Water Resources
Permitting Section
Pilot Environmental, Inc. (Pilot) is pleased to submit this report addressing Step 1 of the
Engineering Alternatives Analysis (EAA) for the approximate 1.41 acre tract located south of U.S.
Highway 65 West in Walnut Cove, Stokes County, North Carolina.
Background
The National Pollution Discharge Elimination System (NPDES) permit program, created in 1972
by the Clean Water Act (CWA), helps address water pollution by regulating point sources that
discharge pollutants to waters of the United States. Under the CWA, EPA authorizes the NPDES
permit program to state, tribal, and territorial governments, enabling them to perform many of
the permitting, administrative, and enforcement aspects of the NPDES program. In states
authorized to implement CWA programs, EPA retains oversight responsibilities. The permit
provides two levels of control: technology -based limits and water quality -based limits (if
technology -based limits are not sufficient to provide protection of the water body).
Congress passed the Endangered Species Act (ESA) in 1973. The purpose of the ESA is to protect
and recover imperiled species and the ecosystems upon which they depend. It is administered
by the U.S. Fish and Wildlife Service (USFWS) and the Commerce Department's National Marine
Fisheries Service (NMFS). The USFWS has primary responsibility for terrestrial and freshwater
organisms, while the responsibilities of the Commerce Departments NMFS are mainly marine
wildlife. Under the ESA, federally protected species may be listed as either endangered or
threatened. "Endangered" means a species is in danger of extinction throughout all or a
significant portion of its range. "Threatened" means a species is likely to become endangered
within the foreseeable future. All species of plants and animals, except pest insects, are eligible
for listing as endangered or threatened. For the purposes of the ESA, Congress defined species
to include subspecies, varieties, and, for vertebrates, distinct population segments.

Pilot Project 4199
January 9, 2019
Scope of Services
Based on our understanding, an Engineering Alternatives Analysis (EAA) is required with any
NPDES application for a new or expanding wastewater treatment plant discharge, in accordance
with 15A NCAC 2H.0105(c)(2). Pilot has been requested to address Step 1 of the Engineering
Alternatives Analysis Guidance Document.
The site is an approximate 1.41 acre tract located south of U.S. Highway 65 West in Walnut Cove,
Stokes County, North Carolina. The site includes the parcel identified by the Stokes County
Geographic Information System (GIS) website as Parcel Identification Number (PIN) 6952-61-
8937. Pilot understands that the applicant proposes to complete an EAA for the proposed
discharge of treated wastewater from the property at a point identified with coordinates
36.277180, -80.163920. Our scope of services included a field reconnaissance, interviews and a
review of available literature to address Step 1 of the Engineering Alternatives Analysis Guidance
Document. The site boundary was not marked at the time of our field evaluation.
Literature Review
We reviewed the U.S. Geological Survey (USGS) Topographic Map, the U.S. Department of
Agriculture (USDA) Soil Survey of Stokes County and the U.S. Fish and Wildlife Service (USFWS)
National Wetland Inventory (NWI) Map.
• The USGS Topographic Map (Drawing 1) depicts an unnamed tributary to Old Field Creek
(Redbank Creek) along the southern site boundary. Other surface waters or wetlands are not
depicted on the site. A structure is depicted on the northern -central portion of the site.
• The USDA Web Soil Survey of Stokes County (Drawing 2) identifies the following soil mapping
units on the site: Clover sandy clay loam (CoB2) and Clover fine sandy loam (CfC). The Clover
series consists of well drained, moderately permeable soils that occur on low hills. The soil
mapping units are not identified on the Stokes County Hydric Soils List.
Pilot also reviewed the last published USDA Soil Survey of Stokes County (Drawing 2A). The
published soil survey depicts an unnamed tributary to Old Field Creek along the southern site
boundary, generally consistent with the USGS Topographic Map. Other surface waters or
wetlands are not depicted on the site.
• The USFWS NWI Map (Drawing 3) depicts a riverine feature along the southern site boundary,
generally consistent with the USGS Topographic Map. Other surface waters or wetlands are not
depicted on the site.
• Pilot reviewed the FEMA FIRM (Drawing 4) for the site. The FEMA FIRM identifies the site within
Zone X, areas outside the 100-year floodplain (area of minimal flood hazard).

Limited Engineering Alternatives Analysis
Pilot Project 4199
January 9, 2019
Field Reconnaissance
Pilot personnel conducted the site visit on December 17, 2018. The site is developed with a multi -
residential apartment building and an associated gravel/asphalt-paved parking lot. The
remainder of the site consists of wooded land and a maintained grassed lawn.
The wooded land consists of approximately 50-year old mixed hardwoods and with scattered
Ioblolly pines. The overstory vegetation includes tulip poplar, Ioblolly pine, American beech,
shagbark hickory, black cherry, eastern red cedar and red maple trees. The understory
vegetation is moderately dense and includes saplings similar to species found in the overstory
and musclewood, Chinese privet, Christmas fern, ebony spleenwort, Japanese honeysuckle,
Japanese stilt grass, green brier, onion grass and poison ivy vines.
The proposed project consists of the discharge of wastewater from the on -site apartment
building to a stream located along the southern portion of the site. The stream has defined beds
and banks, evidence of an ordinary high-water mark, substrate sorting and meanders. Based on
our observations, the stream is perennial. The banks of the stream appear to be slightly eroded
with evidence of sediment in the stream bed. Photographs of the site are included as
attachments.
Step 1 Considerations
Zero Flow Stream Restrictions
Pilot contacted Mr. Curtis Weaver with the USGS to inquire about the flow regime of the stream
associated with the discharge point of the proposed project. According to Mr. Weaver, a separate
investigation was previously conducted by the USGS on the unnamed tributary to Old Field Creek
(Redbank Creek) that is located along the southern site boundary. According to Mr. Weaver, the
unnamed tributary to Old Field Creek (Redbank Creek) is estimated to be zero flow for the 7 day, 10
year (7Q10) and 30 day, 2 year (30Q2) annual discharge estimates. Because the 30Q2 and 7Q10
flows are both estimated to be zero, no new or expanded (additional) discharge of oxygen
consuming waste shall be allowed. Requirements for existing discharges to streams where the 30Q2
and 7Q10 flows are both estimated to be zero shall be determined on a case -by -case basis. A copy
of the e-mail correspondence from Mr. Weaver is included as an attachment.
Receiving Stream Classification Restrictions
The site is located in the Roanoke River Basin. An unnamed tributary to Old Field Creek (Redbank
Creek) is located on the southern portion of the site. The NCDEQ DWR has classified Old Field Creek
(Redbank Creek), the receiving waters, as Class B waters. In accordance with 15A NCAC 2B .0200,
based on the surface water classification, residential and industrial wastewater discharges are
allowed.

Basinwide Water Quality Plans
The site is located in the Upper Dan River Sub -Basin, part of the Roanoke River Basin, Hydrological
Unit Code (HUC) 03010103. According to the 2012 Roanoke River Basinwide Water Quality Plan,
five segments of the Dan River and the Smith River are listed as Impaired waters due to fecal
coliform bacteria, turbidity, biological integrity or copper within the sub -basin. According to the
Roanoke River Basin Basinwide Assessment Report, Old Field Creek (Redbank Creek), the
receiving waters of the site, was not included in the assessment. Town Fork Creek, the receiving
waters of Old Field Creek (Redbank Creek), was assessed for fish communities and were graded
as 'good' in the 2004 and 2009 assessments. Based on our review of the basinwide water quality
plan, we did not identify permitting strategies that may limit wastewater discharges to particular
streams within the basin due to lack of stream assimilative capacity.
Impaired Waters and Total Maximum Daily Loads (TMDLs)
Pilot reviewed the NCDEQ-DWR Water Resources Data, Statistics and Maps interactive TMOL
Watersheds and Impaired Waters Map websites. According to the TMDL Watersheds interactive
website, the site is located in an area identified as Haw River, Deep River, Third Fork Creek, and
Dan River Turbidity and Fecal Coliform TMDL. According to an EPA report (Total Maximum Daily
Load for Turbidity and Fecal Coliform for Haw River, Deep River, Third Fork Creek and Dan River
in North Carolina, EPA Approved date January 11, 2005), applicable water quality standards for
discharge into Class C or WS-IV waters must not exceed set values. The turbidity of discharge
may not exceed 50 nephelometric turbidity units (NTU) and fecal coliform should not exceed a
geometric mean of 200 per 100 milliliters per 5 consecutive samples examined during a 30-day
period nor exceed 400 per 100 milliliters in more than 20 percent of the samples examined. The
report does not identify TMDL values for Class B waters.
The Impaired Waters Map does not identify Old Field Creek (Redbank Creek) or Town Fork Creek
as Impaired Waterson the 303(d) list and/or subject to impending TMDLs that may have
wastewater discharge restrictions. Old Field Creek (Redbank Creek) is identified as Category 3 —
No Data Available and Town Fork Creek is identified as Category 2 — Sustaining.
Presence of Endangered Species
The project location was entered into the USFWS Information for Planning and Conservation
(IPaC) online mapping system to obtain a resource list of threatened and endangered species and
designated or proposed critical habitat that may be affected by the project. The IPaC Resources
Trust Report is included as an attachment. Additionally, the USFWS Endangered Species Database
was reviewed to identify federally protected threatened and endangered species in Stokes
County, North Carolina. The following federally protected threatened and endangered species
were identified:

Northern Ions -eared bat (Myotis septentrionalis)
Description: The northern long-eared bat is a medium-sized bat about 3 to 3.7 inches in length
but with a wingspan of 9 to 10 inches. As its name suggests, this bat is distinguished by its long
ears, particularly as compared to other bats in its genus, Myotis, which are actually bats noted
for their small ears (Myotis means mouse -eared). The northern long-eared bat is found across
much of the eastern and north central United States and all Canadian provinces from the Atlantic
coast west to the southern Northwest Territories and eastern British Columbia. The species'
range includes 39 states. White -nose syndrome, a fungal disease known to affect bats, is
currently the predominant threat to this bat, especially throughout the Northeast where the
species has declined by up to 99 percent from pre -white -nose syndrome levels at many
hibernation sites. Although the disease has not yet spread throughout the northern long-eared
bat's entire range (white -nose syndrome is currently found in at least 22 of 39 states where the
northern long-eared bat occurs), it continues to spread. Experts expect that where it spreads, it
will have the same impact as seen in the Northeast.
Habitat: During summer, northern long-eared bats roost singly or in colonies underneath bark,
in cavities, or in crevices of both live and dead trees. Males and non -reproductive females may
also roost in cooler places, like caves and mines. This bat seems opportunistic in selecting roosts,
using tree species based on suitability to retain bark or provide cavities or crevices. It has also
been found, rarely, roosting in structures like barns and sheds. Northern long-eared bats spend
winter hibernating in caves and mines, called hibernacula. They typically use large caves or mines
with large passages and entrances; constant temperatures; and high humidity with no air
currents. Specific areas where they hibernate have very high humidity, so much so that droplets
of water are often seen on their fur. Within hibernacula, surveyors find them in small crevices or
cracks, often with only the nose and ears visible.
Conclusion: Hibernacula was not observed on the site. The site contains wooded land that could
afford suitable summer roosting habitat. Similar habitat was observed on surrounding
properties. Based on a review of the June_1_2016_NLEB_HUC12 NLEB shapefiles obtained from
the Raleigh Ecological Services Field Office website, the 12 digit HUC with the nearest confirmed
hibernation and/or maternity sites is located more than 91 miles from the site. Based on the
distance to known roost trees, the limited area of suitable habitat and availability of similar
5

suitable habitat, we have made the determination that the proposed project is not likely to
adversely affect this species.
Roanoke logperch (Percina rex)
Description: The Roanoke logperch is a large darter (up to 165 millimeters (mm) total length) with
8-11 vertical lateral blotches, dark green "worm -like" markings interspersed between dorsal
saddles, speckled fins with the first dorsal fin having an orange band (particularly vivid in males),
and a bulbous snout.
Habitat: Roanoke logperch typically inhabit medium -to -large sized warm, clear streams and small
rivers of moderate to low gradient. Adults usually occupy riffles, runs, and pools containing sand,
gravel, or boulders that are free of silt. Young -of -year congregate in mixed -species schools in
shallow habitat underlain by sand and gravel along stream margins.
Spawning occurs in April or May in deep runs over gravel and small cobble, and logperch typically
bury their eggs with no subsequent parental care. Larval drift is likely an important dispersal and
recolonization mechanism. Roanoke logperch mature at 2-3 years of age and commonly live five
to six years.
Roanoke logperch actively feed during the warmer months by utilizing their snout to overturn
gravel to forage on benthic aquatic macroinvertebrates. Generally, the logperch exist in low -
density populations.
Conclusion: Suitable habitat for the Roanoke logperch is not located on the site. Therefore, we
have made a determination of no effect for this species.
James spinvmussel (Pleurobema collinal
Description: The James spinymussel is a small freshwater mussel slightly less than three inches in
length. Adults have a dark brown shell with prominent growth rings and occasionally, short spines
on each valve. Young mussels have a shiny yellow shell with or without one to three short spines.
Like other freshwater mussels, this species is a filter feeder. It feeds on plankton collected from
water that is passed over its gills. Reproduction occurs sexually. Females carry eggs in their gills.
During spawning, the male releases sperm into the water column and the sperm is taken into the
female through the gills. The resulting larvae (known as glochidia) are released from the female
into the water column and must attach to a fish host to survive. While attached to the fish host,
development of the glochidia continues. Once metamorphosis is complete, the juvenile mussel
drops off the fish host and continues to develop on the stream bottom. Known fish hosts for this
species include the bluehead chub (Nocomis leptocephalus), rosyside dace (Clinostomus
funduloides), blacknose dace (Rhinichthys atratulus), mountain redbelly dace (Phoxinus oreas),
rosefin shiner (Lythrurus ardens), satinfin shiner (Cyprinella analostana), central stoneroller
(Campostoma anomalum), and swallowtail shiner (Notropis procne).

Limited Engineering Alternatives Analysis
Pilot Project 4199
January 9, 2019
Habitat: Suitable habitat for this species includes free -flowing streams with a variety of flow
regimes. The James spinymussel is found in a variety of substrates that are free from silt.
Conclusion: Suitable habitat for the James spinymussel is not located on the site. Therefore, we
have made a determination of no effect for this species.
Schweinitz's sunflower (Helianthus schweinitzii)
Description: Schweinitz's sunflower is a perennial that regularly grows approximately 6.5 feet tall
(though it can be shorter if young or injured) and can occasionally reach heights of 16 feet. It has
thickened roots that are used by the plant to store starch. The stem is purplish in color, and the
upper third bears secondary branches at 45-degree angles. The leaves are arranged in pairs on
the lower part of the stem but usually occur singly (or alternate) on the upper parts. Leaves are
attached to the stem at right angles, and the tips of the leaves tend to droop. The leaves are thick
and stiff, with a rough upper surface. The upper leaf surfaces have broad spiny hairs that are
directed toward the tip and soft white hairs cover the underside. The plant produces small yellow
flowers from late August until frost. This species is able to colonize through the dispersal of seeds
that readily germinate without a dormant period.
Habitat: Schweinitz's sunflower occurs in full to partial sun and is found in areas with poor soils,
such as thin clays that vary from wet to dry. It is believed that this species once occurred in natural
forest openings or grasslands. Many of the remaining populations occur along roadsides.
Conclusions: Suitable habitat for Schweinitz's sunflower is not located on the site. Therefore,
we have made a determination of no effect for this species.
Small-anthered bittercress (Cardamine micranthera)
Description: A slender, erect perennial herb with fibrous roots and one (rarely more) simple or
branched stem(s), growing up to 4 dm tall, that produce white flowers in April and May. The
basal leaves are 1 to 5 cm long (occasionally longer), 0.5 to 2.0 cm wide, crenate, with one (rarely
two) pairs of small lateral lobes or leaflets. Stem leaves are alternate and mostly unlobed, 1 to
1.5 cm long, crenate and cuneate. The flowers are subtended by leafy bracts, have 4 white petals,
6 stamens, and small round anthers. Fruit is a silique, 0.8 to 1.2 cm long and approximately 1 mm
in diameter, with a beak 1 to 1.2 mm long.
Habitat: Small-anthered bittercress is found in seepages, wet rock crevices, stream banks,
sandbars, and wet woods along small streams, in fully to partially -shaded areas.
Conclusion: Suitable habitat for the small-anthered bittercress is not located on the site.
Therefore, we have made a determination of no effect for this species.

Conclusions and Opinions
Step 1 of the EAA has been completed in accordance with the North Carolina Department of
Environmental Quality (NCDEQ) Division of Water Resources (DWR) Guidance. A summary of our
findings is bulleted below.
• Zero Flow Stream Restrictions — Regulation 2B .0206 states that existing discharges to
zero -flow streams should be handled on a case -by -case basis. For many years, permits
for the existing discharges to so-called "zero -flow stream" did not contain any special
requirements. However, since 1990, three different requirements have been somewhat
randomly placed in NPDES permits. These requirements are:
1. Require an alternatives analysis be done and give summer limits of 5 mg/L (BODs) and
1 mg/L (NH3-N) and winter limits of 10 mg/L (BODs) and 1.8 mg/L (NH3-N) after a
three-year period, if the discharge continued.
2. Require an alternatives analysis to meet the above limits, but renew the permit
without a change in limits (i.e., no 3-year compliance schedule to meet limits) during
that permit cycle.
3. Require an alternatives analysis to meet summer limits of 5 mg/L BODs) and 2 mg/L
(NH3-N) and winter limits of 10 mg/L (BODs) and 4 mg/L (NH3-N) without a change in
limits during that permit cycle.
• Receiving Stream Classification Restrictions - In accordance with 15A NCAC 2B .0200,
based on the surface water classification, residential and industrial wastewater discharges
are allowed.
• Basinwide Water Quality Plans - Based on our review of the basinwide water quality plan,
we did not identify permitting strategies that may limit wastewater discharges to
particular streams within the basin due to lack of stream assimilative capacity.
• Receiving Stream Classification Restrictions - In accordance with 15A NCAC 2B .0200,
based on the surface water classification, residential and industrial wastewater discharges
are allowed.
• Impaired Waters and Total Maximum Daily Loads (TMDLs) - The site is located in an area
identified as Haw River, Deep River, Third Fork Creek, and Dan River Turbidity and Fecal
Coliform TMDL. Applicable water quality standards for discharge into Class C or WS-IV
waters must not exceed set values. The turbidity of discharge may not exceed 50
nephelometric turbidity units (NTU) and fecal coliform should not exceed a geometric
mean of 200 per 100 milliliters per 5 consecutive samples examined during a 30-day
period nor exceed 400 per 100 milliliters in more than 20 percent of the samples
examined. The Impaired Waters Map does not identify Old Field Creek (Redbank Creek)
or Town Fork Creek as Impaired Waters on the 303(d) list and/or subject to impending
8

Limited Engineering Alternatives Analysis
Pilot Project 4199
January 9, 2019
TMDLs that may have wastewater discharge restrictions. Old Field Creek (Redbank Creek)
is identified as Category 3 — No Data Available.
• Presence of Endangered Species - It is not likely for the proposed project to impact
federally listed threatened/endangered species. Agency concurrence of our opinions has
not been obtained. If agency concurrence of the conclusions made in this report for
threatened and endangered species is required for the proposed project, it will be
necessary to submit a request to the USFWS to determine if there are known populations
of federally protected threatened and endangered species on the site or nearby
properties.
In addition to addressing Step 1 of the EAA, Pilot contacted Mr. John Hennesy with the NCDEQ
NPDES Compliance and Expedited Permitting Staff. Mr. Hennesy informed us that the EAA as
part of the Individual Permit Application should be submitted to his office.

Subject: Response from USGS concerning...Re: [EXTERNAL] Zero/Low Flow Stream Estimate
Ms. Carston,
In response to your inquiry about the low -flow characteristics (7Q10, 30Q2, average annual discharge) for an unnamed tributary to Old
Field Creek near Walnut Cove in southeastern Stokes County, the following information is provided:
Upon pre-scoping the low -flow request you submitted last week, it came to my attention that your point of interest (lat/long
coordinates 36.277180, -80.163920 via email dated December 13, 2018) is almost identical to an upstream location on the same
stream for which a separate low -flow request was submitted on July 31, 2018. A visual examination using online aerial imagery indicates
the two points of interest are about 300 feet from each other (see screen shot below).
A basin delineation completed using the online USGS StreamStats application for North Carolina
(http:j/water.usgs.gov/osw/streamstats/north carolina.html) indicates the drainage area for the point of interest (36.27721, -80.16388
NAD83) is about 0.08 sqmi.
Forwarded at the end of this email is the response to the low -flow request for the upstream point of interest. Because
of the nearly identical location for the two points of interest, the low -flow characteristics that were determined for the
upstream point of interest are considered applicable to your point of interest. In short, the 7Q10 discharge is estimated
to be zero flow. Given the presence of the underlying Triassic basin geologic unit combined with the uncertainty
associated with low -flow discharges less than 0,05 cfs, the 30Q2 discharge is also estimated to be zero flow. Please see
the forwarded email for more information.

Mr. Weaver,
As I explained on the phone, I am working on some due diligence for an Environmental Alternatives Analysis and am
trying to figure out the zero/low flow estimate at my discharge point in Walnut Cove, Stokes County, NC. The
coordinates of the discharge point are 36.277180, -80.163920. Our discharge point is connected to an unnamed
tributary to Old Field Creek. Please let me know if you have any questions or if you need anything else to complete
your estimate.
Thank you very much for your assistance!

Mr. Creed,
In response to your inquiry about the low -flow characteristics (7Q10, 30Q2, average annual discharge) for an unnamed tributary to Old
Field Creek near Walnut Cove in southeastern Stokes County, the following information is provided:
A check of the low -flow files here at the USGS South Atlantic Water Science Center (Raleigh office) does not indicate a previous low -flow
determination for the point of interest, as identified by the lat/long coordinates (36.277, -80.163) provided in your email dated July 31,
2018. However, low -flow characteristics have been estimated at nearby locations within the Old Field Creek basin based on transfer of low -
flow characteristics from nearby partial -record and continuous -record sites within or near the basin.
No USGS discharge records are known to exist for the point of interest.
In the absence of site -specific discharge records sufficient for a low -flow analysis, estimates of low -flow characteristics at ungaged locations
are determined by assessing a range in the low -flow yields (expressed as flow per square mile drainage area, of cfsm) at nearby sites where
such estimates have previously been determined.
A basin delineation completed using the online USGS StreamStats application for North Carolina
(http://water.usgs.gov/osw/streamstats/north carolina.html) indicates the drainage area for the point of interest (36.27749, -80.16301
NAD83) is 0.07 sqmi.
For streams in southeastern Stokes County, low -flow characteristics published by the USGS are provided in the following reports:
(1) The first is a statewide report completed in the early 1990's. It is USGS Water -Supply Paper 2403, "Low -flow characteristics of streams
in North Carolina" (Giese and Mason, 1993). An online version of the report is available at http://pubs.usgs.gov/wsp/2403/report.pdf. The
report provides the low -flow characteristics (based on data through 1988) via regional relations and at -site values for sites with drainage
basins between 1 and 400 sqmi and not considered or known to be affected by regulation and/or diversions.
(2) The second is a basin -wide report for the Roanoke River basin published in 1996. It is USGS Water -Resources Investigations
Report 96-4154, "Low -flow characteristics and profiles for selected streams in the Roanoke River Basin, North Carolina"
(Weaver, 1996). An online version of the report is available through http://pubs.er.usgs.gov/publication/wri964154. The report
provides the low -flow characteristics (based on data through 1994) for continuous -record gaging stations and partial -record sites
within the Roanoke basin. The report also provides low -flow discharge profiles (7Q10, 30Q2, winter 7Q10, and 7Q2) for the
reaches of Dan River and Roanoke River in North Carolina as well as selected tributaries within the basin.
(3) The third is a statewide report published in March 2015. It is USGS Scientific Investigations Report 2015-5001, "Low -flow characteristics
and flow -duration statistics for selected USGS continuous -record streamgaging stations in North Carolina through 2012" (Weaver,
2015). The report is available online at http://pubs.usgs.gov/sir/2015/5001/. The report provides updated low -flow characteristics and
flow -duration statistics for 266 active (as of 2012 water year) and discontinued streamgages across the state where a minimum
of 10 climatic years discharge records were available for flow analyses.
3

Inspection of the Roanoke River basin -wide report indicates the presence of four (4) selected nearby USGS partial -record sites (4) in close
proximity of the point of interest where low -flow characteristics were published AND for which part or all of the basin is underlain by
the Triassic basin geologic unit. From a hydrologic perspective, streams underlain by this geologic unit have very little to no potentials for
sustained base flows during extended dry periods. At sites underlain by the Triassic basin where the USGS has collected sufficient records
for low -flow analyses, the low -flow characteristics for sites having drainage areas that would typically be expected to have sustained flows
actually have some of the lowest low -flow estimates in the State.
Among these 4 sites, the low -flow discharge yields for the indicated flow statistics are as follows:
Annual 7Q10 low -flow yields ==> 0 cfsm (7Q10 zero flow at all 4 sites)
Annual 30Q2 low -flow yields ==> from 0.19 to 0.29 cfsm (average about 0.24 cfsm, median about 0.23 cfsm)
Average annual discharge yields ==> 1.2 cfsm
Application of the above range in yields to the drainage area (0.07 sqmi) for the point of interest results in the following estimated low -flow
discharges:
Annual 7Q10 discharges ==> 0 cfs
Annual 30Q2 discharges ==> from 0.01 to 0.02 cfs (average about 0.01 cfs, median about 0.02 cfs)
Average annual discharge ==> about 0.08 cfs
Given the presence of the underlying Triassic basin geologic unit combined with the uncertainty associated with low -
flow discharges less than 0.05 cfs, it would be reasonable to round clown the estimated 30Q2 discharge to zero flow.
Please note the estimated flows are provided in units of cubic feet per second (cfs).
Please understand the information provided in this message is based on a preliminary assessment and considered provisional, subject to
revision pending further analyses.
Hope this information is helpful.
Thank you.

Project Name: Highway 65 West
November 29, 2018
Subject: List of threatened and endangered species that may occur in your proposed project
location, and/or may be affected by your proposed project
To Whom It May Concern:
The attached species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and fmal designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. Although not required by
section 7, many agencies request species lists to start the informal consultation process and begin
their fulfillment of the requirements under section 7(c) of the Endangered Species Act (Act) of
1973, as amended (16 U.S.C. 1531 et seq. ).
This list, along with other helpful resources, is also available on the U.S. Fish and Wildlife
Service (Service) Asheville Field Office's (AFO) website: https://www.fws.gov/raleigh/species/
cntylist/nc_counties.html. The AFO website list includes "species of concern" species that could
potentially be placed on the federal list of threatened and endangered species in the future. Also

New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could require modifications of these lists.
Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act,
the accuracy of the species lists should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website or the AFO website (the AFO website dates each
county list with the day of the most recent update/change) at regular intervals during project
planning and implementation for updates to species lists and information. An updated list may be
requested through the ECOS-IPaC system by completing the same process used to receive the
enclosed list or by going to the AFO website.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a Biological
Evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12 and on our office's website
at https://www.fws.gov/asheville/htmis/project_review/assessment guidance.html.
If a Federal agency (or their non-federal representative) determines, based on the Biological
Assessment or Biological Evaluation, that listed species and/or designated critical habitat may be
affected by the proposed project, the agency is required to consult with the Service pursuant to
50 CFR 402. In addition, the Service recommends that candidate species, proposed species, and
proposed critical habitat be addressed within the consultation. More information on the
regulations and procedures for section 7 consultation, including the role of permit or license
applicants, can be found in the "Endangered Species Consultation Handbook" at: http://
www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF.
Though the bald eagle is no longer protected under the Endangered Species Act, please be aware
that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16
U.S.C. 668 et seq.), and projects affecting these species may require additional consultation (see
https://www.fws.gov/southeast/our-services/permits/eagles/). Wind energy projects should follow
the wind energy guidelines (http://www.fws.gov/windenergy/) for minimising impacts to
migratory birds (including bald and golden eagles) and bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://

We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in

The birds listed below are birds of particular concern either because they occur on the USFWS
Birds of Conservation Concern (BCC) list or warrant special attention in your project location.
To learn more about the levels of concern for birds on your list and how this list is generated, see
the FAQ below. This is not a list of every bird you may find in this location, nor a guarantee that
every bird on this list will be found in your project area. To see exact locations of where birders
and the general public have sighted birds in and around your project area, visit the E-bird data
mapping tool (Tip: enter your location, desired date range and a species on your list). For
projects that occur off the Atlantic Coast, additional maps and models detailing the relative
occurrence and abundance of bird species on your list are available. Links to additional

Probability Of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project
activities to avoid or minimize impacts to birds. Please make sure you read and understand the
FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before using or attempting
to interpret this report.
Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) your
project overlaps during a particular week of the year. (A year is represented as 12 4-week
months.) A taller bar indicates a higher probability of species presence. The survey effort (see
below) can be used to establish a level of confidence in the presence score. One can have higher
confidence in the presence score if the corresponding survey effort is also high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in
the week where the species was detected divided by the total number of survey events for
that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee
was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is
0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of presence
in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12
(0.25) is the maximum of any week of the year. The relative probability of presence on
week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
Breeding Season ( )
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across
its entire range. If there are no yellow bars shown for a bird, it does not breed in your project
area.
Survey Effort (I)
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the l0km grid cell(s) your project area overlaps. The number of
surveys is expressed as a range, for example, 33 to 64 surveys.
No Data (—)
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe

11/29/2018
Event Code: 04EN1000-2019-E-00182 3
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on
all years of available data, since data in these areas is currently much more sparse.

Migratory Birds FAQ
Tell me more about conservation measures I can implement to avoid or minimize impacts
to migratory birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize
impacts to all birds at any location year round. Implementation of these measures is particularly
important when birds are most likely to occur in the project area. When birds may be breeding in
the area, identifying the locations of any active nests and avoiding their destruction is a very
helpful impact minimization measure. To see when birds are most likely to occur and be breeding
in your project area, view the Probability of Presence Summary. Additional measures and/or
permits may be advisable depending on the type of activity you are conducting and the type of
infrastructure or bird species present on your project site.
What does IPaC use to generate the migratory birds potentially occurring in my specified
location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern
(BCC) and other species that may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian
Knowledge Network (AKN). The AKN data is based on a growing collection of survey. banding.,
and citizen science datasets and is queried and filtered to return a list of those birds reported as

11/29/2018 Event Code: 04EN1000-2019-E-00182 4
occurring in the 10km grid cell(s) which your project intersects, and that have been identified as
warranting special attention because they are a BCC species in that area, an eagle (Eagle Act
requirements may apply), or a species that has a particular vulnerability to offshore activities or
development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your
project area. It is not representative of all birds that may occur in your project area. To get a list
of all birds potentially present in your project area, please visit the E-bird Explore Data Tool.
What does IPaC use to generate the probability of presence graphs for the migratory birds
potentially occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data
provided by the Avian Knowledge Network (AKN). This data is derived from a growing
collection of survey, banding, and citizen science datasets .
Probability of presence data is continuously being updated as new and better information
becomes available. To learn more about how the probability of presence graphs are produced and
how to interpret them, go the Probability of Presence Summary and then click on the "Tell me
about these graphs" link.
How do I know if a bird is breeding, wintering, migrating or present year-round in my
project area?
To see what part of a particular bird's range your project area falls within (i.e. breeding,
wintering, migrating or year-round), you may refer to the following resources: The Cornell Lab
of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of
interest there), the Cornell Lab of Ornithology Neotropical Birds guide. If a bird on your
migratory bird species list has a breeding season associated with it, if that bird does occur in your
project area, there may be nests present at some point within the timeframe specified. If "Breeds
elsewhere" is indicated, then the bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern
throughout their range anywhere within the USA (including Hawaii, the Pacific Islands,
Puerto Rico, and the Virgin Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation
Regions (BCRs) in the continental USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on
your list either because of the Eagle Act requirements (for eagles) or (for non -eagles)
potential susceptibilities in offshore areas from certain types of development or activities
(e.g. offshore energy development or longline fishing).
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made,
in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC

11/29/2018
Event Code: 04EN1000-2019-E-00182 5
species of rangewide concern. For more information on conservation measures you can
implement to help avoid and minimize migratory bird impacts and requirements for eagles,
please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species
and groups of bird species within your project area off the Atlantic Coast, please visit the
Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides
birds that may be helpful to you in your project review. Alternately, you may download the bird
model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical
Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic
Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use
throughout the year, including migration. Models relying on survey data may not include this
information. For additional information on marine bird tracking data, see the Diving Bird Study
and the nanotag studies or contact Caleb Spiegel or Pam Loring.
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid
violating the Eagle Act should such impacts occur.
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a Iist of all birds in your project area, only a subset of
birds of priority concern. To leam more about how your list is generated, and see options for
identifying what other birds may be in your project area, please see the FAQ "What does IPaC
use to generate the migratory birds potentially occurring in my specified location". Please be
aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that
overlap your project; not your exact project footprint. On the graphs provided, please also look
carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no
data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey
effort is high, then the probability of presence score can be viewed as more dependable. In
contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of
certainty about presence of the species. This list is not perfect; it is simply a starting point for
identifying what birds of concern have the potential to be in your project area, when they might
be there, and if they might be breeding (which means nests might be present). The list helps you
know what to look for to confirm presence, and helps guide you in knowing when to implement
conservation measures to avoid or minimize potential impacts from your project activities,
should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell
me about conservation measures I can implement to avoid or minimize impacts to migratory
birds" at the bottom of your migratory bird trust resources page.

NC Highway 65 Apartments
Narrative Description of Project
and the
Proposed Waste Water Treatment System Improvements
NC Highway 65 apartments is an existing small apartment complex that includes five (5)
(24'x32') two (2) bedroom apartment units. The facility is located in the southeast region of
Stokes County, at 1539 NC Hwy. 65, Walnut Cove, NC 27052. Until recently, the facility was
permitted to Mr. Dennis Bracy under General Permit NCG550000 (NC Highway 65 Apartments
WWTP Certificate of coverage NCG550709). As of December 29, 2017 the new property owner
is Mr. Ralph W. Nickerson of Nickerson Enterprises, LLC. The existing waste water treatment
system for the facility includes two (2) 1,000 gallon septic tanks, buried single pass sand filter,
and tablet chlorinator.
Mr. Dennis Bracy (previous owner) received Notice of Violation (NOV) (NOV-2017-PC-0612)
dated September 18, 2017 for a failing waste water treatment system at the subject property. The
NOV was based upon an inspection on September 12, 2017 (see attached) by Mr. Patrick
Mitchell, with NCDEQ — WSRO. Billingsley Septic Tank Company, acting operator of the
WWTP, contacted our firm, Hugh Creed Associates, Inc., P.A. to assist in the design of a new
waste water treatment system for the facility.
According to the NOV, the original certificate of Coverage NCG55709 for this facility was
issued for a maximum daily flow of 1,000 gallons per day (GPD). NCDEQ indicated in the NOV
that the facility includes five (5) two (2) bedroom apartments, which according the NC
Administrative Code 02T, the estimated flow is 1,200 GPD (i.e. 10 bedrooms at 120 GPD per
bedroom). Based on this information, our firm contacted Mr. Billingsley, with Billingsley Septic
Tank Company, and requested that a,water meter be installed on the well water system to obtain
daily water use data. Based on the water use data provide, (see attached data), the facility is using
far less than 1,000 GPD. It is our opinion, based on discussions with the operator, that the
existing buried single pass sand filter failed due to age, and the lack of maintenance due to lack
of access. Based on the flow data provided by the operator, on behalf of the owner, we are
questing that the facility continue to be permitted under General Permit NCG550000.
The proposed waste water treatment system improvements will include abandoning the existing
buried single pass sand filter, installing a new 2,000-gallon septic tank following the two (2)
existing 1,000-gallon septic tanks, a Bio-Microbics MicroFast 0.75fixed media aeration
treatment system, tablet chlorinator, and a tablet de -chlorinator.

BID-DYNRMIC'
TABLET FEEDER
GENERAL SPECIFICATIONS
The contractor shall furnish and install one Bio-Dynamic tablet feeder with all applicable equipment
as described in the following specifications. It shall be a flow rated proportional feeder that
allows for long-term unattended operation while providing a stable, adjustable chemical dose.
Treatment of the water or wastewater flow shall be accomplished by immersion of feed tubes
containing vertically stacked chemical tablets. Chemical agents shall be released as the liquid
erodes the tablets. The tablet feeder shall be equipped with a self -draining flow channel to allow
complete dry down of the chemical tablets during low and/or no flow conditions and to insure
long-term tablet integrity.
Principal items of equipment and components of the tablet feeder shall include an integral
one-piece molded inlet hub, inlet baffle, tiered flow deck including inert drainage tier, intermediate
flow tier and upper flow tier, stationary feed tube insert, feed tubes (2 or 4), outlet weir with
optional sluice, hydrodynamic mixing chamber and integral one-piece molded outlet hub. Liquid
or gaseous systems requiring extensive handling and safety procedures or dry chemical feeders
requiring separate drop boxes, or manholes for in -line mounting shall not be considered for
this application.
EQUIPMENT MANUFACTURER
The equipment specified herein shall be the product of a manufacturer having a minimum of
seven years experience in the construction of water and/or wastewater treatment systems and
equipment. Bids shall be prepared on the basis of the equipment and material specified herein
for purposes of determining the low bid. This is not done, however, to eliminate other products
or equipment of equal quality and efficiency. If equipment is to be substituted, approval of such
substitution must be made prior to execution of any order. It is assumed that substitution will
result in a reduction of cost to the contractor and that if accepted, these savings will be passed
along by a reduction in the base bid.

510-' YNRMIC®
CONSTRUCTION AND OPERATING CONDITIONS
The Bio-Dynamic tablet feeder shall be constructed of heavy duty, UV rated, rotationally molded polyethylene for maximum
strength and durability. The feeder shall be a complete dry chemical dosing system that allows dosage capability ranging from
1 to 50 mg/L, according to the operational flow rating (GPD) of the system. A peak flow factor of four shall be used for non -flow
equalized wastewater applications to insure proper dosage. The tablet feeder shall be elliptical in shape to utilize the velocity
and energy of the liquid for consistent chemical application. The system shall be supplied as a self -enclosed unit suitable for
direct burial without the need for a secondary manhole or enclosure.
The integral one-piece molded inlet and outlet hubs shall allow direct in -line connection to standard treatment system piping
without the need for special adapters or mounting fixtures. Four reinforced mounting feet shall be molded into the body of
the tablet feeder to allow the unit to be directly bolted to tankage or mounting brackets. All feeders shall be equipped with
molded in place trim lines located at six inch vertical increments. The trim lines shall accommodate installation of the feeder
and risers at the proper operational depth and yet allow field adjustment of the lid location to accommodate landscaping or
other functional considerations.
Each translucent ClearCheck feed tube shall contain a vertical stack of tablets which dispense chemical agents into the liquid
flow as the tablets are eroded. The chemical feed tubes shall be secured by retaining rings molded into the bottom of the flow
deck and with a stationary insert. The retaining rings and stationary insert shall be designed to eliminate the possibility of tube
displacement during high flow periods. Direct burial systems utilizing one or more 24" riser assembly shall include extension
handles permanently installed on each feed tube. The tablet feeder shall be designed with an internal slope for self -drainage
during low and/or no flow conditions to allow complete dry down of chemical tablets. Fall through the tablet feeder from inlet to
outlet shall be one inch.
INLET HUB AND BAFFLE
All flow entering the tablet feeder shall pass through the integral one-piece molded inlet hub and be channeled under an
adjustable inlet baffle. The molded inlet hub shall allow direct acceptance of (4" or6") Schedule40 PVC piping. The inlet baffle
shall be located so that the bottom of the baffle is positioned below the mean liquid level. The baffle shall be configured to
minimize the effect of periodic flow surges and optimize the dissolution pattern of the chemical tablets. It shall be held in place
by molded slots in the feeder sidewall. The baffle shall maintain chemical dosage during low flow periods, while regulating
chemical dosage during high flow periods.

FLOW DECK
The feeder shall contain a multi -tiered flow deck molded into the bottom of the system and configured to control liquid velocity
within the unit. The configuration shall result in a stable chemical dose throughout the operating range of the unit and eliminate
the potential for tablet degradation. The flow deck shall consist of three separate tiers designed to optimize the intrinsic energy
of the liquid. The lowest tier functions as the inert drainage tier and shall encompass all chemical feed tubes and traverse the
length of the feeder. This tier shall be employed during extremely low or no flow conditions to form a drainage channel for inert
particles and eliminate tablet swelling. Feed tube retaining rings shall be molded into the inert drainage tier and shall securely
locate each feed tube in position. When the flow rate increases up to three gallons per minute, the liquid level shall rise to the
intermediate tier. This tier is hyperbolic in shape and traverses the length of the feeder. The intermediate channel shall increase
flow velocity to insure accurate and consistent chemical delivery and to reduce or eliminate tablet wicking. At flow rates greater
than three gallons per minute, the liquid level shall rise to the upper tier of the unit. This tier shall result in uniform flow velocity
and provide adjustable tablet dissolution and consistent chemical dosage throughout the anticipated operating range.
STATIONARY INSERT
Retaining ribs shall be molded into the system housing to support a stationary insert. The insert shall be installed above the
solids drainage tier of the tablet feeder and traverse the area of the flow deck. Feed tubes and internal components shall be held
in proper position by the insert. Tapered locating holes shall be incorporated into the insert for ease of feed tube installation and
removal. For direct burial applications, drill points shall be provided in the feeder body and the stationary insert shall be
permanently affixed to the feeder body with synthetic drive rivets.
CHEMICAL FEED TUBES
The tablet feeder shall be equipped with one-piece translucent CiearCheck feed tubes. Each feed tube shall be equipped with
a twist lock cap for safety. Notches molded into the feed tube body shall prevent accidental cap removal. The feed tubes shall
utilize tablets with the nominal weight and dimensions of 5 ounces, 25/8" diameter and 13/16" height. The bottom of each feed tube
shall be integrally molded with the tube body and contain two drainage ribs to allow the flow stream to purge inert particles and
accomplish dry down of chemical tablets during no flow periods. The liquid shall flow through six equally spaced openings in
each feed tube for contact with the chemical tablets.

TABLET FEEDER
ADJUSTABLE OUTLET SLUICE
The tablet feeder shall be equipped with an optional adjustable outlet sluice to allow regulation of the liquid static head within the
unit and provide precise control over chemical dosage. The adjustable outlet sluice shall provide a one inch to three inch
adjustable outlet width. Sluice operation shall permit precise adjustment of the chemical dosage throughout the operating
range. Adjustment shall be made by rotating the molded plastic hex nut located at the top of each outlet sluice. The hex nut
shall protrude through the stationary insert to allow for adjustment from grade with a standard socket. The right and left sections
of the adjustable outlet sluice shall be synchronized by integrally molded gears. Each gear segment shall include adjustment
limits to insure that the sluice will operate within the desired design range. Each adjustable sluice shall include a top mounted
opening indicator. The indicator will provide the operator with a visual indication of the sluice position and the engraved scale on
the stationary insert shall indicate the sluice opening in inches. To provide operational flexibility, the adjustable outlet sluice
should always be used when an access riser is installed.
INTERNAL TUBE WITH RISER - SERIES 2000-5
FIXED WEIR
INTERNAL TUBE WITH RISER - SERIES 4000-S
The tablet feeder shall have a fixed weir with interchangeable 1 ", 2" and 3" plates. The weir plates shall induce a static head
within the feeder which regulates the quantity of tablets exposed to the liquid. The fixed weir plates shall be secured by molded
slots located within the feeder that allow plates to be removed and exchanged without the need to take the system off-line or the
need to make contact with the liquid stream. The molded slots facilitate interchangeability of weir plates and eliminate the need
f .adhesives or external fasteners. Alternating the fixed weir plates shall allow adjustment of the chemical feed dose in three
irate 20% fixed adjustment increments.

SPECIFICATIONS
HYDRODYNAMIC MIXING CHAMBER AND OUTLET HUB
The tablet feeder shall be designed with a hydrodynamic mixing chamber downstream of the outlet weir to induce a turbulent
flow prior to discharge. The hydrodynamic mixing chamber shall use the induced turbulence of the outlet weir or sluice to
provide thorough mixing of the chemical. The chamber is designed to hydrodynamically eliminate the laminar flow induced
upstream by the multi -tiered flow deck and prevent flow from short circuiting the treatment process. The integral one-piece
molded outlet hub shall directly accept (4" or6") Schedule 40 PVC piping. Systems that require separate drop boxes or outlet
adapters increase installation costs and shall not be considered for this application.
ACCESS RISERS
To provide maximum installation flexibility and eliminate the need for confined space entry equipment, optional riser assemblies
shall be provided. Adjustable access risers will allow direct burial of the tablet feeder and will accommodate direct connection
to existing system piping. Each riser shall be molded polyethylene with a nominal height of 24" and adjustable in 6" vertical
increments via trim lines molded into each riser section. Risers shall utilize the same molded cover as the tablet feeder body.
Each riser section shall contain transverse reinforcing struts and synthetic drive rivets at each joint to allow for direct burial. The
reinforcing struts shall be constructed of fiberglass reinforced plastic with a 1" outside diameter and molded nylon couplings on
each end. Each strut shall be held in position by an integrally molded retaining boss. Molded drill points shall be provided to
locate the drive rivets in the riser assembly. One tube of Bio-Dynamic sealant shall be supplied with each riser section and shall
be used to seal each riser joint internally and externally to insure watertight integrity.

BIO-SANITIZER® CHLORINATION TABLETS
The Bio-Dynamic tablet feeder shall be furnished complete with a (10 Ib., 25 Ib., 45 Ib. or 100 Ib.) supply of
Bio-Sanitizer disinfecting tablets. Bio-Sanitizer disinfecting tablets shall be manufactured and tested to
insure efficient and dependable disinfection for wastewater treatment system effluent and other applications
where a predictable long-term source of chlorine is desirable. The dissolve rate of the tablets shall generally
lower overall chemical use and provide for consistent control of chlorine residual. The tablets shall
be manufactured from pure calcium hypochlorite and contain at least 70% available chlorine. The tablets shall
incorporate beveled edges to enhance the chemical dissolution pattern and minimize wicking and jamming.
Each tablet within the feed tube shall be 25/a" diameter, compressed to a 13/16" thickness, weigh approximately
5 ounces and be white in color for easy identification. All flow through the system shall contact the
Bio-Sanitizer tablets. The tablets shall dissolve slowly, releasing controlled amounts of chlorine for water or
wastewater disinfection. The chlorine dosage rate shall be automatic and flow dependent. Periods of high
flow shall expose more tablets to the liquid passing through the system and during periods of low flow, fewer
tablets shall be exposed. The chemical application rate of the tablets shall remain consistent at peak flow
factors as high as four.
BIO-NEUTRALIZER® DECHLORINATION TABLETS
The Bio-Dynamic tablet feeder shall be furnished complete with a (25 Ib. or 45 Ib.) supply of Bio-Neutralizer

DELIVERY INSPECTION
The FAST® system has been designed and inspected to meet stringent quality assurance standards prior to shipment. Check the
packaging for signs of shipping damage before and after uncrating the unit. If there is evidence of damage or abuse, notify Bio-
Microbics, Inc. at [phone] or [phone].
About FAST°: The FAST® (Fixed Activated Sludge Treatment) system uses naturally occurring bacteria (biomass) to
treat sewage for dispersal into the environment. This continuous process provides the biomass with waste (food) and air in a
suitable environment. Dead bacteria and non -biodegradable waste settle and accumulate in the bottom of the septic tank for
periodic removal.
The FAST® process consists of the treatment module and blower. The blower provides air to the system via the air supply pipe.
The air supply pipe and draft tube create an air lift. The air lift mixes oxygen and waste throughout the media inside the tank.
Bacteria grows on the media and digests the waste. A vent pipe expels harmless vapors created by the process.

46,4,4 ,�:: ,rt Only qualified service personnel should open access pods and/or covers to a septic tank. Infectious organisms exist in a septic tank If any contact with
• °,i; ! ' _ wastewater occurs, immediately wash and disinfect all exposed areas and contact personal physician. Failure to do so could result in severe sickness or death.
D0 NOT use an open flame or cause a spark near a septic tank's access points. Gases emanating from septic tanks can explode if ignited or deadly if inhaled.

ACAUTION
Always have all Wilily lines and equipment marred by a locating service prior to performing any work. Failure to do so could result in severe bodily injury or
death.
FAST® systems may be located in the same position relative to the house and water supply as any conventional septic system.
However, some basic guidelines should be followed:
1. The FAST® system lid is designed to withstand a burial depth of up to 3 feet (0.9 meters). Do not place the tank in a location
where it could be subjected to traffic or additional weight. A professional engineer should be consulted if additional loading
conditions are expected. FAST® with feet option should be considered.
2. The FAST® system must be located so that sufficient slope (z2%, '% inch/foot) is provided for the influent and effluent lines.
3. Excessive back pressure must not be placed on the blower, Follow all installation guidelines.
4. The method and arrangement for effluent discharge must not interfere with the treatment plant's operation.

the module using supplied self -tapping screws. Creating
lateral stability for the FAST system is also recommended
by use of non -corrosive materials.
NOTE: If legs are >18" [45.7 cm] in length then Sch 80
PVC or stronger pipe must be used. Consult factory to
extend legs >36" [90 cm].
2. Attach leg
extensions to the base of the tank with stainless steel
anchor bolts (not provided). Two anchor bolts are
required per leg extension. Place the anchor bolts in the
corners opposite each other.

Insert 4" Sch 40 PVC pipe for use as an effluent line. Insert through tank wall and into
4" outlet gasket in the liner. Push pipe to baffle stops.

Numerous options exist for proper venting. Three of the most common are mentioned here. The
vent system must be sized properly to avoid excessive back pressure in the system (see table
below). It also must not allow surface water to enter the system and must allow intemal
condensation to drain.
DIRECT VENT
DIRECT VENT: The 6" o/v port can have holes drilled in it or a slotted cap put on it. Any cap must be
fastened with screws to prevent unauthorized access. The opening(s) should prevent foreign material from
entering the system.
REMOTE VENT: Branch off of the 6" o/v port or manhole below grade. Run the vent pipe to the desired
location and terminate above grade. Cover opening with #4 mesh screen or similar. Water accumulating in
the vent piping MUST be drained to prevent back pressure. NOTE: The vent should not exceed 100 ft.
[30.5m] in total length.
BIOFILTER: Please contact Bio-Microbics for guidance on how to build this buried vent.
NOTE: A biofilter vent must not allow moisture back into the treatment system.

(see chart). A "quick disconnect" is highly recommended to be installed at
this location. Blower piping to FAST® may not exceed 100 ft [30.5 mj total length
and have s 4 elbows. Keep all debris out of air line.
4. to the blower at the blower junction box. Be
sure to follow the supplied wiring diagram for the voltage at your specific location.
All blowers are dual voltage and must be connected according to the proper
diagram. Blower diagrams can be found on the blower's shipping box and/or at the
end of this manual.

ACAUTION
Always have all utility lines and equipment marked by a locating service prior to performing any work.
All electrical work shall be properly performed by a qualified electrician per all applicable codes. Failure to do so may result in severe bodily injury or death.
All FAST® system electrical parts are ETL (UL equivalent) certified for safety. The control panel meets NEMA4X standards for all
weather use (not explosive or submerged environments).
1. Examine wiring directions inside the supplied FAST® control panel
2. A dedicated breaker is required in the building's master electrical panel. Make connections between the master panel and
FAST® control panel.
3. Make connections between blower and FAST® control panel per the electrical diagram.
Bio-Microbics manufactures control panels that control UV systems and sewage pumps. The TRACK system (or other auto -
dialer) can also be connected to the panel.

It is the responsibility of the installer to ensure that the tank will not float due to hydraulic conditions at the site. Your local FAST®
Systems distributor may provide installation inspection services. If you have questions, call Bio-Microbics at 800-753-FAST
(3278) or [phone].
Ahvays secure all access covers to prevent unauthorized people from entering the tank. Only qualified service personnel should open access ports andior
. covers. infectious organisms exist in a septic tank. If any contact with wastewater occurs, immediately wash and disinfect all exposed areas and contact
personal physician. Failure to do so could result in severe sickness or death. DO NOT use an open flame or cause a spark near a septic tank's access points. Gases emanating from septic
tanks can explode if ignited or deadly if inhaled.
BEFORE THE UNIT IS BACKFILLED:
A. Fill the tank to the normal operating level.
B. Check for leaks in all water -tight seals.
C. Tum the blower ON and observe the operation of the airlift. A robust splash should be present.
D. Check for excessive back pressure: Seal all access covers, place hand about 8 inches [20 cm] from FAST® vent, if air flow is
felt then excessive back pressure exists and the system's vent must be upgraded.
E. Check for proper water level over the media. The normal water line should be —2" [5 cm] over the media.
F. Check for proper alarm function. Turn OFF the blower circuit breaker and wait for the alarm to sound. If the alarm does not
sound after 30 seconds, then review the electrical installation procedures.
G. Turn the blower back ON.
H. Backfill the excavation.
I. Lastly, record the FAST® unit's serial number in the Service Manual.
