BMP Summary
Best management practices (BMP's) are measures developed and implemented to prevent
or minimize stormwater runoff discharges from becoming contaminated with pollutants.
BMP's are broad ranging and may include processes, procedures, managerial controls,
and structural controls. BMP's are selected to prevent contamination by stressing the
importance of stormwater management and employee awareness of potential pollutant
sources. North Carolina's NPDES stormwater permit program requires each facility
covered by the permit to develop and implement appropriate stormwater management
controls. The following stormwater management controls are practiced at this facility.
Other BMP's are included in different sections of the SWPIII but are not limited to: Good
Housekeeping and Preventative Maintenance, Inspections, Sediment and Erosion
Control, and Spill Prevention and Response.
Oil and Grease Separation
Activities or processes at the facility, which use oil and grease, are performed in such a
manner that does not allow exposure to stormwater or stormwater runoff. All waste oil or
waste oily water is collected and transferred to oily water holding tanks for regular
disposal by a licensed waste management contractor.
Vegetative Filter Strips
There are several large grassed and wooded areas on the facility site. These areas serve as
vegetative filter strips and buffers zones around the property. Of particular importance is
the wooded and grassed area on the east side of the property, which borders Silver Creek.
None of the stormwater runoff from the main production areas of the facility discharges
through these vegetative filter strips. Stormwater conveyances throughout the production
areas of the facility discharge runoff without the benefit of vegetative filter strips;
however, sheet flow discharge from non -production border areas does benefit from the
vegetative areas that are maintained.
Infiltration
A large portion of the surface area of the site is paved; therefore, infiltration mostly
occurs on the graveled and grassed areas of the facility. To aid and continue the limited
infiltration that occurs, vegetative areas are maintained.
Stormwater Detention/Retention
There is one area of potential stormwater retention on -site. This was a reclamation area
located on the eastern side of the facility. A large berm was constructed along the eastern
edge of the property bordering Silver Creek to eliminate stormwater runoff from the
reclamation area. Stormwater that may collect in the reclamation area is dissipated either
through infiltration or evaporation.
Management of Runoff
Runoff at the SGL Carbon, LLC facility is managed using a large storm sewer system,
which collects almost all stormwater runoff from the production and manufacturing areas
of the facility. Roof drainage is directed by gutters to exterior downspouts. The site is

graded such that drainage from the areas around buildings and downspouts is directed
away from the buildings, toward the catch basins located throughout the main plant
production areas. Stormwater collected in most all of the catch basins is discharged to
one outfall located south of the facility. The southwestern most area of the facility drains
south to the ditch along the railroad tracks and to the west into a drainage system that
flows south to Silver Creek. Stormwater from two newly discovered drain pipes
discharges into this same ditch system. Stormwater collected in all secondary
containment dikes is visually inspected before being released. Again, all manholes, catch
basins, stormwater drains, inlets, and outfalls are inspected and cleaned out as needed,
with any accumulated sediment and debris being removed.
Vehicle Maintenance, Cleaning, and Washing
All vehicle and equipment maintenance, cleaning, and washing operations occur in the
Maintenance department. Maintenance takes place inside covered garages and washing
takes place in a diked and covered wash bay. The following Best Management Practices
apply to all maintenance, cleaning, and washing of vehicles and equipment:
All parked vehicles are monitored for drips and leaks, with drip pans being placed under
any leaks or drips to collect the fluids for proper disposal or recycling.
Solvent use at the facility is kept to a minimum to reduce the burden of recycling and the
possible generation of hazardous waste. Steam cleaning and pressure washing may be
used instead of solvent parts cleaning. Wastewater generated from cleaning is discharged
to the oily water tank.
Vehicle parts are cleaned without using liquid cleaners whenever possible to reduce
waste.
Small parts and equipment are washed using a vendor supplied system whenever
possible. The vendor then collects, disposes of, and/or recycles the used solvent on a
regular basis.
If possible, non -caustic detergents will be used instead of caustic cleaning agents,
detergent -based or water -based cleaning systems will be used instead of organic solvent
degreasers, and non -chlorinated solvents will be used in place of chlorinated organic
solvents for parts cleaning.
All washing of vehicles or equipment should be performed in the diked and covered wash
bay. Wash water is collected in the oily water holding tank for later disposal by a licensed
waste management contractor. No wash water is discharged to the storm drain system,
stormwater discharge outfall, or sanitary sewer. Vehicle washing should be performed
using biodegradable, phosphate -free detergents when possible and if available. If it is not
feasible to wash the vehicles or equipment in the designated wash bay, then an
appropriate outside area will be assigned for washing. This area should be diked or
bermed to collect the wash water and the wash water pumped to an oily water holding
tank.

Industrial Activity Narrative for 2013 Storm Water Permit Renewal
SGL Carbon, LLC operates a carbon graphite manufacturing facility located at 307
Jamestown Road in Morganton, NC. The facility processes raw materials such as coal
coke and coal tar pitch using extrusion, baking and graphitizing to manufacture specialty
graphite products under SIC code 3624. This facility has operated here for over
seventy years and while the basic process is the same there have been some changes
in industrial activity since our last storm water permit application. These are discussed
below.
Improvements to Storage Practices
1. SGL stores heavy paraffin "extrusion" oil in two above ground tanks. There has
been a significant upgrade to the secondary containment of these tanks including
the addition of a poured, concrete dike around both tanks and associated piping.
2. The vehicle refueling tanks have been replaced with NFPA approved, double -walled
storage tanks that are compliant with SPCC rules. These tanks replace single -
walled tanks, some in earthen berms and contain less fuel than those they replaced.
3. Several storage tanks have been removed from service since the last renewal.
These include a large #2 fuel oil tank, a kerosene tank, an acid storage tank as well
as the gasoline and diesel fuel tanks mentioned in item 2.
4. We have upgraded our accumulation of wastes by purchasing a containment shelter
for our hazardous waste accumulation drum and replacing an oil filter crusher with a
secure collection service that provides containers for the collection.
Raw Materials
The raw materials used in our process are essentially unchanged and include various
cokes, pitches and oils. We have eliminated the use of a hydrochloric and phosphoric
acid mixture that had potential to impact storm water.
Other improvements/ changes to industrial activities
1. Fume collection at our pitch working tanks was upgraded with the addition of heated
collection ducts. This eliminated the need for a tank to collect condensed pitch
fumes which was a potential spill source.
2. The use of portable tanks to collect various small waste streams such as steam
condensate and compressor blow down has been reduced by the addition of
condensate return lines, improved maintenance of equipment and replacement of
outdated air compressors with new.
3. During an internal audit in June, 2013 two previously unidentified storm drain outfalls
were discovered. Both of these drain an area of our rail spurs and exit the property
into a ditch along the railroad to the south of the facility. The area drained is a low
risk area for storm water contamination and any discharge from these lines is
expected to be similar to our 001 outfall and most likely will be "cleaner". These are
identified on the new site drawing.
