RE: NCG510463 - Roscoe's Grocery / OAH case
Charles,
i We did not go to court, and Ms. Cain is now continuing with work at the site. She is being somewhat compliant.
So far, we. have only gotten one monitoring report from the site, and I am expecting another one soon. Her consultant
(information below) did submit a task authorization pre -approval for $100 to obtain the necessary NPDES permit (if they
turn the system back on).
The Task Authorization was approved by Raleigh, and I sent him back the signed authorization. You may not be familiar
with the UST Trust Fund, but at this time all work at Roscoe's Grocery is Trust Fund reimbursable, including necessary
permits.
When the consultant submitted the task authorization I did explain to him that the permit had lapsed and that he should
contact the DWQ about any other fees that may be associated with the lapsed permit.
Hope this helps, and please let me know if you receive their paperwork.

Charles,
I have been responding with our attorney on this site. Currently we do not have a date set for a hearing, but I expect it
to be in the next two -three months.
We have given the judge several dates in April and May that would work for us, but it is my understanding that Ms. Cain
has tried to push the date far into the future due.
She was assessed penalties in November 2009.
I will let you know if we come to a resolution.

BPA No. 0214.002
Dear Mr. Weaver:
2641-G Randleman Road
Greensboro, NC 27406-5159
[phone]
January 29, 1999
On December 21, 1998, your office informed Mrs. Anne Cain that the subject permit was going
to expire on July 31, 1999 and that a renewal for the permit needs to be submitted to your
office, postmarked no later than February 1, 1999. On behalf of Mrs. Cain, and duly
authorized by; her, BPA Environmental & Engineering, Inc. (BPA) is providing you with the
information requested by your office. The letter from Mrs. Cain authorizing BPA to act as her
Authorized Representative is attached. A brief history of the site's permit application history
is described below. - -
Site History
On May 15, 1995, BPA submitted an application for a General NPDES Permit (NCG 51000)
to discharge treated petroleum contaminated groundwater at the Roscoe's Grocery site.
Because of the presence of di -isopropyl ether (DIPE) and methylene chloride -'in several early
groundwater samples collected at the site, the Water Quality Section determined an Individual
Permit was more appropriate for the treatment system discharge. On December 11, 1995, the
State issued NPDES Permit No. NC 0085014 for the site.
The .treatment system was installed in July -August 1997 and brought online on August 19,
1997. The system has operated almost continually since that time. A chronology of the system
installation, maintenance, and sampling is attached.

s
Mr. Charles H. Weaver, Jr.
January 29, 1999

Request for General Permit Status
Under the Individual Permit, Mrs. Cain was required to sample the effluent weekly for the first
two months and then twice per month thereafter. The existing permit also requires that the
effluent be sampled for Oil and Grease and methylene chloride, and pass a chronic toxicity test
(P/F at 90 %) every quarter. The NPDES Permit sampling requirements and limitations are
summarized in Table 1.
Since the inception of treatment, no methylene chloride has been detected in the effluent
samples above the method detection limit (5 ppb), and no other organic compounds have been
detected in the effluent above a detection limit of .5 ppb. Low levels of oil and grease have
been detected sporadically. The effluent has passed the 90 % P/F level ;of the chronic toxicity
test every quarter the test has been performed. The system effluent sampling results are
summarized in Table 2.
The groundwater at the site has been sampled four times since the system was started in August
1997. Methylene chloride has not been detected in any of the samples during any of these
sampling events. Compounds associated with gasoline continue to be the predominant
contaminant and the levels of those compounds continue to decrease at most sampling locations..
A summary of the groundwater analytical results are shown in Table 3.
Based on the results of the effluent and groundwater sampling events which have taken place
over the last year and a half, we are requesting the Water Quality Section consider changing
the current Individual NPDES Permit to a General NPDES Permit. We spoke with Ms. Karen
Connell, MRO UST Section, and Mr. Mike Parker, MRO Water Quality Section, about
changing to a General Permit and they have both given their verbal approval.
Sampling Requirements
Based on our knowledge of the site, its sampling history, and Mrs. Cain's concern for the
environment, we would like to suggest the following sampling requirements:
(1) Continue to sample the effluent twice per month for the petroleum related compounds,
flow, and pH. Mrs. Cain is very concerned that should the system fail for some reason,
monthly sampling would not provide rapid enough notification that a problem exists.
(2) Continue to sample the effluent by EPA Method 6230-D. We have already established
a sample analysis history using this method. Changing the method may create confusion
due to different detection limits and different compounds analyzed. This is the same

A X
i L
i Mr. Charles H. Weaver, Jr.

Page 3 -
method we use to analyze the groundwater samples. This allows a good comparison
between "what's going in" and "what's coming out" of the system. This method has a
detection limit of .5 ppb for all compounds of concern.
(3) Continue to require weekly inspections of the system. History has taught us that these
systems require continuous maintenance to maintain their efficiency and to stay online.
The most efficient rate of cleanup depends on continuous operation of the system such
that optimum drawdown and steady state flow of contaminants to recovery wells are
maintained. Because the system does not have a continuous rate flow meter, we can
also monitor the flow on.a more regular basis.
(4) Eliminate the Oil and Grease, methylene chloride, and chronic toxicity limitations.
Sludge Management Plan
The Permit is for the discharge of petroleum of petroleum contaminated groundwater. The
system consists of a transfer tank, air stripper, carbon tanks, and associated pumps and
plumbing. No sludge is generated in the treatment process. The old carbon is taken off site
and regenerated.
After reviewing this request, please call me or Ed Hedgecock if you have any questions.
Sincerely yours,
BPA ENVIRONMENTAL & ENGINEERING, INC.

• August 28, 1997 Manually reset system after power outage. Sampled effluent per
NPDES permit (6230D, O/G, pH). Scheduled trip to adjust
calibration on air stripper damper setting using an air velocity
meter. Chan Bryant with Withers & Ravenel traveled to site also.
Engineer needed to calibrate air intake damper for proper
air/water ratio.
• September 1-30, 1997 Compiled groundwater sample data and remediation system
performance information into an Active Groundwater
Monitoring Report. Work associated with the report began
August 19, 1997 when the monitoring wells were sampled.
The report was completed on September 30, 1997 and
mailed to the DWQ on that date.
• September 3, 1997 Traveled to the site to sample effluent per NPDES Permit (6230D,
O/G. and pH), inspected and documented both groundwater and
SVE system performance, repaired roof leak located at SVE
exhaust vent, measured water levels in monitoring wells MW-1,
-2, -3, -4, -5, -7, -10 and pumping wells EW-2 and EW-3.
• September 11, 1997 Traveled to site to sample effluent per NPDES Permit (6230D,
O/G and pH), inspected and documented both groundwater and
SVE system performance, measured water levels in monitoring
wells MW-I, -2, -3, -4, -5, -7, -9, -10, and -11.
• September 19, 1997 Traveled to site to sample effluent per NPDES Permit (6230D,
O/G and pH), inspected and documented both groundwater and
SVE system performance, measured water levels in monitoring
wells MW-1, -2, -3, -4, -5, -7, -9, -10, and -11. Collected an air
sample from the SVE discharge stack for BTEX analysis.
• September 25, 1997 Traveled to site to sample effluent per NPDES Permit (6230D,
O/G and pH), inspected and documented both groundwater and
SVE system performance, transferred 3-55 gallon drums of well
development water to groundwater remediation system transfer
tank, replaced bag filters 1A, 2A and 3A due to sediment
clogging. Ordered case of 50 micron bag filters.

•
October 2, 1997 Traveled to site to sample effluent per NPDES Permit, discovered
that air compressor not working, checked electrical connections,
fuses, etc. but could not diagnosis problem, checked with
Ingersoll-Rand representative for trouble shooting ideas.
Inspected SVE system performance. Noted that silt visible inside
hoses leading to carbon units 1A and 113. Estimated that
groundwater system did not operate from approximately 9 pm
September 28 through October 2.
October 3, 1997 Contacted Ingersoll-Rand and arranged for a service call on
October 9, 1997.
October 8, 1997 Purchased two 40 amp replacement fuses for air stripper in the
event the air compressor problem was due to blown fuses.
October 9, 1997 Met Ingersoll-Rand technician at site, problem diagnosed as burnt
pressure switch on compressor. Pressure switch was replaced and
system restarted at 10 AM. Sampled effluent per NPDES Permit
(6230D, O/G and pH), inspected and documented both
groundwater and SVE system performance, replaced 100 micron
bag filters 1A/B, 2A/B and 3A/B with 50 micron filters to stop
sediment from migrating through system. Backwashed carbon
units 1A and 113-due to sediment seen in transfer hoses. Observed
water blowing from air stripper stack and manually checked and
filled seal ports inside air stripper to correct problem.
• October 14, 1997 Traveled to site to sample effluent per NPDES Permit (6230D,
O/G, pH and Chronic Toxicity) inspected and documented both

LIE
To: G.T.Chen, MRO, Water Quality
Through: NA
From: Tom Belnick, NPDES Unit
Subject: Request from Roscoe Grocery to shift to General Permit Coverage
l"dell .�
I'm attaching a copy of the permittee's request for shift to general permit coverage, as well as
the application package in case you didn't receive. Their letter states that they have already
discussed the request with Karen Connell (MRO-UST) and Mike Parker. Please let me know
what you think.
It looks like this facility originally applied for general permit coverage back in 1995, but was
put into an imdividual permit due to hits of methylene chloride and DIPE (a gasoline
additive). I took a quick look at the data, and it looks like the site history indicates a former
gas station (petroleum contamination), but no activity indicating heavy solvent use (which
generally pushes it into individual permit status). Recent data for groundwater monitoring
wells shows no detections of methylene chloride. Not sure if older hits were due to lab
contamination, which is common for methylene chloride.

BPA No. 0214.002
Dear Mr. Weaver:
2641-G Randleman Road
Greensboro, NC 27406-5159
[phone]
January 29, 1999
On December 21, 1998, your office informed Mrs. Anne Cain that the subject permit was going
to expire on July 31, 1999 and that a renewal for the permit needs to be submitted to your
office, postmarked no later than February 1, 1999. On behalf of Mrs. Cain, and duly`
authorized by her, BPA Environmental &:Engineering, Inc. (BPA) is providing you with the
information requested by your office. The letter from Mrs. Cain authorizing BPA to act as her
Authorized Representative is attached. A brief history of the site's permit application history
is described below.
Site History
On May 15, 1995, BPA submitted an application for a General NPDES Permit (NCG 51000)
to discharge treated petroleum contaminated groundwater at the Roscoe's Grocery site.
Because of the presence of di -isopropyl ether (DIPE) and methylene chloride in several early
groundwater samples collected at the site, the Water Quality Section determined an Individual
Permit was more appropriate for the treatment system discharge. On December 11, 1995, the
State issued NPDES Permit No. NC 0085014 for the site.
The .treatment system was installed in July -August 1997 and brought online on Augusts 19,
1997. The system has operated almost continually since that time. A chronology of the system
installation, maintenance, and sampling is attached. _,, _

Mr. Charles H. Weaver, Jr.

Request for General Permit Status
Under the Individual Permit, Mrs. Cain was required to sample the effluent weekly for the first
two months and then twice per month thereafter. The existing permit also requires that the
effluent be sampled for Oil and Grease and methylene chloride, and pass a chronic toxicity test
(P/F at 90 %) every quarter. The NPDES Permit sampling requirements and limitations are
summarized in Table 1.
Since the inception of treatment, no methylene chloride has been detected in the effluent
samples above the method detection limit (5 ppb), and no other organic compounds have been
detected in the effluent above a detection limit of .5 ppb. Low levels 'of oil and grease have
been detected sporadically. The effluent has passed the 90 % P/F level of the chronic toxicity
test every quarter the test has been performed. The system effluent sampling results are
summarized in Table 2.
The groundwater at the site has been sampled four times since the system was started in August
1997. Methylene chloride has not been detected in any of the samples during any of these
sampling events. Compounds associated with gasoline continue to be the predominant
contaminant and the levels of those compounds continue to decrease at most sampling locations.
A summary of the groundwater analytical results are shown in Table 3.
Based on the results of the effluent and groundwater sampling events which have taken place
over the last year and a half, we are requesting the Water Quality Section consider changing
the current Individual NPDES Permit to a General NPDES Permit. We spoke with Ms. Karen
Connell, MRO UST Section, and Mr. Mike Parker, MRO Water Quality Section, about
changing .to a General Permit and they have both given their verbal approval.
Sampling Requirements
Based on our knowledge of the site, its sampling history, and Mrs. Cain's concern for the
environment, we would like to suggest the following sampling requirements:
(1) Continue to sample the effluent twice per month for the petroleum related compounds,
flow, and pH. Mrs. Cain is very concerned that should the system fail for some reason,
monthly sampling would not provide rapid enough notification that a problem exists.
(2) Continue to sample the effluent by EPA Method 6230-D. We have already established
a sample analysis history using this method. Changing the method may create confusion
due to different detection limits and different compounds analyzed. This is the same

1 �•

Mr. Charles H. Weaver, Jr.

Page 3
method we use to analyze the groundwater samples. This allows a good comparison
between "what's going in" and "what's coming out" of the system. This method has a
detection limit of .5 ppb for all compounds of concern.
(3) Continue to require weekly inspections of the system. History has taught us that these
systems require continuous maintenance to maintain their efficiency and to stay online.
The most efficient rate of cleanup depends on continuous operation of the system such
that optimum drawdown and steady state flow of contaminants to recovery wells are
maintained. Because the system does not have a continuous rate flow meter, we can
also monitor the flow on a more regular basis.
(4) Eliminate the Oil and Grease, methylene chloride, and chronic toxicity limitations.
Sludge Management Plan
The Permit is for the discharge of petroleum of petroleum contaminated groundwater. The
system consists of a transfer tank, air stripper, carbon tanks, and associated pumps and
plumbing. No sludge is generated in the treatment process. The old carbon is taken off site
and regenerated.
After reviewing this request, please call me or Ed Hedgecock if you have any questions.

Dear Mrs. Cain:.
Our records indicate that NPDES Permit No. NCO085014 was
issued on December 11, 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 are Pages 4-6.
Pages 4-6 sets forth the effluent limitations and monitoring
requirements for your discharge. Your discharge 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
i 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
I
a sample of the "Effluent"::.-.r.eporting 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.
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,

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 violation (and/or criminal penalties)
maybe assessed for such violations. If you find at any time that
you are unable to comply with the terms and conditions of the -
Permit, you should contact this Office immediately. A'Consent
Order may be necessary while pursuing action to obtain compliance.
As a final not%e, 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 1 of the Permit. Also
note that NPDES Permits are not transferable. If you, as the
Permittee,. cease to need this Permit, 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

Description of Discharge
This application was originally for a general permit; however, the presence of methylene
chloride in the groundwater prevents the applicant from receiving a general permit. The treatment
system will discharge into an unnamed tributary to North Little Hunting Creek. The effluent limits
were developed based on zero flow conditions due to the small drainage area.
Monitoring frequencies are based on those in the general permit.
Drainage Area is approximately 0.0 square miles
7Q10=0cfs
Due to extremely low flow, effluent limits will be based on a 7Q10 and Qaverage dual to zero.

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

6. Concentration Measuremen
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

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 meanof 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
I 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

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 Sample
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 tetweeneffluent 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 theproduct 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.

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 fora 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).
i
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 11
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 toprevent 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 H, B. 2. of this

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 11
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 udhzation/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,
