it has been suggested that between 100 ,000 and 500 ,000 tonnes of sand could be extracted from these sites annually
awgrymwyd y gallai rhwng 100 ,000 a 500 ,000 o dunelli o dywod gael eu hechdynnu o'r safleoedd hyn bob blwyddyn
powys county council stated in its draft unitary development plan , that it does not want to highlight areas where gravel could be extracted
nododd cyngor sir powys yn ei gynllun datblygu unedol drafft , nad yw am amlygu ardaloedd lle y gellid echdynnu gro
i recognise that the supply of sand and gravel is a difficult issue because so many people want to use it , but do not want it to be extracted close to their own homes
cydnabyddaf fod cyflenwi tywod a graean yn fater anodd oherwydd mae cymaint o bobl am eu defnyddio ond nid ydynt am iddynt gael eu cloddio ger eu cartrefi
what we are saying is that development should never occur in such a way that those resources cannot be extracted , because we cannot predict whether there will be a national emergency in future
yr hyn a ddywedwn yw na ddylai datblygiad fyth ddigwydd mewn ffordd sy'n golygu na ellir cloddio'r adnoddau hynny , gan na allwn ragweld pa un a fydd argyfwng cenedlaethol yn y dyfodol ai peidio
every one of those proposals is controversial , and all campaigners will quote the fact that , under the principle of sustainable development , gravel should not be extracted from the site that they wish to protect
mae pob un o'r cynigion hynny'n ddadleuol , a bydd pob ymgyrchwr yn cyfeirio at y ffaith na ddylid codi graean o'r safle y mae'n dymuno ei amddiffyn , yn unol ag egwyddor datblygu cynaliadwy
in the following paragraph , you mention the existing regional technical group that will work with relevant local authorities to see where land-based sand and gravel could be extracted to cause the least environmental impact
yn y paragraffau dilynol , soniwch am y grŵp technegol rhanbarthol sy'n bodoli ar hyn o bryd a fydd yn gweithio gydag awdurdodau lleol perthnasol i weld ymhle y gallai tywod a graean gael eu cloddio i achosi'r effaith amgylcheddol leiaf
william graham : i am sure that you will join me in agreeing with the british dental association that it is tragic that , even in 2003 , there are still children as young as five having most or all of their teeth extracted under general anaesthetic as a result of tooth decay
william graham : yr wyf yn siwr yr ymunwch â mi i gytuno â chymdeithas ddeintyddol prydain ei bod yn drychineb bod plant mor ifanc â phum mlwydd oed , hyd yn oed yn 2003 , yn cael triniaeth i dynnu'r rhan fwyaf neu'r cyfan o'u dannedd o dan anesthetig cyffredinol o ganlyniad i bydredd dannedd
i have also been informed by experts , such as professor ron bridle from cardiff university's school of engineering , that the sand that could be extracted from the valley area is likely to be coarser and of a poorer quality , and therefore of less use to the building industry , than the sand that comes from the ocean -- it depends upon the amount of movement and rubbing of particles that takes place
yr wyf hefyd wedi'm hysbysu gan arbenigwyr , yr athro ron bridle o goleg peirianneg prifysgol caerdydd yn eu plith , bod y tywod y gellid ei echdynnu o ardal y dyffryn yn debygol o fod yn frasach ac o ansawdd salach , ac felly byddai'n llai defnyddiol i'r diwydiant adeiladu , na'r tywod a ddaw o'r môr -- mae'n dibynnu ar nifer y symudiadau a'r gronynnau yn rhwbio yn erbyn ei gilydd
