Mine affected water (MAW) that has been treated in the Reverse Osmosis Water Treatment Plant (ROWTP) is authorised to be released to Environmental Dam 4 for controlled discharge to the receiving waters of Lagoon Creek when there is no natural flow on a continuous basis for a period of 18 months from when written notification is given to the administering authority*, subject to conditions

to C38 of this environmental authority. *NOTE: This notification relates to the initial commencement of ERA64 not the notification of the commencement of individual releases within this period as required by condition C29.

The release of treated MAW to waters must only take place in accordance with the criteria in Table C6- Treated MAW Release Criteria and Monitoring Point and subject to the contaminant release limits specified in Table C7- Treated MAW Release Limits.

The quality of contaminants released from the release point in Table C6- Treated MAW Release Criteria and Monitoring Points must be measured and recorded at the monitoring point and at the frequency specified in Table C6- Treated MAW Release Criteria and Monitoring Points.

The release of treated MAW to waters must not: (a) cause erosion to the bed and banks of the receiving waters; (b) cause a build-up of sediment in the receiving waters; (c) cause an adverse impact to aquatic biota; and (d) adversely impact on downstream water users.

Notification of Treated MAW Release Event The environmental authority holder must notify the administering authority as soon as practicable and no later than twenty-four (24) hours after commencing to release treated MAW to the receiving environment in accordance with condition C25. Notification must include the submission of written advice to the administering authority via WaTERS of the following information: (a) release commencement date/time; (b) expected release cessation date/time; (c) release point/s; (d) release volume (estimated); (e) receiving water/s including the natural flow rate; and (f) any details (including available data) regarding likely impacts on the receiving water(s).

Additional information for applicants Environmentally relevant activities The description of any environmentally relevant activity (ERA) for which an environmental authority (EA) is issued is a restatement of the ERA as defined by legislation at the time the EA is issued. Where there is any inconsistency between that description of an ERA and the conditions stated by an EA as to the scale, intensity or manner of carrying out an ERA, the conditions prevail to the extent of the inconsistency.

Environmental Authority EPML00335713 New Acland Coal Mine An EA authorises the carrying out of an ERA and does not authorise any environmental harm unless a condition stated by the EA specifically authorises environmental harm. A person carrying out an ERA must also be a registered suitable operator under the Environmental Protection Act 1994 (EP Act). Contaminated land It is a requirement of the EP Act that an owner or occupier of land give written notice to the administering authority if they become aware of the following: - the presence of, or happening of an event involving, a hazardous contaminant on the land that is causing, or is reasonably likely to cause, serious or material environmental harm (notice must be given within 24 hours); or - if the land is contaminated land - a change in the condition of the land that is causing, or is reasonably likely to cause, serious or material environmental harm (notice must be given within 24 hours); or - a notifiable activity (as defined in Schedule 3) having been carried out, or is being carried out, on the land (notice must be given within 20 business days). For further information, including the form for giving written notice, refer to the Queensland Government website www.qld.gov.au, using the search term `duty to notify'. Take effect Please note that, in accordance with section 200(1) of the EP Act, an EA has effect: (a) if the authority is for a prescribed ERA and it states that it takes effect on the day nominated by the holder of the authority in a written notice given to the administering authority--on the nominated day; or (b) if the authority states a day or an event for it to take effect--on the stated day or when the stated event happens; or (c) otherwise--on the day the authority is issued. However, in accordance with section 200(2) of the EP Act, the day that the EA takes effect may not be before: (a) if the authority is for a resource activity--the day the relevant tenure is granted to the applicant; or (b) if a development permit for a material change of use of premises under the Planning Act 2016 is necessary for carrying out an activity that related to the authority--the day the development permit takes effect; or (c) if an SDA Approval under the State Development and Public Works Organisation Act 1971 is necessary for carrying out an activity that relates to the authority--the day the approval takes effect. If this EA takes effect when the additional authorisation takes effect, you must provide the administering authority written notice within 5 business days of receiving notification of the related additional authorisation taking effect. The anniversary day of this environmental authority is the same day each year as the original take effect date unless you apply to change the anniversary day. The payment of the annual fee will be due each year on this day. An annual return will be due each year on 1 April. If you have incorrectly claimed that an additional authorisation is not required, carrying out the ERA without the additional authorisation is not legal and could result in your prosecution for providing false or misleading information or operating without a valid EA.
