Orange Water and Sewer
Please find attached the Pre -Construction Notification (PCN) Application for the above referenced
project. The Orange Water and Sewer Authority (OWASA) is proposing to modify the existing water
line and stabilize the streambanks. Modification of the water line consists of removing the in -stream
portion thereof, abandoning the portion of the water line beyond the stream, and installing a new line.
The new water line will be buried for the majority of the length with a short section being supported on
the substructure of the Lake Ellen Drive bridge over the stream, an unnamed tributary to Booker Creek.
Bank stabilization work is proposed to include removal of the existing riprap, repairing areas damaged by
erosion, and installing an imbricated stone wall along the stream bank.
Replacement of the water line and repair of the bank stabilization measures require encroachment in one
intermittent stream. Proposed impacts include 32 feet of temporary impacts associated with the bank
stabilization and 15 feet of temporary impacts associated with dewatering for construction access. The
stream is an unnamed tributary to Booker Creek.
If you would like to schedule a site visit, have any questions, or require additional information, please
contact me at 919.863.9350. Thank you for your assistance.
Sincerely,
Ms. Keven Arrance
Principal Scientist

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The site consists of an undeveloped area adjacent to Lake Ellen and Lake Ellen Drive. The site includes a reach of an
unnamed tributary to Booker Creek, an intermittent stream. Adjacent properties consist of single-family residential
development on wooded lots.
3b. List the total estimated acreage of all existing wetlands on the property:
0 - None present.
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
75 feet
3d. Explain the purpose of the proposed project:
The OWASA utility line is currently protected by riprap that was previously placed in the bed of the stream. Erosion of the
riprap protection is occurring, leaving the pipe vulnerable to damage. The proposed project involves stabilization of the
stream bank and modification of the water line. Proposed bank stabilization measures consist of rock cascades on each
bank. The water line will be relocated to the Lake Ellen Drive bridge over the UT to Booker Creek. The water line is
proposed to be installed below the roadway deck but above the bottom of the roadway support beams. Placing the water
line on the bridge structure will prevent the pipe from exposure to stream flow. The existing pipe will be removed from the
stream bed.
3e. Describe the overall project in detail, including the type of equipment to be used:
The existing water line will be removed where it is within the stream channel and to a point five feet landward of top of
bank. The remaining segments of the water line within the project limits will be abandoned in place. The proposed water
line will be installed adjacent to and under existing roadways and mounted on the substructure of the existing bridge over
the UT to Booker Creek.
The existing riprap within the channel and along the banks will be removed. An imbricated stone wall will be constructed
along the banks, extending approximately 3 feet below the elevation of the stream bed to four feet above the stream bed
elevation. The proposed stone shall be placed within the footprint of the existing riprap. A pump -around system with
coffer dams and a filter bag will be utilized during in -stream work to establish and maintain a dry work area and to
minimize transport of sediment downstream of the work area.
Disturbed areas will be graded to near existing elevations, except where repair of erosion damage is proposed. The
disturbed areas will be reseeded and/or replanted, as appropriate, for permanent stabilization while retaining the required
10 -foot wide utility maintenance corridor and roadway right-of-way safety. Equipment that is expected to be used to
perform the proposed work may include, but is not limited to, a backhoe, front end loader, temporary pump -around
system, excavator, dump truck, flat-bed truck, and paving equipment.

topographic quadrangle or the USDA Soil Survey of Orange County, North Carolina (1977). The channel was constructed as
a spillway for Lake Ellen.
D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Avoidance of all impacts is possibly only with the no -action alternative. The no -action alternative leaves the existing pipe at
risk of damage and potential failure. The pipe is proposed to be elevated out of the stream, reducing the volume of non -
natural material in the channel. Bank stabilization measures have been designed to be the minimum necessary to protect the
stream channel from future erosion damage.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Coffer dams and a pump -around system will be utilized to establish and maintain dry work conditions for in -stream work. A
filter bag will be part of the pump -around system to minimize sedimentation downstream of the work area. Work will be
performed from non jurisdictional areas to the extent feasible in order to minimize impacts to waters of the US. Erosion and
sediment control measures, including silt fence and Best Management Practices, will be implemented and maintained for the
duration of construction acitivities.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State

Endangered species identified via IPaC for the project area include dwarf wedgemussel, Michaux's sumac (historic), and
smooth coneflower (historic). Visual assessment of the stream reach within the project area was performed, and the
USFWS Dwarf Wedge Mussel Recovery Plan was reviewed. No population of dwarf wedgemussel has been identified
within the Cape Fear River Basin, and the habitat conditions in the stream within the project area are not conducive to
supporting a popoulation of dwarf wedgemussel. The two endangered plants are thought to be extirpated from Orange
County. Soil requirements for each species are not met by the mapped soil unit within and surrounding the project area.

SELF INSPECTION REQUIREMENTS
THE SEDIMENTATION POLLUTION CONTROL ACT WAS AMENDED IN 2006 TO REQUIRE
THAT PERSONS RESPONSIBLE FOR LAND -DISTURBING ACTIVITIES INSPECT A PROJECT
AFTER EACH PHASE OF THE PROJECT TO MAKE SURE THAT THE APPROVED EROSION
AND SEDIMENTATION CONTROL PLAN IS BEING FOLLOWED. RULES DETAILING THE
DOCUMENTATION OF THESE INSPECTIONS TOOK EFFECT OCTOBER 1, 2010. THE
SELF -INSPECTION PROGRAM IS SEPARATE FROM THE WEEKLY SELF-MONITORING
PROGRAM OF THE NPDES STORMWATER PERMIT FOR CONSTRUCTION ACTIVITIES. THE
FOCUS OF THE SELF -INSPECTION REPORT IS THE INSTALLATION AND MAINTENANCE
OF EROSION AND SEDIMENTATION CONTROL MEASURES ACCORDING TO THE
APPROVED PLAN. THE INSPECTIONS MUST BE CONDUCTED AFTER EACH PHASE OF THE
PROJECT, AND CONTINUED UNTIL PERMANENT GROUND COVER IS ESTABLISHED IN
ACCORDANCE WITH NCGS 113A-54.1 AND 15A NCAC 4B.0131. THE SELF -INSPECTION
REPORT FORM IS AVAILABLE AS AN EXCEL SPREADSHEET FROM:
HTTP://WWW.DLR.ENR.STATE.NC.US/PAGES/SEDIMENTATION_NEW.HTML

2. TOPSOIL SHALL BE PLACED IN AREAS TO BE SEEDED AND ROUGHENED WITH
TRACKED EQUIPMENT OR OTHER SUITABLE MEASURES. SLOPES STEEPER THAN
3:1 MAY BE ROUGHENED BY GROOVING, FURROWING, TRACKING, OR STAIRSTEP
