Executive Summary

The Environment Act 1995, Part IV places a statutory obligation on all local authorities to review and assess the air quality within their area against Air Quality Objectives. Progress Reports have been introduced into the Local Air Quality Management (LAQM) system following a detailed evaluation of the review and assessment process. Updating and Screening Assessment (USA) reports are prepared in the years when local authorities are not carrying out their statutory annual progress reports or carrying out Detailed Assessments. This practice ensures that air quality is continually being assessed and reviewed. Derbyshire Dales is primarily a rural area with a total population in the region of 70,000. The total area of the District is approximately 780 square kilometres and half of the District is within the Peak District National Park. The April 2011 Progress Report concluded that, with the exception of the single AQMA, there would be no exceedence of the air quality objectives in Derbyshire Dales. The report discussed ongoing monitoring in relation to the single AQMA designated in February 2010. The April 2012 USA is an update of work and monitoring results that have been collated over the previous 12 months and concludes that there is no need to progress to a Detailed Assessment for any pollutants. It is proposed to revoke the single AQMA and this will be undertaken during 2012.

1 Introduction

1.1 Description of Local Authority Area

The area administered by Derbyshire Dales District Council is primarily rural in character comprising 113 parishes with a total population in the region of 70,000. The total area of the District is approximately 780 square kilometres and at its extremes is 58 km long and 27 km wide. Half of the District is within the Peak District National Park. The District is situated within the East Midlands and is bounded by the local councils of High Peak Borough, Sheffield City, North East Derbyshire District, Amber Valley Borough, South Derbyshire District, East Staffordshire District and Staffordshire Moorlands District. There is a strong tradition of agricultural and a long history of mineral extraction. Vein minerals are still extracted today, primarily to provide fluorspar for use in the chemical and steel industries and limestone is extensively quarried for aggregate. Where the purity of calcium carbonate is high, fine powders are produced for use in industries such as glass making, foodstuffs and pharmaceuticals. Light industry has developed at a number of sites, notably the Airfield Industrial Estate in Ashbourne. There are currently 63 installations regulated by the District Council under the Environmental Permitting Regulations 2010 and 21 installations or waste activities regulated by the Environment Agency. The road network in the District is extensive with the A623, A6, A52 and A50 acting as important links between the North West and the East Midlands, although there are no motorways. The Hope Valley railway line passes through the north of the District and local trains serve Grindleford and Hathersage, and Matlock is the terminus of a branch line from Derby. Peak Rail is a voluntary organisation that operates trains on a five kilometre section of track between Matlock and Rowsley South using steam and diesel traction. The Ecclesbourne Valley Railway is operating part of the branch line between Wirksworth and Duffield.

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 USA 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. 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).

1.4 Summary of Previous Review and Assessments

Until 2009, no previous rounds of Review and Assessment have identified any likely exceedences of the UK Air Quality Objectives in Derbyshire Dales. However, direct progression to a Detailed Assessment was made in 2009 in response to monitoring undertaken by the Environment Agency from October 2008 to May 2009. This resulted in the declaration of an AQMA in February 2010, as discussed in the 2010 and 2011 Progress Reports. The AQMA was declared for an exceedance of the PM10 24-h (midnight-midnight) mean objective and covers a single residential dwelling adjacent to Stoneleigh Cottage Poultry Farm, Cubley. The area of the AQMA is presented in Figure 1 and the Detailed Assessment is available to download from the District Council website at: http://www.derbyshiredales.gov.uk/environment-and-waste/pollution/air-pollution/air-quality-management-areas/cubley The following reports have been produced in previous years and the more recent ones are available to download from the District Council website at: http://www.derbyshiredales.gov.uk/environment-and-waste/pollution/air-pollution/air-quality-reports-and-monitoring-information

2 New Monitoring Data

2.1 Summary of Monitoring Undertaken

2.1.1 Automatic Monitoring Sites

There are no automatic monitoring sites in Derbyshire Dales.

2.1.2 Non-Automatic Monitoring Sites

During 2011 nitrogen dioxide concentrations have been measured at 13 locations (Table 2) throughout the District by diffusion tube. Monitoring at these locations commenced in December 2007. Location maps are presented in Appendix A. The number of diffusion tubes deployed was reduced from 5 April 2011 for financial reasons. Only the data from tubes that were deployed for a full twelve months during 2011 is presented. Sites were identified based on guidance contained in the Diffusion Tube Network Instruction Manual (DEFRA 2003; version 1.5) and Diffusion Tubes for Ambient NO2

Monitoring: Practical Guidance for Laboratories and Users (AEA 2008). Site location took into account roads and junctions with high traffic flows, as detailed in the 2003 and 2006 USA reports, and their proximity to receptors. The majority of tubes were hung on building facades and all tubes were hung as close as physically possible to the nearest relevant exposure. A monitoring site was located for rural background in the village of Eyam (Site Ref. 17).

Tubes are provided and analysed by Gradko International Ltd and are prepared using 20% triethanolamine (TEA) in water. Results for each tube have been corrected for bias using a factor of 0.89 for 2011 as detailed on the National Diffusion Tube Bias Adjustment Factor Spreadsheet (03/12) accessed on 16 April 2012, and are presented in Table 3. http://laqm.defra.gov.uk/bias-adjustment-factors/national-bias.html. A travel blank was analysed on all occasions. Gradko actively participated in, and provided input to, the Working Group on Harmonisation of Diffusion Tubes (AEA 2008). Gradko also demonstrated “Good” performance in the WASP scheme for the analysis of nitrogen dioxide diffusion tubes in Rounds 104 -108 (January 2009 – January 2010) and rounds 105 – 109 (April 2009 – April 2010).

No co-location studies have taken place in Derbyshire Dales

2.2 Comparison of Monitoring Results with AQ Objectives

Monitoring has been undertaken in relation to Air Quality Objectives for nitrogen dioxide at 13 locations, as discussed in Section 2.1.2, and for lead at a single location close to H.J.Enthoven & Sons which is the largest single site producer of recycled lead in Europe.

2.2.1 Nitrogen Dioxide

Diffusion Tube Monitoring Data

During 2011 nitrogen dioxide concentrations were measured at 13 locations (Table 2) throughout the District by diffusion tube. No tubes were located within an AQMA and all locations are considered to be representative of public exposure. Results from previous deployments are presented in the Progress Reports for 2011 and 2010. All tubes were deployed singly and each deployment was for a period of 4 weeks. Results are presented for 12 deployments between 14 December 2010 and 15 November 2011. Results for each tube have been corrected for bias using a factor of 0.89 for 2011 as detailed on the National Diffusion Tube Bias Adjustment Factor Spreadsheet (03/12) accessed on 16 April 2012, and are presented in Table 3. This bias adjustment factor is the result of 26 co-location studies around England. http://laqm.defra.gov.uk/bias-adjustment-factors/national-bias.html Data capture at all sites was above 80%. Where data capture was less than 100% this was due to stolen tubes on two of the twelve deployments.

There are no measured exceedences of the 40 µg/m3 annual mean objective at any of the monitoring locations (Table 3 below) and the highest reported bias adjusted mean

concentration is 33.70 µg/m3 at Site Ref. 11 (St John Street, Ashbourne).

2.2.3 Sulphur Dioxide

Sulphur dioxide is not routinely monitored in Derbyshire Dales.

2.2.4 Benzene

Benzene is not routinely monitored in Derbyshire Dales.

2.2.5 Other pollutants monitored

Airborne concentrations of lead from the smelter operated by H.J.Enthoven & Sons have been monitored on an approximately weekly basis by Derbyshire Dales District Council at different sites in South Darley since 1986. H.J.Enthoven & Sons is an A1 process regulated by the Environment Agency under the Environmental Permitting Regulations 2010 and is the largest single site producer of recycled lead in Europe. The current site at Warren Carr (NGR 426096, 362576) has been monitored since 1991 and allows trends to be plotted at the site of a residential property located close to the site. An “M” Type sampler is used to draw a measured volume of air (m3) through a Millipore Aerosol filter paper. Analysis of the filters is undertaken by Scientific Analysis Laboratories Ltd for lead content using inductively-coupled plasma optical emission spectroscopy (ICP-

OES). The current ICP-OES Limit of Detection is 1 µg. Where the total lead content on the

filter is reported as below the Limit of Detection a value of 0.5 µg has been used in the calculations. During 2011 there were no reports of lead at or below the Limit of Detection.

The lead content of the filter (µg) is then expressed per m3 of air filtered during the filter

exposure period (µg/m3). The lead in air concentration is calculated and the annual average is plotted on a graph allowing a clear comparison with the Air Quality Objective. The annual mean results for the years 1991 to 2011 are presented in Figure 2 below. The 2011 annual mean result at the Warren Carr monitoring site is marginally above the

Air Quality Objective (0.25 µg/m3), at 0.32 µg/m3. This annual average is however below

the Limit Value of 0.5 µg/m3 contained in the Air Quality Standards Regulations 2010 for the protection of human health. The 2010 Regulations contain the provisions of Directive 2008/50/EC. A graph of the weekly results for 2011 is presented in Figure 3. Data supplied by H.J.Enthoven & Sons, as the mean of three air samplers situated at suitable locations close to the installation, is presented in Figure 4. At the current time the concentration of lead measured during 2010 is not considered to warrant a Detailed Assessment, nor is it considered to be of significance for human health. Concentrations will continue to be monitored during 2012.

4 Other Transport Sources

4.1 Airports

Derbyshire Dales District Council confirms that there are no airports in the Local Authority area.

4.2 Railways (Diesel and Steam Trains)

There are four train lines within Derbyshire Dales. The Derwent Valley Line operates hourly from Matlock to Derby, calling at Matlock, Matlock Bath and Cromford Stations within Derbyshire Dales. The Hope Valley railway line passes through the north of the District and local trains serve Grindleford and Hathersage. The Ecclesbourne Valley Railway is community owned and is operating on part of the branch line between Wirksworth and Duffield, 2.6 km of which runs through Derbyshire Dales. The Ecclesbourne Valley Railway primarily operates at weekends, with four return journeys per day using either diesel or steam trains. Peak Rail operate a short stretch of railway between Matlock and Rowsley South, covering approximately 5 km. The line forms part of the old Midland Railway’s line between Manchester Central and London St Pancras which was closed in 1968. On 2 July 2011 Peak Rail extended its operations approximately 700 m from Matlock Riverside Station to the main Matlock Station. Peak Rail operates throughout the year, primarily at weekends, and all services are currently top and tailed with steam and diesel locomotives. Five return journeys from Rowsley South to Matlock are made on the days the railway operates

4.2.1 Stationary Trains

Derbyshire Dales District Council 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

Derbyshire Dales District Council confirms that there are no locations with a large number of movements of diesel locomotives, and potential long-term relevant exposure within 30m.

5 Industrial Sources

5.1 Industrial Installations

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

Derbyshire Dales District Council 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

Derbyshire Dales District Council 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

Derbyshire Dales District Council 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 Local Authority area.

5.3 Petrol Stations

Traffic count data (two–way) was obtained from the Highways Authority at Derbyshire County Council in March 2012 for the years 2009, 2010 and 2011. Traffic was monitored at 20 locations in Derbyshire Dales over the three years. Based on the supplied data, and data collected for the 2006 USA, there is a single road where there is more than 30,000 vehicles per day. This is the A50 in Sudbury. Twelve hour traffic count data recorded in May 2010 reported 41,518 vehicles. Using either a 20 or a 25% extrapolation factor to predict 24-h vehicles movements, it is predicted maximum vehicles per day will be between 49,822 and 51,898. Based on the 12-


LAQM USA 2012 23

h collected data, this is an approximate 8% increase in traffic compared to monitoring undertaken in 2008. There are no petrol stations in the vicinity and therefore the AQO for benzene is not considered to be at risk of being exceeded.

Derbyshire Dales District Council confirms that there are no petrol stations meeting the specified criteria.

5.4 Poultry Farms

There are currently 9 poultry farms with places for more than 40,000 broilers permitted by the Environment Agency under the Environmental Permitting Regulations 2010. One poultry farm has closed since the 2009 USA. There are no turkey units within the District. The poultry farms were discussed in the 2008 Progress Report and 2009 USA. The installation with the greatest number of broilers is 215,000 at Hollington Poultry Farm which is mechanically ventilated. The second highest number of broilers is 160,000 at Hollywood Poultry Farm. Consequently there are no poultry farms that meet the criteria specified in TG(09) (Defra 2009). One poultry farm, Stoneleigh Cottage Farm, Cubley, currently forms part of an AQMA due to emission of PM10 despite not meeting the specified criteria. This is discussed in detail in the 2011 Progress Report. A further assessment was undertaken by the Environment Agency between 30 November 2010 and 1 January 2011 (63 days) and between 2 June 2011 and 12 August 2011 (72 days), covering two seasons. The results of this monitoring have not identified any exceedance of the 24-h, or annual mean, PM10 Air Quality Objective. A proposal to revoke the AQMA was submitted to Defra in December 2011, who confirmed the proposal is supported. At the start of a six week consultation period on 12 December 2011 all residents in Cubley Village, along with a range of statutory consultees, were notified of the proposed revocation. The full report is available on the District Council website at http://www.derbyshiredales.gov.uk/environment-and-waste/pollution/air-pollution/air-quality-management-areas/cubley/proposed-revocation A report recommending revocation of the AQMA will be presented at the District Council Community and Environment Committee on 19 April 2012. If the proposal is supported, an Order will be signed by the authorised signatory revoking the AQMA. A copy of the Order will be submitted to Defra. Derbyshire Dales District Council confirms that there are no poultry farms meeting the specified criteria.

6 Commercial and Domestic Sources

6.1 Biomass Combustion – Individual Installations

Since the 2009 USA, biomass boilers between 50 KW and 200 MW have been installed at three locations, and all three are operated using wood chip: Chatsworth Estate Office, Edensor KOB Rotary Combustion Boiler; 199 kW Chatsworth House, Edensor Herz Biomatic 500; 500 kW Hallcroft Farm, Hollington GlenFarrow GF400; 400 kW

Derbyshire Dales District Council has assessed the biomass combustion plant, and concluded that it will not be necessary to proceed to a Detailed Assessment.

6.2 Biomass Combustion – Combined Impacts

Derbyshire Dales District Council has assessed the biomass combustion plant, and concluded that it will not be necessary to proceed to a Detailed Assessment.

6.3 Domestic Solid-Fuel Burning

Domestic solid-fuel burning was discussed in the 2009 USA and the 2010 Progress Report. The estimated number of domestic properties undertaking biomass burning, combined with the current known service sector biomass combustion appliances, suggests the impacts are likely to be low at the current time. This situation will be kept under review.

Derbyshire Dales District Council confirms that there are no areas of significant domestic fuel use in the Local Authority area.

8 Conclusions and Proposed Actions

8.1 Conclusions from New Monitoring Data

Lead monitoring at Warren Carr has identified a slight increase in lead concentrations compared to previous years, however it is not considered this poses a risk to human health. There will be no progression to a Detailed Assessment. The Further Assessment in respect of the AQMA has led to the conclusion there is no longer an exceedance of the 24-h PM10 air quality objective within the AQMA. It is proposed to revoke the AQMA in April 2012, as discussed in section 5.4. No other new monitoring data has identified any potential or actual exceedences at relevant locations.

8.2 Conclusions from Assessment of Sources

An assessment of sources has not identified any significantly changed sources or any potential exceedences outside of the single AQMA in Derbyshire Dales.

8.3 Proposed Actions

This assessment has not identified the need to proceed to a Detailed Assessment for any pollutant. No additional monitoring has been identified as being required. Existing monitoring of nitrogen dioxide and lead will continue during 2012. Provided the proposal to revoke the Cubley AQMA is supported at the Community and Environment Committee on 19 April, an Order to revoke the AQMA will be signed and submitted to Defra. This will be publicised on the District Council website. A 2013 Progress Report will be prepared in April 2013.
