Per our conversations in October 2014, and on behalf of the Piedmont Triad Airport Authority
Message (PTAA), notice of intent to use Nationwide Permit 13 and General Water Quality Certification
Text: (WQC) 3885 pursuant to Sections 404 and 401 of the Clean Water Act (CWA) and 15A NCAC 2H
.0500 is hereby provided for unavoidable impacts to a stormwater discharge channel and Jordan
buffer at the Piedmont Triad International Airport (PTIA). The impacts are necessary to repair
failed stormwater management infrastructure and stabilize erosion potentially contributing to
turbidity benchmark exceedances observed under the PTIA National Pollutant Discharge

Elimination System ( NPDES) Permit (NCS000508). Six locations (Sites #1 through #6) were
identified in need of repair or stabilization (Drawing PL -1, attached) in the Brush Creek sub -
basin. Site #1 is collapsed pipe, slope failure, and erosion at NPDES Stormwater Discharge
Outfall (SDO) 023, discharging to an unnamed tributary to Brush Creek (Drawing GL -1); Site #2 is
a collapsed concrete channel discharging to Brush Creek (Drawing GL -2); Site #3 is significantly
eroded channel downstream from SDO 030 (Drawing GL- 3A -3E); Site #4 is eroded outfall at SDO
033 (Drawing GL -4); Site #5 is sinkhole and slope failure upstream from an unmonitored SDO
(Drawing GL -5); and Site #6 is a section of failed riprap channel (Drawing GL -6).
Approximately 5,984 square feet Jordan Buffer at Site #1 (Drawing SB -1) and Site #2 (Drawing
SB -2), currently existing as eroding slope / failed stormwater management infrastructure, will be
impacted by repairing the facilities, re- grading, and re- vegetating to restore ground cover to match
adjacent topography.
Approximately 364 linear feet of stormwater discharge channel banks (Site #3, Drawings SB -3.1-
3.3) are proposed to be stabilized using natural channel design principals to the extent
practical. This discharge channel is not depicted on the USGS 7.5' Topographic quadrangle or
the NRCS Guilford County Soil Survey (maps attached), but has eroded a deep ravine since the
SDO was constructed.
Temporary construction impacts will be minimized through implementation of a stringent erosion
control schedule and the use of Best Management Practices (BMPs). The contractor will be
required to follow contract specifications pertaining to erosion control measures as outlined in the
attached drawings. Prior to the commencement of construction, a Sedimentation and Erosion
Control Plan for the project will be submitted to NCDENR and PTAA will obtain a Sedimentation
and Erosion Control Permit and accompanying NPDES Construction Permit, as
needed. Potential impacts to surface water quality from the stormwater infrastructure repairs will
be effectively mitigated through adherence to the approved Sedimentation and Erosion Control
Plan. The applicant will adhere to applicable criteria of USACE Nationwide Permit 13, USACE
Nationwide Permit General Conditions, Final Regional Conditions for Nationwide Permits in the
Wilmington District, and DWR General Certification Conditions for WQC #3885. The PCN and
supporting information will be mailed to USACE (1 copy) and DWR (4 copies, including fee). The
PTAA and I appreciate your consideration of this request. Please feel free to contact me at your
convenience with any questions /comments.

Impact Justification and Mitigation
1.
Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Stream impacts are specifically for purposes of stabilization using natural channel design criteria. Buffer impacts are unavoidable due to outfall
locations near stream origins. Existing buffer conditions will be improved by stabilizing currently eroded slopes and re- vegetating.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Construction - related impacts will be avoided and minimized to the extent possible by applying DEMLR- approved sedimentation and erosion control
protocols as noted on construction plans.
2.

THICKNESS: 6 INCHES MINIMUM
WIDTH: 12 FOOT MINIMUM OR FULL WIDTH AT ALL POINTS
OF THE VEHICULAR ENTRANCE & EXIT AREA;
WHICHEVER IS GREATER.
LENGTH: 50 FOOT MINIMUM
3. LOCATION: LOCATE CONSTRUCTION ENTRANCES & EXITS TO LIMIT SEDIMENT FROM
LEAVING THE SITE & TO PROVIDE FOR MAXIMUM UTILITY BY ALL CONSTRUCTION
VEHICLES.
4. AVOID STEEP GRADES & ENTRANCES AT CURVES.
5. NO SEPARATE MEASUREMENT OR PAYMENT WILL BE MADE FOR THIS ITEM.
6. INSPECT THE SURFACE & TOP DRESS THE SURFACE AS NEEDED WITH GRAVEL.

EROSION CONTROL CONSTRUCTION
SEQUENCE NOTES:
GENERAL
THE CONTRACTOR SHALL SUBMIT TO THE ENGINEER AND OWNER A DETAILED CONSTRUCTION PROGRESS SCHEDULE. THESE PLANS
AND SPECIFICATIONS PROVIDE GENERAL CONSTRUCTION SEQUENCE AND SAFETY PARAMETERS WHICH MUST BE INCORPORATED INTO
THE APPROVED SCHEDULE. THE CONTRACTOR'S APPROVED EROSION CONTROL PLAN SHALL BE INCORPORATED INTO THE
CONSTRUCTION SEQUENCE PLAN.
THE CONSTRUCTION OF THE PROJECT MUST BE COMPLETED IN SEQUENTIAL ORDER AS LISTED BELOW:
* MOBILIZATION
* EROSION CONTROL
* CONSTRUCT WORK ELEMENTS
* SEEDING AND MULCHING
PLANNED TEMPORARY EROSION CONTROL FEATURES
1. TEMPORARY CONSTRUCTION ENTRANCE PAD
2. DROP INLET PROTECTION
3. EROSION CONTROL MATTING
ALL DISTURBED AREAS ARE TO BE SEEDED AND MULCHED IN ACCORDANCE WITH ITEMS T -901 AND T -908 OF THE
SPECIFICATIONS, WITHIN 14 DAYS FOLLOWING COMPLETION OF ANY PHASE OF GRADING. PERMANENT GROUND COVER SHALL BE
OBTAINED WITHIN 15 WORK DAYS OR 90 CALENDAR DAYS (WHICHEVER IS SHORTER) FOLLOWING COMPLETION OF THE PROJECT.
ANY FINES, PENALTIES, OR OTHER COSTS ASSESSED BY STATE, LOCAL OR THE GOVERNMENTAL AGENCIES FOR
NON— PERFORMANCE OF THE EROSION CONTROL REQUIREMENTS OF THIS PROJECT AGAINST THE OWNER SHALL BECOME THE
RESPONSIBILITY OF THE CONTRACTOR, AND ANY SUCH ASSESSMENTS, IF NOT PAID BY THE CONTRACTOR, WILL BE DEDUCTED
FROM MONIES DUE AT THE COMPLETION OF THIS PROJECT.
PHASING
1. ATTEND PRECONSTRUCTION CONFERENCE
2. INSTALL EROSION CONTROL MEASURES
3. PERFORM CONSTRUCTION OPERATIONS
4. SEED AND MULCH ANY DISTURBED AREAS
5. ONCE PERMANENT SEEDING HAS BEEN ESTABLISHED, REMOVE ALL TEMPORARY EROSION CONTROL FEATURES. SEED AND
MULCH THE AREAS EFFECTED BY THE REMOVAL
MAINTENANCE PLAN
1. ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR STABILITY AND OPERATION FOLLOWING EVERY
RUNOFF — PRODUCING RAINFALL BUT IN NO CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS WILL BE MADE
IMMEDIATELY TO MAINTAIN ALL PRACTICES AS DESIGNED.
2. SEDIMENT WILL BE REMOVED FROM BEHIND THE SILT FENCE OR INLET PROTECTION WHEN IT BECOMES ABOUT 0.5 FT.
DEEP. THE EROSION CONTROL BARRIER WILL BE REPAIRED AS NECESSARY TO MAINTAIN A BARRIER.
3. THE ENGINEER MAY DIRECT THAT ADDITIONAL SILT FENCING OR INLET PROTECTION BE INSTALLED AT ANY TIME PRIOR TO
FINAL ACCEPTANCE.
