3 Air Quality3.1 Findings at Stage 2 AssessmentThe Stage 2 assessment indicated that during construction phase of the PreferredVersion, there would be the potential for intermittent dust impacts at sensitivereceptors depending on meteorological conditions. The impact rating indicated thatdust nuisance would be temporary, medium term and local in effect. It is consideredtherefore, that impacts would be of a slight adverse significance, once mitigationmeasures are implemented.During the operational phase of the Preferred Version, the assessment indicated thatair quality would not cause any exceedence of the annual mean objective limit foreither NO2 or PM10.3.2 Reason for Scoping outThe DMRB Simple Level Assessment carried out at stage 2 demonstrated that whilstthe proposed scheme is predicted to result in small to medium increases in pollutantconcentrations (neutral to moderate adverse) there would be no exceedence of thehuman-health based national air quality objectives for the two characteristic roadrelatedpollutants, nitrogen dioxide (NO2), or particulate matter (PM10), nor anyaffect on areas currently designated for poor air quality (termed an Air QualityManagement Area). Regional emissions are predicted to deteriorate with regards toNOX, PM10 and C with the Preferred Version.It was therefore considered that there would be no significant impacts as a result ofthe proposals and that no further assessment is required.25
