Executive Summary

The UK Government published its strategic policy framework for air quality management in 1995 establishing national strategies and policies on air quality which culminated in the Environment Act 1995. The Air Quality Strategy provides a framework for air quality control through air quality management and air quality standards. These and other air quality standards and their objectives have been enacted through the Air Quality Regulations 2000 and (Amendment) Regulations 2002. The Environment Act 1995 requires local authorities to undertake an air quality review. In areas where air quality objectives are not anticipated to be met, local authorities are required to establish Air Quality Management Areas (AQMA) to improve air quality. Forest Heath District Council completed the first round of its review and assessment of air quality in 2001. Since then further reviews of air quality have been completed to ensure compliance with the air quality objectives. This Air Quality Update and Screening Assessment summarises the results of air quality monitoring across the district during the 2014 calendar year, which has focused on nitrogen dioxide. The monitoring confirms that the general trend in the district is that levels of nitrogen dioxide are generally dropping below the national objective over time. Only one slight exceedence of the national objective for nitrogen dioxide was reported in Forest Heath, which was in Newmarket within the AQMA by the taxi rank on the High Street, but monitoring indicates that the levels of nitrogen dioxide within the AQMA are falling. FHDC continues to work on the Air Quality Action Plan focusing on the improvement of the air quality in Newmarket and works closely with the Transport & Highways Delivery Group of the Newmarket Vision Steering Group to improve traffic flow through the town and ultimately the air quality. Suffolk County Council, FHDC, the Jockey Club and other agencies are all represented on the group. Levels in Brandon through the town along London Road and the High Street continued to be slightly elevated, which can be attributed to congestion as a result of the frequent closure of the level crossing on the High Street/Mundford Road and higher than normal traffic levels through the town while construction on the major project on the A11 to dual it from the Fiveways Roundabout in Barton Mills to Thetford continued. This was completed in December 2014, and the traffic is now signposted to avoid travelling through Brandon, with the expectation that the air quality in the town will significantly improve. Detailed monitoring throughout 2015 will continue in order to assess whether any further action is required. Consequently, there is currently no requirement to move to a Detailed Assessment for any area in the district, with regards to nitrogen dioxide, and the expectation is that the continuing work on the AQAP in Newmarket and the diversion of the traffic from Brandon will see further reductions of the levels of nitrogen dioxide. Additionally, there have been no material changes or developments that put the Government’s objectives for all seven prescribed pollutants at risk of being exceeded, which, in conclusion does not require the undertaking of a Detailed Assessment for any of the other prescribed pollutants.

1 Introduction

1.1 Description of Local Authority Area

Forest Heath District Council (FHDC), as illustrated in Figure 1.1 below, lies within the county of Suffolk, bordered by four local authorities; the Borough Council of Kings Lynn & West Norfolk, Breckland District Council, East Cambridgeshire District Council and St Edmundsbury Borough Council. FHDC covers 37,398 hectares and in 2013, the population of the district was 63,300 (National Online Manpower Information System), of which approximately 12,000 are US personnel and their dependents stationed at RAF Lakenheath and RAF Mildenhall. The towns of Newmarket, Mildenhall and Brandon and the airbases at Mildenhall and Lakenheath are situated within FHDC. Also, the district is crossed by the A11 and A14 trunk roads.

1.2 Purpose of Report

This report fulfils the requirements of the Local Air Quality Management 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.

The objective of this Updating and Screening Assessment is to identify any matters that have changed which may lead to risk of an air quality objective being exceeded. A checklist approach and screening tools are used to identify significant new sources or changes and whether there is a need for a Detailed Assessment. The USA report should provide an update of any outstanding information requested previously in Review and Assessment reports.

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 g/m3 (milligrammes per cubic metre, mg/m3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable).

1.4 Summary of Previous Review and Assessments

FHDC has reported on all previous rounds of review and assessment in accordance with the guidance from LAQM TG (03) & (09). Table 1.2 lists the reports previously produced and their outcomes: Table 1.2: Previous LAQM Reports:

YEAR

REPORT OUTCOME

2006 USA Accepted by Defra – no further action

2007 Progress Report DA required for NO2 on the High Street and Old Station Road, Newmarket

2008 Progress Report Accepted by Defra – no further action

2009 USA Accepted by Defra – no further action

2010 Progress Report No comment from Defra

2011 Progress Report Accepted by Defra after identifying the need for a DA in Brandon

2012 USA Accepted by Defra

2013 Progress Report Accepted by Defra

2014 Progress Report Accepted by Defra

The results from the 2008 PR identified several areas in Newmarket where the annual mean air quality objective for N02 (40µ/m³ annual mean) had not been met and therefore there was a strong possibility that FHDC would have to declare an AQMA. A Detailed Assessment (DA) was undertaken in Newmarket by TRL Ltd and the findings reported to the Department of Environment, Food and Rural Affairs (Defra). Following the reporting of the DA, Defra requested and received further air quality information, which then led to the confirmation that FHDC should declare an AQMA by April 2009 with regards to exceedences of the objective concentration for NO2. The AQMA was to include areas of Newmarket High Street, Old Station Road and the Clock Tower gyratory. There are residential properties within these areas and it will be the primary consideration to improve air quality for these residents and visitors.

Estimation of annual mean concentration from short-term monitoring data for S25 (in brackets above) was calculated on a three month period mean between Jan – Mar in accordance with LAQM.TG(09)

Only one slight exceedence of the national objective for nitrogen dioxide was reported in Forest Heath, which was in Newmarket within the AQMA by the taxi rank on the High Street, but monitoring indicates that the levels of nitrogen dioxide within the AQMA are generally falling. Levels in Brandon through the town along London Road and the High Street continued to be slightly elevated, which can be attributed to congestion as a result of the frequent closure of the level crossing on the High Street/Mundford Road and higher than normal traffic levels through the town while construction on the major project on the A11 to dual it from the Fiveways Roundabout in Barton Mills to Thetford continued. This was completed in December 2014, and the traffic is now signposted to avoid travelling through Brandon, with the expectation that the air quality in the town will significantly improve. Detailed monitoring throughout 2015 will continue in order to assess whether any further action is required.


LAQM USA 2015 15

Figure 2.1: Trends in Annual Mean Nitrogen Dioxide Concentrations measured

at Diffusion Tube Monitoring Sites

Levels within Mildenhall continue to remain relatively stable, with only a slight

increase at the locations on the High Street and Field Road, which are two of the

busiest roads in the town. However, levels are well below the natiional threshold for

nitrogen dioxide, so no further action is required at this time.


LAQM USA 2015 16

This monitoring location is within the close proximity of one of the main gates to RAF

Mildenhall, opposite a substantial residential estate, but as the levels continue to

decrease, no further action is required.


LAQM USA 2015 17

Levels remain relatively stable, well below the threshold, so no further action is

required.


LAQM USA 2015 18

Levels along the main throughfare of the town continued to remain comparatively

high whilst traffic avoided the construction of the dual carriageway on the A11 from

the Fiveways Roundabout to Thetford by travelling through Brandon and the frequent

closure of the level crossing on the High Street/Mundford Road due to faults

attributed to a new system implemented by Network Rail and the actual number of

trains travelling through Brandon on a daily basis. . It is anticipated that the

monitoring from 2015 will show a significant decrease.

required.


LAQM USA 2015 21

Levels within Newmarket are generally falling, although there was another slight

exceedence by the taxi rank (S32) on the High Street within the AQMA. Thorough

monitoring will continue and training is being offered to the taxi drivers in an attempt

to improve their environmental awarness.

FHDC also continues to work on the Air Quality Action Plan focusing on the

improvement of the air quality in Newmarket and works closely with the Transport &

Highways Delivery Group of the Newmarket Vision Steering Group to improve traffic

flow through the town and ultimately the air quality. Suffolk County Council, FHDC,

the Jockey Club and other agencies are all represented on the group.


LAQM USA 2015 22

Levels remain relatively stable, well below the threshold, so no further action is required.


LAQM USA 2015 23

2.2.2 Other pollutants monitored

Forest Heath D.C. does not monitor for any other pollutant.

2.2.3 Summary of Compliance with AQS Objectives

Forest Heath D.C. has examined the results from monitoring in the district.

Concentrations within the AQMA still slightly exceed the objective for nitrogen dioxide

at Newmarket and the AQMA should remain.

Concentrations outside of the AQMA are all below the objectives at relevant

locations, therefore there is no need to proceed to a Detailed Assessment.


LAQM USA 2015 24

3 Road Traffic Sources

3.1 Narrow Congested Streets with Residential Properties Close to the Kerb

Forest Heath D.C. confirms that there are no new/newly identified congested streets with a flow above 5,000 vehicles per day and residential properties close to the kerb, that have not been adequately considered in previous rounds of Review and Assessment.

3.2 Busy Streets Where People May Spend 1-hour or More Close to Traffic

Busy streets (as defined in Table 5.1 of the Technical Guidance LAQM TG(09)) where people may spend one hour or more close to traffic were considered during earlier rounds of the review and assessment process. No relevant exposure was found at any of the locations considered. Since the last assessment no new locations have been found close to streets (within 5 meters), with more than 10,000 vehicles per day, where individuals are likely to exposed for more than one hour.

Forest Heath D.C. confirms that there are no new/newly identified busy streets where people may spend 1 hour or more close to traffic.

3.3 Roads with a High Flow of Buses and/or HGVs.

Roads with a high flow of buses and Heavy Goods Vehicles (as defined in Table 5.1 of the Technical Guidance LAQM TG(09)) were considered during earlier rounds of the review and assessment process. No relevant exposure was found at any of the locations considered. Consideration has again been given to roads where the proportion of buses and HGVs is likely to be in excess of 20%. No roads have been identified that meet this criterion.

Forest Heath D.C. confirms that there are no new/newly identified roads with high flows of buses/HDVs.


LAQM USA 2015 25

3.4 Junctions

Forest Heath D.C. confirms that there are no new/newly identified busy junctions/busy roads.

3.5 New Roads Constructed or Proposed Since the Last Round of Review and Assessment

Prior to re-rerouting and dualling of the A11, exceedences of the air quality objective for nitrogen dioxide were previously measured in the village of Elveden. However, the realignment of the road now avoids the village and any relevant receptors. Therefore, it is anticipated that levels should now be below the air quality objective, which will be substantiated by monitoring in the village throughout 2015 and reported upon in the Progress Report for 2016.

Forest Heath D.C. has assessed the new road (dualled A11 opened in December 2014) meeting the criteria in Section A.5 of Box 5.3 in TG(09), and concluded that it will not be necessary to proceed to a Detailed Assessment.

3.6 Roads with Significantly Changed Traffic Flows

Forest heath D.C. confirms that there are no new/newly identified roads with significantly changed traffic flows.

3.7 Bus and Coach Stations

Forest Heath D.C. confirms that there are no relevant bus stations in the Local Authority area.


LAQM USA 2015 26

4 Other Transport Sources

4.1 Airports

Forest Heath D.C. confirms that there are no airports in the Local Authority area.

4.2 Railways (Diesel and Steam Trains)

4.2.1 Stationary Trains

Forest Heath D.C. confirms that there are no locations where diesel or steam trains are regularly stationary for periods of 15 minutes or more, with potential for relevant exposure within 15m.

4.2.2 Moving Trains

Rail lines with a heavy traffic of diesel passenger trains as described in Table 5.1 of the Technical Guidance LAQM. TG(09) do not pass through the Council’s area.

Forest Heath D.C. confirms that there are no locations with a large number of movements of diesel locomotives, and potential long-term relevant exposure within 30m.

4.3 Ports (Shipping)

Forest Heath D.C. confirms that there are no ports or shipping that meet the specified criteria within the Local Authority area.


LAQM USA 2015 27

5 Industrial Sources

5.1 Industrial Installations

5.1.1 New or Proposed Installations for which an Air Quality Assessment has been Carried Out

Forest Heath D.C. confirms that there are no new or proposed industrial installations for which planning approval has been granted within its area or nearby in a neighbouring authority.

5.1.2 Existing Installations where Emissions have Increased Substantially or New Relevant Exposure has been Introduced

Forest Heath D.C. confirms that there are no industrial installations with substantially increased emissions or new relevant exposure in their vicinity within its area or nearby in a neighbouring authority.

5.1.3 New or Significantly Changed Installations with No Previous Air Quality Assessment

Forest Heath D.C. confirms that there are no new or proposed industrial installations for which planning approval has been granted within its area or nearby in a neighbouring authority.

5.2 Major Fuel (Petrol) Storage Depots

There are no major fuel (petrol) storage depots within the Forest Heath area.

5.3 Petrol Stations

Forest Heath confirms that there are no petrol stations meeting the specified criteria in the technical guidance LAQM. TG(09).


LAQM USA 2015 28

5.4 Poultry Farms

Section 6.9 of the Environmental Permitting (England and Wales) Regulations 2007 requires poultry farms with 40,000 places for poultry to obtain a permit from The Environment Agency to operate. There is one poultry farm that is permitted for this activity by the Environment Agency in Forest Heath. The poultry units at the farm are mechanically ventilated but the number of birds does not exceed 400,000, and do not, therefore, meet the specified criteria.

Forest Heath D.C. confirms that there are no poultry farms meeting the specified criteria.


LAQM USA 2015 29

6 Commercial and Domestic Sources

6.1 Biomass Combustion – Individual Installations

8 Conclusions and Proposed Actions

8.1 Conclusions from New Monitoring Data

A slight exceedence of the annual mean for nitrogen dioxide in 2014, was found at the following location:

Newmarket within the boundary of the AQMA.

However, the monitoring data for 2014 confirms that the general trend in the district is that levels of nitrogen dioxide are generally dropping below the national objective over time.

8.2 Conclusions from Assessment of Sources

There are currently no new approved local developments that will require more detailed consideration. Work to implement the Air Quality Action Plan for Newmarket will continue, in conjunction with the objectives of the revised Local Air Quality Strategy. The Council aims to manage local air quality in order to discharge its statutory responsibilities arising from the National Air Quality Strategy and in doing so, improving local air quality to ensure air pollution remains below prescribed levels, thus maintaining the health and well-being of our residents. Local air quality is also dealt with through the planning system, where it may be a material consideration that requires an assessment to be made on the impact of the projected increase in road transport that will have on future air quality.

8.3 Proposed Actions

The monitoring for nitrogen dioxide throughout Forest Heath in 2014 has not identified the need to proceed to a Detailed Assessment, or any additional monitoring. The 2016 Progress Report will be submitted in due course.

Appendix A: QA/QC Data

Diffusion Tube Bias Adjustment Factors

Concentrations of NO2 are measured across FHDC using diffusion tubes. The tubes

are currently prepared and analysed by Environmental Scientifics Group using the

50% TEA in acetone method.

The results of the analysis of the diffusion tubes for 2014 were bias adjusted using

version 03/15 of the spreadsheet supplied by the Air Quality Review and Assessment

Helpdesk The bias adjustment factor was taken to be the average from the co-

location studies and a bias adjustment factor of 0.81 was calculated for the FHDC

2014 diffusion tube data.
