HC Deb 14 May 1925 vol 183 cc2050-1W
Captain P. MACDONALD

asked the First Lord of the Admiralty what action, if any, has been taken by his Department to provide means for preventing the pollution of our coastal waters and ports with oily ballast water discharged from Admiralty vessels; and whether his Department has conducted any trials with oil separators. and with what results?

Mr. DAVI DSON

The present strict orders on the subject of discharge of oily ballast water should prevent any serious pollution of coastal waters and ports by Admiralty vessels. The Admiralty is watching closely the development of oil separators. Various types have been examined, and many demonstrations have been witnessed. Although considerable advance has been made in the efficiency of oil separators, the standard necessary to justify adoption by the Admiralty has not, as yet, been attained.
