CV = Critical Value. 2. AV = Adjustment Value. 3. bg = background noise level (LA90, adj, 15 mins) measured over 3-5 days at the nearest sensitive receptor. 4. To calculate noise limits in Table D1: If bg (CV - AV): Noise limit = bg + AV If (CV - AV) < bg CV: Noise limit = CV If bg > CV: Noise limit = bg + 0 5. In the event that measured bg (LA90, adj, 15 mins) is less than 30 dB(A), then 30 dB(A) can be substituted for the measured background level. 6. If the project is unable to meet the noise limits as calculated above alternative limits may be calculated using the processes outlined in the "Planning for Noise Control" guideline.

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. 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).

Permit OFFICIAL Environmental Authority EPVL00864413 Mobile and temporary activities If you operate a mobile and temporary ERA, other than regulated waste transport, you are required to maintain a work diary. You must: - keep the work diary records for 2 years after the last entry; - inform the administering authority within 7 days of the work diary being lost or stolen; - record the information required in the work diary for each location within 1 day of leaving the location.

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.

Permit OFFICIAL Environmental Authority EPVL00864413 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. 8 May 2026 Signature Date Giles Bezzina Enquiries: Delegate of the administering authority PO Box 7230, Cairns QLD 4870 Environmental Protection Act 1994 Phone: (07) 4222 5352 Email: ESCairns@detsi.qld.gov.au

CV = Critical Value. 2. AV = Adjustment Value. 3. bg = background noise level (LA90, adj, 15 mins) measured over 3-5 days at the nearest sensitive receptor. 4. To calculate noise limits in Table D1: If bg (CV - AV): Noise limit = bg + AV If (CV - AV) < bg CV: Noise limit = CV If bg > CV: Noise limit = bg + 0 5. In the event that measured bg (LA90, adj, 15 mins) is less than 30 dB(A), then 30 dB(A) can be substituted for the measured background level. 6. If the project is unable to meet the noise limits as calculated above alternative limits may be calculated using the processes outlined in the "Planning for Noise Control" guideline. Airblast overpressure nuisance D2 Blasting must: (a) Only be undertaken between 7am to 6pm; and (b) Not cause an exceedance of the limit for air blast overpressure or ground vibration peak particle velocity specified in Table D2 - Blasting noise limits at a sensitive place or commercial place.

OFFICIAL Permit Environmental Authority EPVL00864413 - sufficient knowledge and experience to certify that where the suitably qualified and experienced person has relied on advice and information provided by other persons with relevant expertise*: o they consider it reasonable to rely on that advice and information o the expert providing the advice and information has knowledge, competency, suitable experience and demonstrated expertise in the matters related to watercourse diversions. Persons with relevant expertise include: - Geomorphologist: person who has demonstrated competency and relevant experience in stream geomorphology and watercourse diversions. - Geotechnical Expert: person who has demonstrated competency and relevant experience in geotechnical assessment of soil characteristics suitable for watercourse diversions. - Vegetation Expert: person who has demonstrated competency and relevant experience in the identification, role and function of vegetation with watercourses and adjoining floodplains, and has demonstrated competency and relevant experience in revegetation of watercourse diversions and adjoining floodplains. - Groundwater Expert: person who has demonstrated competency and relevant experience in groundwater systems. - Surface Water Expert: person who has demonstrated competency and relevant experience in hydrology. - Engineer: person who is a Registered Professional Engineer of Queensland (RPEQ) under the provisions of the Professional Persons Act 2002 or has similar qualifications under a respected professional registration association, and has demonstrated competency and relevant experience in design and construction of watercourse diversions. - Soils Expert: person who has demonstrated competency and relevant experience in soil classification including the physical, chemical and hydrologic analysis of soil. System design plan means a plan that manages an integrated containment system that shares the required DSA and/or ESS volume across the integrated containment system. Temporary watercourse diversion is a man-made structure that may incorporate geomorphologic, hydraulic, hydrologic and ecological components of a local watercourse and is designed, constructed, operated and maintained to an engineering standard that ensures the diversion does not compromise the equilibrium and performance of the diversion and adjoining watercourses. A temporary diversion is replaced by a permanent diversion, or the re- establishment of the pre-existing watercourse, within the timeframe specified in the design plan. the Act means the Environmental Protection Act 1994. Void means any constructed, open excavation in the ground. Water is defined under Schedule 4 of the Water Act 2000. Watercourse has the meaning in Schedule 4 of the Environmental Protection Act 1994 and means a river, creek or stream in which water flows permanently or intermittently-- (a) in a natural channel, whether artificially improved or not; or (b) in an artificial channel that has changed the course of the watercourse. Watercourse includes the bed and banks and any other element of a river, creek or stream confining or containing water. Water quality means the chemical, physical and biological condition of water.

OFFICIAL Permit Environmental Authority EPVL00864413 Waters includes all or any part of a river, stream, lake, lagoon, pond, swamp, wetland, unconfined surface water, unconfined water in natural or artificial watercourses, bed and banks of a watercourse, dams, non-tidal or tidal waters (including the sea), stormwater channel, stormwater drain, roadside gutter, stormwater run-off, and groundwater. Wet season means the time of year, covering one or more months, when most of the average annual rainfall in a region occurs. For the purposes of DSA determination this time of year is deemed to extend from 1 November in one year to 31 May in the following year inclusive. END OF SCHEDULE H
