The property investors attitude to land: "Buy now, they stopped making it long ago" is fairly sound, although not strictly true on a geological timescale. There is powerful evidence that the global stock of useful land is being depleted by erosion and degraded through misuse of resources. Further, there is persuasive scientific evidence that suggests climate change will cause inundation of low-lying land by rising sea levels. These are good reasons for recycling land as well as bottles and tin cans and they are reflected in government planning policy promoting the redevelopment of "brownfield" sites.
The scope for reclamation in Britain is as large as the legacy of several centuries of neglect - thousands of hectares of derelict, contaminated or otherwise unusable sites previously used for gasworks, chemical factories etc. In many cases, complete removal of pollutants is not possible and remediation is a set of procedures to "make the harm or potential harm caused by such land tolerable", rather than a cure.
Summary of legal controls on contaminated land
A regulatory system to deal with the problems associated with contaminated land was brought into force as Section 57 of the |Environment Act 1995. Contaminated land is defined as land so polluted by substances in or under it that it could cause significant harm or could cause pollution of controlled waters.
This requires identification and remediation of land where contamination is causing unacceptable risks to human health or the wider environment. It deals with sites of concern which would not otherwise come under planning and development, or pollution control, legislation.
The regime is based upon a 'polluter pays' principle: where possible, those responsible for the contamination should meet the costs of remediation in full. It also encompasses a 'suitable for use' approach: the land should be remediated to a level suitable for its current use, designated use (eg under planning permission), or intended use, rather than for any future use. Development of remedial actions are on a 'risk-based approach'.
Legal controls on contaminated land are enforced by local authorities in most cases (and by the Environment Agency for any land designated a special site). There is a duty to inspect and identify contaminated land (defined in section.78); to inform owners, occupiers and others potentially affected; a duty, in some circumstances, to serve Remediation Notices on those responsible, specifying what needs to be done. Rules apportion costs and describe what happens where the person who caused the contamination cannot be found. There are fines for not complying with a notice to remediate, which increase for each day if the offence continues after conviction. In some circumstances the Environment Agency can move in immediately, take the remedial action necessary and recover costs from the offender. Where there is imminent danger of a need to prevent serious water pollution, the authorities may do the remedial work and charge the owners, or put a Charge on the premises.
These pending controls on contaminated land are complex - the above is only an outline of the new rules - and have wide implications, as it is estimated that 0.2 per cent of all land in England is potentially contaminated. The EU is considering a Directive on civil liability for damage caused by waste (which could cause owners of contaminated sites some headaches!) Existing contamination is a material consideration in planning applications and full Environmental Assessments are needed for certain proposals which might result in future contamination of land.
The Interdepartmental Committee on the Redevelopment of Contaminated Land published a series of guidance notes on ways to deal with problem sites such as old sewage works and scrapyards. These specify trigger concentrations for pollutants which operate as a first step to determine clean-up criteria. A range of grants is currently available for the reclamation of contaminated land.
