Deployment Protocol for the Placement of Rock on the Mattituck Reef

The rock shall not be deployed on the Mattituck Reef site before this Protocol has been reviewed, approved, and signed by the material owner or the designated Contractor responsible for the material preparation, transportation, and deployment.

The approved material must be prepared and placed on the designated target coordinates under the guidelines of this Protocol and the attached “New York State

Department of Environmental Conservation Marine Artificial Reefs Materials Preparation Criteria and Special Conditions” (Attachment 1). Should any other Criteria or Special Conditions be violated the DEC Reef Program may summarily suspend this deployment agreement with the material owner or their designee.

The attached map (Attachment 2) shows the location of the Mattituck Reef where the rock can be deployed. The accompanying table (Attachment 3) lists the site characteristics including corner boundary coordinates.

If any materials are deployed outside the designated reef site boundaries the Reef Coordinator must be notified immediately as such action constitutes a violation of the reef permits and corrective action must be taken.

Material deployment must be made under safe conditions (e.g., no excessive winds, currents, or seas) that will allow for accurate placement on the designated targets.

Side scan images have been used to determine material drop coordinates. Strict adherence to material deployment on the target coordinates provided (Attachment 4) will prevent interference with existing patch reefs and from deployments outside the designated reef boundaries. This Attachment also includes the minimum navigational depth clearance for the site.

The material will be inspected by DEC Reef Program staff, or their designee as required before they can be cleared for placement on the target coordinates provided.

The material should not be transported to the target coordinates unless conditions are suitable for deployment. If the materials are deployed on coordinates other than on or near the target provided in this protocol, the deployment time, deployment coordinates and depth measurement over the highest point of the materials deployed must be recorded and immediately reported to the Reef Coordinator as this may be a violation of the reef permit.

Materials must be towed to the predetermined reef site under guidelines detailed in the attached Towing Guidelines (Attachment 5). The updated Tow Plan for each individual deployment must be forwarded to the Reef Coordinator 24 to 48 hours prior to the deployment taking place.

The materials will be placed on a barge that can be anchored at the deployment coordinates provided or held in place by a vessel. When the barge is stationary on the designated deployment target, the time, GPS coordinates and a depth measurement will be taken where the materials are to be deployed and then recorded on the attached DEC Deployment Log (Attachment 6).

A buffer area should be maintained around the material barge for safety reasons and to prevent interference in the deployment process from non-project personnel.

After the GPS and depth measurements have been taken the deployment process may begin. Deployment can be completed by dropping the materials from a hopper barge, pushing the materials over the side of a barge using heavy equipment or by lowering to the sea floor by crane. The deployment method to be used must be discussed and cleared with the DEC Reef Program Coordinator prior to deployment.

After all materials have been successfully deployed on the designated target coordinates the deployment time, location in GPS coordinates and depth measurement over the highest part of the materials must be recorded on the attached DEC Deployment Log.

The depth measurement is of critical importance in determining if the permitted navigational control depth (Attachment 4) for the Mattituck Reef has been maintained. If the navigational control depth criteria has been violated the Reef Program Coordinator must be contacted immediately and informed of this condition because it is a major permit responsibility. The Owner and/or Contractor responsible for the material deployment will have a period of 10 days to ensure the navigational depth permit violation has been corrected and documented as per conditions of the attached U.S.

Army Corps of Engineers Reef Permit NAN-2020-00804 excerpt (Attachment 7).

The Reef Program Coordinator must be notified of the proposed material deployment date a minimum of 2 weeks in advance so the required permit notifications can be made. This can be done via e-mail (christopher.laporta@dec.ny.gov) or cell phone (XXX) XXX-XXXX. The deployment date confirmation must be made 48 hours prior to the materials being placed on the predetermined designated reef site target.

A completed Daily Reef Deployment Report, including a photograph of the material being deployed, must be submitted to the Reef Program Coordinator Chris LaPorta on or as close as possible to the day of the deployment by e-mail or mailed to the Division of Marine Resources Headquarters at 123 Kings Park Boulevard Nissequogue River State Park), Kings Park, New York.

The Reef Program Coordinator can also be contacted by phone at the office at (631) 444-0438, Monday through Friday, 8:30 AM to 5:00 PM.

Appl No.: n/a

Commenting Agency: NOAA Fisheries, Greater Atlantic Regional Fisheries Office (GARFO), Habitat and Ecosystem Services Division (HESD)

Action Agency Project Manager: Sophie Killy

Waterway: Lake Montauk

Activity: Maintenance dredge shoals in federal navigation channel with placement in nearshore (sand) and artificial reef (rock)

ESSENTIAL FISH HABITAT (EFH)

Project may adversely affect EFH.

ESSENTIAL FISH HABITAT CONSERVATION RECOMMENDATIONS: (Note: EFH CRs require a response from the federal action agency within 30 days of receipt or 10 days before a permit is issued if CRs are not included as a special condition of the permit. In addition, a distinct and further EFH consultation must be reinitiated pursuant to 50 CFR 600.920 (j) if new information becomes available, or if the project is revised in such a manner that affects the basis for the above EFH determination or EFH conservation recommendations.)

1. Continue to avoid dredging from January 1 to June 30 of each year to minimize adverse effects to winter flounder early life stages and their EFH (1/1 - 5/31) as well as migrating anadromous species including river herring (alewife Alosa pseudoharengus and blueback herring Alosa aestivalis) (3/1 - 6/30), which are prey for a number of federally managed species.

2. There is mapped submerged aquatic vegetation (SAV) on the east side of the inlet; SAV is a Habitat Area of Particular Concern for EFH. Should dredging need to occur during the SAV growing season of any given year, a visual survey should be conducted to document presence/absence of SAV within 500 feet of any area to be dredged. A minimum buffer between dredging area(s) and the edge of any SAV bed should be maintained between April 15 and October 15 of any year. The appropriate buffer is 250 feet if the sediments are 95% sand and 500 feet if less than 95% sand. Dredging can be sequenced to accommodate this buffer.

3. The intakes on the dredge plant should not be turned on until the dredge head is in the sediment and should be turned off before being lifted to minimize larval entrainment in the dredge.

4. Use BMPs to minimize the release of suspended sediments during sand placement activities.

FISH AND WILDLIFE COORDINATION ACT COMMENTS

COMPOSITE GRAIN SIZE DISTRIBUTION CURVES FOR SAND SEDIMENTS AND

GRAIN SIZE SCALES FOR SEDIMENT

The grade scale most commonly used for sediments is the Wentworth (1922) scale which is a logarithmic scale in that each grade limit is twice as large as the next smaller grade limit. The scale starting at 1mm and changing by a fixed ratio of 2 was introduced by J.A. Udden (1898), who also named the sand grades we use today.

However, Udden drew the gravel/sand border at 1 mm and used different terms in the gravel and mud division. For more detailed work, sieves have been constructed at intervals 2 ^(1/2) and 2^(1/14). The Φ (phi) scale, devised by Krumbein, is a much more convenient way of presenting data than if the values are expressed in millimeters, and is used almost entirely in recent work.

IV. MATERIALS AND METHODS

All sampling and testing were performed in accordance with Appendix B, Attachment 1 of the technical manual “The Management and Regulation of Dredging Activities and Dredged Material in New Jersey’s Tidal Waters” (NJDEP Dredging Manual), October 1997.

A. Sampling

Sediment was collected from seven locations in Lake Montauk Harbor by ASI personnel on April 26 and May 9, 2018.

The vessel used for sampling, the R/V Pompton, was positioned using a Trimble SPS 885 Differential Global Positioning System (DGPS). The project depth was 16 feet MLLW, including 2 foot. Sediment collection was performed using a Rossfelder P-3 vibracore with flexible plastic core liners.

The cores were inspected and photographed and the characteristics were recorded on Sediment Core Logs. All samples were assigned unique ASI sample numbers. All samples were received in good condition at ASI in Flemington, NJ and stored at 2-4 °C.

The appendices contain all supporting documentation including sediment core logs (Appendix A), photographs (Appendix B), chain of custody (Appendix C), sample use forms (Appendix D), grain size distribution raw data, calculations and graphs (Appendix E), and TOC raw data (Appendix F).

B. Homogenizing

Each of the core samples was carefully homogenized using a stainless steel mixer. This procedure followed the specific guidelines found on pages 9-11 and in Appendix A of the Dredging Manual and in ASI’s standard operating procedure SOP/PRP/008. Samples were mixed until uniform in color and texture. One composite was created from the samples. See Table 2 for the sample identification numbers and compositing scheme.

Sub-samples of each of the cores and the composite were reserved for grain size and TOC analyses.

C. Grain Size Distribution Analysis and Total Organic Carbon

Sub-samples of each sample were analyzed by ASI for grain size in accordance with the Standard Test Method for Particle-Size Analysis of Soils, Designation: D422-63 (Re-approved 2002). See Appendix E for the grain size raw data, calculations and distribution graphs.

Total Organic Carbon (TOC) was also determined based on the guidance from EPA Office of Solids Waste and Emergency Response SW-846 Method No. 9060 (Volume IC, Chapter 5, Revision 0, 9/86). The instrument for this analysis was the Dohrmann TOC Boat Sampler, Model 183 (Serial number 98202003), which was connected to the Dohrmann Apollo 9000 TOC Analyzer. See Appendix F for the TOC raw data and standard reference material control chart.

V. PHYSICAL ANALYSIS RESULTS

The results of the analyses for grain size distribution and total organic carbon for the sediment samples are provided in Table 3.

1.4.1.1 Payment

Payment will be made for costs associated with dredging of the project, which includes performing required dredging and other operations incidental thereto, placement area(s) and disposition of dredged material.

1.4.1.2 Measurement

The total amount of material removed and paid for under the contract will be measured by the cubic yard dredged. Measurement of the number of cubic yards in place will be made by computing the volume between the bottom surface shown by soundings of the last survey made before dredging and the bottom surface shown by soundings of a survey made as soon as practicable after the entire work specified has been completed. The volume for measurement shall include the material within the limits of the overdepth and side slopes.

The map and/or drawings accurately represent conditions existing on Jan 2025 in Lake Montauk Harbor, NY. The soundings shown on the contract drawings were collected using project classification soft as specified in EM-1110-2-1003 . Soundings after dredging will be made by an electronic depth recorder with a transducer frequency of 200 - 400 kHz or may be made using a multi-beam surveying system. After-dredging surveys will be completed generally within five days of completion of a section or the project. Determination of quantities removed to determine in-place quantities to be paid in the area specified, after having once made, will not be reopened, except on evidence of collusion, fraud, or obvious error.

Shoaling in the areas to be dredged is not at a rapid rate from existing depths. The unit price for dredging based on the above method of computation of the quantity for which payment is to be made shall include the Contractor's evaluation of shoaling, changes in the regimen of the waterway, or changes caused by the Contractor's operations that may occur during the period between the survey before dredging and the survey for acceptance of the work.

The Contractor must inform the Government, in writing, within three calendar days of completing the work.

The total quantity of excavated material for which payment will be made

SECTION 01 20 00 Page 2 will be the theoretical quantity between the ground surface as determined by a survey and the grade and slope of the theoretical cross sections indicated. No allowance will be made for the removal of any material outside the required grades and slope lines unless authorized.
