Dear Ms. McCoy:
Duke Energy 526 South
Church Street Charlotte,
NC 28202
Mailing Address:
Mail Code EC13K1 P.O. Box 1006
Charlotte, NC 28201-1006
NCDEQ staff have recently requested that Duke Energy Carolinas, LLC (Duke Energy) submit a permit
renewal application for the Riverbend NPDES Stormwater Permit number NCS000549, to maintain the
permit while the agency finishes review of the permit rescission request and no exposure certification
submitted for the site on October 21, 2019 and October 7, 2019 respectively.
As indicated in our previous submittals, there is no industrial activity at the site that would require
continuing NPDES stormwater permit coverage. Steam electric energy generation and ash excavation and
transport have been completed and have permanently ceased at the site. Duke Energy requests both the
No Exposure certification for the Lark maintenance facility and Rescission or expiration of the subject
permit be completed as previously requested.
In response to the agency's request however, Duke Energy attaches a:
1. Renewal Application Form,
2. SPPP Certification Form,
3. Map of site drainage areas,
4. Analytical and Visual Summary Spreadsheets and
5. Drainage area Descriptions.
If you have questions or need additional information, please contact Brad Loveland at
[phone] or [e-mail].

This drainage area includes runoff from the 44 kV switchyard, lower 230 kV
and Description
switchyard, and a portion of the main switchyard; these areas cover 3.5 acres,
including half an acre of yard and parking. To the south of the main switchyard,
there are approximately 4.3 acres of lawn area.
The railroad embankment along the eastern basin boundary is sloped at a ratio
of 1.5 horizontal to 1 vertical (1.5H: 1V). The embankment and railways cover
approximately 2.3 acres. About one mile of railways and one-third mile of
paved roadways pass through the area. Due to the removal / closure of the ash
basin, ash hauling is no longer occurring onsite.
Approximately 35 percent of this drainage basin is paved. All runoff from this
drainage basin is processed through the 10,000 gallon oil separator tank #2.
There is a vehicle rinse area within this basin, but the effluent is not discharged
through this outfall because it is routed to the ash basin through the septic
system.
Effective July 7, 2017 a new Erosion and Sediment Control Plan (GASTO 2017-
016) was approved for the 100kV Switchyard Demolition and Stormline
Installation (Phase 6). This new E&SC Plan necessitated replacement of the
existing SWO02 stormwater discharge pipe, which occurred on 9/18/17 by
Earnhardt Grading. The original discharge has been abandoned in place.
Significant
Oil: The 44 kV switchyard contains a total volume of 5,000
Materials/Potential
gallons of mineral oil. The main switchyard is only
Pollutants
partially located within this drainage area. Transformer
7A and its 7,500 gallons of mineral oil are located in this
drainage area. Some switchgear equipment has
containment pits beneath them. In addition, the diesel
fuel storage tank (280 gallons) and unloading
operations are located here on the east side of the
powerhouse.

the Lark Maintenance Facility. Approximately ten acres of lawn area border
the plant access road. Drainage from the three acre, upper 230 kV
switchyard is discharged into a concrete ditch which leads to this outfall.
About 900 feet of paved access road and 800 feet of railways border this
area. Approximately 5 percent of this drainage basin is paved.

collection tank collects drainage from the two station service

Runoff from the upper 230 kV switchyard is discharged into a
concrete ditch running along the north side of the yard. The ditch
passes under the plant access road through a 36 inch diameter
CMP. The west end of the CMP has a swing gate which would be
closed to help contain oil spillage from the switchyard.

Industrial Activities
The drainage area for the proposed stormwater outfall SW018 covers a total
and Description
area of 8.8 acres. The majority of stormwater is generated due to runoff from
the substation pad. This stormwater will be collected using a network of
catch basins and storm drains and subsequently conveyed to a detention
basin and then discharged through the new outfall. The detention basin will
also receive sheet flow from a grassed area around the substation pad. The
area where the substation pad is built used to be the coal stock pile area
when the plant was under operation. The substation pad will be covered with
6 inches of #57 stone and contain various electrical equipment including
transformers, circuit breakers, and metering devices. The substation will be
built in two phases. Phase One will be the construction of a 100kV switchyard
and Phase Two will be the 44kV transformation yard. The transformers
containing mineral oil will be located in the 44kV yard. Drainage will be
routed to a 10,000 gallon oil water separator (proposed for construction) prior
to discharge into the detention basin.
Significant
Mineral Oil: There will be multiple oil -filled transformers in
Materials/Potential
the new 44kV substation which will be installed
Pollutants
during Phase 2 of the Substation Construction.
The transformers contain approximately 6000-
8000 gallons of oil. The oil water separator will
be sized to accommodate the largest volume
and installed prior to transformer delivery. The
separator will tie into the storm drainage within
the switchyard and be routed to the detention
basin.
BMP Summary
Oil bearing equipment switchyards
• Level grades and gravel surfaces are constructed to retard flows and
limit the spread of spills.
• Stormwater runoff is collected in perimeter ditches and routed around
switchyard.
