Southampton City Council September 2010 2010 Air Quality Progress Report Southampton City Council In fulfillment of Part IV of the Environment Act 1995 Local Air Quality Management September 2010 Progress Report i Southampton City Council September 2010 Local Simon Hartill Authority Officer Department Environmental Health Address One Guildhall Square Floor 5, Environmental Health Southampton SO14 7FP Telephone 023 8091 7531 e-mail [email protected] Report PR3 Reference number Date August 2010 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.

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).

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.
