EXECUTIVE SUMMARY
This Stormwater Pollution Prevention Plan (SPPP) was prepared for the Westlake Royal
Building Products (WRBP) Plant 2 (Facility), located in Salisbury, Rowan County, North
Carolina, to comply with the North Carolina National Pollutant Discharge Elimination
System (NPDES) General Stormwater Permit No. NCG050000 (General Permit No.
NCG050000). The General Permit (GP) is administered by the North Carolina
Department of Environment Quality (NCDEQ) and was issued to the Facility in response
to their 2018 Notice of Intent (NOI) to be covered by the GP. The Facility was granted
coverage under NCG050000 through NCG050428 on 6/1/2018.
The intent of the SPPP is to minimize pollution of stormwater runoff from the Facility. The
SPPP specifies the procedures the Facility personnel will follow, the engineering controls
that are or will be implemented to prevent stormwater from comingling with potential
pollutants, or to contain potentially contaminated stormwater.
The GP requires compliance with the SPPP. Items of particular interest for the SPPP
include those listed below.
• A copy of the GP is included as Appendix A. This SPPP has been written to
comply with the requirements of Part II Section A of the General Permit.
• Section 7.0 of this SPPP describes the semi-annual facility inspections and visual
inspections that must be conducted. Please note that the facility inspection differs
from the visual inspection performed at each stormwater outfall. The facility
inspection involves inspecting the facility's stormwater control systems, plant
equipment, and systems. The visual inspections involve collecting stormwater
samples from each outfall, conducting a visual assessment of each sample, and
documenting the observations
• The SPPP is amended whenever there is a change in design, construction,
operation, or maintenance that has a significant effect on the potential for the
discharge of pollutants to surface waters. The SPPP is also amended if the
procedures in the SPPP prove to be ineffective in eliminating or significantly
minimizing pollutants from potential sources.
• This document may be revised frequently. Therefore, document control is necessary
to make sure that changes are incorporated in an effective manner. Each time the
SPPP is amended or updated, the date of the latest revision is included on the cover
page and page number v. If worksheets are updated, the revision number and the
date of the revision are inserted in the upper right hand corner. Worksheets that
are replaced are kept on file as a reference. The SPPP document and all attachments
are maintained at the Facility; unless a copy is specifically requested by a regulatory
agency.

SECTION 1
INTRODUCTION
All facilities covered by the North Carolina Department of Environment Quality's June 1,
2018,National Pollutant Discharge Elimination System (NPDES) General Permit No.
NCG050000 (the General Permit, NCG050000) must prepare and implement a Stormwater
Pollution Prevention Plan (SPPP). The intent of the SPPP is to evaluate potential pollution
sources at the Facility. After the evaluation, the Facility selects and implements appropriate
measures to prevent or control the discharge of pollutants in stormwater runoff.
The stormwater pollution prevention approach focuses on three objectives:
1. To identify sources of pollution potentially affecting the quality of stormwater
discharges associated with industrial activity from the Facility;
2. To describe and outline implementation of practices to minimize and control
pollutants in stormwater discharges associated with industrial activity from the
Facility; and
3. To provide a mechanism for compliance with the terms and conditions of the
General Permit.
The development of a SPPP involves the items listed below.
• Formation of a team of qualified Facility personnel who will participate in
the development, implementation and maintenance of the SPPP;
• Assessment of potential on -site stormwater pollution sources;
• Selection and implementation of appropriate management practices and
controls; and
• Annual evaluation of the SPPP to prevent stormwater pollution and comply
with the terms and conditions of the General Permit.
This SPPP document is a foundation for the Facility's stormwater pollution prevention
program. As conditions and practices at the Facility change to accommodate new methods
of production, storage and material transfer; this document is revised accordingly.
The SPPP describes activities, materials, and physical features of the Facility that may
contribute pollutants to stormwater runoff. The procedures and methods that are used to
minimize these impacts are incorporated into the plan. Worksheets were developed based on
the Environmental Protection Agency's (EPA) guidance document for developing SPPPs
(EPA 833-B-09-002) that were used when creating this document. These worksheets are
located in Appendix B.

SECTION 2
SITE DESCRIPTION
The Facility is situated on approximately 20.57 acres located at 175 Circle M Drive, Rowan
County, Salisbury, North Carolina. The site consists of a 121,582 square foot industrial
building with two loading areas, a parking lot, a recreational canopy, an above ground water
tank, and an outdoor storage area. The industrial building houses offices, a manufacturing
floor, a maintenance area, a flammable storage cabinet, and the paint storage area. The only
indoor industrial activity at the site is the manufacturing of new building composites for
exterior use. Additionally storage of in -process and finished product material occur at the
site. Saw dust is a byproduct of the composite manufacturing process. The saw dust is
controlled by two dust collectors, as well as collected by sweeping and floor washing. The
dust collectors are located on the southeast side of the industrial building. All saw dust is
hauled off -site.
Loading areas are located to the north and south of the building. The parking lot is located
on the west side of the building at the entrance to the industrial building. In -process and
finished product is stored in the designated storage area along the southern boundry of the
property.
The site is developed with an asphalt and concrete groundcover to include the buildings,
driveways, canopies, water tank, loading, and parking areas. The outdoor product storage
area consists of crusher run that is considered partially impervious. The remaining area
consists of undeveloped and grassy areas. Approximately 48% of the Facility is impervious
to stormwater.
The site is secured by perimeter fencing. The Facility's entrance gate is locked during non -
operating hours. The site is bound by Cedar Springs Road to the west, Circle M Drive to
the north, and wooded areas to the south and east. Industrial sites are located to the north
and east while residential and undeveloped sites are located to the west and south.
Operations located withing the belt production room are covered under a Spill Prevention
Control and Countermeasures (SPCC)Plan. These operations and liquids include the
polyol totes and MDi totes. Vehicle maintenance is performed on -site by a Westlake
Royal Building Products approved sub -contractor.
The location of the Facility and the topographic, hydrologic and cultural features of the
surrounding area are shown on Figure 1 in Appendix C. Figure 1 was developed from the
United States Geological Survey (USGS)Rowan Mills, Salisbury, China Grove & Rockwell
Quadrangle, North Carolina, 7.5 Minute Series (Topographic) map, dated 2019. The center
of the Facility is located at approximately 35° 37' 54.1" north latitude and 80' 31' 49.8"
west longitude. The Facility gently slopes to the northwest and is at an approximate
elevation of 770feet above mean sea level (MSL). The site layout, stormwater flow, outfalls,
receiving stream, industrial activities, and best management practices (BMPs) are depicted
in Figures 2 and 3 of Appendix C.

December 2021 Stormwater Pollution Prevention Plan

2.1 Identification of Outfalls
The stormwater from the Facility will either be absorbed by the pervious ground cover, or
be ultimately discharged to the Grants Creek. Stormwater drainage from the site flows into
drop inlets and ditches which discharge off -site at the following outfalls:
• Outfall # 1 — Site entrance on the west of the property boundary — Impervious
runoff is comprised of the finished product and in -process graveled storage area to the
southeast and some road surfaces. The Outfall receives diffused flow from the
grassy/vegetated area to the southwest and the grassy area south of the water tank.
The total drainage area is an estimated 7.91 acres with 44% of that being impervious.
The outfall moves north along Cedar Springs Road to an unnamed tributary then
flowing into Grants Creek.
Outfall #2 — Undeveloped land to the west of the industrial building, 30 feet west
of the parking lot — Impervious runoff is comprised of the parking lot, southern
loading area, southern half of the industrial building roof, and majority of road
surfaces. All impervious flow is captured by the site's stormwater conveyance system
via drop inlets at various points along the road surfaces and southern loading area.
The southern loading area is slopped towards a 265 foot grate inlet that contributes to
Outfall #2. The outfall receives diffused flow from the undeveloped area west of the
industrial building and the grassy area north of the water tank. The total drainage area
is an estimated 9.76 acres with 46% of that being impervious. The outfall moves west
in the undeveloped portion of the site until it adjoins the northern ditch flow along
Cedar Springs Road to an unnamed tributary which flows into Grants Creek.
Outfall #3 — Loading area northwest of the industrial building — Impervious
runoff is comprised of the northwest corner of the industrial building roof and loading
area. The outfall receives diffused flow from the grassy area to the northwest of the
industrial building. The total drainage area is an estimated 0.48 acres with 68% of that
being impervious. The outfall moves west along Circle M Drive to an unnamed
tributary which flows into Grants Creek.
Outfall #4 — Grassy area north of the industrial building — Impervious runoff is
comprised of the majority of the northern half of the industrial building roof. The
outfall receives diffused flow from the grassy area to the north and west of the
industrial building. The total drainage area is an estimated 1.77 acres with 66% of that
being impervious. The outfall moves west along Circle M Drive to an unnamed
tributary which flows into Grants Creek.

• Stormwater conveyance system/drop inlets;
• Stormwater drainage patterns; and
• Potential pollutant sources.
2.2 Site Operations
Boral Building Products — BCI was purchased by Westlake Chemical in October 2021 and
rebranded as Westlake Royal Building Products — TruExterior. The TruExterior facilty
began operations at Plant 2 in the Spring of 2015. Prior to the TruExterior facility, the
Facility was owned by Lerner Shoes, Inc and operated as a Rack Room Shoes warehouse.
Westlake Royal Building Products — TruExterior operates under the SIC Code 3086 - Plastic
Foam Products. Operations are generally three (3) shifts per day, 24 hours a day, and five (5)
days per week. The Facility operates on Saturday and Sunday if production requires it.
When operating at full capacity, the Facility will employ approximately 50 people including
production, maintenance, management, and administration personnel.
The primary manufacturing process starts with 8-20 foot long boards brought in as in -process
product. The boards are fed to Plant 2's "finishing process" on a conveyor. The boards are
cut to the appropriate product shape on a moulder, sanded to the desired thickness, painted
with a water based paint, and dried in a NIR oven. The boards are stacked on pallets where
quality control is confirmed. Quality control ensures proper dimensions, angles, paint
adherence, and appearance. The pallets are covered, strapped, labeled, and placed in the
product storage area. The boards are loaded on to flatbed trucks for transport to the
customers.
A secondary semi -manual manufacturing process includes: a moulder, sander, painter and
rip saw for making smaller quantities of certain products.
In -process and finished product materials are shipped to the site for finishing or storage.
Water based paints are the only raw materials for finishing of composites that are received at
the plant. Containment is provided in the loading area and used during the delivery of the
water based paints. Additional gas, oils, paints, etc. are stored inside in the containment area,
or the maintenance area.
Used oil is not stored on -site. The Facility has several propane -powered forklifts. The
maintenance of the forklifts is performed on -site by a Westlake Royal Building Products
approved sub- contractor. The contractor removes the oil from the Facility and properly
disposes it.
The facility has one 400,000 gallon above ground storage tank (AST) for water used only for
the Facility's fire suppression system. Worksheet 1 of Appendix B details the above ground
storage water tank on -site.
Sage Environmental Consulting, L.P. 2-3 Westlake Royal Building Producs - TruExterior —Plant 2
December 2021 Stormwater Pollution Prevention Plan

The primary solid waste generated by the site's manufacturing process. The waste includes
discarded/rejected finished material and sawdust resulting from manufacturing process.
Small amounts of waste associated with minimal daily office and production activities are
generated as solid waste and are disposed of in trash containers located at the site. Waste
from production areas could include items such as cardboard, floor sweepings, protective
wrapping, and banding. The site disposes of its general solid waste through a contracted solid
waste company. The contractor hauls the solid waste to the Rowan County Solid Waste Landfill
at least twice a week.
In addition to TruExterior's manufacturing activities, the Westlake Royal Building Products
R&D support group also performs some activities in the main production building. This
includes making and evaluating potential new TruExterior products. The primary wastes
generated are similar to those generated by TruExterior, but involve much smaller quantities.
These materials (mainly similar saw dust, cardboard, floor sweepings, wrapping, banding,
lunchroom material, etc.) are disposed of with the TruExterior waste.

SECTION 3
INVENTORY OF SIGNIFICANT AND EXPOSED
MATERIALS
To assess possible contamination of stormwater as it exits the facility as runoff and through
Outfalls, an inventory of materials and operational management practices was compiled.
The evaluation identified which materials or practices may affect the quality of
stormwater runoff. The types of Facility materials handled, stored or processed, and the
general management practices that may affect runoff are included in this inventory.
"Significant materials" are defined in the General Permit No. NCG050000 as:
• Raw materials;
• Fuels;
• Solvents, detergents, and plastic pellets;
• Finished materials;
• Hazardous substances;
• Section 313 of SARA Title III chemicals;
• Fertilizers and pesticides; and
• Waste products.
These categories of significant materials include potential stormwater pollutants such as
sawdust, oils, paints, etc. that can impact off -site aquatic ecosystems. An inventory of the
Facility's significant materials that have a potential to contribute pollutants to stormwater
runoff is included in Worksheets 1 and 3 of Appendix B. While the Facility does receive,
store, use and ship materials that are considered potential stormwater pollutants, the
Facility is generally constructed and managed to minimize the contact with stormwater.

December 2021 Stormwater Pollution Prevention Plan

SECTION 4
RISK IDENTIFICATION AND SUMMARY OF
POTENTIAL POLLUTANT SOURCES
Activities, materials, and physical features at the Facility with the potential for contributing
significant pollutants to stormwater were evaluated. The potential stormwater pollutant
sources are summarized on Worksheet 3 in Appendix B. Existing control and management
measures are discussed further in Section 6.0. The Facility activity evaluations presented
below describe potential pollutant sources and the risk that they pose for causing stormwater
contamination.
4.1 Material Delivery, Loading and Unloading
Raw materials, in -process products, finished products and supplies are delivered to the
Facility by truck. In addition, finished product exits the site by truck. The site's only raw
materials are water based paints. The southern loading area is graded towards the inline
grate in the center and collected by the conveyance system to Outfall #2. The northern
loading area is not expected to be used for loading or unloading water based paints.
A spill in the southern loading area of the Facility would flow to the inline grate where it
would be dyked in the conveyance system and contained. A Westlake Royal Building
Products approved sub -contractor would then properly dispose of the spilled material. Spill
supplies are located inside the building in order to respond to any material spill that escapes
containments or hydraulic oil that could leak from delivery trucks.
The potential for stormwater to come in contact with the water based paints and supplies
during truck loading and unloading is minimal.
4.2 Indoor Storage Activities
Storage of the water based paints will be in the facility in a dyked area designed for
secondary containment. Any spillage of water based paints in the containment area will be
cleaned by Westlake Royal Building Products personnel and then properly disposed of
according to state and federal regulations.
4.3 Outdoor Storage Activities
Outside storage consists of in -process and finished product material. All material stored
outside will be wrapped in plastic to ensure minimal exposure to stormwater.
Outdoor vehicles and vehicle maintenance account for the reminder of oil related activities at
the site which have the potential to contaminate the Facility's stormwater. Maintenance on
forklifts is performed on -site by a Westlake Royal Building Products approved sub-
contractor. Vehicle washing does not take place on -site.
Sage Environmental Consulting, L.P. 4-1 lVestlake Royal Building Producs - 7ruE.xterior — Plant 2
December 2021 Stormwater Pollution Prevention Plan

4.4 Outdoor Process Area Activities
No outdoor manufacturing activities are performed at the facility.
4.5 Significant Dust or Particulate Generating Processes
Saw dust is a byproduct of the composite manufacturing process. The saw dust is
controlled by two dust collectors, regular sweeping, and floor washing. The dust collectors
are located outdoors adjacent to the southeast side of the industrial building. The dust is
hauled off -site by a Westlake Royal Building Products approved sub -contractor. The dust
collectors utilize auger technology to ensure no dust waste comes in contact with the
atmosphere when being transfered to two dumpsters that are used to haul off -site.
4.6 Waste Disposal Facilities
Waste generated at the Facility primarily consists of discarded finished material and sawdust
resulting from finishing process. In addition to the two dumpsters mentioned above for saw
dust, general office waste that includes cardboard, paper, plastic, etc. is discarded as solid
waste is collected in two large dumpsters located on the southeast and northwest corners
of the building. A hauler than transports the waste from the four dumpsters to the
Rowan County Solid Waste Landfill twice a week.
The Facility is evaluating ways to minimize waste in the future by re -using sawdust in the
manufacturing process or finding other external uses for the material.

SECTION 5
SIGNIFICANT SPILLS AND LEAKS
As of this revision, December 2021, there have been no significant spills or leaks at the
Westlake Royal Building Products - TruExterior — Plant 2.
In the event of a significant spill and/or leak, the incident should be recorded in this section
as specified below:
If a significant spill or leak of a reportable quantity occurs, this document will be updated
with details of the spill and the cleanup. The spill information will remain part of the SPPP
for at least three years from the date of the significant incident.
Significant spills or leaks include releases in excess of reportable quantities, defined as:
A quantity of a hazardous substance or oil spilled or released within a 24-hour period of time
that exceeds the reportable quantity (RQ) level assigned to that substance under CERCLA or
the Clean Water Act. Hazardous substance levels or quantities are defined in terms of gallons
or pounds. Regulations listing these quantities are contained at 40 CFR 302.4, 40 CFR
117.21 and 40 CFR 110.10. For oil products, a release is defined as harmful quantities that
can cause a sheen or discoloration of surface waters. A release, as used in this statement, is
defined to include any spilling, leaking, pumping, pouring, emitting, emptying, discharging,
injecting, escaping, leaching, dumping, or disposing into the environment that could result in
a contaminated point -source discharge of stormwater. The SDS (Safety Data Sheet) should
be consulted as a guide.
If a significant (reportable) spill or leak occurs, the location will be noted on Table 5.1 on the
following page. Other discharges that may affect stormwater quality will be documented and
maintained with the SPPP records as described in Section 9.0 of this SPPP.

SECTION 6
NON-STORMWATER DISCHARGES
Non-stormwater is any water that is not a direct result of a storm event. Examples inckde
process water, non -contact cooling water, and sanitary wastewater. When non-stormwater
enters a stormwater collection system, it often can become a significant source of pollution
to receiving waters. Under the requirements of General Permit No. NCG050000, most of
these non-stormwater discharges are considered illicit discharges and must either be
eliminated or covered by an individual NPDES permit. Allowable non-stormwater
discharges are found in Part VI of the General Permit.
The Pollution Prevention Team leader will evaluate the Facility for the presence of non-
stormwater discharges to the Outfalls and runoff on an annual basis per the requirements of
the General Permit. The evaluation will be conducted through visual observation during
dry weather and documented on Worksheet 2 in Appendix B.

December 2021 Stormwater Pollution Prevention Plan

SECTION 7
BEST MANAGEMENT PRACTICES
Best Management Practices (BMPs) are measures taken at the Facility to reduce the amount
of pollution entering surface waters. BMPs are broad ranging. BMPs may include processes,
activities or physical structures. BMPs are aimed at preventing spills and controlling
stormwater contamination. They include stressing the importance of management and
employee awareness of potential spill situations, and site activities that could result in
stormwater contamination.
Baseline BMPs are practices that are inexpensive, relatively simple, and are applicable to a
wide variety of industries and activities. Advanced BMPs are more specific and may require
construction or additional equipment where baseline BMPs do not provide adequate control
of stormwater pollution sources.
The following sections describe existing BMPs. Worksheet 4 is included in Appendix B to
summarize these ongoing BMPs.
7.1 Good Housekeeping Measures and Controls
Good housekeeping practices are designed to maintain a clean and orderly work
environment. The types of good housekeeping measures listed below have been implemented
in an effort to prevent pollutants from entering stormwater discharges.
7.1.1 Operation and Maintenance
• Floors and ground surfaces are kept clean;
• Solid waste materials are stored in uncovered dumpsters located to the
northwest and southeast of the building. Solid waste is transferred at
least twice a week to the local landfill by the waste hauler;
• Spillage, especially outside, is promptly contained/controlled,
characterized, and properly disposed of at an approved facility; and
• Equipment, such as drop inlets/conveyance structures, are routinely
inspected to ensure they are maintained in good working order.
7.1.2 Material Storage Practices
• Adequate space is provided to facilitate water based paint transfer and
easy access for inspections;
• Containers, drums and bags of material are stored away from direct traffic
routes to prevent accidental spills; and
• Metal containers are stored on pallets to prevent corrosion.
Sage Environmental Consulting, L.P. 7-1 1,11'estlake Royal Building Producs - TruExterior — Plant 2
December 2021 Stormwater Pollution Prevention Plan

7.1.3 Material Inventory Procedures
• An up-to-date inventory of all materials is maintained; and
• All containers are labeled showing the name of the material, the expiration
date and the health hazards, if applicable.
7.1.4 Employee Participation
Importance of good housekeeping and spill cleanup procedures will be
communicated to employees through safety meetings and briefings at least
annually, but as often as necessary.
7.2 Preventive Maintenance
The Facility's preventative maintenance practices include periodic inspection of equipment
and systems to uncover conditions thatcould cause breakdowns or failures resulting in
discharges of pollutants to surface waters. The following areas will be inspected for
preventative maintenance needs:
• Outside raw material storage area;
• Pole mounted electrical transformer:
• Raw material loading/unloading area; and
• Stormwater drop inlets/conveyance structures.
If it is determined that the loading area is impacting the quality of the site's Stormwater
run- off, the site will immediately begin implementing corrective actions to minimize and
eventually eliminate the potential for stormwater pollution.
Inspection and testing records will be maintained at the Facility and noted in the SPPP when
they are related to stormwater pollution prevention.
7.3 Spill Prevention and Response Plan
This section outlines the steps to be taken to identify and characterize potential spills, to
eliminate or reduce spill potential and to respond if a spill should occur.
7.3.1 Identification of Potential Spill Areas
An inventory of materials is provided on Worksheet 1 of Appendix B, and site
drainage patterns are identified on Figure 2 of Appendix C. The potential for spills
ranges from small leaks during material loading to larger releases from equipment
failure. The areas at the Facility where spills are most likely to occur are listed
below.
• Solid waste handling for transportation off -site;
• Pole mounted electrical transformer; and
• Bulk loading/unloading of water based paints and supplies.
Sage Environmental Consulting, L.P. 7-2 Westlake Royal Building Produes - '1'ruExterior — Plant 2
December 2021 Stormwater Pollution Prevention Plan

7.3.2 Spill Response Procedures and Equipment
In the event of a spill, the area will be immediately isolated. The manager on duty
will be notified. If the spill is less than five (5) gallons, the spill kit will be obtained
from either the loading dock or production area. Trained employees will wear the
proper PPE (Personal Protective Equipment) and clean-up the spill utilizing the
spill kit. Storm and sewer drains will be immediately diked or blocked as needed.
When necessary, materials will be absorbed with an in-house bulk absorbent.
Absorbed or unusable materials will be stored in appropriate containers. These
materials will be properly labeled and stored according to local, state and federal
regulations until proper disposal can be ascertained.
If the spill requires clean-up beyond the capabilities of Facility employees, a
Westlake Royal Building Products approved sub -contractor will be contacted and the
appropriate local agencies will be notified. In the rare case of a chemical fire or other
life threatening situation, Salisbury Fire Department Station No. 6 will be contacted at
[phone].
7.4 Employee Training
Employee training will be conducted to inform employees of the components and goals of
the SPPP. Stormwater pollution prevention will be discussed during Facility safety meetings.
Worksheets 1, 3 and 4 of Appendix B should be distributed to employees to provide an
overview of the stormwater pollutants onsite and the BMPs designed to control them.
Worksheet 5 of Appendix B identifies the trainings topics, schedule and attendees. A brief
description of the topics covered by the training program is presented below:
7.4.1 Spill Prevention and Response

INSPECTIONS
The following section describes the inspections required for the Facility per General Permit
No. NCG050000.
8.1 Facility Inspections
The Facility is required to conduct semi-annual inspections of the site and all stormwater
systems (e.g. stormwater collection/conveyance structures, waste containers, and bulk
material storage and tanks/drums/containers) in accordance with Part II Section A.5.
(Facility Inspections) of the General Permit No. NCG050000. This requirement is in
addition to the required semi-annual visual examination of stormwater samples. The
inspections must occur 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). The facility inspection report form, included in
Appendix D, will document the minimum requirements of the facility inspection program
as specified in General Permit No. NCG050000.
8.2 Semi -Annual Visual Inspections
The Facility is required to collect a stormwater sample from each outfall and conduct a
visual assessment of each of these samples on a semi-annual basis. Representative outfalls
may not be used for these inspections. The semi-annual visual sampling is to be performed
in accordance with Part II - Section C of General Permit No. NCG050000 and Section 9.0 of
this SPPP for indicators of obvious stormwater pollutions such as color, odor, turbidity,
floating solids, settled solids, suspended solids, foam, oil sheen, and o t h e r obvious
indicators of stormwater pollution.
Results of the examination are documented using the NCDEQ's Stormwater Discharge
Outfall (SDO) Qualitative Monitoring Report in Appendix D.
8.3 Annual Update and Certification of Non-Stormwater Discharges

SECTION 9
MONITORING
9.1 Existing Data
The facility is not required to conduct analytical sampling/tests (General Permit No.
NCG050000 Part Il - Section B and C, as described below). The TruExterior facility assumed
ownership of the site on March 12,There are no historical stormwater analytical monitoring
data as the previous Facility was not required to conduct analytical monitoring.
9.2 Permit Requirements
9.2.1 Qualitative Monitoring
The Facility is required to sample stormwater discharges from industrial activity
areas on a semi-annual basis. After collecting the sample, the employee visually
inspects the sample observing color, odor, clarity, floating solids, suspended solids,
foam, oil sheen, erosion or deposition at the outfall, or other obvious indicators of
stormwater pollution. This sampling is to be performed in accordance with Part II -
Section C (Qualitative Monitoring Requirements) of the General Permit No.
NCG050000.
Qualitative Monitoring must be performed at each stormwater discharge outfall
(SDO) regardless of representative outfall status. The grab sample for visual
inspection must be taken within the first 30 minutes of discharge and conducted
during a representative storm event. 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 (3 days) 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. A minimum of 60 days must separate period 1 (January 1 to June 30 of
a given year) and period 2 (July 1 to December 31 of a given year). If a qualifying
storm cannot be sampled during a monitoring period, the reasons should be
documented. The next monitoring period's sampling should be conducted as soon as
possible. The requirements for this visual inspection, evaluation, and record
keeping/reporting are discussed in Part II -Section C and Part III -Section D of
General Permit No. NCG050000 and Sections 9 and 10 of this SPPP, respectively.
Results of the inspection are documented using the NCDEQ 's SDO Qualitative
Monitoring Report, which is attached in Appendix D.
9.2.2 Analytical Monitoring
As discussed in Section 8. 1, analytical testing is not required under General Permit
No. NCG050000. However, facilities covered under General Permit No.
NCG050000, that have any on -site vehicle maintenance activity using more
than 55 gallons of new motor oil per month are required to perform analytical

All permits require qualitative monitoring to be performed during a "measurable storm event."
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted siteoutfall. 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 DEMLRRegional Office.
By this signature, I certify that this report is accurate and complete to the best of my knowledge:

(See information below.)
1211Yes ❑ No
Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
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 (3 days) 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.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. 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 DWQ Regional Office.
