Subject: Application for NPDES Stormwater Permit
Piedmont Triad International Airport
Dear Mr. Elmore:
It has been some time since we have had any further discussions about the NPDES Stormwater
Permit for the Piedmont Triad International Airport (PTIA). Our discussions in April, 2002, had
indicated that we would have seen the permit application that summer. We do need to move
forward with obtaining the application and processing of the individual NPDES Stormwater Permit
for PTIA. We would like to have the application submitted to us within the next 60 days if
possible. Our staff will begin review and permit drafting once a complete application is submitted.
Please keep in mind that while PTIA made application as a part of a group application back in
1992, this airport will need to submit the Form 1 and Form 2F individual application to us along
with the appropriate fee, in order for us to move forward with drafting and issuing the permit. The
operation of major industrial activities such as the FEDEX hub should not begin until the NPDES
permit is issued for the entire PTIA operation. As we had discussed, the construction activity
stormwater discharges will be covered under our General Permit NCGO10000 and your approved
erosion and sedimentation control plan, but the operational activities will be covered in an
individual NPDES permit.
If you have any questions or need further information, please contact me at 733-5083 ext 525.
Sincerely yours,
Bradley Bennett, Supervisor

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 (DWQ) Regulations in 15
NCAC 211, 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 5L/23R, Proposed New Overnight Express
Air Cargo Sorting and Distribution Facility, and Associated Developments at Piedmont 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:
Sediment and Erosion Control:
Sediment and erosion control measures shall adhere to the design standards for sensitive
watersheds [15A NCAC 4B .0024]; 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;
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

grade shall be re-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;
Wetland and Stream Miti ag tion:
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 LawGibb Group/MACTEC
(December 28, 2001). 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 Is' of each year for the entire length of the five year
monitoring period;

requirements approved by the Water Quality Committee of the Environmental Management
Commission on October 9, 2002 are hereby incorporated as conditions of this 401 Certification;
3

Stormwater Mana eg ment:
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 5L/23R, and
8d. Crossfield taxiway.
8e. Within one 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 1, 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 Higgins for Brush Creek and downstream to Lake
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 contamination 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;
d

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 Lake 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 stormwater control
devices is occupied or opened for use, and the facilities (as approved by the Division), must be
constructed and operational;
Continuing Compliance:
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 2H.0507(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 2H.0503 and
provide opportunity for public hearing in accordance with 15A NCAC 2H.0504. Any new or revised
conditions shall be provided to PTAA in writing, shall be provided to the United States Army Corps
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;
Other conditions:
13. Measures shall be taken to prevent live or fresh concrete from coming into contact with waters of the
state until the concrete has hardened;
14. Waste or borrow sites shall not be located in streams or wetlands;
15. All mechanized equipment operated near surface waters must be regularly inspected and maintained
to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids and other toxic
materials;
16. All work in stream channels shall be performed during low flow conditions;
17. The outside edge of the buffer, wetland or water boundary, along the entire construction corridor
within the boundaries approved under this Certification shall be clearly marked by orange fabric
fencing for areas that have been approved to infringe within the buffer, wetland or water prior to
any land disturbing activities;
18. All temporary fill and culverts shall be removed and the impacted area returned to the original
grade, including each stream's original cross sectional dimensions, plan form pattern, and
longitudinal bed and bed profile after construction is complete or within six (6) months of the
establishment of the crossing, whichever is sooner, and the various sites shall be stabilized with
natural woody vegetation (except for the maintenance areas of permanent utility crossings) and
restored to prevent erosion. If the crossings are not completely removed and restored as described
above within the specified time above, additional written approval from the Division must be
obtained to modify this condition;

19. In the event that PTAA undertakes to transfer property ownership of any land containing retained
jurisdictional wetlands, waters and protective buffers, deed notifications or similar mechanisms
shall be placed on all said jurisdictional areas on the property in order to assure compliance for
future wetland, water and buffer impact. These mechanisms shall be put in place prior to said
property transfer. A sample deed notification can be downloaded from the 401[Wetlands Unit web
site at h2o.enr.state.nc.us/ncwetlands;
20. The anticipated cumulative impacts from this project shall be addressed via written agreements
between the NC Division of Water Quality, Greensboro and Guilford County in accordance with
the appropriate signed agreements;
21. Violations of any condition herein set forth may result in revocation of this Certification and may
result in criminal and/or civil penalties;
22. Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate
of Completion" form to notify the Division when all work included in the §401 Certification has
been completed. The responsible party shall complete the attached form and return it to the
401/Wetlands Unit of the NC Division of Water Quality upon completion of the project.
Photographs upstream and downstream of each culvert site must be included to document correct
installation along with the Certificate of Completion form;
23. This Certification shall expire upon expiration of the 404 Permit.
If this Certification is unacceptable to you, you have the right to an adjudicatory hearing upon written request
within sixty (60) days following receipt of this Certification. This request must be in the form of a written petition

Scope of Work
Preparation of an NYU" Applicatlon
for the Piedmont Triad international Airport
August 2001
Scope of Work
At a meeting held on I Jane 2000, the North Carolina Department of Environment and
Natural Resources (NCDENR) notified the Piedmont Triad Airport Anthority (PTAA)
that it must apply for and obtain an individual industrial National Pollutant Discharge
Elimination System (NPDES) permit_ Baker and Associates (Baker) proposes to
complete the following items of work in order for PTAA to submit a completed
application for an individual industrial NPDES permit:
1. Attend an initial kickoff meeting with the NCDENR to approve this scope and
schedule
2. Prepare and complete EPA Form 3S IO-1 known as Application Form 1 — General
Information
3. Prepare and complete EPA Form 2F — Application for Permit to Discharge
Stormwater Discharges Associated with Industrial Activity.
Preparation of .Form 21F includes
a. Inventory and re -verification of existing outfalis within airport property
currently there are approximately 50 outfalls surrounding the airport)
b. Update of the Spill Prevention Control and Countermeasure Plan (SPCCP) for the
latest inventory of on site stored material
c. Assist the PTAA in preparing agreements with tenants as co-permittees for the
application_ Composition of agreements and final execution of the agreements
with tenants is the responsibility of the PTAA
d. Update existing site drainage plan
e_ Investigate and compose a narrative of the past three years of material inventory
that has been stored and or disposed of that may have been exposed to stormwater
discharge points
f_ Inventory of the storm water discharges through dye testing or smoke testing to
verify the inlet locations and identify any floor drains or points of entry that are
not specifically designated as stormwawr collection facilities
g. Compose a report of a history of spills for the past three years

l
h, Develop a sampling program of all existing outfalls for industrial type parameters
including items such as pH, flow, oil and grease, nitrates, total suspended solids
and other constituents as mandated by NCDENR. Baker will work with the
NCDENR to identify and prepare a sampling program to meet the testing
requirements in accordance with the listing of pollutants required for to be tested
if the pollutant is expected to be present - tables 2F-3 and 2F-4 as defined on the
NPDES application form. See attachment A for a summary of the current permit
sampling requirements at Raleigh Durham Airport and Charlotte. Baker
anticipatcs the final pertnit sampling will be similar for PTAA
The sampling program will define methods and procedures to collect grab
samples for the first thirty minutes of a designated storm event. Sampling can
occur only during a rain event. Rain is an unscheduled event. All samples are to
be collected from a storm event greater than 0_ l inch
j. ) :valuate the entire stormwater system and prepare a consolidated outfall plan in
order to reduce the number of potential sampling locations to a manageable and
representative number ( Baker recommends that the PTAA consider consolidating
the existing outfalls to reduce the potentially permitted outfalls from
approximately 50 to potentially less than 10)
k. Baker will sub -contract with a local laboratory to perform and prepare reports for
the necessary sampling to assist in completing item 3.1.8 and 3.1_9 above
1. Assist the sub -contract laboratory in collection of samples
m. Submit the application and address comments from the NCDENR
n. Attend coordination meetings with the PTAA and NCDENR during the
application process, including attendance at a public hearing if required by the
NCDENR
o. This scope of work is complete with the issuance of an individual permit from the
NCDI~NR. Future sampling. testing and completion of Discharge Monitoring
Reports are not included in this scope of work.

Purpose:
This meeting was scheduled to discuss the National Pollutant Discharge Elimination System
permitting process.
Summnry of Meeting:
Due to the current size and potential growth of the Piedmont Triad International Airport (PTIA),
the North Carolina Department of Environment and Natural Resources, Division of Water
Quality (DENR) has determined that the PTIA is required to submit an application to attain an
individual National Pollutant Discharge Elimination System (NPDES) Permit. This permit is in
accordance with the Phase I NPDES regulations.
DENR provided background of the NPDES process. The PTIA, along with numerous other
airports in North Carolina, is operating under a permit application filed by the AAAE in 1995.
The Charlotte and Raleigh-Durhain airports are the only two airports in the state that operate
under an individual permit. These two individual permits may serve the PTIA as a guideline for a
final permit. These individual permits contain monitoring and reporting requirements of a
number of constituents and parameters such as flow, total suspended solids, toxicity and glycol.
The DENR may not require specific limits for the majority of the constituents. The frequency of
the sampling may vary from quarterly to annually. Laboratory testing may be required in the
permit. The DENR can provide the PTIA a listing of certified laboratories. The permit will be in
the name of the PTIA. It is suggested that the PTIA tenants be co-permitees with the ultimate
responsible party remaining PTIA.

Meeting Minutes
Piedmont Triad International Airport
National Pollutant Discharge Elimination System Permit
The DENR has determined that the PTIA fits in the industrial category of stormwater discharge.
The DENR provided the PTIA with a copy of Application Form 1— General Information and
Form 2F — Application for Permit to Discharge Stormwater — Discharges Associated with
Industrial Activity. Components of the Application are the implementation of a Spill Prevention
Plan and a comprehensive Stormwater Management Plan. The PTIA currently has a Spill
Prevention Control and Countermeasure Plan and a comprehensive Stormwater Management Plan
under final review. The completion of these documents places the PTIA ahead in the application
process.
The PTIA asked the question if the granting of an individual NPDES permit has any connection
to the current EIS and or the 401/404 permitting process. The DENR response is that this
individual permit is not connected to the EIS and the 401/404 processes, This individual NPDES
permit is a separate process.
The City of Greensboro is operating under a General Permit and has ongoing monitoring
procedures and sampling results. The DENR suggested that the PTIA contact the City of
Greensboro to discuss procedures and sampling results.
The application process is as follows:
• PTIA complete application
• DENR review and comment period
• Public notification of a pending NPDES permit
• A public hearing ( if determined to be necessary by the DENR Director)
• Granting of the individual permit
A submittal date was not set for the application. The PTIA will submit a proposed application
preparation schedule to the DENR for review and approval.

Resolution Adopting Randleman Lake Storm Water Management Plan
WHEREAS, under 15A NCAC 213; 0251 of the North Carolina Code of Regulations, local
governments having land in the Randleman Lake Watershed, including the Authority, must
adopt a comprehensive storm water management plan, that is approved by the North Carolina
Environmental Management Commission, for the portion of their jurisdiction that is within
the watershed boundary and;
WHEREAS, the staff of the Authority has developed a proposed plan in accordance with the
state regulations entitled A Storm Water Plan for the Deep River (Randleman Lake)
Watersheds @ (the AProposed Plan@), a copy of which has been furnished to each of the
members of the Authority, and such plan has been approved on behalf of the North Carolina
Environmental Management Commission by its Water Quality Committee; and
WHEREAS, the adoption and implementation of the Proposed Plan would fulfill the
Authority's obligations under the applicable regulations, would promote good watershed
management of the portion of the Randleman Lake Watershed that is within the Authority's
jurisdiction, and would help to improve water quality within the Randleman Lake Watershed
and the Randleman Lake Reservoir now under construction;
NOW, THEREFORE, BE IT RESOLVED by the Piedmont Triad Airport Authority that the
Proposed Plan is hereby approved and adopted as the Randleman Lake Storm Water
Management Plan of the Authority in accordance with 15A NCAC 2B. 0251 and that the
officers and staff of the Authority are hereby directed to Implement such plan in accordance
with its terms.
August, 2001 Section 7 Resolution Randleman Lake

7.0 Storm Water Plan for Deep River (Randleman Lake) Watershed
Under 15A NCAC 2B. 0251 (4), local governments with land use authority within the
proposed Randleman Lake Watershed are required to adopt comprehensive storm water
management plans for the portion of the watershed that is under their jurisdiction. The Deep
River, High Point Watershed, as described in this SWMP, and as shown on the Watershed
Map that appears at the end of this Section, is a part of the larger Randleman Lake
Watershed, and PTAA is therefore required by 15A NCAC 2B.0251(4) to adopt a
comprehensive storm water plan for the portion of the Airport that is within this area. This
Section 7 sets forth the plan the PTAA has adopted. It is intended as a supplement to the rest
of this SWMP, and applies only to land within the Deep River, High Point Watershed that
PTAA presently owns or acquires in the future.
The regulations describe six separate components to be included in the plan. The applicable
requirements of the regulations, and the corresponding provisions of PTAA's plan, are as
follows:
Evaluation of Existing Land Use
Regulation:
(a) Evaluation of existing land use within Oak Hollow Lake subwatershed, High Point
Lake subwatershed and Deep Riverl subwatershed in the Randleman Lake Watershed
with recommendations that show how overall built -upon area (for existing and future
development) for each subwatershed can be minimized and high intensity land uses
can be targeted away from surface waters and sensitive areas. Oak Hollow Lake
subwatershed is defined as all land areas draining to Oak Hollow Lake. High Point
Lake subwatershed is defined as all land areas draining to High Point Lake, East Fork
Deep River and West Fork Deep River from Oak Hollow Lake Dam. Deep River 1
subwatershed is defined as all land areas draining to the Deep River from High Point
Lake Dam to Freeman Mill Dam. This evaluation shall be done by the local
governments having jurisdiction in those watersheds, working in cooperation with the
PTRWA.
Goal:
Evaluate and possibly modify existing land use plans and development patterns to
achieve better protection of the Randleman Lake Watershed.
August, 2001 Section 7-Page 1 Randleman Lake

Action Items:
The Watershed Map appearing at the end of this Section identifies three separate
zones within the Deep River, (Randleman Lake) Watershed, for planning purposes, as
follows:
■ Zone 1: Zone 1 consists of the Runway Protection Zone (RPZ) in the approach to
existing Runway 5R, as shown on the map, plus some adjoining land outside of
the RPZ. PTAA owns most of the land within Zone 1 as shown on the map. The
land that is owned by PTAA within Zone 1 is presently undeveloped, except for
an instrument landing system, other navigational aids, and a gravel service road.
■ Zone 2: Zone 2 consists of all of the land that is owned by PTAA within the
Randleman Lake Watershed that is not within Zone 1 or Zone 3. Zone 2 includes
major airport facilities, including a portion of Runway 14-32 and associated
taxiways, an air cargo building and major aircraft hangars. PTAA is presently
relocating its Maintenance Building within Zone 2.
■ Zone 3: Zone 3 is located at the southwest end of proposed Runway 5L-23R. It
will consist of the portion of the RPZ for the proposed runway north of the right-
of-way of U.S. 421 and east of the right-of-way for U.S. 68, plus some additional
land adjacent to the RPZ. PTAA now owns a portion of the land within Zone 3
and may acquire additional land within Zone 3 in the future. At present, Zone 3
contains extensive commercial and light industrial development. The Watershed
Map shows the boundaries of Zone 3 based on the RPZ and runway location that
is currently proposed by the PTAA. If the location of the RPZ changes in the
final design of the runway, Zone 3, as referred to in this Plan, will coincide with
the revised RPZ plus the adjacent land shown on the Map.
There are three water bodies within the Airport portion of the Randleman Lake
Watershed as shown on the U.S.G.S. Topographic Map ("Guilford, N.C." revised
1994) for the area: (1) a stream along the southeast boundary of Zone 1, (2) a pond on
the northwest side of Zone 3 and (3) a stream, also within Zone 3, below the pond.
These streams are ephemeral.
PTAA's plan for meeting the requirements of this portion of the Randleman Lake
Regulations is as follows:
1. PTAA's goal is to direct future development within its portion of the Randleman
Lake Watershed primarily to Zone 2.
2. PTAA plans to demolish a portion of the existing development within Zone 2, in
the vicinity of the proposed runway, as well as a portion of the existing
development within Zone 3, including warehouses and adjacent parking areas
August, 2001 Section 7-Page 2 Randleman Lake

within those zones. As a result of this demolition, approximately 20 acres of
existing Built Upon Area will actually be removed and will be replaced with
natural ground cover.
3. The only new development that is currently planed by PTAA within Zone 1 is an
upgrade of the instrument approach to Runway 5R. If PTAA decides in the future
to undertake any other development within Zone 1, it will comply with FAA
restrictions that apply to the Runway Protection Zone (RPZ) in the approach to
the runway. (The limits of the RPZ are shown on the Watershed Map.) These
restrictions prohibit residential development, places of public assemblage, and
fuel storage facilities from being relocated within an RPZ.
4. Subject to the issuance by the FAA of a favorable Record of Decision and to the
satisfaction of certain other conditions, PTAA presently plans to construct a
proposed Runway 5R-23L and to establish the RPZ for the new runway. If the
new runway is constructed, the only development currently planned by PTAA
within its portion of Zone 3 is the installation of an instrument approach system
for the new runway, other navigational aids, and a service road. If PTAA decides
in the future to undertake any other development within Zone 3, PTAA will
comply with the FAA restrictions on development within the new RPZ; and
PTAA will also maintain on Object Free Area, 800 feet wide, running the entire
length of the runway and extending 1000 feet beyond the runway end. Additional
Object Free Areas will be required for each taxiway. Although there are no
current plans for doing so, PTAA may in the future extend the new runway to the
southwest, but in such case the Object Free Area and RPZ for the runway would
also be extended in that direction.
This plan applies only to land that is owned by the PTAA within Zones 1 — 3 and not
to any land that is owned by other parties. If PTAA acquires additional land within
Zones 1 —3 in the future, the additional land will become subject to this plan at the
time of its acquisition.
The foregoing plan will not only minimize Built Upon Area within the Watershed,
but will actually reduce Built Upon Area, in and around Zone 3, by approximately 20
acres. By establishing a goal of concentrating new development primarily in Zone 2,
the plan will also target high intensity land uses away form surface waters and
sensitive areas because the only water bodies within PTAA's portion of the
Watershed are located in Zones 1 and 3.
In carrying out the foregoing plan, PTAA will cooperate with the PTRWA by
attending the annual update meetings for which it receives notice or is otherwise
aware among the PTRWA and the local government units having territory within the
Randleman Lake Watershed.
August, 2001 Section 7-Page 3 Randleman Lake

Coordinated Planning Efforts
Regulation:
(b) Coordination between all affected jurisdictions to encourage their development in the
existing urban areas. The planning effort shall include provisions for areas of
contiguous open space to be protected through conservation easements or other long-
term protection measures and provisions to direct infrastructure growth towards
existing urban development corridors rather than to rural lands.
Goal:
To achieve greater watershed protection and efficiency through regional coordination
among the jurisdictions in the Randleman Lake Watershed.
Action Items:
PTAA's goal of locating new development primarily in Zone 2, will help to
concentrate development in the areas in which it already exists and to divert
development away from the open space that is owned by PTAA within Zone 1 and
away from the area that will be restored to natural growth in Zone 3. Long-term
protection measures will be imposed for all of these areas by PTAA's maintenance of
the RPZ for the Runway 5R approach, by PTAA's establishment of an RPZ for the
Runway 5L approach, and by the creation of the Object Free Areas for the new
runway and taxiways, as described above. These protections will remain in effect for
as long as the runways are operational. These restrictions will help to protect the
open areas within Zones 1 and 3 and improve storm water quality within these Zones.
PTAA will cooperate with the other jurisdictions within the Randleman Lake
Watershed by attending the annual update meetings sponsored by the PTRWA, as
stated above. PTAA will also assist the efforts of adjoining jurisdictions to develop
land use plans that are compatible with airport development for areas outside the
Airport boundaries, including plans for the maintenance of open space, where
appropriate.
August, 2001 Section 7-Page 4 Randleman Lake

Evaluation of Existing Ordinances
Regulation:
(c) Evaluation of existing ordinances, municipal programs (maintenance, street cleaning,
etc.) and other local policies to identify opportunities for storm water quality
improvements including reducing the amount of built -upon area that is required for
uses such as parking, building set -backs, road widths and cul-de-sacs. The
evaluations shall consider development options such as multiple story buildings,
mixed use to encourage pedestrian travel and mass transit and an identification of
municipal activities and procedures that may be modified to allow for storm water
pollution prevention opportunities.
Goal:
To identify opportunities to fine tune existing ordinances and policies so as to achieve
better quality in the Randleman Lake Watershed.
Action Items:
PTAA is restricted in its ability to alter land use requirements by FAA development
standards, such as height and setback requirements, and by PTAA's obligation to
conform to Airport Layout Plan that is approved for the Airport by the FAA.
However, PTAA will attempt to achieve storm water quality improvements as
follows:
1. In undertaking new development projects within the Randleman Lake
Watershed, PTAA will investigate design alternatives that reduce new Built
Upon Area.
2. In grading areas within the Randleman Lake Watershed, PTAA will attempt to
control soil erosion and sedimentation by phasing grading operations, and by
accelerating the establishment new ground cover over graded areas, so as to
reduce the time that unprotected areas are exposed to erosion.
3. All new development projects that are undertaken by PTAA throughout the
Airport, including Zones 1 — 3, will comply with the watershed protection
requirements set forth in PTAA's Watershed Ordinance and this SWMP
unless a valid Variance is granted under the procedures set forth in the
Ordinance. Pursuant to the Watershed Ordinance, PTAA has elected to apply
high density criteria to all new development projects resulting in a new Built
Upon Area of more than five acres. This requirement is in excess of the state
minimum requirements because the Built Upon Percentage at the Airport is
less than 24%, and therefore PTAA could have elected to apply low -density
August, 2001 Section 7-Page 5 Randleman Lake

criteria to all new development at the Airport. As a result of the election made
by PTAA, engineered storm water controls will be required for all projects in
excess of the five -acre limit. The Watershed Ordinance also requires that new
development projects resulting in new Built Upon Area of five acres or less be
designed, to the maximum extent practicable, to minimize Built Upon Area, to
direct storm water runoff away from surface waters, and to incorporate Best
Management Practices to minimize water quality impacts. A Watershed
Protection Plan will be required for all new development projects (regardless
of size) showing how the applicable criteria will be met. These requirements
will greatly reduce the impact of any new development that does occur within
the Randleman Lake Watershed.
4. PTAA will implement a Spill Prevention Control and Countermeasure Plan
(SPCCP) that will establish procedures to help prevent, control and remediate
spills of oil or hazardous materials at the Airport.
Public Education Programs
Regulation:
(e) Implementation of watershed protection public education programs.
Goal:
To educate the community about impacts of storm water discharge on water bodies
and what is needed to reduce storm water pollution in the Randleman Lake
Watershed.
Action Items:
There is no population living within the portion of the Airport that leis within the
Randleman Lake Watershed. However, PTAA will undertake, through distribution of
this SWMP and PTAA's SPCCP, to educate Airport tenants concerning the impacts
of storm water discharge and the actions that are necessary to improve storm water
quality at the Airport. PTAA will also make a presentation to Airport tenants, upon
the final adoption of this SWMP, of the requirements of the plan and of the SPCCP,
and of the impact of storm water discharge on water quality. PTAA will also explore
the possibility of participating in a multi jurisdictional interlocal agreement to meet
the educational requirements of the Randleman Rules. The proposed interlocal
agreement would allow the communities to cooperate in the creation and
dissemination of educational material that would educate the community about the
effects of storm water pollution on our limited water resources.
August, 2001 Section 7-Page 6 Randleman Lake

Identification and Removal of Illegal Discharges
Regulation:
(e) Identification and removal of illegal discharges.
Goal:
To improve water quality through the identification and removal of illegal discharges
within the Randleman Lake Watershed.
Action Items:
Through the implementation of its SPCCP, PTAA will attempt to locate areas at the
Airport form which an illegal discharge might occur and to identify the storm water
outlet that would be affected.
PTAA also anticipates the issuance of an NPDES permit to PTAA, in which Airport
tenants will be named a co-permittees, with respect to storm water discharge at the
Airport. The permit is expected to require periodic monitoring of storm water outfalls
at the Airport for various substances, including oil and hazardous material.
If an illegal discharge is identified by PTAA on PTAA property within the
Randleman Lake Watershed, PTAA will attempt to determine the source. If PTAA's
own activities are the source of the discharge, the discharge will be discontinued. If
the discharge results from a source other than PTAA, such as a PTAA tenant, PTAA
shall take such reasonable actions as it shall determine; within its authority, to assist
in the removal of the discharge. PTAA will also include in all new lease agreements
that it enters into with its tenants a requirement that, upon discovery by the tenant or
the receipt of notification, the tenant will take such remedial actions as may be legally
required with respect to any illegal use or release of hazardous materials by the tenant
on PTAA property.
Identification of Potential Storm Water Retrofit Locations
Regulation:
(0 Identification of suitable locations for potential storm water retrofits (such as riparian
areas) that could be funded by various sources.
Goal:
To develop a process to identify and plan for storm water retrofits in the Randleman
Lake Watershed.
August, 2001 Section 7-Page 7 Randleman Lake

Action Items:
The removal of existing Built Upon Area from Zone 3 and surrounding land, as
described above, will result in the restoration of natural ground cover, including grass and
low shrub -type vegetation. (Tall growing trees will not be permitted within the RPZ in the
approach to Runway 5L). In grading the previously developed land, PTAA will develop a
series of meandering grass swales. A grass swale is noted by the NCDENR in its publication
of Best Management Practices as potentially removing up to 35% of Total Suspended Solids
(TSS). PTAA will also consider planing grass filter strips below any remaining impervious
surface to filter runoff from these areas. Filter strips are noted by the NCDENR as
potentially removing up to 40% of TSS.
