Public Rule Hearings
For decades, cables have been installed on the bottom of Oregon’s territorial sea—the area of the Pacific Ocean extending from the shoreline to three nautical miles offshore. These cables, often called “undersea” or “submarine” cables, carry global data through optical fibers and are placed on, attached to, or buried beneath the seafloor. In the future, similar infrastructure may also include power transmission cables and pipelines to serve purposes like carrying electricity from offshore wind turbines to shore. DSL, with approval from the State Land Board, issues easements for use of the territorial sea.
DSL is one of several agencies with a regulatory role in the territorial sea, but the administrative rules guiding DSL’s work are out of date.
Oregon’s administrative rules governing these easements have not been comprehensively updated in 25 years. Since then, undersea infrastructure technology has evolved significantly, including the development of SMART cables that support both data transmission and sensors for ocean monitoring. In addition, Oregon’s Territorial Sea Plan Part Four was updated in 2023, and Senate Bill 793 now requires DSL to set application and compensation fees for easements associated with water, gas, electric, and communication infrastructure in the territorial sea. These changes in technology, policy, and state law make updates to the rules necessary.
