the number of individual values.
h. Geometric Mean: The geometric mean of any set of values
is the Nth root of the product of the individual values
where N is equal to the number of individual values. The
geometric mean is equivalent to the antilog of the
arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of
zero (0) shall be considered to be one (1).
Composite Sample: These samples consist of grab samples
collected at equal intervals and combined proportional to
flow, a sample continuously collected proportionally to
flow, or equal volumes taken at varying time intervals. If a
composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent
grab samples shall be no greater than hourly. Intervals
between effluent grab samples shall be no greater than
hourly except where the detention time of the wastewater in

Subject: NPDES Permit No. NC 0070041
Metromont Industrial Park
Mecklenburg County, NC
Dear Mr. Cook:
Our records indicate that NPDES Permit No. NC 0070041 was
issued on December 10, 1987 for the discharge of wastewater to
the surface waters of the State from your facility. The purpose
of this letter is to advise you of the importance of the Permit
and the liabilities in the event of failure to comply with the
terms and conditions of the Permit. If you have not already done
so, it is suggested that you thoroughly read the Permit. Of
particular importance Page M3.
Page M3 sets forth the effluent limitations and monitoring
requirements for your discharge(s). Your discharge(s) must not
exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies,
sample types and sampling locations. Upon commencement of your
discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on the DMR
forms furnished to you by this Agency. If you have not received
these forms, they should be arriving shortly. If you fail to
receive the form, please contact this Office as quickly as
possible. I have enclosed a sample of the "Effluent" reporting
form (DEM Form MR-1), plus instructions for completing the form.
It is imperative that all applicable parts be completed,
otherwise the forms may be returned to you as incomplete.
Failure to properly complete the forms may also result in an
automatic $300.00 fine.
The remaining Parts of the Permit (Parts II and III) set
forth definitions, general conditions and special conditions
applicable to the operation of wastewater treatment facilities

and/or discharge(s). The conditions include special reporting
requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for
a certified wastewater treatment plant operator if you are
operating wastewater treatment facilities. Any changes in
operation of wastewater treatment facilities, quantity and type
of wastewater being treated or discharged, expansions and/or
upgrading of wastewater treatment facilities must be permitted or
approved by this Agency.
Failure to comply with the terms and conditions of an NPDES
Permit subjects the Permittee to enforcement action pursuant to
Section 143-215.6 of the North Carolina General Statutes. A
civil penalty of up to $10,000 per day per violation plus
criminal penalties may be assessed for such violations.
As a final note, an NPDES Permit is normally issued for a
five-year period. Permits are not automatically renewed.
Renewal requests must be submitted to this Agency no later than
180 days prior to expiration. Please make note of the expiration
date of your Permit. This date is set forth on Page M-1 or I-1
of the Permit. Also note that NPDES Permits are not
transferable. If you, as the Permittee, cease to need this
Permit, through cessation of the discharge, then you should
request that the Permit be rescinded.
As mentioned previously, the purpose of this letter is to
advise you of the importance of your NPDES Permit. Please read
the Permit and contact this Office at 704/663-1699 in Mooresville
if you have any questions or need clarification. We look forward
to providing any assistance.

PART IV - EVALUATION AND RECO MENDATIoNS
Due to the fact that the site investigation was conducted
immediately after a heavy rainfall in that region, the
stream -flow observed in the selected segment of an unnamed
tributary to Dixon Branch perhaps should not be adjudged as an
average flow under normal weather conditions. Therefore, a flow
analysis of the unnamed tributary should be performed prior to
the determination of issuing an NPDES discharge Permit for the
proposed facility.
The issuance of an NPDES discharge Permit for the subject
proposal is recommended, provided that the outcome of the flow
analysis indicates that the unnamed tributary meets the flow
criteria established by the Division of Environmental Management.

A. DESCRIPTION OF PROPOSED PROJECT
This project will consist of providing waste, water treatment for
the Metromont Industrial Park, located on U.S. Hwy. 21 North in Meck-
lenburg County, North Carolina. The treatment plant site will be con-
structed on land presently owned by Metromont Development Company. The
Owner's address is:
Metromont Development Company
P.O. Box 1292
Spartanburg, S.C. 29304.
The Owner will construct the plant and the service lines to the
Park in accordance with the requirements of the proper State and local
authorities rules and regulations.
The plant will have a nominal capacity of 30,000 gals. per day and
shall be designed to provide sewer service for 22 commercial business
connections as projected at this time.
The Owner will construct the full plant (30,000 gal. capacity) and
collection line service to the Park during this development. The plant
and collection lines are shown on the map included in this report.
The plant site is located near the low elevation point within the
Park. The plant site area is sufficiently large enough to, permit future
additions to the, plant of up to at least twice the capacity within its
boundaries.
The plant and all. appurtenances shall be new equipment of the pre-
engineered type furnished and installed under the direction of the manu-
facturer. The plant shall utilize the extended aeration process of waste
water treatment. This process and the proposed plant operation may be
briefly describe in general as follows:
"The objective of the waste water treatment plant is a high
degree of removal of polluting material from the waste water as it
passes through the plant. This is accomplished by observing a
planned operational and servicing program. The theoretical deten-
tion time for influent to remain in the plant shall be 24 hours.
The raw sewage enters the primary aeration tank through a
trash intercepting device. The trash intercepting device shall
include trash and grit chamber and a comminutor or may include
only a trash and grit chamber as preferred by the Sewer Authority.

The. sewage is thoroughly agitated bTdiffased air bubbling up
through the liquid causing the sewage to mix well and become
air entrained. The aerated sewage. flows from the aeration tanks
to the settling tank- Suspended solids in the form of sludge
separate from the liquids. behind a baffle and the stabilized
sludge settlesto the bottom to be returned through air pumps
to the inlet to the plant for recirculation. This sludge is
mixed with the raw sewage entering the plant and immediately
begins attacking. it. The sludge lines operate continuously. In
order to minimize excess sludge buildup in the settling tank, a
portion of the sludge is routed through aerobic sludge digester
compartments and only clear supernatant returns to the aeration
tanks. A portion of the aerated sewage in. the settling tank
rises behind the baffle and must be hosed. and agitated to cause
it to settle. This material is partially treated, air filled
and greasy, and requires skimming. The clear liquid from the
settling tank then flows over a. weir into the chlorine contact
department for biological disinfectant purposes and thence to
an outfall point as treated sewage effluent.
Plant tests will show when or if therehas been an excessive
sludge build-up. If excessive sludge build-up occurs, sludge
shall be. removed from the plant and either hauled awayby truck
to a designated disposal site or disposed. of by a method approved.
Air service to the aeration tanks is provided by two blowers
each equipped with an inlet filter and a sound. reducing muffler."
The plant will be designed to operate. at. less than full capacity
through the installment of additional valves and returns topermit the
operator to regulate the plant in accordancewith the. quality of in-
fluent.
In order to provide for surge discharges, theplant shall contain
a surge tank(s) appropriately sized as recommended by the plant manu-
facturer and based on the maximum flow as given in this report.
A flow diagram of the proposed facility is included in this report.
The treated effluent will be discharged into the waters of Long
Creek. The creek. is located at the western extremity of the plant and
has been judged tohave sufficient dry weather flow to receive the
quantity of discharge fromthe plant.

It is reasonable to assume that based on the, above treatment pro-
cess the BOD removal. shall be approximately 90 to 95 percent effective.
As of the date of the writing of this report no discharge permits
have been granted. for this facility nor have any legal requirements
been made applicable to the quality of the proposed discharge.
B. DESCRIPTION OF WASTE
The influent will consist entirely of domestic waste from the
businesses in the Park.
C THE SIZING OF THE PLANT AND CHARACTERISTICS ©F WASTE
The raw waste is calculated to be discharged. to the plant as
follows:
1. Calculations for Treatment Plant Size using 5,000 ga,l, Module
Plant.
Given: - 22 service connections (minimum).
- All waste domestic. type.
8 to 10 hour operation time for businesses. (5 day
week.
- All businesses to be co 'al with no special or
hazardous waste.
- No kitchens or food preparation activities.
- Minimum number of toilet and shower facilities.
No wash racks or waste process water.
Assume:- 25 gal per day per person waste.
Assume:- Three phase operation level. as follows:
Phase I 10,000 GPD Cap.
Phase II : 20,000 GPD Cap.
Phase III : 30,000 GPD Cap.
Therefore: 10,000 :'25 = 400 persons
20,000 ±25 = 800 persons
30,000 25 = 1,200 persons
Note: The above limits based on population served wi1.1 deter-
mine operating capacity level. of sewage treatment plant.

E. LOCATION OF SUBJECT AREA AND POINT OF DISCHARGE
1. See attached map.
F. GENERAL LAYOUT OF AREA TO BE SERVED
Enclosed in. this report is a map showing the location for the
Metromont 'Industrial Park. Information on the map includes the build-
ing sites, roads, topography, and the treatment plant site.
G. RECEIVING WATERS
1. The plant effluent will be discharged into Long Creek. The creek
flows into Dixon Branch, This stream is located on the location map
included in this report.
2. The chemical and biological characteristic s of the receiving waters
on the branch are mostly those of the natural drainage from the
watershed.
11. IMPACT ODISC 11a RGE ON RECEIVING STREAM
The creek is a natural., stream having a well defined channel. The
land above the creek and along the route of the stream is rolling and
sloping.
The bottom land on each side of the branch is relatively dry and
drains well. Most of the side drainage enters the branch from natural
drainage configurations. Although the banks of the branch are earth
they are relatively stable. Some sand bars or silt deposits are evi-
dent along the channel. The banks are approximately 1 to 1 slopes and
the bottom of the branch contains very little exposed bed rock.
Generally, the water in the branch remains rather clear. Little or
no cloudiness or coloration is evident. in the water. The overfalls along,
the branch do not exhibit any foaming action. The vegetation along the
branch is normal and shows good growth.
The branch flows in a westerly direction and has an average gra-
dient of approximately 0.5% between the plant site and U.S. Hwy. 21.
Since all sewage to the plant will be domestic waste water no heavy
concentrations of phenols, heavy metals, herbicides, etc., will be pre-

sent. Fecal coliform levels should be reduced to considerably less.
in the plant effluent than in. the receiving stream due to. the use of
chlorination. BOD removal will be specified to be at least 907 in
the plant effluent hence the nutrient levels of the receiving water
will not be adversely affected.
In conclusion, the plant operation and discharge quantities should
at least enhance the quality and increase the flow in the Creek.
I. EQUIPMENT AND SERVICE FAILURE OR SHUTDOWN
All mechanically operated component. parts of the sewer system will
be located in the plant area. Power sources are electrical as furnished
by the. Duke Power Company. There are. no lift stations or force mains re-
quired for the collection system.
When the. plant has. been constructed and accepted for operation, the
proper authorities, will assume ownership and operation of the plant and
collection lines. The Operator will maintain a staff of trained per-
sonnel and will provide for replacement parts for the system. Operation
of the plant will be closely supervised. In the event of plant operation
failure, the Operator will initiate immediate emergency actions to correct
the. malfunction in accordance with their plan. of operation for such an
occurrence.
J. CONSOLIDATION OF FACILITIES
As far as is known, there are no planned new construction of sewage
treatment facilities in the vicinityof the project or existing facil-
ities that might be consolidated with this project.
WASTEWATER COLLECTIONAND. TRANSMISSIONS:FACILITIES
1. Metromont Industrial Park is shown on the map included in this re-
port. All sanitary sewer lines shall be 8" diameter pipe with "0"
ringslip on rubber gaskets. All piping and. manholes shall be in
accordance with the. requirements of the. appropriate authorities.
All pipe runs between manholes shall be straight in alignment
and grade. No lift stations or force mains are required for the
system since all flow is gravity flow.
