Soil Stockpile Reuse Investigation, Sydney NSW

stockpile reuse

iEnvi assessed a 1,800 m3 soil stockpile for an inner-west Sydney council to determine suitability for reuse. Targeted test pits and laboratory analysis showed the material generally met the Excavated Natural Material Order 2014 criteria but required processing and a Specific Resource Recovery Order/Exemption from the NSW EPA before reuse as bunding engineering fill.
