Fracking (shale gas)

Westerdale by Chris CeaserWesterdale by Chris Ceaser


November 2017 – INEOS Shale UK, the company with several Oil & Gas exploration (PEDL) licences along the southern edge of the National Park and Northern edge of the Yorkshire Wolds (south of Malton) have approached the Authority to advise that, in 2018, they are to commence public consultation events to explain their exploration intentions in respect of their local licenses after their current exploration programme in Derbyshire and Rotherham. These will start in the Yorkshire Wolds (south of Malton) and then be followed by the southern edge of the North York Moors Local Plan. Details will be published in the local Press nearer the time and we will aim to publish them on this webpage.

The NPA welcomes the Government’s intention to prohibit any surface development required for hydraulic fracturing within National Parks as this increases the protection afforded to these special areas (DECC Consultation 4 Nov 2015). However, the Regulations voted on today (16 December 2015) which allow fracking to occur below 1200m from drilling outside the boundary of a National Park undermine this intention and indeed the legislation protecting these areas, which do not stop at a certain depth below the surface.

The Authority understands the Government’s wish to proceed with the shale gas industry as a transitional approach to help to move towards a lower carbon energy strategy whilst also demonstrating to the public that the country’s most sensitive environments would be protected from the risks associated with fracking. However, the fact that fracking itself will still be able to take place in the geology of the National Park means that public concerns surrounding potential groundwater contamination, seismic activity and faulting and the use of chemicals and release of naturally occurring radiative material do not appear to be addressed.

In cases where there may be future proposals for lateral fracking to extract shale gas beneath the North York Moors, the Authority would assess such a planning application against the government policy known as the ‘Major Development Test’. This does not allow such development in National Parks unless there are exceptional circumstances which must demonstrate that there is a national need for the development and that it can’t take place outside the designated area. As the Minerals Planning Authority the NPA therefore has strong planning powers to assess whether to allow future proposals for lateral fracking.

Jim Bailey, Chair of National Parks England said: 

“Today’s decision to protect National Parks from surface works is welcome; and we think it is now essential that the Government’s National Planning Policy Framework is amended to make it crystal clear that hydraulic fracturing is not allowed in National Parks.  The public want to see the highest level of protection for National Parks, and so works located close by but that might involve drilling underneath National Parks must be subject to the most rigorous testing.  These sensitive areas should be the last, not the first place that developers should prospect.”

The following information on fracking is provided in response to growing public interest on the subject in and around the National Park. The North York Moors National Park Authority is the minerals planning authority for the National Park and will be responsible for determining any planning applications for fracking.

What is fracking?

Fracking is the common term for hydraulic fracturing, a process which involves high pressure injection of water, sand and chemicals through a borehole into deep shale rock causing this to crack and release gases (mostly methane). A vertical borehole is required to inject the sand, water and chemicals to significant depths below the surface where the fracking would take place. The gas which is extracted flows back through the borehole to the surface where it could either be used to generate electricity or be fed into gas supply networks. Waste water also returns to the surface through the borehole and this would need to be treated. Further details on the fracking process can be found here.

Is fracking currently taking place in the North York Moors National Park?

No. To date there has not been any commercial interest in fracking within the North York Moors National Park. Conventional forms of gas exploration and production have taken place in and around the National Park over recent decades, particularly in the south west of the Park and around Westerdale.

Is there shale gas under the North York Moors National Park?

A report produced by British Geological Survey suggests that the geology beneath the southern part of the North York Moors National Park may contain commercially viable shale gas resources. The British Geological Survey report suggests that shale rock which may be suitable for fracking is likely to exist between 1,500 and 4,000 metres below the surface of the National Park.

What is the National Park Authority’s current policy on fracking?

Whilst the Authority does not currently have any planning policies relating specifically to gas or fracking, a number of the policies contained in the Core Strategy and Development Policies would be relevant to determining applications for fracking. Within the National Park particular consideration would be given to the impacts on the Park’s special qualities and fracking applications may also be subject to consideration under the Major Development Test whereby the presumption is for refusal except in exceptional circumstances and where the development can be demonstrated to be in the public interest.

The Authority is developing policies to assess proposals for gas extraction, including fracking, as part of the Minerals and Waste Joint Plan which it is producing jointly with North Yorkshire County Council and the City of York Council. See North Yorkshire County Council's Minerals and Waste Joint Plan for details. In the interim, the Authority has adopted former Government planning policy on oil and gas developments as a Planning Advice Note.  

The National Park Authority has recently issued a "Positional Statement" on fracking which you can see here.

Why hasn’t the National Park Authority banned fracking?

Whilst the Authority can put planning policies in place which would enable the potential impacts of any proposed fracking developments to be rigorously assessed, banning fracking is unlikely to be legally acceptable. Before planning policies can be adopted they are subject to examination by a Government appointed Planning Inspector and are unlikely to be found ‘sound’ if not in accordance with Government policy.

What is the Government’s policy on fracking?

The Government’s current overall stance towards fracking is set out here. National planning policy is contained in the National Planning Policy Framework. Whilst this doesn’t contain specific reference to shale gas or fracking it does state that planning authorities should ‘address constraints on production and processing within areas that are licensed for oil and gas exploration or production’. Government policy in the National Planning Policy Framework relating to National Parks is equally relevant when considering any planning applications for fracking in the National Park. 

What chemicals would be used?

The proportion of chemicals making up the water / sand / chemical mix is 0.2% at the UK’s only current fracking site in Lancashire, however the potential for effects to arise from the use of chemicals would depend upon the chemicals used and the possibility of these entering water bodies. Details of the actual chemicals approved for use at the site in Lancashire are contained in the document About Shale Gas and Hydraulic Fracturing. Consent from the Environment Agency would be required prior to the use of any chemicals. 

What would happen to waste water?

Water which has been used in the fracking process is returned to the surface and may contain minerals dissolved from the shale including naturally occurring radioactive minerals. This water, known as flow-back fluid, would require treatment which could be undertaken by either having a treatment plant on site, transportation to an off-site treatment plant or by disposal to the foul sewer. Treatment at an off-site plant may involve transportation by lorry or by pipe, the effects of which would need to be assessed as part of any planning application.

What surface development is required?

Visible structures at the surface of the site in Lancashire where fracking is currently taking place include a drilling rig (around 30m high), an area of hardstanding and numerous pieces of ancillary equipment, as shown on the photographs on the operator’s website. The surface development requirements may, however, vary from site to site and the planning authority is able to impose conditions relating to landscaping and screening the site.

What permits and consents are required before fracking can take place and how is fracking monitored?

The process of fracking, including the exploration and appraisal phases, are tightly controlled and subject to a number of regulatory regimes. Four regulatory bodies are involved in issuing consents and licenses for fracking. 

The Department of Energy and Climate Change issues Petroleum Exploration and Development Licenses which give the holder exclusive rights to oil and gas exploration within a given area. This license does not give consent for drilling or any other development associated with gas exploration or production, which need to be subject to the regimes set out below. Further details on the licensing process are available on the DECC website.  

Planning permission from the Minerals Planning Authority is required at the exploration, appraisal and production phases of gas extraction. The Minerals Planning Authority for the National Park is the North York Moors National Park Authority. Applications for planning permission will be considered against the relevant planning policies and will include consideration of a range of effects such as visual impact, effects on the natural environment, effects on local amenity and vehicle movements. Applications for planning permission would need to be accompanied by an Environmental Impact Assessment. As part of the planning application process there would be an opportunity for members of the public to comment on the application.

The Environment Agency is responsible for issuing and monitoring permits related to water use, protecting water quality, the use of chemicals and the management of waste water. A permit will not be issued if it is considered that the activity would pose an unacceptable risk to the environment. The Environment Agency would also be consulted on any planning applications for fracking. More details about the Environment Agency’s role are available here

The Health and Safety Executive is responsible for regulating and monitoring the safety of the well and the site. Further details of the Health and Safety Executive’s role can be found here

Prior to drilling beginning, the Department of Energy and Climate Change must provide consent to drill. As part of this process, a Hydraulic Fracturing Programme must be prepared which will set out ways in which any seismic activity will be monitored and acted upon where necessary. This would be based on the Government’s ‘traffic light’ system

Further details of the licensing and permitting requirements are available here

If an area has a Government license for gas exploration and development does this mean that fracking can take place?

No. The Government periodically issues Petroleum Exploration and Development Licenses in geographical blocks, but planning permission and other permits must also be obtained prior to any activity taking place. The areas currently licensed are shown here. Licenses have been awarded in the southern part of the National Park and around Westerdale. A further round of licensing is anticipated to take place in 2015.

If permission is granted for exploration does this mean that production can also take place?

No. There are three distinct phases of gas development – exploration, appraisal and production. To determine whether production is likely to be commercially viable in any particular location, operators would need to obtain planning permission to carry out exploration to investigate details of the geology and the likely amounts of gas available. Planning permission and any other consents granted will relate specifically to the phase in question and do not mean that permission for production will subsequently be granted. The fracking process may be involved at any of these stages.

How is a gas injection well distinct from fracking?

Given the public interest in proposal NYM/2014/0587/EIA (Natural gas production and water re-injection at the existing borehole at Ebberston Moor South Well Site, the drilling of a second borehole for water production and re-injection etc.), a planning application for conventional gas extraction, the following information outlines the differences. 

Conventional gas extraction does not involve high pressure fracturing of the bed rock to enable shale gas to escape but is targeting gas at a shallower level. Normally, gas is under pressure and comes to the surface once it is drilled – the difference with this application is that water associated with the gas needs to be pumped out to enable the gas to then escape. That water then needs to be disposed of – which could be either through piping or tankering it away – however, in this instance the intention is to re-inject it back into a different geological layer.  Public concerns are around whether the water being pumped back under a certain level of pressure would trigger any seismic activity and whether the water could seep into other geological layers and contaminate potable water aquifers, which are essentially the source of drinking water for nearby towns. Both of these risks are extremely low – and the Coralline  Limestone water aquifer is many hundreds of metres above the layer receiving the injected water. It is also important to note that the water being re-injected has not been added to and unlike fracking fluid contains no chemicals or other pollutants – it is merely highly salty – many times more so than sea water.

The proposal is for conventional gas extraction on a small scale, which will contribute a minor but useful contribution to the nation’s energy supply needs. This helps to bridge the challenge of moving towards a lower carbon economy which, to be successful, has to be managed in a phased way as coal fired power stations are eventually replaced by a combination of lower carbon and renewable energy sources. The North York Moors has a history of small scale conventional gas extraction which, until the national debate over fracking, raised no environmental or landscape concerns from residents or the wider public.

The proposal is not a new development. It is not a completely new scheme, but a combination of two halves of schemes which have already been approved.  It represents joint working and cooperation by two gas exploration companies and therefore reduces the infrastructure requirements involved. Approval of this application means that gas from the Ebberston Moor field extracted by both companies will be piped to Knapton generating station, safeguarding local jobs and negating the need to construct a large gas processing plant at Thornton le Dale which was approved on appeal and which would have impacted adversely on local residents and the National Park.

Environmental risks are negligible. Any risks involved in re-injecting produced water from the well site back into the geology in terms of water pollution or induced seismic activity have been fully assessed as part of the Environmental Impact Assessment (EIA) with the application and this has been independently reviewed by consultants commissioned by the National Park Authority. There is nothing added to the ground water extracted, it is simply pumped back in its natural state into a different geological horizon under low pressure to allow the gas to be extracted.  The conclusions of the technical consultants are that such environmental impacts are negligible and “not significant" in EIA terms.
