Operational Phase

4.31 The guidance released by Environmental Protection UK provides steps for a Local Authority
to follow in order to assess the significance of air quality impacts of a development proposal.
This procedure, shown in Figure 8, has also been applied to the modelled results.

4.32 The joint guidance released by EPUK and the IAQM provides impact descriptors for individual
receptors. These descriptors are provided in Table 9.

Table 9 – Impact Descriptors for Individual Receptors

Long term average concentration % Change in concentration relative to AQ objective
at receptor in assessment year 1% 2-5% 6-10% >10%
75% or less of AQ objective Negligible Negligible Slight Moderate

76-94% of AQ objective Negligible Slight Moderate Moderate

95-102% of AQ objective Slight Moderate Moderate Substantial

103-109% of AQ objective Moderate Moderate Substantial Substantial

110% or more of AQ objective Moderate Substantial Substantial Substantial
