HC Deb 23 July 1987 vol 120 c370W
Ms. Ruddock

asked the Secretary of State for Energy what commercial restrictions cover the disclosure of information on coal waste from power stations.

Mr. Michael Spicer

Coal ash from power stations is widely used in the construction industry and its availability widely publicised. The sale of such waste is a matter for the Central Electricity Generating Board which advises me that only the pricing terms of sales contracts are normally kept confidential.
