B. At least 24 hours prior to the commencement of dredging operations, Contractor shall allow the Port Engineer or designee to observe the Contractor’s equipment. Contractor shall correct any equipment deficiencies prior to the start of dredging. C. All rubbish, garbage, and other discarded solid material resulting from dredging operations shall be retained in containers until removal by the Contractor for recycling or upland disposal at an approved licensed landfill. D. All chemical waste from the dredge, such as oil and grease, shall be retained in tanks or containers designed and approved for that use and pumped off or otherwise properly removed for proper disposal by Contractor. E. To protect rock fill and fender piles, no dredge material shall be removed below the Required Dredge Elevation within 10 feet of any pier face. F. During the dredging, a steel grid "grizzly" with twelve inch square maximum openings shall be placed over the ▇▇▇▇▇▇ of the dump scow for material processing. All dredged material shall be dropped onto the grid. Details of the "grizzly" are subject to U.S. Army Corps of Engineers approval via approval of the Dredging Operations Manual.
