Bailey, PWS Regulatory Project Manager US Army Corps of Engineers CE -SAW -RG -R 3331 Heritage Trade Drive, Suite 105 Wake Forest, North Carolina 27587 RE: Request for Additional Information: City of Eden Waterline to SoVA Megasite, Rockingham Co., SAW -2018-02188 Dear Mr. Bailey: On February 20, 2019, Dewberry Engineers Inc. (Dewberry) received a request for additional information related to the Eden Waterline to SoVA Megasite project. On behalf of the City of Eden, Dewberry's submits the following response. In regards to your response about the rip -rap placement detail on Sheet C22 statement "ROCK DUMPED IN PLACE." The correction has been made to reflect the stream bed line extending across the top of the rip -rap and added the statement, "Rock to be keyed or pushed into bank." Attached are the most recent design plans. Further, in regards to your response about the insufficient information to justify directional drill or jack and bore methods are not practicable for the six (6) proposed stream crossings, Dewberry has revised its plans to jack and bore all tributary stream crossings, and directional drilling Cascade Creek, with the exception of impact site #6. Any unavoidable temporary impact to this stream crossing is necessary as the North Carolina Department of Transportation (NCDOT) will not allow a bore pit with the close proximity to US 311/NC770. The email from Jason Julian of North Carolina Department of Transportation is attached. The open cut request is located at stream SC associated with impact site #6. It is in Dewberry's professional opinion that stream SC does not present suitable habitat for the James spineymussel or the Roanoke logperch. The stream appears to be intermittent with little to no flow. Attached are photographs of the stream in question. Mr. David E. Bailey, PWS US Army Corps of Engineers April 12, 2019 Page 2 of 3 On March 5, 2019, Dewberry received an email from Sue Homewood with North Carolina Division of Water Resources (NCDWR). The NCDWR comments are provided below in italics, followed by Dewberry's response. The stream impact lengths shown in the most recent table appear to be sufficientfor the trench activities but do not seem to include temporary impacts for dewatering activities that are required. Would you please review whether all construction activities can take place within the permanent impacts shown on the table or provide an updated table that includes temporary dewatering impacts. The impact tables have been revised to reflect the updated plans. The City of Eden proposes to jack and bore all tributary stream crossings and directional drill Cascade Creek, with the exception of stream SC. Temporary dewatering impacts will occur in stream SC. With the revised plan, the stream impacts would be temporary and the attached impact table will reflect that change. Condition I.2. of GC4133 (attached) states that utility corridors must be Io' from the top of bank when it runs parallel to a stream. It appears that Impact Site *7 (Stream C is now associated with Impact Site 6) will not meet this condition. Please provide a justification statementfor why the installation cannot be shifted to avoid this impact. If the Division agrees with the justification we will require that Stream SC be dewatered during construction activities within lofeet of the streambank. Please call this out on the plans and identify the length of temporary dewatering impact on the impact table. In regards to impact site 6 on sheet C14, we request a variance to open cut this stream- we are able to fit and bore pit in for proper execution at the rest of the stream crossings. There are some concerns at this location for the following reasons: • There is a high concentration of existing utilities at this locations (2 additional waterlines, telephone, sewer) and there is only room for the bore pit on the east side. • At this location, the bore pit will need to be 20' deep and directly against the road. There is a risk pf undermining the road to perform this work, which would require significant repair and shut down of NC 770. • Directional drill is not an option due to the many utilities located in the vicinity. • The City of Eden would like to keep the utilities within the existing easement. Temporary dewatering has been referenced on the updated plans on sheet C22 and the impact table has been revised to reflect these changes. On March 5, 2019, Dewberry personnel conducted a survey for the federally endangered smooth coneflower in the proposed project area. Based on the results of the survey, Dewberry made the determination that the biological conclusion for the project "May effect, not likely to adversely affect" the smooth coneflower. Attached is the letter sent to U.S Fish and Wildlife Service (USFWS). " Dewberry® Mr. David E.

Based on the recommendation in the referenced letter, Dewberry Engineers Inc. (Dewberry) contacted the Service to discuss the options regarding surveys for the smooth coneflower outside the optimal survey window. The Service recommended visiting a known smooth coneflower location population. Two sites were visited, (The North Carolina Botanical Gardens and a roadside population) and multiple plants were located with stems and flower heads present, with and without seeds. Surveys were conducted by Biologists from Dewberry, Anne Burroughs and Brett Feulner, on March 5, 2019 in the proposed project area. Surveys were conducted throughout the entire project area and no specimens of the smooth coneflower, or any plants resembling the smooth coneflower were observed within the project area. Based on the results of the surveys, Dewberry makes the determination that the biological conclusion for the project is "May effect, not likely to adversely affect" the smooth coneflower and seeks the concurrence from the Service.

OF E X C0 0 1 Page 6h-52 April 2015 Typical Traffic Control Non -Stationary Operation on a Two -Lane Roadway Using Flaggers (Figure TTC-24.1) NOTES: Guidance: 1. Sign spacing distance should be 350'-500' where the posted speed limit is 45 mph or less, and 500'-800' where the posted speed limit is greater than 45 mph. 2. Care should be exercised when establishing the limits of the work zone to insure maximum possible sight distance in advance of the flagger station and transition, based on the posted speed limit and at least equal to or greater than the values in Table 6H-3. Generally speaking, motorists should have a clear line of sight from the graphic flagger symbol sign to the flagger. Option: 3. Where Right -of -Way or geometric conditions prevent the use of 48" x 48" signs. 36" x 36" signs may be used. Standard: 4. Flagging stations shall be located far enough in advance of the work space to permit approaching traffic to reduce speed and/or stop before passing the work space and allow sufficient distance for departing traffic in the left lane to return to the right lane before reaching opposing traffic (see Table 6H-3 on Page 61-11-5). 5. The Flagger (W20-7) symbol sign shall stay within 1/2 mile of each flagger. Guidance: 6. Additional Flagger ymbol signs should be placed at 1 h mile intervals and either erected by the approaching flagger, or taken down as the operation proceeds past this point. 7. When a highway -rail crossing exists within or upstream of the transition area and it is anticipated that queues resulting from the lane closure might extend through the highway -rail grade crossing, the temporary traffic control zone should be extended so that the transition area precedes the highway -rail crossing (see Figure TTC-56 for additional information on highway -rail crossing). 8. If the queue of traffic reaches the BE PREPARED TO STOP (W3-4) sign, then the advance warning signs should be readjusted at greater distances. Standard: 9. All flaggers shall be state certified and have their certification card in their possession when performing flagging duties (see Section 6E.01, Qualifications for Flaggers). 10. A shadow vehicle with at least one amber rotating, flashing or oscillating lights shall be parked 80'-120' in advance of the first work crew. 11. The maximum length of the work area shall be two miles.

Care should be exercised when establishing the limits of the work zone to insure maximum possible sight distance in advance of the flagger station and transition, based on the posted speed limit and at least equal to or greater than the values in Table 6H-3. Generally speaking, motorists should have a clear line of sight from the graphic flagger symbol sign to the flagger. Option: 3. Where Right -of -Way or geometric conditions prevent the use of 48" x 48" signs, 36" x 36" signs may be used. Standard: 4. Flagging stations shall be located far enough in advance of the work space to permit approaching traffic to reduce speed and/or stop before passing the work space and allow sufficient distance for departing traffic in the left lane to return to the right lane before reaching opposing traffic (see Table 6H-3 on Page 61-11-5). 5. All flaggers shall be state certified and have their certification card in their possession when performing flagging duties (see Section 6E.01, Qualifications for Flaggers). 6. Cone spacing shall be based on the posted Speed and the values in Table 6H-4 on Page 61-11-6.1 7. A shadow vehicle with at least one high intensity amber rotating, flashing, or oscillating light shall be parked 80'-120' in advance of the first work crew. Option: 8. A supplemental flagger may be required in this area to give advance warning of the operation ahead by slowing approaching traffic prior to reaching the flagger station or queued traffic. Guidance: 9. If the queue of traffic reaches the BE PREPARED TO STOP (W3-4) sign then the signs, and if used the portable temporary rumble strips (PTRS), should be readjusted at greater distances. 10. When a highway -rail crossing exists within or upstream of the transition area and it is anticipated that queues resulting from the lane closure might extend through the highway -rail grade crossing, the temporary traffic control zone should be extended so that the transition area precedes the highway -rail crossing (see Figure TTC-56for additional information on highway -rail crossings). Standard: 11. At night, flagger stations shall be illuminated, except in emergencies (see Section 6E.08). Option: 12. Cones may be eliminated when using a pilot vehicle operation or when the total roadway width is 20 feet or less. 13. For low-volume situations with short work zones on straight roadways where the flagger is visible to road users approaching from both directions. a single flagger, positioned to be visible to road users approaching from both directions, may be used (see Chapter 6E). Standard: 11. When approved for use, three portable temporary rumble (PTRS) strips shall be installed across the entire travel lane adjacent to the BE PREPARED TO STOP (W3-4) sign. The portable temporary rumble strips shall be monitored and adjusted as necessary during the work shift to ensure proper placement on the roadway. When the PTRS are installed, the RUMBLE STRIPS AHEAD (W2042 sign shall also be utilized.

OF E c 1 North Carolina Division of Energy, Mineral and Land Resources NPDES Stormwater Discharge Permit for Construction Activities Technical Bullentin for NCG010000 Revised Jan. 12, 2017 2 What is this permit? This is your General Stormwater Permit for Construction Activities, developed to meet federal National Pollutant Discharge Elimination System (NPDES) requirements. It is separate and in addition to your Erosion and Sedimentation Control (E&SC) Plan. Federal regulations adopted by the U.S. Environmental Protection Agency (EPA) and N.C. Environmental Management Commission require an NPDES storm- water permit for your project. In North Carolina, the EPA has delegated authority to administer the NPDES program to the Department of Environment and Natural Resources. The E&SC plan approved by the Division of Energy, Mineral and Land (DEMLR), or a delegated local pro- gram, contains the core erosion control requirements for your project. The NPDES Stormwater General Permit contains additional requirements related to a broader range of water quality issues. These permits are related, but separate. Both contain conditions your project site must meet. Are there new requirements in this permit? This General Permit reflects changes made in the federal regulations effective Feb. 1, 2010, that regulate discharges from construction sites. The federal regulations resulted from litigation decisions that mandated construction activities over a certain size must contain additional measures to reduce the amount of wastes and sediment loading that reach the nation's waters. The Department of Environment and Natural Re- sources established the Construction General Permit Technical Advisory Group to guide the development of this NPDES permit. A draft permit was available for public review in May 2011, and the final permit be- came effective on Aug. 3, 2011. The most notable change in the new permit is a requirement that ground stabilization, such as wheat straw application, be applied within 14 days from the last land -disturbing activity. For steep slopes, that area must be stabilized within 7 days. Please see page 2 of this technical bulletin for more details. Do I need to submit a Notice of Intent to have coverage under this permit? No. Your project is covered by this permit upon approval of an adequate erosion and sedimentation control plan that meets requirements for surface dewatering of basins and ground stabilization timeframes. What does this permit require me to do? You should read and become familiar with the provisions of this permit. Below is a list of the major requirements, with indications where those differ from the previous Construction Stormwater General Permit. Erosion and Sediment Control Plan You must implement the E&SC Plan approved for your project by DEMLR or by a delegated local program. Adherence to that E&SC Plan is an enforceable component of this General Permit. Your E&SC plan will identify areas where the more stringent 7- and 14- day ground stabilization requirements apply. See "Ground Stabilization Requirements" on page 2 of this bulletin. Monitoring and Inspections • You must keep a rain gauge on the project site. • Dedicated demolition and other waste areas and earthen material stockpiles must be located at least 50' from storm drains or streams unless no alternative is feasible (new requirement). • You must inspect all E&SC measures at least once a week and within 24 hours after any storm event greater than a half-inch (during a 24-hour period). You must take immediate corrective action for any device failure. • You must inspect all outlets where stormwater runoff leaves the site and evaluate the effect on near -by streams or wetlands. • Corrective action must be taken if sediment is deposited off-site or into a stream or wetland, or causes a visible increase in turbidity (cloudiness) of any waterbody. • You must keep records of these inspections and any corrective actions taken. o � STORMWATER DISCHARGE: STORM WATER DISCHARGES INTO CASCADE CREEK, DRY CREEK, AND SEVERAL UNNAMED TRIBUTARIES ALL DISCHARGE INTO THE LOWER DAN RIVER WHICH IS IN THE ROANOKE RIVER BASIN °IO 0 , 3 Operation and Maintenance You must provide the operation and maintenance necessary to maintain optimal performance of stormwater controls. This means you must take corrective action if erosion and sediment control measures are not operating properly. Operation and maintenance includes, but is not limited to: • Regularly cleaning out sedimentation basins. • Stabilizing eroded banks, channels or spillway structures. • Repairing/clearing out inlets and outlets. • Repairing and maintaining storm drainage inlet and outlet protection. • Repairing piping, seepage and mechanical damage. • Repairing silt fence damage. Reporting The self -inspections required by this permit are an opportunity to identify impacts to nearby waters. If you observe sediment that has deposited in a stream or wetland, you must notify the DEMLR regional office within 24 hours and provide written notice within five days (see item #3 on page six of the General Permit). Non-compliance and Fines Projects that violate Stormwater Permit conditions and/or have un -authorized water quality impacts are subject to fines. Civil penalties of up to $25,000 per day for each violation may be assessed. Inspections Staff from DEMLR and local pro -grams with delegated authority will perform random inspections of your project site to ensure compliance with state and federal regulation governing construction activities. That means that your project, if found to be in violation, could potentially be subject to enforcement action by both DEMLR and the local program. The inspections may be routine in nature or the result of a citizen complaint.

RFPM To reduce erosion and decrease sediment yield from disturbed areas, to permanently stabilize such areas in a manner that is economical, adapts to site conditions, and allows selection of the most appropriate plant materials. Condfflli Where Pracdoe Applies Fine -graded areas on which permanent, long-lived vegetative cover is the most practical or most effective method of stabilizing the soil. Permanent seeding may also be used on rough -graded areas that will not be brought to final grade for a year or more. Areas to be stabilized with permanent vegetation must be seeded or planted within 15 working days or 90 calendar days after final grade is reached, unless temporary stabilization is applied. Plam Consiiderat" Vegetation controls erosion by protecting bare soil surfaces from raindrop impact and by reducing the velocity and volume of overland flow. The most common and economical means of stabilizing disturbed soils is by seeding grasses 9 rasses and legumes. The advantages of seeding over other means of establishing plants include the smaller initial cost, lower labor input, and greater flexibility of method. The disadvantages of seeding include: potential for erosion during the establishment stage, the need to reseed areas that fail to establish, seasonal limitations on suitable seeding dates, and a need for water and appropriate temperatures during germination and early growth. The probability of successful plant establishment can be maximized through good planning, knowledge of the soil characteristics (Table 6.11 a), selection of suitable plant materials for the site, good seedbed preparation, adequate liming and fertilization, and timely planting and maintenance. SELECTING PLANT MATERIALS Climate, soils, and topography are the major factors affecting the suitabilityof plants for articular site. All three of P P these factors vary Y wide) across North Carolina with the most significant contrasts occurring among the three major physiographic regions of the state --Mountains, Piedmont, and Coastal Plain (Figure 6.11a). To simplify plant selection, a Key to Permanent Seeding Mixtures is presented in Table 6.11 b. To find seeding specifications for a specific site, follow this key through the different steps --region, slope, soil, and maintenance level --to theappropriate seedin number. Seeding mixtures 9 9 recommended here are designed for general use and are well proven in practical field situations Table 6.11a Suitability of Soil for Establishment of Low -maintenance Vegetation Criteria Suitability SITE AREA DESCRIPTION Limiting Factors Good Fair Poor 7 days pH 5.6-7.8 4.5-5.5 <4.5 Too acid; possible SIa es steeper than 3:1 P P 7 days If slopes are 10' or less in length and are Al, Mn, Fe toxicity Available >.10 .05-.10 -0.5 Too dry water capacity' All other areas with slopes flatter than 4:1 14 days None, except for perimeters and HOW Zones.

They are designed to produce maximum stabilization and minimize the amount of maintenance and repair required. Land use is a primary consideration in planning permanent seedings. For this purpose land use, whether residential, industrial, commercial, or recreational, can be divided into two general categories: High -maintenance areas are mowed frequently, limed and fertilized regularly, and either (1) receive intensive use (e.g., athletic fields) or (2) require maintenance to an aesthetic standard (e.g., home lawns). Grasses used for these situations are long-lived perennials that form a tight sod and are fine -leaved and attractive in appearance. They must be well -adapted to the geographic area where they are planted and able to endure the stress of frequent mowing. Sites where high -maintenance vegetative cover is desirable include homes, industrial parks, schools, churches, and recreational areas. Low -maintenance areas are mowed infrequently or not at all, and do not receive lime and fertilizer on a regular basis. Plants must persist with little maintenance over long periods of time. Grass and legume mixtures are favored for these sites because legumes are a source of soil nitrogen. Mixed stands are also more resistant to adverse conditions. Sites suitable for low -maintenance vegetation include steep slopes, stream or channel banks, some commercial properties, and "utility" turf areas such as roadbanks. SEEDBED PREPARATION The soil on a disturbed site must be amended to provide an optimum environment for seed germination and seedling growth. The surface soil must be loose enough for water infiltration and root penetration. The pH (acidity or alkalinity) of the soil must be such that it is not toxic and nutrients are available --preferably between 6.0 and 6.5. Sufficient nutrients --added as fertilizer --must be present. It is as important to add lime as to add fertilizer. Lime is used primarily as a pH, or acidity modifier, but it also supplies calcium and magnesium, which are important plant nutrients. By increasing soil pH, it also makes other nutrients more available to plants. At the same time, it prevents aluminum toxicity by decreasing the solubility of soil aluminum. Many soils in North Carolina are high in aluminum, which stunts plant growth. After seed is in place, it must be protected with a mulch to hold moisture and modify temperature extremes, while preventing erosion during seedling establishment. STEEP SLOPES The operation of equipment is restricted on slopes steeper than 3:1, severely limiting the quality of the seedbed that can be prepared. The soil cannot be sufficiently worked, and amendments cannot be thoroughly incorporated. Provisions for establishment of vegetation on steep slopes can be made during final grading. In construction of fill slopes, for example, the last 4-6 inches might be left uncompacted. A loose, rough seedbed is essential. Large clods and stones provide irregularities that hold seeds and fertilizer. Cut slopes should be roughened (Practice 6.03, Surface Roughening). Where steepness prohibits the use of farm machinery, seeding methods are limited to broadcast or hydroseeding, with hydroseeding giving the most dependable results. Vegetation chosen for these slopes must not require mowing or other intensive maintenance. Using a hydraulic seeder, seed, fertilizer, wood fiber mulch, and a tacking agent can be applied in one operation. Good mulching practices are critical to protect against erosion on steep slopes. When using straw, anchor with netting or asphalt. On slopes steeper than 2:1, a rolled erosion control product may be required to protect the slope. Specifications ter SEEDBED REQUIREMENTS Establishment of vegetation should not be attempted on sites that are unsuitable due to inappropriate soil texture (Table 6.11 a), poor drainage, concentrated overland flow, or steepness of slope until measures have been taken to correct these problems. To maintain a good stand of vegetation, the soil must meet certain minimum requirements as a growth medium. The existing soil should have these criteria: Enough fine-grained (silt and clay) material to maintain adequate moisture and nutrient supply (available water capacity of at least .05 inches of water to 1 inch of soil). Sufficient pore space to permit root penetration. Sufficient depth of soil to provide an adequate root zone. The depth to rock or impermeable layers such as hardpans should be 12 inches or more, except on slopes steeper than 2:1 where the addition of soil is not feasible. A favorable pH range for plant growth, usually 6.0-6.5. Freedom from large roots, branches, stones, large clods of earth, or trash of any kind. Clods and stones may be left on slopes steeper than 3:1 if they are to be hydroseeded. If any of the above criteria are not met--i.e., if the existing soil is too coarse, dense, shallow, or acidic to foster vegetation --special amendments are required. The soil conditioners described below may be beneficial or, preferably, topsoil may be applied in accordance with Practice 6.04, Topsoiling. SOIL CONDITIONERS In order to improve the structure or drainage characteristics of a soil, the following materials may be added. These amendments should only be necessary where soils have limitations that make them poor for plant growth or for fine turf establishment (see Chapter 3, Vegetative Considerations). Peat --Appropriate types are sphagnum moss peat, hypnum moss peat, reed -sedge peat, or peat humus, all from fresh -water sources. Peat should be shredded and conditioned in storage piles for at least 6 months after excavation. Sand --clean and free of toxic materials. Vermiculite--horticultural9 rade and free of toxic substances. Rotted manure --stable or cattle manure not containing undue amounts of straw or other bedding materials. Thoroughly rotted sawdust --free of stones and debris. Add 6 Ib of nitrogen to each cubic yard. Sludge --Treated sewage and industrial sludges are available 9 9 9 in various forms; these should be used only in accordance with local, State, and Federal regulations. SPECIES SELECTION Use the Ke to Permanent Seeding Mixtures Table 6.11 b to Y 9 ( ) select the most appropriate seeding mixture based on the general site and maintenance factors. A listing of species, including scientific names and characteristics, is given in Appendix 8.02. SEEDBED PREPARATION Install necessary mechanical erosion and sedimentation control practices before seeding, and complete grading according to the approved plan. Lime and fertilizer needs should be determined by soil tests. Soil testing is performed free of charge by the North Carolina Department of Agriculture soil testing laboratory. Directions, sample cartons, and information sheets are available through county Agricultural Extension offices or from NCDA. Because the NCDA soil testing lab requires 1-6 weeks for sample turn -around, sampling must be planned well in advance of final grading. Testing is also done by commercial laboratories. When soil tests are not available, follow rates suggested on the individual specification sheet for the seeding mix chosen (Tables 6.11 c through 6.11v). Application rates usually fall into the following ranges: Ground agricultural limestone: Light -textured, sandy soils: 1- 1 1/2 tons/acre Heavy textured, clayey soils: 2-3 tons/acre Fertilizer: Grasses: 800-1200 Ib/acre of 10-10-10 (or the equivalent) Grass -legume mixtures: 800-1200 Ib/acre of 5-10-10 (or the equivalent) Apply lime and fertilizer evenly and incorporate into the top 4-6 inches of soil by disking or other suitable means. Operate machinery on the contour. When using a hydroseeder, apply lime and fertilizer to a rough, loose surface. Roughen surfaces according to Practice 6.03, Surface Roughening. Complete seedbed preparation by breaking up large clods and raking into a smooth, uniform surface (slopes less than 3:1). Fill in or level depressions that can collect water. Broadcast seed into a freshly loosened seedbed that has not been sealed by rainfall. SEEDING Seeding dates given in the seeding mixture specifications (Table 6.11c through 6.11v) are designated as "best" or "possible". Seedings properly carried out within the "best" dates have a high probability of success. It is also possible to have satisfactory establishment when seeding outside these dates. However, as you deviate from them, the probability of failure increases rapidly. Seeding on the last date shown under "possible" may reduce chances of success by 30-50%. Always take this into account in scheduling land -disturbing activities. Use certified seed for permanent seeding whenever possible. Certified seed is inspected by the North Carolina Crop Improvement Association. It meets published North Carolina Standards and should bear an official "Certified Seed" label (Figure 6.11 b). Figure 6.11 b Label displayed on all North Carolina certified seed. Labeling of non -certified seed is also required by law. Labels contain important information on seed purity, germination, and presence of weed seeds. Seed must meet State standards for content of noxious weeds. Do not accept seed containing "prohibited" noxious weed seed. Inoculate legume seed with the Rhizobium bacteria appropriate to the species of legume (Chapter 3, Vegetative Considerations). Apply seed uniformly with a cyclone seeder, drop -type spreader drill, cultipacker seeder, or hydroseeder on a firm, friable seedbed. When using a drill or cultipacker seeder, plant small grains no more than 1 inch deep, grasses and legumes no more than 1/2 inch. Equipment should be calibrated in the field for the desired seeding rate. When using broadcast -seeding methods, subdivide the area into workable sections and determine the amount of seed needed for each section. Apply one-half the seed while moving back and forth across the area, making a uniform pattern; then apply the second half in the same way, but moving at right angles to the first pass (Figure 6.11 c). Figure 6.11 c Suggested pattern for broadcasting seed and fertilizer (source: NCAES Bulletin AG -69). Cover broadcast seed by raking or chain dragging; then firm the surface with a roller or cultipacker to provide good seed contact. Mulch all plantings immediately after seeding (Practice 6.14, Mulching). HYDROSEEDING Surface roughening is particularly important when hydroseeding, as a roughened slope will provide some natural coverage for lime, fertilizer, and seed. The surface should not be compacted or smooth. Fine seedbed preparation is not necessary for hydroseeding operations; large clods, stones, and irregularities provide cavities in which seeds can lodge. Rate of wood fiber (cellulose) application should be at least 2,000 Ib/acre. Apply legume inoculants at four times the recommended rate when adding inoculant to a hydroseeder slurry. If a machinery breakdown of 1/2 to 2 hours occurs, add 50% more seed to the task, based on the proportion of the slurry remaining. This should compensate for damage to seed. Beyond 2 hours, a full rate of new seed may be necessary. Lime is not normally applied with a hydraulic seeder because it is abrasive. It can be blown onto steep slopes in dry form. 2 TABLE 6.110 SEEDING NO. 5P FOR: GRASS -LINED CHAN N E LSPraCtiCe Standards an SpecifIcations Seeding mixture Species, Tall fescue Rate (lblacre) 200 (4-5 lb/1,000 tt2) Nurse plants Between May 1 and Aug, 15 add 15lb/acre Sudangrass or 10 lb/acre Ger- man millet.

To temporarily stabilize denuded areas that will not be brought to final grade for a period of more than 21 calendar days. Temporary seeding controls runoff and erosion until permanent vegetation or other erosion control measures can be established. In addition, it provides residue for soil protection and seedbed preparation, and reduces problems of mud and dust production from bare soil surfaces during construction. Conditions Where PractW Applies On any cleared, unvegetated, or sparsely vegetated soil surface where vegetative cover is needed for less than 1 year. Applications of this practice include diversions, dams, temporary sediment basins, temporary road banks, and topsoil stockpiles. Considerations Annual plants, which sprout and grow rapidly and survive for only one season, are suitable for establishing initial or temporary vegetative cover. Temporary seeding preserves the integrity of earthen sediment control structures such as dikes, diversions, and the banks of dams and sediment basins. It can also reduce the amount of maintenance associated with these devices. For example, the frequency of sediment basin cleanouts will be reduced if watershed areas, outside the active construction zone, are stabilized. Proper seedbed preparation, selection of appropriate species, and use of quality seed are as important in this Practice as in Practice 6.11, Permanent Seeding. Failure to follow established guidelines and recommendations carefully may result in an inadequate or short-lived stand of vegetation that will not control erosion. Temporary seeding provides protection for no more than 1 year, during which time permanent stabilization should be initiated. S tions Complete grading before preparing seedbeds, and install all necessary erosion control practices such as, dikes, waterways, and basins. Minimize steep slopes because they make seedbed preparation difficult and increase the erosion hazard. If soils become compacted during radio loosen them to a P 9 9 9. depth of 6-8 inches using a ripper, harrow, or chisel plow. SEEDBED PREPARATION Good seedbed preparation is essential to successful plant establishment. A good seedbed is well -pulverized, loose, and uniform. Where hydroseeding methods are used, the surface may be left with a more irregular surface of large clods and stones. Liming --Apply lime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone at the 6.10 6 rate of 1 to 1 1/2 tons/acre on coarse-textured soils and 2-3 tons/acre on fine -textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil. Soils with a pH of 6 or higher need not be limed. Fertilizer --Base application rates on soil tests. When these are not possible, apply a 10-10-10 grade fertilizer at 700-1,000 Ib/acre. Both fertilizer and lime should be incorporated into the top 4-6 inches of soil. If a hydraulic seeder is used, do not mix seed and fertilizer more than 30 minutes before application. Surface roughening --If recent tillage operations have resulted in a loose surface additional roughening not be 9 9 ma Y required, except to break up large clods. If rainfall causes the surface to become sealed or crusted, loosen it just prior to seeding by disking, raking, harrowing, or other suitable methods. Groove or furrow slopes steeper than 3:1 on the contour before seeding(Practice 6.03, Surface Roughening). PLANT SELECTIN Select an appropriate species or species mixture from Table 6.10a for seeding in late winter and early spring, Table 6.10b for summer, and Table 6.10c for fall. In the Mountains, December and January seedings have poor chances of success. When it is necessary to plant at these times, use recommendations for fall and a securely tacked mulch. SEEDING Evenly apply seed using a cyclone seeder (broadcast), drill, cultipacker seeder, or hydroseeder. Use seeding rates given in Tables 6.10a -6.10c. Broadcast seeding and hydroseeding are appropriate for steep slopes where equipment cannot be driven. Hand broadcasting is not recommended because of the difficulty in achieving a uniform distribution. Small grains should be planted no more than 1 inch deep, and grasses and legumes no more than 1/2 inch. Broadcast seed must be covered by raking or chain dragging, and then lightly firmed with a roller or cultipacker. Hydroseeded mixtures should include a wood fiber (cellulose) mulch. MULCHING The use of an appropriate mulch will help ensure establishment under normal conditions, and is essential to seeding success under harsh site conditions (Practice 6.14, Mulching). Harsh site conditions include: seeding in fall for winter cover (wood fiber mulches are not considered adequate for this use), slopes steeper than 3:1, excessively hot or dry weather, adverse soils (shallow, rocky, or high in clay or sand), and areas receiving concentrated flow. If the area to be mulched is subject to concentrated waterflow, as in channels, anchor mulch with netting (Practice 6.14, Mulching). 6.10.2 Practice ftrKW& and SpecIlImtbns Makftrlarim Reseed and mulch areas where seedling emergence is poor, or where erosion occurs, as soon as possible.

Examples of RECP's are blankets, nets, and matting. Purpose Erosion control mats and blankets are intended to protect soil and hold seed and mulch in place on slopes and in channels so that vegetation can become well established. Turf reinforcement mats can be used to permanently reinforce grass in drainage ways during high flows. Nets are made of high tensile material woven into an open net which overlays mulch materials. Blankets are made of interlocking fibers, typically held together by a biodegradable or photodegradable netting (for example, excelsior or straw blankets). They generally have lower tensile strength than nets, but cover the ground more completely. Coir (coconut fiber) fabric comes as both nets and blankets. Conditions Where Practice Applies Rolled Erosion Control Products (RECP's) should be used to aid permanent vegetated stabilization of slopes 2:1 or greater and with more than 10 feet of vertical relief. RECP's should also be used when mulch cannot be adequately tacked and where immediate ground cover is required to prevent erosion damage. RECP's should be used to aid in permanent stabilization of vegetated channels when runoff velocity will exceed 2 ft/sec on bare earth during the 2 -year rainfall event that produces peak runoff. The product selected must have a permissible shear stress that exceeds the shear stress of the design runoff event. Maintenance 1. Inspect Rolled Erosion Control Products at least weekly and after each significant P Y 9 (1/2 inch or greater) rain fall event repair immediately. 2. Good contact with the ground must be maintained, and erosion must not occur beneath the RECP. 3. Any areas of the RECP that are damaged or not in close contact with the ground shall be repaired and stapled. 4. If erosion occurs due to poorly controlled drainage, the problem shall be fixed and the eroded area protected. 5. Monitor and repair the RECP as necessary until ground cover as established.

CONDITIONS WHERE THIS PRACTICE MAY BE USED AS A TEMPORARY OR EMERGENCY PRACTICE APPLIES MEASURE TO LIMIT EROSION BY REDUCING FLOW IN SMALL OPEN CHANNELS. LIMIT DRAINAGE TO 2 ACRES OR LESS. DO NOT USE CHECK DAMS IN LIVE STREAMS. CONSTRUCTION 1. PLACE STONE AT THE LOCATION SHOWN ON THE PLAN ON A FILTER SPECIFICATIONS FABRIC FOUNDATION. 2. KEEP THE CENTER STONE SECTION AT LEAST 9 INCHES BELOW NATURAL GROUND LEVEL WHERE THE DAM ABUTS THE CHANNEL BANKS. 3. EXTEND STONE AT LEAST 1.5 FT. BEYOND THE DITCH BANKS (FIG. 6.83b) TO KEEP OVERFLOW WATER FROM UNDERCUTTING THE DAM AS IT RE-ENTERS THE CHANNEL. 4. SET SPACING BETWEEN DAMS TO ASSURE THAT THE ELEVATION AT THE TOP OF THE LOWER DAM IS THE SAME AS THE TOE ELEVATION OF THE UPPER DAM. 5. PROTECT THE CHANNEL DOWNSTREAM FROM THE LOWEST CHECK DAM, CONSIDERING THAT WATER WILL FLOW OVER AND AROUND THE DAM. 6. MAKE SURE THAT THE CHANNEL REACH ABOVE THE MOST UPSTREAM DAM IS STABLE. 7. ENSURE THAT CHANNEL APPURTENANCES, SUCH AS CULVERT ENTRANCES BELOW CHECK DAMS, ARE NOT SUBJECT TO DAMAGE OR BLOCKAGE FROM DISPLACED STONES. MAINTENANCE: INSPECT CHECK DAMS AND CHANNELS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (1/2" OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. CLEAN OUT SEDIMENT, STRAW, LIMBS OR OTHER DEBRIS THAT COULD CLOG THE CHANNEL WHEN NEEDED. ANTICIPATE SUBMERGENCE AND DEPOSITION ABOVE THE CHECK DAM AND EROSION FROM HIGH FLOWS AROUND THE EDGES OF THE DAM. CORRECT ALL DAMAGE IMMEDIATELY. IF SIGNIFICANT EROSION OCCURS BETWEEN DAMS, ADDITIONAL MEASURES CAN BE TAKEN SUCH AS INSTALLING A PROTECTIVE RIP RAP LINER IN THAT PORTION OF THE CHANNEL.

This practice allows early use of the storm drainage system. Conditlons Where PMC*M Applies Rock pipe inlet protection may be used at pipes with a maximum diameter of 36 inches. This inlet protection may be used to supplement additional sediment traps or basins at the pipe outlet, or used in combination with an excavated sediment storage area to serve as a temporary sediment trap. Pipe inlet protection should be provided to protect the storm drainage system and downstream areas from sedimentation until permanent stabilization of the disturbed drainage area. Do not install this measure in an intermittent or perennial stream. Plaming Conekleratkm8 When construction on a project reaches a stage where culverts and other storm drainage structures are installed and many areas are brought to the desired grade, there is a need to protect the points where runoff can leave the site through culverts or storm drains. Similar to drop and curb inlets, culverts receiving runoff from disturbed areas can convey large amounts of sediment to lakes or streams. Even if the pipe discharges into a sediment trap or basin, the pipe ttorr� pipe system itself may clog with sediment. piI om When used in combination with an excavated sediment storage area to serve as a temporary sediment trap, the design criteria for temporary sediment traps must be satisfied. The maximum drainage area should be 5 acres, and 3600 cubic feet of sediment storage per acre of disturbed drainage area should be provided. The minimum stone height should be 2 feet, with side slopes no steeper than 2:1. The stone "horseshoe" around the pipe inlet should be constructed of Class B or Class I riprap, with a minimum crest width of 3 feet. The outside face of the riprap should be coved with a 12 -inch thick layer of #5 or #57 washed stone. In preparing plans for rock pipe inlet protection, it is important to protect the embankment over the pipe from overtopping. The top of the stone should be a minimum of 1 foot below the top of the fill over the pipe. The stone should tie into the fill on both sides of the pipe. The inside toe of the stone should be no closer than 2 feet from the culvert opening to allow passage of high flows. The sediment storage area should be excavated upstream of the rock pipe inlet protection, with a minimum depth of 18 inches below grade.

Maintenance Inspect rock pipe inlet protection at least weekly and after each significant (% 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 the stone horseshoe must be replaced immediately. After all the sediment -producing areas have been permanently stabilized, remove the structure and all the unstable sediment.

PLANTS SHALL NOT BE HANDLED BY THE STEMS DURING TRANSPORT TO PLANTING SITE OR DURING PLANTING. 8. IF AN EROSION CONTROL BLANKET IS PRESENT, A CIRCULAR OPENING SHALL BE CUT IN THE BLANKET PRIOR TO EXCAVATION OF THE PIT. 9. NON -BIODEGRADABLE MATERIAL SURROUNDING THE EARTHEN BALL OF THE PLAN SHALL BE REMOVED PRIOR TO BACKFILLING OF THE PIT. 10. TO SET THE PLANTS, PREPARE ALIGNMENT OF INDIVIDUAL TREE SAPLINGS PLUMB AND STRAIGHT AND PROVIDE ALLOWANCE FOR SETTLEMENT. 11. BACKFILL THE PLANTING HOLES WITH IN-SITU SOIL MATERIALS REMOVED FOR PLANTING. 12. AFTER BACKFILLING, WATER TO THE POINT OF SOIL SATURATION AND TAMP TO COMPACT THE BACKFILL MIXTURE. ADD EXISTING SOIL TO BRING THE FINAL GRADE IN THE PLANTING HOLE TO THE SURROUNDING SOIL SURFACE. RAKE THE UNUSED SOIL OUTSIDE THE PLANTING HOLES, TAKING CARE NOT TO MOUND THE SOIL OR TO SIGNIFICANTLY ALTER THE EXISTING GRADES. 13. THE CONTRACTOR SHALL BE RESPONSIBLE FOR MAINTAINING 80% SURVIVABILITY THROUGH THE FIRST YEAR AFTER CONSTRUCTION. AS -BUILT, VEGETATIVE MONITORING AND GEOMORPHOLOGICAL MONITORING WILL BE COMPLETED WITHIN 60 DAYS AFTER CONSTRUCTION COMPLETION. 14. TREES, SHRUBS AND LIVE STAKE PLANTING IS TO OCCUR BETWEEN NOVEMBER 15 AND MARCH 15, DURING DORMANCY. LIVE STAKES SHOULD ONLY BE USED WITHIN THE AREA WHERE ADEQUATE DRAINAGE AND SOIL SATURATION WILL INDUCE ADEQUATE ROOT GROWTH. LIVE STAKES SHALL HAVE A MINIMUM DIAMETER OF 1/2 INCHES AND A MINIMUM OF LENGTH 24 INCHES. SOAK THE STAKE FOR 24 HOURS. CUT ENDS AT A 45° ANGLE PRIOR TO INSTALLATION. DRIVE STAKE INTO THE GROUND TO 3/4 OF ITS LENGTH, AT A 45° IN THE DOWNSTREAM DIRECTION. 15. THE SUPPLIER OF ALL SEEDS AND/OR VEGETATION SHALL CERTIFY THAT THE ORIGIN OF THE SEEDS FROM WHICH THE PLANTS OR SEEDS WERE PRODUCED IS FROM HARDINESS ZONES 7A AND 7B, EAST OF TENNESSEE, AND AS DIRECTED BY THE SPECIAL PROVISIONS. 16. ALL PLANTS SHALL BE CONSERVATION GRADE, FIRST CLASS REPRESENTATIVES OF THEIR SPECIES, NURSERY GROWN ACCORDING TO GOOD HORTICULTURE PRACTICES AND GROWN IN A CLIMATE SIMILAR TO THE PROJECT AREA. PLANTS SHALL BE VIGOROUS, HEALTHY AND FREE OF DISEASE, INSECTIVOROUS PESTS, DECAY, INJURIES AND ALL FORMS OF OBJECTIONABLE DISFIGUREMENTS. TRUNKS AND BRANCHES SHALL BE FREE OF CUTS AND ABRASIONS. PLANTS SHALL CONFORM TO ALL ASPECTS OF THE CURRENT EDITION OF THE AMERICAN STANDARD FOR NURSERY STOCK (ANSI Z60.1) FOR CONSERVATION GRADE PLANT MATERIAL. 17. TREES AND SHRUBS SHALL BE PLANTED ON 10 FT CENTERS. LIVE STAKES SHALL BE PLANTED IN GROUPS WHERE PLANS SHOW ON 4 FT CENTERS. A COMBINATION OF BARE ROOT AND PLUG PLANTS SHOULD BE PLANTED IN CONJUNCTION WITH THE APPLIED WETLAND VARIETY SEED MIX IN ORDER TO CREATE A NATURALIZED STREAM BANK AND TO ESTABLISH ADEQUATE VEGETATIVE COVER TO PREVENT SLOUGHING AND EROSION OF THE BANK. 18. THE SELECTED WETLAND SEED MIX SHALL BE SURFACE SOWN AT THE RATE OF 150 LBS/ACRE TO ALL DISTURBED AREAS ALONG THE EASEMENT. 19. ALL BARE ROOT SEEDLINGS OR PLUGS SHALL BE PLANTED IN SUCH A MANNER AS TO ENSURE THEIR SURVIVAL. THIS SHALL INCLUDE THE PLANTING OF INTACT ROOTS, PLANTING AT PROPER DEPTH, PROPER BACKFILLING AND WATERING. 20. IN AREAS WHERE THE RESTORATION DESIGN REQUIRES SLOPES TO BE CUT BACK AND GRADED, SLOPES SHALL BE SCARIFIED APPROXIMATELY 4 TO 6 INCHES BELOW THE SURFACE PRIOR TO PLANTING. BIODEGRADABLE EROSION CONTROL MAT SHALL BE USED IN ALL AREAS. AN OPENING SHALL BE CUT IN THE MAT FOR EACH PLANTING PRIOR TO INSTALLATION. BARE ROOT SEEDLINGS OR PLUGS SHALL BE PLANTED AND THE ENTIRE AREA SHALL BE TOP DRESSED WITH A WETLAND SEED MIX. 21. BARE ROOT SEEDLINGS OR PEAT POTS THAT ARE TO BE SELECTED FROM THE PLANTING SPECIES LIST ON THIS SHEET SHALL BE PLANTED IN MONOSPECIFIC GROUPS USING A 2 -FOOT ON CENTER SPACING WITHIN THE GROUP TO A MAXIMUM NUMBER OF 50 PLANTS PER GROUP.
