English: Welsh Government support for Cardiff Council and Caerphilly County Borough Council
Welsh: Cymorth Llywodraeth Cymru i Gyngor Caerdydd a Chyngor Bwrdeistref Sirol Caerffili
English: To support the development and implementation of feasibility studies, the Welsh Government has:
Welsh: Er mwyn cefnogi'r broses o ddatblygu astudiaethau dichonoldeb a'u rhoi ar waith, mae Llywodraeth Cymru wedi:
English: Shared details of the road links identified as non-compliant in the national PCM model.
Welsh: Rhannu manylion am y ffyrdd cyswllt y nodwyd nad oeddent yn cydymffurfio yn y model Mapio Hinsawdd Llygredd cenedlaethol.
English: Provided supporting information and guidance to inform the process and expected information required in feasibility studies including:
Welsh: Rhoi gwybodaeth ac arweiniad ategol er mwyn llywio'r broses ynghyd â gwybodaeth y byddid yn disgwyl bod ei hangen mewn astudiaethau dichonoldeb, gan gynnwys:
English: This involves frequent meetings, with each local authority and ongoing appraisal and feedback as each study has progressed.
Welsh: Mae hyn yn cynnwys cyfarfodydd mynych, â phob awdurdod lleol a gwaith arfarnu ac adborth parhaus wrth i bob astudiaeth fynd yn ei blaen.
English: Allocated over £20 million for an Air Quality Fund through to 2021 to help accelerate compliance with NO
Welsh: Wedi dyrannu dros £20 miliwn ar gyfer Cronfa Ansawdd Aer hyd at 2021 er mwyn helpu i sicrhau cydymffurfiaeth â'r terfynau ar gyfer NO2 yn gynt a gwella ansawdd aer yng Nghymru.
English: The Air Quality Fund will primarily be used to provide ongoing support, guidance and finance to enable Cardiff Council and Caerphilly County Borough Council to take action to achieve compliance with legal limits for NO
Welsh: Caiff y Gronfa Ansawdd Aer ei defnyddio'n bennaf i roi cymorth, arweiniad a chyllid parhaus er mwyn galluogi Cyngor Caerdydd a Chyngor Bwrdeistref Sirol Caerffili i gymryd camau i sicrhau cydymffurfiaeth â'r terfynau cyfreithlon ar gyfer NO
English: The funding will support the work of these local authorities to conduct feasibility studies, implement early measures which help accelerate exposure reduction and deliver the options which will achieve compliance with limit values in the shortest possible time.
Welsh: Bydd y cyllid yn helpu'r awdurdodau lleol hyn i gynnal astudiaethau dichonoldeb, rhoi mesurau cynnar ar waith a fydd yn helpu i gyflymu'r broses o leihau amlygiad a chyflwyno'r opsiynau a fydd yn sicrhau cydymffurfiaeth â'r gwerthoedd terfyn cyn gynted â phosibl.
English: Local Solutions on Welsh Government Managed Road Networks
Welsh: Atebion Lleol ar y Rhwydweithiau Ffyrdd a Reolir gan Lywodraeth Cymru
English: As the relevant highway authority, the Welsh Ministers have direct responsibility for the motorway and trunk road network in Wales.
Welsh: Fel yr awdurdod priffyrdd perthnasol, mae gan Weinidogion Cymru gyfrifoldeb uniongyrchol dros y rhwydwaith traffyrdd a chefnffyrdd yng Nghymru.
English: Exceedances of legal limits for NO
Welsh: Nodwyd achosion o fynd y tu hwnt i'r terfynau cyfreithlon ar gyfer NO2 ar y darnau ar wahân canlynol o'r draffordd a'r gefnffordd y tu allan i Ardaloedd Trefol Caerdydd ac Abertawe:
English: A494 at Deeside (North Wales Zone);
Welsh: yr A494 yng Nglannau Dyfrdwy (Parth Gogledd Cymru);
English: A483 near Wrexham (North Wales Zone);
Welsh: yr A483 ger Wrecsam, (Parth Gogledd Cymru);
English: M4 between Junctions 41 and 42 at Port Talbot (Swansea and South Wales Zone);
Welsh: yr M4 rhwng Cyffyrdd 41 a 42 ym Mhort Talbot, (Abertawe a Pharth De Cymru);
English: M4 between Junctions 25 and 26 at Newport (South Wales Zone);
Welsh: (iv) yr M4 rhwng Cyffyrdd 25 a 26 yng Nghasnewydd (Parth De Cymru);
English: and (v) A470 between Upper Boat and Pontypridd (South Wales Zone).
Welsh: (v) yr A470 rhwng Glan-bad a Phontypridd (Parth De Cymru).
English: These areas are geographically isolated from each other, and have been assessed on an individual basis.
Welsh: Mae'r ardaloedd hyn yn ddaearyddol ar wahân i'w gilydd, ac maent wedi cael eu hasesu'n unigol.
English: The Welsh Ministers have adopted a precautionary approach to the identification of measures.
Welsh: Mae Gweinidogion Cymru wedi mabwysiadu dull gweithredu'n rhagofalus o nodi mesurau.
English: A measure has been identified for implementation, unless there is reasonable scientific certainty that it would
Welsh: Mae mesur wedi cael ei nodi i'w roi ar waith, oni bai fod sicrwydd gwyddonol rhesymol
English: Where more than one measure or a package of measures has been identified as accelerating compliance with the limit values, the Welsh Ministers have identified the measure or a package of measures that will accelerate compliance in a way which reduces NO
Welsh: Pan fydd mwy nag un mesur neu becyn o fesurau wedi'i nodi fel un neu rai a fydd yn sicrhau cydymffurfiaeth â'r gwerthoedd terfyn yn gynt, mae Gweinidogion Cymru wedi nodi'r mesur neu becyn o fesurau a fydd yn sicrhau cydymffurfiaeth yn gynt mewn ffordd sy'n lleihau crynodiadau o NO
English: Where more than one measure or package of measures has been identified as taking the same time to accelerate compliance, the Welsh Ministers have identified the measure or package of measures that has been assessed as being the most likely to accelerate compliance.
Welsh: Pan fydd mwy nag un mesur neu becyn o fesurau wedi'i nodi fel un neu rai a fydd yn cymryd yr un amser i sicrhau cydymffurfiaeth yn gynt, mae Gweinidogion Cymru wedi nodi'r mesur neu becyn o fesurau yr aseswyd mai hwy fyddai fwyaf tebygol o sicrhau cydymffurfiaeth yn gynt.
English: The assessment of measures has been predominantly based on using the Pollution Climate Mapping (PCM) model (2017) to define the future conditions and the assessment of measures using micro simulation traffic models focused on exceedance areas and air quality models using the Defra emission factor toolkit and air quality dispersion models adjusted with local monitoring, which is recognised practice for air quality assessments and is also the best available information.
Welsh: Mae'r asesiad o fesurau wedi'i seilio'n bennaf ar ddefnyddio'r model Mapio Hinsawdd Llygredd (2017) i ddiffinio amodau yn y dyfodol ac asesu mesurau gan ddefnyddio modelau traffig micro-efelychu sy'n canolbwyntio ar ardaloedd lle ceir gormodiant a modelau ansawdd aer sy'n defnyddio pecyn cymorth ffactorau allyriadau Defra a modelau tryledu ansawdd aer wedi'u haddasu â gwaith monitro lleol, sef arfer cydnabyddedig ar gyfer asesu ansawdd aer a hefyd y wybodaeth orau sydd ar gael.
English: Ongoing on site air quality monitoring is being undertaken to supplement the PCM information.
Welsh: Parheir i fonitro ansawdd aer ar y safle er mwyn ategu gwybodaeth Mapio Hinsawdd Llygredd.
English: Further measures have been included in this plan should the PCM data transpire to be lower than the on site results.
Welsh: Mae rhagor o fesurau wedi cael eu cynnwys yn y cynllun hwn pe bai data Mapio Hinsawdd Llygredd yn is na'r canlyniadau ar y safle.
English: For instance, NO
Welsh: Er enghraifft, mae'r crynodiadau o NO
English: These measures have been classed as 'precautionary retained measures' (PRM).
Welsh: Mae'r mesurau hyn wedi cael eu dosbarthu'n 'fesurau rhagofalus a ddargedwir'.
English: It should also be recognised that these PRM have the ability to reduce NO
Welsh: Dylid cydnabod hefyd y gallai'r mesurau rhagofalus a ddargedwir hyn leihau crynodiadau o NO2, ond y byddent yn methu â sicrhau cydymffurfiaeth cyn gynted â phosibl.
English: These measures require either a time period beyond that which could be achieved with alternative measures or rely on third party involvement and are not capable of being directly controlled by the Welsh Ministers.
Welsh: Mae'r mesurau hyn naill ai'n gofyn am gyfnod amser y tu hwnt i'r hyn y gellid ei gyflawni gyda mesurau amgen neu'n dibynnu ar ymwneud trydydd parti ac na allant gael eu rheoli'n uniongyrchol gan Weinidogion Cymru.
English: To assess the measures required at the 5 locations, the Welsh Transport Appraisal Guidance (WelTAG) has been used whilst also satisfying the requirements of the Directive and Regulations.
Welsh: Er mwyn asesu'r mesurau sydd eu hangen yn y pum lleoliad, defnyddiwyd Arweiniad ar Arfarnu a Chynllunio Trafnidiaeth Cymru (WelTAG) tra'n bodloni gofynion y Gyfarwyddeb a'r Rheoliadau hefyd.
English: WelTAG provides a robust framework
Welsh: Mae WelTAG yn cynnig fframwaith cadarn
English: In this case the focus is on air quality and the objective set is to identify measures which will assist in bringing forward reductions in NO
Welsh: Yn yr achos hwn, mae'r ffocws ar ansawdd aer a'r amcan a bennwyd yw nodi mesurau a fydd yn helpu i leihau NO
English: WelTAG studies are taken forward in stages of increasing detail as potentially effective measures move through identification, comparison and selection.
Welsh: Caiff astudiaethau WelTAG eu datblygu mewn camau cynyddol fanwl wrth i'r mesurau effeithiol posibl symud drwy broses nodi, cymharu a dewis.
English: The outcome is a set of measures or packages of measures that are most likely to be effective in achieving compliance in the shortest possible time at a particular location.
Welsh: Y canlyniad yw set o fesurau neu becynnau o fesurau sydd fwyaf tebygol o fod yn effeithiol o ran sicrhau cydymffurfiaeth cyn gynted â phosibl mewn lleoliad penodol.
English: WelTAG Stage 1 (Strategic Outline Case) identifies a long list of viable measures and, depending on their fit with the objective, is used to select a short list for further consideration.
Welsh: Mae Cam 1 WelTAG (Achos Amlinellol Strategol) yn nodi rhestr hir o fesurau hyfyw ac, yn dibynnu ar y graddau y maent yn cydweddu â'r amcan, a chaiff ei defnyddio i ddewis rhestr fer i'w hystyried ymhellach.
English: Following further investigation, WelTAG Stage 2 (Outline Business Case) is used to select measures on the basis of their performance against the objective preferred measures to be taken forward.
Welsh: Ar ôl rhagor o ymchwilio, defnyddir Cam 2 WelTAG (Achos Busnes Amlinellol) i ddewis mesurau ar sail eu perfformiad yn erbyn mesurau a ffefrir i'w rhoi ar waith yr amcan.
English: WelTAG Stage 3 (Full Business Case) is used to make a full and detailed assessment of preferred measures to inform a final decision on their implementation.
Welsh: Defnyddir Cam 3 WelTAG (Achos Busnes Llawn) i gynnal asesiad llawn a manwl o'r mesurau a ffefrir er mwyn llywio penderfyniad terfynol ar eu rhoi ar waith.
English: In order to quantify the potential benefits at WelTAG Stage 3 detailed traffic and emissions/ dispersion modelling have been undertaken.
Welsh: Er mwyn mesur y manteision posibl ar Gam 3 WelTAG mae gwaith modelu traffig ac allyriadau/tryledu manwl wedi cael ei wneud.
English: This includes reviewing traffic data, reviewing air quality monitoring results, developing a base year air quality model, generating baseline emissions data, verifying the base year air quality model, developing options models, developing options emissions data, limit value compliance assessments, re-run options models, re-run emissions options data and re-run limit value compliance assessments for each of the 5 locations.
Welsh: Mae hyn yn cynnwys adolygu data trafnidiaeth, adolygu canlyniadau monitro ansawdd aer, datblygu model ansawdd aer blwyddyn sylfaen, paratoi data allyriadau llinell sylfaen, dilysu'r model ansawdd aer blwyddyn sylfaen, datblygu modelau opsiynau, datblygu data ar allyriadau opsiynau, asesiadau o gydymffurfiaeth â gwerthoedd terfyn, ail-redeg modelau opsiynau, ailredeg data opsiynau allyriadau ac ail-redeg asesiadau o gydymffurfiaeth â gwerthoedd terfyn ar gyfer pob un o'r pum lleoliad.
English: WelTAG Stages 1, 2 and 3 were completed between December 2017 and September 2018 in order to inform the production of this plan.
Welsh: Cafodd Camau 1, 2 a 3 WelTAG eu cwblhau rhwng mis Rhagfyr 2017 a mis Medi 2018 er mwyn llywio'r broses o baratoi'r cynllun hwn.
English: At WelTAG Stages 1 and 2, a long list of measures was identified and then scrutinised and reviewed to provide a short list that was taken forward to the WelTAG Stage 3 process.
Welsh: Ar Gamau 1 a 2 WelTAG, nodwyd rhestr hir o fesurau ac yna craffwyd arnynt a chynhaliwyd adolygiad ohonynt er mwyn paratoi rhestr fer ar gyfer Cam 3 o broses WelTAG.
English: WelTAG Stage 1 included around 50 to 60 potential measures reduced from approximately 400 initial measures for all 5 sites, and a shortlist was assessed semiqualitatively in WelTAG Stage 2.
Welsh: Roedd Cam 1 WelTAG yn cynnwys tua 50 i 60 o fesurau posibl ar ôl cwtogi ar tua 400 o fesurau cychwynnol a gyflwynwyd ar gyfer y pum safle, ac aseswyd rhestr fer yn lled-ansoddol ar Gam 2 WelTAG.
English: Due to the large number of measures considered, appraisal of their impact on air quality at WelTAG Stage 1 was undertaken using professional judgement.
Welsh: Oherwydd y nifer fawr o fesurau a ystyriwyd, arfarnwyd eu heffaith ar ansawdd aer ar Gam 1 WelTAG drwy arfer barn broffesiynol.
English: The WelTAG Stage 2 appraisal (including traffic and air quality monitoring data) used emissions and dispersion modelling but was based on assumed changes in traffic flow characteristics and volume for each measure.
Welsh: Roedd arfarniad Cam 2 WelTAG (gan gynnwys data monitro traffig ac ansawdd aer) yn defnyddio gwaith modelu allyriadau a thryledu ond roedd yn seiliedig ar newidiadau tybiedig yn nodweddion llif traffig a chyfaint traffig ar gyfer pob mesur.
English: Between 25 April and 19 June 2018, the Welsh Government consulted on the draft supplemental plan to the UK plan for tackling roadside nitrogen dioxide concentrations 2017.
Welsh: Rhwng 25 Ebrill a 19 Mehefin 2018, ymgynghorodd Llywodraeth Cymru ar y cynllun atodol drafft i gynllun y DU ar gyfer mynd i'r afael â chrynodiadau o nitrogen deuocsid wrth ymyl y ffordd 2017.
English: This included the outcome of WelTAG stages 1 and 2.
Welsh: Roedd hyn yn cynnwys canlyniad camau 1 a 2 WelTAG.
English: As a result of the WelTAG Stage 2 assessment the Welsh Ministers implemented speed restrictions at all 5 NO
Welsh: O ganlyniad i asesiad Cam 2 WelTAG rhoddodd Gweinidogion Cymru gyfyngiadau cyflymder ar waith ym mhob un o'r pum safle lle ceir gormodiant o NO2 ar ddiwedd mis Mehefin 2018 er mwyn lleihau lefelau ac amlygiad cyn gynted â phosibl.
English: These restrictions were identified as something which, without scientific doubt, would reduce exposure and speed up compliance with NO
Welsh: Nodwyd y byddai'r cyfyngiadau hyn yn rhywbeth, heb amheuaeth wyddonol, a fyddai'n lleihau amlygiad a sicrhau cydymffurfiaeth â'r gwerthoedd terfyn ar gyfer NO
English: The introduced measure at all 5 exceedance sites was:
Welsh: Y mesur a gyflwynwyd ym mhob un o'r pum safle lle ceir gormodiant oedd:
English: A reduced 50 mph speed limit (current speed limit 70 mph) over the length of the exceedance combined with variable message signs informing drivers of the reason for the new speed limit and encouraging smooth traffic flows*.
Welsh: Terfyn cyflymder is o 50 mya (y terfyn cyflymder yw 70mya ar hyn o bryd) ar hyd y gormodiant ynghyd â negeseuon newidiol ar arwyddion yn hysbysu gyrwyr am y rheswm dros y terfyn cyflymder newydd ac yn annog llifau traffig llyfn*.
English: (*The Variable Speed Limit (VSL) in place on the M4 through Newport is presently set to the lower limit overnight over the length of the exceedance.)
Welsh: (*Ar hyn o bryd mae'r Terfyn Cyflymder Newidiol sydd ar waith ar yr M4 drwy Gasnewydd wedi'i osod ar y terfyn is dros nos ar hyd y darn lle ceir gormodiant.)
English: The methodology adopted at WelTAG stage 3 is summarised in Annex G.
Welsh: Ceir crynodeb o'r fethodoleg a fabwysiadwyd ar Gam 3 WelTAG yn Atodiad G.
English: The Welsh Government published a consultation entitled 'Tackling roadside NO
Welsh: Cyhoeddodd Llywodraeth Cymru ymgynghoriad yn dwyn y teitl 'Mynd i'r afael â chrynodiadau o NO
English: Motorway and Trunk Road Network'
Welsh: Rhwydwaith Traffyrdd a Chefnffyrdd'
English: The consultation ran for a period of 6 weeks, closing on 2 November 2018.
Welsh: Cynhaliwyd yr ymgynghoriad am gyfnod o chwe wythnos, yn dod i ben ar 2 Tachwedd 2018.
English: The consultation sought views on the outcomes of the WelTAG Stage 3 assessments at each of the 5 NO

English: Summary of Responses to Welsh Government consultation on tackling roadside NO
Welsh: Crynodeb o'r Ymatebion i ymgynghoriad Llywodraeth Cymru ar fynd i'r afael â chrynodiadau o NO
English: The starting point for identifying the measures that are required by the Directive and the Regulations is the "baseline" at each relevant location.
Welsh: Y man cychwyn ar gyfer nodi'r mesurau sydd eu hangen o dan y Gyfarwyddeb a'r Rheoliadau yw'r "llinell sylfaen" ym mhob lleoliad perthnasol.
English: This refers to the concentrations of NO
Welsh: Mae hon yn cyfeirio at y crynodiadau o NO
English: The air quality baseline has been derived from a combination of national modelling (PCM model) and monitoring undertaken by the local authorities and the Welsh Government specifically for these appraisals.
Welsh: Mae'r llinell sylfaen ansawdd aer yn deillio o gyfuniad o waith model cenedlaethol (model Mapio Hinsawdd Llygredd) a gwaith monitro gan yr awdurdodau lleol a Llywodraeth Cymru yn benodol ar gyfer yr arfarniadau hyn.
English: The on site monitoring involved the use of triplicate diffusion tubes exposed for approximately two weeks at each of the relevant locations.
Welsh: Roedd y gwaith monitro ar y safle yn cynnwys defnyddio tair set o diwbiau tryledu a amlygwyd am tua phythefnos ym mhob un o'r lleoliadau perthnasol.
English: The diffusion tubes were located approximately 4 metres from the edge of the carriageway, at a height of approximately 2 metres.
Welsh: Cafodd y tiwbiau tryledu eu lleoli tua 4 metr o ymyl y lôn gerbydau, ar uchder o tua 2 fetr.
English: By the time the WelTAG Stage 3 reports were produced in August 2018, 6 months (12 exposure periods) of data was available.
Welsh: Erbyn i adroddiadau Cam 3 WelTAG gael eu paratoi ym mis Awst 2018, roedd chwe mis (12 o gyfnodau amlygu) o ddata ar gael.
English: Ideally, monitoring data should continue for a full year in order to enable calculation of annual averages.
Welsh: Yn ddelfrydol, dylai data monitro barhau am flwyddyn gyfan er mwyn cael cyfrifo cyfartaleddau blynyddol.
English: Therefore, monitoring will continue during the implementation of the measures referred to below to assess their effectiveness and inform future studies.
Welsh: Felly, bydd gwaith monitro yn parhau yn ystod y broses o roi'r mesurau y cyfeirir atynt isod ar waith er mwyn asesu eu heffeithiolrwydd a llywio astudiaethau yn y dyfodol.
English: In addition, as part of the WelTAG Stage 3 appraisal, locations have been identified for the installation of continuous monitoring stations to provide a reference method for monitoring the effect of the measures implemented (and to allow localised adjustment to the ongoing diffusion tube surveys).
Welsh: Hefyd, fel rhan o arfarniad Cam 3 WelTAG, cafodd lleoliadau eu nodi ar gyfer gosod gorsafoedd monitro parhaus er mwyn cynnig dull cyfeirio ar gyfer monitro effaith y mesurau a roddwyd ar waith (a rhoi cyfle i wneud addasiadau lleol i'r arolygon tiwbiau tryledu sy'n mynd rhagddynt).
English: Depending upon the implemented measures at each site, additional diffusion tube survey sites (beyond the ongoing seven sites at each exceedance location) may also be identified.
Welsh: Yn dibynnu ar y mesurau a roddir ar waith ar bob safle, efallai y caiff safleoedd ychwanegol ar gyfer arolygon tiwbiau tryledu (yn ychwanegol at y saith safle presennol ym mhob lleoliad lle y ceir gormodiant) eu nodi hefyd.
English: The predicted baseline NO
Welsh: Mae'r crynodiadau o NO
