HC Deb 09 February 1990 vol 166 c810W
Dr. Kim Howells

To ask the Secretary of State for Wales what is the estimated average cost, per site, of remedial work required to safeguard landfill sites in Wales, including the costs associated with the investigation of geology and hydrogeology necessary as a precursor to such remedial work.

Mr. Grist

The estimation of costs is a matter for the operator of the site. As an approximate indicator Her Majesty's inspectorate of pollution has adopted an average sum of £250,000 when assessing the likely resource implications of landfill gas control.
