§ Dr. Reid
In the case of returned sites, under the terms of the confidential UK/US bilateral cost sharing arrangement, responsibility lies with the Ministry of Defence for rectifying any contamination caused by defence activities which may subsequently be discovered. United States Visiting Forces are expected to observe and abide by environmental protection standards at least equal to UK legislative requirements. If environmental pollution were discovered at a base made available to the United States Visiting Forces, they would normally be responsible for ensuring that the appropriate remedial action was carried out. The timescales for the removal of polluted matter would have to be set on a case by case basis.
