2014 Air Quality Progress Report for Chelmsford City Council In fulfillment of Part IV of the Environment Act 1995 Local Air Quality Management June 2014 1 Local Authority Officer Tim Savage Department Public Health & Protection Services Duke Street Chelmsford Address Essex CM1 1JE Telephone 01245 606264 Email [email protected] Report Reference CCC/PR2014 number Date 25th June 2014 Written by Tim Savage Approved by Gary Lewis Scientific Team Public Health & Protection Services Chelmsford City Council Duke Street Chelmsford Essex CM1 1JE 2 Executive Summary The 2014 Progress Report is designed to fulfil Chelmsford City Councils statutory duty to review and assess air quality within its area, and to determine whether or not the air quality objectives are likely to be achieved. Air Quality within AQMAs Chelmsford City Council has one Air Quality Management Area (AQMA) in the vicinity of the Army and Navy roundabout. Automatic monitoring measured an exceedance of the nitrogen dioxide annual mean air quality objective however there was no exceedance at relevant exposure. No exceedences of the one hour mean objective were measured. Non automatic monitoring measured an exceedance of the nitrogen dioxide annual mean air quality objective at one location which was at relevant exposure. Air Quality outside AQMAs Automatic monitoring measured no exceedences of the air quality objectives for nitrogen dioxide, particulate matter (PM10) or sulphur dioxide. Non-Automatic monitoring measured an exceedance of the nitrogen dioxide annual mean air quality objective at one location but there was no exceedance at relevant exposure. However, it should be noted that at four locations, borderline concentrations (36-40 µg/m 3) were identified. 3 Table of Contents 1 Introduction 7 1.1 Description of Local Authority Area 7 1.2 Purpose of Progress Report 8 1.3 Air Quality Objectives 8 1.4 Summary of Previous Review and Assessments 10 2 New Monitoring Data 11 2.1 Summary of Monitoring Undertaken 11 2.2 Comparison of Monitoring Results with Air Quality Objectives 16 3 New Local Developments 29 4 Local / Regional Air Quality Strategy 30 5 Planning Applications 31 6 Air Quality Planning Policies 32 7 Local Transport Plans and Strategies 33 8 Climate Change Strategies 35 9 Implementation of Action Plans 36 10 Conclusions and Proposed Actions 39 10.1 Conclusions from New Monitoring Data 39 10.2 Proposed Actions 39 11 References 40 12 Appendices 42 4 List of Tables Table 1.1 Air Quality Objectives included in Regulations for the purpose of LAQM in England.

The City of Chelmsford comprises a number of suburban areas around these main urban areas and in the larger villages of Danbury, East and West Hanningfield, Great Leighs, Little Waltham and Little Baddow, within a rural setting. The main source of air pollution in Chelmsford is road traffic emissions from major roads, notably the A12, A414, A138, A130 and B1016. Other pollution sources, including commercial, industrial and domestic sources, also make a contribution to background pollution concentrations. Chelmsford City Council has declared one Air Quality Management Area (AQMA) in November 2005. • Army & Navy Roundabout Based on monitoring results from 2008 to 2011, the Detailed Assessment conducted in April 2010 and the USA in 2012, the AQMA was reduced in size in 2012.

Chelmsford CC Licence No. 10002356 2 2014 7 1.2 Purpose of Progress Report This report fulfils the requirements of the Local Air Quality Management (LAQM) process as set out in Part IV of the Environment Act (1995), the Air Quality Strategy for England, Scotland, Wales and Northern Ireland 2007 and the relevant Policy and Technical Guidance documents. The LAQM process places an obligation on all local authorities to regularly review and assess air quality in their areas, and to determine whether or not the air quality objectives are likely to be achieved. Where exceedences are considered likely, the local authority must then declare an Air Quality Management Area (AQMA) and prepare an Air Quality Action Plan (AQAP) setting out the measures it intends to put in place in pursuit of the objectives. Progress Reports are required in the intervening years between the three-yearly Updating and Screening Assessment reports. Their purpose is to maintain continuity in the LAQM process. They are not intended to be as detailed as Updating and Screening Assessment Reports, or to require as much effort. However, if the Progress Report identifies the risk of exceedence of an Air Quality Objective, then the Local Authority (LA) should undertake a Detailed Assessment immediately, and not wait until the next round of Review and Assessment. 1.3 Air Quality Objectives The air quality objectives applicable to LAQM in England are set out in the Air Quality (England) Regulations 2000 (SI 928), The Air Quality (England) (Amendment) Regulations 2002 (SI 3043), and are shown in Table 1.1. This table shows the objectives in units of microgrammes per cubic metre µg/m3 (milligrammes per cubic metre, mg/m3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable). 8 Table 1.1 Air Quality Objectives included in Regulations for the purpose of LAQM in England Air Quality Objective Date to be Pollutant Concentration Measured as achieved by Running annual 16.25 µg/m 3 31.12.2003 Benzene mean 5.00 µg/m 3 Annual mean 31.12.2010 Running annual 1,3-Butadiene 2.25 µg/m 3 31.12.2003 mean Running 8-hour Carbon monoxide 10 mg/m 3 31.12.2003
