Mount Morgan Mine Upper Mundic Gully TSF EA Amendment

additional controls are required or proposed. Minor quantity of non-regulated waste used during TSF construction may be generated including liners, concrete and fiberglass that will be disposed of in accordance with the Waste Hierarchy and the Heritage Minerals Waste Management Procedure. All waste transferred from the site will be transported by licensed waste transport carriers. Greenhouse Gas Assessment A Greenhouse Gas (GHG) Assessment has been prepared to provide supporting information to the Project EA Amendment Application under Section 226 of the Environmental Protection Act 1994 (EP Act). A copy of the full assessment is provided in Appendix L. The assessment has been conducted in accordance with the Greenhouse Gas Emissions Guidelines (DETSI, 2025) which outlines the requirements of a GHG assessment for an EA Amendment. These requirements and the respective sections where they have been addressed in this report (Appendix L) are shown in Table 63 . Table 63. DETSI Requirement 7.12

Application Requirement

Section of GHG Report

Description of the GHG emissions likely to be generated throughout the life of the project. Include an emissions inventory identifying the GHG to be emitted and the stage of the project at which the emissions will occur. Include a breakdown of GHG emissions by source that: Estimated the projected annual Scope 1 and Scope 2 CO2-e emissions over the life of the project. Include both unabated emissions and emissions after all avoidance and abatement measures have been accounted. Provides an estimate of annual Scope 3 emissions and total Scope 3 emissions over the life of the project Determine if the application meets the medium to high GHG emission category: • applications with expected GHG emissions (Scope 1 and Scope 2) 25,000 tonnes CO2-e or more per year (at any time during the life of the project) are considered medium to high emitters ; and • applications with expected GHG emissions (Scope 1 and Scope 2) of less than 25,000 tonnes CO2-e per year are considered low emitters. Identify the management practices proposed to be implemented to prevent or minimise adverse impacts. Proposed management practices should demonstrate that all reasonable and practical measures have been applied to manage GHG emissions through best practice design, process, technology, and management. Risk assessment that outlines the scale of expected GHG emissions from the activity and how they are expected to contribute to climate change impacts on Queensland’s environmental values Applications that are medium to high emitters must also develop and submit a GHG Abatement Plan.
