Dear Mr. Bodnar:

John E. Skvarla, III
Secretary
This letter of refinement is in reference to your 14 November 2014 email on behalf of the
NC Division of Marine Fisheries (NCDMF), requesting a modification of Major CAMA Permit
Number 94-14 issued to NCDMF on 27 October 2014. Permit Number 94-14 was issued for the
expansion of the boundaries of artificial reef AR-298, located 3.5 miles north of Silver Lake in
Ocracoke in Dare County, to encompass ±76.36 acres.
You have requested a change to increase the tonnage of precast concrete units from
550 tons to 900 tons in the approved location shown on Figure 7 dated 14 November 2014
(attached). This area was approved for 100% coverage of the 4.575 acres and this proposal will
not result in an increase of the permitted footprint. In no case will the height exceed the
minimum vertical navigation clearance of 7 feet at normal water level. Your request to increase
the tonnage of precast concrete material from 550 tons to 900 tons is hereby authorized. All
work must be carried out in accordance with your revised plat dated 14 November 2014
(attached).
All permit conditions still apply and remain unchanged. The expiration date of this permit
is 31 December 2017. Thank you for your time and cooperation in this matter. If you have any
questions, please don't hesitate to contact me in the Washington Regional Office at 252-948-
3852.
Sincerely,
David W. Moye
District Manager
Washington Regional Office

Letter of Refinement
AR-298 Ocracoke
NC Division of Marine Fisheries
Artificial Reef Program
The NC Division of Marine Fisheries obtained permit # 94-14 (expiration date December 31,
2017), to expand and enhance AR-298 near Ocracoke, North Carolina. Materials identified in the
CAMA documentation include crushed concrete, Reef Balls^", precast concrete and concrete pipe.
The NC DMF artificial reef program intends to refine the original permit by increasing the
tonnage of precast concrete depicted in Figure 7 of the CAMA permit. Additional material were
obtained which will increase the overall tonnage from approximately 550 tons to approximately 900 tons
and therefore increasing the individual patch reef tonnage from approximately 110 tons to 180 tons.
The original CAMA permit noted that the entire 4.575 acres depicted in Figure 7 will be disturbed
providing 100% coverage. The increase in tonnage will therefore not augment the disturbed footprint,
while staying below the intended minimum vertical clearance of 7 feet at normal water conditions rather
than mean low water. Please refer to the updated Figure 7 for the refinements described here. This
Figure 7 supersedes all past versions.

Concrete precast materials will consist of rectangular units known as waffle boxes, risers, catch basins or solid boxes,
and piling cutoffs. These rectangular units vary In size and shape, with no units greater than 5 feet in height and no
. more than 6,000lbs (3 tons). Approximately 900 tons of the precast units will be deployed in 4.575 acres
� Material will cover the entire acreage of each patch reef totaling 4.575 acres. Legend
