THE DRAINAGE AREAS AND LAND COVER CONDITION ARE GENERALLY CONSISTENT BETWEEN PRE -DEVELOPMENT (GOLF COURSE) AND POST-DEVELOPMETN (GOLF COURSE). THE CUMULATIVE DRAINAGE AREA IS CONSTANT AND THE CURVE NUMBER OF THE SITE AREA HAS DECREASED FROM PRE AND POST -DEVELOPMENT CONDITIONS. OUTFALL1: AN ONSITE NATURAL CHANNEL CONVEYS RUNOFF FROM THE SITE TO MOREY CREEK. THE DRAINAGE AREA WITHIN THIS OUTFALL IS GENERALLY UNDISTURBED -AN EXISTING GOLF COURSE (TURF) AREA WILL BE CONVERTED TO A MEADOW (BRUSH). OUTFALL 2: A LARGE ONSITE POND (#2) SERVES A MAJORITY OF THE DRAINAGE AREA TO THE OUTFALL. SOME AREAS WITHIN THIS OUTFALL ARE CONVERTED FROM GOLF COURSE TO MEADOW, WHILE OTHER AREAS ARE CONVERTED FROM BRUSH TO GOLF COURSE. THE OUTFALL IS A NATURAL CHANNEL FROM THE POND (#2) TO MOREY CREEK. OUTFALL 3: A LARGE ONSITE POND (#3) SERVES A MAJORITY OF THE DRAINAGE AREA TO THE OUTFALL. THE UPSTREAM AND DOWNSTREAM NATURAL CHANNELS HAVE STREAM BUFFERS, WITH SOME AREAS BEING USED FOR MITIGATION (CONVERSION TO FOREST). THE OUTFALL IS A NATURAL CHANNEL FROM THE POND (#3) TO MOREY CREEK. OUTFALL 4: THIS OUTFALL POINT IS A NATURAL CHANNEL, BUT DOES NOT HAVE AN UPSTREAM STORMWATER MANAGEMENT SYSTEM. WORK WITHIN THIS DRAINAGE AREA IS GENERALLY LIMITED TO REDEVELOPMENT WITH MINIMAL CHANGE IN LAND COVER CONDITIONS. OUTFALL 5: AN ONSITE POND (#3) SERVES A MAJORITY OF THE DRAINAGE AREA TO THE OUTFALL, BEFORE THE RUNOFF IS CONVEYED TO A NATURAL CHANNEL. OUTFALLS 6/718: THESE OUTFALL POINTS EXIST ALONG THE EASTERN SIDE OF THE PROPERTY LINE. RUNOFF FROM THE SITE IS NOT CONCENTRATED BEFORE LEAVING THE SITE, BUT IS CONVEYED TOWARDS MOREY CREEK. :_ — -;e � ; — SOIL DIVIDES Emmmmmm DRAINAGE DIVIDES LIMITS OF VVORK SCALE 1"=300' 360' 600' A.

NIaintenanee Agreements Section 4 VAC 50-60-124 of the regulations specifies the circumstances iulder which- a maintenance agreement must be executed between the owner and the local prograrn. This section sets forth inspection requirements, corrrpliance procedures if txraintenance is neglected, notification of the local program upon transfer of ownership, and right -of -entry for local program personnel. All Vegetated Filter Strips must be covered by a drainage casement to allow inspection and maintenance:. If the filter area is a natural Conserved Open Space, it must be protected by a perpetual easement or deed restriction that assigns the responsible party to ensure that no future development, disturbance or clearing. may occur within the area, except as stipulated in the vegetation.maintenance plan_ If the Vegetated Filter Strip is located on a residential private lot, the existence and purpose of the Filter Strip shall be noted on the deet( of record. Rotneowners will need to be provided a simple document that explains the purpose of the Filter Strip and routine maintenance needs. A deed restriction or other mechanism enforceable by the qualifying local program. must be in place to help ensure that Filter Strips are maintained and Conserved Open. Space Areas are not converted: or disturbed, The mechanism should, if possible, grant authority for local agencies to access the property for inspection or corrective action. 9.2. Maintenance Inspections Annual inspections are used to trigger maintenance Operations such as sediment removal, spot re - vegetation and levet spreader repair. Ideally, inspections should be conducted in the .non -growing season when it easier to see the flow path. Example maintenance inspection checklists for Sheet Flow to a Filter Strip or Conserved Open Space areas can be accessed in Appendix C of Chapter 9 of the Virginia Stormwater Management Landbook or at the Center for Watershed Protection's website at: tett :// vww.cw,vr /Resource Library/Controlling Runoff and Discharges/sm.htm (scroll to Too16 Plan Review, BMP Construction, and Maintenance C=hecklists) Inspectors should cheek to ensure that: • Flows through the Filter Strip do not short-circuit the overflow control section; • Debris and sediment does not build up at the top of the Filter Strip; • Foot or vehicular traffic does not compromise the gravel diaphragm; • Scour and erosion do not occur within the :Filter Strip; • Sediments are cleaned out of Level Spreader forebays and flow splitters; and • Vegetative density exceeds a 90% cover in the boundary zorie or grass filter.

Compost amendments can be applied to the entire pervious area of a development or be applied only to select areas of the site to enhance the performance of runoff reduction practices. Some common design applications include: • Reduce runoff from compacted lawns. • Enhance rooftop disconnections on poor soils. • Increase runoff reduction within a grass channel. • Increase runoff reduction within a vegetated filter strip. + Increase the runoff reduction function. of a tree cluster or reforested area of the site. SECTION 6: DESIGN CRITERIA 6.1. Performance When Used in Conjunction With Other Practices As referenced in. several of the other specifications, soil compost amendments can be used to enhance the runoff reduction capabilities of allied practices. The specifications for each of these practices contain design criteria for how compost amendments can be incorporated into those designs: • Rooftop (impervious) Disconnection - see Stormwater Design Specification No. 1, Section 3.2. • Vegetated Filter Strips - see Stormwater Design Specification No. 2, Section 6.1. • Grass Channels -- see Stormwater Design Specification No. 3, Section 6.5. • Site Reforestation - see Appendix A of this design specification. 6.2. Soil Testing Soil tests are required during two stages of the compost amendment process. The first testing is done to ascertain pre -construction soil properties at proposed amendment areas. The initial testing is used to determine soil properties to a depth 1 foot below the proposed amendment area, with respect to bulk density, pH, salts, and soil nutrients. These tests should be conducted every 5000 square feet, and are used to characterize potential drainage problems and determine what, if any, further soil amendments are needed. Version 1.8, March 1, 2011 VA IDEA STORMWATER DESIGN SPECIFICATION NO.4 Page 3 of 10 SOIL COMPOST AMENDMENT h. Carbon/nitrogen ratio shall be less than 25:1 i.Trace metal test result = "pass" j. The compost must have a dry bulk density ranging from 40 to 50 lbs./cu. ftp. SECTION 7: REGIONAL & SPECIAL CASE DESIGN ADAPTATIONS 7.1. Karst Terrain No special adaptations are needed in karst terrain, but the designer should take soil tests to ensure that soil pH is adjusted to conform to pre-existing soil conditions found in limestone dominated areas. 7.2. Coastal Plain Designers should evaluate drainage and water table elevations to ensure the entire depth of soil amendment will not become saturated (i.e., a minimum separation depth of 2 feet from groundwater). Compost amendments are most cost effective when used to boost the runoff reduction capability of grass vegetated filter strips, grass channels and rooftop disconnections. 7.3. Steep Terrain Compost amendments are ineffective when longitudinal slopes exceed 5%, so some terracing may be needed on steeper slopes. 7.4. Cold Climate and Winter Performance Soil restoration is not recommended for areas that will be used for snow storage. 7.5. Linear Highway Sites Soil amendments can improve the runoff reduction of drainage swales in open section rights-of- way and highway medians. SECTION 8: CONSTRUCTION 8.1. Construction Sequence The construction sequence for compost amendments differs depending whether the practice will be applied to a large area or a narrow filter strip, such as in a rooftop disconnection or grass channel. For larger areas, a typical construction sequence is as follows: Step 1. Prior to building, the proposed area should be deep tilled to a depth of 2 to 3 feet using a tractor and sub-soiler with two deep shanks (curved metal bars) to create rips perpendicular to the direction of flow. (This step is usually omitted when compost is used for narrower filter strips.) Version 1.8, March 1, 2011 Page 6 of 10 VA DEQ STORMWATER DESIGN SPECIFICATION NO.4 SOIL COMPOST AMENDMENT The second soil test is taken at least one week after the compost has been incorporated into the soils. This soil analysis should be conducted by a reputable laboratory to detennine whether any further nutritional requirements, pH adjustment, and organic matter adjustments are necessary for plant growth.. This soil analysis should be done in conjunction with the final construction inspection to ensure tilling or subsoiling has achieved design depths. 6.3. Runoff Volume Reduction The runoff volume reduction achieved by soil restoration depends on the site application and the pre -construction hydrologic soil group. When compost amendments are used simply to reduce runoff volume from compacted lawns, the lower runoff coefficients shown in Table 4.2 can be used to lower the total treatment volume for the site as a whole. If the soil restoration area accepts runoff from adjacent impervious areas, the higher runoff reduction rates outlined in Table 4.1 above may be used for the indicated practices. Table 4.2. Runoff Coefficients for Use for Different Pervious Areas A 402 0.15 0.02 B 0.03 0.20 0.03 C 0.04 0.22 0.04 D 0.05 0.25 405 Notes: Portions of a new development site, outside the limits of disturbance, which are not graded and do not receive construction traffic. 2 Previously developed sites, and any site area inside the limits of disturbance as shown on the E&S Control plan. 3 Areas with restored soils that are also reforested to achieve a minimum 75% forest 6.4. Determining Depth of Compost Incorporation The depth of compost amendment is based on the relationship of the surface area of the soil amendment to the contributing area of impervious cover that it receives. Table 4.3 presents some gerieral guidancederived from soil modeling by Holman -Dodds (2004) that evaluates the required depth to which compost must be incorporated. Some adjustments to the recommended incorporation depth were made to reflect alternative recommendations of Roa Espinosa (2006), Balousek (2003), Chollak and Rosenfeld (;1998) and others. Version 1.8, March 1, 2011 Page 4 of 10 VA DEQ STORMWATER DESIGN SPECIFICATION NO. 4 SOIL COMPOST AMENDMENT Step 2. A second deep tilling to a depth of 12 to 1.8 inches is needed after final building lots have been graded. Ship 3. It is important to have dry conditions at the site prior to incorporating compost. Step 4. An acceptable compost mix is then incorporated into the soil using a roto -tiller or similar equipment it the volumetric rate of 1 part compost to 2 parts soil. Step S. The site should be leveled and seeds or sod used to establish a vigorous grass cover. Lime or urrigation may initially be needed to help the grass grow quickly. Step 6. Areas of compost amendments exceeding 2500 square feet should employ simple erosion control measures, such as silt fence, to reduce tlie potential for erosion and trap sediment. 8.1. Construction Inspection Construction inspection involves digging a test pit to verify the depth of mulch, amended soil and scarification. A rod penetrometer should be used to establish the depth of uncompacted soil at one location per 10,000 square feet. SECTION 9: MAINTENANCE 9.1. Maintenance Agreements When soil compost amendments are applied on private residential lots, homeowners will need to be educated on their routine maintenance needs, understand the long-term maintenance plan, and be subject to a deed restriction or other mechanism enforceable by the qualifying local program to ensure that infiltrating areas are not converted or disturbed. The mechanism should, ideally, grant authority for local agencies to access the property for inspection or corrective action. In addition, the GPS coordinates for all amended areas should be provided upon facility acceptance to ensure long terin tracking. A simple maintenance agreement should be provided if soil restoration is associated with more than 10,000 square feet of reforestation. A conservation easement or deed restriction, which also identifies a responsible party, may be required to make sure the newly developing forest cannot be cleared or developed management is accomplished (i.e., thinning, invasive plant removal, etc.). Soil compost amendments within a filter strip or grass channel should be located in a public right-of=way, or within a dedicated stormwater or drainage easement. 9.2. First Year Maintenance Operations In. order to ensure the success of soil compost amendments, the following tasks must be undertaken in the first year following soil restoration: Initial inspections. For the first six months following the incorporation of soil amendments, the site should be inspected at least once after each storm event that exceeds 1/2 -inch of rainfall.

Compost Specifications The basic material specifications for compost amendments are outlined below: • Compost shall be derived from plant material and meet the general criteria set forth by the U.S. Composting Seal of Testing Assurance (STA) program. See vr�vw.com ostingcouncil.or for a list of local providers. • The compost shall be the result of the biological degradation and transformation of plant - derived materials under conditions that promote anaerobic decomposition. The material shall be well composted, free of viable weed seeds, and stable with regard to oxygen consumption and carbon dioxide generation. The compost shall have a moisture content that has no visible free water or dust produced when handling the material. It shall meet the following criteria, as reported by the U.S. Composting Council STA Compost Technical Data Sheet provided by the vendor: a. 100% of the material must pass through a half inch screen b. The pH of the material shall be between 6 and 8 c. Manufactured inert material (plastic, concrete, ceramics, metal, etc.) shall be less than 1.0% by weight d. The organic matter content shall be between 35% and 65% e. Soluble salt content shall be less than 6.0 mmhos/cm f. Maturity should be greater than 80% g. Stability shall be 7 or less Version 1.8, March 1, 2011 VAS DEQ STORMWATER DESIGN SPECIFICATION NO. 4 Page 5 of 10 SOIL COMPOST AMENDMENT Spot Reseeding. Inspectors should look for bare or eroding areas in the contributing drainage area or around the soil restoration area and make sure they are immediately stabilized with grass cover. Fertilization. Depending on the amended soils test, a one-time, spot fertilization may be needed in the .fall after the first growing season to increase plant vigor. Watering. Water once every three days for the first month, and then weekly during the first year (April -October), depending on rainfall. 9.3. Ongoing Maintenance There are no major on-going maintenance needs associated with soil compost amendments, although the owners may want to de -thatch the turf every few years to increase permeability. The owner should also be aware that there are maintenance tasks needed for filter strips, grass channels, and reforestation areas. An example maintenance inspection checklist for an area of Soil Compost Amendments can be accessed in Appendix C of Chapter 9 of the Virginia Stormwater Management Handbook (2010). SECTION 10.

REFER TO GOLF COURSE ARCHITECTURE PLANS FOR APPROPRIATE SEED MIX. SEQUENCE OF INSTALLATION PHASE I & II ARE PROPOSED WITHIN A SINGLE PLAN (SEE SHEETS 0501-0504) THE PROPOSED WORK WILL BE COMPLETED IN STAGES WITH EFFORTS FOCUSING ON DIFFERENT AREAS OF THE SITE AT A TIME. THE DIFFERENT STAGES OF WORK ARE SEPARATED BY SUB -AREAS, WHICH WILL BE DETERMINED AT THE TIME OF CONSTRUCTION AND COORDINATED WITH THE INSPECTOR AND ENGINEER. SUB -AREAS ARE DEFINED AS WORK AREAS ASSOCIATED WITH SPECIFIC E&S CONTROLS, SUCH AS DRAINAGE AREAS TO SEDIMENT TRAPS AND BASINS. THE E&S CONTROLS ASSOCIATED WITH EACH SUB -AREAS SHALL BE INSTALLED PRIOR TO STARTING WORK WITHIN THAT SUB -AREA. THIS STRADEGY IS INTENDED TO DELINEATE SMALLER AREAS OF WORK THAT CAN BEGIN PRIOR TO CONSTRUCTING ALL E&S CONTROLS FOR THE PROJECT. THE CONTROLS THAT ARE PROPOSED ADJACENT TO BODIES OF WATER (STREAMS, PONDS, WETLANDS) SHALL BE INSTALLED AS THE FIRST MEASURE OF WORK WITHIN A SUB -AREA. IN GENERAL, THE WORK SHOULD BE PERFORMED FROM THE MOST UPSTREAM PORTION OF EACH SUB -AREA, SUCH THAT THE UPSTREAM AREAS ARE CONSTRUCTED AND STABILIZED BEFORE MOVING DOWNSTREAM. FOR INSTANCE, AREAS FURTHER AWAY FROM THE PONDS SHOULD BE CONSTRUCTED BEFORE AREAS THAT ARE ADJACENT TO PONDS. THIS SEQUENCE WILL REDUCE SEDIMENT LADEN RUNOFF FROM CROSSING NEWLY CONSTRUCTED AREAS. ONSITE PONDS THE ONSITE PONDS ARE SUBJECT TO MAINTENANCE, WHICH IS INCLUDED IN THIS SCOPE OF WORK. WORK WITHIN THE DRAINAGE LIMITS SHOULD BE STABILIZED PRIOR TO DRAINING AND DREDGING PONDS (SCOPE OF WORK IS INDEPENDENT OF PROPOSED DEVELOPMENT, BUT IS IMMINENT). MITIGATION AREAS MITIGATION AREAS ARE PROPOSED WITHIN THE SITE, SPECIFICALLY NEAR STREAMS AND WITHIN NEW AND EXISTING STREAM BUFFER AREAS. THE STREAMS SHALL BE PROTECTED AS SHOWN IN THE E&S PLAN SHEETS AND INSTALLATION SHALL OCCUR AS THE FIRST MEASURE OF CONTROL FOR WORK WITHIN THE DRAINAGE AREA. WORK WITHIN MITIGATION AREAS SHOULD BE COMPLETED AFTER ANY UPSTREAM DEVELOPMENT HAS OCCURRED. MITIGATION WILL REQUIRE MECHANIZED EQUIPMENT TO REMOVE INVASIVE SPECIES AND CONSTRUCT VEGETATION IMPROVEMENTS - WORK WITHIN THESE AREAS IS LIMITED TO MITIGATION AND SIGNIFICANT EARTHWORK IS NOT PERMITTED. AFTER THE MITIGATION WORK HAS BEEN COMPLETED, THE MITIGATION (BUFFER AREA) SHOULD BE FLAGGED TO LIMIT FUTURE DISTURBANCE DURING CONSTRUCTION. WHEN THE MITIGATION AREAS HAVE BEEN STABILIZED THE E&S CONTROLS ADJACENT TO THE STREAMS SHOULD BE REMOVED. 1. INSTALL ALL EROSION AND SEDIMENT CONTROL MEASURES SHOWN ON THE PLAN (WITHIN THE SUB -AREA), STARTING WITH PERIMETER CONTROLS AND THE CONSTRUCTION ENTRANCE. 2. AFTER ALL OTHER EROSION AND SEDIMENT CONTROL PHASE MEASURES FOR A SUB -AREA ARE IN PLACE AND APPROVED BY THE E&S INSPECTOR, SITE WORK CAN BEGIN. 3. ROUGH GRADE PROJECT AREA. 4. SEED OR SOD ALL DENUDED AREAS PER VESCH STANDARDS. 5, FINE GRADE PROJECT AREA, APPLY PERMANENT SOIL STABILIZATION TO THESE AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS ACHIEVED. REFER TO MS -1 FOR TEMPORARY STABILIZATION REQUIREMENTS. 6. ALL STORMWATER PIPING & STRUCTURES SHALL BE INSPECTED FOR COUNTY GENERAL CONSTRUCTION NOTES FOR E&S CONTROL PLANS SILT/SEDIMENT. IF PRESENT, SILT/SEDIMENT SHALL BE CLEANED OUT FOR THE SYSTEM TO THE SATISFACTION OF THE E&S INSPECTOR. 7. ONCE THE DRAINAGE AREA TO THE SEDIMENT TRAP HAS BEEN STABILIZED AND APPROVED BY ESC INSPECTOR REMOVE SEDIMENT TRAP. 7.1. THE SEDIMENT TRAP IS LOCATED WITHIN AN AREA OF PROPOSED PARKING. THE UPSTREAM AREAS WILL NEED TO BE CONSTRUCTED AND STABILIZED PRIOR TO REMOVING THE SEDIMENT TRAP. 7.2. WHEN THE DENUDED DRAINAGE AREA TO THE BOX CULVERT IS LESS THAN 1 ACRE, THE SEDIMENT TRAP CAN BE REMOVED AND THE INLET PROTECTION AT THE BOX CULVERT GRATE WILL SERVE AS THE PRIMARY CONTROL DEVICE. 7.3. AS REQUIRED, ENSURE THE INLET PROTECTION AT THE BOX CULVERT IS MAINTAINED AND OPERATIONAL PRIOR TO REMOVAL OF THE SEDIMENT TRAP. 8. APPLY PERMANENT SOIL STABILIZATION TO THESE AREAS WITHIN SEVEN DAYS AFTER FINAL GRADE IS ACHIEVED. TREE PROTECTION, SILT FENCE, CULVERT INLET PROTECTION AND INLET PROTECTION BELOW SEDIMENT TRAPS MUST BE MAINTAINED THROUGH GRADING AND CONSTRUCTION. 9, ONCE CONSTRUCTION IS COMPLETE AND ALL CONTRIBUTING AREAS ARE STABILIZED, EROSION CONTROL MEASURES CAN BE REMOVED UPON APPROVAL FROM THE E&S INSPECTOR. 10. AT ALL TIMES, PROTECT THE NATURAL WATERWAYS FROM ANY SEDIMENT LADEN RUNOFF. TTEMPORARY BYPASS PIPES (VESCH TEMPORARY SLOPE DRAIN, OR EQUIVALENT) MAY BE REQUIRED TO DIVERT STORM DRAIN WATER AROUND SITE AREAS. SAFE WORK ENVIRONMENT CONTRACTOR SHALL PROVIDE A SAFE WORK ENVIRONMENT AT ALL TIMES. THE LIMITS OF WORK ARE LOCATED WITHIN AN ACTIVE GOLF COURSE AND RESORT FACILITY. CARE SHOULD BE GIVEN TO MONITORING SAFE PERIMETER CONDITIONS AND LIMITING ACCESS INTO WORK AREAS. MAINTENANCE OF TRAFFIC, INCLUDING CONSTRUCTION TRAFFIC, SHALL BE COORDINATED WITH UVA FOUNDATION.

Examples of recreational facilities that may be authorized by this NWP include playing fields (e.g., football fields baseball fields), basketballetball courts, tonnes courts,its hiking trails, bike paths, golf courses, ski areas, horse paths, nature centers, and campgrounds (excluding recreational vehicle parks). This NWP also authorizes the construction or expansion of small support facilities, such as maintenance and storage buildings and stables that are directly related to the recreational activity, but it does not authorize the construction of hotels, restaurants, racetracks, stadiums, arenas, or similar facilities. The discharge must not cause the loss of greater than 1/2 -acre of non -tidal waters of the United States, The discharge must not cause the loss of more than 300 linear feet of stream bed, unless for intermittent and ephemeral stream beds the district engineer waives the 300 linear foot limit by making a written determination concluding that the discharge will result in no more than minimal adverse environmental effects. The loss of stream bed plus any other losses of jurisdictional wetlands and waters caused by the NWP activity cannot exceed 1/2 -acre. This NWP does not authorize discharges into non -tidal wetlands adjacent to tidal waters. Notification: The permittee must submit a pre -construction notification to the district engineer prior to commencing the activity. (See general condition 32.)

NOTE: COUNTERSINKING S 39 40 41 42 3 5 6 NOT REQUIRED IN TIDAL WATERS. However, replacement pipes/culverts in tidal waters must be installed with invert elevations no higher than the existing pipe/culvert invert elevation, and a new pipe/culvert must be installed with the invert no higher than the stream bottom elevation. For Nontidal Waters: Following consultation with the Virginia Department of Game and Inland Fisheries (VDGIF), the Norfolk Districthas determined that fish and other aquatic organisms are most likely in any stream being crossed, in the absence of site-specific tic evidence to the contrary. Although prospective permittees have the option of providing such evidence, extensive efforts to collect such information is not encouraged, since countersinking will in most cases be required except as outlined in the conditions below. The following conditions will apply in nontidal waters: Iv I in streams will be countersunk at a. All pipes: All pipes and culverts aced PP PP P both the inlet and outlet ends, unless indicated otherwise by the Norfolk District on a case-by-case basis (see below). Pipes that are 24" or less in diameter shall be countersunk 3" below the natural stream bottom. Pipes that are greater than 24" in diameter shall be countersunk 6" below the natural stream bottom. The countersinking requirement does not apply to bottomless pipes/culverts or pipe arches. All single pipes or culverts (with bottoms) shall be depressed (countersunk) below the natural streambed at both the inlet and outlet of the structure. In sets of multiple pipes or culverts (with bottoms) at least one pipe or culvert shall be depressed (countersunk) at both the inlet and outlet to convey low flows. b. When countersinking culverts, permittees must ensure reestablishment of a surface water channel (within 15 days post construction) that allows for the movement of aquatic organisms and maintains the same hydrologic regime that was present pre -construction (i.e. the depth of surface water through the permit area should match the upstream and downstream depths). This may require the addition of finer materials to choke the larger stone and/or placement of riprap to allow for a low flow channel. C. Exemption for extensions and certain maintenance: The requirement to countersink does not apply to extensions of existing pipes or culverts that are not countersunk, or to maintenance to pipes/culverts tha t does not involve replacing the pipe/culvert (such as repairing cracks, adding material to prevent/correct scour, etc.). d, Floodplain pipes: The requirement to countersink does not apply to pipes or culverts that are being placed above ordinary high water, such as those placed to allow for floodplain flows. The placement of pipes above ordinary high water is not jurisdictional (provided no fill is discharged into wetlands). e. Hydraulic opening: Pipes should be adequately sized to allow for the passage of ordinary high water with the countersinking and invert restrictions taken into account. f, Pipes on bedrock or above existing utility lines: Different procedures will be followed for pipes or culverts to be placed on bedrock or above existing buried utility lines where it is not practicable to relocate the lines, depending on whether the work is for replacement of an existing pipe/culvert or a new pipe/culvert: 2 2. Aquatic Life Movements, No activity may substantially disrupt the necessary life cycle movements of those species of aquatic life indigenous to the waterbody, including those species that normally migrate throughh the area, unless the activity's s primary purpose e is to impoundound water.r, All permanent and temporary crossingss of waterbodies shall be suitably culverted, bridged, or otherwise designed and constructed to maintain low flows to sustain the movement of those aquatic species. If a bottomless culvert cannot be used, then the crossing should be designed and constructed to minimize adverse effects to aquatic life movements. 3. Spawning Areas. Activities in spawning areas during spawning seasons must be avoided to the maximum extent practicable. Activities that result in the physical destruction (e.g., through excavation, fill, or downstream smothering by substantial turbidity) of an important spawning area are not authorized. 4. Migratory Bird Breeding Areas. Activities in waters of the United States that serve as breeding areas for migratory birds must be avoided to the maximum extent practicable. 5. Shellfish Beds, No activity may occur in areas of concentrated shellfish populations, unless the activity is directly related to a shellfish harvesting activity authorized by NWPs 4 and 48, or is a shellfish seeding or habitat restoration activity authorized by N''„1P 27, 6. Suitabie Material. No activity may use unsuitable material (e.g., trash, debris, car bodies, asphalt, etc.). Material used for construction or discharged must be free from toxic pollutants in toxic amounts (see section 307 of the Clean Water Act). 7. Water Supply Intakes. No activity may occur in the proximity of a public water supply intake except where the activityis for the repair or improvement of public water supply intake structures or adjacent bank stabilization. 8. Adverse Effects from Impoundments. If the activity creates an impoundment of water, adverse effects to the aquatic system due to accelerating the passage of water, and/or restricting its flow must be minimized to the maximum extent practicable. 9. Management of Water Flows. To the maximum extent practicable, the pre - construction course, condition, capacity, and location of open waters must be maintained for each activity, including stream channelization, storm water management activities, and temporary and permanent road crossings, except as provided below. The activity must be constructed to withstand expected high flows. The activity must not restrict or impede the passage of normal or high flows, unless the primary purpose of the activity is to impound water or manage 9e hi h flows. The activity may alter the pre -construction course, condition, capacity, and location of open waters if it benefits the aquatic environment (e.g., stream restoration or relocation activities). 10. Fills Within 100 -Year Floodplains. The activity must comply with applicable FEMA - approved state or local floodplain management requirements - is not vCountersinking i etcul ert nexisting i- Re Replacement of a pP P required provided the elevations of the inlet and outlet ends of the replacement pipe/culvert are no higher above the stream bottom than those of the existing pipe/cul'vert. Documentation (photographic or other evidence) must be maintained in the permittee's records showing the bedrock condition and the existing et and outlet elevations. s'. That documentation will be inlet nest but notification or i riot upon req st available to the Norfolk D P coordination with the Norfolk District is not otherwise required, ii. A pipe/culvert is being placed in a new location: If the prospective permittee determines that bedrock or an existing buried utility line that is not practicable to relocate prevents countersinking, he/she should evaluate the use of a bottomless pipe/culvert, bottomless utility vault span an (g} brill e or other bottomless structure to cross the waterway, and also evaluate alternative locations for the new pipe/culvert that will allow for countersinking. If the prospective permittee determines that neither a bottomless structure nor an alternative location is practicable, then he/she must submit a pre - construction notification (PCN) to the Norfolk District in accordance with General Condition 32 of the NWPs. In addition to the information required by General Condition 32, the prospective permittee must provide documentation of measures evaluated to minimize disruption of the movement of aquatic life as well as documentation of the dost, engineering factors, and site conditions that prohibit countersiniking the pipe/culvert. Options that must be considered include partial countersinking (such as less than 3" of countersinking, or icountersinking of one end of the pipe), and constructing stone step pools, low rock weirs downstream, or other measures t€o provide for the movement of aquatic organisms. The PCN must also include photographs documenting site conditions. The prospective permittee may find it helpful to contact the regional fishery biologist for the VDGIF, for recommendations about the measures to be taken to allow for fish movements. When seeking advice from VDGIF, the prospective permittee should provide the VDGIF biologist with all available information such as location, flow rates, stream bottom features, description of proposed pipe(s), slopes, etc. Any recommendations from VDGIF should be included in the PCN. r The Norfolk District will notify the prospective permittee whether the proposed work qualifies for the nationwide permit within 45 days of receipt of a complete PCN. NOTE: Blasting of stream bottoms through the use of explosives is not acceptable as a means of providing for countersinking of pipes on bedrock. g. Pipes on steep terrain: Pipes being placed on steep terrain (slope of 5% or greater) must be countersunk in accordance with the conditions above and will in most cases be non -reporting. It is recommended that on slopes greater than 5%, a larger pipe than required be installed to allow for the passage of ordinary high water in order to increase the likelihood that natural velocities can be maintained. There may be situations where countersinking both the inlet and outlet may result in a slope in the pipe 11. Equipment. Heavy equipment working in wetlands or mudflats must be placed on mats, or other measures must be taken to minimize soil disturbance. 12. So! Erosion osian and Sediment Controls. Appropriate soil erosion and sediment controls must be use and maintained in effective operating condition during construction, and all exposed soil and other fills, as well as any work below the ordinary high water mark or high tide fine, must be permanently stabilized at the earliest practicable date. Permittees are encouraged to perform work within waters of the United States during periods of low -flow or no -flow, or during low tides. 13. Removal of Temporary Fills. Temporary fills must be removed in their entirety and the affected areas returned to pre -construction elevations. The affected areas must be revegetated, as appropriate, 14, Proper Maintenance. Any authorized structure or fill shall be properly maintained, including maintenance to ensure public safety and compliance with applicable NWP general conditions, as well as any activity -specific conditions added by the district engineer to an NWP authorization. 15. Single and Complete Project. The activity must be a single and complete project, The same NWP cannot be used more than once for the same single and complete project. 16. Wild and Scenic Rivers. (a) No NWP activity may occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a "study river" for possible inclusion in the system while the river is in an official study status, unless the appropriate Federal agency with direct management responsibility for such river, has determined in writing that the proposed activity will not adversely affect the Wild and Scenic River designation or study status. 9 Y (b) If a proposed NWP activity will occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a "study river" for possible inclusion in the system while the river is in an official study status, the permittee must submit a pre -construction notification (see general condition 32). The district engineer will coordinate the PCN with the Federal agency with direct management responsibility for that river. The permittee shall not begin the NWP activity until notified by the district engineer that the Federal agency with direct management responsibility for that river has determined in writing that the proposed NWP activity will not adversely affect the Wild and Scenic River designation or study status, (c) information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency responsible for the designated Wild and Scenic River or study river (e.g., Natina I Park Service U S .Forest Service Bureau of Land Management, U.S. Fish and Wildlife Service). Information on these rivers is also htt ; /www.rivers. available at ov/. p / g 17, Tribal Rights. No NWP activity may cause more than minimal adverse effects on tribal rights (including treaty rights), protected tribal resources, or tribal lands. 18. Endangered Species. 3 on that results in flow velocities that cause excessive scour at the outlet and/or prohibit some fish movement. This type of situation could occur on the side of a mountain where falls and drop pools occur along a stream. Should this be the case, or should the prospective permittee not want to countersink the pipe/culvert for other reasons, he/she must submit a PCN to the Norfolk District in accordance with General Condition 32 of the Nationwide Permits. In additionn to the information required by General Condition 32 the prospective permittee must provide e documentation of aquatic movement of e a measures evaluated to minimize disruption of the q life as well as documentation of the cost, engineering factors, and site conditions that prohibit countersinking the pipe/culvert. The prospective permittee should design the pipe to be placed at a slope as steep as stream characteristics allow, countersink the inlet 3-6", and implement measures to minimize any disruption of fish movement, These measures can include constructing a stone step/pool structure, preferably using river rock/native stone rather than riprap, constructing low rock weirs to create a pool or pools, or other structures to allow for fish movements in both directions. Stone structures should be designed with sufficient -sized stone to prevent erosion or washout and should include keying -in as appropriate. These structures should be designed both to allow for fish passage and to minimize scour at the outlet. The quantities of fill discharged below ordinary high water necessary to comply with these requirements (i.e., the cubic yards of stone, riprap or other fill placed e below the plane of ordinary high water) must be included in project totals. The prospective permittee may find it helpful to contact the regional fishery biologist for the VDGIF for recommendations about the measures to be taken to allow for fish movements. When seeking advice from DGIF, the prospective permittee should provide the DGIF biologist with all available information such as location, flow rates, stream bottom features, description of proposed pipe(s), slopes, etc. Any recommendations from DGIF should be included in the PCN. The Norfolk District will notify the prospective permittee whether the proposed work qualifies for the nationwide permit within 45 days of receipt of a complete PCN, h, Problems encountered during construction: When a pipe/culvert is being replaced, and the design calls for countersinking at both ends of the pipe/culvert, and during construction it is found that the streambed/banks are on bedrock, a utility line, or other documentable obstacle, then the permittee must stop work and contact the Norfolk District (contact by telephone and/or email is acceptable). The permittee must provide the Norfolk District with specific information concerning site conditions and limitations on countersinking. The Norfolk District will work with the permittee to determine an acceptable plan, taking into consideration the information provided by the permittee, but the permittee should recognize that the Norfolk District could determine that the work will not qualify for a nationwide permit. L Emergency pipe replacements: In the case of an emergency situation, such as when a pipe/culvert washes out during a flood, a permittee is encouraged to countersink the replacement pipe at the time of replacement, in accordance with the conditions above. However, if conditions or timeframes do not allow for countersinking, then the pipe (a) No activity is authorized under any NWP which is likely to directly or indirectly jeopardize the continued existence of a threatened or endangered species or a species proposed for such designation, as identified under the Federal Endangered Species Act (ESA), or whish wilt directly or indirectly destroy or adversely modify the critical habitat of such species. s. No activity is authorized under any NWP which "may affect" a listed species or critical habitat, unless ESA section 7 consultation addressing the effects of the proposed activity has been completed. Direct effects are the immediate effects on listed species and critical habitat caused by the NWP activity. Indirect effects are those effects on listed species and critical habitat that are caused by the NWP activity and are later in time, but still are reasonably certain to occur. (b) Federal agencies should follow their own procedures for complying with the requirements of the ESA. If pre -construction notification is required for the proposed activity, the Federal permittee must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. The district engineer will verify that the appropriate documentation has been submitted. If the appropriate documentation has not been submitted, additional ESA section 7 consultation may be necessary for the activity and the respective federal agency would be responsible for fulfilling its obligation under section 7 of the ESA. (c) Non-federal permittees must submit a pre -construction notification to the district engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the activity, or if the activity is located in designated critical habitat, and shall not begin work on the activity until notified by the district engineer that the requirements of the ESA have been satisfied and that the activity is authorized- For activities that might affect Federally -listed endangered or threatened species or designated critical habitat, the pre -construction notification must include the name(s) of the endangered or threatened species that might be affected by the proposed activity or that utilize the designated critical habitat that might be affected by the proposed activity. The district engineer will determine whether the proposed activity "may affect" or will have "no effect" to listed species and designated critical habitat and will notify the non -Federal applicant of the Corps' determination within 45 days of receipt of a complete pre -construction notification, In cases where the non -Federal applicant has identified listed species or critical habitat that might be affected or is in a the vicinity of the activity, and has so notified the Corps, theapplicant shall not begin work until the Corps has provided notification that the proposed activity will have "no effect" on listed species or critical habitat, oruntil ESA section 7 consultation has been completed. If the non -Federal applicant has not heard back from the Corps within 45 days, the applicant must still wait for notification from the Corps. (d) As a result of formal or informal consultation with the FWS or NMFS the district engineer may add species-specific permit conditions to the NWPs. (e) Authorization of an activity by an NWP does not authorize the "take" of a threatened or endangered species as defined under the ESA. In the absence of separate authorization (e.g., an ESA Section 10 Permit, a Biological Opinion with "incidental take" provisions, etc.) from the FWS or the NMFS, the Endangered Species Act prohibits any person subject to the jurisdiction of the United States to take a listed species, where "take" means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct. The word "harm" in the definition of "take" means an act which actually kills or injures wildlife. Such an act may include significant habitat modification or degradation where it actually kills or injures wildlife by significantly impairing essential behavioralpatterns including breeding, feeding or sheltering, M E DESIGNED BY J, WILSON CHECKED BY ® o C, KOTARSKI 0 SCALE 0 M V N vi N tZ > E w E LU i� U L_ w � 3.

Q o 1.0 �-i 0 N I- - m (f]i If the non-federal permittee has a valid ESA section 1 0(a)(1)(B) incidental take permit with an approved Habitat Conservation Plan for a project or a group of projects that includes the proposed NWP activity, the non-federal applicant should provide a copy of that ESA section 10(a)(1)(B) permit with the PCN required by paragraph (c) of this general condition. The district engineer will coordinate with the agency that issued the ESA section 1 0(a)(1)(B) permit to determine whether the proposed NWP activity and the associated incidental take were co nsidered in the internal ESA section 7 consultation conducted for the ESA section 10(a)(1)(B) permit. If that coordination results in concurrence from the agency that the proposed NWP activity and the associated incidental take were considered in the internal ESA section 7 consultation for the ESA section I 0(a)(1)(B) permit, the district engineer does not need to conduct a separate ESA section 7 consultation for the proposed NWP activity. The district engineer will notify the non-federal applicant within 45 days of receipt of a complete pre -construction notification whether the ESA section 1 0(a)(1)(B) permit covers the proposed NWP activity or whether additional ESA section 7 consultation is required. (g) Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the FWS and NMFS or their World Wide Web pages at http://www.fws,gov/ or http://www,fws.gov/ipac and http://www.nmfs.noaa.gov/pr/species/esa/ respectively. 19. Migratory Birds and Bald and Golden Eagle . The permittee is responsible for ensuring their action complies with the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The permittee is responsible for contacting appropriate local office of the U.S. Fish and Wildlife Service to determine applicable measures to reduce impacts to migratory birds or eagles, including whether "incidental take" permits are necessary and available under the Migratory Bird Treaty Act or Bald and Golden Eagle Protection Act for a particular activity. 20. Historic Properties. (a) In cases where the district engineer determines that the activity may have the potential to cause effects to properties listed, or eligible for listing, in the National Register of Historic Places, the activity is not authorized, until the requirements of Section 106 of the National Historic Preservation Act (NHPA) have been satisfied. (b) Federal permittees should follow their own procedures for complying with the requirements of section 106 of the National Historic Preservation Act. If pre - construction notification is required for the proposed NWP activity, the Federal permittee must provide the district engineer with the appropriate documentation to dernonstrate compliance with those requirements. The district engineer will verify that the appropriate documentation has been submitted. If the appropriate documentation is not submitted, then additional consultation under section 106 may be necessary. The respective federal agency is responsible for fulfilling its obligation to comply with section 106. (c) Non-federal permittees must submit a pre -construction notification to the district engineer if the NWP activity might have the potential to cause effects to any historic properties listed on, determined to be eligible for listing on, or potentially eligible for listing on the National Register of Historic Places, including previously unidentified properties. For such activities, the pre -construction notification must state which historic properties might have the potential to be affected by the proposed NWP activity or include a vicinity map indicating the location of the historic properties or the potential for the presence of historic properties. Assistance regarding information on (c) The signature of the permittee certifying the completion of the activity and mitigation. The completed certification document must be submitted to the district engineer within 30 days of completion of the authorized activity or the implementation of any required compensatory mitigation, whichever occurs later. 31. Activities Affecting Structures or Works Built by the United States. If an NWP activity also requires permission from the Corps pursuant to 33 U.S.C. 408 because it will alter or temporarily or permanently occupy or use a U.S. Army Corps of Engineers (USACE) federally authorized Civil Works project (a "USACE project"), the prospective permittee must submit a pre -construction notification. See paragraph (b)(11 0) of general condition 32. An activity that requires section 408 permission is not authorized by NWP until the appropriate Corps office issues the section 408 permission to alter, occupy, or use the USACE project, and the district engineer issues a written NWP verification. 32. Pre -Construction Notification. (a) Timing, Where required by the terms of the NWP, the prospective permittee . must notify the district engineer by submitting a pre -construction notification (PCN) as early as possible. The district engineer must determine if the PCN is complete within 30 calendar days of the date of receipt and, if the PCN is determined to be incomplete, notify the prospective permittee within that 30 day period to request the additional information necessary to make the PCN complete. The request must specify the information needed to make the PCN complete. As a general rule, district engineers will request additional information necessary to make the PCN complete only once. However, if the prospective permittee does not provide all of the requested information, then the district engineer will notify the prospective permittee that the PCN is still incomplete and the PCN review process will not commence until all of the requested information has been received by the district engineer. The prospective permittee shall not begin the activity until either: that the activity may (1) He or she is notified in writing by the district engineer osed by the district or proceed under the NWP with any special conditions imp division engineer; or (2) 45 calendar days have passed from the district engineer's receipt of the complete PCN and the prospective permittee has not received written notice ired to from the district or division engineer. However, if the permittee was requ notify the Corps pursuant to general condition 18 that listed species or critical habitat might be affected or are in the vicinity of the activity, or to notify the Corps pursuant to general condition 20 that the activity might have the potential to cause effects to historic properties, the permittee cannot begin the activity until receiving written notification from the Corps that there is "no effect" on listed species or "no potential to cause effects" on historic properties, or that any consultation required under Section 7 of the Endangered Species Act (see 33 CFR 330.4(f)) and/or section 106 of the National Historic Preservation Act (see 33 CFR 330.4(g)) has been completed. Also, work cannot begin under NWPs 21, 49, or 50 until the permittee has received written approval from the Corps. If the proposed activity requires a written waiver to exceed specified limits of an NWP, the permittee may not begin the activity until the district engineer issues the waiver. If the district or division engineer notifies the permittee in writing that an individual permit is required 7 10 the location of, or potential for, the presence of historic properties can be sought from the State Historic Preservation Officer, Tribal Historic Preservation Officer, or designated tribal representative, as appropriate, and the National Register of Historic Places (see 33 CFR 330.4(g)). When reviewing pre -construction notifications, district engineers will comply with the current procedures for addressing the requirements of section 106 of the National Historic Preservation Act. The district engineer shall make a reasonable and good faith effort to carry out appropriate identification efforts, which may include background research, consultation, oral history interviews, sample field investigation, and field survey, Based on the information submitted in the PCN and these identification efforts, the district engineer shall determine whether the proposed NWP activity has the potential to cause effects on the historic properties. Section 106 consultation is not required when the district engineer determines that the activity does not have the potential to cause effects on historic properties (see 36 CFR 800.3(a)). Section 106 consultation is required when the district engineer determines that the activity has the potential to cause effects on historic properties. The district engineer will conduct consultation with consulting parties identified under 36 CFR 800.2(c) when he or she makes any, of the following effect determinations for the purposes of section 106 of the NHPA: no historic properties affected, no adverse effect, or adverse effect. Where the non-Fedieral applicant has identified historic properties on which the activity might have the potential to cause effects and so notified the Corps, the non - Federal applicant shall not begin the activity until notified by the district engineer either that the activity has no potential to cause effects to historic properties or that NHPA section 106 consultation has been completed. (d) For non-federal permittees, the district engineer will notify the prospective permittee within 45 days of' receipt of a complete pre -construction notification whether NHPA section 106 consultation is required. If NHPA section 106 consultation is required, the district engineer will notify the non -Federal applicant that he or she cannot begin the activity until section 106 consultation is completed. If the non -Federal applicant has not heard back from the Corps within 45 days, the applicant must still wait for notification from the Corps, (e) Prospective permittees should be aware that section I 1 Ok of the N HPA (54 U�S.C. 3061 13) prevents the Corps from granting a permit or other assistance to an applicant who, with intent tc) avoid the requirements of section 106 of the NHPA, has intentionally significantly adversely affected a historic property to which the permit would relate, or having legal power to prevent it, allowed such significant adverse effect to occur, unless the Corps, after consultation with the Advisory Council on Historic Preservation (ACHIP), determines that circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If circumstances justify grantiing the assistance, the Corps is required to notify the ACHP and provide documentation specifying the circumstances, the degree of damage to the integrity of any historic properties affected, and proposed mitigation. This documentation must include any views obtained from the applicant, SHPO/THPO, appropriate Indian tribes if the undertaking occurs on or affects historic properties on tribal lands or affects properties of interest to those tribes, and other parties known to have a legitimate interest in the impacts to the permitted activity on historic properties. 21. Discovery of Previously Unknown Remains and Artifacts. If you discover any previously unknown historic, cultural or archeological remains and artifacts while accomplishing the activity authorized by this permit, you must immediately notify the district engineer of what yoiu have found, and to the maximum extent practicable, within 45 calendar (days of receipt of a complete PCN, the permittee cannot begin the activity until an individual permit has been obtained. Subsequently, the permittee's righit to proceed under the NWP may be modified, suspended, or revoked only in accordance with the procedure set forth in 33 CFR 330.5(d)(2)� (b) Contents of Pre -Construction Notification: The PCN must be in writing and include the following in1formation: (1) Name, address and telephone numbers of the prospective permittee; (2) Location of the 1proposed activity, (3) Identify the spe(cific NWP or NWP(s) the prospective permittee wants to use to authorize the proposed activity; (4) A description of' the proposed activity; the activity's purpose; direct and indirect adverse enivironmental effects the activity would cause, including the anticipated amount of loss of wetlands, other special aquatic sites, and other waters expected ioi result from the NWP activity, in acres, linear feet, or other appropriate unit of measure; a description of any proposed mitigation measures intended to reduce the adverse environmental effects caused by the proposed activity; and any other NWP(s), regional general permit(s), or individual permit(,,;) used or intended to be used to authorize any part of the proposed project or any related activity, including other separate and distant crossings for linear projects that require Department of the Army authorization but do not require pre -construction notification. The description of the proposed activity and any proposed mitigation measures should be sufficiently detailed to allow the district engineer to determine that the adverse environmental effects of the activity will be no more than minimal and to determine the need for compensatory mitigation or other mitigation measures. For single and canplete linear projects, the PCN must include the quantity of anticipated losses *f wetlands, other special aquatic sites, and other waters for each single and complete crossing of those wetlands, other special aquatic sites, and other "aiters. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP. (Sketches usually clarify the activity and when provided results in a quicker decision. Sketches should contain sufficient detail to provide an illustrative description of the proposed activity (e.g., a conceptual plan), but do not need to be detailed engineering plans); (5) The PCN must include a delineation of wetlands, other special aquatic sites, and other waters, such as lakes and ponds, and perennial, intermittent, and ephemeral streams, on the project site. Wetland delineations must be prepared in accordance with the current method required by the Corps. The permittee may ask the Corps to delineate the special aquatic sites and other waters on the project site, but there may be a delay if the Corps does the delineation, espedally if the project site is large or contains many wetlands, other special aquatic sites, and other waters. Furthermore, the 45 day period will not start until the delineation has been submitted to or completed by the Corps, as appropriate - 1 (6) If the proposed activity will result in the loss of greater than I /1 0 -acre of wetlands and a PCN is required, the prospective permittee must submit a statement describing how the mitigation requirement will be satisfied, or explaining why the adverse environmental effects are no more than minimal avoid construction activities that may affect the remains and artifacts until the required coordination has been completed. The district engineer will initiate the Federal, Tribal, and state coordination required to determine if the items or remains warrant a recovery effort or if the site is eligible for listing in the National Register of Historic Places. 22. Designated Critical Resource Waters. Critical resource waters include, NOAA- ine sanctuaries and marine monuments, and National Estuarine Research Reserves. The district engineer may designate, after notice and opportunity for public comment, additional waters officially designated by a state as having particular environmental or ecological significance, such as outstanding national resource waters or state natural heritage sites. The district engineer may also designate additional critical resource waters after notice and opportunity for public comment. (a) Discharges of dredged or fill material into waters of the United States are not authorized by NWPs 7, 12, 14, 16, 17, 21, 29, 31, 35, 39, 40, 42, 43, 44, 49, 50, 5 1, and 52 for any activity within, or directly affecting, critical resource waters, including wetlands adjacent to such waters. (b) For NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, 38, and 54, notification is required in accordance with general condition 32, for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The district engineer may authorize activities under these NWPs only after it is determined that the impacts to the critical resource waters will be no more than minimal. 23. Mitigation. The district engineer will consider the following factors when determining appropriate and practicable mitigation necessary to ensure that the individual and cumulative adverse environmental effects are no more than minimal: (a) The activity must be designed and constructed to avoid and minimize adverse effects, both temporary and permanent, to waters of the United States to the maximum extent practicable at the project site (i.e,, on site). (b) Mitigation in all its forms (avoiding, minimizing, rectifying, reducing, or uired to the extent necessary to ensure compensating for resource losses) will be req that the individual and cumulative adverse environmental effects are no more than minimal. (c) Compensatory mitigation at a minimum one-for-one ratio will be required for all wetland losses that exceed 1/10 -acre and require pre -construction notification, unless the district engineer determines in writing that either some other form of mitigation would be more environmentally appropriate or the adverse environmental effects of the proposed activity are no more than minimal, and provides an activity -specific waiver of this requirement, For wetland losses of 1 /1 0 -acre or less that require pre - construction notification, the district engineer may determine on a case-by-case basis that compensatory mitigation is required to ensure that the activity results in only minimal adverse environmental effects. (d) For losses of streams or other open waters that require pre -construction notification, the district engineer may require compensatory mitigation to ensure that the activity results in no more than minimal adverse environmental effects. Compensatory mitigation for losses of streams should be provided, if practicable, through stream rehabilitation, enhancement, or preservation, since streams are d ifficu It -to -rep lace resources (see 33 CFR 332-3(e)(3)). and why compensatory mitigation should not be required. As an alternative, the prospective permittee may submit a conceptual or detailed mitigation plan. (7) For non -Federal permittees, if any listed species or designated critical habitat might be affected or is in the vicinity of the activity, or if the activity is located in designated critical habitat, the PCN must include the name(s) of those endangered or threatened species that might be affected by the proposed activity or utilize the designated critical habitat that might be affected by the proposed activity. For NWP activities that require pre -construction notification, Federal permittees must provide documentation demonstrating compliance with the Endangered Species Act; (8) For non -Federal permittees, if the NWP activity might have the potential to cause effects to a historic property listed on, determined to be eligible for listing on, or potentially eligible for listing on, the National Register of Historic Places, the PCN must state which historic property might have the potential to be affected by the proposed activity or include a vicinity map indicating the location of the historic property. For NWP activities that require pre - construction notification, Federal permittees must provide documentation demonstrating compliance with section 106 of the National Historic Preservation Act; (9) For an activity that will occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a "study river" for possible inclusion in the system while the river is in an official study status, the PCN must identify the Wild and Scenic River or the "study river' (see general condition 16); and (1 0) For an activity that requires permission from the Corps pursuant to 33 U.S.C. 408 because it will alter or temporarily or permanently occupy or use a U.S. Army Corps of Engineers federally authorized civil works project, the pre - construction notification must include a statement confirming that the project proponent has submitted a written request for section 408 permission from the Corps office having jurisdiction over that USACE project. (c) Form of Pre -Construction Notification: The standard individual permit application form (Form ENG 4345) may be used, but the completed application form must clearly indicate that it is an NWP PCIN and must include all of the applicable information required in paragraphs (b)(1) through (10) of this general condition. A letter containing the required information may also be used. Applicants may provide electronic files of PCNs and supporting materials if the district engineer has established tools and procedures for electronic submittals. (d) Agency Coordination: . (1) The district engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the terms and conditions of the NWPs and the need for mitigation to reduce the activity's adverse environmental effects so that they are no more than minimal. (2) Agency coordination is required for: (i) all NWP activities that require pre - construction notification and result in the loss of greater than 1/2 -acre of waters of the United States; (ii) NWP 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52 activities that require pre -construction notification and will result in the loss of greater than 300 linear feet of stream bed; (iii) NWP 13 activities in excess of 500 linear feet, fills greater than one cubic yard per running foot, or involve discharges of dredged or fill material into special aquatic sites; and (iv) NWP 54 activities in excess of 500 linear feet, or that extend into the waterbody I 1 M (e) Compensatory mitigation plans for NWP activities in or near streams or other open waters will normally include a requirement for the restoration or enhancement, maintenance, and legal protection (e.g., conservation easements) of riparian areas next to open waters. In some cases, the restoration or maintenance/protection of riparian areas may be the only compensatory mitigation required. Restored riparian areas should consist of native species. The width of the required riparian area will address documented water quality or aquatic habitat loss concerns. Normally, the riparian area will be 25 to 50 feet wide on each side of the stream, but the district engineer may require slightly wider riparian areas to address documented water quality or habitat loss concerns, If it is not possible to restore or maintain/protect a � . riparian area on both sides of a stream, or if the waterbody is a lake or coastal waters, then restoring or maintaining/protecting a riparian area along a single bank or shoreline may be sufficient. Where both wetlands and open waters exist on the project s I ite, � the district engineer will determine the appropriate compensatory mitigation (e.g., riparian areas and/or wetlands compensation) based on what is best for the aquatic environment on a watershed basis. In cases where riparian areas are determined to be the most appropriate form of minimization or compensatory mitigation, the district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland losses. (f) Compensatory mitigation projects provided to offset losses of aquatic resources must comply with the applicable provisions of 33 CFR part 332. (1) The prospective permittee is responsible for proposing an appropriate compensatory mitigation option if compensatory mitigation is necessary to ensure that the activity results in no more than minimal adverse environmental effects. For the NWPs, the preferred mechanism for providing compensatory mitigation is mitigation bank credits or in -lieu fee program credits (see 33 CFR 332.3(b)(2) and (3)). However, if an appropriate number and type of mitigation bank or in -lieu credits are not available at the time the PCN is submitted to the district engineer, the district engineer may approve the use of permittee -responsible mitigation. (2) The amount of compensatory mitigation required by the district engineer must be sufficient to ensure that the authorized activity results in no more than minimal individual and cumulative adverse environmental effects (see 33 CFR 330.1(e)(3)). (See also 33 CFR 332.3(f)). (3) Since the likelihood of success is greater and the impacts to potentially valuable uplands are reduced, aquatic resource restoration should be the first compensatory mitigation option considered for permittee -responsible mitigation. (4) If permittee -responsible mitigation is the proposed option, the prospective permittee is responsible for submitting a mitigation plan. A conceptual or detailed mitigation plan may be used by the district engineer to make the decision on the NWP verification request, but a final mitigation plan that addresses the applicable requirements of 33 CFR 332.4(c)(2) through (14) must be approved by the district engineer before the permittee begins work in waters of the United States, unless the district engineer determines that prior approval of the final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation (see 33 CFR 332.3(k)(3)). (5) If mitigation bank or in -lieu fee program credits are the proposed option, the mitigation plan only needs to address the baseline conditions at the impact site and the number of credits to be provided. (6) Compensatory mitigation requirements (e.g., resource type and amount to be provided as compensatory mitigation, site protection, ecological performance more than 30 feet from the mean low water line in tidal waters or the ordinary high water mark in the Great Lakes. (3) When agency coordination is required, the district engineer will immediately provide (e.g., via e-mail, facsimile transmission, overnight mail, or other expeditious manner) a copy of the complete PCN to the appropriate Federal or state offices (FWS, state natural resource or water quality agency, EPA, and, if appropriate, the NMFS). With the exception of NWP 37, these agencies will have 10 calendar days from the date the material is transmitted to notify the district engineer via telephone, facsimile transmission, or e-mail that they intend to provide substantive, site-specific comments, The comments must explain why the agency believes the adverse environmental effects will be more than minimal. If so contacted by an agency, the district engineer will wait an additional 15 calendar days before making a decision on the pre - construction notification. The district engineer will fully consider agency cornments received within the specified time frame concerning the proposed activity's compliance with the terms and conditions of the NWPs, including the need for mitigation to ensure the net adverse environmental effects of the proposed activity are no more than minimal. The district engineer will provide no response to the resource agency, except as provided below. The district engineer will indicate in the administrative record associated with each pre - construction notification that the resource agencies' concerns were considered. For NWP 37, the emergency watershed protection and rehabilitation activity may proceed immediately in cases where there is an unacceptable hazard to life or a significant loss of property or economic hardship will occur. The district engineer will consider any comments received to decide whether the NWP 37 authorization should be modified, suspended, or revoked in accordance with the procedures at 33 CFR 330.5. (4) In cases of where the prospective permittee is not a Federal agency, the district engineer will provide a response to NMFS within 30 calendar days of receipt of any Essential Fish Habitat conservation recommendations, as required by section 305(b)(4)(B) of the Magnuson -Stevens Fishery Conservation and Management Act. (5) Applicants are encouraged to provide the Corps with either electronic files or multiple copies of pre -construction notifications to expedite agency coordination. DISTRICT ENGINEER'S DECISION: I . In reviewing the PCN for the proposed activity, the district engineer will determine whether the activity authorized by the NWP will result in more than minimal individual or cumulative adverse environmental effects or may be contrary to the public interest, If a project proponent requests authorization by a specific NWP, the district engineer should issue the NWP verification for that activity if it meets the terms and conditions of that NWP, unless he or she determines, after considering mitigation, that the proposed activity will result in more than minimal individual and cumulative adverse effects on the aquatic environment and other aspects of the public interest and exercises discretionary authority to require an individual permit for the proposed activity. For a linear project, this determination will include an evaluation of the individual crossings of waters of the United States to determine whether they conditions of the NWP(s), as well as the cumulative individually satisfy the terms and standards, monitoring requirements) may be addressed through conditions added to the NWP authorization, instead of components of a c:ompensatory mitigation plan (see 33 CFR 332A(c)(`!)(ii))� (g) Compensatory mitigation will not be used to increase the acreage losses allowed by the acreage limits of the NWPs. For example, if an NWP has an acreage limit of 1/2 -acre, it cannot be used to authorize any NWP activity resulting in the loss of greater than 1/2 -acre of waters of the United States, even if compensatory mitigation is provided that replaces or restores some of the lost waters. However, compensatory mitigation can and should be used, as necessary, to ensure that an NWP activity already meeting the established acreage limits also satisfies the no more than minimal impact requirement for the NWPs. (h) Permittees may propose the use of mitigation banks, in -lieu fee programs, or permittee -responsible mitigation. When developing a compensatory mitigation proposal, the permittee must consider appropriate and practicable options consistent with the framework at 33 CFR 332.3(b). For activities resulting in the loss of marine or estuarine resources, permittee -responsible mitigation may be environmentally preferable if there are no mitigation banks or in -lieu fee programs in the area that have marine or estuarine credits available for sale or transfer to the permittee. For permittee -responsible mitigation, the special conditions of the NWP verification must clearly indicate the party or parties responsible for the implementation and performance of the compensatory mitigation project, and, if required, its long-term management. (i) Where certain functions and services of waters of the United States are permanently adversely affected by a regulated activity, such as discharges of dredged or fill material into waters of the United States that will convert a forested or scrub - shrub wetland to a herbaceous wetland in a permanently maintained utility line right- of-way, mitigation may be required to reduce the adverse environmental effects of the activity to the no more than minimal level. 24. Safety of Impoundment Structures. To ensure that all impoundment structures are safely designed, the district engineer may require non -Federal applicants to demonstrate that the structures comply with established state dam safety criteria or have been designed by qualified persons. The district engineer may also require documentation that the design has been independently reviewed by similarly qualified persons, and appropriate modifications made to ensure safety. 25. Water Quality, Where States and authorized Tribes, or EPA where applicable, have not previously certified compliance of an NWP with CWA section 401, individual 401 Water Quality Certification must be obtained or waived (see 33 CFR 330.4(c)). The district engineer or State or Tribe may require additional water quality management measures to ensure that the authorized activity does not result in more than minimal degradation of water quality. 26. Coastal Zone Management. In coastal states where an NWP has not previously received a state coastal zone management consistency concurrence, an individual state coastal zone management consistency concurrence must be obtained, or a presumption of concurrence must occur (see 33 CFR 330.4(d)). The district engineer or a State may require additional measures to ensure that the authorized activity is consistent with state coastal zone management requirements. effects caused by all of the crossings authorized by NWP. If an applicant requests a waiver of the 300 linear foot limit on impacts to streams ior of an otherwise applicable limit, as provided for in NWPs 13, 21, 29, 36, 39, 40, 42, 43, 44, 50, 51, 52, or 54, the district engineer will only grant the waiver upon a written determination that the NWP activity will result in only minimal individual and cumulative adverse environmental effects. For those NWPs that have a waivable 300 linear foot limit for losses of intermittent and ephemeral stream bed and a 1/2 -acre limit (i.e., NWPs 21, 29, 39, 40, 42, 43, 44, 50, 51, and 52), the loss of intermittent and ephemeral stream bed, pLis any other losses of jurisdictional waters and wetlands, cannot exceed 1/2 -acre. 2, When making minimal adverse environmental effects determinations the district engineer will consider the direct and indirect effects caused by the NWP activity. He or she will also consider the cumulative adverse environmental effects caused by activities authorized by NWP and whether those cumulative adverse environmentall effects are no more than minimal. The district engineer will also consider site specific factors, such as the environmental setting in the vicinity of the NWP activity, the type of resource that will be affected by the NWP activity, the functions provided by the aquatic resources that will be affected by the NWP activity, the degree or magnitude to which the aquatic resources perform those functions, the extent that aquatic resource functions will be lost as a result of the NWP activity (e.g., partial or complete loss), the duration of the adverse effects (temporary or permanent), the importance of the aquatic resource functions to the region (e.g., watershed or ecoregion), and mitigation required by the district engineer. If an appropriate functional or condition assessment method is available and practicable to use, that assessment method may be used by the district engineer to assist in the minimal adverse environmental effects determination. The district engineer may add case-speciific special conditions to the NWP authorization to address site-specific environmental concerns. 3. If the proposed activity requires a PCN and will result in a loss of greater than 1 /1 0 - acre of wetlands, the prospective permittee should submit a mitigation proposal with the PCN. Applicants may also propose compensatory mitigation for NWP activities with smaller impacts, or for impacts to other types of waters (e.g., streams). ThE district engineer will consider any proposed compensatory mitigation or other mitigation measures the applicant has included in the proposal in determining whether the net adverse environmental effects of the proposed activity are no more than minimal. The compensatory mitigation proposal may be either conceptual or detailed. If the district engineer determines that the activity complies with the terms and conditions of the NWP and that the adverse environmental effects are no more than minimal, after considering mitigation, the district engineer will notify the permittee and include any activity -specific conditions in the NWP verification the district engineer deems necessary. Conditions for compensatory mitigatiion requirements must comply with the appropriate provisions at 33 CFR 332.3(k). The district engineer must approve the final mitigation plan before the permittee commences work in waters of of the the United States, unless the district engineer determines that prior approval final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation. If the prospective permittee elects to submit a compensatory mitigation plan with the PCN, the district engineer will expeditiously review the proposed compensatory mitigation plan. The district engineer must review the proposed compensatory mitigation plan within 45 calendar days of receiving a complete PCN and determine whether the proposed mitigation would ensure the NWP activity results in no more than minimal adverse environmental effects. If the net COASTAL ZONE MANAGEMENT ACT CONSISTENCY DETERMINATION (4/5117): Based on the comments submitted by the agencies administering the enforceable policies of the Virginia CZM Program, DEQ concurs that the 2017 NWPs and Virginia Regional Conditions as proposed, are consistent with the Virginia CZM Program provided the following conditions, discussed below, are satisfied: 1) Prior to construction, applicants shall obtain all required permits and approvals for activities to be performed that are applicable to the Virginia CZM Program's enforceable policies, and that applicants adhere to all the conditions contained therein. The Virginia Marine Resources Commission's (VMRC) concurrence of consistency with regard to the fisheries management, subaqueous hands management, wetlands management, and dunes management enforceable poliicies is based on the recognition that prospective permittees may be required to obtain additional state and/or local approvals from the VMRC and/or the local )wetlands board prior to commencement of work in both tidal and nontidal water -s under the agency's jurisdiction. Such approvals must precede implementation of the projects. - 2) The DEQ Office of Wetlands and Stream Protection ((OWSP) has provided §401 Clean Water Act (CWA) Water Quality Certification for the 2017 NWPs and Regional Conditions, applicable to the wetlands management and point source pollution control enforceable policies of the Virginia CZM Program. The activities that qualify for the NWPs must meet the requirements of DEQ's Virginia Water Protection Permit Regulation (9 VAC 25-210-130) and the permittee must abide by the conditions of the NWP. DEQ-OWSP has identified specific NWP exceptiions. DEQ will process an individual application for a permit or a certificate or otherwise take action pursuant to 9 VAC 25-210-80 et seq. for those activities covered by ain NWPs that have not received blanket §401 CWA Water Quality Certification. The Corps should forward pre -construction notifications to DEQ for applicants that do not comply with or cannot meet the conditions of the §401 CWA Water Quality Certification. Further, the Commonwealth reserves its dight to require an individual application for a permit or a certificate or otherwise take action on any specific project that could otherwise be covered under any of the NWPs when it determines on a case-by-case basis that concerns for water quality and the aquatic environment so indicate. In accordance with the Federal Consistency Regulations at 15 CFR Part 930, section 930. 4, this conditional concurrence is based on the applicants demonstrating to the Corps that they have obtained, or will obtain, all necessary authorizations prior to implementing a project which qualifies for a NWP. If the requirements of section 930. 4, sub -paragraphs (a)(1) through (a)(3) are not met, this conditional concurrence becomes an objection under 15 CFR Part 930, section 940.43. 12 M 27. Regional and Case -By -Case Conditions. The activity must comply with any regional conditions that may have been added by the Division Engineer (see 33 CFR 330.4(e)) and with any case specific conditions added by the Corps or by the state, Indian Tribe, or U.S. EPA in its section 401 Water Quality Certification, or by the state in its Coastal Zone Management Act consistency determination. 28. Use of Multiple Nationwide Permits. The use of more than one NWP for a single — — and complete project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed the acreage limit of the NWP with the highest specified acreage limit. For example, if a road crossing over tidal waters is constructed under NWP 14, with associated bank stabilization authorized by NWP 13, the maximum acreage loss of waters of the United States for the total project I cannot exceed 1/3 -acre. 29. Transfer of Nationwide Permit Verifications ' If the permittee sells the property assm�iated with a nationwide permit verification, the permittee may transfer the nationwide permit verification to the new owner by submitting a letter to the appropriate Corps district office to validate the transfer, A copy of the nationwide permit verification must be attached to the letter, and the letter must contain the. following statement and signature: "When the structures or work authorized by this nationwide permit are still in existence at the time the property is transferred, the terms and conditions of this nationwide permit, including any special conditions, will continue to be binding on the new owner(s) of the property. To validate the transfer of this nationwide permit and the associated liabilities associated with compliance with its terms and conditions, have the transferee sign and date below." (Transferee) (Date) 30. Compliance Certification. Each permittee who receives an NWP verification letter from the Corps Must provide a signed certification documenting completion of the authorized activity and implementation of any required compensatory mitigation. The success of any required permittee -responsible mitigation, including the achievement of ecological performance standards, will be addressed separately by the district engineer. The Corps will provide the permittee the certification document with the NWP verification letter. The certification document will include: (a) A statement that the authorized activity was done in accordance with the NWP authorization, including any general, regional, or activity -specific conditions; (b) A statement that the implementation of any required compensatory mitigation was completed in accordance with the permit conditions. If credits from a mitigation bank or in -lieu fee program are used to satisfy the compensatory mitigation requirements, the certification must include the documentation required by 33 CFR 332.3(i)(3) to confirm that the permittee secured the appropriate number and resource type of credits; and adverse environmental effects of the NWP activity (after consideration of the mitigation proposal) are determined by the district engineer to be no more than minimal, the district engineer will provide a timely written response to the applicant. The response will state that the NWP activity can proceed under the terms and conditions of the NWP, including any activity -specific conditions added to the NWP authorization by the district engineer. 4. If the district engineer determines that the adverse environmental effects of the proposed activity are more than minimal, then the district engineer will notify the applicant either: (a) that the activity does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit; (b) that the activity is authorized under the NWP subject to the applicant's submission of a mitigation plan that would reduce the adverse environmental effects so that they are no more than minimal; or (c) that the activity is authorized under the NWP with specific modifications or conditions. Where the district engineer determines that mitigation is required to ensure no more than minimal adverse environmental effects, the activity will be authorized within the 45 -day PCN period (unless additional time is required to comply with general conditions 18, 20, and/or 31, or to evaluate PCNs for activities authorized by NWPs 21, 49, and 50), with activity -specific conditions that state the mitigation requirements. The authorization will include the necessary conceptual or detailed mitigation plan or a requirement that the applicant submit a mitigation plan that would reduce the adverse environmental effects so that they are no more than minimal. When compensatory mitigation is required, no work in waters of the United States may occur until the district engineer has approved a specific mitigation plan or has determined that prior approval of a final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation. Further Information: 1. District Engineers have authority to determine if an activity complies with the terms and conditions of an NWP. 2� NWPs do not obviate the need to obtain other federal, state, or local permits, approvals, or authorizations required by law. 3. NWPs do not grant any property rights or exclusive privileges. 4. NWPs do not authorize any injury to the property or rights of others. 5� NWPs do not authorize interference with any existing or proposed Federal project (see general condition 31). SECTION 401 WATER QUALITY CERTIFICATION (417/17): The State Water Control Board issued conditional §401 Water Quality Certification for NWP 42 as meeting the requirements of the Virginia Water Protection Permit Regulation, which serves as the Commonwealth's §401 Water Quality Certification, provided that: (1) the facility does not include an impoundment for irrigation; (2) compensation is required for permanent wetland or stream impacts that exceed 0.1 0 of an acre or 300 linear feet due to direct impacts or permanent back flooding; (3) any compensatory mitigation meets the requirements in the Code of Virginia, Section 62. 1-44.15:23 A through C.
