Diolch. Rwy'n deall fod Dŵr Cymru wedi bod yn ymchwilio i orlifoedd cyfunol sy'n gollwng llawer yn Afon Tawe fel rhan o'u hymchwiliadau i fframwaith asesu gorlif stormydd, a'u bod yn buddsoddi cyllid sylweddol - rwy'n credu ei fod dros £100 miliwn - i uwchraddio eu rhwydwaith rheoli gwastraff. Hefyd, mae Cyfoeth Naturiol Cymru a Chyngor Abertawe wedi bod yn gweithio ar leihau camgysylltiadau domestig, lle mae cartrefi neu fusnesau yn cysylltu eu systemau carthion yn anghywir â'r prif rwydwaith carthffosydd. Mae hynny, yn amlwg, mewn cydweithrediad â Dŵr Cymru hefyd.

Thank you. I do understand that Dŵr Cymru Welsh Water have been investigating high-spilling combined overflows in the River Tawe as part of their storm overflow assessment framework investigations, and that they are investing significant funding - I think it's over £100 million - to upgrade their wastewater management network. Also, Natural Resources Wales and Swansea Council have been working on reducing domestic misconnections, which is where households or businesses incorrectly connect their sewage systems to the main sewer network. That's, obviously, in collaboration with Dŵr Cymru Welsh Water as well.

Wel, mae'n wych pan fydd plant yn cael yr ysgolion newydd hynny, ond mae yna lawer gormod o blant sy'n cael eu haddysgu mewn adeiladau annigonol a pheryglus. Canfu arolwg barn diweddar ledled y DU fod 90 y cant o athrawon yn credu bod ysgolion sydd wedi'u hadeiladu a'u cynllunio'n dda yn gwella canlyniadau addysgol. Felly, mae gennym ddyletswydd i sicrhau bod ein plant yn cael eu haddysgu mewn adeiladau nad ydynt yn niweidio eu haddysg neu eu hiechyd, waeth beth fo'r cyfyngiadau ar y gyllideb.

Well, it's fantastic when children have those new schools, but there are still way too many children who are being educated in inadequate and dangerous buildings. A recent UK-wide poll found that 90 per cent of teachers believe that well-built and designed schools improve educational outcomes. So, we have an obligation to ensure that our children are educated in buildings that do not harm their education or their health, regardless of budget constraints.

Mae ffordd ddosbarthu'r cyrion ym Mhort Talbot, a agorwyd i leddfu galw traffig lleol ar yr M4, wedi bod yn weithredol ers oddeutu tair blynedd bellach. Pa ddata y mae Llywodraeth Cymru wedi'i gael gan yr awdurdod lleol, neu wedi'i dynnu o waith y Llywodraeth ei hun yn ystod arbrawf cyffordd 41, ynglŷn â newidiadau i symudiadau traffig ac ansawdd aer yn benodol? A allwch ddweud wrthyf pa newidiadau parhaol a nodwyd o ran ansawdd aer ac a yw'r rheini'n dylanwadu ar eich penderfyniad terfynol ynglŷn â'r hyn a fydd yn digwydd i gyffordd 41?

The Port Talbot peripheral distributor road, opened to relieve local traffic demand on the M4, has been operational for about three years now. What data has the Welsh Government received from the local authority, or extracted from its own work during the junction 41 experiment, about changes to movements of traffic and air quality in particular? Can you tell me what permanent changes have been identified to air quality and are those influential in your final decision on what's going to happen to junction 41?

A'r cwestiwn olaf gen i ar y foment ydy: allaf i jest gofyn pa ddarpariaethau yn y Bil y gellid eu gwneud gan Weinidogion Cymru, gan ddefnyddio'u pwerau presennol, i wneud Gorchmynion o dan Ddeddf Llywodraeth Cymru 2006? Hynny yw, pam ei bod hi'n briodol i chi fel Comisiwn ddod â'r ddeddfwriaeth yma gerbron, yn hytrach na jest gadael i Weinidogion Cymru ddefnyddio'r cymhwysedd gweithredol sydd ganddyn nhw eisoes?

And the final question from me, for the moment, is: what provisions in the Bill could be made by the Welsh Ministers, using their existing Order-making powers, under the Government of Wales Act 2006? Why do you consider it appropriate for you as a Commission to be bringing these provisions forward, as opposed to letting the Welsh Ministers to do so, using their existing executive competence?
