4 1. Introduction This Progress Report is a requirement of the Environment Act 1995, Part IV, which places a duty on local authorities to periodically review and assess air quality within their location. The Progress Report follows on from the Updating and Screening Assessment (USA) which was carried out in 2003 as part of the second round of Review and Assessment. The USA report concluded that there is currently no risk of exceeding any of the air quality objectives and that a detailed assessment is not required for the current round of Review and Assessment. The objective of the Progress Report is to provide continuity in the Local Air Quality Management process by reporting any potential changes in air quality that may occur between the three yearly review and assessments of air quality. This report has been compiled with reference to the Progress Report Guidance (LAQM.PRG(03)) which was published by DeFRA in It presents information which has been collated since the production of the USA report, including: air quality monitoring data, information about emission sources and any proposed developments which have the potential to affect air quality in the District. Outcomes of previous Review and Assessments for Maldon Maldon Council undertook their First Round of review and assessment, including Stage 1 and Stage 2 reports, between 1999 and The results of the First Round predicted that the air quality objectives should be met by their target dates and that it was therefore not necessary to declare any Air Quality Management Areas (AQMA) for any pollutant. The main air quality issues were found to be emissions of NO 2 and PM 10 from vehicles on the A414. The USA reconsidered the seven health based air quality objectives and concluded that there was still no risk of exceedance. Therefore, there is no requirement to carry out a detailed assessment for the Second Round of Review and Assessment. 1

5 2. Monitoring data Maldon District Council measures air quality in the district using passive diffusion tubes at three locations, as shown in figure 2.1. The results of the monitoring programme are summarised in table 2.1 below. Table 2.1 Nitrogen dioxide diffusion tube monitoring results (NO 2 in µg/m 3 ). ID Location Site Type 2002 NO 2 Bias applied 2003 NO 2 Bias applied MD1 Opposite Cherry Oak, A414 Roadside 39.9* 37.1* 35.2 MD2 Wycke Hill A141, Wincroft Roadside 37.1* 33.7* 31.9 MD3 Heybridge Approach, A141 Roadside 29.1* 33.8* 32.0 *Data capture < 75% (9 months) Projected 2005 NO 2 (from 2003) The diffusion tubes used by Maldon District Council are supplied and analysed by Casella Seal utilising the 10% TEA 1 in water preparation method. Casella Seal participate in the Workplace Analysis Scheme for Proficiency (WASP) for NO 2 diffusion tube analysis and the Annual Field Inter-Comparison Exercise (Lab 13). A recent study 2 investigating the performance of diffusion tubes supplied by different laboratories throughout the UK, found that there was a slight underread of 5.6% using this laboratory at a background site in Derby. Technical Guidance (LAQM.TG (03)) recommends co-location of diffusion tubes with an automatic analyser to ensure the accurate reporting of concentrations, with any positive or negative local bias taken into account. In the absence of colocation in Maldon, a precautionary approach has been taken and the results have been bias adjusted by the reported under-read of 5.6%. There are no current or predicted exceedences of the NO 2 annual mean objective, at any of the current monitoring locations. There are insufficient years of data to comment on long term trends of nitrogen dioxide in Maldon. The diffusion tube monitoring programme is being expanded this year to include five additional monitoring locations, which were identified as requiring monitoring in the Updating and Screening Assessment. The results from these sites will be reported in the 2005 Annual Progress Report. 1 TEA-Triethanolamine 2 Laxen DPH (2002) Compilation of diffusion tube co-location studies carried out by local authorities.

7 3. Emission sources When the Updating and Screening Assessment was carried out in 2003, there were no Part A industrial sources and 17 Part B industrial sources (of which, 5 were petrol stations) in the district of Maldon. These are listed in Table 3.1. Since the USA was carried out, one new process has commenced operating and one process has ceased to operate. In addition, four processes are currently being considered for authorisation. These are shown in table 3.1. Additional information about changes to existing processes are listed in the Notes column of table 3.1.

8 4. Planning and Policies There are currently no planning applications for new developments for which air quality assessment is required. 5. Local Transport Plan Maldon District is covered by the Essex County Council Local Transport Plan. There are a number of general measures in the Essex LTP which are aimed at reducing the impact of road transport on air quality. The District Council are working in partnership with the Highways and Transportation department to ensure that new traffic management schemes consider the potential impact on air quality. Introducing additional air quality monitoring programmes as part of the monitoring requirements of the LTP. 6. Summary and Conclusions The Progress Report shows that Maldon District is currently meeting the air quality objectives and is not at risk of exceeding the objectives by the relevant target dates. The District Council is working in partnership with key stakeholders to ensure that the air quality in Maldon remains below objective limits and continues to improve. The expansion of the monitoring network will improve the data availability in the District. All new monitoring data will be reported in the 2005 Progress Report. The District Council does not need to carry out any detailed assessment as a result of any findings of the Progress Report. The next air quality report to be prepared and submitted to DeFRA will be the 2005 Progress Report. 5
