Subject: Compliance Evaluation Inspection
Zenith Energy - Selma
NPDES Permit No. NC0027227
Johnston County

Dear Mr. Caldwell:

On July 1, 2021 Jason Robinson of the Raleigh Regional Office (RRO) conducted a compliance evaluation
inspection of the subject facility located at 29999 W Oak Street, Selma. The assistance provided by Mr. Ben
Smith, terminal manager was appreciated. Below is a list of findings developed from the inspection:

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

2. The facility consists of two oil/water separators, a product holding tanks, and a 12,000-gallon
Petroleum Contact Water (PCW) tank. Water that is collected at the covered loading rack area flows
through two oil/water separators. Any oil captured from the oil/water separators flows to the
product holding tank behind the main office, which is regularly pumped and treated off site by
Hepaco. The water captured from the oil/water separator flows to the PCW tank which is
underground in the tank secondary containment area. The PCW tank is also pumped and treated
offsite. Several pumps are located in the tanks secondary containment area, but are separated by a
berm. A pump is present to pump any water that collects in the pump area to the secondary
containment area.

3. The secondary containment area is slightly sloped towards a discharge pipe in the southwest corner.
When enough water is standing, a raised pipe inside the secondary containment area is manually
lowered via a hand-crank, and the water travels through the pipe and is discharged on the other side
of the fence into a ditch in a wooded area. Water in the containment area often infiltrates or
evaporates and eliminates the need for frequent discharges. The hand-crank is tested monthly.
