Guidance on Decision-making Thresholds for Air Pollution: Main Report and Technical Report 2021
Available here are two reports, a main report and a technical report, which together provide an evidentiary basis for decision-making thresholds (DMTs), to inform the assessment of air quality impacts on designated sites. These reports were commissioned by JNCC on behalf of the Inter-agency Air Pollution Group and Defra (Department for Environment, Food and Rural Affairs).
The Main Report provides decision-making criteria to inform the assessment of air quality impacts on designated conservation sites. The criteria are intended to be applied to individual sources to identify those for which a decision can be taken without the need for further assessment effort.
Readers wishing to scrutinise the underlying technical evidence basis for the approach set out in the Main Report are referred to the supporting Technical Report. The Technical Report describes the setting of decision-making criteria for air quality impacts to designated nature conservation sites. The criteria are intended to be applied to changes caused by individual plans and projects, thus removing the need to consider air quality effects further, including in combination with other plans and projects.
