Collier County Government c/o Jay Ahmad 2885 Horseshoe Drive S Naples, Florida 34104

Dear Mr. Ahmad:

Your application for a Department of the Army permit, received on May 28, 2022, has been assigned number SAJ-2009-01021 (NWP-MLT). A review of the information and drawings provided shows the proposed work includes the repair of the existing scour holes and failed scour protection in the vicinity of piers 12 through 16 where significant scour has occurred. No repairs or improvements are required at the remaining piers or the bridge abutments. The project proposes to place clean rubble riprap and bedding stone around the five (5) existing piers. The bedding stone will fill the existing scour hole and the riprap will provide a protective layer to avoid bedding stone and native substrate scouring. The total proposed impact area for the five (5) piers is 0.52 acre (0.104 acre each) based on approximately 84-foot by 60-foot fill dimensions at each pier. The proposed work will occur within the tidal waters of Goodland Bay within the Rookery Bay National Estuarine Research Reserve which is an outstanding Florida water (OFW) and the applicant is requesting a 100-foot mixing zone surrounding the proposed scour protection work and has submitted detailed plans to avoid discharges greater than zero

(0) nephelometric turbidity unit (NTUs) above the background conditions. The applicant will utilize floating turbidity curtains to control erosion and sedimentation within the vicinity and a detailed Turbidity Monitoring Plan is included in the project plans attached to this permit. A submerged aquatic vegetation (SAV) and hardbottom benthic survey was conducted by ESA on September 8, 2021, to document the existing conditions and the presence of SAV and hardbottom habitats. Neither of these resources were documented within the survey area that encompassed piers 12 through 16 and the vicinity of the proposed activities. No impacts to the adjacent mangrove wetlands are proposed or authorized. The applicant will utilize floating turbidity curtains to control erosion and sedimentation within the bay. The activities subject to this permit are authorized pursuant to authorities under Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. § 403) and Section 404 of the Clean Water Act (33 U.S.C. § 1344).

The project would affect waters of the United States, associated with the Marco Channel (a navigable vessel channel but is not a federal channel) of Goodland Bay, in

1) (AP.7.) Education and Observation: The permittee must ensure that all personnel associated with the project are instructed about the potential presence of species protected under the ESA and the Marine Mammal Protection Act (MMPA). All on-site project personnel are responsible for observing water-related activities for the presence of protected species. All personnel shall be advised that there are civil and criminal penalties for harming, harassing, or killing ESA-listed species or marine mammals. To determine which species may be found in the project area, please review the relevant Protected Species List at:

http://sero.nmfs.noaa.gov/protected_resources/section_7/threatened_endangered/in dex.html

2) (AP.8.) Reporting of interactions with protected species:

a) Any collision(s) with and/or injury to any sea turtle, sawfish, whale, or sturgeon occurring during the construction of a project, shall be reported immediately to NMFS’s Protected Resources Division (PRD) at (1-727-824-5312) or by email to takereport.nmfsser@noaa.gov and SAJ-RD-Enforcement@usace.army.mil.

b) Smalltooth sawfish: Report sightings to 1-844-SAWFISH or email Sawfish@MyFWC.com

c) Sturgeon: Report dead sturgeon to 1-844-STURG 911 (1-844-788-7491) or email nmfs.ser.sturgeonnetwork@noaa.gov

d) Sea turtles and marine mammals: Report stranded, injured, or dead animals to 1-

877-WHALE HELP (1-877-942-5343).

e) North Atlantic right whale: Report injured, dead, or entangled right whales to the USCG via VHF Channel 16.

3) (AP.9.) Vessel Traffic and Construction Equipment: All vessel operators must watch for and avoid collision with species protected under the ESA and MMPA.

Vessel operators must avoid potential interactions with protected species and operate in accordance with the following protective measures:

a) Construction Equipment:

i) All vessels associated with the construction project shall operate at “Idle Speed/No Wake” at all times while operating in water depths where the draft of the vessel provides less than a 4-foot (ft) clearance from the bottom, and in all depths after a protected species has been observed in and has departed the area.

ii) All vessels will follow marked channels and/or routes using the maximum water depth whenever possible.

iii) Operation of any mechanical construction equipment, including vessels, shall cease immediately if a listed species is observed within a 50-ft radius of http://sero.nmfs.noaa.gov/protected_resources/section_7/threatened_endangered/index.html http://sero.nmfs.noaa.gov/protected_resources/section_7/threatened_endangered/index.html construction equipment and shall not resume until the species has departed the area of its own volition.

iv) If the detection of species is not possible during certain weather conditions (e.g., fog, rain, wind), then in-water operations will cease until weather conditions improve and detection is again feasible.

b) All Vessels:

i) Sea turtles: Maintain a minimum distance of 150 ft.

ii) North Atlantic right whale: Maintain a minimum 1,500-ft distance (500 yards).

iii) Vessels 65 ft in length or longer must comply with the Right Whale Ship Strike

Reduction Rule (50 CFR 224.105) which includes reducing speeds to 10 knots or less in Seasonal Management Areas (http://www.fisheries.noaa.gov/pr/shipstrike/).

iv) Mariners shall check various communication media for general information regarding avoiding ship strikes and specific information regarding right whale sightings in the area. These include NOAA weather radio, USCG NAVTEX broadcasts, and Notices to Mariners.

v) Marine mammals (i.e., dolphins, whales [other than North Atlantic right whales], and porpoises): Maintain a minimum distance of 300 ft.

vi) When these animals are sighted while the vessel is underway (e.g., bow-riding), attempt to remain parallel to the animal’s course. Avoid excessive speed or abrupt changes in direction until they have left the area.

vii) Reduce speed to 10 knots or less when mother/calf pairs or groups of marine mammals are observed, when safety permits.

4) (AP.10.) Turbidity Control Measures during Construction: Turbidity must be monitored and controlled. Prior to initiating any of the work covered under this Opinion, the Permittee shall install turbidity curtains as described below. In some instances, the use of turbidity curtains may be waived by the USACE project manager if the project is deemed too minimal to generate turbidity (e.g., certain ATON installation, scientific survey device placement, marine debris removal) or if the current is too strong for the curtains to stay in place. Turbidity curtains specifications:

a) Install floating turbidity barriers with weighted skirts that extend to within 1 ft of the bottom around all work areas that are in, or adjacent to, surface waters.

b) Use these turbidity barriers throughout construction to control erosion and siltation and ensure that turbidity levels within the project area do not exceed background conditions.

c) Position turbidity barriers in a way that does not block species’ entry to or exit from designated critical habitat.

d) Monitor and maintain turbidity barriers in place until the authorized work has been completed and the water quality in the project area has returned to background conditions.

e) In the range of ESA-listed corals (St. Lucie Inlet, Martin County south to the Dry Tortugas and the U.S. Caribbean) and Johnson’s seagrass (Turkey Creek/Palm http://www.fisheries.noaa.gov/pr/shipstrike/

Bay south to central Biscayne Bay in the lagoon systems on the east coast of Florida):

i) Projects that include upland earth moving (e.g., grading to install a building or parking lot associated with a dock and seawall project), must install sediment control barriers to prevent any upland sediments from reaching estuarine or marine waters.

ii) The turbidity curtain requirement cannot be waived for any project that moves or removes sediment (e.g., dredging, auger to create a pile, trenching to install a cableline). If turbidity curtains are not feasible in an area based on site conditions such as water current, high wave action, or stormy conditions, the project must undergo individual Section 7 consultation and is not covered under this Programmatic Opinion.

5) (AP.11.) Entanglement: All turbidity curtains and other in-water equipment must be properly secured with materials that reduce the risk of entanglement of marine species (described below). Turbidity curtains likewise must be made of materials that reduce the risk of entanglement of marine species.

a) In-water lines (rope, chain, and cable, including the lines to secure turbidity curtains) must be stiff, taut, and non-looping. Examples of such lines are heavy metal chains or heavy cables that do not readily loop and tangle. Flexible in-water lines, such as nylon rope or any lines that could loop or tangle, must be enclosed in a plastic or rubber sleeve/tube to add rigidity and prevent the line from looping and tangling. In all instances, no excess line is allowed in the water.

b) Turbidity curtains and other in-water equipment must be placed in a manner that does not entrap species within the construction area or block access for them to navigate around the construction area.
