Welcome to the U.S. Navy's website for the Hawaii-Southern California Training and Testing Environmental Impact Statement/Overseas Environmental Impact Statement (EIS/OEIS).

The Navy has prepared a Final EIS/OEIS to re-evaluate potential environmental impacts associated with ongoing naval training and research, development, testing, and evaluation (hereafter referred to as “training and testing”) activities conducted within existing Navy range complexes in Hawaii and Southern California, and the transit corridor that connects them. These activities involve the use of active sound navigation and ranging (sonar) and explosives while employing marine species protective mitigation measures.

The Navy previously completed an EIS/OEIS in December 2013 for training and testing activities occurring within the Hawaii-Southern California Training and Testing EIS/OEIS Study Area from 2013 through mid-December 2018. The Navy has updated this analysis by evaluating new, relevant information, such as more recent marine mammal density data and new scientific information, as appropriate. This updated EIS/OEIS will support future training and testing activities beginning in late 2018.
