6.0 Impact Considerations Version :27.10.4 <br /> Sheltered, Solid Man-made Structures <br /> • Description <br /> . These are structures such as seawalls, groins, revetments, piers, and port <br /> facilities, constructed of concrete, wood, or metal. <br /> . Most structures are designed to protect a single lot, thus their composition, <br /> design, and condition are highly variable. <br /> . Often there is no exposed beach at low tide, but multiple habitats may be <br /> present. <br /> . There can be dense attachments of animal and plant life. <br /> . They are common in developed waterfront areas. <br /> • Predicted Oil Behavior <br /> . Oil will adhere readily to the rough surface, particularly along the high-tide line, <br /> forming a distinct oil band. <br /> . The lower intertidal zone usually stays wet (particularly if algae-covered), <br /> preventing oil from adhering to the surface. <br /> . Response Considerations <br /> . Seawalls are usually cleaned for aesthetic reasons or to prevent leaching of oil. <br /> • Low- to high-pressure spraying at ambient water temperatures is most effective <br /> when the oil is fresh. <br /> Shell Supply and Distribution 6-46 Stockton Terminal FRP <br /> ©2019 Witt O' Brien's Revision Date:October, 2019 <br />
