Navy Issues Record of Decision for Hawaii-Southern California Training and Testing Environmental Impact Statement

By U.S. Pacific Fleet Public Affairs U.S. Pacific Fleet

The U.S. Navy issued a Record of Decision (ROD) Dec. 23 for the Hawaii-Southern California Training and Testing (HSTT) Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS). 

Following several years of research, environmental analysis, and public involvement, the Navy has chosen Alternative 2, the Preferred Alternative described in the HSTT Final EIS/OEIS, to accomplish the Proposed Action. This alternative includes establishment of new range capabilities, adjustments to the types and levels of training and testing and modifications to existing capabilities. 

The Navy's Proposed Action is to conduct training and testing activities - which will include the use of active sonar and explosives - throughout the in-water areas around the Hawaiian Islands, off the coast of Southern California, in the transit corridor between Hawaii and Southern California, and at Navy pierside locations. The Proposed Action also includes sonar maintenance and gunnery exercises conducted concurrently with ship transits as well as pierside testing conducted as part of overhaul, modernization, maintenance and repair activities at Navy piers located in Hawaii and Southern California. 

"This EIS was developed with the best available science and will enable the Navy to continue training and testing in Hawaii and Southern California while minimizing potential injury to the environment, as we have safely done for more than 60 years," said Alex Stone, senior environmental planner for the U.S. Pacific Fleet and HSTT EIS project manager. "This training and testing is essential for the fleet to fulfill its mission of defending the nation and the global commons and leading America's rebalance to the Indo-Asia-Pacific." 

The Navy prepared the EIS/OEIS to assess potential environmental impacts from its training and testing activities and to support authorizations, permits and consultations required under the Endangered Species Act, Marine Mammal Protection Act, and other relevant statutes.

The ROD is now available to the public. The document and the HSTT Final EIS/OEIS can be found online at
