§ 26. Mr. DuffyTo ask the Secretary of State for the Environment what estimate he has made of the number of sites in England and Wales that may be emitting methane gas in quantities likely to present hazards to personal health and the local environment.
§ Mr. Heathcoat-AmoryReliable and complete information on these sites is not held centrally. This is the responsibility of waste disposal authorities which have co-operated in studies made by Her Majesty's inspectorate of pollution. I expect to receive a report on this shortly.
