S. Environmental Protection Agency (USEPA) has required that two wooden dolphins in close vicinity to the dry docks be removed. The removal of these dolphins was not included in our original description of activities for the project for which we received a Shoreline Substantial Development Permit (File No. LUA08-026) and an environmental review. As you suggested in our phone call yesterday, we are requesting a shoreline certificate of exception for the removal of the two dolphins. A description of the dolphins and the activities to remove them is provided below. The two dolphins are located between the two dry docks. One of the dolphins consists of 23 wooden pilings and the other consists of 10 wooden pilings. None of the wood pilings appear to be creosote -treated. The pilings are on average approximately 16 inches in diameter. There also appears to be a steel piling near one of the dry docks, just below the water's surface, that would also require removal. To remove the dolphins and the steel piling we propose to pull the pilings completely out using a vibratory pile extractor attached to a crane and a choker cable on the crane. This removal equipment will use the crane that has already been mobilized to the site for the removal of the dry docks. The vibratory pile extractor and the choker cable would be mobilized to the site using a small boat. The piling removal would occur following deconstruction of the dry docks. Piling removal may occur either prior to or following removal of the turbidity curtain, If you have any questions or need further clarification, please call me at (206) 292-2078.

Since being moved to Lake Washington in 2002, by a third party, the docks have been raised and lowered and moved to different locations within the Quendall Terminals property. They were abandoned at their current location in 2005 and are sunken on state-owned aquatic lands and just offshore of the Quendall Terminals property. The more southerly dry dock sunk in 2005 and the more northerly one sunk in 2006. The dry docks are presently too damaged to be easily raised from their sunken state. As part of the Washington Derelict Vessel Removal Program, the Washington Department of Natural Resources (WDNR) has acquired custody of these two dry docks and has assumed responsibility for their removal and disposal under RCW 79.100.The 2007 Legislature provided one time funding for this project. The dry docks are each approximately 240 feet long (200 feet at the waterline plus two 20 foot aprons), 65 feet wide, and 30 feet tall (including the 20 foot tall wing walls). Even though the dry docks are sunk, the upper portions extend five to 10 feet above the lake surface. Each dry dock weighs approximately 1,200 long tons (or 1,322 tons). The Lake Washington Dry Docks Removal Project encompasses in -water deconstruction at their current location. The debris generated from this deconstruction work would be removed from the water and sediment and placed on barges for transfer to an acceptable permitted landfill or reuse facility. The State owned aquatic lands on which the dry docks are located are part of the Quendall Terminals Superfund site. A creosote manufacturing facility operated on the upland portion of the Quendall Terminals parcel from 1917 through 1969. Historical operations at this property resulted in the release of manufactured tar products and by-products into both the aquatic sediment and upland soil area of the site. The sediment surface under and adjacent to the dry docks has been characterized by the investigators of the Quendall Terminals to contain sediment contamination. Currently, this Superfund site is undergoing further environmental characterization in preparation of a remedial investigation/ feasibility study (RI/SF) for the site cleanup. No construction activities are proposed at the upland portion of the Quendall Terminals property or within 200 feet of upland property shoreline. Activities that would occur for the deconstruction and removal of the two dry docks include completion of a hazardous materials survey; installation of a temporary in -water containment structure around the two dry docks; deconstruction and disposal of the dry docks; and possible surface sediment restoration activities following deconstruction. The project site is within the Pacific Flyway, a major north -south seasonal migration route for many bird species. The project area is used as a migratory corridor and provides rearing habitat for Puget Sound Chinook Salmon and Puget Sound Steelhead Trout. Lake Washington may also provide foraging habitat for Coastal/Puget Sound Bull Trout and contains the largest population of naturally occurring Sockeye Salmon in Washington State. A Biological Evaluation, prepared by Geomatrix.. in March 2008, identifies three endangered fish species which may be present in the project area. These are Puget Sound Chinook Salmon, Coastal/Puget Sound Bull Trout and Puget Sound Steelhead. PART TWO: ENVIRONMENTAL REVIEW _ JI In compliance with RCW 43.21 C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period. ERC Report L UA08-o26. doc City of Renton Department of Corm y & Economic Development En mental Review Committee Report DNR DRYDOCKREMOVAL LUA08-026, SM, ECF Report of April 14, 2008 Page 3 of 6 B. Mitigation Measures 1. A hazardous materials survey shall be completed by divers prior to deconstruction of the dry docks to confirm the presence or absence of hazardous materials such as asbestos -containing caulking, chinking, and wire coating and to identify the proper location for disposal of the deconstruction debris. This survey shall include sampling sediment inside the hulls for sand blast grit. This survey shall be submitted to WDNR prior to any deconstruction activity. 2. Prior to commencement of any in -water work on the dry docks, a full depth silt curtain shall be placed around both dry docks and the deconstruction equipment to contain all suspended sediment and floating debris generated from deconstruction work_ 3. Appropriate measures shall be taken to ensure that no spillage or contamination of open waters occurs as a result of transfer from derrick barges inside the silt curtain to haul barges outside the silt curtain and during hauling of the debris to the transload facility location. 4. A visual survey shall be conducted of the sediment surface within the silt curtain to collect any dry dock debris that may have fallen during deconstruction activities prior to removal of the silt curtain. 5. The applicant shall, if necessary, after the suspended sediment has settled and prior to removal of the silt curtain, ensure that a thin layer of clean sand be placed over the deconstruction area. 6. A Spill Prevention, Control, and Countermeasures (SPCC) Plan shall be developed for the project and submitted to WDNR prior to any deconstruction activities. The SPCC Plan shall outline specific measures to be taken to prevent the release or spread of discharged materials including those materials the contractor may store, use, or generate during deconstruction activities. 7. Appropriate fright -response methods shall be employed when installing the silt curtain to prevent endangered fish species from being trapped within the silt curtain. 8. Any endangered fish species which are inadvertently trapped within the silt curtain shall be removed with grab nets or other appropriate means. 9. All deconstruction activities shall take place within the allowed fish window, July 16 through December 31, and bird nesting and migration windows as determined by the Washington Department of Fish and Wildlife (WDFW). 10. Warning lights in compliance with applicable regulations of the United States Coast Guard shall be installed where necessary to reduce boating navigational hazards. 11. The crane boom used during deconstruction activities shall be marked with a white/orange flag and red light to reduce air traffic hazards. C. Exhibits Exhibit 1 Vicinity Map Exhibit 2 Proposed Site Plan Exhibit 3 Aerial Photo of Project Site D. Environmental Impacts The Proposal was circulated and reviewed b'v various City Departments and Divisions to determine whether the applicant has adequately identifed and addre.S.sed environmental impacts anticipated to occur in conjunction with the proposed development. Stgft)-ci iewers have identified that the proposal is likely to have the following prohahle impacts: 1. Earth Impacts: The State owned aquatic lands on which the dry docks are located are part of the Quendall Terminals Superfund site. A creosote manufacturing facility operated on the upland portion of the Quendali Terminals parcel from 1917 through 1969. Historical operations at this property resulted in the release of manufactured tar products and by-products into both the aquatic sediment and upland soil area of the site. The sediment surface under and adjacent to the dry clocks has been characterized by the investigators of the ERC Report LUA08-026. doe City of Renton Department of Comn & Economic Development Em nental Review Committee Report DNR DRYDOCK REMOVAL LUA08-026, .SM, ECF Report of April 14, 2008 Page 4 of 6 Quendall Terminals to contain sediment contamination. Currently, this Superfund site is undergoing further environmental characterization in preparation of a remedial investigation/ feasibility study (RI/SF) for the site cleanup. No construction activities are proposed at the upland portion of the Quendall Terminals property or within 200 feet of upland property shoreline. Activities that would occur for the deconstruction and removal of the two dry docks include completion of a hazardous materials survey; installation of a temporary in -water containment structure around the two dry docks; deconstruction and disposal of the dry clocks; and possible surface sediment restoration activities following deconstruction. The proposed action has the potential of disturbing contaminated sediments and introducing hazardous materials from the dry docks into Lake Washington. Mitigation Measures: 1. A hazardous materials survey shall be completed by divers prior to deconstruction of the dry docks to confirm the presence or absence of hazardous materials such as asbestos -containing caulking, chinking and wire coating and to identify the proper location for disposal of the deconstruction debris. This survey shall include sampling sediment inside the hulls for sand blast grit. This survey shall be submitted to WDNR prior to any deconstruction activities. 2. Prior to commencement of any in -water work on the dry docks, a full depth silt curtain shall be placed around both dry docks and the deconstruction equipment to contain all suspended sediment and floating debris generated from deconstruction work. 3. Appropriate measures shall be taken to ensure that no spillage or contamination of open waters occurs as a result of transfer from derrick barges inside the silt curtain to haul barges outside the silt curtain and during hauling of the debris to the transtoad facility location. 4. A visual survey shall be conducted of the sediment surface within the silt curtain to collect any dry dock debris that may have fallen during deconstruction activities prior to removal of the silt curtain. 5. The applicant shall, if necessary, after the suspended sediment has settled and prior to removal of the silt curtain, ensure that a thin layer of clean sand be placed over the deconstruction area. 6. A Spill Prevention, Control, and Countermeasures (SPCC) Plan shall be developed for the project and submitted to WDNR prior to any deconstruction activities. The SPCC Plan shall outline specific measures to be taken to prevent the release or spread of discharged materials including those materials the contractor may store, use, or generate during deconstruction activities. Nexus: SEPA Environmental Regulations 2. Water a. Wetland, Streams, Lakes Impacts: The entire project will be in -water within Lake Washington. The two dry docks will be deconstructed where they are sunk in the lake. The lake depth at this location ranges from 25 to 30 feet. The dry docks are located approximately 500 icct from the shoreline. See impacts described in Section D.l. Earth, above, which would also apply to Wetland, Streams, Lakes. Mitigation Measures: The mitigation measures described in Section D.I. Earth, above, also apply to Wetland, Streams, Lakes. Nexus: SEPA Environmental Regulations 3. Wildlife Impacts: The project site is within the Pacific Flyway, a major north -south seasonal migration route for many bird species. The project area is used as a migratory corridor and provides rearing habitat for Puget Sound Chinook Salmon and Puget Sound Steelhead Trout. Lake Washington may also provide foraging habitat for Coastal/Puget Sound Bull Trout and contains the largest population of naturally occurring Sockeye Salmon in Washington State. ER Report LUA08-026.doc City of Renton Department of Com) y & Economic Development En mental Review Committee Report DNR DRYDOCKREMOVAL LUA08-026, SM, ECF Report of April 14, 2008 Page 5 of 6 A Biological Evaluation, prepared by Geomatrix, in March 2008, identifies three endangered fish species which may be present in the project area. These are Puget Sound Chinook Salmon, Coastal/Puget Sound Bull Trout and Puget Sound Steelhead. The Biological Evaluation states that the proposed action may affect, but is not likely to adversely affect these species. Mitigation Measures: 1. Appropriate fright -response methods shall be employed when installing the silt curtain to prevent endangered fish species from being trapped within the silt curtain. 2. Any endangered fish species which are inadvertently trapped within the silt curtain shall be removed with grab nets or other appropriate means. 3. All deconstruction activities shall take place within allowed fish window, July 16 through December 31, and bird nesting and migration windows as determined by the Washington Department of Fish and Wildlife (WDFW). Nexus: SEPA Environmental Regulations 4. Environmental Health Hazards Impacts: As noted in Section D.I. Earth, above, sediments within the silt curtain may contain hazardous materials. Also, as previously noted, a hazardous materials survey will be conducted to determine if the dry docks contain any hazardous materials. Contaminated sediment within the project area will be addressed as part of the Quendall Terminals Superfund Site and will not be removed as part of this project. Mitigation Measures: The mitigation measures listed in Section D.1. Earth, above, address containing and handling any contaminated suspended sediment and dry dock debris with potentially hazardous materials associated with the removal of the dry docks as well as water quality monitoring and sampling. Nexus: SEPA Environmental Regulations 5. Transportation Impacts: The dry docks in their current location pose a potential hazard to navigation on Lake Washington. Deconstruction of the dry docks and removal of subsequent debris will remove this hazard. During deconstruction and removal activities barges (including derrick barges, a crane and a long -reach excavator), tugs, and support vessels will be used to access the site as well as bring materials and equipment on and off the project site. Air traffic may potentially be impacted by the placement of the the crane used during deconstruction activities. Mitigation Measures: 1. Warning lights in compliance with applicable regulations of the United States Coast Guard shall be installed where necessary to reduce boating navigational hazards. 2. The crane boom used during deconstruction activities shall be marked with a white/orange flag and red light to reduce air traffic hazards. Nexus: SEPA Environmental Regulations E.

The site is located on state-owned aquatic land within the Harbor Area of Lake Washington. The King County parcel number for this aquatic land is 2924059014. The adjacent property, located directly to the east of this aquatic land and the dry docks, has a physical address of 4503 Lake Washington Blvd, Renton. The dry docks are located approximately 400 feet waterward of the take Washington shoreline. In order to remove these dry docks from the project site, an anchored full -depth silt curtain will be placed at the site surrounding the dry docks and deconstruction equipment. This enclosed deconstruction area will contain a maximum of approximately 3 acres. Land Use Permits Required for the Proposed Project: Shoreline Substantial Development Permit and Environmental Review Zoning Designation for Site and Adjacent Properties: State-owned aquatic land is generally not classified using upland zoning categories. The adjacent upland properties are zoned as Commercial/Office/Residential (COR). Current Use of the Site and Existing Improvements: The project site is on state-owned aquatic land within Lake Washington that is designated as a harbor area and is managed by WDNR. The site is open water that has two sunken wood dry docks on it and several abandoned piling dolphins. Total Estimated Construction Cost: $1-2 million Proposed Project: The purpose of this project proposed by WDNR is to remove two derelict wood dry docks currently sunken on the sediment surface in southern Lake Washington. Since being moved to Lake Washington in 2002 by a third party, the dry docks have been raised and lowered and moved to different locations within the Quendall Terminals property. They were abandoned in their current location in late 2005 and are sunken on state-owned aquatic lands just offshore of the Quendall Terminals property. The more southerly dry dock sunk in December 2005 and the more northerly one sunk in December 2006. The dry docks are presently too damaged to be easily raised from their sunken state. As part of the Washington derelict vessel removal program, WDNR has acquired custody of these two dry docks and has assumed responsibility for their removal and disposal under RCW 79.100. The 2007 Legislature provided one-time funding for this project. F 1prolectsl!)NR-Ml)( T3000 PermittinglCily of Page 1 of 4 Renton Shoreline Perm 6Renton Projeci_Narralive_031908.doc 03/21 /08 - F._L.O._Y. D...I SNIDER The dry docks are each approximately 240 feet long (200 feet at the waterline plus two 20 foot aprons), 65 feet wide, and 30 feet tall (including the 20 foot tall wingwalls). Even though the dry docks are sunk, the upper portions of the wingwalls extend 5 to 10 feet above the lake surface. Each dry dock weighs approximately 1,200 long tons (or 1344 tons). The dry docks present multiple problems in their current sunken arrangement. The dry docks pose a navigational hazard to boaters and are a visual eyesore in the lake. They are an attractive nuisance that draws people to a Superfund site. The dry docks pose an impact on salmon within the lake as they provide cover, shade, and focal points for predators of juvenile salmon. They also negatively affect other aquatic species and vegetation within Lake Washington, as they rest on a large footprint of lake sediment. Additionally, the dry docks encumber the Quendall Terminals CERCLA site from moving forward with their sediment investigation in this area of the lake. These issues can all be remedied by the removal of the dry docks. The general scope of the proposed Lake Washington Dry Docks Removal Project is that the two wood dry docks would be deconstructed in -water at their current location in Lake Washington. The dry dock debris generated from this deconstruction work would be removed from the water and sediment and placed on barges for transfer to an acceptable permitted landfill or reuse facility. All construction activities associated with the removal of these dry docks would occur within Lake Washington over state-owned aquatic lands managed by WDNR. The state-owned aquatic lands on which the dry docks are located are part of the Quendall Terminals Superfund site. A creosote manufacturing facility operated on the upland portion of the Quendall Terminals parcel, to the east of the dry dock project site, between 1917 and 1969, and historical operations at this property resulted in the releases of manufactured tar products and by-products into both the aquatic sediment and upland soil areas of the site. The sediment surface under and adjacent to the dry docks has been characterized by Quendall Terminals investigations to contain surface sediment contamination, including dense non -aqueous phase liquid (DNAPL) and polycyclic aromatic hydrocarbons (PAHs), related to the Quendall Terminals site. Currently, this Superfund site is Undergoing further environmental characterization in preparation of a remedial investigation/feasibility study (RUFS) for the site cleanup. No construction activities are proposed at the upland portion of the Quendall Terminals Property or within 200 feet of the upland property shoreline. This spring, prior to the dry dock deconstruction and removal work, a hazardous materials survey will be completed on the dry docks. For the deconstruction and removal of the two dry docks, activities that would occur include installation of a temporary in -water containment structure (anchored silt curtain) around the two dry docks; deconstruction and disposal of the dry docks; and possible surface sediment restoration activities following deconstruction. The deconstruction and removal of the dry docks will be completed within the in -water worm window of July 16, 2008 to December 31, 2008. The anticipated project start date is July 16, 2008 and all in -water project activities are anticipated to be completed by early October 2008. The hazardous materials survey and the deconstruction and removal activities are described in further detail below. F3projeds40NR-LW0MT3040PermittNXCityof Page 2 of 4 Renton Shoreline PermMerrion_Projed Narralive_031gMdoc 03121 /08 ELOYD 1 SNIDER Hazardous Materials Survey The types of hazardous materials that could potentially be contained in or on wood dry dock structures are asbestos -containing caulking, chinking, and wire coating, sand blast grit embedded in the wood decking and wingwalls, and marine paint containing toxic compounds such as polychlorinated biphenols (PCBs), lead, other heavy metals and TBT. Visual diver inspections performed to date on the Lake Washington dry docks do not indicate that significant quantities of these hazardous materials are present on or within the structures. During a recent (2007) dive survey of the dry docks, no significant quantities of sand blast grit were observed on the deck or within the ballast tanks and photos taken on one of the Lake Washington dry docks while it was still floating show that the deck and wingwalls are primarily free of marine paint. It is not likely that the minor amounts of sand blast grit embedded in the wood decking and wingwalls would be characterized as hazardous material. A hazardous materials survey will be completed by divers prior to deconstruction of the Lake Washington dry docks to confirm the presence or absence of hazardous materials such as asbestos -containing caulking, chinking and wire coating and to identify the proper location for disposal of the deconstruction debris. The survey will also include sampling sediment inside the dry dock hulls to investigate for the potential presence of sand blast grit. Installation of a Temporary In -Water Containment Structure Prior to beginning any in -water work on the dry docks, a full depth anchored silt curtain would be placed around both of the dry docks and the deconstruction equipment to contain all suspended sediment and floating debris generated from the deconstruction work. This silt curtain would remain in place and the deconstruction equipment would remain on -site after deconstruction activities were completed until all water quality permit conditions were satisfied. The deconstruction activities will be completed in water depths of approximately 20 to 25 feet and within a lake environment that does not contain significant currents or tidal fluctuations. These conditions are favorable for use of a full depth, anchored silt curtain to contain turbidity and construction debris. The maximum area within the silt curtain (or the project deconstruction area) is expected to encompass roughly 3 acres. Deconstruction and Disposal In -place deconstruction of the dry docks would likely occur using up to two derrick barges (one mounted with a long -reach excavator and potentially another with a crane) and two material disposal barges. The barge with the long -reach excavator and one of the disposal barges would be placed inside the closed silt curtain and would remain there during completion of all deconstruction work. The long reach excavator would deconstruct the wooden dry docks into pieces suitable for loading into the disposal barge located within the silt curtain. The crane barge (if used) would likely be positioned outside the silt curtain to transfer the deconstruction material from the disposal barge inside the silt curtain to a second disposal barge located outside the silt curtain. If the crane barge is not planned for use during deconstruction activities, the barge with the long -reach excavator would be responsible for the transfer of the deconstruction debris to the material transfer barge outside the anchored silt curtain. The dry dock deconstruction debris would be transferred from a disposal barge directly into transport containers lined with impermeable liners once the debris was cut down to a size F 1projacts%0NR-LWUD%T3000 PermiltinglChy of Page 3 of 4 Renton Shoreline PermANRenton_Projeu_Narfalive 031Ml.doc 03/21108 FLOYD I_SNIDER suitable for loading into the containers. Cutting the debris into suitable size pieces and transferring it into the containers could occur either at the project site or at a transload facility, If conducted at the project site, empty lined containers would be loaded onto the disposal barge before it was moved to the site, the debris would then be cut on the barge and loaded into the containers at the site, and then the container would be transferred off of the barge directly onto a truck chassis when the barge returned to the transload facility. Alternatively, the disposal barge loaded with deconstruction debris could be towed to the transload facility, where containers could then be loaded onto the barge, the debris would be cut on the barge and then loaded into the containers, and then the container would be transferred off of the barge onto a truck chassis. It is assumed that it would take a minimum of four barge loads to haul away all deconstruction debris from the project site. The barges would be towed to a transload location where the containers with the dry dock debris would then be transferred to trucks. The transload facility location has not been determined at this time, but will likely be an existing marine industrial facility in lake Washington or Seattle. From the transload site, the dry dock debris will be transported to a permitted disposal facility or reuse facility by road or rail. During the in -water deconstruction work, water quality monitoring would be conducted to ensure compliance with water quality permit requirements outside the silt curtain. Additionally, water quality verification testing would likely be required after completion of the deconstruction activities within the silt curtain area to ensure that permit requirements are satisfied before the silt curtain is opened and removed for disposal. The Washington Department of Ecology is planning to issue a water quality modification for this proposed project (WAC 173-201A-410), which is expected to outline best management practices (BMPs) to be used to protect water quality at the site and the specific water quality monitoring activities required for this project. Should any DNAPL be released from the subsurface sediment within the silt curtain during the deconstruction activities, absorbent materials will be used to remove the DNAPL, as required. Following the deconstruction of the dry docks, a visual survey of the sediment surface within the silt curtain would be performed to collect any dry dock debris that had fallen during the deconstruction work. Surface Sediment Restoration Activities Once dry dock deconstruction activities are complete, the silt curtain would likely need to remain in place for days to weeks to allow suspended sediment generated by the construction activities to settle out and return to the sediment surface within the deconstruction area. Once water quality verification testing was completed and water quality requirements met within the deconstruction area, the silt curtain would be removed. A thin layer of clean sand may be placed over the deconstruction area once the suspended lake sediment has settled out. Assuming the deconstruction area enclosed by the silt curtain is 3 acres and 6-inches of sand is placed over this area, the volume of sand that would be required is approximately 2,400 cubic yards (approximately 3,300 tons). Sand material will be tested to ensure it will not cause adverse impacts to the surrounding sediments after placement.

The anticipated project start date is July 16, 2008 and all project activities are anticipated to be completed by early October 2008. Hours and Days of Operations: Dry dock deconstruction activities would occur during normal working hours (Monday through Friday, during daylight hours). No construction activities are planned during weekends or night time. Proposed HaulinglTransportation Routes: The proposed project is located within Lake Washington. Barges, tugs, and support vessels will be used to access the site as well as bring materials and equipment on and off the project site. The project will use barges for hauling the dry dock debris from the project site to a transload facility. It is anticipated that a minimum of four barge loads of debris will be required to move the approximate 3,000 tons of dry dock debris from the project site to the transload facility. The transload facility location has not been determined at this time, but will likely be an existing marine industrial facility in Lake Washington or Seattle. From the transload site, the dry dock debris will be transported to a permitted disposal facility or a reuse facility by road or rail. The adjacent upland properties are not anticipated to be used as hauling or transportation routes to the project site. Mitigation Measures: Construction mitigation measures that will be implemented during the dry docks removal project include the following: • All in -water work will occur during the allowed in -water work window. Construction activities will only occur during day light hours. • A full depth, anchored silt curtain will be placed around the two dry docks and the deconstruction equipment (a derrick barge with an excavator and a debris barge) to contain turbidity and debris generated from the deconstruction activities. • Efforts will be made to minimize the number of fish enclosed inside the silt curtain as it is deployed at the project site and to remove any fish within the curtain following its placement. During the placement of the silt curtain, fish will be driven away from the project area using a noise generating system to create an acoustic disturbance. Following placement of the silt curtain and prior to the start of deconstruction activities, an underwater video survey will be conducted within the enclosed area of the silt curtain, particularly around the dry docks, to record the potential presence of any fish. If a large number of fish are observed within the enclosed silt curtain area, efforts will be implemented to collect the fish with grab nets and to release them outside the enclosed area prior to the start of deconstruction activities. • The anchored silt curtain will not be opened throughout the deconstruction activities. The deconstruction equipment inside of the silt curtain will remain there throughout the FWofec19l0NR-LWDMT3WQ Permilling0ty of Page 1 of 3 Renton Shoreline PermRenton Conslrudion_Miligation_031908,doe 03/21 /08 FLOYD I SNIDER deconstruction work and after the work has been completed until suspended sediment within the silt curtain has settled out sufficiently. Water quality monitoring will occur within the silt curtain area after completion of the deconstruction activities to ensure that water quality standards are restored before the silt curtain is opened and removed for disposal. • Water quality monitoring will be conducted outside the silt curtain during the deconstruction activities to ensure compliance with water quality permit requirements. • The silt curtain will be placed within the harbor area (inside the outer harbor line) to the greatest degree possible to minimize the generation of potential navigation hazards within the lake. Deconstruction equipment that is located outside of the silt curtain during the deconstruction activities will also be staged inside the outer harbor line to the greatest extent possible. • Proper lighting will be placed on the silt curtain and all deconstruction equipment to ensure that they are visible to vessels that may pass by the project site at night. The lighting will be adjusted away from the water surface to the extent practicable. • To minimize noise disturbance associated with the proposed project, driven piles will not be used for anchoring the silt curtains. • Barge dewatering of the dry dock debris will occur only inside of the silt curtain. • The crane, located on a barge outside the silt curtain, which may be used to transfer the dry dock debris from the debris barge inside of the silt curtain to a transfer barge located outside the silt curtain, will not be allowed to swing directly over open water. This would also apply if the long -reach excavator is used for the transfer of debris between the barges. An apron will be placed between the storage barge (located inside the silt curtain) and the transfer barge (located outside the silt curtain) to collect potential debris and turbid water that may be spilled during the transfer process and prevent this material from entering the lake (outside of the silt curtain). • The selected contractor will observe the integrity of the silt curtain on a frequent basis and will conduct routine visual inspections for any floating debris outside the silt curtain. Any debris observed outside of the silt curtain will be immediately removed. • Erosion control materials (i.e., straw bales and or filter fabric) will be placed around the deconstruction debris on the transport barge while it is being towed from the project site to the transload facility. • Efforts will be made during the deconstruction activities to minimize the amount of sediment pulled up with the deconstruction debris. Any sediment that accumulates on the barges as a result of this work will be collected following completion of the deconstruction activities for transport to a permitted disposal facility. • Dry dock deconstruction debris will be transferred from the barges directly into loading containers and not stockpiled on the ground at the transload facility. Empty containers would be loaded directly onto the transfer barge, filled with debris, and then transferred off of the barge. Container loading could occur at the project site or at the transload facility. • The containers in which the dry dock debris is placed will be lined with impermeable liners prior to be being filled.

This sand would have a minimal fines content to reduce the potential for elevated turbidity during placement. Placement of the thin sand layer would be completed in a manner minimizing disturbance to the sediment surface. • A hazardous materials survey will be performed on the two dry docks prior to their deconstruction. If any asbestos -containing materials are present on the dry docks or if there is marine paint on the dry docks or sand blast grit embedded in the wood of the dry docks, these materials can still be considered manageable as deconstruction debris as they would be removed from the project site with the wood deconstruction debris. Additionally, a sediment sampling investigation will be completed inside the hulls of the dry docks prior to the start of deconstruction activities. If the sediment collected within the hulls is determined to be grit -impacted, then this sediment will be removed from the hulls prior to the deconstruction work. • All vessels operating at the site will be prevented from grounding in the lake sediment. However, barges will be allowed to spud into position at the site. • Regular inspections and maintenance will be performed on the barges, heavy construction equipment, and generators used during the deconstruction work to assure proper operation. • A Spill Prevention, Control, and Countermeasures (SPCC) Plan will be developed for the project by the selected contractor. This SPCC Plan will outline specific measures to be taken to prevent the release or spread of discharged materials including those materials the contractor may store, use, or generate during construction activities. These items include, but are not limited to, gasoline, oils, and chemicals. To reduce or control air emissions from the project, the construction equipment used at the site will meet King County emission requirements. • The project will be accomplished in accordance with a site -specific health and safety plan, to ensure that construction personnel who may encounter contaminated media are appropriately trained, prepared, and outfitted, and that management of contaminated media is conducted in accordance with relevant local, state and federal requirements.

January. A biological evaluation of the project site is currently in preparation for consultation with NMFS and USFWS that addresses ESA -listed species in Lake Washington. Prior to deconstruction of the two wood dry docks, a hazardous materials survey will be performed on these structures to determine if asbestos containing materials or other hazardous materials are present on the dry docks and to identify appropriate disposal options for the dry dock debris. Based on multiple visual inspections that have been completed on the two Lake Washington dry docks, it is unlikely that significant quantities of any hazardous materials is present on or within these structures. Other documents that will be prepared prior to the project work include a Site -Specific Health and Safety Plan and a Spill Prevention, Control, and Countermeasures (SPCC) Plan. To BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY 9. Do you know whether applications are pending for governmental approvals of other proposals directly affecting the property covered by your proposal? If yes, explain. The state-owned aquatic lands on which the dry docks are located are part of the Quendall Terminals Superfund site. The Quendall Terminals site is a former creosote manufacturing facility and has been contaminated with coal tar, pitch, creosote, and other hazardous chemicals. In 2006, EPA signed an Administrative Order on Consent (AOC) with the two potentially responsible parties (PRPs) for the site which requires the PRPs to complete a remedial investigation and feasibility study to identify the extent of contamination and propose cleanup alternatives for the Quendall Terminals site. Areas of sediment contamination related to the former creosote manufacturing operations have been noted in the area of the two dry docks. A discussion of the contaminants observed in these sediments is discussed further below in Section 13.7.a. Removing the two dry docks from these contaminated sediments will allow additional investigation and cleanup of the sediments by the Quendall Terminal PRPs under CERCLA to move forward. 10. List any government approvals or permits that will be needed for your proposal, if known. Section 10 Permit and Section 404 Permit, Army Corps of Engineers Hydraulic Permit Approval (HPA), Washington Department of Fish and Wildlife 401 Water Quality Certification, Washington Department of Ecology Aquatic Use Authorization (Right of Entry), Washington Department of Natural Resources Shoreline Substantial Development Permit, City of Renton Approval, Environmental Protection Agency 11. Give brief, complete description of your proposal, including the proposed uses and the size of the project and site. There are several questions later in this checklist that ask you to describe certain aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may modify this form to include additional specific information on project description.) The purpose of this project proposed by WDNR is to remove two derelict wood dry docks currently sunken on the sediment surface in southern Lake Washington. Since being moved to Lake Washington in 2002 by a third party, the dry docks have been raised and lowered and moved to different locations within the Quendall Terminals property. They were abandoned in their current location in late 2005 and are sunken on state-owned aquatic lands just offshore of the Quendall Terminals property. The more southerly dry dock sunk in December 2005 and the more northerly one sunk in December 2006. The dry docks are too damaged to be easily raised from their sunken state. As part of the Washington derelict vessel removal program, WDNR has acquired custody of these two dry docks and has assumed responsibility for their removal and disposal under RCW 79.100. The 2007 Legislature provided one-time funding for this project. The dry docks are each approximately 200 feet long, 65 feet wide, and 30 feet tall, including the 20 foot tall wingwalls. Even though the dry docks are sunk, the upper portions of the wingwalls extend 5 to 10 feet above the lake surface. Each dry dock weighs approximately 1,200 long tons (or 1344 tons). The dry docks present multiple problems in their current sunken arrangement. The dry docks pose a navigational hazard to boaters and are a visual eyesore in the lake. They are an attractive nuisance that draws people to a Superfund site. The dry docks pose an impact on salmon within the lake as they provide cover, shade, and focal points for predators of juvenile salmon. They also negatively affect other aquatic species and vegetation within Lake Washington, as they rest on a large footprint of lake sediment. Additionally, the dry docks encumber the Quendall Terminals CERCLA site from moving forward with their sediment investigation in this area of the lake. These issues can all be remedied by the removal of the dry docks. TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY The general scope of the proposed Lake Washington Dry Docks Removal Project is that the two wood dry docks would be deconstructed in -water at their current location in Lake Washington. The dry dock debris generated from this deconstruction work would be lifted from the water and sediment and placed on barges for transfer to an acceptable permitted landfill facility or reuse facility. All construction activities associated with the removal of these dry docks would occur within Lake Washington over state-owned aquatic lands managed by WDNR. The state-owned aquatic lands on which the dry docks are located are part of the Quendall Terminals Superfund site. A creosote manufacturing facility operated on the upland portion of the Quendall Terminals parcel, to the east of the dry dock project site, between 1917 and 1969, and historical operations at this property resulted in the releases of manufactured tar products and by-products into both the aquatic sediment and upland soil areas of the site. The sediment surface under and adjacent to the dry docks has been characterized by Quendall Terminals' investigations to contain surface sediment contamination, including dense non -aqueous phase liquid (DNAPL) and polycyclic aromatic hydrocarbons (PAHs), related to the Quendall Terminals site. Currently, this Superfund site is undergoing further environmental characterization in preparation of a remedial investigation/feasibility study (RI/FS) for the site cleanup. No construction activities are proposed at the upland portion of the Quendall Terminals Property or within 200 feet of upland property shoreline. For the deconstruction and removal of the two dry docks, activities that would occur include completion of a hazardous materials survey; installation of a temporary in -water containment structure around the two dry docks; deconstruction and disposal of the dry docks; and possible surface sediment restoration activities following deconstruction. These activities are described in further detail below. Hazardous Materials Survey The types of hazardous materials that could potentially be contained in or on wood dry dock structures are asbestos -containing caulking, chinking, and wire coating, sand blast grit embedded in the wood decking and wingwalls, and marine paint containing the toxic compounds such as polychlorinated biphenols (PCBs), lead, other heavy metals and TBT. Visual diver inspections performed to date on the Lake Washington dry docks do not indicate that significant quantities of these hazardous materials are present on or within the structures. During a recent (2007) dive survey of the dry docks, no noticeable quantities of sand blast grit were observed on the deck or within the ballast tanks and photos taken on one of the Lake Washington dry docks while it was still floating show that the deck and wingwalls are primarily free of marine paint. It is not likely that the minor amounts of sand blast grit embedded in the wood decking and wingwalls would be characterized as hazardous material. A hazardous materials survey will be completed by divers prior to deconstruction of the Lake Washington dry docks to confirm the presence or absence of hazardous materials such as asbestos - containing caulking, chinking and wire coating and to identify the proper location for disposal of the deconstruction debris. The survey will include sampling sediment inside the hulls for sand blast grit. Installation of a Temporary In -Water Containment Structure Prior to beginning any in -water work on the dry docks, a full depth anchored silt curtain would be placed around both of the dry docks and the deconstruction equipment to contain all suspended sediment and floating debris generated from the deconstruction work. This silt curtain would remain in place and the deconstruction equipment would remain on -site after deconstruction activities were completed until all water quality permit conditions were satisfied. The deconstruction activities will be completed in water depths of approximately 20 to 25 feet and within a lake environment that does not contain significant currents or tidal fluctuations. These conditions are favorable for use of a full depth 4 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY silt curtain to contain turbidity and construction debris. The area within the silt curtain (or the project deconstruction area) is expected to encompass roughly 3 acres. Deconstruction and Disposal In -place deconstruction of the dry docks would likely occur using two derrick barges (one mounted with a crane and another with a long reach excavator) and two material disposal barges. The barge with the long -reach excavator and one of the disposal barges would be placed inside the closed silt curtain and would remain there during completion of all deconstruction work. The long reach excavator would deconstruct the wooden dry docks into pieces suitable for loading into the disposal barge located within the silt curtain. The crane barge would be positioned outside the silt curtain to transfer the deconstruction material from the disposal barge inside the silt curtain to a second disposal barge located outside the silt curtain. Dry dock debris would be transferred from the disposal barges directly into loading containers lined with impermeable liners once the debris was cut down to a size suitable for loading into the containers. The transfer of the debris into the containers could occur either at the project site or at the transload facility. Empty lined containers would be loaded onto the haul barge, filled with debris, and then the container would be transferred off of the barge directly onto a truck chassis. It is assumed that it would take at least four barge loads to haul away all deconstruction debris from the project site. The barges would be towed to a transload location where the containers with the dry dock debris would then be transferred to trucks. The transload facility location has not been determined at this time, but will likely be an existing marine industrial facility in Lake Washington or Seattle. From the transload site, the dry dock debris will be transported to a permitted disposal facility or reuse facility by road or rail. During the in -place deconstruction work, turbidity monitoring would be conducted to ensure compliance water quality permit requirements outside the silt curtain. Additionally, water quality verification testing would likely be required after completion of the deconstruction activities within the silt curtain area to ensure that permit requirements are satisfied before the silt curtain is opened and removed for disposal. The Washington Department of Ecology is planning to issue a short-term water quality modification for this proposed project (WAC 1 i3-241 A-41 0), which would is expected to outline the specific water quality monitoring and testing activities required for this project. Should any non - aqueous phase liquid (NAPL) be released from the subsurface sediment within the silt curtain during the deconstruction activities, absorbent materials will be used to remove the NAPL, as required. Following the deconstruction of the dry docks, a visual survey of the sediment surface within the silt curtain would be performed to collect any dry dock debris that had fallen during the deconstruction work. Surface Sediment Restoration Activities Once dry dock deconstruction activities are complete, the silt curtain would likely need to remain in place for days to weeks to allow suspended sediment generated by the construction activities to settle out and return to the sediment surface within the deconstruction area. A thin layer of clean sand may be placed over the deconstruction area once the suspended lake sediment has settled out. Once water quality verification testing was completed and water quality requirements met within the deconstruction area, the silt curtain would be removed. TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY 12. Location of the proposal. Give sufficient information for a person to understand the precise location of your proposed project, including a street address, if any, and section, township, and range, if known. If a proposal would occur over a range of area, provide the range or boundaries of the site(s). Provide a legal description, site plan, vicinity map, and topographic map, if reasonably available. While you should submit any plans required by the agency, you are not required to duplicate maps or detailed plans submitted with any permit applications related to this checklist. The project site, where the dry docks are currently sunk, is near the eastern shore of Lake Washington, north of the mouth of May Creek in the W % of the SW '/a Section 29, Township 24N, Range 5E. The general project site location is shown on the Vicinity Map in Figure 1. The site is located on state-owned aquatic land that is within the Harbor Area of Lake Washington. The King County parcel number for this aquatic land is 2924059014. These aquatic bedlands are managed for the public by the Washington State Department of Natural Resources, Aquatic Resources Program. The adjacent property, located directly to the east of this aquatic land and the dry docks, has a physical address of 4503 Lake Washington Blvd, Renton and the King County parcel number for this property is 2924059002. This property is owned by Quendall Terminals and includes both submerged shorelands and the adjacent uplands. Figure 2 is a site plan, showing the location of the dry docks and project site in relation to the adjacent Quendall Terminals property and the shoreline. The dry docks are located approximately 400 feet west of the Lake Washington shoreline. B. ENVIRoNMENTAL ELEMENTs 1. Earth a. General description of the site (circle one): Flat, roiling, hilly, steep slopes, mountainous, other...... Flat aquatic lands below the ordinary high water mark. The water depth at this location ranges from 25 to 30 feet deep. b. What is the steepest slope on the site (approximate percent slope)? The steepest slope on the aquatic lands in the vicinity of the dry docks is approximately a 10 percent slope. In general, the aquatic lands at the project site have less than a 3 percent slope. c. What general types of soils are found on the site (for example, clay, sand, gravel, peat, muck)? If you know the classification of agricultural soils, specify them and note any prime farmland. The sediment surface at this location has been described as typically a fine silt or mud. Sediment analyses as part on the Quendall Terminals Superfund site investigation indicate that surface sediments located on or in the vicinity of the project site are sandy silts to silty sands. d. Are there surface indications or history of unstable soils in the immediate vicinity? If so, describe. The Seattle Fault runs directly under Mercer Island and through Lake Washington. However, in the project area there is no known history of unstable soils or surface indications of unstable soils. This site is not designated as a landslide hazard on the King Count Sensitive Areas Ordinance map. e. Describe the purpose, type, and approximate quantities of any filling or grading proposed. Indicate source of fill. A thin layer of clean sand may be placed over the deconstruction area once the suspended lake sediment has settled out. If this occurs, the sand layer would likely be placed over approximately 3 acres, the area inside the silt curtain. Assuming the deconstruction area enclosed by the silt curtain is 6 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY 3 acres and 6-inches of sand is placed over this area, the volume of sand that would be required is approximately 2,400 cubic yards. The source of sand material would be a local supplier selected by the marine contractor. Sand material will be tested to ensure it will not cause adverse impacts to the surrounding sediments after placement. f. Could erosion occur as a result of clearing, construction, or use? If so, generally describe. Localized disturbance of the lake sediment will occur within the silt curtain as a result of deconstruction of the dry docks. See the response to Section B.1.h below describing the measures that will be implemented to control and monitor turbidity during the project. g. About what percent of the site will be covered with impervious surfaces after project construction (for example, asphalt or buildings)? This project would not create any permanent impervious surfaces. h. Proposed measures to reduce or control erosion, or other impacts to the earth, if any: Measures that will be implemented to reduce or control turbidity within Lake Washington associated with the deconstruction work and to prevent any dry dock debris from leaving or remaining in the project area include the following: • A full depth anchored silt curtain will be placed around the two dry docks and the deconstruction equipment (a derrick barge with an excavator and a debris barge) to contain turbidity and debris generated from the deconstruction activities. • The silt curtain will not be opened throughout the deconstruction activities. The deconstruction equipment inside of the silt curtain will remain there throughout the deconstruction work and after the work has been completed until suspended sediment within the silt curtain has settled out sufficiently. Water quality verification testing will likely occur within the silt curtain area after completion of the deconstruction activities to ensure that water quality standards are restored before the silt curtain is opened and removed for disposal. • Water quality monitoring will be conducted outside the silt curtain during the deconstruction activities to ensure compliance with water quality permit requirements. • Barge dewatering of the dry dock debris will occur only inside of the silt curtain. • The crane, located on a barge outside the silt curtain, that is used to transfer the dry dock debris from the debris barge inside of the silt curtain to a haul barge located outside the silt curtain will not be allowed to swing directly over open water. A platform will be placed under the path of the crane bucket between the silt curtain and the haul barge to collect debris and turbid water that may be spilled during the transfer process and prevent this material from entering the lake. • Dry dock debris will be transferred from the barges directly into loading containers and not stockpiled on the ground at the transload facility. Empty containers would be loaded onto the haul barge, filled with debris, and then transferred off of the barge. Container loading could occur at the project site or at the transload facility. • The containers in which the dry dock debris is placed will be lined with impermeable liners prior to be being filled. 1M.M91#33Ii"10D3 W.1"I[•MOd EVALUATION FOR AGENCY • Following the deconstruction of the dry docks, a visual survey of the sediment surface within the silt curtain would be performed to collect any dry dock debris that had fallen during the deconstruction work. • As stated above in Section B.1.e, a thin layer of clean sand maybe placed over the entire deconstruction area following the settling of the suspended lake sediment out of the water column. The clean sand would be placed prior to removal of the silt curtain. This sand would have a minimal fines content to reduce the potential for elevated turbidity during placement. 2. Air a. What types of emissions to the air would result from the proposal (i.e., dust, automobile, odors, industrial wood smoke) during construction and when the project is completed? If any, generally describe and give approximate quantities if known. There will be a temporary increase in localized emissions from the construction equipment and the generators used on the barges used to deconstruct the dry docks, however, effects are expected to be minimal. Emissions will also be generated during the transport of the dry dock debris to a landfill or reuse facility. No emissions will result from this project once this project is completed. b. Are there any off -site sources of emissions or odor that may affect your proposal? If so, generally describe. There are no off -site sources of emissions or odor that would affect this project. c. Proposed measures to reduce or control emissions or other impacts to air, if any: Equipment used at the site will meet King County emission requirements. 3. Water a. Surface: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. The project site is located within Lake Washington on state-owned aquatic land. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. Yes, the entire project would occur in -water within Lake Washington. The two wood dry docks would be deconstructed where they are sunk in the lake. The lake depth at this location ranges from 25 to 30 feet deep. The dry docks are located approximately 500 feet from the shoreline. A description of the in -water work for this project is provided above in Section A.11. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. No dredging would occur as part of this project. The dry docks would be deconstructed and removed from the lakebed. Lake sediment will likely be disturbed during this process, but it will not be removed TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY from the lake. Suspended lake sediment within the silt curtain will be allowed to settle out after the deconstruction work has been completed and before the silt curtain is removed. A thin layer of clean sand may be placed over the deconstruction area once the suspended lake sediment has settled out. If this occurs, the sand layer would likely be placed over approximately 3 acres, the area inside the silt curtain. Assuming the deconstruction area enclosed by the silt curtain is 3 acres and 6-inches of sand is placed over this area, the volume of sand that would be required is approximately 2,400 cubic yards. The source of sand material would be a local supplier selected by the marine contractor. Sand material will be tested to ensure it will not cause adverse impacts to the surrounding sediments after placement. 4) Will the proposal require surface water withdrawals or diversions? Give general description, purpose, and approximate quantities if known. The project would not require surface water withdrawals or diversions. 5) Does the proposal lie within a 100-year floodplain2 If so, note location on the site plan. No, the entire project occurs in -water within Lake Washington. 6) Does the proposal involve any discharges of waste materials to surface waters? If so, describe the type of waste and anticipated volume of discharge. An excavator will be used to deconstruct the wood dry docks in the water. Pieces of the dry dock debris will be released into the surface water as a result of this deconstruction work and will fall to the bottom of the lake within the enclosed work area. Once the two wood dry docks are deconstructed, a sweep of the sediment surface will be completed to remove potential residual debris from the sediment surface. All debris generated by the deconstruction activities, including debris that ends up on the sediment surface, would be collected and removed from the project site. A hazardous materials survey will be completed prior to deconstruction of the Lake Washington docks to confirm the presence or absence of these hazardous materials such as asbestos -containing caulking, chinking and wire coating. The survey will include sediment sampling inside the hulls for sand blast grit. If results of this survey indicate that asbestos -containing materials are present on the dry docks or if there is marine paint on the dry docks or sand blast grit embedded in the wood of the dry docks, these materials can still be considered manageable as deconstruction debris. These materials will be removed with the wood deconstruction debris as the dry dock structures are cut into pieces and placed into a disposal barge. If the sediment within the hulls shows a predominance of sand blast grit, then this sediment will be removed from the hulls prior to the deconstruction work. b. Ground: 1) Will ground water be withdrawn, or will water be discharged to ground water? Give general description, purpose, and approximate quantities if known. No groundwater will be withdrawn and no water would be discharged into ground water during this project. 2) Describe waste material that will be discharged into the ground from septic tanks or other sources, if any (for example: Domestic sewage; industrial, containing the TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY following chemicals... ; agricultural; etc.). Describe the general size of the system, the number of such systems, the number of houses to be served (if applicable), or the number of animals or humans the system(s) are expected to serve. Not applicable, the proposed project does not involve any discharge of waste materials to ground water. c. Water runoff (including stormwater): 1) Describe the source of runoff (including storm water) and method of collection and disposal, if any (include quantities, if known). Where will this water flow? Will this water flow into other waters? If so, describe. There are no sources of runoff associated with this project. The project would take place in the surface waters of Lake Washington. The lake water currently free flows between the inside and outside of the two dry docks. No surface water will be collected or disposed of as part of this project. 2) Could waste materials enter ground or surface waters? If so, generally describe. No waste material that is not already in the water would enter the surface water. With the removal of the two dry docks, this project would ultimately create a net removal of waste from the surface water. As stated above, a sweep of the sediment surface will be completed to remove debris from the sediment following the deconstruction of the dry docks. d. Proposed measures to reduce or control surface, ground, and runoff water impacts, if any: Please refer to Section B.1.h above, as many of the measures that will be implemented to reduce or control surface water impacts resulting from the project have already been listed in this earlier section. The mitigation measures listed in this earlier section address handling turbidity and dry dock debris associated with the removal of the dry docks and water quality monitoring and sampling. Additionally, a Spill Prevention, Control, and Countermeasures (SPCC) Plan will be developed for the project by the selected contractor. This SPCC Plan will outline specific measures to be taken to prevent the release or spread of discharged materials including those materials the contractor may store, use, or generate during construction activities. These items include, but are not limited to, gasoline, oils, and chemicals. 4. Plants a. Check or circle types of vegetation found on the site: deciduous tree: alder, maple, aspen, other evergreen tree: fir, cedar, pine, other shrubs grass pasture crop or grain wet soil plants. cattail, buttercup, bullrush, slunk cabbage, other X water plants. water lily, eelgrass, milfoil, other other types of vegetation b. What kind and amount of vegetation will be removed or altered? 10 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY A December 2006 dive survey of the immediate area noted minimal aquatic vegetation. If there are any aquatic plants within the dry docks deconstruction area they may be inadvertently removed during the deconstruction work as the surrounding sediment will likely be disturbed. c. List threatened or endangered species known to be on or near the site. There are no known threatened or endangered plant species at or near the project site. d. Proposed landscaping, use of native plants, or other measures to preserve or enhance vegetation on the site, if any: No planting is proposed. The project occurs below Lake Washington's ordinary high water mark and on sediment slated for a CERCLA cleanup. 5. Animals a. Circle any birds and animals which have been observed on or near the site or are known to be on or near the site: birds: hawk, heron, eagle, songbirds, other: mammals: deer, bear, elk, beaver, other: fish: bass, salmon, trout, herring, shellfish, other: Birds observed on or near the project site include hawks, herons, eagles, songbirds, osprey, cormorant, and domestic quail. Fish observed on or near the project site include bass, salmon, trout, longfin smelt, threespine stickleback, freshwater shrimp, northern pike minnow, prickly sculpin, black crappie, bluegill, pumpkinseed sunfish, tench, and yellow perch. b. List any threatened or endangered species known to be on or near the site. Puget Sound steelhead trout, Puget Sound Chinook salmon, and Coastal/Puget Sound bull trout. c. Is the site part of a migration route? if so, explain. This site is part of the Pacific Flyway, a major north -south seasonal migration route for many bird species. This site is also used as a migratory corridor and provides rearing habitat for Puget Sound Chinook salmon and Puget Sound steelhead trout. Lake Washington may also provide foraging habitat for CoastaVPuget Sound bull trout and contains the largest population of naturally occurring sockeye salmon in Washington State. Most spawning and fry production occurs in the Cedar River, located several miles south of the project site. d. Proposed measures to preserve or enhance wildlife, if any: This project will remove the two wood dry docks from Lake Washington that currently provide cover, shade, and focal points for predators of juvenile salmon. During deconstruction of the dry docks, BMPs will be implemented to control turbidity and protect water quality (Refer to Section B.1.h for additional information). Additionally, all work will occur in accordance with allowed fish windows and bird nesting and migration windows as determined by WDFW. A biological evaluation of the project site is also in preparation for consultation with NMFS and USFWS I TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY that addresses ESA -listed species in Lake Washington. 6.

No, this project would not affect the potential use of solar energy by adjacent properties. c. What kinds of energy conservation features are included in the plans of this proposal? List other proposed measures to reduce or control energy impacts, if any: None, not applicable. 7. Environmental health a. Are there any environmental health hazards, including exposure to toxic chemicals, risk of fire and explosion, spill, or hazardous waste, that could occur as a result of this proposal? If so, describe. As noted earlier, the state-owned aquatic lands on which the dry docks are located are part of the Quendall Terminals Superfund site. While the most extensive contamination on the Quendall Terminals Superfund site is located along the shoreline and in the uplands portion of the Quendall Terminals parcel, there is some contaminated sediment present where the dry docks are currently sunk that is associated with historical creosote manufacturing transfer operations. As part of the former creosote manufacturing facility, a T-Dock was constructed and used to transfer tar feedstock from tankers and barges from Lake Washington to the upland operational areas. The dry docks are sunk just to the north of where the T-Dock transfer operations occurred and contamination at this end of the T-Dock area is assumed to have come from coal -tar spills during historical operations. Polycyclic aromatic hydrocarbons (PAHs) are the primary components of coal tar and creosote and have been identified at elevated concentrations in sediment in the vicinity of the dry docks (and the historic T-Dock spill area). Only one surface sediment sample (0 to 10 cm below the mud line) in the vicinity of the dry docks had total PAHs exceeding the Quendall Terminals site specific screening level for total PAHs of 100 mg/kg. This surface sediment sample had a total PAH concentration of 458 mg/kg. There were several exceedances of the total PAH screening level in subsurface sediment samples collected in this dry dock area (10 to 20 cm below the mud line) with sediment concentrations ranging from 325 to 1,592 mg/kg. Several subsurface sediment concentrations of naphthalene, a PAH, exceeded the Washington State Department of Ecology (2003) Freshwater Sediment Quality Screening Value for naphthalene of 529 ug/kg in the vicinity of the dry docks; however, no surface sediment samples (0 to 10 cm below the mud line) had exceedances. The subsurface samples with naphthalene exceedances were observed at depths of 10 to 30 cm below the mud line with concentrations up to 3,300 mg/kg. Dense non -aqueous phase liquid (DNAPL) has also been observed in the sediment in this area at depths from 0 to 5 feet below the mud line. Further information on sediment contamination in the T-Dock spill area is presented in the Draft Task 3 Preliminary Conceptual Site Model, Remedial Action Objectives, Remediation Goals, and Data Gaps, Remedial 12 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY Investigation/Feasibility Study for the Quendall Terminals Site prepared by Anchor Environmental and Aspect Consulting (November 2007). During the deconstruction of the dry docks, contaminated sediment below and in the vicinity of the dry docks will be disturbed and this sediment will suspended into the water column. There is also the potential that DNAPL present in the sediment will be released into the water column, causing a sheen on the water surface. Refer to Section 7.a.2 below for mitigation measures that will be taken to control these environmental health hazards. As previously discussed in Section 3.a.6, typical hazardous materials that may be contained in or on wood dry dock structures are asbestos -containing caulking, chinking, and wire coating, sand blast grit embedded in the wood decking and wingwalls, and marine paint containing toxic compounds such as polychlorinated biphenols (PCBs), lead, other heavy metals and TBT. Based on visual inspections of the two Lake Washington dry docks, there are unlikely to be significant quantities of these hazardous materials are present on or within these structures. A formal hazardous materials survey will be completed prior to deconstruction of the Lake Washington docks to determine if these hazardous materials are present and approximate quantities. These materials will be removed with the wood deconstruction debris as the dry dock structures are cut into pieces and placed into a disposal barge. As part of this survey work, sediment sampling will also be performed in the hull chambers of the dry docks to determine if sand blast grit is present within the hull and if this sediment should be removed prior to the deconstruction work. 1) Describe special emergency services that might be required. No need for special emergency services is expected. 2) Proposed measures to reduce or control environmental health hazards, if any: Please refer to Section B.1.h above, as many of the measures that will be implemented to reduce or control any environmental health hazards resulting from the project have already been listed in this earlier section. The mitigation measures listed in this earlier section will address containing and handling any contaminated suspended sediment and dry dock debris with potentially hazardous materials associated with the removal of the dry docks, along with water quality monitoring and sampling. If results of the hazardous materials survey indicate that asbestos -containing materials are present on the dry docks or if there is marine paint on the dry docks or sand blast grit embedded in the wood of the dry docks, these materials can still be considered manageable as deconstruction debris as they would be removed from the project site with the wood deconstruction debris. If the sediment within the hulls shows a predominance of sand blast grit, then this sediment will be removed from the hulls prior to the deconstruction work. Once the two wood dry docks are deconstructed, a sweep of the sediment surface will be completed to remove potential residual debris from the sediment surface. Contaminated sediment within the project area will be addressed as part of the Quendall Terminals Superfund site and will not be removed as part of this project. Any sediment suspended during the deconstruction work will be allowed to settle out and return to the sediment surface. If any DNAPL is stirred up and released into the water column as a result of this project, sorbent booms or other sorbent materials will be used to capture the DNAPL. One of the benefits of removing the dry docks from these contaminated sediments is that it allows additional investigation and cleanup of the sediments by the Quendall Terminal potentially responsible parties under CERCLA. The project would be accomplished in accordance with a site -specific health and safety plan, to ensure 13 TO BE COMPLETED BY APPLICANT EVALUATION FOR AGENCY USE ONLY that construction personnel who may encounter contaminated media are appropriately trained, prepared, and outfitted, and that management of contaminated media is conducted in accordance with relevant local, state and federal requirements. As mentioned previously in Section B.3.d, a Spill Prevention, Control, and Countermeasures (SPCC) Plan will also be developed for the project by the selected contractor. b. Noise 1) What types of noise exist in the area which may affect your project (for example: traffic, equipment, operation, other)? No noise in the area is expected to affect this project. 2) What types and levels of noise would be created by or associated with the project on a short-term or a long-term basis (for example: traffic, construction, operation, other)? Indi- cate what hours noise would come from the site. Short-term noise would be generated at the project site by heavy equipment during the deconstruction of the dry docks and the loading of the dry dock debris into barges. There would also be noise associated with generators and pumps on board the barges necessary to operate this heavy equipment and barges. This heavy equipment operational noise would generally occur during normal working hours (Monday through Friday, 7 AM to 6 PM) during the removal of the dry docks. There is no long-term noise associated with this project. 3) Proposed measures to reduce or control noise impacts, if any: Deconstruction and loading of the dry docks into barges by heavy equipment would be limited to normal working hours. These construction activities would comply with applicable state and local noise regulations. No other unusual noise impacts are expected to occur that would need further control measures. S. Land and shoreline use a. What is the current use of the site and adjacent properties? The project site is on state-owned aquatic land within Lake Washington that is designated as a harbor area and is managed by WDNR.
