RE: Norton Ridge NOV(+/-5.5 Acres)
Corrective Action Plan
Macon County, North Carolina
Dear Mr. Brown and Mr. Moore,
Please reference the letter of Unauthorized Activity (UA) was issued by the United States
Army Corps of Engineers (USACE) (SA W-2019-02248 issued 12/5/2019) and Notice of
Violation (NOV) from the NC Department of Environmental Quality (NCDEQ) (NOV-
2019-CV-0009 issued 11/21/2019) (Attachment A). The UA was issued for unauthorized
work in and around Norton Prong, including impacts to several unnamed tributaries
associated with construction of a pond.
This Corrective Action Plan details wetland and stream restoration planned on site. The
approximately 5.5-acre site is owned by Mr. John W. Meshad and is located at Tract 5 on
Norton Ridge �oad, Highlands, Macon County, North Carolina (35.094552, -83.189099)
· (Figure I).
The applicant hired Headwaters Engineering to design the restoration of the two
unnamed tributaries to Big Norton Prong. The restoration of these steams should
satisfy the concerns of both the USACE UA and the NCDEQ NOV. Details of the
stream restoration can be found in Attachment B: Construction Plans for Restoration
UTs to Big Norton Prong by Headwaters Engineering. Approximately 163 linear
feet of Stream 3 (S3) and 227 linear feet of Stream 4 (S4) will be restored.
Upon completion of the stream restoration, as-built plans will be submitted. The
restored channels of S3 and S4 will be monitored via photographs for 18 months to
ensure stream stability.

Details of the wetland restoration:
1.Approximately 0.151 acres of unauthorized fill material will be removed from
Wetland 4 (W 4) (Figure 2) using a backhoe or similar excavation type equipment.
The identified area of Wetland W 4 will be regraded to the original elevation and
soil profile present prior to the unauthorized activity. Excavation will be complete
once the pre-existing layer of wetland hydric soil is reached.
2.Fill removed from the wetland will be relocated adjacent to the stream restoration
area (old pond area), if needed, or an upland location onsite and appropriately
stabilized (seeded with a straw mulch layer and silt fence perimeter).
3.In order to restore the emergent/scru b-shrub wetland vegetation within W4 the
impacted areas will be seeded with Ernst wetland seed mix (ERNMX-305) and
planted with live stakes that reflect species currently located within surrounding
area wetlands. Appropriate species include black willow (Salix nigra), common
buttonbush (Cephalanthus occidentalis), tag alder (A/nus serrulata), redosier
dogwood (Cornus sericea), and elderberry (Sambucus nigra). Species planted
may vary depending on availability but must be native wetland species.
Approximately 100 total live stakes will be planted on 8-foot centers. See
Attachment B for planting details.
4.Restoration efforts will begin upon USACE approval. It is anticipated that fill
removal and application of the wetland seed mix will be completed within 60
days of approval. Live stakes will be planted during the next dormant season,
typically from December to March.
The applicant will be applying for an Erosion and Sediment Control permit for the pond
construction, in uplands, and the stream restoration activities. The applicant has been in
contact with Stan Aiken to obtain a trout buffer variance for the restored stream channels.
Please do not hesitate to contact me at 828-698-9800 if you have any questions regarding
this Corrective Action Plan.
Sincerely,
Tyson Kurtz

DEPARTMENT OF THE ARMY WILMINGTON DISTRICT, CORPS OF ENGINEERS 151 PATTON AVENUE ROOM208 ASHEVILLE, NORTH CAROLINA 28801-5006 Regulatory Division SAW-2019-02248 Mr. John Meshad 1417 Kimlira Lane Sarasota, Florida 34231 Mr. Larry Rogers December 5, 2019 Larry Rogers Construction Company 776 Dillard Road Highlands, North Carolina 287 41 Dear Sirs: On November 21, 2019, the North Carolina Department of Environmental Quality, Division of Water Resources (DWR), issued a notice of violation (NOV-2019-CV-0009) for clearing and grading activities associated with construction of a pond at Mr. Meshad's property (PIN 7541-75-3732) located off Norton Ridge Road, approximately 0.2 miles north of the. intersection of Norton Ridge Road and Shortoff Road, in Highlands, Macon County, North Carolina. Coordinates are 35.09434, -83.18893. Staff from our Asheville Regulatory Field Office (Corps) contacted Mr. Andrew Moore, DWR, and Mr. Joe Allen, Macon County Planning, Permit, and Development Department, as part of our effort to determine whether or not th~ pond construction involved a violation of the Clean Water Act (CWA) under the Department of Army's (DA) authority. The U.S. Army Corps of Engineers administers Section 404 of the CWA. Under Section 404 of the CWA, a DA permit is required for the discharge of dredged or fill material into waters of the United States (wetlands, streams, lakes, and marine waters). . Based on the information obtained thus far in our investigation, fill has been placed in waters of U.S. (WoUS) as a result of the pond construction without authorization from the DA. The activities were conducted by Larry Rogers Construction Company, as directed by Mr. Meshad. This 5.47-acre residential property includes unnamed tributaries (UTs) of Norton Prong and a portion of Norton Prong which is classified as a perennial stream that flows into Big Creek and ultimately into the Little Tennessee River. Aerial imagery of the site and other Geographic Information System (GIS) data
-2-layers depict an open water impoundment of an UT and possible wetlands on the property. The Corps has initially determined that 200-300 linear feet of streams, open waters, and potentially some wetlands were graded and filled to construct the pond. These activities, undertaken in WoUS without the prior approval from this office in the form of a Department of the Army (DA) permit, constitutes violations of Section 301 of the Clean Water Act (33 USC 1311 ). By copy of this letter, you should cease and desist from any further unauthorized work within WoUS, including wetlands. In order to determine the appropriate course of action in this matter, we request that you provide the following information in writing no later than December 20, 2019: 1. A detailed accounting of all grading, filling, flooding, and/or mechanized land clearing that has occurred in WoUS at the property during the last 24 months. This accounting must disclose in detail the length and/or area of WoUS affected by grading, filling, mechanized land clearing, and/or flooding, the date the work was conducted, the name and current address of the person(s) who conducted the work and the purpose of the work. 2. A statement regarding your intention to resolve this matter either through full restoration of the impacted stream, wetlands, and open waters or after-the-fact permitting, or a combination of permitting and restoration. Do note, activities conducted in areas outside of the DA jurisdiction and the unauthorized activities conducted within WoUS at the property does not imply that the Corps will necessarily approve the impacts to WoUS noted in this document or any future proposal to impact WoUS on this property. Failure to comply with this request may result in referral of this matter to the United States Attorney with a recommendation for appropriate action. If you have any questions regarding this notice, please contact Mr. David Brown by telephone at 828-271-7980, ext. 4232 or by e-mail at david.w.brown@usace.army.mil.

Failure to Secure 401 Water Quality Certification
Stream Standard Violation – Removal of Best Usage
Macon County
Response deadline: December 20, 2019
Dear Mr. Meshad:
On November 19, 2019, Andrew Moore from the Asheville Regional Office of the Division of
Water Resources (DWR) conducted a site inspection of your property on Norton Ridge Road in
Highlands, North Carolina. The site inspection was conducted after receiving notification from
Macon County that grading activities on the property may be impacting streams. Staff with
Macon County Planning, Permitting, and Development were present during the inspection. Your
property caretaker, Phillip Gates, was also present for a portion of the inspection.
During the site inspection, a recently constructed pond was observed to have been excavated
within the footprint of several unnamed tributaries of Norton Prong (WS-II; Trout; HQW). A
recently installed culvert was observed within Norton Prong. A review of DWR files indicates no
approval has been issued for the impacts. As a result of the site inspection and file review, the
following violations were identified:
VIOLATIONS
I. Failure to Secure a 401 Water Quality Certification (WQC) – Title 15A NCAC 02H
.0500 requires water quality certifications pursuant to Section 401 of the Clean Water Act
whenever construction or operation of facilities will result in a discharge into

jurisdictional waters, including wetlands, as described in 33 CFR Part 323. A file review
confirmed that a Pre-Construction Notification has not been received by the DWR for
this project and that a 401 Water Quality Certification has not been issued.
II. Removal of Best Usage – Title 15A NCAC 02B .0211 (2) requires that “The waters shall
be suitable for aquatic propagation and maintenance of biological integrity, wildlife,
secondary recreation, and agriculture; sources of water pollution which preclude any of
these uses on either a short-term or long-term basis shall be considered to be violating a
water quality standard.” The unauthorized impacts to the unnamed tributaries and Norton
Prong represent a removal of use.
REQUIRED RESPONSE
Accordingly, you are directed to respond to this letter in writing by December 20, 2019. Your
response should be sent to this office at the footer address or via email to
Andrew.W.Moore@ncdenr.gov and include the following:
1. Please explain when construction (excavation, grubbing, and clearing) began at the site.
2. Please clearly explain why appropriate 401 WQC and 404 Permit were not secured.
3. Please provide a map that exactly details all waters on the site (including streams and
wetlands) and the areas that were impacted.
4. Please explain how you plan to resolve the 401 Water Quality Certification violation. Two
(2) options exist:
a. Apply to the U.S. Army Corps of Engineers (USACE) for and receive a 404 Permit
pertaining to the existing stream and wetland impacts. A 401 WQC will be required
if the activities are permitted by the USACE. The application process as described
does not guarantee the impacts will be approved.
b. Restore the streams to their pre-existing condition.
If pursuing Option 1:
a. Contact the USACE to determine the permitting needs of the activities you have
undertaken. The Asheville office phone number is (828) 271-7980.
b. Provide a proposed schedule of when you expect to have the required permit
application (401 WQC application) submitted to the DWR.
If pursuing Option 2:

a. Submit a Stream Restoration Plan to this office for review and approval. The plan
must provide details regarding how the stream channels will be restored and how
the buffer along the streambanks will be restored. The Plan must be approved by
DWR before being implemented.
b. The plan must include the measures that will be used for temporary stabilization
and sediment control while this work is under way.
c. Once the restoration is complete, you must notify this office so that a follow-up
inspection may be conducted.
Thank you for your attention to this matter. This office requires that the violations, as detailed
above, be abated immediately and properly resolved. Environmental damage and/or failure to
secure proper authorizations have been documented on the subject tract as stated above. Your
efforts to undertake actions to bring the subject site back into compliance is not an admission,
rather it is an action that must be taken in order to begin to resolve ongoing environmental issues.
Pursuant to G.S. 143-215.6A, these violations and any future violations are subject to a civil
penalty assessment of up to a maximum $25,000.00 per day for each violation. Your above-
mentioned response to this correspondence, the degree and extent of harm to the environment,
and the duration and gravity of the violation(s) will be considered in any civil penalty assessment
process that may occur.
Should you have any questions regarding these matters, please contact Andrew Moore at (828)
296-4684 or Andrew.W.Moore@ncdenr.gov.
