Page 10 of 10 Supplemental Information Section B. Project Information and Prior Project History Question 3e: Typical construction equipment will be used (i.e. backhoe, bulldozer). A two-story climate controlled commercial storage building (34,400 sq ft) and associated parking with 8 spaces for large trucks, cars, and handicap access will be constructed on -site. Question 5b: The applicant originally applied for a Nationwide Permit 39 on September 27, 2018. The application was approved by the US Army Corps of Engineers on December 21, 2018, and by the NC Department of Water Resources on April 5, 2019. A permit modification was submitted for this project on May 28, 2019. The permit modification was subsequently withdrawn on August 22, 2019. Section D. Impact Justification and Mitigation Question la: Minimization The applicant has also worked to design the site to minimize the impact on the wetlands. The original plan was to have the building on the front end (closest to Old 421) of the property, but in order to minimize impact, it was decided to move the building as far back on the site as possible. The number of large parking spaces has been reduced, as well as the size of the building to help with minimizing the impact on the wetlands. Please reference Alternative Site Plan Option 1 and Option 2. The wetland impact is the minimum necessary to develop the site. The proposed plan minimizes on -site wetland impact to 0.328 AC permanent impact out of the total 0.632 AC of wetland on the property. Alternative sites were considered but were deemed not feasible due to higher costs and the topography of the land.

Quad: Deep Gap GENERAL PERMIT (REGIONAL AND NATIONWIDE) VERIFICATION Permittee: HNH Futures, LLC / Attn: Chad Hollister Address:307 Scene-A-Rama Drive Blowing Rock, NC 28607 Telephone Number:252-414-0875 Size (acres): 2.2 acre Nearest Town: Boone Nearest Waterway:Brown Branch Coordinates: 36.227200 -81.608398 River Basin/HUC:New River / 005050001 Location description: The site is located on Whispering Pines Road, in Boone, Watauga County, NC. Description of projects area and activity: This permit authorizes placement of fill for the construction of a storage unit commercial business. Impacts to wetlands authorized by this permit total 0.4 acres. Special Conditions: 1.In order to compensate for impacts associated with this permit, mitigation shall be provided in accordance with the provisions outlined on the most recent version of the attached Compensatory Mitigation Responsibility Transfer Form. The requirements of this form, including any special conditions listed on this form, are hereby incorporated as special conditions of this permit authorization. 2.If additional impacts to waters of the U.S., either on this property or on/adjacent to this property in association with this development/project are proposed at a later date then those impacts will be combined with the current impacts to waters of the U.S. and will be reviewed cumulatively. Generally, compensatory mitigation will be required if individual or cumulative (i.e. past and present) losses or degradation of waters of the U.S. are greater than 150 linear feet of stream channel and/or 0.10 acre of wetland. Additionally, cumulative impacts that result in the loss or degradation of greater than 300 linear feet of stream channel* and/or 0.5 acre of wetland will be processed under an Individual Permit. This verification of the use of the Nationwide Permit Program for this project does not imply that this office will necessarily approve any future proposal to impact waters of the U.S. on this property and/or properties associated with the project. *The District Commander has the ability to waive the 300 linear foot limit for intermittent stream channels on a case-by-case basis. All requests for a waiver must be in writing and shall include rationale for the request. 3. Adjacent/undisturbed wetland areas to the proposed impact areas should be clearly demarcated with protective fencing prior to and during construction activities and remain in-place until permitted activities has been completed and a compliance inspection has been conducted by the Corps project manager. 4. A pre-construction meeting should be coordinated with the Corps project manager to inspect protective wetland fencing prior to any permitted impacts occurring. Applicable Law: Section 404 (Clean Water Act, 33 USC 1344) Section 10 (Rivers and Harbors Act, 33 USC 403) Authorization: Regional General Permit Number or Nationwide Permit Number: 39 SEE ATTACHED RGP or NWP GENERAL, REGIONAL AND SPECIAL CONDITIONS Your work is authorized by the above referenced permit provided it is accomplished in strict accordance with the attached conditions, above noted special conditions, and your submitted application and attached information dated September 27, 2018. Any violation of the attached conditions or deviation from your submitted plans may subject the permittee to a stop work order, a restoration order, a Class I administrative penalty, and/or appropriate legal action. This verification will remain valid until the expiration date identified below unless the nationwide/regional authorization is modified, suspended or revoked. If, prior to the expiration date identified below, the nationwide/regional permit authorization is reissued and/or modified, this verification will remain valid until the expiration date identified below, provided it complies with all requirements of the modified nationwide/regional permit. If the nationwide/regional permit authorization expires or is suspended, revoked, or is modified, such that the activity would no longer comply with the terms and conditions of the nationwide/regional permit, activities which have commenced (i.e., are under construction) or are under contract to commence in reliance upon the nationwide/regionalpermit, will remain authorized provided the activity is completed within twelve months of the date of the nationwide/regional permit’s expiration, modification or revocation, unless discretionary authority has been exercised on a case-by-case basis to modify, suspend or revoke the authorization. Activities subject to Section 404 (as indicated above) may also require an individual Section 401 Water Quality Certification. You should contact the NC Division of Water Resources (telephone 828-296-4500) to determine Section 401 requirements. This Department of the Army verification does not relieve the permittee of the responsibility to obtain any other required Federal, State or local approvals/permits.
