B -- A NUMERICAL MODELING EVALUATION OF THE CUMULATIVE PHYSICAL EFFECTS OF OFFSHORE SAND DREDGING FOR BEACH NOURISHMENT SOL 1435-01-99-RP-3993 DUE 040599 POC J. Callas, Contracting Officer or L. Donley, Procurement Assistant: (703) 787-1354 E-MAIL: Contracting Officer and Procurement Assistant E-mail, Jaci.Callas@mms.gov AND Lane.Donley@mms.gov. The United States (U. S.) Government, and specifically, the Minerals Management Service (MMS), a bureau within the U. S. Department of the Interior, has jurisdiction over all mineral resources on the Federal Outer Continental Shelf (OCS), a zone which extends from three miles seaward of the coastal State boundaries out to two hundred miles. Until recently only oil and gas resources were harvested from within this area. However, the potential for exploitation of sand resources located on the OCS as a source of material for beach and barrier islands restoration has grown rapidly in the last several years as similar resources in State waters are being depleted or polluted. Several OCS areas are also being examined as possible sources of aggregate for construction purposes. Resources in U. S. Federal waters may also be environmentally preferable, due to concerns over changes in resident physical oceanographic conditions as large quantities of material are extracted from areas within the existing wave base.This has generated a need for technical information and environmental studies to ensure that offshore minerals are developed in a safe and environmentally sound manner. The MMS' International Activities and Marine Minerals Division (INTERMAR) has been developing and procuring contracts to provide needed environmental information in regards to environmental management of these resources. This request for proposal (RFP) is in accordance with the FY99 National Studies List (NSL), #NT99-1 entitled "A Numerical Modeling Evaluation of the Cumulative Physical Effects of Offshore Sand Dredging for Beach Nourishment". This RFP addresses the need for environmental information to support potential lease decisions offshore the east coast of the U.S. from northern New Jersey to central Florida. The objective of the twenty four (24) month study is to examine, via numerical wave refraction modeling, the potential for negative impacts to the coastal and nearshore area due to long-term dredging and significant removal of sand from the Federal shoals and sand deposits identified as potential borrow sites on the east coast of the U.S. offshore the states of New Jersey, Maryland, Delaware, Virginia, North and South Carolina, and Florida. By virtue of cooperative agreements with MMS, and in consultation with the States and the U.S. Army Corps of Engineers, the MMS has identified several potential sites of high-quality clean sand deposits in Federal waters, offshore northern New Jersey south to central Florida. The locations of these deposits will be provided to the successful offeror. The information gathered during this project will be used should decisions be made to proceed with preparation of an environmental impact statement or assessment to support negotiated agreements with the States, local jurisdictions, or other Federal Agencies for access to Federal sand resources. The information gathered during the course of this study will also enable the MMS to assess the potential impacts of long-term offshore dredging activities andto identify ways in which the dredging operations can be conducted so as to minimize or preclude long-term adverse impacts to the environment. The offeror shall provide the necessary personnel, facilities, and services required for the successful performance and completion of the study objectives set forth herein. BRIEF SUMMARY OF TASKS: Item 1 -- Wave Refraction Modeling (Task 1): The Offeror will use an existing off-the-shelf numerical wave refraction/diffraction model to study shoal response for identified areas offshore the U.S. east coast from northern New Jersey to central Florida, relative to wave energies, both normal and storm-induced, assuming that significant amounts of sand will be removed during several dredging episodes. Item2 -- Collection of Relevant Data (Task 2): Prior to initiation of any modeling work, the Offeror will collect relevant physical data necessary to run the model. Item 3 -- Preparation of the Draft and Final Technical Manuscript (Task 3): After all modeling work is complete, the Offeror shall prepare a report with clear, concise writing at a level suitable to a technical audience familiar with the various facets of the marine sciences. The document will contain all relevant modeling output as agreed upon between the Offeror and MMS. Item 4 -- Draft and Final Executive Summary (Task 4): The Offeror shall submit a draft Executive Summary. Item 5 -- Technical Draft and Final Summary (Task 5): The Offeror shall prepare a Draft Technical Summary. Item 6 -- Submission of Draft and Final Non-Technical Summary (Task 6): The Offeror shall prepare a separate draft non-technical document describing the study. Item 7 -- Submission of Scientific Paper to Refereed Journal (Task 7): After completion and acceptance of the final manuscript, the Offeror shall prepare a scientific paper describing the study, its purpose, methods, conclusions, etc. for submission to an appropriate refereed journal. Item 8 -- Presentation at MMS Information Transfer Meeting or Scientific Conference (Task 8): The Offeror shall present details of this study at the annual MMS Gulf of Mexico Information Transfer Meeting (ITM) or at another scientific conference, as agreed upon between the Offeror and MMS. Item 9 -- Bi-Monthly Progress Reports (Task 9): The Offeror shall submit bi-monthly, a concise report in letter format. Item 10 -- Presentation Slide Sets. (Task 10): The Offeror shall submit two identical sets of presentation slides with captions showing the model output for the various simulations. A coded, written description of each slide should accompany submittal. Item 11 -- Kickoff Meeting (Task 11): An initial meeting shall be held after the contract award in order to meet with the main personnel to be involved in the project (the Program Manager and all principle investigators) to review all project schedules and objectives and resolve any technical or managerial problems. The logistics involved and the plan for collecting relevant data will be discussed at this meeting. Item 12—Program Management and Control Requirements: The Offeror shall adhere to the Program Management Plan that was submitted to the MMS Contracting Officer (CO) and Contracting Officer's Technical Representative (COTR) in the RFP. Item 13 -- Data Management: The Offeror shall operate under a data management plan and system designed to ensure continuous evidence of data possession, comparison, and security with signatures, dates, times, and location of data being noted. HOW TO RESPOND: Interested parties will be must submit a request IN WRITING in order to receive a copy of the RFP. These requests may be faxed to the attention of Contracting Officer, Ms. J. Callas and the Procurement Assistant, Ms. L. Donley at (703) 787-1387.
