I have been asked to reply.
Information on what land is used for after remediation is not collected centrally by my Department. The Environment Agency’s 2002 State of Contaminated Land Report, prepared under Part IIA of the Environmental Protection Act 1990, sets out available data on the identification and response to contaminated land dealt with under the Contaminated Land Regime (Part 2A). A further report is expected to be produced later this year, but will not include information on land cleaned up under the planning regime for future use.
