This permit was subsequently renewed on January 22, 2020, and modified on December 8, 2022, and has an expiration date of December 31, 2025. This letter serves as written notice of project initiation as required in Condition 7 of the permit. Please find attached to this letter revised permit drawings dated September 13, 2023, which provide the location of the proposed channel for the upcoming event. The project includes maintenance dredging within a portion of the Hatteras Inlet Connector Channel, which runs between the inlet gorge and the southern portion of Sloop Channel, in proximity to Ocracoke Island. This channel is locally referred to as the "Hatteras Connector Channel". The attached plan view drawing shows the locations along the Hatteras Connector Channel in which maintenance dredging is proposed for this event. Two (2) separate channel segments were identified in which maintenance dredging is required, namely Eastern and Western Connector Channels. The attached plans also include the disposal area, avoidance areas identified through cultural resource surveys, submarine cables and a 100-foot buffer around the cables, and previously mapped submerged aquatic vegetation (SAV) resources in the vicinity. Please note the Connector Channel Corridor shown on the drawings incorporates the expanded dredge corridor allowed for by the modification to CAMA Major Permit #129-16, dated December 8, 2022. At present, the proposed maintenance event is anticipated to commence around October 1st and include approximately 14 days of dredging in the Eastern and Western Connector Channel segments shown on the attached drawings. The event is anticipated to be completed prior to October 14th. The event is proposed to utilize the special use Dredge Miss Katie, owned and operated by EJE Dredging Services. Material dredged from the channel by the Miss Katie will be placed in the nearshore disposal location shown on the attached drawings. As you are aware, the Major CAMA Permit (#129-16) allows for maintenance of a 200 ft. wide channel to a depth of-12ft. MLW. Based on the availability of funds, dredge availability, and conditional surveys conducted September 6, 2023, the proposed channel dimensions for this upcoming dredging event are to establish a 200-foot wide channel at elevation -12 ft. MLW. Based on the conditional survey from September 7, 2023, a total of approximately CResre� P RRiECiIGN ENGINEERING COASTAL PROTECTION ENGINEERING OF NORTH CAROLINA, INC. Page 12 88,100 cy of material could be excavated above the -12 ft. MLW permitted dredge depth from within the Eastern Portion and the Western Portion of the channel. Due to budgetary constraints, however, it is expected that Miss Katie will remove approximately 25,000 cy during the upcoming event. The proposed channel is shown in the attached drawings, including both plan view and cross -sectional view. As required by Special Condition #23 in Dept. of Army Permit #SAW-206-02140, USACE Regulatory must be notified of the location of any known SAV beds at least two (2) weeks in advance of dredging. High resolution aerial imagery by an unmanned aircraft system (UAS), or drone, was obtained on June 8, 2023. The closest SAV resources in proximity to the project area, as delineated from this imagery, are found no closer than within 630 ft from the proposed dredging footprint. Regarding contact information during dredge activities, Jordan Hennessy will be the EJE Dredging point of contact for the Miss Katie dredging operations. Jordan's phone number is (252) 619-3606 and his email is jhennessy@ejedredging.com. I will be the County's agent and can be contacted via cell phone at (910) 443-4471 or via email at kwillson@coastalprotectioneng.com.
