WHAT DOES THIS TOPIC INCLUDE?
This chapter discusses the criteria that a project must meet to be exempt from the California Environmental Quality Act and the preparation and processing of the Categorical Exemption (CE) documentation for Caltrans projects. Local Agencies may find this guidance useful for CEQA compliance for transportation projects for which they are the CEQA lead agency.
CATEGORICAL EXEMPTION DECISION TREE
LAWS, REGULATIONS, AND GUIDANCE
- See also Chapter 2 - State Requirements- The California Environmental Quality Act of 1970 [Public Resources Code, Division 13, Sections 21000 et seq.]
- Guidelines
for the Implementation of the California Environmental Quality
Act

- Department of Transportation Regulations for Implementation of the California Environmental Quality Act of 1970 [Title 21 CCR, Chapter 11, Section 1501 et . seq.]
- Guidance for Determining CEQA Lead Agency Status for Project on the State Highway System
DEFINITION OF A CEQA PROJECT
The first step in determining whether a public agency action is subject to the provisions of CEQA is to determine whether the action is a "project", as defined by CEQA (PRC Section 21065 and CEQA Guidelines Section 15378). The Guidelines define a "project" as the whole of an action, which has a potential for resulting in either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment, and that is …an activity directly undertaken by any public agency including … public works construction and related activities. Under CEQA, "projects" must be discretionary, public agency actions which have the potential of affecting the environment.
TYPES OF AGENCIES UNDER CEQA
A Lead Agency is the public agency that has the principal responsibility for carrying out or approving a project. The Department is the lead agency for its own projects. The Department may also be lead agency for private projects that require Department approval, for example, a private telecommunications company proposing to install equipment with the Department’s right-of-way.
A responsible agency is any public agency other than the Department that has discretionary approval power over the project. A trustee agency means a state agency having jurisdiction by law over natural resources affected by a project that are held in trust for the people of the State of California. Trustee agencies include:
- The California Department of Fish and Game with regard to the fish and wildlife of the state, to designated rare or endangered native plants, and to game refuges, ecological reserves, and other areas administered by the department;
- The State Lands Commission with regard to state owned "sovereign" lands such as the beds of navigable waters and state school lands;
- The State Department of Parks and Recreation with regard to units of the State Park System;
- The University of California with regard to sites within the Natural Land and Water Reserves System.
Common examples of responsible agencies include: the Regional Water Quality Control Board for its Section 401 Water Quality Certification, the Department of Fish and Game for its Section 1602 Lake or Streambed Alternation Agreement, the Office of Historic Preservation for its concurrence on affected cultural resources.
The Department can also be a responsible agency for non-Department projects that impact the Department’s facilities, for example, where a city will need to obtain an encroachment permit for conducting work within the Department’s right-of-way.
Responsible agencies must actively participate in the lead agency’s CEQA process and consider the lead agency’s environmental document prior to acting upon or approving the project. The responsible agency must certify that it reviewed and considered the information contained in the lead agency’s CEQA document. The responsible agency must also prepare and issue its own findings regarding the project.
Generally, a responsible agency must accept the lead agency’s environmental document as legally adequate. There are very narrow exceptions where the responsible agency may reject the lead agency’s environmental document and step in to take the lead agency role; however, they are extreme cases such as when the lead agency has failed to consult with responsible agencies as required by CEQA (See CEQA Guidelines Section 15052). Therefore, responsible agencies must participate early and actively in the lead agency’s CEQA process to ensure its concerns are met.
MINISTERIAL ACTIONS
One first must determine whether a public agency action is ministerial. A ministerial action is a governmental decision involving little or no personal judgment by the public official as to the wisdom or manner of carrying out the project. The public official merely applies the law to the facts as presented but uses no special discretion or judgment in reaching a decision. Such decisions use a series of fixed standards or objective measurements, and does not involve the use of personal or subjective judgments in deciding whether or how the project should be carried out. Examples of ministerial projects would include automobile registrations and some building permits limited to determining proper zoning. Ministerial actions, by definition, are not “projects” because they are not discretionary actions by a public agency.
Secondly, one must determine whether the project is exempt from CEQA by statute.
STATUTORY EXEMPTIONS
The California Legislature has the power to create exemptions from the requirements of CEQA, and projects which fall under such exemptions can be made wholly or partially exempt, as determined by the Legislature. Projects that the Legislature has determined should be exempted from CEQA are found either in the statute itself and may be cross-referenced in codes other than the Public Resources Code. These actions are not subject to CEQA; however it is advisable that the Department includes documentation in the project file that offers evidence that the project is exempt by statute. The CE form can be used to describe the project and indicate that it is exempt by statute.
Examples of the statutory exemptions that may apply to the Department’s activities include emergency exemptions (see below); the establishment or modification of tolls; a project for the institution or increase of passenger or commuter services on rail or highway rights-of-way already in use, including modernization of existing stations and parking facilities; a project for the institution or increase of passenger or commuter service on high-occupancy vehicle lanes already in use, including the modernization of existing stations and parking facilities; facility extensions not to exceed four miles in length which are required for the transfer of passengers from or to exclusive public mass transit guideway or busway public transit services; a project for the development of a regional transportation improvement program, the state transportation improvement program, or a congestion management program.
EMERGENCY EXEMPTIONS
Projects which require specific actions necessary to prevent or mitigate an emergency, can qualify for an exemption under CEQA. An emergency exemption under CEQA does not necessarily remove the Department’s responsibility to comply with other state laws nor has it any bearing on compliance with federal laws. Environmental Compliance in case of emergency.
An emergency is defined as “a sudden, unexpected occurrence, involving a clear and imminent danger, demanding immediate action to prevent or mitigate loss of, or damage to, life, health, property, or essential pubic services. “Emergency” includes such occurrences as fire, flood, earthquake, or other soil or geologic movements, as well as such occurrences as riot, accident, or sabotage.” The concept of “emergency” should be interpreted narrowly and would include such projects as the following:
- Projects to maintain, repair, restore, demolish, or replace property or facilities damaged or destroyed as a result of a disaster in a disaster stricken area in which a state of emergency has been proclaimed by the Governor pursuant to the California Emergency Services Act. This includes projects that will remove, destroy, or significantly alter an historical resource when that resource represents an imminent threat to the public of bodily harm or of damage to adjacent property or when the project has received a determination by the State Office of Historic Preservation pursuant to Section 5028 (b) of Public Resources Code.
- Emergency repairs to publicly or privately owned service facilities necessary to maintain service essential to the public health, safety or welfare.
- Specific actions necessary to prevent or mitigate an emergency. This does not include long-term projects undertaken for the purpose of preventing or mitigating a situation that has a low probability of occurrence in the short-term.
- Projects undertaken, carried out, or approved by a public agency to maintain, repair, or restore an existing highway damaged by fire, flood, storm, earthquake, land subsidence, gradual earth movement, or landslide, provided that the project is within the existing Right-of-Way of that highway and is initiated within one year of the damage occurring. This exemption does not apply to highways designated as official state scenic highways, nor any project undertaken, carried out, or approved by a public agency to expand or widen a highway damaged by fire, flood, storm, earthquake, land subsidence, gradual earth movement, or landslide.
- Seismic work on highways and bridges pursuant to Section 180.2 of the Streets and Highways Code section 180 et seq.
EXCEPTIONS TO CATEGORICAL EXEMPTIONS
If the project is determined to be categorically exempt, the Department must consider whether the exemption is negated by an exception pursuant to CEQA Guidelines, Section 15300, and Public Resources Code, Section 21084. Such exceptions may apply under the following circumstances:
- The project site is environmentally sensitive as defined by the project’s location. A project that is ordinarily insignificant in its impact on the environment may in a particularly sensitive environment be significant.
- The project and successive projects of the same type in the same place will result in cumulative impacts;
- There are “unusual circumstances” creating the reasonable possibility of significant effects;
- The project may result in damage to scenic resources, including, but not limited to, trees, historic buildings, rock, outcroppings, or similar resources, within an officially designated scenic highway, except with respect to improvements required as mitigation for projects for which negative declarations or EIRs have been prepared;
- The project is located on a site that the Department of Toxic Substances Control and the Secretary of the Environmental Protection have identified, pursuant to Government Code section 65962.5, as being affected by hazardous wastes or clean-up problems; or
- The project may cause a substantial adverse change in the significance of an historical resource.
CATEGORICAL EXEMPTIONS
The Secretary of the Resources Agency prepares and adopts a list of
classes of projects which have been determined not to have a significant
effect on the environment and are considered “exempt” from
CEQA. These classes are known as “categorical exemptions.” However,
a categorical exemption is conditioned by limitations defined in the
Guidelines and by the statutory authorization limiting such exemptions
to projects with no significant environmental effect. The Environmental
Branch Chief decides whether a project is eligible for a categorical
exemption as part of the preliminary review of the project. The Department
documents its determination that a project meets the criteria of a
categorical exemption by completing the CE form and retaining it in
the project file. Here is a link to the current list of Categorical
Exemption
classes
in the CEQA Guidelines. (Note: the current list of exemption classes
begins at Section 15301.)
PREPARING AND PROCESSING EXEMPTIONS
Documenting a CEQA Exemption
The appropriate CE form must be completed and shall include:
- A brief description of the project.
- A finding that the project is exempt from CEQA, including documentation of which class, rule, or statute.
- A brief statement of reasons to support the finding.
- Document signatures by the Project Manager and the Environmental Branch Chief.
The CE form must be retained in the Project file along with any documentation to support its conclusions.
Notice of Exemption
When the Environmental Office Chief of a District office determines that a project is exempt from CEQA and gives approval to carry out the project, the District Environmental office may file a Notice of Exemption (NOE) with the State Clearinghouse and with the county clerk of each involved county.
Filing an NOE triggers a 35-day statute of limitations period on legal challenges to the agency’s decision that the project is exempt from CEQA. If an NOE is not filed, the statute of limitations period becomes 180 days.

The NOE, if filed, shall not be filed with the Office of Planning and Research (OPR) (or the county clerk for Local Agency projects) until the project has been approved. If a NOE will be filed, the procedures outlined below should be followed:
- The notice is filed with the OPR. A form for this notice can be
found in the CEQA Guidelines, Appendix E. An
online version for the form is available from the OPR website.
[Note:
You need to have Adobe Acrobat installed on your computer to save
your changes; if you have Acrobat Reader you will not be able to
save any changes to the form.] The notice is posted for a period
of 30 days. - When a local agency files this notice, the NOE is filed with the county clerk of each county in which the project will be located. Copies of all such notices shall be available for public inspection and such notices shall be posted within 24 hours of receipt in the office of the county clerk. Each notice shall remain posted for a period of 30 days. Thereafter, the clerk shall return the notice to the local agency with a notation of the period it was posted. The local agency shall retain the notice for not less than 9 months.
- All public agencies are encouraged to make postings pursuant to this section available in electronic format on the Internet. Such electronic postings are in addition to the procedures required by these guidelines and the Public Resources Code.
The filing of a NOE and the posting on the list of notices start a 35 day statute of limitations period on legal challenges to the agency's decision that the project is exempt from CEQA. If a Notice of Exemption is not filed, a 180 day statute of limitations will apply.
