§ Mrs. Anne Campbell
To ask the Secretary of State for the Environment if it is his Department's policy to permit the permanent use of secondary liquid fuels. 
§ Mr. Clappison
Each application for the burning of secondary liquid fuels will be determined on its own merit and in accordance with the requirements of the Environmental Protection Act 1990. If the operator of the plant has demonstrated, by trials, that there is no net adverse effect on the environment, authorisation with strict conditions under the Act is likely to be granted.
