Waste Management: Brofiscin Quarry

Volume 692: debated on Thursday 24 May 2007

asked Her Majesty's Government:

Further to the Written Answer by Lord Rooker on 16 April (WA 31), what was their source for stating that the original depth of the Brofiscin Quarry would have been approximately six metres below current surface levels; and [HL3348]

Further to the Written Answer by Lord Rooker on 16 April (WA 31), by what route access was given to the vehicles carrying toxic waste materials into Brofiscin Quarry between 1965 and 1972; and [HL3349]

Further to the Written Answer by Lord Rooker on 16 April (WA 31), what was their source for stating that the Brofiscin Quarry contains some 72,000 cubic metres of waste material; and what is the approximate tonnage of this volume of waste. [HL3350]

Information relating to the original depth of Brofiscin Quarry was provided by the Environment Agency (EA). We understand that boreholes drilled through the waste mass have encountered solid limestone at approximately 6 metres below the current surface level of the quarry floor.

We have been advised that the exact route taken by haulage vehicles carrying waste material to the quarry was not documented.

The EA also provided information relating to the tonnage of waste at Brofiscin Quarry. We understand that they have made no estimates of the tonnage that this would represent, and that this has not been an objective of inspections to date. The tonnage would depend on the density of the material.
