§ Mr. Ron Daviesasked the Secretary of State for the Environment, pursuant to his reply of 23 May, Official Report, column 503, when he expects the review of the method of calculation of sulphur emissions from oil refineries to be completed; and what plans there are to publish it.
§ Mr. WaldegraveI expect the method of calculation to be reviewed in time for any revised factor to be used in calculation of sulphur dioxide emissions from oil refineries during 1984. This figure will be published in the 1986 edition of my Department's Digest of Environmental Protection and Water Statistics. That publication will, as usual, carry an explanation of the method of calculation used.
