Under the Environment Act1995 PART IV, Babergh DC is conducting a Consultation on a DRAFT AIR QUALITY ACTION PLAN FOR CROSS STREET (A131), SUDBURY.
To summarise the key points are:
Nitrogen dioxide is an air pollutant formed when nitrogen oxides from burning fuels react in the air, such as occurs in road vehicle exhaust fumes. NO2 can have both short-term and long-term effects. The short-term effects can include irritation of the eyes, nose and throat and can increase the symptoms of existing respiratory conditions such as asthma, bronchitis or emphysema. However, these health effects do not normally occur at typical levels of NO2 experienced in Cross Street. The concern is long-term exposure at homes in the AQMA which could contribute to the gradual deterioration in health of people who are already suffering from respiratory problems or heart conditions and could cause an increased susceptibility to respiratory infections amongst healthy individuals.
Despite making up a just 7% of the total traffic volume on Cross Street, Heavy Goods Vehicles (HGVs) have the largest impact, accounting for up to 46% of annual mean NO2 concentrations. Therefore measures that minimise HGV emissions are potentially important. The ambient background concentration and emissions from cars also contribute a significant proportion to the overall concentration.
A 20% reduction in the annual mean NO2 concentration at the worst measured location is necessary in order to achieve the Annual Average Objective.
One of these measures has already been implemented and its effectiveness assessed – namely the removal of the former build-out at the southern end of Cross Street.
Measurements confirm that properties which are located adjacent to the build-out, experienced an increase in concentrations in the 12 months following the removal, while the site located opposite the build-out (where concentrations were significantly above the Objective), experienced a reduction in concentrations. This is likely to be due to the change in the road centre-line moving traffic away from one side of the road and closer to the other. Overall the removal of the build-out reduced the margin of exceedence of the Air Quality Objective in the immediate vicinity, which is the primary aim of the Action Plan. A number of locations further from the build-out also experienced reductions in concentrations after the removal of the build-out, which could be due to a reduction in traffic queue lengths.
Another measure proposed in the draft Action Plan is an Experimental Traffic Regulation Order to remove the parking bays at the northern end of Cross Street. Removing the parking bays would also further reduce acceleration/deceleration and queuing along Cross Street, contributing to lower emissions and hence a reduction in concentrations at most locations.
HGVs account for a major part of the traffic emissions on Cross Street, but the road is part of the strategic lorry network in Suffolk/Essex and therefore potential measures to restrict HGV traffic are limited. It may also be possible to introduce a one-way system for HGVs.
Have your say….
The draft Air Quality Action Plan for Cross Street is open for public consultation until Monday 30 January 2012. The Council would be pleased to receive your views on it, in particular:
Are you satisfied that the draft plan accurately reflects the causes of poor local air quality in Cross Street?
What additional actions would you like to see included in the final Action Plan?
What actions do you feel should be removed from the draft Action Plan?
You can view the full draft Action Plan on-line at: www.babergh.gov.uk/babergh/airqualitymanagement, or in reception at Sudbury Town Council, Old Market Place, Sudbury.

There are some potentially controversial proposals here on the residents, business and local school. Please get in touch with your views to both the officers and myself.
