LOCAL ENVIRONMENTAL CONCERNS - AIR QUALITY Port Talbot already suffers high levels of air pollution from the local steelworks. For a number of years Port Talbot has failed EU air quality directives for particulates and also polyaromatic hydrocarbons (a carcinogenic emission caused by burning processes). Particulate matter smaller than 10 microns (PM10) damages the pulmonary system (heart and lungs) and reduces live expectancy. The graph below shows the last ten years of PM10 air quality experienced in Port Talbot. [The EU legal requirement, is the horizontal line shown in red].The town is also subject to high nitrogen dioxide levels, sulphur dioxide a lot of iron ore dust, coal dust,and industrial noise as well as a host of toxic emissions such as lead and cadmium.
Although in the last few years there has been a noticeable improvement in air quality, overall this improvement has to be put into the context, namely that there has been an economic downturn and reduced activity in the steelworks. The high potential for pollution still exists, as was recently demonstrated on the 6th February 2011, when monitored PM10 levels for the day were over three times the allowable daily limit. This pollution event was one of the worst incidents recorded since monitoring began back in 1997.The problem with developing further heavy industry in Port Talbot is that the location is surrounded by steep hills (rising up 300m) that trap in the air pollution. It is against this backdrop that PT-RAPS feels it is plainly wrong and unjust to build further power stations here. Currently there are two commercial power stations operating that supply the National Grid Network and three Tata owned power stations that power the steelworks, making five in all. In addition to these five power stations there are three more either consented, or being considered in planning. If these are all built it would give Port Talbot, a town of just 60,000 people, eight separate power stations totalling around 2GW generating capacity. or enough to power the whole of Wales.
