National Environmental Policy Act (NEPA) Process

Training and Testing in the HSTT Study Area

Environmental Stewardship

Welcome

Welcome to the United States (U.S.) Department of the Navy's Hawaii-Southern California Training and Testing (HSTT) environmental planning website.

The HSTT website is an online resource for information concerning the potential environmental effects of training and testing (military readiness) activities that occur in the high seas areas located in the Pacific Ocean along the coast of California, in the waters around the Hawaiian Islands, and within California and Hawaii inland waters such as Navy and Civilian Ports.

The third (Phase III) comprehensive review of potential environmental effects of military readiness activities was published in October of 2018. The HSTT Environmental Impact Statement (EIS)/Overseas Environmental Impact Statement (OEIS) supported authorization by the National Marine Fisheries Service, as a cooperating agency, of incidental takes of marine mammals under the Marine Mammal Protection Act and incidental takes of threatened and endangered marine species under the Endangered Species Act.

It is anticipated that a follow-on National Environmental Policy Act (NEPA) analysis will begin in 2023 to support renewal of current federal regulatory permits and authorizations that expire in December of 2025. Registered Subscribers will receive email status updates.
