and/or wastewater discharges will end up in? Un-named Tributary of the Waccamaw
To find the waterbody, please see the "MAPS" tab on hftp://portal.ncdenr.org/weblw-(Lfor a map of NC
Surface Waterbody Classifications.
Receiving water classification(s) for the waters:
If the site will discharge to a separate storm sewer system, name the operator of the separate storm sewer
system (e.g. City of Raleigh municipal storm sewer).
Discharge of wastewater to receiving waters classified as WS-11 through WS-V, or SA, must be
approved by the Division of Water Resources (DWR) or Division of Marine Fisheries
(DMF). DEIVILR cannot grant coverage under NCGO20000 without that approval. Also be advised that no
new discharges of wastewater are permitted in receiving waters classified as WS-1 or freshwater
ORW. Wastewater discharges to saltwater ORW will not be approved under General Permit NCG02 but may
be eligible for an Individual permit.

fndieate Which of the Following Apply:
A. Preliminary Determination
® There appear to be waters on the above described project arealproperty, that may be subject to Section 404 of the Clean Water
Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters have been
delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. The approximate boundaries
of these waters are shown on the enclosed delineation map dated 12/5/2017. Therefore this preliminary jurisdiction determination
maybe used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of
impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a
preliminary JU will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they
are jurisdictional waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program
Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved ID, which is an appealable
action, by contacting the Corps district for further instruction.
❑ There appear to be waters on the above described project area/property, that may be subject to Section 404 of the Clean Water
Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). however, since the waters
have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process.
Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWAIRHA
jurisdiction over all of the waters at the project area, which is not sufficiently accurate and reliable to support an enforceable
permit decision. We recommend that you have the waters on your project area/prop" delineated. As the Corps may not be able
to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can
be verified by the Corps.
B. Approved Determination
❑ There are Navigable Waters of the United States within the above described project area/property subject to the permit
requirements of Section 10 of the Rivers and harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act
(CWAX33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for
a period not to exceed five years from the date of this notification.
❑ There are waters an the above described project arealproperty subject to the permit requirements of Section 404 of Clean
Water Act (CWA) (33 USC § 1344). UnIm there is a change in the iaw or our published regulations, this determination may be
relied upon for a period not to exceed five years from the date of this notification.
❑ We recommend you have the waters on your project arWproperty delineated. As the Corps may not be able to accomplish
this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by
the Corps.

❑ The waters on your project arealproperty have been delineated and the delineation has been verified by the Corps. The
approximate boundaries of these waters are shown on the enclosed delineation map dated 7/17/2017, If you wish to have the
delineation surveyed, the Corps can review and verify the survey upon completion. Once verified, this survey will provide an
accurate depiction of all areas subject to CWA and/or RHA jurisdiction on your property which, provided there is no change in
the law or our published regulations, may be relied upon for a period not to exceed five years.
❑ The waters have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official
identified below on SURVEY SIGNED DATE. Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.
❑ Thcre are no waters of the U.S., to include wetlands, present on the above described project area/property which are subject to the
permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is it change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.
® The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA).
You should contact the Division of Coastal Management in in Wilmington, NC, at [phone] to determine their

MONITORING OF WETLAND AREAS
Sediment discharge sampling per General Permit No. NCG020000
Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic
of the volume and nature of the permitted discharge. Analytical sampling shall be
performed during a measurable storm event. Samples shall be taken on a day and time
that is characteristic of the discharge. All samples shall be taken before the discharge
joins or is diluted by any other waste stream, body of water, or substance. Monitoring
points as specified in this General Permit shall not be changed without notification to
and approval of the Permit Issuing Authority [40 CFR 122.410)j.
Record in Results
For each measurement or sample taken pursuant to the requirements of this
General Permit, the permittee shall record the following information [40 CFR
122.41 ]:
• The date, exact place, and time of sampling or measurements;
• The individual(s) who performed the sampling or measurements;
• The date(s) analyses were performed;
• The individual(s) who performed the analyses;
• The analytical techniques or methods used; and
• The results of such analyses.
Flow Measurements
Where required, appropriate flow measurement devices and methods
consistent with accepted scientific practices shall be selected and used

to ensure the accuracy and reliability of measurements of the volume of
monitored discharges.
Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC regulations
published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting
Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the
Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136.
To meet the intent of the monitoring required by this General Permit, all test procedures
must produce minimum detection and reporting levels and all data generated must be
reported down to the minimum detection or lower reporting level of the procedure_ If no
approved methods are determined capable of achieving minimum detection and
reporting levels below the General Permit discharge requirements, then the most
sensitive (method with the lowest possible detection and reporting level) approved
method must be used.
Representative Outfall
If a facility has multiple discharge locations with substantially identical stormwater
discharges that are required to be sampled, the permittee may petition the Director for
representative outfall status. If it is established that the stormwater discharges are
substantially identical and the permittee is granted representative outfall status, then
analytical sampling requirements may be performed at a reduced number of outfalls.
Records Retention
Visual monitoring shall be documented and records maintained at the facility along with
the Stormwater Pollution Prevention Plan (SPPP). Copies of analytical monitoring
results shall also be maintained on -site or be available electronically to a DEMLR
inspector upon request. The permittee shall retain records of all monitoring information,
including
• All calibration and maintenance records
• All original strip chart recordings for continuous monitoring instrumentation
• Copies of all reports required by this General Permit, including Discharge
Monitoring Reports (DMRs) and eDMR or other electronic DMR report
submissions
• Copies of all data used to complete the Notice of Intent to be covered by this
General Permit
These records or copies shall be maintained for a period of at least 5 years from the
date of the sample, measurement, report or Notice of Intent application. This period may
be extended by request of the Director at any time [40 CFR 122.411.
Inspection and Entry
The permittee shall allow the Director, or an authorized representative (including an
authorized contractor acting as a representative of the Director), or in the case of a
facility which discharges through a municipal separate storm sewer system, an
authorized representative of a municipal operator or the separate storm sewer system

receiving the discharge, upon the presentation of credentials and other documents as
may be required by law, to:
• Enter upon the permittee's premises where a regulated facility or
activity is located or conducted, or where records must be kept under
the conditions of this General Permit;
• Have access to and copy, at reasonable times, any records that must
be kept under the conditions of this General Permit;
• Inspect at reasonable times any facilities, equipment (including
monitoring and control equipment), practices, or operations regulated
or required under this General Permit; and
• Sample or monitor at reasonable times, for the purposes of assuring
permit compliance or as otherwise authorized by the Clean Water
Act, any substances or parameters at any location [40 CFR
122,41(i)].
Discharge Monitoring Reports
Samples analyzed in accordance with the terms of this General Permit shall be
recorded on Discharge Monitoring Report (DMR) forms provided by the Director or
submitted electronically to the appropriate authority using an approved electronic DMR
reporting system (e.g., eDMR). Annual Summary DMRs shall be delivered to the
Division (Central Office) no later than March 1 of each year (See 2. of this section).
In addition, any samples analyzed in accordance with the terms of this permit that
violate a wastewater effluent limit or exceed a stormwater benchmark value shall be
submitted to the Division Regional Office on a DMR form and delivered to the Division
Central Files no later than 30 days from the date the facility receives the sampling
results from the laboratory. DMR forms are available on the Division's website
(http://portal.ncdenr.orglweb/lr/npdes-stormwater). Regardless of the submission
method (paper or electronic), submittals shall be delivered to the Division, or
appropriate authority, according to the provisions above.
When no discharge has occurred from the facility during the report period, the permittee
is required to submit a discharge monitoring report, within 30 days of the end of the
specified sampling period, giving all required information and indicating "NO FLOW" as
per NCAC T15A 02B .0506.
If the permittee monitors any pollutant more frequently than required by this General
Permit using test procedures approved under 40 CFR Part 136 and at a sampling
location specified in this General Permit or other appropriate instrument governing the
discharge, the results of such monitoring shall be included in the data submitted on the
DMR.
The permittee shall record the required qualitative monitoring observations on the SDO
Qualitative Monitoring Report form provided by the Division and shall retain the
completed forms on site. Qualitative monitoring results should not be submitted to the
Division, except upon DEMLR's specific requirement to do so. Qualitative Monitoring
Report forms are available at the website above.

Submitting Reports
Two signed copies of the Annual Summary Discharge Monitoring Report (DMR) shall be
submitted no later than March 1 of each year to DWR Central Files CUot DEMLR):
Central Files
Division of Water Resources
(DWR) 1617 Mail Service
Center
Raleigh, North Carolina 27699-1617
If wastewater monitoring results indicate a wastewater effluent limit violation, a
signed DMR form for that monitoring period shall be sent to the appropriate DEMLR
Regional Office (Attn: Stormwater Permitting Program) no later than 30 days from the
date the facility receives the sampling results from the laboratory.
If stormwater monitoring results indicate a stormwater benchmark value exceedance
or the facility is in Tier 2 monitoring, a signed DMR form for that monitoring period
shall be sent to the appropriate DEMLR Regional Office (Attn: Stormwater Permitting
Program) no later than 30 days from the date the facility receives the sampling
results from the laboratory. All stormwater outfall parameters shall be monitored and
reported for any monitoring period that the facility is following a Tier 2 response.
Addresses for each RO and the counties covered by each RO can be found here:
http://portal.ncdenr.org/web/guest/regional-offices. The permittee shall retain the
completed originals on site. Visual (Qualitative) monitoring results should not be
submitted to the Division unless specifically requested.
Blank DMR forms, Annual Summary DMR forms, and visual monitoring forms are
available at the website of the Division's Stormwater Permitting Program:
http://portal.ncdenr.org/web/lrinpdes-stormwater
The Permit Issuing Authority may require the permittee to begin reporting monitoring
data electronically during the term of this permit. The permittee may be required to use
North Carolina's eDMR internet application for that purpose. Until such time that the
state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting
Regulation (CROMERR), permittees will be required to submit all discharge monitoring
data to the state electronically using eDMR and will be required to complete the eDMR

submission by printing, signing, and submitting one signed original and a copy of the
computer printed eDMR to the address above,
