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'.

OFFICIAL Permit Environmental authority EPML00658113 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 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 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. 27 May 2025 Signature Date Teale Gibbs Enquiries: Tourism, Science and Innovation PO Box 7230, CAIRNS QLD 4870 Delegate of the administering authority Phone: (07) 4222 5352 Environmental Protection Act 1994 Email: ESCairns@des.qld.gov.au Privacy statement Pursuant to section 540 of the EP Act, the Department is required to maintain a register of certain documents and information authorised under the EP Act.

That is, the instantaneous maximum volume within the walls, without regard to flows entering or leaving (e.g. via spillway). Design plan is a document setting out how all identified consequence scenarios are addressed in the planned design and operation of a regulated structure. Design storage allowance or DSA means an available volume, estimated in accordance with the Manual for the administering authority, must be provided in a dam as at 1 November each year in order to prevent a discharge from that dam to an annual exceedence probability (AEP) specified in that Manual.
