These Regulations make provision in respect of Scotland for certain aspects of a new scheme under Part IIA of the Environmental Protection Act 1990 for the remediation of contaminated land including land where controlled waters (including those used for the supply of drinking water for human consumption) are being affected by the land. Land shall be designated in accordance with these Regulations as a special site and the Scottish Environment Protection Agency (SEPA) shall be the authority responsible for enforcing the scheme in respect of such sites. The Regulations provide for remediation notices and their follow-up and other environmental controls where authority is precluded from serving a remediation notice.
