LAQM Progress Report 2014 1 Council

Executive Summary

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 , Scotland, Wales and Northern Ireland 2007 and the relevant Policy and Technical Guidance documents.

The primary pollutant of concern for the District continues to be NO 2 resulting from traffic.

Stroud District Council undertook diffusion tube monitoring at 25 locations in 2013.

The 2013 Progress Report identified two sites that exceeded the annual objective of 40 µg/m 3 and recommended more detailed assessment of these sites.

Dudbridge Hill

This is a triangular area of land containing a number of residential properties. It is surrounded on two sides by roads with moderately heavy traffic flows. Ten NOx tubes are distributed across this area. Following the elevated levels in 2013 and given the inherent inaccuracies of NOx tubes, consideration was given to the installation of continuous automatic NO 2 monitoring. It was not possible to obtain a suitable power supply for such monitoring and assessment of this site continues to be based upon NOx tubes.

NO2 levels for 2013 have fallen from previous years. As a result only one of the ten sites at Dudbridge Hill is marginally above the relevant NO 2 air quality objective. Given this marginal exceedance the additional NOx tubes that were put in place following elevated levels in 2012 shall be kept in place and analysed for the period 2015.

LAQM Progress Report 2014 2 Stroud District Council

Bowbridge

The 2013 Progress Report identified NO 2 levels at the Bowbridge site as marginally exceeding the annual air quality objective. The receptor at this site is a flat above a public house. It is situated next to a traffic light controlled cross roads and bus stop.

Automatic Continuous NO 2 monitoring was installed at the Bowbridge site between December 2013 and October 2014. The results will be reported in the 2015 Updating and Screening Assessment.

The NOx tube monitoring data for the period Jan 2013 – December 2013 indicates that the annual bias adjusted NO 2 levels have fallen from the previous years and are now below the relevant NO 2 air quality objective.

Overall Trend

The annual average levels of NO 2 measured in 2013 are, across the majority of sites, significantly lower than those measured in 2012 and reported in the 2013 progress report.

There are at present no concerns in the other areas monitored.

LAQM Progress Report 2014 5 Stroud District Council 1 Introduction 1.1 Description of Local Authority Area

The Stroud District has an area of 453km2, a population of approximately 108,000 and lies in immediately to the south of Gloucester City, bordering the River Severn on its western edge. The district is divided from the south west to the north east by the M5 motorway. It shares boundaries with Gloucester City Council, Tewkesbury Borough Council, Cotswold District Council, South Council and across the Severn, The Forest Of Dean District Council. It contains 6 distinct market towns – Berkeley, Dursley, Nailsworth, Stonehouse, Stroud and Wotton under Edge. The city of Bristol is located some 15 miles beyond the southern boundary.

It is predominantly a rural area and thus attracts tourists and wealthy migrants, often retirees. Three quarters of its population live in the settlements of the Stroud Valleys and the market towns of Cam, Dursley and Wotton under Edge. It also has an industrial heritage, originally based on wool, which has left a strong engineering and manufacturing legacy albeit with no heavy industry.

The most significant influence on air quality within the district is from local road traffic. There are also a number of ‘prescribed processes’ located within the district. These are industrial processes regulated by the Environment Agency (Part A(1) processes) and by the District Council Part (A(2) and Part B processes). These are listed in Appendices A, B and C. None are considered to be of any major influence on local air quality.

A major restoration scheme of a 6 mile stretch of canal between Stonehouse via Stroud to Brimscombe is under way with associated housing developments and regeneration of adjacent industrial sites.

LAQM Progress Report 2014 8 Stroud District Council 1.2 Purpose of Progress Report

This report fulfils the requirements of the Local Air Quality Management (LAQM) 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 LAQM process.

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 µg/m 3 (milligrammes per cubic metre, mg/m 3 for carbon monoxide) with the number of exceedences in each year that are permitted (where applicable).

2 New Monitoring Data 2.1 Summary of Monitoring Undertaken

2.1.1 Automatic Monitoring Sites

Stroud District Council has investigated the installation of continuous NO 2 monitoring equipment at the two sites identified in the 2013 progress report as exceeding the annual NO2 air quality objective. These sites are Dudbridge Hill and Bowbridge. Continuous monitoring was installed at Bowbridge and continuous data obtained for the period 16/12/13 – 22/10/14. The results of this monitoring will be reported in the 2015 Updated Screening and Assessment report.

A suitable power supply could not be secured for the Dudbrige site which has precluded continuous monitoring from being undertaken at this time. Extra NOx tubes were installed at this site when elevated levels were first noted. These will continue to be used to assess the air quality at this site.

2.1.2 Non-Automatic Monitoring Sites

Stroud District Council undertook NO2 monitoring with diffusion tubes at 25 sites in 2013.

Tubes were prepared using 50 µl of 20% triethanolamine in water and tube preparation and subsequent analysis follow the procedures in the harmonised "Practical Guidance" document (Ref1). All diffusion tubes are stored, handled and exposed in accordance with the relevant guidance. All diffusion tubes have a monthly exposure period.

Stroud District Council does not undertake any co-location studies, so bias adjustment factor for 2013 was obtained from the National Bias Adjustment Factor Spreadsheet. • 2006 – 0.90 for 5 studies • 2007 – 0.77 for 5 studies • 2008 – 0.87 for 4 studies • 2009 – 0.86 for 2 studies • 2010 – 0.85 for 7 studies • 2011 – 0.82 for 10 studies • 2012 – 0.95 for 2 studies • 2013 – 0.90 for 3 studies

4 Local / Regional Air Quality Strategy

The six local authorities of Gloucestershire work actively together to seek air quality improvements, through the Gloucestershire Pollution Group (GPG) which is a sub- committee of the Chief Environmental Health Officers. Future funding mechanisms for the routine requirements of local air quality management, and for the implementation of initiatives, will best be achieved through a collaborative Pollution Group approach. Future proposed revisions of the National Air Quality Strategy, national Air Quality Objectives and the introduction of newly regulated pollutants are best addressed through the work of this group.

The development of a county-wide Air Quality Strategy for Gloucestershire, provides an important framework for maintaining good air quality and improving upon poor air quality over the years ahead. As the pressures of large-scale developments, housing growth and road building increases, so too will the need for maintaining the quality of the environment and the health and well-being of the public and communities now, and in the future.

Community planning and sustainability planning processes underway within the local authorities and the county will need to take account of local air quality for the benefit of communities now, and in future across Gloucestershire. Furthermore, the need to address climate change will require integration with plans to improve air quality locally across the county.

The County AQS was initially drawn up in 2004 by the University of the West of England (UWE) on behalf of the GPG and was revised in 2011 following consultation with the Local Transport Plan Group within Gloucestershire County Council.

LAQM Progress Report 2014 30 Stroud District Council

5 Planning Applications

The Environmental Protection Section of Stroud District Council works in concert with Development Control to ensure that air quality issues are considered during the application stage of all relevant developments.

LAQM Progress Report 2014 31 Stroud District Council

6 Air Quality Planning Policies

Air quality is a material consideration in determining planning applications. Poor air quality can have detrimental impacts on health and the amenity of users of land in terms of odour, dust and nuisance.

The planning system has a key role in protecting people from unacceptable risks to their health and in providing an adequate protection to the amenity value of land. These considerations must however, be balanced against other aims of the planning system such as to secure economic regeneration and provide adequate levels of housing.

The National Planning Policy Framework is a key part of the government’s reforms to make the planning system less complex and more accessible. It vastly simplifies the number of policy pages about planning. The framework acts as guidance for local planning authorities and decision takers, both in drawing up plans and making decisions about planning applications. Previous guidance documents such as PPG23: Planning and Pollution Control have been repealed but are likely to still be referred to by local authorities and developers alike.

There is no Supplementary Planning Guidance (SPG) for air quality matters currently available within Stroud District Council.

7 Local Transport Plans and Strategies

The Local Transport Plan for Gloucestershire (LTP3) is produced by Gloucestershire County Council and sets out the transport strategy for the County from 2011 to 2026. Their vision for transport in the future is “providing a safe and sustainable transport network within Gloucestershire” where safe means a transport network that people feel safe and secure using and sustainable means a transport network that is both environmentally and financially sustainable.

One of the main objectives within the strategy is to provide a Cleaner Healthier County by improving air quality.

LAQM Progress Report 2014 33 Stroud District Council

8 Climate Change Strategies

The Council is committed to improving its environmental performance and has been accredited with ISO 14001 and Eco-Management and Audit Scheme (EMAS) since 1999. In 2007 the Council adopted an Environmental Strategy which set out the long term environmental priorities • Sustainable consumption and production – more for less • Climate Change and Energy – confronting our greatest threat • Protecting our natural resources and enhancing the environment – clean, green and safe • Keeping the council and local community focused on environment limits – lets not forget how important the issue is

Also in 2007 SDC adopted the Nottingham Declaration, set up an Independent Climate Change Panel and worked with the Local Strategic Partnership looking at the effects of Peak Oil and Climate Change.

In 2007/8 the Council signed up to the Carbon Trust - Carbon Management Programme. It sets out the key activities to deliver a 35% reduction in the Council’s own emissions from direct operations by the end of 2010/11.

A range of National Indicators were introduced in 2008 and included several environmental indicators – • NI 185 - Percentage CO2 reduction from LA operations • NI 186 – Per capita reduction in CO2 emissions in the LA area • NI 188 – Planning to adapt to Climate Change • NI 194 - Air quality - local air quality management • NI 196 - Improved street and environmental cleanliness – fly tipping • NI 195a - Improved street and environmental cleanliness - levels of litter • NI 195b - Improved street and environmental cleanliness - levels of detritus • NI 195c - Improved street and environmental cleanliness - levels of graffiti • NI 195d - Improved street and environmental cleanliness - levels of fly posting • NI 197 - Improved local biodiversity – active management of local sites

LAQM Progress Report 2014 34 Stroud District Council

The Carbon Management Programme is helping to reduce the CO2 emissions from council owned buildings. To help with reducing the NOx emissions from transport the Council is monitoring the emissions recorded in national indicator 194 and has undertaken the Energy Savings Trust - Green Fleet Review. In September 2009 SDC signed to the 10:10 campaign – reducing CO2 emissions by 10% in 2010.

The 7 Gloucestershire Councils have committed themselves under the Gloucestershire Local Area Agreement (LAA) to reach level 3 of National Indicator 188 by end of 2011/12. As at March 2010 all councils were at Level 2. All relevant documentation for NI 188 is available at http://www.stroud.gov.uk/docs/community/climate_change_glos.asp

9 Conclusions and Proposed Actions

9.1 Conclusions from New Monitoring Data

The primary pollutants of concern in Stroud District are traffic derived, in particular

NO 2 . Existing dwellings near to busy streets are known to be at risk and the Council continues to monitor via diffusion tubes.

The monitoring data shows that one site at Dudbridge marginally exceeds the annual

NO 2 air quality objective. Attempts have been made to install continuous automatic

NO 2 monitoring at this site in order to take more precise NO 2 measurements; however, due to the lack of a suitable power source this has not been possible.

Given the marginal exceedance of the NO 2 Air Quality Objective, NOx tubes will continue to be used at this site to indicate the NO2 levels.

Continuous automatic NO 2 monitoring was carried out at Bowbridge between 16/12/13 and 22/10/14. The results of this monitoring will be reported in the 2015 Updating and Screening Assessment.

9.2 Conclusions relating to New Local Developments

As stated previously the Environmental Protection Section of Stroud District Council works in concert with Development Control to ensure that air quality issues are considered during the application stage of all relevant developments.

9.3 Proposed Actions

The proposed future actions for the District are to:

1 Continue to closely monitor levels of NO 2 throughout the District

2 Complete and submit the 2015 Updating and Screening Assessment

Appendix F: Distance Attenuation Data

Background levels were obtained for the nearest grid reference to the three sites from the dataset for Stroud District Council obtained via: http://laqm.defra.gov.uk/maps/maps2010.html#2010BackgroundMaps

All relevant data was then input into the calculator available at: http://laqm.defra.gov.uk/documents/NO2withDistancefromRoadsCalculatorIssue4.xls to obtain the predicted levels at each of these sites as shown in Table 2.7.
