Subject: Compliance Evaluation Inspection
Magellan Selma Terminal
NPDES Permit No. NC0052311
Johnston County

Dear Mr. Maguire:

On July 7, 2021, Jason Robinson of the NC Division of Water Resources’ Raleigh Regional Office (RRO)
conducted a compliance evaluation inspection of the subject facility. The assistance provided by Mr. Jimmie
Williamson and Mr. Larry Edwards was appreciated. Below is a list of findings developed from the inspection:

1. The most recent permit became effective on August 1, 2018 and expires on March 31, 2023.

2. The facility consists of a loading rack area, an ethanol and butane offloading skid with 4 offloading
ports and a 100-gallon sump-pump tank, a secondary earthen berm containment area surrounding
above ground storage tanks (AST’s) a lockable gate valve at the southeastern side of the secondary
containment area, two small retention ponds in series joined together with a submerged pipe, and a
gate valve at the discharge point. The facility does not employ an oil/water separator in the process
wastewater flow.

3. Any spillage in the loading rack area drains to the sump tank and is currently pumped to AST #43. Fuel
that is captured is re-blinded into the other fuels. Eastern Environmental or Zebra Enviro removes and
further reclaims product from the petroleum contact water that is drawn off the tank.

4. Water that is collected in the secondary containment area may evaporate and infiltrate. Excess water
may be released into the retention ponds in series via a gate valve. The gate valve is kept closed and
locked except when discharging water from the containment area, as the retention ponds are spring-
fed and will sometimes back-up into the secondary containment area. Other stormwater collected on
the south side of the pond and the roadside is also routed to the ponds. Water is discharged from the
ponds into a ditch behind the pond with a second gate valve that is usually kept open to allow spring
water to continually drain from the ponds. Samples are taken in the pond at the discharge pipe, as the
discharge point in the ditch is typically underwater. Flows are estimated using the rational method. A
table is used that provided the volume based on amount of rainfall, as averaged by two rain gauges
on-site.




  
 


5. Standing water that was observed in the tank containment area and in retention ponds in series
appeared to be clear with no oily sheen at the time of the inspection.

6. Lab results, chain-of-custody forms, and DMRs were complete and current, kept in good order and
ready for review. Pace Analytical is used to analyze the effluent. September 2020 and February 2021
DMRs and lab bench sheets were compared and no discrepancies were found. The facility keeps an
operators log with dates and depths of discharges.

This facility was found to be compliant with NPDES permit conditions as a result of this inspection. If you have
any questions regarding the attached reports or any of the findings, please contact Jason Robinson via email at
[e-mail]).

Sincerely,

Vanessa Manuel, Assistant Regional Supervisor
