Our combined Updating and Screening Assessment (USA) integrates the Local Air Quality Management (LAQM) reporting duties for our former District Councils into a single document. This document is structured in such a way that Updating and Screening Assessment data for the former District Council areas are reported in individual chapters. For reporting purposes, it should be noted that: • Kennet – refers to the former Kennet District Council area; • North Wiltshire – refers to the former North Wiltshire District Council area; • Salisbury – refers to the former Salisbury District Council area; and • West Wiltshire – refers to the former West Wiltshire District Council area. There are currently five Air Quality Management Areas within the Wiltshire Council administrative area, these are: • Whole city centre AQMA in the Salisbury area; • London Road (near St Mark’s roundabout) in the Salisbury area; • Wilton Road (near St Paul’s roundabout) in the Salisbury area; • Bradford on Avon in the West Wiltshire area; and • Westbury in the West Wiltshire area. This combined Updating and Screening Assessment for 2009 has concluded the following: • Kennet area – Monitoring data has indicated exceedences of the NO2 annual mean objective at Upper Herd Street and Shane’s Castle – both of these locations are being considered in an ongoing Detailed Assessment. No new Detailed Assessment is required based on monitoring data or the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern. • North Wiltshire area - No Detailed Assessment is required based on monitoring data or the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern. • Salisbury area - Monitoring data has indicated exceedences of the NO2 annual mean objective in the Salisbury AQMAs in 2006, 2007 and 2008, therefore, the AQMAs are still justified. There was one exceedence of the iii Wiltshire Council – Updating and Screening Assessment 2009 NO2 annual mean objective outside of the current AQMAs, therefore, a Detailed Assessment is required at Queen Street, Wilton. No Detailed Assessment is required based on the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern. • West Wiltshire area - Monitoring data has indicated exceedences of the NO2 annual mean objective have in the Bradford on Avon and Westbury AQMAs in 2006, 2007 and 2008, therefore, the AQMAs are still justified. There were no exceedence of the NO2 annual mean objective outside of the current AQMAs, therefore, no Detailed Assessment is required. No Detailed Assessment is required based on the assessment of sources. Previous rounds of Review and Assessment has indicated that there are no other pollutants of concern. Proposed actions for subsequent Review and Assessment reporting duties will include: • Completion and submission of the ongoing Upper Herd Street and Shane’s Castle Detailed Assessment for NO2 (annual mean objective); • Completion and submission of the Queen Street, Wilton Detailed Assessment for NO2 (annual mean objective) in 2010; • Completion and Submission of a Review and Assessment Progress Report in 2010; and • Completion and Submission of a Air Quality Action Plan Progress Report in 2010 (this may be integrated in to the Review and Assessment Progress Report). iv Wiltshire Council – Updating and Screening Assessment 2009 Table of Contents Document Control Sheet ii Executive Summary iii Table of Contents v List of Figures vii List of Tables ix 1 Chapter 1 -
