Proposed Action
Bloomfield Collieries Pty Limited (Bloomfield) owns and operates Rix’s Creek Mine (RCM) located in the Hunter Valley of New South Wales (NSW). RCM is a coal mining operation located approximately 5 km north of Singleton at its closest point and both east and west of the New England Highway (NEH) (see Figure 1 within Attachment A - Figures). RCM is the collective name for Rix’s Creek North (RCN) (previously Integra Open Cut) and Rix’s Creek South (RCS) (the original Rix’s Creek Mine).
Bloomfield is seeking a new State Significant Development Consent to facilitate the continuation of open cut mining operations at RCN.
The proposed action is part of the RCN Continuation Project (the Project). The conceptual layout of the Project is shown in Figure 1 within Attachment A - Figures and entails the continuation of mining operations primarily within the existing mining authorities held for RCN.
The Project is generally comprised of the following key elements:
- The relocation of an approximate 4 kilometre (km) section of the NEH to the west, including Bloomfield removing and accepting some material associated with the formation of the new road alignment at Rix’s Creek South (RCS);
- The westerly advancement of the operations within the Camberwell Pit mining through the current NEH alignment;
- The advancement of mining to the north and west of the Falbrook Pit out to Middle Falbrook and Stoney Creek Roads;
- Maintain the overall combined peak Run of Mine (ROM) extraction rate of 6 Million tonnes per annum (Mtpa) at RCN:
- Falbrook Pit to reach 3.3 Mtpa (from the currently approved 1.5 Mtpa); and
- Camberwell Pit to reach 4.5 Mtpa (as currently approved);
- A revised final landform, including changes to the number, location and volumes of the final voids;
- Ability to mine 24/7 in all areas, including in the Falbrook Pit (currently approved between 7 am and 10 pm);
- Ability to take overburden from RCN to RCS which will assist in improving rehabilitation outcomes;
- The extension of mine life from that currently approved for RCN (i.e. end 2035) by approximately 14 years until the end of 2049.
Some of the mining activities associated with the Project will be within the approved project disturbance boundary for the State Approved Mining Operations for RCN (i.e. areas approved to be disturbed for topsoil stockpiles, water management and other purposes). The western extents of the Camberwell Pit Mining Area and the Falbrook Pit Mining Area will require additional disturbance of native vegetation beyond the area currently approved for disturbance for RCN.
The realignment of the NEH is the only construction works required for the Project and will require additional disturbance to the west of the Camberwell Pit Mining Area.
The proposed action that is subject to this Referral consists only of the aspects of the Project that are not part of the State Approved Mining Operations at RCN and those aspects that have the potential to impact upon matters of Matters of National Environmental Significance (MNES). This includes the mining activities located within the proposed action area as illustrated on Figure 1 within Attachment A - Figures. The proposed action area covers approximately 537 ha of which around 71% (381 ha) is located outside of the State Approved RCN disturbance boundary.
The final disturbance boundary for the proposed action within this proposed action area will include the following disturbance activities:
- Realignment of the NEH;
- Advancement of the Camberwell Pit to the west through the current NEH alignment;
- Advancements of the Falbrook Pit to the north and west out to Middle Falbrook and Stoney Creek Roads; and
- Water management infrastructure associated with the NEH alignment and the proposed mining operations.
The realignment of the NEH and the advancements of the existing open cut mining areas will require the clearing of native vegetation that has not previously been approved for disturbance. This may have an impact on the local plant community types or habitat for fauna species.
The disturbance associated with the NEH realignment and the open cut mining activities proposed by the Project also has the potential to result in impacts to surface water catchments and regional groundwater resources.
The Project will facilitate the recovery of a coal resource to the west of existing State Approved Mining operations within the Camberwell Pit and to the north west of the State Approved Mining Operations within the Falbrook Pit. This includes allowing the recovery of coal within the approved mining area in the western portion of the Camberwell Pit which is currently unable to be recovered due to geotechnical considerations. The relocation of the NEH further to the west will enable the recovery of the coal resources which occur within the existing RCN mining authorisations.
The proposed action will prolong the life of State Approved Mining Operations at RCN by approximately 14 years (until the end of 2049) and facilitate the optimal recovery of coal resources within the existing mining authorities held by Bloomfield. The Project will continue to play an integral role in servicing the needs of the export coal markets as volumes of export quality coal begins to decline in the Hunter Valley.
The existing social and economic benefits of the RCM operations will continue for a further nine years (noting that RCS holds approval for mining until the end of 2040) as a result of the extended mine life for the Project. The Project will enable the ongoing annual expenditure of approximately $170 Million in goods and services and the employment of approximately 325 Full Time Equivalent employees, while supporting approximately 520 individual suppliers.
