thorough understanding of the information,conditions,and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
I • Section A. (3.) has been updated to require electronic submission of
effluent data reports (DMRs). Federal regulations require electronic
submittal of all discharge monitoring.
• An updated outfall map has been included.
• Monitoring for turbidity has been added to determine compliance with 15A
NCAC 02B.0211 (21).
The NPDES standard conditions(Parts II, III,and IV)that are a part of the permit are not included in this draft
document(cover,map,and Part I).The conditions are the same as in your current permit except that agency and

the Winston Salem Regional Office of this development and discuss temporary,alternate means for
disinfection of the effluent.
b. If chlorine compounds are used as temporary means of disinfection,the total residual chlorine(TRC)
concentration of the effluent shall be monitored daily while this method of disinfection is in use and
values shall be reported on the discharge monitoring report. TRC in the effluent shall not exceed

the receiving stream.
c. In the event that TRC monitoring should occur,the Division shall c.•sider all effluent TRC values
reported below 50 µg/L to be in compliance with the permit. Ho 'er,the Permittee shall continue to

8. PROJECT SUMMARY:
The proposed project is for a living shoreline that would be constructed in four sections
totaling 3,520 ft. It would be placed along the mainland of the Hammocks Beach State Park
shoreline.
9. NARRATIVE DESCRIPTION:
The Hammocks Beach State Park project is located at 1572 State Road 1511, Swansboro,
Onslow County.
The mainland property is 290 acres in its entirety. Queen Creek runs along the west side of the
property. The property is cleared at some locations with a visitor center, campsites,trails,
maintained lawn grass,parking lots, roads, and existing living shorelines, a docking facility
and boat ramp in section C l. There is also an existing bulkhead and docking facility in section
B. There are coastal wetlands along the entire shoreline,which consists mostly of Distichilis
spicata, Limonium carolinianum,Juncus roemerianus, Salicornia bigelovii, Scirpus acutus,
Spartina alterniflora,and Spartina patens on Queen Creek.
The Division of Water Resources classifies this area as SA/HQW Waters. This area of Queen
Creek is not designated as a Primary Nursery Area and is open to the taking of shellfish. Water
depths within this project location are -2'nlw/mlw to -3.5' nlw/mlw depending on location. The
bottom substrate is sand and some SAV were observed within the proposed sill area. A SAV
survey was completed by the applicant. Queen Creek is approximately 2,323 feet wide at this
location.
10. PROJECT DESCRIPTION:
The applicant is proposing to install 3,520 feet of living shoreline divided into 4 sections. The
4 sections are B (1,135 ft), Cl (1,150 ft), C2 (782 ft), and C3 (537 ft). According to my
calculations the entire sill will total to 3,604 feet.
Section B extends from the northern park boundary to the south portion of the 4H pier. The
applicant is proposing to install a living shoreline totaling 1,135 feet of combination QuickReef
and Natrx Sustainable ExoForms. This is proposed to have 10 sections with 9 gaps every 100 ft
that are each 5 feet long. 8 of the gaps would be overlapping baffles. The base width would be
6.7ft and 2ft in height. The landward edge of the sill would be no more than 30 ft from Normal
High Water. The water depths in this section are-2.2' to-3.4' at mhw.
Section Cl is located at the Hammocks Beach State Park visitor center and extends from the
existing dock to the existing 500' sill. The applicant is proposing to install a living shoreline
totaling 1,150 feet of combination QuickReef and Natrx Sustainable ExoForms. This is
proposed to have 10 sections with 9 gaps every 100 ft that are each 5 feet long. The gaps would
be overlapping baffles. The base width would be 6.7ft and 2ft in height. The landward edge of
the sill would be no more than 30 ft from Normal High Water. The water depths in this section
are -2.5' to -3.2' at mhw.
Section C2 is located at the northwestern terminus of the existing 500' sill to the bluff below
the existing Hickory Bluffs trail. The applicant is proposing to install a living shoreline totaling
Field Investigation Report: Hammocks Beach State Park-NC State Parks
DCM Major Permit
Page 13
782 feet of combination QuickReef and Natrx Sustainable ExoForms. This is proposed to have
7 sections with 6 gaps every 100 ft that are each 5 feet long. There would be a seventh gap at
the end of the existing sill and the beginning of this proposed sill separating Cl and C2. The
gaps would be overlapping baffles. The base width would be 6.7ft and 2ft in height. The
landward edge of the sill would be no more than 30 ft from Normal High Water. The water
depths in this section are -2.2' to -3.2' at mhw.
Section C3 is located at the bluff shoreline of the FFA camp. This sill would end south of a
small marsh channel. The applicant is proposing to install a living shoreline totaling 537 feet of
combination QuickReef and Natrx Sustainable ExoForms. This is proposed to have 5 sections
with 4 gaps every 100 ft that are each 5 feet long. The gaps would be overlapping baffles. The
base width would be 6.7ft and 2ft in height. The landward edge of the sill would be no more
than 30 ft from Normal High Water. The water depths in this section are -2.3' to -2.9' at mhw.
11.ANTICIPATED IMPACTS:
The proposed development would fill and usurp 23,584 ft2 of shallow bottom habitat. There
would be no filling of coastal wetlands or SAV.All portions would be at least 10'from any SAV.
The increase in suspended sediment and turbidity levels from the sill placement would be
temporary,occur while the sill placement is taking place and should be minimal given the bottom
composition. The proposed additions should not be a hindrance to navigation due to the fact all
portions would be located landward 1,305' from the USACOE channel setbacks. The proposed
development would also meet the minimum 15' setback from the riparian access lines and not
exceed a maximum distance of 36.7' waterward of NHW(includes base width).
