The Atlantic Harbor of Refuge, authorized under Section 107 of the River and Harbor Act of 1960, was constructed in 1972. It is in the mainland unincorporated community of Atlantic and situated off Core Sound 3 miles west of Ophelia Inlet. Figure 1 shows the Atlantic Harbor vicinity in plan view. The harbor is important to the local fishing industry as a place of safety, and access to the Atlantic Ocean. As such, the harbor facilitates a vital component contributing towards the continued longevity of the local community. CARTERET COUNTY, NC Atlantic Harbor Sea Ophene Lew' Inlet Atlantic Bmofnn Ocean 'Na ri Figure 1. Atlantic Harbor Vicinity Map (NTS) The Atlantic Harbor of Refuge is a federally -authorized project that has been historically maintained by the USACE; however, the USACE has experienced difficulty in dredging the harbor recently due to the lack of an upland material placement facility. The Wilmington District (SAW) notified Carteret County of the maintenance difficulties in June of 2017 and requested the County take actions to construct a placement facility and potentially dredge the harbor'. In response to the USACE's notification, Carteret County has secured a material placement facility and intends to maintenance dredge the inner harbor of refuge and entrance channel. The maintenance work will remove approximately 13,200 cubic yards (CY) of silty material from the proposed work areas as shown in Appendix D (permit drawings). The maintenance work maintains consistency with the federal authorization for Atlantic Harbor and provides a maximum 40-ft channel at elevation -6-ft MLLW +1 through the harbor entrance. The template also maintains a 51-1:1 V sideslope to discourage additional sediment sloughing from the adjacent area. Within the harbor entrance, the side slopes increase to a 31-1:1 V to minimize the dredging footprint. The proposed channel width and depth also reduces within the harbor entrance to a minimum width of 16-ft at elevation -5-ft MLLW +1. Inside the harbor, the maintenance template maximizes the dredging potential by expanding to approximately 190-ft wide with ' Medlock, J. (2017, June 29) Letter to County Manager. USACE. Wilmington Districts. RECEIVED APR 01 2019 DCM-MHD CITY Carteret County Navigation Project Maintenance Dredging of Atlantic Harbor Permit Narrative (March 2019) 5H:1 V side slopes. However, the template maintains the maximum dredge depth of -5-ft MLLW +1 as proposed for the entrance channel. Appendix D (permit drawings) provides additional details describing the maintenance template. An emergency maintenance dredging project along the entrance of Atlantic Harbor was permitted (GP# 71340) and conducted in the summer of 2018 to provide short-term relief of the shoaling impacts. This maintenance dredging project removed approximately 1,000 cubic yards (CY) to create a narrow channel through a heavily shoaled area immediately outside of the harbor entrance. However, the County now intends to conduct a more extensive maintenance operation to provide a long-term solution for the local navigation needs. The navigation channel is authorized for a width of 75 feet at elevation -7-ft MLLW with 3H:1 V side slopes. However, a recent hydrographic survey conducted by Carteret County shows elevations outside the harbor entrance of -2 to -4 feet MLLW. Inside the harbor, elevations range between -4-ft and d-ft MLLW. Therefore, the County is proposing maintenance dredging to restore navigational access and preserve the harbor of refuge status. Appendix A (permit drawings) shows the existing contours representing the referenced hydrographic survey, along with cross -sections with existing and proposed depths identified. Sediment Compatibility To support development of a dredging plan and associated permitting, sediment cores from Atlantic Harbor were collected and tested in March 2018 (Appendix E). Based on review of the analysis for geotechnical vibracore samples the dredge material is considered not beach compatible and will be placed in an upland placement facility on nearby White Point. In addition to geotechnical analysis, five sites were sampled for chemical analysis beginning inside the harbor entrance and extending southwest along the existing channel (Appendix F). Chemical analysis on the core composites was conducted in accordance with the USACE guidance, Sediment Testing Guidelines for Dredged Material Proposed for Disposal in Federal Project Disposal Areas by Applicants, along with other screening guidelines. The results of the chemical analysis were used to develop a risk assessment (Appendix G). Results of the analysis showed some parameters greater than selected screening levels. These included concentrations of certain metals, semi -volatile organic compounds, and pesticides within the harbor and near the entrance. Additional testing outside of the harbor showed decreased levels of these same contaminants. Semi volatile organic data for these stations were primarily non -detect or below the reporting limit and there were no exceedances of the screening levels. For metals outside the harbor, there were limited elevated concentrations (i.e., total chromium and manganese). Since there were some elevated concentrations of certain contaminants based on the screening analysis, further analysis of the cumulative effects of multiple contaminants was conducted using a risk calculator developed by the Division of Waste Management (DWM). Designed to evaluate multiple exposure routes associated with contaminated environmental media, the calculator estimates the risks associated with current or potential future human exposure. The risk calculator was populated with sediment core data from three sites representing the areas to be dredged and in consultation with DWM staff2. Application of the risk tool showed potential risk associated with arsenic and chromium for all three sites with the addition of thallium for one site. However, the cumulative risks under the User Defined receptor 2 Robbins, S. (2018, October 4) Phone call to 910-796-7217. RECEIVED APR 01 2019 DCM-MHD CITY Carteret County Navigation Project Maintenance Dredging of Atlantic Harbor Permit Narrative (March 2019) covering periodic use for a recreator and a trespasser do not exceed the benchmark assumptions in the tool. Further, chemicals like arsenic, chromium, and thallium have natural and common anthropogenic sources that are likely influencing the results at these stations. The Resident receptor is not applicable in these cases because, the dredge disposal site, White Point, does not have residential development. In addition, Carteret County intends to file a deed stipulation disallowing any future residential development on the property. A copy of the recorded deed restriction shall be provided to DCM prior to the commencement of the dredging activities. In summary, the results demonstrate that disposal of the dredge material on White Point does not pose a significant risk to human health or water quality. Construction Methodology and Sediment Placement Approximately 13,200 CY of dredge spoil will be directly placed in a Carteret County -owned site adjacent to the work area referred to as "White Point' and shown on Figure 2. Dredging operations will be conducted by a bucket dredge/excavator between November 16 and March 31 in efforts to minimize the potential for environmental impacts. Dredging activities will extend through day light hours but will not entail night time operations. Material will be dredged from the Atlantic Harbor channel and placed on a barge or other floating work plant. A turbidity control barrier will be utilized and remain until sediment in the water column has settled. The material will be transported to the disposal site on White Point. A backhoe or excavator will move the material from the barge to a truck or other hauling equipment on White Point where it will be placed and contained within an earthen berm. The County has provided a letter verifying ownership of White Point as well as secured an easement for construction equipment access (Appendix H). All dredge spoil will be placed a minimum of 30-ft landward from MHW. Figure 2. Material Disposal Site (White Point) The dredged material will be dewatered and placed within the upland disposal site with the intent of permanent storage. Earthen berths will be used to prohibit the effluent waters from reentering the adjacent RECEIVED APR 01 2019 OCM-MHD CITY Carteret County Navigation Project Maintenance Dredging of Atlantic Harbor Permit Narrative (March 2019) water bodies. In addition, turbidity curtains will be maintained surrounding the offloading site during times of dredging activities. The curtains will be positioned to capture any sediment disposition spilling from the construction process. Prior to placement of dredge spoils, the spoil containment basin and berms will be inspected to ensure the effectiveness and capacity to contain the material. The Division of Coastal Management (DCM) will be notified so a representative may inspect the site to help verify the appropriate BMPs have been established to help control the dredge effluent and material run-off. In addition, DCM will be notified immediately in the unlikely event of containment breech. Environmental Concerns Based on meetings with regulatory agencies in December 2017 and 2018, the anticipated major regulatory requirements include 408 Review through the USACE Civil Works branch, a Coastal Area Management Act (CAMA) major permit, and USACE General Permit (GP) 2878. The GP 2878 is issued by the USACE Wilmington District "to authorize maintenance dredging within federally authorized navigation channels and borrow areas, and the discharges of excavated and/or fill material within federally approved confined upland disposal areas or, in the case of beach quality sand, federally authorized beach retention areas or federally authorized beach nourishment project areas in the state of North Carolina." Additional input from resource agencies indicated no Biological Assessment for protected species nor a SAV survey would be required. Other requirements include chemical testing of dredge material following DWM guidelines due to the nature of expected dredged material (i.e., muddy). Water flow from dewatering of dredged material will be directed towards the inner harbor to avoid impacts to shellfish in Core Sound. Dredging activities will be restricted to November 16 through March 31 for additional protection towards potential impacts. The cooler months generally offer a lower risk for environmental impact. Historic Resources An archaeological assessment has not been completed for the proposed dredging; however, the site is a federally authorized navigation channel and has been dredged since the 1940's. North Carolina Environmental Policy Act (SEPA) The project involves expenditure of public funds and is in compliance with the North Carolina Environmental Policy Act (SEPA). SEPA applies for any project that meets all three of the following criteria, an environmental document must be prepared: 1. An expenditure of $10 million in funds provided by the state of North Carolina for a single project or action or related group of projects or action Or land -disturbing activity of equal to or greater than 10 acres of public lands resulting in substantial, permanent changes in the natural cover or topography of those lands (or waters) 2. An action by a state agency, and 3. Has a potential detrimental environmental effect upon natural resources, public health and safety, natural beauty, or historical or cultural elements, of the state's common inheritance. RECEIVED APR 01 2019 DCM-MHD CITY Carteret County Navigation Project Maintenance Dredging of Atlantic Harbor Permit Narrative (March 2019) Since the project is less than $10 million and disturbs less than 10 acres of public land, further environmental documentation under SEPA is not required. In addition, under 15A NCAC O1C .0408, this project does not meet minimum criteria associated with development requiring a Coastal Area Management Act (CAMA) permit or a State Dredge and Fill Law permit because it involves "maintenance activities associated with maintaining the traditional and established use of a channel." Summary In summary, the County is requesting state and federal authorization to conduct maintenance dredging of Atlantic Harbor to aid navigation and preserve the health and safety of boaters traversing in and out of the harbor. A total of approximately 13,200 CY will be dredged and placed on County -owned White Point, which was also the material placement location for the previously conducted emergency project. The proposed maintenance dredging will restore the channel to depths in the inner and outer harbor to -5-ft MLLW +1 to -6-ft MLLW +1 inclusive of a 1-ft overdredge tolerance. Sediment analysis confirmed the material is not beach compatible and that the chemical quality was such that placement on White Point with no residential uses was appropriate and did not present a significant risk to the public. The proposed work will follow additional guidelines and recommendations to avoid or further minimize the potential for environmental impacts during construction. This includes constructing during the cooler winter months of November through March, as well as the use of turbidity curtains, a containment berm, and silt fence.

Artemis was equipped with all required United States Coast Guard (USCG) safety gear and was operated by a USCG -certified 100 Ton Master Captain. A Trimble Differential Global Positioning System (capable of sub -meter accuracy) interfaced with HYPACK was utilized for primary navigation. Horizontal coordinates were recorded in North American Datum of 1983 State Plane Coordinate System, North Carolina (Zone 3200), U.S. Survey Feet. Real-time tide elevation data were obtained using a Champion TKO Global Navigation Satellite System (GNSS) receiver interfaced with the North Carolina Continuously Operating Reference Station Network, which served as the base station. l _ >A73-. Figure 2: Research vessel Artemis offshore of Mobile Bay, Alabama. During field operations, Artemis was immobilized over the desired sample sites using spuds. Once on station, the coordinates at the vessel location were compared with the coordinates for the desired sample location to ensure accurate vessel positioning. A vibracore location map has been included as Figure 3. Upon satisfactory positioning, a water depth was collected via lead line. Subsequently, the tide elevation was recorded in North American Vertical Datum of 1988 (NAVD 88) at each sample location and was converted to MLLW using the National Oceanic and Atmospheric Administration's Vertical Datum Transformation (VDatum) software program (Version 3.6.1). The converted data, in conjunction with the recorded water depth, were then used to determine the sediment surface elevation in relation to MLLW at each sample location. Vertical (and horizontal) data conversions are summarized in Table 1.

The vibracore system consists of a generator with a mechanical vibrator attached via cable to a 3-inch diameter, galvanized sample barrel. The sample barrel was lowered until the bottom of the barrel was directly above the sediment surface. The vibracore machine was turned on and the sample barrel was allowed to penetrate until the bottom of the sample barrel reached project depth. Once the sample barrel reached project depth, the machine was turned off and the sample barrel was retrieved using an electric winch. The cores were then capped, labeled, and cut into 5-foot sections. A summary table containing final location coordinates, elevation data, and penetration and recovery lengths has been included as Table 2. The completed cores were opened longitudinally at Athena's core processing facility in McClellanville, South Carolina. The cores were photographed after opening and were logged in accordance with protocol outlined in ASTM D 2488 and ASTM D 2487. One composite sample was collected to a depth of -11.5' MLLW from each core. Furthermore, discrete samples were collected from targeted sediment intervals in each core. The composite and discrete samples were submitted to Terracon Consultants, Inc. (Terracon) in Jacksonville, Florida, for analysis. Terracon is a USACE-accredited geotechnical laboratory. All samples were analyzed for grain size distribution in accordance with ASTM D 6913 using the following sieve sizes: 3/4", 5/8", 7/16", 5/16", No. 3.5, No. 4, No. 5, No 7, No. 10, No.14, No. 18, No. 25, No. 35, No. 45, No. 60, No. 80, No. 120, No. 170, No. 200, and No. 230. The laboratory also conducted visual percent shell determination for each sample using the Terry and Chilingar method (1955). The composite samples were analyzed for carbonate content in accordance with the Twenhofel and Tyler acid digestion method (1941). A summary of laboratory results is presented in Table 3. Core photographs and logs have been included as Appendix A, and laboratory analytical reports have been included as Appendix B.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round -off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 03/28/2018 and 03/28/2018; the samples arrived in good condition, properly preserved and on ice. The temperatures of the 3 coolers at receipt time were 3.40 C, 4.80 C and 5.80 C. The following samples were listed on the Chain of Custody (COC); however, no samples were received as there was a cooler delayed in shipment. These samples were received on March 29, 2018 within temperature: AH-07-0318-Gl (180-76196-1). AH-07-0318-G2 (180-76196-2), AH-07-0318-G3 (180-76196-3), AH-07-0318-C (180-76196-4) and AH-06-0318-Gl (180-76196-5). The container label for the following sample did not match the information listed on the Chain -of -Custody (COC): AH-04-0318-G3 If 80-76196-15). The container labels list AH-04-0318-G2, while the COC lists AH-04-0318-G3. The id on the COC was used. The Chain -of -Custody (COC) was incomplete as received and/or improperly completed. The COC lists three containers for the following sample; however two were received. The vials received for the TOC analysis were preserved at the laboratory per the notation on the COC: EB-02-0318 (180-76196-24) The following samples were received outside of the holding time for freezing the volatile terracores. The terra core vials were frozen as soon as possible after receipt. The samples have had the H qualifier applied: AH-07-0318-Gl (180-76196-1), AH-07-0318-G2 (180-76196-2), AH-07-0318-G3 (180-76196-3) and AH-07-0318-C It 80-76196-4). VOLATILES Methylene Chloride was detected in method blank MB 180-24089617 at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. Methylene Chloride was detected in method blank MB 180-241049/6 at a level that was above the method detection limit but below the reporting limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. The following analyte recovered outside control limits for the LCS associated with analytical batch 180-240736: Chloroethane. This is not indicative of a systematic control problem because these were random marginal exceedances. Qualified results have been reported. The continuing calibration verification (CCV) associated with batch 180-240660 recovered above the upper control limit for Dichlorodifluoro-methane. The samples associated with this CCV were non -detects for the affected analytes; therefore, the data have TestAmerica Pittsburgh Page 3 of 106 4/18/2098 Case Narrative Client: Athena Technologies, Inc Project/Site: North Carolina Sediment Project Job ID: 180-76196-1 (Continued) Laboratory: TestAmerica Pinsburgh (Continued) been reported. The following sample is impacted: (CCVIS 180-240660/2). TestAmerica Job ID: 180-76196-1 The continuing calibration verification (CCV) associated with batch 180-240865 recovered above the upper control limit for Carbon Tetrachloride. The samples associated with this CCV were non -detects for the affected analytes; therefore, the data have been reported The following sample is impacted: (CCVIS 180-240865/2). SEMIVOLATILES An incorrect volume of surrogate spiking solution was inadvertently added the following samples: AH-02-0318-C (180-76196-12). Percent recoveries are based on the amount spiked. The following samples were diluted due to the nature of the sample matrix: AH-07-0318-C (180-76196-4), AH-06-0318-C (180-76196-8), AH-02-0318-C (180-76196-12), AH-04-0318-C (180-76196-16), AH-05-0318-C (180-76196-21), AH-05-0318-C-DUP (180-76196-22), (180-76196-A4-B MS) and (180-76196-A4-C MSD). Elevated reporting limits (RLs) are provided. The continuing calibration verification (CCV) analyzed in batch 180-241401 was outside the method criteria for the following analyte: Nitrobenzene-d5 (Surr) was >20% high. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte is considered estimated. PESTICIDES The following samples were diluted due to the nature of the sample matrix: AH-02-0318-C (180-76196-12), AH-04-0318-C (180-76196-16), AH-05-0318-C (180-76196-21) and AH-05-0318-C-DUP (180-76196-22). Elevated reporting limits (RLs) are provided. The sample extracts were a medium yellow color after GPC clean-up. Surrogate DCB Decachlorobiphenyl (Surr) recovery for the following sample was outside control limits on the confirmation column: EB-02-0318 (180-76196-24). Evidence of matrix interference is present due to preceding sample analyzed; therefore, re -extraction and/or re -analysis was not performed. Surrogate recovery was outside acceptance limits for the following sample: (180-76196-A-8-1 MSD). The parent sample and MS surrogates recovery was within limits. The MSD sample has been qualified and reported. Several analytes failed the recovery criteria low for the MS/MSD of sample AH-06-0318-C (180-76196-8) in batch 180-242257. The continuing calibration verification (CCV) associated with batch 242257 recovered outside acceptance criteria, low biased, for delta-BHC and Endosulfan sulfate. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non -detect for this analyte, the data have been reported. The continuing calibration verification (CCV) associated with batch 241080 recovered outside acceptance criteria, low biased, for delta-BHC and Endosulfan sulfate on MR-1 column and Endosulfan sulfate and Endrin ketone on MR-2 column. A reporting limit (RL) standard was analyzed, and the target analyte was detected. Since the associated samples were non -detect for this analyte, the data have been reported. Detections of these compounds were taken from their passing column, where applicable. METALS No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GENERAL CHEMSITRY The sample post -digestion spike (PDS) recoveries were outside criteria. Acceptable laboratory control sample (LCS) soluble and insoluble analysis data demonstrate that the analytical system was operating in control; therefore, this condition is most likely due to a matrix effect. The reporting limit for Lloyd Kahn TOC analysis is a nominal value and does not reflect adjustments in sample mass processed on an individual basis.
