BACKGROUND
In 1999, the Federal Energy Regulatory Commission (FERC or Commission)
referenced in its regulations the document National Bureau of Standards Information
Report (NBSIR) 84-2833 Data Requirements for Seismic Review of LNG Facilities for
seismic hazard evaluations and seismic design criteria for LNG facilities. However, this
document was published in 1984 and its seismic requirements were based on the version
of Title 49 of the Code of Federal Regulations (CFR), Part 193 (49 CFR Part 193) that
existed and the edition of National Fire Protection Association (NFPA) Standard 59A that
was referenced by 49 CFR Part 193 at that time.
DOT regulations under 49 CFR 193 largely went unchanged from 1980 until 1999.
After 1999, DOT changed substantial portions of their regulations. When the Commission
received applications for liquefied natural gas (LNG) import terminals in the early- and
middle-2000s, we therefore developed a series of guidance documents to assist project
sponsors preparing applications to satisfy our regulations and needs to evaluate the safety
of the proposed projects. On December 15, 2005, we issued Draft Guidance on Resource
Report 11 and 13 to assist project sponsors in interpreting regulations under
18 CFR §380.12(m) and 18 CFR §380.12(o) for LNG applications. On April 12, 2006, we
issued the Draft Preferred Format Submittal Guidance to recommend the format of
submitted material to make our review more efficient. Finally, on January 23, 2007, we
issued the Draft FERC Seismic Design Guidelines and Data Submittal Requirements for
LNG Facilities in recognition that new U.S. Department of Transportation (DOT
requirements in 2003 adopted the 2001 edition of National Fire Protection Association
(NFPA) Standard 59A.
The Draft Guidance on Resource Report 11 and 13 and Draft Preferred Format
Submittal Guidance were based upon what was understood to be the requirements of Title
49 CFR Part 193, incorporated references (e.g., NFPA 59A), and practices of LNG
facilities at the time. However, since then, a number of LNG project proposals have
necessitated our evaluation of distinct hazards and potential safety impacts. In addition,
we participated in a number of studies with the Fire Protection Research Foundation,
Department of Energy, Coast Guard, and Department of Transportation to better address
these hazards and potential safety impacts. In 2010, we assisted DOT in issuing additional
interpretations on the requirements to meet the exclusion zones and siting requirements in
49 CFR Part 193 and in 2011 assisted DOT in evaluating and approving additional hazard
modeling programs to demonstrate compliance with the 49 CFR Part 193 siting
regulations. Accordingly, we have refined and clarifed the level of information needed for
our evaluation of the hazards associated with proposed LNG facilities per 18 CFR
§380.12(m) and 18 CFR §380.12(o).

Similarly, Draft FERC Seismic Design Guidelines and Data Submittal
Requirements for LNG Facilities has benefited from years of application and were based
on DOT requirements for seismic evaluations, which have since changed. The current
seismic requirements for LNG facilities in DOT regulations under 49 CFR Part 193
incorporate by reference NFPA 59A-2006 and NFPA 59A-2001. NFPA 59A-2006 is only
applicable to stationary LNG storage tanks to be seismically designed for the safe shutdown
earthquake (SSE) and operating basis earthquake (OBE) design earthquake ground
motions. NFPA 59A-2001 requires piping with cold contents (−20 °F or lower) to be
designed dynamically for the OBE or statically 0.60 SDS (maximum spectral acceleration
of the design earthquake which equals 2/3 of the maximum considered earthquake [MCE])
as specified in the National Earthquake Hazards Reduction Program (NEHRP)
Recommended Provisions. NFPA 59A-2001, Appendix B.5.2, refers seismic design for the
remainder of the LNG facilities to NEHRP Recommended Provisions, but these are in nonmandatory Appendix B. We also recognize the current FERC regulations under
Title 18 CFR §380.12(h)(5) continues to incorporate NBSIR 84-2833. NBSIR 84-2833
provides guidance on classifying stationary storage containers and related safety equipment
as Category I and classifying the remainder of the LNG project structures, systems, and
components as either Category II or Category III, but does not provide specific guidance
for the seismic design requirements for them. Absent any other regulatory requirements,
this guidance recommends that other LNG project structures classified as Seismic Category
II or Category III be seismically designed to satisfy the seismic requirement of the
American Society of Civil Engineers (ASCE) 7-05 1 in order to demonstrate there is not a
significant impact on the safety of the public. ASCE 7-05 is recommended as it is a
complete American National Standards Institute (ANSI) consensus design standard, its
seismic requirements are based directly on the NEHRP Recommended Provisions, and it
is referenced directly by the International Building Code (IBC). Having a link directly to
the IBC and ASCE 7 is important to accommodate seals by the engineer of record because
the IBC is directly linked to state professional licensing laws while the NEHRP
Recommended Provisions are not. Taken together, this Guidance Manual is based upon the
regulatory requirements of 18 CFR §380.12, 49 CFR Part 193, and provisions in ASCE 7
and other best practices to demonstrate that the potential hazard to the public from failure
of facility components resulting from natural catastrophes is addressed and that there would
not be a significant impact on public safety from seismicity and other natural hazards at
LNG facilities.

1

This guidance is based on the current version 49 CFR Part 193 that was applicable at the time of its writing and
is therefore consistent with NFPA 59A – 2006 for determination of seismic design ground motions. The
determination of seismic ground motions using the detailed procedures of ASCE 7-05 are consistent with the
seismic design ground motions defined in NFPA 59A – 2006 and are therefore utilized in this document. This
guidance does not supersede or alleviate an applicant of meeting 49 CFR Part 193 or any subsequent revisions
made to 49 CFR Part 193.

INTRODUCTION

We 2 provide this Guidance Manual to describe information in an application for a
LNG project to evaluate and address potential safety and reliability impacts and include
related engineering design information 3. This document combines, replaces, and updates
the Guidance for Filing Resource Reports 11 & 13 for LNG Facility Applications (Dec.
2005), Resource Report 13 Draft Preferred Submittal Format Guidance (Apr. 2006), and
the Draft Seismic Design Guidelines and Data Submittal Requirements for LNG Facilities
(Jan. 2007).
This manual does not substitute for, amend, or supersede the Commission’s
regulations under the Natural Gas Act of 1938 (NGA) or the Commission’s and Council
on Environmental Quality’s (CEQ) regulations under the National Environmental Policy
Act of 1969 (NEPA). It imposes no new legal obligations and grants no additional rights.
To the extent practicable, we use non-mandatory language such as “recommend,”
“encourage,” and “may” to describe Commission staff’s recommendations. We use
mandatory language such as “required,” “must,” and “must not” to describe controlling
requirements under the terms of statutes and regulations. The manual discusses our
preferred format for certain documents and data presentation. However, applicants can use
an alternative approach if it satisfies the requirements of the applicable statutes and
regulations.
The purpose of Volume II is to facilitate our review and to assist applicants by
identifying the specific information and level of detail and formatting recommended for
Resource Report 11 and Resource Report 13 submitted in applications for LNG projects.
These Resource Reports are required are required for proposals for new LNG facilities,
expansions of existing LNG facilities, or re-commissioning of existing LNG facilities per
Title 18 of the Code of Federal Regulations (CFR) Section 380.12 (18 CFR §380.12). The
resource reports must contain the type of site-specific design information produced in the
normal course of developing the design of an LNG project. The resource reports usually
would not require abnormal details or special drawings generated solely for the
Commission unless novel designs require additional detail or we request further detail.

“We,” “us,” and “our” refer to the environmental staff of the Federal Energy Regulatory Commission’s Office of
Energy Projects. “You,” whether explicit or implied, refers to the applicant proposing a natural gas project or to
the applicant’s agent(s) who prepares, uses, or reviews these types of environmental documents.
See Title 18, Chapter I of the Code of Federal Regulations (CFR) §380.12(h)(5), 18 CFR §380.12(m), and 18 CFR
§380.12(o) of the Commission’s regulations, which appear throughout this document. The Commission’s
regulations in part 380 implement the National Environmental Policy Act of 1969, with section 380.12
specifically addressing Environmental Reports for applications under the Natural Gas Act. Similarly, other
agencies’ regulations include a full citation, such as 49 CFR Part 193 issued by the Pipeline and Hazardous
Materials Safety Administration within the U.S. Department of Transportation.

Commission Staff Guidance

Resource Report 11 addresses the potential hazard if facility components were to
fail due to accidents or natural catastrophes, how these events would affect reliability and
safety, and the procedures and design features that applicants would use to reduce potential
hazards. Resource Report 11 should serve as a public summary that we can use to prepare
our environmental document under NEPA. Resource Report 13 contains more detailed
information that supports the summarized information in Resource Report 13, which we
use to verify whether the engineering design ensures adequate reliability and safety.
The level of detail to be submitted in Resource Report 13 varies based on the phase
of project development. We intend to provide our input early enough in the design phase
to influence the reliability and safety provisions considered in the design while minimizing
associated costs with changes as shown in the relationship in Attachment 1. No matter the
phase of the project development, the level of detail should include all features necessary
to evaluate the design, construction, commissioning, start-up, operation, and maintenance
of the facilities as identified in this guidance. The level of detail at the time of pre-filing is
typically reflective of a front end engineering design (FEED) still in development. The
level of detail at the time of application is typically reflective of a completed FEED. We
do not expect details about the final design at the time of application, but note that this
guidance also includes information that may become available during the final design
phase, as indicated by an asterisk (*). The development of final design information should
be discussed as identified in this guidance, but would not be expected to be developed at
the time of application.
Detailed information filed on the engineering design may qualify as Critical Energy
Infrastructure Information (CEII) and privileged material. All filings must be made in
compliance with the 18 CFR Part 388 of the Commission’s regulations concerning CEII
and privileged material. If providing separate binders or electronic filings for public, CEII,
and privileged versions, then the privileged version should be a complete resource report
for review that includes all public and CEII information. Any CEII or privleged material
should be filed as non-public and labeled “Contains Privileged Information – Do Not
Release” (18 CFR §388.112) or “Contains Critical Energy Infrastructure Information
– Do Not Release” (18 CFR §388.113) and should be filed separately from the remaining
information which should be marked “Public.”

Filings
We issue this Guidance Manual to broadly address all types of LNG projects.
Because each project is unique, some topics may not be appropriate for the scope of a
proposed project or may not apply at all. Where a topic does not apply to the proposed
facilities, applicants should note that the topic is “Not applicable” in the filing. If the
applicant wishes to add to the list of topics, the applicant should make the addition at the
end of the list and not as an insert.
The filings should include a complete set of drawings in electronic and hard copy
format to FERC LNG staff as part of the submitted application.
Hard copies of drawings should be on 11”x17” paper in three-ring binders. The
drawings must be legible (e.g., hard copies of colored drawings are to be printed in color,
not black and white) with a title block and not folded. The drawings should be preceded by
a master index on 8.5” x 11” paper that lists drawing number, drawing name, revision date,
and revision number. Hard copies should be placed in separate binders in the format order
recommended in this guidance and be separated for each Appendix. Each binder volume
should be labeled, numbered, and ordered with a master index of the entire Resource
Report contents. The spine of each volume should also be labeled, numbered, and ordered
to reflect the contents.
Electronic copies of drawings should be filed in .pdf or .docx formats. The drawings
must be legible, and the textual content should be searchable. The drawings should be
preceded by a master index that lists drawing number, drawing name, revision date, and
revision number matching the hard copies. Electronic copies should be bookmarked and
separated into distinct electronic documents for the main text of Resource Report 11, for
the main text of Resource Report 13, and for each Appendix.

Hot and cold temperature hazards are typically limited by the heat transfer characteristics of the fluid. Direct
contact with liquids, surfaces of equipment, or direct exposure to high momentum vapors at the release location
tend to produce high enough heat transfer rates compared to vapors dispersing in low wind conditions.
Referencing of properly designed spill containment and structural supports in Resource Report 13 is satisfactory
to demonstrate these hot and cold temperature hazards from liquid spills will not impact the safety or reliability
of the facilities. Referencing of properly designed piping and equipment thermal insulation in Resource Report
13 is satisfactory to demonstrate direct contact with surfaces of equipment would not pose a hazard. Referencing
of properly done hazard modeling that shows hot and cold temperatures would not extend offsite or onto
equipment or structural supports in Resource Report 13 is satisfactory to demonstrate hot and cold temperatures
from vapor releases will not impact the safety or reliability of the facilities. The modeling should show this by
tracking the temperature directly or by tracking the concentrations and correlating the concentrations with
temperatures.
This may include distinct hazards for DOT’s regulations at 49 CFR Part 193 and/or worst case and alternative
scenarios for EPA’s regulations at 40 CFR Part 68, as applicable.

Where flammable endpoint concentrations or toxic endpoint concentrations are less than asphyxiation endpoint
concentrations and are modeled and shown to not impact the public, there does not need to be further
demonstration that higher asphyxiation concentrations would also not impact the public as the dispersion distance
of a lower concentration will encompass the dispersion distance of a higher concentration.

predetermined results of analyses that predict when damage might
occur. This also permits plant operators to understand the possible
extent of damage within the plant immediately following an earthquake
and to be able to determine when an SSE event has occurred that would
require the emptying of the tank(s) for inspection as specified in Section
4.1.3.6 (c) of NFPA 59A-2001. If the instrument already exists at the
site, include a description of the existing equipment and location of the
instrument and the sensors. The seismic instrumentation section should
be in accordance with NBSIR 84-2833. Seismic recording
instrumentation should be triaxial digital systems that record

seconds. Recorders should have rechargeable batteries such that if there
is a loss of power, recording will still occur. The instrumentation should
be housed in appropriate weather and creature-proofed enclosures. At
all LNG facilities, at a minimum, one recorder should be located in the
free field mounted on rock or competent ground generally
representative of the site. In addition, at sites classified as Seismic
Design Category D, E, or F in accordance with Chapter 11 of ASCE 705 (assuming Occupancy Category IV) recorders should be located and
attached to the foundations and roofs of LNG tanks, and in the control
room. The systems should have the capability to also produce response
spectra for each recorded time history. At a minimum, the seismic

guidelines for typical LNG projects. Depending on the site conditions or soils encountered,
some type of investigations, such as CPTs in dense gravelly soils or rock coring at soil
sites, may not be needed
Typically a minimum of 5 borings/CPTs should be performed at each LNG tank
location. In each Liquefaction Train area and other process areas the borings/CPTs should
be spaced at a minimum of 200 to 300 foot spacing. It is suggested that a proposed
boring/CPT plan be submitted to FERC for review prior to undertaking the field
investigation. Geotechnical information should be supplied that is needed to establish the
Site Class in accordance with Chapters 11 and 20 of ASCE 7-05. Evaluations should also
be supplied that predict how the geotechnical information will change for any ground
improvement options that are recommended in the report. Site Classes should be
determined and supplied for all Seismic Category II and III structures at the site based on
Chapters 11 and 20 of ASCE 7-05 for the various ground improvement options that are
included in the report. Subsidence due to earthquake, ground water, and oil withdrawal
should also be evaluated. Presence of poor or unusual soil conditions, such as highly

EVALUATION CONTENTS
1.

General

A seismic ground motion hazard analysis study should be performed to determine
the site-specific OBE and SSE ground motions in accordance with 49 CFR Part 193 and
the incorporated NFPA 59A requirements and to determine the MCE and DE ground
motions in accordance with the incorporated ASCE 7 requirements.
In addition to the specific data needed to support and justify the site-specific ground
motion recommendations, the study should include geologic and seismic data requested in
this Attachment and a discussion of other seismic hazards such as fault rupture, tsunamis,
and seiche.
The geotechnical report should address in detail the following hazards, if present,
and the need for ground improvement to mitigate them: liquefaction potential, liquefactionrelated settlement, potential for sand boils and other surface manifestation of liquefaction,
lateral spreading, seismic slope stability, and seismic compaction. Follow the outline in
Attachment 6.
2.

Geology

In addition to standard geotechnical information needed to develop foundation
recommendations, the additional geologic information requested herein should be provided
in the seismic ground motion hazard study report. Information obtained from published
reports, maps, private communications, or other sources should be referenced. Information
from surveys, geophysical investigations, borings, trenches, or other investigations should
be adequately documented by descriptions of techniques, graphic logs, photographs,
laboratory results, identification of principal investigators, and other data necessary to
assess the adequacy of the information.
2.1

Regional Geology

Discuss all geologic, seismic, and manmade hazards within the site region and relate
them to the regional physiography, tectonic structures and tectonic provinces,
geomorphology, stratigraphy, lithology, and geologic and structural history and
geochronology. This information should be discussed and shown on maps needed to
illustrate actual or potential hazards such as landslides, subsidence, uplift, or collapse
resulting from natural features such as tectonic depressions and cavernous or karst terrains
that are significant to the site.
Identify and describe tectonic structures such as folds, faults, basins, and domes
underlying the region surrounding the site, and include a discussion of their geologic
history. A regional tectonic map showing the structures of significance to the site should

Februrary 2017

be provided. The detailed analyses of faults to determine their capacity for generating
ground motions at the site and to determine the potential for surface faulting should be
included. Refer to Section 3 of this Attachment for additional detail.
Provide geologic profiles showing the relationship of the regional and local geology
to the site location. The geologic province within which the site is located and the relation
to other geologic provinces within 100 miles of the site should be indicated. Regional
geologic maps indicating the site location and showing both surface and bedrock geology
should also be included.
2.2

Site Geology

A site topographic map showing the locations of the principal plant facilities should
be included. Regional hazard identified in Section 2.1, e.g., landslides, should be evaluated
for the site. The thicknesses, physical characteristics, origin, and degree of consolidation
of each lithologic unit should also be described for the site, including a local stratigraphic
column. Furnish summary logs of borings and excavations such as trenches used in the
geologic evaluation. Boring logs included in Attachment 6, Section 2.1, may be referenced.
A detailed discussion of the structural geology in the vicinity of the site should be
provided with particular attention to specific structural units of significance to the site such
as folds, faults, synclines, anticlines, domes, and basins. Provide a large-scale structural
geology map (1:5,000) of the site showing bedrock surface contours and including the
locations of Seismic Category I structures. A large-scale geologic map (1:24,000) of the
region within 5 miles of the site that shows surface geology and that includes the locations
of major structures of the LNG plant, including all Seismic Category I structures,
embankments, and pipelines should be described in detail. Areas of bedrock outcrop from
which geologic interpretation has been extrapolated should be distinguished from areas in
which bedrock is not exposed at the surface. When the interpretation differs substantially
from the published geologic literature on the area, the differences should be noted and
documentation for the new conclusions presented.
Include an evaluation from an engineering-geology standpoint of the local geologic
features that affect the plant structures. Deformational zones such as shears, joints,
fractures, and folds, or combinations of these features should be identified and evaluated
relative to structural foundations. Describe and evaluate zones of alteration or irregular
weathering profiles, zones of structural weakness, unrelieved residual stresses in bedrock,
and all rocks or soils that might be unstable because of their mineralogy or unstable
physical or chemical properties. The effects of man's activities in the area of the site should
be evaluated; for example, withdrawal or addition of subsurface fluids or mineral
extraction. Site groundwater conditions should be described.

Faulting

3.1

Investigation of Quaternary Faults

Identified faults, any part of which is within 5 miles of the site, should be
investigated in sufficient detail, using geological and geophysical techniques of sufficient
sensitivity that demonstrate the age of the most recent movement on each. The type and
extent of investigation varies from one geologic province to another and depends on sitespecific conditions.
For Quaternary faults, any part of which is within 5 miles of the site, determine the
following:
1)
2)
3)
4)
3.2

length of the fault;
relationship to regional tectonic structures;
nature, amount, and geologic displacement along the fault; and
outer limits of the fault zone.

Determination of Active Faults

Determine the geologic evidence of fault offset at or near the ground surface at or
near the site. Any lineaments identified on topographic maps, aerial photos, or satellite
imagery linears identified as part of this study should be discussed.
List all historically reported earthquakes that can be reasonably associated with
faults, any part of which is within 5 miles of the site. A plot of earthquake epicenters
superimposed on a map showing the local tectonic structures should be provided.
The structure and genetic relationship between the site area faulting and regional
tectonic framework should be discussed. In tectonically active regions, any detailed
geologic and geophysical investigations conducted to demonstrate the structural
relationships of site area faults with regional faults known to be seismically active should
be discussed.
3.3

Fault Rupture Investigation

A detailed faulting investigation should be conducted within one mile of the storage
tank(s) foundation(s) and, as necessary, along any active faults identified under Section 3.2
of this Attachment that reasonably have a potential for affecting faulting on the site or
provide significant information concerning such faulting. This investigation should be in
sufficient detail to determine the potential for faulting and the magnitude of possible
displacement impacting the safety-related facilities of the plant. The report of the faulting
investigation should be coordinated with the investigation and report under Sections 3.1
and 3.2 of this Attachment and should include information in the form of boring logs,

Commission Staff Guidance

February 2017

detailed geologic maps, geophysical data, maps and logs of trenches, remote sensing data,
and seismic refraction and reflection data. If faulting exists, it should be defined as to its
attitudes, orientations, width of shear zone, amount and sense of movement, and age of
movements. Site surface and subsurface investigations conducted to determine the absence
of faulting should be reported, including information on the detail and areal extent of the
investigation. The geologic studies included in a Fault Rupture Investigation should
conform to established guidelines such as California Division of Mines and Geology, Note
49 (Ref. 22).
Based on geologic studies, if it is determined that there is a potential for fault rupture
hazard, and the structure is to be located either within 500 feet of a known fault or the
possibility of a fault rupture passing through the proposed structure cannot be excluded,
then seismic fault rupture analysis should be performed. This may include, but not be
limited to magnitude, slip rates and recurrence models, type of fault (e.g., strike slip,
normal), horizontal and vertical components of offset, and style of faulting.

Ground Motions

4.1

Historic Seismicity

A complete list of all historically reported earthquakes affecting the region
surrounding the site should be provided. The listing should include, as a minimum, all
earthquakes of Modified Mercalli Intensity greater than IV or magnitude greater than 3.0.
A map should also be provided that shows all listed earthquake epicenters. The following
information describing each earthquake should be provided whenever it is available:
1)

epicenter coordinates,

2)

depth of focus,

3)

origin time,

4)

highest intensity,

5)

magnitude (including moment magnitude),

6)

source mechanism,

7)

source dimensions,

8)

stress drop,

9)

any strong motion recordings relevant to a determination of the ground
motion or design response spectra, and

10)

references from which the specified information was obtained.

Commission Staff Guidance

A-6

February 2017

In addition, any earthquake-induced geologic hazards (e.g., liquefaction,
landsliding, land spreading, or lurching) that have been reported on or within 5 miles of
the site should be described in detail, including the level of strong motion that induced
failure and the properties of the materials involved.
This discussion should include identification of the methods used to locate the
earthquake epicenters and an estimate of their accuracy.
4.2

Geologic Structures and Tectonic Activity

Identify the regional geologic structures and tectonic activity that are significant in
determining regional earthquake potential. All tectonic provinces any part of which could
govern the design ground motions at the site should be identified. The identification should
include a description of those characteristics of geologic structure, tectonic history, present
and past stress regimes, and seismicity that distinguish the various tectonic provinces and
particular areas within those provinces where historical earthquakes have occurred.
Alternative models of regional tectonic activity from available literature sources should be
discussed. The discussion in this section should be augmented by a regional-scale map
showing the tectonic provinces, earthquake epicenters, the locations of geologic structures
and other features that characterize the provinces, and the locations of any Quaternary
faults.
When an earthquake epicenter cannot be reasonably correlated with geologic
structures, the epicenter should be discussed in relation to tectonic provinces. Subdivision
of tectonic provinces should be supported on the basis of evaluations that consider, but
should not be limited to, detailed seismicity studies, differences in geologic history, and
differences in stress regime.
4.3

Maximum Earthquake Potential

The largest earthquake or earthquakes associated with each geologic structure or
tectonic province should be identified. Where the earthquakes are associated with a
geologic structure, the largest earthquake that could occur on that structure should be
evaluated based on considerations such as the nature of faulting, fault length, fault
displacement, and earthquake history. The largest historical earthquakes within the
province should be identified and, whenever reasonable, the return period for the
earthquakes should be estimated. A table of faults with fault length, type of fault, distance
at closest point to the site, maximum earthquake, etc. should be provided.
4.4

Near-Fault Effects

For each set of conditions describing the occurrence of the maximum potential
earthquakes, determined in Section 5.3 above, the types of seismic waves (such as

Commission Staff Guidance

A-7

February 2017

directivity, fault normal, and fault parallel) producing the maximum ground motion and
the significant frequencies at the site should be determined.
4.5

Determination of Site Class

Site Class definitions are provided in ACSE 7-05 (Chapter 20) or IBC 2006 (Table
1613.5.2). Site classes range from Class A for hard rock to Class F for liquefiable or other
very poor soil conditions. Site Class should be determined by seismic velocity data and
other geotechnical data provided in the geotechnical report in accordance with the
procedure in Sections 1613.5.5 and 1613.5.5.1 of IBC 2006 or Chapter 20 of ASCE 7-05.
4.6

Deterministic Seismic Hazard Analysis

A deterministic seismic hazard analysis should be performed which computes the
peak ground horizontal acceleration and spectral response accelerations for periods of at
least 0.2s and 1.0s from the maximum earthquake on each of the faults found within 100
miles from the site. The computation of the peak acceleration and spectral accelerations is
based on the closest distance between the site and each fault and the selected attenuation
relationships. In general, a minimum of three attenuation relationships should be used
consistent with the geologic and seismic setting of the site and type of faulting. The closest
active fault and the fault generating the maximum acceleration at the site should be
identified. Differences between the selected attenuations and the attenuations used in the
latest USGS National Seismic Hazard Maps should be discussed.
4.7

Probabilistic Hazard Analysis

Probabilistic seismic hazard evaluation involves obtaining, through a formal
mathematical process, the level of ground motion parameters that have a selected
probability of being exceeded during a specified time interval.
The probabilistic approach incorporates the contributions from historical seismicity
and all faults and considers the likelihood of the occurrence of earthquakes at any point on
the fault. It also incorporates the contributions from various magnitude earthquakes up to
and including the maximum earthquake. This approach is described in a number of sources
such as Cornell, 1968 (Ref. 25), Algermissen et al, 1976 (Ref. 27) and Frankel, 1996, 2002
(Ref. 26).
A probabilistic seismic hazard analysis should be performed using at least three
attenuation relationships consistent with the geologic and seismic setting of the site.
Differences between the selected attenuations and the attenuations used in the latest USGS
National Seismic Hazard Maps should be discussed. Based on the site-specific probabilistic
analyses, two levels of site ground motions, the OBE and SSE ground motions should be
developed in accordance with the guidelines provided in Section 5.2 of Part I of this
document.

4.8

Code Values of Ground Motions

The code values of ground motions should be determined using either ASCE 7-05
or IBC since both of these yield identical results. Two levels of shaking are identified as
follows:
Maximum Considered Earthquake (MCE) Ground Motion
MCE ground motions have a 2 percent probability of exceedance within a 50-year
period (2475-year return period) with deterministic limits. These ground motions may be
read from the published maps in ASCE 7-05 or IBC adjusted for site class. These ground
motions may also be obtained using a ground motion calculator that is available at the
USGS web site (http://earthquake.usgs.gov/research/hazmaps/design/). A site-specific
MCE may be developed in accordance with Chapter 21 of ASCE 7-05 including the 80%
limits.
Design Earthquake (DE) Ground Motion
DE ground motions are 2/3 of the MCE motions as defined above adjusted for Site
Class.

Supporting Elements and Enclosures

A structure, component, or system of a given Seismic Category may be supported
or enclosed by a structure classified in a different category, provided it is demonstrated that
the supported item can maintain its functional requirements specified by its Seismic
Category.
3.

Seismic Performance Goals by Category
The following are the seismic performance goals for each category:

3.1

Seismic Category I

At a minimum and in accordance with 49 CFR Part 193 and incorporated NFPA
59A, these structures, components and systems should be designed to remain operable
during and after the OBE design ground motion (NFPA 59A, 2006 edition, Section 7.2.2.5
A). The design should provide for no loss of containment capability of the primary
container and it should be possible to isolate and maintain the LNG container during and
after the SSE design ground motion (NFPA 59A, 2006 edition, Section 7.2.2.6 D).
At a minimum and in accordance with 49 CFR Part 193 and incorporated NFPA
59A, the impounding system should be designed to withstand an SSE while empty and an
OBE while holding maximum operating volume of the LNG container (NFPA 59A, [2001
edition], Section 4.1.3.2 and NFPA 59A, [2006 edition], Section 7.2.2.6). After an OBE or
SSE, there should be no loss of containment capability (NFPA 59A, 2001 edition, Section
4.1.3.4 and NFPA 59A, 2006 edition, Section 7.2.2.7).
3.2

Seismic Category II

At a minimum and in accordance with 49 CFR Part 193 and incorporated NFPA
59A, piping systems and components for flammable liquids and gases and service
temperatures below −20 °F should be designed to withstand an OBE (NFPA 59A, [2001
edition], Section 6.1.1 and 6.1.2). These systems and components should be designed to
meet the seismic performance goals of the IBC for “hazardous” facilities. For hazardous
facilities, it is expected that the damage from the DE ground motion defined in the
incorporated ASCE 7 would not be so severe as to preclude continued occupancy and
function of the project facilities.
3.3

Seismic Category III

These structures, components and systems should be designed to meet the seismic
performance goals of the IBC and ASCE 7 for normal “non-essential” facilities. For normal
facilities, it is expected that structures designed and constructed according to ASCE 7,
would sustain repairable damage when subjected to DE ground motions although it may
not be economical to do so.

the use of plan and elevation drawings in sufficient number and detail to provide a
reasonable understanding of the general layout of the plant. The sizes and loading of the
critical structures should be provided.
1.2

Summary of Site Investigation and Project Status

The current status of the site evaluation study should be documented and additional
planned investigations should also be described. The current design status of the project
should include whether the phase of design, such as conceptual design or final design, and
should identify what level of computations have been performed to arrive at the current
design stage and what studies, data gathering, calculations and documentation remains to
be done. Such items as unusual site characteristics, solutions to particularly difficult
engineering problems, and significant extrapolation in technology represented by the
design should be highlighted.
2.

Exploration

Discuss the type, quantity, extent, and purpose of all explorations. Provide plot plans
that graphically show the location of all site explorations such as borings, trenches, borrow
pits, seismic lines, cone penetration tests, piezometers, wells, geologic profiles, and the
limits of required construction excavations. The locations of the Seismic Category I, II,
and III facilities should be superimposed on the plot plan. Also, furnish selected geologic
cross-sections and profiles that indicate the location of borings and other site exploration
features, groundwater elevations, and final foundation grades. The location of safetyrelated foundations should be superimposed on these sections and profiles.
Logs of all borings and test pits should be provided. Furnish logs and maps of
exploratory trenches and geologic maps and photographs of the excavations for the
facilities of the LNG plant.

(RQD), and blow counts from standard penetration tests. Provide specific details of how
the Standard Penetration Test was performed. Discuss drilling and sampling procedures
and indicate where samples were taken on the logs. In areas where liquefaction potential is
high, borings should be performed by rotary drilling method in accordance with the
requirements for obtaining standard penetration blow count N-values outlined by Youd, et
al., 2001 (Ref.11) and Martin & Lew, 1999 (Ref. 21). Cone penetration tests should be
performed to define the soil profile accurately and to use both N-values and CPT data for
evaluation of liquefaction potential and settlements due to liquefaction. Typically a
minimum of five (5) explorations (borings / CPTs) should be performed under each LNG
tank and the depth of the exploration should be 20 feet deeper than deepest anticipated
foundations. The borings and CPTs should also be sufficiently deep to sample the zone of
influence for settlements and liquefaction potential (at least 100 feet if bedrock is not
encountered). For large tanks more than 5 explorations may be necessary to adequately
characterize the sub-surface conditions.
All local, state, and Federal environmental regulations regarding obtaining permits
for the geotechnical borings and wells, clearing of underground utilities, disposal of
cuttings and drilling mud should be followed.
Where groundwater is present at depths which could affect the foundations or
liquefaction potential, selected borings should be converted into wells to define stabilized
groundwater. Historic high groundwater should be determined from published literature
for liquefaction evaluation.
2.2

Geophysical Surveys

Results of compressional and shear wave velocity surveys performed to evaluate the
occurrence and characteristics of the foundation soils and rocks should be provided in
tables and profiles. Discuss other geophysical methods used to define foundation
conditions. The depth of explorations for performing downhole or cross-hole shear wave
velocity measurements should be at least 100 feet.

should be tabulated for bearing capacity, settlement, pile capacity, and slope stability
calculations. The basis for selected soil parameters (laboratory testing, blow counts, CPT
data, experience) should be stated. A discussion on the selection of engineering parameters
is required. When published correlation relationships are used to determine the engineering
parameters, references should be given.
A conversion ratio between blow counts from penetration tests not performed per
ASTM D 1586 (standard penetration test) should be discussed and provided, if applicable.
This includes nonstandard samplers, nonstandard hammer energy delivery systems, and
considerations of hammer efficiency.
5.3

Groundwater Conditions
The analysis of groundwater at the site should include the following points:
1)

A discussion of groundwater conditions relative to the stability of Seismic
Category I safety-related facilities;

2)

A discussion of design criteria for the control of groundwater levels or
collection and control of seepage;

3)

Requirements for dewatering during construction and a discussion of how
dewatering will be accomplished;

4)

Records of field and laboratory permeability tests;

5)

History of groundwater fluctuations, including those due to flooding and
recommended design groundwater level for the plant and for liquefaction
analyses;

6)

Information related to the periodic monitoring of local wells and
piezometers;

7)

Direction of groundwater flow, gradients, and velocities; and

8)

Discussion of or reference to the groundwater monitoring program during
the life of the plant to assess the potential for subsidence.

Seismic Hazards

Seismic hazards include fault rupture, ground motions, liquefaction, lateral
spreading, seismic slope stability, seismic compaction, tsunamis and seiche. Details of fault
rupture, ground motions, tsunamis, and seiche, should be provided in the site-specific
seismic ground motion report. These items should be summarized in the geotechnical
report.
Liquefaction potential, liquefaction-related settlement, potential for sand boils and
other surface manifestation of liquefaction, lateral spreading, seismic slope stability,
seismic compaction, and need for ground improvement to mitigate these hazards, if present,
should be addressed in detail in the geotechnical report.
6.1

Fault Rupture

Distances from significant faults should be identified and potential for fault rupture
should be discussed in the geotechnical report. The site-specific ground motion report
should be referenced for more details.
6.2

Site Class
Site Class should be identified per ASCE 7 or IBC.

Commission Staff Guidance

A-23

February 2017

6.3

Ground Motions

A seismic hazard study should be performed to establish ground motions for the site
for four levels of shaking, the OBE, the SSE, the MCE, and the DE. Details of the
requirements for the determination of the ground motions are presented in Attachment 3.
6.4

Seismic Slope Stability

The LNG tanks should have a minimum calculated static factor of safety of 1.5 for
slope stability with respect to any nearby slopes of berthing slips or other existing or future
slopes. Pseudo-static screening analyses may be used to determine seismic slope stability,
provided the soils are not liquefiable or expected to lose shear strength significantly during
deformation. Detailed deformation analyses should be performed where pseudo-static
screening analyses indicate that factor of safety is less than 1.0.
6.5

Liquefaction Evaluation

When the field investigation reveals that potentially liquefiable soils and conditions
including lateral spreading exist and they pose a hazard to the project site, a quantitative
geotechnical evaluation of such a potential should be conducted. In-situ testing, soil
sampling, and laboratory testing on potentially liquefiable soils must be properly planned
and conducted to obtain reliable data for the geotechnical evaluation. If liquefaction is
likely to occur, its consequences should be assessed, its impact on foundations should be
addressed, and mitigation measures should be specified. Elevations of the liquefiable
layer(s) should be presented in the Foundation Report. Assumptions, analytical or
empirical methods used, and conclusions for liquefaction evaluation should be stated with
relevant data and analysis attached in Appendices. Potential for surface manifestation of
liquefaction in form of sand boils and surface displacement should be identified. Total and
differential settlements due to liquefaction should be estimated and provided. If
liquefaction settlements are beyond the tolerance of the proposed structures, remedial
measures to mitigate liquefaction potential should be provided. All liquefaction evaluations
should be performed in accordance with latest published guidelines (e.g., Youd, T. L., et.
al., 2001 (Ref. 11), and Martin, G. R., and Lew, M., 1999 (Ref. 21)).
6.6

Lateral Spreading

If liquefaction potential exists, potential for lateral spreading should be evaluated
and calculations of lateral movements made by Newmark simplified approach (Makdisi,
F. I., and Seed H.B, 1978 and by Bartlett & Youd (1995)) method. The effects of calculated

Commission Staff Guidance

A-24

February 2017

lateral spreading movements on the stability of the plant structures should be evaluated and
remedial measures proposed, if the movements exceed the design criteria.
6.7

Subsidence

Subsidence due to earthquakes, groundwater or oil withdrawal is a significant
geologic/seismic risk. Areal movements due to these effects should be evaluated and their
effects on the differential settlement of the plant structures, or general effects on the site
(e.g., should be evaluated.
7.

Poor Soil Conditions

Presence of poor or unusual soil conditions, such as highly compressible or highly
expansive soils, corrosive soils, collapsible soils, erodible soils, liquefaction-susceptible
soils, frost heave susceptible soils, frozen soils, or sanitary landfill etc. should be identified
and remedial measures including ground improvement methods should be recommended,
if such soils are present.
8.

Foundation Recommendations

Complete, concise, and definite foundation recommendations should be provided
for various categories (Seismic Categories I, II, and II) structures. The selection of a
specific foundation type depends on factors such as surface and subsurface conditions at
the site, geotechnical capacity, dynamic and static demands, environmental concerns,
economics, and construction issues. The recommended foundation type should be costeffective, performance-proven, and constructible.
Alternative foundation types should be discussed and the reasons why those
alternatives are not recommended should be stated. Solutions to potential construction
problems should be discussed. A sufficient and adequate geotechnical evaluation for the
recommended foundation should be performed.
In general, any foundation design should meet four essential requirements: (1)
adequate geotechnical capacity of soil/rock surrounding the foundation with a specified
safety against ultimate failure; (2) acceptable total or differential settlements under static
and dynamic loads; (3) adequate overall stability of slopes in the vicinity of a footing/mat;
and (4) constructability with solutions for anticipated problems.
8.1

LNG Tanks

8.1.1 Tank Loading and Settlement Criteria
For LNG tanks the loading from the tanks and criteria for adequate factor of safety
against bearing capacity failure and settlement should be discussed.

Commission Staff Guidance

A-25

February 2017

8.1.2 Shallow Foundations
LNG tanks supported on shallow foundations are generally supported on a mat.
Ultimate bearing capacity of the mat should be calculated and should provide a minimum
factor of safety of 3.0 for the applied tank loading during hydrotest. Effects of adjacent
slopes, if present, on the bearing capacity should be evaluated. The reduction of the factor
of safety due to liquefaction or other effects should be evaluated and addressed. Total and
differential settlement of the mat foundation should be calculated under various applied
loads such as during hydrotest, operation, and seismic conditions including liquefaction, if
present.
Recommendations for monitoring of the settlements during hydrotest should be
provided. Lateral stability of the tanks under seismic and wind loads should be calculated
and it should be demonstrated that an adequate factor of safety is present. If lateral
spreading is a seismic issue, lateral stability of the tanks due to lateral spreading movements
should be demonstrated. Overall lateral stability of the foundation for static and seismic
conditions including any adjacent slopes, if present, should be evaluated.
8.1.3 Deep Foundations
For Deep Foundations, the report should address, but not be limited to, the following
when applicable:
1.

Pile Types, Axial Compressive and Tensile, and Settlement
a.

Recommended pile types should be identified as driven Precast
Prestressed Reinforced Concrete piles, Steel H or Pipe piles, cast-in
drilled hole (CIDH) piles, Auger Cast Piles or others. Alternatives
should be discussed and the reasons why those alternatives are not
recommended should be stated.

b.

Whether compressive and/or tensional geotechnical capacities are
derived from skin friction, end bearing, or a combination of both for a
single or group pile(s) should be discussed.

c.

Pile design tip elevations (DTE) may be controlled by demands from
compression, tension, lateral loads, scour potential, or liquefaction.
The pile Specified Tip Elevation (STE) equals the lowest pile DTE as
estimated above.

d.

The portion of the axial capacities for pile foundations in and above
liquefiable soils should be neglected.

e.

Negative skin friction (down-drag) on pile shaft due to settlements of
new fills or compressible soil layers should be eliminated by use of

Commission Staff Guidance

A-26

February 2017

preloading/surcharge with or without wick drains prior to pile
installation or piles should be designed for downdrag associated with
these settlements. Downdrag from settlements due to liquefaction
should also be calculated.

2.

3.

f.

When a situation such as liquefaction potential exists that does not
allow for mitigation and elimination of negative skin friction, the
magnitude of the downdrag forces should be estimated and provided
to the structural designer for him/her to incorporate those forces into
Design Loading. The magnitude of estimated settlement should also be
provided to the structural engineer.

g.

Lateral pile capacity should be estimated using the p-y method or
equivalent. Group reduction factors depending on soil types, pile
spacing, and anticipated lateral movement should be considered when
evaluating lateral capacity for a group of piles. Formulation of p-y
curves for liquefiable soils and weak rocks, effects of pile diameters
on lateral soil modulus and soil strain parameters, evaluation of
liquefaction or lateral spreading forces imposed on pile, and reduced
moment of inertia for concrete piles should be addressed.

h.

The single and/or group pile settlement should not exceed the tolerable
amount as established by the structural designer.

Special Considerations for Cast-In Drilled Hole (CIDH) Piles
a.

When battered piles are required, CIDH piles should not be used
because of the increased risk of caving and the difficulty of placing
concrete in a sloping hole.

b.

If pile tips are below the groundwater table or wet construction
method is used, CIDH piles should be designed at a diameter equal to
or greater than 24 in.

c.

When CIDH piles are used under water, no end bearing should be used
unless positive measures to verify the end bearing are recommended.

Installation of Driven Piles

Pile drivability should be evaluated by wave equation analyses. An indicator pile
program including pile driving analyzer (PDA) measurements should be planned to
verify the pile drivability and the estimated capacity. A load test program should be
developed to verify the capacity of selected piles both under axial and lateral conditions.

Commission Staff Guidance

A-27

February 2017

4.

Installation of Drilled or Auger Cast Piles

Gamma-Gamma testing should be performed on CIDH piles installed
underwater by the wet method to verify the integrity of the piles.
An axial and lateral load test program should be implemented to verify the axial and
lateral capacity of the piles. Pile Load Test can be used for determining pile capacity at
failure (ultimate capacity), and for establishing field acceptance criteria. A load test
remains the definitive way to determine whether the professional's estimate of capacity and
specified tip elevations is appropriate in design and to determine whether the production
piles meet the specifications during construction. The equipment and procedures for
conducting pile axial compressive load tests can be found in literature such as ASTM D
1143. Static axial tension tests should be performed per ASTM D 3689. Static lateral load
tests should be performed per ASTM D 3966.
8.1.4

Ground Improvement

Ground Improvement should discuss the need for ground improvement, type(s) of
ground improvement, surcharge, stone columns, vibroflotation, soil-cement columns,
dynamic compaction, and other types of ground improvement. The discussion should
address the effects of ground improvements on soil properties and seismic ground motions.
9.

Corrosion

An assessment of the corrosiveness of a site based on the review of relevant
corrosion test data should be made. Corrosion test data should include pH, electrical
resistivity, stray electrical ground currents, water soluble sulfates and chlorides. Sufficient
information regarding the number and location of soil borings for corrosion testing should
be included to allow a thorough review of the recommendations. Recommendations
regarding concrete and metals in contact with onsite soils should be provided.
10. Pavement Design
Recommendations for design of asphalt and Portland cement concrete pavements
for the plant area should be provided based on the onsite soil R-value or CBR.
