Proiect Notes
Overview.
• This is a permit renewal for a railroad fueling/maintenance operation (SIC 4011) in Davidson County. Per
application, runoff and drainage from diesel fueling area, locomotive service area (5 acres), AST containment
area, and buildings is routed to the 0.317 MGD industrial WWTP. The 1993 staff report mentions boron -treated
cooling water used in the locomotives is also discharged. Daily average process wastewater discharge is 0.069
MGD.
• In addition, stormwater runoff from the yard as a whole is routed to ten stormwater outfalls (001-010).
DMR Data
• Toxicity test results have improved since the last permit round. Facility passed the quarterly chronic tox test in
1997 and 1998, with one failure in 1999.
• DMR data for past year (10/98- 9/99) is compliant, except for 1 monthly avg violation of phenol (9/99) and one
monthly avg violation for TSS (10/98). Quarterly nutrient data for past year ranged from 2.6-6.5 mg/I for TN,
and 0.2 to 0.6 mg/I for TP. Monthly avg flow ranged from 0.015 - 0.150 MGD.
Permit Issues.
• I changed facility class from III to II, with subsequent change in monitoring frequencies for some parameters,
based on new rating system. WSRO- Please verify that Class II is correct facility rating.
• I removed instream monitoring for conductivity, since instream data shows no increase whatsoever over past
year. We generally use this parameter mostly for dischargers of inorganic contaminants. WSRO- comments?
N • I removed instream monitoring for teutpeiatu am a ny-decrease-at-the-
1 as ewa eadingv1 C7.t.essive-nuh7ent
I'Z
nts?
I retained instream monitoring for turbidity, since high turbidity levels have been a concern in High Rock Lake.
I left the receiving stream as High Rock Lake for Outfall 011. File notes were mixed as to whether South Potts
Creek (Class C) or High Rock Lake (Class WS-V) should be the receiving stream for this outfall. If we keep the
receiving stream as High Rock Lake, the permit needs a) review by DEH; 2) phenol limits due to water supply
designation; and 3) turbidity limit of 25 NTU (lake) rather than 50 NTU (stream). WSRO- can you shed any
light on this? Both High Rock Lake and South Potts Creek are not listed on the 1998 303(d) list.
Stormwater Unit.
• I had Bill Mills of Stormwater Unit review permit. Bill indicated there was no stormwater general permit to
cover all current discharges (stormwater +process), therefore NPDES will need to renew as individual permit
again. Bill provided new stormwater language from NCG080000, which 1 incorporated into permit renewal as
applicable.
WSRO Region.
• Last staff report prepared 4/26/93.

Secondary Containment Schedule. A schedule to provide secondary containment for bulk storage
of liquid materials, storage of Section 313 of Title III of the Superfund Amendments and
Reauthorization Act (SARA) water priority chemicals, or storage of hazardous substances to
prevent leaks and spills from contaminating stormwater runoff. If the secondary containment
devices are connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices [which shall be secured with a
locking mechanism] and any stormwater that accumulates in the containment area shall be at a
minimum visually observed for color, foam, outfall staining, visible sheens and dry weather flow,
prior to release of the accumulated stormwater. Accumulated stormwater shall be released if found
to be uncontaminated by the material stored within the containment area. Records documenting
the individual making the observation, the description of the accumulated stormwater and the date
and time of the release shall be kept for a period of five years.
BMP Summary. A narrative description shall be provided of Best Management Practices (BMPs)
to be considered such as, but not limited to, oil and grease separation, debris control, vegetative
filter strips, infiltration and stormwater detention or retention, where necessary. The need for
structural BMPs shall be based on the assessment of potential of sources to contribute significant
quantities of pollutants to stormwater discharges and data collected through monitoring of
stormwater discharges.
Locomotive Sanding Areas (applicable to Rail Transportation only). The plan must describe
measures that prevent or minimize contamination of the stormwater runoff from areas used for
locomotive sanding. The facility shall consider covering sanding areas, minimizing stormwater
runonlrunoff, appropriate sediment removal practices to minimize the offsite transport of sanding
material by stormwater, or other equivalent measures.
Vehicle and Equipment Cleaning Areas. The plan must describe measures that prevent or
minimize contamination of the stormwater runoff from all areas used for vehicle and equipment
cleaning. The facility shall consider performing all cleaning operations indoors, covering the
cleaning operation, ensuring that all washwater drain to the sanitary sewer system (i.e., not the
stormwater drainage system), collecting the stormwater runoff from the cleaning area and
providing treatment or recycling, or other equivalent measures. If sanitary sewer is not available to
the facility and cleaning operations take place outdoors, the cleaning operations shall take place on
grassed or graveled areas to prevent point source discharges of the washwater into the storm drains
or surface waters. Where cleaning operations can not be performed as described above and when
operations are performed in the vicinity of a storm drainage collection system, the drain is to be
covered with a portable drain cover during clean activities. Any excess ponded water shall be
removed and properly handled by pump to a sanitary sewer system prior to removing the drain
cover. Detergents used outdoors shall be biodegradable and the p-I adjusted to be in the range of 6
to 9 standard units.
Remote Fueling Operations. If remote fueling (or other vehicle maintenance activities ) are
conducted at off site locations but coordinated from the permitted facility, the plan shall include a
component that describes the stormwater management practices and BMPs used to prevent and/or
minimize the contamination of stormwater from such activities.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP) shall incorporate an
assessment of potential pollutant sources based on a materials inventory of the facility. Facility personnel
(or team) responsible for implementing the SPRP shall be identified. A responsible person shall be on -site
at all times during facility operations that have the potential to contaminate stormwater runoff through spills
or exposure of materials associated with the facility operations. The SPRP must be site stormwater specific.
Therefore, a SPCC plan may be a component of the SPRP, but may not be sufficient to completely address
