Waste Disposal Sites (Warwickshire) Mr. Litterick asked the Secretary of State for the Environment (1) what is the quantity and nature of the notifiable waste substances dumped on each of the waste sites in Warwickshire during the last 12 months;(2) if he will list in the Official Report the number, location and ownership of toxic waste dumps in Warwickshire. Mr. Denis Howell This information is not available in my Department, as the maintenance of records for individual sites is a matter for the appropriate waste disposal authorities, who have to be notified of the deposit of hazardous waste under the Deposit of Poisonous Waste Act 1972.
