27

The referring court notes that, out of 162 Natura 2000 sites in the Netherlands, 118 face a problem of excessive nitrogen deposition, for which the principal national source of emissions is agriculture.

| 28 | The referring court observes that this excessive nitrogen deposition poses a problem for achieving the conservation objectives of nitrogen‐sensitive natural resources in Natura 2000 sites. In particular, significant deposition leads to the formation of a nitrogen cover, as a result of which, in many regions, the so-called ‘critical’ deposition values for the habitat types designated have been substantially exceeded. Exceeding the critical deposition value means that the risk of the quality of habitat types being negatively affected by the acidifying and eutrophying effects of nitrogen deposition cannot be ruled out in advance. |

| 30 | The aim of the PAS is twofold. It is intended, first, to conserve and, where necessary, restore the Natura 2000 sites listed by it in order to achieve a favourable conservation status at national level and, secondly, to enable the maintenance or development of economic activities that are sources of nitrogen deposition in those sites. The PAS is also based upon the premiss that nitrogen deposition will be reduced and half of that reduction will offer ‘room for deposition’ for new economic activities. |

| 31 | The method underlying the PAS is based on ascertaining critical deposition values for each Natura 2000 site and for the habitat types identified.

| 33 | The referring court explains that the PAS also includes site-specific restoration measures, such as hydrological measures and supplementary measures to the benefit of vegetation, as well as source-directed measures, such as those covering stables, low-emission fertilisation methods, feed measures and management measures. Those measures make it possible to envisage an improvement in natural resistance and an additional reduction in nitrogen deposition compared with the reduction already achieved by means of external measures adopted outside of the PAS and enabling autonomous reduction. |

| 34 | The referring court further states that, for authorisation procedures, the regulation accompanying the PAS draws a distinction between three categories of projects. First, the need to obtain authorisation does not apply where it is a project or another act which causes nitrogen deposition of less than 0.05 mol N/ha/yr. Secondly, projects and other acts causing nitrogen deposition of more than 0.05 mol N/ha/yr but less than 1 mol N/ha/yr are also permitted without prior authorisation, but they must necessarily be notified. Thirdly, projects and other acts causing nitrogen deposition exceeding the threshold of 1 mol N/ha/yr are entirely subject to the permit requirement. |

| 35 | In the latter instance, the assessing authority must examine whether the activity for which such a request has been made would cause an increase in nitrogen deposition. In that regard, the decisive factor is whether the situation created by the new project or new activity causes an increase in deposition compared with the situation prior to the issuing of a permit or compared with the highest level of deposition actually caused in the period between 1 January 2012 and 31 December 2014. If the planned project or operation does not cause an increase in nitrogen deposition, the authority may issue authorisation under the Nbw 1998 by reference to the appropriate assessment upon which the PAS is based. In that case, the deposition caused by the planned project or operation forms part of the deposition analysed in that appropriate assessment. If that project or operation causes an increase in nitrogen deposition, the competent authority may issue authorisation if room for development is available for that purpose. |

| 36 | An impact assessment of those measures has shown that nitrogen deposition will decrease by about 13.4 kilotonnes per year from now until 2020, as compared to the situation if a programme like the PAS had not been implemented. In order to allow a safety margin, only 6.4 kilotonnes per year are taken into consideration in the PAS. With regard to the room for development, a maximum of 60% may be allocated during the first three years of the PAS and 40% may be allocated during the second half of its duration. |

It also permanently registers the room for deposition and room for development available for each site covered by the PAS. |

Stichting Werkgroep Behoud de Peel brought an appeal against the six authorisations at issue because it considers that the Provincial Government of Noord-Brabant could not issue them under the national legislation, in so far as it is not a correct transposition of Article 6 of the Habitats Directive.

| 45 | In that regard, the environmental conservation association claims, first of all, that a programme may not replace the individual assessment required by Article 6(3) of that directive for projects which may have a significant effect on Natura 2000 sites. It further claims that deposition below the threshold value or limit value set by the national legislation may have significant effects. It adds that the appropriate assessment on which the PAS is based fails to comply with that directive, Article 6(1) and (2) of which require the adoption of appropriate conservation measures. Moreover, it considers that the assessment includes source‐directed measures and restoration measures which are compensatory in nature and, finally, deems it incompatible with Article 6 of the Habitats Directive that room for development may be allocated before the measures have had any positive effects. |

| 47 | For all of those sites, the authors of the assessment at issue researched whether, from a scientific perspective, there was no reasonable doubt as to whether, notwithstanding the allocation of room for deposition and room for development to the projects and activities, and taking account of the source-directed measures and restoration measures in the PAS, the objectives of conserving nitrogen-sensitive ecological features would be achieved and that the conservation thereof would be ensured. The room for deposition and room for development allocated for all of the projects and activities made possible by the PAS were appropriately assessed. It follows from that assessment that the quality of the habitat types will not deteriorate and that the natural features of the Natura 2000 sites will not be adversely affected. |

Case C-293/17

Case C-293/17

| 50 | By decision of 23 June 2015, the Provincial Government of Gelderland rejected as unfounded the complaint brought by environmental conservation associations, namely Coöperatie Mobilisation for the Environment UA and Vereniging Leefmilieu, against that government’s decision not to penalise the activities of a livestock business causing nitrogen deposition on Natura 2000 sites. By three decisions of 14 July 2015, the Provincial Government of Limburg also rejected as unfounded similar complaints in respect of identical activities. The disputes before the referring court concern those four decisions. |

By three decisions of 14 July 2015, the Provincial Government of Limburg also rejected as unfounded similar complaints in respect of identical activities. The disputes before the referring court concern those four decisions.

| 51 | As the exemption from the permit requirement for the grazing of cattle and the application of fertilisers on the surface of land and below its surface entered into force only after the adoption of those decisions, namely, first, under the Nbw 1998 and, after 1 January 2017, under the Wnb, the Provincial Governments have requested that account be taken of that legislation when the appeals are dealt with. According to the referring court, those appeals must in fact be examined on the basis of the Environmental Decree of the Provincial Government of Gelderland and the Environmental Decree of the Provincial Government of Limburg. It further states that the appropriate assessment on which the exemption laid down in those decrees is based is the assessment conducted for the purposes of the PAS in its entirety. |

| 52 | Coöperatie Mobilisation for the Environment UA and Vereniging Leefmilieu claim before the referring court that the activities of agricultural undertakings are likely to have a deteriorative effect on the quality of the habitat and are, therefore, subject to the obligation to obtain a permit pursuant to Article 19d(1) of the Nbw 1998. |

| 53 | The Provincial Governments of Limburg and Gelderland contend that the grazing of cattle and application of fertilisers are admittedly ‘other operations’ within the meaning of Article 19d(1) of the Nbw 1998, but that no obligation to obtain a permit to carry out those activities stems from that provision because there is nothing to suggest that they will have effects on Natura 2000 sites. |

| 54 | Those governments observe that, according to the appropriate assessment conducted in view of adopting the PAS, it is ruled out that grazing and fertilising at the 2014 level could have significant effects, and that, on average, an increase in nitrogen deposition as a result of those activities may be ruled out after 2014. |

| 55 | More specifically, the Provincial Government of Limburg appears to rely on the consideration that both grazing and fertilising constitute ‘existing practices’ within the meaning of the Nbw 1998 and were therefore lawful before Article 6 of the Habitats Directive became applicable to the Natura 2000 sites concerned. |

| 56 | The referring court states that, other than the questions formulated in Case C‐294/17, the request for a preliminary ruling in Case C‐293/17 raises, first, the question whether the activity consisting in the grazing of cattle and application of fertilisers is to be classified as a project within the meaning of Article 6(3) of the Habitats Directive and whether it is compatible with Article 6(2) and (3) of that directive to grant an exemption allowing an undertaking to carry out such an activity without individual approval. Secondly, the referring court is uncertain whether, where it is the only appropriate measure allowing intervention in respect of existing or future activities which are likely to have a deteriorative effect on or damage a natural site significantly, the power to impose the obligations laid down in Article 2.4 of the Wnb is sufficient to ensure compliance with Article 6(2) of the Habitats Directive. |

Consideration of the questions referred

Consideration of the questions referred

The first question in Case C-293/17

The first question in Case C-293/17

| 59 | By the first question in Case C‐293/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as meaning that the grazing of cattle and the application of fertilisers on the surface of land or below its surface in the vicinity of Natura 2000 sites may be classified as a ‘project’ within the meaning of that provision, on the ground that they are likely to have significant consequences for those sites, even if those activities, in so far as they are not a physical intervention in the natural surroundings, do not constitute a ‘project’ within the meaning of Article 1(2)(a) of the EIA Directive. |
| --- | --- |

59

By the first question in Case C‐293/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as meaning that the grazing of cattle and the application of fertilisers on the surface of land or below its surface in the vicinity of Natura 2000 sites may be classified as a ‘project’ within the meaning of that provision, on the ground that they are likely to have significant consequences for those sites, even if those activities, in so far as they are not a physical intervention in the natural surroundings, do not constitute a ‘project’ within the meaning of Article 1(2)(a) of the EIA Directive.

| 60 | In the first place, it must be noted that, while the Habitats Directive does not define the concept of ‘project’, it is apparent from the Court’s case‐law that the definition of ‘project’ within the meaning of Article 1(2)(a) of the EIA Directive is relevant to defining the concept of project as provided for in the Habitats Directive (see, to that effect, judgment of 14 January 2010, Stadt Papenburg, C‐226/08, EU:C:2010:10, paragraph 38 and the case-law cited). |
| --- | --- |

60

In the first place, it must be noted that, while the Habitats Directive does not define the concept of ‘project’, it is apparent from the Court’s case‐law that the definition of ‘project’ within the meaning of Article 1(2)(a) of the EIA Directive is relevant to defining the concept of project as provided for in the Habitats Directive (see, to that effect, judgment of 14 January 2010, Stadt Papenburg, C‐226/08, EU:C:2010:10, paragraph 38 and the case-law cited).

| 61 | In the present case, the referring court is uncertain whether the grazing of cattle and the application of fertilisers on the surface of land or below its surface are to be included in the concept of ‘project’ within the meaning of Article 6(3) of the Habitats Directive, in so far as the Court has stated, in paragraph 24 of the judgment of 17 March 2011, Brussels Hoofdstedelijk Gewest and Others (C‐275/09, EU:C:2011:154), that the renewal of an existing permit cannot, in the absence of any works or interventions involving alterations to the physical aspect of the site, be classified as a ‘project’ within the meaning of the provisions preceding Article 1(2)(a) of the EIA Directive. |
| --- | --- |

61

In the present case, the referring court is uncertain whether the grazing of cattle and the application of fertilisers on the surface of land or below its surface are to be included in the concept of ‘project’ within the meaning of Article 6(3) of the Habitats Directive, in so far as the Court has stated, in paragraph 24 of the judgment of 17 March 2011, Brussels Hoofdstedelijk Gewest and Others (C‐275/09, EU:C:2011:154), that the renewal of an existing permit cannot, in the absence of any works or interventions involving alterations to the physical aspect of the site, be classified as a ‘project’ within the meaning of the provisions preceding Article 1(2)(a) of the EIA Directive.

| 62 | In that regard, it should be noted that, in that judgment, the Court, when it formulated the condition relating to the existence of works or interventions involving alterations to the physical aspect of the site, clarified the definition of the concept of ‘project’ within the meaning of Article 1(2) of Directive 85/337 and, in particular, the requirement for an ‘intervention in the natural surroundings’ contained therein. |
| --- | --- |

62

In that regard, it should be noted that, in that judgment, the Court, when it formulated the condition relating to the existence of works or interventions involving alterations to the physical aspect of the site, clarified the definition of the concept of ‘project’ within the meaning of Article 1(2) of Directive 85/337 and, in particular, the requirement for an ‘intervention in the natural surroundings’ contained therein.

| 63 | It must be noted that the requirements relating to ‘works’ or ‘interventions involving alterations to the physical aspect’ or even an ‘intervention in the natural surroundings’ are not to be found in Article 6(3) of the Habitats Directive, that provision requiring an appropriate assessment, inter alia where a project is likely to have a ‘significant’ effect on a site. |
| --- | --- |

63

It must be noted that the requirements relating to ‘works’ or ‘interventions involving alterations to the physical aspect’ or even an ‘intervention in the natural surroundings’ are not to be found in Article 6(3) of the Habitats Directive, that provision requiring an appropriate assessment, inter alia where a project is likely to have a ‘significant’ effect on a site.

| 64 | Thus, Article 1(2)(a) of the EIA Directive defines the concept of ‘project’ for the proposes of that provision, attaching to it conditions that are not specified in the equivalent provision of the Habitats Directive. |
| --- | --- |

64

Thus, Article 1(2)(a) of the EIA Directive defines the concept of ‘project’ for the proposes of that provision, attaching to it conditions that are not specified in the equivalent provision of the Habitats Directive.

| 65 | In the same vein, it follows from the Court’s case-law that, in so far as the definition of the concept of ‘project’ stemming from Directive 85/337 is more restrictive than that stemming from the Habitats Directive, if an activity is covered by Directive 85/337, it must, a fortiori, be covered the Habitats Directive (see, to that effect, judgment of 7 September 2004, Waddenvereniging and Vogelbeschermingsvereniging, C‐127/02, EU:C:2004:482, paragraphs 26 and 27). |

65

In the same vein, it follows from the Court’s case-law that, in so far as the definition of the concept of ‘project’ stemming from Directive 85/337 is more restrictive than that stemming from the Habitats Directive, if an activity is covered by Directive 85/337, it must, a fortiori, be covered the Habitats Directive (see, to that effect, judgment of 7 September 2004, Waddenvereniging and Vogelbeschermingsvereniging, C‐127/02, EU:C:2004:482, paragraphs 26 and 27).

| 66 | It follows that, if an activity is regarded as a ‘project’ within the meaning of the EIA Directive, it may constitute a ‘project’ within the meaning of the Habitats Directive. However, the mere fact that an activity may not be classified as a ‘project’ within the meaning of the EIA Directive does not suffice, in itself, to infer therefrom that the activity may not be covered by the concept of ‘project’ within the meaning of the Habitats Directive. |

However, the mere fact that an activity may not be classified as a ‘project’ within the meaning of the EIA Directive does not suffice, in itself, to infer therefrom that the activity may not be covered by the concept of ‘project’ within the meaning of the Habitats Directive.

| 67 | In the second place, in order to determine whether the grazing of cattle and the application of fertilisers on the surface of land or below its surface may be classified as a ‘project’ within the meaning of Article 6(3) of the Habitats Directive, it is important to examine whether such activities are likely to have a significant effect on a protected site. |

In the second place, in order to determine whether the grazing of cattle and the application of fertilisers on the surface of land or below its surface may be classified as a ‘project’ within the meaning of Article 6(3) of the Habitats Directive, it is important to examine whether such activities are likely to have a significant effect on a protected site.

| 68 | The 10th recital of the Habitats Directive states that an appropriate assessment must be made of any plan or programme likely to have a significant effect on the conservation objectives of a site which has been designated or is designated in future. That recital finds expression in Article 6(3) of the directive, which provides, inter alia, that a plan or project likely to have a significant effect on the site concerned cannot be authorised without a prior assessment of its implications for that site (judgment of 12 April 2018, People Over Wind and Sweetman, C‐323/17, EU:C:2018:244, paragraph 28 and the case-law cited). |

| 69 | In the present case, it is apparent from the findings of the referring court, described in paragraph 27 of the present judgment, that a large number of Natura 2000 sites in the Netherlands face a problem of excessive nitrogen deposition, and that the principal national source of emissions is the agricultural sector. |

In the present case, it is apparent from the findings of the referring court, described in paragraph 27 of the present judgment, that a large number of Natura 2000 sites in the Netherlands face a problem of excessive nitrogen deposition, and that the principal national source of emissions is the agricultural sector.

| 70 | In that context, as the Advocate General noted in points 117 and 126 of her Opinion, it is important to examine whether activities such as the application of fertilisers on the surface of land or below its surface and the grazing of cattle are compatible with the conservation objectives of the protected sites in the provinces of Gelderland and Limburg or whether they may have a significant effect on those sites. |

| 71 | Moreover, as the Advocate General noted, in essence, in paragraph 118 of her Opinion, it cannot be ruled out that the grazing of cattle and the application of fertilisers on the surface of land or below its surface are covered, in any event, by the concept of ‘project’ within the meaning of Article 1(2)(a) of the EIA Directive. |

| 72 | As regards the application of fertilisers, such an activity may alter the properties of the soil by enriching it with nutrients and thus constitute an intervention involving alterations to the physical aspect of the site within the meaning of Article 1(2)(a) of the EIA Directive and, with regard to the grazing of cattle, establishing grazing land could constitute ‘the execution of construction works or of other installations or schemes’ within the meaning of that provision, in particular if such execution involves, in the circumstances of the present case, an unavoidable or planned development of such grazing land, which it is for the referring court to verify. |

As regards the application of fertilisers, such an activity may alter the properties of the soil by enriching it with nutrients and thus constitute an intervention involving alterations to the physical aspect of the site within the meaning of Article 1(2)(a) of the EIA Directive and, with regard to the grazing of cattle, establishing grazing land could constitute ‘the execution of construction works or of other installations or schemes’ within the meaning of that provision, in particular if such execution involves, in the circumstances of the present case, an unavoidable or planned development of such grazing land, which it is for the referring court to verify.

| 73 | In the light of the foregoing, the answer to the first question in Case C‐293/17 is that Article 6(3) of the Habitats Directive must be interpreted as meaning that the grazing of cattle and the application of fertilisers on the surface of land or below its surface in the vicinity of Natura 2000 sites may be classified as a ‘project’ within the meaning of that provision, even if those activities, in so far as they are not a physical intervention in the natural surroundings, do not constitute a ‘project’ within the meaning of Article 1(2)(a) of the EIA Directive. |

The second question in Case C-293/17

The second question in Case C-293/17

| 74 | By the second question in Case C-293/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as meaning that a recurring activity, such as the application of fertilisers on the surface of land or below its surface, authorised under national law before the entry into force of that directive, may be regarded as one and the same project for the purposes of that provision, with the result that that activity does not fall within the scope of that provision. |

By the second question in Case C-293/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as meaning that a recurring activity, such as the application of fertilisers on the surface of land or below its surface, authorised under national law before the entry into force of that directive, may be regarded as one and the same project for the purposes of that provision, with the result that that activity does not fall within the scope of that provision.

| 75 | In order to answer the referring court’s questions, it should be recalled that, under the first sentence of Article 6(3) of the Habitats Directive, no project likely to have a significant effect on the site concerned can be authorised without a prior assessment of its implications for that site. |

In order to answer the referring court’s questions, it should be recalled that, under the first sentence of Article 6(3) of the Habitats Directive, no project likely to have a significant effect on the site concerned can be authorised without a prior assessment of its implications for that site.

| 76 | In so far as the application of fertilisers on the surface of land or below its surface in the vicinity of Natura 2000 sites may be classified as a ‘project’ within the meaning of Article 6(3) of the Habitats Directive, it is necessary to examine the bearing on the applicability of that provision of the fact that that recurring activity was authorised under national law before the entry into force of that directive. |

76

In so far as the application of fertilisers on the surface of land or below its surface in the vicinity of Natura 2000 sites may be classified as a ‘project’ within the meaning of Article 6(3) of the Habitats Directive, it is necessary to examine the bearing on the applicability of that provision of the fact that that recurring activity was authorised under national law before the entry into force of that directive.

| 77 | In that regard, the Court has previously held that such a fact does not in itself constitute an obstacle to considering such an activity, at the time of each subsequent intervention, as a distinct project within the meaning of that directive, at the risk of automatically excluding that activity from any prior assessment of its implications for the site concerned within the meaning of Article 6(3) (see, to that effect, judgment of 14 January 2010, Stadt Papenburg, C‐226/08, EU:C:2010:10, paragraphs 41 and 42). |

| 78 | However, if, having regard in particular to their regularity or nature or the conditions under which they are carried out, certain activities must be regarded as constituting a single operation, those activities can be considered to be one and the same project within the meaning of Article 6(3) of the Habitats Directive (see, to that effect, judgment of 14 January 2010, Stadt Papenburg, C‐226/08, EU:C:2010:10, paragraph 47). |

| 79 | In the present case, as the Advocate General noted in points 132 to 134 of her Opinion, the regular fertilising of agricultural land generally has a single common purpose, namely crop cultivation on a farm, and may constitute a single operation, characterised, in the pursuit of that common purpose, by the continuity of that activity in the same locations and under the same conditions. |

In the present case, as the Advocate General noted in points 132 to 134 of her Opinion, the regular fertilising of agricultural land generally has a single common purpose, namely crop cultivation on a farm, and may constitute a single operation, characterised, in the pursuit of that common purpose, by the continuity of that activity in the same locations and under the same conditions.

| 80 | In those circumstances, such a single operation, authorised and regularly practised before Article 6(3) of the Habitats Directive became applicable to the site at issue, may constitute one and the same project for the purposes of that provision, exempted from a new authorisation procedure. |

80

In those circumstances, such a single operation, authorised and regularly practised before Article 6(3) of the Habitats Directive became applicable to the site at issue, may constitute one and the same project for the purposes of that provision, exempted from a new authorisation procedure.

| 81 | The referring court is uncertain, however, as to the bearing on the applicability of Article 6(3) of the Habitats Directive and, accordingly, the requirement of an ‘appropriate assessment’ within the meaning of that provision, of the fact that, first, fertilising takes place on different plots of land, in variable quantities and following various techniques, which themselves evolve over time as a result of technical and regulatory changes, and, secondly, nitrogen deposition caused by the application of fertilisers has not, overall, increased after the entry into force of that provision. |

| 82 | In that regard, it should be noted that Article 6(3) of the Habitats Directive integrates the precautionary principle and makes it possible to prevent in an effective manner adverse effects on the integrity of protected sites as a result of the plans or projects being considered (judgment of 17 April 2018, Commission v Poland (Białowieża Forest), C‐441/17, EU:C:2018:255, paragraph 118 and the case-law cited). Thus, according to the Court’s settled case-law, recalled in paragraph 68 of the present judgment, the decisive criterion for establishing whether a new project requires an appropriate assessment of its implications to be carried out is whether there is a possibility that that project will have a significant effect on a protected site. |

Thus, according to the Court’s settled case-law, recalled in paragraph 68 of the present judgment, the decisive criterion for establishing whether a new project requires an appropriate assessment of its implications to be carried out is whether there is a possibility that that project will have a significant effect on a protected site.

| 83 | Consequently, where there is no continuity and, inter alia, the location and the conditions in which it carried out are not the same, the recurring activity of applying fertilisers on the surface of land or below its surface cannot be classified as one and the same project for the purposes of Article 6(3) of the Habitats Directive. It might be a case of new projects requiring an appropriate assessment within the meaning of that provision, the decision as to the obligation to conduct such an assessment depending, in each case, on the criterion relating to the risk of a significant adverse effect on the protected site on account of the changes thus brought about by such an activity. |

| 84 | Therefore, the fact that nitrogen deposition caused by the application of fertilisers on the surface of land or below its surface has not, as a whole, increased since the entry into force of Article 6(3) of the Habitats Directive is irrelevant to the question whether a new project requires an appropriate assessment to be carried out, in so far as that fact does not make it possible to rule out the risk that nitrogen deposition on the protected sites concerned has increased and that it now affects one of those sites significantly. |

| 85 | It must also be added that, even if a project was authorised before the system of protection laid down by the Habitats Directive became applicable to the site in question and, accordingly, such a project was not subject to the requirements relating to the procedure for prior assessment according to Article 6(3) of that directive, its implementation nevertheless falls within the scope of Article 6(2) of that directive. More specifically, an activity complies with Article 6(2) of the Habitats Directive only if it is guaranteed that it will not cause any disturbance likely significantly to affect the objectives of that directive, particularly its conservation objectives. The very existence of a probability or risk that an activity on a protected site might cause significant disturbances is capable of constituting an infringement of that provision (see, to that effect, judgment of 14 January 2016, Grüne Liga Sachsen and Others, C‐399/14, EU:C:2016:10, paragraphs 33, 41 and 42 and the case-law cited). |

| 86 | In the light of the foregoing, the answer to the second question in Case C-293/17 is that Article 6(3) of the Habitats Directive must be interpreted as meaning that a recurring activity, such as the application of fertilisers on the surface of land or below its surface, authorised under national law before the entry into force of that directive, may be regarded as one and the same project for the purposes of that provision, exempted from a new authorisation procedure, in so far as it constitutes a single operation characterised by a common purpose, continuity and, inter alia, the location and the conditions in which it is carried out being the same. If a single project was authorised before the system of protection laid down by that provision became applicable to the site in question, the carrying out of that project may nevertheless fall within the scope of Article 6(2) of that directive. |

The second question in Case C-294/17

The second question in Case C-294/17

| 87 | As a preliminary point, it should be recalled that, while Article 6(2) and Article 6(3) are designed to ensure the same level of protection (judgment of 12 April 2018, People Over Wind and Sweetman, C‐323/17, EU:C:2018:244, paragraph 24 and the case-law cited), the subject matter of those two provisions is different, in that the first is intended to introduce preventive measures whereas the second establishes an assessment procedure intended to ensure, by means of a prior examination, that a plan or project not directly connected with or necessary to the management of the site concerned but likely to have a significant effect on it is authorised only to the extent that it will not adversely affect the integrity of that site (judgment of 17 April 2018, Commission v Poland (Białowieża Forest), C‐441/17, EU:C:2018:255, paragraph 108 and the case-law cited). |

The uncertainty of the referring court thus concerns Article 6(3) of the Habitats Directive.

| 90 | By the second question in Case C-294/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as precluding national programmatic legislation which allows the competent authorities to authorise projects on the basis of an ‘appropriate assessment’ within the meaning of that provision, carried out in advance and in which a specific overall amount of nitrogen deposition has been deemed compatible with that legislation’s objectives of protection. |

| 91 | As recalled in paragraph 87 of the present judgment, Article 6(3) of the Habitats Directive establishes an assessment procedure intended to ensure, by means of a prior examination, that a project not directly connected with or necessary to the management of the site concerned but likely to have a significant effect on it is authorised only to the extent that it will not adversely affect the integrity of that site. |

| 92 | The first stage of the assessment procedure, envisaged in the provision’s first sentence, requires the Member States to carry out an appropriate assessment of the implications for a protected site of a plan or project when there is a likelihood that the plan or project will have a significant effect on that site (judgment of 21 July 2016, Orleans and Others, C‐387/15 and C‐388/15, EU:C:2016:583, paragraph 44 and the case-law cited). |

| 93 | Having regard to the precautionary principle, where a plan or project not directly connected with or necessary to the management of a site may undermine the site’s conservation objectives, it must be considered likely to have a significant effect on that site. The assessment of that risk must be made in the light inter alia of the characteristics and specific environmental conditions of the site concerned by such a plan or project (judgment of 17 April 2018, Commission v Poland (Białowieża Forest), C‐441/17, EU:C:2018:255, paragraph 112 and the case-law cited). |

As the Advocate General noted in point 40 of her Opinion, the first sentence of Article 6(3) of the Habitats Directive generally requires the individual assessment of plans and projects.

| 95 | Nonetheless, the appropriate assessment of the implications of the plan or project for the site concerned implies that all the aspects of the plan or project which can, either individually or in combination with other plans or projects, affect the conservation objectives of that site must be identified (judgment of 25 July 2018, Grace and Sweetman, C‐164/17, EU:C:2018:593, paragraph 40 and the case-law cited). |

| 96 | In that regard, as the Advocate General noted in points 42 to 44 of her Opinion, an overall evaluation of the implications carried out in advance, such as that conducted when the PAS was adopted, makes it possible to examine the cumulative effects of different sources of nitrogen deposition on the sites concerned. |

| 97 | The fact that an assessment at such a level of generality makes it possible to examine better the cumulative effects of various projects does not mean, however, that national legislation such as that at issue in the main proceedings necessarily meets all the requirements stemming from Article 6(3) of the Habitats Directive. |

| 101 | In order to ensure that all the requirements thus recalled are fulfilled, it is for the national courts to carry out a thorough and in‐depth examination of the scientific soundness of the ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive accompanying a programmatic approach and the various arrangements for implementing it, including inter alia the use of software such as that at issue in the main proceedings intended to contribute to the authorisation process. The competent national authorities may be entitled to authorise such an individual project on the basis of such an assessment only if the national court is satisfied that that assessment carried out in advance meets those requirements in respect of each specific individual project. |

The competent national authorities may be entitled to authorise such an individual project on the basis of such an assessment only if the national court is satisfied that that assessment carried out in advance meets those requirements in respect of each specific individual project.

| 102 | In this regard, it should be noted that under Article 1(e) of the Habitats Directive, the conservation status of a natural habitat is considered to be ‘favourable’ when, inter alia, its natural range and the areas it covers within that range are stable or increasing and the specific structure and functions which are necessary for its long-term maintenance exist and are likely to continue to exist for the foreseeable future. |

| 104 | In the light of the foregoing, the answer to the second question in Case C‐294/17 is that Article 6(3) of the Habitats Directive must be interpreted as not precluding national programmatic legislation which allows the competent authorities to authorise projects on the basis of an ‘appropriate assessment’ within the meaning of that provision, carried out in advance and in which a specific overall amount of nitrogen deposition has been deemed compatible with that legislation’s objectives of protection. That is so, however, only in so far as a thorough and in-depth examination of the scientific soundness of that assessment makes it possible to ensure that there is no reasonable scientific doubt as to the absence of adverse effects of each plan or project on the integrity of the site concerned, which it is for the national court to ascertain. |

The first question in Case C-294/17

The first question in Case C-294/17

| 105 | By the first question in Case C-294/17, the referring court asks, in essence, whether Article 6(2) and (3) of the Habitats Directive must be interpreted as precluding national programmatic legislation, such as that at issue in the main proceedings, exempting certain projects which do not exceed a certain threshold value or a certain limit value in terms of nitrogen deposition from the requirement for individual approval, since the cumulative effects of all the plans or projects likely to create such deposition were subject in advance to an ‘appropriate assessment’ within the meaning of Article 6(3) of that directive. |

| 106 | For the same reasons as those set out in paragraphs 87 to 89 of the present judgment, that question will be answered solely in the light of Article 6(3) of the Habitats Directive. |

106

For the same reasons as those set out in paragraphs 87 to 89 of the present judgment, that question will be answered solely in the light of Article 6(3) of the Habitats Directive.

| 107 | In the case in the main proceedings, the need to obtain authorisation does not apply, first, where a project causes nitrogen deposition of less than 0.05 mol N/ha/yr. Secondly, projects causing nitrogen deposition of more than 0.05 mol N/ha/yr but less than 1 mol N/ha/yr are also permitted without prior authorisation, but must necessarily be notified. |

Secondly, projects causing nitrogen deposition of more than 0.05 mol N/ha/yr but less than 1 mol N/ha/yr are also permitted without prior authorisation, but must necessarily be notified.

| 108 | In the present case, even though, in those two situations, the projects proposed would be exempted from authorisation, the authorisation scheme for them is based on the ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive, carried out when the PAS was adopted, in which the effects of plans or projects of that scale were examined. |

In the present case, even though, in those two situations, the projects proposed would be exempted from authorisation, the authorisation scheme for them is based on the ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive, carried out when the PAS was adopted, in which the effects of plans or projects of that scale were examined.

| 109 | The Court has held that, where a Member State introduces an authorisation scheme, under which there is no provision for a risk assessment depending inter alia on the characteristics and specific environmental conditions of the site concerned, that Member State must show that the provisions which it has adopted enable it to be excluded, on the basis of objective information, that any plan or project subject to that authorisation scheme will have a significant effect on a Natura 2000 site, whether individually or in combination with other plans or projects. It can be inferred from Article 6(3) of the Habitats Directive that competent national authorities may refrain from carrying out an impact assessment of any plan or project which is not directly connected with, or necessary to, the management of a Natura 2000 site only where it can be excluded, on the basis of objective information, that that plan or project will have a significant effect on that site, whether individually or in combination with other plans or projects (see, to that effect, judgment of 26 May 2011, Commission v Belgium, C‐538/09, EU:C:2011:349, paragraphs 52 and 53 and the case-law cited). |

The third and fourth questions in Case C-293/17

The third and fourth questions in Case C-293/17

| 113 | By the third and fourth questions in Case C-293/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as not precluding national legislation, such as that at issue in the main proceedings, which allows a certain category of projects, in the present case the application of fertilisers on the surface of land or below its surface and the grazing of cattle, to be implemented without being subject to a permit requirement and, accordingly, to an individualised appropriate assessment of its implications for the sites concerned, since that legislation is itself based on an ‘appropriate assessment’ within the meaning of that provision. |

By the third and fourth questions in Case C-293/17, the referring court asks, in essence, whether Article 6(3) of the Habitats Directive must be interpreted as not precluding national legislation, such as that at issue in the main proceedings, which allows a certain category of projects, in the present case the application of fertilisers on the surface of land or below its surface and the grazing of cattle, to be implemented without being subject to a permit requirement and, accordingly, to an individualised appropriate assessment of its implications for the sites concerned, since that legislation is itself based on an ‘appropriate assessment’ within the meaning of that provision.

| 114 | According to the Court’s case-law, the condition governing the need to undertake an assessment of the implications of a plan or a project on a particular site, in accordance with which such an assessment must be carried out where there are doubts as to the existence of significant effects, does not permit that assessment to be avoided, in respect of certain categories of plans or projects, on the basis of criteria which do not adequately ensure that those projects are not likely to have a significant effect on the protected sites. The option of generally exempting certain activities, in accordance with the rules in force, from the need for an assessment of their implications for the site concerned is not such as to guarantee that those activities do not adversely affect the integrity of the protected site. Thus, Article 6(3) of the Habitats Directive does not authorise a Member State to enact national legislation which allows the environmental impact assessment obligation for certain types of plans or projects to benefit from a general waiver (see, to that effect, judgment of 26 May 2011, Commission v Belgium, C‐538/09, EU:C:2011:349, paragraphs 41 to 43 and the case-law cited). |

| 115 | It follows that, as the Advocate General noted in point 144 of her Opinion, should the grazing of cattle and the application of fertilisers on the surface of land or below its surface constitute ‘projects’ within the meaning of Article 6(3) of the Habitats Directive, dispensing with the appropriate assessment of the implications of those projects for the site concerned may be compatible with the requirements stemming from that provision only if it is ensured that those activities cause no disturbance likely significantly to affect the objectives of that directive (see, to that effect, judgment of 4 March 2010, Commission v France, C‐241/08, EU:C:2010:114, paragraph 32). |

| 116 | In the present case, the referring court states that the authors of the appropriate assessment at issue in the main proceedings based it, inter alia, on the expected extent and intensity of the agricultural activities concerned and concluded that, for the level at which they were carried out at the time of that assessment, it could be ruled out that such activities would have significant consequences, and that, on average, an increase in nitrogen deposition caused by those activities could be ruled out. It likewise notes that the categorical exemptions at issue in the main proceedings mean that the activities concerned may be carried out regardless of the location and regardless of the nitrogen deposition that they cause. |

| 117 | In accordance with the Court’s case-law recalled in paragraph 98 of the present judgment, the assessment carried out under the first sentence of Article 6(3) of the Habitats Directive cannot have lacunae and must contain complete, precise and definitive findings and conclusions capable of removing all reasonable scientific doubt as to the effects of the plans or the projects proposed on the protected site concerned. |

| 118 | In those circumstances, as the Advocate General also noted, in essence, in points 146, 147 and 150 of her Opinion, it does not appear possible for the adverse effects of the projects at issue in the main proceedings on the integrity of the sites concerned to be removed beyond all reasonable scientific doubt, which it is for the referring court to ascertain. |

| 119 | An average value is not, in principle, capable of ensuring that there are no significant effects on any single protected site as a result of fertilising or grazing, as such effects seem to depend, inter alia, on the extent and, as the case may be, the intensiveness of those activities, the proximity which may exist between the place in which those activities are carried out and the protected site concerned, and specific conditions, for example owing to the interaction of other sources of nitrogen, potentially characterising that site. |

The fifth to seventh questions in Case C-293/17 and the third to fifth questions in Case C-294/17

| 121 | By the fifth to seventh questions in Case C-293/17 and the third to fifth questions in Case C-294/17, the referring court asks, in essence, whether, and under which conditions, an ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive may take into account the existence of ‘conservation measures’ within the meaning of paragraph 1 of that article, ‘preventive measures’ within the meaning of paragraph 2 of that article, measures specifically adopted for a programme such as that at issue in the main proceedings or ‘autonomous’ measures, in so far as those measures are not part of that programme. |

By the fifth to seventh questions in Case C-293/17 and the third to fifth questions in Case C-294/17, the referring court asks, in essence, whether, and under which conditions, an ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive may take into account the existence of ‘conservation measures’ within the meaning of paragraph 1 of that article, ‘preventive measures’ within the meaning of paragraph 2 of that article, measures specifically adopted for a programme such as that at issue in the main proceedings or ‘autonomous’ measures, in so far as those measures are not part of that programme.

| 122 | In particular, the referring court is uncertain whether such types of measures may be taken into account in an ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive only if they have already been adopted and have yielded results. |

122

In particular, the referring court is uncertain whether such types of measures may be taken into account in an ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive only if they have already been adopted and have yielded results.

| 123 | In that regard, it should be noted that it would be contrary to the effectiveness of Article 6(1) and (2) of the Habitats Directive for the effects of necessary measures under those provisions to be invoked in order to grant, under paragraph 3 of that article, the authorisation of a plan or project which has implications for the site concerned before they are actually implemented (see, to that effect, judgment of 17 April 2018, Commission v Poland (Białowieża Forest), C‐441/17, EU:C:2018:255, paragraph 213). |

Nor can the positive effects of the necessary measures under paragraphs 1 and 2 of Article 6 of the Habitats Directive be invoked in order to grant, under paragraph 3 of that article, authorisation to projects which have an adverse effect on protected sites.

| 125 | Furthermore, it must be added that, as follows from the judgments of 15 May 2014, Briels and Others (C‐521/12, EU:C:2014:330), and of 21 July 2016, Orleans and Others (C‐387/15 and C‐388/15, EU:C:2016:583), the case-law relating to Article 6 of the Habitats Directive requires a distinction to be drawn between protective measures forming part of the plan or project at issue and intended to avoid or reduce any direct adverse effects caused by it, in order to ensure that that plan or project does not adversely affect the integrity of the sites concerned, which are covered by Article 6(3), and measures which, in accordance with Article 6(4), are aimed at compensating for the negative effects of the plan or project on that site and cannot be taken into account in the assessment of the implications of that plan or project on that site (see, to that effect, judgment of 25 July 2018, Grace and Sweetman, C‐164/17, EU:C:2018:593, paragraph 47 and the case‐law cited). |

Furthermore, it must be added that, as follows from the judgments of 15 May 2014, Briels and Others (C‐521/12, EU:C:2014:330), and of 21 July 2016, Orleans and Others (C‐387/15 and C‐388/15, EU:C:2016:583), the case-law relating to Article 6 of the Habitats Directive requires a distinction to be drawn between protective measures forming part of the plan or project at issue and intended to avoid or reduce any direct adverse effects caused by it, in order to ensure that that plan or project does not adversely affect the integrity of the sites concerned, which are covered by Article 6(3), and measures which, in accordance with Article 6(4), are aimed at compensating for the negative effects of the plan or project on that site and cannot be taken into account in the assessment of the implications of that plan or project on that site (see, to that effect, judgment of 25 July 2018, Grace and Sweetman, C‐164/17, EU:C:2018:593, paragraph 47 and the case‐law cited).

| 126 | Moreover, according to the Court’s case-law, it is only when it is sufficiently certain that a measure will make an effective contribution to avoiding harm to the integrity of the site concerned, by guaranteeing beyond all reasonable doubt that the plan or project at issue will not adversely affect the integrity of that site, that such a measure may be taken into consideration in the ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive (see, to that effect, judgments of 26 April 2017, Commission v Germany, C‐142/16, EU:C:2017:301, paragraph 38, and of 25 July 2018, Grace and Sweetman, C‐164/17, EU:C:2018:593, paragraph 51). |

| 127 | In the present case, the referring court notes, first, that the approach to the nitrogen problem adopted by the authors of the PAS is intended to reduce nitrogen deposition in Natura 2000 sites by means of measures in sites already affected which will take effect in the long term, it being understood that some of those measures may be taken only in the future and that others still must be regularly renewed. |

Secondly, the referring court states that the PAS provides for annual monitoring of both deposition development and the implementation progress and results of measures, and also adjustment where their result is less favourable than the estimate used as a basis by the authors of the appropriate assessment.

| 130 | The appropriate assessment of the implications of a plan or project for the sites concerned is not to take into account the future benefits of such ‘measures’ if those benefits are uncertain, inter alia because the procedures needed to accomplish them have not yet been carried out or because the level of scientific knowledge does not allow them to be identified or quantified with certainty. |

| 131 | It must be added that the ‘appropriate assessment’ within the meaning of Article 6(3) of the Habitats Directive must include not only the anticipated positive effects of those ‘measures’ but also the certain or potential adverse effects which may result from them (see, to that effect, judgment of 25 July 2018, Grace and Sweetman, C‐164/17, EU:C:2018:593, paragraph 53). |

In the light of the foregoing, the answer to the fifth to seventh questions in Case C-293/17 and the third to fifth questions in Case C-294/17 is that Article 6(3) of the Habitats Directive must be interpreted as meaning that an ‘appropriate assessment’ within the meaning of that provision may not take into account the existence of ‘conservation measures’ within the meaning of paragraph 1 of that article, ‘preventive measures’ within the meaning of paragraph 2 of that article, measures specifically adopted for a programme such as that at issue in the main proceedings or ‘autonomous’ measures, in so far as those measures are not part of that programme, if the expected benefits of those measures are not certain at the time of that assessment.

The eighth question in Case C-293/17

The eighth question in Case C-293/17

| 133 | By the eighth question in Case C-293/17, the referring court asks, in essence, whether Article 6(2) of the Habitats Directive must be interpreted as meaning that measures introduced by national legislation, such as that at issue in the main proceedings, including procedures for the surveillance and monitoring of farms whose activities cause nitrogen deposition and the possibility of imposing penalties, up to and including the closure of those farms, are sufficient for the purposes of complying with that provision. |

| 134 | In that regard, the Court has previously held that national legislation including procedures for intervention by the competent authorities that were merely reactive and not also preventive disregarded the scope of the obligations stemming from Article 6(2) of the Habitats Directive (see, to that effect, judgment of 13 December 2007, Commission v Ireland, C‐418/04, EU:C:2007:780, paragraphs 207 and 208). |

| 135 | In the present case, the legislation at issue in the main proceedings allows the authorities, having regard to conservation objectives, first, to impose measures both preventive and corrective. Secondly, that legislation also includes a power of coercion, also including the possibility of adopting urgent measures. |

In the present case, the legislation at issue in the main proceedings allows the authorities, having regard to conservation objectives, first, to impose measures both preventive and corrective. Secondly, that legislation also includes a power of coercion, also including the possibility of adopting urgent measures.

| 136 | Consequently, such legislation, in so far as it makes it possible to prevent the occurrence of a certain number of risks linked to the activities at issue, constitutes an appropriate step within the meaning of Article 6(2) of the Habitats Directive. |

| | 2. | Article 6(3) of Directive 92/43 must be interpreted as meaning that a recurring activity, such as the application of fertilisers on the surface of land or below its surface, authorised under national law before the entry into force of that directive, may be regarded as one and the same project for the purposes of that provision, exempted from a new authorisation procedure, in so far as it constitutes a single operation characterised by a common purpose, continuity and, inter alia, the location and the conditions in which it is carried out being the same. If a single project was authorised before the system of protection laid down by that provision became applicable to the site in question, the carrying out of that project may nevertheless fall within the scope of Article 6(2) of that directive. |

| | 3. | Article 6(3) of Directive 92/43 must be interpreted as not precluding national programmatic legislation which allows the competent authorities to authorise projects on the basis of an ‘appropriate assessment’ within the meaning of that provision, carried out in advance and in which a specific overall amount of nitrogen deposition has been deemed compatible with that legislation’s objectives of protection. That is so, however, only in so far as a thorough and in-depth examination of the scientific soundness of that assessment makes it possible to ensure that there is no reasonable scientific doubt as to the absence of adverse effects of each plan or project on the integrity of the site concerned, which it is for the national court to ascertain. |
