ACUTE TOXICITY TESTING REQUIREMENT
Daphnid 48 hr - Monitoring for Episodic Events
The permittee shall conduct FIVE acute toxicity tests using protocols defined 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 Daphnia p&a or Ceriodayhnia 48 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 fast five
discrete discharge events after the effective date of this permit.
The parameter code for this test if using Daphniayulex is TAA3D. The parameter code for this test
if using Oeriodaphnia is TAA3B. 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: Technical Services 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 a failure of permit condition.

SUBJECT: Comments regarding Texaco USA Greensboro objections
NPDES No. NC0022209, Guilford County
I have reviewed the letter from Texaco USA requesting relief from several
proposed parameters in the permit and a reduction in monitoring requirements.
It should be noted that these parameters are being applied to contaminated
runoff from all tank farms, which recent studies have shown to be of concern.
The parameters should remain in the permit as recommended. The facility may,
after 12 months of monitoring, rerequest an evaluation of these requirments.
With regard to the facilities comments on phenols, the limit must remain
intact. The purpose of the limit is to protect the downstream water supply from
taste and odor problems associated with phenolic compounds. The state standard
for phenols is 1.0 ug/l for all WS waters. This facility has already been given
a break since their limit reflects protection of the standard at the headwaters
of Highpoint Lake rather than at their outfall (which has no dilution). There
are 13 tank farms discharging to this portion of the basin and, therefore, it is
important that phenolic compound discharges be held to a minimum.
The settleable solids and turbidity limitations are applied to all storm -
water or retaining pond discharges. These limits reflect state standards and
regulations intended to protect aquatic life instream.
Please let me know if further clarification is required.

RE: NPDES Permit w0 7-z� O `�
Texaco Greensboro Terminal
Dear Mr. Mouberry:
71�o
In reference to draft permit sent to our attention, we request
the permit information and modifications outlined herein.
}
The draft permits indicates a mass limit for phenols at a daily
average of 0.001 ##/day. Even though this mass limit is more
reasonable than the previous concentration limit, we do fee]. this
will present compliance problems as we must limit discharge
volumes under the proposed effluent limit. In this respect, we
request a permit modification to allow discharge of stormwater
from the tank basin, subject to Best Management Practice (BMP)
and defined as removal of any visible sheen prior to discharge.
This, of course, will not include oil/water separator or tank
water bottom effluent.
As you know, "phenols" include a number of compounds, some
of which are natural occurring. We are requesting a permit
revision to specify only "phenol" as a permit parameter. The
testing for phenol is quite expensive,' therefore we request a
revised Monitoring Requirement -Measuring Frequency of once a
month for the phenol effluent parameter.
The settleable solids limit at 0.1 ml/1 is our second fgajor
concern. This is a permit limitation which h-as not been imposed
previously in any petroleum marketing terminal NPDES permit to
our knowledge. The draft permit does not specify either the
analytical method to be used or required settlement time, and we
have no information from your office which supports this permit
limitation. It is our belief that this is an inappropriate limit
for a petroleum terminal, and we request deletion of the effluent
limit for settleable solids.

Mr. Arthur Mouberry
June 30, 1988

Thirdly, the turbidity limit of 50 NTU has not been specified on
other NPDES permits to our knowledge. We therefore have no data
available to assess our ability to comply with this permit limit.
We request that you provide us with the basis for this permit
limitation.
Your consideration on the above matters will be appreciated.
If there are further questions, please call Mr. D. E. Arnold,
404-329-5408.
Sincerely,
G. A. Hamilton, Jr.
