Certain types of contaminated land (as described in Regulation 2 of the Contaminated Land (England) Regulations 2006 are required to be designated as special sites. The effect of this is that the Environment Agency becomes the enforcing authority (rather than the Local Authority) and assumes responsibility for requiring remediation to be carried out under section 78E of Part 2A of the Environmental Protection Act 1990 (Part 2A). This dataset is a list of all sites which have been designated as special sites by Local Authorities under section 78C of Part 2A up to 31 March 2019. Some of these sites are no longer special sites as the designation has been terminated. Details include site name, address, date of designation, special site status/category, site area, number of designations and date of any terminations.
