Refinery tight lipped following burn-off concerns
VALERO has refused to explain why their flare stacks at the Pembroke Oil Refinery were worryingly large on Friday night (Nov 16).
The Pembrokeshire Herald received several messages and photographs of the unprecedented burn-off from readers and concerned locals via social media and email.
An unconfirmed source at the refinery told this newspaper that there had been a problem with the alkylation de-isobutanizer – it ‘fell over’ our source said.
Alkylation is the process of producing gasoline range material such as propylene and butylene with isobutene – in the presence of a highly acidic catalyst, either sulphuric acid or hydrofluoric acid.
When asked to confirm the emergency burn off took place, and when asked if there was a serious malfunction, Stephen Thornton, Public Affairs Manager told us: “It is company policy not to comment on operations.”
When asked if he could deny that the incident occurred he again declined to comment.
A refinery expert told us: “The towers which have a constant burning flame is called a flare stack. In very simple terms, it is just like the burner of a gas stove with a controlled burning of natural gas through its pilot burners. It is the last line of safety or defence for refineries, petrochemical and gas processing plants.”
The expert went on: “The flare system consists of the flare stack and a flare header. A very large network of pipes coming from the different processes feed into the header. Whenever there is an upset or an emergency situation, all the extremely flammable hydrocarbons need to be vented out.
“But these cannot be just put in the atmosphere like the steam from our food pressure cookers. A vapour cloud would be extremely hazardous and catastrophic. To ensure that these escaping gases get burned to Carbon dioxide and water vapour, a flame is always kept burning on the top.
“Refinery operators generally see this as a necessary evil.
“The location of a fire stack is also very important. It is located far away from the main processing complex in the downwind direction.”
In April this newspaper reported that a potentially ‘catastrophic incident’ took place at Valero’s Pembroke Oil Refinery last year involving leaking gas and an ignition source
As previously reported, we were contacted earlier this year by a number of workers at the site who told us that it is only ’pure luck’ which prevented leaking gases from being blown into an ignition source, believed to be a furnace, which could have led to another lethal incident at the plant.
Valero have confirmed that they are working with statutory authorities who are investigating the event, which occurred on November 30 last year. It involved the Alkylate Iso-Stripper, which creates Alkylate – a premium component of petrol that has exceptional anti-knock properties and is clean burning.
The oil refinery’s management told us at the time that it is working with ‘continued co-operation’ with regulators, and highlighted in a statement that ‘no personnel were injured’ and that ‘there was no impact on the community’.
Valero, which says it is one of the leading employers in south Wales, added that they are unable to comment further during the period of investigation.
A Health & Safety Executive spokesperson told The Herald in a prepared statement: “We are aware of an incident at the Valero Energy Limited Pembroke Refinery in November 2017 which was reported to the Health and Safety Executive under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013).
“We can confirm that the incident took place on the Alkylate Iso-Stripper, and is being investigated.
“No enforcement action has been taken, though the investigation remains on-going.”

Craig Flannery appointed as new Chief Fire Officer
MID AND WEST WALES FIRE SERVICE LEADERSHIP CHANGE
MID and West Wales Fire and Rescue Service has announced the appointment of Craig Flannery as its new Chief Fire Officer, with effect from Monday, December 15, 2025.
Mr Flannery has served with the Service for more than twenty years, progressing through a wide range of middle management and senior leadership roles across both operational and non-operational departments.
During his career, he has been closely involved in strengthening operational delivery, risk management and organisational development. His work has included leading innovation in learning and development, overseeing the Service’s On-Call Improvement Programme, and driving investment in key enabling functions such as workforce development and information and communication technology.

The appointment followed a rigorous, multi-stage recruitment process led by Mid and West Wales Fire and Rescue Authority. Candidates were assessed through structured interviews, strategic leadership exercises and scenario-based assessments designed to test operational judgement, organisational vision and the ability to lead a modern fire and rescue service.
External professional assessors were also engaged to provide independent scrutiny, ensuring the process met high standards of fairness, transparency and challenge.
Mr Flannery emerged as the strongest candidate, demonstrating clear strategic leadership capability, detailed organisational knowledge and a strong commitment to community safety and service improvement.
Councillor John Davies, Chair of Mid and West Wales Fire and Rescue Authority, said: “Craig brings a deep understanding of our Service and a clear vision for its future. His appointment will strengthen our ability to innovate, support our workforce and deliver high-quality protection for the communities we serve.
“As we navigate a rapidly changing landscape, Craig’s experience in driving innovation and organisational development will be invaluable in helping us adapt and transform for the future.”
Commenting on his appointment, Mr Flannery said: “It is a privilege to lead this outstanding Service. I am committed to supporting our people, strengthening partnerships and building on the strong foundations already in place.
“As the challenges facing fire and rescue services continue to evolve, we must modernise and innovate, ensuring we have the skills, technology and capability needed to meet the needs of our communities. I look forward to working with colleagues and partners across Mid and West Wales to deliver a resilient, progressive Service that keeps people safe and places our staff at the heart of everything we do.”

Resident doctors in Wales vote to accept new contract
RESIDENT doctors across Wales have voted to accept a new contract, with 83% of those who took part in a referendum backing the agreement, according to BMA Cymru Wales.
The contract includes a four per cent additional investment in the resident doctor workforce and introduces a range of reforms aimed at improving training conditions, wellbeing and long-term workforce sustainability within NHS Wales. The BMA says the deal also supports progress towards pay restoration, which remains a central issue for doctors.
Key changes include new safeguards to limit the most fatiguing working patterns, measures intended to address medical unemployment and career progression concerns, and reforms to study budgets and study leave to improve access to training opportunities.
Negotiations between the BMA’s Welsh Resident Doctors Committee, NHS Wales Employers and the Welsh Government concluded earlier this year. Following a consultation period, a referendum of resident doctors and final-year medical students in Wales was held, resulting in a clear majority in favour of the proposals.
Welsh Resident Doctors Committee chair Dr Oba Babs Osibodu said the agreement marked a significant step forward for doctors working in Wales.
He said: “We’re proud to have negotiated this contract, which offers our colleagues and the future generation of doctors safer terms of service, fairer pay, and better prospects so that they can grow and develop their careers in Wales.
“This contract will help to retain the doctors already in training, and also attract more doctors to work in Wales, where they can offer their expertise and benefit patients.”
Dr Osibodu added that the BMA remains committed to achieving full pay restoration and acknowledged that challenges remain for some doctors.
“Whilst this contract sets the foundations for a brighter future for resident doctors in Wales, we recognise that there are still doctors who are struggling to develop their careers and secure permanent work,” he said. “We need to work with the Welsh Government and NHS employers to address training bottlenecks and underemployment.”
The Welsh Government has previously said it recognises the pressures facing resident doctors and the importance of improving recruitment and retention across NHS Wales, while also highlighting the need to balance pay agreements with wider NHS funding pressures and patient demand.
The new contract is expected to be phased in from August 2026. It will initially apply to doctors in foundation programmes, those in specialty training with unbanded rotas, and new starters, before being rolled out to all resident doctors across Wales.

Swansea man jailed for online child sex offence dies in prison
A SWANSEA man who was jailed earlier this year for attempting to engage in sexual communication with a child has died while in custody.
Gareth Davies, aged 59, of the Maritime Quarter, was serving an 18-month prison sentence after being convicted in May of sending sexually explicit messages to what he believed was a 14-year-old girl. The account was in fact a decoy used as part of an online safeguarding operation.
The court heard that Davies began communicating with the decoy between November and December 2024 and persistently pursued the individual, later attempting to arrange a face-to-face meeting. He was arrested after being confronted by the decoy operators.
Davies had pleaded not guilty but was convicted following a trial. At the time of sentencing, police described the messages as extremely concerning and said his imprisonment was necessary to protect children.
It has now been confirmed that Davies died at HMP Parc on Wednesday (Nov 27) while serving his sentence.
The Prisons and Probation Ombudsman has launched an independent investigation into the death, which is standard procedure in all cases where someone dies in custody. No cause of death has been released at this stage.
A coroner will determine the circumstances in due course.
