Permittee: HNH Futures, LLC / Attn: Chad Hollister
Address: 307 Scene -A -Rama Drive
Blowing Rock, NC 28607
Telephone Number: 252-414-0875
Location description: The site is located on Whispering Pines Road, in Boone, Watauga County, NC. Coordinates: 36.22720 -
81.608398.
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 0.328 acres and replaces the previous authorization
dated December 21, 2018 in which impacts have been reduced.
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.

CONSTRUCTION SPECIFICATIONS:
1. GRADE THE BASIN SO THAT THE BOTTOM IS LEVEL FRONT TO BACK AND SIDE TO SIDE.
2. INSTALL POSTS OR SAW HORSES ACROSS THE WIDTH OF THE SEDIMENT TRAP.
3. STEEL POSTS SHOULD BE DRIVEN TO A DEPTH OF 24 INCHES, SPACED A MAXIMUM OF 4
FEET APART, AND INSTALLED UP THE SIDES OF THE BASIN AS WELL. THE TOP OF THE
FABRIC SHOULD BE 6 INCHES HIGHER THAN THE INVERT OF THE SPILLWAY. TOPS OF
BAFFLES SHOULD BE 2 INCHES LOWER THAN THE TOP OF THE BERMS.
4. INSTALL AT LEAST THREE ROWS OF BAFFLES BETWEEN THE INLET AND THE OUTLET
DISCHARGE POINT. BASINS LESS THAN 20 FEET IN LENGTH MAY USE 2 BAFFLES.
h
5. WHEN USING POSTS, ADD A 9 GAUGE SUPPORT WIRE ACROSS THE TOP OF THE MEASURE '
TO PREVENT SAGGING.
6. WRAP POROUS MATERIAL, LIKE JUTE BACKED BY COIR MATERIAL, OVER A SAWHORSE OR

SHOULD HAVE FIVE TO TEN PERCENT OPENINGS IN THE WEAVE. ATTACH FABRIC TO A
SUPPORT WIRE AND A SUPPORT STRUCTURE WITH ZIP TIES, WIRES, OR STAPLES.
7. THE BOTTOM AND SIDES OF THE FABRIC SHOULD BE ANCHORED IN A TRENCH OR PINNED
WITH 12-INCH EROSION CONTROL MATTING STAPLES AT 12" SPACING.
8. DO NOT SPLICE THE FABRIC, BUT USE A CONTINUOUS PIECE ACROSS THE BASIN.
MAINTENANCE:
INSPECT BAFFLES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED
REPAIRS IMMEDIATELY.
BE SURE TO MAINTAIN ACCESS TO THE BAFFLES. SHOULD THE FABRIC OF A BAFFLE COLLAPSE,
TEAR, DECOMPOSE, OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY.
REMOVE SEDIMENT DEPOSITS WHEN IT REACHES HALF FULL TO PROVIDE ADEQUATE STORAGE VOLUME
FOR THE NEXT RAIN AND TO REDUCE PRESSURE ON THE BAFFLES. TAKE CARE TO AVOID DAMAGING
THE BAFFLES DURING CLEANOUT. SEDIMENT DEPTH SHOULD NEVER EXCEED HALF THE DESIGNED
STORAGE DEPTH.
AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED, REMOVE ALL BAFFLE
MATERIALS AND UNSTABLE SEDIMENT DEPOSITS, BRING THE AREA TO GRADE, AND STABILIZE IT.

MAINTENANCE:
INSPECT RIP -RAP PIPE INLET PROTECTION AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (Y2 INCH OR
GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT AND RESTORE THE SEDIMENT STORAGE
AREA TO ITS ORIGINAL DIMENSIONS WHEN THE SEDIMENT HAS ACCUMULATED TO ONE-HALF THE DESIGN DEPTH
OF THE TRAP. PLACE THE SEDIMENT THAT IS REMOVED IN THE DESIGNATED DISPOSAL AREA AND REPLACE THE
CONTAMINATED PART OF THE GRAVEL FACING.
CHECK THE STRUCTURE FOR DAMAGE. ANY RIPRAP DISPLACED FROM STONE HORSESHOE MUST BE REPLACED
IMMEDIATELY.
AFTER ALL THE SEDIMENT -PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE THE STRUCTURE
AND ALL THE UNSTABLE SEDIMENT. SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND PROVIDE

3. CONSTRUCT THE FILTER FABRIC FROM A CONTINUOS ROLL CUT TO LENGTH OF
THE BARRIER TO AVOID JOINTS. WHEN JOINTS ARE NECESSARY, SECURELY
FASTEN THE FILTER CLOTH ONLY AT A SUPPORT POST WITH 4 FEET MINIMUM
OVERLAP TO THE NEXT POST.
4. SUPPORT STANDARD STRENGTH FILTER FABRIC BY WIRE MESH FASTENED
SECURELY TO THE UPSLOPE SIDE OF THE POSTS. EXTEND THE WIRE MESH
FASTENED SECURELY TO THE UPSLOPE SIDE OF THE POSTS. EXTEND THE WIRE
MESH SUPPORT TO THE BOTTOM OF THE TRENCH. FASTEN THE WIRE
REINFORCEMENT, THEN FABRIC ON THE UPSLOPE SIDE OF THE FENCE POST.
WIRE OR PLASTIC ZIP TIES SHOULD HAVE MINIMUM 50 POUND TENSILE STRENGTH.
5. WHEN A WIRE MESH SUPPORT FENCE IS USED, SPACE POSTS A MAXIMUM OF 8
FEET APART. SUPPORT POSTS SHOULD BE DRIVEN SECURELY INTO THE GROUND
A MINIMUM OF 24 INCHES.
6. EXTRA STRENGTH FILTER FABRIC WITH 6 FEET POST SPACING DOES NOT REQUIRE
WIRE MESH SUPPORT FENCE. SECURELY FASTEN THE FILTER FABRIC DIRECTLY TO
POSTS. WIRE OR PLASTIC ZIP TIES SHOULD HAVE MINIMUM 50 POUND TENSILE
STRENGTH.
7. EXCAVATE A TRENCH APPROXIMATELY 4 INCHES WIDE AND 8 INCHES DEEP ALONG
THE PROPOSED LINE OF POSTS AND UPSLOPE FROM THE BARRIER.
8. PLACE 12 INCHES OF THE FABRIC ALONG THE BOTTOM AND SIDE OF THE
TRENCH.
9. BACKFILL THE TRENCH WITH SOIL PLACED OVER THE FILTER FABRIC AND
COMPACT. THOROUGH COMPACTION OF THE BACKFILL IS CRITICAL TO SILT FENCE
PERFORMANCE.
10. DO NOT ATTACH FILTER FABRIC TO EXISTING TREES.
MAINTENANCE:
INSPECT SEDIMENT FENCES ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY
REQUIRED REPAIRS IMMEDIATELY.
SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, TEAR, DECOMPOSE OR BECOME
INEFFECTIVE, REPLACE IT PROMPTLY.
REMOVE SEDIMENT DEPOSITS AS NECESSARY TO PROVIDE ADEQUATE STORAGE VOLUME
FOR THE NEXT RAIN AND REDUCE PRESSURE ON THE FENCE. TAKE CARE TO AVOID
UNDERMINING THE FENCE DURING CLEANOUT.
REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT DEPOSITS AND BRING THE
AREA TO GRADE AND STABILIZE IT AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN
PROPERLY STABILIZED.

MAINTENANCE:
MAINTAIN THE GRAVEL PAD IN A CONDITION TO PREVENT MUD OR SEDIMENT FROM
LEAVING THE CONSTRUCTION SITE. THIS MAY REQUIRE PERIODIC TOP DRESSING WITH
2" STONE. AFTER EACH RAINFALL, INSPECT ANY STRUCTURE USED TO TRAP
SEDIMENT AND CLEAN IT OUT AS NECESSARY. IMMEDIATELY REMOVE ALL
OBJECTIONABLE MATERIALS SPILLED, WASHED, OR TRACKED ONTO PUBLIC ROADWAYS.
