Thanks to everyone who has responded to this. It appears the way forward may
be to develop a questionnaire which can be sent out to developers planning
on agricultural land. Many of those of you who responded used this method to
determine more specific previous use. Obviously there is the possibility a
developer will just tick 'No' for every question, so a site visit afterwards
may be a good idea. If the questionnaire or site visit lead to a suspicion
of risk then a more detailed desk survey will likely be insisted on.
Thanks again,
Neil
