VENM and ENM Waste Classification
VENM and ENM are more than simple waste classification, these are classifications made to determine if soil is suitable for reuse. According to the EPA all soil stockpiles for the purpose of re-use as fill must be classified as either VENM or ENM in order to me transported and used as fill.
What each of these classifications mean
VENM (Virgin Excavated Natural Material) is soil that is undisturbed, and found to be uncontaminated and a chemically stable soil unlike acid sulfate soil. Disturbances of this material or contamination from previous use, does not allow for the classification of VENM. Should soil show signs of disturbance such as mixing or contamination of manufactured chemicals or residues present, then there is the option of ENM (Excavated Natural Material) classification. ENM exemption allows for the reuse of disturbed or minor contaminated material. ENM classification requires that the material undergo extensive chemical, visual, and physical assessment of contaminated within the soil. After assessing the soil and comparing results as to that of the required maximum level of pollutants set out by the EPA, a judgement of ENM or Waste classification can be made.
