The Environmental Impact Assessment (EIA) Report for Lynas to build a landfill to store its neutralisation underflow (NUF) residue has been approved by the Department of Environment (DOE) with 68 conditions.

In an email to Malaysiakini, the DOE said these conditions include limiting the NUF secure landfill to a height of 30m from ground level, excluding its "capping", which is approximately the height of a nine-storey building.
