Dear Mr. Trokhin:

You requested reverification of an activity that we previously verified on February 18, 2026, under the 2021 Nationwide Permits. The file number is SAJ-2025-00570. The activity would result in repairs to 15 pilings supporting the existing Bob Sikes Fishing Bridge. The project is located in Santa Rosa Sound immediately north of Santa Rosa Island, and adjacent to Pensacola Beach Boulevard (Hwy 399), at Latitude 30.345732 ° and Longitude -87.151553 °, Pensacola Beach, Florida.

Your activity is authorized by Nationwide Permit (NWP) number 3. This reverification is based on the activity being performed in accordance with the drawings attached to our previous letter; the terms and conditions of the 2026 NWPs found in the January 8, 2026, Federal Register (91 FR 768); the Jacksonville District regional conditions dated February 13, 2026; and the general conditions and special conditions and attachments in our previous letter.

This verification is valid until March 15, 2031. Furthermore, if you commence or are under contract to commence this activity before the date that the relevant NWP expires or is modified or revoked, you will have 12 months from the date of expiration, modification or revocation of the NWP to complete the activity under the present terms and conditions of this NWP.

If during the ground disturbing activities and construction work within the permit area, there are archaeological/cultural materials encountered which were not the subject of a previous cultural resources assessment survey (and which shall include, but not be limited to: pottery, modified shell, flora, fauna, human remains, ceramics, stone tools or metal implements, dugout canoes, evidence of structures or any other physical remains that could be associated with Native American cultures or early colonial or American settlement), the Permittee shall immediately stop all work and

-4-ground-disturbing activities within a 100-meter diameter of the discovery and notify the Corps within the same business day (8 hours). The Corps shall then notify the Florida State Historic Preservation Officer (SHPO) and the appropriate Tribal Historic Preservation Officer(s) (THPO(s)) to assess the significance of the discovery and devise appropriate actions.

c. Additional cultural resources assessments may be required of the permit area in the case of unanticipated discoveries as referenced in accordance with the above Special Condition; and if deemed necessary by the SHPO, THPO(s), or Corps, in accordance with 36 CFR 800 or 33 CFR 325, Appendix C (5). Based, on the circumstances of the discovery, equity to all parties, and considerations of the public interest, the Corps may modify, suspend or revoke the permit in accordance with 33 CFR Part 325.7. Such activity shall not resume on non-federal lands without written authorization from the SHPO for finds under his or her jurisdiction, and from the Corps.

6. Assurance of Navigation and Maintenance: The Permittee understands and agrees that, if future operations by the United States require the removal, relocation, or other alteration, of the structures or work herein authorized, or if in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the Permittee will be required, upon due notice from the Corps of Engineers, to remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United States. No claim shall be made against the United States on account of any such removal or alteration.

7. Turbidity Barriers: Prior to the initiation of any of the work authorized by this permit, the Permittee shall install floating turbidity barriers with weighted skirts that extend within 1 foot of the bottom around all work areas that are in, or adjacent to, surface waters.

8. Manatee Conditions: The Permittee shall comply with the “Standard Manatee Conditions for In-Water Work – 2011” (Attachment 4). The most recent version of the Manatee Conditions must be utilized.

9. Jacksonville District Programmatic Biological Opinion (JAXBO): Structures and activities authorized under this permit will be constructed and operated in accordance with all applicable project design criteria’s (PDCs) contained in the JAXBO, based on the permitted activity. Johnson’s seagrass and its critical habitat were delisted from the Endangered Species Act on May 16, 2022. Therefore, JAXBO PDCs required to minimize adverse effects to Johnson’s seagrass and its critical habitat are no longer applicable to any project. Failure to comply with applicable PDCs will constitute noncompliance with this permit. In addition, failure to comply with the applicable PDCs, where a take of listed species occurs, would constitute an unauthorized take. The NMFS is the appropriate authority to determine compliance with the Endangered Species Act. The most current version of JAXBO can be accessed at the Jacksonville District Regulatory Division web page in the Endangered Species section at:

https://www.sad.usace.army.mil/Missions/Regulatory/Florida/.

JAXBO may be subject to revision at any time. The most recent version of the JAXBO must be utilized during the design and construction of the permitted work.

This letter of authorization does not include conditions that would prevent the ‘take’ of a state-listed fish or wildlife species. These species are protected under sec.

379.411, Florida Statutes, and listed under Rule 68A-27, Florida Administrative Code.

With regard to fish and wildlife species designated as species of special concern or threatened by the State of Florida, you are responsible for coordinating directly with the Florida Fish and Wildlife Conservation Commission (FWC). You can visit the FWC license and permitting webpage (http://www.myfwc.com/license/wildlife/) for more information, including a list of those fish and wildlife species designated as species of special concern or threatened. The Florida Natural Areas Inventory (http://www.fnai.org/) also maintains updated lists, by county, of documented occurrences of those species.

This letter of authorization does not give absolute Federal authority to perform the work as specified on your application. The proposed work may be subject to local building restrictions mandated by the National Flood Insurance Program. You should contact your local office that issues building permits to determine if your site is located in a flood-prone area, and if you must comply with the local building requirements mandated by the National Flood Insurance Program.

http://www.myfwc.com/license/wildlife/ http://www.fnai.org/

This letter of authorization does not preclude the necessity to obtain any other Federal, State, or local permits which may be required.

STANDARD MANATEE CONDITIONS FOR IN-WATER WORK

The permittee shall comply with the following conditions intended to protect manatees from direct project effects:

a. All personnel associated with the project shall be instructed about the presence of manatees and manatee speed zones, and the need to avoid collisions with and injury to manatees. The permittee shall advise all construction personnel that there are civil and criminal penalties for harming, harassing, or killing manatees which are protected under the Marine Mammal Protection Act, the Endangered Species Act, and the Florida Manatee Sanctuary Act.

b. All vessels associated with the construction project shall operate at "Idle Speed/No Wake” at all times while in the immediate area and while in water where the draft of the vessel provides less than a four-foot clearance from the bottom. All vessels will follow routes of deep water whenever possible.

c. Siltation or turbidity barriers shall be made of material in which manatees cannot become entangled, shall be properly secured, and shall be regularly monitored to avoid manatee entanglement or entrapment. Barriers must not impede manatee movement.

d. All on-site project personnel are responsible for observing water-related activities for the presence of manatee(s). All in-water operations, including vessels, must be shutdown if a manatee(s) comes within 50 feet of the operation. Activities will not resume until the manatee(s) has moved beyond the 50-foot radius of the project operation, or until 30 minutes elapses if the manatee(s) has not reappeared within 50 feet of the operation. Animals must not be herded away or harassed into leaving.

e. Any collision with or injury to a manatee shall be reported immediately to the Florida Fish and Wildlife Conservation Commission (FWC) Hotline at 1-888-404-3922. Collision and/or injury should also be reported to the U.S. Fish and Wildlife Service in Jacksonville (1-904-731-3336) for north Florida or Vero Beach (1-772-562-3909) for south Florida, and to FWC at ImperiledSpecies@myFWC.com

f. Temporary signs concerning manatees shall be posted prior to and during all in-water project activities. All signs are to be removed by the permittee upon completion of the project. Temporary signs that have already been approved for this use by the FWC must be used. One sign which reads Caution: Boaters must be posted. A second sign measuring at least 8 ½” by 11" explaining the requirements for “Idle Speed/No Wake” and the shut down of in-water operations must be posted in a location prominently visible to all personnel engaged in water-related activities. These signs can be viewed at MyFWC.com/manatee. Questions concerning these signs can be sent to the email address listed above.

Galvanic Strip Anodes

Notes:

1. Clean pile surface of oil, grease, dirt, marine growth and other foreign materials that could prevent proper bonding between the old concrete and the new cement grout as per FDOT

SPEC. PROVISION 457.

2. Locate center rebar on one face of pile using a pachometer and core-drill a 2 inch diameter access hole through the concrete to expose the steel. Drill and tap the rebar to accept a 5/16 inch stainless steel threaded rod for negative connection. After installation, the rod shall extend a minimum of 1 1/2 inches outside of the existing pile surface. Seal the core hole with sand-cement mortar.

3. Sandblast exposed reinforcing steel to "near white metal"

4. Place reinforcing steel cage along with Galvanic anode strip around pile.

5. Set forms for concrete jacket. (Treat forms with an approved form release agent before placing concrete)

6. Dewater forms and place concrete. Leave forms in place for a minimum of 72 hours.

7. Because the marine biofilms will begin to develop on submerged surfaces immediately after cleaning, which will cause the improper bonding, keep the time interval between surface preparation and concrete placement to an absolute minimum preferably less than 36 hours.

8. Install bulk anode on pile (using clamp brackets) at a maximum elevation of 2 feet below low tide. Secure anode wire to pile using stainless steel clamps and hardware.

9. Route zinc band and bulk anode wire to PVC connection box and connect to reinforcing steel through stainless steel threaded rod to provide a closed circuit system.

Notes:

2. For Beam Crack Repair, follow

Crack Repair Procedure.

EXISTING REINFORCED CONCRETE

Crack Repair Procedure:

A. Remove loose or delaminated concrete.

B. Undercut all exposed reinforcing steel by removing concrete from the full circumference of the steel.

The minimum clearance between the concrete substrate and reinforcing steel shall be specified in the manufacturer's recommendations.

C. Concrete removal shall continue along the reinforcing steel until no further delamination, cracking, or significant rebar corrosion exists and the reinforcing steel is well bonded to the surrounding concrete.

D. Clean exposed reinforcing steel of rust, mortar, etc. to provide sufficient electrical connection and mechanical bond.

E. Galvanic anodes shall be installed along the interface between new and old concrete at a maximum spacing of 24".

F. Place galvanic anodes as close as possible to the patch edge while still providing sufficient clearance between anodes and substrate to allow the repair material to fully encase the anode with a minimum concrete mortar cover over the anode of 1 in. If necessary, increase the size of the repair cavity to accommodate the anodes.

G. The tie wires shall be wrapped around the cleaned reinforcing steel at least one full turn in opposite directions and then twisted tight to create a secure electrical connection and allow no anode movement during concrete placement.

H. If repair materials with resistivity greater than 15,000 ohm-cm are to be used or if the resistivity is unknown, pack Galvashield Embedding Mortar or equivalent between the anode and the substrate concrete to create a conductive grout bridge ensuring no voids exist.

I. Contractor shall seal cracks in accordance with Section 411 of the Standard Specification. Crack to be sealed will be at the direction of the Engineer.

EXISTING STEEL H-PILE WITH JACKET

Crack Repair Procedure:

A. Follow procedure listed above for connection to reinforcing steel.

B. For alkali activated anode connection to steel pile, see manufacturer's procedure.
