2022 Stage 14 amendments
The Stage 14 amendments to the CSR include:
- A new process for soil relocation
- Minor amendments to site identification
- Housekeeping amendments to the schedules
The changes to soil relocation help streamline the legal regime, making the process clearer and more transparent and improve the ministry’s ability to carry out compliance verification and enforcement.
The changes to site identification and Schedules 1 and 2 ensure the Stage 13 amendments operate as intended.
The CSR amendments were deposited on June 6, 2022. Changes to soil relocation come into effect on March 1, 2023.
Approved amendments to EMA and the CSR:
- Environmental Management Amendment Act (2020) (Bill 3)
- Contaminated Sites Regulation Ministerial Order 164/2022
2021 Stage 13 amendments
Stage 13 amendments to the CSR included changes to the current process for identifying contaminated sites.
These changes strengthen and streamline the legal regime, making the process clearer and more predictable and improve the ministry’s ability to carry out compliance verification and enforcement.
This ensures that contaminated sites are investigated and remediated in a timely manner, following site closure and prior to redevelopment:
