These practices include: Safety/ Environmental Pre-construction meeting The project will start with Boeing Environmental and Safety preconstruction to mitigate any risk associated with project Proposed Hauling/ Transportation routes Contractors will apply for their own hauling traffic control plans permits related to this project. And will follow a city approved route. Construction. The actual Construction will be accomplished by a Construction contractor. The contractor will call for all required inspections, as well as site pre-construction meeting. The contractor will keep records of any special inspections at the construction site  Flaggers will be used to reduce impacts  Activities will be scheduled during the City of Renton approved hours.  Dump trucks will have a cushion of sand to dampen loading noise.  Trucks will use trailers to reduce the number of trips.  Equipment will be shut off during standby activities to limit noise and exhaust.  Materials will be recycled to the extent possible minimizing debris, hauling and preservation of resources.  Activities will be overlapped as much as possible to shorted duration of overall construction duration. BOEING COMMERCIAL AIRPLANE GROUP RENTON WASHINGTON Storm Water - TECS Construction will start with the implementation and installation of Best Management Practices (BMP) for Temporary Erosion and Sedimentation Control (TESC) under supervision of Boeing Environmental personnel. All storm water drain inlets in and around the proposed construction operations and staging areas will be surrounded by oil absorbent padding to mitigate the potential of any hydraulic/fuel leakages emanating from construction machinery entering the watershed As a best management practice, any soil piles resulting from excavation activities will be covered with an impervious material, such as Vis -queen, to minimize and avoid erosion and to prevent silt from entering into the Cedar River Snow, Ice, dirt and mud removal Contractor shall remove snow and ice to the extent necessary to perform the work. The use of calcium chloride or other chemicals will not be permitted to remove snow or ice. Contractor shall assure that vehicles are constructed, loaded, maintained and covered as necessary to prevent the deposition of dirt, mud or other debris on public roadways. Dirt mud or debris shall be removed on continual basis. Any dirt, mud or debris dropped by vehicles shall be removed immediately. Dust Control Through the entire construction period the Contractor shall take all necessary steps to dust control all working area and unpaved roads. The use of calcium chloride or other chemicals will not be permitted for dust control. The Contractor will accomplish dust control by watering and sprinkling to satisfactorily settle the dust. Contractor shall comply with any requirements imposed by law to prevent fugitive dust emissions. All demolished materials and debris will be stockpiled on site to prevent dust and sedimentation from migrating onto roadways. Contractor vehicles that are transporting materials to and from the site will be required to have tires washed prior to leaving the site. This will prevent dust and sedimentation from entering nearby roadways. Airport Mitigation  A pre-construction meeting will set up with the Airport personnel.  The contractor will set up visual controls, and FOD controls including FOD fence.  Contractor will be in communication with airport tower during construction hours.  Contractor personnel will wear reflective vests on Airport apron at all times.

(S&EE) has been retained by you to perform a geotechnical evaluation for the above-referenced project. The project will involve re-configuration of the traffic flow through the existing D-50 gate. I understand that new underground electrical lines will be constructed, some minor re- grading will be performed, and new asphalt pavement will be installed. SURFACE AND SUBSURFACE CONDITIONS The project site is located in the southeastern portion of Renton Municipal Airport. Figure 1, which is included at the end of this report, shows the site location. The existing gate is surrounded by buildings, and the site surface is covered with asphalt pavement. The gate is accessed by East Perimeter Road which borders the west side of Cedar river and its levee. The site surface is relatively flat. S&EE performed a previous soil test boring, B-2, at the location shown in Figure 1. Based on our knowledge of soil conditions in the area, it is our opinion that the boring data are representative of the subsurface conditions at D-50 gate. The boring shows that the subsurface conditions at the site include fill over alluvial soils. The former is about 10 to 11 feet thick and consists of loose to medium dense silty sand, gravel and sand. The alluvial soils include a soft to medium dense silt and sand layer to a depth of about 30 feet, then dense to very dense sand and gravel below. This sand and gravel layer turns into a dense silty sand at a depth of 97.5 feet. Boring B-2 was terminated in this soil. Ms. Cynthia Johnson March 18, 2017 Page 2 Rpt1707 S&EE Groundwater was encountered at a depth of 7 feet during the drilling of Boring B-2. Based on our experience in the project area, the groundwater depth will vary with season and precipitation, and will fluctuate between depths of 5 to 10 feet. CONCLUSION AND RECOMENDATION General It is our opinion that the proposed project is feasible from a geotechnical standpoint. The areas disturbed by construction will be stabilized and should remain stable. It is our further opinion that the project will not incur any soil instability. Underground Utility Construction Subgrade preparation and trench backfill should be monitored by a site inspector from our office. All loose soil cuttings should be removed from the excavation subgrade prior to the placement of bedding materials. In the event that soft or loose soil is encountered at subgrade, the subgrade should be over-excavated for a minimum of 6 inches. A non-woven geotextile having a minimum grab tensile strength of 200 pounds should be installed at the bottom of the over-excavation and the over-excavation be backfilled with 1-1/4” minus crushed rock. The geotextile should be installed flat with all wrinkles removed and have 12 inches overlap. The rock should be compacted to a firm a non-yielding condition using a mechanical compactor approved by our site inspector. The onsite soils are suitable for use as backfill. The soils are slightly moisture sensitive. As such, the contractor should protect the excavated soils from rain. Pavement We recommend that all pavement subgrades be proof-rolled to identify areas of soft, wet, organic, or unstable soils. Proof-rolling should be accomplished with a heavy (12-ton) vibratory roller, front-end- loader, or loaded dump truck (or equivalent) making systematic passes over the subgrade while being observed by a site inspector from our office. In areas where unstable and/or unsuitable subgrade soils are observed, the subgrade should be over-excavated a minimum 6 inches. Woven geotextile having a minimum 200 pounds grab tensile strength may be necessary for additional subgrade stabilization. The geotextile, if used, should be placed with 12-inch overlaps with all wrinkles removed.

ENVIRONMENTAL CHECKLIST 4 4/25/20173/29/201712/18/2012 Task Two Fuel spill containment Apron D Scope of Work The project will add a new fuel containment to the Boeing Apron D which is used for 737 Aircraft stalls. The system is designed to capture any fuel that may be spilled on the apron in an underground holding area. To allow for control and isolation of the storm water flow paths in the event of a spill, the existing 72” storm drainage a manhole will be replaced with an 84” storm drainage manhole. The replacement will allow for the installation of valves to direct the storm drainage flow. To contain any potential fuel the project will install 2 each new 5000 gallon fuel spill containment tanks The project will replace several short (approx. 7LF each) sections of existing 24 & 12 diameter pipes. The system is being designed to maintain the current operating conditions of the existing system only making modifications to allow for containment and isolation of potentially fuel laden storm flows. The hydrology of the normally operating system will not be impacted by this project.
