Executive Summary

This report presents monitoring data for 2012 and other assessments of potential pollutants and new sources within the Borough. The main pollutant of concern in Calderdale, and the only one for which monitoring is reported here, is nitrogen dioxide, essentially traffic-related. The monitoring results show that although the nitrogen dioxide annual mean objective is still being breached in all six AQMAs there is scope for reducing the size of some of the areas, particularly No. 1 Salterhebble, No. 4 Luddendenfoot and No. 5 Stump Cross. The Council is drafting a report which will form the basis for consultation on changes to these AQMAs. Annual mean concentrations above the annual mean objective have been measured at sites outside existing AQMAs and the Council is preparing to declare an AQMA at Hipperholme, while continuing to gather sufficient data to produce a Detailed Assessment for Ainley Top and Clough Lane, Rastrick. The data for 2012 indicates that average concentrations of nitrogen dioxide fell compared to those recorded in 2011, but it is not clear that this is a long term trend. Some further information is being sought from the operator about newly installed biomass combustion plant.

1 Introduction

1.1 Description of Local Authority Area

Calderdale MBC is one of the five local authorities making up the West Yorkshire metropolitan area. Calderdale lies to the west of the area, straddling the Pennines and including urban town centres such as Halifax and Brighouse, and smaller centres at Elland, Sowerby Bridge, Hebden Bridge and Todmorden. The urban centres in the upper Calder Valley are linked by roads lying in valley bottoms, with dwellings very close to the roadside and few alternative routes available to traffic. The M62 motorway skirts the south and east of the Borough and in the event of accidents or carriageway closures traffic may be diverted through Calderdale, particularly along the A58 and A672. Good motorway access has contributed to modern industrial developments at Elland and Brighouse. Although the nature of the industries based in Calderdale has changed quite radically over the years there is still a strong manufacturing and service base.

1.2 Purpose of Progress 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.

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 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).

Romon 1 The annual mean concentration for 2012 at this location is roughly the same as that for 2012. There were no exceedences of the hourly mean objective, as in previous years. Romon 2 The 2012 annual mean is slightly higher than that for 2011. It was observed during the later part of 2012 that calibration with the span gas was subject to large drifts. The problem was reported to the Councils air quality servicing contractor but was not fully resolved until early 2013. The annual data is therefore taken to be indicative. The number of exceedences of the hourly objective has dropped to zero from 34 in 2011. This does not appear to be due to instrument faults. Romon 3 This unit was damaged during the severe floods of 2012 and no data is reported for 2012. Romon 4 The annual mean for 2012 is much lower than that for 2011. There appears to be no fault with the analyser and the reduction must be taken at face value.

** Ten months data available, March to December 2012

Trends in nitrogen dioxide concentrations The results for 2012 show a decrease in comparison with those for 2011 at almost all sites. This is also true of the continuous data and appears to reflect a real reduction across the Borough. Note that the bias correction factor for 2012 is significantly smaller than that for 2011. The raw data is presented in the appendices. A notable exception is at the location of the tube CRH1, where the concentrations are

essentially unchanged, and remain above 60gm-3. This may indicate an exceedence of the hourly objective, but it is not possible to relocate a continuous analyser to verify this. The tube is in an AQMA declared for the annual mean objective. Previously the Council has operated a continuous analyser, Romon 1, at a nearby site (see [PR07]) and the data indicated that the hourly objective was not being breached at that location. In the case of CRH1 there is a more enclosed canyon-like environment, and breaches of the hourly objective cannot be ruled out. The respective locations of the analyser and CRH1 are shown in Figure 2.5 below.

Figure 2.6 takes two sets of diffusion tube results for which a long data set is available and compares the raw and bias corrected trends (e.g. HB1 and HB1_bc). The data for tube HB1 (in the centre of Hebden Bridge) shows an overall increase in annual mean concentrations since 2004, starting below the annual mean objective (when the bias correction factor was found from a collocation study using a mobile monitoring unit to be 0.66) and ending in 2012 well above the objective. Between 2006 and 2011 the raw mean in particular remained quite constant, while the raw data for CRH1 rose steadily until 2011.

No monitoring for benzene has been carried out.

2.2.4 Other Pollutants Monitored

No monitoring for other pollutants has been carried out.

2.2.5 Summary of Compliance with AQS Objectives

Calderdale Council has examined the results from monitoring in the Borough.

Concentrations within the AQMAs still exceed the annual mean objective for nitrogen

dioxide at all the existing AQMAs and the AQMAs should remain. There is scope for

reducing the size of some of the AQMAs and the Council is preparing a report on

these lines.

The Council has measured concentrations of nitrogen dioxide above the annual

mean objective at relevant locations outside of the AQMAs, and is preparing a

Detailed Assessment for Ainley Top and Clough Lane, Rastrick. The Council is

also in the process of declaring an AQMA at Hipperholme.

3 New Local Developments

3.1 Commercial and Domestic Sources

3.1.1 Commercial and other non-domestic sources

A number of schools and academies have installed small biomass boilers. These have all fallen below the chimney height thresholds in the Clean Air Act 1993 and their impact has not been quantified. No other new commercial and non-domestic sources have been identified.

The Council confirms that there are no new or newly identified local developments

not covered in other sections of this report which may have an impact on air quality

within the Local Authority area.

The Council confirms that all the following have been considered:

Road traffic sources

Other transport sources

Industrial sources

Commercial and domestic sources

New developments with fugitive or uncontrolled sources.

4 Planning Applications

The two applications with potential air quality impacts are described below.

4.1 Elland Edge Quarry

Planning permission was granted in 2010 for an extension to a quarry overlooking Elland. The applicant provided a dust action plan considering the potential for dust emissions, particularly nuisance dust, and a range of control measures. Conditions on the planning permission were discharged in 2011. There have in the past been complaints from residents about airborne dust, particularly during crushing campaigns, but monitoring carried out using a TEOM and reported in the Stage 3 report [S3] lead to the conclusion that the quarry was not contributing significantly the mean concentration of PM10. The Council does not propose further monitoring of this site, although complaints about dust emissions will be followed up.

4.2 Hipperholme and Lightcliffe School

Planning consent was granted in 2012 for a new boiler house incorporating three 250kW biomass boilers at this school. The intended fuel is processed wood pellets, which takes the installation outside the provisions of the Environmental Permitting (England and Wales) Regulations 2010. Each boiler has a stack terminating 2.5m above the roof of a 5.5m high building. The stack diameter is estimated to be 0.4m, although full details are not yet available. Using the 2009 Corinair data ([Corinair]) for commercial biomass combustion plant the emission rate for particulate matter (PM10) is expected to be around 150g/GJ for each boiler. For a 250kW plant this equates to 0.038g/s. Using the biomass spreadsheet tool we find the target emission rate for a single stack of the given height to be 0.031g/s, and the estimated emissions are greater than the target emissions. The situation is complicated by the fact that there are three stacks on the same building and that the dispersion may be affected by the large school building upwind of the prevailing wind direction. The Council is seeking further information from the applicant, including a chimney height application with details of the boilers and emission rates. Preliminary modelling using ADMS-Urban 3.1.0 and the Corinair emission factors indicates that the installation will not contribute significantly to the annual mean nitrogen dioxide or PM10 concentrations.

5 Air Quality Planning Policies

Local planning policies relating to air quality were essentially set aside on the introduction of the Local Development Framework. One policy remains: Policy EP 1 Protection of Air Quality Development which might cause air pollution (including that from modes of transport) will only be permitted if:-

i. it would not harm the health and safety of users of the site and surrounding area; and

ii. it would not harm the quality and enjoyment of the environment. Where permission is granted, appropriate conditions and/or planning obligations will be attached to ensure that the air quality is maintained. although paragraph 124 of the National Planning Policy Framework will take precedence when considering planning applications.

6 Local Transport Plans and Strategies

West Yorkshire Transport Plan Partnership, of which the Council is a member, produced LTP1, its Local Transport Plan for 2001 to 2006, and replaced it in 2006 with LTP2, which expired in 2011. The current transport plan, LTP3 has three main objectives covering transport improvements to support and encourage economic growth in West Yorkshire and Leeds City region, move towards a low carbon transport system in the County and enhance the quality of life of people living and working in the County. Congestion and lack of investment in transport are to be addressed through the implementation of the plan.

More information, and the complete set of plans, can be found at http://www.wyltp.com/

7 Climate Change Strategies

Calderdale Council has developed a climate change strategy called Calderdales Energy Future.

7.1 Calderdale's energy future

Calderdale's Energy Future sets out how Calderdale Council and its partners can transform Calderdale into a resilient low carbon economy, leading to a 40% reduction in carbon emissions by 2020 (from a 2005 baseline). It focuses attention on priority actions that will have the biggest carbon reduction impact while protecting Calderdales communities and landscapes. The Council aims to achieve these targets in a way that delivers the maximum social, economic and environmental benefits to the community.

The full strategy document and executive summary are available on the website http://www.calderdale.gov.uk/environment/sustainability/environmental-projects/energy-future.html .

9 Conclusions and Proposed Actions

9.1 Conclusions from New Monitoring Data

The monitoring results show that although the nitrogen dioxide annual mean objective is still being breached in all the AQMAs there is scope for reducing the size of some of the areas, particularly No. 1 Salterhebble, No. 4 Luddendenfoot and No. 5 Stump Cross. The Council is drafting a report which will form the basis for consultation on changes to these AQMAs.

9.2 Conclusions relating to New Local Developments

No new developments have been identified that have been found likely to have an impact on air quality.

9.3 Other Conclusions

No pollutants other than nitrogen dioxide have been monitored, and the Council is not aware of any proposed or active developments that would require such monitoring.

9.4 Proposed Actions

The Council is using its limited monitoring resources to gather evidence to justify further action in areas where an exceedence of the air quality objectives has been observed and where the air quality objectives are being met within an AQMA. AQMAs in which there is evidence supporting reducing the extent of the AQMA are

No. 1 Salterhebble No. 4 Luddendenfoot No. 5 Stump Cross

The Council is preparing a Detailed Assessment covering proposed changes to the extent of these AQMAs. AQMAs in which there is evidence for exceedence of the hourly objective are

No 1 Salterhebble this is to be considered in the Detailed Assessment covering the revision of the AQMA boundary

Areas outside AQMAs where there is evidence for an exceedence of the annual objective for nitrogen dioxide are

Areas around M62 including Ainley Top and Rastrick - The Council is collecting more evidence on the likely extent of the area of exceedence

Hipperholme the Council is consulting on the declaration of an AQMA Biomass combustion plants for which further information is being collected are

Hipperholme and Lightcliffe High School [expected Summer 2013]

jennyshepherdHighlighthas this data been collected?

Calderdale MBC


Next actions The Council proposes to

submit a Detailed Assessment for existing AQMAs and exceedences of the hourly objective in AQMA No.1 Salterhebble in Autumn 2013

complete its consultation on the declaration of AQMA No. 7 Hipperholme by 1st June 2013, and declare the AQMA by 1st September 2013

complete its assessment of the biomass boilers at Hipperholme and Lightcliffe High School when the required information is received and proceed to a Detailed Assessment if required

complete additional monitoring at Ainley Top and Rastrick by 31st December 2013, and submit a detailed assessment in Spring 2014

submit the 2014 Progress Report in April 2014.

Appendices

Appendix A: QA:QC of monitoring Diffusion Tube Bias Adjustment Factors

Discussion of Choice of Factor to Use

The local factor was 0.74, and the overall factor for tubes prepared and analysed by West Yorkshire Analytical Services was 0.79. The latter includes the Councils collocation data and has been adopted by the Council as it is likely to represent the response of the diffusion tubes over a wider range of exposure conditions than the local factor. Both factors appear in Figure A1, which is a screenshot of the latest LAQM spreadsheet.

Figure A1: Factor from LAQM Helpdesk spreadsheet

Short-term to Long-term Data adjustment No short-to-long-term data adjustment has been made in the report.

QA/QC of Automatic Monitoring The Councils automatic monitors are serviced under contract twice yearly by ET Kingfisher Business Park, London Road, Stroud, Gloucestershire GL5 2BY. Routine checks on the units are carried out by Council staff at least once every two weeks, and there is a call-out element to the contract in the event of instrument malfunction.

Romon 1, Brighouse There were no problems with this analyser in 2012. Romon 2, Salterhebble This analyser showed some instability during 2012. This was reported to the contractor (then Casella) but a robust resolution was not obtained until early 2013. The data from this analyser is reported, and seems reasonable, but should be treated with caution.

Calderdale MBC


Romon 3, Hebden Bridge The severe floods of 2012 put this unit out of action for part of the year. Romon 4, Sowerby Bridge There was a brief episode of unreliable data, which was remedied by the contractor.

QA/QC of Diffusion Tube Monitoring

The Council uses diffusion tubes prepared and analysed by West Yorkshire Analytical Services. This laboratory achieved good precision for 2012 in the summary at http://laqm.defra.gov.uk/diffusion-tubes/precision.html. Recent quality control (WASP) assessments have indicated that there may be laboratory systematic bias, based on the results for R116, R117 and R118 (first three quarters of 2012).
