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).

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.

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.

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 From: Ginger Turner[mailto:gturner@stroudengineer.com] Sent: Thursday, February 1, 2018 8:39 AM To: Johnson, Kelly <kelly.p.iohnson@ncdenr.gov> Cc: cerinod (cerinod @carteret.edu) <cerinod@carteret.edu>; Stephen Sparks <sparkss@carteret.edu> Subject: RE: [External] RE: SW8 960424, Carteret County Community College CAUTION: External email. Do not click links or open attachments unless verified'. Send all suspicious email as an attachment to 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.

Also, are you required to treat 3.66" or is that the rainfall depth you want to treat? Thanks, Sarah Waickowski On Mon, Jan 29, 2018 at 11:09 AM, Jeffrey Johnson <jpiohnso(c@ncsu.edu> wrote: 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.

REGAN Secretary 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.

(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.

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. Carteret Community -.College.
