This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. INSTRUCTIONS FOR APPLICANTS: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision-making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. INSTRUCTIONS FOR LEAD AGENCIES: Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. USE OF CHECKLIST FOR NONPROJECT PROPOSALS: [help] For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not contribute meaningfully to the analysis of the proposal.

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.) Project Narrative The Boeing Apron E project consists of 2 major components: The new Paint hangar facility building and three new production aircraft stalls. The Boeing Company is planning to convert the existing S1 parking lot into three production stalls for aircrafts, a two-bay paint hangar, and a new utility building. This will require demolition of the existing fire station, which will be relocated north to Boeing’s existing S2 parking lot. The relocated fire station will be under separate permits and review . Utilities from the main Boeing plant north - via N. 6th street will be used to feed part of the utility needs of the project Landscaping, a 25 foot high sound wall and blast fences are incorporated in the design. Approximately 1,000 parking stalls will be displaced by this project. Boeing currently has approximately 1,500 available stalls located in Lot E7, 10-20 Garage, Lot E1 and 10-18 Garage. A new stormwater treatment system will be installed including an oil/ water separator vault system. Paint hangar facility building The construction of a new paint facility building approximately 235’ x 307’ will include: two aircraft bays to accommodate 737 aircraft up to a MAX 10 model, but no larger models; three mechanical chase blocks located at the center and both ends of the building (running north-south direction); and a two-story facility support function area to the south of the hangar spaces, and to include various storage and process support areas as well as office and conference room spaces. 5 D:\ECF_SEPA_Checklist_Renton_Apron E_190701_v1.pdf.docRev: 08/2016 The proposed paint hangar is an unfueled Group I aircraft paint hangar with associated functions that are designed per the International Building Code 2015 as adopted by State Building Code Council WAC 51-50 and amended by Renton Municipal Code 4-5- 060. The proposed function and the required specialized equipment for this function drives us to the Special Industrial Occupancy classification for this building, with a mixed occupancy of S-1 for the high-bay areas and accessory H occupancies for paint mixing/storage, with associated B (office), A (locker rooms/conference rooms) occupancies. Boeing requires the use of stacker cranes in the current painting process. These stacker cranes are a specialized piece of equipment hung from the overhead structure, running on rails attached to the bottom chord of trusses, and telescoping down to the painting envelope around the aircraft. The use and construction of the proposed paint hangar will require the building height to be a minimum of high, as shown on the preceding cross-section. The tail height of the 737 MAX is 40’-8”. The estimated truss depth for this span is 15’-0”. The depth of the parapet (min. 42” high at the roof ridge) plus structural decking, insulation and roofing is 5’-0”, and finally, the retracted depth of the stacker crane is 23’-0”. The proposed height of 80' gives us a minimal clearance at the vertical tailfin of 1’-4” to bottom of stacker crane platform. This ’ height is estimated as a minimum height for the building. Production aircraft stalls The proposed new stalls project will consist removal of existing asphalt, New utilities, electrical, lighting, mechanical, sewer, storm and fire. The apron will be re- graded and new concrete and asphalt will be laid. The three stalls will be at the north boundary of lot S1. Each stall shall include blast fence and sound wall directly behind each aircraft. Location of each blast fence shall be coordinated with utilities and its routings. Design of trenches for utilities including shoring, dewatering, bedding/fill materials, compaction and pavement restoration. Trenching of utilities from the main Boeing plant under north 6th street to lot S1. New spill containment systems and of de-icing systems will be installed. Located between the west and middle aircraft stalls are a double bay super crew shelter (24’ x 50’) and a double bay super tool cabana structure (24’ x 65’) that holds men and 6 D:\ECF_SEPA_Checklist_Renton_Apron E_190701_v1.pdf.docRev: 08/2016 women restrooms. A standard single-bay crew shelter (12’ x 30’) and a single bay tool cabana (12’ x 30’) would be positioned east of the easternmost aircraft stall. See the appended Vicinity Map and Site Map for location information . 12. Location of the proposal.
