Rydym wedi ymrwymo i ymchwilio a threialu technoleg, er mwyn sicrhau y gall atebion technegol priodol gefnogi'r gwaith o fonitro tomenni glo yn y tymor hwy.  Yn gynharach eleni, rhoddodd Llywodraeth Cymru arian i gefnogi awdurdodau lleol i brynu dronau i'w defnyddio fel rhan o'u trefn arolygu a rheoli.
We are committed to researching and trialling technology, to ensure appropriate technical solutions can support the longer term monitoring of coal tips.  Earlier this year, Welsh Government provided funding to support local authorities with purchasing drones to use as part of their inspection and management regime.
