RE: 401 Water Quality Certification - Requested Items DENR-WATER QUALITY
WETLANDS AND STORMWATER BRANCH
Ammons Mountain Properties, Inc.
Madison County, North Carolina
DWQ Project # 08-0675
Dear Mr. McMillan,
Please reference the "Approval of 401 Water Quality Certification" (Certification) dated
December 22, 2008 (Attachment A) sent by the North Carolina Division of Water Quality
(DWQ) in response to the permit application submitted by ClearWater Environmental
Consultants, Inc. (CEC), on behalf of Mr. Justus Ammons of Ammons Mountain
Properties, Inc. The Certification authorizes impacts associated with development of a
residential community with an amenity pond to be known as Traditions. In the
Certification, the DWQ requested the submittal of several additional items prior to
impacts occurring at the site. Each requested item will be discussed below.
Condition #10: "The minimum water release plan for the proposed dam must be
approved in writing by this Office before the approved impacts may occur. The plan
must include written explanation of the specific discharge rate and mechanism to provide
,for each required release. The plan must also include any design specifications, details
and calculations to show that the release shall be achieved in the given conditions. The
plan shall also include monitoring that ensures compliance. The plan and any associated
,facilities, once approved, must be in place and implemented upon the completion of the
dam."
The proposed dam design includes a 2" PVC low-flow release pipe. This pipe is
located as the base of the dam, along side the 12" drain. This pipe provides for
continuous flow through the dam regardless of the ponds water level. The low-
flow release pipe can be seen on the dam design drawings that have been included
for review (Figure 1). Water flow from the 2" PVC low-flow release pipe will be
approximately 0.19 cubic feet per second. Calculations used to determine flow
through the low-flow release pipe are attached for review (Attachment B).

Visual observations to ensure water is flowing through the pipe will be made at
each water quality sampling visit and each temperature logger download visit
(every two months); and reported in the annual water quality sampling report
(discussed below).
Condition #11: "The impoundment discharge should be monitored to ensure thermal
impacts to waters will not exceed the temperature standard for mountain streams. Unless
otherwise stipulated by the Division of Water Quality, discharge water temperatures
should be routinely monitored and compared to inflow water temperatures to ensure
compliance."
Upon completion of construction of the pond, CEC will install two Onset Tidbit
temperature data loggers (logger) below the outfall of the dam to record stream
temperatures. One logger will be placed immediately downstream of the pond
outfall the other will be placed 300 to 500 feet downstream of the outfall. Upon
completion of construction, the dam will impound the origins and headwaters of
the associated tributaries. Because of this, it is not possible to install loggers
upstream to monitor in-stream flow. The loggers will be monitored and
downloaded every two months to ensure they are in proper working order.
Temperature data will be submitted annually with the associated water quality
sampling report (discussed below).
Condition #12: "The discharge should be aerated to enhance dissolved oxygen levels."
The proposed dam design will provide for the aeration of water. Water will flow
into the cold water release inlet then travel through a 24" pipe and into a 2' by 8'
inlet box structure. Water will then flow across the top of the dam (and under a
small bridge) and cascade down the back of the dam. The back of the dam will be
reinforced with gabions which will be faced with rock revetments. Water
cascading down the rock revetment wall will become aerated before it reaches the
stream. Dam construction details are illustrated in the attached dam design
drawings (Figure 1).
Condition #16: "An impoundment sampling schedule and methodology must be finalized
before the proposed impacts may occur. The office recommends utilizing the attached
guidance document `Predictability Study Protocol for Sampling Reference
Impoundments' (NCDWQ, March 12, 2008)."
A "Water Quality Monitoring and Sampling Protocol" for the pond located within
the Traditions subdivision is attached for review (Attachment C). This study will
continue for a period of five years. Reports will be submitted annually to the
DWQ.
Condition #17: "Final design details for the dam and impoundment shall be submitted to
DWQ for approval in writing before the proposed impacts may occur. The final plan
shall include a discussion of how water quality standards will be monitored and
Mr. Ian McMillan

maintained within the impoundment. The final plan shall also include the structural
design drawings and details for the dam, including the plan and profile views illustrating
the height, toe, materials, spillway, as well as the operation and maintenance plan."
The dam includes a cold water release, a low-flow release pipe, and outfall
designed to aerate water released from the dam. The final dam design has been
attached for review (Figure 1). Water quality standards will be monitored for a
period of five years as outlined in the "Water Quality Monitoring and Sampling
Protocol" (Attachment C). The applicant is responsible for the operation and
maintenance of the dam and will follow the "Dam Operation, Maintenance, and
Inspection Manual 1985 (revised 2007)" developed by the NC Division of Land
Resources, Land Quality Section.
The information submitted in this package addresses all requests made in the Certification.
CEC believes the totality of this information allows DWQ to conclude that the applicant
has addressed recommendations in the letter. The applicant respectfully requests that the
DWQ approve the attached information so that construction may begin at the site.
Should you have any questions or comments concerning this project please do not hesitate
to contact me at 828-698-9800.

INTRODUCTION
On December 22, 2008, the NC Division of Water Quality (DWQ) issued an "Approval of 401
Water Quality Certification" (Certification) to Mr. Justus Ammons of Ammons Mountain
Properties, Inc. (the permittee). The permittee currently owns approximately 400 acres near Mars
Hill in Madison County, North Carolina and is proposing the development of a low-density
residential subdivision, known as Traditions, with approximately 200 lots, ranging from 1.08 to
4.21 acres. A site vicinity map is included for review (Figure 1). The permittee has also made
application to the US Army Corps of Engineers (Corps) for impacts associated with subdivision
infrastructure and development. As a part of the development, the permittee will be constructing a
small on-line pond (approximately 0.75 acres) on the northern portion of the property. A pond
location map is included for review (Figure 2). The proposed study outlined below will be done in
accordance with Condition 10 of the Certification and the North Carolina Division of Water
Quality, Wetlands and Stormwater Branch's "Predictability Study Protocol for Sampling Reference
Impoundments - DRAFT" (Protocol) dated February 28, 2008.
METHODOLOGY
The permittee and Clearwater Environmental Consultants, Inc. (CEC) developed this plan for
monitoring the water quality of the permitted pond upon completion of construction.
Sampling as outlined in the Protocol is planned to begin the week of August 3, 2009 at the
Traditions pond. If the pond has not been constructed by the week of August 3, 2009, sampling as
outlined in the Protocol will begin as soon as pond construction is complete. At the impoundment,
five sampling stations will be identified. During the first sample, latitude and longitude of each
station will be taken for use with topographic maps or GIS data. A summary of the general
locations of the sampling stations is as follows:
• Stations 1, 2, and 3 will be evenly spaced across the centerline of the impoundment (lentic);
• Station 4 will be located downstream and within 50 linear feet of the impoundment outfall
in the flowing (lotic) stream reach; and
• Station 5 will be located downstream and between 200 and 500 linear feet of the
impoundment outfall in the flowing (lotic) stream reach.
As a note, no upstream sample station will be identified. Upon completion of construction, the dam
will impoundment the headwaters and origin of the associated stream channels; therefore, there will
be no stream segments above the impoundment.
SAMPLING
Five water quality sampling stations will be established at the Traditions ponds as described above.
Water samples will be taken every other week during the growing season from the week of August
3, 2009 through the week of September 21, yielding 4 sample sets. Samples are divided into lotic
samples which include the samples and measurements taken at Stations 4 and 5; and lentic samples
which include samples and measurements taken at Stations 1, 2, and 3. Field measurements and
grab sample results will be recorded on data sheets taken from the DWQ's "Intensive Survey Unit
Standard Operating Procedures". The type of sample or measurement taken (field or grab) and
parameters measured are outlined below.
Lotic Samples (Stations 4 and 5)
o Field Measurements (taken 0.1m below the surface)
¦ temperature
¦ dissolved oxygen (% and mg/1)
¦ pH
¦ specific conductance
o Grab Samples (taken 0.1m below the surface at/near the thalweg)
¦ nutrients (total phosphorous, total Kjeldahl nitrogen, ammonia [NH3], nitrate +
nitrite [NO2+NO31, chlorophyll-a)
¦ turbidity
• Lentic Samples (Stations 1, 2, and 3)
o Field Measurements (taken 0.1m below the surface and at lm intervals to the lake bottom)
• temperature
¦ dissolved oxygen (% and mg/1)
¦ pH
¦ specific conductance
o Field Measurement (1 measurement reported at each sample location)
¦ Secchi depth transparency - reported value as the average of two measurements
o Grab Samples Using a LabLine (taken as spatial composites of the photic zone, defined as
twice the Secchi depth)
¦ nutrients (total phosphorous, total Kjeldahl nitrogen, ammonia [NH3], nitrate +
nitrite [N02+NO31, chlorophyll-a)
¦ turbidity
EQUIPMENT
The in situ field measurements (temperature, dissolved oxygen (% and mg/1), pH, and specific
conductance) will be taken using a Hydrolab Quanta. A Secchi disk will be used to measure the
water transparency at the three lentic stations across the centerline of the impoundment. All data
conforms to the "Standard Method for the Examination of Water and Wastewater" and EPA
methods.
In addition, Onset Tidbit temperature data loggers will be installed at both downstream stations at
the site to monitor water temperatures every two hours. These data loggers will provide precise
temperature ranges and can be easily downloaded in the field. Installation of the data loggers will
also satisfy Condition 11 of the Certification.
REPORTING
This study will be conducted for 5 years during August and September of the respective year.
Upon completion of the each year's study, CEC on behalf of the permittee will provide the DWQ
with a report summarizing all results and an electronic copy of all data.
