Valero Oil Refinery came close to ‘catastrophic incident’

EXCLUSIVE REPORT

A POTENTIALLY ‘catastrophic incident’ took place at Valero’s Pembroke Oil Refinery last year involving leaking gas and an ignition source, the Pembrokeshire Herald can reveal.

This newspaper has been contacted by a number of workers at the site who have 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 Iso-Stripper is a high risk area of refining, and uses either sulphuric acid or hydrofluoric acid as a catalyst for its chemical reactions.

The oil refinery’s management told The Herald 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.

HSE INVESTIGATES

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 ongoing.”

PUSHING THE PLANT HARDER

Our sources working at the refinery told The Pembrokeshire Herald, on condition of anonymity, that the incident last year was due to the refinery being pushed harder than before. This, combined with the ageing infrastructure at the site, lead to the close call.
He told us: “They have increased output which puts more strain on the equipment.”
Another employee at the site, who also did not wish to be named, confirmed this. He said that since the refinery was bought from Chevron, it is being stretched and running 20-30% harder than before.
This, combined with a lack of maintenance, is making it an ‘accident waiting to happen’, he added.

RECENT LEAK OF GAS

Valero confirmed that last month’s activation of emergency sirens was in response to another leak of gas at the plant. But it is not currently known from which part of the refinery.
Readers contacted The Pembrokeshire Herald by telephone and social media on the morning of March 29 concerned after hearing a warning sound, which started at exactly 8.01am.
On contacting the refinery the Herald was initially told by a security worker: “We have no information at the moment, we are not sure if it’s a test or not.”
Looking to clarify his answer, our reporter asked: “So you are not sure if it’s a test or a real emergency?”
The Herald was told: “That’s right”
It is understood that there was confusion due to previous false alarms.
Later this newspaper received a statement from Valero spokesperson and Refinery Public Affairs Manager, Stephen Thornton, who said: “At 8:00 am on 29th March 2018, the alarm sounded on site due to identification of a minor gas leak.
“Operations responded promptly to isolate and de-pressure the line to stop the leak.”

SAFETY A ‘GUIDING PRINCIPLE’

In a statement prepared by Valero for The Pembrokeshire Herald, the company said: “Safety is the guiding principle for all that we do at Pembroke Refinery, and Valero takes strong exception to any suggestions otherwise. As one of Europe’s largest and most complex refineries, our highly skilled workforce at Pembroke Refinery operates according to comprehensive and rigorous management systems and standards of safety.

“Valero does not comment on operational activities at Pembroke Refinery, however all our activities are conducted within approved regulatory permit limits. All refinery work is undertaken according to stringent regulatory, industry and company standards that ensure the continued effective integrity of the plant, regardless of working capacity. Our advanced and sophisticated operational, inspection and maintenance procedures at the refinery are underpinned by a safety culture fostered across all our personnel, focused on recognising and eliminating hazards before they occur.
“In addition to our own focus on safety, Valero also actively works alongside public bodies such as the Health and Safety Executive, emergency services, the local authority and other agencies to manage risk. This includes Valero’s continued cooperation with regulators regarding an ongoing investigation into an event that occurred in November 2017. No personnel were injured during this incident and there were no impacts on the community, however we are unable to comment further during this investigation.
“Anyone making enquiries regarding Valero’s operations, including our site alarm system, should ask to speak to a member of Valero’s Policy, Government & Public Affairs Department.
“All calls received at the refinery are dealt with by our dedicated security team who follow protocol of not confirming refinery operational details, but will pass your details on if requested.”

OIL REFINING – A HAZARDOUS ENTERPRISE

Refinery fire: 2011 accident tragically claimed four lives

It is not the first time that Valero have had the safety of their workplace questioned, nor the first time an incident has affected the Pembroke refinery.
Valero were fined £400,000 at Swansea Crown Court after an incident involving a walkway collapsing and an employee left hanging from ropes at their refinery in Pembroke. It was found that Valero, the American oil company which purchased the Pembroke site in a £447m deal in March 2011, failed to follow procedure and carry out a comprehensive risk assessment on the access tower of which the gangway collapsed seriously injuring a worker.
It was said in court that the maintenance contractor of Valero had their suggestions ignored over the potential risks of the access tower, as they raised the point that there was a ‘potential fatal accident waiting to happen.’ Valero were also seen to give inadequate training and instructions to employees, regarding the safe operation of the tower and gangway.
The incident took place on March 5 2012, as David Thomas, an operator at the refinery, was making his way towards an unloading oil tanker via the gangway of the access tower. The walkway suddenly collapsed and he was dropped 3.5 metres. Mr Thomas, 55, was left swinging from wire rope that had wrapped round his legs, but, as a keen rock climber, was able to distribute the weight from his legs by gripping a cross beam. Despite this, he suffered a dislocated knee as well as lacerations and fractures. Mr Thomas was released from hospital after 17 days, but soon developed arthritis, and ultimately didn’t return to work.
It was deemed that three other related incidents at the refinery previous to the gangway accident, in August 2010, February 2011 and September 2011, were poorly investigated and that a proper checklist assessment was not carried out.
At the time of the infamous explosion in June 2011, which resulted in four fatalities, the refinery was still operated by Chevron, yet the deal to sell the refinery to Valero had already been organised. In November 2015, the Crown Prosecution Service ultimately decided against pressing charges of corporate manslaughter.

Begelly man sentenced for carrying metal bar during nightclub fight

A MAN has been sentenced after approaching a Pembrokeshire nightclub armed with a metre-long metal bar.

Just after 2:30am on July 21, police were called to Main Street, Pembroke, following reports of a large fight involving around 100 people outside ‘Out’ nightclub.

Crown Prosecutor Nia James told Haverfordwest magistrates this week: “Officers were told it was a large fight. They saw Walter Probert, 27, march purposefully towards a parked van.

“The van’s lights were on, and they saw the defendant pull out a long, green metal pole. He took ten steps back towards the nightclub and transferred the pole from one hand to the other.”

Another man approached Probert, removed the pole from his hands, and placed it inside the van.

“Because of the manner in which the pole was used by the defendant, it became an offensive weapon,” added Ms James.

CCTV footage of the incident was shown to magistrates.

Probation officer Julie Norman said Probert had no recollection of the incident.

“He doesn’t remember what he was doing, but he accepts everything that has been said. He was very drunk,” she said.

“He was brought up in the gypsy travelling community and doesn’t have an alcohol issue; he’s just a social drinker. He’s thankful to his friend who took the pole and placed it back inside the van.”

Probert, of the Caravan Site, Kingsmoor Common, Begelly, pleaded guilty to possessing an offensive weapon in a public place. He was represented in court by Mr Tom Lloyd.

“No threats were made by the defendant when he picked it up, but it was a stupid decision,” said Mr Lloyd. “As soon as he was challenged and asked what he was doing, he ceased.”

Probert was sentenced to a 12-month community order, requiring him to carry out 150 hours of unpaid work. He was also ordered to pay £85 costs and a £114 court surcharge. Magistrates imposed a destruction order on the metal bar.

Police close Westfield Pill Bridge over concerns for person’s welfare

FEARS for a person’s safety led police to close Westfield Pill Bridge, near Neyland.

The bridge, on the A477 between Honeyborough roundabout and the Cleddau Bridge, was shut for just over an hour, with drivers advised to seek alternative routes.

The incident took place on Friday evening and was concluded when the person was located safe and well.

A Dyfed-Powys Police spokesperson said: “Dyfed-Powys Police received a call for a concern for the welfare of an individual on Westfield Pill Bridge at around 7:30pm on Friday, December 20.

“The road was closed and reopened at around 8:40pm.

“The individual was located safe and well.”

This is not the first time such an incident has led to a bridge closure.

There have been several previous similar incidents, including on Friday, October 4, 2024, the Cleddau Bridge was closed for about an hour following a call reporting a welfare concern. The closure occurred at around 4:45pm, and the bridge reopened at 5:45pm.

The person involved was taken to the hospital for treatment.

In June, a multi–agency rescue operation unfolded at Neyland Marina after a youth jumped approximately 40 metres from Westfield Bridge into the water below.

Emergency services, including crews from Mid and West Wales Fire and Rescue Service (MAWWFRS) stations in Haverfordwest, Milford Haven, Pembroke Dock, and Carmarthen, were swiftly dispatched to the scene.

According to a spokesperson for MAWWFRS, members of the public were instrumental in rescuing the youth before the arrival of the emergency crews.
