Ohmsett is the National Oil Spill Response & Renewable Energy Test Facility, located in Leonardo, New Jersey.

A benefit of this facility is that it provides an environmentally safe place to conduct objective testing and to develop devices and techniques for the control of oil and hazardous material spills.

[2] The mission of Ohmsett is to strengthen awareness of oil spill pollution prevention and response methods, while at the same time remaining committed to the well being of its customers, employees, and associates.

The facility, located an hour south of New York City, located on the ground of Naval Weapons Station Earle in Leonardo, New Jersey, is maintained and operated by the Bureau of Safety and Environmental Enforcement (BSEE), a bureau of the U.S. Department of the Interior that manages the nation's natural gas, oil and other mineral resources on the outer continental shelf (OCS).

Because of this, no appropriated taxpayer dollars are used to support this unique oil spill response technology testing, training, and research facility.
