Screening Soil clear as mud
A new method to check if land is not contaminated is being drawn up so savings worth millions to the development sector can be realised. Uncertainty reigns over whether the project to develop so called category four screening levels (C4SLs) will mesh with planning policy and if it does not then hoped-for savings will be unattainable.
Others say the project lacks transparency, is taking decisions that ought to be taken by government and is failing to adequately explain its approach to others. The C4SLs are designed to replace Soil Guideline Values (SGVs) used to screen land under the Part 2A contaminated land regime. They are expected to be derived from the same model but with a variety of modifications on toxicology and exposure to make the C4SLs less conservative.
