SUBJECT: Revision to Crown Central Petroleum Permit.
NPDES Permit No. NC0046531.
Mecklenburg County
Technical Support agrees with Crown Central Petroleum's
request for permit limits applying only to outfall 003.
Since continuous monitoring of the discharge from outfall 003
is not feasible, the discharger shall record the approximate
times the discharge began and ended, along with the
instantaneous flow at the time of the effluent sampling.
Toxicity testing must be conducted during the first five
discrete discharge events as stated in the permit. Quarterly
monitoring for intermittent discharges is not acceptable.
There should be no discharge of tank bottom water from
outfalls 001 and 002. Water should be hauled off -site for
proper disposal until an air stripper is installed.

FROM: D. Rex Gleason
PREPARED BY: G. T. Chen ee;e44/
SUBJECT: Request for Modification on Draft Permit
Crown Central Petroleum Corporation
NPDES Permit No. NC0046531
Mecklenburg County; -`e.
This Office has reviewed the letters dated May 7 and June 5,
1990 from Mr. John R. Funk, Manager of Distribution/Coordination/
Regulatory Affairs, Crown Central Petroleum Corporation. In his
letters, Mr. Funk requests that all monitoring requirements in the
Draft Permit be modified to apply only to Outfall Serial Number 003
(Discharge Point III), that requirements for Acute Toxicity and
Organics tests also be modified to apply to 003 on a quarterly basis
for the first year, and that requirements for in -line metering
devices for the three (3) outfalls be exempted. Mr. Funk advises
that Crown Central Terminal in Charlotte has only one oil/water
separator that handles surface runoff and loading rack incidents.
Wastewater generated from the loading rack area is discharged via
003. Although there are two other separators at the terminal (as
noted in the staff report dated December 20, 1989 by G. T. Chen),
they are connected directly to tank systems to handle tank bottom
water. Mr. Funk advises that Crown Central will not discharge tank
bottom water via any facility outfall in the future. In fact, Crown
Central is scheduled to install an air stripper tower in 1991 to
handle tank condensate. In the interim, tank bottom water will be
hauled off -site for proper disposal. Because of the intermittent/
infrequent discharge from the tank farm facilities, it would be too
costly to install in -line metering devices for all three outfalls.
Mr. Funk proposes alternatives for flow measurement at each outfall
location.
In view of the fact that the Crown Central Terminal will not
discharge tank bottom water through Outfalls 001 and 002 (Discharge
Points I & II) which are used for storm water runoff only, a
potential chronic adverse impact on the receiving water (an unnamed
tributary to Gum Branch - Class C waters) does not appear likely.
Therefore, we recommend that all Permit monitoring requirements in
the Draft Permit be modified to apply to only the discharge from

Page Two
Outfall 003; that Acute Toxicity and Organics tests requirements
also be modified to apply to Outfall 003, with sampling of the first
five (5) discrete discharge events after the Permit becomes
effective; and that the requirement for in -line metering devices for
all outfalls be exempted.
Should you have any questions regarding this matter, please
advise.

Re: NPDES No. NC 0046531
Dear Mr. Overcash:

As a follow-up to my May 7, 1990 letter concerning the DRAFT PERMIT language
for NPDES No. 0046531, there appears to be a need to further clarify Crown's
request found on page two of my letter. Recently, Mr. C. T. Chen of your
Mooresville, North Carolina office contacted our Terminal Superintendent,
Mr. W. F. Reid, to discuss testing requirements.
Crown would ask the State to consider using outfall DPIII as the representative T
outfall for all facility monitoring/testing. Outfall DPIII contains the sole -'
facility oil/water separator and is influenced by rainfall/storm water run-off C l
from the tank farm and the loading rack areas. Outfalls DPI and DPII are used a.
to handle storm water run-off exclusively. As Mr. Reid indicated to Mr. Chen,
Crown will not as a matter of practice discharge tank bottom water through any
facility outfall. It is our intention to haul tank water bottoms off -site for
proper disposal and/or process water through an air stripper tower (installation
scheduled for 1991).
It was also recommended that Acute Toxicity and Organics Testing be conducted
once per quarter per outfall as opposed to testing the first five discrete
discharges from each outfall. The intent of our proposal would be for Crown
to conduct quarterly Acute Toxicity and Organics Testing for outfall DPIII.
If the proposed language is acceptable, Crown would conduct Acute Toxicity and
Organics Testing on four occasions for the first year of the permit as opposed
to fifteen occasions.

As discussed during our telkphone conversation on ay 4,
the DRAFT PERMIT language for NPbES No. 0046531 is acce table
with the following exceptions and/or points of clarification
duly noted. The Supplement to Permit Cover sheet specifies
the operation of three (3) oil -water separators. The facility
actually has one oil -water separator to handle storm water
runoff and loading rack activity. The two other separators
are tied directly into tank systems for handling tank water
bottoms and do not handle storm water runoff.
Flow measurement data will be recorded by the development
of rain gauges for each outfall location and/or the development
of a gallon per hour discharge rate based on size of discharge
piping/ valves and duration of discharge. Due to the
intermittent/infrequent discharges from this facility, it is
our contention that the cost of in -line metering devices for
the three outfalls would be prohibitive.
It is our understanding that the facility has been
classified as a Class I facility therein requiring a Certified
Operator. For your information, our Terminal Superintendent,
Mr. Floyd Reid, has been in contact with the State and is
scheduled to take the required certification examine.

SHEET NO 2'
Mr. Dale Overcash
May 7, 1990
The Acute Toxicity and Organics Testing requirements
dictate that testing occur during the first five discrete
discharge events after the effective date of thig permit.
Due to the costs associated with acute toxicity and organics
testing, Crown would ask the State to consider a reduction
in the number of sampling/testing events required and/or limit
sampling/testing to the outfall (DPIII) fed by the oil -water
separator. In respect to the discharge water being comprised
almost exclusively from rainfall/storm water runoff it is
recommended that acute toxicity and organics testing be
conducted throughout the year on a quarterly basis.
As indicated in our conversation, Crown did not receive
Part III, Condition H regarding Organics Testing Requirements.
Please advise if you have any questions.

ACUTE TOXICITY TESTING REQUIREMENT
Fathead Minnow 24 hr - Monitoring (Annual) for Episodic Events
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 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
P.O. Box 27687
Raleigh, N.C. 27611
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 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 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 submit suitable test results will constitute noncompliance with monitoring requirements.
