This plan must set out what measures the authority intends to introduce in pursuit of the Air Quality Objectives. Air Quality Objective Policy targets generally expressed as a maximum ambient concentration to be achieved, either without exception or with a permitted number of exceedences within a specified timescale (see also air quality standard). Air Quality Standard The concentrations of pollutants in the atmosphere which can broadly be taken to achieve a certain level of environmental quality. The standards are based on assessment of the effects of each pollutant on human health including the effects on sensitive sub groups (see also Air Quality Objective). Annual mean The average of the concentrations measured for each pollutant for one year. In the case of the Air Quality Objectives this is for a calendar year. AQMA Air Quality Management Area, an area which a local authority has designated for action, based upon predicted exceedences of Air Quality Objectives. AURN Automatic Urban and Rural Network of air pollution measurement sites, managed by contractors on behalf of Defra and the Devolved Administrations. Exceedence A period of time where the concentration of a pollutant is greater than the appropriate Air Quality Objective. Fine particles, particulate matter, PM10 Particles in air with an (equivalent aerodynamic) diameter of ten micrometres (10 µm, 10 micrometres) or less. Micrometre (µm) (also referred to as a micron) one millionth of a metre. 3 mg/m (milligrammes per cubic metre of air) A unit for describing the concentration of air pollutants in the atmosphere, as a mass of pollutant per unit volume of clean air. This unit is one thousand times larger than the µg/m3 unit listed below. 3 µg/m (microgrammes per cubic metre of air) A measure of concentration 3 in terms of mass per unit volume. A concentration of 1 µg/m means that one cubic metre of air contains one microgram (millionth of a gram) of pollutant. Shropshire Progress Report 2008 ; Page 4 of 92 Running mean is a mean – or series of means – calculated for overlapping time periods, and is used in the calculation of several of the National Air Quality Objectives. For instance, an 8-hour running mean is calculated every hour, and averages the values for eight hours. The period of averaging is stepped forward by one hour for each value, so running mean values are given for the periods 00:00 – 07:59, 01:00 – 08:59 etc. By contrast a non-overlapping mean is calculated for consecutive time periods, giving values for the periods 00:00 – 07:59, 08:00 – 15:59 and so on. There are, therefore, 24 possible running 8-hour means in a day (calculated from hourly data) and 3 non-overlapping 8-hour means. TEOM Tapering Element Oscillating Microbalance. Equipment used for measuring fine particulate matter such as PM10. Shropshire Progress Report 2008 ; Page 5 of 92 1: Introduction 1.1: Part IV of the Environment Act 1995 places a duty on local authorities to periodically review and assess the quality of air within their area. This report takes account of the government policy1 and technical2 guidance for local authorities carrying out their Local Air Quality Management (LAQM) duties. 1.2: The overall aim of the progress report in line with government guidance is to: • report progress on implementing local air quality management; and • report progress in achieving, or in many cases maintaining, concentrations below the air quality objectives. 1.3: This report contains information from the following six members of the Shropshire Local Air Quality Management group: a) Bridgnorth District Council (BDC) b) North Shropshire District Council (NSDC) c) Oswestry Borough Council (OBC) d) Shrewsbury & Atcham Borough Council (SABC) e) South Shropshire District Council (SSDC) f) Telford & Wrekin Council (TWC) 2: Summary of Previous Reviews 2.1: The group published an Updating and Screening Assessment (USA) of local air quality in June 2006. This concluded the following: a) Bridgnorth District Council • No detailed assessment required for Carbon Monoxide, Benzene, 1-3 Butadiene, Lead, Sulphur Dioxide or PM10. • Provisional annual PM10 objectives for 2010 are predicted to be exceeded and therefore further assessment of PM10 maybe required in the future if included in the Regulations. • A detailed assessment for Nitrogen Dioxide is required at two locations outside the AQMA, Whitburn Street and Lavington Court, where exceedences of the 2005 Objective have been measured. • It is recommended that the Council continue with its monitoring programme of nitrogen dioxide. 1 Local Air Quality Management Policy Guidance LAQM.PG(03): Defra 2003 2 Local Air Quality Management Technical Guidance LAQM.TG(03): Defra 2003 Shropshire Progress Report 2008 ; Page 6 of 92 b) North Shropshire District Council • No detailed assessment required for Carbon Monoxide, Benzene, 1-3 Butadiene, Lead, Nitrogen Dioxide, Sulphur Dioxide or PM10. • Provisional annual PM10 objectives for 2010 are predicted to be exceeded and therefore further assessment of PM10 maybe required in the future if included in the Regulations. • It is recommended that the Council continue with its monitoring programme of nitrogen dioxide. c) Oswestry Borough Council • No detailed assessment required for Carbon Monoxide, Benzene, 1-3 Butadiene, Lead, Nitrogen Dioxide, Sulphur Dioxide or PM10. • Provisional annual PM10 objectives for 2010 are predicted to be exceeded and therefore further assessment of PM10 maybe required in the future if included in the Regulations. • It is recommended that the Council continue with its monitoring programme of nitrogen dioxide. d) Shrewsbury and Atcham Borough Council • No detailed assessment required for Carbon Monoxide, Benzene, 1-3 Butadiene, Lead, Nitrogen Dioxide, Sulphur Dioxide or PM10. • Exceedences of objective limits of Nitrogen Dioxide are measured and predicted at a number of busy roads and junctions in the Borough, although all fall within the boundaries of the existing AQMA and therefore a detailed assessment of Nitrogen Dioxide is not required. • Provisional annual PM10 objectives for 2010 are predicted to be exceeded and therefore further assessment of PM10 maybe required in the future if included in the Regulations. • It is recommended that the Council continue with its monitoring programme of nitrogen dioxide. e) South Shropshire District Council • A detailed assessment required for Benzene at a residential property close to a petrol station • A detailed assessment required for Nitrogen Dioxide from road traffic in Ludlow and Craven Arms • No detailed assessment required for Carbon Monoxide, 1-3 Butadiene, Lead, Sulphur Dioxide or PM10. Shropshire Progress Report 2008 ; Page 7 of 92 f) Telford and Wrekin Council • No detailed assessment required for Carbon Monoxide, Benzene, 1-3 Butadiene, Lead, Nitrogen Dioxide, Sulphur Dioxide or PM10. • Provisional annual PM10 objectives for 2010 are predicted to be exceeded and therefore further assessment of PM10 maybe required in the future if included in the Regulations. • It is recommended that the Council continue with its monitoring programme of nitrogen dioxide. 2.2: The full USA report can be viewed and downloaded at: www.northshropshiredc.gov.uk/static/page249.htm 2.2: As a result of the USA Bridgnorth and South Shropshire District Councils undertook the following detailed assessments:- a) Bridgnorth District Council • A Further Assessment of the Air Quality Management Area was carried out in 2006. The Further Assessment revealed that the NO2 levels in the AQMA are still likely to exceed the annual mean Air Quality Strategy Objective. • A Detailed Assessment has been carried out for Underhill Street, Bridgnorth and this confirmed that the NO2 annual average AQS objective was likely to be exceeded.
