Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQExecutive SummaryBureau Veritas HS&E have been commissioned by Rochford District Council to undertakethree months fine particles (PM 10 ) monitoring at Rawreth Industrial Estate, Rayleigh, Essexand assess concentrations against UK air quality objectives for PM 10 . This assessmentbuilds upon the findings of the 2005 Detailed Assessment of PM 10 emissions from RawrethIndustrial Estate. The recent PM 10 monitoring conducted in 2007 has been considered inconjunction with the 2004 and 2005 monitoring data to aid the conclusions of thisassessment.The periods of monitored PM 10 data were annualised in accordance with LAQM.TG (03).The annualised PM 10 results indicate that exceedences of the 24-hour mean Objective mayoccur. There are predicted to be greater than 35 exceedences of 50µg/m 3 over the year,which can be largely attributed to local fugitive emissions sources.It is recommended that Rochford District Council consider declaring an Air QualityManagement Area (AQMA) on the basis of the potential exceedences in the Rawrethassessment area as highlighted in this assessment where exposure criteria are fulfilled. It isalso recommended that the Council consider installing a permanent PM 10 monitoring stationin the vicinity of the Rawreth Industrial Estate to enable continued assessment ofcompliance with the 24-hour mean Objective.Bureau Veritas Air Quality 1


Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQ1 Introduction1.1 Project BackgroundBureau Veritas HS&E have been commissioned by Rochford District Council to undertakethree months PM 10 Monitoring at Rawreth Industrial Estate, Rayleigh, Essex and assessconcentrations against UK air quality objectives.This assessment for fine particles (PM 10 ) builds upon the findings of the 2005 DetailedAssessment of PM 10 emissions from Rawreth Industrial Estate. The additional PM 10monitoring conducted in 2007 will be considered in conjunction with the 2004 and 2005monitoring data to aid the conclusions of this assessment.1.2 Legislative Background1.2.1 Air Quality Strategy ObjectivesPart IV of the Environment Act, 1995, places a statutory duty on local authorities toperiodically review and assess the air quality within their area. This involves considerationof present and likely future air quality against air quality standards and objectives.The Air Quality Strategy for England, Scotland, Wales and Northern Ireland (AQS) 1 (alongwith its addendum 2 ) contains national air quality standards and objectives established bythe Government to protect human health. The objectives for seven pollutants have beenprescribed within the Air Quality (England) Regulations 2000 3 and the Air Quality (England)(Amendment) Regulations 2002 4 (benzene, 1,3-butadiene, carbon monoxide, lead, nitrogendioxide, sulphur dioxide and particulates). The AQS objectives set in Regulations inEngland are shown in Table 1.1.The Air Quality Standard Regulations 2007 came into force on 15 th February 2007. Thisbrings together in one statutory instrument the Government’s requirements to fulfil separateEU Daughter Directives through a single consolidated statutory instrument, which is fullyaligned with the proposed new EU Air Quality Directive (CAFE) 5 .Provisional objectives set out in the addendum to the AQS for the assessment of PM 10 (inresponse to the proposed EU Limit Values) are not included within the Regulations 2007 asthese are unlikely to be considered further within the proposed new EU Air Quality Directive(CAFE).1 DETR (2000) The Air Quality Strategy for England, Scotland, Wales and Northern Ireland – Working together for Clean Air,The Stationery Office2 Defra (2002) The Air Quality Strategy for England, Scotland, Wales and Northern Ireland: Addendum, The Stationery Office3 DETR (2000) The Air Quality Regulations 2000, The Stationery Office4 Defra (2002) The Air Quality Regulations 2002,The Stationery Office5 http://ec.europa.eu/environment/air/cafe/index.htmBureau Veritas Air Quality 2

The AQS Review has introduced anew approach, exposure reduction, to air quality management for non-threshold pollutants.This approach comprises the following elements for PM 2.5 :• A "concentration cap" of 25µg/m 3 to be achieved by 2020;• An objective based on reducing average exposure across the most heavily populatedareas of the country (15% reduction at urban background sites between 2010 and 2020).The Review proposes that the AQS objectives in Table 1.1 are retained. The Reviewrecommends replacing the provisional 2010 PM 10 objectives with the exposure reductionobjective for PM 2.5 and concentration cap.6 The Air Quality Strategy for England, Scotland, Wales and Northern Ireland.

Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQThe AQS objectives take into account EU Directives that set limit values which memberstates are legally required to achieve by their target dates. The UK’s AQS objectives areequal to, or more stringent than, the EU limit values (no Member State may promulgate airquality standards that are weaker than the EU Limit Values).The locations where the AQS objectives apply are defined as locations outside buildings orother natural or manufactured structures above or below ground where members of thepublic are regularly present and might reasonably be expected to be exposed to pollutantconcentrations over the relevant averaging period of the AQS objective. Typically theseinclude residential properties and schools/care homes for longer period (i.e. annual mean)pollutant objectives and high streets for short-term (i.e. 1-hour) pollutant objectives.1.2.2 Local Air Quality ManagementPart IV of the Environment Act places a statutory duty on local authorities to periodically‘review and assess’ the air quality within their area under the Local Air Quality Management(LAQM) regime. This involves consideration of present and likely future air quality againstthe AQS objectives prescribed within the Air Quality Regulations. Where the LAQM Reviewand Assessment process finds that pollutant concentrations are unlikely to meet the AQSobjectives by their target dates in areas where the AQS objectives apply, the LocalAuthority are required to declare an Air Quality Management Area (AQMA) under Section83(1) of the Environment Act 1995. The areas in which the AQS objectives apply aredefined in the AQS as locations outside buildings or other natural or man-made structuresabove or below ground where members of the public are regularly present and mightreasonably be expected to be exposed to pollutant concentrations over the relevantaveraging period of the AQS objective.Guidelines for the ‘Review and Assessment’ of local air quality were first published in the1997 National Air Quality Strategy (NAQS) 7 along with associated policy guidance andtechnical guidance. The First Round of Review and Assessment recommended that localauthorities fulfil their statutory duty under the LAQM regime by undertaking a three-stageassessment, increasing in detail at each stage.In 2000, Government reviewed the NAQS and published the revised AQS, to which anaddendum was issued in February 2003. Associated revised LAQM Technical Guidance(LAQM.TG(03)) 8 and Policy Guidance (LAQM.PG(03)) 9 were issued on behalf of DEFRA inJanuary 2003. This guidance sets the framework for the requirements of review andassessment for future years, taking account of experiences from the previous rounds ofreview and assessment. This current framework for review and assessment begins with anUpdating and Screening Assessment (USA) that considers the likelihood of all the AQSobjectives being achieved across the Local Authority’s administrative area. If the USAidentifies that an AQS objective may not be met, then the Local Authority must proceed to aDetailed Assessment for that pollutant. If the results of the Detailed Assessment confirmthat, an AQS objective is unlikely to be met they are required to declare an AQMA.Having declared an AQMA the authority is required to confirm the findings of the DetailedAssessment work through further monitoring or modelling assessments.

Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQAssessment should provide information on the source-apportionment of the pollutantemissions in order to identify the level of pollutant reduction required for the attainment ofrelevant air quality objectives. Additionally, consideration should be made to evaluatinglocal management practices that could be used to improve air quality, and feed into theformulation of an Action Plan.The Second Round of Review and Assessment (2003-2005) provided an opportunity forlocal authorities to update the findings of their first round of review and assessment. Indoing so, local authorities were to take into consideration changes in AQS Objectives andrevised Technical Guidance (LAQM.TG(03)), new emission sources, and any significantproposed planning developments due to take place before the relevant AQS Objectivetarget date.Additional guidance has been provided in the form of FAQs and updated LAQM tools inJanuary 2006 to assist with Third Round of Review and Assessment (2006-2008). Thisincludes revised modelled background concentration maps for NO X , NO 2 and PM 10 ,updated future year calculation tools and updates on the assessment of specific sources(rail, shipping, poultry farms).At the time of writing the Review and Assessment process has culminated in thedeclaration of over 200 separate AQMAs across the UK. The results have shown that it isroad traffic emissions that are the main cause of exceedences of two pollutants listed withinthe AQS. Namely, fine particulates (PM10) and nitrogen dioxide (NO2) are the pollutants ofgreatest concern. Whilst other pollutants such as carbon monoxide (CO) and benzene areassociated with road traffic emissions, the latest national perspective on the occurrence ofeach of these pollutants suggests that these are no longer a problem at roadside locationsacross the UK.1.3 Summary of Review and Assessment by Rochford District CouncilRochford District Council undertook their First Round of review and assessment, includingStage 1, 2 and 3 reports, during 1998 – 2001. The First Round predicted that the air qualityObjectives should be met by their target dates. The main issues with respect to local airquality were found to be road traffic emissions (NO 2 and PM 10 ) emanating from vehicles onthe A127 Southend Arterial Road and A130 Chelmsford Road, but it was not necessary todeclare any Air Quality Management Areas (AQMA) for any pollutant at that time.The Second Round of Review and Assessment commenced in 2003 with the Updating andScreening Assessment (USA). Similarly to Stage One of the First Round, there wasconsideration of the seven pollutants of concern to health and an assessment was made asto whether Air Quality Objectives for these pollutants would be met. Rochford DistrictCouncil completed this in October 2003, with the conclusion that a Detailed Assessmentwas required for the PM 10 24-hour Objective at residential properties in the vicinity of theRawreth Industrial Estate where a number of fugitive PM 10 emissions source are located. Itwas also recommended to undertake NO 2 monitoring at the nearest receptors to the A130in Rawreth, the High Street/Eastwood Road junction in Rayleigh and Rochford MarketSquare to confirm compliance with the annual mean NO 2 Objective.A Detailed Assessment was submitted to Defra in November 2004 following the first threemonthmonitoring study. The results indicated that there may be a risk of exceedence of the24 hour mean Objective and it was recommended that further monitoring be undertaken todemonstrate compliance with the Objective.Bureau Veritas Air Quality 5


Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQA second Detailed Assessment was completed in May 2005, following a second period ofPM 10 monitoring at the Rawreth Industrial Estate with the conclusions that the Councilshould consider declaring an AQMA for PM 10 due to fugitive emissions from the industrialestate and that further PM 10 monitoring should be conducted.The Third Round of Review and Assessment commenced in 2006 with the USA. The thirdround USA concluded that a Detailed Assessment is required for NO 2 due to road traffic atRayleigh High Street and Rochford Market Square and for PM 10 due to industrial emissionsat two industrial estates separate to Rawreth Industrial Estate. These issues will beconsidered in a separate Detailed Assessment.Further PM 10 monitoring has been conducted from 25 th April – 24 th July 2007 in the vicinityof Rawreth Industrial Estate. This monitoring data provides the basis for this assessment.1.4 Scope and Methodology of the AssessmentThe scope of this assessment is to identify the impact of fugitive PM 10 emissions fromRawreth Industrial Estate on local sensitive receptors. The assessment follows on from theconclusions of the Rochford 2003 Updating and Screening Assessment and subsequent2004 and 2005 Detailed Assessments, which highlighted the risk of exceedence of thePM 10 24 hour objective at residential properties close to Rawreth Industrial Estate andrecommended that an Air Quality Management Area for PM 10 be declared.This assessment will draw on the results of three (3-month) periods of PM 10 monitoringconducted using a Partisol 2025 gravimetric analyser in May-August 2004, February-May2005 and April-July 2007. The analyser was located in the garden of a residential propertyin Victoria Avenue, west of Rawreth Industrial Estate, during the three monitoring periods.Four key sources of fugitive PM 10 emissions on Rawreth Industrial Estate were identified inthe 2003 USA as potential causes of exceedence of the PM 10 24 hour mean objective atnearby receptors. These potential sources are shown in Table 1.2 and Figure 1.1. It shouldbe noted that there are other potential sources of fugitive PM 10 emissions in the vicinity,such as adjacent arable farming, which will also contribute to elevated measured PM 10concentrations during the drier summer months.Monitoring data derived from the Partisol 2025 analyser has been compared to nearbybackground PM 10 monitoring data from Southend-on-Sea and from Thurrock in order toidentify anomalies and attribute them to a local source.The assessment has been undertaken in accordance with the methodologies provided inthe Technical Guidance (LAQM. TG (03)) 8 .Bureau Veritas Air Quality 6

Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQ2 Local Monitoring Data2.1 PM 10 Partisol 2025 MethodologyA Rupprect & Patashnick Partisol 2025 PM 10 gravimetric analyser was located at a siteadjacent to the Rawreth Industrial Estate in one of the rear gardens of the nearestresidential properties to the site boundary on Victoria Avenue. The industrial estate isbordered to the west and south by residential properties with a 3m buffer zone and a 6mhigh fence lying between the two. The site chosen was to the east of the estate in closeproximity to the T J Cottis site, which has been the main source of reported dustcomplaints. Monitoring was undertaken during May to August 2004, February to May 2005and most recently April to July 2007, to assess fugitive emissions during representativemeteorological conditions in the summer/winter months.The Partisol 2025 is a type-approved gravimetric analyser used widely in the UK air qualitynetwork and allows direct comparison against the current PM 10 Objectives based on afixed 24-hour monitoring period. Filters were conditioned and weighed during the 2004 and2005 monitoring periods by Casella CRE Air, in accordance with EN12341, the referencemethod for gravimetric determinations. Casella CRE Air has UKAS accreditation for thisundertaking. During the 2007 monitoring period, the same process was conducted byBureau Veritas Laboratories. Bureau Veritas hold UKAS accreditation for this process.In order to aid interpretation of the data, a meteorological mast was co-located with thePartisol recording wind direction and wind speed.Bureau Veritas Air Quality 8


Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQ2.2 PM 10 Partisol 2025 ResultsA summary of the key statistics extracted from the three Partisol 2025 monitoring periodsare shown in Table 2.1. The results show a good correlation in terms of the mean andminimum PM 10 concentration measured over the three monitoring periods, with a greaterdiscrepancy in the maximum PM 10 and number of exceedences of the 24 hour mean PM 10measured. The second monitoring period, from February to May 2005 displays the highestmean PM 10 , maximum PM 10 and a significantly greater number of exceedences of thePM 10 24hr mean than the first and third monitoring periods.Table 2.1PM 10 Partisol 2025 Monitoring SummaryMonitoring Period Mean PM 10(µgm -3 )Days where Max PM 10PM 10 24hr (µgm -3 )Mean >50µgm -3Min PM 10(µgm -3 )May-Aug 2004 31.4 7 57.6 11.3Feb-May 2005 33.9 17 80.6 11.0Apr-Jul 2007 32.0 6 69.8 12.3Total 32.4 30 80.6 11.0To further assess the results, the period means were annualised based on the measuredresults from the two nearest long-term AURN background sites with PM 10 monitoring atSouthend-on-Sea and at Thurrock. Annualised Partisol 2025 results are shown in Table2.2. It should be noted that the third monitoring period, conducted in 2007, has beenannualised to represent a 2006 mean as a complete year’s monitoring data is required. Atthe time of writing (September 2007), the 2007 PM 10 monitoring results are not available.To derive the number of exceedences expected from these predicted annual means, theequation below provided in the Technical Guidance LAQM.TG (03) has been used.Number of exceedences of 50µg/m 3 daily mean =-18.5 + 0.00145 x (annual mean PM 10 ) 3 + (206/annual mean PM 10 )Table 2.2Annualised PM 10 Monitored ResultsMonitoringPeriodMonitoringPeriod MeanPM 10 (µgm -3 )AnnualisationFactorAnnualisedMean PM 10(µgm -3 )YearDaysExceedence ofPM 10 24hr MeanMay-Aug 2004 31.4 1.04 32.7 2004 39*Feb-May 2005 33.9 1.03 34.9 2005 49*Apr-Jul 2007 32.0 1.33 42.6 2006 98**Calculated using equation defined in Defra guidance LAQM TG(03) as discussed above.Bureau Veritas Air Quality 9


Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQThe annualised results suggest that the number of exceedences of the PM 10 24 hour meanis greater than the 35 exceedences permitted by the objective in 2004, 2005 and 2006.The 2006 annualised mean PM 10 concentration (based on the 2007 monitoring results) isalso predicted to exceed the annual mean PM 10 objective. However, this calculated resultis significantly influenced by the comparison of background PM 10 levels measured in 2006with the 2007 period monitoring results, which are atypically low for the time of year (April -July) due to abnormally wet weather. Nevertheless, considering the measured periodmean of 32µg/m 3 , if applying the LAQM.TG (03) equation, as shown above, the predictednumber of exceedences over a year would be over the permitted 35.To assess the likely contribution of local fugitive sources from the industrial estate to themeasured exceedences, consideration has been made of the meteorological data (seewind rose figures below) and comparisons with monitoring data from the two nearestAURN background sites over the same period.Of the twenty four measured exceedence days in the 2004 – 2005 monitoring periods,eight days (02/08/04, 03/08/04, 08/02/05, 17/02/05, 18/03/05, 28/03/05, 02/04/05 and23/04/05) could be attributed to elevated regional PM 10 sources, as the same peaks can beseen at the AURN background sites. On these days, the predominant wind direction wasdirectly from the south (or south-south-west or south-south east). On days with southwesterly, westerly or north-westerly prevailing wind directions, such as 28/06/04, 30/07/04,10/03/05, 14/03/05 and 17/03/05, the concentrations measured are much more likely tohave a substantial contribution from the local emissions sources. Other exceedences daysare likely to have both a regional influence, as suggested by AURN background site PM 10concentrations being significantly above the period mean concentration, and a localinfluence, which compounds the PM 10 elevated levels.In 2007, the six exceedences days were: 25 th April, 29 th April, 8 th May, 12 th June, 13 th Juneand 27 th June. These days similarly have elevated concentrations above period meanconcentrations at the AURN sites, with the exception of the 8 th May and 27 th June at theSouthend-on-Sea site. This suggests that exceedences days are likely to have both aregional influence and a local influence, which compounds the PM 10 elevated levels. Onthe 8 th May and 27 th June, the wind direction was south westerly and are therefore likely tohave a substantial contribution from the local emissions sources. This is particularly seenin the case of the 8 th May result, where the maximum (period) daily mean of 70µg/m 3 wasmonitored.Bureau Veritas Air Quality 10

Rochford District CouncilLAQM Detailed AssessmentReport Ref: ADIX0516/BV/AQ3 Conclusions and RecommendationsThe annualised Partisol 2025 PM 10 results from the three (three month) monitoringprogrammes at a residential receptor location in close proximity to the Rawreth IndustrialEstate have indicated that there is a risk that exceedences of the 24-hour mean Objectivemay occur. There are predicted to be greater than 35 exceedences of 50µg/m 3 over theyear, which can be largely attributed to local fugitive emissions sources. Monitoring hasbeen undertaken over both the summer and winter months to establish PM 10 levels inrepresentative meteorological conditions. The most recent monitoring undertaken in April –July 2007, showed 6 exceedences of the 24-hour mean target level for the 3 month period.Although proportionally this appears to be below the permitted 35 exceedences for theyear, when annualised (i.e. taking into account meteorological influences) the exceedencesare calculated to be above this permitted number of exceedences.It is recommended that Rochford District Council consider declaring an Air QualityManagement Area (AQMA) on the basis of the potential exceedences in the Rawrethassessment area as highlighted in this assessment where exposure criteria are fulfilled. It isalso recommended that the Council consider installing a permanent PM 10 monitoring stationin the vicinity of the Rawreth Industrial Estate to enable continued assessment ofcompliance with the 24-hour mean Objective.Bureau Veritas Air Quality 17
