ABSTRACT . - -
• . • .
A method for estimating standing-storage and withdrawal evaporation losses .
from floating-roof tanks containing crude oil or gasoline has been developed by the • .
Evaporation Loss Committee of the American Petroleum Institute. Actual field
. - test-data p:ovided the basis for the standing-storage loss correration; laboratory
• test data, which determined the adhesion of gasoline to steel surfaces in several •
stages of corrosion,provided the basis for the withdrawal loss equation. - ,-
The correlation establishes the factors necessary to predict the loss under many -
possible combinations of tank and floating-roof construction, type of roof seal, and ..-
. color of tank paint. The correlation is applicable over the ranges of 2-psia to .
( • 11-psia true vapor pressure (TVP), 4-mph to 16-mph average wind velocity, and• - -
20-ft-to 200-ft-diameter tanks. The accuracy of this method of loss estimation has • •
not been determined for higher vapor pressures or for tanks of larger diameters.
Floating-roof seals of the metallic and nonmetallic types are described. The -
manner in which evaporation loss occurs from the seal area of a floating roof is •
discussed and guidance for the selection, maintenance; 'and replacement of the • -

• • INTRODUCTION
The American Petroleum Institute sponsored a symposium on evaporation loss
at the Thirty-second Annual Meeting in 1952. 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. . •

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.

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.

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.

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.

Wel are enclosing a State Flood Control Zone application and plans
submitted to this Office by Mobile Oil Company for the construction
of a 50 , 000 gallon bulk storage tank in Section 30, Township 23
North, Range 5 East , W.M.
Wel have reviewed the proposed construction and submit the following
comments :
•
1 . For compliance with the East Side Green River
Watershed Project any structure within this
site must be flood proofed to elevation 14 .4 -
feet (Mean Sea Level Datum) .
It must be noted that until such time as the
• Green River Watershed Project is constructed
1 to the extent that it would fully serve this
property, flooding could occur at elevation
14 .4 feet and somewhat higher .
2. The existing. 100-year frequency flood plain
according to the Soil Conservation Service' s
Flood Plain Study is 21. 8 feet (MSLD) at the
subject site. The storage tanks are shown to
be flood proofed to elevation 24 . 0 feet .
However , the approval of this development on

result in a higher elevation for the 100-year
frequency flood plain because of the reduction
in the storage area for flood waters unless
improvements are made to provide for discharge
of the flood waters from the flood plain.

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 .

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.

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.

future fill and/or development, suitable landscaping
shall be provided by the applicant to bulk storage
ordinance requirements . Assurance of landscaping (A
bond shall be posted to insure landscape installation . )

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.

into, the product forms a liquid seal to 7"A TOE 8" y' /'1
positively trap the saturated vapor under (178 TO 203 WA)
the cover. 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.

creased discharge, or which will cause any of the conditions of this permit to
be exceeded, a new application must be submitted together with the necessary
reports and engineering plans for the proposed changes. No change shall be
made until plans have been approved and a new permit or permit modification
has been issued.
G3. The diversion or bypass of any discharge from the treatment works by the per-

AMENDMENTS TO ENVIRONMENTAL CHECKLIST FORM
SUBMITTED TO, THE CITY OF RENTON
1. 5. 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. LIST OF ALL PERMITS, LICENSES OR GOVERNMENT APPROVALS

Introduction The Statenvironmental Policy Act of 1971 , Chapter 43.21C, RCW, requires " ;,.-
all .jstate and local Agovernmental agencies : to consider environmental values both for their- ;-
ownlactions 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 > .
Theipurpose 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 •coinpletely as you can with the, information
presently available to you. Where explanations of your answers are required, or where
youibelieve an explanation would be helpful - to yovernment 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 with7
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 it is completed,
eve1n though completion may not occur until sometime , in the future. This will allow all
ofAhe 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 does rot apply , just answer it "no" and continue, on to the
Heil question.

Dear Mr . Wegner : �:�YG DEP1'=-
We are enclosing a State Flood. Control Zone application and plans •
submitted to this office by Mobile Oil Company for the construction
of a 50, 000 gallon bulk storage tank in Section 30, Township 23
North, Range 5 East, W.M.
We have reviewed the proposed construction and submit the following
comments :
1 . For compliance with the East Side Green River
Watershed Project any structure within this
site must be flood proofed to elevation 14 .4
feet (Mean Sea Level Datum) .
•
It must be noted that until such time as the
Green River Watershed Project is constructed
to the extent that it would fully serve this
property, flooding could occur at elevation
. _ 14 .4 feet and somewhat higher .
2. The existing 100-year frequency flood plain
according to the Soil Conservation Service's
•
Flood Plain Study is 21. 8 feet (MSLD) at the
subject site. The storage tanks are shown to
be flood proofed to elevation 24 . 0 feet .
• However , the approval of this development on
the basis of flood proofing to above the
existing 100-year frequency flood plain along
•
•
•
•
. Mr e Duane Wegner
Page two
Mobile Oil Co:
January 3 , 1978
•
•
with the approval of other applications will
result in a higher elevation for the 100-year
frequency flood plain because of the reduction
in the storage area for flood waters unless
improvements are made to provide for discharge
of the flood waters from the flood plain. •
•
3 . Additional improvements to this site •will require
State Flood Control Permits .
• If you have any questions regarding the above comments , please feel
free to contact Mr. La-ury Gibbons of this office on- 344-3874 .

=-- 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 environment61
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
;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 . .
IIf you have any further questions , please contact this department .

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,

Re: SP-066-77
'Dear Mr. Smith:
Pursuant to the agreement between the City of Renton and the
Department of Ecology that there will be a review of Mobil
Oil Corporation' s proposal to construct a 50, 000 barrel
gasoline storage tank and install a vapor recovery at its
Renton Terminal, simultaneously, I enclose an amended Envir-
onmental Checklist which references the vapor recovery unit.
You have already been presented with a booklet outlining the
vapor recovery unit in some detail. At the present time,
Mobil is preparing plans and specifications for the vapor
recovery unit to be submitted to the Building Department
pursuant to the City' s determination that only a Building
Permit must be obtained for the vapor recovery unit. Upon
completion of these drawings an application for a Building
Permit will be submitted.
If you have any questions, please feel free to contact me.

I. 5. 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. 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. LIST OF ALL PERMITS , LICENSES OR GOVERNMENT APPROVALS
REQUIRED FOR THE PROPOSAL (Federal , State and Local --
Including Rezones) :
For the 50, 000 barrel gasoline storage tank a special permit
-1-
is required from the City of Renton which has been applied for -
SP-066-77 - August 8 , 1977 . A Building Permit will be required
from the City of Renton for the vapor recovery unit which
application has not yet been made. Both units will require
approvals from the Puget Sound Air Pollution Control Agency.

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 , _ _

Attention: Mr. Stephen C. Kelly
Subject: Proposed Edwards Hydro Carbon
Vapor Recovery Unit to be
Installed by Mobil Oil Corporation
Gentlemen:
In response to your letter of July 28, 1977, we find the
unit proposed acceptable.
However, it will be the responsibility of Mobil Oil to
install a unit capable of meeting the emission standards
as established by ordinance and having this certified by
a qualified engineer.
Sincerely,
Warren C. Gonnason, P.E.
