RE: PTI — Stormwater Management Plan Modification — Removal of Existing Stormwater Basin 134-A
and Replacement with Alternative Authorized Stormwater BMPs
Dear Ms. Higgins and Ms. Homewood:
I am writing in response to your January 11, 2019 letter request for additional information (RFAI)
regarding the plan of the Piedmont Triad Airport Authority (PTAA) to remove Basin 134-A (attached as
Exhibit 1) to construct our new Crossfield Taxiway.
Specific responses to the RFAI's six requests are set forth below and in the attached Jacobs/CH2M report
dated February 1, 2019, which is attached as Exhibit 2 (the "Jacobs Report"). This report was developed
in response to the RFAI and supplements Jacobs previous report dated December 6, 2018. However,
before addressing the specifics of the RFAI, I would like to convey PTAA's view of the regulatory and
permitting context to better explain PTAA's position and with the understanding that DEQ may disagree
with some of our views.
Regulatory and Permitting Context
As an initial matter, it appears to PTAA that the removal of Basin 134-A has already been approved by
DEQ per the issuance of WQC004053 dated March 11, 2016 for PTAA's taxiway construction project
(Exhibit 3), which expressly incorporated the taxiway construction plans and made the plans an
enforceable part of the certification, and the Corps of Engineer's issuance of 404 Permit SAW -2012-
01547 dated March 15, 2016 (Exhibit 4). 1 understand that DEQ disagrees with this view and maintains
that additional written authorization is needed for the removal of Basin 134-A because the Basin is part
of the Stormwater Management Plan required in Condition 8 of WQC 3428 dated November 10, 2003
(Exhibit 5). PTAA respects DEQ's view on this issue and is certainly willing, without waiving its own
position, to provide information necessary to satisfy DEQ that removal of the Basin complies with all
stormwater and water quality regulations.

SPT/
PIEDMONT TRIAD AIRPORT AUTHORITY
Second, PTAA respectfully submits that no formal modification of WQC 3428 is necessary since
Condition 8 of WQC 3428 allows changes to be made in the required stormwater management plans
with the "written authorization of the Division." Since provision is made in WQC 3428 to make changes
in the stormwater plan, there should be no need to modify the certificate to make the changes but only
the "written authorization" that is contemplated by the certificate.
Finally, in PTAA's view, the applicable stormwater control requirements for runways and taxiways are
controlled by N.C. Gen. Stat. §§ 143-214.7(c3) and (c4), under which alternatives to Basin 134-A should
be "deemed permitted" and approved by DEQ if the alternative measures comply with DEQ's
Stormwater Design Manual Parts E-4 and C-10. Nevertheless, in addition to the design measures, the
information provided by PTAA's consultants, including in the Jacobs Report and the additional
information provided below, demonstrates that the planned removal of Basin B4 -A and replacement
with alternative stormwater control measures will not result in any violation of water quality standards.
Response to RFAI Requests
Below (in bold text) are the information requests in the RFAI, along with corresponding responses (in
normal text), which largely rely on and refer to the Jacobs Report for a more detailed analysis.
1. Please provide a detailed overall drawing that clearly shows the location of Basin 1134-A within the
airport facility.
See Appendix A "Basin 64-A Location Map" in the Jacobs Report.
2. Provide a detailed analysis of all existing stormwater currently directed to Basin B4 -A and include
clear description of stormwater sources and how they are conveyed to the basin. This should
include a description/discussion of all potential pollutants to be present within the existing
stormwater.
Please see Appendix A and Appendix B of the Jacobs Report. Appendix B graphically depicts the
watershed from which stormwater is currently conveyed into Basin 134-A. Also see Section 2 of the
Jacobs Report, which provides a detailed written description of the stormwater sources and
conveyance to Basin 134-A.
As to a description of all potential pollutants, please note that Chapter E-4 of the NCDEQ
Stormwater Design Manual, which is also summarized in Section 3.1 of the Jacobs Report, identifies
the following typical pollutants of concern at airports:
Pollutants of concern at airports include typical urban pollutants (nitrogen, phosphorus, sediment,
hydrocarbons, and heavy metals) and airport -specific pollutants (de-icing fluid, urea, and aviation
fuels such as avgas and jet fuel).
It is not expected that there will be any potential pollutants in stormwater in the Basin 64-A
drainage area other than those identified above. Please also note that no aircraft de-icing activities
occur within the drainage area of Basin 134-A as shown in Figure 3-1 in the Jacobs Report, and so no
4836-4878-8102.v1

irrPT/
PIEDMONT TRIAD AIRPORT AUTHORITY
glycol or other pollutants related to aircraft de-icing are expected to be present in the stormwater
within the drainage area.
3. Please provide a drawing that shows any NPDES outfall sampling points that are currently
tributary to this basin or below the outfall of this basin. For any such locations please provide all
sampling results for each location for the last year.
No NPDES stormwater discharge outfall (SDO) sampling points are currently tributary to Basin 134-A
or below the outfall of this basin. In -Stream (IS, not outfall) sampling locations (#05 and #06) are set
in Brush Creek, downstream of Basin 134-A. Attached as Exhibit 6 are the monitoring results at these
In -Stream locations in the past year. These results do not indicate any exceedance of the water
quality standards (DO, turbidity, PH and acute toxicity) that are monitored at those locations. All of
the results are from winter months since NPDES permit only calls for in -stream monitoring following
de-icing events.
4. Please clarify if this basin is addressed within your Individual NPDES stormwater permit. If so,
please provide documentation from the Division of Energy, Mineral and Land Resources (DEMLR)
that removal of this basin would be allowed under the NPDES program.
Basin 134-A is not currently sampled, or otherwise addressed, in the Airport's Individual NPDES
Stormwater Permit (NCS000508) (Exhibit 7) or in the Stormwater Pollution Prevention Plan that was
adopted by PTAA as required by the NPDES permit.
Part I, Section A of the NPDES permit states that "Discharges covered in this permit are the
stormwater discharges from the current airport operations (001 through 066) as well as additional
stormwater discharge points that may be created by further modification or expansion of airport
operations." It is PTAA's understanding that modification of the NPDES Discharge Monitoring
program to add potential sampling locations at the basins adjacent to Runway 5L/23R will not be
required until there is additional industrial development in that area.
S. Please provide a detailed analysis of all proposed stormwater drainage areas and conveyance
methods for the proposed grading once Basin 134-A is removed, including delineation of the
receiving vegetated areas, storm water discharge volume and velocity. For any new impervious
surfaces please provide an analysis of the potential for pollutants to be present within the
stormwater (de-icing activities is of particular concern).
Please refer to Section 4 of the Jacobs Report for a detailed analysis of the proposed grading and
stormwater conveyance after the removal of Basin B4 -A, including conveyance through the
vegetated area bordering Runway 5L/23R, the new vegetated area that will border the new taxiway,
and a new grass swale that will be created within the former Basin 134-A site. Graphic
representations are shown Appendices C, D, and E of the report. The same typical airport pollutants
would be expected as detailed in Section 3.1 of the Report. As pointed out above, aircraft de-icing
activities will not occur in this vicinity, so there should be no glycol or other aircraft de-icing agents
in the stormwater runoff within the Basin 64-A watershed.
4836-4878-8102.v1

6. Provide a detailed analysis to show that after removal of Basin 134-A all stormwater will meet the
criteria outlined Part E-4 (Airports) and Part C-10 (Disconnected Impervious Surface) of the
Stormwater Design Manual.
Please refer to Jacobs Report, Sections 4.4 "Additional BMP's," demonstrating compliance with the
applicable provisions of the Stormwater Design Manual.
Thank you both and DEQ for your attention and consideration. We would like to schedule a meeting
and site visit with you at your earliest convenience so that we may cooperatively and efficiently
discuss any issues, questions, or concerns that you may have, and provide any further information
necessary for DEQ to concur that PTAA may proceed with its planned removal of Basin B4 -A.

Basin B4 -A Water Quality Report JACOBS Ch2 U-
1. Introduction
This report was created to serve as an addendum to the original report "Basin B4 -A Report" dated
December 6, 2018 and is intended to focus on the water quality aspect associated with Basin B4 -A and
its existing watershed. This report was drafted in response to questions received in a letter dated January
11, 2019 from the North Carolina Department of Environmental Quality (DEQ) and subsequent discussion
with DEQ staff on January 15, 2019.
2. Existing Stormwater Management Basin 134-A
Basin B4 -A is one (1) of thirteen (13) basins that were installed to satisfy the then existing stormwater
quality requirements as part of the project to construct Runway 5L/23R in the early 2000's. Basing B4 -A is
shown in Appendix A "Basin B4 -A Location Map" of this report.
2.1 Existing Stormwater Runoff to Basin B4 -A
Appendix B "Existing Basin B4 -A Drainage Area" graphically shows the drainage area and existing
infrastructure associated with Basin B4 -A. Currently stormwater runoff runs from the crown of Runway 5L -
23R across 75' of runway pavement and an additional 35' of shoulder pavement before reaching a
vegetated receiving area for disconnected pavement known as the Runway Safety Area (RSA). The RSA
is turfed, 140' wide, and runs the entire length of the runway. Based on FAA specifications the safety area
cannot exceed 3% in grade. Once the water exits the safety area it is collected into a series of drop inlets
and pipes, before being directed to Basin B4 -A. Additionally, there is a portion of the airport service road
runoff that is controlled by Basin B4 -A. As a private airport road, the traffic and resulting pollutants
created by use of this road are extremely minor. The service road is only used sparingly for airport
personnel. (Section 3.1 of this report lists the typical pollutants from airport operations)
This report also analyzes the peak runoff to the basin. The 10 -year peak discharge rate for the existing
Basin B4 -A drainage area was calculated to be 78 cfs. This calculation used the Rational Method as
shown below:
Q = CiA
where:
Q = peak runoff (cfs)
C = weighted runoff coefficient
i = rainfall intensity (in/hr)
A = drainage area (acres)
The weighted runoff coefficient (C) was found to be 0.49. This was based on 83% of the drainage area
being grassed (0.4) and 17% being impervious (0.95). C values were based on City of Greensboro, Storm
Drainage Design Manual, February 2008.
The rainfall intensity (i) was found to be 2.76 in/hr, by using a time of concentration calculated at 45
minutes and the rainfall intensity (IDF) tables for the City of Greensboro shown in Appendix F of this
report.
The total drainage area (A) being served by Basin B4 -A is 57 acres.
The above provided parameters are illustrated on Appendix B "Existing Basin B4 -A Drainage Area".

JACOBS ChZM• Basin B4 -A Water Quality Report
3. Justification to Remove Stormwater Management
Basin B4 -A
Crossfield Taxiway Phase — 1 will impact the existing stormwater management Basin 134-A that was
constructed at the time Runway 5L/23R was built. Preliminary grading and impacts associated with the
Crossfield Taxiway site were previously shown on the approved 401 certification for the taxiway.
There is a safety concern with this basin in place. Even extended dry detention basins attract wildlife
which can present a serious threat to the safety of aircraft operations at airports. Basin B4 -A has been
witnessed by airport staff to routinely attract Canada Geese, among other wildlife. It is PTAA's desire to
remove all of Basin 134-A as part of the taxiway project. Section E-4 of the North Carolina Stormwater
Design Manual prescribes specialized water quality controls for airports to reduce the wildlife hazard,
recognizing that runways and taxiways are surrounded by a large amount of open space and that airfield
runoff typically has very low concentrations of pollutants. This report will identify the Best Management
Practices (BMP's) currently in place and the new BMP's for the taxiway that will continue to protect water
quality after the removal of Basin 134-A.
3.1 Potential Airfield Pollutants
Currently Basin 134-A controls runoff from a portion of Runway 5L -23R, on its northwest side, as shown in
Appendix B "Existing Basin 134-A Drainage Area". Section E-4 of the NC Stormwater Design Manual
states the following in respect to typical pollutants at airports, "the pollutants of concern include typical
urban pollutants like nitrogen, phosphorus, sediment, hydrocarbons, and heavy metals as well as airport -
specific pollutants such as de-icing fluid, urea, and aviation fuels. Based on samples collected at the
Wilmington Airport, runoff from runways and taxiways can be significantly cleaner than runoff from typical
urban areas, indicating that airports may not have quite as many urban pollutants as roads and
highways".
No pollutants other than the typical airport pollutants identified above are expected to be present in the
existing Basin B4 -A drainage area or in any runoff that reaches Basin 134-A. Additionally, although aircraft
are de-iced at PTI, no aircraft de-icing agents are present in the existing Basin B4 -A drainage area or in
any runoff that reaches Basin 134-A because these activities are handled on the other side of the airport
as indicated below in Figure 3-1.

4. Proposed Crossfield Taxiway Project
4.1 Phase 1
Phase 1 of the Proposed Crossfield Taxiway Project will provide grading for most of the taxiway corridor,
including the portion within the Basin B4 -A drainage area, as shown in Appendix C "Proposed Basin B4 -A
Drainage Area (Phase 1)". Considering there will be no taxiway paving in phase 1, there will be virtually
no increase in peak stormwater discharge or pollutants. When Basin B4 -A is removed, stormwater that
previously entered the basin from the two existing culverts will be redirected to a vegetated swale
(Swale 1) via a proposed culvert shown in Appendix E "Basin B4 -A Removed (Enlarged)".
Swale 1, will be installed in phase 1, however it is sized to carry a peak stormwater runoff of 79 cfs,
which is based on the 10 -year storm event after Phase 2 is completed. See section 4.3 below for more
detailed information concerning Swale 1.
The only changes in the peak runoff between the existing conditions and after Phase 1 are with respect to
the runoff coefficient and drainage area. These parameters are illustrated in Table 4-1 below:

4.2 Phase 2
Phase 2 will consist of completing the grading and paving of Crossfield Taxiway as shown in Appendix D
"Proposed Basin 134-A Drainage Area (Phase 2)". Stormwater conveyance for phase 2 will stay the same
as it was for phase 1, however stormwater will run from the crown of the newly paved taxiway across 37.5
feet of taxiway pavement and an additional 30 feet of shoulder pavement. Once stormwater runs off the
paved surfaces it will reach a vegetated receiving area for disconnected pavement known as the Taxiway
Safety Area (TSA). The TSA in this case will be 39.5 feet wide, turfed and per FAA standards the slope
will not exceed 3%. This TSA will run the entire length of the Taxiway, including the portion of the taxiway
that is within the Basin 134-A drainage area.
There will be a de minimis increase in peak runoff in the 10 -year storm event due to the additional airfield
pavements. The new 10 -year peak runoff will be 79 cfs. The drainage area (A) and rainfall intensity (i) will
be unchanged. All the peak discharge values can be seen below in Table 4-2.

Rainfall Intensity (i) 2.76 2.76 2.76
Drainage Area (A) 57 55.3 55.3
Peak Runoff (0) 78 76 79
4.3 Swale 1
As stated in section 4.1, Swale 1 was designed to accommodate the increased runoff from the Crossfield
Taxiway project. The normal depth of water within the swale during the 10 -year storm will be 18 inches.
The swale will be constructed with a minimum depth of 36 inches, providing for 18 inches of freeboard.
The longitudinal slope of the swale will be 0.78% and the sides will be constructed at a 6:1 slope. The
10 -year velocity will be 5.86 feet per second. The swale will be planted with a Bermuda grass mix so that
the velocity will fall below the allowable velocities for soils made up of clay mixes which is typical for this
location. Appendix H includes the complete table for allowable velocities in grassed lined channels.
During construction, erosion will be controlled through the use of erosion control matting and check
dams. Erosion control matting will help stabilize and hold seed in place until grass can be grown. Using
check dams will "reduce erosion in the drainage channel by reducing the velocity of flow" according to
Chapter 6.83 of the North Carolina Erosion and Sediment Control Planning and Design Manual.
Swale calculations are found in Appendix G of this report.
After stormwater exits Swale 1, it is directed into a 40' x 40' rip rap bed to further dissipate the velocity.
Stormwater then will follow the same overland path as it does now before entering the 10' x 12' box
culvert shown in Appendix E "Basin 64-A Removed (Enlarged)". Currently the velocity is controlled in this
box culvert by a low flow channel with equally spaced weirs and a series of dissipater curbs prior to the
outfall of the box culvert. There have been no noted erosion issues at the outfall of the box culvert since

Basin B4 -A Water Quality Report
JACOBS Ch2M-
its installation in the early 2000's. As shown in the Basin 64-A Report, dated December 6, 2018, the box
culvert could easily handle the increased peak runoff from the construction of the Crossfield Taxiway and
removal of Basin 134-A. The 10 -year peak runoff after removing Basin 134-A will only utilize 7.8% of the
capacity of the box culvert. We expect the box culvert to provide the same level of control with respect to
velocity after the removal of Basin B4 -A, therefore no additional downstream erosion is expected.
4.4 Additional BMP's
At airports, runways, taxiways, and other areas that provide for overland stormwater flow that promote
infiltration and treatment of stormwater into grassed buffers, shoulders, and grass swales shall be
deemed permitted pursuant to the State post -construction stormwater requirements. It is our
understanding that based on studies referenced in the Division of Water Quality's BMP manual runways
and taxiways create very little TSS, nutrients or pollutants. The manual also recognizes that runways and
taxiways are surrounded by large disconnected spaces and vegetated areas. For these reasons, the
manual concludes that water quality will be adequately protected as long as airfield areas comply with the
regulatory requirements for Disconnected Impervious Surfaces as outlined in Part E-4 and Part C-10 of
the manual. Table 4-4.1 below compares the required parameters for disconnected pavement and the
"safety" areas we are providing that will also perform as vegetated receiving areas.

`While the paved area for the runway slightly exceeds the 100' parameter, it is important to note that the
adjacent vegetated receiving area is 14 times larger than the minimum requirement and the slope of the
vegetated area (3%) is less than half of the 8% maximum.
It is our belief that, by providing much larger and flatter vegetated receiving areas than required by the applicable
design criteria, the vegetated receiving areas for the runway and taxiway will allow for longer contact time with
stormwater runoff and will provide adequate water quality measures, in accordance with Chapter E-4 of the North
Carolina Stormwater Design Manual, after the removal of Basin B4 -A. .

JACOBS Ch2AI ,. Basin B4 -A Water Quality Report
5. Conclusion
The stormwater management Basin B4 -A can be safely removed and sufficient stormwater control and
water quality protection will still be achieved through the methods discussed in section 4.3 of this report.
In addition, the report "Basin 134-A Report" dated December 06, 2018 and submitted previously shows
that the existing drainage system will safely convey storm events up to the 100 -year storm even if Basin
134-A is removed.

3) Drainage Area = A
The acreage of the watershed in question can be computed from topographic
maps by marking the ridgelines and planimetering the designated areas. The City
of Greensboro uses a 1" = 200' scale map with a 2 -foot interval contour for
designing and checking storm sewer. Copies of these maps are available both
digitally and in hard copy and may be purchased from the Engineering Records
Section of the City of Greensboro Engineering & Inspections Department or the
GIS Division of the MIS Department.
Once the values for C, I, and A are determined it is a simple procedure to
calculate the peak discharge rate for the site using the equation, Q = CIA

S. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas
beyond the footprint of the impacts depicted in the Pre -Construction Notification for this
project. All construction activities, including the design, installation, operation, and
maintenance of sediment and erosion control Best Management Practices shall be
performed so that no violations of state water quality standards, statutes, or rules occur.
Approved plans and specifications for this project are incorporated by reference and are
enforceable parts of this permit. [15A NCAC 02H .0501 and .05021
6. Erosion and sediment control practices must be in full compliance with all specifications
governing the proper design, installation and operation and maintenance of such Best
Management Practices. If applicable, the project must comply with the specific conditions
and requirements of the NPDES Construction Stormwater Permit issued to the site and the
following requirements [15A NCAC 02H .0506(b)(3) and (c)(3)]:
a. Design, installation, operation, and maintenance of the sediment and erosion
control measures must be such that they equal or exceed the requirements specified
in the most recent version of the North Carolina Sediment and Erosion Control
Manual. The devices shall be maintained on all construction sites, borrow sites, and
waste pile (spoil) projects, including contractor -owned or leased borrow pits
associated with the project.
b. For borrow pit sites, the erosion and sediment control measures must be designed,
Installed, operated, and maintained in accordance with the most recent version of
the North Carolina Surface Mining Manual.
c. Reclamation measures and implementation must comply with the reclamation in
accordance with the requirements of the Sedimentation Pollution Control Act and
the Mining Act of 1971.
d. Sufficient materials required for stabilization and/or repair of erosion control
measures and stormwater routing and treatment shall be on site at all times.
6. Sediment and erosion control measures shall not be placed in wetlands or waters.
Exceptions to this condition require application submittal to and written approval by the
Division. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, then design and placement of temporary erosion control measures shall not
be conducted in a manner that may result in dis-equilibrium of wetlands, stream beds, or
banks, adjacent to or upstream and downstream of the above structures. All sediment and
erosion control devices shall be removed and the natural grade restored within two (2)
months of the date that the Division of Energy, Mineral and Land Resources (DEMLR) or
locally delegated program has released the specific area within the project. [15A NCAC 02H
.0501 and .05021

7. An NPDES Construction Stormwater Permit is required for construction projects that disturb
one (1) or more acres of land. This Permit allows stormwater to be discharged during land
disturbing construction activities as stipulated in the conditions of the permit. if your
project is covered by this permit, full compliance with permit conditions including the
erosion & sedimentation control plan, inspections and maintenance, self-monitoring, record
keeping and reporting requirements is required. A copy of the general permit
(NCG010000), inspection log sheets, and other information may be found at:
http:/Iportal.ncdenr.orit/web/wg/ws/su/npdessw#tab-w. 15A NCAC Q2H .0506(b)(5) and
(c)(5)]
8. All work in or adjacent to stream waters shall be conducted so that the flowing stream does
not come in contact with the disturbed area. Approved best management practices from the
most current version of the NC Sediment and Erosion Control Manual, or the NC DOT
Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams,
and other diversion structures shall be used to minimize excavation in flowing water. [15A
NCAC 02H .0506(b)(3) and (c)(3)]
9. If concrete is used during the construction, then all necessary measures shall betaken to
prevent direct contact between uncured or curing concrete and waters of the state. Water
that inadvertently contacts uncured concrete shall not be discharged to waters of the state
due to the potential for elevated pH and possible aquatic life/fish kills. 115A NCAC 02B.0200]
10. Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered and to allow for aquatic life movement during low flows. Existing
stream dimensions (including the cross section dimensions, pattern and longitudinal profile)
must be maintained above and below locations of each culvert. [15A NCAC 02H .0506(b)(2)
and (c)(2)]
Placement of culverts and other structures in waters, streams must be below the elevation
of the streambed by one (1) foot for all culverts with a diameter greater than 48 inches, and
20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to
allow low flow passage of water and aquatic life.
installation of culverts in wetlands must ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions. Additionally, when
roadways, causeways, or other fill projects are constructed across FEMA -designated
floodways or wetlands, openings such as culverts or bridges must be provided to maintain
the natural hydrology of the system as well as prevent constriction of the floodway that
may result in destabilization of streams or wetlands.
The establishment of native, woody vegetation and other soft stream bank stabilization
techniques must be used where practicable instead of rip rap or other bank hardening
methods.

11. All temporary fill and culverts shall be removed and the impacted area returned to natural

a. Design, installation, operation, and maintenance of the sediment and erosion
control measures must be such that they equal or exceed the requirements specified
In the most recent version of the North Carolina Sediment and Erosion Control
Manual. The devices shall be maintained on all construction sites, borrow sites, and
waste pile (spoil) projects, Including contractor -owned or leased borrow pits
associated with the project.
b. For borrow pit sites, the erosion and sediment control measures must be designed,
Installed, operated, and maintained in accordance with the most recent version of
the North Carolina Surface Mining Manual.
c. Reclamation measures and implementation must comply with the reclamation In
accordance with the requirements of the Sedimentation Pollution Control Act and
the Mining Act of 1971.

Exceptions to this condition require application submittal to and written approval by the
Division. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, then design and placement of temporary erosion control measures shall not
be conducted In a manner that may result In dis-equilibrium of wetlands, stream beds, or
banks, adjacent to or upstream and downstream of the above structures. All sediment and
erosion control devices shall be removed and the natural grade restored within two (2)
months of the date that the Division of Energy, Mineral and land Resources (DEMUR) or
locally delegated program has released the specific area within the project 115A NCAC 02H
.0501 and .05021

7. An NPDES Construction Stormwater Permit is required for construction projects that disturb
one (1) or more acres of land. This Permit allows stormwater to be discharged during land
disturbing construction activities as stipulated in the conditions of the permit. If your
project is covered by this permit, full compliance with permit conditions including the
erosion & sedimentation control plan, inspections and maintenance, self-monitoring, record
keeping and reporting requirements is required. A copy of the general permit
(NCG010000), inspection log sheets, and other information may be found at:
htto://Portal.ncdenr.or#Jweb/wo/ws/sulnodessw#tab-w. 15A NCAC 02H .0506(b)(5) and
(c)(5))
S. All work in or adjacent to stream waters shall be conducted so that the flowing stream does
not come in contact with the disturbed area. Approved best management practices from the
most current version of the NC Sediment and Erosion Control Manual, or the NC DOT
Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams,
and other diversion structures shall be used to minimize excavation in flowing water. [15A
NCAC 02H .0506(b)(3) and (c)(3))
9. if concrete Is used during the construction, then all necessary measures shall betaken to
prevent direct contact between uncured or curing concrete and waters of the state. Water
that inadvertently contacts uncured concrete shall not be discharged to waters of the state
due to the potential for elevated pH and possible aquatic life/fish kills. [15A NCAC 028.0200]
10. Culverts required for this project shall be Installed in such a manner that the original dream
profiles are not altered and to allow for aquatic life movement during low flows. Existing
stream dimensions (including the cross section dimensions, pattern and longitudinal profile)
must be maintained above and below locations of each culvert. (15A NCAC 02H .0506(b)(2)
and (c)(2))
Placement of culverts and other structures in waters, streams must be below the elevation
of the streambed by one (1) foot for all culverts with a diameter greater than 48 Inches, and
20 percent of the culvert diameter for culverts having a diameter less than 48 Inches, to
allow low flow passage of water and aquatic life.
Installation of culverts In wetlands must ensure continuity of water movement and be
designed to adequately accommodate high water or flood conditions. Additionally, when
roadways, causeways, or other fill projects are constructed across FEMA -designated
floodways or wetlands, openings such as culverts or bridges must be provided to maintain
the natural hydrology of the system as well as prevent constriction of the fioodway that
may result in destabilization of streams or wetlands.
The establishment of native, woody vegetation and other soft stream bank stabilization
techniques must be used where practicable Instead of rip rap or other bank hardening
methods.

11. All temporary fill and culverts shall be removed and the impacted area returned to natural
conditions, within 60 days of the determination that the temporary Impact is no longer
necessary. The impacted areas shall be restored to original grade, including each stream's
original cross sectional dimensions, plan form pattern, and longitudinal bed and bed profile,
and the various sites shall be stabilized with natural woody vegetation (except approved
maintenance areas) and restored to prevent erosion. 115A NCAC 02H .0506(b)(2) and (c)(2))
12. All temporary pipes/culverts/riprap pads etc, shall be installed in all streams as outlined in the
most recent edition of the North Carolina Sediment and Erosion Control Planning and Design
Manual so as not to restrict stream flow or cause dis-equilibrium. [15A NCAC 02H .0506(b)(2)
and (c)(2))
13. Any riprap required for proper culvert placement, stream stabilization, or restoration of
temporarily disturbed areas shall be restricted to the area directly impacted by the approved
construction activity. All riprap shall be buried and/or "keyed In" such that the original
stream elevation and streambank contours are restored and maintained. Placement of riprap
or other approved materials shall not result in de -stabilization of the stream bed or banks
upstream or downstream of the area. [15A NCAC 02H .0506(b)(2))
14. Any riprap used for stream stabilization shall be of a size and density to prevent movement by
wave action, current action, or stream flows and consist of clean rock or masonry material
free of debris or toxic pollutants. Riprap shall not be installed In the streambed except In
specific areas required for velocity control and to ensure integrity of bank stabilization
measures. (15A NCAC 02H .0506(b)(2))
15. A one-time application of fertilizer to re-establish vegetation Is allowed in disturbed areas
including riparian buffers, but is restricted to no closer than 10 feet from top of bank of
streams. Any fertilizer application must comply with all other Federal, State and local
regulations. [15A NCAC 02B.0267(6) and 15A NCAC 028.0231)
16. This Certification does not relieve the applicant of the responsibility to obtain all other
required Federal, State, or Local approvals.
17. Mr. Alex Rosser and Piedmont Triad Airport Authority shall conduct construction activities in a
manner consistent with State water quality standards (including any requirements resulting
from compliance with section 303(d) of the Clean Water Act) and any other appropriate
requirements of State and Federal law. 115A NCAC 026.02001 if the Division determines that

NORTH CAROLINA 401 WATER QUALITY CERTIFICATION
THIS CERTIFICATION is issued in conformity with the requirements of Section 401 Public Laws 92-500 and
95-217 of the United States and subject to the North Carolina Division of Water Quality (DWI) Regulations in 15
NCAC 2H, Section .0500 to. the Piedmont Triad Airport Authority (PTAA) for the discharge of fill into the
jurisdictional waters of Brush Creek and its unnamed tributaries, including approximately 23.44 acres of wetlands
and 12,846 linear feet of streams associated with the Proposed Runway 51MR, Proposed New Overnight Express
Air Cargo Sorting and Distribution Facility, and Associated Developments at Piednwnt.Triad International Airport,
Guilford County, North Carolina, pursuant to an application filed on 5th day of February of 2002.
The application and supporting documentation provides adequate assurance that the proposed work will not result
in a violation of applicable Water Quality Standards and discharge guidelines. Therefore, the State of North
Carolina certifies that this activity will not violate the applicable portions of Sections 301, 302, 303, 306, 307 of
PL 92-500 and PL 95-217 if conducted in accordance with the application, the supporting documentation, and
conditions hereinafter set forth.
This approval is only valid for the purpose and design submitted in the application materials and as described in
the Public Notice. If the project is changed, prior to notification a new application for a new Certification is
required. If the property is sold, the new owner must be given a copy of the Certification and approval letter and is
thereby responsible for complying with all conditions of this Certification. Any new owner must notify the
Division and request the Certification be issued in their name. Should wetland or stream fill be requested in the
future, additional compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h) (6) and (7).
For this approval to be valid, compliance with the conditions listed below is required.
Conditions of Certification:
1. Sediment and erosion control measures shall adhere to the design standards for sensitive
watersheds [15A NCAC 4B .00241; see NCDOT publication, Best Management Practices for the
Protection of Surface Waters (March 1997);
2. The, turbidity standard shall not be exceeded as described in 15 A NCAC' 2B .0200. Appropriate
sediment and erosion control practices must be used to meet this standard;
3. All sediment and erosion control measures placed in wetlands and waters shall be removed and the
original grade restored within two months after the Division of Land Resources has released the
Project:
4. Appropriate sediment and erosion control practices which equal or exceed those outlined in the
most recent version of the "North Carolina Sediment and Erosion Control Planning and Design
Manual" or the "North Carolina Surface Mining Manual" whichever is more appropriate (available
from the Division of Land Resources (DLR) in the DENR Regional or Central Offices) shall be in
full compliance with all specifications governing the proper design, installation and operation and
maintenance of such Best Management Practices in order to assure compliance with the
appropriate turbidity water quality standard;
Culverts:
5. Culverts required for this project shall be installed in such a manner that original stream profiles
are not altered. Existing stream dimensions (including the cross section dimension, pattern, and
longitudinal profile) are to be maintained above and below the locations of each culvert. Culverts
shall be designed and installed to allow for aquatic life movement as well as to prevent head
cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream
2

Mr. Mickie Bkoo e
November 10, 20M
grade shall be ie -established. If the pipes are installed in a perched manner, .the pipes shall be
removed and re -installed correctly.
The culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the
stream up -or down -stream of the culvert(s). Existing stream dimensions (including the cross
section dimension, pattern and longitudinal profile) are to be maintained above and below
locations of each culvert.
Native, woody vegetation and other soft stream bank stabilization techniques must be used where
practicable instead of rip -rap or other bank hardening methods. If rip -rap is necessary, it shall not
be placed in the stream bed, unless specifically approved by the Division of Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions;
6. Mitigation must be provided for the proposed impacts as specified in the tables below and as
described in the Wetland and Stream Mitigation Plan prepared by LawOibb (iroup?MACTEC
(December 28, 2001) and the Conceptual Mitigation Report prepared by EcoScience (February
2002). The Conceptual Mitigation Report notes that up to 6,840 linear feet of stream restoration
wr'fl be achieved onsite.' For the purposes of this CertWrAdon, 6,539 linear feet of restoration at
Causey Farms will be required to satisfy the requirements of 15A NCAC .0506(hx6). The
remaining 301 linear feet of restoration credits will be available. for use by the PTAA for stream
mitigation should design constraints necessitate minor increases in stream fill. A final stream and
wetland mitigation plan must be approved in writing by the Division of Water Quality before any
permanent facilities associated with this project are occupied. Additionally, the compensatory
mitigation plan must be completely constructed and implemented according to the plans approved
by the Division before any permanent facilities associated with the project are occupied. The
mitigation sites must be maintained according to the approved plan and permanently protected by
the use of conservation easements or similar protections. If the Division determines that any of the
mitigation projects are not constructed or performing according to the approved plans, the Division
shall notify you in writing and corrective action shall be completed within 6 months according to
the approved plans. Any repairs or adjustments to the mitigation sites must be made according to
the approved plan or must receive prior written approval from the Division. Two copies of an as -
built report as well as annual reports shall be sent to the Division by April 1" of each year for the
entire length of the five year monitoring period;

3

Mr. MkWe Elmore
November 10. 2003
8. The final, written stormwater management plan for each of the four phases of this project
(including a signed and notarized Operation and Maintenance Agreement) shall be approved in
writing by the Division of Water Quality before the impacts associated with the corresponding
phase of the project occur. The stormwater management plan must include plans and
specifications for stormwater management facilities that are appropriate for surface waters
classified as WS -III, appropriate for use in proximity to runways and designed to remove 85%
Total Suspended Solids on an annual average basis according to the NC Department of
Environment and Natural Resources Stormwater Best Management Practices Manual (April,
1999). These facilities must be designed to treat the runoff from the entire project, unless
otherwise explicitly approved by the Division of Water Quality. Also, before any of the new
facilities are used at the Piedmont Triad International Airport, the facilities (as approved by the
Division) shall be constructed and operational, and the stormwater management plan (as approved
by the Division) shall be implemented. The structural stormwater practices as approved by the
Division as well as drainage patterns must be maintained in perpetuity. No changes to the
structural stormwater practices shall be made without written authorization from the Division. The
four phases include:
8a. Fedex Site,
8b. Bryan Boulevard Relocation,
8c. Runway 5LMR, and
8d. Crossfield taxiway.
8e. Within ane year of your receipt of this Certification, the retro -fit stormwater control plan as
necessary to meet Water Quality Standards for the entire Piedmont Triad International
Airport and areas associated with the Horsepen Creek mitigation area shall be submitted to
the Division for written approval. Before any facilities associated with any of the four
phases of this project are occupied, written approval for the retro -fit stormwater plan must
be obtained from the Division;
9. The combined performance of the stormwater control measures must be modeled for lr 2, 5, and 10
year pre -and post -construction discharge events to ensure that downstream peak flows and the
resultant streambank stability (downstream to Lake Ifiggins for Brush Creek and downstream to Latae
Brandt for Horsepen Creek) are not amplified by the simultaneous, combined releases from the
stormwater control measures from the entire PTAA property. The release rates for stormwater
management facilities must be designed based on the modeling to prevent amplification of peak
flows. The above designs must be approved in writing by this The Division before any of the facilities
which are tributary to each of the stormwater control devices is occupied or opened for use. In
addition, the stormwater management facilities, as approved by the Division, must be constructed and
operational, prior to the occupation or use of the facilities authorized herein;
10. An additional stormwater management plan (including a spill containment and treatment failure plan)
must be provided to ensure that Surface Water Quality Standards are not violated as the result of
runoff contammatim by deicing and/or similar agents that are applied to aircraft or paved surfaces.
The plan must include means to collect the runoff that occurs during or following the application of
the above agents and must include a means to treat the pollutants in runoff to levels that comply with
Surface Water Quality Standards. The plan must include the procedures, design plans and
specifications necessary to achieve compliance with Water Quality Standards. The plan must be
approved by the Division of Water Quality within one year of the date of issuance of the 404 Permit.
Additionally, before the impacts associated with the first phase of the project to be constructed will
occur, procedures and infrastructure must be in place and operational. The plan must be implemented
as approved by the Division of Water Quality;
4

Mr. Midde Elm=
November 10, 2003
11. Additionally, any increase in duration of discharges in excess of the pre -construction channel
forming discharge must be evaluated to determine the effects on downstream stream bed and bank
stability (downstream to Lake Higgins for Brush Creek and downstream to Labe Brandt for
Horsepen Creek) from the entire PTAA property. In order to make this determination, the duration
of the 1, 2, 5 and 10 year pre -construction discharges that are in excess of the peak pre-
construction 1 year discharge must be compared to the duration of the 1, 2, 5 and 10 year post -
construction discharges that are in excess of the peak pre -construction 1 year discharge. The
release rates from the stormwater management facilities must be designed based on the above
evaluation to prevent additional stream bed or bank erosion. The above designs must be approved
in writing by the Division before any of the facilities tributary to each of the stormweer control
devices is occupied or opened for use, and the facilities (as approved by the Division), must be
constructed and operational;
12. The Piedmont Triad Airport Authority shall conduct its activities in a manner consistent with State
water quality standards (including any requirements resulting from compliance with section 303(d) of
the Clean Water Act) and any other appropriate requirements of State law and federal law. If the
Division determines that such standards or laws are not being met (including the failure to sustain a
designated or achieved use) or that State or federal law is being violated, or that further conditions are
necessary to assure compliance, the Division may reevaluate and modify this Certification to include
conditions appropriate to assure compliance with such standards and requirements in accordance with
15A NCAC 250507(d). Before modifying the Certification, the Division shall notify PTAA and the
US Army Corps of Engineers, provide public notice in accordance with 15A NCAC 250503 and
provide opportunity for public hearing in accordance with 15A NCAC 250504. Any new or revised
conditions shall be provided to PTAA m writing, shall be provided to the United States Array Carps
of Engineers for reference in any Permit issued pursuant to Section 404 of the Clean Water Act, and
shall also become conditions of the 404 Permit for the project;
13. Measures shall be taken to prevent live or fresh concrete from coming into contact with waters of the

PART H MONITORING, CONTROLS, AND LIMITATIONS FOR
PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources. which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain the following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map); showing the facility's location in relation to transportation routes
and surface -waters, the name of the receiving water(s) to which the stormwater
outfall(s) discharges, or if the dischas-ge
is to a municipal separate storm sewer
system, the name of the municipality"and the ultimate receiving waters, and
accurate latitude and longitude of the point(s) of discharge. The general location
map (or alternatively the site map) shall identify whether each receiving water is
impaired (on the state's 303(d) list of impaired waters) or is located in a
watershed for which a TMDL has been established, and what the parameter(s)
of concern are. .
(b) A narrative description of storage practices, loading and unloading activities,
outdoor process areas, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on-site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BUTs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the. facility
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
Part H Page 1 of 13

Permit No. NCS000508
accordance with the requirements found. in Part III, Standard Conditions, Section
B, Paragraph 3. The permittee shall re -certify annually that the stormwater
outfalls 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 cif 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 Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such tanks, and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices.(which shall be secured
closed with a locking mechanism), and 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, prior to release of the accumulated
stormwater. Accumulated stormwater shall be released if found to be
uncontaminated by any material. Records documenting the individual making the
observation, the description of the accumulated stormwater, and the date and time
of the release shall be kept for a period of five years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. -.The Spill Prevention and Response Plan,(SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing
Part II Page 2 of 13

Permit No. NCS000508
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 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
SPkP.
4. Preventative Maintenance and Good Housekeeping Program. A preventative
maintenance and good housekeeping program shall be developed. The program shall list
all siormwater 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 Pollution 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 written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summery of the Stormwater Management Plan.
Part II Page 3 of 13

Permit No. NCS000508
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 III, Standard Conditions, Section B, Paragraph 3) to the Director that the changes
have been made.
8.. Facility Inspections. Inspections of the facility and all koirmwater 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 t -
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
required in Part II B and C of this permit.
9. Implementation. The permittee shall implement the Plan. Implementation of the Plan
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 BMP9 associated with the industrial activities, ;ncluding.
vehicle maintenance activities. Such documentation shall be kept on-site fbii period of
five years and made available to the Director or the Director's authorized representative
immediately upon request.

If: The first valid sampling results are above a benchmark value, or outside of the benchmark range, for any
parameter at any outfall or in -stream location;
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. Identify potential source controls, operational controls, or physical improvements, if any, that could
reduce the difference between the sampling results and the benchmark value and select any such
corrective measure or combination of corrective measures that the permittee determines to be
appropriate and warranted, after due consideration of the cause and nature of the exceedance and the
feasibility, cost and effectiveness of -such measures.
4. Implement the selected actions, if any, within two months of the inspection, or as soon thereafter
as reasonably possible.
5. Recoid each instance of a Tier One response in the Stormwater Pollution Prevention Plan. Include
the date and value of the benchmark exceedance, the inspection date, the personnel conducting the
inspection, the selected actions, if any, and the date the selected actions were implemented, or, if no
action was implemented, the basis for that decision.
Tier Two
If: During the term of this permit, the first valid sampling results from two consecutive monitoring periods are
above the benchmark values, or outside of the benchmark range, for any specific parameter at a specific
outfall or in -stream location;
Then: The permittee shall:
1. Repeat all the required actions outlined above in Tier One.
2. Immediately institute monthly monitoring for each parameter at each 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 the 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. Maintain a record of the Tier Two response in the Stormwater Pollution Prevention Plan.
During the term of this permit, 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 or
in -stream location on four occasions, the permittee shall notify the DWQ Regional Office Supervisor in
writing within 30 days of receipt of the fourth analytical results.
The permittee -will then consult with DWQ about feasible, practical, and cost-effective measures that the
permittee could undertake to reduce the difference between the sampling results and the benchmark value and
to avoid causing or contributing to any violation of water quality standards. After consultation with the
permittee, DWQ may require that the permittee revise, increase, or decrease the monitoring frequency for the
remainder of the permit and may impose such other requirements, if any, as may be necessary to prevent the
Part II Page 9 of 13

Permit No. NCS000508
permittee's discharge from causing or contributing to any violation of water quality standards, including but
not limited to:
• require the permittee to install structural controls; or
• require the permittee to implement other stormwater control measures.
If the inspection and evaluation of a particular sampling result under Tier One or Tier Two show that the
result is not caused by the permittee's operations or facilities, it will not be treated as a benchmark
exceedance for purposes of determining whether four consecutive exceedances have -occurred.
This site discharges to a segment of the East Fork Deep River with an approved Total Maximum
Daily Load (TMDL) for turbidity and fecal coliform. The Division will consider monitoring
results in determining whether additional BMPs are needed to control the pollutant(s) of concern
to the maximum extent practicable.
If additional BMPs are needed to achieve the required level of control as mandated by the
TMDL, if any, the permittee will. be required to (1) develop a strategy for implementing
appropriate BMPs, and (2) submit' a timetable for incorporation of those BMPs into the permitted
Stormwater Pollution Prevention Plan.
SECTION C: QUALITATIVE MONITORING REQUIREMENTS
Qualitative monitoring requires a visual inspection of each stormwater outfall regardless of
representative outfall status and shall be performed as specified in Table 5, during the analytical
monitoring event. Qualitative monitoring is for the purpose of evaluating the effectiveness of the
Stormwater Pollution Prevention Plan (SPPP) and assessing new sources of stOrinwater pollution.
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 will be maintained with the SPPP.
