London Borough of Hillingdon 100019283 2013 Aerial Photography © 2012 BLOM Published by: Environmental Protection Unit Residents Services London Borough of Hillingdon 3S/02 Civic Centre High Street, Uxbridge Middlesex UB8 1UW January 2014 ii London Borough of Hillingdon Contaminated Land Inspection Strategy 2013-2018 Executive Summary The Contaminated Land Inspection Strategy was published in July 2001. This document outlined how the London Borough of Hillingdon would carry out its statutory duties in collating and reviewing information on land which may have contamination issues, in order to identify contaminated land in the borough under Part IIA. Members of the Cabinet approved some revisions to the implementation of the strategy in September 2005. The third strategy review follows in the wake of the second revision to the Contaminated Land Statutory Guidance published in 2012 by DEFRA (Department of the Environment, Food and Rural Affairs) with the aim to clarify the approach for identifying and determining contaminated land. This review brings the original strategy document up to date by highlighting any changes in legislation and guidance, reporting on the progress made in implementing the strategy and identifying the work that remains to be completed. The priorities of the strategy remain the same. These are: 1. To protect human health 2. To protect controlled waters 3. To protect designated ecosystems 4. To prevent damage to property 5. To prevent any further contamination of land 6. To encourage voluntary remediation 7. To encourage reuse of brownfield land The aims of the strategy were updated in 2007 and have been integrated into Council policies where possible, remain as follows: 1. To fulfil the Council’s duties under the Part IIA legislation 2. To bring about environmental improvements to create a clean and attractive borough 3. To encourage voluntary remediation and the reuse of brownfield land 4. To limit the impact of contamination from Council owned land 5. To raise awareness and promote understanding of land contamination issues The work relating to these aims remain complex. The strategy review focuses specifically on how the strategic inspection work is being implemented by the Environmental Protection Unit (EPU), providing details on how information on sites is collected, and used to prioritise the sites for strategic inspection and determine if further detailed investigation is required. Details of the Council’s approach to the determination and remediation of contaminated land will be provided in the Contaminated Land Remediation Strategy in due course. However, Chapter 8 of this document summarises some of the land contamination investigation and remedial work undertaken in the borough over the last decade, including at the only site determined contaminated land under Part IIA, and designated a special site. The strategy review also highlights the importance of working together with other sections of the Council to achieve the aims of the strategy, primarily by sharing information, and the contributions other sections of the Council make in managing land contamination matters in Hillingdon. As intended, the Planning regime (Development Management) continues to be the main avenue for bringing about the voluntary remediation of contaminated land. In accordance with the revised statutory guidance 2012 this strategy and its progress will be reviewed in 5 years and effort will be made to ensure that the principles of this strategy inform any future strategic plans and policies for the borough. Note: Formal consultation with statutory/specialist consultees (Appendix 3), stakeholders (Appendix 4) and the wider public was undertaken prior to publishing the final document. Consultation responses received are included in Appendix 5. iii London Borough of Hillingdon Contaminated Land Inspection Strategy 2013-2018 Table of Contents Document Control, Acknowledgements, Copyright ii Executive Summary iii Table of Contents iv Chapter 1 – Introduction to Part IIA & Council Policy 1 1.0 Introduction 1 1.1 Regulatory Context 3 1.2 Definition of Contaminated Land 4 1.3 Government Objectives for Implementing Part IIA 4 1.4 General Local Authority Policies & Functions 4 1.4.1 Hillingdon’s Sustainable Community Strategy 2011 5 1.4.2 Public Health Policy 5 1.4.3 Development Management 5 1.5 Part IIA Enforcement & Hardship Policies 6 1.6 Interaction of Part IIA with Other Regimes 6 1.7 Progress of the Strategy 6 Chapter 2 – Characteristics of the London Borough of Hillingdon 8 2.0 Introduction 8 2.1 Current Land Use Characteristics 8 2.2 Industrial History and Potential Contamination 10 2.3 Nature Conservation Areas 13 2.4 Protected Property 14 2.5 Protection of Controlled Waters 16 2.6 General Geological and Hydrogeological Characteristics 18 2.7 Local Authority Ownership of Land 19 Chapter 3 – Aims, Objectives & Priorities of the Inspection Strategy 21 3.0 Introduction 21 3.1 To fulfil the Council’s duties under the Part IIA legislation 21 3.2 To bring about environmental improvements to create a clean, 21 attractive borough 3.3 To encourage voluntary remediation and the reuse of brownfield land 22 3.4 Limiting the impact of contamination from Council owned land 22 3.5 To raise awareness and promote understanding of land contamination 22 issues 3.6 Priority Timescales 23 3.7 Review of the Inspection Strategy 24 Chapter 4 – Prioritisation of Sites for Inspection 25 4.0 Introduction 25 4.1 Information Collection 25 4.1.1 Information on the Sources of Potential Contamination 25 4.1.2 Information on Potential Pathways for Contamination 25 4.1.3 Information on Potential Receptors 26 4.2 Prioritisation using the GroundView Site Prioritisation Tool 28 4.3 Carrying out Strategic Inspections – Initial Risk Assessment 29 iv London Borough of Hillingdon Contaminated Land Inspection Strategy 2013-2018 4.4 Carrying out Detailed Inspections – Detailed Risk Assessment 31 4.5 Powers of Entry onto Land 33 4.6 Special Considerations with Respect to Site Investigations 34 4.6.1 Controlled Waters and Potential Special Sites 34 4.6.2 Nature Conservation Sites 34 4.6.3 Sites of Archaeological & Historical Significance 34 4.6.4 Contamination affecting Agricultural Land, Property & Foodstuffs 34 4.7 Monitoring the Progress of the Strategic Inspection Work 34 4.8 Funding for Part IIA Investigation 35 4.9 Re-Inspecting Land 35 Chapter 5 – Management of Land Contamination Matters 36 5.0 Introduction 36 5.1 Responsibilities of the Contaminated Land Officer 37 5.2 Responsibilities within Development Management & Building Control 38 5.3 Responsibilities of the Council as Land Owner 39 5.4 Consulting Legal Services 41 5.5 The Contaminated Land Remediation Strategy 41 Chapter 6 – General Liaison & Communication 42 6.0 Introduction 42 6.1 Statutory/Specialist Consultees 42 6.2 Non-statutory Consultees 42 6.3 Communicating with Interested Parties 42 6.4 Provision of Information to the Environment Agency 43 6.5 Risk Communication 43 6.6 Press and Media 44 Chapter 7 – Information Management 45 7.0 Introduction 45 7.1 Information and Complaints 45 7.2 Storage of Information 45 7.3 Updating and Maintenance of Information 45 7.4 Internal Access to Information 46 7.5 Public Access to Information 46 7.5.1 The Contaminated Land Public Register 46 7.5.2 Land Contamination Enquiries 47 7.6 Confidentiality 47 Chapter 8 – Remediation of Contaminated Land 48 8.0 Introduction 48 8.1 Remediation under Part IIA: Former New Years Green Lane Landfill 48 8.2 Voluntary Remediation under Development Management (Planning) 49 8.2.1 Taylor Woodrow Sports Club/Willow Tree Lane Landfill 49 8.2.2 Former Astor Chemicals Site 49 8.2.3 Uxbridge Gas Works Site 49 8.2.4 Retained National Air Traffic Control Services Site 50 8.2.5 Technicolor Site (Film Laboratory) 50 8.3 Voluntary Remedial Works & Risk Management 50 8.3.1 British Benzol Fuel Spill 50 8.3.2 Willow Piggeries, Part of Prospect Park 51 8.3.3 Dawes Road, RAF Uxbridge 51 v London Borough of Hillingdon Contaminated Land Inspection Strategy 2013-2018 References/Bibliography 52 Appendices 1 Appendix 1: Acronyms and Glossary of Terms 2 Appendix 2: Interaction of Part IIA with Other Regimes 12
