Samples collected from VF4 on 07/03/2016 recorded the highest concentration (9.74 mg/l) of boron in this borehole since monitoring commenced, with concentrations falling significantly to 3.77 mg/l for samples collected on 06/06/2016; Cadmium concentrations have remained within historical ranges at both monitoring locations, samples collected on 06/06/2016 from both VF4 and VF6 showed higher concentrations of 0.00144 and 0.00302 mg/l respectively however no discernible trends are observed when concentrations fell significantly in the third quarter of 2016; Vanadium recorded in VF6 is higher than that recorded in VF4 during this monitoring period. Concentrations of vanadium in VF4 are very stable and low, existing in a narrow range, whilst VF6 shows more variability; and All concentrations are largely comparable to those recorded during previous monitoring events at site. No leachate composition control and trigger levels are specified in the PPC Permit or in the Leachate Management Plan1 submitted to SEPA in November 2009. 2.2 ‘Leachate’ Levels A summary of ‘leachate’ elevations collected on a quarterly basis during the review period are presented as a time-series plot below in Figure 2-1. A summary of all ‘leachate’ elevation data, showing long term trends is presented in Appendix C. 1 SLR Consulting Limited, November 2009, Valleyfield Ash Lagoons Leachate Management Plan, Condition 6.4.1, SLR Ref 405-0481-00020-001.

It is noted that concentrations for samples collected on 06/09/2016 were significantly lower at 0.00229 and 0.00461 mg/l for ES1 and ES2 respectively, remaining low during the fourth 2016 quarterly sampling round; cadmium concentrations were generally low and very stable throughout 2016, however it is noted that samples collected on 06/06/2016 presented higher concentrations at 0.0108 and 0.00951 mg/l for ES1 and ES1 respectively with ES1 presenting its highest concentration since monitoring began. Concentrations for cadmium in samples collected on 06/09/2016 fell significantly to 0.00008 and 0.00048 mg/l for ES1 and ES2 respectively, remaining low during the fourth 2016 quarterly sampling round; molybdenum concentrations for samples collected at ES1 on 07/03/2016 were the highest since 2012 at 0.165 mg/l with samples collected at ES2 on 07/03/2016 were significantly lower at 0.0548 mg/l. Concentrations of molybdenum in samples collected on 06/06/2016 were very low at 0.0024 and 0.00501 mg/l for ES1 and ES2 respectively; selenium concentrations for samples collected on 06/06/2016 were the highest since 2010 at 0.191 and 1.178 mg/l for ES1 and ES2 respectively. Concentrations for selenium in samples collected 06/09/2016 fell significantly to 0.00081 and 0.00486 mg/l for ES1 and ES2 respectively; vanadium concentrations were generally very stable and low however samples collected for ES1 on 07/03/2016 were the highest since 2012 at 0.0873 mg/l. Samples collected from ES1 on 06/06/2016 presented vanadium concentration significantly lower at 0.0024 mg/l; in general there is little difference between upstream and downstream estuarine water during 2015; and samples collected during the third and fourth 2016 quarterly rounds presented very stable and low concentrations for each determinand and no specific trends are noted in the monitoring record.

It should be noted that the monitoring suite analysed is that stated in Table 13 of the Groundwater Management Plan and HRA Review2, which is a revision to that stated in the original PPC Permit. 5.1 Groundwater Quality Time-series plots of selected determinands for the review period are presented in Appendix G with raw data presented in Appendix A. Review of the monitoring data indicates the following:        Antimony concentrations are generally very low remaining significantly below both control and trigger levels in all boreholes for 2016 with the exception of samples collected from VF1 during the first quarterly monitoring event of 2016 where the trigger level (0.00625 mg/l) was exceeded with a concentration of 0.00782 mg/l. It is noted that concentrations for samples collected at VF1 fell below the LoD (<0.0016 mg/l) in the second and third monitoring events of 2016; Boron and molybdenum concentrations are generally very stable, existing in a narrow range (excluding VF8 and VF10) and within the historic ranges at all monitoring locations. VF8 and VF10 continue to present the highest concentrations of boron in monitored boreholes; Cadmium concentrations are within historic ranges at all monitoring locations during 2016 however several recorded elevated concentrations during the second quarterly monitoring round (only): VF3D, VF5, VF7, VF8, VF9 and VF10. Concentrations for all monitoring locations for the third and fourth 2016 quarterly monitoring events show a significant decrease and return the values typical of the long term monitoring record; Selenium concentrations presented within historic ranges for all monitoring locations. It is noted that the first and second quarterly monitoring events recorded concentrations within the typical ranges historically recorded by each monitoring well however in the third and fourth 2016 quarterly monitoring events concentrations fell significantly for all monitoring wells to below 0.00462 mg/l; Vanadium concentrations are very low and stable, existing within historic monitoring data ranges; Concentrations recorded in all groundwater monitoring boreholes have generally not shown any significant rising trends; and naphthalene has not been recorded above the LoD (<0.0001mg/l) throughout the review period. Further review of the priority determinands is presented in Appendix H and Section 5.2 of this report. 5.2 Groundwater Trigger Events For the purposes of this report groundwater quality data has been assessed against the control and trigger levels specified in Table 14 of the Groundwater Management Plan and HRA Review2, submitted to SEPA in November 2009 which have been determined in accordance with Permit Condition 10.3.2 and are considered more appropriate for assessing groundwater quality at site than those originally stated in the PPC Permit.

Table 5-1 below summarises trigger events that have occurred during the review period and the results of repeat sampling (see italics). It should be noted that a trigger event occurs only when both the control level and the trigger level have been exceeded.

No trigger events were recorded for antimony or vanadium throughout the review period. Following review of the control charts the following observations are made:   5.3 Boron concentrations at monitoring location VF8 exceeded control levels during September 2016, however repeat sampling presented significantly lower concentrations below both control and trigger levels. Concentrations remained below both control and trigger levels for samples collected in the fourth 2016 quarterly monitoring event; and Cadmium concentrations for monitoring locations VF3D (0.000561 mg/l), VF9 (0.00493 mg/l) and VF10 (0.0017 mg/l) all presented an exceedance both control and trigger levels in June 2016 however subsequent sampling in 2016 in September and November at all locations showed a significant fall in concentrations, and below the borehole specific trigger levels. Groundwater Elevations Groundwater elevations were obtained from the groundwater monitoring boreholes on a quarterly basis in accordance with the PPC Permit. All groundwater elevations are compared to tide prediction levels for Kincardine obtained from the Admiralty easytide website (http://easytide.ukho.gov.uk) to determine whether measurements have been collected at high or low tide or during flood or ebb. A time-series plot of groundwater elevations for the review period is presented below, with summary statistics presented in Table 5-2. A groundwater hydrograph of the entire monitoring record is presented in Appendix I.

VF1 has the greatest range suggesting that groundwater here is strongly influenced by the tide. The eastern boreholes VF5 and VF8 record the lowest ranges on site of less than 0.5 m. Groundwater elevations are greatest in boreholes VF3D, VF9, VF11 and VF12, located within the centre and north of the site, with the lowest elevations recorded in boreholes VF1, VF7, VF8 and VF10, which are located along the perimeter. This confirms that the groundwater flow direction is from the lagoons in a radial direction towards the east, south and west (i.e. towards the estuary), as stated in Section 3.2 of the Groundwater Management Plan and HRA Review report. SLR Scottish Power Generation Ltd Valleyfield Ash Lagoons: PPC/A/1004266 2016 Annual Environmental Review 14 405.00481.00033.001 March 2017 Borehole VF11 continues to record groundwater elevations above ground level confirming that this borehole monitors an artesian aquifer. Review of the long term groundwater elevations, presented in Appendix I, indicates that the range of groundwater elevations in most of the boreholes is generally less than two metres. VF1 recorded its highest groundwater elevation during monitoring on 06/06/2016 at 2.68 m AOD since monitoring commenced. In summary, with the exception of VF1 on 06/06/2016, groundwater elevations recorded in 2016 have remained within elevations recorded in the baseline and long term monitoring record. SLR Scottish Power Generation Ltd Valleyfield Ash Lagoons: PPC/A/1004266 2016 Annual Environmental Review 6.0 15 405.00481.00033.001 March 2017 GAS MONITORING DATA Perimeter landfill gas concentrations were monitored in all perimeter groundwater monitoring boreholes and the two PFA boreholes on a quarterly basis. Readings of methane, carbon dioxide, oxygen, atmospheric pressure and differential pressure were taken during each monitoring event. Time-series plots of methane and carbon dioxide concentrations recorded during the review period are presented in Appendix J, together with long term monitoring data. Summary statistics for oxygen, atmospheric pressure and differential pressure are presented in Table 6-1 with exceedences of trigger levels for methane and carbon dioxide presented in Table 62. It should be noted that the trigger levels which the results are compared with in Table 6-2 are the site specific trigger levels proposed in the Gas Management Plan3 rather than those stated in the PPC Permit, which are the default trigger levels for non-hazardous waste landfill sites. Control charts are also presented within Appendix J. Review of Table 6-2 highlights the following:    3 Methane:  VF12 presented three exceedances of its methane trigger level (7.9 % vol.) on 07/062016 (18.6 % vol.), 07/09/2016 (15.3 % vol.) and 30/11/2016 (12.1 % vol.). Repeat testing conducted recorded methane concentrations below the trigger lev with 3.6, 7.4 and 1.4 % vol respectively; and  Monitoring locations VF1, VF4, VF6, VF7, VF8, VF9, VF10 and VF11 recorded their highest concentrations of methane during this monitoring period, however concentrations remained significantly below trigger levels. Carbon dioxide:  VF5 recorded two incidents of carbon dioxide trigger level (1.5 % vol.) exceedance on 07/09/2016 and 30/11/2016 with concentrations of 2.5 and 2.3 % vol respectively. Repeat sampling conduced recorded carbon dioxide concentrations below the trigger level with concentrations of 1.2 % vol on both exceedance incidents;  VF7 recorded two incidents of carbon dioxide trigger level (1.5 % vol.) exceedance on 07/09/2016 and 30/11/2016 with concentrations of 2.4 and 2.2 % vol respectively. Repeat sampling conduced recorded carbon dioxide concentrations below the trigger level with concentrations of 1.4 and 0.9 % vol on 07/09/2016 and 30/11/2016 respectively;  VF12 recorded an exceedance of its carbon dioxide trigger level (2.1 % vol.) on 07/09/2016 with a concentration of 2.4 % vol. It is noted that repeat sampling conducted recorded a concentration of 1.3 % vol.; and  VF10 continues to record the highest concentrations of carbon dioxide in monitored boreholes however concentrations remain below its trigger level (7.4 % vol.). Due to heavy rain, standpipes of monitoring wells VF3D and VF11 on 08/03/2016 were both flooded and gas analysis was not possible.

No significant engineering works have been undertaken at the site during the reporting period and ash deposition occurred only during the first quarter of 2016. 7.2 Waste Characterisation In accordance with the PPC Permit, sampling of the waste has been undertaken for the period whilst the Valleyfield site continued to accept ash from Longannet Power Station and the monitoring quarter immediately after (March and June 2016). A single sample of the PFA waste was obtained as part of the quarterly monitoring suite in first and second quarters of 2016, which has undergone a 2-batch leachability testing, together with analysis of the solid waste. Results are presented in Appendix A. The results from 2016 suggest that the solid waste typically has an alkaline pH of between 9.16 and 9.77, while organic carbon content is recorded at 11.8 and 6.76 % (classed as hazardous wastel) for samples collected 07/03/2016 and 06/06/2016 respectively, which is largely comparable to previous results. It is noted that leached dissolved organic carbon was below the LoD for samples collected in 2016. The vast majority of parameters, and in particular substances such as PAHs and PCBs, fall below the laboratory method detection limit. Concentrations recorded during 2016 are similar to those recorded as part of the PPC Application and the previous Annual Monitoring Reviews. SLR Scottish Power Generation Ltd Valleyfield Ash Lagoons: PPC/A/1004266 2016 Annual Environmental Review 8.0 19 405.00481.00023.001 March 2017 ACTIONS AND RECOMMENDATIONS The condition of the boreholes remains satisfactory after the remediation works undertaken in November / December 2013. The gas and groundwater monitoring equipment also remains in satisfactory condition and conforms to the original monitoring borehole designs agreed during the PPC permitting works. Longannet Power Station has ceased the deposition of ash to the Valleyfield Ash Lagoons, however it is proposed that quarterly monitoring in accordance with the details set out in the PPC Permit and supporting Management Plans continues during the post-closure phase until a timescale for monitoring reduction or cessation is agreed with SEPA.

Results are expressed on a dry weight basis (dried at 35ºC) for all soil analyses except for the following: NRA and CEN Leach tests, flash point LOI, pH, ammonium as NH4 by the BRE method, VOC TICs and SVOC TICs. 20. For the BSEN 12457-3 two batch process to allow the cumulative release to be calculated, the volume of the leachate produced is measured and filtered for all tests. We therefore cannot carry out any unfiltered analysis. The tests affected include volatiles GCFID/GCMS and all subcontracted analysis. 2. Samples will be run in duplicate upon request, but an additional charge may be incurred. 3. If sufficient sample is received a sub sample will be retained free of charge for 30 days after analysis is completed (e-mailed) for all sample types unless the sample is destroyed on testing. The prepared soil sub sample that is analysed for asbestos will be retained for a period of 6 months after the analysis date. All bulk samples will be retained for a period of 6 months after the analysis date. All samples received and not scheduled will be disposed of one month after the date of receipt unless we are instructed to the contrary. Once the initial period has expired, a storage charge will be applied for each month or part thereof until the client cancels the request for sample storage. ALcontrol Laboratories reserve the right to charge for samples received and stored but not analysed. 4. With respect to turnaround, we will always endeavour to meet client requirements wherever possible, but turnaround times cannot be absolutely guaranteed due to so many variables beyond our control. 5. We take responsibility for any test performed by sub -contractors (marked with an asterisk). We endeavour to use UKAS/MCERTS Accredited Laboratories, who either complete a quality questionnaire or are audited by ourselves. For some determinands there are no UKAS/MCERTS Accredited Laboratories, in this instance a laboratory with a known track record will be utilised. 6. When requested, the individual sub sample scheduled will be analysed in house for the presence of asbestos fibres and asbestos containing material by our documented in house method TM048 based on HSG 248 (2005), which is accredited to ISO17025. If a specific asbestos fibre type is not found this will be reported as “Not detected”. If no asbestos fibre types are found all will be reported as “Not detected” and the sub sample analysed deemed to be clear of asbestos. If an asbestos fibre type is found it will be reported as detected (for each fibre type found). Testing can be carried out on asbestos positive samples, but, due to Health and Safety considerations, may be replaced by alternative tests or reported as No Determination Possible (NDP). The quantity of asbestos present is not determined unless specifically requested. 7. If no separate volatile sample is supplied by the client, or if a headspace or sediment is present in the volatile sample, the integrity of the data may be compromised. This will be flagged up as an invalid VOC on the test schedule and the result marked as deviating on the test certificate. 8. If appropriate preserved bottles are not received preservation will take place on receipt . However, the integrity of the data may be compromised. 9. NDP - No determination possible due to insufficient /unsuitable sample. 10. Metals in water are performed on a filtered sample, and therefore represent dissolved metals - total metals must be requested separately. 11. Results relate only to the items tested. 12. LoDs (Limit of Detection) for wet tests reported on a dry weight basis are not corrected for moisture content. 13. Surrogate recoveries - Surrogates are added to your sample to monitor recovery of the test requested. A % recovery is reported, results are not corrected for the recovery measured. Typical recoveries for organics tests are 70-130%, they are generally wider for volatiles analysis, 50-150%. Recoveries in soils are affected by organic rich or clay rich matrices. Waters can be affected by remediation fluids or high amounts of sediment . Test results are only ever reported if all of the associated quality checks pass; it is assumed that all recoveries outside of the values above are due to matrix affect . 21. For leachate preparations other than Zero Headspace Extraction (ZHE) volatile loss may occur. 22. We are accredited to MCERTS for sand, clay and loam /topsoil, or any of these materials - whether these are derived from naturally occurring soil profiles, or from fill /made ground, as long as these materials constitute the major part of the sample. Other coarse granular material such as concrete, gravel and brick are not accredited if they comprise the major part of the sample. 23. Analysis and identification of specific compounds using GCFID is by retention time only, and we routinely calibrate and quantify for benzene, toluene, ethylbenzenes and xylenes (BTEX). For total volatiles in the C5-C12 range, the total area of the chromatogram is integrated and expressed as ug /kg or ug/l. Although this analysis is commonly used for the quantification of gasoline range organics (GRO), the system will also detect other compounds such as chlorinated solvents, and this may lead to a falsely high result with respect to hydrocarbons only. It is not possible to specifically identify these non-hydrocarbons, as standards are not routinely run for any other compounds, and for more definitive identification, volatiles by GCMS should be utilised. 24. Tentatively Identified Compounds (TICs) are non-target peaks in VOC and SVOC analysis. All non-target peaks detected with a concentration above the LoD are subjected to a mass spectral library search. Non-target peaks with a library search confidence of >75% are reported based on the best mass spectral library match. When a non-target peak with a library search confidence of <75% is detected it is reported as “mixed hydrocarbons”. Non-target compounds identified from the scan data are semi-quantified relative to one of the deuterated internal standards, under the same chromatographic conditions as the target compounds.

Asbestos Identification of Asbestos in Bulk Materials & Soils The results for identification of asbestos in bulk materials are obtained from supplied bulk materials which have been examined to determine the presence of asbestos fibres using ALcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005). The results for identification of asbestos in soils are obtained from a homogenised sub sample which has been examined to determine the presence of asbestos fibres using ALcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005). Asbestos Type 14. Product analyses - Organic analyses on products can only be semi -quantitative due to the matrix effects and high dilution factors employed. 15. Phenols monohydric by HPLC include phenol, cresols (2-Methylphenol, 3-Methylphenol and 4-Methylphenol) and Xylenols (2,3 Dimethylphenol, 2,4 Dimethylphenol, 2,5 Dimethylphenol, 2,6 Dimethylphenol, 3,4 Dimethyphenol, 3,5 Dimethylphenol).

In certain circumstances the method detection limit may be elevated due to the sample being outside the calibration range. Other factors that may contribute to this include possible interferences. In both cases the sample would be diluted which would cause the method detection limit to be raised. 19. Mercury results quoted on soils will not include volatile mercury as the analysis is performed on a dried and crushed sample. Common Name Chrysotile - Visual Estimation Of Fibre Content Estimation of fibre content is not permitted as part of our UKAS accredited test other than : - Trace - Where only one or two asbestos fibres were identified. Further guidance on typical asbestos fibre content of manufactured products can be found in HSG 264. The identification of asbestos containing materials and soils falls within our schedule of tests for which we hold UKAS accreditation, however opinions, interpretations and all other information contained in the report are outside the scope of UKAS accreditation. 15:37:39 17/03/2016 Modification Date: Page 18 of 18 17/03/2016 Unit 7-8 Hawarden Business Park Manor Road (off Manor Lane) Hawarden Deeside CH5 3US Tel: (01244) 528700 Fax: (01244) 528701 email: mkt@alcontrol.com Website: www.alcontrol.com SLR Consulting Ltd Floor 2 4/5 Lochside View Edinburgh Park Edinburgh Lanarkshire EH12 9DH Attention: Zak Ritchie CERTIFICATE OF ANALYSIS Date: 24 June 2016 Customer: H_SLR_EDH Sample Delivery Group (SDG): 160608-88 Your Reference: Location: Report No: 405.00481.00033 Valleyfields 366319 We received 15 samples on Wednesday June 08, 2016 and 15 of these samples were scheduled for analysis which was completed on Friday June 24, 2016.

Results are expressed on a dry weight basis (dried at 35ºC) for all soil analyses except for the following: NRA and CEN Leach tests, flash point LOI, pH, ammonium as NH4 by the BRE method, VOC TICs and SVOC TICs. 20. For the BSEN 12457-3 two batch process to allow the cumulative release to be calculated, the volume of the leachate produced is measured and filtered for all tests. We therefore cannot carry out any unfiltered analysis. The tests affected include volatiles GCFID/GCMS and all subcontracted analysis. 2. Samples will be run in duplicate upon request, but an additional charge may be incurred. 3. If sufficient sample is received a sub sample will be retained free of charge for 30 days after analysis is completed (e-mailed) for all sample types unless the sample is destroyed on testing. The prepared soil sub sample that is analysed for asbestos will be retained for a period of 6 months after the analysis date. All bulk samples will be retained for a period of 6 months after the analysis date. All samples received and not scheduled will be disposed of one month after the date of receipt unless we are instructed to the contrary. Once the initial period has expired, a storage charge will be applied for each month or part thereof until the client cancels the request for sample storage. ALcontrol Laboratories reserve the right to charge for samples received and stored but not analysed. 4. With respect to turnaround, we will always endeavour to meet client requirements wherever possible, but turnaround times cannot be absolutely guaranteed due to so many variables beyond our control. 5. We take responsibility for any test performed by sub -contractors (marked with an asterisk). We endeavour to use UKAS/MCERTS Accredited Laboratories, who either complete a quality questionnaire or are audited by ourselves. For some determinands there are no UKAS/MCERTS Accredited Laboratories, in this instance a laboratory with a known track record will be utilised. 6. When requested, the individual sub sample scheduled will be analysed in house for the presence of asbestos fibres and asbestos containing material by our documented in house method TM048 based on HSG 248 (2005), which is accredited to ISO17025. If a specific asbestos fibre type is not found this will be reported as “Not detected”. If no asbestos fibre types are found all will be reported as “Not detected” and the sub sample analysed deemed to be clear of asbestos. If an asbestos fibre type is found it will be reported as detected (for each fibre type found). Testing can be carried out on asbestos positive samples, but, due to Health and Safety considerations, may be replaced by alternative tests or reported as No Determination Possible (NDP). The quantity of asbestos present is not determined unless specifically requested. 7. If no separate volatile sample is supplied by the client, or if a headspace or sediment is present in the volatile sample, the integrity of the data may be compromised. This will be flagged up as an invalid VOC on the test schedule and the result marked as deviating on the test certificate. 8. If appropriate preserved bottles are not received preservation will take place on receipt . However, the integrity of the data may be compromised. 9. NDP - No determination possible due to insufficient /unsuitable sample. 10. Metals in water are performed on a filtered sample, and therefore represent dissolved metals - total metals must be requested separately. 11. Results relate only to the items tested. 12. LoDs (Limit of Detection) for wet tests reported on a dry weight basis are not corrected for moisture content. 13. Surrogate recoveries - Surrogates are added to your sample to monitor recovery of the test requested. A % recovery is reported, results are not corrected for the recovery measured. Typical recoveries for organics tests are 70-130%, they are generally wider for volatiles analysis, 50-150%. Recoveries in soils are affected by organic rich or clay rich matrices. Waters can be affected by remediation fluids or high amounts of sediment . Test results are only ever reported if all of the associated quality checks pass; it is assumed that all recoveries outside of the values above are due to matrix affect . 21. For leachate preparations other than Zero Headspace Extraction (ZHE) volatile loss may occur. 22. We are accredited to MCERTS for sand, clay and loam /topsoil, or any of these materials - whether these are derived from naturally occurring soil profiles, or from fill /made ground, as long as these materials constitute the major part of the sample. Other coarse granular material such as concrete, gravel and brick are not accredited if they comprise the major part of the sample. 23. Analysis and identification of specific compounds using GCFID is by retention time only, and we routinely calibrate and quantify for benzene, toluene, ethylbenzenes and xylenes (BTEX). For total volatiles in the C5-C12 range, the total area of the chromatogram is integrated and expressed as ug /kg or ug/l. Although this analysis is commonly used for the quantification of gasoline range organics (GRO), the system will also detect other compounds such as chlorinated solvents, and this may lead to a falsely high result with respect to hydrocarbons only. It is not possible to specifically identify these non-hydrocarbons, as standards are not routinely run for any other compounds, and for more definitive identification, volatiles by GCMS should be utilised. 24. Tentatively Identified Compounds (TICs) are non-target peaks in VOC and SVOC analysis. All non-target peaks detected with a concentration above the LoD are subjected to a mass spectral library search. Non-target peaks with a library search confidence of >75% are reported based on the best mass spectral library match. When a non-target peak with a library search confidence of <75% is detected it is reported as “mixed hydrocarbons”. Non-target compounds identified from the scan data are semi-quantified relative to one of the deuterated internal standards, under the same chromatographic conditions as the target compounds. This result is reported as a semi-quantitative value and reported as Tentatively Identified Compounds (TICs). TICs are outside the scope of UKAS accreditation and are not moisture corrected.

Asbestos Identification of Asbestos in Bulk Materials & Soils The results for identification of asbestos in bulk materials are obtained from supplied bulk materials which have been examined to determine the presence of asbestos fibres using ALcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005). The results for identification of asbestos in soils are obtained from a homogenised sub sample which has been examined to determine the presence of asbestos fibres using ALcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005). Asbestos Type 14. Product analyses - Organic analyses on products can only be semi -quantitative due to the matrix effects and high dilution factors employed. 15.

In certain circumstances the method detection limit may be elevated due to the sample being outside the calibration range. Other factors that may contribute to this include possible interferences.

Results are expressed on a dry weight basis (dried at 35ºC) for all soil analyses except for the following: NRA and CEN Leach tests, flash point LOI, pH, ammonium as NH4 by the BRE method, VOC TICs and SVOC TICs. 20. For the BSEN 12457-3 two batch process to allow the cumulative release to be calculated, the volume of the leachate produced is measured and filtered for all tests. We therefore cannot carry out any unfiltered analysis. The tests affected include volatiles GCFID/GCMS and all subcontracted analysis. 2. Samples will be run in duplicate upon request, but an additional charge may be incurred. 3. If sufficient sample is received a sub sample will be retained free of charge for 30 days after analysis is completed (e-mailed) for all sample types unless the sample is destroyed on testing. The prepared soil sub sample that is analysed for asbestos will be retained for a period of 6 months after the analysis date. All bulk samples will be retained for a period of 6 months after the analysis date. All samples received and not scheduled will be disposed of one month after the date of receipt unless we are instructed to the contrary. Once the initial period has expired, a storage charge will be applied for each month or part thereof until the client cancels the request for sample storage. ALcontrol Laboratories reserve the right to charge for samples received and stored but not analysed. 4. With respect to turnaround, we will always endeavour to meet client requirements wherever possible, but turnaround times cannot be absolutely guaranteed due to so many variables beyond our control. 5. We take responsibility for any test performed by sub -contractors (marked with an asterisk). We endeavour to use UKAS/MCERTS Accredited Laboratories, who either complete a quality questionnaire or are audited by ourselves. For some determinands there are no UKAS/MCERTS Accredited Laboratories, in this instance a laboratory with a known track record will be utilised. 6. When requested, the individual sub sample scheduled will be analysed in house for the presence of asbestos fibres and asbestos containing material by our documented in house method TM048 based on HSG 248 (2005), which is accredited to ISO17025. If a specific asbestos fibre type is not found this will be reported as “Not detected”. If no asbestos fibre types are found all will be reported as “Not detected” and the sub sample analysed deemed to be clear of asbestos. If an asbestos fibre type is found it will be reported as detected (for each fibre type found). Testing can be carried out on asbestos positive samples, but, due to Health and Safety considerations, may be replaced by alternative tests or reported as No Determination Possible (NDP). The quantity of asbestos present is not determined unless specifically requested. 7. If no separate volatile sample is supplied by the client, or if a headspace or sediment is present in the volatile sample, the integrity of the data may be compromised. This will be flagged up as an invalid VOC on the test schedule and the result marked as deviating on the test certificate. 8. If appropriate preserved bottles are not received preservation will take place on receipt . However, the integrity of the data may be compromised. 9. NDP - No determination possible due to insufficient /unsuitable sample. 10. Metals in water are performed on a filtered sample, and therefore represent dissolved metals - total metals must be requested separately. 11. Results relate only to the items tested. 12. LoDs (Limit of Detection) for wet tests reported on a dry weight basis are not corrected for moisture content. 13. Surrogate recoveries - Surrogates are added to your sample to monitor recovery of the test requested. A % recovery is reported, results are not corrected for the recovery measured. Typical recoveries for organics tests are 70-130%, they are generally wider for volatiles analysis, 50-150%. Recoveries in soils are affected by organic rich or clay rich matrices. Waters can be affected by remediation fluids or high amounts of sediment . Test results are only ever reported if all of the associated quality checks pass; it is assumed that all recoveries outside of the values above are due to matrix affect . 21. For leachate preparations other than Zero Headspace Extraction (ZHE) volatile loss may occur. 22. We are accredited to MCERTS for sand, clay and loam /topsoil, or any of these materials - whether these are derived from naturally occurring soil profiles, or from fill /made ground, as long as these materials constitute the major part of the sample. Other coarse granular material such as concrete, gravel and brick are not accredited if they comprise the major part of the sample. 23. Analysis and identification of specific compounds using GCFID is by retention time only, and we routinely calibrate and quantify for benzene, toluene, ethylbenzenes and xylenes (BTEX). For total volatiles in the C5-C12 range, the total area of the chromatogram is integrated and expressed as ug /kg or ug/l. Although this analysis is commonly used for the quantification of gasoline range organics (GRO), the system will also detect other compounds such as chlorinated solvents, and this may lead to a falsely high result with respect to hydrocarbons only. It is not possible to specifically identify these non-hydrocarbons, as standards are not routinely run for any other compounds, and for more definitive identification, volatiles by GCMS should be utilised. 24. Tentatively Identified Compounds (TICs) are non-target peaks in VOC and SVOC analysis. All non-target peaks detected with a concentration above the LoD are subjected to a mass spectral library search. Non-target peaks with a library search confidence of >75% are reported based on the best mass spectral library match. When a non-target peak with a library search confidence of <75% is detected it is reported as “mixed hydrocarbons”. Non-target compounds identified from the scan data are semi-quantified relative to one of the deuterated internal standards, under the same chromatographic conditions as the target compounds. This result is reported as a semi-quantitative value and reported as Tentatively Identified Compounds (TICs). TICs are outside the scope of UKAS accreditation and are not moisture corrected.

Results are expressed on a dry weight basis (dried at 35ºC) for all soil analyses except for the following: NRA and CEN Leach tests, flash point LOI, pH, ammonium as NH4 by the BRE method, VOC TICs and SVOC TICs. 20. For the BSEN 12457-3 two batch process to allow the cumulative release to be calculated, the volume of the leachate produced is measured and filtered for all tests. We therefore cannot carry out any unfiltered analysis. The tests affected include volatiles GCFID/GCMS and all subcontracted analysis. 2. Samples will be run in duplicate upon request, but an additional charge may be incurred. 3. If sufficient sample is received a sub sample will be retained free of charge for 30 days after analysis is completed (e-mailed) for all sample types unless the sample is destroyed on testing. The prepared soil sub sample that is analysed for asbestos will be retained for a period of 6 months after the analysis date. All bulk samples will be retained for a period of 6 months after the analysis date. All samples received and not scheduled will be disposed of one month after the date of receipt unless we are instructed to the contrary. Once the initial period has expired, a storage charge will be applied for each month or part thereof until the client cancels the request for sample storage. ALS reserve the right to charge for samples received and stored but not analysed. 4. With respect to turnaround, we will always endeavour to meet client requirements wherever possible, but turnaround times cannot be absolutely guaranteed due to so many variables beyond our control. 5. We take responsibility for any test performed by sub -contractors (marked with an asterisk). We endeavour to use UKAS/MCERTS Accredited Laboratories, who either complete a quality questionnaire or are audited by ourselves. For some determinands there are no UKAS/MCERTS Accredited Laboratories, in this instance a laboratory with a known track record will be utilised. 6. When requested, the individual sub sample scheduled will be analysed in house for the presence of asbestos fibres and asbestos containing material by our documented in house method TM048 based on HSG 248 (2005), which is accredited to ISO17025. If a specific asbestos fibre type is not found this will be reported as “Not detected”. If no asbestos fibre types are found all will be reported as “Not detected” and the sub sample analysed deemed to be clear of asbestos. If an asbestos fibre type is found it will be reported as detected (for each fibre type found). Testing can be carried out on asbestos positive samples, but, due to Health and Safety considerations, may be replaced by alternative tests or reported as No Determination Possible (NDP). The quantity of asbestos present is not determined unless specifically requested. 7. If no separate volatile sample is supplied by the client, or if a headspace or sediment is present in the volatile sample, the integrity of the data may be compromised. This will be flagged up as an invalid VOC on the test schedule and the result marked as deviating on the test certificate. 8. If appropriate preserved bottles are not received preservation will take place on receipt . However, the integrity of the data may be compromised. 9. NDP - No determination possible due to insufficient /unsuitable sample. 10. Metals in water are performed on a filtered sample, and therefore represent dissolved metals - total metals must be requested separately. 21. For leachate preparations other than Zero Headspace Extraction (ZHE) volatile loss may occur. 22. We are accredited to MCERTS for sand, clay and loam /topsoil, or any of these materials - whether these are derived from naturally occurring soil profiles, or from fill /made ground, as long as these materials constitute the major part of the sample. Other coarse granular material such as concrete, gravel and brick are not accredited if they comprise the major part of the sample. 23. Analysis and identification of specific compounds using GCFID is by retention time only, and we routinely calibrate and quantify for benzene, toluene, ethylbenzenes and xylenes (BTEX). For total volatiles in the C5-C12 range, the total area of the chromatogram is integrated and expressed as ug /kg or ug/l. Although this analysis is commonly used for the quantification of gasoline range organics (GRO), the system will also detect other compounds such as chlorinated solvents, and this may lead to a falsely high result with respect to hydrocarbons only. It is not possible to specifically identify these non-hydrocarbons, as standards are not routinely run for any other compounds, and for more definitive identification, volatiles by GCMS should be utilised. 24. Tentatively Identified Compounds (TICs) are non-target peaks in VOC and SVOC analysis. All non-target peaks detected with a concentration above the LoD are subjected to a mass spectral library search. Non-target peaks with a library search confidence of >75% are reported based on the best mass spectral library match. When a non-target peak with a library search confidence of <75% is detected it is reported as “mixed hydrocarbons”. Non-target compounds identified from the scan data are semi-quantified relative to one of the deuterated internal standards, under the same chromatographic conditions as the target compounds.

Surrogate recoveries - Surrogates are added to your sample to monitor recovery of the test requested. A % recovery is reported, results are not corrected for the recovery measured. Typical recoveries for organics tests are 70-130%, they are generally wider for volatiles analysis, 50-150%. Recoveries in soils are affected by organic rich or clay rich matrices. Waters can be affected by remediation fluids or high amounts of sediment . Test results are only ever reported if all of the associated quality checks pass; it is assumed that all recoveries outside of the values above are due to matrix affect . Identification of Asbestos in Bulk Materials & Soils The results for identification of asbestos in bulk materials are obtained from supplied bulk materials which have been examined to determine the presence of asbestos fibres using ALS (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005). The results for identification of asbestos in soils are obtained from a homogenised sub sample which has been examined to determine the presence of asbestos fibres using ALS (Hawarden) in-house method of transmitted/polarised light microscopy and central stop dispersion staining, based on HSG 248 (2005). 14. Product analyses - Organic analyses on products can only be semi -quantitative due to the matrix effects and high dilution factors employed. Asbe stos Type 15. Phenols monohydric by HPLC include phenol, cresols (2-Methylphenol, 3-Methylphenol and 4-Methylphenol) and Xylenols (2,3 Dimethylphenol, 2,4 Dimethylphenol, 2,5 Dimethylphenol, 2,6 Dimethylphenol, 3,4 Dimethyphenol, 3,5 Dimethylphenol). 16.

In certain circumstances the method detection limit may be elevated due to the sample being outside the calibration range. Other factors that may contribute to this include possible interferences. In both cases the sample would be diluted which would cause the method detection limit to be raised. 19. Mercury results quoted on soils will not include volatile mercury as the analysis is performed on a dried and crushed sample. Common Name Chrysoti le - Visual Estimation Of Fibre Content Estimation of fibre content is not permitted as part of our UKAS accredited test other than : - Trace - Where only one or two asbestos fibres were identified. Further guidance on typical asbestos fibre content of manufactured products can be found in HSG 264. The identification of asbestos containing materials and soils falls within our schedule of tests for which we hold UKAS accreditation, however opinions, interpretations and all other information contained in the report are outside the scope of UKAS accreditation. 15:56:52 13/12/2016 Modification Date: Page 13 of 13 13/12/2016 Appendix Selected Leachate Quality Chemographs SLR Scottish Power Generation Ltd.
