In addition, the council also has 90 Nitrogen Dioxide Diffusion tubes located across the borough collecting data used to identify trends and hotspots, predict future pollutant levels, and monitor the success of the implementation of our air quality action plan.

Monthly results from the Diffusion Tube monitoring can be found bellow:

Environmental Permits

Some industries have potential to cause pollution. They are regulated under the Pollution Prevention and Control (PPC) regime, through the Environmental Permitting (England and Wales) Regulations 2010 (EPR). Some operators have to carry out monitoring in order to prove they are complying with their permit conditions. This might be in the form of frequent visual or olfactory observations; continuous emissions monitoring; and/or periodic manual extractive testing.
