The proposed project would place approximately 258,000 c .y. of sand between R-3 . 5 and R- 17 (approximately 12,900 feet) . The project would utilize two borrow areas — an offshore borrow area and the Sebastian Inlet Sand Trap. Three borrow sites have been permitted for this project — two offshore borrow areas and the Sebastian Inlet Sand Trap. The offshore borrow areas are designated as a Primary Borrow Area (previously permitted under the Sector 7 project) and a Secondary Borrow Area. The Primary and Secondary Borrow Areas are adjacent to one another, and are located approximately 15 nautical miles south of the south project fill limit, and is located within the Indian River Shoal complex. The borrow area resides between 7 ,000 and 10,000 ft offshore of the southern part of Indian River County, just north and directly offshore from Round Island Park (R- 118) , in the Atlantic Ocean. Dredging of the borrow area shall not exceed the lines and grades as specified in the contract Drawings and Documents for the project. The Primary and Secondary Borrow Areas are shown in Figures Ithough 4 . The Sebastian Inlet Sand Trap is located within the Sebastian Inlet, and was designed to trap sand during the flood tide. Approximately 105 ,000 c .y. of beach compatible sand will be dredged from the sand trap. The sand from the sand trap will be dredged and placed along the northern end of the project. The dredge disposal will be carefully monitored for material that is not compliant with Florida Statues. Figures 5 and 6 depict the sand trap and designed dredge cuts . This combined Borrow Area Sediment Quality Assurance/Quality Control Plan, as required by Rule 62B-41 .008( 1 ) (k)4 .b . , F.A.C . and Permit 0166929-010-EM Specific Condition Numbers 8 and 10(b), is written with the intent of: • Providing project-specific sediment quality specifications for the grain size distribution, color, and carbonate composition to ensure the sediment from the borrow area will meet the standard as set forth by Rule 6213-41 . 007(2)(j), F .A. C . ; • Furnishing quality control procedures for excavating sediment within the authorized horizontal and vertical limits of the permitted borrow area; • Supplying procedures for the monitoring and reporting of the quality of sediment as it is placed on the beach and following placement; • Identifying methods for altering or stopping construction and dredging operations if the sediment does not comply with the project specific sediment quality specifications; and 1 DEP Permit No . : 0166929 -010-EM • Detailing methods for remediation of any areas where fill material does not comply with the sediment quality specifications. The specific Borrow Area Sediment Quality Assurance Plan and the Borrow Area Sediment Quality Control Plan for the Indian River County Sectors 1 &2 Beach Renourishment Project follow. The County and the Engineer will enforce the relevant Terms and Conditions of the Contract Documents and the related permits throughout the construction process. The Contractor shall be required to comply with all Terms and Conditions of the Contract Documents and the related permits and shall comply with the Quality Assurance Plan as detailed herein. The Quality Assurance Plan to be implemented by the Contractor shall be discussed at the Pre-Construction meeting. The Contractor shall submit a written acknowledgement of agreement with the Plan as written and/or as amended per discussion and mutual agreement of the amended Plan by the County and the Contractor. Sediment Ouality Rule 62B-41 .007(2)0 ) , F .A. C . states: "To protect the environmental functions of Florida 's beaches, only beach compatible fill shall be placed on the beach or in any associated dune system. Beach compatible fill is material that maintains the general character and functionality of the material occurring on the beach and in the adjacent dune and coastal system. Such material shall be predominately of carbonate, quartz or similar material with a particle size distribution ranging between 0. 062mm (4. 04 phi) and 4. 76mm (-2. 254 phi) (classified as sand by either the Unified Soils or the Wentworth classification), shall be similar in color and grain size distribution (sand grain frequency, mean and median grain size and sorting coefficient) to the material in the existing coastal system at the disposal site and shall not contain: 1 . Greater than 5 percent, by weight, silt, clay or colloids passing the #230 sieve (4. 04 phi); 2. Greater than 5 percent, by weight, fine gravel retained on the #4 sieve (-2. 254 phi); 3. Coarse gravel, cobbles or material retained on the 3/4 inch sieve in a percentage or size greater than found on the native beach; 4. Construction debris, toxic material or other foreign matter; and 5. Not result in cementation of the beach. If rocks or other non-specified materials appear on the surface of the filled beach in excess of 50% of background in any 10, 000 square foot area, then surface rock should be removed from those areas. These areas shall also be tested for subsurface rock percentage and remediated as required. If the natural beach exceeds any of the limiting 2 DEP Permit No . : 0166929-010-EM parameters listed above, then the fill material shall not exceed the naturally occurring level for that parameter. " The provisions of this rule shall be adhered to by the Contractor and enforced by the engineer and the County throughout the construction process . In addition to the provisions delineated within Rule 62B-41 .007(2)0) F .A.C . the placed material will conform to the physical parameters specified within Table 1 . Table 1 Placed Material Project Characteristics Minimum Requirements Characteristic Range Mean Grain Size 0.25 to 0 .65 mm Carbonate Content Not to Exceed 80% Moist Color (Munsell) l OYR/6 or lighter Sediment Excavation In order to achieve the sediment quality requirements as outlined herein, a specific borrow area cut geometry for both the offshore and Sebastian Inlet Sand Trap sites was developed based on extensive field evaluations and detailed geotechnical analysis. The results of these analyses are identified in the Contract Documents (Plans and Specifications) . The borrow area geometry as identified in the figures shows the limits of the borrow area. Additionally, a magnetometer survey has identified anomalies within the borrow area and a dredge exclusion area is represented in Figures 1 and 3 . The dredge shall not operate within the identified Dredge Exclusion Area. The elevations (depths) of the cuts within the Primary and Secondary Borrow Areas are -31 feet NGVD and -30 feet NGVD , respectively and as identified in Figures 2 and 4; this depth includes a -2 foot overcut allowance. The Sebastian Inlet Sand Trap and its cut geometries are shown in Figures 5 and 6 . The borrow area has multiple cut geometries, which will reduce the potential of encountering rock. The depth of the cuts vary from - 11 feet NGVD to - 16 feet NGVD . The Contractor shall not excavate material from outside the horizontal or vertical dredge delineations. Testing of Fill Material The Site Representative shall collect samples of the beach fill material placed along the project shoreline to ensure the material being placed by the Contractor is within the project specifications and adheres to the material quality standards as outlined by Rule 6213-41 . 007(2)(j), F.A.C. Testing shall consist of visual observations and samples to be analyzed through standard laboratory procedures. 3 DEP Permit No. : 0166929-010-EM Shore-normal transects (bearing North 70° East) shall be established along the project area. The transects shall be spaced approximately 500 feet apart along the length of the beach fill placement (Project) area (at previously-established '/2 stations) . Every second transect line shall be coincident with DEP Reference Monuments (R-4 through R- 17 , inclusive) in the Project area. Sediment samples shall be collected according to the following procedure: Following the completion of an acceptance section, two (2) test holes a minimum of 18 inches deep shall be excavated along each shore normal transect, within the limits of the constructed berm . The test holes shall be evenly spaced across the beach profile within the predicted equilibrium beach berm. From the test hole excavated sediments, the material shall be mixed in a container (bucket or similar) to a homogeneous consistency. Two replicate sediment samples (a minimum of 250 grams per sample) shall be collected at each test hole. One of the sediment samples collected at each test hole shall be sent for laboratory analysis while the other sample shall be archived. The laboratory analysis shall consist of a grain size distribution analysis and the determination of the percent carbonate/quartz present within the samples. The material will be tested in accordance with American Society for Testing Material (ASTM) standards, and the data will be provided to the Department in gfNTr' format. The grain size will be tested in accordance to ASTM Standard D-422 for mechanical analysis of soils methods, and textural classification will be performed in accordance to the Unified Soils Classification System as described by ASTM Standard D-2487. The archived samples and laboratory data shall be submitted to the FDEP upon project completion. The fine/silt content will be determined by both the Wentworth and ASTM (Standard D- 1140) methods. For the Wentworth method, the material will be washed through a #230 sieve (0 .062 mm) opening, and the material that passes is the silt/fine fraction. The remaining material is dried and mechanically sieved through a stack of sieves in half phi sizes over a range from -2 phi to 4 phi including the #230 wive. The fine/silt fraction based on the ASTM method is determined by the amount of material retained by the #200 and #230 sieves. The sample gradation is based on the result of the dry sieving process. The carbonate fraction of the sample is determined by a high temperature burnt . A pre- weighed sample is burned (or ignited) at a temperature of 1080° for a time of 8 hours . This process changes the chemical composition of the sample, and the carbonate fraction is determined by weighing the sample and applying the atomic weights of the elements forming the carbonate crystal lattice. Pre-construction sampling will be conducted at every even numbered DEP Reference Monument following the procedures delineated herein for the post construction monitoring.

Sedimentary Petrology, V. 44, 242-248 . 4 DEP Permit No. : 0166929-010-EM Construction observation will occur daily by the County or the County' s representative throughout the duration of sand placement operations by the Contractor. Observations will be made at least once per hour during placement activity of the material at the discharge location. A sample of the dredge discharge will be collected, and a qualitative assessment of the sand color (moist) and grain size will be noted. The location of the discharge pipe (relative to the DEP Reference Monument), date and time of the sample, borrow area and qualitative sand color (moist) will be noted on the sample bag. Observations will be made of the Contractors ' work to assure the work is in conformance with the required contract and permit conditions. An individual with training or experience in beach nourishment and construction inspection and testing (Site Representative) will perform the daily review. That person shall be knowledgeable of the project design and the contract and permit conditions . The Project Engineer, a qualified coastal engineer, shall actively manage the individual performing the daily inspections. Communications shall take place on a daily basis between the Project Engineer and the Site Representative. The Project Engineer and/or Site Representative shall be continuously on call during the construction period in order to make decisions regarding issues that involve the Quality Assurance and Quality Control Plans. The Contractor shall provide daily reports to the County detailing the material quality and quantity being excavated from the borrow area. The report will include the location of the dredge within the borrow area, the depth of cut, the volume of material being excavated, and an assessment of the material quality being excavated including an estimation of the daily intake of shell hash. In the event of the occurrence of rock or large amounts of clay, the volume of material shall be quantified and reported and the Quality Control Plan measures initiated. Additionally, the daily report shall identify the location, approximate moist color and quality of the material being placed along the beach. The reports will be provided to FDEP following the completion of the project or at any time so requested by FDEP staff. Any addendum or change order to the Contract between the County and the Contractor shall determine whether or not the change in scope will potentially affect the Quality Assurance and Quality Control Plans. Remediation If the sampled material, as outlined in the Testing of Fill Material section of this Plan, does not meet the material quality standards as outlined by Rule 6213-41 .007(2) (j), F .A.C . this shall be reported to the County and the FDEP to determine if remediation is necessary . If remediation is necessary it shall be conducted prior to the marine turtle nesting season following the completion of the beach fill project. Remediation may include tilling or blending unacceptable beach fill material with adjacent material or moving the unacceptable material seaward of the mean high water line, subject to approval by the FDEP . Re-sampling shall be conducted following any remediation effort and results reported to the FDEP and the County as described in the Testing of Fill Material section of this Quality Assurance Plan. 5 DEP Permit No . : 0166929-010-EM If the material sampled on an hourly basis, as outlined in the Monitoring and Reporting section of this Plan, does not appear to meet the material quality standards as outlined by Rule 6213-410007(2)(j) , F .A.C . , the Site Representative will immediately notify the Project Engineer. The dredge will be directed to an area of clean sand, and the noncompliant material will be placed seaward of the constructed MLW waterline. The DEP will be notified of the time and amount of dredged material that was found to be noncompliant, as well of the corrective actions exercised by the Site Representative and Project Engineer. 6 DEP Permit No. : 0166929-010-EM Indian River County, Florida Shore Protection Project - Sectors 1 and 2 Borrow Area Sediment Quality Control Plan The County and the Engineer will enforce the relevant Terms and Conditions of the Contract Documents and the related permits throughout the construction process. The Contractor shall be required to comply with all Terms and Conditions of the Contract Documents and the related permits and shall comply with the Quality Control Plan as detailed herein. The County's Site Representative shall communicate daily (or on an event basis as needed) with the Contractors designated and responsible Site Representative the results of the sediment quality testing. Should sediment characteristics on the beach fill section in progress dictate corrective action, the Contractor's designated representative shall have the authority to alter dredge operations and/or beach fill placement grading to ensure compliance with the provision of the issued permit and this document. The Quality Control Plan for the borrow area has the purpose of ensuring that sediment from the permitted borrow area meets the material quality standards as outlined by Rule 62B-41 . 007(2)0), F.A.C. and specifically that the Contractor stay within the borrow area limits as outlined in the Permit and in the Contract Plans and Specifications. Sediment Excavation In order to achieve the sediment quality requirements as outlined herein, a specific borrow area cut geometry for both the offshore and Sebastian Inlet Sand Trap sites was developed based on extensive field evaluations and detailed geotechnical analysis. The results of these analyses are identified in the Contract Documents (Plans and Specifications). The borrow area geometry as identified in the figures shows the limits of the borrow area. Additionally, a magnetometer survey has identified anomalies within the borrow area and a dredge exclusion area is represented in Figures 1 and 3 . The dredge shall not operate within the identified Dredge Exclusion Area. The elevations (depths) of the cuts within the Primary and Secondary Borrow Areasare -31 feet NGVD and -30 feet NGVD, respectively and as identified in Figures 2 and 4; this depth includes a -2 foot overcut allowance. The Sebastian Inlet Sand Trap and its cut geometries are shown in Figures 5 and 6 . The borrow area has multiple cut geometries, which should minimize the potential of encountering rock. The depth of the cuts verify from - 11 feet NGVD to - 16 feet NGVD . The Contractor shall not excavate material from outside the horizontal or vertical dredge delineations. Excavation shall not extend below the allowable depth or within the dredge exclusion area, and shall not occur outside of the spatial limits of the borrow areas as detailed within the Contract Documents (plans and specifications) . There shall be no allowable deviation from these requirements . The designated borrow area volumetric capacities, as approved, far exceed the volumetric requirements of the permitted fill area . 7 DEP Permit No . : 0166929-010-EM The Contractor shall continuously monitor the horizontal and vertical position of the dredge and cutterhead through the use of electronic positioning equipment previously approved by the County. A Differential Global Positioning System (DGPS) or equivalent shall be used to determine the horizontal position of the cutterhead. The horizontal positioning equipment shall maintain an accuracy of ±3 feet. The maximum cutterhead depth shall be measured by an appropriate depth measuring device. The cutterhead depth positioning device shall maintain a vertical accuracy of ±0 . 5 feet and have the ability to perform hourly or real-time tide corrections. The tide shall be measured using a tide staff or electronic gauge in the vicinity of the active borrow site, and the Contractor shall have the ability to retrieve the tide data on a real-time or hourly basis. The Project Engineer shall enforce these requirements during project construction under the terms and provisions of the Technical and Environmental Specifications and through compliance and enforcement provisions as stipulated by the Contract Documents . The Contractor is required to continuously operate the electronic positioning equipment and plot the position of the dredge cutterhead. The positioning equipment shall be installed on the dredge so as to monitor, as accurately as possible, the actual location of the cutterhead. A printout of the horizontal location of the cutterhead in State Plane coordinates and the cutterhead depth (corrected for tide elevation and referenced to NGVD and time) shall be maintained using an interval of 30 seconds for each printed position. Printed and electronic files of the position data (in ASCII format), position plots, the location of the master antenna on the dredge, and the distance and direction from the master antenna to the cutterhead shall be provided to the County as part of the daily report. Monitoring and Reporting The daily review process shall include continuous monitoring of the position of the dredge and cutterhead through the use of global positioning equipment and a tide adjusted depth measuring device. This data shall be reviewed by the on-board Dredge Operator on a continuous basis and reviewed by the Contractor and Site Representative daily. The Contractor shall be available to the Dredge Operator at all times in the event that a problem or difficulty arises with the dredge or dredging operation. The daily report shall include the location of the cutterhead in State Plane coordinates and the cutterhead depth, corrected for tide elevation and referenced to NGVD and time, taken at 30 second intervals. Additionally, the daily report shall include an assessment of the quality and volume of material being dredged. Remediation The Contractor is charged with ensuring the correct volume of material is placed within the beach fill template along the Sectors 1 and 2 shoreline and to guarantee that excavation shall not extend below the allowable depth, within the dredge exclusion area, or outside of the spatial (horizontal) limits of the borrow areas as detailed within the construction documents and the issued Permits . The Contractor shall be responsible for establishing such control as may be necessary to ensure strict adherence 8 DEP Permit No . : 0166929-010-EM to the stipulated horizontal, vertical, and exclusion area limits of the borrow area. If rock or clay is encountered within the borrow area, or if dredging produces excessive turbidity, the Contractor shall immediately raise the cutterhead and adjust the location of the cutterhead to a position where more acceptable material is present. In the event that undesirable material is encountered and the dredge must be relocated, the position of the undesirable material shall be noted, and the County and Site Representative shall be immediately informed. Any rock or clay that is deposited on the beach shall be removed from the Project site and disposed of in areas provided by the County at the expense of the Contractor. The Contractor shall excavate within the borrow areas in a uniform and continuous manner and, if advised by the County or the Engineer that sediment being discharged on the beach is unsuitable, the Contractor shall change the location and/or depth of excavation, within the limits of the borrow areas and outside of the dredge exclusion area, as required to provide the most desirable fill quality in the beach fill (Project) area available. 9 -n v ff I I VESSEL INGRESS/EGRESS B IR-S-3 �'I CORRIDOR @D .� 28.50 777' � I :E R2402� -..- MRS,57 - 24.0 - - _S-5 R-S-1 <. -.. 22.6 25.8 R�5-4 - . . rR3 B / / iT 3 IR-S-28 I 2].8 J E SUB-AREA 1 / -mQ&;ivmk- N 0 (500 Scale in Feet BORROW AREA CORNER COORDINATES POINT FASTING NORTHING VESSEL CORRIDOR COORDINATES i 884475.69 1185497.77 POINT EASTING NORTFIING 2 884248.57 1180426.05 A 884370.42 1183147 .07 3 883253.00 1180547.48 B 884356.99 1182847.08 4 883476.69 1 1185542.50 _ I rGEN11 LILTES: MAGN OMETER ANOMALIES SUB-AREA 1 WITH CO RDINATES WITH 60RROW AREA 1 .
