Subject: Planning
Part of speech: Noun, Feminine, Singular

Notes: Term at ddibenion trwyddedu petrolewm yn unig. Defnyddir 'tua thir Cymru' gan fod y ffurf "landward" yn gyfystyr ac yn cael ei defnyddio mewn deddfwriaeth Saesneg berthnasol. Hefyd, bydd peth o'r ardal hon yn gyfan gwbl dan ddŵr môr drwy'r amser. Gweler hefyd internal waters / dyfroedd mewnol.
