520			_aCurrent government policy favours greater use of marine sources of sand and gravel rather than onshore reserves, but according to a report by consultants Sea Sediments Survey and Consultancy and C & C Mineral Planning Services for the DOE , reliance on continuing supplies of sea-dredged aggregates may be misplaced, as since 1965 "the total quantity dredged each year has...greatly exceeded the additional quantities licensed by the Crown Estates Commissioners resulting in a serious depletion of offshore licensed reserves." Reserves in the Northern area could be exhausted by 1993. The consultants recommendations range from better data collection to more forward comprehensive planning for reserve depletion.
