Background

The landmark Christy Factory at Hyde was a complex of former textiles mills and dyeworks covering 3.3 ha. The continuing operation of part of the site mill had to be accommodated by the contractor. The reservoirs contained deep silts that were potentially hazardous. Various options for the stabilisation of this material were considered, and Smith Grant helped secure a Contaminated Land tax exemption for the waste. Following a detailed chemical analysis of the waste, which appeared to contain hazardous levels of oils, Smith Grant was able to demonstrate that the sludges actually contained high levels of coal dust and soot, and were non-hazardous for landfill disposal, at a considerable saving. Smith Grant LLP has successfully re-classified many organic wastes as non-hazardous which had previously been identified as hazardous under the Landfill Regulations and Hazardous Waste Directive.
