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.”

Calls grow for independent investigation into Manorbier school closure
Councillor alleges misleading figures, inadequate insurance and poor treatment of staff
CALLS for an independent investigation into the controversial closure of Manorbier Church in Wales VC School are gathering pace ahead of a full council meeting next week.
Local member Cllr Phil Kidney has submitted a Notice of Motion calling for a full and impartial inquiry into the way Pembrokeshire County Council handled the closure process.

The proposed investigation would examine the length of time taken, alleged broken promises, insurance arrangements and the involvement of the council’s Human Resources department.
Cllr Kidney says the review should be carried out by someone who is not employed by the authority and should have the power to recommend disciplinary action where appropriate.
He said: “A full impartial review should hopefully stop another school being treated so appallingly.”

The call has now been backed by Milford Haven Hakin Reform councillor Scott Thorley, who launched a strongly worded attack on the authority’s handling of the school.
Writing on Facebook, Cllr Thorley said: “The council’s treatment of this school is shocking. Misleading figures, manufactured pupil numbers, totally inadequate insurance and the worst thing was the treatment of the staff.”
The claims have not yet been independently established, but they add to growing pressure on the council to explain how the school’s closure was handled and why the fire-damaged building was not fully reinstated.
Manorbier School and the adjoining schoolhouse were severely damaged by fire in October 2022, with pupils subsequently moved to a temporary “school from school” at Jameston Village Hall.
Although campaigners had hoped the original school would be rebuilt, councillors later backed a statutory process to discontinue it.
The proposal attracted strong opposition, with more than 1,500 people signing a petition calling for the school to be rebuilt and more than 90 per cent of consultation respondents opposing closure.
At a special meeting on June 15, councillors voted by 30 votes to 23, with four abstentions, to proceed with the final steps towards closure.

The Diocese of St Davids also opposed the decision and warned that legal action, including judicial review, could follow.
Questions remain over the insurance cover in place at the time of the fire, the true cost of rebuilding or closing the school, disputed pupil and surplus-place figures, and the treatment of staff during the process.

Pembrokeshire County Council has previously said the Leader has asked the Governance and Audit Committee to review the authority’s insurance position.
Cllr Kidney is also seeking an apology from Cllr Paul Miller, the council’s deputy leader and Cabinet Member for Education.
He has asked whether Cllr Miller will apologise to staff and parents for comments made at the June meeting, including claims that children would receive a better education at St Florence and that Manorbier pupils were being taught in one room.
Cllr Kidney described those comments as factually wrong and insulting to staff who had worked to maintain education standards after the fire.
Both the motion for an investigation and the request for an apology are due to be considered when full council meets on Thursday (Jul 16).

Memorial bench unveiled in honour of former councillor Mike Stoddart
AN EMOTIONAL gathering was held at Hubberston and Hakin Community Centre as family, friends and volunteers came together to remember the late Mike Stoddart last week.
Members of Mike’s family joined Community Centre trustees and volunteers to commemorate a memorial bench installed in the centre’s Memorial Garden.
Mike, affectionately known as “Old Grumpy”, died on January 4, 2026, aged 85.
Alongside his many years of service as the county councillor for Hakin, Mike was also a dedicated trustee of the Community Centre and worked tirelessly on behalf of local residents.

The inscription on the bench describes it as “a place to sit and remember” and recognises Mike’s contribution as a centre trustee.
The Community Centre said it had been an emotional but special evening and thanked everyone who attended to pay tribute.
Similar memorials are also being planned to honour the late Eric Harries and John Morgan, recognising their own service and contribution to the community.

Fire service issues safety warning as extreme heat raises wildfire risk
MID AND WEST WALES FIRE AND RESCUE SERVICE is urging residents and visitors to take extra care as extreme heat and prolonged dry conditions increase the risk of wildfires and water-related emergencies.
The warning follows the issuing of a red extreme heat alert for parts of Wales, with exceptionally high temperatures forecast and emergency services preparing for added pressure in the days ahead.
Fire chiefs say the hot, dry weather has left grassland and vegetation particularly vulnerable, meaning even a small spark could develop into a fast-moving countryside fire.
Aled Griffiths, Head of Community Safety for Mid and West Wales Fire and Rescue Service, said: “With very high temperatures forecast across Wales this week, it’s important that we all take extra care to stay safe and reduce avoidable risks.
“We want everyone to enjoy the sunshine, but these conditions can increase the likelihood of incidents, including fires and water-related emergencies.
“Small actions can make a big difference, whether that’s using barbecues safely, disposing of smoking materials responsibly or taking extra care around open water.”

Barbecue and outdoor fire safety
Anyone using a barbecue is being advised to place it on a flat, non-combustible surface, well away from buildings, fences, dry grass and shrubs.
Barbecues should never be left unattended and must be completely extinguished and allowed to cool before ashes are disposed of.
The public is also being asked not to light campfires or other open fires, particularly in rural areas where dry vegetation can allow flames to spread rapidly.
Cigarettes, matches and glass bottles should never be discarded in the countryside.
The fire service has also reminded residents that burning grass or garden waste is prohibited at this time of year.
Open water warning
The hot weather is also expected to encourage more people to swim in lakes, rivers, reservoirs and other open water.
However, the fire service warned that water temperatures can remain dangerously cold even during periods of extreme heat.
Cold water shock can cause an involuntary gasp, rapid breathing, panic and a sudden loss of swimming ability, significantly increasing the risk of drowning.
People are advised never to jump or dive into unfamiliar water and not to enter open water after drinking alcohol.
Float to Live
Anyone who gets into difficulty in the water should:
- Tilt their head back, keeping their ears submerged
- Relax and try to breathe normally
- Move their hands and legs gently to remain afloat
- Avoid panicking if their legs begin to sink
Once breathing is under control, they should call for help or attempt to swim to safety.
The fire service recommends practising floating in a supervised environment, such as a swimming pool.
Phone, Float, Throw
Anyone who sees another person in difficulty should remain on land and follow the Phone, Float, Throw advice:
- Phone 999 and ask for the emergency services
- Encourage the person to remain calm and float on their back
- Throw rescue equipment or another floating object towards them
Members of the public should not enter the water themselves, as this can place both people in danger.
Further wildfire and water safety advice is available through Mid and West Wales Fire and Rescue Service’s website and social media channels.
