INTRODUCTION The Black Beaver Road Project is an approximately 19.3-acre tract of land (parcel IDs 8593-64-2665-000 and 8593-74-0366--000) on Black Beaver Road and Steel Creek Road in Brevard, Transylvania County, North Carolina (the "Property"). The Property is owned by William Scherer. Mr. Scherer initiated the project for the harvesting of timber on the tracts. He contracted with Jeremy Whitesides d/b/a Richland Creek Timber. Timber removal and land clearing began in the fall of 2016. Prior to the removal of any timber, Mr. Scherer and Richland Creek Timber (Mr. Whitesides) consulted with the North Carolina Forest Service regarding Best Management Practices for the logging operation including the placement of culverts in Steel Creek. The logging operation utilized BMP's recommended by the NC Forest Service. After the logs were cut and stumps removed, grass was planted. Mr. Scherer raises horses on his Steel Creek property. He intends to replant some trees in steeper areas and utilize the remaining cleared area as pastures. Heavy rains in the late winter and early spring of 2017 caused significant erosion on the Property. Following inspections of the site on February 28 and March 2, 2017, the North Carolina Division of Water Resources (DWR) issued a Notice of Violation and Recommendation for Enforcement on March 7, 2017. The US Army Corps of Engineers (USACE) issued a Notice of Unauthorized Activity on March 6, 2017. Candace Mance of Conrad and Scherer responded to the NOVs on March 24, 2017. On March 29, 2017, Mr. Scherer, representatives from McGill Associates and counsel for Mr. Scherer, met with representatives of DWR and USACE on the Property. Impacts were inspected, the placement of temporary in -stream measures to control sediment were discussed as well as the removal of sediment from the streams and delineation of wetlands. There were several significant rain events in the days after the March 29 meeting. Mr. Scherer and the Richland Creek contractors augmented by a crew employed by Mr. Scherer worked diligently to install and maintain temporary measures and to clean out some existing measures designed to retain sediment. Those measures have been and are being maintained. Grass is growing on the site. This Corrective Action Plan is in response to items discussed during the March 291h meeting. Mr. Scherer and his attorney, in conjunction with McGill Associates, P.A., have developed a Corrective Action Plan (CAP) which includes a Site Stabilization Plan, Sediment Removal Plan, and a Regulatory Compliance Plan. R&S 1812446 1 Page 4 of 12 SECTION 2. SITE STABILIZATION PLAN Efforts to stabilize the site have been on -going since the first large storm event resulted in significant sediment impacts to Steel Creek and associated tributaries. These efforts include construction of sediment traps, installation of silt fence, seeding and placement of erosion control mats. To date, portions of the site have developed healthy stands of grass and other areas show signs that grass is growing rapidly, but stabilization efforts are ongoing. Multiple heavy storm events in late March and early April caused some constructed measures to fail, but the Owner has maintained a contractor on -site to make repairs and to implement improvements and new measures recommended by McGill Associates. McGill has been onsite multiple times to answer erosion control questions and describe required erosion control changes. McGill Associates has conducted a topographic survey of the site and developed a Site Stabilization Plan to address all disturbed areas on the site. A copy of this Plan is included as an attachment to this CAP. The plan includes multiple sediment basins with riser outlets, skimmer drains, riprap dissipaters, and emergency overflow weirs. Drainage from disturbed areas is routed to basins by a network of diversion ditches, some stabilized with riprap due to high shear stresses expected. Where sediment basins need to be supplemented with additional measures, sediment traps and silt fence have been specified. Silt fence has also been specified along the stream buffer to trap any remaining sediments, and for a visual reminder as to the stream buffer location. In addition, specifications for seeding and permanent stabilization are included in the plan (Attached). While topographic survey was obtained, geotechnical borings were not completed, therefore field conditions may alter the final placement of site stabilization (i.e. presence of bedrock may shift sediment basin locations), but sizing calculations and details will remain intact as the stabilization plan is executed. McGill Associates will continue to be available to answer contractor questions and provide periodic oversight during construction of the plan. SECTION 3. SEDIMENT REMOVAL PLAN This section will address the requirement to evaluate the amount of sediment deposited in the stream and describe a plan to remove sediment impacts onsite and downstream of the site. SECTION 3.1 EVAL UATION OF IMPACTS McGill Associates biologists visited the site on April 4 and April 7, 2017 to assess the sediment impacts to streams and wetlands both on and off the site. The attached Sediment Impacts Map (Figures l A and 1 B) shows the extent of streams and wetlands R&S 1812446_1 Page 5 of 12 with sediment impacts between the upper end of the Black Beaver Road site and the Sequoyah Woods lake. Total length of stream channel involved is approximately 2,000 linear feet. The average slope of the affected streams is greater than 5% and typical channel morphology can be described as step -pool with sections of riffle -pool and occasional steep bedrock controlled sections. Sediment deposition throughout the evaluated reach was concentrated in pools with riffle deposits limited to eddies, inner -berm features and low banks. There are numerous channel fragments, braids, and small riparian wetlands that are impacted by sediment as well. The measurement of sediment impacts was focused on pools. The location of each pool is shown on Figures ] A and 1 B. Multiple sediment depth measurements were taken at each pool. Table 1 provides pool length with maximum and average sediment depths for each. Table 2 summarizes the area of channel braids and wetlands impacted by sediment deposition. Photos were taken of the assessment areas during data collection. ION 3.2 SEDIMENT REMOVAL STREAMS AND WETLANDS Sediment removal from Steel Creek and UT -Steel Creek will be accomplished using manual labor "bucket crews". We feel that this technique will be the most cost effective, have the least impact on the streams, and will require the least amount of time to mobilize the effort. Sediment deposits in wetlands and abandoned channel fragments will be removed using the same methods as indicated for the streams. MANPOWER & TOOLS Labor "Bucket" Crew - 6-12 Laborers with shovels and buckets - 2 Supervisors (McGill Assoc., Owner Representative) - 1 Skid -Steer Loader or Tractor w/ Front End Loader (1 operator) - 1 Dump Truck (1 operator) - ATV with dump bed to transport off -site sediment back to site - Water pump of sufficient size to divert flow around work area We estimate that 5 work days will be required to complete the stream sediment removal operation and 2 additional days to remove sediment from wetland areas not immediately adjacent to the streams. The sediment removal operation will be observed and documented by a McGill Associates representative to make sure that the sediment removal is done in accordance with the plan, and to collect the information needed for the final report. The sediment removal operation will move from upstream to downstream. R&S 1812446 1 Page 6 of 12 Sediment removal activities will be conducted in the dry, to the maximum extent practicable, through the use of a pump around operation to limit flow volume during work. This will mitigate further downstream migration of sediment, enhance visibility of the stream bed, and increase the amount of sediment that can effectively be removed. An effort will be made to move any stranded fish upstream of the work area. Typical hand tools are proposed for the bucket crews in the form of shovels and five gallon buckets for sediment removal. Sediment will then be deposited in a front-end loader bucket or ATV dump bed for transport to a disposal area. McGill Associates personnel supervising sediment removal activities will determine when each segment is sufficiently cleaned and the pump around operation can be moved downstream. While sediment deposits have been observed along the entire length of the affected stream channel, the majority of in -channel sediment is located in pools and the primary focus will be on these areas. Riffle sections tend to have less sediment along and adjacent to the thalweg, but may have deposits in eddies and along banks that will be removed when quantities are substantial. McGill Associates personnel will direct sediment removal activities to remove excess sediment while minimizing excessive disturbance to stream banks and high quality habitat. Care will be exercised to maintain natural channel bed substrate, woody debris and other important elements of the stream ecosystem. Any areas along the riparian corridor that are disturbed during the sediment removal operation will be seeded with an appropriate native seed mix and mulched with straw to minimize further erosion potential. DISPOSAL AND STABILIZATION Removed sediment will be disposed of within previously disturbed areas on the project site and in areas protected by erosion control measures shown on the Site Stabilization Plan. Once removal operations are complete and the sediment dries out, this material will be smoothed and permanently stabilized in place. Sediment extracted from Steel Creek inside the Sequoyah Woods development will be loaded into a loader bucket or ATV dump bed and hauled back to Mr. Scherer's property for disposal. To facilitate this operation, a temporary crossing over UT -Steel Creek will be installed at the existing trail crossing location, approximately 120 feet upstream of the confluence with Steel Creek. The temporary crossing will be constructed using timber mats that span the channel and will minimize the direct disturbance of the channel. Upon completion of instream sediment removal activities, the timber mats will be removed and the stream banks will be restored to preexisting elevations and stabilized with erosion control matting as needed and seeded with native seed mix. R&S 1812446 _ 1 Page 7 of 12 SECTION 3.3 SEDIMENT REMOVAL LAKE The approximate 10-acre impoundment in Sequoya Woods traps sediment flowing into the lake from Steel Creek and its tributaries. There is a visible buildup of sediment in upper end of the lake. The area includes the former Steel Creek stream channel and wetland type areas that have developed over the years. Access to this area is limited to a narrow steep gravel drive from Sequoyah Woods Drive to a picnic shelter at the base of the waterfall. It would be very difficult to mobilize a cleanup operation at this location without causing substantial disturbance to the Sequoyah Woods property and potentially impacting wetlands. SECTION 3.4 SCHEDULE/TIMELINE Instream sediment removal is scheduled to begin within roughly two weeks as soon as all site stabilization measures are in place and functioning. Instream sediment removal should be completed in roughly 2 weeks after mobilization of crews and equipment. SECTION 4. REGULATORY COMPLIANCE PLAN During the March 29, 2017 site meeting, the Property Owner was asked to assess and document impacts to streams and wetlands on the Property. McGill Associates assessed and documented impacts on April 4, 2017. The attached 404 Impacts Map (Figure 2) shows the impact locations and includes a table with stream lengths and wetland areas for each location. Total impacts at the Black Beaver Road site are 120 linear feet of stream impact from recently installed culverts and approximately 0.06 acres of wetland fill impacts associated with two linear seep wetlands and one riparian wetland. A complete JD package for all wetlands on the Black Beaver site will be completed and submitted to the Agencies by April 26, 2017. The Owner anticipates pursuing an after -the -fact permit for impacts on the Property. SECTION 5 FINAL REPORT Upon completion of all elements of the Corrective Action Plan, a Final Report will be completed by McGill Associates. The Final Report will contain a description of the completed work, the results of the sediment removal activities, site stabilization measures, and photo documentation. The Final Report will be distributed to NC DWR and the USACE in order to obtain final release of the issued NOV's. R&S 1812446_1 Page 8 of 12 Table 1.
