A REMP must be developed and implemented to monitor and record the effects of the release of contaminants in the receiving environment periodically and whilst contaminants are being discharged from the site, with the aims of identifying and describing the extent of any adverse impacts to local environmental values, and monitoring any changes in the receiving water. A copy of the REMP must be provided to the administering authority prior to its implementation and due consideration given to any comments made on the REMP by the administering authority. For the purposes of the REMP, the receiving environment is all underlying groundwaters, the waters of Maggies Creek, Gin Creek, the Mort River and any connected waterways that are downstream of a release point/s listed in Schedule C - Table C1 (Contaminant Release Points) of this environmental authority.

Reference sites must comply with the following criteria: (i) be from the same bio-geographic and climatic region; (ii) have similar geology, soil types and topography; (iii) contain a range of habitats similar to those at the potentially impacted sites; Permit Environmental Authority EPML00701913 (iv) have a similar flow regime; and (v) not be so close to the potentially impacted sites that any disturbance at the potentially (vi) impacted sites also results in a change at the reference site; (k) The frequency or scheduling or sampling and analysis sufficient to determine water quality objectives and to derive site specific reference values within 3 years (depending on wet season flows) in accordance with the latest edition of the Administering Authority's Queensland Water Quality Guidelines. For ephemeral streams, this should include periods of flow irrespective of mine or other discharges; (l) Specify sampling and analysis methods and quality assurance and control; (m) Any historical datasets to be relied upon; (n) Description of the statistical basis on which conclusions are drawn; and (o) Any spatial and temporal controls to exclude potential confounding factors.

General waste, other than those waste items mentioned in condition (G3), must only be disposed of into
- G5
the waste disposal trench facility located on ML2693 and identified in Schedule J - Plan 8 (General Waste
- G6
Disposal Area). The active waste disposal trench must be constructed and operated to minimise the generation of leachate, including a system of diversion drains or embankments to divert surface waters away from any area where contact with wastes or sources of contamination may occur. Unless otherwise permitted by the conditions of this environmental authority, waste generated on-site must Permit Environmental Authority EPML00701913 not be burnt on-site, except for cardboard and timber for safety exercises only, no waste may be taken off- site and burnt. Regulated Waste
- G7
Regulated waste, other than that authorised to be disposed of on site under this authority, must only be removed and transported from the site by a person who holds a current authority to transport such wastes to a facility that is lawfully able to accept the waste under the Environmental Protection Act 1994. Tyre Storage and Disposal
- G8
Subject to demonstrating to the administering authority that no other use higher in the waste management hierarchy can be practicably implemented, waste tyres generated from mining activities may be disposed of on site in non-acid forming waste rock dumps or underground stopes. Waste Rock Management
