ii Progress Report Southampton City Council September 2010

Executive Summary

Overall air quality in 2009 at all of our stations improved upon that monitored in 2008. This may, in part be attributable to the wet, windy summer weather we endured and economic recession. Hopefully it also reflects the success of the air quality action plan/local transport plan and improved emission reduction from newer vehicles helped by the government’s car scrappage scheme in 2009.

Southampton City Council has measured concentrations of nitrogen dioxide above the annual mean at relevant locations outside of the existing AQMAs , and will need to proceed to a Detailed Assessment, for

1. Burgess Road, west of the Avenue, on the south side of the Road residential properties close to the Kerb.

2. Victoria Road at the junction with Portsmouth Road, where there are residential flats above the shops close to the Kerb.

3. Princes Court, Northam Road, residential flats close to the Kerb.

4. St. Andrews Road, south of Charlotte Place Roundabout, residential properties close to the Kerb.

5. Consider extending the existing Romsey Road Air Quality Management Area (AQMA) to include 7 additional houses where monitoring in 2008/9 was just above the annual mean standard at a façade.

It is envisaged that the Detailed Assessments will mostly rely upon additional NOx tube monitoring at the locations listed above to determine whether the annual mean is exceeded consistently and the spatial distribution of a potential AQMA.

1.1 Description of Local Authority Area

Southampton is a south coast port city of 236,700 people (2009). The Deep Water Channel of Southampton Water links the City to the Solent and the English Channel. The City is bounded to the west by the River Test and the River Itchen runs through the eastern part of the City. Most of Southampton is relatively flat, close to sea level, but there are hills in the north of the City and in the east. As you approach Southampton from the M3 you drive past the University and down the Avenue with Southampton Common, a large wooded and grassy open recreational area to the west. The City has very good transport infrastructure links, served by a regional airport just outside the City’s northern boundary, the M3 and M27 Motorways and a main line railway to London and along the south coast.

The City of Southampton lies at the western end of the South Hampshire sub-region. The wider urban South Hampshire area, consisting of Southampton, Eastleigh, Fareham, Gosport, Portsmouth and Havant, together with parts of the New Forest, Test Valley, Winchester and East Hampshire has a combined population of 971,250 (2004 figure) and is the largest urban area in the South East region outside London. As a consequence, the area is also one of the South East’s major economic centres and whilst other successful areas in the region depend upon linkages to London, South Hampshire operates in a distinct and largely separate manner, relying instead on connections with other regions and with Europe as a result of the presence of two major ports (Southampton and Portsmouth).

The major sources of air pollution in Southampton are road transport emissions, especially Heavy Goods Vehicles (HGVs). Domestic gas boilers, Industrial emissions particularly from the waterside and shipping emissions also contribute towards the total.

1.2 Purpose of Progress Report

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.

6 Progress Report Southampton City Council September 2010 1.3 Air Quality Objectives

The air quality objectives applicable to Local Air Quality Management (LAQM) in England are set out in the Air Quality (England) Regulations 2000 (SI 928), and the Air Quality (England) (Amendment) Regulations 2002 (SI 3043). They are shown in Table 1.1. This table shows the objectives in units of microgrammes per cubic metre μg/m3 (for carbon monoxide the units used are milligrammes per cubic metre, mg/m3). Table 1.1. includes the number of permitted exceedences in any given year (where applicable).

1.4 Summary of Previous Review and Assessments

Southampton City Council finalised its 2nd Round Detailed Assessment in December 2004. The Council declared six Air Quality Management Areas (AQMAs) in July 2005.

AQMAs were declared in July 2005 at the following locations for nitrogen dioxide annual mean:

• Bitterne Road • Town Quay • Bevois Valley Road • Redbridge Road • Junction of Romsey Road and Winchester Road • Hill Lane, Winchester Road and The Avenue

Southampton City Council finalised its 3rd Round Detailed Assessment in December 2007, declaring two additional AQMAs in July 2008 and amending two existing AQMAs. The Detailed Assessment Report can be found on council’s website below, link below. http://www.southampton.gov.uk/Images/detailked%20assessment%202007_tcm46- 250132.pdf

AQMAs were declared in July 2008 at the following locations for exceedance of the nitrogen dioxide annual mean:

• Commercial Road • Millbrook Road

Amendments to existing AQMAs in July 2008

• The Winchester Road AQMA was dramatically reduced in size. • The Town Quay AQMA was extended slightly to include the junction to Ocean Village

In July 2009 the Further Assessment for the 2 new AQMAs declared in 2008 confirmed the declarations as valid. The Report recommended that the Millbrook Road AQMA to be extended westwards to include the NOx tube receptors that were above the annual mean standard in 2008. In July 2010 the licensing committee formally extended the Millbrook Road AQMA.

Southampton City Council is supplied Nitrogen Dioxide Tubes by Gradko Environmental of Winchester who also undertake the analysis. Gradko follows the procedures set out in the Harmonisation Practical Guidance. Gradko received a Good Category for the WASP Scheme Rounds 97-101. (end of April 2008).

Southampton City Council have utilised the 0.9 correction factor which was the 2009 national correction factor based on 33 co-location studies using gradko 20% TEA in water preparation method. Version 03/10. It was decided to use the national factor rather than the local co-location factor for consistency with the Further Assessment approach.

2.2 Comparison of Monitoring Results with Air Quality Objectives

2.2.1 Nitrogen Dioxide

Automatic Monitoring Data

Redbridge School Monitoring Station

The nitrogen dioxide annual mean was 39.9µg/m3, right on boundary of the 40µg/m3 standard, a decrease on 2008 when it was 44 µg/m3. A peak hour concentration of 161 µg /m3 was recorded, with no exceedance of the 1 Hour Standard. 87% data capture.

Bitterne Monitoring Station

The annual mean nitrogen dioxide level for 2009 was 34.4 ug/m3, an improvement on 2008 which was 39.2µg/m3 . A peak hour concentration of 145 µg/m3 was recorded with no exceedance of the 1 Hour Standard. 95% data capture.

AURN Brintons Road (Six Dials)

An annual mean of 35µg/m3 was recorded for nitrogen dioxide, a decrease of 1 µg/m3 from 2008 with a peak hour of 141µg/m3. There were no exceedances of the 1 hour standard. 96% data capture.

Onslow Road

Onslow Road recorded 44ug/m3 for nitrogen dioxide annual mean, a significant decrease compared to 2008’s 51.4 µg/m3, but still above the annual mean standard. There was 1, One Hour exceedance of the 200 ug/m3 standard, compared to 5 in 2008. This monitoring station is located within the Bevois Valley Air Quality Management Area. The station suffered from a prolonged power failure in late January, February and half of March, reducing data capture to only 83%. This was due to electrical problems from the adjacent lamp post where the power is sourced.

Millbrook Road

A mean of 50µg/m3 for nitrogen dioxide was recorded, well above the annual mean standard, but a small reduction on 2008. There were no exceedances of the One Hour Standard. The peak hour for this period was 142µg/m3. Data capture for 2009 was 98% a big improvement on 2008 when technical issues kept data capture below 90%.

30 Progress Report Southampton City Council September 2010 2.5 Discussion of 2009 diffusion tube data

2 Romsey Road is a relatively new site. It was relocated from across the junction from a lamp post that was not representative of relevant exposure to the façade of a small block of flats. 41.6 μg/m3 is slightly above the annual mean standard. We will proceed to a detailed assessment for this site this year. Additional diffusion tubes will be deployed to assess the extent of potential exceedance.

134 Romsey Road is just outside the existing AQMA. In 2009 the NOx tube on the residential façade increased from 40.5 μg/m3 to 43.8 μg/m3 The USA had already identified that it would probably be necessary to extend the AQMA to include these 7 additional terraced houses in the block, where 134 is.

54 and 57 Redbridge Road were new sites in 2009, just outside the Redbridge Road AQMAs. The tubes are located on residential facades. Both sites were slightly above the annual mean standard but the sites only commenced operating after the start of the year with 66% and 33% data capture for the calendar year. We will continue to monitor at these locations in 2010 to see if exceedance occurs.

The Hill Lane NOx Tube site is not within an AQMA, but the nearest receptor is 7m from the tube location situated on a lamp post 1m from the kerb. Using the procedure specified in Box 2.3 of TG(09) the estimated annual mean at the receptor was calculated to be 36.6 μg/m3 .

Princes Court, 66 Burgess Road, Victoria Road and St.Andrews Road had already been identified from the USA as proceeding to a detailed assessment based on 2008 NOx tube data.

PM10 Monitoring Adjustment

The PM10 monitoring data was gathered by 3 TEOM analysers. In late 2007 the Brintons Road AURN Station was upgraded to FDMS to gain gravimetric equivalence. 2009 data at Redbridge and Bitterne still used the standard TEOM instrument. It was decided to continue using the TEOMs without FDMS as the cost to upgrade was prohibitive and both stations are well below the air quality

standards for PM10 anyway.

The 2008 and 2009 data was corrected using the Volatile Correction Model (VCM) available from the VCM Web Portal www.volatile-correction-model.info

PM10 annual mean and days of exceedance has shown a marked reduction from 2007-2009.

3 New Local Developments

Southampton City Council confirms that there are no new local developments which may have an impact on air quality within the Local Authority area since the 2009 USA. Work has started on the Centenary Quay redevelopment of the Vosper shipyard in Woolston. This development has already been assessed for air quality impact. A Section 106 agreement is in place to monitor air quality at the Victoria Road junction during construction and occupation of the mixed use residential/commercial development. It is hoped that a new one way system paid for by the developer will reduce traffic congestion at the junction where NOx tubes have identified levels close to the NO2 annual mean.

3.1 Road Traffic Sources

Southampton City Council confirms that there are no new road traffic sources which may have an impact on air quality within the Local Authority area since the last USA.

3.2 Other Transport Sources

Southampton City Council confirms that there are no other transport sources since the 2009 USA which may have an impact on air quality within the Local Authority area.

. 3.3 Industrial Sources

A Planning application is likely to be submitted for a 100 MW biomass station in Southampton Docks. Likely to require an EIA and Environment Agency permit.

These will be taken into consideration in the next Updating and Screening Assessment, scheduled for 2012.

38 Progress Report Southampton City Council September 2010

3.4 Commercial and Domestic Sources

Southampton City Council confirms that there are no new significant commercial and domestic sources since the 2009 USA which may have an impact on air quality within the Local Authority area.

3.5 New Developments with Fugitive or Uncontrolled Sources

Southampton City Council confirms that there are no new developments with fugitive or uncontrolled sources which may have an impact on air quality within the Local Authority area.

4 Air Quality Planning Policies

Local Plan 2006

SDP 15 Air Quality Planning permission will be refused: (i) where the effect of the proposal would contribute significantly to the exceedence of the National Air Quality Strategy Standards; or (ii) where the proposal would be materially affected by existing and continuous poor air quality.

Large potentially polluting developments will be required to assess their air quality impact by detailed air dispersion modelling and appropriate monitoring.

As well as a detrimental impact upon the natural environment, air pollution if unchecked will have an increasing impact on people’s health and their quality of life. The Government through the National Air Quality Strategy has set a challenging number of objectives to reduce air pollution and to ensure that air quality continues to improve in the long term. The Strategy has set targets to reduce seven of the eight main air pollutants to 2003 and beyond.

The City Council’s local air quality assessments will provide information on trends in air quality over time and this will help to identify where constraints are necessary on developments in particular areas arising from the cumulative impact of existing and future polluting uses of land. Air quality standards cover such pollutants as particulates and nitrogen dioxide.

Large, potentially polluting developments include those that generate a significant amount of vehicle movements (such as large out of town industrial, leisure, retail, or office developments), industrial processing plants, power stations and incinerators. The impact of any proposals on ambient air quality will also be important where the development could in itself result in the designation of Air Quality Management Areas or conflict/ render unworkable elements of any Air Quality Action Plans produced by the Council. In appropriate circumstances, air quality impact studies through air dispersions modelling and appropriate monitoring will be made legally binding through the use of planning conditions or section 106 agreements. Account will be taken of any Air Quality Management Areas and Action Plans declared by the city council.

The Onslow Road station suffered from a prolonged power failure in late January, February and half of March, reducing data capture to only 83%. This was due to electrical problems from the adjacent lamp post where the power is sourced.

Millbrook Road Monitoring Station is owned by Marchwood Power Station who use Enviro Technology for site calibrations and Kings College for data ratification.
