the subject project on May 17, 2021. The Division is hereby notifying you that permit SW8 110611 has been renewed
on May 26, 2021, and shall be effective until September 16, 2029. For your records, please find enclosed a renewed,
updated, and re -issued permit and a copy of the renewal application. Please keep this permit on file at all times. Please
note that the renewed, updated, and re -issued permit does not impose new or different terms; it merely restates some of
the previous terms to provide you with a better understanding of your obligations under the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the
terms and conditions of this state stormwater permit. The plans originally approved on September 16, 2011 and most
recently modified on October 13, 2017, will remain in full force and effect in accordance with the regulations set forth

adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written
petition must conform to Chapter 150B of the North Carolina General Statutes and must be filed with the OAH within
thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding the filing fee (if a
filing fee is required) and/or the details of the filing process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or
via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made this permit
shall be final and binding.

STATE STORMWATER MANAGEMENT PERMIT
OVERALL LOW DENSITY WITH AREAS OF HIGHER DENSITY
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
Commanding Officer US MCB Camp Lejeune
Mobile MOUT Training Area
Range Road, Camp Lejeune, Onslow County
FOR THE
construction, operation and maintenance of an overall 12% low density project with three (3)
infiltration basins and one (1) wet detention pond to treat the areas of higher density, within '/z mile of
and draining to SA waters, in compliance with the provisions of 15A NCAC 2H .1000 and Session Law
2008-211 (the "stormwater rules') the approved stormwater management plans and specifications
and other supporting data as attached and on file with and approved by the Division of Energy,
Mineral and Land Resources (the "Division" or "DEMLR") and considered an enforceable part of this
permit.
The facilities shall be constructed, operated and maintained in accordance with the conditions of this
permit, the approved plans and specifications, and other supporting data attached to and on file with
the Division. This permit shall be effective from the date of issuance until September 16, 2029, and
shall be subject to the following specified conditions and limitations:
I. DESIGN STANDARDS
1. This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Sections 1.9, 1.10 and 1.11 of this permit. The stormwater controls labeled BMP 1,
BMP 2, BMP 3 and BMP 4 are designed to handle the runoff from 193,072 ft2, 67,082 ftZ,
33,977 ft2 and 26,572 ft2, respectively, of impervious area.
3. The overall project shall be maintained at or below a maximum density level of 12%. The
project is a "mobile" training area, meaning that the built -upon area will be relocated within the
project area as training demands. The maximum allowable amount of built -upon area for the
entire 1,038 acre project area is 5,425,834 square feet. With this modified permit, a total of
1,347,932 sf of impervious area is permitted. Of this amount, 1,197,034 sf is existing
previously permitted BUA prior to consolidation; 34,823 sf was added with the February 2012
modification; and, 116,075 sf is proposed new BUA for P1479. A total of 4,077,902 sf of
impervious area is available for future development.
4. The P1479 project utilizes sheet flow and vegetated conveyances to convey runoff to a level
spreader (Subbasin DA's 3, 4, 9, 10 & 14) which has been designed to handle the peak flow
from the 1 inch per hour storm and to achieve diffuse flow.

A 50' wide vegetative buffer must be provided adjacent surface waters, measured horizontally
from and perpendicular to the normal pool of impounded structures, the top of bank of both
sides of streams and rivers and the mean high water line of tidal waters.
For each permitted BMP, the runoff in excess of the design storm must flow overland through
a 50' vegetated filter designed to pass the peak flow from the 10 year storm in a non -erosive
manner.
The overall tract and each drainage area will be limited to the amount of built -upon area
indicated in Sections 1.2, 1.3, 1.9, 1. 10, and 1.11 of this permit, and per approved plans.
The runoff from all built -upon area within the permitted drainage area(s) of this project must be
directed into the permitted stormwater control system.

I Level Spreader -Vegetated Filter Strip / Restored Riparian Buffer Maintenance Requirements I
Important maintenance procedures:
Immediately after the filter strip is established, any newly planted vegetation will be watered twice weekly if
needed until the plants become established (commonly six weeks).
Once a year, the filter strip will be reseeded to maintain a dense growth of vegetation
Stable groundcover will be maintained in the drainage area to reduce the sediment load to the vegetation.
Two to three times a year, grass filter strips will be mowed and the clippings harvested to promote the growth of
thick vegetation with optimum pollutant removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches
and may be allowed to grow as tall as 12 inches depending on aesthetic requirements (NIPC, 1993). Forested
filter strips do not require this type of maintenance.
Once a year, the soil will be aerated if necessary.
- Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inch
(or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
® does ❑ does not incorporate a vegetated filter at the outlet.
This system (check one):
® does ❑ does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall

Filter Strip, Restored Riparian Buffer and Level Spreader
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
Iog in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

STORMWATER MANAGEMENT PERMIT APPLICATION FORM
LOW DENSITY SUPPLEMENT
This form may be photocopied for use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can be
found in Session Law 2008-211, 15A NCAC 2H .1000, Session Law 2006-246, and the DWQ BMP Manual.
Curb and gutter systems are allowed provided they meet the requirements in 15A NCAC 2H .1008(g).
