["RM3","Remediation of Contaminated Land (Waste Rock Material Treatment) ","a) Site added to the Environmental Management Register, if required. \nb) Remediation of contaminated soil materials such as hydrocarbon has been undertaken as required. \nc) Validation testing confirms that contaminated soils have been removed or remediated. \nd) \tNo acid rock drainage is occurring or has the potential to occur. Acid rock drainage would be measured against the thresholds detailed in the Global Acid Rock Drainage Guide (INAP, 2009).\n\n\n"]

Backfilled emplacement areas would follow the same landform design criteria to be considered geotechnically stable. \ng) Infrastructure area slope angles do not exceed 5%. For slopes over 2%, continuous slope length does not exceed 70 m.  \nh) Slopes of >16% have been treated with rock mulch to assist with maintaining slope stability.\ni) Installation of contour or graded drains as per construction design which has been certified by an appropriately qualified person. \nj) Final voids certified by a suitably qualified and experienced person as geotechnically stable.\nk) Final landform is stable and has been certified by an appropriately qualified person. \nl) Engineering report on completed cover finalised, certifying that the capping system has been built/installed as per engineering design plan.\nm) Overburden is classified as NAF and is placed in any in-pit or ex-pit spoil dump.\nn) Interburden is preferentially placed in-pit to provide the acid neutralisation capacity for spot-dumping of Potentially Acid Forming (PAF) materials and creation of Permian caps and bunds on coal reject cells.\no) PAF floor materials from the Middlemount seam should remain in the open pit and be covered with NAF spoil.\np) Burial of PAF be lime dosed (at a rate of 10 t/ha or as confirmed by field trials) and kept at least 10 m away from the outer surfaces of final landforms by covering with Permian spoil.\nq) Consideration of leaching potential via leaching tests for PAF materials\nr) the maximum ratio of PAF coarse reject/tailings to Permian spoil at the out-of-pit spoil emplacement area be 1 to 10. \n\n"]
