This facility shall meet the requirements of Senate Bill 729 (Coal Ash Management Act). This permit
may be reopened to include new requirements imposed by Senate Bill 729.
A. (27.) STORMWATER POLLUTION PREVENTION PLAN
The permittee shall develop and implement a Stormwater Pollution Prevention Plan (SPPP). The
SPPP shall be maintained on site unless exempted from this requirement by the Division. The SPPP
is public information. The SPPP should also specifically and separately address deconstruction,
demolition, coal, and/or coal ash hauling or disposal activities The SPPP shall include, at a
minimum, the following items:
1. Site Overview. The Site Overview shall provide a description of the physical facility and the
potential pollutant sources that may be expected to contribute to contamination of stormwater
discharges. The Site Overview shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted equivalent map),
showing the facility's location in relation to transportation routes and surface waters; the
name of the receiving waters to which the stormwater outfalls discharge, or if the discharge
is to a municipal separate storm sewer system, the name of the municipality and the
ultimate receiving waters; and accurate latitude and longitude of the points of stormwater
discharge associated with industrial activity The general location map (or alternatively the
site map) shall identify whether any receiving waters are impaired (on the state's 303(d) list
of impaired waters) or if the site is located in a watershed for which a TMDL has been
established, and what the parameters of concern are.
(b) A narrative description of storage practices, loading and unloading activities, outdoor
process areas, dust or particulate generating or control processes, and waste disposal
practices. A narrative description of the potential pollutants that could be expected to be
present in the stormwater discharge from each outfall. The narrative should also reference
deconstruction, demolition, coal. and/or coal ash hauling or disposal activities where
applicable.
(c) A site map drawn at a scale sufficient to clearly depict: the site property boundary; the
stormwater discharge outfalls; all on-site and adjacent surface waters and wetlands;
industrial activity areas (including storage of materials, disposal areas, process areas,
loading and unloading areas, and haul roads); site topography and finished grade; all
drainage features and structures; drainage area boundaries and total contributing area for
each outfall; direction of flow in each drainage area; industrial activities occurring in each
drainage area; buildings; stormwater Best Management Practices (BMPs); and impervious
surfaces. The site map must indicate the percentage of each drainage area that is
impervious, and the site map must include a graphic scale indication and north arrow.
(d) A list of significant spills or leaks of pollutants during the previous three (3) years and any
corrective actions taken to mitigate spill impacts.
Page 20 of 24
Permit NC0001422
(e) Certification that the stormwater outfalls have been evaluated for the presence of non-
stormwater discharges. The permittee shall submit the first certification no later than
90 days after the effective date of this permit to the Stormwater Permitting Program
Central Office and shall re -certify annually that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. For any non-stormwater
discharge identified, the permittee shall indicate how that discharge is permitted or
otherwise authorized. The certification statement will be signed in accordance with the
requirements found in Part II, Standard Conditions, Section B, Paragraph 11.
2. Stormwater Management Strategy. The Stormwater Management Strategy shall contain a
narrative description of the materials management practices employed which control or
minimize the stormwater exposure of significant materials, including structural and
nonstructural measures. This strategy should also address deconstruction, demolition, coal,
and/or coal ash hauling or disposal activities where applicable. The Stormwater Management
Strategy, at a minimum, shall incorporate the following:
(a) Feasibility Study. A review of the technical and economic feasibility of changing the
methods of operations and/or storage practices to eliminate or reduce exposure of materials
and processes to rainfall and run-on flows. Wherever practical, the permittee shall prevent
exposure of all storage areas, material handling operations, and manufacturing or fueling
operations. In areas where elimination of exposure is not practical, this review shall
document the feasibility of diverting the stormwater run-on away from areas of potential
contamination.
(b) Secondary Containment Requirements and Records. Secondary containment is required
for: bulk storage of liquid materials; storage in any amount of Section 313 of Title III of the
Superfund Amendments and Reauthorization Act (SARA) water priority chemicals; and
storage in any amount of hazardous substances, in order to prevent leaks and spills from
contaminating stormwater runoff. A table or summary of all such tanks and stored
materials and their associated secondary containment areas shall be maintained. If the
secondary containment devices are connected to stormwater conveyance systems, the
connection shall be controlled by manually activated valves or other similar devices (which
shall be secured closed with a locking mechanism). Any stormwater that accumulates in
the containment area shall be 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 any material. 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 (5) years. For facilities subject
to a federal oil Spill Prevention, Control, and Countermeasure Plan (SPCC), any portion of
the SPCC Plan fully compliant with the requirements of this permit may be used to
demonstrate compliance with this permit.
In addition to secondary containment for tankage, the permittee shall provide drip pans or
other similar protection measures for truck or rail car liquid loading and unloading stations.
(c) BMP Summary. A listing of site structural and non-structural Best Management Practices
(BMPs) shall be provided. The installation and implementation of BMPs shall be based on
the assessment of the potential for sources to contribute significant quantities of pollutants
to stormwater discharges and on data collected through monitoring of stormwater
discharges. The BMP Summary shall include a written record of the specific rationale for
installation and implementation of the selected site BMPs. The BMP Summary should also
address deconstruction, demolition, coal, and/or coal ash hauling or disposal activities
where applicable. The permittee shall refer to the BMPs described in EPA's Multi -Sector
Permit (MSGP) and Industrial Stormwater Fact Sheet for Steam Electric Power Generating
Facilities (EPA -833-F-06-030) for guidance on BMPs that may be appropriate for this site.
The BMP Summary shall be reviewed and updated annually.
Page 21 of 24
Permit NC0001422
3. Spill Prevention and Response Procedures. The Spill Prevention and Response Procedures
(SPRP) shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel responsible for implementing the SPRP shall be
identified in a written list incorporated into the SPRP and signed and dated by each individual
acknowledging their responsibilities for the plan. A responsible person shall be on-site at all
times during facility operations that have increased potential to contaminate stormwater runoff
through spills or exposure of materials associated with the facility operations. The SPRP must
be site stormwater specific. Therefore, an oil Spill Prevention Control and Countermeasure plan
(SPCC) may be a component of the SPRP, but may not be sufficient to completely address the
stormwater aspects of the SPRP. The common elements of the SPCC with the SPRP may be
incorporated by reference into the SPRP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative maintenance
and good housekeeping program shall be developed and implemented. The program shall
address all stormwater control systems (if applicable), stormwater discharge outfalls, all on-site
and adjacent surface waters and wetlands, industrial activity areas (including material storage
areas, material handling areas, disposal areas, process areas, loading and unloading areas, and
haul roads), all drainage features and structures, and existing structural BMPs.
The program shall establish schedules of inspections, maintenance, and housekeeping activities
of stormwater control systems, as well as facility equipment, facility areas, and facility systems
that present a potential for stormwater exposure or stormwater pollution where not already
addressed under another element of the SPPP. Inspection of material handling areas and
regular cleaning schedules of these areas shall be incorporated into the program. Compliance
with the established schedules for inspections, maintenance, and housekeeping shall be
recorded and maintained in the SPPP. The program should also address deconstruction,
demolition, coal, and/or coal ash hauling or disposal activities where applicable. The Good
Housekeeping Program shall also include, but not be limited to, BMPs to accomplish the
following:
(a) Minimize contamination of stormwater runoff from oil-bearing equipment in
switchyard areas;
(b) Minimize contamination of stormwater runoff from delivery vehicles and rail cars
arriving and departing the plant site;
(c) Inspect all residue -hauling vehicles for proper covering over the load, adequate gate -
sealing, and overall integrity of the container body. Repair vehicles as necessary;
and
(d) Reduce or control the tracking of ash and residue from ash loading and storage
areas;
5 Facility Inspections. Inspections of the facility (including tanks, pipes, and equipment) and all
stormwater systems shall occur as part of the Preventative Maintenance and Good
Housekeeping Program at a minimum on a semi-annual schedule, once during the first half of
the year (January to June), and once during the second half (July to December), with at least 60
days separating inspection dates (unless performed more frequently than semi-annually).
6. Employee Training. Training programs shall be developed and training provided at a
minimum on an annual basis for facility personnel with responsibilities for: spill response and
cleanup, preventative maintenance activities, and for any of the facility's operations that have
the potential to contaminate stormwater runoff. The facility personnel responsible for
implementing the training shall be identified, and their annual training shall be documented by
the signature of each employee trained.
7. Responsible Party. The SPPP shall identify a specific position or positions responsible for the
overall coordination, development, implementation, and revision of the SPPP. Responsibilities
for all components of the SPPP shall be documented and position assignments provided.
Page 22 of 24
Permit NC0001422
8. SPPP Amendment and Annual Update. The permittee shall amend the SPPP whenever there is
a change in design, construction, operation, site drainage, maintenance, or configuration of the
physical features which may have a significant effect on the potential for the discharge of
pollutants to surface waters. All aspects of the SPPP shall be reviewed and updated on an
annual basis. The annual update shall include:
(a) an updated list of significant spills or leaks of pollutants for the previous three (3)
years, or the notation that no spills have occurred (element of the Site Overview);
(b) a written re -certification that the stormwater outfalls have been evaluated for the
presence of non-stormwater discharges (element of the Site Overview);
(c) a documented re-evaluation of the effectiveness of the on-site stormwater BMPs (BMP
Summary element of the Stormwater Management Strategy).
(d) a review and comparison of stormwater sample analytical data to any applicable
limits or benchmark values (if applicable) over the past year.
If the Director notifies the permittee that the SPPP does not meet one or more of the minimum
requirements of the permit, the permittee shall have 30 days to respond. Within 30 days of
such notice, the permittee shall submit a time schedule to the Director for modifying the SPPP
to meet minimum requirements. The permittee shall provide certification in writing to the
Director that the changes have been made.
9. SPPP Implementation. The permittee shall implement the Stormwater Pollution Prevention
Plan and all appropriate BMPs consistent with the provisions of this permit, in order to control
contaminants entering surface waters via stormwater. Implementation of the SPPP shall
include documentation of all monitoring, measurements, inspections, maintenance activities,
and training provided to employees, including the log of the sampling data and of actions taken
to implement BMPs associated with the industrial activities, including vehicle maintenance
activities. Such documentation shall be kept on-site for a period of five (5) years and made
available to the Director or the Director's authorized representative immediately upon request.
