Permit Environmental authority - EPML04041216 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). Mobile and temporary activities If you operate a mobile and temporary environmentally relevant activity (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. 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 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, 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.

Permit Environmental authority - EPML04041216 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.

'environmental authority', an environmental authority issued under section 195 that approves an environmentally relevant activity applied for in an application. 'environmental authority holder', means the holder of an environmental authority issued under section 195 that approves an environmentally relevant activity applied for in an application and any others works conducted by an entity on the approved leases under the environmental authority. 'environmental nuisance' as defined in section 15 of the EP Act. 'groundwater monitoring program', means the holder of the environmental authority must appropriately monitor the potential impacts to groundwater and develop a suitable plan or program that achieves this requirement. '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. 'infrastructure' means water storage dams, levees,, roads and tracks, buildings and other structures built for the purpose of the mining activity. 'land' in the 'land schedule' of this document means land excluding waters and the atmosphere, that is, the term has a different meaning from the term as defined in the Environmental Protection Act 1994. For the purposes of the Acts Interpretation Act 1954, it is expressly noted that the term 'land' in this environmental authority relates to physical land and not to interests in land. 'land use' --means the selected post mining use of the land, which is planned to occur after the cessation of mining operations. 'm' means metres. 'measures' includes any measures to prevent or minimise environmental impacts of the mining activity such as bunds, silt fences, diversion drains, capping, and containment systems. 'minimise' is to reduce to the smallest possible amount or degree. 'mining activities' is an activity that is an authorised activity for a mining tenement under the Mineral Resources Act 1989. For the purpose of this EA it refers to ERA 20(b) - Dimension stone mining, involving mining a quantity of material of at least 100,000t but not more than 1,000,000t in a year. 'non-polluting' means having no adverse impacts upon the receiving environment. 'offensive' means causing offence or displeasure; is disagreeable to the sense; disgusting; nauseous or repulsive. 'protected area' means -- a protected area under the Nature Conservation Act 1992, or a) a marine park under the Marine Parks Act 1992, or b) a World Heritage Area. 'receiving environment' in relation to an activity that causes or may cause environmental harm, means the part of the environment to which the harm is, or may be, caused. The receiving environment includes (but is not limited to): c) a watercourse d) groundwater 'receiving waters' means the waters into which this environmental authority authorises releases of mine affected water. 'rehabilitation' the process of reshaping and revegetating land to restore it to a stable landform. 'release' of a contaminant includes: a) to deposit, discharge, emit or disturb the contaminant; and b) to cause or allow the contaminant to be deposited, discharge, emitted or disturbed; and c) to allow the contaminant to escape; and

Permit Environmental authority - EPML04041216 d) to fail to prevent the contaminant from escaping. '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. Note 1: Not including a species declared under the Land Protection (Pest and Stock Route Management) Regulation 2003 as a category class 1 pest, category class 2 pest or category class 3 pest. 'self-sustaining' means not requiring on-going intervention and maintenance to maintain functional riverine processes and characteristics 'sensitive place' means: a) a dwelling, residential allotment, mobile home or caravan park, residential marina or other residential premises, or b) a motel, hotel or hostel, or c) an educational institution, or d) a medical centre or hospital, or e) a protected area under the Nature Conservation Act 1992, the Marine Parks Act 1992 or a World f) Heritage Area, or g) a public park or gardens. Note: The definition of 'sensitive place' and 'commercial place' is based on Schedule 1 of EPP Noise. That is, a sensitive place is inside or outside on a dwelling, library and educational institution, childcare or kindergarten, school or playground, hospital, surgery or other medical institution, commercial & retail activity, protected area or an area identified under a conservation plan under Nature Conservation Act 1992 as a critical habitat or an area of major interest, marine park under Marine Parks Act 2004, park or garden that is outside of the mining lease and open to the public for the use other than for sport or organised entertainment. A commercial place is inside or outside a commercial or retail activity. A mining camp (i.e., accommodation and ancillary facilities for mine employees or contractors or both, associated with the mine the subject of the environmental authority) is not a sensitive place for that mine or mining project, whether or not the mining camp is located within a mining tenement that is part of the mining project the subject of the environmental authority. For example, the mining camp might be located on neighbouring land owned or leased by the same company as one of the holders of the environmental authority for the mining project, or a related company. Accommodation for mine employees or contractors is a sensitive place if the land is held by a mining company or related company, and if occupation is restricted to the employees, contractors and their families for the particular mine or mines which are held by the same company or a related company. For example, a township (occupied by the mine employees, contractors and their families for multiple mines that are held by different companies) would be a sensitive place, even if part or all of the township is constructed on land owned by one or more of the companies. 'static screens' means any rock screen, rock separator, aggregate separator or similar devices that do not utilise any mechanical screening methods.
