    Acid sulfate soil

    Victoria: The soil assessment identifies acid sulfate conditions.

    When to use N123
Victoria uses N123 when the soil assessment finds acid sulfate conditions in excavated soil.

When is acid sulfate soil N123 rather than N120?

In Victoria, N123 covers actual and potential acid sulfate soil that stays within the fill-material contamination limits and has no asbestos. Soil with that other contamination goes to the contaminated-soil assessment.

What changes when potential acid sulfate soil is excavated?

Exposure to oxygen and water can generate sulfuric acid. Victorian guidance puts avoiding disturbance, minimising disturbance and preventing oxidation ahead of treatment or off-site disposal. Plan management before excavation, not after choosing a code.

Which exclusions or special routes apply to acid sulfate soil waste codes?

New South Wales. NSW’s published resource recovery provisions include an order and an exemption for acid sulfate soil.

The shared classification and movement limits for acid sulfate soil waste codes are on the Victoria, New South Wales, Queensland, South Australia, Western Australia, Tasmania, Australian Capital Territory and Northern Territory pages.

What do you do next with acid sulfate soil waste codes?

For acid sulfate soil, plan excavation and treatment first. Then use the state soil approval or reuse route that fits the test results and destination.
