Section 1. Facility Activities and Process:
CertainTeed, LLC manufactures asphalt roofing. The site contains a finished product warehouse, factory
area, office, modified asphalt building, asphalt storage and processing areas, limestone crushing
operation, and dry storage building. These buildings contain asphalt shingle production lines, packaging
areas, quality assurance labs, material storage areas, and boiler and mechanical rooms. Five (5)
stormwater retention ponds are onsite and are where the outfalls originate from.
Per the 2015 permit renewal application, two (2) 1 million gallon tanks of asphalt storage with railroad
access was added, and two (2) acres of land was converted to finished product storage. Additionally, a
5th outfall was added and the facility is planning a large expansion on newly purchased property to the
south. Initial paperwork for erosion control is being reviewed and the permittee plans to get a separate
stormwater permit for this facility.
Outfall SW001:
Drainage area consist of truck and vehicle traffic and some raw material unloading.
Outfall SWO02:
Drainage area consist of truck and forklift traffic, shingle storage, and truck loading and unloading of
shingles.
Outfall SWO03:
Drainage area consist of truck and forklift traffic, shingle storage, and truck loading and unloading of
shingles.

Outfall SWO04:
Drainage area consist of truck and forklift traffic, shingle storage, asphalt processing, and raw material
unloading.
Outfall SWO06:
Added since last permit renewal. Drainage area consist of truck and forklift traffic, shingle storage, and
truck loading and unloading of shingles.
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR § 122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing, processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."

Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for January 2021 to March 2022. Quantitative sampling included pH, TSS, TN, TP, copper,
and VOCs/SVOCs.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the CertainTeed Corporation site.

Stormwater Benchmarks and Tiered Response: Rather than limits, North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan (SWPPP).
Page 5 of 8

Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:

Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology (BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site -specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) § 122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
Page 6 of 8

also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BAT/BCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• 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.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan (SWPPP) requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.
Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• eDMR requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
• Total hardness added to outfalls SW002, SW003, and SW004 as monitoring for hardness
dependent metal (copper) is required
• Outfall SW006 added per information provided during renewal

Section 5. Changes from draft to final:
• None
Section 6. Discussions with the Facility and Regional Office:
• Initial contact with facility: 7/22/2022
• Initial contact with Regional Office: 8/9/2022
• Draft sent to CO peer review: N/A (peer review skipped due to staff limitations)
• Draft sent to Regional Office: 10/12/2022
• Final permit sent for supervisor signature: 12/7/2022
Section 7. Comments received on draft permit:
Robert Yurek (CertainTeed; via email 10/19/2022): Why the change from semiannual sampling
to quarterly sampling?
o DEMLR response: The shift from semi-annual to quarterly monitoring is a
programmatic change. All individual industrial stormwater permits now require quarterly
monitoring for all pollutants of concern. More frequent monitoring allows for a more
accurate characterization of the effluent and protects water quality.

processes are all performed inside the facility.
At the front and rear of the facility there are several asphalt tanks. Heated asphalt is stored in the tanks. There are additional
tanks at the rear of the facility that contain oil. There is a railyard in this area as well. Certainteed has had to register as an
oil terminal because of the amount of oil stored/used onsite.
Packaged product is stored outsidearound the western side of the facility. Pallets, some scrap metal, and ground roofing
product. The ground roofing product was stockpiled away from drop inlets and with concrete containment walls around three
sides. This material is recyled and used onsite.
All ashpahlt and oil tanks have secondary containment.
The SWPPP was reviewed during the inspection. The responsible party should make sure the SWPPP is reviewed annually.
Even if there are no changes, the date can be updated on the cover.
There were no issues noted during the inspection. The facility appears to be well maintained, there were no spills or
evidence of residue in the areas observed outside.

Ms. Young.
Since your request I have pulled together all of your requested information mostly related to everything that has
happened related to stormwater since our 2015 renewal application.
The owner is correct as CertainTeed Corp.
Here are all of the changes to the facility and planned since our permit renewal. All changes prior and future have been
approved with the appropriate plans sent in.
Added more shingle storage and a 5t" outfall, numbered #6.
We are planning on a large expansion on the new property that we just purchased to the south. Initial
paperwork for erosion control is being reviewed as I write this. We hope to get this facility under a separate
stormwater permit.
Here are all the activities in the different drainage basins.
DB #1 Truck and vehicle traffic, some raw material unloading.
DB #2 Truck and forklift traffic, shingle storage, Truck loading and unloading of shingles.
DB #3 Truck and forklift traffic, shingle storage, Truck loading and unloading of shingles.
DB #4 Truck and forklift traffic, Shingle storage, Asphalt processing, Raw material unloading.
DB #6 Truck and forklift traffic, shingle storage, Truck loading and unloading of shingles.
All the GPS coordinates are on the spreadsheet of the monitoring data for the outfalls.
Enclosed are the monitoring data.
Please let me know if you need anything further?

Thank you for the update. Please note that although the outfalls may be marked on a site map, the exact coordinates for
all outfalls still need to be provided.

Thanks Ms. Young,
We will get you the information you requested. The only item that we don't have readily available is coordinates of the
outfall. The outfalls should be readily marked on the drawing and are in the corners of the plant. We do have a 5tn
outfall that has been added since the renewal in 2015.

Subject: Certainteed Corporation (NCS000140) stormwater permit application
Good afternoon,
I am working on renewing the individual stormwater permit for the Certainteed Corporation (NCS000140). I
need additional information in order to 1) confirm that the information I have is correct and 2) make sure the
permit adequately serves the needs of the facility. Please provide the following:
• Confirmation of the owner entity;
• Description of industrial activity in each drainage area;
• Confirmation on number of outfalls and coordinates of each outfall location;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s)
for the facility. Please review the facility information to make sure it is correct. Information can be updated
using the links provided below, where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact
Update Request Form
• Delegation of Signature Authority (DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form
• Facility contact: Permit Contact Update Request Form
• Facility address only: Email Bethany og ulias
• Stormwater outfall information: Email Bethany Geor og ulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePUment website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.

Please contact me if you have any questions.
Thank you,

Hello Robert,
Thank you for providing this information. I would like to confirm one more time who the owner entity is for the facility
and permit. According to the NC Secretary of State website, Certainteed Corporation is not a currently active
organization. Is the correct owner entity one of those listed on the attach document? If so, please let me know which
one as well as submitting the appropriate information related to name/ownership changes (more guidance can be found
on our website here under the "How to Update Permit Data" heading). Please let me know if you have any questions.

Ms. Young.
Since your request I have pulled together all of your requested information mostly related to everything that has
happened related to stormwater since our 2015 renewal application.
The owner is correct as CertainTeed Corp.
Here are all of the changes to the facility and planned since our permit renewal. All changes prior and future have been
approved with the appropriate plans sent in.
Added more shingle storage and a 5" outfall, numbered #6.

We are planning on a large expansion on the new property that we just purchased to the south. Initial
paperwork for erosion control is being reviewed as I write this. We hope to get this facility under a separate
stormwater permit.
Here are all the activities in the different drainage basins.
DB #1 Truck and vehicle traffic, some raw material unloading.
DB #2 Truck and forklift traffic, shingle storage, Truck loading and unloading of shingles.
DB #3 Truck and forklift traffic, shingle storage, Truck loading and unloading of shingles.
DB #4 Truck and forklift traffic, Shingle storage, Asphalt processing, Raw material unloading.
DB #6 Truck and forklift traffic, shingle storage, Truck loading and unloading of shingles.
All the GPS coordinates are on the spreadsheet of the monitoring data for the outfalls.
Enclosed are the monitoring data.
Please let me know if you need anything further?

Thanks Ms. Young,
We will get you the information you requested. The only item that we don't have readily available is coordinates of the
outfall. The outfalls should be readily marked on the drawing and are in the corners of the plant. We do have a 51n
outfall that has been added since the renewal in 2015.

Good afternoon,
I am working on renewing the individual stormwater permit for the Certainteed Corporation (NCS000140). 1

permit adequately serves the needs of the facility. Please provide the following:

• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit;
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.

Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility, contact information for the permit, and the regulated stormwater outfall(s) for the
facility. Please review the facility information to make sure it is correct. Information can be updated using the links
provided below, where applicable:

Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

BEST MANAGEMENT PRACTICES

BEST MANAGEMENT PRACTICES FROM THE STORMWATER POLLUTION PREVENTION PLAN
The following BMPs are in place at the CertainTeed facility:
• Secondary Containment — Secondary containment is provided for all storage tanks exposed to
storm water.
• Spill Kits — Spill kits are located near material storage areas including the still yard and the storage
buildings. The spill kits are inspected and material is replaced as needed.
• Inspections — An inspection program is in place for visually inspecting all BMPs. Inspections are
performed frequently on areas where materials are exposed to storm water and for all BMPs.
• Stormwater Retention Wetlands Maintenance Program — Details of the maintenance program for
the four stormwater retention wetlands are provided in the Draft September 2009 Stormwater
Best Management Practices Inspection and Maintenance Plan. The Plan includes specific
requirements for inspecting for clogs and excess debris, maintaining the vegetated areas,
inspecting the structural components, and evaluating the need for component replacement.
• Facility -wide Maintenance Program —The maintenance programs covers electrical equipment,
mechanical equipment, tanks, valves and pipes with potential to cause spills that could enter the
storm water system.
• Proper Storage of Finished Product — Finished product is properly stored with wraps and/or bags.
If wraps and/or bags are torn, finished product will be re -wrapped and/or re -bagged.
• Proper Labeling of Containers — All storage containers for chemicals, petroleum products, and
hazardous wastes are properly labeled for content and hazards.
• Proper disposal of waste materials — Waste disposal areas are identified throughout the site.
Wastes are segregated and disposed in appropriate containers.
• Good Housekeeping — Good housekeeping procedures are implemented to maintain a clean and
orderly work environment.
• Training — All facility personnel receive annual spill prevention briefings that include spill
prevention practices and response procedures.
