Introduction The Welsh Government issued a Short Term Competent Authority Action Plan (STCAAP) for Particulate Matter below 10 microns in diameter (PM10) in the Swansea Urban area (which includes Neath Port Talbot) in 2008. That plan was prepared pursuant to the requirements imposed on the Welsh Ministers by regulation 11 of the Air Quality Standards (Wales) Regulations 2007. Regulation 11 required the Welsh Ministers to produce an action plan indicating the short term measures to be taken within any zone in the event of circumstances in which the Welsh Ministers consider there is a risk that one of the following will be exceeded: (a) a limit value1; (b) the alert threshold for nitrogen or sulphur dioxide2; or (c) the alert threshold for ozone3. Based on monitoring data, the Welsh Ministers considered there was a risk of the PM10 limit value being exceeded in the South Wales Zone, in particular the Neath Port Talbot area. The 2008 Short Term Competent Authority Action Plan (STCAAP) indicates the measures to be taken within that zone: • to reduce the risk that a relevant limit value or alert threshold will be exceeded; or • where it is not possible to prevent the occurrence, to limit its duration or severity. There is no longer a legal requirement for a STCAAP. The Air Quality Standards (Wales) Regulations 2010 have replaced the 2007 Regulations. Part 5 article 21 (5) states that a Short–Term Action Plan (STAP) may be drawn up where there is 1 see Schedule 1 of the 2007 Regulations for the limit values of Group A pollutants which are available at: http://www.legislation.gov.uk/wsi/2007/717/schedule/1/made 2 see Schedule 2 of the 2007 Regulations for the alert thresholds which are available at: http://www.legislation.gov.uk/wsi/2007/717/schedule/3/made 3 see regulation 11(2), (3) and (4) of the 2007 Regulations which are available at: http://www.opsi.gov.uk/legislation/wales/wsi2007/wsi_20070717_en_1 Page 2 of 43 Clean Air for Port Talbot Short Term Action Plan 2012. a risk that any of the limit values (for example PM10) will be exceeded. However the Welsh Government sees it as an essential tool in improving air quality in Port Talbot. Since the 2008 STCAAP was published there have been developments in the understanding of air pollution in Port Talbot: • The Welsh Government commissioned an independent study to review the work undertaken in respect of PM10 pollution in the Neath Port Talbot area since 2000. This was carried out by the University of the West of England (UWE) and published in 2009. The study also provided advice to the Welsh Ministers on further measures to pinpoint sources of Particulate Matter. (See Appendix 2) • In 2010, the Welsh Government asked the Air Quality Expert Group (AQEG) to provide an independent expert opinion on: (See Appendix 3) “What methodologies or approaches are required to advance the evidence base in order to assess the impact of the different current particle sources within the Port Talbot area on the resultant Particulate Matter (PM) levels in the local area?” • A key component of the 2008 short term action plan was for the environmental regulators to review the environmental permits held at Port Talbot steelworks for Particulate Matter emissions. (See Appendix 4) The Welsh Government, the regulators (Natural Resources Wales (NRW), Neath Port Talbot County Borough Council (NPTCBC)) and industry operators are working in partnership to implement the recommendations from these reviews. In light of these developments the Welsh Government has updated and revised the 2008 STCAAP to produce this Clean Air for Port Talbot Short Term Action Plan. The role of this plan is to show the actions, over and above the day to day existing activities, that will be taken where there is a risk of exceedence. This is to be a dynamic and evolving document to ensure that the findings from any future studies can be incorporated when appropriate.

This plan will also be the sign posting to other information, reports and action plans working towards improving air quality in Port Talbot. 2. Background Historically, Port Talbot has a high level of pollution that is generally attributed to the industrial nature of the area. The large industrial complex that operates at the boundary of the Air Quality Management Area (AQMA) is recognised as a potentially major contributor. This industrial complex is shown in Figure 1. Fugitive emissions from the industrial site are also likely to be a significant factor. In addition, there are also emissions derived from other industrial installations outside of this complex, road transport, domestic sources, construction projects, natural sources (such as sea spray) and transboundary sources. A combination of these potential sources in the Port Talbot area has led to difficulties in meeting the air quality standards for PM10 since their introduction in the Air Quality Strategy 2000, later revised in 2007. There are specific requirements for local authorities to make improvements in local air quality. In addition, the Welsh Ministers have ongoing concerns of the potential risk that concentrations of PM10 within Port Talbot may exceed the relevant daily mean limit value set in Directive 2008/50/EC on ambient air quality and cleaner air for Europe and transposed in the Air Quality Standards (Wales) Regulations 2010. Both the standard and the limit value state that the daily mean concentration of 50 µg/m3 is not to be exceeded more than 35 times in a calendar year.

Making information on air pollution levels available to the public Pollutants covered by Directive 2008/50/EC on ambient air quality and cleaner air for Europe are monitored by the Automatic Urban and Rural Monitoring Network (AURN) and by other monitors, including local authority sites, affiliated to the AURN. Data from these monitors are made publicly available. They are continuously assessed in detail by air quality experts under contract to the Welsh Government, including by formal periodic quality assurance audits, to ensure their accuracy and robustness The Welsh Ministers make available to the public up-to-date information regarding zones, concentrations, and alerts of breaches of air quality standards through the UK Air Quality website and the Welsh Air Quality Website which may be found at the following links: Welsh air quality website: http://www.welshairquality.co.uk UK air quality website: http://www.airquality.co.uk Notwithstanding that data from the AURN system and affiliated sites require expert validation and calibration before it can be regarded as a completely reliable assessment of air quality and the potential for exceedences, the Welsh Ministers will consider all the available data from AURN sites in assessing the risk that a relevant limit value or alert threshold will be exceeded. Data from other relevant monitoring sites outside of the AURN may also be considered where operation of instruments and quality assurance of data is also completed to a proven high standard. However, AURN sites only can be used to provide official comparison with statutory limit values. This is due to an assurance that the instruments used, data management and quality assurance systems applied in the AURN meet strict Directive 2008/50/EC on ambient air quality and cleaner air for Europe requirements.
