Permitting section
On May 24, 2017, Min Xiao of this office met with you and Michael Bennett to perform a
Compliance Evaluation Inspection on the stormwater management system at Motiva's Greensboro
Terminal. The facility was found to be compliant with the NPDES discharge permit. The
inspection findings are detailed below and an inspection checklist is attached.
I. Permit
The permit became effective January 1, 2017, and will expire at midnight on August 31, 2021. A
current permit is kept on-site.
II. Self-Monitorint; Prot,,ram
Monthly discharge monitoring reports (DMRs) were reviewed from March 2016 to February 2017.
The facility was found to be compliant with the NPDES effluent limits for the above period. In
regards to the permit monitoring requirements, it was noted that all sampling was performed per
the frequencies specified in the permit. Only flow is measured on-site, other parameters are tested
byR&ALabs.
III. Facilitv Site Review
The Motiva facilty has the following stormwater structures:
• fueling island that drains to a 11,000 -gallon concrete separation pit with a sump pump.
• the pit water is transferred to an 8,000 -gallon PCW (petroleum contact water) AST with a
hydrocarbon detector. Tank contents typically released into the diked area. It can be hauled
off if contaminated.
• diked secondary containment berm surrounding the hydrocarbon fuel and ethanol ASTs.
• settling pond with locked effluent release valve and flow totalizer.

IV. Flow Measurement
The permit requires episodic flow monitoring. Flow is measured using a totalizing meter on the
effluent pipe. The meter is calibrated once a year. The discharge is controlled manually by a locked
release valve.
V. Records/Reports
A review of the facility files showed that all records were being maintained according to the permit.
A comparison of the January 2017 DMR with the corresponding certified laboratory data sheets
from R&A Labs showed that all the results were properly transcribed onto the self-monitoring
report. The retention pond draining report logs were also reviewed which document the effluent
release dates and totalizer readings. Flow, TSS, Oil -Grease, and Turbidity values were transcribed
correctly. The units of Benzene, Ethylben, MTBE, Napthale, TR Phen, Toluene, and Xylene are
mg/L, however, the units of these parameters on the DMR are ug/L. A transformation is needed
before transcribing the data from lab sheets to the DMR. Please correct this in the following DMRs.
VI. Effluent/ReceivhW Waters
The system discharges to a rip rap lined ditch just outside of the perimeter fence. The effluent
eventually reaches a tributary of Long Branch, class "WS -IV *" waters of the Cape Fear River
Basin. No effluent was being discharged on the day of the inspection.
Should you have any questions concerning this report, please contact Min Xiao or me at (336)
776-9800.

hydrocarbon detector. Tank contents typicglly released into the diked area. It can be hauled
off if contaminated.
-diked secondary containment berm surroun4LM the hydrocarbon fuel and ethanol ASTs.
-setti_ing pond with locked effluent release valve -and flow totalizer.
The units of Benzene Eth Iben MTBE Na thale TR Phen Toluene and Xylene are mg/L.
however, the units of these parameters on the DMR are ug/L. A transformation is needed
