DISTRICT PUBLIC NOTICE – PROPOSAL

 

NATIONWIDE PERMIT REISSUANCE REQUEST FOR COMMENTS

 

On June 18, 2025, the U.S. Army Corps of Engineers (Corps) published in the Federal Register its proposal to reissue 56 existing nationwide permits (NWPs) and issue one new NWP. One NWP is not proposed for reissuance.

 

NWPs are general permits issued on a nationwide basis to streamline the authorization of activities that result in no more than minimal individual and cumulative adverse environmental effects. Many of the proposed NWPs require notification to the district engineer before commencing those activities, to ensure that the activities authorized by those NWPs cause no more than minimal individual and cumulative adverse environmental effects.  

 

National Issues Concerning the Proposed NWPs:

The Federal Register notice is the public’s opportunity to comment on the proposed NWPs, general conditions, and definitions.  Comments on national issues relating to these NWPs should be submitted to docket number COE-2025-0002 at www.regulations.gov, or by email to 2026nationwidepermits@usace.army.mil or by mail to U.S. Army Corps of Engineers, Attn: CECW-CO-R, 441 G Street NW, Washington, DC 20314-1000. Instructions for submitting comments are provided in the June 18, 2025 Federal Register notice. Comments on the proposed NWPs are due by July 18, 2025.

 

Regional Issues Concerning the Proposed NWPs, Including Regional Conditioning:

 Division engineers are authorized to add regional conditions specific to the needs and/or requirements of a particular region or state. Regional conditions are an important mechanism to help ensure that the adverse environmental effects of activities authorized by the NWPs are no more than minimal, both individually and cumulatively. Division engineers may also suspend or revoke specific NWPs in certain geographic areas (e.g., states or watersheds) or high-value aquatic systems where the adverse environmental effects caused by activities authorized by those NWPs may be more than minimal. An enclosure for this public notice (Enclosure 1) lists the proposed regional conditions currently under consideration by the North Atlantic Division for the Commonwealth of Virginia, including military installations in Northern Virginia within Baltimore District’s Area of Responsibility (AOR) and South Holston Lake in Nashville District’s AOR. The Norfolk District is seeking comments on the proposed regional conditions and seeking comments on the need for additional regional conditions to help ensure that the adverse environmental effects of activities authorized by the proposed NWPs are no more than minimal, individually and cumulatively. Unless otherwise noted, all proposed regional conditions listed on this enclosure are applicable for activities in the Commonwealth of Virginia, including military installations in Northern Virginia within Baltimore District’s Area of Responsibility (AOR) and South Holston Lake in Nashville District’s Area of Responsibility (AOR). Comments on regional issues relating to the proposed NWPs and proposed regional conditions should be sent to Norfolk District, Regulatory Branch at 803 Front Street, Norfolk VA 23510; ATTN: Melissa Nash or to melissa.a.nash@usace.army.mil. Comments relating to regional conditions are due by August 4, 2025. Similar public notices proposing regional conditions in other regions or states are being published concurrently by other division or district offices. After the final NWPs are issued, the final regional conditions will be issued after they are approved by the Division Commander.

401 Water Quality Certification and Coastal Zone Management Act:

States, tribes, and other certifying authorities will make their Clean Water Act Section 401 water quality certification (WQC) decisions after reviewing the proposed NWPs. States will make their Coastal Zone Management Act (CZMA) consistency determination decisions after reviewing the proposed NWPs.

Draft Decision Documents:

Draft decision documents for each of the proposed NWPs, which include environmental documentation prepared for the purposes of the National Environmental Policy Act, have been written by Corps Headquarters. The decision documents will address compliance of the NWPs with the requirements for issuance under the Corps’ general permit authority. These draft decision documents, as well as the proposed NWPs, are available for viewing at www.regulations.gov, docket number COE-2025-0002. Final decision documents will be prepared for the NWPs that are issued. 

Enclosed (Enclosure 2) is an index of the proposed NWPs and conditions. Anyone wishing to provide comments may obtain a full text copy of the NWPs through the Corps Home Page at https://www.usace.army.mil/Missions/Civil-Works/Regulatory-Program-and-Permits/Nationwide-Permits/, at www.regulations.gov in docket number COE-2025-0002, or at the following Federal Register address: https://www.federalregister.gov/documents/2025/06/18/2025-11190/proposal-to-reissue-and-modify-nationwide-permits.

ENCLOSURE 1

 

Norfolk District Proposed Regional Conditions for the

2026 Nationwide Permits (NWPs) Applicable in Virginia

(Including Northern Virginia Military Installations within Baltimore District’s Area of Responsibility and South Holston Lake within Nashville District)

 

I.   REGIONAL conditions applicable to all NWPs UNLESS OTHERWISE STATED:

1. Waters Containing Submerged Aquatic Vegetation (SAV) Beds:

This condition applies to: NWPs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22, 23, 24, 25, 27, 28, 29, 31, 32, 33, 35, 36, 37, 38, 39, 45, 48, 52, 53, 54, 55, 57, and 58.

 

A pre-construction notification (PCN) is required if work will occur in areas that contain submerged aquatic vegetation (SAV).  Information about SAV habitat can be found at the Virginia Institute of Marine Science’s website http://mobjack.vims.edu/sav/savwabmap/.  Additional avoidance and minimization measures, such as relocating a structure or time-of-year restrictions (TOYR), may be required to avoid or reduce impacts to SAV habitat.

 

                                                                                                                              

2. Anadromous Fish Use Areas:

Authorizations associated with the NWPs shall not adversely affect spawning habitat or a migratory pathway for anadromous fish. Areas of anadromous fish use are indicated on the Virginia Department of Wildlife Resources (DWR) information system at: https://services.dwr.virginia.gov/fwis/ . If a project is located within an area documented as an anadromous fish use area (confirmed or potential), all in-stream work is prohibited from occurring between February 15 through June 30 of any given year or other time of year restriction (TOYR) specified by the DWR, Virginia Marine Resources Commission (VMRC), and/or NOAA Fisheries Service. Should the Norfolk District determine that the work is minimal and no TOYR is needed, the District will initiate consultation with NOAA Fisheries Service for their concurrence. A TOYR is not required for dredging activities in the Elizabeth River upstream of the Mid-Town Tunnel on the main-stem and the West Norfolk Bridge (Route 164, Western Freeway) on the Western Branch of the Elizabeth River.

 

3. Designated Critical Resource Waters, which include National Estuarine Research Reserves:

A PCN is required for work under NWPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, 38 and 54 in the Chesapeake Bay National Estuarine Research Reserve in Virginia.  This multi-site system along a salinity gradient of the York River includes Sweet Hall Marsh, Taskinas Creek, Catlett Islands, and Goodwin Islands.  More information can be found at: http://www.vims.edu/cbnerr/.   

 

NWPs 7, 12, 14, 16, 17, 29, 31, 35, 39, 40, 42, 43, 44, 49, 50, 51, 52, 57 and 58 cannot be used to authorize the discharge of dredged or fill material in the Chesapeake Bay National Estuarine Research Reserve in Virginia.

 

 

4. Federally Listed Threatened or Endangered Species and Designated Critical Habitat for Non-Federal Permittees

 

For ALL NWPs, a PCN is required for any project that may affect a federally listed threatened or endangered species or designated critical habitat.  The U.S. Fish and Wildlife Service (Service) has developed an online system that allows users to find information about sensitive resources that may occur within the vicinity of a proposed project. This system named “Information, Planning and Conservation System” (IPaC), is located at: http://ecos.fws.gov/ipac/ . The applicant may use IPaC to determine if any federally listed threatened or endangered species or designated critical habitat may be affected by their proposed project.  If your Official Species List from IPaC identifies any federally listed threatened or endangered species, you are required to submit a PCN for the proposed activity, unless the project clearly does not impact a listed species or suitable habitat for the listed species.  If you are unsure about whether your project will impact federally listed threatened or endangered species, please submit a PCN, so the Norfolk District may review the action.  Further information about the Virginia Field Office “Project Review Process” may be found at:  http://www.fws.gov/northeast/virginiafield/endangered/projectreviews.html.

 

Additional consultation may also be required with NOAA Fisheries Service, Protected Resources Division, for listed species or critical habitat under their jurisdiction, including sea turtles, marine mammals, shortnose sturgeon, and Atlantic sturgeon.  For additional information about species under their jurisdiction in Virginia, please see https://www.fisheries.noaa.gov/new-england-mid-atlantic/consultations/section-7-consultations-greater-atlantic-region .   

 

 

5. Invasive Species

 

Plant species listed in the most current Virginia Department of Conservation and Recreation’s (DCR) Invasive Alien Plant List shall not be used for re-vegetation for activities authorized by any NWP. The list of invasive plants in Virginia is found at:

https://www.dcr.virginia.gov/natural-heritage/invsppdflist.  DCR recommends the use of regional native species for re-vegetation as identified in the DCR Native Plants for Conservation, Restoration and Landscaping brochures for the coastal, piedmont and mountain regions http://www.dcr.virginia.gov/natural-heritage/nativeplants#brochure also see the DCR native plant finder: https://www.dcr.virginia.gov/natural-heritage/native-plants-finder.

 

 

6. Countersinking Pipes and Culverts

 

This condition applies to: NWPs 3, 7, 12, 14, 17, 18, 23, 25, 27, 29, 32, 33, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 49, 50, 51, 52, 57, and 58.

 

NOTE FOR WORK IN TIDAL WATERS: New and replacement pipes/culverts in tidal waters must be installed with the inverts no higher than the prevailing stream/channel bottom elevation. If the permittee determines that matching existing elevations is not practicable, then a PCN is required. This condition does not apply to pipe extensions in tidal waters.

 

Based on consultation with DWR, the Norfolk District has determined that fish and other aquatic organisms are most likely present in any nontidal stream being crossed, in the absence of site-specific evidence to the contrary. The following conditions will apply in nontidal waters:

     

1. All pipes and culverts placed in streams will be countersunk at 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.

 

2. 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. 

 

3. The requirement to countersink does not apply to extensions of existing pipes or culverts that are not countersunk, or to maintenance to pipes/culverts that does not involve replacing the pipe/culvert (such as repairing cracks, adding material to prevent/correct scour, etc.).

 

4. 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).

 

5. 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.

 

6. 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:

 

1. Replacement of an existing pipe/culvert: Countersinking is not 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/culvert. Documentation (photographic or other evidence) must be maintained in the permittee’s records showing the bedrock condition and the existing inlet and outlet elevations.

 

2. A pipe/culvert is being placed in a new location: If the permittee determines that bedrock or an existing buried utility line that is not practicable to relocate prevents countersinking, they should evaluate the use of a bottomless pipe/culvert, bottomless utility vault, span (bridge) 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 permittee determines that neither a bottomless structure nor an alternative location is practicable, then a PCN is required.  The permittee must provide documentation of measures evaluated to minimize disruption of the movement of aquatic life as well as documentation of the cost, engineering factors, and site conditions that prohibit countersinking the pipe/culvert. Options that must be considered include partial countersinking (such as less than 3” of countersinking, or countersinking of one end of the pipe), and constructing stone step pools, low rock weirs downstream, or other measures to provide for the movement of aquatic organisms. PCN must also include photographs documenting site conditions. NOTE: Blasting of stream bottoms through the use of explosives is not acceptable as a means of providing for countersinking of pipes on bedrock.

 

7. 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 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 permittee not want to countersink the pipe/culvert for other reasons, they must submit a PCN. The permittee must provide documentation of measures evaluated to minimize disruption of the movement of aquatic life as well as documentation of the cost, engineering factors, and site conditions that prohibit countersinking the pipe/culvert. The 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 below the plane of ordinary high water) must be included in project totals.

 

8. 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 NWP.

 

1. 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 can be replaced as it was before the washout, but the permittee will have to come back and replace the pipe/culvert and countersink it in accordance with the guidance above.  In other words, the replacement of the washed out pipe is viewed as a temporary repair, and a countersunk replacement should be made at the earliest possible date. The Norfolk District must be notified of all pipes/culverts that are replaced without countersinking at the time that it occurs, even if it is an otherwise non-reporting activity, and must provide the permittee's planned schedule for installing a countersunk replacement (it is acceptable to submit such notification by email). The permittee should anticipate whether bedrock or steep terrain will limit countersinking, and if so, should follow

the procedures outlined in (f) and/or (g) above.

 

 

7. Repair of Pipes

 

This condition applies to: NWPs 3, 7, 12, 14, 17, 18, 23, 25, 27, 29, 32, 33, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 49, 50, 51, 52, 57, and 58.

 

NOTE FOR WORK IN TIDAL WATERS: New and replacement pipes/culverts in tidal waters must be installed with the inverts no higher than the prevailing stream/channel bottom elevation. If the permittee determines that matching existing elevations is not practicable, then a PCN is required. This condition does not apply to pipe extensions in tidal waters.

 

For Nontidal Waters: If any discharge of fill material will occur in conjunction with pipe maintenance, such as concrete being pumped over rebar into an existing deteriorated pipe for stabilization, then the following conditions apply:

 

1. If the existing pipe or multi-barrel array of pipes are NOT currently countersunk:

 

1. As long as the inlet and outlet invert elevations of at least one pipe located in the low flow channel are not being altered, and provided that no concrete apron is being constructed, then the work may proceed under the NWP for the other pipes, provided it complies with all other NWP General Conditions. In such cases, a PCN is not required, unless specified in the Regional Conditions for other reasons, and the permittee may proceed with the work.

 

2. Otherwise, the permittee must submit a PCN prior to commencing the activity. For all such projects, the following information should be provided:

 

1. Photographs of the existing inlet and outlet;
2. A measurement of the degree to which the work will raise the invert elevations of both the inlet and outlet of the existing pipe;
3. The reasons why other methods of pipe maintenance are not practicable (such as metal sleeves or a countersunk pipe replacement);
4. A vicinity map showing the pipe locations.

 

The Norfolk District will assess all such pipe repair proposals in accordance with guidelines that can be found under “Pipe Repair Guidelines” at:

 

http://www.nao.usace.army.mil/Missions/Regulatory/GuidanceDocuments.aspx

 

3. If the Norfolk District determines that the work qualifies for the NWP, additional conditions will be placed on the verification.  Those conditions can be found at the web link above (in item ii).

 

4. If the Norfolk District determines that the work does NOT qualify for the NWP, the applicant will be directed to apply for either Regional Permit 01, applicable only for Virginia Department of Transportation (VDOT) projects or an Individual Permit. However, it is anticipated that the applicant will still be required to perform the work such that the waterway is not blocked or restricted to a greater degree than its current conditions.

 

2. If the existing pipe or at least one pipe in the multi-barrel array of pipes IS countersunk and at least one pipe located in the low flow channel will continue to be countersunk, and no concrete aprons are proposed:

 

No PCN to the Norfolk District is required, unless specified in the Regional Conditions for other reasons, and the permittee may proceed with the work.

 

3. If the existing pipe or at least one pipe in the multi-barrel array of pipes IS countersunk and no pipe will continue to be countersunk in the low flow channel:

 

This work cannot be performed under the NWPs. The permittee must apply for either a Regional Permit 01 (applicable only for VDOT projects) or an Individual Permit. However, it is anticipated that the permittee will still be required to perform the work such that the waterway is not blocked or restricted more so than its current conditions.

 

4. In emergency situations, if conditions or timeframes do not allow for compliance with the procedure outlined herein, then the pipe can be temporarily repaired to the condition before the washout.  If the temporary repair would require a PCN by the above procedures, the permittee must submit the PCN at the earliest practicable date, but no longer than 15 days after the temporary repair.  

 

8.         Impacts Requiring a Compensatory Mitigation Plan

 

When a PCN is required, a compensatory mitigation plan must be submitted if the permanent loss exceeds 0.1 acre of wetlands and/or 0.03 acre of stream bed or 300 linear feet of stream bed unless otherwise stated in the regional conditions (see Regional Condition 11 for Transportation Projects).  The stream channel loss must be reported in acreage and linear feet.     

 

9.       Removal of Temporary Fills and Impacts

 

The soils of any temporarily impacted areas located in wetlands that are cleared, grubbed, excavated, dredged and/or filled, must be restored once these areas are no longer needed for their authorized purpose, no later than completion of project construction, and not to exceed twelve (12) months after commencing the temporary impacts. To restore, temporary fill must be removed in its entirety and the affected areas returned to preconstruction elevations, the soil surface loosened by ripping or chisel plowing to a depth of 8-12”, and then seeded using native wetland species. See Regional Condition 6: Invasive Species for more information on vegetation recommendations.

 

Fill or dredged material in waters of the U.S. that is not removed within the 12-month period will be considered a permanent impact, unless otherwise

determined by the Corps. This additional impact to waters of the U.S. may result

in the Corps initiating a permit non-compliance action, which may include a restoration order, after-the-fact permitting, and/or compensatory mitigation.

 

 

10.       Transportation Projects Funded in Part or in Total by Local, State or                Federal Funds

 

For all impacts associated with transportation projects funded in part or in total by local, state or federal funds and requiring a PCN, compensatory mitigation will generally be required for all permanent wetland impacts (including impacts less than 1/10 acre).  Therefore, the PCN must include a compensatory mitigation plan.

 

 

11.      Activities Affecting Structures or Works Built by the United States

 

A PCN is required if the NWP activity also requires a section 408 permission from the Corps pursuant to 33 U.S.C. 408 because it will alter or temporarily or permanently occupy or use a Corps federally authorized Civil Works project. The activity is not authorized by the NWP until the appropriate Corps District office issues the section 408 permission and the District Engineer issues a written NWP verification [NWP GC #31 and GC #32(b)(1)].

 

The locations of Norfolk District Civil Works projects can be found on the Norfolk District Section 408 Program webpage at: https://www.nao.usace.army.mil/408Review/ via the Norfolk District Section 408 Map.

 

Four other Corps Districts, including the Baltimore, Huntington, Nashville and Wilmington Districts, have civil works boundaries within the Commonwealth of Virginia. Please see the USACE Civil Works Boundary layer in the Norfolk District Section 408 Map on the Norfolk District Section 408 Program webpage. If your project is located within the civil works boundaries of another District, please contact the corresponding District’s Section 408 Coordinator for more information via the links provided on the Norfolk District Section 408 Program webpage.

Please contact the Norfolk District Section 408 Coordinator at nao.section408@usace.army.mil for any questions or additional information.

 

 

12.       Clean Water Act Section 401 Water Quality Certification

 

To be determined through ongoing consultation with VDEQ.

 

 

13.      Federal Consistency under the Coastal Zone Management Act (CZMA)

 

            To be determined through ongoing consultation with VDEQ.

 

II. Regional Conditions Applicable To Specific 2021 NWPs:

 

 

NWP 5 - Scientific Measurement Devices

Condition for Construction or Installation of Subaqueous Turbines: 

 

A PCN is required if a permittee proposes the construction or installation of subaqueous turbines because this work may have more than minimal impacts and the work will need to be coordinated with appropriate federal, state, and/or local agencies.

 

 

NWP 7 - Outfall Structures and Associated Intake Structures

Conditions for Intakes in Anadromous Fish Waters:

 

When an intake is proposed in designated anadromous fish waters, the following design parameters will be incorporated as permit conditions to protect the sensitive life stages of shellfish, resident and anadromous fish:

 

1. Screening over the mouth of the intake with mesh size that does not exceed 1mm;

 

2. Intake velocities that do not exceed 0.25 feet per second;

 

3. Intake must be positioned such that an unimpeded flow of water parallel to the screen surface occurs along the entire surface of the screen to take advantage of sweeping velocity.

 

 

NWP 10 - Mooring Buoys

Conditions for Sufficient Mooring Depths:

 

1. Water depths in the mooring areas should be sufficient that vessels moored float at all stages of the tide. 

 

2. Boats should not hit bottom during low water conditions.  The swing radius of the vessel plus the mooring chain should not result in the vessel becoming an obstruction to navigation. 

 

3. Use of this NWP is prohibited in and around SAV beds.  Information about SAV habitat can be found at the Virginia Institute of Marine Science’s website http://mobjack.vims.edu/sav/savwabmap/.

 

 

NWP 11 - Temporary Recreational Structures

Conditions for Sufficient Mooring Depths:

 

1. Water depths in the mooring areas should be sufficient that structures moored float at all stages of the tide or stoppers must be utilized to prevent the structures from resting on the bottom, so as to not damage the underlying benthic communities. 

 

2. Structures should not hit bottom during low water conditions. 

 

3. Use of this NWP is prohibited in and around SAV beds.  Information about SAV habitat can be found at the Virginia Institute of Marine Science’s website http://mobjack.vims.edu/sav/savwabmap/.  

 

NWP 12 - Oil or Natural Gas Pipeline Activities

Conditions Specific to NWP 12:

 

1. Construction of access roads may not cause the loss of more than 1/3 acre of waters of the United States. 

 

2. A PCN is required when the activity involves greater than 0.10 acre of mechanized landclearing in a forested wetland for the utility line right-of-way.

 

3. For utility activities requiring a PCN the permittee shall provide the following information:

 

1. A map of the entire utility corridor to assist with our completeness determination.  The map should include a delineation of all wetlands and waters of the United States within the corridor.  Aquatic resource information shall be submitted using the Cowardin Classification System mapping conventions (e.g. PFO, PEM, POW, etc.).

 

2. An analysis of onsite minimization, which specifically addresses the following:

 

1. Selection of an alignment which avoids and minimizes wetland and stream impacts to the maximum extent practicable.  The utility line should make a direct or perpendicular crossing of a stream.  Directional drilling should be reviewed as an option.  However, the Norfolk District recognizes that in certain areas (e.g. karst areas) directional drilling may not be the environmentally preferred option.

 

2. Selection of an alignment which avoids fragmenting large tracts of forested wetlands by routing utility lines outside of forested tracts or on the edges of forested tracts. Consult the Virginia Conservation Vision, a GIS analysis for identifying and prioritizing areas of un-fragmented natural cover in Virginia http://www.dcr.virginia.gov/natural-heritage/vaconvision or the Virginia Natural Heritage Data Explorer (http://vanhde.org/content/map).   

 

3. Minimizing clearing of wetlands. Grubbing shall be limited to the permanent easement for underground utility lines.  Outside of the permanent easement, wetland vegetation shall only be removed at or above the ground surface unless written justification is provided, and the impacts are reviewed and approved by the Corps.

 

4. For buried utility lines, allowance of natural succession to restore the wetland area to tree and scrub/shrub except for a 20-foot wide access corridor, to the maximum extent practicable.

 

3. Compensatory mitigation may be required for permanent conversion of wetlands within the utility line corridor. 

 

4. For all submerged and overhead utility lines across navigable waters of the United States, a location map and cross-sectional view showing the utility line crossing from bank to bank is required, including the proposed burial depth (in feet relative to mean low water) or minimum clearance height (feet) per 33 CFR 322.5(i).  In addition, the location and maximum authorized depths of any Federal navigation channels must be shown in relation to the proposed utility line on the plan view and cross-section view of the project plans. The locations of Norfolk District Federal Projects can be found on the Norfolk District Section 408 Program webpage at: https://www.nao.usace.army.mil/408Review/ via the Norfolk District Section 408 Map. Section 408 permission will be required pursuant to 33 U.S.C. 408 for any utility lines that cross over or under a Federal project.  Any utility lines crossing under a Federal navigation channel must be buried to a minimum depth to mitigate potential impacts to navigation and/or the operation and maintenance of the Federal project. Specific minimum depth requirements under the Federal channel and side slopes, and within the vicinity of the channel outside the side slopes must be coordinated with the Norfolk District Section 408 Coordinator and as part of the required Section 408 request. It is recommended that all utility line crossings be designed to allow for adequate depths or other protective measures installed below the maximum authorized dredge depths of the federal project and side slopes to avoid impacts during dredging work and to protect the utility line from unintended damage from dredging, anchors and/or other equipment and vessels.  Please contact the Norfolk District Section 408 Coordinator at nao.section408@usace.army.mil for more information and maximum authorized depths for specific Federal navigation projects or other federal project footprints.

 

5. Whenever practicable, excavated material shall be placed on a Corps confirmed upland site, scow or barge. However, when this is not practicable, temporary stockpiling is authorized provided that:

 

1. All excavated material stockpiled in a vegetated wetland area is placed on filter cloth, mats, or some other semi-permeable surface. The material will be stabilized with straw bales, filter cloth, etc. to prevent reentry into any waterway.

 

2. All excavated material must be placed back into the trench to the original contour and all excess excavated material must be completely removed from the wetlands within 30 days after the pipeline has been laid through the wetland areas. Permission must be granted by the Norfolk District if the material is to be stockpiled longer than 30 days.

 

6. The applicant must receive written verification before performing the work when open-cut trenching, temporary stockpiling dredge material, or hydrostatic testing of a pipeline involving water withdrawals in designated anadromous fish use areas is proposed. For project sites within anadromous fish use areas, time-of-year restrictions (TOYRs) from February 15 through June 30 of any given year will apply, unless coordination with NOAA and/or the DWR results in a different TOYR or none.

5. Information concerning competing uses of the waterbody above the dam if the impoundment is not fully owned by the applicant.

 

 

NWP 54-Living Shorelines

 

1. This activity authorizes the placement of sandy fill material, including the placement landward of sill(s) provided the fill is for shoreline protection and/or wetland establishment or enhancement (and not solely a recreational beach).  The maximum fill area within waters of the United States that can be authorized under this NWP is one (1) acre.  For the purpose of this NWP, a sill is defined as a low (not to exceed +1 ft. above MHW), detached structure constructed near shore and parallel to the shoreline for the purpose of building up an existing beach by trapping and retaining sand in the littoral zone.  Because a sill acts like a natural bar, it is most effective when constructed at or near the mean low water line and low enough to allow wave overtopping. 

 

2. The grain size of the source material used for fill must be beach quality sand that is the same size or slightly larger than that of the native beach material and suitable for the proposed project.  Excess silt/clay fraction and grain sizes smaller than the former native sands will perform poorly.  In most cases, sand material with no more than 10% passing a #100 sieve is appropriate. All fill material will be obtained from either an upland source, a borrow pit, or dredge material approved by the Corps. 

 

3. Coir logs, coir mats, and native oyster shell should be of sufficient weight, adequately anchored, or placed in a manner to prevent them from being dislodged or carried away by wave action.

 

4. Sills may be constructed of riprap stone, gabion baskets, or clean broken concrete free of metal and re-bar.  Alternative materials may be considered for use during the permit review process.  The materials should be of sufficient weight or adequately anchored to prevent them from being dislodged and carried away by wave action.  Asphalt and materials containing asphalt or other contaminants shall not be used in the construction of sills. 

 

5. Sills will be designed with at least one 5-foot window/gap per property and per 100 linear feet of sill unless waived by the District Engineer.

 

6. The sill height should be a maximum of +1 foot above mean high water and should be placed at a distance no greater than 30 feet from mean low water to the channelward toe of the sill unless waived by the District Engineer.

 

7. The total amount of existing vegetated wetlands, which may be filled, graded, or excavated, in square feet, may not exceed the length of the activity along the shoreline in linear feet unless the District Engineer waives this criterion by making a written determination concluding that the project will result in minimal adverse effects. Impacts to sub-tidal, inter-tidal, and/or existing wetland vegetation may require a wetland mitigation plan and must result in no net loss of vegetated wetlands.

 

8. If the proposed project results in impacts to existing wetland vegetation, then a written monitoring report may be required at the end of the first full growing season following planting, and after the second year of establishment. If required, the monitoring should be undertaken between June and September of each year and should include at a minimum: the project location, the Corps project number, representative photos of the site, and a brief statement on the success of the project.

 

9. As the design of a living shoreline project is site specific, it is suggested that the applicant refer to the Virginia Institute of Marine Sciences Living Shoreline Design Guidelines for Shore Protection in Virginia’s Estuarine Environments and other reference documents which can be found at: https://www.vims.edu/ccrm/outreach/living_shorelines/index.php

 

10. Projects which include placement of sandy fill material may result in impacts to or creation of suitable habitat for various federally listed threatened or endangered species. If this occurs or the applicant seeks to either add to or replenish the area previously filled, the Corps will consult with the U.S. Fish and Wildlife Service pursuant to Section 7 of the Endangered Species Act to ensure work is not likely to adversely affect proposed or listed species or proposed or designated critical habitat. Specific requirements on the type of sand allowed for beach and dune work may be required.

 

 

NWP 55- Seaweed Mariculture Activities

 

In addition to the information required under NWP B, the followings should be included in the PCN:

 

1. General water depths, sediment characteristics of the bottom substrate, and benthic species present (including submerged aquatic vegetation) in the project area(s) (a detailed survey is not required).

 

2. A description of the quantity and dimensions of all proposed structure(s), including: culture gear (lines, cages pens, etc.), anchors, and site markers.

 

3. A vicinity map showing the project location(s), including the longitude and latitude of the site boundaries.

 

4. A schematic or drawing showing how the gear will be deployed on the site (a formal engineered schematic is not required).

 

5. The name(s), including sub-species if applicable, and quantities of the species that will be cultivated.

 

 

NWP 57- Electric Utility Line and Telecommunications Activities

 

1. Construction of access roads may not cause the loss of more than 1/3 acre of waters of the United States.

 

2. A PCN is required when the activity involves greater than 0.10 acres of mechanized landclearing in a forested wetland for the utility line right-of-way. 

 

3. For utility activities requiring a PCN the permittee shall provide the following information:

 

1.

Grubbing shall be limited to the permanent easement for underground utility lines.  Outside of the permanent easement, wetland vegetation shall only be removed at or above the ground surface unless written justification is provided, and the impacts are reviewed and approved by the Corps.

 

4. For overhead utility lines, allowance of natural succession to restore and maintain the corridor in scrub-shrub wetlands except for a minimum corridor needed for access, to the maximum extent practicable.

 

5. For buried utility lines, allowance of natural succession to restore the wetland area to tree and scrub/shrub except for a 20-foot wide access corridor, to the maximum extent practicable.

 

3. Compensatory mitigation may be required for permanent conversion of wetlands within the utility line corridor. 

 

4. For all submerged and overhead utility lines across navigable waters of the United States, a location map and cross-sectional view showing the utility line crossing from bank to bank is required, including the proposed burial depth (in feet relative to mean low water) or minimum clearance height (feet) per 33 CFR 322.5(i).  In addition, the location and maximum authorized depths of any Federal navigation channels must be shown in relation to the proposed utility line on the plan view and cross-section view of the project plans. The locations of Norfolk District Federal Projects can be found on the Norfolk District Section 408 Program webpage at: https://www.nao.usace.army.mil/408Review/ via the Norfolk District Section 408 Map. Section 408 permission will be required pursuant to 33 U.S.C. 408 for any utility lines that cross over or under a Federal project.  Any utility lines crossing under a Federal navigation channel must be buried to a minimum depth to mitigate potential impacts to navigation and/or the operation and maintenance of the Federal project. Specific minimum depth requirements under the Federal channel and side slopes, and within the vicinity of the channel outside the side slopes must be coordinated with the Norfolk District Section 408 Coordinator and as part of the required Section 408 request. It is recommended that all utility line crossings be designed to allow for adequate depths or other protective measures installed below the maximum authorized dredge depths of the federal project and side slopes to avoid impacts during dredging work and to protect the utility line from unintended damage from dredging, anchors and/or other equipment and vessels.  Please contact the Norfolk District Section 408 Coordinator at nao.section408@usace.army.mil for more information and maximum authorized depths for specific Federal navigation projects or other federal project footprints.

 

 

5. Whenever practicable, excavated material shall be placed on a Corps confirmed upland site, scow or barge. However, when this is not practicable, temporary stockpiling is hereby authorized provided that:

 

1. All excavated material stockpiled in a vegetated wetland area is placed on filter cloth, mats, or some other semi-permeable surface. The material will be stabilized with straw bales, filter cloth, etc. to prevent reentry into any waterway.

 

2. All excavated material must be placed back into the trench to the original contour and all excess excavated material must be completely removed from the wetlands within 30 days after the pipeline has been laid through the wetland areas. Permission must be granted by the Norfolk District if the material is to be stockpiled longer than 30 days.

 

6. The applicant must receive written verification before performing the work when open-cut trenching, temporary stockpiling dredge material, or hydrostatic testing of a pipeline involving water withdrawals in designated anadromous fish use areas is proposed. For project sites within anadromous fish use areas, time-of-year restrictions (TOYRs) from February 15 through June 30 of any given year may apply, unless coordination with NOAA and/or the DWR results in a different TOYR or none.  

 

7. Aerial Transmission Lines Crossing Navigable Waters:

 

a. The following minimum clearances are required for aerial electric power transmission lines crossing navigable waters of the United States. These clearances are related to the clearances over the navigable channel provided by existing fixed bridges, or the clearances which would be required by the United States Coast Guard for new fixed bridges, in the vicinity of the proposed aerial transmission line. These clearances are based on the low point of the line under conditions producing the greatest sag, taking into consideration temperature, load, wind, length of span, and type of supports as outlined in the National Electrical Safety Code

 

Nominal System Voltage (kV)	Minimum additional clearance (ft.) above clearance required for bridges
115 and below	20
138	22
161	24
230	26
350	30
500	35
700	42
750 - 765	45

 

b. Clearances for communication lines, stream gaging cables, ferry cables, and other aerial crossings must be a minimum of ten feet above clearances required for bridges, unless otherwise specifically authorized by the District Engineer.

 

c. Corps of Engineer regulation ER 1110-2-4401 prescribes minimum vertical clearances for power communication lines over Corps lake projects. In instances where both this Regional Condition and ER 1110-2-4401 apply, the greater minimum clearance is required.

 

8. For utility lines landing in Virginia, from the Outer Continental Shelf (OCS), the applicant shall send the PCN to the following federal agencies:

 

Director, Naval Seafloor Cable Protection Office

Naval Facilities Engineering Command

1322 Patterson Ave SE, Suite 1000

Washington DC 20374  

 

Bureau of Ocean Energy Management (BOEM)

Atlantic OCS Region

1201 Elmwood Park Blvd.

New Orleans, LA 70123-2394.

 

9. For utility line projects completed by horizontal directional drilling or other boring methods, a plan to address the prevention, containment, and cleanup of sediment or other materials caused by inadvertent returns of drilling fluids to waters of the U.S. through sub-soil fissures or fractures needs to be included with the PCN (if a PCN is required).  If an inadvertent return of drilling fluids to waters of the U.S. occurs, and the remediation requires work within waters of the U.S., then the applicant must notify the Corps immediately and submit a remediation plan as soon as possible, regardless of whether a PCN was required for the original work.

 

10. When an intake is proposed in designated anadromous fish waters, the following design parameters will be incorporated as permit conditions to protect the sensitive life stages of anadromous fish:

 

a. Screening over the mouth of the intake with mesh size that does not exceed 1mm;

b. Intake velocities that do not exceed 0.25 feet per second;

c. Intake must be positioned such that an unimpeded flow of water parallel to the screen surface occurs along the entire surface of the screen to take advantage of sweeping velocity.

 

 

NWP 58- Utility Line Activities for Water and Other Substances

 

1. Construction of access roads may not cause the loss of more than 1/3 acre of waters of the United States.  

 

2. A PCN is required when the activity involves greater than 0.10 acres of mechanized landclearing in a forested wetland for the utility line right-of-way. 

 

3. For utility activities requiring a PCN the permittee shall provide the following information:

 

1. A map of the entire utility corridor to assist with our completeness determination.  The map should include a delineation of all wetlands and waters of the United States within the corridor.  Aquatic resource information shall be submitted using the Cowardin Classification System mapping conventions (e.g. PFO, PEM, POW, etc.).

 

2. An analysis of onsite minimization, which specifically addresses the following:

 

1. Selection of an alignment which avoids and minimizes wetland and stream impacts to the maximum extent practicable.  The utility line should make a direct or perpendicular crossing of a stream.  Directional drilling should be reviewed as an option.  However, the Norfolk District recognizes that in certain areas (e.g. karst areas) directional drilling may not be the environmentally preferred option.

 

2. Selection of an alignment which avoids fragmenting large tracts of forested wetlands by routing utility lines outside of forested tracts or on the edges of forested tracts. Consult the Virginia Conservation Vision, a GIS analysis for identifying and prioritizing areas of un-fragmented natural cover in Virginia http://www.dcr.virginia.gov/natural-heritage/vaconvision.

 

3. Minimizing clearing of wetlands. Grubbing shall be limited to the permanent easement for underground utility lines.  Outside of the permanent easement, wetland vegetation shall only be removed at or above the ground surface unless written justification is provided and the impacts are reviewed and approved by the Corps.

 

4. For overhead utility lines, allowance of natural succession to restore and maintain the corridor in scrub-shrub wetlands except for a minimum corridor needed for access, to the maximum extent practicable.

 

5. For buried utility lines, allowance of natural succession to restore the wetland area to tree and scrub/shrub except for a 20-foot wide access corridor, to the maximum extent practicable.

 

3. Compensatory mitigation may be required for permanent conversion of wetlands within the utility line corridor.
