All changes will be reviewed and approved by the airport operator and the FAA. c. FAA Coordination. The project will be coordinated with Peter Doyle, Seattle Airports District Office (ADO) project manager in conjunction with submittal of FAA form 7460 -1. The project will be coordinated with Renton Airport Traffic Control Tower (ATCT) manager. 206. Phasing. The sequence of construction has been phased to gain maximum efficiency while allowing minimizing impacts to normal operations. The construction phases have been coordinated with airport users. The general phasing strategy has been to incorporate the majority of the dredging activity during periods of temporary closure of Runway End 16. Closure will include approach to Runway 16 as well as departure from Runway 34. This will eliminate construction interference with regulated airspace concurrent with the dredging operation in the bay. Typically this closure will occur during the hours (1200 — 2200), but the Airport reserves the right to extend the closure into day time on a case by case basis. See construction drawings for more information related to the Runway End 16 partial closure. a. Phase Elements. Refer to the construction drawings for: • Areas closed to aircraft operations • Taxi routes • Construction staging areas • Construction access and haul routes • Impacts to NAVAIDs • Lighting and marking changes Renton Municipal Airport Will Rogers -Wiley Post Memorial Seaplane Maintenance Dredging Project Construction Safety and Phasing Plan • Available runway length • Declared distances • Hazard marking and lighting • Lead times for required notifications b. Construction Phase Drawings. Drawings have been developed which indicate the specific safety procedures, and construction crane height restrictions. Available declared distances are shown in both the CSPP as well as the construction drawings. 207. Areas and Operations Affected by Construction Activity. The construction phasing plan has been developed to allow runways and taxiways to remain in use to the maximum extent possible without compromising safety. The plan was discussed with airport users during project design.

Navigation Aid (NAVAID) Protection. This project will be coordinated with the FAA ATO /Technical Operations office through submittal of FAA form 7460 -1. During construction the use of cranes up to 40 feet tall will cause major changes in the use of the airport. A temporary closure of Runway End 16 operations will be used to avoid conflict with approach /departure surfaces over the construction equipment. When Runway End 16 is out of service for approach and when Runway End 34 is out of service for departure, certain NAVAIDS will be out of service and all traffic will operate under visual flight rules. (See plan sheet C -S for Declared Distances associated with partial runway closure operational conditions.) When operations are in standard conditions, traffic will operate normally and contractor personnel may not enter critical airport areas. Access to these areas shall be clearly marked as shown in the contract documents. The contractor will initiate the appropriate submittal to Airport Operations for all NOTAMs during construction activities. (See 213. b below for more information regarding NOTAMs.) 209. Contractor Access. The project drawings show the areas to which the contractor has access, and how contractor personnel will access those areas. Specifically addressed are: a. Location of Stockpiled Construction Materials. Stockpiled materials and equipment storage are not permitted within the RSA, OFZ or OFA of an operational runway. Stockpiled materials and equipment adjacent to these areas shall be prominently marked and lighted during hours of restricted visibility or darkness.

Accidents between ground vehicles and aircraft occur at airports around the world. To reduce accidents and liability, the Renton Airport has developed this Ground Vehicle Operations Handbook to educate drivers on the safe operation of vehicles in the Aircraft Operations Area. Please keep this manual readily available and use it as a reference guide. Questions or clarifications about airport operations are always welcome. Please feel free to stop by the Airport Office at the base of the Air Traffic Control Tower during our normal business hours or call us at (425) 430.7471. By following the procedures outlined in this book you are helping to create a safer and more enjoyable environment for all users of the Renton Airport. �1_ AIRPORT RENTON { HOME OF AMERICAS FIRST JET AIRLINER WI& THE ROGERS POST MEMORIAL SEAPLANE BASE 5480 FT CONCRETE RUNWAY- ELEVATION 32 FT.- BEACHING RAMP RADIO 6 LIGHT SIGNAL CONTROL TOWER • OPERATION 0900-1700 DAILY •; °,:; { MAGNETIC HEADINGS 330'& ISO' • LOW INTENSITY NIGHT RUNWAY LIGHTS - SEAPLANE TIE-DOWNS CHARTER FLIGHTS• AIRCRAFT RENTALS• AIRCRAFT ENGINE REPAIR FLIGHT INSTRUCTION - RESTAURANT SNACK BAR -AIRCRAFT SALES & SERVICE, DAY CITY OF I n/IGHT OL•3464 LLI+�o►l OL• 3467 3 �r Purpose and Objectives The purpose of the ground vehicle training program is to promote safe airfield driving through education. The program provides new and refresher training for employees, tenants, and other ground vehicles operators on this airfield. The primary objectives of this program are to: • Introduce and explain the procedures specific to Renton Airport for operating ground vehicles; • Identify and describe movement areas, non - movement areas, runways, and taxiways; • Identify and describe airfield signs, markings, and lighting at Renton Airport; • Identify and describe the Vehicle Drive Lane and the runway hold short lines; • Describe the appropriate radio procedures while operating within the Movement Areas; and • Provide other useful Airport- specific information. 4 General Airport Areas Specific terms are used to describe certain areas on the airport. You must be familiar with these terms to know what requirements you must meet to enter and operate in these areas. Landside and Airside The airport is divided into two general areas termed landside and airside. The landside area is the area of the airport that is outside of the security fence and is open to the general public. The airside, which is also referred to as the Air Operations Area encompasses all areas within the security fence and is not open to the general public. Landside Both perimeter roads, parking lots outside of the security fence, the front entrance garden and statue area, and the grassy area at the north end of the Airport are on the landside. Landside vehicle operators do not need to communicate with the Control Tower, nor are landside vehicles required to have a flashing amber beacon. Airside All areas inside of the perimeter security fence are on the airside also known as the Air Operations Area, or AOA. These areas include parking areas, aprons, taxilanes, taxiways, and the runway. The AOA is further divided into Non - Movement and Movement Areas. Airside - Non - Movement Areas The non - movement area consists of the areas on the Airport that are in the AOA but neither require you to be in contact with the Control Tower, nor have a flashing amber beacon (designated airport vehicles excluded — see page 19). Non - movement areas include parking areas within the security fence, and the aprons. General Airport Areas - Continued Airside - Movement Areas The runway, taxiways, and the taxiway object free area are the only Movement Areas on the Airport. The Control Tower controls all movement areas on the airport. Hence, any operation in a Movement Area requires authorization from the Control Tower. The Control Tower transmits on two frequencies, Tower (124.7 MHz) and Ground (121.6 MHz). Operating a vehicle in the Movement Areas requires authorization from the Control Tower, when open, and use of a flashing amber beacon. At all times when the Control Tower is closed, intentions must be communicated over the Common Traffic Advisory Frequency (Same as the Tower Frequency - 124.7 MHz). To operate a vehicle in the movement area you must have a flashing amber beacon mounted on the uppermost part of your vehicle and be in contact with the Control Tower. Use of Control Tower Frequencies While operating on most areas of the Airport, you will use the Ground frequency. There are some areas on the Airport that require use of the Tower frequency. The list below should help clarify which frequency to use during a particular operation. If you are: • Operating only on a taxiway - use the Ground frequency (121.6 MHz); • Crossing the runway from taxiway to taxiway - use the Ground frequency (121.6 MHz — Airport employees only); • Entering the runway for inspections or maintenance - use the Tower frequency (124.7 MHz - Airport employees only); • Using the east access road to the north bridge - use the Tower frequency (124.7 MHz - Airport employees only); and • Crossing the runway from the Alpha Taxiway to the north bridge - use the Ground frequency (121.6 MHz —Airport employees only). In general, aircraft get to and from aprons and runways via taxiways. Taxiways have yellow markings and blue edge lights. Each taxiway is labeled with a letter and those letters are part of a phonetic alphabet. Meaning, instead of being referred to as Taxiway "A," the taxiway would be referred to as Taxiway Alpha. Clearance must be obtained from the Control Tower prior to entering the Taxiway Object Free Area. Think of it this way, if you are on the west side of the airport stay west of the yellow line, ' and if you are on the east side of the airport stay east of the yellow line. t 7 Taxiway Markings and Lighting — Continued Taxiway direction and designation signs have a yellow background with black lettering. These signs indicate where that taxiway is located from your present position. A taxiway location sign has a black background with yellow lettering. This sign identifies the taxiway you are presently operating on. Taxiway and runway identification signs may be used together to provide directional information to the pilot or driver. For example, this sign indicates you are currently at the Echo intersection of Taxiway Alpha facing Runway 16 -34. 8 Runway Markings and Lighting Runway Paint Markings Runway markings are white. Runways have numbers on each end and a broken white stripe down the center. The numbers on each end of the runway identify the magnetic heading of the runway. By adding a zero to the runway number you will know its compass heading. For example, Runway 16 equates to approximately 160 °. Note that at the other end of the runway the number is 34 (340 °), which is 180° in the opposite direction of Runway 16. Runway Lighting Runways have white lights along the pavement edges. The exception is that the edge lights on the last 2000 feet of the runway are white on one side of the light cover and amber on the other (Runway 16 only). Runway threshold lights are additional lights that are positioned across the ends of each runway to indicate where the runway begins or ends. These lights are green on one side of the light cover and red on the other. 11 Runway Markings and Lighting - Continued Runway Hold Line A Runway Hold Line denotes where the taxiway ends and the runway begins. It consists of two solid yellow stripes followed by two broken yellow stripes. If you come to a runway hold line — STOP! Only Airport employees are permitted to cross the runway. All other ground vehicles must use the perimeter road to access the other side of the airfield. Airport employees must receive clearance from the Control Tower before proceeding onto the runway when the Control Tower is open. If the Control Tower is closed, you must: • Wait for any aircraft in the pattern to land and exit the runway prior to proceeding; • Ensure that your movement onto the runway will not interfere with aircraft taxiing, landing, or taking off; and • Make a radio announcement of your intentions to cross the Runway Hold Line onto the runway. Announcements should be made on 124.7 MHz when the Tower is closed. 10 t I t t t t 1 t Vehicle Restricted Areas Vehicle Restricted Areas have been established at the Airport to provide increased security for the Boeing Company's leased aprons, and also to decrease runway and taxiway incursions (unauthorized entry onto a taxiway or the runway). Vehicle Restricted Areas are marked with stop signs. If you come to one of these signs - STOP! There are three restricted areas. The first is located north of the last row of hangars at the end of East Perimeter Road. This access road is for airport operations and maintenance vehicles only. The second restricted area is Taxiway Bravo from the compass pad south to the large Aerodyne hangar located at 300 Airport Way. This area is off limits for all non - Boeing vehicles. Float trucks and airport operations and maintenance vehicles may proceed on Taxiway Bravo when authorized by the Control Tower. The third restricted area is Taxiway Alpha from the Lane Hangars at 500 West Perimeter Road south to the large hangar at 243 West Perimeter Road. This area is off limits for all non - Boeing vehicles. Float trucks and airport operations and maintenance vehicles may proceed on Taxiway Alpha when authorized by the Control Tower. Any unauthorized drivers caught driving in the Vehicle Restricted Areas will have their access privileges revoked by the Airport Manager or his /her designee. NOT PROCEED F___7DO THOUT CLEARANCE Vehicle Restricted Areas Map t t i t H 11 t d 12 1 Vehicle Drive Lane The Vehicle Drive Lane runs most of the length of the airfield on the west side. The Vehicle Drive Lane is the designated drive lane for private vehicles operating on the airport. Vehicle traffic must use the Vehicle Drive Lane where it exists. Where the Vehicle Drive Lane is not yet present, or if portions of the lane are blocked, vehicle traffic must stay as far away from the Taxiway Object Free Area as reasonably possible. Be cautious while using the Vehicle Drive Lane around Lane Hangars and the 540 Hangar. Also, be alert for aircraft crossing the Vehicle Drive Lane to enter the taxiway. No vehicle may pass in front of an aircraft that is positioned on the ramp waiting to taxi, unless that pilot signals that it is alright to pass. All aircraft have the right -of -way over vehicles (Advisory Circular 150/5210 -20). If you see an aircraft that appears poised to taxi across the ramp, you must wait for that aircraft before continuing to your destination. 13 Renton Air Traffic Control Tower When open, the Control Tower directs all vehicle traffic on the movement area. The Control Tower is open every day of the year. Hours of operation are 7:00 am to 8:00 pm from October 1 to April 30, and 7:00 am to 9:00 pm from May 1 to September 30. When the Control Tower is closed, there are different requirements for communicating your intentions while driving on the movement area. Radio Communications — Tower Open When the Control Tower is open you must contact Tower or Ground for approval prior to moving aircraft or vehicles onto a movement area. You will need to use different frequencies to receive authorization from the Tower depending on where you will be driving. 14 Renton Air Traffic Control Tower - Continued tRadio Communications — Tower Closed t 1 Ij k When the Control Tower is closed, the airport becomes an uncontrolled field. The procedure during these hours is to monitor the Common Traffic Advisory Frequency on 124.7 MHz and announce your intentions to enter any movement area. You must announce your intentions prior to entering the movement areas and upon exiting the movement areas. When the Renton Air Traffic Control Tower is closed, vehicle operators must monitor the Common Traffic Advisory Frequency (124.7 MHz) and make an announcement prior to entering the movement areas and upon exiting the movement areas. 15 Rules for Radio Communications The following are requirements for radio communications while operating a vehicle in the movement area. Make Sure To: • Transmit on the appropriate frequency; • Listen to the frequency prior to transmitting; • Use appropriate radio phraseology; • Use standard vehicle identification phrases; • Advise on initial contact your request — who you are calling (Renton Ground or Tower), who you are, where you are, and what you want to do; and • Be familiar with the locations of the movement and non - movement areas. 16 1 Loss of Radio Communications Non- Movement Areas If you are only operating in the non - movement area then two -way radio contact with the Control Tower is not necessary. If you have a radio installed in your vehicle and it becomes ' inoperable you may continue to operate in the non - movement area only. I t t Movement Areas If your radio becomes inoperable before you proceed into the movement area then do not continue. Instead, return the vehicle for radio repairs. If you are on the movement area and lose radio contact with the Control Tower, you should do the following: • Get off the movement area immediately! • Turn your vehicle toward the Control Tower and flash your headlights. • Look up at the Control Tower cab for light gun signals. • If the Control Tower responds with a steady red signal you must STOP! • If the Control Tower responds with a steady green signal you may proceed. If you have a cell phone, you may call the Control Tower at 206 - 764 -6632 for instructions as on alternative. 17 Light Gun Signals Color and Type of Movement of Vehicles, Equipment, and Light Signal Personnel Steady Cleared to Cross, Proceed Steady Red STOP! Flashing Red Clear the Taxiway or Runway Flashing White Return to Starting Point Alternating Green and Red Exercise Extreme Caution Stop! 18 Proceed 1 F ,—J C I 1 t t �I I I Driving on the Airport Personal Vehicles on the Airside Personal vehicles not equipped with an amber beacon or a two -way radio are only allowed to operate in the non - movement areas (designated Airport vehicles excluded). Use of the Vehicle Drive Lane is required where it exists to ensure proper separation from airplanes and other vehicles. Be cautious. Look around for airplanes that are preparing to start or that are beginning to taxi. Always yield to aircraft by moving right where able. Airport Vehicles on the Airside Designated airport vehicles include float trucks, fuel trucks, airport or Boeing maintenance trucks, Boeing tugs, Boeing service vehicles, fire vehicles, and airport management vehicles. All designated airport vehicles must use an amber beacon while operating in the AOA. Designated airport vehicles are required to have fully functional radios, and operable lights (including parking lights, headlights, and taillights). All designated airport vehicles must use the Vehicle Drive Lane where it exists except in cases where doing so could harm people, parked aircraft, or vehicles. Fire vehicles, Boeing fuel trucks, and float trucks may deviate from the Vehicle Drive Lane as needed for added safety. 19 Foreign Object Debris is any loose item in an airport environment that could be ingested by aircraft engines or could strike an airplane and create damage. Foreign Object Damage is defined as aircraft engine damage due to ingestion of objects and /or debris. Jet engines ingest huge amounts of air. Garbage and debris can also be sucked into the engine causing extensive damage. Debris can also puncture tires and dent or puncture propellers or wings. Nuts and bolts, tools, rocks and pebbles, or any garbage can be classified as or cause FOD. Make Renton Airport a safer place by placing all garbage in a sturdy, covered container that cannot be blown over by wind or jet blast. Also, please pick up any debris you find on the ground. Finally, avoid tracking mud and gravel onto pavement surfaces. If you must drive on an unpaved surface, stop your vehicle and check your tires once you leave that area. Remove any rocks that are lodged in the treads. If you discover a serious debris problem, report it to the Airport Office at (425) 430.7471. 20 Other Airport Information Float Truck Operations When retrieving floatplanes from the floatplane ramp, back up towards the west to avoid entering the Runway Safety Zone for Runway 16. Accident Reporting Any person involved in an accident, as a participant or as a witness, shall report the accident immediately to the Renton Police and /or Renton Fire and Emergency Services via 911. You must also notify airport management at (425) 430.7471. Dial 911 and (425) 430.7471 to report all emergencies, accidents, hazardous material releases, and fuel spills. Watch Your Speed The speed limit on the ramp is 15 MPH except while driving near aircraft when the speed limit decreases to 5 MPH. No Unattended Vehicles No disabled vehicle may be left unattended or abandoned in the AOA. If your vehicle breaks down, you must remain with it and call for assistance. 21 Other Airport Information (Continued) Use a Ground Guide When backing trucks or equipment in close proximity to other equipment, aircraft, or vehicles, a ground guide is strongly recommended. Use Parking Brake and /or Wheel Chocks If you must park a vehicle in the AOA, you must always set the parking brake or use wheel chocks to prevent the vehicle from rolling into aircraft or other equipment. Be Aware of Jet Blast and Prop Wash You should be aware of the effects of jet blast and prop wash. An operating jet engine can easily produce a blast of hot air strong enough to knock you to the ground or burn you. There have been several documented cases where vehicles have been overturned by jet blast. Prop wash can also knock you down or throw debris in your face. Therefore, remain clear of areas behind operating jet or propeller engines. 22 Other Airport Information — Continued Reporting Hazardous Material Spills If a hazardous material release occurs, you must contact Renton Fire and Emergency Services via 911, and the airport office at (425) 430.7471. Avoid Blind Spots Blind spots are areas on the Air Operations Area that are not visible from the Air Traffic Control Tower. Use extreme caution when operating in these areas and always yield to aircraft. These areas include: • The area near the Ace Aviation and Aerodyne buildings; • The area next to the City Hangar (south of the Tower); • The area between the Northwest Seaplanes hangar and the hangar building at 850 West Perimeter Road; and • The areas between the Lane Hangars. ® Renton History Museum. All rights reserved. 23 Other Airport • • n — Continued Low Visibility Driving It is extremely easy to become disoriented when driving on the airfield in rain, fog, or at night. Drive slowly and watch for signs and markings. If you are unfamiliar with the airport and the office is open, stop in and ask for directions to your destination. If the airport office is closed, drive with someone who is very familiar with the layout of the airport. While driving on the airport: • Give yourself plenty of time to get to your destination; • Make sure the vehicle's amber beacon is operating properly; • Make sure your radio is operating properly and the volume is up; and • Remember that the maximum permissible speed is 15 MPH or 5 MPH if you are near aircraft. 24 t 1 t Appendix 1- Phonetic Alphabet Always use the International Phonetic Alphabet when communicating with the Control Tower.

INTRODUCTION The Bryn Mawr Trunk Siphon is located in Renton at the south end of Lake Washington. The inlet structure is located near the old treatment plant location, northwest of the airport near South 113th St. The outlet structure is located in Cedar Creek Park northeast of the airport. The siphon consists of three barrels of 24 inch, 16 inch transitioning to 14 inch, and 10 inch transitioning to 8 inch. The two smaller diameter siphons were surveyed in this program. The siphons are constructed of cast iron pipe with a nominal length of 1590 feet. The siphons are accessed from inlet vault RO1 -43B and outlet vault RO1 -43. The surveys were carried out in good weather and flow conditions on the 21 st and 22nd of October, 2009. The sonar system employed is a compact 2.2 MHz rotating head unit. The unit includes a roll ' and pitch system which was used to provide tool orientation. The sonar system was pulled through the pipe by means of a winch located at the siphon inlet. Communication with the sonar unit was carried out via an umbilical cable operated from a winch system located at the siphon outlet. A cable payout counter recorded the probe position as the sonar instrument was moved through the trunk, and load cells were used to monitor the amount of strain on each cable. 2. SCOPE OF WORK The project entailed carrying out a sonar profiling inspection of the Bryn Mawr Trunk Siphon. The purpose of the inspection was to assess the condition of the pipe, to ascertain the level of sediment or other obstruction in the pipes, and to provide a benchmark to plan the remediation program. The survey presented a number of challenges including very small diameter pipes (8 inch), significant bends in the pipe, and transitions between pipe diameters. 3. SURVEY METHODOLOGY 3.1 Instrumentation and Survey Operation ' The probe instrumentation acquired sonar data in real time and transmitted this data to the operations trailer through an umbilical cable. The probe instrumentation was contained within a high pressure, water tight housing. Power for the electronics was transmitted on copper conductors incorporated into the umbilical cable. Other telemetry information relayed back to the operations trailer included cable tension, system attitude, and temperature and voltages in the probe. The data was displayed on color graphics displays for real time monitoring and stored on hard disk in the operations trailer. A 2.2 MHz Marine Electronics Model 2512 scanning narrow -beam profiling sonar was used on the survey. The sonar generates a narrow cone of acoustic pulses that are transmitted through the water. Once the pulse hits a target, it bounces back and the echo appears as a data point. Settings for the sonar operation, based on local site conditions, are entered in the control software. Through the use of subsequent processing software, this data is translated into XYZ positions and can be plotted in a variety of formats. Frontier Geosciences Inc. d r LAKE WASHINGTON R01 -4413 I �• C! it n A cable winch and take up equipment driven by a variable speed electrical /hydraulic motor /gearbox system which can develop tensions of up to 1000 pounds, was used as the draw works for the survey. The cable is terminated into a rotary slip ring assembly. A payout device located at the winch station was used to measure the amount of umbilical cable deployed to high precision. This device also incorporates a load cell to measure the force on the cable system. These signals are relayed via a cable to the operations trailer displays. The operations trailer for the Bryn Mawr Trunk Siphon command was located along the side of the road on the Cedar Creek Park access road near the vault manhole. Sonar Solutions personnel rigged a manhole sheave wheel and downhole cable turning shoe to direct the umbilical cable into each of the siphon barrels. Photo 1, Bryn Mawr Siphon outlet access MH R01 -43 showing Boeing Plant in background The umbilical cable was then seated in the payout counter and load cell system, engaged with the hydraulic tugger, and the probe was lowered into the shaft. The survey was commenced after the payout zero for the sonar head position was established, and all recording software was operating. The pull through operations were initiated by the Sonar Solutions crew by sending a drogue through the 16 -14 inch pipe. Once the drogue was recovered from the outlet end of the pipe, the tow line was attached to the sonar sonde. The tow cable winch was driven by a variable speed hydraulic tugger and winch system. Frontier Geosciences Inc. Photo 2, Tow line drawworks setup at siphon inlet (photo: Dale Wenzel) The probe was then launched, controlled by the umbilical cable upstream, and the inspection operation was underway. The tow line winch was operated at a constant torque, and the umbilical cable winch was run at a constant. speed resulting in the slow, smooth progress through the pipe required to obtain high quality cross sectional data. The run was completed when a marker flag on the rope emerged from the south vault, and the projected measured distance had elapsed. The process was then reversed and the probe recovered at the umbilical cable end of the inspected section of pipe. The process was then repeated to survey the 10 -8 inch barrel. As there was very little flow in the 16 -14 inch barrel on the day of the survey, Sonar Solutions personnel temporarily obstructed the 10 -8 inch barrel in order to provide sufficient flows to operate the drogue. No flow control was required for operations in the 10 -8 pipe. Frontier Geosciences Inc, [I 0 3.2 Data Processing The sonar data was processed in a number of stages. The first stage consisted of picking a reflection horizon from the sonar data file. An algorithm with a variable threshold and exclusion filter was used to define the pick distance, and the main reflection was selected. A discrete chainage value for each sonar ping was determined by performing a time -based interpolation between the points of the payout data records. Data from the pitch and roll sensors were then interpolated into the positional array from the ping data. The wall reflections were rotated back to a normal plane to correct for probe rotation in the pipe. The data was then analyzed to determine the distance between the sonar, the side walls, and crown of the pipe. By combining this with data from the tilt sensors, horizontal and vertical displacements for the sonar could be calculated for each data point. A spline fit through the displacements created a probe path curve, and the XY position of each point was then shifted so that the sonar was reduced to the equivalent of pipe center. The data was then ready to be processed to allow cross - sectional drawings. As well, detailed measurements of percent area relative to an ideal pipe were calculated. Processing of Sonar Determined Pipe Radii Frontier Geosciences Inc. 6 4. SURVEY RESULTS The processed sonar data for the Bryn Mawr Trunk Siphon was plotted in cross - section format at a scale of 1 inch = 1 foot on Drawings BM14 -SEC -1 to BM14 -SEC -6 for the 16 -14 inch barrel and 1 inch = 8 inches on Drawings BM8 -SEC -1 to BM8 -SEC -6 for the 10 -8 inch barrel. The cross - sections are keyed to the station numbers defined on the 1962 Bryn Mawr Trunk Siphon drawings. The cross - sections are plotted looking downstream. The observed data are displayed as a red line, with a black circle indicating the nominal pipe section for comparison. These cross - sections include an estimate of the. percent pipe obstruction, as compared to the nominal ideal pipe diameter. The outlet segment of the 16 -14 pipe was partially charged for the first 185 feet. The 8 inch pipe barrel was found to be generally clear of sediments and no evidence of FOG (fats, oil and grease) was present on the crown. An example of the generally clear 8 inch pipe is shown in the sonogram below. In these images the probe position appears as a circular object near the pipe invert. Distance: 265.5 feet The dominant feature in the pipe is an approximately 20 foot steeply inclined segment near the south shore of Lake Washington. A small amount of sediment is present immediately upstream of this segment, but this does not present a significant obstruction: The sediment is seen in cross - section format in Dwg. BM14 -SEC -1 at a distance of 210 feet. The following sonogram shows the presence of the sediment in the pipe invert: Frontier Geosciences Inc. 1 F i _I Distance: The 8 inch pipe transitions to 10 inches over length at a chainage of 1490 feet. No sedir location. The 14 inch pipe is generally clear of obstructi length. An example of the generally clear 14 in 210 feet t transition coupling of approximately 1 foot nentation or other effects were seen at this )ns and debris throughout the entire surveyed �h pipe is shown in the sonogram below: Distance: 1290 feet Frontier Geosciences Inc. An approximately 30 foot section of pipe between 1230 and 1260 was found to have a small amount of gases in the crown. This location corresponds to a local high in the pipe elevation which acts as a trap for the gases. The obstruction effect of this is small, reaching a maximum of 6.6% at this location. An example of the pipe with trapped gases in the crown is shown in the sonogram below: Distance: 1250 feet The orientation of the sonde is determined at all points in the pipe by means of detailed measurements of pitch and roll. The pitch, or inclinometer, measurement provides a means to monitor the elevation changes encountered by the sonde, by integrating the inclination of the sonde, together with chainage, along the length of the pipe. In the case of the Bryn Mawr Siphon this produces an elevation diagram that can be compared with the `as- built' information on the 1962 Bryn Mawr Trunk Siphon drawings. The plots are generally in agreement between the two data -sets, and clearly show the steep riser segment of the siphons at the southern shore of Lake Washington. There is one notable departure from 1962 `as- built', at station 5450. This appears as an approximately 7 foot vertical, local elevation low at this point. This is likely an undocumented elevation variation in the construction of the pipe, rather than a result of soils or pipe movement. It is of value, however, to identify this anomaly for comparison with future surveys of the structure. This information is plotted on the Longitudinal Section BM- LONG -1, which shows the 1962 `as- built' profile together with the profile produced by processing the sonar sonde inclinometer data.

LIMITATIONS The distance to a given tunnel surface may be determined accurately based on the acoustic travel times, based on a water velocity that is dependent on water temperature and salinity. An underestimate of the velocity function would produce distances that are too close, and the reverse occurring with an overestimate of velocity. Some errors may also occur in gridding between interpreted data. The nature and composition of features identified in sonar surveys cannot be absolutely determined by inspection of the data. Several indicators such as reflector strength, diffraction patterns, position, smoothness of reflectors and reflector relief may provide insight into composition. The information in this report is based upon sonar measurements, field procedures, and our interpretation of the data. The information is based upon our estimate of conditions considering the geophysical and all other information available to us. The results are interpretative in nature and are considered to be a reasonably accurate presentation of the pipe conditions, within the limitations of the methodology employed.

A Dredged Material Management Program suitability determination was issued on April 10, 2007, covering 16,000 cubic yards of proposed dredged material (DMMP, 2007). The entire volume was found suitable for open -water disposal or beneficial use in a marine or freshwater environment. Being in a moderate - ranked area, a 5 -year recency period was provided in the suitability determination, ending in April 2012. 2. On March 22, 2012 the City of Renton requested an extension of the recency period to February 2014 (Attachment 1). 3. There have been no known spill events or changed conditions in the project area since the original suitability determination was issued. The DMMP agencies were consulted and are in agreement that extension of the recency period to the end of the dredging window in February 2014 is acceptable. This recency extension is contingent upon there being no significant changes in the sediment quality at the project site between the date of this memorandum and the time of dredging. 4. The City of Renton also notified the Dredged Material Management Office of minor modifications to the dredge prism (see the figures in Attachment 1). The proposed dredge depth has been changed from +7 feet to +8 feet (Corps of Engineers Lake Washington Datum). The footprint has also been modified, having been shifted to the west and expanded to the south to include the area occupied by the floating docks. These modifications did not alter the total project volume, which remains at 16,000 cubic yards. The DMMP agencies reviewed the proposed depth and footprint changes and determined that the sampling and testing completed in 2006 still adequately represent the modified project. 1 5. A pre- dredge meeting with DNR and the Corps of Engineers is still required. A dredging quality control plan must be developed and submitted to the Seattle District Corps of Engineers Regulatory Branch project manager for this project at least 7 days prior to the pre - dredge meeting. A DNR site -use authorization must also be acquired. 6. Reference: DMMP, 2007.

Introduction. This memorandum reflects the consensus determination of the Dredged Material Management Program (DMMP) agencies (U.S. Army Corps of Engineers, Washington - Departments of Ecology and Natural Resources, and the Environmental Protection Agency) regarding the suitability of up to 16,000 cubic yards (cy) of dredged material from the City of Renton Municipal Airport Seaplane Base for beneficial use or for disposal at the Elliott Bay non - dispersive open -water site. 2. Background. The Renton Seaplane Base serves numerous commercial and recreational seaplanes. The in -water seaplane facilities include a floating dock for passenger boarding and offloading and an aircraft access ramp. The seaplane base is located in close proximity to the mouth of the Cedar River and is subject to sediment deposition, especially during winter storm events. Dredging is required to maintain safe operational depth for seaplane operations (Parametrix, 2006). 3. Proiect Summary. Table 1 includes project summary and tracking information. Table 1.

Proiect Ranking and Sampling Requirements. This project was ranked "moderate" by the ' DMMP program based on its location in Lake Washington (PSDDA, 1988). The sampling and analysis plan (Parametrix, 2006) originally called for dredging of no more than 12,000 cubic yards of City of Renton Municipal Airport Seaplane Base DMMP Suitability Determination —April 10, 2007 sediment. In a moderate - ranked area the number of samples and analyses are calculated using the following guidelines (PSDDA, 1988); • Maximum volume of sediment represented by each field sample = 4,000 cubic yards • Maximum volume of sediment represented by each analysis in the upper 4 -feet of the dredging prism (surface sediment) = 16,000 cubic yards • Maximum volume of sediment represented by each analysis in the subsurface portion of the dredging prism = 24,000 cubic yards Since the total volume was less than the maximum volume that could be represented by one surface analysis, the entire dredging volume was treated as a single dredged material management unit (DMMU). Three field samples (two surface and one subsurface) were to be composited to represent this DMMU. 5. Sampling. Initial sampling for this project took place on November 14, 2006. Difficulties were encountered on several fronts. First, a major storm during the first week of November resulted in significant new shoaling at the seaplane base. Newly deposited sediment ranged from 4 to 6 feet deep. The sampling crew had 10 -foot tubes available but shallower water depths prevented their use at some sampling locations (Currie, 2007). There was not enough clearance to stand the vibracorer upright when using the longer tubes. Therefore, 8 -foot tubes were used, but these could not penetrate deep enough to collect Z- samples. A second problem was the nature of the sediment deposits, which appeared to be unconsolidated with high water content. While penetration to the full length of the core tubes was achieved in most cases, the recovery was poor. Finally, the contractor experienced problems penetrating organic debris in the east half of the project. As a result, sediment cores were only obtained in the west half of the project. Parametrix consulted with the Dredged Material Management Office after the first day of sampling. Because of the significant accretion of sediment from the flood, it was decided that the dredging area should be split into two DMMUs - west and east - to accommodate what was anticipated to be an exceedance of the maximum allowable material for a single DMMU (a subsequent bathymetric survey indicated that this was not the case — the total volume is anticipated to be 16,000 cubic yards or less). See Attachment 1. Also, discussions ensued about getting heavier -duty sampling equipment out in the field for a second round of sampling to ensure penetration to the full depth required. However, the shallow water made access by a large rig impossible. A medium -duty vibracorer was therefore acquired and the second round of sampling took place on November 27. Tube lengths were restricted to 8 feet because of the shallow water. Problems with recovery and organic debris were again I encountered. A more complete account of the two sampling rounds can be found in Attachment 2. Table 2 includes sampling summary information. Table 2.

Further, the DMMP agencies believe the samples adequately represent the material in the dredging prism. Therefore, the sediment ' samples were deemed adequate to fully characterize the proposed dredged material. 6. Chemical Analysis. The approved sampling and analysis plan was followed and quality control guidelines specified by the PSEP and DMMP programs were met, with a few minor exceptions. The data were considered sufficient and acceptable for regulatory decision - making under the DMMP program. ' Sediment conventional results (Table 3) show that the proposed dredged material is predominantly sand. The area to the west of the floating dock is partially protected from currents from the Cedar ' River. The fines content is higher here than in the east half of the project, which is in closer proximity to the mouth of the Cedar River and largely unprotected from its outflow and suspended sediment load. 1 Table 3.

Consequently, bioassay testing was not required of this material. Both DMMUs met suitability guidelines, based on chemistry alone, for open -water disposal at either a dispersive or nondispersive site. 7. Sediment Exposed by Dredging. Sediment exposed by dredging must either meet the State of Washington Sediment Quality Standards (SQS) (Ecology, 1995) or the State's antidegradation standard (DMMP, 2001). Comparison of the proposed dredged material to SQS serves as a first - tier indicator for this purpose. Table 5 (Attachment 4) shows that there were no detected exceedances of SQS. However - while undetected - the reporting limits for 1,2,4 - trichlorobenzene and hexachlorobenzene exceeded SQS. The DMMP agencies believe the probability that these reporting limit exceedances could be masking actual exceedances of SQS is low. Therefore, the exceedances were deemed insignificant. Because the source of the majority of sediment in the project area is the Cedar River, there is no reason to believe that the chemical quality of the sediment to be exposed by dredging differs in any way from the proposed dredged material. Therefore, the agencies agreed that there was no need for the collection or analysis of Z- samples for this project. The sediment that will be exposed by dredging is not anticipated to have any exceedances of SQS. 8. Beneficial -Use Analysis. As indicated in the previous section, the proposed dredged material had no detected exceedances of SQS (and only two undetected exceedances, which were deemed insignificant). The Sediment Quality Standards pertain to marine sediment; therefore the dredged material is suitable for beneficial use in a marine environment. To assess the suitability of the dredged material for beneficial use in a freshwater environment, the freshwater guidelines found in the Sediment Evaluation Framework (RSET, 2006) were used. Table 6 (Attachment 5) shows that there were no exceedances of these guidelines. Therefore, the material is suitable for freshwater use. Finally, to assess the suitability for upland beneficial use, the chemical results were compared to the Model Toxics Control Act (MTCA) guidelines (Ecology, 2005). Table 7 (Attachment 6) indicates that the reporting limits for arsenic exceed the Method B guideline for carcinogens. Naturally occurring elevated concentrations of arsenic are found in some sediments in the Puget Sound region. Therefore, while undetected at the reporting limit, Ecology, DNR and the local health district should be consulted if upland beneficial use is contemplated. Lower -level quantification of arsenic may be required. Also, while there is no MTCA Method A guideline for total chromium, the total chromium value does exceed the guideline for chromium VI. Additional analysis may be required for upland beneficial use in order to determine the chromium VI content of the sediment. 9. Suitability Determination. This memorandum documents the evaluation of the suitability of sediment proposed for dredging from the City of Renton Municipal Airport Seaplane Base for beneficial use or open -water disposal. The approved sampling and analysis plan was followed with the exceptions noted above. The data gathered were deemed sufficient and acceptable for regulatory decision - making under the DMMP program.

Page 5 of 6 City of Renton Municipal Airport Seaplane Base DMMP Suitability Determination - April 10, 2007 Based on the results of the previously described testing, the DMMP agencies conclude that all 16,000 cubic yards are suitable for open -water disposal at the Elliott Bay non - dispersive site. The dredged material is also suitable, from a chemical and toxicity standpoint, for beneficial use in a marine or freshwater environment. Upland beneficial use would require additional consultation with Ecology, DNR and the local health district. This suitability determination does not constitute final agency approval of the project. During the public comment period that follows a public notice, the resource agencies will provide input on the overall project. A final decision will be made after full consideration of agency input, and after an alternatives analysis is done under section 404(b)(1) of the Clean Water Act. ' If a Section 404 permit is issued for this project, a pre- dredge meeting with DNR and the Corps of Engineers will be required. A dredging quality control plan must be developed and submitted to the ' Enforcement Section of the Regulatory Branch of the Seattle District Corps of Engineers at least 7 days prior to the pre- dredge meeting. A DNR site use authorization must also be acquired. ' 10. References. Currie, 2007. Personal communication with Stuart Currie, Parametrix, April 2007. DMMP, 2001.

Field summary: PSDDA Sampling Event, November 27, 2006 Background: During the initial sampling event at the Renton Airport Seaplane Base (11/14/06), recent high flow events within the Cedar River resulted in significantly changed field conditions than were expected based upon pre -flood surveys. A large volume of recently deposited material from the Cedar River was encountered on site, and the resulting shallow water depths combined with fast flowing currents throughout the project area to create challenging field sampling conditions and limited opportunities to obtain acceptable sediment cores. Several attempts were made to collect sediment cores throughout the proposed dredging area. Although site conditions allowed successful collection of sediment cores on the western half of the dredging project, shallow water depths and obstructions beneath the sediment surface led to difficulties collecting satisfactory samples from the eastern half of the dredging project. Specifically, two 10' cores were attempted at Station RS -01 in the east dredge area (i.e., east of the north /south floating dock). Due to the presence of a layer or mat of organic debris (leaves, twigs, etc.) in the deposited material both attempts resulted in refusals at approximately 3' penetration, with less than 2' of material recovered from each attempt. The mat of organic material most probably spread the vibratory action of the vibracorer over a larger surface area than normal, effectively stopping penetration. The relatively light weight of the vibracorer used could not overcome the effects of the organic layer to punch through to a greater depth. Penetration may also have been somewhat affected by the strong current from the diverted flow from the ' mouth of the Cedar River. Upon consultation with the DMMP agencies, Parametrix was directed to mobilize for a second field sampling event. Summary from November 27, 2006 Sampling Event: The second sampling event was conducted on ' 11/27/06 with plans to collect two core samples from the east dredge area (Stations RS -04 and RS -05) in order to account for the increased dredge volume. Based on the anticipated water depths and the debris issues at these stations, a boat and sampling equipment from Marine Sampling Systems were selected for this work. The system selected had the capability to use 8' core tubes, with a maximum possible ' penetration depth of 7'. An additional weight of 120 pounds was added to the vibracorer head to facilitate penetration through organic matter mats or layers. It was anticipated that the maximum core lengths possible, assuming good retention, would be in the range of 5 -7'. (Rev. 01103) November 30, 2006 Page 2 of 2 Station RS -05 was attempted first. The boat approached the Station from the north and was able to sample within approximately 10' of the specified location (lat /long position recorded). The water depth at this station was —4 -5'. Full core penetration (7') was achieved, with approximately 70% recovery (recovered core length slightly less than 6). Sediment appeared to be fine gray sand /silt, with some organic material. The core nose did not contain a "plug" of compressed sediment, indicating that some loss may have occurred during retrieval of the core. The recovered core was judged to be acceptable. Station RS -04 was attempted next. Again the boat approached the Station from the north, but was not able to get within 10' of the specified location due to the shallow water depth. The field crew selected an alternative station (lat/long position recorded), situated as close as possible to the specified location and within the North Boundary line indicated on the sample location figure (attached). Water depth at this location was —1 -2'. Full core penetration (7') was achieved, though several short periods of "hesitation" were noted. These hesitations most probably indicated the presence of debris in the core path. The core retrieved had approximately 50% recovery (recovered core length slightly less than 4'). Sediment appeared to be fine gray sand /silt, with some organic material. The appearance of the core nose indicated that debris was encountered (possibly gravel) and it did not contain a "plug" of compressed sediment, indicating some loss may have occurred during retrieval of the core. The recovered core was judged to be acceptable; however, it was decided to attempt a second core at this location for potentially better recovery. The second attempt at this station was similar to the first. The boat maneuvered back to the previous location, within 6 -8' (lat/long position recorded). Water depth at this location was —1 -2'. Full core penetration (7') was achieved, though several "hesitations ", probably due to debris, were again noted. The core retrieved had approximately 50% recovery, though slightly shorter sediment core length (approximately 35) than the first attempt. Sediment appeared to be fine gray sand /silt, with some organic material. The appearance of the core nose indicated that debris was encountered (possibly gravel) and it did not contain a "plug" of compressed sediment, indicating that some loss may have occurred during retrieval of the core. The recovered core was judged to be acceptable. Based on discussions among Bill Jaworski (Marine Sampling Systems), the Parametrix field crew leader on the boat and the senior Parametrix field crew leader, it was decided that recoveries better than achieved were not likely under the existing conditions. Conclusions: All sediment cores collected during the November 27 field event recovered roughly 3.5 -5 ft of material. Given that full core penetration was achieved (7'), we believe based upon best professional judgment that the sediment cores retained materials collected from sediment depths greater than 5'. While some loss of material from the core nose may have occurred, the differences between penetration and recovery are felt to be primarily the result of compression and /or compaction of the loose depositional materials during the coring process. Given that the Cedar River sediment bedload is the primary source of material deposition within the project area, and that site use has not changed significantly in recent history, it is our belief that the samples collected adequately represents the full dredge prism. i t 1 City of Renton-Municipal Airport Seaplane Base DMMP Suitability Determination - DY 2007 Table 4.

The NMFS prepared this response to your request pursuant to section 7(a)(2) of the ESA, implementing regulations at 50 CFR 402, and agency guidance for preparation of concurrence letters.' The NMFS also reviewed the proposed action for potential effects on Essential Fish Habitat (EFH) designated under the Magnuson- Stevens Fishery Conservation and Management Act (MSA), including conservation measures and any determination you made regarding the potential effects of the action. This review was pursuant to section 305(b) of the MSA, implementing regulations at 50 CFR 600.920, and agency guidance for use of the ESA consultation process to complete EFH consultation.2 Because FEMA determined that the action will not adversely affect EFH, consultation under the MSA is not required for this action. ' Memorandum from D. Robert Lohn, Regional Administrator, to ESA consultation biologists (guidance on informal consultation and preparation of letters of concurrence) (January 30, 2006). 2 Memorandum from William T. Hogarth, Acting Administrator for Fisheries, to Regional Administrators (national finding for use of Endangered Species Act section 7 consultation process to complete essential fish habitat consultations) (February 28, 2001). project, the normal level of activity around the area, and ambient noise levels (including jet aircraft landings and take- offs), effects to listed fish are expected to be insignificant. Similarly, disturbance of listed fish via activities (motion, vibration, in -water activity, etc.) is not expected to greatly exceed existing conditions or be at a level affecting fish. Therefore, effects from these sources are expected to be insignificant. Water quality on this project is a concern since it can be degraded by turbidity and pollutants. Dredging will occur for a period of up to 160 hours on no more than 20 days during the in -water work window (July 16 -31 and November 16- December 31). Chemicals leaking from equipment operating over and near the water can be sources of petroleum -based and other chemicals getting into fish - bearing waters. The project will have a spill prevention and control plan and related spill materials. Turbidity associated with the piling replacement is expected to be minimal. Turbidity from dredging will be minimized by using protective techniques during the operation — like sideboards on the transport barges and `slow' dredging to reduce spillage. The project has been designed to minimize negative water quality effects so turbidity limited to within state water quality standards. Qualified staff will conduct on -site turbidity monitoring during all in -water work. If water quality limits are exceeded, project actions will cease and management practices altered to reduce turbidity to within standards, including installation of a turbidity curtain restricting dispersal of turbid water. Because of the effects minimization measures, timing, localized nature of the project, and limited duration of the in -water work, NMFS anticipates impacts to water quality will be insignificant. The NMFS analyzed the potential impacts of the project on PS Chinook salmon and PS steelhead and determined that the impacts will be discountable and insignificant. The effects will be discountable because PS Chinook salmon and PS steelhead are unlikely to be in the area and thus will not be exposed to the project. Work will be conducted July 16 to 31 and November 16 to. December 31, when rearing juveniles are gone from the area. The work will be conducted in an continuously active area with planes landing and taking off, away from the main migration corridor, near heavily modified shoreline, lacking natural cover - making the area not particularly suitable for rearing juveniles. If a few salmon or steelhead occur in the action area during the project, effects, if any, are expected to be insignificant. Conclusion Because all potential adverse effects are discountable or insignificant, NMFS concurs with the FEMA determination of "may affect, not likely to adversely affect" for PS Chinook salmon and PS steelhead and critical habitat of PS Chinook salmon. Reinitiation of Consultation Reinitiation of consultation is required and shall be requested by the Federal agency, or by NMFS, where discretionary Federal. involvement or control over the action has been 4 A 0 0 retained or is authorized by law and (1) new information reveals effects of the action that may affect listed species or critical habitat in a manner or to an extent not previously considered; (2) the identified action is subsequently modified in a manner that causes an effect to the listed species or critical habitat that was not considered in this concurrence letter; or if (3) a new species is listed or critical habitat designated that may be affected by the identified action (50 CFR 402.16).
