Petroplus must empty a second tank at its Milford haven site

Petroplus has been told it must drain and check the large container at its site near Milford Haven.

People close to Hazelbeach are still living with the fall-out from the 600 tonne spillage last month.

The beach remains closed and there are concerns about domestic water supplies as people have complained of head and stomach aches.

The source of the leak on 2 August was traced to tank T115 at the site.

On Friday the Environment Agency issued a second suspension notice that requires Petroplus to drain and inspect nearby tank T114 although it said it was just a precautionary measure.

The recovery operation will be on-going for some time

It said it was still gathering evidence surrounding the spillage.

The agency's Jed Davies said the leak had affected the beach and signs advising people not to walk their dogs there or collect shellfish were still in place.

"We are still investigating and there are potentially a number of offences. It's a question of going through all the evidence. It will take some time to complete," he said.

"I'm not aware that there has been any oil on the beach for sometime but the signs remain as a precaution.

"The recovery operation is still on-going and it's likely to be on-going for some time."

He said wildlife had been affected with some swans moved from the area for treatment.

Drinking water at homes in the nearby village of Llanstadwell is being monitored after a false alarm this week that the supply to one house had been contaminated.

Petroplus has joined with Welsh Water, Pembrokeshire Council and other local bodies to deal with the incident.

A spokesman for the taskforce said on Friday: "We took the precaution of isolating the supply to the affected property whilst we carried out sampling.

"No other properties in the village have reported similar problems, however we will continue to monitor the situation over the coming weeks."

But Dr Lyn Harris, public health director for the Pembrokeshire Local Health Board, said there was no evidence to suggest that the level of kerosene released into the environment posed a risk to human health.
