Environmental Impact Assessment Reports


Environmental impact assessment reports evaluate the environmental implications of actions by federal, state, and other governmental agencies. This research guide lists 1) resources covering federal and California environmental assessment laws and methodology and 2) resources for locating environmental assessment reports in the HSU Library, in other libraries and institutions, and on the Internet. For further assistance please contact Robert Sathrum, Natural Resources Librarian.

 


Federal Environmental Impact Assessement Reports


Federal requirements for assessing the environmental impact of federal projects date from 1970 with the enactment of the National Environmental Policy Act of 1969. NEPA requires every federal agency responsible for a project funded with federal funds to assess the project's potential impact on the environment. A flow chart of the federal process is available as well as a brief Overview of NEPA Requirements.

As an initial step in the environmental review process an Environmental Assessment may be prepared that determines whether an full environmental review is needed or just a Finding of No Significant Impact (FONSI) which indicates that there will be no adverse effects on the environment. If the initial review determines that there will be a significant impact a Draft Environmental Impact Statement (EIS) is prepared and made available to the public and other agencies for review and comment. This is subsequently followed by a Final Environmental Impact Statement. The final EIS does not supercede the draft EIS because the final version typically cites information included in the draft. The final step in the process is the filing of a Record of Decision (ROD).

Since 1970 more than 25,000 federal environmental impact statements have been prepared with approximately 500 draft and final EISs completed annually. See Environmental Impact Statements Filed 1970-2006 for yearly totals and Calendar Year 2006 Filed EISs for a breakdown by federal agency.

California Environmental Impact Assessement Reports


California requirements for assessing the environmental impact of projects date from 1970 with the enactment of the California Environmental Quality Act. CEQA requires that state and local agencies consider the environmental impact of their decisions when approving a public or private project. A flow chart of the California process is available.

As an initial step in the process an Initial Study may be prepared that determines whether an full environmental review is needed or just a Negative Declaration which indicates that there will be no adverse effects on the environment. If the initial report determines that there will be a significant impact a Draft Environmental Impact Report (EIR) is prepared and made available to the public and other agencies for review and comment. This is subsequently followed by a Final Environmental Impact Report (EIR). The final EIR does not supercede the draft EIR because the final version typically cites information included in the draft. The final step in the process is the filing of a Notice of Determination (NOD).

There are approximately 500 environmental impact reports (EIRs) prepared annually under the California Environmental Quality Act. Environmental Document Filings with the State Clearinghouse lists the number of reports that have been filed annually since 1999.
