VI. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Over 97% of all the streams will not be impacted by the proposed Rroiects The design of the
golf course has been planned to incorporate streams and wetlands into the design of the golf
course as hazards The project has been planned to avoid perennial streams to the extent feasible
except for unavoidable road crossings Permanent impacts to streams wetlands are limited to
road crossings and to prepare the site The site~lan was adjusted to the extent feasible to cross
creeks at strai hg t segments and are as perpendicular as feasible. Abridge is proposed over a
perennial stream and Dutchman's Creek There are no proposed direct discharges into any
stream Plunge pools are proposed at small golf course discharges to decrease velocity over the
buffers adjacent to streams.
Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that maybe appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed. If mitigation is required for this project, a
copy of the mitigation plan must be attached in order for USACE or DWQ to consider the
application complete for processing. Any application lacking a required mitigation plan or
NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to
review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream
Work in North Carolina, available at htt~://h2o.enr.state.nc.us/ncwetlands/strm~*,ide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
Page 7 of 10

preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Impacts are limited to two road crossings and minor wetland impacts. Almost 97% of all streams and
wetlands are preserved. The overwhelming majority of the remaining wetlands and streams are
preserved within common open space and/or along rear or side property lines.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the

Dutchmans Creek Wastewater Treatment for Reclaimed Water
Introduction
Wastewater collection and on-site treatment are proposed for the entire Dutchmans
Creek development, which will initially consist of approximately 375 single family
residences, a clubhouse with restaurant, swimming, tennis and other amenities. The
development will include a golf course that will afford an opportunity to reuse the treated
wastewater for irrigation. The developers desire to promote a "green concept" for the
Dutchmans Creek community, and the beneficial reuse of wastewater will be a key
feature of their master planning and marketing programs.
The treatment technology we plan to use will meet the limits of 10 ppm BOD and 5 ppm
TSS, and turbidity less than 10 NTU. The b+eleg+sal treatment system will be the
Advantex trickling filter system as manufactured by Orenco, Inc., followed by tertiary
sand filters and UV disinfection. Tablet type chlorinators will be installed for redundancy
on the disinfection. Constant monitoring of the effluent turbidity will be provided, with
automatic diversion to the reject pond if the 10 NTU limit is exceeded.
Irrigation Areas
Fully treated wastewater will be discharged to the reclaimed water holding pond, The
treated wastewater will not be enough by itself to meet the irrigation demand for the golf
course. The total maintained grass area (the "playable surfaces") will be approximately
150 acres, and additional areas of roughs and common areas can be added that can be
used for disposal areas during the wet weather months when the fairways and greens
may not need irrigation
Process Narrative
The design approach that we propose for the Dutchmans Creek will comply with the
15A NCAC 02T .0900 Rules for Reclaimed Water Systems, and the treated wastewater
will be used by the irrigation system for the golf course. The sewer collection system
will be a Septic Tank Effluent Pumping (STEP) system followed by a recirculating
aerobic trickling treatment process, tertiary filtration, and ultraviolet and chlorine
disinfection. The STEP collection system and Recirculating Aere~is Treatment Units will
be products of Orenco Systems, Inc., based in Sutheriin, Oregon. Orenco has an
established successful history in manufacturing components for these types of on-site
systems, and has an excellent reputation for research and development in small
community wastewater systems. They maintain their own technical engineering staff
that assists with and reviews the design of projects using their equipment, and they will
not furnish equipment for systems that they cannot approve. The following narrative
describes the basic concept:

e
Each single family residence will have its own "interceptor tank" that pumps to the
collection system. The "interceptor tank" is basically a septic tank that has a pump and
filter chamber at one end. The raw sewage enters the tank via a standard riser
assembly, and as it flows across the tank, solids settle to the bottom, and scum and
grease rise to the top. The water that enters the pump and filter basin can only enter
from the intermediate "clear" zone that is at the approximate halfway depth in the tank.
A set of tubular plastic filters prevent any solids larger than '/-inch from reaching the
pump chamber. The filters also provide a substrate for micro-organisms that further
reduce the strength of the wastewater. Depending on the flowrate, 40% to 60% of the
BOD can be removed in the interceptor tank.
Because the solids have been removed, small multi-stage vertical turbine submersible
pumps can be used to pump the effluent. These pumps are usually '/2 or 3/
horsepower, and have low flow -high head characteristics. The pretreated effluent
from the interceptor tanks is pumped through small diameter plastic piping to the
treatment units. The pipe can be PVC or HDPE, and will be buried with at least 30
inches cover. It is anticipated that the largest size needed for a trunk main will be 4-inch
diameter.
The discharge pumps are controlled by float switches that connect to a control panel for
each tank. The control panel is typically mounted on the exterior foundation wall of the
building served by the pumps, and has audio and visual alarms for high water level and
pump failure. The floats will be set to provide 24 hours emergency storage in the
interceptor tanks in case of power outage.
For smaller clustered units such as the cottages and villas, and for commercial buildings
such as retail shops and offices, one interceptor tank may serve more than one building.
Tanks can be furnished in different sizes, and the usual criteria would be to limit the
velocity across the cross sectional area to 1 ft. per minute. For larger users, such as
the restaurant and clubhouse, two tanks in series may be used. Grease traps will be
required for all commercial kitchen facilities.
The treatment system would be the Orenco Advantex system. The process is
fundamentally the same as a recirculating sand filter (RSF), except that instead of a
sand bed, the wastewater trickles over s sheets of synthetic textile fabric that hang
vertically in fiberglass enclosures. The synthetic fabric supports more biomass per
cubic foot than a sand filter, and because the fabric is suspended in air, more oxygen is
available to the aerobic micro-organisms. If higher strength waste is present, blowers
can be added to increase the oxygen transfer rate. (reference technical literature from
Orenco provided in the Appendix). Typically, blowers are not sized to provide a
calculated oxygen transfer rate, but ventilation fans are used to keep fresh air moving
through the treatment pods.
Just as with an RSF, the wastewater from the STEP collection piping first enters a
recirculation tank at the head of the treatment works. At this point, the fresh wastewater
has virtually no solids or grease, and the BOD is usually less than 140 ppm. The fresh

~. i
wastewater mixes with the water already in the tank, which has already passed through
the Advantex units a number of times. A usual design recirculation ratio is 4:1. In
actual practice, the recirculation ratio will normally be higher due to the fact that the
development will rarely be 100% occupied or produce wastewater flows as high as the
estimated demands. This will result in less odor and lower BOD, but may require the
operator to add lime to the recirculation tank periodically. The water leaving the
Advantex units will have concentrations of both BOD and TSS less than 5 ppm. A
diverter float valve (RSV-Recirculating Spliter Valve) in the return line to the
recirculation tank will control whether treated effluent is discharged. If the recirculation
tank is not full, then the return flow from the treatment units will go into the tank to be
recycled again thus continuing to "polish" and reduce the strength of the wastewater. If
the recirculation tank is full, then the return flow will go to final filtration, disinfection and
discharge.
Following the b+etegisal- initial treatment process, the wastewater will be pumped
through a pressure sand filter. The pressure filter will be a conventional backwashable
pressure filter, as manufactured by the Neptune Benson company of Warwick, Rhode
Island. The filters will have a filtration rate of less than 4 gpm per square foot of filter
area, and the backwash will be returned to the reject pond and then back to the head of
the treatment system.
Disinfection will consist of Ultraviolet Light, with tablet chlorinators
for redundancy.
The treated effluent will be very high quality and will meet all of the requirements for
Reclaimed Water. Although the turbidity limit could not be guaranteed by the b+eleQi~at
treatment process alone, it is very likely that it will be achieved, and that the tertiary
filters will be very lightly loaded.
The fully-treated disinfected effluent will be discharged to the reclaimed water holding
pond, which is sized for 30 days storage capacity. This water will be used for irrigation
of the golf course. The irrigation requirements are much higher than could be satisfied
solely by the treated wastewater, and the plan is to construct one or two holding ponds
that will be filled by withdrawal from a stream on the property. The irrigation pumping
system will be designed to take water from either the reclaimed water holding pond, or
the creek water holding pond, but not both at the same time. (Note: I recommend that
you put that the reclaimed water will be used only during the hours of 6 PM -6AM for
additional public awareness)
Modular Expansion
The Dutchmans Creek project will likely be expanded to include new commercial areas
and future additional development. For this reason, the wastewater treatment system is
designed to exceed the initial demands. The system is designed to be expanded in a
modular fashion, with new biological treatment systems added as the demands increase
with build-out. The treatment system as designed will have a capacity of 300,000

ti.
gallons per day, but will have area for more treatment modules if needed. All that will
be required for future expansion is the construction of additional holding ponds.
