(Lead agencies may modify this form to include additional specific information on project description Project Description The project consists of three separate tasks at the Boeing main Renton plant and at the Renton Municipal airport. Replace sewer lift station near 4-42 Fuel spill containment at Apron D, Modify D-50 gate entrance Task one Replace sewer lift station near 4-42, Replace sewer lift station is just west of the 4-42 bldg underneath the Boeing internal roadway on the east side of the Cedar River Task two Fuel spill containment at Apron D, Fuel spill containment at Apron D is near the Boeing south bridge adjacent to the Boeing access road east of the river ENVIRONMENTAL CHECKLIST 3 6/30/2017 Task three Modify D-50 gate entrance Modify D-50 gate entrance is adjacent to East. Perimeter road and west of the Cedar River on Boeing leased airport property. Task one Replace sewer lift station near 4-42 Scope of Work The scope of work for this task involves replacement of Building 4 -42 sewage lift station. This lift station serves Building 4 -42, 4-41 and west side of Building 4-20. The new lift station shall be constructed and readied to place on line. During an outage, the sewer pipes shall be switched from the old lift station to the new lift station without impacting the building operations. Design of the new lift station shall take into effect the need to keep the buildings operational except for the switchover. Reroute existing fire line for new lift station The scope of work includes installation of a new vault for collection of sewage, two new submersible sewage pumps, controls and piping. A new 8” sewer line from sewage collected from Building 4-42 and 4-41 will be rerouted to the new 8 ft. sewage lift station vault. A 48” diameter manhole will be installed to collect the sewage upstream of the new vault The 4” discharge line from the new sewage pumps will be connected to the existing 4” sewage discharge line just south of the new lift station. The old sewage lift station will be demolished and filled in after the new lift station is put into service. Impervious surface disturbance is approx. 1900 sq. ft. ENVIRONMENTAL CHECKLIST 4 6/30/2017 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. The project will then replace 840 sq. ft. of existing Asphalt pavement, and 750 sq. ft. of concrete pavement for a total of 1,590 total replaced pavement Task 3 Modify existing Boeing Gate D-50 entrance to add a pedestrian walkway path Scope of Work ENVIRONMENTAL CHECKLIST 5 6/30/2017 This scope of work for this task involves of removal of a 24ft automatic gate and 60 ft. of existing fencing to create new opening, Remove asphalt and curbing. The Installation of 136 LF of new 7 ft. high fencing, and new 36 ft. wide double swing gate. Add 1each traffic control swing arm Replace Approx. 3280 sq. ft. of existing Asphalt Add 2 new concrete filled steel bollards Add new 3 x 7 exterior door, 4x 4 metal landing, metal stairs and 3x5 awning at existing guard house Relocate 2 each light fixtures 7’ high on existing guard shack.
