standard-practice of sheeting and covering any trucks and using wheel brushes
would minimise this impact.
Whilst long-term dust exposure can lead to human health impacts, including asthma,
such impacts from this proposal would be unlikely. More likely would be the potential
for localised nuisance in the form of minor and temporary dust deposition on outside
dining and seating areas, building frontages and parked cars.
Equipment emissions
Emissions-generating construction equipment (refer to section 3.3.5) may need to
operate within restricted spaces within the city centre adjacent to building frontages
for a number of consecutive days during construction. Whilst it would not impact on
the air quality of the road corridor it may have an effect on immediately adjacent
locations where ‘significant numbers of people congregate’ (eg ground-floor cafés,
restaurants, hotel lobbies). This would be managed through the controls described
below in Table 6-63.
Emissions associated with construction traffic delays
When traffic idles and queues, engine performance is compromised and fuel burns
less efficiently, leading to an increase in traffic-generate air emissions.
Section 6.1 discusses the consequential minor traffic delays that would occur across
the proposal footprint caused as a result of implementing traffic management controls
at each work site during construction. Whilst the construction program and staging
would be used to ensure there would be no effect on the performance of the road
network overall, there would be a temporary minor effect on air quality within the
immediacy of the affected road corridor due to increased idling traffic. However, as
ambient conditions are significantly below the Air NEPM air quality goals this impact
would have no human health impact despite it potentially being perceptible.
Air quality impacts during operation
Appendix L shows the work sites where traffic flows would increase by more than
1,000 vehicles per day under the proposal. These changes would occur through the
reallocation and reprioritisation of traffic within the city centre as a result of
implementing the various projects under the Access Strategy. It would occur at
various points within the following work sites:
NW2: King Street
R1: Park Street
R2: Market Street
R4: Clarence Street
R5: York Street
S2: Goulburn Street
S3: Pitt Street
C1: Wentworth Avenue
C2: College Street
F1: Macquarie Street.
As the above screening criterion is triggered at ten of the 17 work sites there may be
a perceptible minor reduction in air quality within the immediate road corridor in these
locations. However, as described in the introduction to this section, there may
conversely be a perceptible minor improvement in air quality in other locations due to
the reduction in traffic on certain roads and its reallocation and reprioritisation onto
