SUBJECT: Compliance Evaluation Inspection
NC General Wastewater Permit NCG510000 for Discharge of Wastewater from a
Groundwater Remediation System
Certificate of Coverage: NCG510521 for Bill's Convenient Mart, Oak Ridge,
Guilford County, North Carolina
Dear Mr. Barrow:
Jim Gonsiewski of the NC Division of Water Resources (DWR), Winston-Salem Regional Office
(WSRO), visited your facility on January 22, 2021 and met with Mr. Danny Oldham of Pyramid
Environmental to perform a compliance evaluation inspection of your facility's groundwater
remediation system. Details of that inspection are included on the attached EPA Water Compliance
Inspection Report.
The following items were noted during the inspection:
The remediation system at the site operated until December 20, 2017 when activity at the site was
terminated due to a directive by the NCDEQ Underground Storage Tank (UST) section. Currently
ten wells are located on the site (seven monitoring wells and three recovery wells). These wells,
along with a community water supply well, are sampled semi-annually. The system effluent was
last sampled on July 27, 2017. Laboratory analytical results for this sampling event indicated all
analyzed constituents were below laboratory reporting limits. The remediation system and the
building in which it is located appear to be in good condition.
The outfall for a 3-inch PVC effluent pipe that transports treated water from the remediation system
to a drainage feature which empties into an unnamed tributary of Beaver Creek is located in the
wooded area to the west of the remediation system. The pipe was observed to be in good condition
with no visible cracks or breaks.

NPDES Permit NCG510000
PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
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.
Calendar Day
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.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval
between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite
samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: 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 treasured at the time of individual sample
collection, or
Variable time/constant volume: 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
preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
Influent samples shall not be collected more than once per hour.
(3)
Page8of19

NPDES Pemut NCG510000
Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous. flow measurement
Flow monitoring that occurs 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.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants teasured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest"daily discharge" during the calendar month.
Dailv Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWR or "the Division".
The Division of Water Resources, Department of Environment and Natural Resources.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA

Facility. Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level ]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform or other bacterial parameters or indicators, the geometric mean of such discharges.
Page 9 of 19

The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse effects, if
the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph c.
(1) of this section.
(3)
5. Upsets
a. Effect of an upset [40 CFR 122.41(n)(2)]: An upset constitutes an affirmative defense to an action brought for
noncompliance with such technology based permit effluent limitations if the requirements of paragraph b. 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.
b. Conditions necessary for a demonstration of upset: Any Pennittee 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;

of altemate 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 representative of the permitted discharge.
Samples collected at a frequency less than daily shall be taken on a day and time that is representative of the
discharge for the period 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 [40 CFR 122.41(j)].
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 (MR 1, 1.1, 2, 3) or alternative forms approved by the
Director, postmarked no later than the last calendar day of the month 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 case of a new
facility, on the last day of the month following the commencement of discharge. Duplicate signed copies of these,
and all other reports required herein, shall be submitted to the following address:
NC DENR / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
3. Flow Measurements
Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected
and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The
devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements is consistent
with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a
maximum deviation of less than 10% from the true discharge rates throughout the range of expected discharge
volumes. Flow measurement devices shall be accurately calibrated at a minimum of once per year and maintained
to ensure that the accuracy of the measurements is consistent with the accepted capability of that type of device.
The Director shall approve the flow measurement device and monitoring location prior to installation.
Once -through condenser cooling water flow monitored by pump logs, or pump hour meters as specified in Part I of
this permit and based on the manufacturer's pump curves shall not be subject to this requirement.
4. Test Procedures
Laboratories used for sample analysis must be certified by the Division. Permittees should contact the Division's
Laboratory Certification Section (919 733-3908 or http://portal.ncdenr.org/web/wq/lab/cert) for information
regarding laboratory certifications.
Facilities whose personnel are conducting testing of field -certified parameters only must hold the appropriate field
parameter laboratory certifications.
Test procedures for the analysis of pollutants shall conform to the EMC regulations (published pursuant to NCGS
143-215.63 et. seq.), the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section
304(g), 33 USC 1314, of the CWA (as amended), and 40 CFR 136; or in the case of sludge use or disposal,
approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been
specified in this permit [40 CFR 122.41].
To meet the intent of the monitoring required by this pennit, 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.

Technical Bulletin
For General Permit NCGSI0000
' 4
Reined .!, a rou . titer
Revised
September 15, 2016
Coverage Under This Permit
This general permit covers point source discharges of
remediated petroleum contamination (i.e., gasoline, diesel
fuel, aviation fuel, kerosene, or fuel oil) to surface waters that
discharge less than (<) 0.25 MGD. Such wastewater
discharges include:
• Groundwater remediation
• Well construction and similar wastewaters
• Other construction activities (e.g., dewatering)
Wastewater contaminated with pollutants other than
petroleum compounds (e.g., solvents, pesticides) are
excluded from this general permit, and will require an
individual NPDES permit to discharge to surface waters.
Also, proposed discharges to receiving waters classified as
ORW or HQW are excluded from general permit coverage.
NOTE: Discharge of groundwater generated by well
construction or other construction activities that are not
contaminated are deemed to be automatically permitted per
15A NCAC 2H.0106 (f) (7).
Changes in Reissued General Permit
The previous General Permit expired September 30, 2016.
Several important changes from the previous version of this
permit are:
• Total Lead. Final limits for Total Lead are 3 µg/L for
freshwater and 8.1 µg/L SB/SC Class. An interim Total
Lead limit of 25 µg/L will be used for compliance
purposes until October 1, 2020. By this date, if
compliance with the new limits cannot be maintained,
the permittee shall apply for an individual permit.
• Total Hardness (as CaCO). For freshwater discharges, if
any effluent Total Lead sample exceeds the final limit of
3.0 µg/L, quarterly sampling for hardness shall be
immediately initiated and performed in conjunction with
Total Lead sampling.
• Toluene. The saltwater limit for aquatic life protection is
changed from 215 ug/l to 370 ug/I based on updated
EPA ECOTOX & RAIS 8/07 data.
• Total Xvlenes. The saltwater limit for aquatic life of 370
µg/L is removed because IRIS, ECOTOX & RAIS 6/12
indicate limited data. A limit of 450 µg/L is added for
trout class waters based on IRIS, ECOTOX & RAIS
6/12.
• Total Recoverable Phenolics. Please note the parameter
description and parameter code is changed from Total
Phenol [346694] to Total Recoverable Phenolics
[32730].
• Oil and Grease. The previously used test method for Oil
& Grease targets animal and vegetable fats, oils and
greases typical of 100% domestic discharges. Method
1664 —STG-ISM [silica gel transfer -hexane extraction
method] targets non -polar oil and grease more typical of
industrial waste discharges.
• MTBE. The human health limit of 1500 µg/L is added.
• Flow. For flows greater than or equal to (>_) 0.05 MGD
and less than 0.25 MGD, monitoring is now weekly.
Flows greater than or equal to (>—) 0.25 MGD are
excluded from coverage under this General Permit.
• Monitoring Frequency for parameters. For flows greater
than or equal to (>—) 0.05 MGD and less than (<) 0.25
MGD, monitoring is now Monthly.
Key Permit Requirements
• Effluent monitoring of parameters specified in Part I,
Section A. Quarterly monitoring is required for flows
less than (<) 0.05 MGD. For flows greater than or equal
to (>_) 0.05 MGD, monitoring is monthly. Flows greater
than or equal to (>>) 0.25 MGD are excluded from
coverage under this General Permit. Six separate
monitoring pages are included in Part I, Section A:
Flows <0.05 MGD
A. (1). gasoline
A. (2). diesel fuel, aviation fuel, kerosene & fuel oil
A. (3). combined releases
Flows >0.05 MGD and <0.25 MGD
A. (4). gasoline
A. (5). diesel fuel, aviation fuel, kerosene & fuel oil
A. (6). combined releases
• All samples should be collected before the effluent joins
or is diluted by anyother wastestream, water or
substance. [Part II, Section D. (1)]
• Proper operation and maintenance of the system to
achieve compliance with the conditions of the permit.
[Part II, Section C. (2.)]
• Solids, sludges, filter backwash or other pollutants
removed in the course of treatment shall be disposed
properly to prevent materials from entering waters of the
State. [Part II, Section C. (6.)]
• The permittee shall give notice to the Division of any
planned physical alterations or additions to the system
that could significantly increase the quantity of

pollutants discharged or introduce new pollutants to the
discharge. [Part II, Section E. (2.)]
• Any exceedances of the permit limits must be reported to
the Division within 24 hours from the time the permittee
becomes aware of the circumstances. [Part 11, Section E.
(6.)]
• Minimum Treatment System Requirements include: air
stripper and/or activated carbon; and oil water separator
(if free product available). Permittee should consider the
need for surge tanks and filters. It is permittee's
responsibility to design a treatment system that will
comply with permit limits.
Frequently Asked Ouestions
1) Do I need to employ a certified wastewater treatment
plant operator to manage and run the system?
Not at this time. The Division's Technical Assistance
and Certification Unit does not currently plan to classify
these types of remediation facilities for the purposes of
requiring a certified operator. The requirement remains
in the permit at this time with clarification, in the event
that classification is assigned at a future time.
2) Where do I find my stream classification?
The stream classification, i.e. WS-IV, C, Tr, etc. can
usually be found in the Certificate of Coverage. If you
are unsure of your stream classification, you can contact
the DWR Water Quality Permitting Section.
3) Does a certified lab need to be used to analyze
samples?
Yes, a North Carolina certified lab must be used to
perform analytical monitoring. A list of certified labs is
available from the Division.
4) What If I Sell My Business Or The Name of My
Business Changes?
The Division views changes of name or ownership as a
minor permit modification and requires the Director's
approval. Name and ownership changes require you to
complete a Name/Ownership Change Form. The forms
are available by contacting the DWR Water Quality
Permitting Section or via the website (see Contact
Information below).
5) How do I apply for coverage or rescind coverage
under this General Permit?
This General Permit expires on September 30, 2021.
New applicants must submit a completed NOI and
applicable permit fees. The application forms are
available by contacting the DWR Water Quality
Permitting Section or via the website (see Contact
Information below). If an existing permittee plans to
eliminate the remediation activity and no longer requires
coverage under this General Permit, the permittee will
need to request rescission of permit coverage from the
NPDES Unit by letter request.
6) Do I need to submit the monitoring results to the
Division?
At this time, the submission of monitoring reports for
this permit is not required. There are no standardized
Discharge Monitoring Reports (DMRs) associated with
this permit. Submittal of monthly Discharge Monitoring
Reports (DMRs) shall not be required except upon
demand by the Division. Part I, Section A supersedes the
requirement for submitting monthly Discharge
Monitoring Reports (DMRs) specified in Part II, Section
D (2) of this permit. Even though the submittal of the
monthly monitoring reports to the Division is suspended,
all monitoring requirements remain. The data will be
maintained on site for a period of three years. However,
as per Part II, E.6, violations of any permit limitation
must be reported within 24 hours from the time the
permittee becomes aware of the circumstances.

Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Jim Gonsiewski of the NC Division of Water Resources (DWR), Winston-Salem Regional Office
(WSRO), visited the facility on January 22, 2021 and met with Mr. Danny Oldham of Pyramid
Environmental to perform a compliance evaluation inspection of the facility's groundwater remediation
system.
The following items were noted during the inspection:
The remediation system at the site operated until December 20, 2017 when activity at the site was
terminated due to a directive by the NCDEQ Underground Storage Tank (UST) section. Currently ten
wells are located on the site (seven monitoring wells and three recovery wells). These wells along with
a community water supply well are sampled semi-annually. The system effluent was last sampled on
July 27, 2017. Laboratory analytical results for this sampling event indicated all analyzed constituents
were below laboratory reporting limits. The remediation system and the building in which it is located
appear to be in good condition.
The outfall for a 3-inch PVC effluent pipe that transports treated water from the remediation system to
drainage feature which empties into an unnamed tributary of Beaver Creek is located in the wooded
area on the west side of the site. The pipe was observed to be in good condition with no visible cracks
or breaks.
