Judgment
1This reference for a preliminary ruling concerns the interpretation of Articles 10 EC, 12 EC, 23 EC, 25 EC, 49 EC and 90 EC
2The reference has been made in the context of proceedings between the Stadtgemeinde Frohnleiten (municipality of Frohnleiten) and the Gemeindebetriebe (municipal enterprise) Frohnleiten GmbH, on the one hand, and the Bundesminister für Land- und Forstwirtschaft, Umwelt und Wasserwirtschaft (Federal Minister for Agriculture, Forestry, the Environment and Water Management, the ‘Minister’), on the other, concerning the taxation of a deposit of waste coming from Italy at the Frohnleiten municipal waste disposal site.
Legal context
Community legislation
3Under Article 1 thereof, Council Regulation (EEC) No 259/93 of 1 February 1993 on the supervision and control of shipments of waste within, into and out of the European Community (OJ 1993 L 30, p. 1), as amended by Commission Regulation (EC) No 2557/2001 of 28 December 2001 (OJ 2001 L 349, p. 1) (‘Regulation No 259/93’), applies inter alia to shipments of waste within the Community.
4Articles 3 to 5 of Regulation No 259/93 lay down the procedure applicable to shipments between Member States of waste for disposal
5Under Article 3(1) of that regulation, ‘[wjhere the notifier intends to ship waste for disposal from one Member State to another Member State ... he shall notify the competent authority of destination’.
6Article 4(1), (2) (a) and (c) and (3)(a)(i) and (b)(i) ofthat regulation provides:1. On receipt of the notification, the competent authority of destination shall ... send an acknowledgement to the notifier ...2.(a) The competent authority of destination shall have 30 days following dispatch of the acknowledgement to take its decision authorising the shipment, with or without conditions, or refusing it. It may also request additional information.It shall give its authorisation only in the absence of objections on its part .........(c) The objections and conditions referred to in (a) ... shall be based on paragraph 3....3.(a)(i) In order to implement the principles of proximity, priority for recovery and self-sufficiency at Community and national levels in accordance with Directive 75/442/EEC, Member States may take measures in accordance with the Treaty to prohibit generally or partially or to object systematically to shipments of waste. Such measures shall immediately be notified to the Commission, which will inform the other Member States....(b) The competent authorities of dispatch and destination, while taking into account geographical circumstances or the need for specialised installations for certain types of waste, may raise reasoned objections to planned shipments if they are not in accordance with Directive 75/442/EEC, especially Articles 5 and 7:(i) in order to implement the principle of self-sufficiency at Community and national levels’.
National legislation
7In accordance with Paragraph 1 thereof, the purpose of the Law on the rehabilitation of disused hazardous sites (Altlastensanierungsgesetz) of 7 June 1989 (BGBl. 299/1989; ‘the ALSAG’) is to finance the safeguarding and rehabilitation of disused hazardous sites.
8As set out in Paragraph 2(1), (2), (3), (11), (13) and (14) of the ALSAG:(1) “Disused hazardous sites” are disused disposal premises and disused industrial sites as well as land and ground water systems contaminated by these which — according to the results of a risk assessment — pose significant risk to the health of humans or the environment. Contamination which is caused by emissions into the atmosphere does not come within the scope of application of the Law.(2) “Disused disposal premises” are premises within which waste was disposed of either with or without authorisation.(3) “Disused industrial sites” are premises in which environmentally hazardous substances were handled....(11) “Suspected contaminated sites” are definable areas of disused disposal premises and disused industrial sites which may, in view of their past use, pose significant risk to the health of humans or the environment.(13) “Safeguarding” is the prevention of environmental risks, in particular any discharges of toxic substances from disused hazardous sites which are hazardous for health and for the environment(14) “Rehabilitation” is the elimination of the cause of the risk or the elimination of the environmental contamination.’
9Paragraph 3 of the ALSAG imposes a levy called ‘Altlastenbeitrag’ (disused hazardous site levy). Paragraph 3(1). 1 and 2 and (2).1 provides:(1) The following shall be subject to the Altlastenbeitrag:1. the long-term depositing of waste, including the transfer of waste to a waste disposal site, even if technical site construction or other purposes are involved;2. the filling in or levelling of uneven ground with waste including its incorporation in geological structures, with the exception of filling in or levelling which has a specific construction function in connection with a superior construction operation (for example, road dikes and roadbeds, railway tracks and foundations, filling in excavations or drainage ditches);...(2) The following shall be exempt from liability to pay the levy:1. the depositing, storage and transport of waste which is proven to arise in the course of safeguarding or rehabilitating(a) suspected contaminated sites entered in the register of suspected contaminated sites, or(b) disused hazardous sites entered in the register of disused hazardous sites.’
10Pursuant to Paragraph 4(1) of the ALSAG, it is ‘the operator of a waste disposal site’, in particular, who is liable to the Altlastenbeitrag.
11Paragraph 5 of the ALSAG defines the ‘basis for calculating’ the Altlastenbeitrag as ‘the mass of the waste, corresponding to the gross weight ... which is the weight of the waste, including packaging’.
12The rate of the Altlastenbeitrag, expressed in euros ‘by tonne, rounded upwards’, is set in Paragraph 6 of the ALS AG. That provision lays down a tariff which varies according to the nature of the waste, the date of deposit and the equipment of the waste disposal site.
13Under Paragraph 11 of the ALS AG, the revenue from the Altlastenbeitrag is used for the investigation and rehabilitation of contaminated sites.
14The register of suspected contaminated sites and the register of disused hazardous sites referred to in Paragraph 3(2).1 of the ALS AG are regulated in Paragraph 13 of that law. That provision states:(1) The Landeshauptmann shall inform the Federal Minister for Environment, Youth and Family of suspected contaminated sites. For the purposes of the assessment of disused hazardous sites, the Federal Minister for Environment, Youth and Family shall coordinate the national assessment, appraisal and evaluation of suspected contaminated sites in collaboration with the Federal Minister for Economic Affairs and the Federal Minister for Agriculture and Forestry and shall arrange through the Landeshauptmann, according to existing means (Paragraph 12(2)), additional inspections in so far as they are required for the assessment, appraisal and evaluation of suspected contaminated sites and for the classification of priorities. The data and information gained from the assessment shall be sent to the Umweltbundesamt [Federal Environment Office], analysed by the Umweltbundesamt and entered in a register of suspected contaminated sites (Paragraph 11(2).2).(2) For the purposes of the assessment of disused hazardous sites, the Federal Minister for Environment, Youth and Family shall coordinate all measures for the assessment of the risk potential of the suspected contaminated sites covered. Suspected contaminated sites found to require safeguarding or rehabilitation on the basis of the risk assessment shall be identified as disused hazardous sites in a register of disused hazardous sites (Paragraph 11(2).2) to be kept by the Umweltbundesamt....’
15According to the Verwaltungsgerichtshof (Administrative Court), naturally only areas located in Austria can be entered in the register of suspected contaminated sites and the register of disused hazardous sites since those registers serve to assess disused hazardous sites located in Austria for the purposes of preparation for their safeguarding and rehabilitation. For that reason, only waste which comes from the safeguarding or rehabilitation of disused hazardous sites or suspected contaminated sites in Austria qualifies for the exemption from the Atlastenbeitrag provided for in Paragraph 3(2).1 of the ALSAG.
The main proceedings and the question referred
16Gemeindebetriebe Frohnleiten GmbH, which is wholly owned by the Stadtgemeinde Frohnleiten, operates the municipal waste disposal site at Frohnleiten.
17In the fourth quarter of 2001 and the first quarter of 2002, a number of tonnes of shredded waste from Italy were deposited at that waste disposal site. Their shipment to Austria had been authorised by the Austrian authorities, in accordance with Articles 3 to 5 of Regulation No 259/93.
18The waste arose in the course of the rehabilitation of an area located in the municipality of Rovigo (Italy) and identified as requiring rehabilitation in the Italian plan for the rehabilitation of contaminated sites, drawn up pursuant to Article 22 of Decree-Law No 22 of 5 February 1997 (ordinary supplement to the Gazzetta Ufficiale della Repubblica Italiana (the Official Gazette of the Italian Republic, ‘GURI’) No 38 of 15 February 1997), and the Decree of the Italian Environment Minister of 16 May 1989 (GURI No 121 of 26 May 1989, p. 12).
19Taking the view that the waste was covered by the exemption under Paragraph 3(2).1 of the ALSAG on the ground that it came from a contaminated site, the claimants in the main proceedings applied to the Bezirkshauptmannschart Graz-Umgebung (administrative authorities of the District of Graz and surrounding area; ‘the BH’) for confirmation of the exemption.
20By decision of 11 May 2004, the BH determined that the waste in question was exempt from the Altlastenbeitrag under Paragraph 3(2).1 of the ALSAG. On an appeal by the Austrian federal authority, the Landeshauptmann von Steiermark (head of the government of Styria, ‘the LH’) confirmed the BHs decision by decision of 30 November 2004. Both the BH and the LH found that any distinction between categories of waste arising in the course of lawful measures for the rehabilitation or safeguarding of contaminated sites according to whether it came from Austria or another Member State would be contary to Article 90 EC.
21By decision of 10 January 2005, the Minister annulled the LH's decision and decided that the waste in question should be subject to the Altlastenbeitrag, as it did not come from a site entered in the register of suspected contaminated sites or the register of disused hazardous sites. The Minister considered that the Altlastenbeitrag fell outside the scope of Article 90 EC because it is not a levy on waste as such, but a levy on an operation. The levy is not charged on marketable products the cost of which it increases and which are therefore disadvantaged when sold in Austria, but is a tax on any measure which definitively ends the life cycle of such products.
22The claimants in the main proceedings challenged the Ministers decision before the Verwaltungsgerichtshof. They claim, in essence, that the Altlastenbeitrag falls within the scope of Article 90 EC and that there would be a breach of that provision if the tax were calculated differently depending on whether it is imposed on imported products or on similar domestic products, with the result that imported products were more expensive.
23The Verwaltungsgerichtshof notes that the ALSAG pursues environmental policy objectives, namely safeguarding and rehabilitating disused hazardous sites. The implementation of that policy necessitates prior identification of the disused hazardous sites by means of field inspections. Accordingly, only sites in Austria can be identified as disused hazardous sites within the meaning of the ALSAG. According to the Verwaltungsgerichtshof, it does not follow that the Austrian authorities are required to refrain from giving preferential treatment to the depositing of waste from such sites. It is not apparent from the case-law of the Court that the exemption under Paragraph 3(2).1 of the ALSAG infringes Community law.
24Taking the view, however, that that interpretation is not free from doubt, the Verwaltungsgerichtshof decided to stay the proceedings and to refer the following question to the Court:‘Do Articles 10 EC, 12 EC, 23 EC, 25 EC, 49 EC or 90 EC preclude a national tax provision which makes the deposit of waste at a waste disposal site subject to a tax (Altlastenbeitrag; disused hazardous site levy), but provides for exemption from that tax for the deposit of waste which demonstrably derives from the safeguarding or rehabilitation of contaminated sites (suspected contaminated sites or disused hazardous sites) if the sites (suspected contaminated sites or disused hazardous sites) are entered in official registers provided for by law (Verdachtsflächenkataster; register of suspected contaminated sites, or Altlastenatlas; register of disused hazardous sites), and only sites in Austria may be entered in those registers, with the result that the tax exemption is also possible only in respect of the deposit of waste which originates from suspected contaminated sites or disused hazardous sites located in Austria?’
The question referred for a preliminary ruling
Articles 23 EC, 25 EC and 90 EC
25By the first part of its question, the national court seeks to ascertain whether a national levy such as the Altlastenbeitrag constitutes a charge having equivalent effect to a customs duty on imports within the meaning of Articles 23 EC and 25 EC or internal taxation which is discriminatory and, therefore, contrary to Article 90 EC
26It must first be borne in mind that EC Treaty provisions relating to charges having equivalent effect and those relating to discriminatory internal taxation cannot be applied together, so that under the system of the Treaty the same measure cannot belong to both categories at the same time (see, in particular, Case C-90/94 Haahr Petroleum [1997] ECR I-4085, paragraph 19; Case C-387/01 Weigel [2004] ECR I-4981, paragraph 63, and Joined Cases C-393/04 and C-41/05 Air Liquide Industries Belgium [2006] ECR I-5293, paragraph 50).
27As regards Articles 23 EC and 25 EC, it is settled case-law that any pecuniary charge, however small and whatever its designation and mode of application, which is imposed unilaterally on goods by reason of the fact that they cross a frontier, and which is not a customs duty in the strict sense, constitutes a charge having equivalent effect within the meaning of Articles 23 EC and 25 EC (see, in particular, Haahr Petroleum, paragraph 20; Case C-213/96 Outokumpu [1998] ECR I-1777, paragraph 20; Weigel, paragraph 64, and Air Liquide Industries Belgium, paragraph 51).
28In the light of that definition and as regards the characteristics of the Altlastenbeitrag, it should be noted that all long-term depositing of waste is in principle subject to payment of that levy, whether the waste comes from Austria or another Member State. A levy such as the Altlastenbeitrag is not therefore charged because a border of the Member State which imposed that levy has been crossed.
29Whether such a levy is consistent with Community law cannot therefore be assessed in the light of Articles 23 EC and 25 EC.
30As regards Article 90 EC, that provision, within the system of the Treaty, supplements the provisions on the abolition of customs duties and charges having equivalent effect. Its aim is to ensure free movement of goods between the Member States in normal conditions of competition by the elimination of all forms of protection which may result from the application of internal taxation that discriminates against products from other Member States (see, in particular, Air Liquide Industries Belgium, paragraph 55, and Case C-313/05 Brzeziński [2007] ECR I-513, paragraph 27).
31According to settled case-law, pecuniary charges resulting from a general system of internal taxation applied systematically, in accordance with the same objective criteria, to categories of products irrespective of their origin or destination fall within Article 90 EC (see Air Liquide Industries Belgium, paragraph 56 and the case-law cited).
32In the first place, it should be ascertained whether a levy such as the Altlastenbeitrag constitutes internal taxation within the meaning of Article 90 EC.
33In this respect, the Court finds that that levy, which is manifestly of a fiscal nature, is charged on all long-term depositing of waste at a waste disposal site, whether that waste comes from Austria or another Member State.
34The Austrian Government submits however that the Altlastenbeitrag falls outside the scope of Article 90 EC on the ground that it is not a levy imposed on products within the meaning of that provision. Since waste deposited at waste disposal sites has no pecuniary value, the Altlastenbeitrag is not imposed on goods in trade the cost of which could be increased by that levy and which could be disadvantaged when sold domestically.
35According to the Austrian Government, the Altlastenbeitrag is imposed on a supply of services by the operator of the waste disposal site and depends on the nature of that service. It states in particular that, under Paragraph 6 of the ALSAG, the tax burden is determined not by the nature of the waste being deposited, but by the nature of the disposal installations and by the quality of the management of those installations.
36The Austrian Governments argument that, since it has no market value, waste for disposal is not covered by the concept of ‘products’ within the meaning of Article 90 EC cannot succeed.
37First, in Case C-2/90 Commission v Belgium [1992] ECR I-4431, ‘the Walloon waste judgment’, paragraph 28, the Court held that waste, whether recyclable or not, is to be regarded as ‘goods’ the movement of which, in accordance with Article 30 of the EC Treaty (now, after amendment, Article 28 EC), must in principle not be prevented.
38Second, the Court stated, at paragraphs 25 and 26 of that judgment, that waste for disposal, even if it has no intrinsic commercial value, may none the less give rise to commercial transactions in relation to the disposal or deposit thereof. Internal taxation imposed on that waste is such as to render more difficult or more burdensome those commercial transactions for an operator who seeks to dispose of that waste and, therefore, is liable to constitute a disguised restriction on the free movement of that waste, a restriction that Article 90 EC is specifically intended to preclude in cases of discriminatory treatment of imported waste.
39The Austrian Governments argument that a levy such as the Altlastenbeitrag is not imposed on products but on a supply of services should also be rejected.
40According to settled case-law, Article 90 EC must be interpreted widely so as to cover all taxation procedures which, directly or indirectly, undermine the equal treatment of domestic products and imported products. The prohibition laid down in that article must therefore apply whenever a fiscal charge is likely to discourage imports of goods originating in other Member States to the benefit of domestic production (Case 20/76 Schüttle [1977] ECR 247, paragraph 13; Case 252/86 Bergandi [1988] ECR 1343, paragraph 25, and the case-law cited, and Case C-45/94 Ayuntamiento de Ceuta [1995] ECR I-4385, paragraph 29).
41In Bergandi and Joined Cases 317/86, 48/87, 49/87, 285/87, 363/87 to 367/87, 65/88 and 78/88 to 80/88 Lambert and Others [1989] ECR 787, the Court ruled that Article 95 of the EEC Treaty (which became Article 95 of the EC Treaty, now, after amendment, Article 90 EC) applies to internal taxation which is imposed on the use of imported products where those products are essentially intended for such use and have been imported solely for that purpose.
42The Court finds that a levy such as the Altlastenbeitrag, the imposition of which is triggered by the long-term depositing at a disposal site of waste for disposal, is imposed on the only commercial transaction to which that waste can still be subject, other than those in relation to its disposal, and that, in the case of waste from other Member States which is subject to that levy, such waste is imported into the levying Member State solely for the purpose of that transaction.
43Furthermore, as is apparent from Schöttle (paragraphs 12 to 15) and Haahr Petroleum (paragraphs 38 and 40), a charge which is imposed not on products as such, but on the specific activity of an undertaking in connection with products and which is calculated according, inter alia, to the weight of the products at issue, falls within the scope of Article 90 EC and, in so far as it has an immediate effect on the cost of national and imported products, must be applied in a manner which is not discriminatory to imported products.
44That case-law has been developed in the context of the movement of goods with a market value which are liable to be offered for sale in the importing Member State, in respect of which the effect on cost was the appropriate criterion for the purposes of assessing any restrictions on the free movement of goods.
45By contrast, to the extent that, as recalled at paragraph 42 of this judgment, the only commercial transactions to which waste for disposal may give rise are those relating to the disposal or deposit thereof, the appropriate criterion for the purposes of assessing any restrictions on the free movement of those goods is that of the effect of the levy on the price paid by economic operators to dispose of them.
46In this respect, the Court finds that, first of all, the management of a waste disposal site is clearly an activity related to the waste which is deposited there, next, although the quality of the equipment and management of the disposal site is factored into the calculation of the Altlastenbeitrag, it is apparent from Paragraphs 5 and 6 of the ALSAG that the rate of that levy also depends on the weight and nature of the waste deposited and finally, although that levy is paid by the operator of the waste disposal site, he is able to pass it on in the cost of his service to the operator depositing the waste.
47Consequently, a levy such as the Altlastenbeitrag amounts to internal taxation, for the purposes of Article 90 EC, which is imposed indirectly on waste being deposited.
48In the second place, it is necessary to ascertain whether internal taxation such as the Altlastenbeitrag discriminates in a manner contrary to Article 90 EC.
49According to settled case-law, the first paragraph of Article 90 EC is infringed where the tax charged on the imported product and that charged on the similar domestic product are calculated in a different manner on the basis of different criteria which lead, if only in certain cases, to higher taxation being imposed on the imported product (Case C-152/89 Commission v Luxembourg [1991] ECR I-3141, paragraph 20; Weigel, paragraph 67; and Brzeziński, paragraph 29).
50It follows that a system of taxation is compatible with Article 90 EC only if it is so arranged as to exclude any possibility of imported products being taxed more heavily than domestic products and, therefore, only if it cannot in any event have discriminatory effect {Commission v Luxembourg, paragraphs 21 to 25; Haahr Petroleum, paragraph 34; Case C-375/95 Commission v Greece [1996] ECR I-5981, paragraph 29; Case C-68/96 Grundig Italiana [1998] ECR I-3775, paragraph 12; and Brzeziński, paragraph 40).
51For the purposes of assessing whether or not a system of taxation is discriminatory, it is necessary to take into consideration not only the rate of tax but also the basis of assessment and the detailed rules for levying the various duties (Case 55/79 Commission v Ireland [1980] ECR 481, paragraph 8, and the case-law cited; Case C-327/90 Commission v Greece [1992] ECR I-3033, paragraph 11; and Grundig Italiana, paragraph 13).
52A national provision, such as Paragraph 3(2).1 of the ALSAG, which reserves the benefit of exemption from internal taxation to certain domestic products, to the exclusion of imported products, is liable to lead, in certain cases, to higher taxation being imposed on imported products than on domestic products. Such a provision is therefore in principle contrary to the prohibition on discrimination laid down in Article 90 EC (see, to that effect, Case C-212/96 Chevassus-Marche [1998] ECR I-743, paragraph 26).
53The Austrian Government claims, however, that Article 90 EC does not preclude that levy since the Austrian legislation does not establish any inequality of treatment between similar situations. The purpose of the Altlastenbeitrag is to finance the safeguarding and rehabilitation of disused hazardous sites. The exemption from that levy under Paragraph 3(2).1 of the ALSAG pursues the same objective. Such an objective presupposes prior identification of the contaminated sites by means of field inspections, which can be undertaken only in Austria. There is therefore an objective difference between Austrian sites, which can alone be identified, and sites in other Member States.
54The Austrian Government further states that there is also an objective difference according to whether the rehabilitation of a site and the waste disposal occur in the same Member State or in two different Member States, which rules out any inequality of treatment amounting to discrimination. A Member State is not required to treat facts relating to the territory of another Member State in the same way as similar facts relating to its own territory, provided that it does not discriminate on the basis of the nationality of the economic operators. In the present case, the exemption under Paragraph 3(2).1 of the ALSAG applies on the basis of a criterion, the carrying out of the rehabilitation of a contaminated site in Austria, which is objective and non-discriminatory. That exemption does not infringe Article 90 EC since there is no discrimination in relation to goods from other Member States.
55Those arguments must be rejected.
56First of all, although it is settled case-law that, as it now stands, Community law does not restrict the freedom of each Member State to establish a tax system which differentiates between certain products, even products which are similar within the meaning of the first paragraph of Article 90 EC, on the basis of objective criteria, such differentiation is compatible with Community law, however, only if it pursues objectives which are themselves compatible with the requirements of the Treaty and its secondary legislation, and if the detailed rules are such as to avoid any form of discrimination, direct or indirect, against imports from other Member States or any form of protection of competing domestic products (Outokumpu, paragraph 30, and Joined Cases C-290/05 and C-333/05 Nádasdi and Németh [2006] ECR I-10115, paragraph 51).
57As stated at paragraph 52 of this judgment, a national provision such as Paragraph 3(2).1 of the ALSAG is liable to lead, in certain cases, to higher taxation being imposed on imported products than on domestic products. Thus, even if the objective of rehabilitating domestic sites contaminated by waste is compatible with the requirements of the Treaty and secondary legislation, such a provision cannot itself be compatible with Article 90 EC.
58Next, assuming that the Austrian Governments arguments must be construed as calling into question the similarity between waste imported from other Member States and waste produced in Austria, they must also be rejected.
59First, leaving aside their geographical origin, categories of waste similarly intended for disposal by means of long-term depositing are clearly similar products. In particular, it should be noted that the exemption from the levy under Paragraph 3(2).1 of the ALSAG draws no distinction according to the hazardous nature or other characteristics of the waste deposited.
60Second, the question whether the difference of origin between domestic waste and waste imported from other Member States is sufficient to preclude their similarity for the purposes of the first paragraph of Article 90 EC must be answered in the negative.
61It is true that, at paragraphs 34 and 35 of the Walloon waste judgment, the Court noted the particular nature of waste, arising from the fact that, pursuant to the principle that environmental damage should as a matter of priority be remedied at source, which is consistent with the principles of proximity and self-sufficiency, waste must be disposed of as close as possible to the place where it is produced, in order to limit as far as possible the transport of waste. It concluded, at paragraph 36 of that judgment, that, having regard to the differences between waste produced in different places and to the connection of the waste with its place of production, national rules which treat differently waste produced domestically and that coming from other Member States are not discriminatory.
62However, that finding related only to non-hazardous waste, which did not fall within the scope of Council Directive 84/631/EEC of 6 December 1984 on the supervision and control within the European Community of the transfrontier shipment of hazardous waste (OJ 1984 L 326, p. 31).
63Since the Walloon waste judgment, the Community legislature has adopted Regulation No 259/93, which repealed and replaced Directive 84/631, whilst extending the system set up to all waste, hazardous and non-hazardous, with the exception of certain types of specific waste exhaustively listed in Article 1 of that regulation.
64The Court has held that the conditions and procedures established by Regulation No 259/93 in respect of shipments of waste between Member States were adopted with a view to ensuring the protection of the environment, taking account of objectives falling within the scope of environmental policy such as the principles of proximity, priority for recovery and self-sufficiency at Community and national levels (Case C-187/93 Parliament v Council [1994] ECR I-2857, paragraphs 21 and 22, and Case C-324/99 DaimlerChrysler [2001] ECR I-9897, paragraph 41).
65The Court has also held that Regulation No 259/93 governs in a harmonised manner, at Community level, the question of shipments of waste in order to ensure the protection of the environment (DaimlerChrysler, paragraph 42).
66Article 4(3) of that regulation provides inter alia, in points (a)(i) and (b)(i) respectively, for the possibility for the authorities of the Member State of destination to take measures to prohibit generally or partially or to object systematically to shipments of waste and to raise reasoned objections to planned shipments of waste, and this is in order to implement the principles of proximity and self-sufficiency at Community and national levels.
67It follows that once a Member State has refrained from taking measures to prohibit generally or partially or to object systematically, as provided for in Article 4(3)(a)(i) of Regulation No 259/93, and has not raised any reasoned objections to a shipment of waste, as provided for in Article 4(3)(b)(i), it cannot impose restrictions or limitations on the free movement in its territory of shipped waste on the basis of the principles of proximity and self-sufficiency at Community and national levels (see, to that effect, as regards Directive 84/631, the Walloon waste judgment, paragraphs 20 and 21).
68Such is the case where, as in the main proceedings, the authorities of a Member State authorise, in accordance with Articles 3 to 5 of Regulation No 259/93, the shipment on their territory of waste from another Member State.
69Furthermore, paragraphs 34 to 36 of the Walloon waste judgment did not relate to the examination of a fiscal measure in the light of Article 95 of the EEC Treaty, but formed part of reasoning relating to whether it is possible to justify a national measure which constitutes an obstacle to the free movement of waste for the purposes of Article 30 of the EEC Treaty (which became Article 30 of the EC Treaty, now, after amendment, Article 28 EC) by the imperative requirement of environmental protection (see the Walloon waste judgment, paragraphs 29 to 34).
70Lastly, as regards the material impossibility, pleaded by the Austrian Government, of identifying disused hazardous sites or suspected contaminated sites in other Member States, it must be pointed out that practical difficulties cannot justify the application of internal taxation which discriminates against products from other Member States (Commission v Greece, paragraph 47, and Outokumpu, paragraph 38).
71While it may indeed be extremely difficult for the Austrian authorities to ensure that sites located in other Member States, from which waste imported into Austria comes, satisfy the requirements laid down in the Austrian legislation at issue in the main proceedings in order to be categorised as disused hazardous sites or suspected contaminated sites, that legislation does not even give the importer the opportunity of adducing that proof in order to qualify for the exemption applicable to waste from disused hazardous sites or suspected contaminated sites in Austria (see, to that effect, Outokumpu, paragraph 39).
72Moreover, even if, in principle, Article 90 EC does not require Member States to abolish differences which are objectively justified and which national legislation establishes between internal taxes on domestic products, it is otherwise where such abolition is the only way of avoiding direct or indirect discrimination against the imported products (Case 21/79 Commission v Italy [1980] ECR 1, paragraph 16, and Outokumpu, paragraph 40).
73In the light of all the foregoing considerations, the answer to the first part of the question referred for a preliminary ruling must be that the first paragraph of Article 90 EC precludes a national tax provision such as Paragraph 3(2).1 of the ALSAG which exempts from the levy imposed on the long-term depositing of waste at waste disposal sites in the Member State concerned deposits of waste derived from the rehabilitation or safeguarding of disused hazardous sites or suspected contaminated sites located in that Member State alone, but excludes exemption of deposits of waste derived from the rehabilitation or safeguarding of sites located in other Member States.
The interpretation of Articles 10 EC, 12 EC and 49 EC
74In the light of the Courts answer to the first part of the question referred for a preliminary ruling, there is no need to interpret Articles 10 EC, 12 EC and 49 EC.
Costs
75Since these proceedings are, for the parties to the main proceedings, a step in the action pending before the national court, the decision on costs is a matter for that court Costs incurred in submitting observations to the Court, other than the costs of those parties, are not recoverable.
Operative part
On those grounds, the Court (First Chamber) hereby rules: The first paragraph of Article 90 EC precludes a national tax provision such as Paragraph 3(2). 1 of the Law on the rehabilitation of disused hazardous sites (Altlastensanierungsgesetz) of 7 June 1989 which exempts from the levy imposed on the long-term depositing of waste at waste disposal sites in the Member State concerned deposits of waste derived from the rehabilitation or safeguarding of disused hazardous sites or suspected contaminated sites located in that Member State alone, but excludes exemption of deposits of waste derived from the rehabilitation or safeguarding of sites located in other Member States,
