Subject Property: Northwest Regional Water Reclamation Facility
Approval of 401 Water Quality Certification with Additional Conditions
Dear Ms. Navarrete:
You have our approval, in accordance with the attached conditions and those listed below to temporarily impact
0.03 acres of jurisdictional wetlands and 105 linear feet of temporary impacts to an intermittent stream for the
installation of a sewer force main for the Northwest Regional Water Reclamation Facility, as described within
your 401 Preconstruction Notification (PCN) application dated September 9, 2010 and received by the
Wilmington Regional office (WiRO) on September 13, 2010 and additional information received on October 20,
2010, November 1, 2010, December 13, 2010, December 22, 2010 and December 23, 2010. After reviewing your
application, it has been determined that the impacts are covered by General Water Quality Certification Number
3819 (GC 3819). This Certification allows you to use Nationwide Permit 12 (NW 12) when issued by the US
Army Corps of Engineers (USACE). In addition, you should obtain or otherwise comply with any other
required federal, state or local permits before you go ahead with your project including (but not limited to)
Erosion and Sediment Control, Non-discharge, and stormwater regulations. Also, this approval to proceed with
your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon
expiration of the 404.
This approval is for the purpose and design that you described in your application. If you change your project,
you must notify us and you may be required to send us a new application. If the property is sold, the new owner
must be given a copy of this Certification and approval letter and is thereby responsible for complying with all
conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of
stream, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). This approval
requires you to follow the conditions listed in the attached certification and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific and general conditions of
this Certification (or Isolated Wetland Permit) are met. No other impacts are approved including
incidental impacts:

2. Sedimentation and Erosion Control
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 in order to
protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated, and
maintained in accordance with the most recent version of the North Carolina Sediment and Erosion
Control Planning and Design Manual.
b. The 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.
c. 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.
d. The reclamation measures and implementation must comply with the reclamation in accordance with
the requirements of the Sedimentation Pollution Control Act.
3. No Waste, Spoil, Solids, or Fill of Any Kind
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. 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.
4. No Sediment & Erosion Control Measures within Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters to the maximurn extent
practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable,
they shall be removed and the natural grade restored within six months of the date that the Division of
Land Resources has released the project.
5. Temporary Wetland Impacts
Restoration of the areas to be temporarily impacted needs to have the soils separated into the different layers.
When placing the soils back into the trench, do it in the reverse order of how it was excavated (the hydric soil
and organics need to be placed on top - first excavated needs to be the last soils to be put in trench).

6. Construction Stormwater Permit NCG010000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources
(DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater
permit (NCG010000) administered by DWQ is automatically issued to the project. This General Permit
allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions
in the permit. If your project is covered by this permit [applicable to construction projects that disturb one
(1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-
monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring
report forms may be found at htW://h2o.enr.state.ne.us/su/Fornzs Documents. him. Copy enclosed.
Please notify this Office immediately if any turbidity issues arise.

Onslow Water and Sewer Authority shall require its contractors (and/or agents) to comply with all of
the terms of this Certification, and shall provide each of its contractors (and/or agents) a copy of this
Certification. A copy of this Certification shall be included in the construction contract and available on the

are necessary to assure compliance, DWQ 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, DWQ shall notify Onslow Water and Sewer Authority and
