Relationship with other Plans and Programmes European level EU Directive 1996/62/EC on Ambient Air Quality sets the framework for dealing with local air pollution by introducing new air quality standards for previously unregulated pollutants. In addition, the 6th EU Environment Action Programme highlights strategic priorities of the Commission’s environmental policy, amongst others human health - an issue closed related to air pollution. At a national level, the UK Air Quality Strategy defines a number of air quality objectives for several pollutants, whilst PPS 23 ‘Planning and Pollution Control’ stresses the importance of the proximity principle in siting new developments and thereby separating incompatible land uses. 1.2. Baseline Information The monitoring of air quality is important in ensuring that levels of identified pollutants remain below national standards and targets. Local authorities are required to review and assess the concentrations of seven pollutants for national health-based objectives. These are: Carbon monoxide (CO); Nitrogen oxides (NOX); Benzene; 1,3-butadiene Lead; Particulate matter (PM10); and Sulphur dioxide (SO2). These pollutants are monitored because they can damage human health and the environment. For the purpose of this report, data on pollutant levels, and the number of days where air pollution was considered as moderate or high has been collected. This data has been compared to regional data and national targets. Table 1 shows relevant UK air quality standards and objectives1, derived from the 2007 UK Air Quality Strategy. These also include limit values set out by EU Daughter Directives on Air Quality. Table 1 - Selected AQ standards and objectives UK Air Quality Objectives for protection of human health, July 2007 Pollutant Air Quality Objective To be achieved by Concentration Measured as Benzene All authorities 16.25 µg m-3 Running annual mean 31 December 2003 England and Wales Only 5.00 µg m-3 Annual mean 31 December 2010 1,3-Butadiene 2.25 µg m-3 Running annual mean 31 December 2003 Carbon Monoxide England, Wales and N. 10.0 mg m-3 Maximum daily running 8- 31 December Ireland hour mean 2003 Lead 0.5 mg m-3 Annual mean 31 December 2004 0.25 mg m-3 Annual mean 31 December 2008 Nitrogen Dioxide 200 µg m-3 not to be 1-hour mean 31 December exceeded more than 18 2005 times a year 40 µg m-3 Annual mean 31 December 1 http://www.airquality.co.uk/archive/standards.php#std 1 UK Air Quality Objectives for protection of human health, July 2007 Pollutant Air Quality Objective To be achieved by Concentration Measured as 2005 Particles (PM10) (gravimetric) All authorities 50 µg m-3, not to be 24-hour mean 31 December exceeded more than 35 2004 times a year 40 µg m-3 Annual mean 31 December 2004 Sulphur dioxide 350 µg m-3, not to be 1-hour mean 31 December exceeded more than 24 2004 times a year 125 µg m-3, not to be 24-hour mean 31 December exceeded more than 3 2004 times a year 266 µg m-3, not to be 15-minute mean 31 December exceeded more than 35 2005 times a year Ozone 100 µg m-3 not to be 8-hour mean 31 December exceeded more than 10 2005 times a year Table 2 shows estimated and predicted pollutant levels2 in Watford Borough Council, St Albans City Council, Dacorum Borough Council, and Three Rivers District Council. The data was derived by calculating the average of the predictions for all sites in the Local Authority area. Data was not available for SO2 and CO levels in 2005 and 2010, and 1, 3-butadeine in 2010. The data below displays a general trend of decreasing pollutant levels between 2001 and 2010. Table 2 – Air Pollutant levels Pollutant Watford Borough Council 2001 2005 2010 NOX 65.04 53.51 40.97 NO2 34.20 29.90 24.89 PM10 21.74 20.92 19.01 SO2 3.6 - - Benzene 0.72 0.63 0.47 CO 0.42 - - 1, 3-butadeine 0.31 0.25 - Units: NOX (ugm-3 as NO2 annual mean); NO2 (ugm-3 annual mean); PM10 (ugm-3 grav. annual mean); SO2 (ugm-3 annual mean); Benzene (ugm-3 annual mean); CO (mgm-3 annual mean); 1, 3- butadeine (1, 3-butadiene 2001 ugm-3 annual mean) For comparison, Table 3 displays estimated pollutant level data for the East of England3. The data was derived by calculating the average of the predictions for all sites in the East of England. No data was available for benzene or 1, 3-butadeine. It can be seen that, for NOx in particular, Watford has below-average air quality for the region although the trend is equally towards improvement. However measurements at the Watford Town Hall area suggests NOx at 38 units, NO2 at 20 and PM10 at 17- suggesting better air quality in some pockets of the Borough. 2 Air Quality Archive: http://www.airquality.co.uk/archive/laqm/laqm.php 3 Air Quality Archive: http://www.airquality.co.uk/archive/data_and_statistics.php?action=exceedence_pre_step&go=Go 2 Table 3 - East of England region estimated air pollution East of England air pollution Pollutant 2001 2005 NOX 60.87 40.58 NO2 28.93 23.95 PM10 21.33 21 SO2 8.1 6.48 Benzene - - CO 0.4 0.24 1, 3-butadeine - - (Units as for table above) .A common presentation of air quality trends looks at the number of days in a year that a particular AQ standard or objective was exceeded. Table 4 shows this data for the years 2001 to 2006 for three pollutants, showing positive trends for particulates but a persistent problem regarding rural ozone.
