It is crucial that your project import only clean fill. Contractor’s must provide you with a statement that the soil is not contaminated and if necessary laboratory data. In some cases, particularly if large amounts of soil are being imported, or if the origin of the soil is not well documented, the University requires that the soil importer provide a description of the soil source, sampling plan, and laboratory analytical results. The project manager should develop a soil import plan with EH&S prior to the project commencing.
