The main towns are Maldon, Heybridge, Southminster, Burnham on Crouch and the District has a population of 62,400 (ONS, 2008). 1.2 Purpose of Progress Report 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 Local Air Quality Management 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, 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 Local Air Quality Management (LAQM) in England are set out in the Air Quality (England) Regulations 2000 (SI 928), and the Air Quality (England) (Amendment) Regulations 2002 (SI 3043). They are shown in Table 1.1. This table shows the objectives in units of microgrammes per cubic metre g/m3 (for carbon monoxide the units used are milligrammes per cubic metre, mg/m3). Table 1.1. includes the number of permitted exceedences in any given year (where applicable). 6 Progress Report Maldon District Council – England Date April 2010 Table 1.1 Air Quality Objectives included in Regulations for the purpose of Local Air Quality Management in England.

The first round assessments concluded that air quality objectives for all pollutants would be achieved by their target date, and that no AQMA’s would be necessary at that time. The second round of review and assessment, the USA, was undertaken from 2003 to 2005 and provided an update with respect to seven LAQM pollutants within the district of Maldon. The USA concluded that objectives would be met by their target dates with no exceedences; however, it was recommended that the diffusion tube monitoring programme be expanded to include receptors close to busy road junctions in order to confirm the findings of the USA with respect to NO2. The 2005 Progress Report (Maldon, 2005) concluded that Maldon Council was continuing to meet the air quality objectives and that detailed assessments were not necessary. The 2006 USA revised the previous results and again found there was no risk of exceedence of air quality objectives within the Maldon District, and therefore concluded that a Detailed Assessment was not required. In 2007 Maldon District Council undertook a short term monitoring study at Beckingham Business Park to check for exceedences of NO2 resulting from transport activity at the site. NO2 diffusion tubes deployed at the site illustrate concentrations well below the annual mean objective, therefore continued monitoring was considered unnecessary and diffusion tubes were removed at the end of the 2007 financial year. This was followed by the 2008 Progress Report, which again concluded that there was no risk of exceeding air quality objectives by the relevant target dates, and that there was no requirement for any detailed assessments. The 2009 USA review of 2008 monitoring data, showed that there were no exceedences of the air quality objectives in Maldon in 2008 and no requirement to proceed to a Detailed Assessment for any pollutant.

Details of Non- Automatic Monitoring Sites o The diffusion tubes are supplied and analysed by Environmental Scientific Groups/ Bureau Veritas o Preparation method : 20% Triethanolamine (TEA) in water o United Kingdom Accreditation Services (Testing Laboratory number 0023).

In the absence of a local bias correction factor, the default bias correction factor for Environmental Scientific Groups analysis using the 20% TEA in water method. This factor, calculated as 0.77 for 2009 based on 1 study and should be used with caution which has been obtained from the University of the West of England (UWE) website1. 1 http://www.uwe.ac.uk/aqm/review/R&Asupport/ Progress Report 9 Date April 2010 Maldon District Council - England Figure 2.1 Map of Non-Automatic Monitoring Sites Maldon District Council Diffusion tube locations 2009 10 Progress Report Maldon District Council – England Date April 2010 Table 2.1 Details of Non- Automatic Monitoring Sites Relevant Distance To Exposure?
