Crossrail will support and maintain the status of London as a world city by providing a world class transport system. The project includes the construction of a twin-bore tunnel on an east-west alignment under central London and the upgrading of existing National Rail lines to the east and west of central London. The Crossrail route is shown in Figure 1.1. Figure 1-1: Overview of Crossrail Route The project will enable the introduction of a range of new and improved rail journeys into and through London. It includes the construction of seven central area stations, providing interchange with London Underground, National Rail and London bus services, and the upgrading or renewal of existing stations outside central London. Crossrail will provide fast, efficient and convenient rail access to the West End and the City by linking existing routes from Shenfield and Abbey Wood in the east with Maidenhead and Heathrow in the west. Crossrail will be a significant addition to the transport infrastructure of London and the southeast of England. It will deliver improved services for rail users through the relief of 1 Report Volume I of IV (Feb 2005) Assessment of Atmospheric and Air Quality Impacts Mott MacDonald Technical Report CLRL Limited Volume I of IV crowding, faster journeys and the provision of a range of new direct journey opportunities. The project will also have wider social and economic benefits for London and the southeast of England. 1.1.2 Route Overview Crossrail’s route has four distinct sections: a central section within central London and, outside central London, western, northeastern and southeastern sections. The boundaries of these route sections are shown in the schematic maps in Chapters 4 to 7. In the west, Crossrail will use the Great Western Main Line between Maidenhead and Westbourne Park. The existing 25 kV overhead electrification between Paddington and Airport Junction will be extended to Maidenhead and bridge alterations will be undertaken as necessary. The main infrastructure changes are the construction of a flyover structure (the Stockley flyover) to allow Crossrail trains to access the existing tunnelled spur to Heathrow and the provision of a rail underpass (a dive-under) west of Acton Yard. A new line, within the existing railway corridor, will be provided between Langley and West Drayton. Enhancements will also be made to stations, with the most significant works being at Ealing Broadway, Southall, Hayes and Harlington, West Drayton, Slough and Maidenhead. New stabling sidings are also proposed at Old Oak Common, West Drayton and west of Maidenhead station. The central route section will consist largely of a twin-bore tunnel beneath central London with portals at Royal Oak in the west, Pudding Mill Lane in the northeast and Victoria Dock Road in the southeast. The central route section extends from a point around 200m west of the A40 Westway to a point around 500m to the east of the portal at Pudding Mill Lane in the northeast and a point just to the east of Poplar Dock and the A1206 Prestons Road in the Isle of Dogs in the southeast. New stations and associated structures, such as ventilation shafts, will be provided along this part of the route. On the northeast route section, Crossrail will use the existing Great Eastern Main Line between Pudding Mill Lane and Shenfield. The main infrastructure changes are a new train maintenance depot west of Romford station and the reinstatement of a track between Goodmayes and Chadwell Heath. Enhancements will also be made to stations, with the most significant works being proposed at Ilford and Romford. This route has existing 25kV overhead electrification. New stabling facilities will be provided at Gidea Park. The southeast route section runs between a point to the east of the Isle of Dogs station and the eastern terminus at Abbey Wood, where Crossrail will serve a reconstructed station. Crossrail will operate in a twin-bore tunnel to Victoria Dock portal where it will serve a reconstructed station at Custom House. The route will then follow the existing alignment currently used by the North London Line through the Connaught Tunnel to Silvertown. At North Woolwich, a new twin-bore tunnel to Plumstead, referred to as the Thames Tunnel, will pass beneath the River Thames. Two new tracks will be provided between Plumstead and a point east of Abbey Wood station to accommodate Crossrail services on the North Kent Line corridor. This route will be provided with 25kV overhead electrification on the Crossrail lines. 2 Report Volume I of IV (Feb 2005) Assessment of Atmospheric and Air Quality Impacts Mott MacDonald Technical Report CLRL Limited Volume I of IV 1.2 Reporting Structure Air quality and emissions reporting consists of four volumes: • Volume I – Air quality and emissions report. • Volume II – Air quality and emissions supporting figures. • Volume III – Air quality and emissions assessment input data and assumptions. • Volume IV – Electromagnetic field analysis report. This report, Volume I, is structured as follows: • Section 2 – outlines the methodology, scope and evaluation criteria applied during the assessment. • Section 3 – presents the results of the route-wide assessment of emissions and the route-wide assessment of worksite dust risk. • Section 4, 5, 6 and 7 – present the local air quality and worksite dust assessment by route window for each section of the route. • Section 8 – outlines the dust impacts for the excavated material handling facility at Pitsea. • Section 9 – outlines some potential mitigation measures. • Appendix A – Glossary • Appendix B – References • Appendix C – Uncertainty Analysis – Emissions • Appendix D – Ventilation Shaft Emissions Assessment • Appendix E – Utility Works – Scoping Assessment Results This Report has been produced based on the Environmental Statement Scheme Description Version A1.8 and traffic data files as per the table below: Central construction TN701_B_Traffic Data Construction_(Central)_050126 Rounded.xls NE construction TN702_A_Traffic Data Construction_(North Eastern)_050126 Rounded.xls SE construction TN703_A_Traffic Data Construction_(South Eastern)_050126 Rounded.xls West construction Western_Air_Noise101104.xls Route-wide operation Flow Data for Specialists_Sept04b.xls 3 Report Volume I of IV (Feb 2005) Assessment of Atmospheric and Air Quality Impacts Mott MacDonald Technical Report CLRL Limited Volume I of IV (This page left intentionally blank). 4 Report Volume I of IV (Feb 2005) Assessment of Atmospheric and Air Quality Impacts Mott MacDonald Technical Report CLRL Limited Volume I of IV 2 Context, Scope and Methodology 2.1 Introduction 2.1.1 Context The primary focus of this section is to describe the scope and methodology for the assessment of atmospheric impacts. Before considering the methodology in any more detail first the context of regulation in these areas is outlined.
