St. Lucie discharge headwall project questions
- Jodie, As I have been putting together the biological assessment for FWS, I have come up with some questions. If you would be able to answer these, that would be really helpful to me. Thanks!
- 1. The December 6, 2011 FDEP construction permit letter that you attached to your March 6 email seems to be missing a couple of pages. The second page of the letter cuts off, and then the attachment starts with page 2 on the following page. Can you provide the missing pages? We received a modified permit from the FDEP last week. Please see attached.
- 2. Can you send me a copy of the sea turtle protection plan that was submitted to the St. Lucie County Development Review Board and that is mentioned in FPLs proposed conditions for work? I have attached the sea turtle protection plan; however, there are additional conditions for sea turtle protection included in the FDEP modified permit.
- 3. What other permits or approvals are needed that relate to sea turtles? The ones I know of are an incidental take permit under the Endangered Species Act, St. Lucie County Development Review Board approval of a sea turtle protection plan, and a construction permit through FDEP. Are there any others 1
in addition to these? No. We have the approval of St. Lucie County and FDEP to move forward with the project. Once we receive the ITP, we will have to go back to consult with FDEP and FWC for relocation of nests due to construction.
- 4. When does FPL anticipate that the discharge headwall project will be completed? The work seaward of the sheet pile will be completed by May 30/June 1. Only dune planting will occur after May 30. The work landward of the wall will continue and is currently estimated to be complete by mid June.
- 5. What will working hours be during the project? Will there be any work after dark, and if so, any associated lighting? Work will only be completed during daylight hours.

FPL ST. LUCIE NUCLEAR PLANT HEADWALL STABILIZATION SPMn112010 4172 Sea Turtle Protection Plan (STPP)
Plant Discharge Canal Headwall Stabilization Project
Introduction St. Lucie County requires a sea turtle protection plan for compliance with LDC 6.04.02. FPL has provided specific management provisions to support protection of sea turtles and their habitat consistent with LDC 6.04.02 and with Florida Fish and Wildlife Conservation Commission (FFWCC) requirements for construction and turtle monitoring when construction activities occur seaward of the dune crest during the nesting season. This document provides the necessary guidance to protect sea turtle habitat, sea turtles, and sea turtle nesting during construction of the FPL seawall and dune.
The main text provides the following:
x Introduction and document organization x Construction Overview x Sea Turtle Protection Plan including o Sea Turtle Nest Monitoring During Construction o Sea Turtle Nesting Seasons and Related Monitoring Activities Three Appendices attached to the main text provide the following:
x Appendix A addresses specific STTP content requirements described in LDC 6.04.02. A, B, C, D, E, F. G, H, I J, K, L, M, and N.
x Appendix B provides a QA/QC plan for the sand used to create the dune. The sand data providing existing sand quality information are included at the end of Appendix B.
x Appendix C comprises a written legal description of the FPL property, as required in LDC 6.04.02(F)(1)(a)(2)
FPL currently supports an ongoing sea turtle nesting survey that includes daily early morning turtle nesting surveys between April and September of each year. Surveys once to twice weekly in March and October complete the effort. The permitted monitoring agent reports the data to FFWCC for inclusion in their turtle monitoring program database. Sea turtle surveys during the construction period (as described below) will provide the information required by St. Lucie County and FFWCC to maintain protective conditions for sea turtle nesting.
Construction Overview The construction project locates on FPL Hutchinson Island Power Plant property in St. Lucie County, FL, landward of and on the dune of the Atlantic Ocean beach (Figure 1). The construction entails placement of a seawall and beach dune to protect the seaward end of the power plant cooling water discharge channel currently threatened by long-term beach erosion. A new Dune Preservation Area (DPZ)
(Figure 2) includes the dune feature in front of and behind the seawall, and extending 280 ft north and south of the seawall including the entire primary dune.

The proposed seawall and dune construction for the FPL Headwall Stabilization project will avoid impacts to marine turtles. The contractor will use the canal maintenance access road (Figure 3) to construct the seawall and place beach quality sand on the beach against the current scarp. That sand will provide a pad for the equipment necessary on the beach side of the construction area. Construction equipment on the sand pad will likely include a small bulldozer or Bobcat to work the sand into the pad, a small drill rig to drill in the tieback rods, and possibly other tracked or wheeled vehicles to deliver materials and equipment during construction. Other heavy equipment will remain on the upland side of the seawall. Because the site is only 400 feet in length and immediately adjacent to the canal maintenance road, the contractor may apply the primary contractor staging area (Figure 3) and pass materials and equipment directly across the proposed seawall location, in many cases without accessing the beach.
If required, the contractor may stage sand and equipment and access the construction site along the beach from the additional staging area (Figure 4). FPL currently maintains this beach access point, which allows FPL biologist and personnel access to the beach for ongoing monitoring activities. If the project requires use of this access, FPL will first survey the existing access to identify existing dune conditions and location of vegetation lines. If the contractor modifies the access area or damages vegetation in the access area along the route between the access and the project site, FPL will require the contractor to restore the impacted areas to preconstruction conditions. As necessary, repairs may include replacement of dune sand and revegetation in compliance with all requirements of the recorded Preserve Area Management Plan (PAMP). All staging of construction equipment and materials will occur off the beach within the primary contractor staging area (Figure 3) or at the additional contractor staging area within the work area at the intake canal (Figure 4). Beachside construction will include only those activities that cannot occur from the upland side of the seawall. No sand placement or other construction activities except foot traffic will occur between May 1 and October 31.
Sand for the dune will comprise material compatible with the native beach sand. Appendix B describes sand quality assurance and control procedures for this project. The contractor will truck in sand from sand mines pre-tested and used by the county, place it at the foot of the scarp and after using the sand as a platform to help construct the seawall will shape it to the permitted dune template. Plantings of sea grape at the top of the dune and sea oats and other species on the dune slope will complete the construction. The Preservation Area Management Plan (PAMP) developed for the project provides additional details of the construction process and planting information. The engineering drawings provide other information and specifications. FPL will stay in contact with the county to maintain currency with county recommendations concerning the sand mines suited to provide sand for St. Lucie County beaches.
To avoid death or injury to marine turtles and impacts to marine turtle nesting habitat and nests, the beachside construction activity will avoid peak turtle nesting season (1 May through 31 October).
Only foot traffic (no vehicles equipment or materials) will enter or operate on the beach side of the seawall during that period. FPL intends full completion of the project by 1 May.
Sea Turtle Protection Plan The sea turtle protection plan first provides a general description of necessary activities of the permitted sea turtle monitor and the construction contractor. The second part of the plan describes the period-specific monitoring activities that must occur before each days construction may begin and before, during, and after the construction period.

STPP FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Nest Monitoring During Construction To verify and ensure impact avoidance during construction, the permitted monitoring agent will monitor the site as required by FFWCC. The agent will monitor the beach in front of the construction site prior to the start of construction each morning and follow all FFWCC turtle nest and nesting activity recording requirements (identified below). Table 1 provides the information that the agent will collect and report. The monitor will also review LDC Section 6.04.02.g.6.i and collect any additional information required by that section. FPL will provide the daily monitoring records and a report summarizing monitoring results within 60 days of all construction completion (including planting). Monitoring will occur from the mean high water line landward to the toe of dune (where present), or as far landward as appropriate (e.g. until the presence of the dune scarp, or a roadway, etc.). In accordance with LDC Section 6.04.02.G.h, monitoring will occur for all areas where construction occurs within turtle nesting habitat, including areas upon which equipment and materials move to and from the construction site.
If a nest appears to require relocation (due to location on the beach with respect to the water level, construction activity, or other reason) the biologist will, as required by FFWCC regulations, contact the appropriate FFWCC representative and alert them to the issue. All nest relocations will occur with the direction of FFWCC staff.
Prior to the start of construction, FPL biologists will also educate the contractor on possible environmental impacts from project construction and on means to avoid and minimize impacts to turtle nesting habitat, nesting turtles, and turtle nests. FPL will provide and require the contractor to post a list describing the required turtle monitoring program and actions required when construction disturbs a nest.
Nest relocations in association with construction activities must cease when construction activities no longer threaten nests.

Nest relocation will occur only for those nests that construction activities may affect. If a turtle constructs a nest where construction may impact the nest, a permitted agent or trained FFWCC staff member must relocate the eggs. Only personnel with prior experience and training in nesting survey and egg relocation procedures may relocate a nest. Personnel performing nest searches must perform their work under the direct supervision of a valid FFWCC permit holder and personnel performing relocations must hold a valid FFWCC Permit, issued pursuant to Florida Administrative Code Rule 68E-1. The authorized personnel performing the relocation will select the relocation site in consultation with FFWCC or FFWCC will perform the relocation. The contractor must not initiate daily work until the sea turtle permit holder performing the surveys has notified the contractor that the morning survey is complete.
Construction activities may not occur in any location prior to completion of the necessary sea turtle protection measures.
Nests deposited within areas where construction activities have ceased or will not occur for 65 days must be marked and left in situ unless other factors threaten the success of the nest. The sea turtle permit holder must install an on-beach marker at the nest site and a secondary marker at a point landward as possible to assure the future location of the nest will be possible should the on-beach marker be lost.
The permit holder must also install a series of stakes and highly visible survey ribbon or string to establish a 10-foot radius around the nest. No activity of any kind will occur within this radius. Any activity will occur outside and adjacent to that radius that could result in impacts to the nest. Nest site inspections must occur daily to assure nest markers remain in place and that construction has not disturbed the nest.
Post-construction nesting surveys shall occur daily and continue through October 31 of the construction year, as outlined above and in Table 2 below.
If at any time construction disturbs a nest, the contractor will immediately and in the following order contact
- 1. FFWCC hotline at 1-888-404-FWCC (3922) Cellular phone *FWC or #FW
- 2. Megan Koperski, the local FFWCC representative responsible for sea turtle compliance enforcement.
- 3. The sea turtle monitoring and nest relocation permit holder, InWater Research, for nest relocation or other appropriate action as determined by Meghan Koperski or other authorized FFWCC representative.
The contractor will receive emergency phone number, names, and procedures prior to receiving a notice to proceed with construction.

STPP FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Nesting Seasons and Related Monitoring Activities St. Lucie County recognizes turtle nesting season from 1 March through 15 November. Outside that period, the county requires additional activities to ensure protection of turtle nesting activities and habitats. The Florida Fish and Wildlife Commission (FFWCC) and the US Fish and Wildlife Service (FWS) recognize slightly different sea turtle nesting season periods (Table 2)
Table 2. State/Federal Regulatory Nesting Periods, St. Lucie County, FL Nesting Period Period Name 1 March - 30 April Early Nesting Season 1 May - 31 October Peak Nesting Season 1 November - 30 November Late Nesting Season The FFWCC associates specific nesting season restrictions for St. Lucie County beaches at least as stringent as those the county includes in their codes. Combining St. Lucie County, FFWCC, and USFWS management requirements and recommendations resulted in the following rules for sea turtle protection on the headwall stabilization project. The protection specifications below are modeled on those submitted by St. Lucie County to the FDEP and USACE for the South Beach and Dune Restoration Project (FDEP Permit No. 0154626-001-JC, St. Lucie County; USACE Permit No: SAJ-2009-03448(IP-GGL)). Minor differences between the conditions below and the permit application conditions result primarily from the different construction activities proposed.
x All construction will occur during daylight hours (sunup to sundown).
x Nesting surveys must occur daily between sunrise and 9 a.m.
x If nests are found during a preliminary (prior to construction notice to proceed) site survey and cannot be relocated to a nearby self-release beach site in a secure setting where artificial lighting will not interfere with hatchling orientation, construction will wait for 65 days or until all potentially affected nests have hatched.
x A state-permitted agent will perform all nesting survey activities.
The paragraphs below note specific construction and survey activities associate with each of the sea turtle nesting seasons shown in Table 1.
Early Nesting Season (1 March - April 30): Beachside construction activities may begin only after the daily notice from the sea turtle permit holder that they have completed the required survey activities:
x Daily preconstruction search for turtle nests between 6 am and 9 am.
x When search activities locate a nest the following data are recorded o Record the GPS location of nest o Mark a 10 ft perimeter around nest with wooden stakes and plastic construction flagging x If construction cannot avoid nest disturbance, nest relocation must occur before construction may begin. Nests relocation may only occur during the construction period. Nest relocation must occur no later than 9 a.m. the morning following deposition to a nearby self-release beach site in a secure setting where artificial lighting will not interfere with hatchling orientation. FFWCC staff will direct relocation efforts (including selecting or approving a proposed relocation site) or will perform the task.
9
STPP FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 x Nesting surveys must be initiated 65 days prior to construction activities, or by March 1, whichever is later.
Peak nesting season (1 May - 31 October): No construction activity or materials other than foot traffic on the beach.
x Daily preconstruction search for turtle nests between 6 am and 9 am.
Late Nesting Season (1 November - 30 November): Construction work may occur with the following stipulations:
x Daily preconstruction search for turtle nests between 6 am and 9 am x GPS location of nests x 10 ft perimeter around nests x If construction activities cannot avoid disturbing a nest, nest relocation must occur before 9 am and before construction may begin. Nests relocation may only during the construction period. Nest relocation must occur no later than 9 a.m. the morning following deposition to a nearby self-release beach site in a secure setting where artificial lighting will not interfere with hatchling orientation. FFWCC will direct relocation efforts (including selecting or approving a proposed relocation site) or will perform the task.
x Nesting surveys must begin 65 days prior to the start of the construction period or by 1 November, whichever is earlier.

- 2. The construction will occur to the maximum extent possible between November 16 and February
- 29. See the STPP for details of protection activities for work conducted outside those periods.
- 3. The work will not extend beyond the primary dune. However, the daily turtle nesting surveys will include the area between the primary dune and water line to ensure turtle nest identification and protection.
- 4. No nighttime work will occur; no lighting will occur as part of the construction project.
- 5. No nighttime work will occur. Therefore the project will comply with conditions in 6.04.02(L)
- 6. The STPP includes those protective/mitigation measures described in this section. The STTP also includes other protective/mitigation measures.
Concerning Section (G)6e:The project includes no exclusion fences in sea turtle nesting habitat.
(H) Standards for Site Development
- 1. The project includes no construction of buildings, recreational facilities, walkways, beach access points, parking lots or other similar features that would occur or border on sea turtle habitat.
- 2. The proposed seawall portion running parallel to the shoreline comprises a structure flush with the top of the dune; it does not rise above the ground. The end portions of the north and south return walls, which run perpendicular to the shoreline to the west (away from the beach) may be partially (one to several feet) exposed. However, aboveground exposure of the seawall return walls occurs west of the dune and not within turtle nesting habitat.
(I) Standards for New Beachfront Lighting (I)1-6 This project includes no new beachfront lighting.
(I)7. FPL vehicles now use and will in the future use the discharge canal maintenance road at night. This use may result in temporary visibility from the beach of those vehicle lights. FPL proposes the placement of sea grapes in the portion of the area where the maintenance road runs parallel to the shoreline (top of dune). The construction contractor will remove and stockpile sea grapes existing within the project work area and replace them on the site at the end of A-2
FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Protection Plan Appendix A construction. New sea grape plants will supplement the existing sea grapes as necessary to provide a screen of sea grapes for the top edge of the dune in the project area.
(J) Standards for Existing Beachfront Lighting The site currently includes no beachfront lighting.
(K) Special Lighting Restrictions during the Nesting Season Work will occur only between sunup and sundown.
(L) Standards for New Beach Access Points The project includes no permanent new beach access point. All beach access will occur within the construction work area through a temporary access point. The contractor will clear vegetation, remove, and reserve sea grapes growing within the work area. Sand for the dune, brought in along and placed on the beach from the existing maintenance road will provide a platform for vehicles to access the beach side of the project area. Equipment will drive from maintenance road to the sand platform. With seawall construction completed, construction will turn to completing the dune by adding any additional sand to allow construction of the dune to the design template.
Equipment on the dune will serve primarily to drill seawall tieback rods into soil and to the shape the dune to the desired template. Equipment will exit onto the maintenance road from the dune, which will match the elevation of the maintenance road. After completion of the dune, plantings of seagrapes will close the temporary access point, and plantings of appropriate herbaceous vegetation on the dune will complete the closure of the temporary access point.
(M) Standards for Existing Beach Access Points The project work area includes no existing beach access points.
(N) Standards for Mechanical Beach Cleaning The project includes no required beach cleaning activity. However, construction includes placement of sand on the beach above the mean high tide elevation and the shaping of that sand into a dune.
- 1. Compliance with County and State Beach-Dune Preservation Policies. Equipment, methodologies, and points of access for the construction will remain consistent with long-term beach-dune preservation policies established by the county and the state.
- 2. Timing All construction, including beachside activity will occur between sunup and sundown.
- 3. Mode of Operations x For the period 1 March through 30 April and 1 November through 30 November, motorized construction equipment operating on the beach side of the project area will remain above the mean high tide line.
x Equipment necessary for construction of the seawall and dune will remain on the sand placed by the contractor; construction equipment will avoid the existing beach.
x The construction method does not produce small debris that might remain on site.
The construction plan includes no debris removal activity (e.g. raking). Final site cleaning will remove any debris left by workers (e.g. paper coffee cups, sandwich wrappers etc.).

FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Protection Plan Appendix B APPENDIX B Dune Fill QA/QC Plan Discharge Canal Headwall Stabilization Project St. Lucie County, Florida In conjunction with construction of a protective seawall, the project proposes to reconstruct the dune that fronts Florida Power and Lights (FPL) discharge canal headwall structure in the vicinity of FDEP reference monuments R-81. Dune construction will include the placement of approximately 2,350 cubic yards of fill along with planting native beach vegetation immediately following dune construction.
Appendix A to this document provides laboratory testing results for sand samples from the site as collected and analyzed by Dunkelberger Engineering and Testing (reported January 27, 2010). The laboratory analysis and accompanying characterization by Taylor Engineering provides baseline documentation for the sand on the existing beach.
The contractor will construct the dune using sand material from an upland sand mine pre-tested by St. Lucie County as a source for beach quality sand. Currently, the pre-tested sand mines include:
x Oslo Pit 86th x Ranch Road x Stuart Mining Pit At the time of construction, the contractor will verify that at least one of the listed mines has sufficient beach quality material for the project. If these mines are not available, the contractor may apply a similar pre-tested beach material sand source that meets the requirements of St. Lucie County, FPL, and the Dune Fill QA/QC plan herein.
The purpose of the Dune Fill Quality Assurance (QA) and Quality Control (QC) Plan is to make certain that the sand from the upland source will meet the standards required by the State of Florida, St.
Lucie County, and the projects Coastal Construction Control Line permit. The QC Plan for the subject project will outline requirements placed on the Contractor to verify that source sand meets quality standards and that the Contractor takes appropriate remedial actions for unsuitable material, if necessary.
The QA Plan outlines the steps taken by the permittee (FPL) to observe, sample, and test the placed sand to assure compliance with the permit.
Quality Control Plan The following technical requirements address the source of the sand, sand quality monitoring on the dune, and remedial actions if necessary. FPL will enforce the following quality control requirements during bidding and the execution of work.

FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Protection Plan Appendix B
- 5. Carbonate content of the fill material must be between 30% and 70%.
- 6. Any fill material determined by FPL to be in non-compliance with these specifications, or otherwise non-beach-compatible, must be promptly removed by the Contractor at no expense to FPL. Burial of such material within the berm or dune is specifically and strictly prohibited.
- 7. Sand Color: At minimum, using the Munsell Color Scale, all sand placed must have a value of 5 or higher and a chroma of 1 or 2 when graded on the 2.5YR, 7.5YR or 10YR hues under air dry sample conditions. Material with higher value grades is acceptable.
- 8. The grain size distribution, color, and texture of the typical fill material provided by the Contractor must be equivalent to the data and sand samples provided by the Contractor as part of the Bid submittal.
Placement
- 1. General: Dunes will be constructed using approximately 5.3 cubic yards of sand per linear foot of shoreline on average. The slope of the seaward edge of the dune will be no steeper than 2.5 horizontal to 1 vertical. The Contractor must construct the actual dune volume and shape per the requirements illustrated in the construction plans. Field adjustment of the design may be necessary; all field adjustments must be approved by FPL.
- 2. Misplaced Material: Fill sand lost in transit or deposited onto the upland beyond the specified limits of fill must be removed at the Contractor's expense if so directed by FPL. Placement or spreading of the fill material landward of the landward limit of fill (i.e., into existing vegetated dune) is specifically prohibited.
- 3. Tolerances- Elevation: The dune fill must be graded to remove depressions in the dune's surface, and the seaward face (and landward face where applicable) of the dune fill must be graded to a slope no steeper than 2.5 horizontal to 1 vertical with FPL to approve final grading based on submittal of a signed and sealed as-built survey. Final grades must meet elevations as specified on the drawings to within six inches
- 4. Placement at Existing Structures: Fill must be placed around all structures in a manner that avoids damage to those structures. Nonetheless, depressions, gullies, or other pockets in the dune elevation in the vicinity of these structures must not occur. Manual labor (shovels, etc.)
will be required to distribute fill sand around structures, and pilings, etc.
Quality Assurance Plan FPL will seek to enforce the construction contract and FDEP permits related to sand quality and quantity. In order to do so, FPL will follow the following steps:
- 1. FPL will perform construction observation to reasonably assure that the Contractor works in conformance with the required contract and permit conditions. FPL will provide daily observation and contract administration. The Contractor will submit daily reports describing the ongoing sand placement operations.
B-3
FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Protection Plan Appendix B
- 2. FPL must provide onsite observation by an individual with training or experience in construction observations, the permit conditions, and the sand requirements.
- 3. FPL will discuss the project Quality Control Plan that the Contractor will implement as a matter of importance at the pre-construction meeting. FPL will require the Contractor to acknowledge the goals and intent of the above-described QC Plan in writing prior to the issuance of a Notice to Proceed.
- 4. FPL will review the Contractors daily reports which characterize the nature of the sands excavated from the upland mine and placed along the project area.
- 5. Any addendum or change order to the Contract between FPL and the Contractor must determine whether the change in scope will potentially affect the above-described QC Plan.
- 6. To assure that the fill material placed on the beach complies with the permit, FPL must conduct assessments of the sand as follows:
- a. FPL will collect twice-weekly grab sand samples from the placement site and visually assess grain size, Munsell color, shell content, and silt content. The grab sample will be representative of the sand placed over the sample period (2-3 days).
Considering the total volume of sand and proposed construction schedule, each sample will represent approximately 500 to 600 CY of placed sand material. FPL will archive the sample with the date, time, and location of the sample and will visually compared to the acceptable sand criteria required in the project specifications and repeated in this Quality Control plan. If determined necessary by FPL, it will conduct quantitative assessments for grain size, shell content, and Munsell color. FPL will keep a record of each sand evaluation available to FDEP upon request and will store all samples until project completion.
- b. If FPL determines that the grain size, Munsell color, shell content, and silt content do not comply with the quality requirements outlined in the Quality Control Plan, FPL will immediately instruct the Contractor to cease material placement operations and take whatever actions necessary to avoid further placement of unsuitable material. FPL will then determine if the dune placement requires remediation.
Remediation efforts may include dune tilling or blending of unacceptable fill material with adjacent material or excavation and returning of material to the source mine. Additional sand testing must be conducted following any remediation effort.
FPL will immediately notify FDEP of any remediation efforts and report the sand inspection results. FPL may consult FDEP when necessary.
- c. Upon completion of an acceptance section of constructed dune, FPL will collect a representative sand sample and replicate sample at three locations (Station 12+60, Station 11+20, and Station 9+60, as noted on the project grading plan) to quantitatively assess the grain size distribution, Munsell color, shell content, and silt content for compliance. Sample collection will occur approximately 12 inches below the surface within the limits of the constructed dune. FPL will note the existence of any layering while collecting the sample. Mixing will occur for each sand sample to develop a homogeneous consistency. FPL will collect one replicate sample (a B-4
FPL/St. Lucie Nuclear Plant Headwall Stabilization SPMn112010 4172 Sea Turtle Protection Plan Appendix B minimum of one half pound sample) at each sampling location. FPL will send one of the sand samples collected for laboratory analysis and will archive the replicate sample. Labels for all samples and laboratory test results will include the Project name, nearest, FDEP Monument designation, State Plane (X,Y) coordinate location, date of obtaining the sample, and "Construction Dune Sample. A Certified Testing Laboratory will perform all laboratory testing. The laboratory will perform all sieve tests in accordance with the applicable sections of ASTM D422-63 (Standard Test Method for Particle-Size Analysis of Soils), ASTM D1140 (Standard Test Method for Amount of Material in Soils Finer than No. 200 Sieve), and ASTM D2487 (Classification of Soils for Engineering Purposes) as well as FDEP Form 62B-56.900(3) F.A.C. Sieve tests will include the following U.S. Standard Sieve Numbers: 3/4, 5/8, 3.5, 4, 5, 7, 10, 14, 18, 25, 35, 45, 60, 80, 120, 170, and 230.
The laboratory will keep a running total of the tabulated results for each parameter to obtain an overall average for the project. Each sample results will state whether the sample MEETS or FAILS the FDEP Sand Rule requirement. FPL will submit sand testing results to the FDEP following dune construction. In the unlikely event that a section of beach contains sand that does not comply with the permit standards, then FPL will notify the FDEP. Notification will indicate the volume, plan extent, and location of any unacceptable dune areas and remediation planned. Delineating the area of unacceptable material may require additional testing. FPL will report the results of any additional testing to the FDEP. Remediation efforts, subject to approval by the FDEP, may include dune tilling or blending of unacceptable dune fill material with adjacent material or returning the material to the source mine. FPL will conduct additional sand testing following any remediation effort.
In addition to reviewing the required as-built survey submitted by the Contractor, FPL will visually review the project site to verify that the elevations of the constructed dune adhere to the requirements of the plans and specifications. In the event that a deficiency is identified, FPL will require the Contractor to correct placement.
