English: The reason for this is the high volume of traffic travelling through the site and by diverting some of the traffic accelerates compliance.
Welsh: Y rheswm dros hyn yw'r lefel uchel o draffig sy'n teithio drwy'r safle a thrwy ddargyfeirio ychydig o'r traffig y gellir sicrhau cydymffurfiaeth yn gynt.
English: Also the road network in this area makes it suitable for variable diversions as there are a number of viable routes to Newport City Centre.
Welsh: Hefyd, mae'r rhwydwaith ffyrdd yn yr ardal hon yn ei gwneud yn addas ar gyfer llwybrau gwyro amrywiadwy gan fod nifer o lwybrau dichonadwy i Ganol Dinas Casnewydd.
English: The Welsh Ministers have taken a considered decision that speed restrictions with variable diversions are the only measure that will achieve compliance with the NO
Welsh: Mae Gweinidogion Cymru wedi gwneud penderfyniad ystyriol mai cyfyngiadau cyflymder â llwybrau gwyro amrywiadwy yw'r unig fesur a fydd yn sicrhau cydymffurfiaeth â'r gwerthoedd terfyn ar gyfer NO
English: The current 50mph speed limit is implemented via the Variable Speed Limit system.
Welsh: Rhoddir y terfyn cyflymder presennol o 50mya drwy'r system Terfyn Cyflymder Newidiol.
English: At present, the limit is only set overnight, but the intention is for it to be active at all times where the limit would otherwise be set at 60mph or the VSL would be inoperative, i.e. when the default National Speed Limit would apply.
Welsh: Ar hyn o bryd, dim ond dros nos y gosodir y terfyn, ond y bwriad yw y dylai fod yn weithredol drwy'r amser lle byddai'r terfyn fel arall wedi'i bennu'n 60mya neu lle na fyddai modd i'r terfyn cyflymder newidiol fod yn weithredol, h.y. pan fyddai'r Terfyn Cyflymder Cenedlaethol yn gymwys.
English: Limits lower than 50mph will still be utilised when traffic flows and road conditions dictate that a lower limit is necessary.
Welsh: Byddai terfynau o dan 50mya yn cael eu defnyddio o hyd pan fo angen terfyn is oherwydd llifau traffig ac amodau ar y ffordd.
English: M4 between Junctions 41 & 42 (Port Talbot) (Swansea & South Wales)
Welsh: M4 rhwng Cyffyrdd 41 a 42 (Port Talbot) (Abertawe a Pharth De Cymru)
English: The M4 through Port Talbot is on an elevated section of the M4 to the east of the site and on the western extent.
Welsh: Mae'r M4 drwy Bort Talbot ar ran lefel uwch o'r M4 i'r dwyrain i'r safle ac ar y cyrion gorllewinol.
English: The site crosses the River Neath and alongside the site are industrial/commercial parks and a railway line.
Welsh: Mae'r safle yn croesi Afon Nedd ac wrth ymyl y safle ceir parciau diwydiannol/masnachol a llinell reilffordd.
English: The site is semi urban.
Welsh: Mae'r safle yn lled-drefol.
English: To the eastern end of the site, there is currently a mandatory 50mph speed limit adjoining the site which is enforced with Average Speed Enforcement (ASE).
Welsh: Ym mhen dwyreiniol y safle, ceir terfyn cyflymder gorfodol o 50mya ar hyn o bryd yn gyffiniol â'r safle sy'n cael ei orfodi drwy Orfodi Cyflymder Cyfartalog.
English: Impact of measures on roadside annual mean concentrations (Equivalent PCM Concentration, μg/m
Welsh: Effaith mesurau ar groniadau cymedrig blynyddol wrth ymyl y ffordd (Crynodiad Mapio Hinsawdd Llygredd Cyfatebol, μg/m3) ar yr M4 Cyffordd 41-42
English: For all measures at this site, the amount of reduction in concentrations is between 2.33.5μg/m
Welsh: Ar gyfer pob mesur ar y safle hwn, caiff crynodiadau eu lleihau rhwng 2.3-3.5μg/m
English: Measures that do not achieve compliance any quicker than the proposed measure (speed limits) have not been progressed.
Welsh: Ni fwriedir parhau â mesurau nad ydynt yn sicrhau cydymffurfiaeth yn gynt na'r mesur a gynigir (terfynau cyflymder).
English: The distance chevrons, as with the A470 site, cause road safety concerns with the layout that can be achieved given the number and close proximity of slip roads on the site that will not allow the measure to be fully realised.
Welsh: Mae'r ceibrau pellter, fel yn achos y safle ar yr A470, yn achosi pryderon o ran diogelwch ar y ffordd oherwydd y drefn ffyrdd y gellir ei chyflawni, o ystyried nifer y ffyrdd ymuno/ymadael ar y safle a'r ffaith eu bod yn agos i'w gilydd, na fydd yn ei gwneud yn bosibl i'r mesur gael ei wireddu'n llawn.
English: Junction 41 eastbound, or eastbound and westbound on slip road closures do not achieve as great a reduction in concentrations as the Junction 41 westbound on slip only road closure would as a stand alone measure.
Welsh: Nid yw cau ffyrdd ymuno i'r dwyrain, neu i'r dwyrain ac i'r gorllewin yng Nghyffordd 41 yn arwain at ostyngiad mor fawr o ran crynodiadau ag y byddai cau ffordd ymuno yn unig i'r gorllewin yng Nghyffordd 41 yn ei wneud fel mesur annibynnol.
English: This measure has the potential to bring compliance and concentrations down by 3.5μg/m
Welsh: Gallai'r mesur hwn sicrhau cydymffurfiaeth a gostwng lefel y crynodiadau 3.5μg/m
English: A trial slip road closure of this junction was carried out previously by the Welsh Government in 2015.
Welsh: Cynhaliwyd ymarfer treialu cau'r ffyrdd ymuno/ymadael yn y gyffordd hon yn flaenorol gan Lywodraeth Cymru yn 2015.
English: The slip road closure was not implemented at that time due to the public feedback and other issues in the area, in particular the uncertain future of Port Talbot Steelworks.
Welsh: Ni chafodd y ffyrdd ymuno/ymadael eu cau ar y pryd oherwydd adborth gan y cyhoedd a materion eraill yn yr ardal, yn enwedig dyfodol ansicr gwaith dur Port Talbot.
English: Since 2015 and the trial closure, the diversion route that could be used has had a number of further developments constructed including a super school created following the closure of several local high schools.
Welsh: Ers 2015 a'r ymarfer treialu cau, mae nifer o ddatblygiadau eraill wedi cael eu codi ar hyd y llwybr gwyro y gellid ei ddefnyddio, gan gynnwys ysgol fawr a grëwyd ar ôl cau sawl ysgol uwchradd leol.
English: It is therefore deemed to be a precautionary retained measure until further work and discussion can take place with the local authority and stakeholders in the area.
Welsh: Felly, tybir ei fod yn fesur rhagofalus a ddargedwir nes bod modd gwneud rhagor o waith a chael trafodaethau gyda'r awdurdod lleol a rhanddeiliaid yn yr ardal.
English: It is also acknowledged that this measure is likely to be strongly resisted by local residents and the local authority.
Welsh: Cydnabyddir hefyd ei bod yn debygol y caiff y mesur hwn ei wrthwynebu'n gryf gan drigolion lleol a'r awdurdod lleol.
English: The Welsh Ministers therefore consider that the potentially significant time period required to investigate and implement the closure means that this measure would not reduce NO
Welsh: Felly, mae Gweinidogion Cymru o'r farn bod y cyfnod sylweddol o bosibl sydd ei angen i ymchwilio i gau'r ffyrdd ymuno/ymadael a rhoi hynny ar waith yn golygu na fyddai'r mesur hwn yn lleihau crynodiadau o NO
English: The variable diversions have been classed as a precautionary retained measure as it is expected that the rate of compliance with air quality limits is only marginally greater than with speed limits alone.
Welsh: Mae'r llwybrau gwyro amrywiadwy wedi cael eu dosbarthu'n fesur rhagofalus a ddargedwir oherwydd y disgwyl yw na fyddai'r gyfradd cydymffurfio â therfynau ansawdd aer ond ychydig yn well na'r gyfradd cydymffurfio gyda therfynau cyflymder ar eu pennau eu hunain.
English: As with the closures of the slip road and available diversion routes, this measure needs to be explored further to assess the impact with diverting the traffic close to the super school and the potential additional measures that this may require on the local road network.
Welsh: Fel yn achos cau'r ffordd ymuno/ymadael a'r llwybrau gwyro sydd ar gael, mae angen ystyried y mesur hwn ymhellach er mwyn asesu'r effaith o ran dargyfeirio'r traffig yn agos i'r ysgol fawr a'r mesurau ychwanegol posibl y bydd eu hangen o bosibl ar y rhwydwaith ffyrdd lleol.
English: Ramp metering has the potential to bring NO
Welsh: Gallai mesuryddion ramp leihau'r crynodiadau o NO
English: A previous design assessment has taken place of this measure and there is only one slip road that could be used for this operation, the Junction 41 eastbound on-slip.
Welsh: Mae asesiad dylunio o'r mesur hwn wedi cael ei gynnal yn flaenorol a dim ond un ffordd ymuno/ymadael y gellid ei defnyddio ar gyfer y gweithrediad hwn, sef ffordd ymuno i'r dwyrain yng Nghyffordd 41.
English: This slip road is sufficiently long enough to accommodate ramp metering without causing a concern with traffic backing back onto local roads.
Welsh: Mae'r ffordd ymuno hon yn ddigon hir i gynnwys mesuryddion ramp heb achosi pryder o ran traffig yn ciwio ar ffyrdd lleol.
English: However, the reduction cannot be achieved any sooner than with the speed limits alone and It is not proposed to consider this measure any further.
Welsh: Fodd bynnag, ni ellir sicrhau'r gostyngiad yn gynt na thrwy ddefnyddio'r terfynau cyflymder yn unig ac ni fwriedir ystyried y mesur hwn ymhellach.
English: The Welsh Ministers have taken the considered decision that the speed restrictions are the only measure that will achieve compliance with the NO
Welsh: Mae Gweinidogion Cymru wedi gwneud penderfyniad ystyriol mai cyfyngiadau cyflymder yw'r unig fesur a fydd yn sicrhau cydymffurfiaeth â'r gwerthoedd terfyn ar gyfer NO
English: Summary of WelTAG Stage 3 Action Plan
Welsh: Crynodeb o Gynllun Gweithredu Cam 3 WelTAG
English: The table below shows the measures to be implemented at the 5 exceedance locations, in respect of which there is reasonable scientific certainty that they will accelerate compliance with the limits set out in the Ambient Air Quality Directive (2008/50/EC) and the Air Quality Standards (Wales) Regulations 2010 in the shortest possible time.
Welsh: Mae'r tabl isod yn dangos y mesurau i'w rhoi ar waith yn y pum lleoliad lle ceir gormodiant, y mae sicrwydd gwyddonol rhesymol y byddant yn sicrhau cydymffurfiaeth â'r terfynau a nodir yn y Gyfarwyddeb Ansawdd Aer Amgylchynol (2008/50/EC) a Rheoliadau Safonau Ansawdd Aer (Cymru) 2010 cyn gynted â phosibl.
English: The subsequent table shows the PRM for the same 5 exceedance locations, in respect of which there is reasonable scientific certainty that they will accelerate compliance with the limits set out in the Ambient Air Quality Directive (2008/50/EC) and the Air Quality Standards (Wales) Regulations 2010 but not in the shortest possible time.
Welsh: Mae'r tabl dilynol yn dangos y mesurau rhagofalus a ddargedwir ar gyfer yr un pum lleoliad lle ceir gormodiant, y mae sicrwydd gwyddonol rhesymol y byddant yn sicrhau cydymffurfiaeth â'r terfynau a nodir yn y Gyfarwyddeb Ansawdd Aer Amgylchynol (2008/50/EC) a Rheoliadau Safonau Ansawdd Aer (Cymru) 2010 yn gynt ond nid cyn gynted â phosibl.
English: Action Plan measures by Exceedance Location
Welsh: Mesurau'r Cynllun Gweithredu yn ôl Lleoliad lle ceir gormodiant
English: PRM measures by Exceedance Location
Welsh: Mesurau Rhagofalus a Ddargedwir yn ôl Lleoliad lle ceir gormodiant
English: It is proposed that the current temporary orders made under section 14 of the Road Traffic Regulation Act 1984 will be revoked and replaced with orders made under section 84 of the Road Traffic Regulation Act 1984.
Welsh: Cynigir y bydd y gorchmynion dros dro presennol a wnaed o dan adran 14 o Ddeddf Rheoleiddio Traffig 1984 yn cael eu dirymu a'u disodli gan orchmynion a wneir o dan adran 84 o Ddeddf Rheoleiddio Traffig Ffyrdd 1984.
English: This will ensure that the limits can remain in force beyond 2019 where they are required.
Welsh: Bydd hyn yn sicrhau y gall y terfynau barhau mewn grym ar ôl 2019 lle mae eu hangen.
English: This is particularly necessary given the potential variance regarding the PCM data.
Welsh: Mae hyn yn gwbl angenrheidiol o ystyried y amrywiad posibl o ran data Mapio Hinsawdd Llygredd.
English: The 50mph speed limit on the M4 is implemented through the existing Variable Speed Limit order and as such can remain in place for as long as it is required.
Welsh: Mae'r terfyn cyflymder o 50mya ar yr M4 yn cael ei roi ar waith drwy'r gorchymyn Terfyn Cyflymder Newidiol ac fel y cyfryw gall barhau i fod ar waith cyhyd ag y bydd ei angen.
English: The Welsh Ministers anticipate that that the speed limits will remain in force for as long as they are required to maintain air quality standards.
Welsh: Mae Gweinidogion Cymru yn rhagweld y bydd y terfynau cyflymder yn parhau mewn grym cyhyd ag y byddant eu hangen i gynnal safonau ansawdd aer.
English: Accordingly, it is not possible to confirm the duration of the limits at this stage.
Welsh: Yn unol â hynny, nid oes modd cadarnhau am faint y bydd y terfynau yn para ar hyn o bryd.
English: It is expected that vehicle emissions will reduce as more new and cleaner vehicles come into use and older, more polluting vehicles become obsolete.
Welsh: Disgwylir y bydd allyriadau cerbydau yn lleihau wrth i fwy o gerbydau newydd a glanach gael eu defnyddio ac wrth i gerbydau hŷn, sy'n llygru mwy beidio â chael eu defnyddio mwyach.
English: However, the 50mph speed limits will be reviewed periodically to determine whether they are still necessary.
Welsh: Fodd bynnag, caiff y terfynau cyflymder o 50mya eu hadolygu o bryd i'w gilydd er mwyn cadarnhau p'un a oes eu hangen o hyd.
English: The WelTAG Stage 3 assessment has shown that 50mph speed limits are the optimal approach in all 5 locations.
Welsh: Mae asesiad Cam 3 WelTAG wedi dangos mai terfynau cyflymder o 50mya yw'r dull gweithredu gorau ym mhob un o'r pum lleoliad.
English: In addition, a Variable Diversion to encourage local traffic for Newport to leave the M4 prior to Junctions 25 and 26 when periods of high concentrations of NO
Welsh: Hefyd, Llwybr Gwyro Amrywiadwy i annog traffig lleol i Gasnewydd i adael yr M4 cyn Cyffyrdd 25 a 26 pan fydd cyfnodau o grynodiadau uchel o NO
English: Compliance with the 50mph speed limits is central to the effectiveness of the measures and enforcement of the speed limits is required to ensure the greatest compliance.
Welsh: Mae cydymffurfiaeth â'r terfynau cyflymder o 50mya yn ganolog i effeithiolrwydd y mesurau a bydd angen gorfodi'r terfynau cyflymder er mwyn sicrhau'r gydymffurfiaeth fwyaf.
English: Engagement with the Police is ongoing in respect of enforcement of the speed limits.
Welsh: Parheir i ymgysylltu â'r Heddlu o ran gorfodi'r terfynau cyflymder.
English: The Welsh Government has committed to providing the necessary funding and support to assist in this regard.
Welsh: Mae Llywodraeth Cymru wedi ymrwymo i ddarparu'r cyllid a'r cymorth angenrheidiol yn hyn o beth.
English: The attached timetable confirms the further work taking place along with key milestones when decisions are required on the precautionary measures.
Welsh: Mae'r amserlen a atodir yn cadarnhau bod rhagor o waith yn cael ei wneud ochr yn ochr â cherrig milltir allweddol pan fydd angen penderfyniadau ar y mesurau rhagofalus.
English: It is planned that work will continue with these precautionary retained measures in parallel to the monitoring.
Welsh: Y bwriad yw y bydd y gwaith hwnnw yn parhau a bydd y mesurau rhagofalus a ddargedwir yn cael eu cadw ochr yn ochr â'r gwaith monitro.
English: The effect of the measures on NO
Welsh: Mae effaith y mesurau ar grynodiadau o NO
English: The proposed measures outlined above are likely to achieve compliance with NO
Welsh: Mae'r mesurau a gynigir uchod yn debygol o sicrhau cydymffurfiaeth â'r gwerthoedd terfyn ar gyfer NO
English: Depending on the results of the onsite air monitoring, the "Precautionary Retained Measures" contained in the summary tables above may also have to be implemented to achieve ongoing compliance with the air quality limits.
Welsh: Yn dibynnu ar ganlyniadau'r gwaith monitro aer ar y safle, efallai y bydd angen rhoi'r "Mesurau Rhagofalus a Ddargedwir" a geir yn y tablau cryno uchod ar waith hefyd er mwyn parhau i sicrhau cydymffurfiaeth â'r terfynau ansawdd aer.
English: These precautionary retained measures will be subject to ongoing review using the Welsh Government monitoring put in place specifically for this purpose
Welsh: Caiff y mesurau rhagofalus a ddargedwir hyn eu hadolygu'n barhaus gan ddefnyddio gwaith monitro Llywodraeth Cymru a gyflwynwyd yn benodol at y diben hwn.
English: For WelTAG Stage 3, measures have been subdivided into 'hard measures' with tangible benefits on the network with reductions in concentrations being a direct consequence of the measure imposed and the soft or 'complementary measures' which could provide benefits at all 5 locations on the network, and potentially across the Welsh trunk road and motorway network as a whole.
Welsh: Ar gyfer Cam 3 WelTAG, mae mesurau wedi cael eu hisrannu'n 'fesurau caled' sy'n dwyn manteision diriaethol ar y rhwydwaith gyda gostyngiadau mewn crynodiadau yn deillio'n uniongyrchol o'r mesur a osodwyd a mesurau meddal neu 'ategol' a allai ddwyn manteision ym mhob un o'r pum lleoliad ar y rhwydwaith, ac o bosibl ledled rhwydwaith cefnffyrdd a thraffyrdd Cymru yn ei gyfanrwydd.
English: However, it is not possible to attribute any specific numerical reduction in NO
Welsh: Fodd bynnag, nid oes modd priodoli unrhyw ostyngiad rhifiadol mewn crynodiadau o NO
English: The complementary measures have therefore been included in all site-specific action plan packages going forward to implementation, but there has been no specific assessment of their impact.
Welsh: Felly, mae'r mesurau ategol wedi cael eu cynnwys ym mhob un o becynnau'r cynlluniau gweithredu ar gyfer y safle penodol sy'n cael eu rhoi ar waith, ond ni chafodd asesiad penodol o'u heffaith ei gynnal.
English: Whilst the direct benefits of the 'soft measures' are generally less than the 'hard measures', the 'soft measures' have little to no adverse impacts against other WelTAG impact areas, and so there is no reason not to universally include them in the WGSP.
Welsh: Er bod manteision uniongyrchol y 'mesurau meddal' yn llai na'r 'mesurau caled' ar y cyfan, nid yw'r 'mesurau meddal' yn cael fawr ddim effeithiau andwyol, os o gwbl, o gymharu â meysydd effaith WelTAG eraill ac felly nid oes unrhyw reswm dros beidio â'u cynnwys yn gyffredinol yng Nghynllun Atodol Llywodraeth Cymru
English: The set of 'soft measures' identified as the complementary package of measures are:
Welsh: Y gyfres o 'fesurau meddal' a nodwyd fel y pecyn ategol o fesurau yw:
English: Behaviour Change - implement a package of several measures aimed at changing travel behaviour, encouraging mode shift away from private car use.
Welsh: Newid Ymddygiad - rhoi pecyn o sawl mesur ar waith gyda'r nod o newid ymddygiad teithio, gan annog newid y dull gweithio oddi wrth ddefnyddio ceir preifat.
English: Intelligent Traffic Management* - linking real-time emissions / air quality data with traffic management, and / or remote monitoring through use of Intelligent Transport Systems and other innovative technological systems.
Welsh: Rheoli Traffig Deallus*, gan gysylltu allyriadau/data ansawdd aer amser real â rheoli traffig - a/neu fonitro o bell drwy ddefnyddio Systemau Trafnidiaeth Deallus a systemau technolegol arloesol eraill.
English: Signage - implement signage on the A483 to encourage better driving behaviour, reminding drivers to turn off their engine when stationary and emphasise awareness of other measures and/or awareness of entering an area of any special measures.
Welsh: Arwyddion - gosod arwyddion ar yr A483 er mwyn annog gwell ymddygiad gyrru, atgoffa gyrwyr i ddiffodd injan pan na fyddant yn symud a phwysleisio ymwybyddiaeth o fesurau eraill a/neu ymwybyddiaeth o fynd i mewn i ardal lle ceir unrhyw fesurau arbennig.
English: Air Quality Areas - use publicity campaigns and branding of areas to raise awareness of poor air quality within the area.
Welsh: Ardaloedd Ansawdd Aer - defnyddio ymgyrchoedd cyhoeddusrwydd a brandio ardaloedd er mwyn codi ymwybyddiaeth o ansawdd aer gwael yn yr ardal.
English: Air Quality Communications - implement a package of measures to generally raise awareness of air quality.
Welsh: Negeseuon ynglŷn ag Ansawdd Aer - rhoi pecyn o fesurau ar waith i godi ymwybyddiaeth o ansawdd aer yn gyffredinol.
English: * To complement the reduced speed limits, additional signs will be placed at the start of the reduced speed limit areas to relay the reasons for the speed limit reductions.
Welsh: * Er mwyn ategu'r terfynau cyflymder is, caiff arwyddion ychwanegol eu gosod ar ddechrau'r ardaloedd lle ceir terfyn cyflymder is er mwyn cyfleu'r rhesymau dros y cyfyngiadau terfyn cyflymder.
English: The complementary measures will initially be based on a significant communications campaign using social media, radio and signs on the network to highlight the air quality issues.
Welsh: Caiff y mesurau ategol eu seilio ar ymgyrch gyfathrebu sylweddol i ddechrau, gan ddefnyddio'r cyfryngau cymdeithasol, radio ac arwyddion ar y rhwydwaith i tynnu sylw at broblemau o ran ansawdd aer.
English: This campaign will be reiterated throughout the year at key periods when the air quality is measured to be at a high level from the roadside monitors.
Welsh: Caiff yr ymgyrch hon ei hailadrodd drwy gydol y flwyddyn ar adegau allweddol pan fydd y monitorau ar ymyl y ffordd yn mesur bod yr ansawdd aer ar lefel uchel.
English: There will also be regular updates and announcements provided on the air quality monitoring results at key stages over the coming years which should help reaffirm the messages and understanding of the issues.
Welsh: Hefyd, bydd diweddariadau a chyhoeddiadau rheolaidd ynglŷn â chanlyniadau monitro ansawdd aer ar gamau allweddol dros y blynyddoedd sydd i ddod a ddylai helpu i atgyfnerthu'r negeseuon a helpu pobl i ddeall y materion.
English: There are plans to launch a Wales wide schools competition.
Welsh: Bwriedir lansio cystadleuaeth i ysgolion ledled Cymru.
English: This competition will provide an opportunity for school children to design a symbol and sign that could be used at the 5 sites and provide further public awareness.
Welsh: Bydd y gystadleuaeth hon yn rhoi cyfle i blant ysgol ddylunio symbol ac arwydd a allai gael eu defnyddio ar y pum safle a chodi ymwybyddiaeth y cyhoedd ymhellach.
English: This will also help with furthering education on air quality issues.
Welsh: Bydd hyn hefyd yn helpu i addysgu pobl am faterion sy'n ymwneud ag ansawdd aer.
English: Next steps in relation to action being taken on the Welsh Government motorway and trunk road network to meet NO
Welsh: Y camau nesaf mewn perthynas â'r camau gweithredu sy'n cael eu cymryd ar rwydwaith traffyrdd a chefnffyrdd Llywodraeth Cymru i gyflawni'r terfynau cyfreithiol ar gyfer NO
English: The next steps are:
Welsh: Y camau nesaf yw:
English: Revoke and replace the current temporary orders to ensure that the limits can remain in force beyond 2019 where required;
Welsh: Dirymu'r gorchmynion dros dro presennol a'u disodli er mwyn sicrhau y gall y terfynau barhau mewn grym ar ôl 2019 pan fo eu hangen;
English: Implement additional signing at the sites on the A494, A483, A470 and M4 Port Talbot.
Welsh: Gosod arwyddion ychwanegol ar y safleoedd ar yr A494, A483, A470 a'r M4 ger Port Talbot.
English: The M4 Newport VSL already has electronic signs in place for speed limits;
Welsh: Mae arwyddion electronig eisoes wedi'u gosod ar gyfer terfynau cyflymder newidiol ar yr M4 ger Casnewydd.
English: To launch a communication campaign and take forward the complementary measures;
Welsh: Lansio ymgyrch gyfathrebu a rhoi'r mesurau ategol ar waith;
English: To launch a schools competition to educate children on air quality and look to badge the sites with a symbol to help raise awareness of the issues;
Welsh: Lansio cystadleuaeth i ysgolion er mwyn addysgu plant ar ansawdd aer ac ystyried gosod symbol ar y safleoedd er mwyn helpu i godi ymwybyddiaeth o'r materion;
English: To continue discussions and engagement with the Police regarding enforcement and education around the 50mph speed limits at the 5 locations;
Welsh: Parhau i drafod ac ymgysylltu â'r Heddlu o ran gorfodi ac addysgu mewn perthynas â'r terfynau cyflymder o 50mya yn y pum lleoliad;
