Site Inspection Deficiency Comments
Stormwater system (catch basins,
No
Stormwater flows through the site via sheet flow to a concrete
inlets, outfalls, etc.)
retention pond where stormwater is contained until it is
manually discharged to outfall #001 via a gate valve.
Erosion issues
Recommendation
Erosion was observed at the discharge point of outfall #001.
CMSWS recommends stabilizing the area with an energy
dissipator (ie. riprap) or another means of stabilization to
prevent ongoing erosion.
Structural stormwater BMPs
No
The facility has one concrete retention pond that collects flow
from the facility grounds. The basin outlet is controlled with a
gate valve that remains closed, providing a containment point
for any potential spills occurring on site. Per facility
personnel, the capacity of the basin is 22,500 cubic feet.
Illicit discharges/connections
No
No illicit discharges or connections were observed during the
inspection.
Aboveground storage tank(s) - list
No
The facility has four 25,000 -gallon tanks and three

INSPECTION DETAILS
Site Inspection Deficiency Comments
Outdoor material storage area(s)
Recommendation
At the time of inspection, a large tank previously used for
chemical processing was observed to be stored outdoors with
the lid slightly askew, allowing accumulation of stormwater.
All valves were closed and no discharge was observed around
the vessel; however, CMSWS recommends the tank be
covered to prevent stormwater accumulation and potential
unintended discharge. Additionally, an empty 55 -gallon drum
of unknown previous contents was stored outdoors with the
lid not properly placed.
Outdoor processing area(s)
No
Loading/unloading area(s)
No
Vehicle/equipment area(s) - fueling,
No
The facility does not conduct vehicle fueling, washing, or
washing, storage, etc.
maintenance on site.
Oil/water separator and/or
No
As a part of primary facility operations, certain types of
pretreatment
chemicals received by the facility are processed using an air
sparger, thermal treatment, and plate/press treatment. Upon
final treatment, the waste stream is then discharged to the
sanitary sewer via two 'outfalls" that are monitored by the
facility and inspected periodically by Charlotte Water
(formerly Charlotte Mecklenburg Utilities).
Waste storage/disposal area -
No
dumpsters, scrap metal bins, etc.
Food service area(s)
N/A
Indoor material storage area(s)
No
The facility stores 55 -gallon drums, totes, and other
containers of various caustics, corrosives, flammables, and
other chemicals. The chemical storage areas were observed
to be well kept and organized based on type / reactive nature.
Dikes were located at each point of ingress/egress to prevent
a potential spill from discharging outdoors, and
chemical -specific storage areas were also divided by dikes.
Indoor processing area(s)
No
Indoor processing areas consist of components related to
waste processing/treatment, including an air sparging unit,
plate press filter unit, and associated tanks.
Floor drains
No
Grated trench drains / floor drains were observed in several
areas of the facility. Per the facility manager, these drains
are "dead sumps" and any accumulated product is vacuumed
out and placed into a tank for on-site treatment.
Spill response equipment
No
Spill response equipment was observed in a shed at the rear
of the facility. The facility has contracted with Shamrock
Environmental to provide emergency response services in the
event of a significant spill.
