Subject: EXEMPTION from Stormwater Management Permit Regulations
Fort Fisher Recreational Area Drinking Water System Repair -Utility Project
Stormwater Project No. SW8120409
New Hanover County
Dear Mr. Bero:
Dee Freeman
Secretary
The Wilmington Regional Office of the Division of Water Quality received a copy of the Soil and Erosion Control Plan for the
subject utility project on April 16, 2012. Staff has reviewed the application for the applicability of the Stormwater Management
rules to this project Based on our review, you do not appear to be proposing development activities on this site at this point in
time that would be subject to the stormwater requirements as provided for in 15A NCAC 2H.1000. However, be advised that
other regulations will potentially apply to your proposed activities.
In accordance with 15A NCAC 26.0231 and Division policy, new or continued ditching activities after March 1,1999, may be a
violation of state wetland standards. !Violation of tiiase standards may result in r the assessment of cMi penalties and other
requirements to bring the project into compliance without additional wetlands impacts. In addition to the wetland standards, if
your protect disturbs one acre or more and has a int source discharge of stormwater runoff, then it is also subject to the
National Pollutant Discharge Elimination System rNPDES) stormwater discharge requirements. You are required to have an
NPDES permit for stormwater discharge from projects meeting these criteria. Any temporary built -upon area associated with the
construction of the project must be removed within 30 days of completing the project, or when it is no longer needed, whichever
occurs first.
If at any time in the future, development of any part of this site is planned, as defined in NCAC 21-1.1000, or you do not develop
the project in'the manner indicated in the application,. you must apply for and receive a Stormwater Management Permit prior to
construction. If you have any questions concerning this matter, please do not hesitate to call Linda Lewis at [phone] or
email her at [e-mail].
Sincerely,
For Charier kt� Dire for

Re: Fort Fisher Recreational Area — Repair Non -Compliant Drinking Water System
Dear Ms. Lewis,
Attached please find plans and project narrative for the replacement of approximately 8,000
linear feet of new waterline and senlices at the Fort Fisher Rec eational Area. This project is a
simple replacement project and no new buildings, roads, or other built -upon -area is proposed as
part of the project. After the waterline has been installed, the surface will be restored to that of
existing conditions.
Please confirm that no additional stormwater permitting will be required as part of this project.
We are currently seeking a land disturbance permit, but are not aware of any others that would be
required for this type of utility work.
If you have any questions or concerns about this plan submittal, please do not hesitate to give me
a call at [phone] or email at [e-mail]. We look forward to working
with you to complete this project.
Best Regards,

Fort Fisher, NC
Sediment and Erosion Control Narrative
Project Description
This project is located at the Fort Fisher Recreational Area at Ft. Fisher, NC. Through various studies it
has been determined that the existing drinking water system is currently experiencing water quality
issues. This water system was constructed in two parts: an older cast iron piping system from the 1950's
and a newer PVC water system from the late 1970's. Seymour Johnson Air Force Base has decided to
abandon in place the cast iron piping system and replace it with new PVC water mains and services. This
project includes the installation of approximately 4,700 linear feet of new water main and 3,375 linear
feet of new water services for the existing buildings.
No new built upon area is proposed as part of this project. All new waterlines will be installed and the
surface will be restored to that of existing conditions. Asphalt and concrete pavement will be installed to
replace that removed in parking areas, drive aisles, and sidewalks. All areas in open space will be seeded
upon completion of waterline installation.
Sediment and Erosion Control Measures
All erosion control practices for the site have been designed in accordance with the requirements of the
NCDENR Sediment and Erosion Control Design Manual.
To help control sediment laden runoff from leaving the project area, silt fence will installed on the
downside of all waterline trenches. In addition, all nearby storm drainage inlets will receive inlet
protection to further protect the existing storm drainage network and downstream surface waters.
As the proposed waterline is being installed, previous areas of installed waterline will be restored to that
of existing conditions. It is the intent of this project to not have more than 1 acre of land disturbance at
any one time. It is anticipated that this number should be much less. All disturbed areas are to be
stabilized with ground cover as soon as practicable but in any event within 14 calendar days from the last
land -disturbing activity.

SEQUENCE OF CONSTRUCTION
1. A LAND DISTURBANCE PRE -CONSTRUCTION MEETING IS REQUIRED PRIOR TO ANY DISTURBANCE ONSITE. INVITE THE LOCAL NCDENR
INSPECTOR, OWNER, OWNER'S ENGINEER, AND GRADING CONTRACTOR. SCHEDULE THE MEETING AT LEAST 48 HOURS PRIOR TO THE
PRE -CONSTRUCTION MEETING AND LAND DISTURBANCE. NOTIFY LOCAL NCDENR REGIONAL OFFICE PRIOR TO ANY LAND DISTURBANCE.
2. INSTALL TREE PROTECTION FENCE AS INDICATED ON THE PLANS DISTURBING ONLY THE AREA NECESSARY FOR THE INSTALLATION OF THE
FENCE.
3. INSTALL SILT FENCE FOR CONTRACTOR LAYDOWN AREA. SILT FENCE IS TO ENCIRCLE ENTIRE CONTRACTOR LAYDOWN AREA.
4. CONTRACTOR TO FOLLOW DAILY CONSTRUCTION SEQUENCE BELOW FOR ALL WATERLINE INSTALLATION PROCEDURES. ONLY THE AREA IN
WHICH THE WATERLINE CAN BE INSTALLED AND SURFACE STABILIZED EACH DAY SHOULD BE DISTURBED.
DAILY CONSTRUCTION SEQUENCE
4.1. IDENTIFY THE LINEAR FOOTAGE OF WATERLINE THAT CAN BE INSTALLED FOR EACH DAY OF WORK. DETERMINE IF RAIN IS EXPECTED
FOR THAT DAY'S WORK.
4.2, IF RAIN IS EXPECTED ON CURRENT DAYS WORK, INSTALL SILT FENCE IN WORK AREA AS INDICATED ON THE PLANS DISTURBING ONLY
THE AREA NECESSARY FOR THE INSTALLATION OF THE FENCE. INSTALL INLET PROTECTION ALSO AS INDICATED ON THE PLANS.
4.3. OPEN CUT ANY AREAS OF ASPHALT OR SIDEWALK NEEDED FOR WATERLINE INSTALLATION.
4.4. EXCAVATE TRENCH AND INSTALL WATERLINE. ALL EXCAVATED MATERIAL SHOULD BE PLACED ON THE HIGH SIDE NEXT TO THE OPEN
TRENCH. CONNECT ALL TEES, VALVES, FIRE HYDRANTS, ETC AS SHOWN ON THE UTILITY PLANS PREPARED BY OTHERS.
4.5. UPON COMPLETION OF THE WATERLINE INSTALLATION, BACKFILL AND COMPACT TRENCH. IN AREAS WHERE CONCRETE OR PAVEMENT
IS TO BE REPLACED, SELECT GRANULAR FILL IS TO BE USED AS BACKFILL MATERIAL UNTIL PAVING OPERATIONS OCCUR. STABILIZE
OPEN SPACE AREAS WITH PERMANENT SEED AND MULCH.
4.6. CONTACT ON -SITE SUPERINTENDENT TO APPROVE SITE STABILIZATION MEASURES. SWEEP ANY PAVEMENT OR CONCRETE WITHIN
THE WORK AREAS THAT MAY CONTAIN EXCESS SEED OR SEDIMENT.
4.7. AFTER APPROVAL FROM ON -SITE SUPERINTENDENT, REMOVE EROSION CONTROL MEASURES FROM PROJECT AREA.
5. ONCE ALL SITE IMPROVEMENTS ARE COMPLETED, FINE GRADE AND STABILIZE ANY REMAINING DISTURBED AREAS WITH SEED AND MULCH.
ALL SEEDING SHOULD BE COMPARABLE TO THAT OF EXISTING GROWTH. AREAS THAT ARE IN PAVEMENT SECTIONS THAT HAVE BEEN
PREVIOUSLY PROVIDED WITH SELECT GRANULAR FILL ARE TO BE COMPACTED TO THE REQUIRED DENSITY AND PAVED OVER WITH
MATERIAL AND SECTION SPECIFIED ON PLANS BY OTHERS. CONTRACTOR TO INSPECT AREAS PREVIOUSLY STABILIZED WITH SEED AND
MULCH AND ENSURE A VEGETATIVE COVER. ANY AREAS WITHIN CONSTRUCTION LIMITS THAT DO NOT HAVE VEGETATIVE COVER ARE TO
HAVE ADDITIONAL SEED AND MULCH SPREAD.
6. CONTACT LOCAL NCDENR EROSION CONTROL INSPECTOR FOR SITE CLOSEOUT. AFTER ALL SITE WORK IS APPROVED BY THE NCDENR
INSPECTOR, REMOVE ANY REMAINING EROSION CONTROL MEASURES AND STABILIZE ANY AREAS REQUIRING ADDITIONAL PERMANENT
STABILIZATION WITHIN PROJECT AREA.
IMPORTANT NOTE: EXISTING CONDITION INFORMATION PROVIDED BY OTHERS
AND IS NOT THE RESULT OF A SURVEY BY THE TIMMONS GROUP. NO
WARRANTY IS GIVEN OR IMPLIED REGARDING THE ACCURACY OF THE FEATURES
