Mae Llywodraeth Cymru yn gefnogol iawn i’r ffordd wirfoddol o weithio, lle mae cymuned a allai fod yn lleoliad ar gyfer cyfleuster gwaredu yn ceisio cychwyn trafodaethau ynghylch gwneud hynny. Gallai trafodaethau o’r fath bara am ddeng mlynedd neu fwy a gall y gymuned dan sylw dynnu’n ôl ar unrhyw adeg. Ers 2008, o dan bolisi cyfredol Llywodraeth Cymru, mae wedi bod yn bosibl i gymuned yng Nghymru geisio trafodaethau o’r fath gyda Llywodraeth Cymru.
The Welsh Government strongly supports the voluntarist approach whereby a potential host community would seek to open discussions about hosting a disposal facility.  These discussions could last more than a decade during which a potential host community is able to withdraw at any time.  Since 2008 it has been possible for a community in Wales to seek to open such discussions with the Welsh Government under current Welsh Government policy.
