The legal and regulatory framework for the EU’ shale gas exploration and production regulating public health and environmental impacts

Shale gas has now become a major competing source of energy in the international energy mix scenario. In the European Union, the “fracking” which is the technique of extraction shale gas is facing very strong opposition based on the associated potential health risks and environmental impacts which are not currently adequately regulated. The European Union Commission argues that the current regulatory system is enough for controlling the impacts of fracking on health and the environment. However, this article shows that the EU shale gas regulatory framework is not, “fit for purpose”. It will critically evaluate current European Union shale gas regulations and offer some recommendations for improvement.

Abstract Shale gas has now become a major competing source of energy in the international energy mix scenario. In the European Union, the ''fracking'' which is the technique of extraction shale gas is facing very strong opposition based on the associated potential health risks and environmental impacts which are not currently adequately regulated. The European Union Commission argues that the current regulatory system is enough for controlling the impacts of fracking on health and the environment. However, this article shows that the EU shale gas regulatory framework is not, ''fit for purpose''. It will critically evaluate current European Union shale gas regulations and offer some recommendations for improvement.

Introduction
The objective of this paper is to analyse whether the European Union (EU) shale gas regulations are fit for purpose and able to protect the environment and human health against the effects of shale gas activities. A background of the shale gas technical features and environmental potential impacts is necessary to have an understanding of what is involved in high-volume hydraulic fracturing (HVHF) processes and the potential impacts to enable an assessment of the regulations that are applied in minimising or preventing environmental damages in the EU.
In analysing the current regulatory framework for the shale gas fracking activities in the EU, it was necessary to review the EU primary legislation on shale gas industry, the legal principles influencing the legislation and the composition EU legislative bodies and their roles and the efforts the EU has been so far putting in terms of improving the regulations relating to shale gas exploration and production.
An analysis of secondary legislation relevant in permitting and operational fracking activities in the EU is also important in assessing the effectiveness and weaknesses of various provisions that regulate the potential impacts likely to cause serious environmental damage and health impacts. The environmental regulatory management systems and applications of EU member states pursuing shale gas activities will also be analysed. These reviews and analysis form the bases of the conclusions and recommendations that may contribute to the improvement of regulatory weaknesses identified.

The Background
The exploration and production (EP) involving hydraulic fracturing is currently for hydrocarbons that are unconventional including gas deposits. There is intensive public discussion going on in the European Union (EU) focusing on the potential environmental and health effects that can be brought about by carrying shale gas extraction by fracking. Shale gas extraction has become a controversial and very competitive resource in the energy mix worldwide. The United States of America (USA) is now advanced on commercial production and already reaping large economic benefits which inter alia includes the expansion of natural gas plant liquids (NGPL), manufacturing chemical, primary metals and replacing the petroleum-based naphtha7 feedstocks with increased use of NGPL feedstocks. 1 There is need for authorities and operators to abide by the regulations that are related to permitting and operational activities of shale gas exploration and production aimed at preventing or minimising environmental and human health impacts.

Shale gas potential in the European Union (EU)
In 2013, an estimation of 885 trillion cubic feet (tcf) of shale gas could be recovered in Europe, representing about 12 % of worldwide shale gas potential from all European countries by the end of 2012. 2 Fourteen European countries are believed to have shale gas resources present in their territories of which largest resources are found in France and Poland. Other states such as Norway, Ukraine, Sweden, Denmark and the United Kingdom (UK) have also large deposits. The EU is the largest world regional market for gas demand estimated at 550 billion cubic metres (BCM) in 2010, which is on the increase whilst production is decreasing in the region. 3 Unconventional gas production in the EU is expected to grow at a much slower rate from 10 BCM in 2010 and expected to grow much quicker to 80 BCM by 2035. 4 At the moment, there is no law specifically for regulating SG activities other than various EU provisions that were enacted for regulating the environmental issues and mining activities in the EU. 5 The big question is whether these unspecific but, ''catch all'', 6 directives effective enough to help gain ''social licence to operate'', and win against a growing numbers successful anti-fracking campaigns in the EU? This question will be fully answered by the end of this article.
The USA so far dominates the shale gas production resources and expected to become an overall net exporter of natural gas by 2017 and a net pipeline exporter of natural gas in 2018. 7 The gas prices are much lower in the USA as compared to the European prices.
The production of shale gas in the EU is expected to bring some of these benefits which the USA is currently enjoying. It will bring economic and energy security benefits as well as reducing aggregate gas supplies from other countries such as Russia where the supply chain can be volatile. Those who are pro-shale gas activities argue that the use of more gas helps to reduce carbon emission by replacing more carbon intense fuels and be in a position to achieve the greenhouse targets whilst some regard it as unreliable accelerator of zero-carbon society facilitating acceleration of climate change. 8 A number of potential technical and environmental concerns on the shale gas production have been so far identified, which includes water contamination, air pollution, ecological damage, noise pollution and harmful environmental pollution caused by the release of chemicals. These issues require a strong and reliable regulatory capacity covering shale gas extraction and protect health and environmental risks. 9 The risks related to shale gas exploitation demand a regulatory regime at the European level based on the, ''precautionary principle''.
However, in 2011 the Directorate General (DG) for the Energy of the European Commission (EC) reported that the environmental legislation in the EU is also applicable at every stage of shale gas activities. This prompted the initiation of a number of studies covering different aspects of shale gas activities relating to shale gas economics, methane emissions and the adequacy of regulatory framework to ensure the environment and human health are protected from the impacts caused by shale gas production. The European Parliament also debated on the shale gas's current regulatory framework's various defects. 10

Research methods
Qualitative approaches to this research shall be utilised throughout the research and collecting empirical data EU law treaties, directives, regulations, general principles and European Court of Justice (ECJ) decisions on environmental issues related to shale gas extraction.
The literature shall be briefly analysed below and reviewed throughout the article, in defining and analysing the EU legislative process, its legislative institutions and control of legislation on shale gas extraction activities in the EU and its Member States (MS). The literature will be used to understand the impacts caused by shale gas exploration and production, the effectiveness of regulations on the environmental these impacts. The response and application of the EU regulations by its MS will also be analysed.
In order to achieve this, various sources will be analysed which includes textbooks, academic research journals and articles, oil and gas industry journals, academic writings and the official EU journal EU commission. Parliament reports on shale gas policy matters and the European Environmental news information will be searched for any latest environmental issues. The United States literature which contains more detailed experiences from the shale gas activities for many years will also be looked into. Reports from the Energy Information Administration (EIA, the International Environmental Agency (IEA) and Friends of the Earth (FOE) will be used in analysing the EU shale gas environmental regulatory regime.
The ECJ plays a very important role in interpreting legislations provisions applicable to shale gas extraction and making decisions on breaches of the environmental regulations in the EU; therefore, a number of decided cases and matters referred by domestic MS for guidance will be analysed. 11 These cases are of importance in understanding the role played by the EU judicial system in regulating shale gas activities and to understand how the ECJ interprets EU environmental laws and how they are applied in deciding on shale gas cases and referrals from EU MS.

Literature review
Fracking is being encouraged by energy demand worldwide becoming a challenge to policy makers and the politicians in making environmental regulation decisions. Despite the fact that shale development in Europe is at its infancy, it is already facing a very strong opposition. The production of shale gas at this level could impact on climate change as warned by many international agencies including the IPCC 12 and the International Energy Agency. 13 The ever increasing fracking opposition makes it difficult to obtain for a social licence to operate, which was described by Moffat and Zhang as, ''A set of meaningful relationships between shareholders based on mutual trust'' 14 To have trust is to have confidence that the behaviour of an operator will match expectations of the trust holder. 15 It has been suggested that a temporal moratorium is necessary in order to get the space to thoroughly scrutinise the uncertainties of the current regulatory framework and gaps, thereby giving more protection to the environment as well as public health. 16 It is the task of the policy makers to determine if shale gas activities should be carried out in their respective jurisdictions. Many studies have shown that shale gas extraction causes a number of air and water health associated diseases and there are no conclusive reports as to the impacts caused by chemicals used in fracking due to nondisclosure agreements. 17 The need for more studies on to the potential impacts of fracking cannot be over emphasised. Another study revealed that humans, food, domesticated and wildlife die from respiratory and growth problems due to exposure to drilling and fracturing activities. 18 The biggest problem is to carry out an accurate assessment of the risks posed to on people who leave near shale gas drilling sites due to the inadequacy of current emission data collection and analysis methods. 19 Studies are carried out around the world in different geologies, geography under different regulatory regimes, engineering technologies and methodologies in each study coming up with various results making difficult to reach a consensus. However, all these studies point to the fact that there are known shale gas public health risks which policy makers should take into account when considering shale gas development policies in their respective territories. 20 There is lack of specific regulatory policy for shale gas extraction in the European Union and each member state put its own regulatory policies because the European Union cannot set up policies which affect member states' rights to choose and exploit any choice of energy within their sovereign states. 21 It is therefore the decision for each member state which has authority of issuing permits and authorising shale gas activities it its territory. There is no centralised Europe Union institution controlling these procedures across all member states.
Each state has the responsibility to take into account all public health and environmental considerations in making permitting and authorisation decisions. The lack of harmonised regulatory regime results in different EU regulatory interpretations among its member states. 22 The European Commission has a duty of strategizing enforcement of environmental regulation, making sure there is effective monitoring compliancy which is its responsibility under Art. 211 of the EC Treaty. 23 However, as shall be seen from this paper there are serious shortfalls in monitoring compliancy in the EU shale gas industry.
2 The shale gas exploration and production potential environmental impacts Shale gas has its distinct features from other fossil fuels. It has been there for many years unexploited, but due to technological advancement, it commercial production has been made possible. The peculiar methods and techniques used to extract shale gas generate its own environmental and health impacts which needs to be addressed as the project progresses.

What is shale gas?
Shale gas is natural gas with a composition of methane as the main ingredient, which is a found trapped in the source rock which it was formed originally 24 with very fine grains, of very low permeability which makes it difficult to be extracted and its extension can be as large as half of France. 25 It is said to be unconventional because the resource has to be stimulated to enable hydrocarbons to flow due to low permeability, by injecting water at a high pressure to push gas from the rock shale. It is different from the conventional gas which flows into a conventionally drilled well without stimulation giving in large quantities of economic gas. 26 Horizontal drilling and high-volume hydraulic fracturing (HVHF) are the two advanced technological processes that are used in extracting gas from its shale. Drilling using these techniques can drill a 2-km-deep well and 3 km or more horizontally. 27 These techniques have been extensively used over the last 60 years and known as fracking or hydraulic fracturing. Other types of unconventional gas are tight gas and coalbed methane, aka coal seam gas. 28 These advanced technologies have made it possible to extract shale gas in large quantities. 29 Natural gas combustion releases lower levels of carbon dioxide as well as (CO 2 ) and sulphur dioxide than other hydrocarbons such as oil and coal. When used in efficient combined cycle power plants, natural gas combustion can emit less than half as much CO 2 as coal combustion, per unit of electricity output. 30 However, SG extraction has its own technical and environmental impacts. There are currently controversies surrounding the shale gas extraction development in the EU, some advocating for a moratorium because of its negative impacts on human health and 17 Bamberger and Oswald (2012). 18 Bamberger and Oswald (2015). 19 Brown et al.

(2014). 30 See supra footnote 27. environment whilst others see it as a means to boost their nations' energy mix, cheaper and a secure energy source supply.

Issues surrounding shale gas extraction
Shale gas exploration and production has got technical and environmental issues that has to be seriously looked into for a shale gas project to take off. It is a unique and requires very technical procedure which need a lot of expertise and done in a way that is environmental friendly. Some of them cannot be avoided with the technology and scientific knowledge currently existing and the risks to the environmental and health can happen if the process of extraction is not properly managed.
2.1.2 What are the technical risks of shale gas production?
The production of SG cycle takes five stages starting from identifying the suitable site and preparation, thereby triggering potential environmental and health issues. The first stage involves levelling and clearing the required area of land for the well site. There will be transportation of heavy equipment to the site and construction of storage facilities. 31 The second stage will involve well designing, drilling, cementing and perforation of a hole on the surface and laying pipes, cementing and constructing the wellhead. 32 The third stage is the technical hydraulic fracturing, by pumping highly pressurised water mixed with sand or other propane and chemicals. Then the well reaches a completion stage where water produced and flowback has to be managed by the operator. Production will then commence and after the well has reached its end it will then need to be decommissioned. 33 However, all these stages have their peculiar environmental impacts that can start at each stage or can be accumulative from start to finish or through multiple well projects. It is the objective of the EU that individual states are obliged to make laws that regulates the potential environmental impacts on shale gas on all projects they authorise to operate in their States.
There are technical rules and regulations that operators are obliged to comply with throughout the shale gas production processes. The MS through their competent authorities are compelled to monitor the activities of the licences in their jurisdictions and to make sure they are complying with the minimum standards expected in these types of projects.

The application of the best available techniques (BAT)
''BAT'' is the most available advanced and effective way of operation which is suitable for limiting pollution in cases where it is generally difficult to reduce emission and the environmental impacts. Achieving the best results in protecting the environment needs the use of advanced technology which is economic and accessible.
The BAT needs to be applied in well construction to make sure that there are no leakages of chemicals from the well into the underground aquifer or land. However, the risks cannot be ruled out completely because there are always chances of human error or technical faults which can also result even where the BAT has been applied. MS have the responsibility of making sure that operators are complying and are up to date with the most relevant information through industrial exchange from across the EU MS and further.
Sources of such information can range from non-governmental organisations that are involved in the promotion of protecting the environmental. Operators need to put in place management systems for water, transport, gas capturing, pressure management, well management and many others which need be attended to at every stage of the operation. 34 The only problem is that SG is in its early development stage in the EU and the BAT is also just emerging and not yet fully integrated, thereby lacking a coherent approach of implementing a practice that is recognised across EM MS. 35 Figure 1 illustrates the risks caused to air, water and land by hydraulic fracturing. The diagram shows how a horizontal drilling shale gas well is set up and how it invades the natural environment from the top soil to the passing through the water table, the impermeable rock down to the shale where the fracking takes place in order to release the gas. The diagram also shows the potential locations of the sources of water pollution. The well has to be well cemented to make sure there will be no leaks of methane or hydraulic fluids into the water or soil. Figure 1 shows how the potential impacts of shale gas production on the environment. The drilling of the well passes through the fresh water aquifers where drinking water is drawn. The well integrity is important to make sure that it does not leak and hydraulic fluids during the time of production and after the decommissioning of the well. Some fugitive gases can also escape from the well to the atmosphere, polluting the air affecting human health 31 Dupont (2013). 32 ibid. 33 ibid. 34 Commission Recommendation, January 2014, on minimum principles for the exploration and production of hydrocarbons (such as shale gas) using high-volume hydraulic fracturing (2014/70/EU). 35 EC (2015).

What are the environmental impacts of shale gas production
Generally, risks to the water environment, ecology and of climate change have been identified as three main categories of key potential environmental impacts of shale gas EP calling for comprehensive risk factors (RFs) that deal with such impacts. 36 Hydraulic fracturing (HVHF) has serious impacts on land take due to its installations which take about 60 % more than a conventional well space of a well pad. Storage tanks for water, chemicals and wastewater that can contain about 30,000 m 3 and shale gas formations take up tens of thousands of square kilometres of concessions covering as large as up to 6000 km 2 . This makes the physical footprint associated with SG EP to be more than conventional resources extraction requirements. Access to land and land usage are likely to be important issues in densely populated EU countries and raises a lot of public support issues in shale gas projects.
HVHF requires a high demand of fresh water competing with other domestic and other industrial needs, depending with location of the project. Wastewater in large amount leads to groundwater contamination if not carefully disposed. The whole operation leaves footprints from increased truck traffic and noise, pollutants and demand in land use for setting up the infrastructure for the projects. Animals, plants and humans in the environment around extraction sites are put at risk of migration or possible extinction from all potential impacts such as land take, noise from traffic and site machinery, the visual impact of the environment and the increasing risk to of seismic events around the extraction area. 37 Risks associated with shale gas exploration and production using the HVHF technical methods are found at every stage of the prospection, exploration, production until closing down of the well. Ground preparation which is identified as a suitable to set up the drilling pads causes a lot of environmental disturbances. These are not going to be discussed in detail since this article's main focus is on whether these impacts are regulated effectively by the EU legislation.

The risk of water contamination
The most feared HVHF impacts are the potential risk of water contamination and depletion. This process uses a lot of water which may affect the water supply from the surrounding natural water resources or from local supply also used by the local community. Hydraulic fracturing fluid may contain potentially hazardous chemicals which may contaminate surrounding areas through spillages and leaks. Large amounts of wastewater produced by fracturing contain dissolved chemicals and need to be treated before reused or disposed. 38 Under the UK law, the environmental regulator has the power under the Water Resources Act 1991 to require shale gas developers to disclose the composition of fracturing fluids they use in their projects. 39 There are also technical standards set up in the oil and gas industry which has to be followed in shale gas activities, namely ISO 10426-1 40 which covers well cementing, ISO10405 for casings 41 and ISO 11961 42 for Drill pipes.

Induced seismicity
Instances of earthquakes have been linked to unconventional shale gas production, for example the Cuadrilla shale gas operations near Blackpool in the UK in 2011 where a small magnitude of around two on the Richter scale was reported but did not create any surface damage. 43 Hydraulic fracturing operations at Cuadrilla did not lead to a moratorium to more safety by the use of micro-seismic monitoring. 44 Operators are required to implement a ''traffic light'' to identify unusual seismic activities that may require them to stop activities pending reassessment of operation due to hydraulic fracturing. 45

Greenhouse gas emissions
SG uses higher production equipment that emits greenhouse gas emissions more than conventional gas because hydraulic fracturing need more wells to maximise production due to complex nature of its production. An operation of more wells means more diesel pumps are required thereby increasing the CO 2 emitted per unit of energy. 46 Gas is commonly released into the atmosphere or to flare, thereby converting methane to carbon dioxide, which is also a greenhouse gas. There is now an increasing use of reduced emission completions (REC) technologies to capture the emerging gas emissions. 47

Ecological impacts
The physical footprint associated with SG EP considering the number of wells that might be required, space for transport, wastewater storage facilities and containers is quite significant as compared to that of a conventional gas project. Construction of infrastructure and production activities result in the fragmentation of environmental natural habitat lost or totally destroyed especially in some of the UK onshore gas licensing that are in some special areas of conservation (SACs) or other protected category special areas, 48 and also in Poland where Chevron was licensed to explore shale gas in a UNESCO reserve, comprising terrestrial, marine and coastal ecosystem. 49

The position of shale production in the EU MS
Despite the potential economic advantages of shale gas production in the EU, its MS are widely and dived on whether they need to carry out the SG production and if there is enough regulation. 50 The EU needs shale gas to augment its energy demands, but, however, different opinions on developing it emerge within EU member states which is likely to slow down the speed at which shale gas can be developed in the EU.
A significant figure of about 60 % of the EU public does not want SG activities to take place in their territories as statistics worked on the proportionality of individual member state (MS). 51 Other MS such as Poland consider SG production for bringing economic prosperity, creating more jobs and ensure energy security. 52 Others are more worried about the harmful effects of HVHF in their respective countries calling for more scientific tests to be carried out on the potential environmental impacts of developing shale gas in their territories. 53 Most prospective areas for shale gas development in the EU are found in densely populated areas which have very strong antifracking campaign groups in most EU MS, 54 which makes access to land and land usage to be important issues especially in densely populated EU countries. Figure 2 shows EU countries with SG deposits and shows which countries have issued a moratorium in HVHF, allowed it and those which have already issued permits.
States such as France and Scotland have imposed a moratorium on exploitation of shale gas. It is also problematic for the development of shale gas even in some countries willing to pursue shale gas activities projects due to immense pressure from anti-fracking groups. For example, in England, recently Lancashire county council rejected an energy firm, Cuadrilla a permit to start fracking on the Flybe Coast, an area located between Preston and Blackpool on grounds of, ''unacceptable noise impact''. 55 At EU level harmonised and consistent approaches are favoured by the majority of EU Citizens. Environmental NGOs prefer strengthening of environmental safeguards 40 Petroleum and Natural Gas Industries (2009). 41 Petroleum and Natural Gas Industries (2006). 42 Petroleum and Natural Gas Industries (2011). 43 See supra footnote 8. 44 Green et al. (2012). 45 Fleming (2012). 51 Sreeramula (2013). 52 Bugarski and Maulet (2013). 53 Pearson et al. (2012). 54 See supra footnote 3. 55 Petroleum Review (2015).
The legal and regulatory framework for the EU' shale gas exploration and production… 7 through regulatory framework. Soft measures and consideration of amending the existing law are preferred by the oil and gas industry, whilst specific comprehensive EU legislation was preferable to operators and service companies. 56 However EU, member states are also widely dived on how the SG production projects should be regulated. 57 These differences between organisations, the public and governments all add up to the complications involved in finding a legal lasting solution in regulating SG activities in the EU. The nature of some of the impacts will be justify action to be taken at EU level where environmental impacts and the risks migrate from one MS to another, particularly surface and groundwaters as well as air quality and greenhouse emissions. 58 Coordinated efforts by states which share boundaries where such projects are to take place in terms of programme management planning are important. This is discussed in more detail in Chapter 4 under strategic impact assessment (SIA).
The precise volumes of unconventional hydrocarbons available in the EU are uncertain as there are different estimates of technically recoverable SG in the EU from different sources. In 2013 the Federal Institute for German Geosciences and Natural Resources(BGR) estimated reserves to 16 trillion cubic metres (tcm), 59 and in 2014 reassessment went down to 16 tcm and in 2014 EU Commission estimated it at 16 tcm. 60 Some of these estimates also combine shale gas, CMB and tight gas together as unconventional natural gas. The sustainability of the shale gas industry cannot be guaranteed and hence the need for taking precautionary measures in safeguarding the environment and the health of human beings form the effects of shale gas activities on any related projects that are taken. 61 There is an estimation of 73 % technically recoverable gas in the EU split between a number of counters 62 which some of them have totally banned the shale gas extraction activities and the EU size of economically recoverable gas is also uncertain. Resources that can be produced with the available technology and able to make profit are what are called technically recoverable resource. 63 Total bans were imposed in France, Bulgaria and Scotland whilst temporal moratorium on fracturing practices was imposed in Denmark, and North Rhine, in Germany on public concerns. Exploration projects which require the use of HVHF to carry out the tests may become impossible in some countries which makes it difficult to get the correct data.
Shale gas is infinite just like the rest of all other carbohydrates; therefore, it is essential to always be conscious that is will deplete in the end leaving an indefinite environmental and health impact which may not be proportional to the benefits that may be realised today.

The EU SG environmental legislation
The EU shale gas legislation is a made up of a Primary, secondary legislation, some EU and international legal principles. The EU has its legislative institutions which make and enforce the law on its entire MS. It is therefore important to analyse these institutions, their roles and how they make and implement law within its MS. Various legal principles applied in making the EU law and used by the courts to interpret the laws relating to the environmental impacts of shale gas activities shall also be analysed.

The European Union, institutions and legislation
The EU promotes and defends its values, objectives and its citizen's interests and its entire MS through its institutional framework. There are currently 28 states who are EU MS with Croatia being the most recent member to join in 2013. 64 The membership is still growing and currently Turkey, Albania and three others are on the waiting list as potential candidates. The expansion of the EU membership, covering a very wide area with different, geography, demographics, geophysics, needs a very effective legal framework to address the impacts of shale gas activities. The EU is regarded as a region with environmental standards that are highest in the world and its current policy, the 7th Environmental Action Programme (EAP) 2010 outlined the EU institutions and MS' dual responsibilities and sets out long term strategy catering for environmental challenges. 65 The EU's the legislative powers generally lie with, the European Parliament (EP) where MPs are directly elected by EU MS citizens, the Council of the European Union (CEU) represents individual MS governments and tasked with setting EU overall political agendas but without powers to pass laws and is headed by a President on rotational bases. Then the EC is the EU's executive body which represents the whole Union's interests responsible for proposing and implementing EU laws. 66 Then finally the ECJ is the EU's judicial body responsible for the application of EU law and making sure it is interpreted in compatible with the EU Law. EU regulations take precedence over national laws of its MS and the EC is responsible for monitoring MS to make sure they implement and effectively enforce the EU legislation as directed and achieving the objectives of the directives. MS national courts judges can refer matters to the ECJ for preliminary ruling of EU law. Where a MS fails or delays to implement or acted in contrary to the EU legislation, the EC can warn the MS or issue proceeding in the ECJ for violating the EU law. 67 Legal action will only be taken as a last resort otherwise the EC put greater emphasis on helping MS to effectively implement the law, capacity building and financial support. 68 MS have the rights to make their own environmental legislation in their MSs as long it is compatible with the EU law.
The Treaty on the Functioning of the European Union (TFEU) limits powers that can be exercised by the EU institutions. The EU institutions' power to issue environmental law is derived from Article 191 and 192 of the TFEU which can make regulations which have a direct effect 69 meaning that individuals can invoke EU provisions in a national court and get remedies without going to the ECJ directly.
The Lisbon Treaty empowers both EU institutes and individual MS powers to legislate on energy issues; however, MS can only exercise such powers provided the EU has not done so. 70 MS have a duty to make sure shale gas activities are regulated to the highest standards based on scientific and qualitative data, and making sure public participation is involved in the process is effectively monitored. 71 There are a number of Treaties which forms part of the EU legislation relevant to the regulation of shale gas activities in the EU. Article 37 of the Charter of Fundamental Rights of the European require the environmental quality improvement and to be imbedded into the EU policies and protected at a higher level and also according to charter of the Treaty European on Union (TEU) and the TFEU. 72

Legal principles shaping shale gas legislation
The principles are some of the most important sources of the International and EU law, which are rules of human behaviour which have been in practice since time immemorial before the written law. These doctrines appear in many legal documents and are used by the courts in interpreting the law. Article 191 (2) TFEU outlines the settled rules of law which are clear and need not to be proved in court which the EU Environmental Policy is based on. 73

The precautionary principle
EU institutions are urged to swiftly act without delay in situations where harmful consequences to the environment are strongly suspected of as provided in Article 191 64 European Union, Countries (2016). 65  . 66 Europa (2016 (2)s 2 TFEU and Directive 98/81/EC. 74 Prevention is better than cure; therefore, precautionary measures are to be applied in making decisions concerning shale gas activities. In doing so, the proportionality principle by weighing effects of the impacts on the environment against other needs such as energy, economic and security should also be observed. However, all MS have the freedom to decide taking measures at the highest level including not to pursue authorise or permit shale gas activities if they believe that would be the most appropriate safest thing to do.

Principle of permanent sovereignty over natural resources (PSNR)
The principle was established by the United Nations General Assembly (UNGA) in on its resolution 1314(XIII) 12 December 1958. 75 The concept of PSNR is part of international law which gives sovereign states the primary responsibility over the rights of their natural resources and legal power to enter into agreements with other nations and international oil and gas developers to pursue extraction activities. 76 Under this doctrine, governments enjoy exclusive rights and freedom of national wealth and its distribution in their national interests. Individual states have the sovereign rights over natural resources lying between states and outside the jurisdiction of national states which belongs to the international community. 77 This principle was adopted in the EU law under Article 1 of the Directive 94/22/EC 78 directive which empowers MS as custodians and owners of natural resources in their geographical jurisdictions through their responsible authorities to permit any suitable and competent entity exclusive rights to explore and produce hydrocarbons. 79 In the EU exploitation rights of the subsoil belong to the state and the surface remains the property of the landowner. This is different from the USA where mineral rights are owned by private individual who simply negotiate with a company to develop shale gas exploitation on his land on a fee or develop himself if he is capable to do so.
In many countries worldwide, minerals are owned by the state including in the EU member states. The owner of the land maybe is compensated for giving away land for mineral development. This may be the reason why there is so much resistance in Shale gas activities in some EU MS State such as the UK. It could be on the basis of environmental or the ''Not-in-my-backyard factor'' (NIMBY) or and lack of incentive to persuade land owners or the local communities to consent to SG developments. The minerals belong to the state and central government reaps the benefits and not local government where the public might feel have a more direct benefit from projects that take place in their local communities. 80 The PSNR doctrine was adopted into the EU law, under Article 194 (2), giving the EU member states the right to their energy mix of which they may choose to include or to exclude shale gas to be part of their energy national resource. 81 Therefore, there is currently no jurisdiction for the EU over its member states on decisions on hydrocarbons or programmes for resource development.
Natural resources are described as naturally available raw materials that are not man made, that are accessible to sustain human needs in line with international law, national law, customs supported by international organisations that oversee resource trading. 82 EU MS have the choice of authorising developers who meet their criteria for exploration and production shale gas in their territories and are responsible for the monitoring and enforcing EU law and their national shale gas exploration and production regulations.
The present regulation on shale gas development was not specifically crafted for shale gas activities but for conventional exploration and production activities; however, the EU commission in 2011 declared that it was also applicable to the unconventional exploration and production. 83

The principle of subsidiarity
Under the principle of subsidiarity, the EU can only act where member states cannot meet the objectives of any proposed action sufficiently at central, local, regional level or where the Union is in a better position to provide the best remedy due to the magnitude and effects of a problem. 84 The EU is required to apply the principle of proportionality in achieving the objectives of the Treaties and not to act beyond what is necessary. 85 The principle of subsidiarity tries to limit the EU's legislative powers and devolve regulatory powers to individual member states. This is in appreciation of the fact 74 Hámor et al. (2010). 75 The United Nations, Human Rights, General Assembly resolution 1803 (XVII) of 14 December 1962. 76 Shaw (2008. 77 Nagan and Hammer (2004). 78 Directive 94/22/EC of the European Parliament and of the Council of 30 May 1994 on the conditions for granting and using authorizations for the prospection, exploration and production of hydrocarbons (1994) OJ L164/3. 79 Ibid. 80 Dobra and Newman (2014 that traditions within Europe are diverse where certain issues are best dealt with at national level rather than at EU level. 86 The EU law under the principle of subsidiarity allows MS to make domestic laws that are suitable for governing shale gas extraction activities in their territories in addition to the available relevant EU regulations.
The EU MS have the duty to make laws and policies to administer and control the environmental effects of any shale gas extraction activities they authorise in their jurisdictions because the closeness to their environment increases their strength of responsibility. 87

The Golden Rules
The International Energy Agency (IEA) developed a set of, ''Golden Rules'' aimed at opening ways of a massive shale gas unconventional development by suggesting policies that can be used by policy makers, regulators and operators in addressing environmental social impacts of shale gas activities. The Golden Rules encourage local community engagements, monitoring environmental impacts and transparency as a way of gaining social licence to operate. 88 The Golden Rules recommend effective regulatory regimes for safe development of unconventional gas in terms from planning, development, risk assessments and monitoring-related potential impacts and management of wastewater management and reduction in greenhouse emissions. 89 EU MS can apply these Golden Rules in developing their own environmental shale gas policies to regulate their national shale gas activities.

Shale gas legislative developments in the EU
The EU's legislation for shale gas exploration and production is made up of various EU pieces of legislation comprising the acquis commununutaire, treaties, regulations and directives and decisions as well as recommendations. The EU has over the years been working out to improve the effectiveness of shale gas legislation in making sure they are good enough to deal with the potential environmental impacts. The European Council in 2011, called for an assessment of sustainable extraction and enhancement of energy security by using the unconventional carbohydrates in the EU. A number of reports followed which ended up with a recommendation in 2014.

Philippe and partners commission report
The Director-General for the Energy of the European Commission awarded a tender to Philippe and Partners based in Brussels to make a report on the EU environmental legislation's appropriateness to shale gas projects. In November 2011 a report was published on the transposition of EU Directives into national law enabling MS to regulate shale gas activities in their jurisdictions. 90 The report also stated that there was no noticeable gap at the European level or national level in regulating shale gas in Germany, France Poland and Sweden.
The report was, however, criticised for being biased because the law firm Philippe and Partners had a lot of shale gas company clients involved in shale gas activities in the EU. 91 This was a clear conflict of interest which the law firm should have recused itself from bidding or being awarded the tender to compile such a report.
When new regulatory provisions are introduced, they have financial implications on the developers and governments implementing them. The Environmental Impact Assessment (EIA)'s difficulties in implementing have been fruitful to environmental Lawyers in the EU by representing parties in national courts and commission proceedings. 92 EIA is costly because it needs teams of expert consultants and teams of lawyers to look into any related challenges. These cases are voluminous and can take years to resolve meanwhile solicitors will be making money. 93 Therefore, a law firm with clients already in this field cannot be seen to be making a fair and equitable report on issues involving their clients' interests, its unethical.

European Commission EIA guidance 2011
The EC published guidance on how to apply the EIA Directive to advanced techniques as the hydraulic fracturing and horizontal drilling in 2011. 94 This directive ensures the permitting process include environmental issues with potential significant environmental effects, how public should be involved in decision making in granting permissions. This guidance also explained the thresholds which the EIA would become mandatory. The conclusion was that there is already a comprehensive environmental legal framework that is applicable to both conventional and 86 Critchley (1995 Aitken et al. (2012). 92 Simons (2014). 93 ibid. 94 Guidance note on the application of Directive 85/337/EEC to projects related to the exploration and exploitation of unconventional hydrocarbon.
The legal and regulatory framework for the EU' shale gas exploration and production… 11 unconventional carbohydrates activities from permitting to decommissioning. 95

Janez Potocnik: transmission note
As public concern continued to haunt shale gas activities in the EU, the European Parliament (EP) requested for guidance from the European Commission's Environment Commissioner on carbohydrates unconventional exploitation legal framework. A note was issued on the 20 January 2012 outlining the drilling and hydraulic fracturing of shale gas wells and its production and the potential environmental impacts at different project stages and explaining the existing EU law relevant to such activities. 96 EIA was confirmed to apply at authorising stage of the project and the need for public participation permitting in decision making. It basically explained issues covered by the already existing directives and did not point out any new risks not covered already.

European Commission public consultation
A public consultation was initiated by the EC for the period of December 2012 to March 2013 asking whether the public approve unconventional hydrocarbons development in Europe and their opinion on the existing legislation's adequacy by considering given five alternatives. The indication from the responses from the public showed that there was need for additional action to be taken on the regulatory framework at EU level and need for a comprehensive new regulation framework. 97

European Commission studies
A number of studies were then commissioned by the EC to assess the shale gas impacts on market and climate change, human and environmental risks, application of regulatory provisions and chemical registration usable in hydraulic fracturing. This study was a bit more critical and came out with a number of conclusions. The study concluded that MS generally relied on the Mining and environmental legislation adopted from the EU available legislation being applied without any distinction between conventional and unconventional oil and gas. Uncertainties in certain EU legislation were found, especially on how flowback fluids should be treated. Lack of knowledge within MS on the areas covered by the EIA to shale activities and impacts that are accumulative on the project was also identified. The report also found that there was no legal requirement for casing and cementing on unconventional wells whilst other countries such as the UK apply their own design, construction and integrity rules of 1996 which are also applicable to conventional wells. 98

The 22 January 2014 commission recommendation (CR)
The EU Environmental legislation was not done with shale gas activities in mind, and therefore, there is no specific shale gas legislation other than the general environmental legislations which covers other industrial and environmental issues in the EU. The EC after having promised to table new laws to regulate shale gas extraction, decided to let the MS governments to take charge of this controversial activity. The EU Commission decided to propose a set of recommendations outlining the minimum standards to its MS to maintain environmental standards. 99 This CR was adopted by the EC on activities specifically concerning HVHF on shale gas and oil exploration and production activities in the EU 100 and defined HVHF activities as those with a water injection in excess of 1000 m 3 of water per well or 10,000 m 3 for the entire fracturing process. This can technically exclude activities which do not HVHF up to these thresholds and that could be a loophole to escape the recommendations and risk to environment.
The key recommendations included the strategic planning and impact assessment, permitting, exploration and production, site selection and baseline studies throughout the whole production process up to post operation closure and surveying. 101 The framework of the recommendations encourages all member states who wish to engage in shale gas extraction to apply a set of protective measures that are common and of minimum standards in addition to the existing EU Law. 102 The interested countries are encouraged to carry out an EIA before issuing high-volume fracturing licence 103 and have to be done for each individual shale gas project. 104 According to EU law, Regulations, Directives and Decisions are legally binding at different degrees. Recommendations and Opinions are not legally binding but constitute soft law which may not have direct effect. 95 Vopel (2012 However, Recommendations have been urged to be taken into account by national courts by the ECJ as a tool for interpreting national laws. These can also be used by administrative staff and quasi-judicial authorities who deal with shale gas projects processes. 105 The CR is not being followed by MS as recommended due to its weaknesses, attitudes and competences of certain MS in implementing EU law. More analysis and a number of examples are given in Chapter 4.

EU environmental law enforcement
There are a number of environmental breaches that are committed by MS such as failing to communicate implementing measures for directives to the Commission, failure to comply with ECJ judgements within a reasonable time and breaching EU law with far reaching consequences. These are to be resolved and enforced through the available judicial processes at EU level in the ECJ and within the EU MS's national courts, the National Ombudsmen and the Alternative Dispute Resolution (ADR) processes which some MS have established a self-regulatory mediation culture whilst in some it still developing.

The role of the European Court of Justice
It is the responsibility of the EC as, ''the guardian of treaties'', to enforce the community environmental law and make sure MS comply with the apply TEU and TFEU and all measures covering environmental impact issues. 106 The Commission has got the power to bring MS that fail to comply with the EU treaties before the ECJ. 107 The court may find the MS liable for damages or loss caused by its failure to enforce the environmental law under the principle of state liability. 108 If there are any complainants claiming damages, they have to satisfy that the rule of the EU that was infringed was intended to confer them rights, and there must be a serious breach of the rule and an established connection between the breach and the damages suffered by the individual. 109 MS Judges can refer a question to the ECJ on how to interpret EU Directives and not hypothetical problems or those which have already been decided or resolved. Any decision made by the ECJ is binding and is superior than EU MS states domestic courts. The ECJ can only deal with complains referred by the MS national courts which have jurisdiction to deal with such matters and can impose fines which are quite substantial and calculated at in relation to GDP on MS failing to comply with its decisions within a reasonable period. 110

National courts
MS national courts have jurisdiction to deal with environmental breaches that occur in their territorial jurisdictions under the civil process or criminal process under Directive 2008/EC. 111 It is a strict liability offence to breach a national environmental statute provision which can be an EU directive transposed into an EU MS national law or an EU regulation which has a direct effect in all MS.

Quasi-judicial process: the Ombudsman
Ombudsmen were suggested to be involved in handling environmental complains within their member states but some States such as Italy and Germany have no Ombudsmen. In most countries Ombudsmen deal with reviewing public bodies decisions and handle disputes of individuals with administrative bodies. It has been recommended that each MS should have an Ombudsman as an independent establishment to handle public environmental complains. 112 There are, however, other weaknesses in utilising the Ombudsman's office to deal with environmental matters besides that they are not established in every EU MS. Ombudsmen have got a discretion to lounge an investigation of any complaint made to their offices and they may decide not to pursue some shale gas environmental disputes. Operational financial difficulties and lack independence for example in France where only complaints referred by a Member of Parliament. Lack of environmental knowledge has been identified as a weakness in utilising the Ombudsman in dealing with environmental disputes. 113 It is high time special environmental courts are also set up in the EU like the, Green Benches in Brazil. 114 The EU Forum of Judges for the Environment for exchanging views on the implementation and interpretation of EU law and training national sitting judges on Environmental issues which is supported by the Environmental Directorate General since it was established in 2004 is also 105 see supra footnote 50.  Environment (2014). 113 European Parliament, Compliancy Promotion (2012). 114 Benidickson et al. (2011).
The legal and regulatory framework for the EU' shale gas exploration and production… 13 doing a good service for the towards effective judicial environmental protection. 115

Alternative dispute resolution (ADR)
ADR would be best suited for resolving environmental conflicts which are complex and challenging. Environmental problems that can be resolved included among other things, culture, property rights legal and regulatory matters which can be brought by private individuals, members of the public or can be multijurisdictional and by those with special interests. ADR has its advantages over legal and regulatory processes besides saving money and time, stakeholder's ownership and confidentiality it is has a holistic approach and takes a wider picture a wider picture on the environment and not on a particular development. ADR has been used in the United States of America in a number of environmental disputes relating to shale gas activities. 116

The EU shale gas regulatory framework
The EU shale gas exploration and production activities are regulated in the existing EU legislation dealing with authorisation of carbohydrates prospection, exploration, production and other connected activities even though this legislation is not specific for shale gas activities but have fracking features. 117 The CR point (7) states that hydrocarbon exploration and productions involving HVHF are covered under the general EU environmental law and other various directives which the EU MS can use in regulating SG activities. The important permitting and operational regulations recommended by the commission and other EU relevant to shale gas activities will be critically analysed.

Permitting and licensing regulations
Any exploration and production of hydrocarbons including shale gas has to be authorised by each MS as the controller of its natural resources through its competent authority. Hydrocarbon exploration and production plans have to go through the licensing and permitting procedures first before any development takes place. It is the responsibility of a competent authority to deal with authorising activities on behalf of the individual States. 118 Generally, the process of exploration is to identify the resources and its quantities and to assess its viability to exploit, technically and economically before the production of the hydrocarbon extraction process can commence. 119 MS are prohibited to be discriminatory in the process of issuing of authorisations and permits for exploring and hydrocarbons, including shale gas. 120 An entity established in another EU member state is free to establish business and provide services in another MS without any restrictions. 121 Entities from third nations may also be granted permission at the discretion of the MS where development is to take place. The authorities grant exclusive rights of exploration and exploitation of hydrocarbons to the developer for an agreed period in a specified geographical area by issuing a licence, and then a permit is required for doing the actual operations, which both can be referred to as ''concessions''. 122 The EU general environmental directives are applicable to exploration and production of carbohydrates involving HVHF. These directives among other things outline the legal framework for competent authorities to carry out impact assessments and issuing of permits.

Strategic environmental assessment (SEA)
The SEA) Directive (2001/42/EC) focuses on issues involving programmes plans and polices determining the overall bigger picture to achieve certain goals. 123 SEA can protect the environment which we all depend on especially the poor people, by promoting sustainable development and poverty reduction. It is an essential tool in making strategic decisions on policy, planning and programmes. A number of developmental outcomes can be achieved by integrating the environment and development by making decisions based on environmental evidence. Opportunities are then easily identified, preventing expensive mistakes and promoting decision making through public engagements which improves governance and facilitating transboundary cooperation. 124 It is a good way of managing successful projects because every stage is reviewed periodically and actions 115 European Commission, Environment (2016). 116 Disputes in the energy sector financier Worldwide October 2014 (2014). 117  have a timeline and all the components are part of the strategic plan. 125 A SEA is the first step to be taken by an authority in considering permits for prospecting, exploration and the production of hydrocarbons. Where a development is at a large scale an assessment of impacts should be carried out from constructing the well site and carrying out seismic tests and preliminary drilling. An SEA needs to be carried out before the licences are issued on projects requiring HVHF. This assessment reports on potential impacts on the environment, biodiversity, population, water, air, flora, fauna, climatic conditions, cultural and archaeological heritage, landscape and human health.
Projects that are commenced without an SEA have the potential of being overwhelmed with the impacts of risks at a later stage which could be identified if a AEA is take at earlier stages. Figure 3 illustrates the decision making hierarchy in programmes, plans, projects and policies. Figure 3 shows how the SEA integrates environmental considerations in plans and programmes at policy level taking in the context of the political, governance and institutional process of making decisions. 126 This is where all risks are assessed, eliminated and strategizing risk mitigation on individual projects before they commence. All this has to be done in line with the outcomes of the initial assessment of the whole programme. This will strategically eliminate conflicts as the project progresses by giving this overall territorial planning approach (Fig. 3).
The IEA also recommended countries to take strategic planning in regulating large industrial operations of unconventional production which is more evasive than the conventional activities. In its ''Seven Golden Rules'' the IEA recommended that timely interventions and early strategic assessments should be carried out by public authorities before any project commences. 127 The EU Commission Recommendation clearly stated that a strategic environmental assessment should be prepared in terms of the Directive 2001/42/EC before HVHF exploration or production licences are issued. 128 The Espoo Convention in 2003 also promoted the use of SEA in national legislative and policy decisions in a trans-boundary context. 129 SEA Directive requires all government programmes including those financed by the European community whose plans are capable of having significant environmental impact to be strategically assessed by all MS. 130 The aim of SEA is to assist the authorities with necessary information in making decisions involving HVHF processes. Shale gas as a natural gas requires SEA as part of country planning. 131 It is then surprising that some MS do not follow this recommendation which is a good project management strategy followed by many organisations which manages projects as a matter of good practice. The idea of jumping straight into running projects is a risk way of conducting any type business projects because it lacks risk evaluation, unsustainable and results in poor quality of outcomes. 132

Are the member states complying with SEA?
The SEA directive has been breached by a number of the MS despite its importance and recommendations. Spain rejected implementing SEA, arguing that exploration licence applications cannot be considered plans or programmes because the area to be assessed will not be awarded to anyone yet or a pending request for an award, except when the area was offered by the Autonomous Regional Government or the Council of Minister which require a SEA. 133 Poland also argues that issuing of shale gas licences is an administrative decision and not plans or programmes which need SEA and went ahead and issued hundreds of exploration permits. It issued the Zwierzzyniec permit to Chevron covering a very wide area of Natura 2000 sites as well as Roztocze National Park a UNESCO, ''biosphere'', reserve, meaning it comprises terrestrial, marine and coastal ecosystem 134 The United Kingdom DECC which is responsible for issuing licences to explore hydrocarbons under its Petroleum Act 1988, 135 on its 13 shale gas licensing rounds it issued Cuadrilla's licences in Lancashire (PEDL) 165 and Balcombe site in West Sussex without conducting SEA, thereby breaching Directive 2001/42 and the Commission Recommendation (3.1) 136 All these breaches can result in serious damage to the environment and human health. It is clear that as SEA covers a bigger programme area where licences will be issued for individual projects and then EIA should be done on every project authorised to take place.

Environmental impacts assessments
The EIA 2011/92/EU as amended by Directive 2014/52/EU ensures that significant environmental impacts are identified and accordingly addressed before decisions to allow a project that may have environmental impacts to proceed. 137 This directive has a wide scope and intended for a broad purpose. 138 It, however, fails to take into account the peculiar features of a shale gas well. A shale gas well rapidly declines its production, lower in gas production per well as compared to a conventional well production and cumulative impacts from high number of wells required. EIA is mandatory for commercial natural gas extraction projects with a production exceeding 500,000 m 3 per day. 139 This is unlikely to be achieved considering the EU's shale gas production rates. A shale gas well produces roughly 250,000 m 3 in its initial stages reducing to less than 100,000 m 3 per day which makes it below the threshold for the EIA to be compulsory. 140 The EC and the European Council in 2014 EIA review rejected clauses voted for by the EP on the 9 October which was calling for shale gas activities to be included under mandatory EIA Annex 1 of the EIA Directive. This could have made shale gas hydraulic fracturing classified as an activity having significant effect on the environment, thereby requiring compulsory EIA under Annex 1. 141 The provisions do not specifically provide for multi-wells cumulative production under Annex 1 of the directive 142 Shale gas projects can have many wells drilled on a project, and as in-re Brussels Hoofdstedelijk Gewest, 143 the cumulative effect of several projects cannot escape the impact assessment obligation since combined impacts from a number of wells can cause significant effects on the environment under Article 2 (1) of the EIA Directive. Therefore, even if the directives do not expressly say that accumulative impacts from several wells on a project should be assessed together case law has clarified that shortfall.
According to a study carried out by Milieu limited on behalf of the EC Directorate General Environment, certain EU MS countries made EIA a mandatory requirement for unconventional gas exploration and production, for example, Bulgaria made it mandatory since 2012, it is also mandatory in Denmark and in Lithuania for both conventional and unconventional exploitation of hydrocarbons. Other MS simply adopted the EIA Directive without indicating whether that applies to unconventional or it is part of the process. 144

EIA weaknesses
There are inconsistences in the application of the directive between MS; however, various legal assessments done by the DGs of the EC and the EP agree that EIA should be part of the, ''best practice'' in unconventional fossil fuel projects. 145 As public concern continued to haunt shale gas activities in the EU, the European Parliament (EP) requested for guidance from the European Commission's Environment Commissioner on legal framework unconventional carbohydrates exploitation. A note was issued on the 20 January 2012 outlining the drilling and hydraulic fracturing of shale gas wells, its production, the potential environmental impacts at different project stages and explaining the existing EU law relevant to such activities. 146 EIA was confirmed to apply at authorisation stage of the project and that public participation was needed in the process of making permitting decision.
Impacts not known prior to the EIA exercise cannot be assessed and can lead to an unanticipated pollution to unknown aquifers in the surrounding geographic area and lack of obligation for geological assessment.
A decision to grant exploration and production permit by a responsible authority may not be through public participation or based on impact assessment therefore possible impacts may not be known and assessed especially where the process is by consent. 147

MS monitoring capacity and competency
Competent authorities require adequate human manpower, technical and financial resources in order to do their duties diligently as recommended in chapter 13 of the CR. 148 However, according to the technical risk management report by AMEC on behalf of the ECDG environment, this policy option attracts higher compliancy costs per-year per pad as compared to tight gas, oil and CMB compliancy costs. 149 The lack of capacity to monitor and enforce the regulations independently by MS competent authorities shows that some MS just transpose the legislative text but do not enforce as required by the law. There have been issues concerning conflicts of interests and corruption activities related to shale gas authorisations in some MS. The following examples illustrate MS which failed to prevent conflicts of interests in terms of Section (2) of Chapter 13 of the recommendations.
The first example in the UK, Sir Phillip Dilley was appointed as the chairman of a UK Environment Agency with the responsibility for granting permits for fracking across the UK. Mr Dilley had been the chairman of Arup an engineering company which was responsible for writing reports for Cuadrilla, a shale gas developing company in the UK. 150 An independent investigation in December 2014 found out that £2.3bn was invested in fracking investment companies by the UK Environmental Authority. 151 The likelihood is that the majority of the decisions are favourable to the state to the detriment of other stakeholders and indirectly impacting public health and the environment.
Another example is that the Polish Geological Institute, the Environmental Ministry and Gas Company officials were indicted on licensing corruption charges. 152 The Polish Supreme Audit Commission 2014 reported some irregularities on public administration and private entities interested in shale gas exploration in Poland. The Commission found that there was no appointment of a government official who was overseeing the overall management controls of shale gas activities. 153 There were only three officials with the responsibility of issuing licences between 2007 and 2012, and decisions were made by the Environmental Minister himself. The decisions were taking an average of 132 days instead of 30 days as required by law and officials were accepting bribes for helping developers to win concessions. 154 Romania lacks technical expertise and its national regulations allow hiring of specialist's agencies whenever needed. The national authorities failed to organise specialist agencies despite being requested by its local environmental authority for carrying out environmental assessments on four wells in Barlad Region. 155 The chances of achieving the objectives targeted by the Recommendation are compromised in such situations where there are elements of corruption and conflicts of interests. Concessions will be awarded unfairly to entities that pay higher bribes that may not have the necessary expertise and financial backing strong enough to carry out such big delicate projects successfully, putting risks to the environment and human beings.

Public participation
The CR 2014 recommends public authorities in the EU to involve public participation and access to the justice system on environmental matters. 156  strengthening public participation, transparency reflecting the dynamics of the environment, changes in the society and regulatory challenges. 158 Shale gas projects needs a social licence to operate, which is an acceptable level of approval given to developers by the stakeholders especially the local communities that are impacted by such developments. These are a set of mutual trust based relationship between operational stakeholders. 159 Multinational companies pursuing shale gas activities should aim to meet the diverse expectations the local communities as well as the NGOs to ensure they do not put their reputation in jeopardy subjecting themselves to all forms of destabilisation resulting in discontinuation of projects whilst incurring huge financial costs. 160 There is need for a Free, Prior and Informed Consent (FPIC) by developers which is a human right-based approach ensuring the right of indigenous peoples to selfdetermination. 161 There should be no pressure or cohesion from the organisation or the state. Consent should be sort before any activities are carried out and the project should be explained in an unambiguous language clearly understood by the local community. 162 International financial institutions will not provide funding for developers who do not want to commit to the global finance industry's corporate social responsibility and sustainability framework aka the Equator Principle aimed at assessing and managing environmental and social risks on all international projects. 163 Members of the public and NGOs should be afforded the opportunity to make comments which competent authority would take into account in making project development decisions. The need to inform the public about all final decisions, how the environmental impacts will be put under control and how compensation for damages will be worked out. The public is entitled to retain the right to object to the decision in court if they disagree. 164 The public is not being given enough opportunity to participate in permitting decisions in some MS, and for example in the UK as from August 2015 Ministers were authorised to upset the local authority's decision where they felt a shale drilling application is taking too long. 165 In this case the public will not get any opportunity to make meaningful contributions even if they are given the chance to do so. A good example is as when the public were given three weeks to go over 9000 pages of environmental statements from a developer, Cuadrilla where an application was made for an extension of time. 166 It is absurd that ordinary members of the public or even professionals would be expected to digest a 9000-page document involving a specialised project, with a lot of technicalities within three weeks and which may also need consultation before commenting.

Wastewater management
Dealing with millions of gallons of HVHF wastewater is a big issue. In the USA it is injected in deep well injection sites, which in Texas 8000 disposal wells and 25,000 for waste fluids. 167 Over the period between 2008 and 2009 public sewage plants were used to dispose wastewater from HVHF projects in Pennsylvania where 271 cases have been confirmed cases of waterways degradation from shale gas hazardous waste. 168 The EU MS should learn from the USA experience and not repeat the same mistakes which some of them have solutions available.
In the UK wastewater was discharged into Manchester Ship Canal after going through a local facility basic water treatment 169 and German's Environmental Agency recommended deep well injection or recycling but cautioning that there was not yet the best sustainable waste management practice. 170 This indicates how desperate the industry is in managing wastewater which so far in the EU can only be protected by Mining Waste Directive (2006/21/EC) not specifically drafted to deal with HVHF risks.
Operators are to comply with certain specific obligations in accordance with the directive. Any substances which the operator is by law required to dispose or intends to do so is classified as waste 171 including drilling muds 172 and water from HVHF. 173 A waste facility for HVHF processes will need a permit from a competent authority to be allowed to operate. 174 The permit put measures in place at waste facilities to prevent accidents and environmental impacts and for waste management related facilities on the site. Wastewater discharged to the surface is also regulated by a permit under the Mining Waste Directive, Industrial Emissions Directive and Water Framework Directive which were all not meant to deal with specific risks emanating from shale gas activities. It is the duty of the operator to put in place regular monitoring and inspection arrangements of the waste facility by competent staff and taking measures that threaten water or soil instability and contamination. 175 EU law requires MS to decide on the frequency of inspections on operators' waste management facilities and records on projects by is carried out by their competent authorities. Operators have to keep waste management records updated and ready for inspection by competent authorities and the records should be appropriately transferred in the event of changing operators. 176 The wastewater should be stored in a specially built facility and then transported to a waste treatment facility before re-reinjection. However, most storage facilities are open pits where dissolved gas and petroleum components can evaporate, liners leak. Overflow after rainfalls can also occur, leading to ground contamination and can catch fire with lightning because of the petroleum components. 177 There are a number of fracking water spillage incidents which happened in many places in the USA resulting in loss of livestock and environmental damage over vast tracks of land. 178 These serious incidences can also happen anywhere in the EU where shale gas activities are taking place if not properly managed.

Water quality
Shale gas activities affect water through abstraction and chemical pollution and by flowback water. The abstraction depletes surface water resources whilst chemicals contaminate both surface water and groundwater. 179 HVHF uses very large volumes of water estimated at more than 15,000 m 3 per well, 180 for example at Lebien LE-2H well in Poland approximately 18,000 m 3 of water was used for drilling. 181 Drawing such large quantities of water may result in the depletion of water from the resources and affecting the environment depending on such resources. That can also create shortages of water supply to the communities using the same sources for their water supply. 182

Surface water
The Water Framework Directive (2000/60/EC) protects available water resources from depletion by setting out all water related impacts framework and promoting sustainable use of water. The abstraction of surface or groundwater sources has to be authorised; however, MS can exempt abstraction where impacts on water are assessed as insignificant. This is aimed at protecting both ground and surface waters and projected areas are enhanced and restored 183 including analysing human activities and the economics of the river basin and status of water bodies. 184 In making authorisation decisions competent authorities have to consider impacts from the use and intake of water affecting the river basin areas and should put measures in place to limit such impacts. MS are required to achieve the objectives of the Water Framework Directives by establishing a programme of measures for authorising, controlling the fresh water abstraction and impounding of groundwater. 185

Groundwater
Groundwater is water which is directly in contact with the ground or subsoil and in the saturation zone below the surface of the ground. This includes aquifers which are geological permeable strata that allow large quantities of groundwater to flow or abstract 186 and body of groundwater is a clearly noticeable volume of groundwater found in an aquifer. 187 Water Framework Directive 2000/60EC set out to prevent and reduce water pollution making sure water usage is sustainable, to protect the environment ecosystem improvements and floods and drought impact mitigation. This directive was adopted without taking into account the environmental impacts of shale gas which calls for the directive to be reviewed to accommodate shale gas activities. The IED addresses the risks of leakages through steel and cement constructed well bore risking environmental impact as happened in Germany in 2007 when wastewater pipes leaked contaminating groundwater sources with mercury and benzene. 189 The IED permits and a management plan is required under the Mining Waste Directive (2006/21/EC). There are also technical standards set up in the oil and gas industry which has to be followed in shale gas activities too, namely ISO 10426-1 which covers well cementing, ISO10405 for casings and ISO 11961 for Drill pipes. 190 The Recommendations are that there should be a minimum distance kept between water protection and residential areas from the authorised operational areas. A minimum vertical separation risk assessment should be done between the groundwater and areas to be fractured by maintaining minimum limitations of depth. 191 These distances are not defined in the recommendation leaving it out for the MS to do their own interpretation without clear uniform rules applicable across the EU resulting in MS coming up with different minimum numbers from each other. 192 A study carried out in September 2014 shows that people who leave in a distance of 1 km away from the wells are at risk of developing skin and upper respiratory problems than those who leave 2 km further away. 193 There is no any scientific evidence so far to conclude that safety of groundwater will be guaranteed by any limitations, but studies confirm that the drilling depth has nothing to do with groundwater contamination 194 but ageing, corrosion and poor cementing and earth tremors have been suggested to be risks almost unavoidable. 195 Despite the fact that there is no scientific evidence to the effect that depth limitations are linked to groundwater contamination, some states have introduced depth limitations. The UK February, 2015 Infrastructure bill states that fracking has to take place in not less than 1200 m away from the groundwater source, except where consent is sort from the Secretary of State. These measurements are taken from the surface putting the reserves at risk because they may be found at different depth and the 1200 limit might be too close in certain areas. 196 The UK has not yet set a buffer zone between residential areas and oil and gas development areas which are determined by local planning authorities and permits have been granted for drilling and testing in a groundwater source protection zone 2 area which is around 300 metres from Greater Manchester's, residential suburbs. 197 Poland's depth limitations are set at 5000 m as the distance which exploration drilling can be done without an assessment. 198 On the 15 February 2015 Poland was warned for breaching EU regulation by excluding EIA 199 which have now forced the Commission to refer Poland to the European court on the 28 April 2016 for failure to adequately assess exploratory mining drillings. 200 Poland included in its legislation a buffer zone minimum distance set from homes to fracking activities despite being advised to include in their legislation a 500 m minimum distance in their legislation. 201 In German fracking could be done near the groundwater zone and there is no buffer zone between the residential and authorised operational zones and the authorities reiterated that they would not consider all depends on the overall geological circumstances of each targeted area. 202 The other problem is that stored flowback water containing chemicals needs to be disposed properly without causing environmental impacts. 203 Water Framework Directive does not allow injection into the ground of flowback water with chemicals. This directive generally provides for the protection and conservation of groundwater but the specific groundwater pollution preventive measures are provided in the Groundwater Directive (2006/ 118/EC).
MS are under obligation to establish monitoring schemes through their competent authorities to prevent pollution of groundwater by limiting imputes of pollutants into groundwater and also to be able to notice any changes in the quality of the groundwater in the early stages. 204 This directive is indirectly applicable to the hydraulic fracturing impacts except on reasonably unforeseen accidents and natural causes. 205 The  207 but the pollution also comes from well heads gas flaring, gas leakages from compressors, evaporation of fracking chemicals from waste ponds during fracking and from underground. 208 Fracking has been concluded to be responsible to air pollution and the increase in benzene and many other toxic gases from carbohydrates and to be responsible of health issues ranging from eye irritations, sore throats and headaches including high risks of cancer. 209 Emission from fugitive methane can happen from the processing plants and on transportation and during the production phase contributing to local or regional air pollution with various health impacts. 210

Chemicals used in fracking
The CR 2014 failed to address all the shale gas potential impacts because the EU legislation was already there before the fracking activities stated in the EU. Regulation (EC) No 1907/2006 of the European Parliament and the council on registration, evaluation, authorisation and restriction of chemicals (REACH), and Regulation (EU) 528/2012 of the European Parliament and the Council, meant to promote the availability of chemical and biocidal products are applicable in hydraulic fracturing projects.
A wide variety of chemicals are contained in drilling muds and hydraulic fracturing fluids and registration of chemicals made or brought in the country in large quantities of 1000 tonnes is required as required by Directive 67/548/EEC.

Chemical registration
There is no transparency relating to the chemicals used in the hydraulic fracturing in shale gas projects. The EC gave the responsibility of checking transparency on the European Chemical Agency (ECHA) by advising MS to check on entities that manufacture, import and use hydraulic fracturing chemical substances to comply with the REACH regulation. This is to make sure that chemicals are declared and registered by adapting the REACH framework. On the other hand, ECHA announced that it was not compulsory for firms to highlight that chemicals are being used in their fracking activities and no action could be taken for failing to comply with the disclosure. 211 This means that the monitoring is left out for the companies themselves, which is a regulatory weakness. It is therefore difficult for the MS to make sure that operators publicise the chemical substances they use in their fracking as recommended by S15 (a) of 2014 CR if they do not know what chemicals combinations they use.
There has been so far no meaningful data imputing in the ECHA system since it has not been able to discriminate between useful and useless data and recently it has been announced that they are now doing a manual checking of information which could be a mammoth task which means so far the system has been defective. 212 The International Association of Oil and Gas Producers (IOGP) have their own initiative of voluntarily disclosing chemicals used on wells already fracked. This used by companies that are members of this association such as Cuadrilla for its EU operations, INEOS and Celtique's UK operations and a few others. Still this not enough because it is a voluntary exercise, subscribed by a few companies involved in the fracking business in the EU and their disclosures are for specific geographic areas and only done on projects that have already been fractured after 1 January 2011. 213 Some of these companies disclose for the whole of their EU operations, whilst some only disclose in certain states as indicated above. This also does not help in preventing chemical damage to the environment by disclosing chemicals that have been used already, which might have caused the damage already.
Disclosures can be viewed as a source of conflict of interests between chemical service companies who want to protect their intellectual property rights of the composition of the chemicals they use in fracking activities and the public's rights to be informed of the composition of chemicals used in fracking activities within their communities. 214 Section 9 of the CR 2014's recommendation is that operators should monitor their own activities at every stage of the wells' life, shifting the burden of proof from public authorities to operators. Another requirement is to do the testing of well integrity through well design, construction without specifying how frequently these tests should be carried out as they are required even after the well is shut. 215

Environmental liability
Environmental Liability Directive 2004/35/EC is a common framework for liability established by the EU for prevention of imminent threat of environmental damage and to provide remedies for any damages caused. The ''polluter pays'', principle is the basis of this directive which basically means that a person should be liable for remedial costs where damage is as a result of his fault. This was adopted into the EU law back in the Single European Act 1986, Article 130r (2). 216 This principle is now covered under Article 191 (2) 2 2TFEU emphasising that prevention and elimination of environmental damage should be paid for by the person who caused the damage. MS are required to take preventive measures as well as restorative action, in cases where the damage has already been done and then claim from the polluter for restoration cost. 217 It will be reasonable for operators to be obliged to secure financial guarantees to cover such eventualities as recommended by the CR rather than on a voluntary basis as per directive 204/35/EC. The Mining Waste Directive puts an obligation on operators to be responsible for monitoring; maintenance and making sure any measures are always in place even after the closure of the shale extraction activities.
The operator is obliged to notify the competent authority within 48 h of any significant environmental impacts noticed through the waste facility control and monitoring procedures and shall follow any instructions given by the authority in addition to operator's internal emergency plan implementation. 218 Article 7 of the Environmental Liability Directive provides the remedial measures to be determined and Article 5 provides for preventive actions available for the operator and the competent authorities for necessary measures to be taken to prevent damages. 219 The Directive also encourages MS to cooperate on preventive or remedial action where the threat of damage may affect more than one MS. 220 Personal restorative measures will be required from the operator, where damage has already occurred. A competent authority has the power to compel operators to the damaged environment as set out in Annex II to the Directive or recover costs of such restoration from the operator. This directive does not expressly refer to shale gas projects and it could have more impact if there is an express reference to shale gas. 4.5.9 Other directives 4.5.9.1 The emissions directive (IED) 2010/75/EC This directive was adopted on the 24 November 2010, repealed the Integrated Pollution Prevention and Control (IPPC) as from 7 January 2014. 221 The directive is aimed at achieving environmental protection at a higher level by integrating pollution control mechanisms on developers who pursue activities in the energy industries that emits into the air, water and land waste management. 222 Annex 1 of the directive includes industrial installations with a thermal rate of more than 50 MW. An installation is a unit which is technical and stationary for the purposes of dealing with any or a number of site activities that could emit and pollute the environment listed in Annex 1. 223 A drilling rig of 5400 horse power (HP) can roughly have an input of only 8 MW 224 which is far below the threshold of the Annex 1 above limits excluding combustion from single drilling rigs unless counted as multiple installations. 225 Hydraulic fracturing requires the construction of installations for disposal or recovery of hazardous waste as described in Article 1 (4) of the Directive 91/689/EEC, Council Directive as amended by Directive 2008/98/EC. Hydraulic fracturing process uses a lot of water and various chemicals in propping up shale gas. A threshold of hydraulic fracturing fluid classified as hazardous has been set by the EC decision 2000/532/EC.
An IED permit has to be obtained for the installations for disposing the hazardous substances 226 and non-hazardous waste material discharged at a rate of more than 50 tonnes per day. 227 Hazardous waste is material that contains a number of hazardous properties that is oxidising, toxic, flammable, corrosive, irritant and many other characteristics that are capable of generating into other substances hazardous waste material. 228 The IED Directive is applicable to installations on hydraulic fracturing projects that includes shale gas exploitation site as long as these installations meet the waste management criteria stipulated in Annex 1. 229

IED shortfall
Hydraulic fluids used can be commercially sensitive and its composition may be protected from disclosure of which different chemical compositions can be applied at different sites by different developers. 230 The non-disclosure commercial protection of the combination of chemicals used in fracking activities makes it difficult to determine how hazard the chemicals used will be. There should be an obligation of obtaining a permit on the whole site which is not provided for in the EU shale gas legislation.
Where a permit under the IED is required, monitoring of emissions to air will be stipulated in the permit and the competent authority is empowered to inspect and monitor compliancy as determined by individual MS. 231 The uncertainty of HVF technology's characteristics makes it difficult to conclude that the EU legislation in this respect is adequate. 232

Noise impact
A number of Directives are relevant in relation to the controlling of the noise impact some included in the general legislation discussed above, namely the EIA Directive (2011/92/EU, the SIA directive (2001/42/EC, the Noise Directive (2002/49/EC, the outdoor machinery noise directive (2000/14/EC) and the IED Directive (2008/1/EC). Under the EIA Directive, it is not mandatory to take measures on noise impact during drilling; however, it is the responsibility of the MS to make sure the relevant authority is furnished with the potential environmental impacts such as noise especially in hydrocarbons hydraulic fracturing operations.

The outdoor machinery noise
Much of the equipment used for HVHF has to meet certain defined noise levels before it is used on site. HVHF drilling equipment is not on the list of equipment covered in the Directive 2000/14/EC and compressors over 350kw are also excluded. This is a shortfall on the part of the EU legislation indicates that there are no noise limits from drilling activities for shale gas extraction and no mandatory steps to mitigate noise are given. 233

Conclusions
This article revealed a number of issues surround the EU's, ''soft law'', regulatory approach for shale gas activities including that it is a non-binding and a non-coherent recommendation. It would appear some of the HVHF risks at the surface appear to be prima facie addressed when examining some of the above provisions, but, however, there is a clear lack of coherent, comprehensive approach regarding SIA, EIA, baseline monitoring and reporting requirements, well integrity and chemicals disclosure. 234 The CR does not have the necessary power to compel EU MS to put efforts in setting up minimum standards in regulating shale gas activities and comprehend the need and importance of carrying out SIA and be able to assess the cumulative effects of shale gas activities. There is too much reliance in mitigating shale gas impacts by applying the conventional oil and gas industry's best practice and self-monitoring.
Member states are cherry picking what they want to apply on the recommendations and not using it as a basis of making their strong regulation for fracking. Some member states made it clear that they cannot afford or are illequipped to deal with certain fracking challenges. There is lack of monitoring capacity among MS for different reason including conflicts of interest and corrupt practices.
The public concerned with fracking activities are consulted only as a formality and not with the expectation of a constructive feedback that can be used in a decision making process of which they are either given short period to review complicated documents. Some states are just transposing the Recommendations in their regulatory framework just to convince the EU Commission that they are complying with the EU law and not taking seriously the impacts of the fracking.
The development of shale gas exploration and production is going to remain in the interest of many EU MS and the industry for some time. The legal, regulatory, policies and the natural settings will determine the ability of individual states to realise self-sufficiency from their local shale gas resources as well as the ability of the operators to economically manage the projects viably and make profits.
Projects have failed to take off in some MS, developers withdrawing after being licensed as witnessed in Poland where five companies, including ConocoPhillips and Exxon Mobil  out shale gas activities to the great disappointment to the Polish government. 235 Therefore, shale gas prices and speed of production volumes will be not good enough as compared to that of the USA and the costs of production are estimated to go up three times per unit of gas as compared to that of the USA. 236 There should not be too much excitement about the development of shale gas in the EU because it is not going to be business as usual.
The regulatory framework is failing to address the environmental concerns raised from shale gas activities which are not yet fully understood coupled by lack of regulatory confidence and public distrust. There have been a series of reports, comments, directive amendments and recommendations coming up with different ideas as to how shale gas legislation can be improved but so far there is lack of new smart rules which effectively addresses the key shale gas development concerns. The Commission, however, decided to take the softest regulatory policy which is cheaper to implement compared to other options available which has so far proved to be incapable of protecting the health and the environment from the impacts of SG activities.

Recommendations
The EU should make sure those high standards of transparency on project that may have cross-border impacts are implemented and strictly monitored SEA and EIA to be carried across borders whenever a trans-boundary project is carried out even if thresholds are different in both states. 237 There should be specific legal requirements of monitoring shale gas projects fracturing activities in all MS which so far only two EU countries, the UK and Denmark, put such provisions in their legislation. 238 Impacts from shale gas projects are localised in nature which makes local level regimes to be more relevant in determining the economic attractiveness of shale gas projects. There should be an adjoined up strategic thinking and cooperation between stakeholders and remove the fragmentation of regulatory approaches to develop public trust and confidence with the potential investors.
There are challenging compliancy monitoring and enforcement actions which should be prioritised in the EU. There are also practical challenges on the overlapping nature of the shale gas developing stages which complicates the interaction of all stakeholders throughout the development lifecycle. At this infant stage of the shale gas industry development, environmental and social regulatory risks will put pressure on operators as policy makers try to correct the deficiencies in the current legislation in shale gas practices and trying to achieve their nations' social needs.
The environmental impacts can be devastating in the communities where projects involving fracking are located therefore individual states should take more precautionary measures to safeguard their environment and the health of their citizens who may be affected with impact of the effects of shale gas exploration and production.
It should be the prerogative of MS to monitor all shale gas activities they authorise in their states than to delegate monitoring to the developers themselves by establishing national environmental inspectors who monitor the activities of operators on projects with potential impacts to the environment such as the shale gas extraction and production. Self-monitoring and self-regulation have proved to be very in effective and pushed the establishment of a social licence to operate much further.
Application of these regulations also comes at a price and some MS are already financially struggling and cannot afford to finance the management process of authorisations, permits and monitoring as required and then. This all points out to the conclusion that regulation of shale gas activities impacts cannot be said to be fit for purpose in the EU at the moment.
