Dear Ms. Cloutier:
This letter is in response to your report providing follow-up information on two MTBE reduction plans for the above referenced
facilities.
Information provided in your report indicates that MTBE has been detected during one sampling event at Charlotte South
Terminal (NPDES Permit #NC0046892). According to your letter, this exceedence could be attributed to a power failure as a result
of an ice storm. Due to the low likelihood of such an event being repeated on a regular basis, DWQ shall not require Plan of Action
for MTBE reduction at this time.
Monitoring at the Charlotte North Terminal (NPDES Permit #NC0022187) has shown the presence of MTBE in Outfall 001 on a
more frequent basis. Therefore, DWQ shall require a Plan of Action for MTBE reduction for the Charlotte North Terminal.
Such a plan might include installation of a filtration device at the point of discharge and/or elimination of the source of MTBE.
Should you have any questions about these decisions or MTBE policy, please feel free to contact Sergei Chernikov at (919) 733-
5083, extension 594.
Sincerely,
David A. Goodrich

Per Permit Condition A.(4) of NPDES Permit NC0046892, Motiva Enterprises LLC — Charlotte South
Terminal is providing follow-up information on the status of the MTBE reduction plan for the facility.
Monthly monitoring of MTBE at Outfalls 001 and 002 has been required since the effective date of the
permit on September 1, 2001.
Attachment A indicates that for the period of September 2001 through July 2003 MTBE has been
detected in Outfall 001during only one sampling event. This sampling event in December 2002, which
indicated a MTBE result of 74 ug/1, can be attributed to the ice storm that shut down the facility power
supply. At that time the oil/water sump pump was not operating correctly allowing some hydrocarbon
contact water to exit the sump to the tank dike area. There has been no MTBE detected in Outfall 002
during the reporting period of September 2001 through July 2003.
Per the permit requirements, Motiva will continue MTBE sampling on Outfall 001 and 002 until a period
of 8 to 10 sampling events have been gathered which show non -detection levels in both outfalls. At that
time a minor permit modification request will be submitted to the NCDENR to reduce the MTBE
monitoring at the facility.
If you have questions pertaining to the information presented in this report, please contact me at 919-387-
5764.
Sincerely,
Motiva Enterprises LLC
