Peninsula, West Meadow Beach and Old Field Club), Towns of Brookhaven and
Smithtown, Suffolk County, New York
A detailed description and plans of the applicant's activity are enclosed to assist in your review.
The decision whether to issue a permit will be based on an evaluation of the probable impact
including cumulative impacts of the proposed activity on the public interest. That decision will reflect
the national concern for both protection and utilization of important resources. The benefit which
reasonably may be expected to accrue from the proposal must be balanced against its reasonably
foreseeable detriments. All factors which may be relevant to the proposal will be considered
including the cumulative effects thereof; among those are conservation, economics, aesthetics,
general environmental concerns, wetlands, historic properties, fish and wildlife values, flood
hazards, floodplain values, land use, navigation, shoreline erosion and accretion, recreation, water
supply and conservation, water quality, energy needs, safety, food and fiber production, mineral
needs, considerations of property ownership and, in general, the needs and welfare of the people.
The Corps of Engineers is soliciting comments from the public; Federal, state, and local agencies
and officials; Indian Tribes; and other interested parties in order to consider and evaluate the
impacts of this proposed activity. Any comments received will be considered by the Corps of
Engineers to determine whether to issue, modify, condition or deny a permit for this proposal. To
make this decision, comments are used to assess impacts on endangered species, historic
properties, water quality, general environmental effects, and the other public interest factors listed
above. Comments are used in preparation of an Environmental Assessment and/or an
Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments
CENAN-OP-RE PUBLIC NOTICE NO. NAN-2022-00176-EMI are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. ALL COMMENTS REGARDING THE PERMIT APPLICATION MUST BE PREPARED IN WRITING AND EMAILED TO REACH THIS OFFICE BEFORE THE EXPIRATION DATE OF THIS NOTICE, otherwise, it will be presumed that there are no objections to the activity. Comments submitted in response to this notice will be fully considered during the public interest review for this permit application. Comments provided will become part of the public record for this permit application. All written comments, including contact information, will be made a part of the administrative record, available to the public under the Freedom of Information Act. The Administrative Record, or portions thereof, may also be posted on a Corps of Engineers internet web site. Due to resource limitations, this office will normally not acknowledge the receipt of comments or respond to individual letters of comment. Any person may request, in writing, before this public notice expires, that a public hearing be held to collect information necessary to consider this application. Requests for public hearings shall state, with particularity, the reasons why a public hearing should be held. It should be noted that information submitted by email is considered just as carefully in the permit decision process and bears the same weight as that furnished at a public hearing. Our preliminary determination is that the activity for which authorization is sought herein is not likely to affect any Federally endangered or threatened species or their critical habitat. However, pursuant to Section 7 of the Endangered Species Act (16 U.S.C. 1531), the District Engineer is consulting with the appropriate Federal agency to determine the presence of and potential impacts to listed species in the project area or their critical habitat. The Magnuson-Stevens Fishery Conservation and Management Act, as amended by the Sustainable Fisheries Act (Public Law 104-267), requires all Federal agencies to consult with the National Oceanic and Atmospheric Administration Fisheries Service (NOAA/FS) on all actions, or proposed actions, permitted, funded, or undertaken by the agency, that may adversely affect Essential Fish Habitat (EFH). The proposed work, fully described in the attached work description, could cause the disruption of habitat for various lifestages of some EFH-designated species as a result of a temporary increase in turbidity during construction. However, the New York District has made the preliminary determination that the site-specific adverse effects are not likely to be substantial because it is expected that fish populations would avoid the small area of disturbance. Further consultation with NOAA/FS regarding EFH impacts and conservation recommendations is being conducted and will be concluded prior to the final decision. Based upon a review of the latest published version of the National Register of Historic Places, there are no known sites eligible for, or included in, the Register within the permit area. Presently unknown archeological, scientific, prehistorical, or historical data may be lost by work accomplished under the required permit. Reviews of activities pursuant to Section 404 of the Clean Water Act will include application of the guidelines promulgated by the Administrator, U.S. Environmental Protection Agency, under authority of Section 404 (b) of the Clean Water Act and the applicant will obtain a water quality certificate or waiver from the appropriate state agency in accordance with Section 401 of the Clean Water Act prior to a permit decision. This public notice serves as notification to the Administrator of the Environmental Protection Agency (EPA) pursuant to section 401(a)(2) of the Clean Water Act. If EPA determines that the proposed discharge may affect the quality of the waters of any state
CENAN-OP-RE
PUBLIC NOTICE NO. NAN-2022-00176-EMI
other than New York, it will so notify such other state, the district engineer, and the applicant. If
such notice or a request for supplemental information is not received within 30 days of issuance of
this public notice, the district engineer will assume EPA has made a negative determination with
respect to section 401(a)(2).
Pursuant to Section 307 (c) of the Coastal Zone Management Act of 1972 as amended [16 U.S.C.
1456 (c)], for activities under consideration that are located within the coastal zone of a state which
has a federally approved coastal zone management program, the applicant has certified in the
permit application that the activity complies with, and will be conducted in a manner that is consistent
with, the approved state coastal zone management program. By this public notice, we are
requesting the state's concurrence with, objection to, or waiver of the applicant's certification. No
permit decision will be made until one of these actions occur. For activities within the coastal zone
of New York State, the applicant's certification and accompanying information is available from the
Consistency Coordinator, New York State Department of State, Division of Coastal Resources and
Waterfront Revitalization, Coastal Zone Management Program, One Commerce Plaza, 99
Washington Avenue, Albany, New York 12231, Telephone (518) 474-6000. Comments regarding
the applicant's certification, and copies of any letters to this office commenting upon this proposal,
should be so addressed.
In addition to any required water quality certificate and coastal zone management program
concurrence, the applicant has obtained or requested the following governmental authorization for
the activity under consideration:
• New York State Department of Environmental Conservation
It is requested that you communicate the foregoing information concerning the activity to any
persons known by you to be interested and who did not receive a copy of this notice. Please send
all comments and questions concerning this application to Christopher.W.Minck@usace.army.mil.

WORK DESCRIPTION
The permit applicant, Suffolk County Department of Public Works (SCDPW), has requested
Department of the Army (DA) authorization to conduct dredging, with ten-years maintenance with
placement of all resultant dredged material at two designated beach placement areas. The project
is located at Stony Brook Harbor, in the Towns of Brookhaven and Smithtown, Suffolk County, New
York.
The proposed work would involve the following:
Maintenance dredge with ten-years maintenance, by hydraulic dredge, approximately 50,000
cubic yards (CY) of material from an approximately 960,935 square foot (22.06 acres) channel
system to a depth of five or seven feet below the plane of Mean Low Water (MLW). The
approximate slope of the channel system would be 1 to 3. The dredged material would be placed
at two designated beach placement areas along the Smithtown Bay shoreline to the northeast of
the channel (West Meadow Beach and Old Field Club) and west of the channel (Long Beach
Peninsula) via a dredge pipeline.
The channel system consists of the following:
• Yacht Club Spur: Dredge approximately 25,000 CY of material from an approximately 100-
foot-wide by 2,400-foot-long channel to a depth of seven feet below the plane of MLW.
• Porpoise Channel: Dredge approximately 6,000 CY of material from an approximately
100-foot-wide by 5,200-foot-long channel to a depth of seven feet below the plane of MLW.
• Porpoise Channel Spur: Dredge approximately 9,000 CY of material from an
approximately 100-foot-wide by 1,200-foot-long channel to a depth of seven feet below
the plane of MLW.
• Youngs Island: Dredge approximately 10,000 CY of material from an approximately 375-
foot-wide by 500-foot-long triangular area to a depth of five feet below the plane of MLW.
The approximately 50,000 CY of material would be placed at either of the two beach nourishment
areas, or a combination of both after each dredge event. The volumes and areas below assume
the full volume of material will go to one location per dredging event:
• Long Beach Peninsula (Western Area): Approximately 18,700 CY of the total 50,000 CY
of dredged material will be placed below the plane of SHW over 240,000 square feet (5.51
acres). The remaining 31,300 CY would be placed landward of the plane of SHW.
• West Meadow Beach and Old Field Club (Northeastern Area): Approximately 12,900 CY
of the total 50,000 CY of dredged material will be placed below the plane of SHW over
199,500 square feet (4.58 acres). The remaining 37,100 CY would be placed landward of
the plane of SHW.
The applicant plans to conduct three (3) additional dredging events within the ten-year
maintenance dredging period removing a maximum of approximately 50,000 CY per event from
within the same dredging area with beach placement at the above referenced areas.
The applicant has stated that they have avoided, minimized, and mitigated for potential impacts
proposed to the maximum extent practicable by limiting the dredged area to the minimum area
required for safe and reasonable navigation of Stony Brook Harbor. Any potential impacts would
be temporary and would be offset by implementing best management practices associated with
CENAN-OP-RE PUBLIC NOTICE NO. NAN-2022-00176-EMI the proposed use of a hydraulic dredge and floating pipeline. The use of a hydraulic dredge and floating pipeline would provide the cleanest and least obtrusive method for sediment removal and transport, minimizing to the greatest extent possible any potential adverse effects to the aquatic environment. The stated purpose of this project is to maintain safe navigable depths for vessel use in the waterway.
