The symposium papers.presented . average figures for standing-storage loss from floating-roof tanks expressed as barrels per foot of diameter per year per.pound of true vapor pressure. Wide variation in the data was noted and further effort on correlating test results was • recommended. Losses from butt-welded tanks with close-fitting seals also required.. additional consideration. The API Evaporation Loss Committee, in 1957, collected from the petroleum . . industry both new and previously obtained data on evaporation loss from floating- roof tanks. An intensive study was made of these data. As a result of this study, the effect of an additional variable, wind velocity, was determined and the earlier variables were defined more precisely resulting in a significant reduction in the spread of data for the various types of floating-roof tanks. This bulletin presents the resultant correlations for use in estimating evaporation loss. *To supplement the general description of equipment covered in API Bulletin 2513: Evaporation.Loss in the Petroleum Industry—Causes and Control, informa- lion is presented herein which deals with the vital seal portion of the floating roof. In addition to the metallic-shoe type of seal, the nonmetallic seal is discussed and a comparison is made of the features of each. A guide to the selection, maintenance, and replacement of the floating-roof seal—based on manufacturers' publications, users' experience, and tests—is in- eluded in this bulletin. . • • • ."Symposium on Evaporation Loss,"Proc.

SP-066-77 LOCATION: Approximately 1,000 feet south of intersection of future S.W. 23rd Street and Lind Avenue S.W. SUMMARY OF REQUEST: Applicant requests the approval of the addition of a 50,000 barrel gasoline storage tank with an internal covered floating roof and a vapor recovery system as per Renton Bulk Storage regulations. Storage tank will be within existing filled and developed area. SUMMARY OF ACTION: Planning Department Recommendation: Approval with conditions. Hearing Examiner Decision: Approval with conditions. PLANNING DEPARTMENT The Planning Department staff report was received by the REPORT: Examiner on January 31, 1978. PUBIC HEARING: After reviewing the Planning Department report, examining available information on file with the application, and field checking the property and surrounding area, the Examiner conducted a public hearing on the subject as follows: The hearing was opened on February 7, 1978 at 10:50 a.m. in the Council Chambers of the Renton Municipal Building. Parties wishing to testify were sworn. It was reported that the Hearing Examiner and the applicant had received and reviewed the !Planning Department report, and the report was entered into the record as Exhibit #1. Michael Smith, Planning Department, reviewed Exhibit #1, and entered the following additional exhibits into the record: Exhibit #2: King County Assessor's Map Exhibit #3: Plan of the Proposed Tank Exhibit #4: Elevation Drawings Exhibit #5: Construction Details (4 pages) Exhibit #6: Site Map Exhibit #7: Landscape Plan with staff comments Exhibit #8: Landscape Plan as submitted Exhibit #9: Letter to Department of Ecology from King County Division of Hydraulics, dated January 3, 1978, regarding flood control zone application. The Examiner asked a representative from the Renton Fire Department to testify. Responding was: SP-066-77 Page Two Pamphlet 30, and the Uniform Fire Code. He also indicated that representatives of the corporation had agreed to installation of an alarm system as requested. The Examiner asked the applicant if he concurred in Exhibit #1. Responding was: Steven Kelly, Attorney 1103 IBM Building Seattle, WA 98101 Mr. Kelly indicated that certain provisions of the report were objectionable which he would address in his testimony. He referenced Section 0.5 relating to landscaping provisions and indicated that although he objected to provision of landscaping to the extent recommended in the report, landscaping would be provided along Lind Avenue upon completion of the roadway project and suggested a conformance deadline of 180 days following completion of construction as acceptable to the corporation. Regarding Section 0.6, Mr. Kelly emphasized that because of the nature of the fence for security purposes, the 80% opaque requirement would prevent personnel from visually monitoring the site. He noted that in Section 0.8, the date of issuance of the Department of Ecology permit for waste discharge should be revised to January, 1978. Referencing Section 0.12 relating to an on-site fire suppression system, Mr. Kelly expressed strong objection to the requirement for an automatic foam system, emphasized the adequacy of the current manual foam system, the expense of converting the system, and stated that such systems currently are not in operation on the west coast. Regarding requirements of the Bulk Storage Ordinance, he felt that the intent of the requirements contained in the ordinance were designed to apply to new facilities and not to additions to existing facilities. The Examiner asked for further comments. Responding was: A. E. McCluskey Environmental Conservation Manager Mobil Oil Western Region 612 S. Flower Street Los Angeles, CA 90017 Mr. McCluskey reported that the Mobil Oil facility meets all requirements of NFPA Pamphlet 30 and the Uniform Fire Code. He indicated that if such automatic foam systems were available and approved by Underwriters Laboratory they would be included in the requirements of the referenced documents, and would be installed and utilized for petroleum storage by all companies. He emphasized that such automatic systems were not currently in use either by Mobil or other corporations. He explained the physical nature of the storage facilities located in the City of Renton and indicated that advantages to the closed tank because of the space between the top of the tank and the floating roof included effective control of fires with foam injection systems either above the roof or through submersible injection. He reviewed disadvantages to an automatic system which included inadvertent reaction to stimulation other than fire by the system; utilization of all available foam creating an emergency situation in the event of a subsequent fire; contamination of unleaded petroleum products resulting in noncompliance with federal regulations for maintenance of leaded and unleaded products on site and subsequent $10,000 per day fines; safety hazards for on-site personnel; and requirements for additional provision of storage for foam system. Advantages to the existing manual system included ability to direct foam to specific areas; personnel previously trained to effective utilize system; and capability to connect to existing fire department alarm system. He noted that the corporation had contributed $300,000 for construction of a water main along Lind Avenue in the event of future expansion and stressed that the corporation maintains a 10-year safety record utilizing the current manual ADT system. In response to the Examiner's inquiry regarding expense of conversion to an automatic system, Mr. McCluskey deferred his response to a representative of National Foam Systems, Inc. Responding was: Martin Boyd Sales Engineer, National Foam Systems, Inc. 2054 S_ 308th Street SP-066-77 Page Four 2. The Planning Department report accurately sets forth the issues, applicable policies and provisions, findings of fact, and departmental recommendations in this matter, and is hereby attached as Exhibit #1 and incorporated in this report by reference as set forth in full therein. 3. Pursuant to the State Environmental Policy Act of 1971, as amended by R.C.W. 43.21.C. , a Declaration of Non-Significance has been issued for the subject proposal by the State Department of Ecology, lead agency. 4. Plans for the proposal have been reviewed by all city departments affected by the impact of this development. 5. There was no opposition to the proposal expressed. 6. ;All existing utilities are available and in close proximity. 7. The proposal is compatible with the requirements of Section 4-713 (H-1) of Title IV, Ordinance No. 1628, Code of General Ordinances. 8. The proposal is compatible with the requirements of Section 4-734 (Bulk Storage Regulations) of Title IV, Ordinance No. 1628, Code of General Ordinances, except for: .a. Section 7-734. (J) : requirement for two access points. lb. Section 4-734. (H) : requirement for approval of the storm drainage plans by the Public Works Department. c. Section 4-734. (N) , (0) , (P) : requirement for certification of meeting all pollution control regulations. d. Section 4-734. (0) .3: requirement for fully automatic fire suppression system. Once the Lind Avenue South local improvement district is completed adjacent to the subject site, the proposal will have two access points from the site onto Lind Avenue South, thereby complying with Section 4-734. (J) . Storm drainage plans have been reviewed by the State Department of Ecology (Exhibit • #1) and the King County Department of Public Works (Exhibit #9) . No testimony was entered into the record as to the decision of the city Department of Public Works relative to the storm drainage plans. The former agencies have approved the proposal. Certification by the applicant of compliance with all of the applicable pollution ' and emission regulations will occur during three months of monitoring the site after construction of the additional oil storage tank. Certification is also to occur regarding Section 4-734. (0) .10, ground surfaces. The fully automatic fire suppression system as specified has not been adequately developed in the industry at this time. The Fire Department, therefore, recommended connection of the existing foam system to the tank, an automatic alarm system for the tank, and connection of the alarm system to the Valley Communications Center. This was acceptable to the applicant. 9. The Mobil Oil storage facility existed prior to enactment of Section 4-734, and therefore, was not evaluated per the location requirements of Section 4-734. (G) . But per Section 4-726. (B) the facility is in any case allowed to continue as a nonconforming use. Although Section 4-726. (B) .3 does not permit extension of nonconforming uses such as is proposed, Section 4-734. (P) .11 allows for expansion 1. of existing facilities that emit hydrocarbons provided the produced emissions do not exceed twice the annual permitted emission levels. The staff report, Exhibit #1, paragraph 0.11 stated that the information supplied by the applicant indicated that the emission levels of Section 4-734. (P) would be met. Conformance with these emission levels must be established during the first three months of operation of the facility (Section 4-734. (P) .7) . The Puget Sound Air. Pollution Agency approved the evaporation recovery system (Notice No. 1789, Exhibit #1) as well as the Public Works Department (Letter dated August 9, 1977, Exhibit #1) . 10. Existing vegetation surrounds the facility on all but the northerly portion. Landscaping per Exhibit #8 was submitted to comply with the screening and landscaping requirements of Section 4-734. (E) . An eight-foot security fence surrounds the site. SP-066-77 Page Three further explained that the industry has not improved the system because of potential problems associated with it, such as false alarms caused by lightning, and danger of contamination by foam to the oil product causing expense and inconvenience to restore the product to its original specifications. He emphasized that the current manual system is in compliance with NFPA standards and that no automatic actuating foam system exists currently on the west coast of the United States. The Examiner asked for testimony in favor of the application. There was no response. The Examiner asked for testimony in opposition to the application. There was no response. Mr. Smith clarified a point raised by Mr. Kelly regarding deferral of landscaping requirements and advised that application for such deferral should be made to the City of Renton Board of Public Works which meets each Wednesday at 9:00 a.m. The Examiner asked,Mr. Smith for clarification of Section 0.1 regarding an interior portion of the dike in relationship to the 80% obscuring oqaque fence. Mr. Smith explained requirements for removal of an interior portion of the dike to provide spill protection. In response to the Examiner's inquiries, Mr. Smith advised that the Public Works Department had reviewed existing storm drainage plans and locations of catch basins on the site and review had occurred by the Department of Ecology for the waste discharge permit, but specific new plans would be reviewed during application for a building permit; odor standards would be required to be certified within a 90-day period; and explosive location requirements of Section 4-734.6 would be reviewed for compliance with the Washington State Explosive Act although Mr. Smith felt that it may not apply to storage of petroleum products. He also reported that certification would be required to assure compliance with requirements of the ordinance by the dike area due to surface water table in the vicinity. Regarding Mr. Kelly's concern regarding the 800 ogaque screen requirement, the Examiner inquired if alternatives to the proposal would be reviewed. Mr. Smith felt that due to the height and location of the existing fence, installation of berms and landscaping could be reviewed by the Planning Department to provide effective visual control and maintain visibility for safety purposes. Reiterating previous discussion regarding the automatic detection system, the Examiner asked Mr. Wooton for final comments from the department. Mr. Wooton reported that connection of the proposed storage tank to the existing manual system and connection of an automatic alarm system to the Valley Communications Center would satisfy departmental requirements in conjunction with NFPA Pamphlet 30 and the Uniform Fire Code. The Examiner asked Mr. Kelly to further explain concerns regarding the 80% opaque requirement of Section 4-734(E) l. Mr. Kelly and Mr. McCluskey reported 24-hour traffic activity on the site, height and type of vehicles utilizing the site, and felt that the proposed fencing would impede safety. Mr. Kelly expressed the opinion that since the dike area would not be revised, changes should not be required to the nature of the dike itself to bring the entire facility up to ordinance requirements. He assured the Examiner that compliance with federal and state guidelines would be met to prevent occurrence of contamination of soil and subsurface water. He reiterated previous objections to the proposed automatic detection system and briefly explained the current manual foam system in operation at the facility. The Examiner asked Mr. Smith for final comments. Mr. Smith explained departmental review and application of the Bulk Storage Ordinance with regard to the non-conforming section of the Zoning Ordinance and indicated that although Mr. Kelly's concerns may apply to existing tanks on the site, review of the proposed tank must be made individually with regard to landscaping and screening. He reported that Exhibit #1 would remain as submitted with the exception of Section P.2 of the Planning Department recommendation relating to fire suppression systems which should be revised per recommendations of the Fire Department representative through his testimony. He noted that deferral of landscaping requirements should be reviewed by the Board of Public Works, and discussion and review of the opaque screening fence be accomplished by the Planning Department to determine necessity of berming. The Examiner asked for further testimony. Since there was none, the hearing on Item #SP-066-77 was closed by the Examiner at 12:10 p.m. FINDINGS, CONCLUSIONS & RECOMMENDATION: Having reviewed the record in this matter, the Examiner now makes and enters the following: FINDINGS: 1. The request is for approval of a special permit to allow construction of a 50,000 barrel gasoline storage tank to the existing Mobil Oil Corporation bulk storage facility. SP-066-77 Page Six 5. Modification of the existing dyke (Exhibit #6) per approval of the Fire Department 'for conformance with applicable standards. 6. Implementation of the landscape plan, Exhibit #8. Upon removal or decrease of the existing vegetation at the perimeter of the site for construction of Lind Avenue South or Strander Boulevard, the need for additional landscaping and/or modification of the security fence should be evaluated by the Planning Department with the 'applicant for a mutually agreed upon solution. If possible, the rights-of-way for both streets should be used per a mutual agreement to assist in meeting these. landscaping requirements. ORDERED THIS 16th day of February, 1978.

Delaurenti I Councilman George J. Perry Councilman Richard M. Stredicke Warren C. Gonnason, Public Works Director Gordon Y. Ericksen, Planning Director (2) Ron Nelson, Building Division Lawrence J. Warren, City Attorney 1 Pursuant to Title IV, Section 3015 of the City's Code, request for reconsideration must be filed in writing on or before March 2, 1978. Any aggrieved person feeling that the decision of the Examiner is based on erroneous procedure, errors of law or fact, error in judgment, or the discovery of new evidence which could not be reasonably available at the prior hearing may make a written request for review by the Examiner within fourteen (14) days from the date of the Examiner's decision. This request shall set forth the specific errors relied upon by such appellant, and the Examiner may, after review of the record, take further action as he deems proper. An appeal to the City Council is governed by Title IV, Section 3016, which requires that such appeal be filed with the City Clerk accompanying a filing fee of $25.00 and meeting other specified requirements. Copies of this ordinance are available for inspection in the City Clerk's office, first floor of City Hall, or same may be purchased at cost in said office. SP-066-77 Page Five 11. Storm drainage plans have been approved by the Department of Ecology (Flood Control Zone Permit No. 1-2772-2, Exhibit #9, and Waste Discharge Permit No. WA-000194-5 (I) , Exhibit #1) . The Public Works Department has yet to decide upon the drainage plans. 12. The proposed tank will be located within an existing dyked containment area shared by existing tanks. CONCLUSIONS: 1. The proposal conforms to the goals and objectives of the Comprehensive Plan for the Green River Valley. Prior to passage of the Comprehensive Plan for this area (Ordinance No. 3037, June 14, 1976) the Mobil Oil storage facility existed on the site. Therefore, the Comprehensive Plan can only be applied to the proposed additional tank. On all but the easterly side of the tank, existing vegetation exists to screen the tank. Existing landfill will be used for the tank. The net impact of the additional tank will be minimal relative to the existing facility. 2. The requirements of Sections 4-734. (H) , (J) , (N) , (0) , and (P) can be met. Construction of Lind Avenue South will provide the required access. All but the Public Works Department have approved the storm drainage plans. Certification regarding conformance with applicable pollution and emission regulations will occur three months after construction as a result of monitoring the site. The recommended fire suppression system will be installed. The normal inspection of the construction and building permit by the appropriate departments will achieve satisfactory compliance with Section 4-734. 3. Due to the existence of the Mobil Oil storage facility prior to enactment of Section 4-734, the proposed storage tank is the only portion of the facility that must technically conform to the requirements of that ordinance. 4. Adequate vegetation and security fencing exists around the proposed tank, except along the easterly side of the tank where the existing tanks are located,provided the existing vegetation remains as is. The proposed landscaping (Exhibit #8) along the northeasterly corner and northerly portion of the site should adequately provide the screening required for the proposal. Upon removal of the existing vegetation along the site perimeters to accommodate Lind Avenue South and/or Strander Boulevard, the need for additional landscaping and/or modifying the security fence should be evaluated by the Planning Department in cooperation with the applicant for a mutually agreed upon solution. It should be noted that it seems unreasonable to require full compliance with Section 4-734. (E) along the perimeter fence since this fence encompasses the total site, of which the proposed tank is a small part. The impact of the existing tanks east of the proposed tank seems to reduce the effectiveness any screening or fence modifications might have at the perimeter of the total site relative to the added tank. Although the facility might be nonconforming with regard to requirements of Section 4-734, it is unreasonable to impose the requirements of the ordinance retroactively upon the total site. 5. Required approvals of other agencies have been secured. Monitoring of the site for three months after construction is, the only requirement remaining to be accomplished. DECISION: Based upon the record, testimony, findings and conclusions, it is the decision of the Examiner to approve the Special Permit as submitted subject to: 1. Compliance with all of the requirements of other agencies relative to storm drainage, pollution and emission standards. Certification is to occur per Section 4-734. (P) .7 and other applicable requirements. 2. Construction of a fire suppression system to consist of connecting the existing foam system to the proposed tank, installation of an automatic alarm system for the proposed tank, and connecting the existing and added fire alarm systems to the Valley Communications Center per approval of the Fire Department. 3. Construction of access to Lind Avenue South when the street is constructed per approval of the Public Works Department. 4. Compliance with the sound, liquid waste, light and glare, odor, emission and pollution standards of Section 4-734. - ` �++ G P '-_�: - .j ,FI „+ : !1 yQV lI �1 a -'III I.) --Iv!! .:24,..-__loc. , 441.-1 , _41: t. .-:.4, z . .44 __ 41 . v _ ... . 4 ) i� f r i I - Ci � l-__�� +-.�.- T , r.�i 1/4_I' —.t—"mil .. >i_— 1 . }— r — 11v 1 W DEQ DO�.J 'net, CLAIM yy�-- \ I - -- ,4 _ _ - f.m i--' IT- --- • < t ' 7._ pi _ 0/ _ . 0 11 ___, Bi l _ -- - J 74 U a -- _ _ ., 61 Qi 6 li • ,.

PLANNING DEPARTMENT ANALYSIS : 1 . The proposed construction will be entirely within the exist- ing filled and diked area . An interior portion of the dike has been removed to provide spill protection meeting National Fire Protection Association Code (minimum holding capacity of 100% of the single largest tank) . The barrier required under Section 4-734. 0. 2 was omitted from the ordinance by the courts . 2. Section 4-734(6) . 3 establishes the responsibility to the applicant of proving compliance with the bulk storage regulations . 3. The proposed 50 ,000 barrel storage tank meets the maximum height of 40 feet established in Section 4-734(C ) . 4. The proposed tank complies with the setback requirements of Section 4-734(D) . 5. The proposal complies with the landscaping requirements of the bulk storage regulations . The existing natural areas . west of the site and at the southeast corner are to be retained in a natural state to provide screening . At such PLANNING DEPARTMENT PRELIMINARY REPORT TO HEARING EXAMINER PUBLIC HEARING OF FEBRUARY 7 , 1978 PAGE FOUR RE: MOBIL OIL CORPORATION , SP-066-77 , SPECIAL PERMIT time as they are filled and/or developed , landscaping shall be installed per ordinance requirements . Additional land- scaping is proposed along the north property line and along the portions of the east property line which do not have existing natural trees and vegetation . The area south of the existing dike (constructed on the property line ) is owned by Glacier Park Company and is proposed as the future location for Strander Boulevard. It is assumed this area will remain in a natural state until the proposed roadway is constructed. At such time , additional landscaping will be installed as part of the street improvements . Any special permit approval should be conditioned upon Plan- ning Department review and approval of landscape plans and preservation areas . 6 . An existing eight (8) foot cyclone fence is located around the entire perimeter of the site . This must comply with the 80% opaque requirement of Section 4-734 ( E ) 1 only along and in conjunction with those areas to be landscaped . At such time as natural vegetation is removed in other areas around the site perimeter, conformance to this requirement will be necessary. 7. Any further signing shall conform to the requirements of Section 4-734( F) . 8. Drainage facilities have been reviewed and approved by the Department of Ecology in conjunction with a National Pol - lutant Discharge Elimination System Waste Discharge Permit. Permit No . WA-000194-5 ( I ) was issued by the Department of Ecology on / ,� subject to conditions . (See copy of at "che p rmit. ) Any special permit approval should also reference the conditions established in the NPDES permit. All storm drainage facilities for any site development shall also be subject to final Public Works Department approval . 9. Permits from Puget Sound Air Pollution Control Agency for construction of the vapor recovery system and the 50 ,000 barrel gasoline storage tank with Ultraflote Corporation floating roof were issued on November 8 , 1977 , and Novem- ber 2 , 1978 , respectively. The proposed facility must meet the ambient air quality standards specified in Regulation 1 of PSAPCA (4-734 ( I ) 1 ) . 10. Section 4-734(P), also relating to control of air contani - nants , requires that the applicant provide an initial report that certifies compliance with the established standards . 11 . Section 4-734( P) 13 requires all existing facilities to comply with the emission standards of the ordinance . The proposed vapor recovery system and floating roofs are intended to meet this requirement. It will be necessary for the applicant to certify this once the facilities are installed and operational . Projected emissions calcula- tions have been provided with the application , which indi- cate hydrocarbon emissions below the 100 tons per year maximum allowed by Schedule 4-134(P) 1 . 12. The existing facility has an on-site fire suppression system. Any new construction must meet the requirements of 4-734 0. 4 . (See Fire Department comments . ) 13. Access to the site is presently via a joint roadway with Olympic Pipe Line Company , which extends from the northeast PLANNING DEPARTMENT PRELIMINARY REPORT TO HEARING EXAMINER PUBLIC HEARING OF FEBRUARY 7 , 1978 PAGE FIVE RE : MOBIL OIL CORPORATION , SP-066-77 , SPECIAL PERMIT corner of the Olympic Pipe Line site to East Valley Road. Although this does not meet the strict application of Section 4-734 (J ) 1 , a new access to be coordinated with the Lind Avenue street construction and indicated on the site plans will provide suitable access to the subject site. Proposed curb cuts and driveway widths shall be designed and approved as part of the Lind Avenue project per Public Works Department approval . 14. S.ound levels appear to be within acceptable levels per State and City of Renton law. Enforcement of the maxi - mum noise level standards is by complaint only. 15. Liquid waste discharge must meet all State standards . See attached National Pollutant Discharge Elimination System Waste Discharge Permit issued by the Department of Ecology with various general and special conditions (Section 4-734(L ) ) . 16 . Although the proposed use would not by itself normally be considered consistent with the proposed land uses established in the Comprehensive Plan for the Valley area (manufacturing park) , it can be considered a reason- able addition to an existing facility in an existing previously established H-1 Heavy Industry District. The fact that the applicant proposes to provide landscape screening around the site perimeter and/or preserve natural screening vegetation lends compatibility to certain elements of the Comprehensive Plan . P. PLANNING DEPARTMENT RECOMMENDATION : Recommend approval of the special permit for the 50,000 barrel petroleum storage tank, together with the installation of the vapor recovery system subject to: 1 . Certification by the applicant that the facility meets all air emission standards established in Section 4-734(P) as part of a report to be filed per 4-734(P) 7. 2. Compliance with the fire protection requirements of the Uniform Fire Code and NFPA 30 and Section 4-734 (0)4. 3. Compliance with the conditions established within the National Pollutant Discharge Elimination System Waste Discharge Permit No . WA-000194-5 ( I ) issued by the Depart- ment of Ecology. 4. Compliance with the requirements of. PSAPCA, Regulation I , air emission standards . 5 . Compliance with any requirements established as part of the State Flood Zone Control Permit issued January 19 , 1978. 6.

COMMENTS : — — ----- - -.. — --- . • Introduction The State Environmental Policy Act of 1971 , Chapter 43.21C, RCW, requires all state and local governmental agencies to consider environmental values both for their own actions and when licensing private proposals . The Act also requires that"an EIS be • prepared for all major.actions significantly affecting the quality of 'the environment. . The purpose of this checklist is to help the agencies involved determine whether or not a proposal is such a major action. Please answer the following questions as completely as you can with the . information . presently available to you. Where explanations of your answers are required, .or where • you believe an explanation would be helpful to government decision makers , include your ' explanation in the space provided , or use additional pages if necessary. You should include references to any reports or studies of which you are aware and which are rele- vant to the answers you provide. Complete answers to these questions now will help all . agencies involved with your proposal to undertake the required environmental review with- out unnecessary delay. . The following questions apply to your total proposal , not just, to the 'license for... which you are currently applying or the proposal for which approval is sought. Your answers should include the impacts which will be caused by your proposal when i,t is' completed, even though completion may not occur until_ sometime in the future. This will allow all . of the agencies which will be involved to complete their environmental review now, with- out duplicating paperwork in the future. • NOTE : This is a standard form being used by all state and local agencies in' the State . ' of Washington for various types of proposals. Many of the questions 'may' not •apply to' your proposal . If a question doer not apply, just answer it no and' continue on to the next question.

Any other cover, whether contact or non-contact, without this required projection RAMP EDGE into the product will suffer reduced efficiency SEE NOTE. 2 and also hazardous operation as a result of ^^ y' / the following conditions: A. Seal friction can raise the rim plate or the entire cover during withdrawal enough to allow vapor to escape and expose liquid surface. Seal friction during fill can depress a shallow rim or thin cover allowing product to flow onto the cover. B. Atmospheric low pressure cells cause any trapped vapor to expand and escape. C. Differential thermal expansion of the cover structure causes out of plane warpage thereby raising or lowering sections of the cover again allowing vapor to escape. D. Diurnal thermal cycles from solar radiation causes expansion and contraction of _ any trapped vapor thus raising and lowering the cover with the same results. (The conditions described in C and D are a primary cause of the reduced efficiency experienced with sandwich type covers and other contact covers.) E. Insufficient vapor capacity under the cover or shallow rim plates or covers with " no projecting rim plates prevents the containment of vapor slugs or entrained vapor in the fill stream which will "burp" past the cover edge. The optimum design of the ULTRAFLOTL' Cover allows the vapor space to contain any vapor volume changes and then return to a state of equilibrium without "burping" and without creating any other hazardous condition. 2. Ramp edges are required on rim plates to preclude the possibility of damage to the cover should the rim plate contact the tank shell. A straight rim plate would hang up on welds, rivets, •plate offsets, burrs, etc. that normally occur on tank shells. 3. The rounded edges of rim plates precludes the possibility of tearing the deck skins from any loading experienced by the cover. *U.S.PATENT NO.' 3861555 OTHER U.S.AND FOREIGN PATENTS PENDING o�,WEq ULTRAFLOTE CORPORATION tO/ (a/`PROFESSIONAL N R I M PLATE AND SEAL DETAILS RI ARDELL H.

NAME OF PROPOSAL, IF APPLICABLE: Install 50, 000 barrel gasoline storage tank and vapor recovery unit on loading rack at Renton Terminal. , 1. 6. NATURE AND BRIEF DESCRIPTION OF PROPOSAL: Tank to be internal covered floating roof type constructed according to American Petroleum Institution specification 650. Tank to be diked and protected according to recommendations • of the National Fire Protection Association No. 30. The tank will receive and store gasoline for distribution to customers. Install gasoline terminal vapor, recovery system consisting of a vapor hose connection, vapor lock and vapor recovery unit. The vapor hose connection consists of four-inch diameter flexible rubber hose with female coupler at one end for connection to the vapor return line of the tank truck. During bottom filling operation, the incoming liquid gasoline , displaces the vapor inside the empty tank truck and pushes it out through the vapor dome and into the vapor hose. From here, gasoline vapor mixture passes through the check valve, flame arrester and into the main vapor line. The vapor line is a pipe to convey the gasoline vapor mixture into the recovery unit. Located at -the lowest portion of the vapor line is a condensate tank to collect any condensation. Any condensation on this tank is pumped out into the regular gasoline tanks. The vapor recovery unit has a vapor condensor With cooling coils that could be maintained at 90°F. The, gasoline vapor mixture passes through these coils where gasoline vapor condenses and collects at the water - gasoline Separator tank. The cooling coils are defrosted periodically to remove water. The collected gasoline in the separator tank is transferred into one of the regular gasoline tanks. I. 8. ESTIMATED DAY FOR COMPLETION OF PROPOSAL: It is estimated that the 50, 000 barrel gasoline storage tank would be completed in 1979. it is proposed that the gasoline terminal vapor recovery system be completed by September, 1978. • - I. 9.

It appears from review 'of the checklist that this is an addition ;aithin the existing diked tank farm area and does hot represent a major expansion either within or beyond the existing diked area . It is our understanding that the applicant will include a vapor recovery system and floating tank roofs , together with all the necessary safety devices to meet City of Renton and other appli - cable standards . This will significantly reduce the environmental impact of the proposed project as well as the existing facility . We also understand the proposed 50 , 000 barrel tank will be con- structed entirely within the existing diked area and that the project will conform to all of the City ' s bulk storage regulations . One primary concern that the City has is with regard to proper visual screening and buffering of the site . The site is adjacent to proposed industrial park and light industrial areas and is highly visible from the residential hillside and surrounding properties . (This department concurs in the proposed declaration of non-signifi - cance , provided proper landscape screening and buffering is pro- vided around the subject site in conjunction with the special permit for a bulk storage facility required by the City of Renton . .

November 23, 1977 Mr. Mike Smith Planning Department City of Renton Renton WA 98055 Re: Mobil Oil Corporation - Bulk Storage Facility Dear Mike: I appreciate your taking the time to meet with me on Monday, November 21, 1977 , regarding Mobil' s special permit application No. SP-066-77 . As we discussed, within the last week Mobil has decided to convert one of its distilate tanks (diesel) to a gasoline tank. This conversion involves installing an internal floating roof, identical to that to be installed in the proposed new tank, and piping changes to permit product drawn from that tank to be run through the vapor recovery unit to be installed. I have discussed this matter with Mr. Gonnason of the Building Department and have reviewed the Renton Bulk Storage Ordinance. Based upon this conversation and review, I believe a building permit must be obtained from the City of Renton for this con- version. In addition, the Puget Sound Control Agency must grant approval. As we also discussed on Monday, the Environmental Protection Agency, Region IV, has accepted a modification to the manner in which one computes emissions from internal floating roof tanks. This change was based upon studies done by Chicago Bridge and Iron and the Western Oil and Gas Association. The modification to the floating roof tank emission factor results in a 75% reduc- tion in the emissions associated with tank losses. Thus , on page 2 of the Summary of the Emissions, dated 6/29/77, tankage losses are reduced to approximately 8 tons per year rather than 32 tons per year. With the conversion of the 15 , 000 barrel storage tank, noted as tank 5 on your drawings , presently used for storage Of diesel, total emissions will not rise by more than 1 ton per year upon the conversion of this tank. It is my understanding that you anticipate hearings being held on the special permit application of Mobil sometime in January, rr WATSON S-.

NAME OF PROPOSAL, IF APPLICABLE : Install 50, 000 barrel gasoline storage tank and vapor recovery unit on loading rack at Renton Terminal. I. 6 . NATURE AND BRIEF DESCRIPTION OF PROPOSAL: Tank to be internal covered floating roof type constructed according to American Petroleum Institution specification 650 . Tank to be diked and protected according to recommendations of the National Fire Protection Association No. 30. The tank will receive and store gasoline for distribution to customers. Install gasoline terminal vapor recovery system consisting of a vapor hose connection, vapor lock and vapor recovery unit. The vapor hose connection consists of four-inch diameter flexible rubber hose with female coupler at one end for connection to the vapor return line of the tank truck. During bottom filling operation, the incoming liquid gasoline displaces the vapor inside the empty tank truck and pushes it out through the vapor dome and into the vapor hose. From here, gasoline vapor mixture passes through the check valve, flame arrester and into the main vapor line. The vapor line is a pipe to convey the gasoline vapor mixture into the recovery unit. Located at the lowest portion of the vapor line is a condensate tank to collect any condensation. Any condensation on this tank is pumped out into the regular gasoline tanks. The vapor recovery unit has a vapor condensor with cooling coils that could be maintained at-90°F. The gasoli-ne vapor mixture passes through these coils where gasoline vapor condenses and collects at the water - gasoline separator tank. The cooling coils are defrosted periodically to remove water. The collected gasoline in the separator tank is transferred into one of the regular gasoline tanks. 1 . 8.

Redmond , Washington 98052 RE : ECF FOR MOBIL OIL CORPORATION INSTALLATION OF 50 , 000 BARREL GASOLINE STORAGE TANK AND VAPOR RECOVERY UNIT ON LOADING RACK AT RENTON TERMINAL • Dear Mr. Messman : This department has received and reviewed the subject environmental checklist form and the proposed declaration of non-significance issued November 10 , 1977 , by the Department of Ecology . It appears from review of the checklist that this is an addition within the existing diked tank farm area and does not represent a major expansion either within or beyond the existing diked area . It is our understanding that the applicant will include a vapor recovery system and floating tank roofs , together with all the necessary safety devices to meet City of Renton and other appli - cable standards . This will significantly reduce the environmental 'impact of the proposed project as well as the existing facility . We also understand. the proposed 50 , 000 barrel tank will be con- structed entirely within the existing diked area and that the Project will conform to all of the City ' s bulk storage regulations . One primary concern that the City has is with regard to proper visual screening and buffering of the site . The site is adjacent to proposed industrial park and light industrial areas and is highly visible from the residential hillside and surrounding properties . i This department concurs in the proposed declaration of non-signifi - cance , provided proper landscape screening and buffering is pro- vided around the subject site in conjunction with the special permit for a bulk storage facility required by the City of Renton . If you have any further questions , please contact this department . Very/trul.y yours , _ _ _jeoi G�or�do�l Y . / ri ksen �.
