Memorandum
To: Susan Robson
From: Carla Sanderson"
Through: Ruth Swanek
Subject: Amoco Oil Company
NPDES Permit No. NC0005185
Mecklenburg County
Comments on Draft
This memorandum is in response to comments sent to the Instream Assessment Unit
(October 18, 1993) concerning the Draft Permit for Amoco Oil. After reviewing Amoco's
comments I will assume responsibility for answering comment number 2 concerning the
phenol limit imposed on outfalls 002, 003, and 006. Amoco requests to have the limitation
on phenol changed from concentration to mass based limit. This request is not an option
for the facility since the discharge is to WS-IV waters. Per 15A NCAC 2B.0211 (f) (3)
(D), the discharge of phenolic compounds cannot be greater than 1.0 ug/1 to protect water
supplies. If the limit is given as a mass (lbs/da), then at certain discharge flows, the
concentration of 1.0 ug/1 could be violated. Therefore, the limits for phenols at the above
mentioned outfalls should remain 1.0 ug/1
Let me know if you need any further information.

Amoco Charlotte Terminal - Comments on
#NC0005185
I have reviewed the subject proposed NPDES permit and would
make the following comments:
1) Outfall numbers/locations: because the terminal is located on
a topographic divide between two different tributaries of the
Catawba River and individual outfall points discharge to
differjent tributaries, there has been a good deal -of
confusion over which outfall discharges to which tributary.
This confusion was compounded by a map which has labels for
outfalls 002 and 003 transposed. This map was originally
submitted by Law Environmental in 1989 as part of an
application for NPDES permit for outfall 005 and was
resub fitted as part of the application for renewal of NPDES
permit for outfalls 001, 002, 003, and 004 on March 28, 1991.
I have reviewed the existing documentation back to 1985 and
would like to offer the following proposed wording for
variol.�s sections of the draft NPDES permit. This wording will
correct the errors caused by the confusion.
Draft NPDES Permit
like to
Page 1, third paragraph
"to receiving waters designated as an unnamed tributary to Gum
Branch for outfalls 003 and 004, and an unnamed tributary to
Long Creek for outfalls 002, 005, and 006 in the Catawba River
Basin"

Page 2
Page 2, first paragraph
"1. Continue to operate oil/water separators in conjunction
with outfalls 002 and 004, continue to discharge stormwater
from outfalls 002, 003, and 006, and, after receiving an
Authorization to Construct from the Division of Environmental
Management, construct and operate a groundwater remediation
project for outfall 005 consisting of an oil/water separator,
granucLar activated carbon fluid bed reactor, two multimedia
filters (inparallel),clarifier, filter backwash tank,
nutrient addition, and oxygen generation at a facility located
at NC1Highway 27, near the town of Thrift, Mecklenburg County
(See Part III of this Permit), and"
Page , second paragraph
2. Discharge from said treatment works at the location
on the attached map into an unnamed tributary to Gum Branch
for outfalls 003 and 004, and into an unnamed tributary to
Long Creek for outfalls 002, 005, and 006 which are both
class:f ied Class WS IV waters in the Catawba River Basin.
2) Amoco requests that the discharge limitations on phenols for
the outfalls be converted from a daily max. concentration
basis to a daily max. mass limit. Other NPDES permits for
termi als in the state (including NPDES Permit #NC0003671
for our Greensboro Terminal) have been converted to allow
better control over the actual physical mass of phenols that
are discharged to the receiving stream during each day. This
change would benefit the receiving stream in that it would
limit the actual mass discharged to the stream on any given
day.
Thank you for the opportunity to comment on the proposed NPDES
permit. lease contact me at [phone] if you have any
questions.

SPECIAL INSTRUCTIONS OR CONDITIONS
Permit must contain flow monitoring requirement such that all volumes of wastewater leaving the
facility are monitored. If continuous monitoring is not feasible, then discharger shall record the
approximate times that discharge began and ended, along with instantaneous flow at the time of
effluent sampling.
Monitoring for all toxicants should be performed during the first five discrete discharge events
(and annually thereafter) after the effective date of the NPDES permit. Monitoring should occur at
the same time that the whole -effluent toxicitiy sample is collected during the discharge event
(samples should be collected within 24 hours of the beginning of the event).
BTEX parameters should be monitored using an EPA approved method to a detection level of at
least 1 ppb.
A reopener should be placed in the permit to allow for additional limits on these or other toxicants
should the whole effluent toxicity test indicate toxic effects.

ACUTE TOXICITY MONITORING (EPISODIC)
The permittee shall conduct FIVE acute toxicity tests using protocols defined as definitive in
E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales
promelas) 24 hour static test, using effluent collected as a single grab sample. Effluent samples
for self-monitoringpurposes must be obtained below all waste treatment. Sampling and
subsequent testinioccur during the first five discrete discharge events after the effective date
of this permit. After monitoring of the first five toxicity tests, the permittee will conduct one test
annually, with the annual period beginning in January of the next calendar year. The annual test
requirement must be performed and reported by June 30. If no discharge occurs by June 30,
notification will be made to the Division by this date. Toxicity testing will be performed on the
next discharge event for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DEM Form AT-1 (original) is
to be sent to a following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Rd.
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in kssociation with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection o the waste stream.
Should any te4t data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test.
Failure to subTit suitable test results will constitute noncompliance with monitoring requirements.

MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Miscellaneous information pertinent to the renewal or new permit for this discharge. Include
relationship to the Basinwide Management Plan.
SPECIAL INSTRUCTIONS OR CONDITIONS
Permit must contain flow monitoring requirement such that all volumes of wastewater leaving the
facility are monitored. If continuous monitoring is not feasible, then discharger shall record the
approximate times that discharge began and ended, along with instantaneous flow at the time of
effluent sampling.
Monitoring for all toxicants should be performed during the first five discrete discharge events
(and annually thereafter) after the effective date of the NPDES permit. Monitoring should occur at
the same time that the whole -effluent toxicitiy sample is collected during the discharge event
(samples should be collected within 24 hours of the beginning of the event).
BTEX parameters should be monitored using an EPA approved method to a detection level of at
least 1 ppb.
A reopener should be placed in the permit to allow for additional limits on these or other toxicants
should the whole effluent toxicity test indicate toxic effects.

Facility Name Amoco Oil Company -Charlotte Terminal_ Permit # NC0005185 _ Pipe # 003 _
ACUTE TOXICITY MONITORING (EPISODIC)
The permittee shall conduct FIVE acute toxicity tests using protocols defined as definitive in
E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales
promelas) 24 hour static test, using effluent collected as a single grab sample. Effluent samples
for self -monitoring purposes must be obtained below all waste treatment. Sampling and
subsequent testing will occur during the first five discrete discharge events after the effective date
of this permit. After monitoring of the first five toxicity tests, the permittee will conduct one test
annually, with the annual period beginning in January of the next calendar year. The annual test
requirement must be performed and reported by June 30. If no discharge occurs by June 30,
notification will be made to the Division by this date. Toxicity testing will be performed on the
next dischargevent for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DEM Form AT-1 (original) is
to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Rd.
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any te4 data from either these monitoring requirements or tests performed by the North
Carolina Divis�on of Environmental Management indicate potential impacts to the receiving stream,
this permit ma be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Fail to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test.
Failure to submit suitable test results will constitute noncompliance with monitoring requirements.

No parameters are water quality limited, but this discharge may affect future allocations.
MISCELLANEOUS INFORMATION & SPECIAL CONDITIONS
Miscellaneous information pertinent to the renewal or new permit for this discharge. Include
relationship to the Basinwide Management Plan.
SPECIALINSTRUCTIONS OR CONDITIONS
Permit must contain flow monitoring requirement such that all volumes of wastewater leaving the
facility are monitored. If continuous monitoring is not feasible, then discharger shall record the
approximate times that discharge began and ended, along with instantaneous flow at the time of
effluent sampling.
Monitoring for all toxicants should be performed during the first five discrete discharge events
(and annually thereafter) after the effective date of the NPDES permit. Monitoring should occur at
the same time that the whole -effluent toxicitiy sample is collected during the discharge event
(samples should be collected within 24 hours of the beginning of the event).
BTEX parameters should be monitored using an EPA approved method to a detection level of at
least 1 ppb.
A reopener should be placed in the permit to allow for additional limits on these or other toxicants
should the whole effluent toxicity test indicate toxic effects.
WASTELOAD SENT TO EPA? (Major) (Y or N)
(If yes, then attach schematic toxics spreadsheet, copy of model, or if not modeled, then old
assumptions that were made, and description of how wasteload fits into basinwide plan.)
Additional Information attached? (Y or N) If yes, explain with attachments.

ACUTE TOXICITY MONITORING (EPISODIC)
The permittee hall conduct FIVE acute toxicity tests using protocols defined as definitive in
E.P.A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to Freshwater and
Marine Organisms." The monitoring shall be performed as a Fathead Minnow (Pimephales
promelas) 24 hour static test, using effluent collected as a single grab sample. Effluent samples
for self -monitoring purposes must be obtained below all waste treatment. Sampling and
subsequent tes g will occur during the first five discrete discharge events after the effective date
of this permit. After monitoring of the first five toxicity tests, the permittee will conduct one test
annually, with the annual period beginning in January of the next calendar year. The annual test
requirement must be performed and reported by June 30. If no discharge occurs by June 30,
notification will be made to the Division by this date. Toxicity testing will be performed on the
next discharge event for the annual test requirement.
The parameter code for this test is TAE6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DEM Form AT-1 (original) is
to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Rd.
Raleigh, N.C. 27607
Test data shall complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of a waste stream.
Should any test data from either these monitoring requirements or tests performed by the North
Carolina Division of Environmental Management indicate potential impacts to the receiving stream,
this pemut may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organists survival and appropriate environmental controls, shall constitute an invalid test.
Failure to submit suitable test results will constitute noncompliance with monitoring requirements.

Comments from the Mooresville Regional Office
This Office has reviewed the proposed WLA for the Amoco
Company, NPDES Permit No. NC0005185. The review
cates some confusion regarding the source and treatment
tormwater for the various outfalls. The following lists
current status of each outfall:
all 001: Stormwater from fuel loading area. Has been
connected to outfall 002 and will no longer
be used.
Outf 11 002: Consist of stormwater from the fuel loading
area (formerly 001) and stormwater from diked
containment areas. Only stormwater from the:' -
fuel loading area is treated via the
oil/water separator. r'""
Outf
Out f
Out f
Out f
11 003:
11 004:
Consist of stormwater from diked containment
area, no treatment provided. -`'
Proposed discharge from railcar loading area:;
The discharge will become active in the near
future, probably before permit is renewed.
Treatment will consist of an oil/water
separator which is already in place.
11 005: Proposed groundwater remediation.
11 006: Stormwater from diked containment area that
was formerly GNC Energy Corp.'s property. An
oil/water separator is in place; however, the
oil/water separator will not be used in the
immediate future. The GNC Energy Corp.'s
fuel loading area has been dismantled.
It is recommended that all stormwater outfalls have
epis•dic monitoring (first five discrete discharge events
and annually thereafter) for benzene, toluene, ethylbenzene,
xyle e, MTBE, and toxicity. Monitoring for other parameters
show d be to 2/month for stormwater from fuel loading areas
and /year for stormwater from diked containment areas.
Atta hed are comments from the Mecklenburg County Department
of E vironmental Protection (MCDEP). Technical Support
Branch should evaluate MCDEP's request for in -stream
monitoring.

Dear Ms. Smith:
Ca
RE: Amoco NPDES Permit Renewal
and Paw Creek oil/Water Separators
Thank you for requesting our input on the above referenced
permit renewal and surface water dischargers in the Paw Creek
area.
The Mecklenburg County Department of Environmental
Protection (MCDEP) is conducting a special surface water duality
monitoring project around Paw Creek and has some data available
(attached) for your use in staff reports for permit renewals if
helpful. we will provide you a complete report when the study is
concluded, hopefully later this month.
MODE is very concerned about the quality of effluent from
the permuted dischargers and offers the following comments:
1.
Permits should require as a minimum monitoring for the
following on the effluent from oil/water separators (in
addition to the standard flow, oil and grease total
suspended residue, etc.):
Benzene
(Ethylbenzene
Toluene
Xylene
MTBE
Chronic Toxicity
Organics
7nd include limits on these parameters if possible.

I ha
e some information for you on this permit:
1. Outfall 001 is now tied into 002 so that the flow for 001 goes into the oil/water separator.
So now we have only 5 outfalls.
2. Tank storage capacities for the outfalls:
' 001 2 million gallons+ -- tivfiti f41I 00 !
002-1 5 million gallons+
003-� 5 million allons+
006- 5 million gallons+
4)004 is just drainage from loading rack area.
005 is the groundwater remediation project.
If you have any questions, just give me a call.
Tha,rilcs!
