OAR 141-142-0015
Definitions
(1)
“Authorization” means a lease, registration, short-term access authorization, temporary use authorization, public facility license, easement or other authorization the Department grants that allows a person to use, or place a structure in, on, under or over state-owned submerged land, state-owned submersible land, or both in the Territorial Sea.(2)
“Department” means the Department of State Lands.(3)
“Disturbance” means the extraction of living organisms and non-living materials, or human induced changes to the environment.(4)
“Extractive Activity” means any human effort to remove or attempt to remove any living or non-living marine resource.(5)
“Extreme Low Water” or “ELWL” means the lowest elevation reached by the sea as recorded by a water level gauge during a given period. Extreme low water is generally seaward of the “line of ordinary low water” as defined in ORS 274.005 (Definitions)(3).(6)
“Marine Protected Area” means any area of the marine environment within Oregon’s Territorial Sea that has been reserved by the state to provide lasting protection for part or all of the natural and cultural resources therein.(7)
“Marine Reserve” is an area within Oregon’s Territorial Sea or adjacent rocky intertidal area that is protected from all extractive activities, including the removal or disturbance of living and non-living marine resources, except as necessary for monitoring or research to evaluate reserve condition, effectiveness, or impact of stressors.(8)
“Mean High Water” or “MHWL” is a tidal datum. It is the average of all the high water heights observed over the National Tidal Datum Epoch. For stations with shorter series, comparison of simultaneous observations with a control tide station is made in order to derive the equivalent datum of the National Tidal Datum Epoch. For purposes of the Department’s jurisdiction, Mean High Water corresponds generally with the “line of ordinary high water” as defined in ORS 274.005 (Definitions)(3).(9)
“National Tidal Datum Epoch” means the specific 19-year period adopted by the National Ocean Service as the official time segment over which tide observations are taken and reduced to obtain mean values (e.g., mean lower low water, etc.) for tidal datums. It is necessary for standardization because of periodic and apparent secular trends in sea level. The present National Tide Datum Epoch is 1983 through 2001 and is actively considered for revision every 20-25 years. Tidal datums in certain regions with anomalous sea level changes are calculated on a Modified 5-Year Epoch.(10)
“Removal-Fill Permit” means an authorization granted by the Department governing the removal, fill, alteration, or any combination thereof of material within the waters of the State of Oregon as provided in ORS 196.668 (Legislative findings) to 196.692 (Rules) and ORS 196.800 (Definitions for ORS 196.600 to 196.921) to 196.990 (Penalties).(11)
“Seabird Protection Area” is an area within Oregon’s Territorial Sea that has been reserved by the state for the protection of seabirds.(12)
“State Land” as provided in ORS 273.006 (Definitions)(8) means public land controlled by the Department.(13)
“Structure” means anything placed, constructed, or erected in, on, under or over state-owned submerged and submersible land.(14)
“Submerged Land” as provided in ORS 274.005 (Definitions)(7), means lands lying below the line of ordinary low water of all navigable waters within the boundaries of this state as heretofore or hereafter established, whether such waters are tidal or nontidal, except as provided in 274.705 (Definitions for ORS 274.705 to 274.860).(15)
“Submersible Land” as provided in ORS 274.005 (Definitions)(8), means lands lying between the line of ordinary high water and the line of ordinary low water of all navigable waters and all islands, shore lands or other such lands held by or granted to this state by virtue of her sovereignty, wherever applicable, within the boundaries of this state as heretofore or hereafter established, whether such waters or lands are tidal or nontidal, except as provided in 274.705 (Definitions for ORS 274.705 to 274.860).(16)
“Territorial Sea” as provided in ORS 196.405 (Definitions for ORS 196.405 to 196.515)(5), means the waters and seabed extending three nautical/geographical miles seaward from the coastline in conformance with federal law.(17)
“Territorial Sea Plan” as provided in ORS 196.405 (Definitions for ORS 196.405 to 196.515)(6), means the plan for Oregon’s Territorial Sea. In addition to the Territorial Sea as defined in section (15), the scope of the Territorial Sea Plan includes the “ocean shore” as defined in 390.605 (Definitions).
