Part II
Page 1 of 14
PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or"the Division"
Means the Division of Environmental Management, Department of Environment, Health and
Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33
USC 1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value)of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under"Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week(arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under"Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as
"Daily Maximum" under"Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The"daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration" for the discharge. It is
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through September, and October through December.

Part II
Page 3 of 14
7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow,
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of
discharge and combined proportional to the rate of flow measured at the time of
individual sample collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the
sampling point. Flow measurement between sample intervals shall be determined by
use of a flow recorder and totalizer, and the present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time
of greater than 24 hours. In such cases, effluent grab samples may be collected at time
intervals evenly spaced over the 24 hour period which are equal in number of hours to the
detention time of the system in number of days. However, in no case may the time interval
between effluent grab samples be greater than six (6) hours nor the number of samples less
than four(4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b. 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).

Part II
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next
day. However, for purposes of this permit, any consecutive 24-hour period that reasonably
represents the calendar day may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.

Part II
Page 8 of 14
2. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also
includes adequate laboratory controls and appropriate quality assurance procedures. This
provision requires the operation of back-up or auxiliary facilities or similar systems which are
installed by a permittee only when the operation is necessary to achieve compliance with the
conditions of the permit.
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or
operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to
the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to
be exceeded, but only if it also is for essential maintenance to assure efficient operation.
These bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal

Part II
Page 9 of 14
periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance;and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (I) of this section.
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
•
An upset constitutes an affirmative defense to an action brought for noncompliance with
such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1)An upset occurred and that the permittee can identify the cause(s) of the upset;
(2)The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this
permit.
(4) The pennittee complied with any remedial measures required under Part II, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset
has the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in
a manner such as to prevent any pollutant from such materials from entering waters of the State
or navigable waters of the United States. The permittee shall comply with all existing federal

Part II
Page 10 of 14
regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503,
any permit issued by the Permit Issuing Authority for the utilization/disposal of sludge may be
reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40
CFR Part 503. The permittee shall comply with applicable 40 CFR Part 503 Standards for the
Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the
regulation, even if the permit is not modified to incorporate the requirement. The permittee
shall notify the Permit Issuing Authority of any significant change in its sludge use or disposal
practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM
Regulation, Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability,
to prevent the discharge of untreated or inadequately treated wastes during electrical power
failures either by means of alternate power sources, standby generators or retention of
inadequately treated effluent.
SECTION D. MONITORING AND RECORDS
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the
volume and nature of the permitted discharge. Samples collected at a frequency less than daily
shall be taken on a day and time that is characteristic of the discharge over the entire period
which the sample represents. All samples shall be taken at the monitoring points specified in
this permit and, unless otherwise specified, before the effluent joins or is diluted by any other
wastestream, body of water, or substance. Monitoring points shall not be changed without
notification to and the approval of the Permit Issuing Authority.
2. Reporting
Monitoring results obtained during the previous month(s) shall be summarized for each month
and reported on a monthly Discharge Monitoring Report(DMR)Form (DEM No. MR 1, 1.1, 2,
3) or alternative forms approved by the Director, DEM, postmarked no later than the 30th day
following the completed reporting period.
The first DMR is due on the last day of the month following the issuance of the permit or in the

disposal, approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless
other test procedures have been specified in this permit.
To meet the intent of the monitoring required by this permit, all test procedures must produce
minimum detection and reporting levels that are below the permit discharge requirements and
all data generated must be reported down to the minimum detection or lower reporting level of
the procedure. If no approved methods are determined capable of achieving minimum
detection and reporting levels below permit discharge requirements, then the most sensitive
(method with the lowest possible detection and reporting level)approved method must be used.
5. Penalties for Tampering
The Clean Water Act provides that any person who falsifies, tampers with, or knowingly
renders inaccurate, any monitoring device or method required to be maintained under this
permit shall, upon conviction, be punished by a fine of not more than $10,000 per violation, or

Subject: Sand Filter Loading Rate
Authorization to Construct AC0084255
Juvenile Diagnostic Center WWTP
Gaston County
Dear Mr.Beasley:
After review of the permit and subject authorization to construct,I have several concerns:
•The existing permit allows a maximum discharge flow of 7,500 gpd. The existing treatment system
was estimated to be capable of treating 3,800 gpd during the initial permit issuance by the Mooresville
Regional Office. The wastewater treatment alternatives document supports a projected flow of 5,550
gpd. A letter should be submitted clearly stating what monthly average permitted flow is required for
this facility.
•Treatment capacity-The Division's current maximum hydraulic loading for an intermittent (single
pass) sand filter is 1.15 gpd/ft2. The currently proposed 600 ft2 sand filter exceeds this level at both
the projected and permitted flows. Revised plans should be submitted providing an adequately sized
sand filter,or justification should be provided to justify the proposed loading rate.
The wasteload allocation has been completed for relocation to Little Long Creek. A BOD5 limit of 30
mg/1 has been established at this discharge point. Upon receipt of the permitted flow verification, the
draft permit will go out for public notice. The authorization to construct request can be processed during
the public notice period if design revisions are received no more than 15 days beyond the public notice
date. If you have any questions, please contact me at 919-733-5083, ext. 541.

Gaston County, N. C.
Dear Mr. Nizich:
This is to reply to your letter of December 19, 1995, to Mr.
William Beasley, Gaston County Public Works Director, on the
above referenced project, concerning one item that needs
addressing.
Enclosed is a copy of a letter dated February 25, 1995, in which
we proposed and submitted plans to abandon the existing sand
filter and construct a new one and change the discharge point to
Little Long Creek. We have been trying since that date to obtain
the Permit to Construct. It was our understanding and from our
interpretation of the Permit Conditions (enclosed is a copy of
the SUPPLEMENT TO PERMIT COVER SHEET -Item 2 on this sheet) and
all through the Permit that the effluent should be piped to
Little Long Creek. Thus, it is a condition of the Permit that we
can discharge to the tributary to Little Long Creek OR to Little
Long Creek. Therefore, I do not agree with your statement that
the permit "only allows discharge to the unnamed tributary" .
Nobody from Mooresville or Raleigh has mentioned this before. It
is hoped that we are not at the same point we were a year ago and
it will take another year to resolve.
Please act on this matter just as soon as possible.
Thank you.

Waste Treatment Plant Improvements
Juvenile Detention Center
Dallas-Cherryville Highway
Gaston County, N. C.
Dear Sir or Madam:
Enclosed are three ( 3) copies each of the plans and
specifications on the above referenced project for your approval
and/or comments.
The proposed improvements as submitted are to update an existing
4,000 Gallon Septic Tank, a Dosing Tank with a 3" siphon and 700
gallons in capacity, and an existing 98' by 30' surface sand
filter. Structurally, the filter walls are falling in on the
sand filter and the sand filter has all kind of problems
(distribution piping on top, doubtful correct grade of sand,
filter effluent piping, etc. ) . Gaston County recently received
the above referenced draft permit. They cannot monitor the
existing filter in that we have not been able to find the pipe or
plant effluent discharge as of this date. In reviewing the
permit conditions, it is obvious that the effluent should be
piped to Little Long Creek which is what we are proposing to do
now. We are also proposing a new filter as shown on the plans
along with the proposed chlorination of the effluent to comply
with the Permit. It is proposed to construct the facilities
immediately so the system will operate satisfactorily and then
abandon the existing surface sand filter. This proposal is
submitted while we study a possible connection to the Town of
Dallas sewer system which is approximately 5,500 feet away by
gravity down Little Long Creek. Furthermore, this project
possibly could be tied into a Gaston County School sewer project
(Costner School) .

Dear Mr. Beasley:
The Division of Environmental Management, Permits and Engineering Unit,hereby acknowledges
receipt of your request for an Authorization to Construct wastewater treatment facilities in accordance
with NPDES Permit Number NC0084255. This application has been assigned the number shown
above. Please refer to the application number when making any inquiries about this application.
Preliminary review indicates that the following items must be addressed before final action is taken:
•Discharge Relocation-The submitted plans and specifications indicate that the discharge point is
being relocated to Little Long Creek. Since the existing permit currently only allows discharge to the •
unnamed tributary to this creek a permit modification is required. Discharge limits must first be
determined for this new location prior to approval of the Authorization to Construct.
Please be aware that the Division's regional office, copied below, must provide recommendations from
the Regional Supervisor prior to final action by the Division.
If you have any questions regarding this matter,please contact me at 919-733-5083,ext. 541.

INSTRUCTIONS TO BIDDERS
1. SCOPE OF PROJECT:
The scope of this project is the construction of a 30' long by
20' wide sewer surface sand filter; installing a 2,000 Gallon
Precast Septic Tank with no baffle walls at the incoming sewer
line; one 1,000 gallon precast septic tank with a distribution
box on top of it which gives access to a Sanuril tablet
chlorinator all to serve as a chlorine contact chamber;
approximately 169 feet of 8" PVC gravity sewer line;
approximately 342 feet of 8" Ductile Iron gravity sewer line; 3
manholes; approximately 100 feet of 6" PVC sewer line to connect
the existing facilities to the proposed new filter system; 0.6
acres of clearing, grubbing, and grassing; minor grading; other
miscellaneous piping; approximately 800 square yards of class 1
Rip-Rap 18" deep; and approximately 140 tons of # 78M washed
stone for pipe bed stabilization and dewatering under the gravity
sewer pipe and constructing a washed stone 10' wide access route
to Little Long Creek. The Contractor will build the above
facilities and have operational. He will then connect the
existing dosing tank to the new sand filter as shown on the
plans. He will then destroy and haul off-site the existing
concrete block comprising the existing sand filter, backfill, and
grade, fertilize and grass the area.
One Contractor (Contract A) will furnish and install the surface
sand filter and chlorinator, make the tie-ins from the existing
dosing tank to the new sand filter and tie-in to a pipe left
stubbed out by the second Contractor (Contract B) . Contract A
will do all work 5' upstream of Station 0+00 (Manhole # 1)
including the clearing and grubbing, grading and grassing within
50' of the sand filter as shown on the plans. Contract B will
install all outfall pipe from Manhole # 1 to Little Long Creek
including all clearing and grubbing, grassing and making a washed
stone 10' wide access walk to Little Long Creek.
No particular construction difficulties are expected except for
the swampy or high groundwater conditions along the outfall line
between Manholes 2 and Little Long Creek (approximately 340
feet) . This line will have to be installed with adequate
draining or pumping and installing stabilization and dewatering
stone.
Access to the project will be limited to the proposed permanent
and construction easements as shown on the Plans.
No soil borings or auguring for rock has been done on this
project. The project is unclassified excavation - i. e. , no
payments for rock encountered as set forth elsewhere in these
specifications. The Contractor is to make his own assumptions
about the locations or density of the rock in the area. He is
8 - 1

encouraged to make his own drilling or auguring. The extent of
utilities has been spotted as far as known. However, it is
incumbent upon the Contractor to properly locate the existing
utilities before setting final inverts or grades.
2. ESTIMATED QUANTITIES:

METHODS OF CONSTRUCTION
1. GENERAL:
Construction of this project shall be done in accordance with the
Engineers plans, these specifications, and as directed by the
Engineer. Should conditions be encountered in the work which are
not covered by these specifications or where it would not be
practical or feasible to proceed with the work in strict
accordance with the specifications or plans, then the contractor
shall notify the Engineer and await instructions from him before
proceeding with the work.
2. EXCAVATION - EARTH:
The contractor shall make in open cut, to the lines and grades as
shown on the plans, all excavation required for structures, pipe
lines, building connections to sewers, and appurtenances. The
contractor shall provide all sheathing and bracing, drainage,
pumping, backfilling, and other incidental work necessary to the
safe prosecution of the work. On all structures, the surplus
excavation not required for backfilling around the structures
shall be disposed of in a manner satisfactory to the Engineer.
The Contractor will be responsible for all construction stakeout
to agree with the plans.
3. TRENCHING AND TRIMMING:
The excavation between the sides of the trench must be of
sufficient width to permit the work to be done in the manner
specified. The bottom of all trenches shall have a clear width
of at least one foot wider than the external diameter of the
pipe. Whatever the nature of the ground will permit, the bottom
of the excavation shall have the shape and dimensions of the
outside of all pipes and structures; ample space shall be
provided in the trenches around the joints to enable the workers
to reach the pipe and properly make the joints. The pipe shall
be laid in a bed of washed stone with a minimum depth of 6" under
the pipe (see details on the detail sheet) and the washed stone
shall be poured around the pipe to the top of the pipe before
dirt is allowed as backfill.
4. SHORING:
Wherever necessary to prevent caving of the banks or injury to
workmen, pipe, work, or sludge drying bed, the contractor shall
at his own expense, brace and sheath the trenches or excavation
sufficiently to overcome the difficulties. If such sheathing and
bracing is left permanently in the trench or excavation by order
of the Engineer, it shall be cut off one foot below grade.
The Contractor shall comply with all aspects of the most recent
revisions of OSHA.
F - 1

5. CLEARING AND GRUBBING:
(A) Clearing - All trees, logs, brush, boulders, and other
objectionable material to the centerline of the telephone line
shall be removed and hauled off-site and properly disposed.
(B) Grubbing - All stumps and roots and other objectionable
matter shall be grubbed and removed off-site.
6. WATER IN TRENCHES:
Wherever groundwater is encountered, the contractor will be
required to install such equipment and carry on the construction
in such a manner as to provide the best possible laying
conditions. He shall remove all water which may be accumulated
or be found in the trenches or other excavations made under this
contract by pumping or bailing, and no pipe shall be laid until
such water has been removed from the trench. If groundwater is
encountered it will be required that at least 6" of washed stone
be placed in the trench to rid the trench of groundwater. The
contractor will not be permitted to drain water through the sewer
pipe. The ends of the pipe in the trench shall be kept closed
with a tight fitting plug to prevent washing of dirt or debris
into the sewer line. Water so removed from the trench must be
disposed of in such a manner as not to cause injury to public
health nor to public or private property, nor to the surface of
the street, nor cause any interference with the use of the
streets by the public.
7. BEDDING:
All sewer lines and manholes shall be installed on a minimum of
6" of fine washed stone for stabilization and firm bedding. The
exact nature of the material to be excavated is not known. It is
proposed to use the stone as a stabilization and de-watering
process. The proposed trench stabilization cross-section of the
pipe is shown on the Detail Sheet of the plans. The washed stone
shall be continued to the top of the pipe.
8. BACKFILLING:
For the depth of at least two feet over the top of the pipe, the
material used for backfilling trenches shall be clean earth, sand
or rock dust and washed stone under and around the pipe. The
space between the pipe and the bottom and sides of the trenches
shall be washed stone (#67 or equal) and packed full by hand and
thoroughly tamped with a light tamper, as fast as placed, up to
the level of the top of the pipe. The filling shall be carried
up evenly on both sides. The pipe shall then be covered
carefully to a depth of at least eighteen (18) inches above its
top, and at least one man engaged in tamping shall be provided.
The material shall be deposited carefully in the trench to avoid
injury to the sewer line. It shall be placed in layers that
shall not exceed six (6) inches in thickness (depending on what
F - 2

type of compaction techniques the Contractor is using) and each
layer shall be carefully and solidly tamped with appropriate
tools in such a manner as to avoid injury to or to disturb the
completed sewer. Compaction of at least 95% maximum density as
established by the Standard Proctor tests and in accordance with
the latest AASHO specifications for compaction. The contractor
will be required to furnish evidence of the percent compaction at
the contractors expense.
The foregoing applies in all cases where the sewer is laid under
or along the shoulders of streets and roadways, in sub-divided
sections, or in other places where compacting the trench
throughout its depth may be required; the remainder of the
trench, above an elevation of eighteen (18) inches higher than
the crown of the sewer, shall be backfilled with approved
material free from organic matter, no layer to be more than one
(1) foot thick and each layer to be thoroughly tamped with
rammers weighing not less than twenty (20) pounds, before another
layer is deposited. Surplus material shall be re-moved but the
contractor will be held responsible for replacing such material
where required due to subsequent settlement. Where the trench is
located in outlying districts, such as across farm lands, fields,
etc. , no tamping will be required above an elevation eighteen
(18) inches higher than the crown of the sewer.
No heavy rock shall be dropped into the trench until there is at
least three (3) feet of fill over the top of the sewer, and in
depositing rock in the trench, care must be taken that the rock
does not injure the structure. All spaces between pieces of rock
shall be filled with earth to insure there being no voids.
Where sheathing is drawn, all cavities remaining in or adjoining
the trench shall be solidly filled.
Backfilling within two (2) feet of manholes, catch basins, etc. ,
and other special structures shall be of selected material, free
from organic material and rock. It shall be uniformly deposited
on all sides and unless otherwise permitted, solidly tamped in
such a manner as to avoid injury to the structures or producing
unequal pressure on them. All backfilling compaction will be in
accordance with the above paragraphs.
9. ROCK:
All classifications are unclassified. The contractor will not
receive compensation for removing any rock. No soil borings have
been made on the project such that the extent of any rock is not
known. When rock excavation is necessary at the Contractor's
expense, the contractor shall excavate the same as near the neat
lines of the trench as practicable and he shall take all due
precautions in the pursuance of the work. He will be held
strictly responsible for all injury to life and the public and
private property. Rock excavation shall extend six (6) inches
below the invert of the pipe.
F - 3

10. EXISTING PIPES:
The contractor shall use every precaution to preserve intact all
existing pipes under the ground. Where one is damaged, he shall
repair or replace it immediately at his expense.
11. OBSTRUCTIONS TO TRAFFIC:
The excavated material shall be placed on one side of the trench
in such a manner as not to obstruct any drain or unnecessarily
obstruct any passageway. All street hydrants, water valve boxes,
fire alarm boxes, and letter boxes shall be kept accessible for
immediate use. At street crossings, the contractor must, when
necessary, provide a safe bridge with railings, to allow
pedestrians to cross the trench. The contractor shall provide,
without additional compensation, suitable temporary channels for
the water that may flow along or across the site of the work.
12. RATE OF PROGRESS:
Without permission from the Engineer, not more than 300 feet of
trench shall be opened in advance of the completed work in any
section, and in all cases, the work of excavation, pipe laying
and backfilling must move forward at approximately equal rates of
progress. Any exception to these requirements, over any
considerable length of time, must be with the consent of the
Engineer.
13. TESTS:
The contractor, on completion of the pipe laying, shall
thoroughly clean by flushing and test all lines and manholes to
the satisfaction of the Engineer. The contractor shall furnish
the necessary equipment required by the Engineer for the purpose
of the tests. Any or all of the following tests may be made on
sewer after completion at the option of the Engineer:
a. When looking from one manhole to another toward a light, the
opening shall show circular.
b. Sewer shall be flushed and the appearance and velocity of the
water noted.
14. INFILTRATION LIMITS:
The allowable limit of ground water infiltration for the entire
system of new sewers of any one trunk, interceptor or outfall
sewer, including connecting laterals and house connections made
under this contract shall not exceed the following limits of
infiltration rates for full acceptance:
10 gallons per inch of diameter of the sewer per mile of
sewer in 24 hours.
F - 4

Measurement of the infiltration shall be made direct at the point
where the main enters the outfall line. This measurement shall
be made before sewage flows are allowed in the sewers. Under dry
soil conditions, the manhole shall be partially filled and the
volume of water in the manhole during the period of the test.
Other methods of testing may be required if there is an
accountable infiltration source.
Tests for both infiltration and exfiltration for all lines will
be required. The contractor will be required to use Air Testing
for the exfiltration tests. The test shall be as set forth in
ANSI-ASTM C 828-78 or other widely used, acceptable to the
contractors expense and shall be done in the presence of the
Engineer prior to acceptance by the Owner.
All infiltration tests shall be made by the contractor in the
presence of the Engineer. All expense of the above tests shall
be borne by the contractor and be included in the unit prices bid
per foot of sewer under each respective size and depth of cut of
sewer.
15. PIPE LAYING:
The contractor shall install the sewer lines or structures as
shown on the plans and as explained in the Specifications
(Contract A will be for the Sand Filter and Chlorinator and
Contract B will be for the outfall portion of the project) . The
material uses, the trenching and backfilling shall conform to the
requirements of the above items.
In laying pipe, each piece shall be set exactly to grade.
Great care must be taken to leave no projecting strings of gasket
on the inside of the sewer, and to make all joints as nearly
watertight as possible.
16. PAYMENT:
Payment will be made at the price bid for sewers per linear foot
or at the lump sum prices of the two contracts as indicated on
the proposal and shall include all materials, excavating,
backfilling, clearing and grubbing, laying, labor, shoring,
testing, and equipment necessary to complete the work for each
contract, ready for use.
17. SEEDING ALONG PROJECT RIGHT-OF-WAY:
All disturbed areas in the project will be seeded in the
following manner:
Seedbed Preparation - Areas to be brought to proper grade.
Limestone shall be applied and worked into the soil. Soil shall
be scarified to a depth of 5 inches except for cut slopes steeper
than 2:1. On cut slopes steeper than 2:1, surfaces shall be
F - 5

•
scarified, grooved, trenched, punctured, or otherwise loosened to
form pockets, ridges or trenches in which seeding materials can
lodge. After scarifying, surface should be disc harrowed to
smooth up area. Seed and fertilizer should then be applied and
covered with drag harrow and gone over with cultipaker.
After seeding is completed, the area is to be cleared of rocks
and roots and then mulched with straw or other approved material.
When using straw, it is to be covered with a sufficient amount of
asphalt to hold it in place.
1. Apply agricultural lime at the rate of 2 tons/acre.
2. Apply 10-10-10 commercial fertilizer at the rate of
900 lbs./acre.
3. Seed in accordance with the following schedule and
application rates:
DATE TYPE PLANTING RATE
Aug. 15 - Nov. 1 Tall Fescue 300 lbs./ac.
* Nov. 1 - Mar. 1 Tall Fescue & 300 lbs./ac.
Abruzzi Rye 25 lbs./ac.
Mar. 1 - Apr. 15 Tall Fescue 300 lbs./ac.
Apr. 15 - Jul. 30 Hulled Common
Bermudagrass 30 lbs./ac.
Jul. 15 - Aug. 15 Tall Fescue & 300 lbs./ac.
Browntop Millet 35 lbs./ac.
OR Sorghum Sudan
Hybrids 30 lbs./ac.
4. Mulch with straw applied at the rate of 2 tons/acre.
* Heavily mulched during January - March period.
On cut and fill slopes steeper than 2"1 and 1/2 lb. Sericca
Lespedza per 100 sq. yds. . On fill slopes, add 1/2 lb. Grain Rye
per 100 sq. yds. .
If seeding is done between May 1 and September 1, add 1/2 lb.
Sudan Grass for protection of Fescue. Rye Grain on fill slopes
can be omitted during this period.
The amount of straw will vary from 80 lbs. to 120 lbs. per 100
sq. yds. . The actual amount is determined by visual inspection
so as to allow some sunlight to penetrate and air to circulate,
but also partially shade the ground and reduce erosion and
conserve moisture.
No seeding will be allowed to stand more than 24 hours without
being mulched.
No seeding shall be done when soil is too wet to work.
The Engineer and the Gaston County officials will make the
decision as to final acceptance of all right-of-way work.

Evaluation of Wastewater Treatment Alternatives
Juvenile Diagnostic Center Wastewater Treatment Facility
Gastonia, North Carolina
Introduction
Gaston County operates the Juvenile Diagnostic Center surface sand filtration
wastewater treatment system on the grounds of Camp Sertoma located in Dallas,
North Carolina. A site location map is presented as Figure 1. The existing
system has a design capacity of approximately 5,000 gallons per day and serves
four County owned facilities. The existing system discharges to Little Long
Creek under National Pollutant Discharge Elimination System (NPDES) Permit
No. NC0084255.
Gaston County wishes to upgrade the existing system and replace the outfall to
Little Long Creek to accommodate the effluent monitoring requirements of the
NPDES permit. North Carolina Department of Environment, Health and Natural
Resources (DEHNR) regulations require an evaluation of wastewater disposal
alternatives be conducted for surface water discharges prior to granting
authorization to construct.
In accordance with DEHNR guidance documents, the following non-discharge
alternatives were evaluated:
1. Connection to a sewerage system
2. Subsurface disposal
3. Spray irrigation
This report discusses the evaluation of these non-discharge alternatives and
provides an economic comparison between the feasible non-discharge alternatives
and the proposed system upgrade.
. —Current and Proposed Wastewater Treatment Systems
The existing wastewater surface sand filtration treatment system consists of a
1,000-gallon septic tank and a 4,000-gallon septic tank in series, a 700-gallon
dosing tank, a 97.6-foot by 30-foot surface sand filter, and an eight-inch
terracotta pipe outfall to Little Long Creek.
The current system serves Gaston Skills, Gaston County Comprehensive Day
Center, Gaston County Juvenile Diagnostic Center and Camp Sertoma. The
Gaston Skills facility, including staff members, serves approximately 120 people,
Resolve Environmental Services, P.A. 1 Gaston County Public Works Department
December 12, 1995 Gastonia, North Carolina

Gaston County Comprehensive Day Center approximately 60 people, the Juvenile
Diagnostic Center approximately 32 people and Camp Sertoma approximately 30.
Camp Sertoma operates during the summer months, while the other facilities
served by the treatment system operate year round. These facilities currently
serve approximately 250 people during full operation and generate approximately
5,000 gallons per day of domestic wastewater. The County desires to expand the
diagnostic center by an additional 15 beds. Based upon current and projected
occupancy rates, the County anticipates a wastewater flow of approximately 5,600
gallons per day for the proposed system. Flow projections based on criteria set
forth in 15A NCAC 2H.0200 are presented in Table 1.
The proposed system is to include two 1,000-gallon septic tanks and one 4,000-
gallon septic tank in series, a 700-gallon dosing tank, a three-foot by three-foot
distribution box, a 30-foot by 20-foot high-rate sand filter, a 1,000-gallon chlorine
contact chamber, and an eight-inch PVC outfall to Little Long Creek. Gaston
County anticipates constructing the new distribution box, sand filter, and chlorine
contact chamber adjacent to the effluent end of the existing sand filter. The
existing sand filter is proposed to be abandoned in-place upon initiation of
operation of the new treatment units. Plans and specifications for the system
upgrade, prepared by Fox Engineering, were initially submitted to DEHNR on
February 25, 1995.
Wastewater Alternatives
As mentioned above, three non-discharge disposal alternatives were evaluated for
the Juvenile Diagnostic Center system, including connection to a neighboring
collection and disposal system, subsurface disposal and spray irrigation systems.
Connection to Sewerage System
The City of Gastonia and the Town of Dallas operate wastewater collection
systems within a one-mile radius of the Juvenile Diagnostic Center system (Figure
2). The nearest tie-in point, to the Town of Dallas system, is approximately
4,800 feet directly east of the facility.
Wastewater from the Gaston County facilities to the Town of Dallas collection
system can be conveyed by gravity flow via a collection system extension
paralleling Little Long Creek. Connection to the Town of Dallas system can be
made south of the College Park subdivision near Highway 321. A 12-inch
sanitary sewer serves the Town of Dallas system in this area.
Resolve Environmental Services, P.A. 2 Gaston County Public Works Department
December 12, 1995 Gastonia, North Carolina

Sewer facilities required to direct flow from the Juvenile Diagnostic Center
collection system to the Town of Dallas collection system include approximately
4,800 linear feet of eight-inch PVC sanitary sewer, eighteen sanitary precast
manholes, and appurtenances.
Flow into the Town of Dallas system would be directed to the Town of Dallas
Wastewater Treatment Facility (NPDES Permit No. NC0068888). The Town of
Dallas plant has a design capacity of 0.6 MGD and is currently treating an
average daily flow of approximately 0.03 MGD. Capacity exists at the Town of
Dallas plant for flow from the County facilities.
The City of Gastonia sanitary sewage collection system extends as far north as the
Agricultural Building on Highway 275. Connection to the City of Gastonia
system would require the installation of a sewage pumping station to convey flow
up to Highway 275, approximately 1,500 linear feet of force main, approximately
3,700 feet of eight inch PVC sanitary sewer, 14 precast sanitary manholes, and
appurtenances.
Flow into the City of Gastonia system would be directed to the Long Creek
Wastewater Treatment Facility (NPDES Permit No. NC0020184). The Long
Creek plant has a design capacity of 8 MGD and is currently treating an average
daily flow of approximately 6 MGD. Capacity exists at the Long Creek Plant for
flow from the County facilities.
Subsurface Disposal and Spray Irrigation Systems
Both subsurface disposal and spray irrigation systems are land based disposal
alternatives. Land requirements for effective treatment depend largely on the
selected system and soil type(s) present at the disposal area.
Subsurface disposal and spray irrigation systems require land for active treatment,
reserve areas and buffer zones. Additionally, spray irrigation systems require
storage. Locally available information such as Soil Conservation Service (SCS)
maps and soil descriptions, site topographic maps, geologic maps, and wastewater
data was used to determine the general acceptability of the proposed and existing
site for wastewater disposal. The proposed land treatment site is located west of
Dallas, and south of the Little Long Creek (Figure 3).
Site and Soil Description
County-owned property comprising the site, including area occupied by
structures, encompasses approximately 19 acres of land. Approximately 0.5 acres
Resolve Environmental Services, P.A. 3 Gaston County Public Works Department
December 12, 1995 Gastonia, North Carolina

are occupied by the existing treatment system. The property is bounded to the
north and east by residential and agricultural acreage, to the west by commercial
and residential property, and to the south across Highway 275 by residential
property. Slopes range from 8% to 20% and are predominantly north facing.
Drainage from the site ultimately discharges to Little Long Creek. It is expected
that land treatment hydraulic inputs would contribute primarily to shallow
groundwater and surface water in the area.
The Gaston County Soil Survey was found to be applicable for purposes of a
general discussion of land treatment following a cursory investigation of the
existing and surrounding sites. Based on soil series maps and communications
with SCS personnel who have mapped the area, there appears to be one soil map
unit present on the site (Figure 4).
The soil and existing facilities were examined during a site visit on May 9, 1995.
The site is located on a relatively flat upland area behind Camp Sertoma. Slopes
do not exceed 20% in the area. Soil samples were selected from a ten-foot long
by four-foot deep trench dug by a backhoe.
The soil on the site had a sandy clay loam surface layer approximately eight-
inches thick. The subsoil extends to a depth of about 34 inches. The subsoil is
yellowish brown clay loam in the BA horizon, yellowish orange clay in the Bt
horizon, and yellowish brown clay loam in the BC horizon. Low chroma
drainage mottles were observed in the Bt horizon. Structure was granular to
subangular blocky; the soil was slightly plastic and sticky in the Bt horizon (Table
2).
Permeability and hydraulic conductivity is moderate, and shrink-swell potential
is low. The water table is not within a depth of five feet. Depth to bedrock is
greater than five feet. This soil is strongly acid to very strongly acid. Hazard
of erosion is none to slight. This soil appears to map as a Pacolet at less than
15% slope (Figure 2). Steepness of slope and moderate permeability are the main
limitations for wastewater application at the Camp Sertoma site.
Low-Pressure Pipe System
To determine the land requirement for a low-pressure pipe system, soil
permeability was evaluated to determine a maximum loading rate. From Table
2, the soil profiles in the BA and Bt horizons show distinct textures. The BA
horizon is described as a clay loam whereas the Bt horizon is described as a clay.
These two textures are markedly different in term of permeability; therefore for
the purposes of determining a maximum loading rate, the soil is assumed to be
Resolve Environmental Services, P.A. 4 Gaston County Public Works Department
December 12, 1995 Gastonia, North Carolina

a clay, with a permeability of 90-120 min/in. In contrast, a clay loam typically
has a permeability of 40-60 min/in.
The maximum loading rate for a low-pressure pipe system in a clay soil is 0.10
gallons per day per square foot.' For a design flow of 5,600 gallons per day, the
land requirement for the low-pressure pipe distribution system is 56,000 ft2 or
approximately 1.3 acres. Accounting for a one hundred percent reserve area, the
land required for wastewater distribution is approximately 2.6 acres. This
estimation does not include buffer requirements.
Spray Irrigation System
The land requirement for a spray irrigation system based on a 5,600 gallons per
day design flow is calculated directly from a water balance as 1.35 acres (Table
3). This assumes operation of 360 days per year. Based on this criteria, and an
assumed 100% reserve area, it is estimated that approximately 2.70 acres land is
required for spray irrigation wastewater disposal use. The land requirement
projection is exclusive of storage and buffer requirements.
Spray irrigation systems are required under DEHNR regulations to include a
minimum of 45 days storage capacity. Calculation of required storage based
upon waste load conditions at the site indicates that a minimum of 50 days of
cumulative storage is required (Table 4). At a design flow of 5,600 gallons per
day, approximately 280,000 gallons of storage will be required for the County
facilities.
Approximately 4.0 acres of land are available for wastewater treatment at the
County facilities, excluding area currently occupied by the existing wastewater
treatment units. Of the available land, approximately 1.5 acres are excluded by
required set backs. Approximately 0.75 acres of the remaining 2.5 acres are
excluded because they are located in the flood plain of Little Long Creek (Figure
5). The remaining portion of County owned land is of insufficient size to serve
either low-pressure pipe or spray irrigation treatment facilities.
Land adjacent to the County owned facilities to the north and east is currently
undeveloped and is owned by a single individual. The property is zoned for
residential or agricultural use and is currently classified as farm land. Land
value, according to county tax assessment records is approximately $550.00 per
acre. The current property owner, however, is reluctant to sell the property for
wastewater treatment use. Undeveloped land to the west of the facility is

SG-82-03. May 1982
Resolve Environmental Services, P.A. 5 Gaston County Public Works Department
December 12, 1995 Gastonia, North Carolina

similarly privately owned and current owners are not interested in selling the
property for wastewater treatment use.
While environmental conditions indicate feasibility of low-pressure pipe or spray
irrigation systems, the lack of sufficient county-owned land and the reluctance of
the adjacent property owners to sell preclude these alternatives from further
evaluation.
Cost Comparison
Cost estimates were prepared for the following alternatives based on
environmental feasibility:
A. Connection to the Town of Dallas sewage collection and treatment
system (Town of Dallas).
B. Connection to the City of Gastonia sewage collection and treatment
system (City of Gastonia).
C. Upgrade and expansion of the existing Juvenile Diagnostic Center
treatment facility, including replacement of the outfall to Little
Long Creek (System Upgrade).
Wastewater alternatives and construction costs were evaluated relative to the
following areas:
1. Equipment and installation costs.
2. Engineering costs.
3. Costs of rights-of-way.
4. Operation and maintenance costs, including monitoring.
Individual cost estimates for the alternatives evaluated are presented in Table 5.
Present worth costs, including construction and operation and maintenance costs,
for the three alternatives are: Town of Dallas ($544,400.00), City of Gastonia
($654,664.00), and System Upgrade ($414,404.00).
Conclusions
From the environmental feasibility studies and cost comparisons discussed above,
the most cost effective wastewater treatment solution is to upgrade the existing
facilities and continue the 5,600-gallon per day discharge into Little Long Creek.
While discharges to the Town of Dallas and City of Gastonia collection systems
are environmentally feasible,both alternatives are cost prohibitive when compared
to an appropriate upgrade of the existing treatment system. •

NPDES Authorization to Construct

Juvenile Detention Center
Gaston County
Dear Mr.Beasley:
The Division of Environmental Management has received your request dated
February 25, 1995 for an Authorization to Construct to update and repair an existing
wastewater treatment system. However, before we can review a request for an
Authorization to Construct, a$150.00 fee and an alternatives analysis must be submitted.
This analysis should include a review of alternatives to a surface water discharge, including
connection to the City of Gastonia sewer system. Relocation to a positive-flow stream
must also be considered, as should drip irrigation and construction of a conventional "non-
discharging" septic tank/sand filter system. Therefore, we are returning your application
materials. Enclosed please find the application materials submitted.
As stated above, you must submit a$150.00 fee and an alternatives analysis along
with the request for an Authorization to Construct. If you have questions regarding this
matter, please contact Susan Robson at(919) 733-5083, ext. 551.
Sincerely, •

Subject: NPDES Permit No. NC0084255
Juvenile Diagnostic Center WWTP
Gaston County, NC
Dear Mr. Wilkins:
Our records indicate that NPDES Permit No. NC0084255 was
issued on February 6, 1995 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 is Page 4 .
Page 4 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
reporting 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 forms, 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, and the
original and one copy be submitted as required.

Page Two
The remaining Parts of the Permit 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

Part II
Page 1of14
PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Environment, Health and
Natural Resources.
3. EC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33
USC 1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight)of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit. •
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured,divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria,is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week(arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value)of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under"Other Limits" in
Part I of the permit.
.c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as
"Daily Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen)is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration" for the discharge. It is
identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through September, and October through December.

• Part II
Page 3 of 14
7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow,
averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded
during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling,
when both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which
occurs continually without interruption throughout the operating hours of the facility. Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of
discharge and combined proportional to the rate of flow measured at the time of
individual sample collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the
sampling point. Flow measurement between sample intervals shall be determined by
use of a flow recorder and totalizer, and the present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time
of greater than 24 hours. In such cases, effluent grab samples may be collected at time
intervals evenly spaced over the 24 hour period which are equal in number of hours to the
detention time of the system in number of days. However,in no case may the time interval
between effluent grab samples be greater than six (6) hours nor the number of samples less
than four(4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be
representative of the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b. 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).

Part II
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight of the next
day. However, for purposes of this permit, any consecutive 24-hour period that reasonably
represents the calendar day may be used for sampling.
11.Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1)of the Clean Water Act.

3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this permit.
4. Bypassing of Treatment Facilities
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or
operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to
the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to
be exceeded, but only if it also is for essential maintenance to assure efficient operation.
These bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a pennittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal

periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
(C)The permittee submitted notices as required under Paragraph c. of this section.
(2)The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with
• such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs,or other relevant evidence that:
(1)An upset occurred and that the permittee can identify the cause(s)of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this
permit.
(4) The permittee complied with any remedial measures required under Part II,B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset
has the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in
a manner such as to prevent any pollutant from such materials from entering waters of the State
or navigable waters of the United States. The permittee Mall comply with all existing federal

PART IV - EVALUATION AND RECOMMENDATIONS
The County of Gaston requests that a new NPDES Discharge
Permit be issued to the County for the operation of and discharge
from an existing septic tank/surface sandfilter system located at
the County's Juvenile Diagnostic Center. According to Mr. Steve
Wilkins , Gaston County Facilities Management , this facility was
approved by the State years ago. However, the Mooresville Regional
Office has no records indicating that a permit was issued for this
facility. The facility serves a summer camp with 75 persons (staff
and students) .
An on-site inspection performed by staff of this Office
NPDES Permit Staff Report
Version 10/92
Page 4

revealed that the existing facility consists of a septic tank with
dosing siphon and a surface sandfilter with five (5) PVC
distribution lines in a fenced area. No disinfection unit is
installed at the facility. In addition, no discharge pipe was
observed. It should be pointed out that this facility was a
subsurface sandfilter system which was converted to a surface
system by Mervin Ratchford Septic Service approximately two to
three years ago. During the facility conversion, Mr. Racthford was
not able to locate the discharge pipe. The inspection also
revealed a segment of wall on the east side of the sandfilter had
collapsed due to recent storm events . It is likely that similar
incidents would occur in the future if the wall is not properly
reinforced.
The County needs to locate the discharge pipe, repair the
collapsed wall , and install a disinfection unit . It appears that
the current treatment capacity of the facility could not
accommodate the projected wasteflow, therefore, expanded treatment
facilities may be necessary. The existing facility may not be able
to meet the final limits (to be promulgated) , therefore, a time
schedule for meeting such limits may need to be included in the
Permit . Pending final review by the SERG, it is recommended that
a Permit be issued in consideration of the above.

Facility is requesting the issuance of an NPDES permit for this existing, unpermitted septic
tank- surface sand filter system. Gaston County wants to convert this 7,500 GPD plant to a
discharge system. A flow analysis indicates that both 7Q10 and 30Q2 flows are zero at this
discharge point. ( See Attached). Per Division procedure and NCAC regulations, new
facilities will not be allowed to discharge to zero flow streams. The County may have to
exercise the option recommended in the MRO staff report to have a ground absorption
system. The facility could also consider extention of the outfall pipe,directly to Little Long
Creek where the streamflow would be higher.
