814.680 order on remediation of polluted sites (contaminated sites, CSO Ordinance) of August 26, 1998 (Status January 1, 2016) the Swiss federal Council, view the art. 32 c, al. 1, second sentence, and 39, al. 1, of the law of 7 October 1983 on the protection of the environment (LPE), stop: Section 1 provisions general art. 1 purpose and object this order is intended to ensure that contaminated sites will be remediated if they cause attacks troublesome or harmful to the environment, or if there is a real danger that such violations appear.
It stipulates the details of the treatment of the sites according to the following steps: a. identification of the polluted sites and establishment of a land register; b. determination of surveillance and sanitation needs; c. evaluation of the goals and the urgency of sanitation; d. investigative measures fixing, monitoring and remediation.

Art. 2 definitions means polluted sites polluted by waste sites of a limited scope. These sites include: a. the final storage sites: landfills, decommissioned or even exploited and any other place of final storage of waste; excluded are sites in which are exclusively of the excavated material deposited and no contaminated cuttings; b. areas of farms: sites polluted by plants or abandoned farms or even exploited in which have used substances dangerous for the environment; c. the accident scene: sites polluted as a result of extraordinary events, faults operating there understood.

Polluted sites require sanitation if they generate attacks harmful or troublesome or if there is a real danger that such violations appear.
Contaminated sites are contaminated sites that require remediation.

1999 2251 Art. RO 3 creation and transformation of buildings and facilities polluted sites cannot be changed by the creation or transformation of buildings and facilities that: a. If they don't require sanitation and if the project does not need for remediation. forgotten the source. If the project does not significantly hinder the subsequent remediation of the sites or these, insofar as they are modified by the project are reorganized at the same time.

Art. 4 General requirements for measures to take the investigation, monitoring and remediation measures taken under this order must correspond to the State of the art and be recorded by people who are required to take.

Section 2 Cadastre of polluted sites art. 5 establishment of cadastre authority lists them sites polluted by stripping the available data such as maps, inventories, and information. She may request information to the holders of the sites or third parties.
She communicates the holder data is planning to register in the land register and given the opportunity to comment and to provide clarification. At the request of the holder, it makes a decision in finding.
She registered at the land registry sites for which pollution is established or very likely according to the al. 1 and 2. Registration must fill in as possible on: a. location; (b) the type and the amount of waste on the site; c. the period of storage of the waste, the operating period or the date of the accident; d. investigations and measures of protection of the environment already carried out; e. already observed violations; f. the areas of the environment threatened; g. the events such as the incineration of waste landslides, floods, fires or major accident.

On the basis of the information in the cadastre, in particular of those concerning the types of waste deposited on the site and their amount, the authority ranks sites polluted into two categories: a. sites for which expected to no interference harmful or burdensome, etb. sites to conduct an investigation to determine if they require supervision or sanitation.

The authority shall establish a list of priorities for the execution of the investigations. In so doing, it takes into account, according to the information in the cadastre, the type and quantity of waste deposited on the polluted site of the possibility of dissemination of substances as well as the importance of the areas of the environment involved.

Art. 6 management of cadastre authority complete the cadastre by indications on: a. the need to clean up or monitor the site; b. the objectives and the urgency of sanitation; (c) the measures it has taken or prescribed to protect the environment.

It removes a site polluted land registry registration: a. If the investigations show that it is not polluted by hazardous substances to the environment, forgotten the source. If substances dangerous for the environment have been eliminated.

Art. 6aCoordination with master plans and assignment plans the authority takes account of the cadastre when establishing master plans and assignment plans.

Introduced by section 9 of Schedule 6 to the O of 4 Dec. 2015 on waste, in force since Jan. 1. 2016 (2015 5699 RO).

Section 3 monitoring and Art. sanitation needs 7 preliminary investigation on the basis of the list of priorities, the authority requests that a prior investigation of the sites requiring an investigation be carried out in a reasonable; This includes generally a historical investigation and technical investigation. These allow to identify the data needed to assess the needs of monitoring and sanitation (art. 8) and to assess from the point of view of the endangering of the environment (estimate of risk).
Historical investigation to identify the likely causes of the pollution of the site, in particular: a. the events and changes in the activities on the site in the space and the time; b. the process in which substances dangerous for the environment have been used.

A specifications stating the purpose and scope of the technical investigation as well as the methods used is established on the basis of historical investigation. It is submitted to the authority for an opinion.
The technical investigation is used to identify the type and quantity of substances present on the site, their possibility of dissemination as well as the importance of the areas of the environment involved.

Art. 8 assessment of the needs of monitoring and sanitation authority examines, on the basis of the preliminary investigation, if the polluted site requires a monitoring or a reorganization under arts. 9 to 12. In doing so, it takes account of violations caused by other polluted sites or by third parties.
She mentions in the cadastre polluted site: a. requires supervision; (b) requires a remediation (contaminated site); c. requires no monitoring or remediation.

Art. 9 protection of the groundwater polluted site requires supervision from the point of view of the protection of groundwater, subject to para. 1: a.

If a surveillance of several years reveals that, due to the characteristics of the site and the development of concentrations of pollutants over time, the site very probably will not require remediation according to para. 2, monitoring of the site is no longer necessary.
A contaminated site requires remediation from the point of view of the protection of groundwater: a. If, in the catchments of groundwater intended for public use, there is the presence of substances from the site and likely to pollute water; (b) If, in groundwater located in the sector to the protection of waters, the concentration of the substances flowing site exceeds , downstream near the site, half of the value of concentration mentioned in annex 1; c. If, in groundwater located out of the sector to the protection of the waters, the concentration of the substances flowing site exceeds, downstream near the site, the double of the value of the concentration referred to in annex 1; Oud. so, according to para. 1, let. a, the site requires monitoring and a concrete danger of pollution of groundwater due to a retention or insufficient degradation of substances from the site.

Art. 28 entry into force this order comes into force on October 1, 1998.

Annex 1 (arts. 9 and 10) values of concentration for assessment of violations brought to the waters by the polluted sites to assess water violations by polluted sites, it will be based on concentration values given in the table below. If no concentration value has been determined for certain substances that can pollute water and on a site, the authority sets the values required on a case by case basis in agreement with the FOEN, according to the requirements of the law on the protection of the waters.
If the evaluation refers to the leachate of the materials present on the site, sampling, preparation and analysis of leachate will be subject to the following requirements: a. you will choose the number of samples and the place where they will be taken so that the samples are representative of the pollution of the site; b. the leachate will be prepared by means of a test on column leaching. As a leaching agent, use water deionized and désoxygénée. In principle, it will have to cross the column up and down at a given flow rate. The leachate must be generally centrifuged or filtered prior to analysis by a microfilter; c. the leachate must be analyzed from the point of view of the substances should be expected to find on the site on the basis of historical investigation. If we analyse only total parameters, valid evaluation criterion will always be the value of the lowest concentration of various substances.

It is possible to take samples of water percolation on sites with pollution particularly heterogeneous (e.g. final storage sites), these samples may be considered as the leachate.
To assess the damage caused by volatile substances, considered water percolation as leachate; If it is not possible to take samples of the percolation water, the concentration of the latter will be calculated from the measurements of the concentration of the interstitial air.
It is possible to waive an analysis of leachate according to para. 2 when you can see, on the basis of other information such as the composition or the origin of the materials present on the site, the total parameters, ecotoxicological analyses or math from global makers deductions, whether or not the concentration value has been exceeded.
The Agency issues directives on the taking of samples, preparation of leachate and their analysis as well as on the assessment of damage by volatile substances.

Marked with a * in the State on 1 January 2016 table annex 2 (art. 11) concentration values for the evaluation of interstitial sites air polluted to assess the interstitial air of polluted sites, it will be based on the values of concentration of the table below. If the site gives off emissions for which no value of concentration has been determined, such as odors or dust, it requires a remediation when emissions may become excessive Immissions within the meaning of the Ordinance of December 16, 1985 on the protection of the air.
Sampling and analysis of interstitial air are subject to the following requirements: a. sampling will be done with probes for gas from the ground, a representative number of places of the pollution of the site. Ensure not to aspire to air during the collection of samples; (b) simply to analyse, in the interstitial air, substances whose presence on the site is likely based on historical investigation. If we analyse only total parameters, valid evaluation criterion will always be the value of the lowest concentration of various substances.

It is possible to waive the interstitial air sampling if there is other proof that the concentration in the interstitial air values cannot be exceeded, especially if you know exactly the composition and origin of the materials present on the site.
The office issues guidance on sampling and analysis of interstitial air.
