Directs DEP to establish sonar testing permit program.

This bill requires New Jersey's Department of Environmental Protection (DEP) to create a permit program for sonar testing in state waters. It directly affects entities conducting sonar testing (like research or industry groups), except for the military or emergency situations. Applicants must submit a study assessing impacts on marine life and mitigation plans before receiving a permit, which is valid for one year. The DEP must suspend permits immediately if sonar causes marine mammal harm and investigate the incident, with findings published online.
