5 Ground Investigation Factual Report at Ellesmere Port - Baseline Project No : PN Monitoring Boreholes August INTRODUCTION A geo-environmental investigation was undertaken by Geotechnics Ltd at the site of a proposed exploratory gas production well in Ellesmere Port. The investigation was carried out to the instructions of the Engineer, URS Infrastructure & Environment UK Ltd on behalf of the Client, IGas Energy plc. This report describes the work undertaken and presents the data obtained. 2.0 OBJECT AND SCOPE OF THE INVESTIGATION The object of the investigation was to obtain information on the ground and groundwater conditions relating to the design of the proposed works within the limitations posed by trial hole numbers, locations, depths, methods adopted and the scope of approved in situ and laboratory testing. The investigation comprised cable percussive boreholes, in situ and laboratory testing and reporting. A Factual Report only was also commissioned. 3.0 PRESENTATION A description of the site and a summary of the procedures followed during the investigation process are presented in Sections 4 to 6. The factual data so obtained are presented in Appendices 2 to 5 of this report. Attention is drawn to the General Notes and Investigation Procedures presented in Appendix 6 to aid an understanding of the procedures followed and the context in which the report should be read. In addition, data in electronic format in accordance with The Electronic Transfer of Geotechnical Data from Ground Investigations (Third Edition) published by the AGS (the AGS Format) are presented separately on disk, together with a copy of the report in electronic PDF format. 4.0 THE SITE 4.1 Location The site is located approximately 0.35km north from Junction 8 of the M53 motorway and approximately 1.70km northeast of Overpool Railway Station. The approximate Ordnance Survey Grid Reference for the site is SJ and an extract from the relevant 1:50,000 Scale O.S. Map is included as Appendix Description The site comprises a portion of cleared land situated between industrial units. The site is irregular in shape with maximum dimensions of approximately 175m (northwest to southeast) by 85m (southwest to northeast). The site surface comprises hardcore with rough vegetation around the perimeter and is generally level. Access to the site is off Merseyton Road. 4.3 Site Geology The 1:50,000 scale BGS geological map Sheet 97 (Runcorn) Drift Edition dated 1977 shows the site to be underlain by Glacial Till (recorded as Boulder Clay ). As the site has previously been developed, a thickness of Made Ground should be anticipated. Borehole logs from a previous ground investigation in 2011 at the site reported Made Ground. The Made Ground consisted of reworked Glacial Till, ash, brick and concrete. The Solid geology Sheet 97 dated 1980 shows the site to be underlain by the Chester Pebble Beds Formation, part of the Sherwood Sandstone Group of Triassic age. This is typically fine to coarse grained Sandstone and commonly pebbly.

6 5.0 PROCEDURE 5.1 Commissioning The work was awarded following submission of a tender for work designed by the Engineer for ground investigation of the site in accordance with the Client s requirements. 5.2 General The procedures followed in this site investigation are based on BS 5930: A2:2010 Code of Practice for Site Investigations and BS (2011) Investigation of Potentially Contaminated Sites. The positions of the investigation points are shown on the Exploratory Hole Location Plan in Appendix 5. The Exploratory Hole locations were specified by the Engineer. Co-ordinates and levels shown on the Exploratory Hole Records were obtained using a Leica GPS survey device. The depths quoted on the records are in metres below ground level. Prior to the commencement of any intrusive investigative works, available buried services information was consulted. At each exploratory hole location an inspection pit was excavated using hand tools to a depth of 1.20m below ground level to check for the presence of underground services. Prior to and on completion of the excavation, the location was scanned using a cable avoidance tool (CAT). 5.3 Cable Percussion Boreholes Six (6 No.), cable percussion boreholes (numbered BH101 to BH103, BH104A and BH105 to BH106) were sunk using 250mm and 200mm diameter casing and tools to depths varying between 3.19m and 28.60m below ground level. The work was carried out between 8 th and 30 th July Cable Percussion Borehole BH104 was terminated within its inspection pit on encountering possible asbestos. The ground within the pit was dampened down prior to backfilling. Samples were taken from the service inspection pit, where appropriate, for laboratory examination and analysis. Representative disturbed (D) samples of the soils encountered were obtained at regular intervals. In addition, environmental soil samples (ES) were recovered at the depths indicated on the Borehole Records. On encountering groundwater, boring operations were suspended for 20 minutes in order to record any rise in water level. Full details of groundwater observations during site work are included on the Borehole Records. Photo-ionisation detection (PID) tests were undertaken during the drilling by testing the headspace of the environmental soil samples taken. The tests were carried out using a suitably calibrated MiniRAE 2000 PID Meter fitted with a 10.6eV UV lamp. The results of the PID tests are presented on the Cable Percussion Borehole Records in Appendix 2, with the readings reported as Volatile Organic Compounds (VOCs) recorded in parts per million. On completion, standpipes were installed in Boreholes BH101 to BH103, BH104A and BH105 to BH106 (see Section 5.4). Cable Percussion Borehole BH104 was backfilled with arisings on completion. 5.4 Instrumentation and Monitoring Long-term monitoring of the gas and groundwater levels was made possible by the installation of standpipes as follows: Exploratory Hole 127mm Standpipe Slotted Pipe (m) Filter Zone (m) BH to to 3.19 BH to to BH to to BH104A to to BH to to BH to to Monitoring of the gas and groundwater levels will be undertaken by the Engineer. Development of the installations by airlifting to remove any sediment within the installations was undertaken between 29 th and 5 th August The airlifting techniques were carried out in accordance with BS ISO Annex D. Development of the boreholes continued until the water ran clean and as instructed by the Engineer. Following the well development, 50mm diameter pipes were installed within the 127mm standpipes to act as access dip tubes. The 50mm pipes were installed to the base of the 127mm standpipes.

7 In addition a bladder pump was installed in each borehole within the 127mm standpipe. The installations depths of the bladder pumps were specified by the Engineer and were as follows: Signed for and on behalf of Geotechnics Limited. Prepared by: Exploratory m bgl BH BH BH BH BH BH Headworks were installed to allow gas readings and which incorporate the airlines for the bladder pumps. 5.5 In situ Permeability Tests Following completion of the fieldwork in situ Falling Head Permeability tests were undertaken in the standpipes installed in Boreholes BH101 to BH103, BH104A, BH105 and BH106 in accordance with BS EN ISO :2012 and as instructed by the Engineer. Sarah Burt BSc (Hons), FGS Engineer Reviewed by: Colin Dodd BSc (Hons), MSc, CEng, MICE Principal Engineer The permeability has been estimated using the initial groundwater level measured in the standpipes and the results are presented in Appendix 3. No permeability has been estimated in boreholes BH101 and BH105 as the standpipes part or all of the test section is above the groundwater level such that the test section is not fully saturated. 6.0 LABORATORY TESTING 6.1 Geotechnical No geotechnical laboratory testing was commissioned by the Engineer/Client. 6.2 Contamination Selected samples of soil samples were tested at the laboratories of Jones Environmental Laboratory Ltd. (UKAS Accredited Laboratory, Number 4225) for a number of determinands in order to check on potential site contamination. The determinands were specified by the Engineer. The specified determinants are detailed on the results sheets in Appendix 4 together with the test result as well as the test method, accreditation and detection limit.

Samples are retained for not less than 6 months from the date of analysis unless specifically requested. Opinions lie outside the scope of our UKAS accreditation. Where the sample is not taken by a Jones Environmental Laboratory consultant, Jones Environmental Laboratory cannot be responsible for inaccurate or unrepresentative sampling.

45 NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS JE Job No.: SOILS 14/7843 Please note we are only MCERTS accredited for sand, loam and clay and any other matrix is outside our scope of accreditation. Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS accredited. It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be included unless we are requested to remove them. All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary. If we are instructed to keep samples, a storage charge of 1 (1.5 Euros) per sample per month will be applied until we are asked to dispose of them. If you have not already done so, please send us a purchase order if this is required by your company. Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately. All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35 C ±5 C unless otherwise stated. Moisture content for CEN Leachate tests are dried at 105 C ±5 C. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used. % Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings listed in order of ease of fibre release. WATERS Please note we are not a Drinking Water Inspectorate (DWI) Approved Laboratory. It is important that detection limits are carefully considered when requesting water analysis. UKAS accreditation applies to surface water and groundwater and one other matrix which is analysis specific, any other liquids are outside our scope of accreditation As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. DEVIATING SAMPLES Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and any test results that may be compromised highlighted on your deviating samples report. SURROGATES Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat, clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable limits for most organic methods are % and for VOCs are %. When surrogate recoveries are outside the performance criteria but the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected. DILUTIONS A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required. NOTE Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered indicative only, but this does not mean the data is not valid. Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

54 Jones Environmental Laboratory Asbestos Analysis Client Name: Reference: Location: Contact: Geotechnics PN Ellesmere Port Baseline Monitoring Sarah Burt Note: Analysis was carried out in accordance with our documented in-house methods PM042 and TM065 and HSG 248 by Stereo and Polarised Light Microscopy using Dispersion Staining Techniques and is covered by our UKAS accreditation. Samples are retained for not less than 6 months from the date of analysis unless specifically requested. Opinions lie outside the scope of our UKAS accreditation. Where the sample is not taken by a Jones Environmental Laboratory consultant, Jones Environmental Laboratory cannot be responsible for inaccurate or unrepresentative sampling. If asbestos fibres are reported at trace levels there will not be enough fibres to quantify and will be less than 0.001%.

56 NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS JE Job No.: SOILS 14/7843 Please note we are only MCERTS accredited for sand, loam and clay and any other matrix is outside our scope of accreditation. Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS accredited. It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be included unless we are requested to remove them. All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary. If we are instructed to keep samples, a storage charge of 1 (1.5 Euros) per sample per month will be applied until we are asked to dispose of them. If you have not already done so, please send us a purchase order if this is required by your company. Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately. All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35 C ±5 C unless otherwise stated. Moisture content for CEN Leachate tests are dried at 105 C ±5 C. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used. % Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings listed in order of ease of fibre release. WATERS Please note we are not a Drinking Water Inspectorate (DWI) Approved Laboratory. It is important that detection limits are carefully considered when requesting water analysis. UKAS accreditation applies to surface water and groundwater and one other matrix which is analysis specific, any other liquids are outside our scope of accreditation As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. DEVIATING SAMPLES Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and any test results that may be compromised highlighted on your deviating samples report. SURROGATES Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat, clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable limits for most organic methods are % and for VOCs are %. When surrogate recoveries are outside the performance criteria but the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected. DILUTIONS A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required. NOTE Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered indicative only, but this does not mean the data is not valid. Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

64 Jones Environmental Laboratory Asbestos Analysis Client Name: Reference: Location: Contact: Geotechnics PN Ellesmere Port Baseline Monitoring Sarah Burt Note: Analysis was carried out in accordance with our documented in-house methods PM042 and TM065 and HSG 248 by Stereo and Polarised Light Microscopy using Dispersion Staining Techniques and is covered by our UKAS accreditation. Samples are retained for not less than 6 months from the date of analysis unless specifically requested. Opinions lie outside the scope of our UKAS accreditation. Where the sample is not taken by a Jones Environmental Laboratory consultant, Jones Environmental Laboratory cannot be responsible for inaccurate or unrepresentative sampling. If asbestos fibres are reported at trace levels there will not be enough fibres to quantify and will be less than 0.001%.

66 NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS JE Job No.: SOILS 14/7843 Please note we are only MCERTS accredited for sand, loam and clay and any other matrix is outside our scope of accreditation. Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS accredited. It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be included unless we are requested to remove them. All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary. If we are instructed to keep samples, a storage charge of 1 (1.5 Euros) per sample per month will be applied until we are asked to dispose of them. If you have not already done so, please send us a purchase order if this is required by your company. Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately. All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35 C ±5 C unless otherwise stated. Moisture content for CEN Leachate tests are dried at 105 C ±5 C. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used. % Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings listed in order of ease of fibre release. WATERS Please note we are not a Drinking Water Inspectorate (DWI) Approved Laboratory. It is important that detection limits are carefully considered when requesting water analysis. UKAS accreditation applies to surface water and groundwater and one other matrix which is analysis specific, any other liquids are outside our scope of accreditation As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. DEVIATING SAMPLES Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and any test results that may be compromised highlighted on your deviating samples report. SURROGATES Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat, clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable limits for most organic methods are % and for VOCs are %. When surrogate recoveries are outside the performance criteria but the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected. DILUTIONS A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required. NOTE Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered indicative only, but this does not mean the data is not valid. Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

75 Jones Environmental Laboratory Asbestos Analysis Client Name: Reference: Location: Contact: Geotechnics PN Ellesmere Port Baseline Monitoring Sarah Burt Note: Analysis was carried out in accordance with our documented in-house methods PM042 and TM065 and HSG 248 by Stereo and Polarised Light Microscopy using Dispersion Staining Techniques and is covered by our UKAS accreditation. Samples are retained for not less than 6 months from the date of analysis unless specifically requested. Opinions lie outside the scope of our UKAS accreditation. Where the sample is not taken by a Jones Environmental Laboratory consultant, Jones Environmental Laboratory cannot be responsible for inaccurate or unrepresentative sampling. If asbestos fibres are reported at trace levels there will not be enough fibres to quantify and will be less than 0.001%.

77 NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS JE Job No.: SOILS 14/7843 Please note we are only MCERTS accredited for sand, loam and clay and any other matrix is outside our scope of accreditation. Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS accredited. It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be included unless we are requested to remove them. All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary. If we are instructed to keep samples, a storage charge of 1 (1.5 Euros) per sample per month will be applied until we are asked to dispose of them. If you have not already done so, please send us a purchase order if this is required by your company. Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately. All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35 C ±5 C unless otherwise stated. Moisture content for CEN Leachate tests are dried at 105 C ±5 C. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used. % Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings listed in order of ease of fibre release. WATERS Please note we are not a Drinking Water Inspectorate (DWI) Approved Laboratory. It is important that detection limits are carefully considered when requesting water analysis. UKAS accreditation applies to surface water and groundwater and one other matrix which is analysis specific, any other liquids are outside our scope of accreditation As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples. Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40. DEVIATING SAMPLES Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and any test results that may be compromised highlighted on your deviating samples report. SURROGATES Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat, clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable limits for most organic methods are % and for VOCs are %. When surrogate recoveries are outside the performance criteria but the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected. DILUTIONS A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required. NOTE Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered indicative only, but this does not mean the data is not valid. Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact the laboratory if further details are required of the circumstances which have led to the removal of accreditation.
