Do you own or operate a site anywhere in Australia? If it is contaminated, you will now face a double dose of regulatory red tape. From 1 July 2026, the federal NEPA introduces the EPBC Act, which brings forth strict oversight and massive penalties for contaminated sites on top of state EPA rules. Keep your site safe from regulatory penalties. Assess and remediate it now to ensure total federal compliance.
Key Takeaways
- Dual-Regulatory Oversight: From 1 July 2026, site owners will face a two-tiered regulatory environment, answering to both their state EPA and the newly formed federal National Environmental Protection Agency (NEPA)
- Enhanced Enforcement Powers: NEPA holds the authority to issue verbal or written Environment Protection Orders (EPOs) to halt works immediately, mandate compliance audits, and prosecute offences in the Federal Court
- Proactive Compliance is Vital: Managing high-risk contaminants (like PFAS, asbestos, and heavy metals) through Phase 1/2 assessments and Remedial Action Plans (RAPs) is now critical to avoid project shutdowns
The National Environmental Protection Agency (NEPA) will finally commence operations from 1st July, 2026. The first environmental protection agency that will be working at the federal level. Here, the Environment Protection and Biodiversity Conservation Act 1999 (Cth) (EPBC Act) will cover all new reformed laws and their implementation.
All these years of weak enforcement end, and now site owners will have to face a second regulator on top of the state EPA regulations. For you, your potentially contaminated site will be under greater scrutiny, with regulated due diligence oversight and increased compliance obligations. Read on to know what it means for contaminated sites.
What is NEPA?
Consultation papers were already released, seeking feedback on supporting the establishment of NEPA. It will be working independently, and there is no minister’s discretion enforced yet. It originated from the 2020 Samuel Review, which declared the EPBC Act “outdated and not fit for purpose”. Now the reformed EPBC Act under environmental legislation in Australia covers the following:
- The Environment Protection Reform Act 2025 (Cth) (Reform Act)
- The National Environmental Protection Agency Act 2025 (Cth) (NEPA Act)
- The Environment Information Australia Act 2025 (Cth) (EIA Act)
- The Environment Protection and Biodiversity Conservation (Restoration Charge Imposition) Act 2025 (Cth) (Restoration Charges Imposition Act).
Furthermore, NEPA has the power to:
- Issue environmental protection orders
- Enforce penalties for environmental breaches, and
- Conduct environmental assessments and audits to ensure compliance.
It can also make project approval decisions, but only as a delegate of the Environment Minister, not independently. The Minister retains ultimate responsibility only for project approval decisions.
Overall, this does not replace state/territory EPAs as it co-exists with the existing regulations. It’s just that site owners will face dual environmental legislation oversight from this year onwards.
How NEPA Changes the Game for Contaminated Sites
There will be new regulations on environmental protection, enforcement powers, increased penalties, compliance audits, federal court involvement, and National Environment Standards (NES) implementation.

NEPA Power |
What It Means for Site Owners | Legislative Source |
|---|---|---|
| Environment Protection Order (EPO) | Works can be halted verbally or in writing if the NEPA CEO determines imminent or likely environmental harm; this applies even where work has already commenced |
Environment Protection Reform Act 2025 (Cth) |
|
Compliance Audit Power |
NEPA can direct any person connected to a project to undergo a mandatory compliance or environmental audit, broader than prior EPBC Act audit powers | NEPA Act 2025/EPBC Act s.515AAA |
| Federal Court Prosecution | NEPA investigates and prosecutes EPBC Act offences in the Federal Court; penalties beyond state-level infringement notices |
NEPA Act 2025, commencement 1 July 2026 |
|
National Environmental Standards (NES) |
Binding standards set by Minister; approvals must be consistent with NES unless national interest exception applies; standards for MNES and offsets already in draft | EPBC Act Part 17/Reform Act 2025 |
| Increased Civil Penalties | New civil penalty formula applies to all contraventions from 1 July 2026 onward; precedent set by $55M penalty against Alcoa for land clearing under the former Act |
Reform Act 2025 (Cth) |
|
Environment Information Australia (EIA) |
New data body commencing 1 July 2026 collects and publishes environmental data, increasing transparency around site conditions and contamination records |

What This Means for Contaminated Site Owners
Sites with EPBC approval conditions will now be actively monitored by NEPA, and non-compliance will trigger federal action, not just state.
- Due diligence gaps are now high-risk, and undisclosed contamination discovered during a NEPA-monitored project can halt operations
- PFAS, heavy metals, hydrocarbons, and asbestos in soil usually trigger regulatory action under state laws, and now NEPA adds a federal compliance layer
- NEPA increases the need for Phase 1/Phase 2 environmental assessments and validated Remedial Action Plans (RAPs) before settlement
- The polluter pays principle (PPP) is now applicable by the federal body, making landowners who contributed to contamination face stricter regulations
State vs Federal Regulatory Coordination

Be Ready for the NEPA Supervision of Your Site
Don’t wait for state or federal councils to flag your site and deliver an EPO. Do not start projects before site remediation. Contact SERS for a pre-NEPA site compliance review if you are not sure what the EPBC Act is. SERS will be your compliance-ready partner, helping you with site assessments, RAPs, compliance monitoring, and environmental audits, all aligned to the new federal NEPA framework. Consult us now for a site assessment!
Frequently Asked Questions
Will NEPA Regulate Historic Contamination Where the Polluter Cannot Be Found?
Yes. If the original polluter cannot be identified, the current landowner typically inherits the compliance and remediation obligations under NEPA.
How Will NEPA Impact Property Valuations and Transactions?
Stricter federal compliance risks lower valuations for unremediated land due to increased liability, making thorough pre-purchase due diligence absolutely critical.
Can a State EPA Approval Override a NEPA Enforcement Order?
No. NEPA operates independently at the federal level; state approvals do not exempt site owners from federal compliance obligations.
What Funding or Grants Are Available Under the New Framework for Site Remediation?
The current legislation focuses heavily on enforcement and cost recovery rather than federal funding, leaving remediation costs to site owners.
