Definition
A Notice of Determination (NOD) is a CEQA document that a lead or responsible agency must file with the County Clerk of each county where the project is located, and with the State Clearinghouse, after approving or deciding to carry out a project for which it prepared or certified an Environmental Impact Report (EIR) or approved a Negative Declaration or Mitigated Negative Declaration. The NOD requirement is established in Public Resources Code § 21152 and CEQA Guidelines § 15094.
The NOD is not an approval document — it is a notice that an approval has occurred and that environmental review was completed. Its primary function is to trigger the statute of limitations on CEQA legal challenges.
What the NOD Must State
The NOD must include:
- A description of the project
- The project's location
- A statement of the determination of the lead or responsible agency
- The date of approval of the project
- Whether the project will have a significant effect on the environment
- Whether an EIR was prepared or a Negative Declaration was approved
- Whether mitigation measures were made conditions of project approval
- Whether findings were made under CEQA § 21081 (findings of overriding consideration or infeasibility)
- The address where the EIR or Negative Declaration is available for public review
The Critical Statute of Limitations Function
Filing an NOD starts a 30-day statute of limitations for CEQA challenges to the project approval. This is one of the shortest statutes of limitations in California law. If no NOD is filed, the default limitations period is 180 days — six times longer. For a large project, six additional months of legal exposure can mean enormous financial risk. Timely NOD filing is therefore one of the most cost-effective risk management steps available to lead agencies after project approval.
Notice of Exemption (NOE) vs. NOD
A related but distinct document is the Notice of Exemption (NOE), filed when a project is determined to be categorically or statutorily exempt from CEQA — no EIR or Negative Declaration is required. Like the NOD, filing an NOE triggers a shorter statute of limitations (35 days) on challenges to the exemption determination. If the NOE is not filed, the default 180-day period applies.
Failing to file an NOD or NOE on time is one of the most preventable — and expensive — CEQA compliance errors agencies make. It leaves projects vulnerable to CEQA challenges for months longer than necessary. Legislaide reviews agency CEQA compliance workflows to ensure NOD and NOE filing procedures are systematized and timely.
Frequently Asked Questions
What is a Notice of Determination?
A Notice of Determination (NOD) is the CEQA document a lead agency files with the County Clerk and State Clearinghouse after approving a project for which it prepared or certified an EIR or Negative Declaration. It is a notice that an approval occurred and CEQA review was completed — not the approval itself.
What must a Notice of Determination include?
The NOD must include: the project description and location, the date of approval, whether significant environmental effects were found, which CEQA document was used, whether mitigation conditions were imposed, whether findings of overriding consideration were made, and where the environmental document is available for public review.
Why is filing a Notice of Determination so important?
Filing an NOD starts a 30-day statute of limitations on CEQA challenges. Without an NOD, the default limitation period is 180 days — six times longer. For large projects, six extra months of litigation exposure represents substantial financial and schedule risk that is easily avoided by timely filing.
What is the difference between a Notice of Determination and a Notice of Exemption?
An NOD is filed when the agency prepared a CEQA document (EIR or Negative Declaration). A Notice of Exemption (NOE) is filed when the project is CEQA-exempt — no environmental document was required. An NOE triggers a 35-day limitation period; an NOD triggers 30 days. Both reduce exposure compared to the 180-day default.
What happens if an agency fails to file a Notice of Determination?
If an NOD is not filed, the 180-day default statute of limitations applies — giving potential challengers six months to file suit. This extended exposure window is easily and cheaply preventable by filing the NOD promptly. Agencies that skip NOD filing unnecessarily increase their CEQA litigation risk.
