Discharge of Conditions 7 & 8 of LA06/2021/0834/F: 7. All remediation measures as outlined in Section 6 of the Stratex Report, 12 Prospect Road Ballygowan, Preliminary Risk Assessment and Generic Quantitative Risk Assessment referenced no. 18-1162 and dated 15th June 2021 must be undertaken. The applicant shall undertake additional soil sampling at and around the area of TP6 to delineate the extent of the hydrocarbon and PAH contamination within the shallow soils. Samples should be submitted to an accredited UK laboratory and screened against relevant GACs for a residential with plant uptake standard. Samples should be taken from depths of 0.0-1.0mbgl. An appropriate capping system shall then be installed within the garden and landscaped areas confirmed from analysis. A minimum capping system shall be 800mm dept within the gardens of all houses within this area with a minimum of a 250mm crushed stone capillary break at the base overlain with clean subsoils and topsoil. A 600mm capping system is recommended in landscaping areas with a minimum of 200mm crushed stone capillary break in the base overlain with subsoil and topsoil. Install hydrocarbon vapour protection measures within any buildings that may be within the area identified in Figure 6 as a minimum based on the development plans provided within Figure 3. These protection measures should be incorporated into the proposed building floor designs for all properties within this area: • Provision of hydrocarbon vapour protection measures appropriate to prevent vapour intrusion within residential properties. • Concrete floor slabs (precast) with joins sealed and seals around any service entries. • Installation of a specific hydrocarbon vapour proof membrane suitable for hydrocarbon contaminants. The membrane should be hydrocarbon vapour proof, the membrane installed shall withstand the construction process. All joints and service penetrations should be lapped and sealed, and any other manufacturer's recommendations are adhered to. • A passive sub floor ventilation (minimum 150mm sub floor void) to achieve a minimum of one complete air change a day. 8. On completion of the remediation and prior to the occupation of the proposed development, the applicant shall provide to Council, for approval, a Verification Report. This report shall demonstrate the successful completion of remediation works and demonstrate that the site is now fit for end-use and include details of: • Capping system , • The Methodology and programme of the capping system. • Photographs and records of any excavation works within the source area including photographs showing depths to accommodate the capping layer. • Photographs of the clean material being used and placed on the source area, also showing depths being placed. • Records and photographs showing the depth of the capping system as required. • Details of the materials that were used for the capping system along with laboratory certificates and results which confirm that the materials for suitable for use • Hydrocarbon vapour protection measures • Final design of the hydrocarbon vapour protection measures along with any relevant calculations. • Specifications of membrane type and joint tape. • Records of the installation process including all inspections completed by a suitably qualified person. • Photographic and documented records installation and inspection results of each installation on a property-by-property basis.
