MODIFICATION OF GENERAL PERMIT 2011-001 FOR
MAINTENANCE CLEARING OF RIVERS, STREAMS, STORM DRAINS
AND BEACH AREAS IN THE STATE OF HAWAII

1. Interested parties are hereby notified that, under authority of Section 10 of the Rivers and Harbors Act of 1899, a general permit authorizing maintenance clearing of rivers, streams, storm drains, and beach areas in water of the United States, including navigable waters in the State of Hawaii was modified and re-issued to the general public, groups, and agencies, effective this date. This permit is not issued under authority of Section 404 of the Clean Water Act as it does not authorize any sidecasting of the removed materials, any discharge of dredged or fill material, nor any return water from authorized work into a water of the U.S.

2. A copy of the modified general permit is attached. Please note the changes to excluded areas and the limitations and conditions on work to be authorized by GP 2011-001. This modified general permit became effective on April 13, 2012 and expires in five years on April 13, 2017.

3. The Corps received a concurrence with our Coastal Zone Management (CZM) program consistency determination covering projects authorized by GP 2011-001on January 3, 2011, reserving the right to require individual federal consistency reviews whenever CZM determines that an activity may adversely affect coastal resources or uses. This requires the applicant to provide the CZM Program a copy of their notification per Condition No. 9 of the attached permit. The general permit does change any conditions and requirements required by the initial CZM consistency determination.

            d. Special Conditions:

                        The following special conditions apply to all activities authorized under this general permit:

                        (1) The permittee should make every effort to develop and implement a plan spanning the length of this general permit which schedules conducting anticipated work at streams and storm-drains during the dry season, and anticipated work at beach areas during nonswell season. Work should be ceased and re-scheduled in the event of an out-of-season heavy rainfall or swell;

                        (2) Use of bulldozers to remove sediments may be allowed when the permittee provides documentation that the sediment is unvegetated, or otherwise void of vegetal root systems and that equipment-specific best management practices (BMPs) shall be in place to avoid more than de minimis discharges to waters of the United States;

                        (3) Avoid conducting maintenance activities that will lead to mid- and long-term destabilization and exposure of bare sediment/sand along stream banks, stream bed and beaches;

                        (4) Prior to starting any authorized activity, determine via surveys or available literature whether coral reef and/or seagrass beds are present near, or downstream of, areas where the activities will be conducted. Where coral reef or seagrass could be indirectly impacted by the authorized work, the permittee must minimize any potential impacts by limiting the extent of inwater work by conducting the work from land, limiting the footprint of the work/dredge area, and implementing appropriate BMPs;

                        (5) No debris, petroleum projects, or deleterious materials or wastes shall be allowed to fall, flow, leach, or otherwise enter any waters of the United States;

                        (6) All authorized activities shall be done in a manner so as to confine and isolate the construction activity and to control and minimize turbidity. Silt curtains or other appropriate and effective silt containment devices approved by the Corps shall be used to minimize turbidity and shall be properly maintained throughout the entire period of in-water work to prevent the discharge of any material to the downstream aquatic habitat. All sediment control devices installed as BMPs (i.e., fabric sandbags, silt curtains/screens, etc.) downstream or makai of the authorized work shall remain in place until the in-water work is completed and will be removed in their entirety and disposed of at an appropriate upland location once the water quality of the affected area has returned to its pre-construction condition;

                        (7) Return flow or runoff from upland dewatering site(s)/disposal site(s) shall be contained on land and shall not be allowed to discharge and/or re-enter any waters of the United States;

                        (8) No sidecasting or stockpiling of excavated materials in the aquatic environment is authorized. All excavated materials shall be placed above the high tide line (in coastal areas), above the ordinary high water mark at all other waters of the United States, or disposed of in an upland location. The permittee shall demonstrate that there is no reasonable expectation that disposal locations adjacent to high tide lines on the ocean, or in floodplains adjacent to other rivers or streams, would result in the material being eroded into the nearby waterbody by high tides and/or flood events;

                        (9) Warning signs shall be properly deployed and maintained until the portion of the in-water work is completed and the affected area water quality has returned to its preconstruction condition and turbidity control devices have been removed from the waterway;

                        (10) Fueling, repair, and other activities with any potential to release pollutants will occur in a location where there is no potential for spills to have an effect on waters of the United States;

                        (11) If a visible plume and/or floating petroleum products are observed outside of the containment area, the following measures shall be taken:

                                    (a) All in-water work shall stop;

                                    (b) The permittee or contractor shall inform the Corps immediately and the Corps will consult with appropriate agencies;

                                    (c) The site shall be inspected by the permittee to ascertain the source of the plume;

                                    (d) Control measures shall be refurbished, modified, and/or improved, e.g., additional silt containment devices will be installed, as necessary to ensure the integrity of the containment area;

                                    (e) Work shall not continue until after the plume or oil sheen is no longer visible.

                        (12) An individual, designated responsible for environmental monitoring, will be on-site during clearing operations. This individual will conduct visual inspections, perform water quality sampling and other environmental monitoring, as appropriate, and report all results to the Corps on a regular basis during clearing operations;

                        (13) When the Corps is notified that an authorized activity is detrimental to fish and wildlife resources, the Corps will issue a suspension order until all pertinent issues have been satisfactorily resolved. The permittee shall comply with any Corps-directed remedial measures deemed necessary to mitigate or eliminate the adverse effect;

                        (14) Unless terminated earlier, the expiration date of this general permit will be five years from the date of issuance. At that time, there will be a re-evaluation and review of the environmental effects of the activities authorized under the general permit. The re-evaluation will incorporate the views of federal, state, and local agencies and the public following issuance of a new public notice. This general permit may be reissued, revised, or revoked, as appropriate. Individual projects authorized under this permit, but not completed prior to the expiration date of the general permit, may proceed in accordance with the terms and conditions of this permit, regardless of the outcome of the re-evaluation and review.

Endangered Species Act Special Conditions

                        (1) For non-Federal applicants the PCN must include the name(s) of those endangered or threatened species that might be affected by the proposed work or utilize the designated critical habitat that may be affected by the proposed work.
