Categorical Exemption
Type, Section or Code
15306, Class 6 (Information Collection)
Reasons for Exemption
CEQA Guidelines Section 15306, Class 6, consists of basic data collection, research, experimental management, and resource evaluation activities which do not result in a serious or major disturbance to an environmental resource. These may be strictly for information gathering purposes, or as part of a study leading to an action which a public agency has not yet approved, adopted, or funded. Therefore, further review under CEQA is not required.
Exempt Status
Statutory Exemption
Type, Section or Code
15262 (Feasibility and Planning Studies)
Reasons for Exemption
CEQA Guidelines Section 15262 indicates that a project involving only feasibility or planning studies for possible future actions which the agency, board, or commission has not approved, adopted, or funded does not require the preparation of an EIR or negative declaration but does require consideration of environmental factors. This section does not apply to the adoption of a plan that will have a legally binding effect on later activities. Therefore, further review under CEQA is not required.
