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). Contaminated land It is a requirement of the EP Act that an owner or occupier of contaminated land give written notice to the administering authority if they become aware of the following: - the happening of an event involving a hazardous contaminant on the contaminated land (notice must be given within 24 hours); or - a change in the condition of the contaminated land (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 contaminated land (notice must be given within 20 business days) that is causing, or is reasonably likely to cause, serious or material environmental harm. 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 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.

   Permit Environmental authority EPML01722313 However, if the EA is authorising an activity that requires an additional authorisation (a relevant tenure for a resource activity, a development permit under the Planning Act 2016 or an SDA Approval under the State Development and Public Works Organisation Act 1971), this EA will not take effect until the additional authorisation has taken 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 effective date. The payment of the annual fee will be due each year on this day. An annual return will be due each year on 01 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 environmental authority.

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 5. bg = background noise level (LA90, adj, 15 mins) measured over 3-5 days at the nearest sensitive receptor 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.

"Design Plan" is a document that contains the design, operation, monitoring and revegetation criteria of a watercourse diversion that addresses the outcomes stated in the model conditions and any conditions on the environmental authority relating to the diversion. The document should include, but not be limited to: - required information under a functional design - the location, function and description of geomorphic and riparian vegetation features within the proposed watercourse diversion - results from hydrologic, hydraulic and sediment transportation modelling used in the design of the diversion - a revegetation and vegetation management plan (a revegetation plan) for the diversion

    Permit Environmental authority EPML01722313 - engineering drawings depicting the physical attributes and dimensions of the diversion - (if relevant) the staged development of a permanent watercourse diversion including the proposed use of temporary watercourse diversions with identified lifespans - all investigation and other reports relied on by the design; and - plans and specifications sufficient to complete construction and revegetation in accordance with the design. "Environmental Authority (EA)" is defined under Schedule 4 of the Environmental Protection Act 1994. "Equilibrium": A state where `balance' is achieved despite changing variables. "Functional Design" is a document that contains `conceptual' information about the design, operation and revegetation criteria of a watercourse diversion that addresses the outcomes stated in the model conditions and any conditions on the environmental authority relating to the diversion. The document should include, but not be limited to: - geomorphic and vegetation assessment of the existing watercourse - hydrologic conditions of the existing watercourse - the proposed watercourse diversion route - results from hydrologic, hydraulic and sediment transportation modelling used in the design of the diversion. "Functionality": The purpose that something is designed or expected to fulfil. "Holder", for a mining tenement, means a holder of the tenement under the Mineral Resources Act 1989, and the holder of the associated environmental authority under the Environmental Protection Act 1994 "Minimise" is to reduce to the smallest possible amount or degree. "Permanent Watercourse Diversion" is a man-made structure that incorporates the geomorphologic, hydraulic, hydrologic and ecological components of a local watercourse and is designed, constructed, operated and maintained according to an engineering standard that ultimately achieves a self-sustaining watercourse able to function without features or characteristics that rely on ongoing maintenance or that impose a financial or other burden on the proponent, government or the community. "Pre-existing watercourse" is the section of watercourse from which the flow of water will be diverted as a result of the construction and operation of a watercourse diversion. "Revegetation" is the re-establishment of vegetation1 of a species and density of cover similar to surrounding undisturbed areas or the landform that existed before mining activities on soil surfaces associated with the construction or rehabilitation of a watercourse diversion. "Self-sustaining" means not requiring on-going intervention and maintenance to maintain functional riverine processes and characteristics "Suitably qualified and experienced person" means a person who is a Registered Professional Engineer of Queensland under the provisions of the Professional Engineers Act 2002, who has an appropriate level of expertise in the structures, geomechanics, hydrology, hydraulics and environmental impact of watercourse diversions. An appropriate level of expertise includes: - demonstrable competency, experience and expertise in- - investigation, design or construction of watercourses diversions - operation and maintenance of watercourse diversions - geomechanics with particular emphasis on channel equilibrium, geology and geochemistry - hydrology with particular reference to flooding, estimation of extreme storms, water management or meteorology - hydraulics with particular reference to sediment transport and deposition and erosion control

"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. "Water" is defined under Schedule 4 of the Water Act 2000. "Watercourse" is defined under sections 5 and 5A of the Water Act 2000. "Watercourse Diversion" is a man-made structure that diverts or interferes with the course of flow within a watercourse, but that does not impound water.
