----------------------------- COMMENTS -----------------------------------
This discharge (001) is an existing/renewal. The facility recently
received an A to C, so no compliance data is available.
Recommend renewal with existing limits.
Dilution ratio is high, so no Fecal limit or NH3-N limit will be applied.
Outfall 001 and 002 eventually connect to the same pipe and discharge at
the same point. The facility should be required to monitor each outfall
separately before the pipes are combined.

Discharge is storm water runoff. Limits and monitoring
requirements per SOP. All volumes of wastewater leaving the facility
should be monitored. If continuous monitoring is not feasible, then dis-
charger shall record appx. time that discharge began and ended, along with
the instantaneous flow at the time of effluent sampling.
Recommend monitoring for the attached list of parameters on the same
schedule as the toxicity test. Monitoring and tox samples (grab) should
be taken at the same time, within 24hrs of beginning of the discharge
event. A reopener clause should be placed in the permit to allow for
limits to be placed on toxicants should the whole eff tox test indicate
toxic effects.
As per outfall 001, sampling should take place before outfall 001 and 002
are combined.

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.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
This facility discharges runoff from small fuel storage/transfer area. This facility is-Sasically a
large truck stop. Technical Support concurs with WiRO's recommendation to delete toxicity
testing requirement and the organics testing. [ref. 5/15/91 memo from A. Preston oward].
However, Tech Support suggests a grab sample be taken of the facility's effluent, perhaps
annually, to test for toxicty (in-houseohould the facility show acute toxicity, organics
monitoring would then be required. LL,. w<< two? 4,
WLA was held due to question in SOP regarding these types of facilities.

PART IV - EVALUATION AND RECOMMENDATIONS
This small volume discharge should have little impact on the
receiving waters if it meets existing secondary effluent limits.
The company has installed catch basins and an oil/water separator
to collect stormwater in the vicinity of the covered fuel bays in
an attempt to improve the quality of stormwater leaving the site.
It is recommended that effluent limits and monitoring
requirements be placed in the permit for oil and grease. No
toxicity testing or chemicals scans should be required.
It is recommended that a permit be drafted for reissuance
and placed at public notice. If there is no significant
opposition it is recommended that the permit be reissued for a
period of five years.
