CENAO-WRR

18-RP-02

REGIONAL PERMIT

Effective Date: September 5, 2018 Expiration Date: September 5, 2023

I. AUTHORIZED ACTIVITIES:

18-RP-02, Regional Permit 02 (RP), authorizes both new and maintenance dredging (channels and basins) for certain navigation-related dredging projects, by either mechanical or hydraulic method, in waters of the U.S. This RP authorizes these activities within the geographical limits of the Commonwealth of Virginia under the regulatory jurisdiction of the Norfolk District Army Corps of Engineers (Corps), subject to the terms and conditions further set out herein:

1. Maintenance Dredging for Previously Authorized Projects:

a. For the purposes of this Regional Permit (RP), maintenance dredging means dredging only within the actual areas and to the actual depths dredged, as authorized with the most recent Department of the Army (DA) Permit.

b. Prospective permittees must document that a previous DA permit authorized dredging in the project area. The prospective permittee must demonstrate that the project area proposed for maintenance dredging does not exceed the limits specified in the previous DA Permit.

2. New Dredging:

a. The dredging authorized by this permit shall not exceed a surface area of two (2) acres.

b. The depth of dredging of access channels shall not exceed controlling depths of ingress/egress.

c. Newly dredged channels shall have a bottom width of at least 20 feet, unless the Corps determines that a narrower channel would not compromise safe navigation and the 20-foot minimum is waived in writing by the District Engineer.

d. In tidal waters, dredging is limited to areas below mean low water.

e. In non-tidal waters, dredging is limited to areas below the Ordinary High

Water Mark (OHWM).

18-RP-02 2

3. Discharges of Dredged Material into Waters of the U.S. associated with Maintenance or New Dredging:

a. This RP authorizes, pursuant to Section 404 of the Clean Water Act, a discharge of dredged material, other than incidental fallback1, into non-tidal waters of the U.S. for the following activities:

i. Discharge of Dredged Material Due to Dredging Method: Certain types of dredging methods (i.e. mechanical) often result in a discharge (redeposit) of dredged material into the water of the U.S. during operation. This discharge is authorized with this RP provided:

1. The permittee demonstrates, to the satisfaction of the Corps, that the discharge of dredged material associated with the method of dredging is unavoidable.

2. The permittee demonstrates, to the satisfaction of the Corps, that the discharge of dredged material associated with the method of dredging would be minimized to the maximum extent practicable.

3. The discharge (redeposit) of dredged material into waters would occur only as a result of the dredging method.

4. The discharge (redeposit) of dredged material into waters would only occur within the footprint of the dredging activity.

5. The total amount of dredged material would not exceed 5,000 cubic yards.

6. The total surface area of dredging would not exceed two (2) contiguous acres.

ii. Discharge of Return Water from Disposal Area: The return water from a contained disposal area is administratively defined as a discharge of dredged material2, even though the disposal area itself may not be located in a waters of the U.S. The discharge is authorized with this RP provided:

1. The quality of the return water is regulated by the state through the

Section 401 certification procedures.

II. AUTHORITIES:

For projects located within the Commonwealth of Virginia, project proponents are hereby authorized by the Secretary of the Army and the Chief of Engineers pursuant to Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. § 403) and/or Section 404 of the Clean Water Act (33 U.S.C. § 1344) to perform the aforementioned work in waters of the U.S. pursuant to the terms and conditions herein.

1 33 CFR323.2(d)(2) 2 33 CFR 323.2(d)(1)(ii)

18-RP-02 3

Activities receiving written authorization under this RP do not require further authorization under the provisions contained in 33 CFR Part 325 unless the District Engineer determines, on a case-by-case basis, that additional review is in the public interest. All work undertaken outside the following conditions, terms, and limitations will require separate Department of the Army authorization.

III. STATE AND LOCAL APPROVALS:

1. Prospective permittees may be required to obtain additional state and/or local approvals prior to commencement of work in waters of the U.S. from the Virginia Department of Environmental Quality (DEQ), the Virginia Marine Resources Commission (VMRC) and/or the local wetlands board. You may contact the DEQ at (804) 698-4000, the VMRC at (757) 247-2200 and/or local government office for further information concerning permit requirements.

2. The State Water Control Board provided conditional §401 Water Quality Certification for the 18-RP-02. As such, the activities that qualify for this RP meet the requirements of Department of Environmental Quality’s (DEQ) Virginia Water Protection Permit Regulation, provided that the permittee abides by the §401 Water Quality Certification condition, below, and all of the terms and conditions of 18-RP-02.

§401 Water Quality Certification Condition: For activities #2 (New Dredging) and #3 (Discharges of Dredged Material into Waters of the U.S. associated with Maintenance or New Dredging):

a) Dredging shall not be used to create a deep space for water withdrawal.

b) Any compensatory mitigation shall meet the requirements in the Code of Virginia, Section 62. 1-44. 15:23 A through C, except in the absence of same river watershed alternatives in Hydrologic Unit Codes (HUC) 02040303 and 02040304, single family dwellings or locality projects may use compensatory mitigation in HUC 02080102, 02080108, 02080110, or 02080111 in Virginia.

3. Those activities on the Potomac River extending channelward of the mean low water line may require authorization by the Virginia Marine Resources Commission (VMRC) and/or the Maryland Department of Natural Resources.

4. Authorization may also be needed from the Tennessee Valley Authority for projects constructed on the Clinch and Holston Rivers.

5. Pursuant to the Coastal Zone Management Act (CZMA) of 1972, the Virginia Department of the Environmental Quality, Virginia Coastal Zone Management Program completed its review of the Federal Consistency Determination and issued its conditional concurrence on August 16, 2018. Specifically, DEQ concurs that the RPs and General Conditions are consistent to the maximum

18-RP-02 4

extent practicable with the Virginia CZM Program provided that the following conditions are satisfied:

a) Prior to construction, applicants shall obtain all required permits and approvals for the activities to be performed that are applicable to the enforceable policies and that applicants adhere to all conditions contained therein.

b) The activities that qualify for the RPs meet the requirements of DEQ’s Virginia Water Protection Permit Regulation and the permittee abides by the conditions of the RP as certified under Section 401 of the Clean Water Act.

6. Permittees should ensure that their projects are designed and constructed in a manner consistent with all state and local requirements pursuant to the Chesapeake Bay Preservation Act and the Chesapeake Bay Preservation Area Designation and Management Regulations.

7. Authorizations under this RP do not supersede state or local government authority or responsibilities pursuant to the Chesapeake Bay Preservation Act, the Virginia Tidal Wetlands Act or to any State or local laws or regulations.

IV. PROCEDURES:

1. Prospective permittees must submit a pre-construction notification (PCN) in accordance with the procedures outlined below and must receive written authorization from the Corps before any work may begin. This RP shall not be interpreted as authorizing any work other than which is outlined above and which strictly meet all terms and conditions set out herein. All work undertaken that does not strictly comply with the following terms, conditions, standards and limitations will require separate Department of the Army authorization.

2. Within Virginia, the U.S. Army Corps of Engineers, Norfolk District encourages prospective permittees to utilize the Joint Permit Application (JPA) as the pre-construction notification. The JPA is also used to apply for corresponding permits from the Virginia Marine Resources Commission, the Virginia Department of Environmental Quality, and/or Local Wetlands Boards. The JPA process and JPA forms are used by the Corps, the VMRC, the DEQ, and the LWB for permitting purposes involving tidal and/or non-tidal water, tidal and/or non-tidal wetlands, and/or dune/beach resources, including, but not limited to, construction, dredging, filling, or excavation. Prospective permittees should read the directions on the application carefully to determine how many copies must be submitted to the VMRC, who acts as the clearinghouse for permit applications. Prospective permittees may obtain paper copies of the Joint Permit Applications by calling the Corps at (757) 201-7652, or by downloading and using one of the two versions of the JPA on the Norfolk District Regulatory Webpage:

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

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

18-RP-02 5

3. The following additional information must be included in the PCN and/or on the drawings in order for the PCN to be considered complete:

a. The distance of toe of channel from the channelward edge of mudflats and vegetated wetlands.

b. The buffer distance (buffer distance = depth of dredging x 4) between the toe of the channel and the wetlands as determined by using the “4X buffer” guidance developed by the Virginia Institute of Marine Science (VIMS) in the Virginia Wetlands Report No. 93-8, entitled “Mid-Atlantic Wetland Compensatory Mitigation Workshop,” pages 7, dated Summer 1993.

c. Existing bathymetric depth profile (i.e. depth soundings) referenced to local tidal or geodetic datum.

d. Information on the dredged material management (dredge disposal) site including location maps, drawings, and a description of the methods of transporting the material to the dredged material management site.

e. Any structures (i.e. piers, boat lifts) required to provide access to the proposed dredging. (Note: Piers and related structures are not authorized by this permit, but may be authorized under other general permits.)

f. For maintenance dredging projects, a cover letter describing the proposed dredging activity and a copy of any previous Department of the Army permit(s) must be submitted in order to initiate the permit evaluation for the proposed maintenance project.

4. On a case-by-case evaluation, the Corps may determine that a “Tier 1” or additional testing of the sediment to be dredged is required to evaluate the potential for contaminants. If testing is required, a sampling and analysis plan shall be submitted to the Norfolk District for approval. Testing results must be submitted to, and approved by, the Norfolk District prior to dredging. The evaluation of dredged material for inland disposal will follow the guidance in the “Evaluation of Dredged Material Proposed for Discharge in Waters of the U.S. - Testing Manual (Inland Testing Manual), dated February, 1998, or the most current version. The manual may be downloaded from the Environmental Protection Agency website:

http://water.epa.gov/type/oceb/oceandumping/dredgedmaterial/testing.cfm.

In order to protect vegetated wetlands, a buffer distance of four times the depth of dredging, i.e. “4X Buffer”, must be maintained between the toe of the dredged channel and the channelward edge of the vegetated wetlands. The buffer distance is to be determined by using the guidance developed by Virginia Institute of Marine Science (VIMS) in the Virginia Wetlands Report No. 93-8, entitled “Mid-Atlantic Wetland Compensatory Mitigation Workshop,” pages 7, dated Summer 1993, which explains how to properly obtain the “4X Buffer” distance. This report can be found at the following website:

18-RP-02 6

2. Corps authorization of the dredging is to a certain depth at mean low water and/or ordinary high water, referenced to local tidal or geodetic datum, as outlined on drawings provided by the prospective permittee with the pre-construction notification. The Corps-approved permitted depth includes any advance maintenance, allowable over depth, and/or margin of error. Exceeding this depth will be considered a violation of the terms and conditions of this permit. The Permittee is responsible for compliance with the terms and conditions of this RP, regardless of who performs the work. The Permittee shall ensure contractors and/or workers have knowledge of the terms and conditions of the RP. The only way to legally dredge deeper is to apply for, and be granted, a new permit verification before the dredging occurs. If the requested modifications exceed the terms and conditions of this RP then an Individual Department of the Army permit will be required.

3. Periodic maintenance dredging may be performed until expiration of this regional permit authorization. Each maintenance dredging event is limited to the removal of material at a depth no deeper than the current authorized dredge depth.

Following the initial dredging event, the permittee must contact the Corps, in writing, a minimum of two weeks in advance of each subsequent maintenance dredging activity. Maintenance dredging must use the same dredged material disposal site as authorized under this current RP authorization; if a new disposal site is necessary, a written permit verification is required from the Corps prior to maintenance dredging.

4. All piers, associated structures (e.g., boatlifts, mooring piles, etc.) and vessels, whether existing or proposed under a different permit, will be located outside the channel.

5. Any authorized dredging located adjacent to certain resources (including shellfish beds, submerged aquatic vegetation, and anadromous fish use areas) will require a time of year restriction (TOYR), unless determined unnecessary through additional agency coordination. The TOYR indicates the time of any given year that the authorized dredging cannot be performed in order to protect these resources. The TOYR for these resources are as follows:

• Shellfish beds: March 1 through September 30

• Submerged Aquatic Vegetation: March 1 through October 31

• Anadromous Fish Use Areas: February 15 through June 30

6. All dredged material must be disposed of in an approved dredged material disposal site, in an approved upland disposal site, or at the Craney Island Dredged Material Management Area/Rehandling Basin. The disposal of dredged material into waters of the U.S. (including wetlands) is not authorized by this permit, except at approved dredged material disposal sites. Currently approved dredged material management sites do not include ocean disposal sites; use of ocean disposal must be permitted under separate authorization.

18-RP-02 7

7. If an upland disposal site is to be utilized, the site must be properly designed to contain the material and have proper erosion and sedimentation controls to prevent overtopping and re-entry into the waterway. In addition, the prospective permittee must adequately address the need for liner or impermeable material to prevent leaching of any identified contaminants into ground water.

8. Craney Island Dredged Material Management Area (CIDMMA) and Craney

Island Rehandling Basin (CIRB):

a. The prospective permittee may request to use CIDMMA and/or CIRB, and the Corps will consider the request in accordance with the PL3 and District policy;

requirements include specification that work must be related to the development or maintenance of navigation improvements in the Norfolk Harbor and adjacent channels. You must receive specific approval in your permit in order to dispose of dredged material at CIDMMA and/or CIRB.

b. The dredged material will be transported by barge to CIRB or by pipeline to the CIDMMA. If the CIDMMA or the CIRB become unavailable for use as a dredged material placement area during the terms of this authorization, you will be responsible for finding an alternate placement area and having it approved by this office prior to any further dredging.

c. Permitted users of CIDMMA and all associated dredged material placement operations shall comply with the current version of the Army Corps of Engineers, Norfolk District, Commander’s Policy Memorandum Number WRD-01, "Deposition of Dredged Material and use of the Craney Island Dredged Material Management Area, Norfolk Harbor, Virginia".

d. The form titled "Deposit of Material into Craney Island" must be completed prior to depositing material into the CIDMMA or Rehandling Basin. Please be advised that it is the permittee’s responsibility to ensure that the Corps receives the appropriate payments. Contact our Operations Support Section at (757) 201-7642 or (757) 201-7017 or the Craney Island Project Office at

(757) 484-1021 to obtain current conditions and toll rates at CIDMMA.

e. The permittee is hereby advised that the prime contractor performing the dredging project must obtain a Real Estate license from the Norfolk District Real Estate Office prior to the commencement of any work which would utilize the Craney Island Dredged Material Management Area or Government Bulkhead Facilities at the Craney Island Rehandling Basin. The permittee/prime contractor should contact the Norfolk District Real Estate Acquisition, Management, and Disposal Section at (757) 201-7730 for further information regarding the Department of the Army License.

9. Within 30 days of completion of the dredging, an after-dredge hydrographic survey, prepared by a state-certified engineer or surveyor, must be provided to

3 Refer to H.D. 563, 79th Congress, 2nd Session, P.L. 79-525

18-RP-02 8

the Corps. The hydrographic survey should reference a local tidal or geodetic datum.

10. Barges and scows used to transport dredged material may be filled only to a point where no overflow occurs. No overflow pipes are allowed.

VI. GENERAL CONDITIONS:

1. Navigation:

a. No activity may cause more than a minimal adverse effect on navigation.

b. Any safety lights and signals prescribed by the U.S. Coast Guard, through regulations or otherwise, must be installed and maintained at the permittee’s expense on authorized facilities in navigable waters of the U.S. The U.S.

Coast Guard may be contacted at the following address: Commander (oan), Fifth Coast Guard District, Federal Building, 431 Crawford Street, Portsmouth, Virginia 23704 or by telephone: (757) 398-6230.

c. The permittee understands and agrees that if future operations by the United

States require the removal, relocation, or other alteration of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his/her authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from the Corps, to remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United States. No claim shall be made against the United States on account of any such removal or alteration.

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 which normally migrate through the area, unless the activity’s primary purpose is to impound water. All permanent and temporary crossings 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 U.S. that serve as breeding areas for migratory birds must be avoided to the maximum extent practicable.

18-RP-02 9

5. Shellfish Beds: No activity may occur in areas of concentrated shellfish populations.

6. Submerged Aquatic Vegetation (SAV) Beds: Activities in SAV beds must be avoided and minimized to the maximum extent practicable. Avoidance and minimization measures, such as relocating a structure and/or the implementation of a time-of-year restriction for work in waters, may be required to reduce impacts to the SAV habitat. Information regarding SAV may be found at the Virginia Institute of Marine Science’s website at: http://web.vims.edu/bio/sav/.

7. Suitable 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).

8. Water Supply Intakes: No activity may occur in the proximity of a public water supply intake, except where the activity is for the repair or improvement of public waters supply intake structures or adjacent bank stabilization.

9. Adverse Effects from Impoundments: If the activity creates an impoundment of water, adverse effects to the aquatic system due to accelerating…
