As previously announced, Alcoa of Australia Limited (Alcoa) has been working with relevant state government agencies to support Alcoa's annual mine approvals process for its mines in Western Australia.

In addition, a third party referred Alcoa's current and next rolling five-year plans to the Western Australian Environmental Protection Authority (EPA) for assessment under the WA Environmental Protection Act 1986 (the Act).

Alumina Limited (ASX:AWC) notes that the EPA today opened a public comment period on whether to conduct an environmental impact assessment into parts of Alcoa's current and next rolling five-year plans for its mines in WA. Following public consultation, the EPA will decide whether to conduct an assessment into parts of these mine plans - known as the 2022-2026 and 2023-2027 Mining and Management Programs (MMPs) - and, if so, at what level. There is no set timeframe for the EPA's determination. Given the uncertainty of an impending EPA assessment decision, if any, and the potential impacts on its mining and refining operations, Alcoa is currently unable to estimate the financial impact of a potential EPA assessment. Alcoa continues to mine lower grade bauxite at the Huntly mine in areas approved under the existing statutory approvals process to extend ore supply while it works through the approvals process. Further information on the EPA process can be found on its website (https://consultation.epa.wa.gov.au/seven-day-comment-on-referrals/bauxite-mining-darlingrange/). We note the statement today from Alcoa (attached).
