Potential environmental impacts of the herring fishery are addressed each year in an environmental document, in accordance with the California Environmental Quality Act (CEQA). The Supplemental Environmental Document for Pacific Herring Commercial Fishing Regulations reviews and evaluates proposed regulatory changes for the current fishing season, supplementing and in some cases replacing aspects of the proposed project described in the 1998 Final Environmental Document (FED) and the Final Supplemental Environmental Documents of the prior herring season. There was no Supplemental Environmental Document for 2003 or 2012.
