SUBJECT: Settleable Solids Limit for Marathon Petroleum Company
NPDES Permit No. NCO046213
Mecklenburg County
The Technical Support Branch has reviewed the letter from Mr.
P.J. Barnes concerning the subject facility. Upon review of their
self -monitoring data for the past year, it is our recommendation
that the settleable solids limit of 0.1 ml/l be removed from their
NPDES permit and replaced with a Total Suspended Solids (TSS) limit
of 30 mg/l. If Marathon Petroleum does not agree with this revi-
sion, it is recommended that they pursue a SOC through the Moores-
ville Regional Office.
Please contact me if there are additional questions concerning
this matter.

NPDES Permit - NCO046213
SUBJECT: NOTICE OF VIOLATION - EFFLUENT LIMITATIONS, BY
BRENDA SMITH, NCDEHNR, REGIONAL SUPERVISOR,
MOORSEVILLE, NC, DATED AUGUST 6, 1990
Dear Mr. Safrit:
I
This letter is in response to the NOV we received from Ms. Brenda Smith of
the Moorseville regional office on August 6, requesting remedial action be
taken to correct exceedences for settleable solids (0.1 ml/l limitation)
for the above -referenced facility during April and May 1990. *
We have reviewed our sampling procedures, the control laboratory
procedures, and the circumstances surrounding excursions of the settleable
solids levels, with respect to our NPDES permit limitation, and conclude
that the procedures are adequate and are being performed correctly. We
have also reviewed the frequency of wastewater discharges to the pond
basin over the past year and note that they are not a factor as evidenced
by the frequency, which has been very low, and analysis of the samples
taken over that period.
Our analysis indicates that the problem is exacerbated by rainfall. The
pond outfall (001) is sampled whenever their is a discharge from the
pond. These discharges have been noted to occur after a heavy rainfall.
* Based on limitation shown in NPDES permit, dated September 1, 1989.

The run-off from the surrounding area washes considerable a�ounts of
solids into the basin. As the level rises, there is insufficient
residence time for the solids to "settle" out before discharge occurs.
We plan to further investigate and study methods to improve our ability to _�--j
comply with the NPDES settleable solids limitation. However, in the
meantime, we request that your office review the present NPDES settleable
solids limitation for applicability given the conditions that prevail at
our terminal.
If the settleable solids limit cannot be changed, please advise if an . C_
interim, less stringent limit may be obtained. If that is not possible,
please advise me on what other vehicle might be available to Marathon
while we study the situation more fully.
If you have any questions, please contact N. A. Andon at extension 2678.
Future correspondence on this matter should be directed to G. D. Sheely,
Manager, Environmental & Regulatory Compliance.
