5.12 When comparing the predicted NO2 concentrations in 2024 with and without the proposed
development the impact is overall considered negligible or moderate depending on the location
of the modelled receptor.

5.13 When considering the proposed and committed development flows the impact is considered
negligible, slight, moderate or substantial, depending on the location of the modelled receptor.

5.14 Nitrogen dioxide also has an hourly objective of 200 μg/m not to be exceeded more than 18
times in one year. However, the hourly mean concentration has not been calculated directly
by ADMS-Roads model. This is as a result of an evaluation of continuous monitoring data
from across the UK that revealed that the relationship between the annual mean and hourly
