CONTAMINATION INFORMATIVE 1 The applicant is reminded that condition 22 (Contamination - Site investigation and quantitative risk assessment) remains to be discharged until a sufficient site investigation and quantitative risk assessment report is submitted in accordance with the requirements of the condition that includes works set out in the letter from Fairhurst for 66-74 Notting Hill Gate - Scheme of Investigation (Ref: CB/HB/117485/NHG/SchemeofInvestigation/RevA), dated 22 November 2018 andapproved by this authority. The applicant needs to ensure the consultants are aware of issues identified in the submissions for condition 21 and these issues are adequately addressed towards ensuring condition 22 requirements are fully met. The following needs to addressed as part of condition 22: (a) A potential limitation to the investigation is apparent based on the proposal, and following completion of the proposed investigation any shortcomings from the investigation will have to be addressed to ensure a sufficient investigation has been undertaken in order to adequately complete quantitative risk assessment. This includes the limiting of the current ground gas monitoring to three round to the south east of the site and the absence of any ground gas/vapour monitoring to the north of the site due to site constraints. (b) The indoor continuous monitoring appears to be limited to methane and TVOCs. It is recommended indoor monitoring of gases include all likely gases that need to be considered, including hydrogen sulphide (based on sewer pipe and manhole cover indicated in the basement area). The use of thermal desorption tubes to speciate VOCs is noted. (c) Please ensure any the PID screening data is provided in the report to discharge condition 22. Valid calibration certificates for the equipment used to complete the ground gas and vapour monitoring, with relevant lamp details should be included in the report to discharge condition 22. (d) Any groundwater source vapour risk assessment using SOBRA (2017) would have to clearly set out the site specific conditions and compare it to the modelled SOBRA conditions to demonstrate it is appropriate and at the very least suitably conservative criteria to use. The risk assessment as a whole still needs to consider all sources vapour identified in the PRA. (e) Prior to completing the site investigation, it is recommended the limit of detection achievable, particularly with regard to VOCs is checked with the laboratory to ensure it is as low as practicable and below the appropriate contamination criteria used for soils and groundwater. (f) Table 1: Generic Assessment Criteria for soil samples collected in area of soft landscaping - it is noted not all the criteria in the table are suitable for soils used for landscaping purposes. It is recommended in addition to the risk based criteria in the table a total capped value for TPHs and PAHs is used to prevent gross contamination remaining untreated for onsite and imported soils. A total TPH capped value of 500 mg/kg and Total PAHs capped value of 20 mg/kg is recommended. A note to the criteria table should make clear how these values are to be used alongside the risk based values. Please contact the Environmental Quality Unit ([email protected]) for further clarification on requirements.

CONTAMINATION INFORMATIVE 2 The applicant is reminded that condition 23 (Contamination - Remediation Method Statement) remains to be discharged until a sufficient site investigation and quantitative risk assessment report is submitted in accordance with the requirements of the condition 22 and a remediation method statement based on the findings of the risk assessment and the requirements of condition 24 (Verification Report) relevant to the final development is submitted and approved by this authority. The applicant needs to ensure the consultants are aware of issues identified in the submissions for condition 21 (letter from Fairhurst for 66-74 Notting Hill Gate - Scheme of Investigation (Ref: CB/HB/117485/NHG/SchemeofInvestigation/RevA), dated 22 November 2018) and these issues are adequately addressed towards ensuring condition 23 requirements are fully met. The following also needs to addressed as part of condition 23: (a) Details of any proposed works relating to water supply pipes investigation, where this has not been completed, and verification information be provided in due course needs to be clearly set out in the remediation method statement and verification plan. (b) Details of any soils/materials to be imported to site as part of completing any landscaping works including green roofs and details of how it will be verified needs to be clearly set out in the remediation method statement and verification plan. Site won soil or soil imported on to the site which is to be used for planting, landscaped areas (including under paved areas) and green roofs, shall be sampled at an agreed frequency (1 per 20m3 for onsite soils and 1 per 50m3 for imported soils as a minimum) and analysed for contamination against appropriate contamination criteria for landscaping soils. The criteria in the site investigation scheme is not suitable for all contaminants will have to be updated as part of the remediation method statement submission. A verification plan needs to make clear information including sampling locations/depth, landscaping depth verification, the results of the contamination analysis, soil provenance details and any other supporting information shall be submitted as part of the verification report in due course. (c) Addressing any potential residual risks based on the limitations of the investigation will need to be clearly set out in the remediation method statement and verification plan including sealing off of any potential preferential pathways. Please contact the Environmental Quality Unit ([email protected]) for further clarification on requirements.
