7. Size (land available for expansion and upgrading). Ample
land area available for expansion/upgrading, if necessary.
Br Topography (relationship to flood plain included). Gently
rolling with 3- slpoes. "Wastewater treatment facilities
are not in a flood plain.
9. Location of Nearest Dwelling: None within 500 feet of the
treatment facility.

10. Receiving Stream or Affected Surface Waters: Unnamed
tributary to Lung Creek Crooked Creek
a. Classification: C
b. River Basin and Subbasin No.: Catawba and 03-08 34
C. Describe receiving stream features and pertinent
downstream uses: The receiving strum is a dry ditch
about 51' wide and 12" deep. The''ditch may be tributary
to Long Creek. Some flaw was observed on the day; of
the inspection. However, the flow may be attributed to
recent rain events and subsequent runoff from the tank
farm area. Downstream users're unknown.
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
1. Type of Wastewater: 0% Domestic'
00 Industrial
a. Volume of Wastewater: N/A MGD* (resign Capacity)
* intermittent discharge, dependent on rainfall
b. Types and quantities of industrial wastewater: The
wastewater is generated from the fuel loading area and
from the dyed tank farm area. No other wastewater
enters the wastewater treatment system. Currently,
the oil storage facility is not in use. Therefore, no
industrial wastewater is generated from this facility.
c• Prevalent toxic constituents in wastewater: N/A
d. Pretreatment Program (POTWs only): N/A
n development approved
should be required not needed
. Production Rates (industrial discharges only) in pounds per
day: N/A
a. Highest month in past 12 months:lbs/day
b. Highest year in the past 5 years: lb/day
. Description of Industrial Process (for industries only) and.
Applicable CFR Part and. Subpart: Petroleum storage and
distribution (gasoline, Fuel oil and Kerosene).
4. Type of Treatment (specify whether proposed or existing):
The existing facility consists of an oil/water separator.
5. Sludge handling and Disposal Scheme. Oil is removed by a
waste oil contractor.

* Four grab samples shall be taken for each discharge. The four grab samples shall be collected
at equal intervals over any fourth -five minute; period of discharge.
* The daily, maximum for each discharge shall be determined as the arithmetic average of the four
grab sample concentrations. This arithmetic average and the flawfor each discharge shall be

excluded it if is the only sample taken by the permittee during a
calendar month. Such a declaration must be included in writing
with the next Discharge Monitoring Report submitted in accordance
with Part T., C., 2. of this permit, and must include the results'
of the analysis of the excluded sample, and a written explanation
for the exclusion of that sample. if any sample is so excluded,
the "daily average" concentration shalt be the arithmetic average;
of the analyses of the remaining non -excluded samples.
Other petroluem company officials have contended that, while the
discharges from most of their marketing `and :bulk terminals are
capable of meeting this. "daily maximum" limitation as stated
above, certain of ;their facilities cannot be so equipped to meet
this 'limitation as stated above. If the permittee can present
sufficient evidence to demonstrate that this facility cannot be so
equipped, the Stave will modify this limitation to the extent
needed (in no case to exceed 100.0 mg/1) to assure reasonable
complicance with the "daily maximum" limitation.
1. It is recognized that influent quality changes, equipment
malfunction, or other circumstances may sometimes result in
effluent concentrations exceeding the permit limitations despite
the exercise of appropriate care and maintenance measures, and
corrective measures by the permittee. The permittee may; come
forward to demonstrate to the Stag that such circumstances exist
in any case where effluent concentrations exceed those set forth in
this 'permit. The State will consider such information in
determining appropriate enforcement measures, if any, to be taken.
J. A calendar day is defined as any consecutive 24`,hour period.
K. The "daily maximum" concentration is defined as the arithmetic
average of one or; more representative grab samples taken during any
calendar day. Should effluent sampling be clone on more than one
calendar day :during the month, the arithmetic average indicating
the Largest "daily maximum" concentration shall be reported on the
Discharge Monitoring Report Form
L. Collection of representative samples shall be required during
periods of di` hages Should there be no discharge during normal
working hours', the permittee shall report "no discharge" for that
reporting period.
M. The reported flow shall be the arithmetic average of the total
volume discharged on each of the sampling days during the reporting
period. Flow may be calculated utilizing a flow recorder, rain
gauge, or any other simliar device.
N. In connection with submission of records and reports required under
this permit, the permittee shall not be deemed to have waived such
privilege against self-incrimination as may be offered under or by
the Fifth Amendment of the United States' Constitution.
