Thank you for visiting the National Environmental Policy Act (NEPA) website Information. This website was created to promote outreach efforts by making project information readily available and allows the public to participate in the NEPA process. NEPA was signed into law by President Nixon on January 1, 1970. NEPA requires Federal Agencies to assess the environmental effects of their proposed actions prior to making decisions. To implement NEPA's policies, Congress prescribed a procedure, commonly referred to as "the NEPA process" or "the environmental impact assessment process."
The Department of the Navy (DON) executes the NEPA process using its Procedures for Implementing NEPA found in Title 40, Code of Federal Regulations (CFR), Part 775; SECNAVINST 5090.6A; OPNAVINST 5090.1C CH-1; and Marine Corps Order P5090.2A CH-2. This process consists of an evaluation of the environmental effects of an undertaking including its alternatives. The process involves three levels of analysis: Categorical Exclusion (CATEX); Environmental Assessment (EA) and Finding of No Significant Impact (FONSI); Environmental Impact Statement (EIS) and Record of Decision (ROD).
Executive Order 12114 applies to a proposed action that will occur overseas. In this case, the DON develops a Record of Negative Decision, an Overseas Environmental Assessment (OEA), or an Environmental Impact Statement (OEIS).
NAVFAC helps determine when Navy and Marine Corps actions require a CATEX determination, EA, or EIS. NAVFAC conducts in-house or contracts for the thorough environmental analyses and supporting studies necessary to prepare these documents.
