Environment
Talison Lithium is committed to sustainable development and regards the environmental management and rehabilitation of mining sites as among its highest priorities. The Company continuously reviews and improves its environmental management system to reduce the impact of mining on site and on neighbouring communities.
The Greenbushes Lithium Operation has stringent environmental operating conditions. The site is certified to International Standards ISO 9001:2008 Quality Management System Requirements and ISO 14001:2014 Environmental Management System requirements by BVQI and is externally audited.
Talison Lithium’s key environmental responsibilities at the Greenbushes Lithium Operations include:
Rehabilitation of mined land to re-establish a self-sustaining, native forest ecosystem
Ensuring the quality of local water resources are maintained
Minimising the spread of weeds on site in accordance with an Integrated Weed Management Plan
Waste minimisation, employing a policy of reduce, reuse and recycle wherever possible
Environmental monitoring in accordance with the Company’s operating licence
Providing Offset habitat to replace any habitat impacted by the mine’s operations.

Approvals
Greenbushes Lithium Mine Expansion EPBC 2018/8206 MS1111
The Greenbushes Lithium Mine Expansion was formally referred to the Commonwealth Department of the Environment and Energy (DotEE) on 9 May 2018 (EPBC reference: 2018/8206) for assessment under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) on potential impact on threatened species and communities which listed as Matters of National Environmental Significance (MNES). On 17 June 2018, the DotEE determined the Proposal is a Controlled Action and required formal assessment and a decision on approval under the EPBC Act. The DotEE advised on 19 August 2018 that under section 87 of the EPBC Act the Proposal would be assessed by an accredited assessment with the WA Government. The Expansion also required assessment under the Environmental Protection Act Part IV Environmental Impact Assessment Process which through the accredited process which was referred to the Environmental Protection Authority, June 2018 . On the 19th August 2019 Ministerial Statement No. 1111 EP Act 1986 (WA) was published for the expansion, outlining that pursuant to section 45 of the Environmental Protection Act 1986 subject to implementation conditions and procedures the proposal may be implemented. On the 14th November 2019 in accordance with Part 9 of the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), Talison Lithium Australia Pty Ltd was granted approval to clear native vegetation to construct and operate an expansion of the Greenbushes mine in accordance with the conditions specified in the approval (EPBC 2018/8206).
Talison Lithium provides an annual monitoring report to the Department of Water and Environmental Regulation (DWER), which includes an Annual Audit Compliance Report (AACR) that is published on the DWER website. The AACR includes a summary of total production and waste figures, as well as a summary of non compliances and resultant corrective actions. See below a link to the official document.

REHABILITATION
Rehabilitation involves initial earthworks to reform the landscape, application of a 'topsoil' layer (usually soft rock or lateritic clay), followed by ripping and contouring to improve drainage and promote root growth. Available rocks, logs or forest litter are spread to provide habitat for local fauna.
Talison has a programme of progressive rehabilitation of waste rock landform and tailings storage facilities which is scheduled to coincide with available rehabilitation materials and equipment. Progressive rehabilitation has significant benefits which include early establishment of vegetation, which reduces dust levels and improves visual surroundings.
The overall objective of Talison’s rehabilitation programme is to establish a self sustaining healthy community with selected attributes compatible with surrounding forest, and landforms that blend with the mine’s undulating scarp location. To assist in this process seeds are collected during late Spring typically from a site within a 15 kilometre radius of the Greenbushes Lithium Operations. Seeding of rehabilitation areas is carried out in early Winter followed by planting of jarrah and marri seedlings. Weed control is an important component of rehabilitation during the first three years. The success of rehabilitation is monitored annual by assessing plant density and species variety.
The success of rehabilitation efforts at the Greenbushes Lithium Operations received recognition in 2006 when the Company was awarded a “Golden Gecko”. This award promotes and recognises outstanding environmental achievement in the Western Australian resources industry.
Talison Lithium partnered with local Blackwood Basin Group to create a wetland haven for wading birds at Schwenke’s Dam, an historic mining void created from tin and tantalum production in the 1950s and 1960s. The four- year project, completed in 2017, has resulted in the creation of a wetland habitat with low key recreational facilities for the community including walk trails, boardwalk and interpretive signage.
EXPANSION OF MINE WASTE ROCK LANDFORM
GREENBUSHES WESTERN AUSTRALIA (EPBC 2013/6904)
OFFSETS FOR MATTERS OF NATIONAL SIGNIFICANCE (75.7 HA 2016 APPROVAL
In 2013,as part of Talison Lithium’s continued operations, approval was sought to expand the Waste Rock Landform resulting in the loss of 75.7 ha of habitat for threatened species. This action, under the Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act) was considered a controlled action specifically and Talison Lithium was requested to consider impacts of the proposal on the following Matters of National Significance (MNES):
Forest Red-tailed Black Cockatoo (Calyptorhynchus banksii naso) Vulnerable;
Baudin’s Black Cockatoo (Calyptorhynchus Baudinii) Endangered; and
Carnaby’s Black Cockatoo (Calyptorhynchus latirostris) Endangered.
Under the EPBC Act a habitat Offset is required to compensate for any loss of habitat that impacts (MNES). In 2016 an agreement was reached between Talison Lithium and a South-West grazing company which currently holds 121.7 ha of Black Cockatoo habitat which is under threat. Under the agreement a perpetual restrictive covenant has been placed on the 121.7 ha which will require the area to be maintained and managed for its value as native vegetation with improvement of its assessed habitat score from 7/10 to 8/10 over a 20 year period.
An Offsets Management Plan has been developed for this habitat and will be managed on behalf of Talison Lithium by the Blackwood Basin Group. The progress of the Offsets block will be reported and published annually. Links to the management plan and annual and reports can be found below.
WATER MANAGEMENT
The Greenbushes Lithium Operations is located in the Blackwood Valley Catchment. Water for mineral processing is sourced from rainfall and stored in several process water dams and mining voids located on the site. Conservation of water is a high priority and process water is recovered and recycled. To ensure that surface water quality is maintained, measurement and reporting of water quality parameters in key water bodies is carried out on a weekly basis. Ground water monitor bores are located around the process plants and tailing dams and are monitored on a quarterly basis.
During the mining processes of blasting, crushing and grinding of ore, naturally occurring elements such as lithium minerals are liberated into the water. Talison is constructing a Water Treatment Facility to remove these elements before re-use (recycling) or discharge.
