The purpose of the Standard Environmental Reference (SER) is to provide a single, standard reference on compliance with the National Environmental Policy Act (NEPA) and related federal laws, executive orders, regulations, and policies. The reference is intended for statewide use by local agencies, Caltrans, and FHWA staff. The SER also provides information on compliance with the California Environmental Quality Act (CEQA) and related state laws, executive orders, and regulations. This information is for use by Caltrans in the preparation of environmental documentation for on projects for which it is the CEQA lead agency. Local agencies, acting as lead for CEQA on their own projects, may also wish to refer to these portions of the SER for guidance and ideas supplemental to their own procedures.
