Dear Dr. Hauser
The Wilmington Regional Office received a complete, modified State Stormwater Management Permit
Application for the subject project on February 5, 2018. 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 effective January 1, 2017, We are forwarding modified Permit No. SWS 960424
dated Pebruai-v 23, 201 S, for the construction, operation and maintenance of the stormwater control
measures (SCMs), built -upon areas, as well as the stormwater collection system and/or vegetated
conveyance systern associated with the subject project. Please add the attached plans to the previously
approved plan set.
This permit shall be effective from the date of issuance until July 16, 2022 and shall be subject to the
conditions and limitations as specified therein, and does not supersede any other agency permit that: may
be required. Please pay special attention to the permit conditions regarding the operation and
maintenance of the SCMs, stormwater collection system, and/or vegetated conveyances; the limitation of
built -upon area; modification of the project; the procedures for changing ownership of and/or transferring
the permit, and the need to renew the permit. Please also pay attention to the permit conditions that
requires the recordation of deed restrictions and protective covenants, easements, and the maintenance
agreement, which must all be provided along with certification upon completion of the project. Failure to
comply with these requirements will result in future compliance problems.
The following modifications are included and covered by this permit: `
1. Drainage Area 5 (System 5 in Permit Text), A new shellfish mariculture demonstration center
will be constructed. This project adds 2,341 sf of impervious area treated with a cistern designed
per 15A NCAC 02H .1057. The concrete basins located in the buffer are necessary to bring
seawater into the system, and have therefore been determined to be water -dependent structures
which are allowed per.1003(4)(d)(h).
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an 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

Dear Kelly,
ECWFI V E
FEB 0 5 2010
This response is for the January 10, 2018 receipt of additional information requested for the above
referenced project and the items have been addressed as follows:
Clarifications:
Vat. Drainage Area: Please verify that the proposed system is a stand-alone system which will not
impact any of the currently -permitted drainage areas. (The 1994 approved plans are not clear
where the systems' drainage areas are located.)
This system is a stand-alone system and should not impact any of the currently permitted drainage
areas.
%K Sidewalk:
i. Please verity that the sidewalk shown on the plans is not being proposed with this
application. It appears that this application is only for a new rainwater harvesting
system to collect rainwaterfrom a new building.
The existing sidewalk is proposed to be removed and replaced with a wood sidewalk.
.47. The 1994 permitted plans do not appear to show the sidewalk on the proposed plan.
There are other areas on the site that also appear to be constructed differently than the
1994 plan as well. Please clarify how these items will be addressed.
The existing sidewalk is proposed to be removed and replaced with a wood sidewalk.
c. Project Name: The current permit as well as the current application show that the permit is to be
issued to "Carteret Community College", but the deed shows that "Carteret Technical College"
owns the land. Please cla f, why there is a discrepancy.
Please see the attached printout from the NC Secretary of State Corporation website. Carteret
'Technical College appears to be a previous legal name.

Rainwater 1larvesting: Please submit documentation that the proposed systeni will meet the three
requirements in l5A NCAC 02H.1057, which is attached for your reference. For .1057(4), please submit a
copy of the NCSU Rainwater Harvester Model data showing that the system will treat at least 85% of the
annual runoff.
See the attached NCSU Rainwater. Harvester Model as assisted by Jeffery Johnson, E.I. of NCSU along
with his email indicating the tanks must be sized for the volume treated because the ratio of small roof
area to actual demand.
Vegetated Setbacks: This project is outside of the 30ft setback but within the 50ft setback, which is allowed
for redevelopment projects. Some areas in the 1994 documentation were labeled as redevelopment, but the
current proposal is not clear. 1 have highlighted key regulations below. Please clarify how the proposed
configuration meets the regulatory requirements
It has been determined that the existing seawater basins within the setbacks is water dependent, therefore
can remain and the rain harvesting tanks placed on them.
If you have any other questions or comments, please give me a call.

Ginger,
OK, that makes more sense. If the main function of the structure is to take in seawater, then I would agree that that
would be water dependent. It sounds like you need to move forward in that direction. I am not sure at this point if you
are also asking about redevelopment for other aspects of the design? I just tried to call you, but you weren't at your
desk. We may be able to better resolve this over the phone if there are questions remaining.
Thanks,
Kelly

Subject: RE: [External] RE: SW8 960424, Carteret County Community College
Ginger,
This is a lot of information, and it touches on a lot of different aspects of the regulations. It is also further complicated
because it is not immediately clear on the 1996 plans or in the permit text how redevelopment has been done on this
site historically. As you know, if it were done today, we would show the various areas of redevelopment on the plans,
quantify the before and after impervious, and we would describe the before and after water treatment. If we were to
modify such a permit today we would update the before/after impervious data and before/after water treatment
description until you reached the point where the site was no longer "redevelopment" as measured against the original
baseline. I do not know what the "baseline" is in this case. Also, the permit talks about four "wet pond/infiltration"
systems, which appear to be "alternative designs" (which further complicates things because there aren't standard
criteria for those). I do not know where the drainage areas are for those four systems, or how redevelopment in the
proposed area(s) would impact the site overall.
I am all for finding the easiest and quickest path forward. But, I honestly don't know what that is. Here are some
thoughts on your email with regulatory citations for each item. If you all can establish that you can do what you want to
do and meet these rules, then that is great. Or, perhaps you aren't triggering into the 2017 rules under some other path
forward, and that would be fine, too. It just may take some research to figure it out.
Redevelopment Exemption (which was a called "Redevelopment Exclusion" in the 2008 Rule) [.1001(1)(f)]: You
can have redevelopment for a portion of the site (assuming no impervious increase and equal/better
stormwater control) if we can establish where the redevelopment boundaries are and that those boundaries
don't overlap other drainage areas. We also have to establish a baseline for redevelopment. Since State
Stormwater permitting started on 1/1/88, any impervious in place prior to that is grandfathered. Impervious
put in place after that date could also be grandfathered if we can establish that it was put in place without
triggering the need to get a State Stormwater permit to put it there. (For instance, it the impervious area were
built incrementally over several years such that permits weren't triggered.)
The task of determining the permitted drainage areas and the potential overlapping would be extremely difficult
and not a route I think should approach at this time.
2. Setbacks/Buffers [.1019(6)(b)]: Redevelopment setbacks are 30ft. 1 talked to other staff about this, and we
think that if there is an existing slab in the 30ft and you are going to just change what is on top of that slab
without increasing its size then that is fine with State Stormwater as long as it is fine with LAMA or any other
agency that may have jurisdiction on that decision.
The concrete slab in question is actually the southern portion of the existing flow -through seawater basin that was
constructed in 2005 for the aquaculture process. This area is not being expanded. It is surrounded by a block wall
(see attached). I was told by CAMA yesterday that they have no problems with the location of the seawater basin in
the 30' buffer and only waiting on comments from the Corps to permit the Major CAMA application. CAMA also
mentioned that it was water dependent and I assume because of pulling water from the sound as part of the

aquaculture process. The southern portion is no longer being utilized as a seawater basin but now proposed as the
pad for the rain tanks.
3. Water Dependent Structure [.1003(4)(d)(ii)]: This regulation essentially says that you can put this type of BUA in
the setback if you can't put it elsewhere, if the BUA is minimized, and if channeling is avoided. Maybe we can
discuss this further. Are you saying that the cistern pad is water -dependent or is there another structure and
I'm misunderstanding this?
Addressed in 2 above
Thanks,
Kelly

Kelly,
I reread the GS highlighted below and the concrete area that the rain tanks are being set on do not meet this criteria.
That being said, I have reviewed a couple of older drawing files and stumbled across a demolition plan from 1995 (pdf
attached). This shows that there was an existing building and other impervious areas within the 30' and 50' buffers. The
approximate existing BUA (1,400 sf), calculated only within the 30' buffer near this building, provides enough impervious
to maintain the entire existing concrete aquaculture feature shown on our current submittal (421 sf). Even though the
aquaculture facility was not submitted as redevelopment for approval back in 1994-95 would DEQ entertain utilizing this
existing impervious to keep this portion of this concrete structure and not propose treatment. (We proposed to utilize
this existing concrete as the pad and anchoring for the rain tank installation.) This is based solely on the fact that no
proposed impervious has been constructed elsewhere on the campus within the 30' buffer. From Google Earth and as
confirmed by the College, it appears this facility was constructed around 2005. Not sure if this makes a difference or not
but the aquaculture facility could also be considered a water dependent use.
If we are allowed to utilize this previously existing impervious within the 30' buffer as a redevelopment piece of the
permit, there is enough area to accommodate the existing concrete sidewalk mentioned in item 1.1b.i and ii., of the
Additional Info letter dated 1.10.18.
I was also able to locate an aerial from the 70's which shows even more buildings within the buffer as this site used to be
the home of a menhaden fish processing plant. However this was prior to any existing conditions survey being done on
the property. Please let me know if you have any questions.

I have emailed Sarah Waickowski with NCSU in regards to the rain harvesting model and she is out until January 24"1
because of surgery. Her out of office reply gave two other individuals which are going to possibly take a look at the
information. I know you are out on vacation this week, but wanted to update you on the status and request for a two
week extension on the RFI. We will touch base next week and hopefully I will have some info in regards to the model.

Ginger,
I was going to call you in a minute, but I wanted to go ahead and send you this because I think this is what you will be
asking me about. I didn't know this when I wrote the letter, but it came up on something since then. Evidently you can
have BUA in the buffer if the project is SA, ORW or HQW if you treat it. (This is odd because other waters that are less
protected are not afforded this option.)

Hi,
Here's a worksheet that will help you with designing your passive drawdown if you choose to implement it. Also, are you
required to treat 3.66" or is that the rainfall depth you want to treat?
Thanks,

Ginger,
Thanks for following up. I've looked at the model and you need to either put in an output for the usage (Figure 1),
which you said is 1800 gal/day, or use the passive release (Figure 2) so the system can make room to capture
subsequent storms.
One issue that I am seeing is that the roof area is too small to capture enough rain to meet a demand of 1800 gal/day.
If you are willing to use the RWH as a source when. it does rain, and use municipal water during the other days, then
you will need to adjust tank sizes (Figure 3) to get your capture volume appropriate for permitting.
Hope this helps,
Jeffrey

Sarah,
I am currently working on a rain harvesting system for the College to use for the existing aquaculture operation and
curious if you would be able to assist with the model. We are also using the system as a means to meet the coastal
stormwater requirements draining to SA waters. I have attempted to input the data into the Rain Harvesting model
but unsure if the model should to be used for this project type. I have attached a couple of screen shots from the
model and attached a pdf of the plans for the project.

Dear Dr. Hauser:
ROY COOPER

TRACY DAVIS
Director
The Wilmington Regional Office received and accepted a State Stormwater Management Permit
Application for the subject project on December 8, 2017. A preliminary in-depth review of that
information has determined that the application is not complete and that additional information is needed.
To continue the review, please provide the following additional information:
1. Clarifications:
a. Drainage Area: Please verify that the proposed system is a stand-alone system which will
not impact any of the currently -permitted drainage areas. (The 1994 approved plans are
not clear where the systems' drainage areas are located.)
b. Sidewalk:
i. Please verify that the sidewalk shown on the plans is not being proposed with this
application. It appears that this application is only for a new rainwater harvesting
system to collect rainwater from a new building.
ii. The 1994 permitted plans do not appear to show the sidewalk on the proposed
plan. There are other areas on the site that also appear to be constructed
differently than the 1994 plan as well. Please clarify how these items will be
addressed.
Project Name: The current permit as well as the current application show that the permit
is to be issued to "Carteret Community College", but the deed shows that "Carteret
Technical College" owns the land. Please clarify why there is a discrepancy.
2. Rainwater Harvesting: Please submit documentation that the proposed system will meet the three
requirements in 15A NCAC 02H .1057, which is attached for your reference. For .1057(4),
please submit a copy of the NCSU Rainwater Harvester Model data showing that the system will
treat at least 85% of the annual runoff.

vegetated setbacks from perennial waterbodies, perennial streams, and intermittent
streams shall be at least 50 feet in width for new development and at least 30 feet in
width for redevelopment and shall comply with Rule .1003(4) of this Section.
b. 15A NCAC 021-I .1002(41) and GS143-214.7: Redevelopment is defined as, "Any land -
disturbing activity that does not result in a net increase in built -upon area and that
provides greater or equal stormwater control to that of the previous development."
c. 15A NCAC 02H .1003(4): Vegetated setbacks shall be required adjacent to waters as
specified in the stormwater rules to which the project is subject pursuant to this Section,
in addition to the following requirements applicable to all vegetated setbacks:
(a) The width of a vegetated setback shall be measured horizontally from the
normal pool elevation of impounded structures, from the top of bank of each side
of streams or rivers, and from the mean high waterline of tidal waters,
perpendicular to the shoreline;
(b) Vegetated setbacks may be cleared or graded, but shall be replanted and
maintained in grass or other vegetation;
(c) Built -upon area that meets the requirements of G.S. 143-214.7(b2)(2) shall be
allowed within the vegetated setback.
(d) Built -upon area that does not meet the requirements of G.S. 143-214.7(b2)(2)
shall be allowed within a vegetated setback when it is not practical to locate the
built -upon area elsewhere, the built -upon area within the vegetated setback is
minimized, and channelizing runoff from the built -upon area is avoided. Built -
upon area within the vegetated setback shall be limited to:
(i) Publicly -funded linear projects such as roads; greenways, and
sidewalks;
(it) Water Dependent Structures; and
(in) Minimal footprint uses such as poles, signs, utility appurtenances,

15A NCAC 02H .1057 MDC FOR RAINWATER HARVESTING
The purpose of this Rule is to set forth the design requirements for rainwater harvesting
systems that are constructed to meet the requirements of this Section.
(1) MAJOR COMPONENTS OF A RAINWATER HARVESTING SYSTEM. Rainwater
harvesting systems shall include the following components:
(a) a collection system;
(b) a pre-treatment device to minimize gross and coarse solids collection
in the tank,
(c) a cistern or other storage device;
(d) an overflow; and
(e) a distribution system.
(2) FATE OF CAPTURED WATER. Captured stonnwater shall be used or
discharged as follows:
(a) use to meet a water demand. The usage, type, volume, frequency, and
seasonality of water demand shall be established and justified;
(b) discharge through a passive drawdown device to a vegetated
infiltration area or another SCM; or
(c) a combination of use and passive discharge.
(3) SIZING. A rainwater harvesting system shall be considered as a primary SCM
if the system is sized and water demand, passive discharge, or a combination
of the two is provided for 85 percent of the total annual runoff volume as
demonstrated through water balance calculations.
(4) WATER BALANCE CALCULATIONS. The water balance shall be calculated
using the NCSU Rainwater Harvester model, which is herein incorporated by
reference, including subsequent amendments and editions, and may be
accessed at no cost at littps://stormwater.b2ie.iicsu.edu/, or another
continuous -simulation hydrologic model that calculates the water balance on
a daily or more frequent time -step using a minimum of five representative
years of actual rainfall records. The model shall account for withdrawals from
the cistern for use, active or passive drawdown, and additions to the cistern
by rainfall, runoff, and a make-up water source if applicable.
(5) DISTRIBUTION SYSTEM. The distribution system shall be tested for
functionality prior to the completion of the rainwater harvesting system. 'rile
design shall include a protocol for testing the functionality of the distribution
system upon completion of the initial system and upon additions to the
existing system.
(6) SIGNAGE REQUIREMENTS. All harvested rainwater outlets such as spigots
and hose bibs, and appurtenances shall be labeled as "Non -Potable Water" to
warn the public and others that the water is not intended for drinking. Passive
drawdown devices, when employed, shall be marked with identifying signage
or labels that are visible to owners and maintenance personnel.

CARTERET COMMUNITY COLLEGE/NC SEA GRANT SHELLFISH
MARICULTURE DEMONSTRATION CENTER
PROJECT NARRATIVE
Primary Applicant: Dr. John Hauser, Carteret Community College
Agent: David Cerino, Carteret Community College
Background: In 2015, Weirich and Cerino, along with Ami Wilbur and Troy Alphin of UNCW
developed a proposal entitled "Expansion and Diversification of the North Carolina Shellfish
Aquaculture Industry" that was submitted to the NOAA Aquaculture Extension and Technology
Program. The proposal was successful and funds were received to initiate work that involves
comparison of oyster gear types and different native oyster strains at industry partner sites,
evaluation of sunray venus clams as a means to diversify the industry, and establishing shellfish
mariculture demonstration centers at UNC W and at a site on Bogue Sound shared by NCSU
CMAST and CCC in Morehead City. CAMA Major and Stormwater Management permits are
being requested for the demonstration site on the Carteret Community College campus.
Purpose: The purpose of the proposed shellfish mariculture demonstration center is to provide a
site for hands on training of entrepreneurs and existing shellfish producers via workshops,
seminars, short courses, and community college curriculum courses. The proposed structure
(aka Pavilion) will provide a safe and comfortable working environment for staff, students, and
researchers.
Site description: The proposed site consists of a 26.9 acre parcel of land containing the Carteret
Community College (CCC) Campus and theNorth Carolina State University Center for Marine
Sciences and Technology (CMAST). The total impervious area on this land will increase to
10.53%.
Rainwater harvest system description: The pavilion and adjacent storage units will create an
impervious surface area of 2,341 ft2. The structures will lave a single continuous metal roof
towards a gutter system pits e comprised of 5" gutters with two downspouts connected to
reservoirs with 4" sch80 PVC, that will divert the rainwater to a set of two 3,000 gallon water
storage reservoirs (6,000 gallon total capacity). The I yr-24hr storm rainfall amount for the
proposed area is 3.66 inches. The minimum required storage capacity for the system is 5,098
gallons.
Water from the storage vessels will be pumped out by one horsepower, 10 stage booster pumps
that backwash the microscreen drum filters for the seawater that is pumped into the CCC Marine
Aquaculture Facility. The water will be used at an average rate of 7GPM. The storage vessels
will be outfitted with emergency overflows which will discharge onto the existing concrete pad.
If sufficient rainwater is not available in the reservoirs, well water will be used to maintain a
minimum water level at the pump intake through the use of an automatic float valve.
Storm and hurricane plan: The site will be managed according to CMAST and CCC storm
and hurricane policy. The reservoirs will be strapped down to prevent hazard or loss.
