I thank the Cabinet Secretary for her statement this afternoon, and also for the telephone conversation that we had early on Friday morning and her willingness to visit the area on Saturday afternoon. She mentioned that she was content with the speed of the response, but may I ask for a little more information about the timetable? When exactly was NRW informed by the company of the reduction in pressure in the pipeline? When did NRW staff visit the site on the first occasion? When did they decide that the spill was more serious? When was the pipeline closed? And when did the remaining oil in the pipeline cease to leak further?

The isolation valves were closed, according to the information that I have, in the Llandeilo and Llangain areas. Can the Cabinet Secretary explain why the valve that is apparently closer to the area of Nantgaredig was not closed, which could have perhaps prevented tens of thousands of litres of oil from being leaked?

Does the Cabinet Secretary agree that we need a full inquiry into the cause of this unfortunate incident? Can she also confirm that NRW’s powers include the right to bring prosecutions if there is evidence of malpractice? When, for example, was the last time that this pipeline was inspected? And, of course, this company is a company with an income of £4 billion per annum, so can we be given an assurance that it will pay compensation to local residents and farmers affected by this?

Has the pipeline been registered under the Pipelines Safety Regulations 1996, and if not, why?

Ac yn olaf, o ran mater yr A48, bydd hi’n gwerthfawrogi a chyfeiriwyd at hyn eisoes, wrth gwrs, yr effaith y bydd hyn yn ei chael yn lleol ar drigolion sydd eisoes yn gorfod ymdopi, nos Wener, er enghraifft, â chau’r ffordd i un cyfeiriad—effaith ddifrifol. A ystyriwyd yr holl ddewisiadau eraill yn y fan yma o ran y gwaith adfer sydd angen ei wneud ar y biblinell? Rydym wedi clywed, er enghraifft, na fydd y gwaith yn cael ei wneud dydd a nos. Does bosib na ddylem ni ystyried hynny cyn cau yr hyn sydd, wedi'r cyfan, yn brif wythïen i’r gorllewin cyfan i’r ddau gyfeiriad. Felly, a yw hi'n fodlon bod yr holl ddewisiadau eraill wedi eu hystyried, ac a wnaiff hi gadarnhau bod o leiaf un o'r asiantaethau perthnasol wedi gwrthwynebu'r cynnig mewn gwirionedd i gau'r ffordd i’r ddau gyfeiriad pan gafodd hynny ei gynnig iddynt i ddechrau?
