They also use the cart paths west of the creek (where gravel will be placed). The Contractor shall give golf course users right-of-way on the bridge and cart paths when accessing the project site, hauling sediments from the site, and transporting and placing gravel. Major Golf Course Event Days are listed below. The Contractor should anticipate heavier traffic and possible congestion on the golf course roads on those days. Some work on the golf course may be restricted; see bid items for any specific restrictions. Mon. Tues. Weds. Thurs. Fri. Sat., Sun , August 6 7 8 10 No work 24 on weekends Sept. 3 7 The Contractor shall plan the work such that construction is completed by no later than September 15, 2007 to satisfy the HPA permit.

Bid Item 2 Construct Bypass Structures, Divert Creek, Rescue Fish, and Drain Sediment Basin (LS) This items includes all work needed for construction of temporary bypass structures, diversion of Maplewood Creek from the work areas, draining the sediment basin, and coordination with adjacent private property owner regarding water supply into a private fish pond. See the description and photos of 1999 cleaning for an example of the work and techniques needed. Water Projects CIP\27-2057 Maplewood Sed Basin\05-2007 Pond H:\File Sys\SW'P Surface Water Projects\SWP-27 Surface � ( ) p Cleaning\11 l0a Final Specs-2006 Spec\24-Bid Section1-09-14.doc Page 2 t Duringall work approximately 3/4 of the flow shall be kept moving downstream so the creek PP Y P 9 is not dewatered and fish life is not lost. Upstream Bypass Structure and Creek Diversion The upstream bypass structure will be constructed upstream of the sediment basin, next to the 18-inch bypass inlet. The bypass structure will divert the entire flow from the creek into the 18-inch bypass pipe to prevent water from flowing to the sediment basin. The bypass ' structure will be at least as high as the top of the bypass pipe, plus 3 inches. One type of material that may be used for the bypass structure is sandbags (or media bags) and plastic sheeting, keyed into the creek bed to limit potential underflow. Dirt fill shall not be used to construct the bypass structure. Water shall be kept flowing to the fish channel on the golf 1 course at all times. It will be necessary to dig a sump downstream of the bypass structure and install a sump pump to collect any water running under the bypass structure and redirect it back into the bypass pipe. Pumping will be required 24-hours a day to keep water from flowing to the sediment basin iThe work shall be planned and executed so the temporary bypass structure will be completed early in the morning (approx. 8 to 10 am), and the remainder of the day will be used for draining the sediment basin and fish rescue. Drain Sediment Basin After the upstream bypass structure is constructed and the creek is diverted, the sediment basin may be drained using the 8-inch valves in the concrete structures. Before draining starts the Contractor will place plastic sheeting anchored by sandbags on the bottom of the basin, 5 to 6 feet out from the valves, to help reduce the amount of bottom sediment that may be stirred up and discharged through the valves. After the water is drained as low as the valves will allow, the Contractor will use a portable pump to completely dewater the sediment basin. The 8-inch underdrain may also be opened to allow the sediment to dewater. If the water from the underdrain is too silty to discharge to the creek other means may be used to dewater the sediment. The contractor shall not discharge sediment laden water to the creek. The City Project Manager may assist the Contractor with the sequence needed to operate the valves to bypass and drain the sediment basin. Fish Rescue IAll fish and other aquatic life shall be rescued from the creek, sediment basin, and fish ladder and transferred to the downstream creek per the HPA and Fisheries regulations. At a minimum the Contractor shall have the following at the site for fish rescue from the sediment basin: • three laborers dedicated for fish rescue, • four nets (approx. 6"x 8") with handles, • four buckets for capturing fish, • a portable gas pump with an intake strainer meeting Fisheries requirements ( see HPA#13 1/8" intake screen sized for a surface velocity of 0.4 fps ). HAFile Sys\SWP-Surface Water Projects\SWP-27-Surface Water Projects(CIP)\27-2057 Maplewood Sed Basin\05-2007 Pond Cleaning11 110a Final Specs-2006 Spec\24-Bid Sectionl-09-14.doc Page 3 1 shall have the equipment on site for City inspection the day before installing ' The contractor Y p Y 9 the bypass and draining the basin. If the equipment is not satisfactory, and workers are not onsite the day of the bypass, installing the bypass and draining the basin shall not proceed. Fish rescue shall start with the workers walking the creek bed and rescuing all aquatic life immediately after the bypass structure is completed and flow is directed into the 18-inch ' pipe. Fish rescue shall continue while the sediment basin is being drained. Workers shall repeatedly walk the creek bed and sediment basin and continue to capture any fish present until the basin is drained. It may be necessary to use hip waders to reach fish in the middle , of the basin. It will be difficult to wade through the silt sediment at the south end of the basin. Each bucket shall be emptied within 1 hour after the first fish is placed in it. Captured fish shall be released to the creek downstream of the flow splitter structure. Coordination with Private Property Owner The private property owner (Mr. Casey McCarthy) adjacent to Maplewood Creek operates a fishpond on his property. The Contractor will be responsible for coordinating with Mr. McCarthy to keep sediment laden water from entering his fish pond while the basin is being cleaned. The City will assist the Contractor with coordination by notifying Mr. McCarty of the work no less than 1-week prior to the anticipated start date. During the maintenance period, the Contractor will be responsible for closing the valve (located on the east side of the overflow spillway) that supplies water to the fish pond. The valve must be closed before dewatering begins to avoid discharge of any silt laden water into the fish pond. After the inlet valve is close, Mr. McCarty will be responsible for supplying water to his fish pond from the creek next to his property. He usually placed a small pump in the creek adjacent to his property. The Contractor will be responsible for not disturbing Mr. McCartys pump and notifying McCarty at least 24 hours before gravel is placed in the creek above or adjacent to his property. Flow Splitter Structure and Creek Diversion Work on the flow splitter shall not occur on the Golf Course Event Days identified in Bid Item #1. A bypass structure will be constructed at the flow splitter basin to divert the creek flow , around the accumulated gravel and sediment that will be removed from the flow splitter. The bypass structure may be constructed of sandbags and plastic sheeting, or using a different method chosen by the contractor. Regardless of the procedure chosen by the ' contractor, the diversion must allow the removal of accumulated sediment from the flow splitter basin without impacting the turbidity in the low flow channel. Water shall be kept flowing to the fish channel on the golf course at all times. When the bypass is constructed the Contractor shall be responsible for immediately rescuing any fish stranded in the bypass section before removing accumulated gravel and sediment. Payment for this item will be made at the lump sum amount bid, and considered complete compensation for all design, labor equipment and materials required to complete this item of work in accordance with the Contract Documents. Payment will be prorated as the work is HAFile Sys\SWP-Surface Water Projects\SWP-27-Surface Water Projects(CIP)\27-2057 Maplewood Sed Basin\05-2007 Pond Cleaning\1 110a Final Specs-2006 Spec\24-Bid Sectionl-09-14.doc Page 4 accomplished. Bid Item 3 Remove, Haul, and Dispose of Sediment(LS) This item includes removing the accumulated sediment from all locations (the sediment ! basin, the channel at the north end of the basin, and flow splitter), loading the material into vehicles, and hauling to a private site for disposal. All costs for excavation, loading, hauling, and disposal shall be included in the bid price. ' • Sediment in the sediment basin and upper channel shall be excavated using a smooth bucket to avoid disturbing and damaging the imported backfill layer and PVC liner. • Only singe dump trucks may be used across the bridge to the sediment basin, no truck and trailer combinations. Sediment Basin The accumulated sediment above the imported backfill layer shall be removed and disposed of offsite. The sediment basin, and channel at the north end of the basin, have a 12-inch layer of imported backfill placed above a 30 mil PVC liner. The imported backfill layer is different from the sediment and it is possible to differentiate between the two materials by sight and feel. The contractor shall use the sediment basin construction plans and as-built plans to locate the top of the 12-inch imported backfill layer. The Contractor shall hand dig test holes to confirm the location and elevation of the backfill ' layer, and PVC liner at the start of construction, and during excavation, when needed. Test holes are more likely needed at the edges of the basin where the PVC liner is close to the surface, than at the center of the basin. The locations and elevations of test holes shall be reviewed with the City prior to starting excavation, and wherever they are performed during the excavation. Upper Channel ! The accumulated sediment in the upper channel north of the sediment basin will be removed to restore the area so it is similar to the as-built plans and the post construction photos. ! The center section of the channel is approximately 8 to 12 feet wide, and has rock berms at several locations along across the bottom and along the side. In the middle of the channel sediment shall be removed to the top of the rock berms. Along the sides sediment must be carefully removed from between the rock berms without disturbing them. Some rocks may need to be adjusted or added to the berms.

Description of Authorized Activities B. Corps National General Conditions for all NWPs C. Additional Limitations on the Use of NWPs In addition to any special condition that may be required on a case-by-case basis by the District Engineer, the following terms and conditions must be met, as applicable, for a Nationwide Permit 33 authorization to be valid in Washington State. A. DESCRIPTION OF AUTHORIZED ACTIVITIES 33. Temporary Construction, Access, and Dewatering. , Temporary structures, work, and discharges, including cofferdams, necessary for construction activities or access fills or dewatering of construction sites,provided that the associated primary activity is authorized by the Corps of Engineers or the U.S. Coast Guard. This NWP also authorizes temporary structures, work, and discharges, including cofferdams, necessary for construction activities not otherwise subject to the Corps or U.S. Coast Guard permit requirements. Appropriate measures must be taken to maintain near normal downstream , flows and to minimize flooding. Fill must consist of materials, and be placed in a manner, that will not be eroded by expected high flows. The use of dredged material may be allowed if the district engineer determines that it will not cause more than minimal adverse effects on aquatic resources. Following completion of construction,temporary fill must be entirely removed to upland areas, dredged material must be returned to its original location, and the affected areas must be restored to pre-construction elevations. The affected areas must also be revegetated, as appropriate. This permit does not authorize the use of cofferdams to dewater wetlands or other aquatic areas to change their use. Structures left in place after construction is completed require a section 10 permit if located in navigable waters of the United States. (See 33 CFR part 322.) , Notification: The permittee must submit a pre-construction notification to the district engineer prior to commencing the activity (see general condition 27). The pre-construction notification must include a restoration plan showing how all temporary fills and structures will be removed and the area restored to pre-project conditions. (Sections 10 and 404) B. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPs 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 United States. (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 authorized representative,said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters,the permiee will be required,upon due notice from the Corps of Engineers,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 that normally migrate through the area, unless the activity's primary purpose is to impound water. Culverts placed in streams must be installed to maintain low flow conditions. 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. 6. 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). j7. 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 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 and storm water management activities, 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 high 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. 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. Soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used 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 line,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. 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. 2 1 14.Proper Maintenance. Any authorized structure or fill shall be properly maintained, including maintenance to , ensure public safety. 15. Wild and Scenic Rivers.No 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. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency in the area(e.g.,National Park Service,U.S. Forest Service,Bureau of Land Management,U.S. Fish and Wildlife Service). 16.Tribal Rights.No activity or its operation may impair reserved tribal rights, including,but not limited to, reserved water rights and treaty fishing and hunting rights. 17.Endangered Species.(a)No activity is authorized under any NWP which is likely to 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 which will destroy or adversely modify the critical habitat of such species.No activity is authorized under any NWP which"may affect"a listed species or critical habitat,unless Section 7 consultation addressing the effects of the proposed activity has been completed. (b)Federal agencies should follow their own procedures for complying with the requirements of the ESA. Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. (c)Non-federal permittees shall notify the district engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or if the project 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 may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work.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 the vicinity of the project,and has so notified the Corps, the applicant shall not begin work until the Corps has provided notification the proposed activities will have"no effect"on listed species or critical habitat,or until Section 7 consultation has been completed.(d)As a result of formal or informal consultation with the FWS or NMFS the district engineer may add species-specific regional endangered species conditions to the NWPs. (e) Authorization of an activity by a 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 U.S. FWS or the NMFS,both lethal and non-lethal"takes" of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the U.S.FWS and NMFS or their world wide Web pages at http://www.fws.gov/and http://www.noaa.gov/fisheries.html respectively. 18.Historic Properties. (a)In cases where the district engineer determines that the activity may affect 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.Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. (c)Non-federal permittees must submit a pre-construction notification to the district engineer if the authorized activity may have the potential to cause effects to any historic properties listed,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 may be affected by the proposed work 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 the location of or potential for the presence of historic resources can be sought from the State Historic Preservation Officer or Tribal Historic Preservation Officer,as appropriate,and the National Register of Historic Places(see 33 CFR 330.4(g)).The district engineer shall make a reasonable and good faith effort to carry 3 1 iout appropriate identification efforts,which may include background research, consultation,oral history interviews, sample field investigation,and field survey. Based on the information submitted and these efforts,the district engineer shall determine whether the proposed activity has the potential to cause an effect on the historic properties. Where the non-Federal applicant has identified historic properties which the activity may 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 or that consultation under Section 106 of the NHPA I has been completed. (d) 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. Section 106 consultation is not required when the Corps determines that the activity does not have the potential to cause effects on historic properties(see 36 CFR§800.3(a)). If NHPA section 106 consultation is required and will occur,the district engineer will notify the non-Federal applicant that he or she cannot begin work until Section 106 consultation is completed. (e) Prospective permittees should be aware that section I l0k of the NHPA(16 U.S.C. 470h-2(k))prevents the Corps from granting a permit or other assistance to an applicant who,with intent to 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(ACHP),determines that circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If circumstances justify granting the assistance,the Corps is required to notify the ACHP and provide documentation specifying the circumstances,explaining 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. 19. Designated Critical Resource Waters.Critical resource waters include,NOAA-designated marine sanctuaries,National Estuarine Research Reserves,state natural heritage sites,and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the district engineer after notice and opportunity for public comment.The district engineer may also designate additional critical resource waters after notice and opportunity for 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,and 50 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,and 38,notification is required in accordance with general condition 27, 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. 20. Mitigation.The district engineer will consider the following factors when determining appropriate and practicable mitigation necessary to ensure that adverse effects on the aquatic environment are 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 compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are 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 some other form of mitigation would be more ' environmentally appropriate and provides a project-specific waiver of this requirement.For wetland losses of 1/10 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 minimal adverse effects on the aquatic environment. Since the likelihood of success is greater and the impacts to potentially valuable uplands are reduced, wetland restoration should be the first compensatory mitigation option considered.(d)For losses of streams or other open waters that require pre-construction notification,the district engineer may require compensatory mitigation, such as stream restoration,to ensure that the activity results in minimal adverse effects on the aquatic environment. (e)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 project 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 4 necessary,to ensure that a project already meeting the established acreage limits also satisfies the minimal impact j requirement associated with the NWPs. (f)Compensatory mitigation plans for projects in or near streams or other open waters will normally include a requirement for the establishment,maintenance,and legal protection(e.g., conservation easements)of riparian areas next to open waters. In some cases,riparian areas may be the only compensatory mitigation required. 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. Where both wetlands and open waters exist on the project site, 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 compensatory mitigation,the district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland losses.(g)Permittees may propose the use of mitigation banks, in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan.(h)Where certain functions and services of waters of the United States are permanently adversely affected,such as the conversion of 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 effects of the project to the minimal level. , 21. 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. 22. 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. 23. 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. 24. 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 N WPs 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 cannot exceed 1/3-acre. 25.Transfer of Nationwide Permit Verifications.If the permittee sells the property associated 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) 5 j l 26.Compliance Certification.Each permittee who received an NWP verification from the Corps must submit a signed certification regarding the completed work and any required mitigation. The certification form must be forwarded by the Corps with the NWP verification letter and will include: (a)A statement that the authorized work was done in accordance with the NWP authorization, including any general or specific conditions;(b)A statement I that any required mitigation was completed in accordance with the permit conditions;and(c)The signature of the permittee certifying the completion of the work and mitigation. 27.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,as a general rule,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:(1)Until notified in writing by the district engineer that the activity may proceed under the NWP with any special conditions imposed by the district or division engineer;or(2)If 45 calendar days have passed from the district engineer's receipt of the complete PCN and the prospective permittee has not received written notice from the district or division engineer. However, if the permittee was required to notify the Corps pursuant to general condition 17 that listed species or critical habitat might affected or in the vicinity of the project,or to notify the Corps pursuant to general condition 18 that the activity may have the potential to cause effects to historic properties, the permittee cannot begin the activity until receiving written notification from the Corps that is"no effect"on listed species or"no potential to cause effects"on historic properties,or that any consultation required under Section 7 of 1 the Endangered Species Act(see 33 CFR 330.4(f))and/or Section 106 of the National Historic Preservation(see 33 CFR 330.4(g))is 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 cannot 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 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 right to proceed under the NWP may be modified,suspended,or revoked only in accordance with 1 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 information: (1)Name,address and telephone numbers of the prospective permittee; (2)Location of the proposed project;(3)A description of the proposed project;the project's purpose;direct and indirect adverse environmental effects the project would cause;any other NWP(s),regional general permit(s),or individual permit(s)used or intended to be used to authorize any part of the proposed project or any related activity.The description should be sufficiently detailed to allow the district engineer to determine that the adverse effects of the project will be minimal and to determine the need for compensatory mitigation. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP.(Sketches usually clarify the project and when provided result in a quicker decision.); (4)The PCN must include a delineation of special aquatic sites and other waters of the United States 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 of the United States,but there may be a delay if the Corps does the delineation,especially if the project site is large or contains many waters of the United States. Furthermore,the 45 day period will not start until the delineation has been submitted to or completed by the Corps, where appropriate;(5)If the proposed activity will result in the loss of greater than 1/10 acre of wetlands and a PCN is required,the prospective permittee must submit a statement describing how the mitigation requirement will be satisfied.As an alternative,the prospective permittee may submit I a conceptual or detailed mitigation plan. (6)If any listed species or designated critical habitat might be affected or is in the vicinity of the project,or if the project is located in designated critical habitat, 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.Federal applicants must provide documentation demonstrating compliance with the Endangered Species Act;and(7)For an activity that may affect a historic property listed on, determined to be eligible for listing on,or potentially eligible for listing on,the National Register of Historic Places, for non-Federal applicants the PCN must state which historic property may be affected by the proposed work or include a vicinity map indicating the location of the historic property. Federal 6 i applicants must provide documentation demonstrating compliance with Section 106 of the National Historic Preservation Act. (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 a PCN and must include all of the information required in paragraphs(b)(1)through(7)of this general condition.A letter containing the required information may also be used. (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 project's adverse environmental effects to a minimal level.(2)For all NWP 48 activities requiring pre-construction notification and for other NWP activities requiring pre-construction notification to the district engineer that result in the loss of greater than 1/2-acre of waters of the United States,the district engineer will immediately provide(e.g.,via facsimile transmission,overnight mail,or other expeditious manner)a copy of the PCN to the appropriate Federal or state offices(U.S. FWS,state natural resource or water quality agency,EPA, State Historic Preservation Officer(SHPO)or Tribal Historic Preservation Office(THPO),and, if appropriate,the NMFS). With the exception of NWP 37,these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the district engineer notice that they intend to provide substantive, site-specific comments. 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 comments received within the specified time frame,but 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.(3)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.(4)Applicants are encouraged to provide the Corps multiple copies of pre-construction notifications to expedite agency coordination. (5)For NWP 48 activities that require reporting,the district engineer will provide a copy of each report within 10 calendar days of receipt to the appropriate regional office of the NMFS. (e)District Engineer's Decision: 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 the proposed activity requires a PCN and will result in a loss of greater than 1/10 acre of wetlands,the prospective permittee should submit a mitigation proposal with the PCN.Applicants may also propose compensatory mitigation for projects with smaller impacts. The district engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are 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 effects on the aquatic environment are minimal,after considering mitigation,the district engineer will notify the permittee and include any conditions the district engineer deems necessary.The district engineer must approve any compensatory mitigation proposal before the permittee commences work. 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 plan within 45 calendar days of receiving a complete PCN and determine whether the proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal)are determined by the district engineer to be minimal,the district engineer will provide a timely written response to the applicant. The response will state that the project can proceed under the terms and conditions of the NWP. If the district engineer determines that the adverse effects of the proposed work are more than minimal,then the district engineer will notify the applicant either: (1)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit;(2)that the project is authorized under the NWP subject to the applicant's submission of a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level;or(3)that the project is authorized under the NWP with specific modifications or conditions. Where the district engineer determines that mitigation is required to 7 1 ensure no more than minimal adverse effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period.The authorization will include the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level. When mitigation is required,no work in waters of the United States may occur until the district engineer has approved a specific mitigation plan. 28. 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. C. ADDITIONAL LIMITATIONS ON THE USE OF NWPs 1. District Engineers have authority to determine if an activity complies with the terms and conditions of an NWP. l2. NWPs do not obviate the need to obtain other Federal,state,or local permits,approvals,or authorizations required by law. 3. NV,/Ts 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. 6. If future operations by the United States require the removal,relocation,or other alteration of the work herein authorized,or if, in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters,you will be required,upon due notice from the U. S Army Corps of Engineers,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. 8 NATIONWIDE PERMIT 27 US Army Corps of Engineers o Terms and Conditions Seattle District Effective Date: March 19, 2007 A. Description of Authorize d Activities B. Corps National General Conditions for all NWPs j C. Additional Limitations on the Use of NWPs In addition to any special condition that may be required on a case-by-case basis by the District Engineer, the following terms and conditions must be met, as applicable, for a Nationwide Permit 27 authorization to be valid in Washington State. A. DESCRIPTION OF AUTHORIZED ACTIVITIES 27.Aquatic Habitat Restoration Establishment and Enhancement Activities.Activities in waters of the United States associated with the restoration,enhancement,and establishment of tidal and non-tidal wetlands and riparian areas and the restoration and enhancement of non-tidal streams and other non-tidal open waters,provided those activities result in net increases in aquatic resource functions and services. To the extent that a Corps permit is required, activities authorized by this NWP include,but are not limited to: the removal of accumulated sediments;the installation, removal,and maintenance of small water control structures, dikes, and berms;the installation of current deflectors; the enhancement,restoration,or establishment of riffle and pool stream structure;the placement of in-stream habitat structures;modifications of the stream bed and/or banks to restore or establish stream meanders;the backfilling of artificial channels and drainage ditches;the removal of existing drainage structures;the construction of small nesting islands;the construction of open water areas;the construction of oyster habitat over unvegetated bottom in tidal waters;shellfish seeding;activities needed to reestablish vegetation,including plowing or discing for seed bed preparation and the planting of appropriate wetland species;mechanized land clearing to remove non-native invasive,exotic,or nuisance vegetation; and other related activities.Only native plant species should be planted at the site. This NWP authorizes the relocation of non-tidal waters, including non-tidal wetlands and streams,on the project site provided there are net increases in aquatic resource functions and services. ' Except for the relocation of non-tidal waters on the project site,this NWP does not authorize the conversion of a stream or natural wetlands to another aquatic habitat type(e.g.,stream to wetland or vice versa)or uplands. This ' NWP does not authorize stream channelization. This NWP does not authorize the relocation of tidal waters or the conversion of tidal waters,including tidal wetlands,to other aquatic uses,such as the conversion of tidal wetlands into open water impoundments. Reversion.For enhancement,restoration,and establishment activities conducted: (1)In accordance with the , terms and conditions of a binding wetland enhancement, restoration,or establishment agreement between the landowner and the U.S.Fish and Wildlife Service(FWS),the Natural Resources Conservation Service(NRCS),the Farm Service Agency(FSA),the National Marine Fisheries Service(NMFS),the National Ocean Service(NOS),or their designated state cooperating agencies;(2)as voluntary wetland restoration,enhancement, and establishment actions documented by the NRCS or USDA Technical Service Provider pursuant to NRCS Field Office Technical Guide standards;or(3)on reclaimed surface coal mine lands, in accordance with a Surface Mining Control and Reclamation Act permit issued by the OSM or the applicable state agency,this NWP also authorizes any future discharge of dredged or fill material associated with the reversion of the area to its documented prior condition and use(i.e.,prior to the restoration,enhancement,or establishment activities).The reversion must occur within five years after expiration of a limited term wetland restoration or establishment agreement or permit,and is authorized in these circumstances even if the discharge occurs after this NWP expires.The five-year reversion limit does not apply to agreements without time limits reached between the landowner and the FWS,NRCS, FSA,NMFS,NOS,or an appropriate state cooperating agency.This NWP also authorizes discharges of dredged or fill material in waters of the United States for the reversion of wetlands that were restored,enhanced,or established on prior-converted cropland that has not been abandoned or on uplands, in accordance with a binding agreement between the landowner and NRCS, FSA,FWS,or their designated state cooperating agencies(even though the restoration,enhancement,or establishment activity did not require a section 404 permit).The prior condition will be documented in the original agreement or permit,and the determination of return to prior conditions will be made by the Federal agency or appropriate state agency executing the agreement or permit.Before conducting any reversion activity the permittee or the appropriate Federal or state agency must notify the district engineer and include the documentation of the prior condition. Once an area has reverted to its prior physical condition, it will be subject to whatever the Corps Regulatory requirements are applicable to that type of land at the time. The requirement that the activity result in a net increase in aquatic resource functions and services does not apply to reversion activities meeting the above conditions. Except for the activities described above,this NWP does not authorize any future discharge of dredged or fill material associated with the reversion of the area to its prior condition. In such cases a separate permit would be required for any reversion. Reporting:For those activities that do not require pre-construction notification,the permittee must submit to the district engineer a copy of.(1)The binding wetland enhancement,restoration,or establishment agreement, or a project description, including project plans and location map;(2)the NRCS or USDA Technical Service Provider documentation for the voluntary wetland restoration,enhancement,or establishment action;or(3)the SMCRA permit issued by OSM or the applicable state agency. These documents must be submitted to the district engineer at least 30 days prior to commencing activities in waters of the United States authorized by this NWP. Notification.The permittee must submit a pre-construction notification to the district engineer prior to commencing the activity(see general condition 27),except for the following activities: (1)Activities conducted on non-Federal public lands and private lands, in accordance with the terms and conditions of a binding wetland enhancement,restoration,or establishment agreement between the landowner and the U.S. FWS,NRCS,FSA,NMFS,NOS,or their designated state cooperating agencies; (2)Voluntary wetland restoration,enhancement,and establishment actions documented by the NRCS or USDA Technical Service Provider pursuant to NRCS Field Office Technical Guide standards;or (3)The reclamation of surface coal mine lands, in accordance with an SMCRA permit issued by the OSM or the applicable state agency. However,the permittee must submit a copy of the appropriate documentation.(Sections 10 and 404) Note: This NWP can be used to authorize compensatory mitigation projects, including mitigation banks and in- lieu fee programs.However,this NWP does not authorize the reversion of an area used for a compensatory mitigation project to its prior condition,since compensatory mitigation is generally intended to be permanent. B. CORPS NATIONAL GENERAL CONDITIONS FOR ALL NWPs 1.Navi ation. (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 United States.(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 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 of Engineers,to remove,relocate, or alter the structural work or obstructions caused thereby,without expense to the United States.No claim shall be 2 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 that normally migrate through the area, unless the activity's primary purpose is to impound water.Culverts placed in streams must be installed to maintain low flow conditions. 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. Mi rg atory 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. 6. 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). 7. 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 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 and storm water management activities,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 high 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. 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. Soil Erosion and Sediment Controls.Appropriate soil erosion and sediment controls must be used 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 line,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. 13. Removal of Temporary Fills.Temporary fills must be removed in their entirety and the affected areas i 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. 15. Wild and Scenic Rivers.No activity may occur in a component of the National Wild and Scenic River 3 , 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. Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land management agency in the area(e.g.,National Park Service,U.S.Forest Service,Bureau of Land Management,U.S. Fish and Wildlife Service). 16.Tribal Rights.No activity or its operation may impair reserved tribal rights, including,but not limited to, reserved water rights and treaty fishing and hunting rights. 17.Endangered Species.(a)No activity is authorized under any NWP which is likely to 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 which will destroy or adversely modify the critical habitat of such species.No activity is authorized under any NWP which"may affect"a listed species or critical habitat,unless Section 7 consultation addressing the effects of the proposed activity has been completed. (b)Federal agencies should follow their own procedures for complying with the requirements of the ESA.Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. (c)Non-federal permittees shall notify the district engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the project,or if the project 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 may be affected by the proposed work or that utilize the designated critical habitat that may be affected by the proposed work. 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 the vicinity of the project,and has so notified the Corps,the applicant shall not begin work until the Corps has provided notification the proposed activities will have"no effect"on listed species or critical habitat,or until Section 7 consultation has been completed. (d)As a result of formal or informal consultation with the FWS or NMFS the district engineer may add species-specific regional endangered species conditions to the NWPs. (e)Authorization of an activity by a 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 U.S. FWS or the NMFS, both lethal and non-lethal"takes"of protected species are in violation of the ESA. Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the U.S. FWS and NMFS or their world wide Web pages at http://www.fws.gov/and http://www.noaa.gov/fisheries.html respectively. 18.Historic Properties. (a) In cases where the district engineer determines that the activity may affect 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. Federal permittees must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. (c)Non-federal permittees must submit a pre-construction notification to the district engineer if the authorized activity may have the potential to cause effects to any historic properties listed,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 may be affected by the proposed work 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 the location of or potential for the presence of historic resources can be sought from the State Historic Preservation Officer or Tribal Historic Preservation Officer,as appropriate,and the National Register of Historic Places(see 33 CFR 330.4(g)). 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 and these efforts, the district engineer shall determine whether the proposed activity has the potential to cause an effect on the historic properties. 4 Where the non-Federal applicant has identified historic properties which the activity may 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 or that consultation under Section 106 of the NHPA has been completed.(d) 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. Section 106 consultation is not required when the Corps determines that the activity does not have the potential to cause effects on historic properties(see 36 CFR§800.3(a)). If NHPA section 106 consultation is required and will occur,the district engineer will notify the non-Federal applicant that he or she cannot begin work until Section 106 consultation is completed. (e) Prospective permittees should be aware that section 110k of the NHPA(16 U.S.C.470h-2(k)) prevents the Corps from granting a permit or other assistance to an applicant who,with intent to 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(ACHP),determines that circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If circumstances justify granting the assistance,the Corps is required to notify the ACHP and provide documentation specifying the circumstances,explaining 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. 19.Desiynated Critical Resource Waters.Critical resource waters include,NOAA-designated marine i sanctuaries,National Estuarine Research Reserves,state natural heritage sites,and outstanding national resource waters or other waters officially designated by a state as having particular environmental or ecological significance and identified by the district engineer after notice and opportunity for public comment.The district engineer may also designate additional critical resource waters after notice and opportunity for 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,and 50 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,and 38,notification is required in accordance with general condition 27,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. 20. Mitigation.The district engineer will consider the following factors when determining appropriate and practicable mitigation necessary to ensure that adverse effects on the aquatic environment are 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 compensating)will be required to the extent necessary to ensure that the adverse effects to the aquatic environment are 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 some other form of mitigation would be more environmentally appropriate and provides a project-specific waiver of this requirement.For wetland losses of 1/10 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 minimal adverse effects on the aquatic environment. Since the likelihood of success is greater and the impacts to potentially valuable uplands are reduced, wetland restoration should be the first compensatory mitigation option considered.(d)For losses of streams or other open waters that require pre-construction notification,the district engineer may require compensatory mitigation, such as stream restoration,to ensure that the activity results in minimal adverse effects on the aquatic environment. (e)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 project 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 a project already meeting the established acreage limits also satisfies the minimal impact requirement associated with the NWPs.(f)Compensatory mitigation plans for projects in or near streams or other 5 ' ' open waters will normally include a requirement for the establishment,maintenance,and legal protection(e.g., conservation easements)of riparian areas next to open waters. In some cases,riparian areas may be the only compensatory mitigation required.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. Where both wetlands and open waters exist on the project site, 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 compensatory mitigation,the district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland losses.(g)Permittees may propose the use of mitigation banks, in-lieu fee arrangements or separate activity-specific compensatory mitigation. In all cases,the mitigation provisions will specify the party responsible for accomplishing and/or complying with the mitigation plan.(h)Where certain functions and services of waters of the United States are permanently adversely affected,such as the conversion of 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 effects of the project to the minimal level. 21. 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. 22. 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. 23. 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. 24. 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 cannot exceed 1/3-acre. 25. Transfer of Nationwide Permit Verifications. If the permittee sells the property associated 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) 6 26.Compliance Certification.Each permittee who received an NWP verification from the Corps must submit a signed certification regarding the completed work and any required mitigation.The certification form must be forwarded by the Corps with the NWP verification letter and will include: (a)A statement that the authorized work was done in accordance with the NWP authorization, including any general or specific conditions;(b)A statement that any required mitigation was completed in accordance with the permit conditions;and(c)The signature of the permittee certifying the completion of the work and mitigation. 27.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,as a general rule,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:(1)Until notified in writing by the district engineer that the activity may proceed under the NWP with any special conditions imposed by the district or division engineer;or(2)If 45 calendar days have passed from the district engineer's receipt of the complete PCN and the prospective permittee has not received written notice from the district or division engineer.However,if the permittee was required to notify the Corps pursuant to general condition 17 that listed species or critical habitat might affected or in the vicinity of the project,or to notify the Corps pursuant to general condition 18 that the activity may have the potential to cause effects to historic properties, the permittee cannot begin the activity until receiving written notification from the Corps that 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(see 33 CFR 330.4(g))is 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 cannot 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 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 right 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 information: (1)Name,address and telephone numbers of the prospective permittee;(2)Location of the proposed project;(3)A description of the proposed project;the project's purpose;direct and indirect adverse environmental effects the project would cause;any other NWP(s),regional general permit(s),or individual permit(s)used or intended to be used to authorize any part of the proposed project or any related activity.The description should be sufficiently detailed to allow the district engineer to determine that the adverse effects of the project will be minimal and to determine the need for compensatory mitigation. Sketches should be provided when necessary to show that the activity complies with the terms of the NWP. (Sketches usually clarify the project and when provided result in a quicker decision.);(4)The PCN must include a delineation of special aquatic sites and other waters of the United States 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 of the United States,but there may be a delay if the Corps does the delineation,especially if the project site is large or contains many waters of the United States.Furthermore,the 45 day period will not start until the delineation has been submitted to or completed by the Corps,where appropriate;(5)If the proposed activity will result in the loss of greater than 1/10 acre of wetlands and a PCN is required,the prospective permittee must submit a statement describing how the mitigation requirement will be satisfied.As an alternative,the prospective permittee may submit a conceptual or detailed mitigation plan. (6)If any listed species or designated critical habitat might be affected or is in the vicinity of the project,or if the project is located in designated critical habitat,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.Federal applicants must provide documentation demonstrating compliance with the Endangered Species Act;and(7)For an activity that may affect a historic property listed on,determined to be eligible for listing on,or potentially eligible for listing on,the National Register of Historic Places,for non-Federal applicants the PCN must state which historic property may be 7 ' affected by the proposed work or include a vicinity map indicating the location of the historic property. Federal applicants must provide documentation demonstrating compliance with Section 106 of the National Historic Preservation Act. (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 a PCN and must include all of the information required in paragraphs(b)(1)through(7)of this general condition.A letter containing the required information may also be used. (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 project's adverse environmental effects to a minimal level.(2)For all NWP 48 activities requiring pre-construction notification and for other NWP activities requiring pre-construction notification to the district engineer that result in the loss of greater than 1/2-acre of waters of the United States,the district engineer will immediately provide(e.g.,via facsimile transmission, overnight mail,or other expeditious manner)a copy of the PCN to the appropriate Federal or state offices(U.S.FWS, state natural resource or water quality agency, EPA,State Historic Preservation Officer(SHPO)or Tribal Historic Preservation Office(THPO),and, if appropriate,the NMFS). With the exception of NWP 37,these agencies will then have 10 calendar days from the date the material is transmitted to telephone or fax the district engineer notice that they intend to provide substantive,site-specific comments. 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 comments received within the specified time frame,but 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. (3) 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.(4)Applicants are encouraged to provide the Corps multiple copies of pre-construction notifications to expedite agency coordination.(5)For NWP 48 activities that require reporting,the district engineer will provide a copy of each report within 10 calendar days of receipt to the appropriate regional office of the NMFS. (e)District Engineer's Decision: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 the proposed activity requires a PCN and will result in a loss of greater than 1/10 acre of wetlands,the prospective permittee should submit a mitigation proposal with the PCN. Applicants may also propose compensatory mitigation for projects with smaller impacts.The district engineer will consider any proposed compensatory mitigation the applicant has included in the proposal in determining whether the net adverse environmental effects to the aquatic environment of the proposed work are 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 effects on the aquatic environment are minimal,after considering mitigation,the district engineer will notify the permittee and include any conditions the district engineer deems necessary.The district engineer must approve any compensatory mitigation proposal before the permittee commences work. 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 plan within 45 calendar days of receiving a complete PCN and determine whether the proposed mitigation would ensure no more than minimal adverse effects on the aquatic environment. If the net adverse effects of the project on the aquatic environment(after consideration of the compensatory mitigation proposal)are determined by the district engineer to be minimal,the district engineer will provide a timely written response to the applicant.The response will state that the project can proceed under the terms and conditions of the NWP. If the district engineer determines that the adverse effects of the proposed work are more than minimal,then the district engineer will notify the applicant either: (1)That the project does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit;(2)that the ' project is authorized under the NWP subject to the applicant's submission of a mitigation plan that would reduce the 8 adverse effects on the aquatic environment to the minimal level;or(3)that the project 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 effects occur to the aquatic environment,the activity will be authorized within the 45-day PCN period.The authorization will include the necessary conceptual or specific mitigation or a requirement that the applicant submit a mitigation plan that would reduce the adverse effects on the aquatic environment to the minimal level. When mitigation is required,no work in waters of the United States may occur until the district engineer has approved a specific mitigation plan. ' 28. 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. ' C. ADDITIONAL LIMITATIONS ON THE USE OF NWPs 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. 6. If future operations by the United States require the removal,relocation,or other alteration of the work herein authorized,or if,in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters,you ' will be required,upon due notice from the U. S Army Corps of Engineers,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. 9 ' Specific and General Implementation iUS Army Corps Conditions for Engineers ,Se Nearshore Fill Seattle District ' Version: May 30, 2001 ' Location: This informal programmatic consultation applies to proposed actions in Washington State where the National Marine Fisheries Service and U.S. Fish and Wildlife Service have concurred that the project not likely to adversely affect listed fish species and designated critical ' habitat and will not jeopardize proposed fish species or destroy or adversely modify proposed critical habitat.

I. General Conditions: 1. Notification. Applicants and permittees must notify the Corps via Programmatic Endangered Species Act (ESA) Consultation Specific Project Information Form for all actions proposed or completed under this programmatic consultation. If the notification is ' accomplished prior to completing the work, applicants must complete the Programmatic ESA Consultation Specific Project Information Form form and submit it with their JARPA or pre- construction notification package. , 2. Agency Access. Permittee must provide access to the work site to representatives of the Corps, National Marine Fisheries Service (NMFS), U.S. Fish and Wildlife Service (USFWS), ' Washington Department of Ecology (Ecology), and Washington Department of Fish and Wildlife (WDFW) during all hours of construction or operation. ' 3. Suitable Material. Only clean, suitable material shall be used as dredged or fill material (e.g., no trash, debris, car bodies, asphalt, etc.,). Material must be free from toxic pollutants ' in toxic amounts. 4. Removal of Temporary Fills. Any temporary fills must be removed in their entirety and the affected areas returned to their preexisting elevation and contours. 2 r 5. No work in a Superfund or Model Toxic Clean up Site. No work shall occur in or adjacent to an existing or previously designated Superf ind Clean-up site by the U.S. ' Environmental Protection Agency (EPA), or a site currently or previously designated for clean up under the Washington State Model Toxic Control Act (173-340 WAC), except for projects meeting conditions of Nationwide Permit 20. II. In-water Work Conditions: 1. In-Water Work Period. Where specified, all in-water work shall occur within the approved work window as outlined in the Programmatic Consultation—Phase I: Approved Work Windows. Allowable in-water work periods are subject to revision as new information on ESA listed or proposed fish use is obtained. 2. In-Stream Work Prohibited. Work shall be done from the top of the bank. Operation of heavy equipment directly in the active flowing channel is not covered by this consultation. 3. Restrictions on Heavy Equipment. Permittee shall use equipment having the least impact. ' Hand labor rather than heavy equipment will be used when possible and as required for individual actions under this informal programmatic consultation. Heavy equipment working in wetlands must be placed on mats, or other temporary structures to minimize soil ' disturbance and compaction. If gravel is used, the gravel must be placed on a mat and the gravel and mat removed in their entirety immediately after completion of construction. ' 4. No Disturbance to Woody Riparian Vegetation. Woody riparian vegetation shall not be disturbed or removed within 300 feet landward of the ordinary high water mark(OHW) of the stream, lake or the line of mean higher high water (MHHW) of the marine/estuarine area. 1 5. No Dumping. Material shall be carefully laced, not dumped, into the stream, lake or Yp P ' marine/estuarine area. 6. Discharges in Special Areas. Discharges into or adjacent to fish spawning area or areas ' with submerged vegetation are not authorized. 7. No Herbicides Use. No herbicides, pesticides, fertilizers, or other toxic substances are to be applied within 300 feet of a stream, lake or marine/estuarine area. III. Erosion Control and Water Quality Monitoring: Permittees must ensure they take all ' practicable steps to control erosion during construction, and establish permanent erosion protection upon completion of the work, or during extended work stoppages. 1. Erosion Control. Erosion and siltation controls (such as hydro seeding, filter bags, silt fences, grass and rock-lined swales, check dams, sediment traps, truck wheel wash, soil coverings (bonded fiber matrix), organic or fabric soil detention systems, leave strips, berms, temporary sediment basins, etc.) must be used and maintained in effective operating condition during construction to protect all exposed soil, stock piles and fills from erosion. Permittees are expected to implement the following erosion control measures as appropriate: ' 3 a. Stabilize exposed ground. All exposed ground surfaces are stabilized prior to the closure ' of the approved work window and/or within one week of project completion,whichever occurs first. Rock check dams will be used, although sterile straw bales may be used as ' an adjunct. b. Stockpiling to minimize erosion. Stockpiles shall be constructed in a manner that ' minimizes erosion, and is permanently stabilized at the earliest practicable date. Material will be stockpiled to reduce erosion by preventing runoff from the top of the stockpile from flowing down the stockpile face. Stockpiles shall be sloped away from the side facing the waterbody or wetland at all times (i.e. placing fill in tiers). Stockpiles shall be stabilized by hydroseeding (for long-term stockpiles)or covered with visqueen or other appropriate material for short-term erosion control of the stockpile. ' c. No stockpiling in a wetland or the waterbody. No stockpiling shall occur in a wetland, riparian zone, or waterward of the OHW in any stream or lake, or MHHW in any ' marine/estuarine area. d. Excess material stockpiled in uplands. All excess dredged or excavated material shall be ' placed in an upland location. e. Temporary erosion control. Permittee shall install and maintain temporary erosion ' control and ensure that erosion control measures are inspected on a regular basis during the life of the construction. f. Use non-persistent and non-invasive plants. If plants are utilized for temporary erosion ' control, species selected shall be non-persistent and non-invasive. Sterile straw or hay bales shall be used to prevent introduction of weeds. Native vegetation will be planted on , disturbed sites (including project site, disposal and staging areas, and access roads) when necessary to reduce soil erosion, establish cover, prevent invasive plant colonization, and provide shade. ' g. Stabilize and restore temporary upland access areas. Any temporary access areas will be built to avoid impacts to fish, wildlife, wetlands, or other sensitive resources. , Construction of access roads and associated staging areas shall be protected with appropriate matting, i.e. sheet piling or geo-textile fabric placed under a gravel blanket or ' other suitable material. Any temporary roads or staging areas and associated matting constructed for the project will be removed and the area restored to pre-existing or enhanced conditions upon project completion. , h. Use existing access areas. Where specified, existing upland access areas will be used to access the beach or stream areas. , i. Sedimentation ponds. Sedimentation ponds, sump ponds, swales,pumps, and any supplemental treatment facilities (may include chemical batch treatment cells, high- ' volume mechanical filtering devices, with or without chemical treatment, flow-through clarifiers, with or without chemical treatment, flow-through ponds, with chemical treatment) necessary for a particular project must be constructed and operational prior to ' 4 ' ' fill placement. The facilities will be designed to accommodate the runoff flow that can be expected depending on the time of the year project construction will take place. ' j. Wet season construction. If construction occurs during 1 November through 30 April of any year, only fill material containing less than 5 percent of very fine ' particles (such as silts, clays or the like) will be placed in the project area to reduce the amount of sedimentation generated in the construction stormwater runoff. ' k. Stormwater treatment. Stormwater collected in temporary sedimentation basins must be treated before release into any waterbody or wetland and monitored for pH, turbidity, and settleable solids, as well as bioassays to assess treated water toxicity. 1. Pumping of stormwater. Pumping of stormwater runoff to sedimentation ponds will be used when such a procedure can minimize impacts and/or allow flexibility in locating ' sedimentation ponds. in. Construction runoff. During construction, runoff from undisturbed areas will be routed ' around disturbed areas. This will reduce runoff quantities from exposed surfaces to further assure water quality standards are met. Diversion will be accomplished using diversion swales and/or temporary piping around construction areas. Pipe outlets, level spreaders, swales, or other devices may be used to reduce erosion at the discharges of these diverted clean water flows. ' n. Stormwater management maintenance. The stormwater management facilities will be regularly maintained throughout the life of the project. Maintenance may include soil and turf repair as necessary, removal of sediment accumulation from the swales and ponds, and restoration of silt fencing, pipe outlets, and outfalls. ' 2. Water Quality Limited Streams. Before beginning work on Water Quality Limited streams with limits on toxic substances, metals or organic chemicals, the permittee shall coordinate with the Washington State Department of Ecology (Ecology) to develop a ' sediment-testing plan. The plan shall include the proper testing protocol and reporting requirements. The results shall be submitted to Ecology, and permittee must receive Ecology approval before beginning work. The Washington State Water Quality Standards (WAC ' 173-201A) requires that runoff from construction projects not increase receiving stream turbidity by more than 5 NTU (Nephelometric Turbidity Units). ' IV. Spill Prevention and Control: Petroleum products, chemicals, fresh cement, construction, or deleterious materials shall not be allowed to enter waters (streams, lakes, or marine/estuarine areas) or wetlands. Permittees shall take the following precautions: 1. No fuel storage in or adjacent to waterbody. Areas for fuel storage, and refueling and servicing of construction equipment and vehicles, shall be located a minimum of 300 feet ' landward from the edge of any water body or wetlands. 2. No uncured concrete. No uncured concrete shall be placed in any water body. Where ' specified in this informal programmatic consultation, concrete must be cured before it comes into contact with the waterbody. ' 5 3. Use Biodegradable' Hydraulic Fluids. Hydraulic fluids for machinery used for in-water r work should be biodegradable in case of accidental loss of fluid. 4. Use Clean Equipment and no "washout" of equipment in or adjacent to a waterbody. ' All equipment that is used for in-water work shall be cleaned to remove external oil, grease, dirt and mud prior to placing the equipment in the water. Wash sites shall be placed so that ' wash water does not flow into the water body or a wetland without adequate treatment, no sediment will enter the waterbody or wetland, and it is located at a minimum of 300 feet landward from the edge of any waterbody or wetland. ' 5. Report Accidental Spills to Ecology. In the event of a spill, permittee shall stop work immediately and notify the Washington State Department of Ecology (Ecology). For ' Northwest Washington, contact Ecology's Northwest Regional Spill Response Office at (425) 649-7000. For Southwest Washington, contact Ecology's Southwest Regional Spill Response Office at (360) 407-6300. For Central Washington, contact Ecology's Central , Regional Spill Response Office at (509) 575-2490. For Eastern Washington, contact Ecology's Eastern Regional Spill Response Office at (509) 456-2926. In addition, for Endangered Species Act purposes, accidental spills must also be reported immediately , (within one business day) to the Corps at (206) 764-3495, NMFS at (360) 753-9530, and USFWS at (360) 753-9467. V. Minimization and Revegetation Guidelines: 1. Minimization. All projects and associated construction activities must be designed so that ' impacts to waters of the U.S., wetlands, and habitat for listed or proposed fish species are avoided and minimized to the full extent practicable. 2. Natural Beach/Stream Complexity Features. Boulder, rock, and wood debris material , P t3' Y must not be removed from any stream or shoreline area. ' 3. Revegetation Guidelines. Upon completion of work covered in this informal programmatic consultation, all disturbed herbaceous areas of the site shall be replanted with native , herbaceous and/or woody vegetation. Herbaceous plantings shall occur within 48 hours of the completion of construction. Woody vegetation components shall be planted to the Fall or early Winter, whichever occurs first. The applicant shall take appropriate measures to ensure ' revegetation success. a. Planting Plan. A planting plan must be submitted to the Corps for approval, including , species names of all plants proposed and method of planting (i.e. hydroseeding, density of cuttings, etc.). i According to established ASTM(American Society of Testing Material) procedures the following is the definition of biodegradability: A minimum of 40% of the original sample has been decomposed to inert ' ingredients within twenty-eight(28)days. 6 , b. As-built Drawings. "As-built" drawings and photographs of the planted areas or a status report must be submitted to the U.S. Army Corps of Engineers, Seattle District, ' Regulatory Branch (the Corps) and USFWS within 13 months of the date of permit issuance. ' c. Submittal of Monitoring Reports. Two monitoring reports with photographs must be submitted to the Corps and USFWS: the first monitoring report one year after the Corps written approval of the "as-built" drawings and a final monitoring report three ' years after the Corps written approval of the "as-built" drawings. Monitoring reports must include information on the percent of plants replaced, by species. Monitoring reports should state what caused plant failure. d. Performance Standard - Year 1. At the end of"Year 1" (Year 0 being the year of "as-builts"), planted species must have a survival rate of 100%, and be considered ' viable and healthy. Replanting shall be done as necessary to meet the 100% performance standard. ' e. Final Performance Standard—Year 3. At the end of"Year 3", planted species must have a survival rate of 80% and be considered viable and healthy. Eighty percent (80%) of the herbaceous revegetated area must be covered with native planted species ' or native recruit species. f. Contingency Plan. If the percent survival and cover of planted species (herbaceous ' and woody as outlined in the planting plan) does not achieve success (guidelines d and e), then remedial measures (e.g. replanting, soil amendments, or additional monitoring) may be required until the Corps and USFWS have determined that ' success has been achieved. g. Non-native, invasive plant control. The presence of non-native, invasive plant species shall not exceed 10% coverage of the revegetated area during the three-year monitoring period. A list of non-native, invasive wetland plant species for Western ' Washington is provided in Table 1. h. Preservation. During and after the three-year monitoring period, any planted woody ' vegetation within the revegetated areas shall not be removed, cut, or otherwise disturbed unless specifically approved, in writing, by the Corps.

The following The sed g notes and attached figures and photos are for future reference when the basin needs cleaning again. r Time Needed 9/20 Monday Mobilized to site - 4 to 6 hrs 9/21 Tuesday Setup, organize, try to build first bypass dam (not successful) - 8 hr 9/22 Wednesday Build bypass dam 2 to 4 hr (with material from previous day). ' Drain basin and Rescue fish - 4 to 5 hrs. 9/23 Thursday Start removing sediment, stockpile to dewater- 8 hrs 9/24 Friday Removing sediment, haul to dispose on golf course - 8 hrs 9/25 Saturday Removing sediment, haul to dispose on golf course - 8 hrs 9/27 Monday Finish removing sediment, place rocks in upper creek, start refilling basin over night - 8 hrs 9/28 Tuesday Place rocks in upper creek, remove bypass dam, drain and close bypass pipe, general raking. - 8 hrs 9/29 Wednesday General clean up and demobilize - 8 hrs (est.) I Cleaning takes about 2 weeks. Allow more time for the silty sediment to dry out. 1 r r Cost Because we the proposed lump sum prices from the fish channel contractor (we already had a contract with) seemed too high we decided to use T & M for the work. It cost about $3,200 per day (full working day, excavator, loader, dump truck, including 8.6% tax). Disposal cost was minimal because the golf course took all the material for landscaping and future course revisions. r The cost for hauling off site was estimated at $10 per cy for the truck and driver, plus $4 per cy for dry soil or $8 per cy for wet soil. The material could have gone to a soil site near Cedar Hills landfill, about a 2 '/z hour round trip. Observations and Lessons Learned McCarty Trout Pond Be sure the adjacent property owner with the fish pond (Casey McCarty) is notified at least one week before the work starts. He will have to get a pump and place it in the creek adjacent his property to keep his fish pond full of fresh water. Be sure his inlet valve (in the sediment basin) is closed before starting to dewater the basin. Open the old bypass valve on the golf course (at the southeast corner of the pump shack, the key for the valve is in the pump shack). When that valve is closed it allows McCarty to back up water in the pipe into his pond. When the valve is open it allows water from the pipe (and sediment basin) to drain into the old creek bed. Bypass Dam , Build the bypass right at the concrete inlet. First place sand bags across bottom of creek to conform to bottom and help form a seal. Then place media bags (fabric bags filled with gravel/sand, about 3 ft square) on top of the sand bags. Place plastic membrane (one large sheet) on top of media bags and extending upstream about 15 feet out from bags. The membrane is placed about 15 feet upstream of the dam to help seal the bottom and reduce water bypass under the dam. The plastic membrane should be directed into the bypass structure. Use sand bags on top of the membrane and on the sides to seal it. Need sand bags along the upstream edge to help seal it. Dig a sump downstream of the bypass dam (about 5 to 8 feet) and place a submersible pump in it. Pump any seepage that gets past the dam back upstream. ' Be ready to rescue fish in the creek immediately after the bypass dam is placed. r HAFile Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-2057 Maplewood Sed Basin\02-1999 Pond Cleaning\Memo-Cleaning Notes.DOC\DWC\tb r tDewatering Basin Start early in the day 1 Use the 8-inch valve in the overflow weir and fish weir to initially draw the basin down. Slowly let the flow out to minimize the sediment stirred up. When the old valve at the golf course shack is opened the McCarty inlet can also be used to draw down the water level. After the water level is below the valve invert use a portable pump to remove water from the bottom of the basin. Flow from the 8-inch underdrain pipe is slow and didn't seem sufficient to dewater the sediment. Fish Rescue Allow the entire day to draw the pond down and rescue fish. The fish need to be rescued as soon as possible. When the water level is low it may get too hot or oxygen depleted to allow them to survive for more than a few hours. Draw the water level down so there is only a small pond area, then net the fish in the pond (on 9/22/99 we captured about 40 to 60 fish from the pond). The WDFW electro shocker didn't seem to work too well. We turned it up to higher level than shown on the instructions. Some fish were shocked and beached themselves, making capture easy. Wading with the shocker stirred up the silt and made it hard too see any shocked fish. When the water level was low (4 to 8 inches) it was possible to lay on the overflow weir and reach down to net fish. This worked a little better than electro shocking. When the McCarty inlet is used to drain the pond one person should be at it to net fish. A ' large number of smaller fish (1 to 2 inch) were captured there. Some of the rescued fish were placed in the top cell of the fish ladder, some were placed in the bottom cell or pool at the outlet. Recommendation - Make a large net (say 1.5' high by 3' to 4 ' wide) so it's easier to scoop and capture fish. The net will have to be made before the project begins. You could also try to use an area net cast on the bottom, herd the fish to that side, then draw it up and capture them. Silty Soil at South End of Basin Clean the basin before more than 1 foot of silt accumulates at the south end. The silty soil at the south end needs time to dewater. Allow 3 to 4 days in the hot sun after the basin is emptied. It may also help to stack the silty material in the basin and let it continue to dewater before finally hauling away for disposal. H:\File Sys\SWP - Surface Water Projects\SWP-27 - Surface Water Projects (CIP)\27-2057 Maplewood Sed Basin\02-1999 Pond Cleaning\Memo-Cleaning Notes.DOC\DWC\tb Sediment Removal ' First the trackhoe worked at the north end of the basin on the stable granular sediment. It scraped the upper channel, then moved onto the delta at the north end of the basin. It was able to sit on the delta, scrape the granular soil toward it, and form a large stockpile that would dewater. A front end loader was used to move granular soil stockpiled at the north end to a stockpile in the upper parking lot. The 1 foot granular layer above the liner felt hard when encountered, and was stable for the trackhoe to drive on. It was easy for the operator to detect when he had excavated through the sediment and reached the granular layer. The operator stockpiled some silty material on the granular soil and let it dewater over ' night. It lost some water and seemed drier and easier to work the next day. Recommend - Allow the silty soil 2 days to dry in place, then pile it in stockpiles in the basin so it can dewater further. ' Refilling the Basin It took about 12 to 16 hours to completely refill the basin at about 1/2 the flow. The 8-inch valve in the fish weir was opened about Y4 of the way and the water level in the fish weir and basin was allowed to stabilize overnight. That placed the water level in the pond at about 4 inches below the fish weir. Next the bypass dam was removed and all the creek flow went into the sediment basin. The 8-inch valve in the overflow spillway was opened to keep about 'h the total flow to the fish channel on the golf course (it should NOT be dried up). The water level in the pond was allowed to rise to just below the fish weir. The water level in the upper cell in the fish ladder needed to be draw down to drain the 18- inch bypass pipe, and avoid trapping any fish that may have swum into it. The 18-inch valve on the southwest side of the fish ladder was opened to draw down the water in the ' upper cell, the bypass pipe valve was closed, then the 18-inch fish ladder valve was closed. The 8-inch valve in the fish weir was opened to refill the upper cell from the sediment basin. The upper cell took about 1 hour to fill. The water level in the pond took about another hour to reach the top of the fish weir and begin flowing into the fish ladder. After flow had reestablished itself in the entire fish ladder the 8-inch valve in the overflow weir was closed and the sediment basin resumed normal operation. Note - The 8- and 18-inch valves had a small flow of water going through them after they were closed. After 2 or 3 days most of the flow stopped. Note - The 8-inch canal gate in the overflow weir was hard to close. The sliding gate valve seemed to be off center and scraping along one side. With too much force the valve stem bends and may eventually break. Use a hammer to tap the high side of the gate down and the valve should slide easily.
