Application of dispersion models in the environmental assessment process in the United Kingdom
The UK planning process has traditionally been separated from the licensing process as far as industry is concerned. Implementation of the Environmental Assessment Directive (85/337/EEC) has therefore been the responsibility of planners, not pollution regulators. This is one of the reasons why there are no formalised procedures for using dispersion models in the environmental assessment process. In the absence of-centralised guidance, practitioners of environmental assessment have largely turned to the models made available by the United States Environmental Protection Agency (US EPA). These models have proved to be very useful and able to provide a service to developers at an attractive price. It is likely that they will continue to be used in environmental assessment for the time being, unless compelling new economic or regulatory factors emerge.
