LAQM Annual Status Report 2017 South Hams and West Devon Councils

Executive Summary: Air Quality in Our Area Air Quality in South Hams and West Devon

Air pollution is associated with a number of adverse health impacts. It is recognised as a contributing factor in the onset of heart disease and cancer. Additionally, air pollution particularly affects the most vulnerable in society: children and older people, and those with heart and lung conditions. There is also often a strong correlation with equalities issues, because areas with poor air quality are also often the less affluent areas1,2.

The annual health cost to society of the impacts of particulate matter alone in the UK is estimated to be around £16 billion3.

Within the South Hams area there are 3 Air Quality Management Areas, these are located within the towns of Totnes and , and adjacent to the A38 at Dean Prior. The main pollutant of concern is Nitrogen Dioxide associated with road traffic pollution.

The monitoring has shown no meaningful improvements in the air quality levels prior to 2016. The 2015 results did appear slightly better, however the 2016 figures increased back to the trend levels.

There are no Air Quality Management Areas (AQMA) within West Devon, however the 2016 monitoring on Road in has shown regular exceedances of NO2. Further monitoring locations on this road commenced in the latter part of 2016, and once we have determined the extent of the area where the levels are in exceedances of NO2 are determined we will seek to determine an Air Quality Management Area.

Actions to Improve Air Quality

Since the amendment to the Air Quality Management Order in 2016 the Council has been working on a new Clean Air Strategy for the two authority areas, including an air quality action plan for the three locations. This is currently in draft but we hope to put it out for public and statutory consultation in 2017.

LAQM Annual Status Report 2017 i South Hams and West Devon Councils

The clean air strategy also seeks to adopt a supplementary planning document,

Conclusions and Priorities

The trends have shown no improvements in air quality in time as was expected due to improvements in engine technology. The main priority in the next 12 months is to consult on the proposed Clean Air Quality Strategy to South Hams and West Devon with the public and statutory consultees.

In West Devon the principle priority will be to determine the need and extent of a potential Air Quality Management Area in Exeter Road, Okehampton.

LAQM Annual Status Report 2017 iv South Hams and West Devon Councils

1 Local Air Quality Management This report provides an overview of air quality in South Hams and West Devon during 2016. It fulfils the requirements of Local Air Quality Management (LAQM) as set out in Part IV of the Environment Act (1995) 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 an exceedance is considered likely the local authority must 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. This Annual Status Report (ASR) is an annual requirement showing the strategies employed by South Hams and West Devon to improve air quality and any progress that has been made.

The statutory air quality objectives applicable to LAQM in England can be found in Table E.1 in Appendix E.

LAQM Annual Status Report 2017 1 South Hams and West Devon Councils

2 Actions to Improve Air Quality 2.1 Air Quality Management Areas

Air Quality Management Areas (AQMAs) are declared when there is an exceedance or likely exceedance of an air quality objective. After declaration, the authority must prepare an Air Quality Action Plan (AQAP) within 12-18 months setting out measures it intends to put in place in pursuit of compliance with the objectives.

A summary of AQMAs declared by South Hams District Council can be found on the next page. Further information related to declared or revoked AQMAs, including maps of AQMA boundaries are available online at https://uk- air.defra.gov.uk/aqma/local-authorities?la_id=239. Alternatively, see Appendix D: Map(s) of Monitoring Locations and AQMAs, which provides for a map of air quality monitoring locations in relation to the AQMA(s).

2.2 Progress and Impact of Measures to address Air Quality in South Hams District Council and West Devon Borough Council

Defra’s appraisal of last year’s ASR concluded “An Action Plan has been developed in 2013 for measures to address the AQMAs in Ivybridge and Totnes. The extent of the AQMA has recently been extended in Totnes to account for an additional area of exceedance, however there appears no report received by Defra of changes to the original AQMA declared in 2009. The report highlights two single measured points of exceedance, one within the extended Totnes AQMA, and the other within the small area AQMA near the A38 at Dean Prior. On the basis of the evidence provided by the local authority the conclusions reached are acceptable for all sources and pollutants, with the provisos listed in the commentary below.”

The Council has now submitted the amended AQMA Order for Totnes to DEFRA.

South Hams District and West Devon Borough Councils have been actively working on a revised air quality strategy, which includes revised Air Quality Action Plans, a supplementary planning guidance document, and a revision to the validation checklist to bring it in line with the revised IAQM guidance, this will all contained within a single Clean Air Strategy for South Hams and West Devon.

The Councils expect the following measures to be completed over the course of the next reporting year: adoption of a clean air strategy for South Hams and West Devon following public and statutory consultation, and the implementation of the supplementary planning guidance.

The principal challenges and barriers to implementation that South Hams and West Devon anticipates facing are a lack of support to consulting on the clean air strategy due to the Councils currently consulting on a proposed joint local plan. This is causing the public to object to new housing developments due to air quality impacts.

Whilst the measures stated above will help to contribute towards compliance, South Hams District Council anticipates that further additional measures not yet prescribed will be required in subsequent years to achieve compliance and enable the revocation of all of the AQMAs.

2.3 PM2.5 – Local Authority Approach to Reducing Emissions and/or Concentrations

As detailed in Policy Guidance LAQM.PG16 (Chapter 7), local authorities are expected to work towards reducing emissions and/or concentrations of PM2.5 (particulate matter with an aerodynamic diameter of 2.5µm or less). There is clear evidence that PM2.5 has a significant impact on human health, including premature mortality, allergic reactions, and cardiovascular diseases.

South Hams and West Devon Councils are taking the following measures to address

PM2.5: we are working on a clean air strategy for both Councils this is likely to detail promotion of non-private car alternatives, as well as requiring the facilitation of ultra- low emission vehicle infrastructure on all new residential developments.

LAQM Annual Status Report 2017 5 South Hams and West Devon Councils 3 Air Quality Monitoring Data and Comparison with Air Quality Objectives and National Compliance 3.1 Summary of Monitoring Undertaken

3.1.1 Automatic Monitoring Sites

Neither South Hams nor West Devon have any automatic (continuous) monitoring sites. The last automatic monitoring for NO2 undertaken in the South Hams was in 2013 when a nitrogen Dioxide chemiluminescent analyser was in operation on

Bridgetown Hill, Totnes. A PM10 ‘screening’ analyser (an Osiris) was also in operation at the same location until 2014, for results see previous submitted air quality reports.

3.1.2 Non-Automatic Monitoring Sites

South Hams District Council undertook non- automatic (passive) monitoring of NO2 at 28 sites during 2016. Table A.2 Details of Non-Automatic Monitoring Sites

in Appendix A shows the details of the sites.

West Devon Borough Council undertook non- automatic (passive) monitoring of NO2 at 6 sites during 2016.

Maps showing the location of the monitoring sites are provided in Appendix D. Further details on Quality Assurance/Quality Control (QA/QC) for the diffusion tubes, including bias adjustments and any other adjustments applied (e.g. “annualisation” and/or distance correction), are included in Appendix C.

3.2 Individual Pollutants

The air quality monitoring results presented in this section are, where relevant, adjusted for bias, “annualisation” and distance correction. Further details on adjustments are provided in Appendix C.

3.2.1 Nitrogen Dioxide (NO2)

Table A.3 – Annual Mean NO2 Monitoring Results in Appendix A compares the ratified and adjusted monitored NO2 annual mean concentrations for the past 5 years with the air quality objective of 40µg/m3.

LAQM Annual Status Report 2017 6 South Hams and West Devon Councils

For diffusion tubes, the full 2016 dataset of monthly mean values is provided in Appendix B.

There are 2 locations within Totnes where the annual mean is greater than the objective level, these being locations TSH5 and TSH12 (42.1and 52.1 µg/m3 respectively).

At Ivybridge levels on Western Road, Ivybridge have returned to be above the objective levels at monitoring location ISH5 (Western Road terrace), last year the levels had dropped to 38.1 µg/m3.

Levels at Dean Prior continue to breach the objective levels, with monitoring location DPSH2 being 69.6µg/m3. This would be a positive indication that there is the potential for the 1-hour mean objective to be breached.

Due to the limited roadside space, and the fact that there is only a single sensitive receptor there is no intention for South Hams District Council to commence automated continuous monitoring at this location. This location being adjacent to the Devon Express Way A38, it is unlikely that traffic flows will vary during the day or night, and therefore it is also unlikely that NO2 levels will fluctuate dramatically.

Monitoring recommenced in the latter part of 2016 in West Devon, and due to the low number of results it is too early to make any firm views in this area, however the results for OWD2 (East Street, Okehampton) are concerning and we have increased the number of diffusion tubes in this area, and we will keep the need to declare an AQMA under regular review.

The trend data shows that apart from 2015, the NO2 appear to be fairly consistent and certainly the expected reductions in levels have not materialised with improvements in vehicle emission technology see Figures A.1 – A.3.

3.2.2 Particulate Matter (PM10)

Neither the annual mean nor the 24 hour mean objectives were exceeded as measured by the Osiris monitor on Bridgetown Hill up until 2014. The results obtained were included in the 2015 Updating and Screening Assessment (SHDC 2015) and it is not thought to be worthwhile to reproduce the results in the Appendix to this report. As noted above, access to the 2015 USA is available via South Hams District Council Environmental Health.

3.2.3 Particulate Matter (PM2.5)

The Councils have not undertaken any monitoring of PM2.5 in 2016.

3.2.4 Sulphur Dioxide (SO2)

The Councils have not undertaken any monitoring of SO2 in 2016
