The C-1 area of coastal North Carolina lies in the southern portion of Onslow Bay in
the Atlantic Ocean. Shellfish production throughout C-1 is good, and both clams and
oysters can be harvested. Review of the sampling data for Area C-1 since the last
triennial survey of 2009 indicates little overall change in bacteriological water quality
since that time. Area C-1 is classified properly at this time, and no changes are
necessary.
1.0 SANITARY SURVEY
1.1 INTRODUCTION
Area C-1 is composed of all waters between the Intracoastal Waterway (ICWW)
Channel Marker #4 near Swan Point and ICWW Channel Marker #25 at Alligator
Bay. This includes the waters of Chadwick Bay, Fullard Creek, Bumps Creek,
Biglings Creek, Hell Gate Creek, Charles Creek, Alligator Bay, and Mill Creek.
The communities of Carrel Chapel, Peru, Swan Point, Chadwick Acres, and
North Topsail Beach, as well as a portion of Sneads Ferry, all border these
waters. Shellfish production throughout the area is considered good, and both
oysters and clams can be harvested. The area is commercially important in
regard to shellfish production.
Area C-1 contains approximately 3,955 total water acres (Figure 1). See Figure 2
for an area map and sampling station locations. Table 1 contains sampling
station descriptions.
1.2 SHORELINE SURVEY OF SOURCES OF POLLUTION
Survey Methods
A comprehensive shoreline survey of Area C-1 was completed in April, 2010.
Annual updates were completed in 2011 and 2012 as well. The purpose of the
evaluations is to identify actual and potential pollution sources that may
adversely impact the suitability of shellfish for consumption. The C-1 growing
area is bordered to the north by New River and Stump Sound to the south. The
growing begins at Swan Point and extends south to the Highway 210 Bridge at
North Topsail Beach.
North Topsail Beach is the only municipality in C-1. The remainder of the area
consists of unincorporated portions of Onslow County. Land uses within the
growing area are primarily agricultural and residential, however residential use is
predominant. The population estimate for the growing area is 2,987. This number
is based on census data from the year 2000. The current actual population is
likely higher than the census estimate. This is due to increases in residential
construction since 2000. Also of note, the growing area experiences significant
seasonal fluctuations in population. The census numbers may not account for
these yearly changes in population.
1
New actual and potential pollution sources for this survey were mapped using
GPS (Figure 3), and pollution source data were collected using Trimble’s sub-meter
GeoXT GPS receiver with EVEREST multipath rejection technology. Data
were collected in the SSF format using real-time corrections from the integrated
Wide Area Augmentation System receiver. The data were post-processed using
GPS Pathfinder Tools applications in order to get the most precise data.
Additionally, a Geographic Information System (GIS) was developed, including
pertinent information and digital pictures for each source.
Non-Point Source Pollution
Marinas – Marina facilities are evaluated during the shoreline survey because of
their potential to affect the suitability of adjacent shellfish waters for harvest
through inputs of both biological and chemical contaminants. A marina is defined
as “any water area with a structure (dock, basin, floating dock, etc.) which is
utilized for docking or otherwise mooring vessels and constructed to provide
temporary or permanent docking space for more than 10 boats” (15A NCAC 18A
.0901). The waters enclosed by a marina are classified as Prohibited for the
harvest of shellfish, and an additional area beyond the marina can also be
classified as Prohibited depending on the number of boat slips present. See
Figure 4 for marina locations and Table 2 for a summary of marina information.
Eleven marinas were evaluated in the C-1 growing area. The facilities are
evaluated to determine the current number of slips and to document the types
and sizes of vessels using the facility. Three of the marinas are located in waters
that are closed to the harvest of shellfish. Two of the dockage facilities surveyed
have only 10 slips and do not require a shellfish closure. The remaining marinas
have associated shellfish closures. The Hobart-Justice canal slip-count increased
to 84 slips. The current shellfish closure is based on 100 slips. The Chadwick
Acres canal slip-count has increased to 36. The current shellfish closure is based
on 50 slips. The remaining marinas saw little or no changes since the prior
survey.
Stormwater – Stormwater can adversely impact shellfish growing areas by
rapidly transporting bacteria and other contaminants from the land to the water
(Figure 5). Runoff from impervious surfaces, subdivisions, and other cleared or
developed land is a contributing factor to fecal coliform levels in the C-1 area. Mill
Creek and the creeks that drain into Chadwick Bay are the larger drainages in
the growing area. Although theses creeks are not particularly large, cumulative
effects of stormwater runoff from within the areas may be significant. The Mill
Creek drainage is of particular concern. Most of the new residential development
in the growing area can be found near Mill Creek and Alligator Bay. North Shore,
The Landing at Mill Creek, Millstone Landing and Mimosa Bay, are residential
developments that can impact Mill Creek and adjacent waters. Occurring prior to
2007, were increases in commercial development, primarily retail businesses,
along NC Highway 50 and Highway 172. Additional commercial growth during
2
the last three years has been minimal in this area. However, there is potential for
more growth of this type due to the availability of land and municipal water and
sewer along these corridors.
Subdivisions - Subdivisions are noted in the survey (Figure 6) as an indicator of
population growth, as well as for their tendency to concentrate potential sources
of pollution such as failing septic systems, animal wastes, and stormwater. On
this survey, aerial photography and GIS parcel data was used to determine the
location and extent of each subdivision. The Mill Creek area has seen the most
residential growth during the last three years. Three subdivisions in this area, Mill
Creek (The Landing, at Mill Creek), Millstone Landing and Mimosa Bay are
seeing significant increases in construction. Marine base expansions are likely
driving the demand for housing in the area. The three subdivisions have
municipal sewer service. Mimosa Bay has a few onsite wastewater systems.
However most of the homes in Mimosa Bay will be on a municipal wastewater
system. North Shore is another subdivision near Mill Creek. Growth has been
slower here than the newer residential development in this area. However there
are undeveloped lots within the subdivision as well as adjacent tracts of land, so
future growth can be expected. It is important to note that North Shore also has a
130 acre, 18-hole golf course. Tidewater on the Bay is located near Mimosa Bay.
The development was never completed, and is currently for sale. Future
redevelopment seems likely at some point. The tract is 383 acres and is situated
on the northeast side of Alligator Bay near Mill Creek.
Chadwick Shores, located near Chadwick bay, is a 510 lot subdivision with 279
homes documented at the time of this survey. Most of the waterfront lots are
developed, so growth will be primarily in the interior portions of the subdivision.
Increased demand for housing in the C-1 area will likely result in more new
homes in Chadwick Shores. The remaining subdivisions are primarily located on
North Topsail Beach, along the Intracoastal Waterway and in the vicinity of
Chadwick Bay. Growth during the last three years has been limited in all of these
subdivisions.
Onsite Wastewater – Homes along and in the vicinity of Chadwick Bay use on-site
systems to dispose of wastewater. Primarily, the remainder of the growing
area within the scope of this sanitary survey is served by municipal sewer. There
is one community subsurface wastewater disposal system in C-1(Figure 7). It is a
low pressure pipe system and it serves individual homes and condominiums in
the Bayshore Marina and Racquet Club community. The system appears to be
properly maintained. The groundcover is mowed and no surfacing effluent or
ponding of rainwater was noted during site visits. Inspections of other septic
systems in C-1 revealed no active failures. However, one owner had a previous
wastewater backup. Inspection of the drainfield and the perimeter of the property
revealed no surfacing effluent or illicit discharges. According to the owner, this
system was pumped and the problem ceased.
3
Municipal Wastewater Treatment Plants (WWTP) – At the time of the previous
C-1 Triennial Survey, there were three wastewater treatment facilities in the
growing area (Figure 7). The largest of these plants was the North Topsail
Utilities Plant. The facility is now owned and operated by Pluris, a company that
is based on the west coast, but operates systems across the country. The Pluris
facility provides sewer service for much of the C-1 area. The facility consists of
four lagoons and 180 acres of spray fields. The WWTP currently has a design
capacity of 874,000 gallons per day (gpd), and the average daily flow is typically
between 300,000 and 500,000 gpd. Chlorination is used for disinfection. Pluris
has applied for a new wastewater permit that will allow for an increase in their
treatment capacity. The new permit would include upgrades at the facility that will
provide a higher sewer treatment level. The new capacity will be > 1 mgd and the
treated effluent will be disposed of using infiltration basins or possibly a
combination of the basins and a portion of the existing spray fields.
Shellfish Sanitation staff accompanied NC Division of Water Quality (DWQ) staff
for a compliance inspection at the Pluris site on January 27, 2010. The lagoon
berms were being maintained properly and freeboard in the lagoons was within
an acceptable range. The chlorine contact chamber was cloudy. However the
effluent consistently exhibits acceptable chlorine residual levels. One deficiency
found at the site was the failure to establish a winter groundcover on the spray
fields. Ponding was evident in several low areas of the spray fields.
Inspection reports for the plant were reviewed in order to further evaluate the
facility’s compliance history. Records indicated periodic algae blooms in the
lagoons as well as algae in the chlorine contact chamber. The algae blooms tend
lower the pH and raise the total suspended solids (TSS) of the effluent. No spills
at the plant or in the collection system were reported during the three years prior
to the triennial survey in 2010.
During the annual survey in 2012, NC DWQ staff was accompanied for a startup
inspection at the Pluris regional wastewater plant. The facility has recently
completed phase I of a newly constructed wastewater treatment plant. It is
designed to produce effluent that meets or exceeds state and federal standards.
The plant utilizes membrane bioreactor (MBR) technology and currently has a
design capacity of .5 million gallons per day (MGD). Future expansion will include
an additional .5 MGD membrane filter which will increase the capacity to 1.0
mgd. Disinfection is achieved using UV light. The effluent passes through a dual
UV channel prior to release into high rate infiltration ponds. A subsurface
perimeter drainage system is used to lower the groundwater level at the ponds.
This system has been plumbed such that the collected groundwater can be
stored in an existing lagoon with the future intent of reuse purposes. If the
storage lagoon is full the groundwater will discharge to a 500 foot stormwater
type level spreader. During the period between April, 2010 and May 2012, no
sewer system overflows were reported. Additionally, no bacterial limit violations
were reported.

The other two wastewater facilities are package treatment plants that were built
to serve two new subdivisions. One of the developments was Tidewater on the
Bay, however the community was not completed and the plant was dismantled.
The other package plant was to serve a portion of Mimosa Bay, a nearby
subdivision. Due to low flow rates, this plant was never in operation. Initially
wastewater from Mimosa Bay was being stored in the upset lagoon at the
Mimosa Bay package plant. This was observed during an inspection of the
package plant. A pump and haul permit from NC DWQ had been applied for by
the operator, however it had not yet been approved. Pump and haul was
eventually approved as a temporary measure. A new sewer main has since been
constructed, and the wastewater from Mimosa Bay is now treated at the Pluris
facility. The new sewer collection system permit allows for 370 sewer tie-ins at
Mimosa Bay. At the time of the survey, the subdivision had 155 recorded lots.
Additional phases of development are planned, so the number of lots and
subsequent homes will increase. The package wastewater plant originally
constructed for Mimosa Bay is now inactive.
Shellfish Sanitation has documented forty-eight sewer lift stations within the
Pluris wastewater collection system in C-1 (Figure 7). All of the lift stations have
backup warning systems to notify the utility should a failure occur. However most
of the lift stations do not have a backup generator. Several of the pump stations
and portions of the collection system are located in close proximity to open
shellfish waters. One such area is the portion of North Topsail Beach that is
located along C-1. Additionally, there are portions of the Intracoastal Waterway
that are open to shellfishing and within close proximity of sewer collection
infrastructure. Timely sewer spill notifications would be particularly important for
these areas.
Wildlife and Domestic Animals – Habitat for deer and other mammals is
favorable along most of the C-1 growing area. Livestock within the growing area
is minimal. The Escoba Bay subdivision does have horse stables in a common
area within the community. The site is located along the upper reaches of
Charles Creek (Figure 8).
Areas of Concern / Poisonous and Deleterious Substances – A seasonal
campground at New River Marina was added to the database as an area of
concern (Figure 9). At the time of the survey the site had twenty-one campers.
The campers were connected to subsurface wastewater disposal systems. There
were no signs of septic system malfunctions during the site visit.
No sources of poisonous or deleterious substances were identified in the C- 1
growing area.

1.3 HYDROGRAPHIC FACTORS RESPONSIBLE FOR THE SPREAD OF
POLLUTION
Tidal movements in the C-1 area are primarily influenced by New River Inlet.
Salinities in the area are generally high, and ranged from 17 to 39 parts per
thousand (Table 8). Rainfall and the resultant runoff is the primary source of
transport for fecal coliform bacteria in the C-1 area.
Area C-1 is managed by a conditional area management plan. See Figure 2 for
conditional classifications. The waters of C-1 classified as Conditionally
Approved open are normally open to shellfish harvest. These waters are closed
when management plan criteria is exceeded. Temporary closures to shellfish
harvest occur after 1.5 inches of rain or greater in a 24-hour period. During the
time period of this report, portions of this area have been closed 39 times for a
total of 276 days. Six of these closures, totaling 58 days, were caused by
extremely heavy rainfall associated with Tropical Storm Hanna in September
2008, Tropical Storm Ida in November 2009, Tropical Storm Nicole remnants in
September 2010, Hurricane Irene in August 2011, Tropical Storm Beryl in May
2012 and Hurricane Sandy in October 2012. See Table 9 for a listing of
temporary closures in this area and Table 10 for samples collected prior to
reopening these areas.
Several rain gauge stations are used to monitor rainfall in the C-1 area. Average
monthly rainfall measured at one of the rain gauges in the area during the time
frame of this report was 3.49 inches (Table 11).
1.4 BACTERIOLOGICAL SURVEY OF SHELLFISH GROWING WATERS
The monitoring of Area C-1 adheres to the systematic random sampling strategy
outlined by the National Shellfish Sanitation Program (NSSP) and consists of 30
sample sets from 19 sampling stations (Figure 2).
The bacteriological survey covered for the preparation of this report included
water samples from 11/7/2007 through 10/10/12. During that time period, a total
of 570 water samples were collected during times that the waters were open to
the harvest of shellfish, and analyzed for fecal coliform bacteria in compliance
with the systematic random sampling regime. Table 12 lists, for each individual
sampling station, the date the sample was obtained, the tidal cycle upon which
the sample was taken, and ambient salinity. Fecal coliform Most Probable
Number (MPN) and summary statistics are listed as well.
Only one of the nineteen sampling stations currently exceeds approved NSSP
bacteriological standards. This station is located in an area that is closed to
shellfish harvest.

1.5 SUMMARY OF BACTERIOLOGICAL DATA ANALYSIS
A couple of stations in the Fullard Creek area have shown a slight decline in
bacteriological summary statistics since the last Sanitary Survey Report in 2009.
Stations #2 and #5A currently have estimated 90th percentiles of 25 and 23
respectively. At the time of the last report, the estimated 90th percentiles for these
two stations were 18 and 12 respectively. This is despite an apparent decrease
in the average monthly rainfall of 3.49” for this period versus 4.10” in the prior
period.
Station #17, located at the confluence of Mill Creek and Alligator Bay, is the only
current station to exceed approved bacteriological standards. The current
geometric mean is 14.55 and estimated 90th percentile is 86. This is compared to
a geometric mean of 17.33 and an estimated 90th percentile of 102 in 2009.
Refer to Table 13 for summary and descriptive bacteriological statistics.
1.6 OVERALL EVALUATION AND RECOMMENDATIONS
Classification of the C-1 area appears to be adequate. No changes in
classification are necessary at this time. The growing area will continue to be
monitored closely, and any required changes will be made as needed.
2.0 CONDITIONAL AREA MANAGEMENT PLAN
2.1 INTRODUCTION
Area C-1 is composed of the waters between the Intracoastal Waterway (ICWW)
Channel Marker #4 at Swan Point, and ICWW Channel Marker #25 at Alligator
Bay. Included in this area are Chadwick Bay, Fullard Creek, Bumps Creek,
Biglings Creek, Hell Gate Creek, Charles Creek, Alligator Bay, and Mill Creek.
The communities of Carrel Chapel, Peru, Swan Point, Chadwick’s Acres, West
Onslow Beach, and the southern portion of Sneads Ferry, are all included in the
area. The C-1 watershed comprises approximately 13 square miles and roughly
3,955 acres of water acres. Water quality in area C-1 is affected by rainfall, and
the resultant runoff. Shellfish production is considered good throughout the area,
and both oysters and clams can be harvested.
2.2 MANAGEMENT PLAN
The Conditionally Approved section of C-1 which is normally open to shellfishing
will be immediately recommended closed after 1.5 inches of rain within a 24 hour
period. The temporarily closed waters include the following:
All those waters bordered on the northeast by a straight line from Swan
Point through ICWW Channel Marker #4 to the eastern tip of West Onslow
7
Beach (south shore of New River Inlet), and bordered on the southwest by
the Surf City Bridge.
This closure line includes all waters in the B-9 and C-1 areas. These areas will
remain closed until such time as the rainfall event has ended and sampling
indicates that water quality meets approved area criteria.
Several rain gauge stations have been established within the B-9 and C-1 areas.
Monthly tally sheets are received by the Shellfish Sanitation Section from rain
gauge contacts. Rainfall amounts are checked by Shellfish Sanitation personnel
via telephone contact with rain gauge recorders or via the DMF Communications
Center to determine if temporary closures are needed.
In accordance with 15A NCAC 18A .0913, immediate closure of shellfish waters
to the harvesting of shellfish will be made in the event of a public health
emergency. A public health emergency means any condition that may
immediately cause shellfish waters to be unsafe for the harvest of shellfish for
human consumption.
2.3 IMPLEMENTATION OF CONDITIONAL AREA CLOSURE
If the level of rainfall in the management plan is exceeded, a proclamation is
issued for temporary closure of the conditionally approved area. The
proclamation is distributed by fax, email, mail, or by area law enforcement
officers who in turn distribute it to local establishments in the affected area for
public notification.
After hours and on weekends, Shellfish Sanitation personnel will be in contact
with the DMF Communications Center in Morehead City and the rain gauge
contacts for information regarding rainfall reports. The DMF Communications
Center is on duty 24 hours per day. If management plan criteria is exceeded, a
closure proclamation is issued.
2.4 PATROL OF CLOSED AREA
Patrol of shellfish harvesting areas is the sole responsibility of the Division of
Marine Fisheries Law Enforcement Section. For information regarding
enforcement of closures and patrol of closed areas, see the Patrol Policy of the
DMF Law Enforcement Section.
2.5 REOPENING CRITERIA
After the rainfall event has ended and sufficient time has elapsed to allow
shellfish to cleanse, the temporarily closed area will be sampled. If the results
indicate fecal coliform levels to be acceptable, a proclamation will be issued to
8
reopen the area. In accordance with 15A NCAC 113-221 of the DMF rules, a 12-
hour notification period is required for the reopening of closed shellfishing areas.
Changes to this management plan may be necessary as additional data is
collected. At the present time, a conservative approach will be taken with regard
to temporary closures with the interest of public health in mind.
3.0 CONDITIONAL AREA EVALUATION
3.1 INTRODUCTION
The National Shellfish Sanitation Program (NSSP) conditionally approved
classification for shellfish growing waters allows the utilization of valuable
shellfish resources by permitting harvesting when environmental conditions
cause fecal coliform levels to be satisfactory in areas that would otherwise be
closed to the harvesting of shellfish. In order for the State to be in compliance
with NSSP guidelines, conditionally approved areas must be evaluated yearly in
accordance with Model Ordinance, Chapter IV, @ 03, C., (3), (a) and (b) of the
NSSP Guide for the Control of Molluscan Shellfish. This report is intended to
comply with that portion of the NSSP yearly evaluation of the conditionally
approved portions of the Mill Creek Area, C-1, in Onslow County. Each of the six
required elements of the evaluation will be included in this report.
3.2 COMPLIANCE WITH MANAGEMENT PLAN CRITERIA
All rainfall events that exceeded the management threshold resulted in a closure
being made, with the possible exception of two events. On 5/21/08, calls were
made to the Town of North Topsail Beach rain gauge but no one was reached.
Neighboring rain gauges at Virginia Creek and Stump Sound were called and
reported rainfall amounts of 0.60” and 1.30”. It wasn’t until the monthly calendar
was received that a value of 1.75” for the North Topsail Beach rain gauge was
shown for that date.
On 1/17/10, calls were made to the Town of North Topsail Beach rain gauge but
no one was reached due to staff being off for the weekend. Accordingly,
neighboring rain gauges at Virginia Creek and Sneads Ferry were called and
reported rainfall amounts of 1.20” and 1.4”. It wasn’t until the monthly calendar
was received that a value of 1.5” for the North Topsail Beach rain gauge was
shown for that date.
A new station has been added in Chadwick Bay in order to increase the rainfall
information received. Online resources such as NOAA and other web based
products have been added to the monitoring regime, which will help provide
timely and accurate rainfall amounts in these cases. Additionally, rain gauge
contacts are asked to call in after exceeding the 24 hour threshold.
9
3.3 ADEQUACY OF REPORTING
During this survey period, there were a couple of possible issues with capturing
area rainfall events. These issues resulted, on two occasions, in closures not
being made despite rainfall events of greater than or equal to 1.5 inches. In
these cases, however, the rainstorms were very scattered and sporadic, with
neighboring rain gauges receiving less than 1.5 inches of rain. In order to reduce
these instances, internet based resources have been added to the monitoring
regime, and will be used to gain additional information on rainfall totals. A new
station in Chadwick Bay has also been added in order the rainfall coverage area.
3.4 COOPERATION OF PERSONS INVOLVED
The conditionally approved area concept is a cooperative effort involving the
Marine Patrol and Shellfish Sanitation Sections of the Division of Marine
Fisheries (DMF). The Shellfish Sanitation Section is responsible for monitoring
conditionally approved growing areas and developing management plans. Patrol
of shellfish harvesting waters and authority to open and close these waters is the
sole responsibility of the DMF Marine Patrol. The administrative procedures to
implement these actions are outlined in a memorandum of understanding
between the Division of Marine Fisheries and the Shellfish Sanitation Section.
No major problems have occurred with implementing the conditionally approved
area concept in North Carolina.
Rainfall information is gathered from various individuals throughout the state
including private citizens, DMF marine patrol and Shellfish Sanitation personnel.
Additional resources are used to determine the amount and locations of
precipitation, such as the NOAA National Weather Service precipitation website.
3.5 COMPLIANCE WITH APPROVED GROWING AREA CRITERIA
All stations currently located in the conditionally managed portions of Area C-1
fall well within the range for approved status, so no changes in classification are
necessary as a result of this report.
3.6 FIELD INSPECTION OF POLLUTION SOURCES
A comprehensive shoreline survey of Area C-1 was completed in April, 2010.
Additionally, annual updates were carried out in 2011 and 2012, in accordance
with the requirements of the NSSP Model Ordinance, Chapter IV @ .01C.
3.7 COLLECTION OF WATER SAMPLES
During the time period of this report, Area C-1 has been sampled in accordance
with the management plan criteria of the area as required by the conditionally
10
approved classification of the NSSP. Area C-1 adheres to the systematic
random sampling strategy outlined by the NSSP and consists of 30 sample sets
from each of 19 sampling stations located throughout the area.
3.8 SUMMARY
The conditionally approved area classification of the NSSP provides a way to
utilize a resource for direct market purposes that would otherwise only be
available for relaying or depuration purposes. Refinement of management plans
is continual and critical to assure that shellfish harvested from the conditionally
approved growing area are from waters that meet approved area criteria.
