Virgin Excavated Natural Material (VENM)
Summary
Virgin Excavated Natural Material (VENM) refers to naturally occurring soil, rock or sediment that has been excavated from a site and has not been impacted by human activity or contamination. VENM is considered the lowest-risk category of excavated material and may be reused or disposed of, subject to meeting regulatory criteria.
Correct identification and classification of VENM is important to ensure lawful reuse and avoid the unnecessary disposal of clean material.
Definition
Virgin Excavated Natural Material is natural material, such as soil, clay, sand, gravel or rock, that has been excavated from the ground and has not been mixed with waste or affected by contamination.
VENM excludes material that has been reworked, mixed with fill or impacted by past land use activities.
Why VENM Matters
From a regulatory perspective, VENM classification determines whether excavated material can be reused without being classified as waste.
Incorrectly classifying impacted or fill material as VENM can result in regulatory non-compliance and environmental harm. Conversely, failing to identify material as VENM can lead to unnecessary disposal costs and inefficient project outcomes.
For development and earthworks projects, VENM classification influences excavation planning, material reuse strategies and overall project cost. Early and defensible classification reduces uncertainty and supports efficient construction.
When VENM Assessment Is Typically Required
Assessment of VENM is commonly required where:
Excavation or bulk earthworks are proposed
Soil or rock is intended to be reused on site or transferred off site
Development consent conditions require confirmation of material status
Contaminated land risk needs to be ruled out
Waste classification is required to determine lawful management
VENM assessment is often undertaken alongside soil classification and contaminated land assessment.
Typical VENM Assessment Considerations
VENM assessment commonly considers:
Historical land use and evidence of disturbance
Visual and olfactory observations
Soil stratigraphy and consistency
Laboratory testing where required to confirm absence of contamination
Applicable regulatory definitions and guidance
Where uncertainty exists, targeted sampling may be required to support VENM classification.
Legislative and Regulatory Context
VENM is defined and regulated under environmental protection and waste management frameworks.
In New South Wales, VENM is classified in accordance with EPA waste classification guidelines, which set out specific criteria for determining whether material qualifies as VENM. Similar regulatory frameworks apply in other Australian jurisdictions.
Regulators expect VENM classification to be supported by appropriate assessment and documentation.
