    Section 1 General Provisions

    Art. 1 Purpose and scope

    1 The purpose of this Ordinance is to protect the public and the environment against serious harm or damage resulting from major accidents.

    2 It applies to:

    a.4
    establishments where the threshold quantities for substances, preparations or special wastes specified in Annex 1.1 are exceeded;
    b.5
    establishments where an activity involving genetically modified or pathogenic organisms or alien microorganisms subject to compulsory containment is carried out which is to be assigned to Class 3 or Class 4 in accordance with the Containment Ordinance of 9 May 20126;
    c.7
    railway installations in accordance with Annex 1.2a;
    d.
    transit roads, as defined in the Ordinance of 6 June 19838 on Transit Roads, where dangerous goods are transported or transhipped in accordance with the Ordinance of 17 April 19859 on the Carriage of Dangerous Goods by Road (SDR) or the relevant international agreements;
    e.
    the Rhine, where dangerous goods are transported or transhipped in accordance with the Ordinance of 29 April 197010 on the Carriage of Dangerous Goods on the Rhine (ADNR);
    f.11
    pipeline installations as defined in the Pipelines Ordinance of 26 June 201912 which meet the criteria specified in Annex 1.3.

    2bis The enforcement authority may exempt establishments under paragraph 2 letter b from the scope of this Ordinance that:

    a.
    only carry out Class 3 activities with organisms in accordance with Annex 1.4 which, due to their properties, cannot spread uncontrollably among the public and in the environment; and
    b.
    due to their hazard potential, cannot seriously harm the public or the environment.13

    3 In individual cases, the enforcement authority may make the following establishments, transport routes or pipeline installations subject to this Ordinance if, on account of their hazard potential, they could cause serious harm to the public or damage to the environment:14

    a.15
    establishments handling substances, preparations or special wastes;
    b.16
    establishments where an activity involving genetically modified or pathogenic organisms or alien microorganisms subject to compulsory containment is carried out which is to be assigned to Class 2 in accordance with the Containment Ordinance, in consultation with the Swiss Expert Committee for Biosafety;
    c.
    transport routes outside establishments, where dangerous goods are transported or transhipped in accordance with paragraph 2;
    d.17
    pipeline installations as defined in the Pipelines Ordinance which do not meet the criteria specified in Annex 1.3.18

    4 This Ordinance does not apply to installations and forms of transport which are subject to legislation on nuclear energy and radiological protection, insofar as the associated radiation could cause harm to the public or damage to the environment.19

    5 The provisions of Article 10 EPA are directly applicable to establishments or transport routes which, in the case of exceptional events, could cause serious harm to the public or damage to the environment not arising from substances, preparations, special wastes or dangerous goods, or from genetically modified or pathogenic organisms or alien organisms subject to compulsory containment.20

    2 When evaluating the acceptability of the risk, it shall take account of local risk factors and pay particular attention to the fact that the likelihood of occurrence of a major accident must be all the lower:

    a.40
    the more the need to protect the public or the environment against serious harm or damage arising from major accidents outweighs private and public interests in the operation of an establishment, a transport route or a pipeline installation;
    b.
    the greater the extent of the possible harm to the public or damage to the environment.

    2 If the person responsible has prepared a risk report and the circumstances change significantly thereafter or relevant new findings become available, they must:

    a.
    amend the risk report and resubmit it to the enforcement authority;
    b.
    amend the summary report instead of the risk report and resubmit it to the enforcement authority if:
    1.
    serious harm to the public or to the environment from major accidents need no longer be expected,
    2.
    in the case of transport routes and pipeline installations, the probability of a major accident causing serious harm is sufficiently low.

    2 Determination of threshold quantities

    21 Substances or preparations

    1 For substances or preparations listed in the table under number 3, the threshold quantities specified therein apply.

    2 For other substances or preparations, the person responsible shall determine the threshold quantity using the criteria specified in number 4 in accordance with Annex I of Regulation (EC) No 1272/200867 and the criteria specified in number 5 for highly active substances and preparations. The lowest threshold quantity determined in this way is decisive.

    3 The person responsible need not determine the threshold quantity for a criterion or area if he can argue convincingly that the costs of acquiring the data would be disproportionate.

    67 Regulation (EC) No 1272/2008 of 16 Dec. 2008 of the European Parliament and of the Council on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No 1907/2006, OJ L 353 of 31.12.2008, S. 1; last amended by Regulation (EU) No 2016/1179, OJ. L 195 of 20.7.2016, p. 11.

    22 Special wastes

    The Federal Department of the Environment, Transport, Energy and Communications (DETEC) shall specify the threshold quantities for special wastes designated as such in the waste list issued in accordance with Article 2 of the Ordinance of 22 June 200568 on Movements of Waste. In doing so, it shall take account of their:

    a.
    health risks;
    b.
    physical risks;
    c.
    environmental risks;
    d.

    The listed criteria apply, and the order of the criteria (letters) denotes their priority, i.e. if there is a value under criteria a, criteria b and c are no longer relevant.
    If a person responsible for a substance/preparation that meets one of the criteria concludes based on their self-assessment that harm to the public in the event of exposure on one occasion may be excluded or that the more serious effect of the substance/ preparation is not relevant to major accidents, the substance/ preparation is not deemed to be an HAS in terms of the Major Accidents Ordinance. In order to assess whether an effect is relevant to major accidents, the definition of «Temporary Emergency Exposure Limits (TEEL-2)» applies. The Major Accidents Ordinance does not apply to establishments that handle HAS only in the form of finished products that are intended for their own use or for supply to professional or commercial users or the general public.
