What are the NSW Excavated Natural Material guidelines?

NSW Excavated Natural Material standards and guidelines are passed by the Environmental Protection Authority (EPA), and it provides the requirements that should be observed by suppliers of excavated natural materials regarding uses such as application in earthworks or engineering fills. Under regulations, excavated natural material refers to naturally occurring soil and rocks excavated from the ground and has at least 98% of natural material by weight. The standards and regulations apply to all suppliers of excavated raw materials. 

Chemical and other material requirements forbid the supply of materials exceeding the defined absolute maximum concentration or the maximum average concentration. Sampling requirements require suppliers to prepare sampling plans and perform sampling and testing of the materials. It also includes characterization sampling of chemicals, segregation and exclusion of hotspots, the subdivision of sites exceeding 50,000m2, and proper storage of excavated natural material. Chemicals covered include mercury, copper, cadmium, zinc, arsenic, lead, toluene, and ethyl-benzene. 

Consequently, the standards require testing of excavated natural materials conducted by analytical laboratories approved by the National Association of Testing Authorities (NATA). It must also utilize test methods specified in the standards and guidelines, for instance, the USEPA SW-846 method. Additionally, the guidelines require that suppliers provide notifications to those they intend to supply. Suppliers are also required to comply with record-keeping and reporting requirements. Information passed includes a written statement of compliance and copies of excavated natural material exemption and order. 

The NSW Excavated Natural Materials standards and guidelines aim to reduce the risk of potential harm to human health, the environment, and agriculture. The suppliers must ensure that the application of these guidelines complies with other legislative requirements; hence they complement one another.
