Proposals to drill exploratory oil and gas wells near Dunsfold in Surrey have been published – but there are already calls for the application to be put on hold because of inconsistencies in the information.
The application, submitted by UK Oil & Gas plc (UKOG), comprised 85 documents.
Surrey County Council validated the application on 28 May 2019, which means officials were happy that the information was complete and in the correct format.
But DrillOrDrop understands that the council has been asked to suspend consideration of the application while the inconsistencies are addressed.
We asked UKOG and Surrey County Council to comment on the inconsistencies. The council said:
“The application was valid on 28 May 2019, when all the necessary paperwork was complete. The statutory period for determination is 13 weeks. However on such an application the determination period is likely to be extended during the consultation process when further information is required.
“We have not received any requests to suspend the determination of this application.”
Two maps submitted as part of the application show different routes for the access track.
The executive summary of the waste management plan (extract left) includes some identical paragraphs to the equivalent submitted for the application for long-term oil production at the Horse Hill site currently before the council (extract right).
One paragraph in both summaries refers to:
“the waste streams identified are consistent with those that were encountered during the original development, which consisted of well site construction, drill operations and well testing operations”.
But the Dunsfold proposal is on a greenfield site where no previous oil development has taken place. The planning statement says:
“The Site has no planning history; the land has an historic agricultural use”
National planning policy
The application’s planning statement refers three times to a paragraph in the National Planning Policy Framework (209a) which was struck out in March 2019 by a High Court judge.
Mr Justice Dove ruled that the paragraph, which required councils to recognise the benefits of onshore oil and gas, was unlawful because of failings in a government consultation.
Last month, the local government secretary, James Brokenshire, acknowledged that paragraph 209(a) of the framework had been quashed.
The transport plan for the Dunsfold application states that vehicles coming to the proposed site from the south and west would follow the A272 from Petersfield to Billingshurst.
The plan does not mention that this would take heavy goods vehicles through the centres of Midhurst and Petworth.
The Petworth neighbourhood plan, approved by the South Downs National Park Authority in July 2018, said:
“the nature of the historic town centre makes it entirely unsuitable for heavy goods vehicles which continue to cause damage to buildings and measures are required to direct them elsewhere.”
Previous planning errors
This is the second time that problems have been identified with a UKOG planning application.
In 2017, objectors criticised the quality of the application for exploratory drilling at Broadford Bridge in West Sussex.
The waste management plan for that site also referred incorrectly to the Horse Hill site.
There were inconsistencies between the waste management plan and the safety data sheet.
The health and safety management plan for Broadford Bridge said serious casualties resulting from an accident or emergency would go to Horsham Hospital – but there was no accident or emergency department at the hospital.
Key facts on the Dunsfold application
These details are from the UKOG application to Surrey County Council. There are currently no details on the opening or closing dates for a public consultation.
DrillOrDrop will follow the progress of the application through the planning system.

The planning application made the following conclusions on the effects of the development:
Impacts on landscape and trees: “negligible or minimal”
Risk to groundwater and flooding: “not significant” and could be made acceptable.
Ecological sites: No adverse effects
Greenhouse gases: Releases would be considered “insignificant” to the UK’s current and future budgets
Major accident or disaster: the site was “sufficiently remote from land-use hazards to render any risk unlikely and not major”.
Earthquakes: the site would “not contribute to a seismic event”
Traffic emissions: “neutral impact” on air quality, the company said.
Choice of site
UKOG said its site identification report concluded that the proposed site was the best environmental option and the most sustainable solution.
The planning statement concluded that the proposed development achieved “a high degree of compliance” with local planning policies. It also drew “strong support” from government policy, it said.
The document concluded:
“Planning permission should be consented without delay.”
