm, and;

 The seriousness of the consequence.

6.2.3 The basis of an environmental risk assessment involves identifying a ‘source’ of contamination, a ‘pathway’ along which the contamination may migrate and a ‘receptor’ at risk from the contamination.

 Source (contaminant): A substance that is in or under the land that has the potential to cause harm to the receptor.

 Pathway: The route(s) or means via which a receptor can be exposed to, or affected by, a contaminant.

 Receptor: The factor (person, built environment or ecosystems) that might adversely be affected by the source.

6.2.4 A pollutant linkage indicates that all three elements have been identified. The site can only be defined as ‘Contaminated Land’ if a pollutant linkage exists and the contamination meets the

Caulmert Ltd 2010.7.VWM.DEO.PAC 12 April 2015 Viridor Waste Management Ltd Concrete Slab for Glass Handling, Storage and Transfer Factual Ground Investigation Report

criteria in Section 6.2.3 above.

6.2.5 Current guidance proposes a four-stage approach for the assessment of contamination and the associated risks, and these are:

 Hazard identification;

 Hazard assessment;

 Risk assessment;

 Risk evaluation.

6.2.6 The hazard identification and hazard assessment have been based upon the phase 1 geo-environmental assessment and formed the conceptual site model, detailed in our report, reference 2010.2.VWM.DEO.PAC.A1 dated March 2015.

6.2.7 These risks were considered in terms of the detail of the intrusive works, sampling and testing. The results of the investigation works have been assessed in order to update the conceptual model and to determine whether the original preliminary risk assessment was valid. The reassessment is presented in the sections below.

6.2.8 The results of the chemical testing on soils have been compared with published Soil Guideline Values (SGV), Generic Assessment Criteria (GAC) and C4SL levels as an initial screen to determine if more detailed assessment is required.

6.2.9 The proposed development is for the construction of a concrete slab with bays on top used for the storage and handling of waste glass, which fits well with the CLEA commercial and industrial (C&I) end-use. Therefore, for the commercial end use screening values (SGVs, GACs and C4SLs) for a C&I scenario have been used. The concentrations of contaminants were all below their respective guideline values and are therefore not considered further for statistical analysis.

6.2.10 The laboratory testing reports and the data for the soil samples are presented with the full results presented in Appendix 8. All of the measured concentrations for the determinands tested were below the Tier 1 screening values for C&I land use, therefore the risk to the proposed development is considered to be LOW.

6.2.11 One groundwater sample was also tested and the majority of determinands were recorded as being below the limit of detection (LOD). Of those substances that did record a value above the LOD the concentrations were typically at or marginally above LOD, the details of which are presented in Table 6.1 below.

Asbestos

6.2.12 Laboratory screening to test for the presence of asbestos was undertaken on four samples of the made ground recovered from the trial pits. No asbestos fibres were detected in three of the trial pits (TP201, TP203 and TP304), however asbestos (amosite) fibres were detected in trial pit TP206 at 0.20 mBGL.

6.2.13 The presence of asbestos fibres in the soil presents a possible risk to human health via inhalation of the fibres. Therefore suitable health and safety and control measures should be implemented during construction works to prevent workers becoming exposed to the risk of inhalation of the fibres. As the site will be covered by concrete hardstanding the risk to future site users is considered to be negligible.

6.2.14 It is recommended that an asbestos management plan should be implemented to protect future site users from becoming exposed to potentially becoming exposed to asbestos. If buried services are installed at a later date then those undertaking the work should be made aware of the potential risk involved in excavating the made ground deposits so that suitable health and safety precautions can be implemented.

6.2.15 The Hazardous Waste (England and Wales) Regulations 2011 and the ‘Hazardous Waste – Interpretation of the definition and classification of hazardous waste (3rd Edition 2013)’ regulations states the following with regard to contamination of soils containing asbestos:

“The assessment of asbestos containing waste considers both the presence of asbestos as

• fibres that are free and dispersed, and

• identifiable pieces of asbestos containing material

Caulmert Ltd 2010.7.VWM.DEO.PAC 14 April 2015 Viridor Waste Management Ltd Concrete Slab for Glass Handling, Storage and Transfer Factual Ground Investigation Report

If the waste contains fibres that are free and dispersed then the waste will be hazardous if the waste as a whole contains 0.1% or more asbestos.

If the waste contains any identifiable pieces of suspected asbestos containing material they must be assessed as set out below. This would also apply to any dispersed fibres produced by deliberately breaking up such identifiable pieces.

Where the waste contains identifiable pieces of asbestos containing material (i.e. any particle of a size that can be identified as potentially being asbestos by a competent person if examined by the naked eye), then these pieces must be assessed separately. The waste is hazardous if the concentration of asbestos in the piece of asbestos containing material is 0.1% or more. The waste is regarded as a mixed waste (see example 1) and classified accordingly.”

6.2.16 Quantification of the asbestos fibres detected in the sample recovered from site has not been undertaken at the time of writing this report, and if soils are to be removed from site then it is recommended that further screening and quantification should be completed before construction works commence.

6.3 Updated Conceptual Site Model

6.3.1 The potential pollutant linkages for the proposed development identified by the phase 1 preliminary risk assessment have been updated based on the findings of the phase 2 investigation are presented in Table 6.2 below.

6.3.2 The risk assessment is based upon available information relating to the site. Should ground conditions prove inconsistent with those with those outlined in this report, or gross contamination is encountered during construction works, Caulmert should be contacted to enable further assessment.

Chemical Screening Criteria

Rationale

For the protection of human health screening criteria were selected from published data either from the Department for the Environment, Food and Rural Affairs (Defra) and Environment Agency (EA) (C4SLs) or equivalent generic assessment criteria (GACs) as published by LQM/CIEH and/or EIC. Generic values were selected based on a soil organic matter content of 1%, which was determined by laboratory testing. The possible generic end-use scenario considered in the assessment of risks to long term human health was commercial and industrial (C&I), based on the site being a commercial property. As the site will be covered in concrete hardstanding soils are only likely to come into contact with site development/maintenance workers who will be using appropriate working practices and protective equipment/clothing.

The C&I scenario is defined as a standard end use in the UK Contaminated Land Exposure Assessment (CLEA) model and so generic data are available.

If exceedances were recorded, the relevant data sets would be reassessed using the statistical methods as set out in “Guidance on Comparing Soil Contamination Data with a Critical Concentration”, CL:AIRE/CIEH, May 2008.

Controlled waters screening was undertaken by comparing soil leachate and groundwater chemical data against environmental quality standards (EQS) as published by the Environment Agency. In the absence of appropriate EQS values, UK or EU drinking water standards (DWS) were used. In the absence of DWS values other screening criteria from the World Health Organisation (WHO) or the United States Environmental Protection Agency (USEPA) were used.

It may become evident following further investigation and analysis that additional contaminants of concern (CoCs) come to light that are not present in the current list which may require screening criteria to be applied. If this becomes the case additional criteria shall be selected/derived and submitted to the regulators for comment and agreement.
