DANIEL SMITH Director August 4, 2020 NORTH CAROL.INA Environmental duality CERTIFIED MAIL 70191640 00001354 4351 RETURN RECEIPT REQUESTED Tryon Equestrian Partners, LLC Attn: Mr. Jeff Brown 4066 Pea Ridge Road Mill Spring, NC 28756 Subject: NOTICE OF VIOLATION and RECOMMENDATION FOR ENFORCEMENT Tryon International Equestrian Center NOV-2020-SS-0014 Stream Standard Violation —Other Waste (In -stream sediment) Stream Standard Violation —Removal of Best Usage Stream Standard Violation —Turbidity 401 Water Quality Certification (WQC) Conditions Polk County Required Response Date: September 4, 2020 Dear Mr. Brown: On July 29, 2020, Andrew Moore from the Asheville Regional Office of the Division of Water Resources (DWR) conducted a site inspection of the Tryon International Equestrian Center (TIEC) in Polk County. The site inspection was initiated in response to photographs and video provided to this office reportedly depicting a turbid stream draining from TIEC and its confluence with White Oak Creek. Wayne Watkins with Odom Engineering was present during the inspection. During the site inspection, the unnamed tributary (UT) of White Oak Creek running between the office and the covered arena (Labelled as Stream KB on previous correspondence) was turbid. Site contractors were observed to be flushing sediment, which had accumulated on the road in front of the office from erosion associated with backfilling a retaining wall, into the stormwater drainage system. The stormwater system discharges to Stream KB. Water samples were collected from stream KB above and below the stormwater discharge. The stream below the covered arena project near the 60-inch bypass outfall (Stream KA) was also evaluated. The outfall and boulder toe were observed to have failed releasing sediment and gravel into stream KA. Please note that this is an area that DWR expressed concern about in a Request for Additional Information dated August 27, 2018. The response to the request included a D E Q�� North Carolina Department of Environmental Quality � Division of Water Resources Asheville Regional Office 2090 U.S. Highway 70 � Swannanoa, North Carolina 28778 vOry rN Cx:40:.itiA � o.naro�em or E�.w�����a�:r� /`� 828.296.4500 DocuSign Envelope ID: B58C5A1A-2FFD-4881-96C9-BC01E717D953 Tryon Equestrian Partners, LLC August 4, 2020 Page 2 of 4 streambank stabilization plan consisting of a rock toe and athree-year monitoring plan. DWR received the as -built report as part of the monitoring plan on May 29, 2020. As a result of the site inspection, file review, and laboratory analysis of water samples, the following violations were identified: VIOLATIONS L Other Waste (In -Stream Sediment) — 15A NCAC 02B .0211 (12) —Title 15A NCAC 02B .0211 (12) requires that "Oils, deleterious substances, colored, or other wastes: only such amounts as shall not render the waters injurious to public health, secondary recreation, or to aquatic life and wildlife, or adversely affect the palatability of fish, aesthetic quality, or impair the waters for any designated uses." Approximately 50 feet of an unnamed tributary of White Oak Creek (Class C) was impacted by sediment and gravel deposition from the 60-inch bypass outfall failure. II. Removal of Best Usage — 15A NCAC 02B .0211 (2) —Title 15A NCAC 02B .0211 (2) requires that "The waters shall be suitable for aquatic life propagation and maintenance of biological integrity, wildlife, secondary recreation, and agriculture. Sources of water pollution that preclude any of these uses on either ashort-term or long-term basis shall be considered to be violating a water quality standard." The sediment and gravel deposition within the stream channel results in a removal of use. III. Turbidity — 15A NCAC 02B .0211 (21) —Title 15A NCAC 02B .0211 (21) requires that "Turbidity: the turbidity in the receiving water shall not exceed 50 Nephelometric Turbidity Units (NTU) in streams not designated as trout waters and 10 NTU in streams, lakes, or reservoirs designated as trout waters; for lakes and reservoirs not designated as trout waters, the turbidity shall not exceed 25 NTU; if turbidity exceeds these levels due to natural background conditions, the existing turbidity level shall not be increased." The water sample collected from KB (Class C) upstream of the stormwater discharge was 45 NTUs. The water sample collected from KB downstream of the stormwater discharge was 190 NTUs. IV. Individua1401 WQC Condition Violations —Tryon Equestrian Partners, LLC submitted a North Carolina Individua1401 WQC modification request dated Apri127, 2018. DWR issued an approval letter for the modifications on November 16, 2018. The WQC issued for the project impacts specifies the activities must follow all conditions listed therein. The following condition violations were noted: Conditions # 5—No waste spoil, solids, or fill waters, or riparian areas beyond the footprint of the impacts depicted in the application for this project. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices shall be performed so that no violations of state water quality standards, statutes, or rules occur.

Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation, and operation and maintenance of such Best Management Practices. Condition #8 —Construction Stormwater Permit NCGO 10000. An NPDES Construction Stormwater Permit is required for construction projects that disturb one (1) or more acres of land. This Permit allows stormwater to be discharged during land disturbing activities as stipulated in the conditions of the permit. If your project is covered by the permit, full compliance with permit conditions including the erosion and sedimentation control plan, inspections and maintenance, self - monitoring, record keeping and reporting requirements is required. REQUIRED RESPONSE Accordingly, you are directed to respond to this letter by September 4, 2020. Your response should be sent to the attention of Andrew Moore at the footer address or Andrew.W.Moore(a�ncdenr.gov and should include the following: Stream Standard —Other Waste (In -Stream Sediment) a. Please provide a Sediment Removal and Stabilization Plan for review and approval. The plan must address the removal of accumulated sediment and gravel below the 60-inch bypass outfall structure. The sediment removal plan should include: • A narrative explaining how sediment and gravel will be removed including techniques, manpower and tools to be used. • A proposed schedule with dates that indicate when you expect to begin and complete the removal of sediment and gravel. • A narrative explaining how and where the removed sediment and gravel will be disposed and stabilized. • Please explain how turbidity standards will not be exceeded during sediment removal activities. The Stabilization Plan should include: • A narrative and construction details explaining how the outfall will be re- constructed to withstand expected storm events and prevent additional sedimentation to the stream. b. Following sediment removal and stabilization, the cross sections described in the October 16, 2018 Request for Additional Information response shall be re -surveyed and overlayed on the as -built data. The cross -sections shall be provided to DWR.
