Attachment C – Project Description

J17188 | RP84 | v 1 2

A total of 33 submissions were received during the public exhibition period of the EIS for the proposed segment factory, including 26 submissions from the community, six from NSW government agencies and one from Snowy Monaro Regional Council (SMRC). Of the 26 community submissions, 22 related to Snowy 2.0 Main Works rather than the proposed segment factory. Accordingly, while the submissions on Main Works are recognised in this RTS, the matters raised in the submissions will be addressed in the RTS for Main Works. A detailed analysis of matters raised in the submissions is set out in Chapter 2.

1.2.2 Commonwealth

On 26 June 2019, Snowy Hydro referred the proposed segment factory to the Commonwealth Minister for the Environment under the provisions of the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). On 13 August 2019, the proposed segment factory was determined by the Acting Assistant Secretary Assessments and Waste Branch of the Commonwealth Department of the Environment and Energy (DEE), as delegate to the Minister, to be ‘not a controlled action’ and therefore does not require further assessment or approval under the EPBC Act.

1.3 The proposed segment factory

1.3.1 Key elements of the exhibited project

The site of the proposed segment factory is located on land in the southern eastern corner of the Polo Flat industrial area. The site, which has an area of about 31.6 hectares (ha), is surrounded by industrial development to the north and west and predominantly vacant land to the south and east. Notwithstanding this, an abattoir is located immediately of the east of the site. A photograph of the site and surrounding development can be seen in Photograph 1.1.

Photograph 1.1 The site as viewed from the west – the site is located behind the industrial development located in the middle-ground of the photograph

J17188 | RP84 | v 1 3

In developing the layout and design of the proposed segment factory, an iterative and risk-based design and assessment process was adopted, referred to as a design integration and assessment approach (DIAA). This DIAA process was undertaken with the guiding principles of avoiding and minimising environmental impacts where possible. While project components are generally fixed, there may be some refinements to the physical layout or design of certain components of the project following further investigation and design. Consistent with the DIAA process, the objective for the detailed design process is to optimise the design to meet construction requirements while continuing to minimise environmental impacts.

The proposed segment factory would contain a concrete batching plant (CBP), building for the manufacture of the segments (the precast building), uncovered storage areas for raw material and segments, vehicle parking areas and associated offices and workshops. The layout of the proposed segment factory can be seen in Figure 1.1.

The construction phase of the proposed segment factory would last about five months utilising a workforce of about 30 people. Construction vehicle movements would comprise construction workers’ light vehicles as well as heavy vehicles transporting equipment, building and construction materials, waste, and fill material if required.

The proposed segment factory would operate over a period of about 3.5 years utilising a workforce of about 125 people.

Approximately 130,500 segments making up about 14,500 precast concrete tunnel rings would be manufactured over the operational period of the proposed segment factory for exclusive use as part of Snowy 2.0. Each tunnel ring would consist of nine segments.

Primary inputs for the proposed segment factory include aggregate, sand, cement and rebar steel. Primary outputs include the precast tunnel segmental linings which would be transported to the construction sites of Snowy 2.0 within KNP.

Operational vehicle movements will comprise light vehicles (worker’s vehicles and service vehicles) and heavy vehicles required for the transportation of the main inputs for the segments and for the transportation of the segments.

1.3.2 Refinements since public exhibition

Since exhibition of the EIS for the proposed segment factory there have been some refinements to the project, including:

• reduction in predicted traffic generated by the proposed segment factory;

• resolution on external road upgrades required for the proposed segment factory and Snowy 2.0 Main Works;

• update to the layout provided in the EIS of the proposed segment factory to reflect noise modelling reported within the EIS; and

• clarification around need for further soil testing for site re-use, following decontamination.

These refinements form part of the DIAA process identified above.

Details on these refinements are provided in Chapter 3.
