To ask the Scottish Executive whether it has received any representations from the British Aggregates Association as to the impact of the proposed Aggregates Levy on their membership in Scotland; whether any such representations drew its attention to the Association's estimate that the cost per tonne of aggregates is around #10 in the South of England compared with around #4 in Scotland; whether it has made any representations to Her Majesty's Government regarding the impact on employment in the aggregates industry in Scotland of introducing the Levy at a fixed rate per tonne of #1.60, and in particular whether it has suggested any amendments to the proposed Levy to lessen its potential impact in Scotland.
