techiaith/bydtermcymru-tm-en-cy huggingface dataset:
English: Examples of data collection can include traffic surveys of all vehicle types across the study area, estimates of likely behavioural responses to measures, local meteorological data, terrain data and air quality data.
Welsh: Gall enghreifftiau o gasglu data gynnwys arolygon traffig o bob math o gerbyd yn ardal yr astudiaeth, amcangyfrifon o ymatebion ymddygiadol tebygol i fesurau, data meteorolegol lleol, data tirwedd a data ansawdd aer.
English: Data should be representative of the range of conditions expected over long term annual periods to ensure local assessments are robust.
Welsh: Dylai data fod yn gynrychioliadol o'r gwahanol amodau a ddisgwylir dros gyfnodau blynyddol hirdymor er mwyn sicrhau bod asesiadau lleol yn gadarn.
English: Traffic surveys should cover the major routes that will provide effective coverage of journeys in the study area (the area expected to be affected significantly by measures to be implemented under the local plan).
Welsh: Dylai arolygon trafnidiaeth gynnwys y prif ffyrdd a fydd yn cwmpasu teithiau i mewn i ardal yr astudiaeth yn effeithiol (yr ardal y disgwylir i'r mesurau sydd i'w rhoi ar waith o dan y cynllun lleol effeithio arni'n sylweddol).
English: The surveys may be undertaken on a number of roads (non-compliant and adjacent compliant roads in the study area) for a sustained period of time (weeks to months).
Welsh: Gellir cynnal yr arolygon ar nifer o ffyrdd (ffyrdd nad ydynt yn cydymffurfio a ffyrdd cyfagos sy'n cydymffurfio yn ardal yr astudiaeth) am gyfnod estynedig o amser (wythnosau i fisoedd).
English: Further data may need to be captured following development of the initial plan in support of the preferred option.
Welsh: Efallai y bydd angen casglu rhagor o ddata ar ôl i'r cynllun cychwynnol gael ei ddatblygu er mwyn cefnogi'r opsiwn a ffefrir.
English: Air quality monitoring data should be measured using roadside monitors located within the study area.
Welsh: Dylai data monitro ansawdd aer gael eu mesur gan ddefnyddio monitorau wrth ymyl y ffordd wedi'u lleoli o fewn ardal yr astudiaeth.
English: Local meteorological data should also be measured at the same time as the air quality data.
Welsh: Dylai data meteorolegol lleol hefyd gael eu mesur ar yr un pryd â'r data ar ansawdd aer.
English: Remedial options will need to be scoped and developed, informed by local engagement, prior to commencing assessments.
Welsh: Bydd angen cwmpasu a datblygu opsiynau adferol, wedi'u llywio gan ymgysylltu lleol, cyn dechrau asesiadau.
English: The local modelling will need to assess a range of scenarios and be based on robust and representative data, including the data referred to above.
Welsh: Bydd angen i'r gwaith modelu lleol asesu nifer o senarios a bod yn seiliedig ar ddata cadarn a chynrychioliadol, gan gynnwys y data y cyfeirir atynt uchod.
English: Air dispersion modelling is expected to be required throughout the study period to underpin all stages of the options appraisal process, and continue to be refined as new data becomes available, beginning once input data has been pre-processed and transport and other local emissions data are available.
Welsh: Disgwylir y bydd angen gwneud gwaith modelu tryledu aer drwy gydol cyfnod yr astudiaeth er mwyn ategu pob cam o'r broses o arfarnu opsiynau, ac y bydd angen parhau i'w fireinio wrth i ddata newydd fod ar gael, gan ddechrau unwaith bod y data mewnbwn wedi cael eu rhagbrosesu a bod data ar drafnidiaeth a data eraill ar allyriadau lleol ar gael.
English: Timings will depend on the availability of robust datasets and the complexity of the local situation and of the measures proposed.
Welsh: Bydd amseriadau yn dibynnu ar argaeledd setiau data cadarn a chymhlethdod y sefyllfa leol a'r mesurau a gynigir.
English: Options will be assessed and evaluated as soon as information becomes available, in parallel with the local assessments and consultation.
Welsh: Caiff opsiynau eu hasesu a'u gwerthuso cyn gynted ag y bydd gwybodaeth ar gael, ochr yn ochr â'r asesiadau a'r ymgynghori lleol.
English: The HM Treasury Green Book approach provides an iterative process to the development of the business case.
Welsh: Mae dull gweithredu Llyfr Gwyrdd Trysorlys EM yn cynnig proses iterus o ddatblygu'r achos busnes.
English: A robust options appraisal, including an assessment of the wider impacts of an option, is an important part of the business case.
Welsh: Mae arfarniad cadarn o opsiynau, gan gynnwys asesiad o effeithiau ehangach opsiwn, yn rhan bwysig o'r achos busnes.
English: The broad aim of the options appraisal process is to demonstrate that the preferred option of a scheme delivers compliance within the shortest possible time.
Welsh: Nod cyffredinol y broses o arfarnu opsiynau yw dangos bod yr opsiwn a ffefrir mewn cynllun yn sicrhau cydymffurfiaeth cyn gynted â phosibl.
English: This requires demonstrating that a range of options have been considered and assessed in a consistent way, so that there is confidence in the preferred option.
Welsh: Mae hyn yn ei gwneud yn ofynnol dangos bod nifer o opsiynau wedi cael eu hystyried a'u hasesu mewn ffordd gyson, fel y bydd hyder yn yr opsiwn a ffefrir.
English: The first stage of the options appraisal process is generating a broad list (examining all potential locally effective options) and reducing it to a shortlist of options that the local authority proposes to explore further, forming the main element of a local authority's initial plan.
Welsh: Y cam cyntaf o'r broses o arfarnu opsiynau yw llunio rhestr gyffredinol (sy'n ystyried pob opsiwn posibl a all fod yn effeithiol yn lleol) a'i throi'n rhestr fer o opsiynau y mae'r awdurdod lleol yn cynnig y dylid eu hystyried ymhellach, sy'n ffurfio prif elfen cynllun cychwynnol awdurdod lleol.
English: Initial modelling outputs, particularly air quality and transport, should facilitate this high level assessment.
Welsh: Dylai allbynnau modelu cychwynnol, yn enwedig ansawdd aer a thrafnidiaeth, hwyluso'r broses asesu lefel uchel hon.
English: The initial plan should include all latest evidence deliverables.
Welsh: Dylai'r cynllun cychwynnol gynnwys yr holl opsiynau y gellir eu cyflawni yn ôl y dystiolaeth.
English: The HM Treasury Green Book approach includes consideration of value for money.
Welsh: Mae dull gweithredu Llyfr Gwyrdd Trysorlys EM yn cynnwys ystyried gwerth am arian.
English: However, for the purpose of this feasibility study the determining factor when selecting measures to tackle air quality must be their effectiveness, not their cost.
Welsh: Fodd bynnag, at ddiben yr astudiaeth ddichonoldeb hon, rhaid mai'r ffactor sy'n penderfynu wrth ddewis mesurau i fynd i'r afael ag ansawdd aer yw eu heffeithiolrwydd, yn hytrach na'u cost.
English: Local authorities must identify which measures will meet the legal limits in the shortest time.
Welsh: Mae'n rhaid i awdurdodau lleol nodi pa fesurau fydd yn cyflawni'r terfynau cyfreithlon cyn gynted â phosibl.
English: The only situation in which cost can be taken into consideration is where there are two equally effective measures.
Welsh: Yr unig sefyllfa lle y gellir ystyried cost yw'r sefyllfa lle ceir dau fesur yr un mor effeithiol.
English: For instance, only where two measures can be shown to be equally effective at bringing forward the likely date of compliance can the local authority lawfully choose the lowest cost option.
Welsh: Er enghraifft, dim ond lle y gellir dangos bod dau fesur yr un mor effeithiol o ran sicrhau cydymffurfiaeth cyn y dyddiad cydymffurfio tebygol y gall yr awdurdod lleol ddewis yr opsiwn cost isaf yn gyfreithlon.
English: Therefore, cost benefit analysis is not an appropriate primary method for selecting measures which would be most effective in bringing forward the likely compliance date.
Welsh: Felly, nid yw dadansoddiad cost a budd yn brif ddull priodol o ddewis y mesurau a fyddai fwyaf effeithiol o ran sicrhau cydymffurfiaeth cyn y dyddiad cydymffurfio tebygol.
English: The Welsh Government anticipates this stage could take the local authority up to 2 months in cumulative time to develop and clear prior to submission to the Welsh Government.
Welsh: Mae Llywodraeth Cymru yn rhagweld y gallai gymryd hyd at ddeufis mewn amser cronnus i'r awdurdod lleol ddatblygu'r cam hwn a'i gymeradwyo cyn ei gyflwyno i Lywodraeth Cymru.
English: The Welsh Government requested local authorities to submit initial plans by 30 September which should set out the case for change and identify options to accelerate compliance, including indicative costs.
Welsh: Gofynnodd Llywodraeth Cymru i awdurdodau lleol gyflwyno cynlluniau cychwynnol erbyn 30 Medi a ddylai amlinellu'r achos dros newid a nodi opsiynau i sicrhau cydymffurfiaeth yn gynt, gan gynnwys costau dangosol.
English: Cardiff Council submitted their initial plan to Welsh Ministers on 30 September and has published it on their website.
Welsh: Cyflwynodd Cyngor Caerdydd ei gynllun cychwynnol i Weinidogion Cymru ar 30 Medi ac mae wedi'i gyhoeddi ar ei wefan.
English: Their plan can be viewed at the following web link:

Welsh: Rhif ffôn:
English: The Welsh Government has established an expert panel to undertake an independent assessment of the interim and final plans which will advise Welsh Ministers and ensure measures in the plans deliver compliance in the soonest time.
Welsh: Mae Llywodraeth Cymru wedi sefydlu panel arbenigol i gynnal asesiad annibynnol o'r cynlluniau interim a therfynol a chynghori Gweinidogion Cymru a sicrhau bod y mesurau yn y cynlluniau yn sicrhau cydymffurfiaeth cyn gynted â phosibl.
English: Sufficient time should be provided for all stakeholders to consider the local proposals and respond to local consultations.
Welsh: Dylid rhoi digon o amser i bob rhanddeiliad ystyried y cynigion lleol ac ymateb i ymgyngoriadau lleol.
English: The Welsh Government anticipates that significant measures affecting local citizens will require local consultation, which is likely to run for up to 3 months.
Welsh: Mae Llywodraeth Cymru yn rhagweld y bydd angen cynnal ymgynghoriad lleol ar fesurau sylweddol sy'n effeithio ar ddinasyddion lleol, sy'n debygol o bara am hyd at dri mis.
English: Drafting of a consultation is likely to take up to a month, drawing on emerging data and proposals for a preferred measure.
Welsh: Mae'n debygol y bydd yn cymryd hyd at fis i ddrafftio ymgynghoriad, gan ddefnyddio'r data sy'n dod i'r golwg a chynigion ar gyfer mesur a ffefrir.
English: Final plans and a full business case must be submitted to the Welsh Ministers by the end of June 2019 at the latest.
Welsh: Rhaid i gynlluniau terfynol ac achos busnes llawn gael eu cyflwyno i Weinidogion Cymru erbyn diwedd mis Mehefin 2019 fan bellaf.
English: The business case will describe the final, preferred, option for delivering compliance in the shortest possible time.
Welsh: Bydd yr achos busnes yn disgrifio'r opsiwn terfynol, a ffefrir, ar gyfer sicrhau cydymffurfiaeth cyn gynted â phosibl.
English: These plans could take up to 3 months, following local consultation, to develop and sign-off prior to submission to the Welsh Ministers.
Welsh: Gallai'r cynlluniau hyn gymryd hyd at dri mis, yn dilyn ymgynghoriad lleol, i'w datblygu a'u cymeradwyo cyn eu cyflwyno i Weinidogion Cymru.
English: Following consideration and approval of the plans, the Welsh Ministers will require (by Direction) Cardiff Council to implement the measure or measures in the plans which deliver compliance in the soonest possible time.
Welsh: Ar ôl ystyried a chymeradwyo'r cynlluniau, bydd Gweinidogion Cymru yn ei gwneud yn ofynnol (drwy Gyfarwyddyd) i Gyngor Caerdydd roi'r mesur neu'r mesurau yn y cynlluniau sy'n sicrhau cydymffurfiaeth cyn gynted â phosibl ar waith.
English: Implementation of the plans will depend on the nature of the measures identified.
Welsh: Bydd y broses o roi'r cynlluniau ar waith yn dibynnu ar natur y mesurau a nodwyd.
English: Significant measures could require a period of infrastructure procurement and installation, for example signs, traffic management systems and cameras.
Welsh: Gallai mesurau sylweddol ofyn am gyfnod o gaffael a gosod seilwaith, er enghraifft arwyddion, systemau rheoli traffig a chamerâu.
English: This would be expected to take up to six months.
Welsh: Byddai disgwyl i hyn gymryd hyd at chwe mis.
English: A period of systems testing and local engagement may also be likely to take up to six months to enable businesses and individuals to adjust.
Welsh: Efallai y bydd cyfnod o brofi systemau ac ymgysylltu lleol hefyd yn debygol o gymryd hyd at chwe mis er mwyn galluogi busnesau ac unigolion i ymaddasu.
English: The Welsh Government expects implementation of Clean Air Zones could take up to three years from the start of the assessment process (i.e. by the end of 2020), achieving compliance in 2021.
Welsh: Mae Llywodraeth Cymru yn disgwyl y gallai gymryd hyd at dair blynedd (h.y. erbyn diwedd 2020) i roi Parthau Aer Glân ar waith, gan sicrhau cydymffurfiaeth yn 2021.
English: Unless Cardiff Council identifies an alternative measure or measures which would bring the roads for which they are responsible (in the Cardiff Urban Area and South Wales zone) into compliance at least as quickly as a charging CAZ, Cardiff Council will be required by direction to introduce a charging CAZ.
Welsh: Oni fydd Cyngor Caerdydd yn nodi mesur neu fesurau amgen a fyddai'n sicrhau bod y ffyrdd y mae'n gyfrifol amdanynt (yn Ardal Drefol Caerdydd a pharth De Cymru) yn cydymffurfio o leiaf mor gyflym â Pharth Aer Glân lle y codir tâl, bydd yn ofynnol i Gyngor Caerdydd drwy gyfarwyddyd gyflwyno Parth Aer Glân lle y codir tâl.
English: On 9 March 2018, the Welsh Ministers issued a Direction entitled 'Environment Act 1995 (Feasibility Study for Nitrogen Dioxide Compliance) Air Quality Direction 2018'
Welsh: Ar 9 Mawrth 2018, rhoddodd Gweinidogion Cymru gyfarwyddyd yn dwyn y teitl 'Cyfarwyddyd Ansawdd Aer Deddf yr Amgylchedd 1995 (Astudiaeth Ddichonoldeb ar gyfer Cydymffurfiaeth Nitrogen Deuocsid' 2018'
English: Environment Act 1995 (Feasibility Study for Nitrogen Dioxide Compliance) Air Quality Direction 2018 - https://gov.wales/legislation/subordinate/nonsi/epwales/2018/180430-feasibility-study-for-nitrogen-dioxidecompliance-air-quality-direction-2018/?lang=en
Welsh: Cyfarwyddyd Ansawdd Aer Deddf yr Amgylchedd 1995 (Astudiaeth Ddichonoldeb ar gyfer Cydymffurfiaeth Nitrogen Deuocsid) 2018 - https://gov.wales/legislation/subordinate/nonsi/epwales/2018/180430-feasibility-study-for-nitrogen-dioxidecompliance-air-quality-direction-2018/?lang=cy
English: The basis for the timeline is described below, covering data collection, transport, air quality and economic modelling of the local situation, options assessment, production of an initial plan (outlining an initial long list of options to refine to a short list for further assessment) local consultation and production and approval by the Welsh Ministers of a final business case/plan (for a preferred option/measure).
Welsh: Disgrifir y sail dros yr amserlen isod, sy'n cwmpasu casglu data, trafnidiaeth, ansawdd aer a gwaith modelu economaidd ar y sefyllfa leol, asesu opsiynau, paratoi cynllun cychwynnol (sy'n amlinellu rhestr hir gychwynnol o opsiynau i'w mireinio'n rhestr fer i'w hasesu ymhellach) ymgynghoriad lleol a pharatoi achos busnes/cynllun terfynol (ar gyfer opsiwn/mesur a ffefrir) i'w gymeradwyo gan Weinidogion Cymru.
English: However, Caerphilly County Borough Council will develop its own timeline for determining measures and implementing them as part of their business cases to achieve compliance in the soonest time.
Welsh: Fodd bynnag, bydd Cyngor Bwrdeistref Sirol Caerffili yn datblygu ei amserlen ei hun ar gyfer penderfynu ar fesurau a'u rhoi ar waith fel rhan o'i achosion busnes i sicrhau cydymffurfiaeth cyn gynted â phosibl.
English: Caerphilly County Borough Council's timeline will depend on the scale and complexity of the local situation and the remedial options considered.
Welsh: Mae amserlen Cyngor Bwrdeistref Sirol Caerffili yn dibynnu ar raddfa a chymhlethdod y sefyllfa leol a'r opsiynau adferol a ystyrir.
English: The Welsh Government is working with Caerphilly County Borough Council throughout the process to provide guidance and ensure timelines are the shortest possible, and will require delivery ahead of the dates in the direction where it is possible to do so.
Welsh: Bydd Llywodraeth Cymru yn gweithio gyda Chyngor Bwrdeistref Sirol Caerffili drwy gydol y broses er mwyn rhoi arweiniad a sicrhau bod yr amserlenni mor fyr â phosibl, y bydd angen eu cyflawni cyn y dyddiadau yn y cyfarwyddyd lle y bo modd gwneud hynny.
English: Caerphilly County Borough Council must undertake the feasibility assessment in accordance with the HM Treasury's Green Book approach, a recognised business case model used across UK Governments and public bodies.
Welsh: Mae'n rhaid i Gyngor Bwrdeistref Sirol Caerffili gynnal yr asesiad o ddichonoldeb yn unol â Llyfr Gwyrdd Trysorlys EM, sef model achos busnes a gydnabyddir sy'n cael ei ddefnyddio gan Lywodraethau'r DU a chyrff cyhoeddus.
English: Examples of data required to be collected may include traffic surveys of all vehicle types across the study area, estimates of likely behavioural responses to measures, local meteorological data, terrain data and air quality data.
Welsh: Gall enghreifftiau o'r data y mae'n rhaid eu casglu gynnwys arolygon traffig o bob math o gerbyd yn ardal yr astudiaeth, amcangyfrifon o ymatebion ymddygiadol tebygol i fesurau, data meteorolegol lleol, data tirwedd a data ansawdd aer.
English: Further measurements may be required as the scenarios are developed to support confidence in the scenario assessments, and may continue following development of the initial plan in support of a preferred option.
Welsh: Efallai y bydd angen rhagor o fesuriadau wrth i'r senarios gael eu datblygu er mwyn cynnal hyder yn yr asesiadau o senarios, a gallant barhau ar ôl i'r cynllun cychwynnol gael ei ddatblygu i gefnogi'r opsiwn a ffefrir.
English: Air dispersion modelling is expected to be required throughout the study period to underpin all stages of the options appraisal process, and continue to be refined as new data becomes available, beginning once input data has been pre-processed and transport and other local emissions data are available.
Welsh: Disgwylir y bydd angen gwneud gwaith modelu tryledu aer drwy gydol cyfnod yr astudiaeth er mwyn ategu pob cam o'r broses o arfarnu opsiynau, a pharhau i'w mireinio wrth i ddata newydd fod ar gael, yn dechrau unwaith bod data mewnbwn wedi cael eu rhagbrosesu a bod data trafnidiaeth a data eraill ar allyriadau lleol ar gael.
English: The Welsh Government anticipates this stage could take the local authority up to 2 months in cumulative time to develop and clear prior to submission to the Welsh Government.
Welsh: Mae Llywodraeth Cymru yn rhagweld y gallai cymryd hyd at ddeufis mewn amser cronnus i'r awdurdod lleol ddatblygu'r cam hwn a'i gymeradwyo cyn ei gyflwyno i Lywodraeth Cymru.
English: Caerphilly County Borough Council submitted their initial plan to Welsh Ministers on 27 September and has published it on their website.
Welsh: Cyflwynodd Cyngor Bwrdeistref Sirol Caerffili ei gynllun cychwynnol i Weinidogion Cymru ar 27 Medi ac mae wedi'i gyhoeddi ar ei wefan.

Welsh: Rhif ffôn - 01443 811346
English: Sufficient time should be provided for all stakeholders to consider the local proposals and respond within local consultations.
Welsh: Dylid rhoi digon o amser i bob rhanddeiliad ystyried y cynigion lleol ac ymateb i ymgyngoriadau lleol.
English: The Welsh Government anticipates that significant measures affecting local citizens will require local consultation, which would run for up to 3 months.
Welsh: Mae Llywodraeth Cymru yn rhagweld y bydd angen cynnal ymgynghoriad lleol ar fesurau sylweddol sy'n effeithio ar ddinasyddion lleol, a fyddai'n para am hyd at dri mis.
English: Following consideration and approval of the plans, the Welsh Ministers will require (by Direction) Caerphilly County Borough Council to implement the measure or measures in the plans which deliver compliance in the soonest possible time.
Welsh: Ar ôl ystyried a chymeradwyo'r cynlluniau, bydd Gweinidogion Cymru yn ei gwneud yn ofynnol (drwy gyfarwyddyd) i Gyngor Bwrdeistref Sirol Caerffili roi'r mesur neu'r mesurau yn y cynlluniau sy'n sicrhau cydymffurfiaeth cyn gynted â phosibl ar waith.
English: The Welsh Government recognises that a Clean Air Zone may not be appropriate for the purposes of accelerating compliance in all cases.
Welsh: Mae Llywodraeth Cymru yn cydnabod na fydd Parth Aer Glân yn briodol o bosibl at ddibenion sicrhau cydymffurfiaeth yn gynt ym mhob achos.
English: For example, outside of urban areas where no alternative routes are available.
Welsh: Er enghraifft, y tu allan i ardaloedd trefol lle nad oes unrhyw lwybrau amgen ar gael.
English: In such situations, of which Hafod-yrynys is one, alternative measures may be required.
Welsh: Mewn sefyllfaoedd o'r fath, ac mae Hafod-yr-Ynys yn un ohonynt, efallai y bydd angen mesurau amgen.
English: The maximum time required to reach compliance in this area is currently uncertain and will be determined following Caerphilly County Borough Council's feasibility study.
Welsh: Mae'r mwyafswm amser sydd ei angen i gydymffurfio yn yr ardal hon yn ansicr ar hyn o bryd a chaiff ei bennu yn dilyn astudiaeth ddichonoldeb Cyngor Bwrdeistref Sirol Caerffili.
English: The Welsh Government expects that the local authority will begin to implement the most effective measures identified in the study (including potential infrastructure measures) by October 2019 and that they will be completed as soon as possible, and by the end of December 2020 at the latest, to achieve compliance by 2021 and sooner if possible.
Welsh: Mae Llywodraeth Cymru yn disgwyl y bydd yr awdurdod lleol yn dechrau rhoi'r mesurau mwyaf effeithiol a nodwyd yn yr astudiaeth (gan gynnwys mesurau seilwaith posibl) ar waith erbyn mis Hydref 2019 ac yn eu cwblhau cyn gynted â phosibl, ac erbyn diwedd mis Rhagfyr 2020, er mwyn sicrhau cydymffurfiaeth erbyn 2021 ac yn gynt os oes modd.
English: Following concerns that the measured levels at this location were highly likely to be influenced by the unusual siting of the existing monitoring station, the Welsh Government commissioned an expert review.
Welsh: Yn dilyn pryderon bod lleoliad anarferol yr orsaf fonitro bresennol yn debygol iawn o fod wedi dylanwadu ar y lefelau a fesurwyd yn y lleoliad hwn, comisiynodd Llywodraeth Cymru adolygiad gan arbenigwr.
English: Resolution of the issue is ongoing.
Welsh: Mae'r mater eto i'w ddatrys.
English: However, in light of the local monitoring and modelling data collected and assessed by Caerphilly County Borough Council as part of its feasibility study assessment we are confident that their proposals to address non-compliance in the soonest time are based on robust evidence.
Welsh: Fodd bynnag, yng ngoleuni'r data monitro a modelu lleol a gasglwyd ac a aseswyd gan Gyngor Bwrdeistref Sirol Caerffili fel rhan o'i astudiaeth ddichonoldeb, rydym yn hyderus bod ei gynigion i fynd i'r afael â diffyg cydymffurfiaeth cyn gynted â phosibl yn seiliedig ar dystiolaeth gadarn.
English: Therefore the siting of the monitor is no longer material to this WGSP.
Welsh: Felly, nid yw lleoliad y monitor yn berthnasol mwyach i'r Cynllun Atodol hwn gan Lywodraeth Cymru.
