Guidelines on remediation of contaminated sites 1. IntroductionThese guidelines serve to update, extend and supplement the General Sector Guidelines from 1992 /22/. The three sector-specific guidelines for contaminated tar/asphalt sites /25/, contaminated wood-impregnating sites /23/, and contaminated tannery sites /24/ have also been reworked and are included as Appendices 3.3-3.5 of these guidelines. These guidelines are intended to function as a technical instruction on how to deal with a contaminated site, from the investigation phase to the remediation phase. These Guidelines for Remediation of Contaminated Sites are among a series of guidelines which have been submitted to hearing. The others are: Guidelines for the Mapping of Contamination and Its Sources, Guidelines for Sampling and Analysis of Soil, Guidelines for the Instruction of Inhabitants in Mildly Contaminated Areas, and Guidelines for Remediation of Sites Contaminated with Oil and Petrol. The latter is Appendix 3.6 in the present guidelines. The directions given in these guidelines are not binding, but should be seen as the foundation on which the authorities, companies and consultants can base a more equal treatment of cases concerning contamination. However, the authorities should always take the directions given in the guidelines as their point of departure when dealing with cases concerning contamination. The directions given in these guidelines should always be adapted so as to meet the requirements of the existing legislation. In relation to the current legislation, this means that the guidelines cannot be applied directly to the restoration principle of the Environmental Protection Act or to the de-listing situations in the Contaminated Sites Act. This is because a complete removal of contaminated soil from the site is not always necessary in situations where land use and management of the contaminated soil is regulated administratively.
