Site Plan
The WestROck Paper Mill is located at 100 Gaston Road, Roanoke Rapids, North Carolina
approximately 1 mile west of Interstate 95. Approximate GPS coordinates are 36-28-30 N and
77-38-30 W. The facility is located adjacent to the Roanoke River and operates under NPDES
Permit NCS000106.
Stormwater from the facility is collected in three sub -basins. The largest sub -basin contains
about 155.8 acres and includes the paper mill proper, the woodyard chip piles and the
wastewater treatment plant (NPDES NC0000752). Petroleum products on site include tall oil,
diesel fuel, 46 fuel oil, hydraulic oil and various lubricants.
A number of chemicals are stored on site as well. These tanks are surrounded by containments
and all areas are drained to our wastewater treatment facility. These chemicals include, but are
not limited to, sulfuric acid, caustic soda, defoamer, sodium hypochlorite and sodium
hydroxide. A site diagram showing the location of these tanks is included under the Chemical
Storage Area tab in this document.
A small portion of the north side of the mill flows untreated directly into the Roanoke River.
This area is known as the "Storeroom" sub -basin and contains about 0.97 acres. There are no
process areas in this portion of the mill property. In December 2010 as part of implementation
of the Best Management Practices, a block and gravel structure was installed at this discharge
location.
The third sub -basin drainage area consists of the mill employee parking areas, main office,
maintenance shop, shipping building, trailer parking areas and truck scales. This sub -basin
contains approximately 12.75 acres and drains in a southerly direction to a series of stormwater
conveyance pipes and ditches and is known as the "Tent Cutfall" sub -basin. Block and gravel
devices, check dams and silt fences were installed in December 2010 as part of the
implementation of Best Management Practices as submitted and approved by the State of
North Carolina. This discharge area combines downstream with a larger stormwater drainage
area of approximately 770 acres from the City of Roanoke Rapids.
WestRock purchased the facility from KapStone Kraft Paper in November 2019. The facility has
been in continuous operation since 1907 when it was first constructed by Roanoke Paper
Manufacturing. WestRock produces bulk rolls of unbleached kraft paper at this facility.

Storage Practices
Loading and Unloading Activities
Oil and chemicals are located in storage tanks within the mill. A map of their locations is
contained within the Stormwater Plan and the Emergency Action Plan. The chemical tanks are
filled from rail cars or tractor trailers. The unloading points are on concrete pads that drain to
our process sewer in case of any spills. All chemical tanks are on concrete pads that drain to
the process sewer or within concrete containment areas. These containment areas have locked
valves that also drain to the process sewer and are inspected on a regular basis and after rain
events. Records of these inspections are kept in the Maintenance Department files and an
electronic copy of EOHS personnel activities is kept on the mill's G drive.
Tote bins of chemicals are stored at the Spra-White slab. Empty tote bins are also stored at this
location. This area drains to the mill's wastewater treatment system.
Outdoor Process Areas
Logs, bark, chips and dust are brought into the mill through the scale house and stored on the
mill site. These items are delivered to various process areas by use of transfer screws or
conveyer belts. Storage areas for these items have drains and ditches to convey any runoff to
the stormwater holding pond adjacent to the Carolina Chips maintenance building. The
collected stormwater is pumped into the mill's Emergency Pond and then introduced from
there into the wastewater treatment system.
Dust Control Process
Most of the mill roads in the Tent Outfall Sub -Basin are gravel. Dust is controlled by spraying
the roads with untreated river water. The mill uses an outside contractor to provide this
service. Typical application is three days per week during dry weather months.
Spill Response
An SPCC plan has been developed for the mill that contains necessary information in the event
of a spill and recommended response actions to betaken. The mill has an Emergency Response
Team that is trained for spill response. The SPCC plan can be found in the EOHS department.

On Site vehicle Maintenance Monitoring
Vehicle maintenance is performed on site in what is known internally as the "Truck Shop" and
the Woodyard Maintenance Shop. These areas are enclosed from the weather. Spills are
cleaned up with approved absorbent materials. Internal drains in the buildings go to the mill's
process sewer. Used oil is collected in drums and disposed of by a contractor.
General spills from vehicles and heavy equipment operating within the mill are cleaned up with
sawdust. The contaminated sawdust is then collected and burned in the boiler.
Waste Disposal Practices
The mill has a lined landfill that is permitted to receive primary clarifier residuals, flyash and
lime mud. The landfill consists of three out of four permitted phases with a current footprint of
approximately 35 acres. The fourth phase will be constructed when the current cells near
capacity. Leachate from the landfill is collected and gravity fed to the wastewater treatment
facility.
All trash is placed in dumpsters located throughout the mill property to be hauled off site and
processed by an outside contractor.

Subject: RE: KapStone Kraft NCS000106
Dear Ms. Ransmeier,
Thanks For being available on such short notice For our unscheduled visit. It really helps the permitters when
we can see the site conditions, Based on your note, we are in agreement as to the Storeroom Outfall and as to the
sample point for the Tent Outfall. I've re -stated below your points just to confirm our agreement on them; please
contact us if I have missed any minor point.
I have relayed our conversation and my observations at Kapstone to your permit writer, Brian Lowther, and to
our supervisor, Bradley Bennett. Please take this note as written confirmation of certain comments I made while on
your site. Specifically, as to your current coverage under the expired Individual permit, NCS000106, you are authorized
for Representative Outfall Status from this time forward. DWQ will consider the Tent Outfall representative of the
stormwater discharges from both the Tent Outfall and the Storeroom Outfall, until and unless significant changes in on -
site activities suggest that the Representative Outfall Status is no longer appropriate, Scheduled analytical samples
need only be taken for the Tent Outfall. Visual monitoring is to be continued at both outfalls. Further, we are in
agreement with the relocation of the sample point for flows from the Tent Outfall to a location further downstream
than previously located. As you note and as we discussed, the new location will be close to, but still upstream of the
junction with the large flows from off site, i.e. the city stormwater flows,
As to provisions in the pending renewed permit, we intend that the Representative Outfall Status will continue
for the Tent Outfall, and we will so note in the transmittal letter that will accompany the renewed permit.
Administratively it has been our practice to address the granting of Representative Oufall Status by separate letter
outside of the permit text, and we propose to continue that practice if you do not object. Similarly, on large and
complicated sites we typically do not direct the exact location of stormwater sampling, unless we see a need to, We are
in agreement with the current proposed location further downstream, and are agreeable for that location to be
continued under the renewed permit, Please contact us for concurrence if you subsequently judge that another location
might be more representative of the stormwater flows from your site,
Ken Pickle

Subject: Storm Sewers
Had a discussion with Ben about the storm sewer manholes between maintenance and B-mill. He asked about
management of the manholes and the rolls, etc. I told him there were two ways to manage them with our present set
up*
1.
Leave
them
uncovered
and when
something happens
call shipping to cover the manholes.
2.
Leave
them
covered up
and move
them when it rains,
etc.
I told him #1 was the practice we were following. He was not comfortable with this, practice and preferred them to stay
covered and move when necessary... i.e. #2. I told him we would follow that and the storm water manager would take
responsibility. If you have any problems or concerns or comments, lets discuss.
I also asked
about the manhole project that
has been presented multiple
times. It is still "on the list" but hasn't made
the cut. 42
is the more protective but at the
same time more inconvenient
practice and perhaps the more inconvenient
we make it,
the more visible the project will
be and possibly help make it
make the cut.

Mike I
think it is a mistake to
leave the rolls on the grates,
Water gets too deep from a rain event and they won't be able
to get
the lift truck in to remove the roll. Almost got into a
tractor trailer rig door during CMO.
I'll document this practice to the Storm water manual and who to contact to get rolls moved.

To Whom It May Concern;
As required by the Division of Water Quality, enclosed are three copies of the KapStone Kraft

May 31, 2019. The permit number is NCS000106. Results are for the monitoring period February

holding the above referenced permit. As such, the Roanoke Rapids Mill is still owned by KapS tone
Paper and it is proper to file applications and maintain permits as KapStone Paper until further

Feasibility Study and BMP Summary
In July 2010 a Stormwater Best Management Plan was submitted to NCDWQ. The study was
conducted by Eco Engineering, a division of John McAdams Company of Durham, NC. Approval
from NCDENR was received on August 26, 2010.
A copy of the entire submittal is located in the EHS office. The following erosion control devices
were installed in December 2010.
o Check dams were installed in the large ditches surrounding the Scale House
• A six inch berm of #57 stone was placed around the perimeter of the ditches
• Grass was allowed to grow lining the ditches
• Devices were constructed in the Trailer Yard by raising the existing drain 16 inches using
concrete block surrounded by 457 stone. A chain was installed to prevent vehicular
traffic in this area.
• A check dam consisting of railroad ballast was installed at the Storeroom Discharge. #57
stone was added upstream of the ballast to serve as a filtration device and to facilitate
cleaning.
• When needed, erosion control stone is removed and replaced with fresh stone. The
used stone is taken to the onsite landfill for use in internal roadways.
• In 2017 Carolina Chips constructed a new woodyard on property they lease from
WestRock. The old woodyard was abandoned and demolished as part of the project. A
new stormwater pond and pumping station were installed and is maintained by
WestRock. This stormwater is pumped to our wastewater treatment facility via our
"Emergency Pond"
Annual Environmental Awareness Training is conducted for each employee of the WestRock
Roanoke Rapids MiII. Training documentation is maintained by the EHS Department.
The mill has a Hazardous Materials Response Team that receives 32 hours of training annually.
8 hours of that training is Technician Level Training.
The mill maintains two boats with outboard motors and 1,000 feet of floating boom onsite as
part of the required Facility Response Plan and SPCC Plan.
Only 13.7
acres of the Roanoke
Rapids Mill drains to the wastewater treatment facility. In the
event of
a spill, personnel are trained
to immediately attempt
to stop or control the source of
the spill.
They are instructed to
take measures to contain and
clean up any spilled materials

utilizing the absorbent materials that are stored in the hazmat truck. Since bulk storage
containers are located outside, particular attention must be paid to protecting the drainage
pathways in the direction of the spill. Personnel will immediately insure that mats are deployed
over nearby drop inlets and in sufficient quantity to contain all spilled material. Use of material
to dike, dam or divert the spill may also be used to prevent the spill from entering storm drains.
Personnel shall document the incident and response activities.
In 2019, two "SafeDrain" devices were installed in stormwater drains at the storeroom and in
the roadway between B-mill and the Main Lab building and one stormwater manhole was
raised in order to reduce potential exposure in the event of a stock spill/overflow.

Secondary Containment
The Roanoke Rapids MiII is required to maintain a Spill Prevention Controls and
Countermeasures Plan and a Facility Response Plan due to the volume of petroleum product
vessels onsite. This document addresses secondary containment within the mill property and a
copy is kept in the EHS department. Additionally, for areas that runoff is conveyed to the
wastewater treatment system, tertiary containment could be provided within the wastewater
treatment system by ceasing discharge of the system until cleanup and remediation takes place
as outlined in the Facility Response Plan.
Methods of secondary containment at the facility include a combination of structures (e.g. dike,
berm, local secondary containment), drainage systems (process sewers to the WWTP), and spill
response materials to prevent oil from reaching surface waters.

Spill Prevention and Response Plan
Environmental Awareness Training is conducted annually for each employee of the Roanoke
Rapids Mill. Training documentation is kept in the EHS department.
The Roanoke Rapids Mill has a Haz-Mat Team that receives 32 hours of training annually, 8
hours of which are specified as Technician level Training. This team maintains two boats with
outboard motors and 1,000 feet of boom in the event response is needed in the Roanoke River,
The Roanoke Rapids MiII is required to have a Spill Prevention Controls and Countermeasures
plan and a Facility Response Plan. These documents are utilized to meet the requirements of
Spill Prevention and Response within our Stormwater Pollution Prevention Plan and
Stormwater Management Plan.
All but 13.7 acres of the Roanoke Rapids Mill site drains to the wastewater treatment plant.
The mill has constructed erosion control devices throughout those 13.7 acres under the
guidance of the feasibility study and BMP recommendations from 2010.
In case of a spill:
Personnel are trained to immediately attempt to stop or control the source of the spill. They
shall take measure to contain and clean up any spilled materials utilizing the absorbent
materials that are stored in the hazmat truck. Since bulk storage containers are located outside
particular attention shall be paid to protecting the drainage pathways in the direction of the
spill. Personnel will immediately ensure that mats are deployed over nearby inlets and
absorbent pads are deployed in sufficient quantities to contain and/or absorb all spilled
material. Use of material to dike, dam or divert the spill may also be used if necessary to
prevent the spill from entering the storm drain. Personnel shall document the incident and
response activities.

Preventive Maintenance and Good Housekeeping
A number of Stormwater Control Measures (SCM) and Best Management Practices (BMP) have
been installed at the facility over the years. These devices are informally monitored through
various inspection rounds that are performed by mill personnel as part of their assigned duties.
A written inspection shall be conducted quarterly by EHS personnel and documented. Any
required repairs or modifications to control devices should be entered in the mill's maintenance
work request system.
Good housekeeping is integral to a safe work environment for mill personnel. Constant focus is
placed on housekeeping and general cleanliness of work areas. The dedication of mill
employees to look out for each other's safety carries over to their observational skills and
freedom to point out when potentially harmful situations exist. This includes situations that
could have negative impacts on the environment. These conditions are given priority in the
mill's work request system and are targeted to be repaired or remediated within ten days of
notification.

PART II MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN (SWPPP)
The permittee shall develop and implement a Stormwater Pollution Prevention Plan
(SWPPP). The SWPPP shall be maintained on site unless exempted from this requirement
by the Division. The SWPPP is public information in accordance with Part III, Standard
Conditions, Section E, paragraph 3 of this permit. The SWPPP 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:
i, the facility's location in relation to transportation routes and surface
waters; and
ii. 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.
The general location map shall identify whether any receiving waters are impaired
on the state 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.
(c) A site map drawn at a scale sufficient to clearly depict:
i. The site property boundary;
ii. Site topography and finished grade;
iii. Buildings;
iv. Industrial activity areas (including storage of materials, disposal areas,
process areas, loading and unloading areas, and haul roads);
v. Stormwater discharge outfalls (latitudes and longitudes must be listed);
vi. Drainage area for each outfall;
vii. Direction of flow in each drainage area;
viii. All on -site and adjacent surface waters and wetlands;
ix. All drainage features and structures;
x. Stormwater Control Measures (SCMs);
xi. Stormwater Best Management Practices (BMPs); and
xii. Impervious surfaces.
Page 3 of 3 I

Permit No, NCS000106
Additionally, the site map must indicate the percentage of each drainage area that is
impervious. A graphic scale and north arrow are also required components.
(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.
(e) Certification that the stormwater on have been evaluated for the presence of
non-stormwater discharges. The permittee shall re -certify annually that the
stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the
requirements found in Part III, Standard Conditions, Section B, Paragraph 3.
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. 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.
Specific Controls
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 maintained in the
closed position and secured closed with a locking mechanism.
Inspections
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, and said observations shall be documented
prior to release of the accumulated stormwater. Accumulated
stormwater may be released if found to be uncontaminated by any
material. Accumulated stormwater found to be contaminated shall not be
Page 4 of 31

Permit No. NCS000106
released from the containment area. Documentation shall include the
individual malting the observation, the description of the accumulated
stormwater and observations, and the method, date and time of the
release or disposal.
Exceptions
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. The Division may allow
exceptions to secondary containment requirements for mobile refuelers,
as with the exemption provided by amendments to federal SPCC
regulations, as long as appropriate spill containment and/or diversionary
structures or equipment is used to prevent discharge to surface waters.
Exceptions do not apply to refuelers or other mobile tankage used
primarily as bulls liquid material storage in a fixed location in place of
stationary containers.
(c) SCM/BMP Summary. A listing of structural stormwater Control Measures (SCM)
and non-structural Best Management Practices (BMPs) on site shall be provided.
The installation and implementation of SCMs and/or 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 SCM/BMP Summary shall include a written record of
the specific rationale for installation and implementation of the selected site SCMs
and/or BMPs. The SCM/BMP Summary shall be reviewed and updated annually.
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 SCMs and non-structural BMPs.
Page 5 of 31

Permit No, NCS000106
The program shall establish specific schedules for inspections, maintenance, and
housekeeping activities for 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
SWPPP. Semi-annual inspections of material handling areas and regular cleaning
schedules of these areas shall be incorporated into the program. Timely compliance
with the established schedules for inspections, maintenance, and housekeeping shall be
recorded and maintained in the SWPPP.
5. Facility Inspections. Inspections of the facility 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).
These facility inspections are different from, and in addition to, the stormwater
discharge characteristic monitoring at the outfalls required in Part II B and C of this
permit.
6. Employee Training. Training progratns addressing spill response and cleanup
procedures, preventative maintenance and good housekeeping activities, and facility
inspections 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.
Responsible Party. The SWPPP shall identify a specific position or positions
responsible for the overall coordination, development, implementation, and revision of
the SWPPP. Responsibilities for all components of the SWPPP shall be documented and
position assignments provided.
8. SWPPP Amendment and Annual Update. The permittee shall amend the SWPPP
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 SWPPP shall be reviewed and updated on an annual basis. The annual update
shall include:
(a) A"" eint­nA list of significant spills or leaks of pollutants fot• the previous
three (3) years, or the notation that no spills have occurred;
(b) A written certification that the stormwater outfalls have been evaluated for
the presence of non-stormwater discharges;
(c) A documented re-evaluation of the effectiveness of the on -site SCMs and
BMPs in minimizing the contamination of stormwater runoff, including a
summarization of all SCM inspections conducted throughout the year
preceding the annual update;
Page 6 of 31

Permit No. NCs000106
(d) A statement that annual training requirements were met in the past year;
and
(e) A review and comparison of sample analytical data to benchmark values (if
applicable) over the past year, including an evaluation of Tiered Response
status. The permittee shall use the Division's Generic Annual Data
Monitoring Report (DMR) Form, available from the Stormwater Permitting
Program's website (See: https://deq.nc.gov/about/divisions/energy-
mineral-land-resources/nn des-stormwater-individual).
The Director may notify the permittee when the SWPPP does not meet one or more of
the minimum requirements of the permit. Within 30 days of such notice, the permittee
shall submit a time schedule to the Director for modifying the SWPPP to meet minimum
requirements. The permittee shall provide certification in writing (in accordance with
Part III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
9. SWPPP Implementation. The permittee shall implement the SWPPP and all
appropriate SCMs and BMPs consistent with the provisions of this permit, in order to
control contaminants entering surface waters via stormwater. Implementation of the
SWPPP 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 SCMs and 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 Division
immediately upon request.
SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1.
All analytical monitoring shall be performed during a measurable storm event at eac
stormwater discharge outfall (SDO). Only SDOs discharging stormwater associated with
industrial activity must be sampled (See Definitions).
A measurable storm event is a storm event that results in an actual discharge from the
permitted site outfall0 The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a
shorter interval is representative for local storm events during the sampling period, and the
permittee obtains approval from the local DEMLR Regional Engineer. See Definitions.
The permittee shall compare monitoring results to the benchmark values in Table 1.
Exceedances of benchmark values require the permittee to increase monitoring, increase
management actions, increase record keeping, and/or install SCMs and BMPs in a tiered
program. See the descriptions of Tier One, Tier Two, and Tier Three response actions below
in Table 3, Table 4, and Table 5.
If the facility is monitoring monthly because of Tier Two or Three response actions under the
previous permit, the facility shall continue a monthly monitoring and reporting schedule in
Tier Two or Tier Three status until relieved by the provisions of this permit or the Division.
Page 7 of 31

Permit No. NCS000106
In the event that the Division releases the permittee from continued monthly monitoring and
reporting under Tier Two or Tier Three, the Division's release letter may remain in effect
through subsequent reissuance of this permit, unless the release letter provides for other
conditions or duration. If the permittee obtains a written release letter from the Division
which approves modification of Tier 2 or Tier 3 monitoring requirements, then the letter shall
become an enforceable component of this permit.
The benchmark values in Table 1 are not permit limits but shall be used as guidelines for
implementation and evaluation of the permittee's SWPPP. An exceedance of a stormwater
benchmark value is not a permit violation; however, failure to respond to the exceedance as
outlined in this permit is a violation of permit conditions.
Please note that the parameters in the last two rows in Table 1 (non -polar oil and grease
and new motor/hydraulic oil usage) are only required for outfalls that discharge runoff
from vehicle or equipment maintenance areas in which more than 55 gallons of new motor
oil and/or hydraulic oil are used per month when averaged over the calendar year.

1 Measurement Frequency: Twice per year (unless other provisions of this permit prompt monthly
sampling) during a treasurable storm event, until either another permit is issued for this facility or
until this permit is revoked or rescinded. If the facility is monitoring monthly because of Tier Two or
Three response actions under the previous permit, the facility shall continue a monthly monitoring
and reporting schedule in Tier Two or Tier Three status until relieved by the provisions of this
permit or the Division.
2 Grab samples shall be collected within the first 30 minutes of discharge. When physical separation
between outfalls prevents collecting all samples within the first 30 minutes, sampling shall begin within
the first 30 minutes, and shall continue until completed,
Page 8 of 31

Permit No. NCS000106
Sample Location: Samples shall be collected at each stormwater discharge outfall (SDO) unless
representative outfall status (ROS) has been granted. A copy of the Divisions letter granting ROS shall
be kept on site.
For each sampled measurable storm event, the total precipitation must be recorded. An on -site rain
gauge is required. Where isolated sites are unmanned for extended periods of time, a local rain gauge
reading may be substituted for an on -site reading.
This parameter is only required for outfalls that discharge runoff from vehicle / equipment maintenance
areas in which more than 55 gallons of new motor or hydraulic oil are used per month when
averaged over the calendar year.
The permittee shall complete the analytical samplings in accordance with the schedule
specified below in Table 2, unless adverse weather conditions prevent sample collection
(see Adverse Weather in Definitions). Sampling is not required outside of the facility's
normal operating hours. A minimum of 60 days must separate Period 1 and Period 2
sample dates, unless monthly monitoring has been instituted under a "Tier Two"
response. Inability to sample because of adverse weather conditions must be documented
in the SWPPP and recorded on the DMR. The permittee must report the results from each
sample taken within the monitoring period (see Part III, Section E). However, for purposes
of benchmark comparison and Tiered response actions, the permittee shall use the
analytical results from the first sample with valid results within the monitoring period.

1 Maintain semi-annual monitoring until either another permit is issued for this facility or mail this
permit is revolted or rescinded. The permittee must submit an application for renewal of coverage
before the submittal deadline (180 days before expiration) to be considered for renewed coverage
under the permit. The permittee must continue analytical monitoring throughout the permit
renewal process, even if a renewal permit is not issued until after expiration of this permit.
2 If no discharge occurs during the sampling period, the permittee must submit a monitoring report
indicating "No Flow" or "No Discharge' within 30 days of the end of the sampling period.
3 Monitoring periods remain consistent through the permit term and through the renewal process. The
first sampling period begins in Period 1 on January 1, 2021.
Failure to monitor semi-annually per permit conditions may result in the Division
requiring monthly monitoring for all parameters for a specified time period. "No
discharge" from an outfall during a monitoring period does not constitute failure to
monitor, as long as it is properly recorded and reported.

Then the permittee shall:
1. Conduct a stormwater management inspection of the facility within two weeks of receiving sampling
results.
2. Identify and evaluate possible causes of the benchmark value exceedance.
3. Evaluate and select specific source controls, operational controls, and/or physical improvements to
reduce concentrations of the parameter(s) of concern and bring concentrations within the benchmark
range.
4. Implement the selected controls/improvements within two months of the inspection.
S. Record each instance of a Tier One response in the SWPPP. Include the date and value of the benchmark
exceedance, the inspection date, the personnel conducting the inspection, the selected actions, and the
date the selected actions were implemented.
Note: A benchmark exceedance triggers a Tier One response for each parameter.
Table 4. Tier Two Requirements
If the first valid sampling results from two consecutive monitoring periods (omitting periods with no
discharge) are above the benchmark values, or outside of the benchmark range, for any specific parameter at
Then the permittee shall•
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring and reporting for all analytical monitoring parameters. The
permittee shall conduct monthly monitoring at every outfall where a sampling result exceeded the
benchmark value for two consecutive samples. Monthly (analytical and qualitative) monitoring shall
continue until three consecutive sample results are below the benchmark values or within benchmark
range.
3. If no discharge occurs during the sampling period, the permittee is required to submit a monthly
monitoring report indicating "No Flow" to comply with reporting requirements.
4. Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances, exercise the
option of contacting the DEMLR Regional Engineer as provided below in Tier Three. The Regional
Engineer may direct the response actions on the part of the permittee as provided in Tier Three,
including reduced or additional sampling parameters or frequency.
S. Maintain a record of the Tier Two response in the SWPPP.
6. Continue Tier Two response obligations throughout the permit renewal Drocess.

If the valid sampling results required for the permit monitoring periods exceed the benchmark value, or
are outside the benchmark range, for any specific parameter at any specific outfall on four occasions, the
permittee shall notify the DEMLR Regional Engineer in writing within 30 days of receipt of the fourth
Then the Division may, at minimum, require the permittee:
• Revise, increase, or decrease the monitoring and reporting frequency for some or all of the parameters
herein;
® Sampling of additional or substitute parameters;
• Install structural stormwater controls;
® Implement other stormwater control measures;
® Perform upstream and downstream monitoring to characterize impacts on receiving waters;
® Implement site modifications to qualify for a No Exposure Exclusion;
• Continue Tier Three obligations through the nermit renewal nrncess.
This site discharges to impaired waters experiencing problems with fish tissue mercury. If
the Division institutes further actions, which may include the development of a Total
Maximum Daily Load (TMDL) for this segment of Roanoke River, then the Division will
consider your monitoring results in determining whether additional SCMs and/or BMPs
are needed to control the pollutant(s) of concern to the maximum extent practicable.
If additional SCMs and/or BMPs are needed to achieve the required level of control, the
permittee will be notified in writing and required to (1) develop a strategy for
implementing appropriate SCMs and/or BMPs, and (2) submit a timetable for
incorporation of those SCMs and/or BMPs into the Stormwater Pollution Prevention Plan,
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
The purpose of qualitative monitoring is to evaluate the effectiveness of the SWPPP and
identify new potential sources of stormwater pollution. Qualitative monitoring of
stormwater outfalls must be performed during a measurable storm event.
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status. Qualitative monitoring shall be performed semi-annually
during required analytical monitoring events (unless the permittee is required to perform
further qualitative monitoring per the Qualitative Monitoring Response, below). Inability
to monitor because of adverse weather conditions must be documented in the SWPPP and
recorded on the Qualitative Monitoring Report form (see Adverse Weather in Definitions).
Only SDOs discharging stormwater associated with industrial activity must be monitored
(See Definitions).
In the event an atypical condition is noted at a stormwater discharge outfall, the permittee
shall document the suspected cause of the condition and any actions taken in response to
the discovery. This documentation shall be maintained with the SWPPP.

continue qualitative monitoring throughout the permit renewal process until a new permit is issued.
2 Monitoring Location: Qualitative monitoring shall be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status.
A minimum of 60 days must separate monitoring dates, unless additional sampling has
been instituted as part of other analytical monitoring requirements in this permit.
If the permittee's qualitative monitoring indicates that existing stormwater SCMs and/or
BMPs are ineffective, or that significant stormwater contamination is present, the
permittee shall investigate potential causes, evaluate the feasibility of corrective actions,
and implement those corrective actions within 60 days, per the Qualitative Monitoring
Response in Table 7. A written record of the permittee's investigation, evaluation, and
response actions shall be kept in the SWPPP.
Table 7.
Qualitative monitoring is for the purposes of evaluating SWPPP effectiveness, identifying new
potential sources of stormwater pollution, and prompting the permittee's response to pollution. If
the permittee repeatedly fails to respond effectively to correct problems identified by qualitative
monitoring, or if the discharge causes or contributes to a water quality standard violation, then the
Division may, at minimum, require the permittee:
• Revise, increase, or decrease the monitoring frequency for some or all parameters
(analytical or qualitative);
• Install structural stormwater controls;
• Implement other stormwater control measures;
• Perform upstream and downstream monitoring to characterize impacts on receiving
waters; or
• Implement site modifications to qualify for a No Exposure Exclusion,

Kapstone Paper
DWQ BMP Management Plan
Description and BrrclC 1'01111rl
fie Kapstone Kraft Paper Corporation in is located at 100 Gaston Road in Roanoke
Rapids, North Carolina. This site functions under NPDES Stornnwater Permit
NCS000106 as required by North Carolina General Statute 143-215 .l and the
Memorandum of Agreement between the State of North Carolina and the U.S.
Environmental Protection Agency dated October 15, 2007.
The mill is adjacent to the Roanoke River and generally drains to the Roanoke River
through three major sub -basins. The largest sub -basin, which includes the actual paper
mill, wood chip piles, and portions of the "yard" area drains into the mill's wastewater
treatment plant. A small north portion of the mill site drains untreated directly into the
Roanoke River. This sub -basin is known as the "Storeroom" sub -basin. The third sub -
basin drainage area consists of the mill's employee parking, main office, maintenance
shop, shipping building, trailer parking area, and the truck scales. This area drains
generally south to a series of stormwater conveyance pipes and ditches and is known as
the "Pent" sub -basin. Runoff from this system is untreated and combines with a larger
drainage area from the City of Roanoke Rapids before flowing into the Roanoke River.
This report focuses on the Tent Sub -Basin which is the representative outfall for
monitoring. ']'his report outlines a series of Best Management Practices that are intended
to comply with the permit and with the water quality aspects of site runoff.
The finat NPDES permit issued to Kapstone dated July 24, 2009 includes a requirement
in Section 13 that a BMP Management Plan and Implementation be developed within 2
years of the permit being issued. This report is to serve as the BMP Management Plan
which must be submitted to the Division of Water Quality no later than February 28,
2010.
A�ater• r7unlitV Stmrrlrn•rls onrC Testirr�
Currently the mill takes grab samples during storm events to test for water quality
parameters. "1"his semi -amoral quantitative nnouitoring sh•ategy remains the sanne under
the most current NPDES Permit, however, as noted in Section I if this report via email
correspondence with DWQ, the sampling location of the Tent Outfall was changed in the
summer of 2009 to a more downstream location.
The current water quality parameters tested in the quantitative motoring strategy are
Chemical Oxygen Demand (COD), 'hotal Susperndcd Solids (TSS), Phosphorous (P),
Lead, Ph, and Oil & Grease. As is shown in the latest September 2009 testing results, all
of these parameters are below the thresholds required by the permit.

�a fisting Conditions
In the Tcut Sub -Basin, stornnwater runoff is conveyed generally south over paved areas,
gravel areas, open areas, and grassed areas into a series of pipes and conveyance ditches
to the south of the site. This stornnvater conveyance system generally does not
experience flooding and is constructed for conveyance of storm flows off of the property.
I'lle cover conditions for the Tent Sub -Basin vary throughout the drainage area from
grass, to concrete pavement, to gravel parking, to asphalt pavement. Some portions of
fhe drainage area have curb and gutter while others sheet flow fron paved areas.
Based on visual observations, the main areas within the "Pent Sub -Basin likely
contributing to water quality problems are the trailer parking area and the log/chip truck
entrance/exit road.
Proposed Aleascmes
The prclinninary measures presented in this report are to be implemented in cottjunctial
with Kapstone's current Best Management Practices which are mainly focused oil spill
prevention and containment. The BMPs presented in this report have the main goal of
reducing stormwater pollutants from entering the waterways via settling, infiltration,
direct removal, and biological/vegetative uptake.
The measures presented in the BMP Management Plan Report are divided into three main
categories: prevention, infiltration/settling, and capture. A comprehensive strategy
employing all of these techniques to reduce stornnwater pollutants will be needed for the
Teat Sub -Basin area. The measures presented below are intended to work together to
help prevent pollutant runoff, allow infiltration and settling of the pollutant runoff, and
capture and remove the pollutant runoff.
The goal of this report is to recommend effective measures that will provide a direct
benefit to reducing the pollutant loads in the mill's runoff from the Tent Sub -Basin. The
measures presented below are intended to be relatively cost-effective measures, have
simple maintenance requirements, and not take up valuable areas of the mill's operations.
Large construction expenses such as a stormwater wet pond, bioretentio❑ area, or a
constructed wetland (traditional structural BMPs) are not recommended at this time.
Please note that many of the measures presented below are based on specific proprietary
commercial products from ACP Environmental. Product name brands and brochures
from ACP lnvironmental are presented to demonstrate the idea and concept of each
measure and are not necessarily used as a recommendation of one specific product.
Many companies specialize in stornnwater management and erosion/scclinient control
measures.

Prevention d9easuies
The Prevention measures presented iu this section are intended to help prevent pollutants
from being picked up by rain events and from entering the stormwater flows before the
flows enter the conveyance system. The goal of the Prevention measures is source
reduction of pollutants.
Ground Cover
A strategy of enhanced ground cover with the "feat Sub -Basin area could be implemented
to help reduce sediment runoff in large storm events. Any open or grassed areas within
the Tent Sub -Basin could be seeded, reseeded, provided with an excelsior matting as
required, and maintained such to limit the amount of sediment that night runoff from
these areas. A higher mowing length of the existing grassed areas or possible changing
the type of turf grass seed for the landscaping could change the runoff characteristics of
these areas.
Any gravel or impervious areas within the Tent Sub -Basin that could be converted to a
grass or landscape area would also help to reduce runoff and pollutants.
Truck Scale Area
All trucks delivering logs or wood chips to the mill pass over the scales along the
southwest perimeter of the site. Periodically these scales are cleaned of wood, road, and
truck debris. Runoff flows directly into the open stormwater conveyance ditch system
adjacent to the scales. Measures to contain the runoff from the scale operation could
potentially reduce the loading of large debris and pollutants from entering the stormwater
system. A series of check dams and silt fence could be installed to slow, filter, and catch
the runoff and prevent the larger pollutants from entering the stormwater systent
Biftlhv�tion/Settiir�e Measures
7"he lufiltiation/Settling measures presented iu Chis report are inteudcd to promote
iuf lU•ation of the stormwater flow into Che soil and slow die velociti¢s of the stormwater
flows to allow settling of pollutants.
I?orebays/Check Dams
fhc Tent Sub -Basin has several open conveyance ditches along the perimeters of parking
areas and roadways. The stormwater in these ditches could be slowed via a series of
check dams, forebays, and fiber filtration tubes. These measures would allow the
stormwater to be conveyed through the site, but would reduce the velocity of the flow and
allow some settling of pollutants and filtration through the stone check dams, fiber
filtration tubes, or straw wattles that could be installed in the swales.

Additionally in paved areas where there is no curb and gutter, a small washed stone filter
berm or triangular silt dike could be installed to slow runoff directly from paved areas
before it enters the conveyance ditches.
Floc Logs
As a possible future measure, polyaerylamide (PAM) sediment control products such as
floc logs could be installed in select catch basins where the majority of sediment laden
runoff is entering the stormwater system. These floc logs work to stabilize and reduce
the loss of fine soil particles in runoff by chemically binding smaller particles together
into larger particles that settle out of the stormwater runoff easier. Floc logs combined
with check dams and forebays would enhance the settling capacity of the stormwater
conveyance system and reduce pollutants from the runoff.
Vegetation in Ditches
Currently the storrilwater conveyance ditches and swales are kept vegetated to the extent
possible. However, the grass in these areas is cut very short and close to the ground. A
strategy for allowing the vegetation in these ditches and conveyance channels to grow
higher and provide more of a riparian buffer area within the conveyance channel would
reduce pollutant loading and slow runoff. A wet meadow seed mix could be used in
these areas to promote the growth of vegetation similar to a traditional riparian buffer
area.
Cnr�dur•e Mensurea
"The Capture measures are intended to directly capture and physically remove pollutants
from stomwater flows. These measure are somewhat more labor and inspection
intensive due to the potential for increased flooding if the measures are not maintained
properly, but the potential benefit of these items should be considered.
Catch Basin Inserts and Inlet Protection
The drop inlets and catch basins in the pipes portions of the stormwater conveyance
system for the "Tent Sub -Basin could be fitted with measures to capture sediment and
pollutants as they enter the closed portion of the stormwater conveyance system. Catch
basin inserts such as catch basin filters installed in the catch basin structure, above-
ground inlet protectors such as a Gutterbuddy, GutterGator, GrateGators, or Gutterl3F.,L.
could be used to block and catch sediment and pollutant laden runoff without
significantly compromising the flow capacity of the system.
Any catch basin inserts or inlet protection measures would need to be installed,
maintained, and protected such that vehicles would avoid driving over and damaging the
measures or installed such that the measures could withstand vehicle traffic without
damage.

f1 drlftloival IYleasar es
Additional measures can be implemented by the mill for prevention of pollutants in the
stormwatcr runoff. A plan to provide manually or pneumatically controlled shut-off
valves for stormwatcr catch basins and piping systems located in the chemical storage
tanks is being considered by the mill.
Summar•Y
This BMP Management Plan is intended to provide cost-effective and relatively low
maintenance practices for the Kapstone Mill with the goal to reduce stormwater pollutant
loads from the "Pent Sub -Basin.
Thrce chapters from the NC DWQ BMP Design Manual are included in this report to
give general design and conceptual guidance for implementation of measures such as
61ter strips, grassed swales, and buffer areas.

pear Ms. Ransmeier,
'thanks for being available on such short notice for our unscheduled visit. It really helps the permitters when
we can see the site conditions. Based on your note, we are in agreement as to the Storeroom Outfall and as to the
sample point for the Tent Outfall. I've re -stated below your points just to confirm our agreement on them; please
contact us if I have missed any minor point.
I have relayed our conversation and my observations at Kapstone to your permit writer, Brian Lowther, and to
our supervisor, Bradley Bennett. Please take this note as written confirmation of certain comments I made while on
your site. Specifically, as to your current coverage under the expired individual permit, NC5000106, you are authorized
for Representative OutfaII Status from this time forward. DWQ will consider the Tent Outfall representative of the
stormwater discharges from both the Tent Outfall and the Storeroom Outfall, until and unless significant changes in on.
site activities suggest that the Representative Outfall Status is no longer appropriate. Scheduled analytical samples
need only be taken for the Tent Outfall. Visual monitoring is to be continued at both outfalls. further, we are in
agreement with the relocation of the sample point for flows from the Tent Outfall to a location further downstream
than previously located. As you note and as we discussed, the new location will be close to, but still upstream of the
junction with the large flows from off site, i,e. the city stormwater flows,
As to provisions in the pending renewed permit, we intend that the Representative Outfall Status will continue
for the Tent Outfall, and we will so note in the transmittal letter that will accompany the renewed permit.
Administratively it has been our practice to address the granting of Representative Oufall Status by separate letter
outside of the permit text, and we propose to continue that practice if you do not object. Similarly, on large and
complicated sites we typically do not direct the exact location of stormwater sampling, unless we see a need to. We are
in agreement with the current proposed location further downstream, and are agreeable for that location to be
continued under the renewed permit. Please contact us for concurrence if you subsequently judge that another location
might be more representative of the stormwater flows from your site.

Re:NCS000106
>ar Mr. Pickle,
Thank you for taking the time to come by the mill at Roanoke Rapids, June 9, 2009 with Matt fleahman to
review our permitted stormwater discharges. Neal Davis and I appreciate the opportunity to discuss these sampling
and operational challenges with you. Your experience was most helpful.

It is our understanding, that based on your visit, we are in agreement that the area called "Storeroom" may be
placed under representative outfall status such that we would conduct visual observations twice annually, This portion
of the mill does not store any process material and has minimal traffic. We request this permit modification.
With regard to the sample location at the "Tent," we request relocation of the current monitoring point. The
suggested location is downstream from the current site to just above the City of Roanoke Rapids first inflow to the
ditch.
Sincerely,
Mary Lee Ransmeier

during the three (3) previous years and any corrective actions taken to mitigate
spill impacts,
(e) Certification that the stormwater outfalls have been evaluated for the presence of
non-stormwater discharges. The certification statement will be signed in
accordance with the requirements found in Part III, Standard Conditions, Section
B, Paragraph S. The permittee shall re -certify annually that the stormwater
cattails have been evaluated for the presence of non-stormwater discharges.
2. stormwater Management Plan, The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, 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 stormwater. 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, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff 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 Superfland 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 directly 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), and any stormwater that accumulates
in the containment area shall be at a minimum visually observed for color, foam,
outf'all 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.

through monitoring of stormwater discharges$ The BMP Summary shall include it
Gvrilten record of the specific rationale for installation and implementation of the
selected site 13MPs. The 13NIP Summary shall be reviewed and updated annually.
Spill Prevention and Response Plan. The Spill Prevention and Response an (SPRP)
shad incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing
the SPRP shall be identified in a written list incorporated into the SPRY 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 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, 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 }Iousekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all stormwater control systems, 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.
Inspection of material handling areas and regular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall be recorded in writing and maintained
in the SPPP.
5. 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. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by the signature of each employee trained.
6. Responsible Party. The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the Stormwater

Permit No. N('So()01()6
i'ollution Prevention Plan shall be reviewed and updated on an annual basis. The annual
update shall include an updated list of significant spills or leaks of pollutants for the
previous three years, or the notation that no spills have occurred. The annual update shall
include re -certification that the stormwater outfalis have been evaluated for the presence
of non-stormwater discharges. Each annual update shall include a re-evaluation of the
effectiveness of the BMPs listed in the BMP Summary of the Stormwater Management
Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
submit a time schedule to the Director for modifying the Plan to meet minimum
requirements, The permittee shall provide certification in writing (in accordance with
Part 111, Standard Conditions, Section B, Paragraph S) to the Director that the changes
have been made.

SECTION Rt ANALYTICAL NIOiNITORING REQUIREN11414to
Analytical monitoring of stormwater discharges shall be performed as specified in Table t. All
analytical nwnitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term
of the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours,

Fiber Filtration Tubes (FFTs)
A Fiber Filtration Tube (FFT) is an engineered composite of Thermally Refined"" wood fibers,
man-made fibers and performance -enhancing polymers encased within cylindrical tubes
composed of a heavy-duty, knitted, high density polyethylene mesh.
Fiber Filtration 9-ubes come in
rs and lengths for a variety of applications;
------- --- - -
Sediment Retention Device (SRD) When utilized as a SDR, the Fiber Filtration Tubes allows
water to flow freely through its matrix, providing three-dimensional fltration of soil particles and
facilitating the release of flocculants to coagulate and aggregate suspended soil particles. The
resulting combination of Flow, Flocculation and Filtration separates Fiber Filtration Tubes
from other fiber rolls and wattles.
Slope Interruption Device (SID) When utilized as a SID, Fiber Filtration Tubes absorb
concentrated flow and distribute it more evenly downstream of the tube.

Polyacrylamide (PAM)
PAM polymers interact predominantly with the clay and fine
fractions of soils.
PAM creates an electrochemical reaction that induces these
fine soil particles to cluster together.
IC i Y
Clustered particles are more resistant to erosive forces and
aid in deposition.
Applied Polymer Systam's (APS) line of soil specific tailored polyacrylamide co -polymer powders, emulsions and Floc Logs
that reduce initial erosion and removes fine particles from storm water run off. APS products are particularly effective in
treating troublesome colloidal clays which tend to stay in solution and cause cloudy discharges.
APS Silistop powder can be applied dry by a number
of different methods, either by itself or cut with dry
sand,
depending on
equipment and project considerations. APS Sillstop
powder and emulsion
can be hydraulically applied
along
with seed,
mulch and fertilizer. This proactive application will "cluster'
soil particles at
the surface and prevent erosion.

While they can he used alone, APS
Floc Logs generally represent the
second phase of a "belt and suspender" approach to

are tailored to specific soils and should not be used
prior to site specific telling.

13.1. CYeneral Cllarac(erisCics and Purpose
Any natural vegetated area, from grassy meadow to small forest, may Ue adapted for
seas a filter strip. Filter strips are often referred to as vegetated filters. Man-made
filter strips (on graded, prepared, an(l planted areas) can be just as effective as some
natural areas. Many types of plants or natural vegetation can be used in filter strips
ranging from close -growing grasses to shrubs and trees. However, the vegetation must
have dense foliage and a thick root mat to be effective, Filter strips are designed to
accept runoff from overland sheet flow from upgradient development. The filter strips
trap sediment and sediment -bound pollutants. Because they disconnect impervious
surfaces from storm sewers and lined channels, filter strips reduce effective
mperviousness and help reduce peak discharge rates by increasing travel times and by
increasing abstractions from the total flow. Figure "13-1 illustrates the basic elements of
a filter strip.
Filter ships may be used to treat runoff Prom highways, roofs, parking areas, and in
generalI Ueiween upgradient development and receiving waters, frequently in
residential areas, or where the development density is low. Filter strips can also be used
as prehealmeut for infiltration BMPs such as bioretention and infiltration trenches. They
are also part of the outer zone of riparian stream buffers. Additionally, for projects
under North Carolina's State Stormwater Management Program rules, a filter strip may
Ue a required companion BMP for the discharge from other BMPs, such as wet detention
basins and infiltration BMPs.
A level spreader is required with every filter ship, unless permanent, sustained sheet

NCDBNR SIonmvater 13M1 Mantud Chapter 1%evised 09-20-07
V01101M Control C11ci11 UMIS
Filter strips do not have any water storage component, so they do not provide any active
volume control. Filter strips do provide passive volume control capabilities through a
couple of mechanisms. First, they provide pervious surface to reduce the total runoff
volume to be controlled. Second, if designed in such a way, they can increase the time of
concentration and therefore reduce the peak discharge rate.
Filter strips can provide some runoff peak attenuation, largely by increasing tine time of
concentration in a subbasin, and by creating disconnected imperviousness. The
effectiveness of filter strips in reducing runoff peak rates can be improved by: siting them
over the most permeable soils thereby reducing the MRCS curve number (CN) associate((
with the filter strip, placing them so as to receive runoff from impervious surfaces, and
interconnecting them with grassed swalcs or bioretention areas to increase the time of
concentration.
1.3.3. Design
13.3.1. Siting Issues
Pilter strips perform well. in all areas of North Carolina where dense, vegetative l;rowth
can be established. High dune areas of coastal counties are too dry to support dense
vegetative cover and are not appropriate for filter strips. Also, slopes must be in the
appropriate range: less than 5 percent slope is preferable; in no cases, may slope exceed
15 percent.
7.3.3.2. Contributing Drainage Basin
Where filter strips receive the runoff directly from the drainage basin, they should be
limited to relatively small tributary areas. Relevant considerations include the ultimate
imperviousness of the drainage basin, the amount of flow delivered to the filter strip, the
permeability and erodibility of the underlying soil, the type and condition of vegetation
present in the filter strip, the presence or absence of small rills, and the slope of the filter
strip.
Pilter strips can be used for larger areas if they are used in series, or interspersed
between impervious surfaces (for example, by incorporating filter strips between
parking lanes). The design of filter strips in larger areas should be supported by
calculations that acknowledge and address the potential vulnerabilities associated with
such installations.
13.3,3. Sheet flow
If flora is allowed to concentrate before it reaches the filirr strip, or as it crosses over the
Filter strip, the rates at which pollutants are removed will be reduced significantly,
gullies will develop, and the filter strip will be ineffective. To achieve the benefits of
reduced runoff rates, pollutant removal, and increased infiltration, it is essential that the
flow be transitioned to sheet flow through the use of a Level spreader. A level spreader
piltcr Strip 13-9 1u1y 2(H)7

NCDENR Sloruuvaler B\41' Manual
Revised 09-28-07
is required for all filter strips unless it caul be proven that the inflow wilt be evenly
distributed sheetftow without the use of a level spreader.
13.3441 Length and Width for Pollutant Removal Credit
The top edge of the filter strip should follow an elevation contour. If a section of the top
edge of the strip dips below the contour, runoff eventually may forma channel at the
]ow spot. Under some site topography and grading circumstances, runoff may travel
along the top of the filter strip rather than through it. Berns may be placed at intervals
perpendicular to the top edge of the strip to prevent runoff from bypassing any portion
of the filter strip.
The length (perpendicular to flow) of a filter strip is based on the same criteria as the
length of a level spreader presented in Chapter 8 Level Spreaders. 'Fite length of the
filter strip mast be between it minf stun of 13 feet and a maximum of 130 feet. The
length must be. calculated as follows.
— Frn• vegetation characterized as
grass or
thick ground cover: 7,3
feet o£ length
per I cis of flow on slopes 0-8 %.
— For vegetation characterized as
forested:
65 feet of length per 1
cfs of flow for
slopes front 0-6 % .
— If the forest vegetation is 100-150 feet in
width, then the length
call be reduced
to 50 feet of filter strip per 7, cis
of flow.
— If the forest vegetation is more
than 150
feet in width, then the
length can be
reduced to 40 feet of filter strip
per I cis
of flow.
Forested filter strips must be signifirmtly wider than those with grass or thick ground
cover, due to the forest's greater susceptibility to erosion.
IE the Eiltc:r strip has discrete
sections with grass or
thick ground cover in one part and
forest vegetation in another, then the length should be determined
weighted average of the lengths required for each vegetation type.
by calculating the
For example, if a
fitter strip that has 20 feet of
the width maintained
as grass and 30
feet of the width is
existing forested vegetation,
the appropriate filter
strip length will
be:
(20/50) x (13 ft/lets) { (30/50) x (65 ft/1 cfs) = 44.2 or 44 feet per cfs of flow
The width (parallel to flow) of a filter strip steal( in all cases be a minimum of 50 feel.
13,3.5. Length and Width for Compliance with the Slate Stormwater Program
In most circumstances under the State Stormwater Management Program rules at NCAC
15A 2H.1000, a filter strip is a required additional component o(a control system based
on another BMP. For example, the discharge of a wet detention basin must flow
trough a companion vegetated filter strip for ponds designed to treat 85 % TSS. Ponds
designed to treat 90 % do not require a level spreader/filter strip. No specific numerical
value of pollutant removal is assigned for the filter strip alone, but the filter strip must

stabilized. In most instances, a forebay is required prior to the level spreader to capture
the sediment prior to entering the filter strip. For filter strips downstream of wet
detention basins and infiltration devices, a forebay may not be required if sediment
capture is effectively accomplished by the upstream BMP.
13.3.7. Slopes and Velocities
Ut general, filter strips are most effective on sites v,�ith mild slopes. Regulatory program
limitations on maximum slopes are identified in section 13.3.4 above.
A key design objective is that the design overland flow velocity must benon-erosive.
Overland flow velocity may be. managed by the following methods: maintaining low
slopes and uniformly sloping grades, limiting.flo"r volumes to appropriate levels,
providing good flow distribution, repairing erosion features immediately upon
discovery, and maintaining a dense and healthy vegetative cover. Non -erosive velocity
is also dependent on soil type, and the designer must consider soil type in evaluating
design velocities, Typical non -erosive velocities range from 4 fps if the vegetation is
dense grass or undergrowth, and less than 2 fps if the filter strip is wooded.
13.3.8. Plant and Landscape Requirements
1'o realize file benefiCs of filter strips, it is essential to maintain a dense, vigorous stand of
vegetation. For forest or shrab vegetation, it is recommended that the vegetation
generally be deep-rooted, have well -branched top growth, and resistant to damage from
either saturation or drought Vegetation on filter strips receiving street and parking lot
runoff must be resistant to deicing chemicals, salts, and heavy metals (tall fescue has
been shown to be quite resistant to road salts).
Well -drained soils are preferred, however, with propersoil preparation and selection of
appropriate plant species, filter sides can be established successfully on poorly drained
soils,
A natural forested area provides good long' -term removal of pollutants and priority
should be given to preventing the unnecessary removal of trees. Native vegetation often
takes longer to establish than turf grass; however, this can be. managed by planting the
native vegetation early and allowing it to become properly established prior to allowing
stormwater onto the BMP.
A grading and vegetation plan must be prepared by an appropriately licensed design
professional for all filter strips,

13.4 Construction
Revised 09-28-07
Accurate grading is necessary to develop sheet flow Through the fitter strip, filter strip
soil compaction by egtliputent or vehicles during construction should be minimized. Over
time, the permeability of compacted soil can be restored through the action of vegetation
root systems. However, the restoration takes 5 to 10 years and the vegetation may be
difficult to establish without a good layer of topsoil.
13.5 Mainfienance
13.5.1. Comunon Maintenance Issues
During the fitstone or two years after ca�shuction, filter strips and revel spreaders
should be inspected for proper distribution of flows and signs of erosion during and
after major storm events. After the first one or two years, the strip may be inspected
annually or biannually. If evidence of erosion exists, the eroded areas should be filled in
and reseeded, The cause of the erosion should then be determined and, if possible,
eliminated.
Filter strips that are not maintained properly may qurcldy become nonfw�ctional
(Schueler et al.,1992). Maintenance involves routine activities such as mowing,
trimming, and replanting when necessary. Strips that receive excessive sediment may
require periodic regrading and reseeding of their upslope edge because deposited
sediment can kill grass and change the elevation of the edge such that the stornmvaEer no
longer flows through the strip in thin sheets. Maintenance requirements are as follows:
13.5.2. Svnple Inspection and Maintenance Provisions
Important maintenance procedures:
— Iuuzutdiately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency, Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as fall as'12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
Once a year, the soil will be aerated if necessary.
Once a year, soil pl-I will be tested and lime will be added if necessary.
After the filter ship is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).

General Characteristics and Purpose
Grassed swales are typically long open drainage channels into„rated into the
surrounding development or landscape that are. lined with grass or other vegetation.
They are often used in residential and commercial developments as well as along
highway medians as alternatives or enhancements to conventional storm sewers (see:
Figure 14-1). Swales are suitable for many types of development, but are most practical
for campus -type developments and single-family residential sites.
Figure '14-1
Grassed Swale in Residential Area, Pembroloe Woods Subdivision in Rnrtnittsburg, MD
(Courtesy of Mike Clar, ficosite, Inc., Columbia, MD)
Swales remove pollutants from su>rmwater by biofihratiot, settling, and infiltration.
(}rased swales filter pollutants as suxmwalcr runoff moves through the leaves and roots
of the }crass. 13y reducing (low velocities and increasing a site's tittle of concenuation,
grassed swales contribute to reCluciug runollpeaks. Grassed swales that are Clesigned with
check clams or incorporate depression storage promote filliltation and can help contribute
o satisfying a site runoff caphu'e/storage rMuircntcut.
'he
effectiveness of a Swale in both reducing Che flow rates and volume of runoff, and
renxrvint*, Pollutants, is a function of thr size and composition of the drainage area, Che
slope and cross section of 11w channel, the permeability of the soil, the density and type
If vegetation in the swales, and the swale dimensions. Broad swales on flat slopes with
dense vegetation are the most effmctive. I2eutoval efficiencies are Itil;hest for sedintent-
bound pollutants.

consider using Wrf reinforcement, energy dissipaters, or lined channel segnx�nls.
The methodology for channel lines design is presented in the DIiNR Erasion and tirdinu•nf

1'hc flow depth of the design event should be evaluated using Manning's equation for
lie swale type used (parabolic, trapezoidal, or V-shaped), 'file design requirement is
chat the swales convey the design discharge while maintaining a 0.5-foot ficeboard and
vilhout exceeding the maximum permissible velocity,
if driveways or roads cross the Swale, the capacity of the culvert crossing the road or
driveway may determine [tie depth of flow for the design event. In these instances, the
culverts should be checked to establish that the backwater elevation does not exceed the
tanks of the swale. If the culvert discharges to it miIli III Urn taiIwater condition, the exit'
vclocity for the culverishoald be evaluated for design conditions. rf the maximum
permissible ve,locity is exceeded at the culvert outlet, ripiap or another measure to
preventscom must be used.
1�I.2.5. 1'lanf and T.andscape IZcquirements
l.:uuiscape design is based on specific Sim, soils, and hydric conditions along the
channel. A dense grass cover is the best vegetation to maximize the performance of a
gVass swale.
Standard hu'f grasses may be used if a lawn appearance is desired. •rile turf grasses
nclude standard IIIiXLnrefi stub as those recommended in the DENR Erosion and
Sediment Control plaguing and Design Manual and the recommended vegetation tables in
Section 6 of this document. The recommendation is to use taller growing l;t'asses to
mprove the filtering capability of the Swale. Biuegrass should be avoided for areas
where salt loading is high.
Soil with a high infiltration rate is typically nuxtap}nopriate Eor grassed swate 13iMPs.
"Topsoil should be suitable for hcal[Ity ttn'I };rowth. Where the eaistin}; soil is unsaitable
for growth (such as clayey or rocky soil), applying about "12 inches of loamy or sandy
soil is beneficial
'12.2.6. Ponding and Infill ration
Ponding can be beneficial if intended and accepted, or it can be a negative it unintended.
If unintended and not designed got', extended periocis of standing, water may result in
nuisance conditions and create complaints from residents. Mosquitoes are typically the
biggest concern, however, they should generally not be it problem because of the
irequcnt flushing of the ponded water, and if wetland vegetation develops, mosquito
preclatoi:s such as other insects and birds often mitigate the mosquito problem. If
wetland vegelafian and stilt c[ill g wafer are pct:sistent conccras, these problems can be
educed by maintaining more uniform, sleeper slopes in the swale invert or by installing
underdrains.
If temporary retention of small anxxmis of teahlr is desired for enhanced Crea toentof
the sha'iitwnler anii ecological and visual diversity, there arc many ways to achieve that
goal. 'The paragraphs below discuss several methods for retaining water or otherwise

nuxiifying the typical swale hydrology. The retained waiter wilt infiltrate, be lost
througfi evapotranspiration, or slowly re(easeci clownstreani. It should be noted that the
maximum allowable poncling time within a channel is 48 Rows and an underdrain
system mist be provided if that requirement cannot be met.
Check Dams
A check deem is constructed of earth, slone, or timber 3 to 6 inches high to retain runoff
from routine events. A weep hole may be added to enable the area behind an earthen or
timber clam to drain slowly. However, the weep hole may be subject to clogging. Shorter
check dams can act as level spreaders to help distribute the flow along theswale-•'.s cross
section. See Figure'111-6.
I fewded Drojr Inlets
A chop inlet call be used When a combined system of smiles and storm sewers is being
used. The swales would serve as the collector System, and the inlet into the main storm
sewer system well ill be elevated slightly to retain runoff from routine events.'Che height
of elevation would depend on the soil, the slope of tine "wale, and the tolerance for
pending. Weiland vegetation may develop in the ponded areas if the underlying soils
are poorly chained.
autterl Crdcurls
vated culverts are used for the same purpose as check dams and elevated chop inlets,
to retain rwioff front routine events. As with Movated drop inlets, wetland vegetation
may develop in the ponded areas if the underlying Soils are poorly drained.
I )epressiou slorrrge
Small depressions along the bottom oP the Swale will trap and store stormwalm for later
ufiltiation into the soils. These depressions will also likely aeeUmnlalC sediment ai a
quicker pace than ocher parrs of tine swale, and will also probably develop wetland
vcgctation.

14.3. Conseruction
Co nutximizo lhr, inlilhalion capacity of the swale, compaction o[ the soil underlying the
Swale should be avoided. For example, cyuiputent for excavating or grading should
operate from the side of the swale instead of the bottom of the swale.
Before vegetation is established in a Swale, the Swale is particularly vulnerable to scour
and erosion.'1'hcre(are, protecting [he seedbed with a temporary erosion -resistant lining;,
such as a geosynfhetic, liberglasS roving, 01 other suitable erosion controls is generally
nctcessary. Nlost vendors will furnish information about the Manning's Coef(icient, n,
and will also specify the maximum permissible velocity of allowabte unit tractive force
also referred to as tile "tractive. stress") for the lining material. Swales should be
constructed and vegrtlaled early in the construction schedule, preferably before area
grading and paving increase the rate of runoff.

NCDF.NR Stormwater BMP Manual
Revised: 06 08-09
Temporary erosion -resistant channel linings should be used to stabilize the swate until
lie vegetation becomes established.'rile venclor's instructions for installing channel
[finings should he followed. If velocities will be high, designers should consider sodding
the Swale or divetrting runoff until vegetation is established.
14.4. Maintenance
14.4.:L. Common Maintenance Issues
Maintenance of grassed swates involves grooming Hte vegetation and occasionally
emoving trash. If native vegetation is used instead of turf, vegetation has to be moeved
only seasonally to retard the growth of woody vegetation. Routine mowing is required if
turf grasses are used.'1'he recommendation is that grass be cut no lower than 5 inches. In
adcliLion, the grass should he allowed to grow to the maximum height consistent Willi
the species and aesthetic requirements. Swales populated with wetland vegetation or
other low -maintenance ground cover do not require mowing of the channel -The
frequency of trash removal depends on the location and athactiveness of the swaleas a
disposat Slle,

however, if excessive siltation occurs, the,50dintcrnt must be removed periodically (no
less than On(le annually). Sediment that a(:cuuudates in Lhe Swale may be prone to
resuspeusion during large storm events and can kill the grass. Sediment Should be
removed when it reaches it depth of 4 inches or when it covers the £,lass.
AdcLitional annual maintenance activities are as Eollotvs:
— Repair erosion and regradc the Swale to ensw'et that runoff (tows evenly in a
thin sheet through the Swale.
Revegetate the swale as needed to maintain a dense growth.

Riparian buffers are natural vegetated areas along a strenmbank (see Figure 15-1.}. They
improve riparian habitat Uy:
Providing food and cover for wildlife and aquatic organisms,
Stabilizing stream banks,
- Filtering pollutants from stormwater,
— Attenuating the rate of runoff into streams, and
Increasing infiltration and recharge to groundwater and surface water bodies.

15.2. Meeting tZegixlatory RegixiLernents
To receive the pollutant removal rates listed in the front of this Section, the restored
riparian uffer must meet all of the major design requirements listed in the beginning of
this Section. If restored riparian buffer will not meet the regulatory requirements of the
site by itself, other BMPs can be used in conjunction to provide enhanced pollution
removal rates or volume control capabilities,

A properly sited, designed, constructed and maini��ined restored riparian buffers has the
following associated pollutant removal rates:
60% Total Suspended Solids
30% •Total Nitrogen
— 35% •Total Phospliorus
Construction of a restored riparian buffer also passively ]owers nutrient loading since it
is counted as pervious surface when calculating nuhienC loading.
Vnhuue Control CaIci+lotions
A restored riparian buffer typically does not provide any active volume caphue or peak
fIOW attenuation. A restored riparian buffer provides some passive volume control
capabilities by providing pervious surface and therefore reducing the total runoff
volume to be controlled.

All of flee following siting requirements must be met in order for a restorcci riparian
Duffer to be constructed and receive the stated pollutant removal efficiencies:
1. They may only Ue constructed directly adjacent to a perennial or intermiftent
surface water. A perennial or internuttent surface water is considered to be
present if the feature is approximately shown on either the most recent version of
Elie Soil Survey Map prepared by the Natural Resources Conservation Service of
the United States Department of Agriculture or the most recent version of the
1:24,000 scale (7.5 minute) quadrangle topographic maps prepared by the United
States Geologic Survey (USGS).
2. "1'he existing riparian Duffer must Ue "impaired." An "impaired" riparian Duffer
includes: fields and pastures thathave been actively used within the lnA3 years,
and wooded buffers that have been critover within the last 5 years or where the
woody vegetation is absent or sparse (less than 100 stems per acre that are
greater than 5 inches diameter at breast ))eight).
3. 'I`he slope of the riparian buffer must not Dc greater than 6 percent.
4. 1'he restored riparian Duffer must De used only when the flow to the level
spreader is less than 3 cfs. This flow could De coming directly from the drainage
area during the one inch per hour storm or the drawdown flow from another
BMP.
All restored riparian Duffers must Ue placed in permanent easement so it will not later be
decreased or removed from the site.
15.3.2. Length and Width
The restored riparian Duffer must a total of 50 feet in width and it must be composed of
a zone of grass (20 feet wide) and a zone of forest vegetation (30 feet wide) as described
in Section 15.3.3 below.
he
length of Ievel spreader is determined by calculating the weighted average of the
lengths required for each vegetation type as shown below.
(20/50} x (13 ft/lcfs) + (30/50) x (65 Pt/1 cfs) = 44.2 or 44 feet per cfs of flow
Since the maximum Iengeh of a level spreader is 130 feet, this means that each restored
riparian buffer is able to treat 3 cfs of flow. 1'he level spreader may De designed to treat
the one inch per hour storm with a bypass channel or the 10-year, 24-h0ur storm without
a bypass channel. See chapter 8 for information about properly designing level

waterbodies) and extends landward a distance of 30 feet perpendicular to the stream.
Zone 1 consists primarily of wooded vegetation that may not be disturbed except for
removal of nuisance vegetation (see Section 15.3.6). Zone 2 extends a minimum of 20
additional feet beyond Zone 1. Zone 2 is 'intended to diffuse and infilhate runoff and
filtering of pollutants. It may be grassed, and other vegetation and periodic
maintenance are allowed.
