Subject: Stormwater Permit No. SW8 010431 Modification
Bachelor Enlisted Quarters Jackson Street
High Density Project
Onslow County
Dear Mr. Paul
The Wilmington Regional Office received a complete, modified Express Stormwater
Management Permit Application for Bachelor Enlisted Quarters Jackson Street on October 11,
2013. Staff review of the plans and specifications has determined that the project, as proposed,
will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are
forwarding modified Permit No. SW8 010431 dated October 25, 2013, for the construction,
operation and maintenance of the built -upon areas and BMP's associated with the subject
project.
Effective August 1, 2013 the State Stormwater program has been transferred from the Division
of Water Quality (DWQ) to the Division of Energy, Mineral and Land Resources (DEMLR). All
previous references to DWQ will remain in older stormwater permits issued prior to August 1,
2013 until they are modified. Please note that the updated pages in this permit now reference
DEMLR as the Division responsible for issuance of the permit
The modifications covered by this permit include the addition of 753 square feet of new built -
upon area to DA-1 for the purpose of adding a boiler building as part of the Base -wide steam
decentralization project P-1449. An analysis of the existing infiltration basin #1 shows that there
is sufficient capacity to accept the additional runoff without enlarging the basin. No changes are
proposed to Basin #2. This modification is approved as a minor modification under the 2008
rules. The approved plan sheets showing the location, grading and size of the P-1449 boiler
building addition are to be added to the previously approved plans.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacts any
development approval issued by the Division of Water Quality under Article 21 of Chapter 143 of
the General Statutes, which is current and valid at any point between January 1, 2008, and
December 31, 2010. The law extends the effective period of any stormwater permit that is set to
expire during this time frame to three (3) years from its current expiration date. On August 2,
2010, the Governor signed Session Law 2010-177, which grants an extra year for a total of four
(4) years extension.
Accordingly, this permit, which was set to expire on January 10, 2015, shall now be effective
from the date of issuance until January 10. 2019,which includes all available extensions, and
shall be subject to the conditions and limitations as specified therein. Please pay special
attention to the conditions listed in this permit regarding the Operation and Maintenance of the
BMP(s), recordation of deed restrictions, certification of the BMP's, procedures for changing
ownership, transferring the permit, and renewing the permit. Failure to establish an adequate
system for operation and maintenance of the stormwater management system, to record deed
restrictions, to certify the BMP's, to transfer the permit, or to renew the permit, will result in
future compliance problems.

Cc: Towler GS03 David
Subject: SW8 010431 Minor Mod.
Carolina:
I want to apologize up front. I'm not sure how this occurred, but for this particular modification, the original 1.5"
minimum design volume in the permit somehow got mixed up with and labeled as the provided volume in the
basin (14,486 cubic feet). It was not meant to imply that 14,486 was the minimum volume required. However,
based on the old calculation sheets in the file, it is understandable how you came to that conclusion.
I always rerun and check the numbers, and when I did, I discovered that the minimum required 1.5" volume is
14,127 cubic feet. I'll check it again later just to be sure. For whatever reason (probably user error — mine!) the
provided volume somehow also got reported as the minimum required volume. In reality, it appears that no
change to the existing infiltration basin elevation is required because the new total required volume that I
calculate is 14,345 cubic feet, still less than the current provided volume of 14,486 cubic feet.
Please let me know how you would like to handle. Do you want to continue with the proposed changes? If we
do that, future changes may be easier to do since there will be excess volume in the basin. Or do you want to
provide revised calculations for the minimum required 1.5" volume and keep the current basin as is?

Stormwater Management Narrative BB147A
PREPARED FOR: NAVFAC Mid-Atlantic/USMC NC IPT
PREPARED BY: Carolina Matiz, P.E.
COPIES: File
DATE: August 6, 2013
PROJECT NUMBER: 460598
PERMIT NUMBER: SW8 010431
The project proposes the construction of one equipment building (BB147A) located behind the
existing Bachelors Enlisted Quarters. The 18' x 30' building and 5'x7' transformer pad will be
placed to ensure that the stormwater runoff generated by the new structures will drain into the
existing Pond #1 and ultimately to the bioretention pond.
The stormwater runoff will sheet flow over grassed areas prior to being collected in the infiltration
basin.
The original stormwater management system was designed to retain and treat the runoff generated
by a 1.5" rainfall event. The runoff from larger storm events is bypassed at the smart weir control
structure and discharged to the Courthouse Bay. The system was enhanced in 2005 by adding two
bioretention ponds. A decanting structure was added at the infiltration ponds to drawdown the
system at a faster rate and discharge into the bioretention areas. The stormwater runoff generated
by the new structures was calculated using the 1-year-24 hour storm event (3.65 inches from the
NOAA database) in accordance with the direction received at the June 12, 2013 scoping meeting.
In order to provide treatment for the additional runoff, the decant structure in Pond 1 will be raised
0.48 inches. No other changes or modifications to the existing system are proposed with this Permit
Modification. The stormwater management system will continue to operate as currently permitted.
The C value for drainage area 1 was recalculated and is 0.64. It was originally permitted as C=0.63.
The orifice size for the decanting structure is still valid. The volume left after 5 days would be 641
cf, from the original permit, plus the added 218 cf from the new structures, for a total depth in Pond
#1 of 859cf/6572 sf = 0.13 ft.
Erosion and sediment control measures will be implemented during the construction phase to
ensure no sediment laden is discharged from the project area.

Stormwater Management Narrative BB147A
PREPARED FOR: NAVFAC Mid -Atlantic/ USMC NC 1PT
PREPARED BY: Carolina Matiz, P.E.
COPIES: File
DATE: August 6, 2013
PROJECT NUMBER: 460598
PERMIT NUMBER: SW8 010431
The project proposes the construction of one equipment building (BB147A) located behind the
ti _ezisngLBachel6rs Enlisted ' Quarters. Xl7cd J8' x 30' building and 5'x7' transformer pad will be
rplaced to ensure thatithe stormwater runoff; generated by the new structures will drain into the
exishng Poridj#1 and ultimately to the bioretention pond.
The stormwater runoff will .sheetflow.. over' grassed areas prior to being collected in the infiltration
basin.
The original stormwater management system was designed to retain and treat the runoff generated
by a 1.5" rainfall event. The runoff from larger storm events is bypassed at the smart weir control
structure and discharged to the Courthouse Bay. The system was enhanced in 2005 by adding two
bioretention ponds. A decanting structure was added at the infiltration ponds to drawdown the
system at a faster rate and discharge into the bioretention areas. The stormwater runoff generated
by the new structures was calculated using the 1,year-24 hour storm event (3.65 inches from the
NOAA database) in accordance with the direction received at the June 12, 2013 scoping meeting.
In order to provide treatment for the additional runoff, the decant structure in Pond 1 will be raised
0.48 inches. No other changes or modifications to the existing system are proposed with this Permit
Modification. The stormwater management system will continue to operate as currently permitted.
The C value for drainage area 1 was recalculated and is 0.64. It was originally permitted as C=0.63.
The orifice size for the decanting structure is still valid. The volume left after 5 days would be 641
cf, from the original permit, plus the added 218 cf from the new structures, for a total depth in Pond
#1 of 859cf/6572 sf = 0.13 ft.
Erosion and sediment control measures will be implemented during the construction phase Jo
ensure no sediment laden is discharged from the project area.
