Slide 13: Visual Amenity
11 Visual Amenity • Moderate impacts in the short to medium term to the east until rehabilitation can be completed in nominally Year 2022 (Stage 2). • Approx 700m of the existing rehabilitated face of the emplacement area seen from approx. 2.6km to horizon Shearers Lane at Maison Dieu will be retain
Slide 14: Visual Amenity Mitigation
12 Visual Amenity Mitigation • The emplacement of overburden has been designed to the northern end of Cheshunt Pit to preserve the viewshed through to the Wollemi National Park. • The current setback distance from Maison Dieu is maintained Final landform behind (approx. 2.6km). ridgeline • Overburde

Slide 20: Visual Amenity Interactive Application
18 Visual Amenity Interactive Application Following the last HVO CCC, it was agreed to modify the HVO South flyover to show earlier stages plans rather than Stage 4 only.
Slide 21: Noise
19 Noise Noise and vibration study in accordance with NSW Industrial Noise Policy and Voluntary Land Acquisition and Mitigation Policy (VLAMP) • No additional properties are significantly impacted due to the proposed modification. • Ten properties along Jerrys Plains Road (all east of Jerrys Plains
Slide 22: Noise Mitigation
20 Noise Mitigation • HVO will progressively attenuate all the haul truck fleet to minimise noise impacts. • Continued operational management measures such as the relocation or shutting down of equipment during adverse weather conditions. • Haul roads to the proposed higher emplacement area to be co

Slide 24: Air Quality
22 Air Quality Air quality and greenhouse gas assessment in accordance with NSW Approved Method and Voluntary Land Acquisition and Mitigation Policy. • Similar air quality conditions modelled for Maison Dieu and Jerrys Plains as what is already approved for the existing operation. The proposal will
Slide 25: Air Quality Mitigation
23 Air Quality Mitigation Continued implementation of air quality management plan, including: • Use of water carts to manage wheel generated dust. • Altered or reduced operations in periods of high winds / elevated PM10. • Use of lower / more protected dumping locations during adverse conditions. •
Slide 26: Noise and Air Quality modelling
24 Noise and Air Quality modelling
Slide 27: Groundwater
25 Groundwater A groundwater assessment was undertaken against the Aquifer Interference Policy including a groundwater model peer reviewed by Dr Frans Kalf. • Groundwater take from Permian, alluvium and surface aquifers within previous predicted peak takes. • No private bores will be affected by >2m
Slide 28: Surface Water
26 Surface Water A surface water assessment determined: • No extension of State-approved disturbance footprint. • HVO South will not increase the cumulative impacts of salinity within the Hunter River due to continued participation in the HRSTS. • Any water taken from the Hunter River Regulated Wate
Slide 29: Ecology and Cultural Heritage
27 Ecology and Cultural Heritage • Proposal limited to within existing State-approved disturbance footprint. • No additional impacts to the ecology or heritage features.
Slide 30: Socio-economic
28 Socio-economic • Sustains mine employment at current levels and generates additional economic activity including $243 million in royalties and $160 million in taxes. • It does not result in social impacts arising from workforce influx, population change and associated impacts on infrastructure.
