DISCUSSION:
The City of Seal Beach has received an application for a Conditional Use Permit (CUP 20-
4) for the installation of a new hydrogen fueling facility at an existing gasoline station and
convenience store located at 13980 Seal Beach Boulevard. The existing gasoline fueling
station is located on a .54 acre (23,215 square feet) lot within the General Commercial
zoned area. The proposed hydrogen fueling station would be similar in construction and
appearance to the existing gasoline fueling stations and would provide two new hydrogen
fuel dispensers. The existing convenience store, fueling bays canopy, and associated
gasoline fueling equipment would remain on site, as would the auto service and repair
station attached to the convenience store.
In addition, an approximately 1,010-square-foot hydrogen equipment enclosure would be
constructed in the northern portion of the project site. The enclosure would be a four-sided
wall/fence structure without a roof. The enclosure would be of decorative CMU
construction and include a steel screening fence along with steel doors or gates to restrict
access. Hydrogen equipment in the enclosure would include two hydrogen station
modules for gas compression, hydrogen gas storage vessels, and a delivery manifold for
off-loading fuel deliveries. Underground fuel pipelines would be installed to carry the
hydrogen to two dispenser pumps, which would be installed west of the existing fueling
stations.
The proposed fueling facility is a project that is subject to review under the California
Environmental Quality Act (CEQA) 1970 (Public Resources Code, Section 21000 et seq.)
and the State CEQA Guidelines (California Code of Regulations, Section 15000 et seq.).
An Initial Study has been prepared by a third-party consultant, Rincon Consultants, Inc., to
assess the short-term, long-term, and cumulative environmental impacts that could result
from the proposed gas station and convenience store. The report has been prepared to
comply with Section 15063 of the State CEQA Guidelines, which sets forth the required
contents of an Initial Study. These include:
A description of the project, including the project location.
Identification of the environmental setting.
Identification of environmental effects by use of a checklist, matrix, or other
methods, provided entries on the checklist or other forms are briefly explained to
indicate that there is some evidence to support the entries.
Discussion of ways to mitigate significant effects identified, if any.
Examination of whether the project is compatible with existing zoning, plans, and
other applicable land use controls.
The name(s) of the person(s) who prepared or participated in the preparation of the
Initial Study.
Environmental Quality Control Board
March 24, 2021

Based on the findings of the Initial Study, the City has determined that this project would
not result in significant environmental impacts with the incorporation of mitigation
measures to address potential air quality, cultural resources, geology and soils, hazards
and hazardous materials, noise, and transportation impacts. As described more fully
below, measures to reduce these impacts regarding the fore mentioned areas will be
incorporated into the project conditions of approval. Accordingly, the City intends to adopt
a Mitigated Negative Declaration pursuant to Section 21080(c) of the Public Resources
Code.
A few of the areas that were identified as potentially significant but with proposed
mitigation measures would be less than significant are the areas of cultural resources of
possible Native American Artifacts, and geology and soils preparation.
The cultural resources section identifies the possibility of discovering unanticipated
archaeological resources. The project would involve construction within a fully developed
and previously disturbed site. Construction of the existing gasoline station on the site
required excavation and disturbed native soils, reducing the potential for subsurface
archaeological resources to remain intact on-site. However, there is always the possibility
to encounter intact archaeological deposits or undocumented human remains during
construction. If encountered, construction could damage or destroy these resources or
remains. With implementation of the Mitigation Measure CR-1, the project would have a
less than significant impact on archaeological resources.
If cultural resources are encountered during ground-disturbing activities, work in the
immediate area shall be halted and an archaeologist meeting the Secretary of the
Interior’s Professional Qualification Standards for archaeology (NPS 1983) shall be
contacted immediately to evaluate the find. If necessary, the evaluation may require
preparation of a treatment plan and archaeological testing for CRHR eligibility. If the
discovery proves to be significant under CEQA and cannot be avoided by the project,
additional work such as data recovery excavation may be warranted to mitigate any
significant impacts to cultural resources. In the event that archaeological resources of
Native American origin are identified during project construction, a qualified archaeologist
shall consult with the City of Seal Beach to begin Native American consultation
procedures. As part of this process, it may be determined that archaeological monitoring is
required. A Native American monitor may also be required in addition to the archaeologist.
The geology and soils preparation for the construction of the project shall follow a
geotechnical investigation prepared by the applicant. This report shall be submitted with
the grading plans and all grading shall follow the recommendations of the report.
The project site is relatively flat and would require little to no grading to install the
proposed hydrogen fueling facilities. Excavation would be required but would be
minimal. Most of the site would remain covered in either asphalt or structures during
project construction, and all disturbances would be repaved following construction.
Therefore, the potential for soil erosion or loss would be negligible. Impacts would be
less than significant.
Environmental Quality Control Board
March 24, 2021

In addition, the proposed project would be constructed on existing engineered fill that
was graded and prepared when the existing gasoline station was constructed on the
project site. The proposed project would involve relatively shallow trenching to install
electrical conduit and hydrogen fuel lines. These trenches would be backfilled and
compacted in accordance with the California Building Code. Therefore, the proposed
project would not lead to unstable geology or soils. Impacts would be less than
significant.
The project site has been listed twice for contaminant releases associated with on-site
leaking underground storage tanks (LUSTs). Both cases were related to gasoline
contamination of local groundwater supplies. The first case was closed in December
1991, following the reported release in April 1990 and closure and removal of the leaking
tank. The second case was reported in October 1998 and closed in March 2013, following
replacement of product piping. Monitoring of local wells has confirmed no substantial
pollutant quantities entered the local groundwater as a result of both LUST cases
(SWRCB 2020b, 2020c).
A thirty-day public review period is being held that began Friday February 26, 2021 and
will conclude Monday March 29, 2021. During this period, the IS/MND is available for
public review at the City of Seal Beach website http://www.sealbeachca.gov. At the time of
this report, staff has not received any comments. All comments received regarding this
project during the public review period will be shared with the consultant and included as
part of the Initial study process.

7. Surrounding Land Uses
The project site consists of an existing convenience store and gas station within the Seal Beach
Village commercial shopping. Retail parking for the shopping center is adjacent to the north side of
the project site. The larger commercial anchor stores in the shopping center are along the western
end of the parking area northwest of the project site. The site is bounded by Seal Beach Boulevard
to the east and Westminster Boulevard to the south. A chiropractic clinic is located immediately
west of the project site. Several additional commercial buildings are located south of Westminster
Boulevard and southwest of the project site. A naval weapons station is located southeast and east
of the site. An aerial photograph of the site and its surrounding land uses is shown in Figure 2.
8. Description of Project
The proposed project consists of the installation of a new hydrogen fueling facility at an existing
gasoline station and convenience store. The proposed hydrogen fueling station would be similar in
construction and appearance to the existing gasoline fueling stations and would provide two new
hydrogen fuel dispensers. The existing convenience store, fueling bays canopy, and associated
gasoline fueling equipment would remain on site, as would the auto service and repair station
attached to the convenience store.
An approximately 1,010-square-foot hydrogen equipment enclosure would be constructed in the
northern portion of the project site. The enclosure would be a four-sided wall structure without a
roof. The enclosure would be of metal stud construction with fire code gypsum panel with a stucco
facade and include steel doors or gates to restrict access. Hydrogen equipment in the enclosure
would include two hydrogen station modules for gas compression, hydrogen gas storage vessels,
and a delivery manifold for off-loading fuel deliveries. Underground fuel pipelines would be installed
to carry the hydrogen to two dispenser pumps, which would be installed west of the existing fueling
stations in the southern portion of the site, below the expanded canopy structure. Associated
electrical equipment would be installed adjacent to the exterior of the enclosure.
The proposed project would also involve construction of a new trash enclosure along the western
site boundary, reconfiguration of landscaping areas, relocation of the air-water unit, relocation of
the propane tank, removal of the existing Healy tank, conversion of the existing fueling system into
an enhanced vapor recovery system, removal of one parking space along the northern site
boundary, installation of an ADA parking stall near the proposed enclosure, removal of a concrete
swale, and curb modifications at the existing southwestern-most driveway. The proposed
conceptual site plan is shown in Figure 3.

Project Construction
Construction activities would begin soon after entitlements are granted and would be completed in
approximately 6 to 8 months. Construction activities would include installation of the equipment
enclosure and excavation as part of installation of fuel pumps and related infrastructure. The
maximum excavation depth would be 4.5 feet; however, most of the excavation would be in the 2-
foot to 3-foot range. Soil excavated would be stored onsite during construction and used to backfill
excavation. However, as hydrogen fueling infrastructure would occupy space in the excavation, not
all soil would be reused. Excess soil would be exported from the site.
The project would be constructed within an area that is currently paved with asphalt concrete.
Therefore, the proposed project would not increase the amount of impervious surface on the site.
However, pavement that is damaged or demolished during construction, such as the required
excavation, would be restored.
Project Operation
The proposed hydrogen fueling station would operate from 6:00 a.m. to 10:00 p.m., 7 days a week,
consistent with the operational hours of the existing convenience store and gasoline fueling facilities
on-site. Cars that operate using hydrogen are known as fuel-cell electric vehicles (FCEV). As FCEVs
become more popular and common, the number of daily trips to the hydrogen fueling station could
increase.
Hydrogen gas would be delivered to the site, as needed, based on supply and demand. Tractor
trailer trucks designed to transport liquid and gaseous substances, commonly known as tanker
trucks, would deliver fuel to the site. Initially, delivery would occur approximately once per week.
Delivery frequency could increase as FCEVs become more common and the demand for hydrogen
fuel increases. Maximum delivery frequency, based on maximum possible demand, would be once,
daily.
The proposed hydrogen fueling facilities would not change current operations of the existing
convenience store, gasoline fueling station, and auto service station.
9. Required Public Agency Permits and Approvals
The proposed project would require the following entitlements, permits, and/or approvals:
City of Seal Beach Grading Permit

Determination
Based on this initial evaluation:
□ I find that the proposed project COULD NOT have a significant effect on the environment,
and a NEGATIVE DECLARATION will be prepared.
■ I find that although the proposed project could have a significant effect on the
environment, there will not be a significant effect in this case because revisions to the
project have been made by or agreed to by the project proponent. A MITIGATED
NEGATIVE DECLARATION will be prepared.
□ I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
□ I find that the proposed project MAY have a “potentially significant impact” or “less than
significant with mitigation incorporated” impact on the environment, but at least one
effect (1) has been adequately analyzed in an earlier document pursuant to applicable
legal standards, and (2) has been addressed by mitigation measures based on the earlier
analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is
required, but it must analyze only the effects that remain to be addressed.
□ I find that although the proposed project could have a significant effect on the
environment, because all potential significant effects (a) have been analyzed adequately
in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b)
have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION,
including revisions or mitigation measures that are imposed upon the proposed project,
nothing further is required.

a. Would the project have a substantial adverse effect on a scenic vista?
As documented in the City of Seal Beach General Plan, the coastal waterfront, including shoreline
and marshlands, is one of the City’s most valuable assets. The project site is at least 1.8 miles from
the waterfront scenic area, and 1.0 mile north of the Seal Beach National Wildlife Refuge, which
contains the marshlands and ecological areas. The project site and the surrounding area are
relatively flat. Prominent viewpoints, other than the surrounding buildings, are limited. Views from
the project site are primarily of surrounding urban development, such as the retail shopping center
northwest of the site. The proposed hydrogen fueling facilities would appear similar to the existing
gasoline fueling facilities on the project site and would therefore be consistent with the urban
design conditions of the surrounding shopping center. The proposed hydrogen fueling facilities
would be no taller or prominent than existing facilities on the project site. Therefore, no scenic
views would be obstructed, and impacts would be less than significant.

b. Would the project substantially damage scenic resources, including but not limited to, trees,
rock outcroppings, and historic buildings within a state scenic highway?
There are no state-designated scenic highways in Seal Beach. In Orange County, the only state-
designated scenic highway is State Route (SR) 91 between Route 55 to the Anaheim city limit
(Caltrans 2019). The distance between the designated segment of SR 91 and the project site is over
15 miles, and therefore not within the viewshed of an identified scenic highway.
Eligible State Scenic Highways that are not officially designated include: SR 57 from Route 90 to
Route 60 near the City of Industry, SR 74 from I-5 near San Juan Capistrano to the I-111, and SR 91
from Route 55 near Santa Ana Canyon to I-15 near Corona (Caltrans 2019). The project site is
greater than 15 miles from the nearest of these roadway segments. There would be no impact.
NO IMPACT
c. Would the project, in non-urbanized areas, substantially degrade the existing visual character
or quality of public views of the site and its surroundings? (Public views are those that are
experienced from a publicly accessible vantage point). If the project is in an urbanized area,
would the project conflict with applicable zoning and other regulations governing scenic
quality?
The project site is in an existing fueling station in an urbanized part of Seal Beach. The project would
add hydrogen fueling facilities to the station. The project site is zoned General Commercial, which
allows for the fueling station. The hydrogen fueling facilities would appear like existing gasoline
fueling facilities, such as fuel dispenser machines. Accordingly, the proposed project would not
conflict with applicable zoning and other regulations governing scenic quality. Impacts would be less
than significant.
LESS THAN SIGNIFICANT IMPACT
d. Would the project create a new source of substantial light or glare that would adversely affect
daytime or nighttime views in the area?
The proposed project would include extension of the existing lighted canopy to cover the proposed
hydrogen fuel dispensers, to aid customers in refueling during night. Apart from this extension, no
additional lights would be installed as part of the project. Canopy lighting would be directed
downward toward the dispensers. The lights must also comply with Seal Beach Municipal Code
(SBMC) Section 11.4.05.050(B)(6), which pertains to outdoor canopy lighting. The code requires
outdoor lighting to be energy efficient, stationary, and shielded or recessed to ensure that all light is
directed away from adjoining public rights-of-way and properties. The new canopy lights would be
required to comply with SBMC Section 11.4.05.050(B)(6), ensuring the project would not result in a
substantial source of new light. The proposed project would not involve the use of reflective
materials that create glare. Impacts would be less than significant.

Air Quality Standards and Attainment
The project site is located within the South Coast Air Basin (Basin), which is under the jurisdiction of
the South Coast Air Quality Management District (SCAQMD). As the local air quality management
agency, SCAQMD is required to monitor air pollutant levels to ensure that National Ambient Air
Quality Standards (NAAQS) and California Ambient Air Quality Standards (CAAQS) are met and, if
they are not met, to develop strategies to meet the standards. Depending on whether the standards
are met or exceeded, the Basin is classified as being in “attainment” or “nonattainment.” In areas
designated as non-attainment for one or more air pollutants, a cumulative air quality impact exists
for those air pollutants, and the human health impacts associated with these criteria pollutants,
presented in Table 1, are already occurring in that area as part of the environmental baseline
condition. Under state law, air districts are required to prepare a plan for air quality improvement
for pollutants for which the district is in non-compliance. The Basin is designated a nonattainment
area for the federal standards for ozone and PM2.5 (particulate matter up to 2.5 microns in size) and
the state standards for ozone, PM10 (particulate matter up to 10 microns in size), and PM2.5
(SCAQMD 2016). This nonattainment status is a result of several factors, the primary ones being the
naturally adverse meteorological conditions that limit the dispersion and diffusion of pollutants, the
limited capacity of the local airshed to eliminate air pollutants, and the number, type, and density of
emission sources in the Basin.

Air Quality Management
Because the Basin currently exceeds federal and state ozone, state PM10, and federal and state
PM2.5 standards, SCAQMD is required to implement strategies to reduce pollutant levels to achieve
attainment of the NAAQS and CAAQS. The 2016 AQMP, adopted on March 3, 2017, incorporates
new scientific data and notable regulatory actions that have occurred since adoption of the 2012
AQMP, including the approval of the new federal 8-hour ozone standard of 0.070 ppm that was
finalized in 2015.
The 2016 AQMP addresses several State and federal planning requirements and incorporates new
scientific information, primarily in the form of updated emissions inventories, ambient
measurements, and updated meteorological air quality models (SCAQMD 2017). This Plan builds
upon the approaches taken in the 2012 AQMP for the attainment of federal PM and ozone
standards, and highlights the significant amount of reductions to be achieved. It emphasizes the
need for interagency planning to identify additional strategies to achieve reductions within the
timeframes allowed under the federal Clean Air Act, especially in the area of mobile sources. The
2016 AQMP also includes a discussion of emerging issues and opportunities, such as fugitive toxic
particulate emissions, zero-emission mobile source control strategies, and the interacting dynamics
among climate, energy, and air pollution. The Plan also includes attainment demonstrations of the
new federal 8-hour ozone standard and vehicle miles travelled (VMT) emissions offsets, as per
recent U.S. EPA requirements (SCAQMD 2017).
Air Emission Thresholds
Regional Thresholds
The 2016 AQMP provides a strategy for the attainment of state and federal air quality standards.
The SCAQMD recommends quantitative regional significance thresholds for temporary construction
activities and long-term project operation within the Basin, shown in Table 2.

Localized Significance Thresholds
In addition to regional thresholds, the SCAQMD has developed Localized Significance Thresholds
(LSTs) in response to the Governing Board’s Environmental Justice Enhancement Initiative (1-4),
which was prepared to update the CEQA Air Quality Handbook. LSTs were devised in response to
concern regarding exposure of individuals to criteria pollutants in local communities. LSTs represent
the maximum emissions from a project that will not cause or contribute to an air quality exceedance
of the most stringent applicable federal or state ambient air quality standard at the nearest
sensitive receptor, taking into consideration ambient concentrations in each source receptor area
(SRA), project size, and distance to the sensitive receptor. However, LSTs only apply to emissions
within a fixed stationary location, including idling emissions during both project construction and
operation. LSTs have been developed for NOX, CO, PM10, and PM2.5. LSTs do not apply to mobile
sources such as cars on a roadway (SCAQMD 2008a). As such, LSTs for operational emissions do not
apply to onsite development since the majority of emissions would be generated by cars on the
roadways.
The project site is 0.54 acre in size and is located in Source Receptor Area 18 (SRA 18), North Coastal
Orange County (SCAQMD 2008a). The SCAQMD provides LSTs for one-, two-, and five-acre project
sites for receptors at a distance of 82 to 1,640 feet (25 to 500 meters) from the project site
boundary. Because the project site is less than one acre in size, the LSTs associated with one-acre
sites are used for the construction air quality analysis are provided in Table 3. The project site is
adjacent to commercial land uses; therefore, the 25-meter receptor distance is appropriate.

Methodology
Air pollutant emissions generated by project construction and operation were estimated using the
California Emissions Estimator Model (CalEEMod), version 2016.3.2. CalEEMod uses project-specific
information, including the project’s land uses, square footages for different uses (e.g.,
gasoline/service station for the new hydrogen pumps, parking lot for the new ADA parking space,
and other non-asphalt surfaces for the hydrogen equipment area), and location, to model a
project’s construction and operational emissions. The analysis reflects the construction and
operation of the project as described in Section 2.8, Description of Project.
Construction emissions modeled include emissions generated by construction equipment used on-
site and emissions generated by vehicle trips associated with construction, such as worker and
vendor trips. CalEEMod estimates construction emissions by multiplying the amount of time
equipment is in operation by emission factors. Construction of the proposed project was analyzed
based on the CalEEMod default construction schedule and construction equipment list. It is
assumed that all construction equipment used would be diesel-powered. This analysis assumes that
the project would comply with all applicable regulatory standards. In particular, the project would
comply with SCAQMD Rule 403 (Fugitive Dust).
Operational emissions modeled include mobile source emissions (i.e., vehicle emissions), energy
emissions, and area source emissions. Mobile source emissions are generated by vehicle trips to and
from the project site. The trip generation rate used is consistent with the methodology described in
Section 17, Transportation; based on trip generation information from similarly sized facilities, trips
were estimated for the proposed facility to be approximately 80 daily trips. Emissions attributed to
energy use include the increase in natural gas consumption for water heating at the existing
convenience store, due to the increase in daily customers and associated increase in water usage at
the on-site restroom facilities, although the store would not be expanded. Area source emissions
are generated by landscape maintenance equipment, consumer products and architectural coatings.
a. Would the project conflict with or obstruct implementation of the applicable air quality plan?
A project may be inconsistent with the AQMP if it would generate population, housing, or
employment growth exceeding the forecasts used in the development of the AQMP. The 2016
AQMP relies on local cities’ general plans and the Southern California Association of Government’s
(SCAG) Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) forecasts of
regional population, housing, and employment growth in its own projections for managing Basin air
quality.
Construction of the proposed hydrogen fueling facility would not generate new employment
opportunities that cause relocation to the area given the temporary nature of construction and the
interconnectedness of the southern California region. Project operation would not require increased
employment at the existing gas station. Additionally, hydrogen delivery truck trips would not result
in increased employment, as the project site would be one stop on the overall route that the truck
currently makes to deliver hydrogen fuel in the region. Therefore, the project would not induce
population growth that would conflict with the growth forecasts contained in the 2016 AQMP.
Further, the addition of hydrogen fueling facilities in the project area could expand the use of
hydrogen fuel vehicles, which emit only water (hydrogen and oxygen). Accordingly, impacts would
be less than significant.

b. Would the project result in a cumulatively considerable net increase of any criteria pollutant for
which the project region is non-attainment under an applicable federal or state ambient air
quality standard?
Hydrogen is not a regulated pollutant, so the storage of hydrogen fuel in tanks would not violate an
air quality standard or contribute substantially to an existing or projected air quality violation.
Stations that merely accept hydrogen fuel deliveries would likely not need air permits for hydrogen
fuel storage tanks, as they would have no regulated emissions.
Construction activities associated with development of the proposed project would generate diesel
emissions and dust. Construction emissions modeled include emissions generated by construction
equipment used on-site and emissions generated by vehicle trips associated with construction, such
as worker and vendor trips. It is assumed that all of the construction equipment used would be
diesel-powered. Construction emissions were calculated using the California Emissions Estimator
Model (CalEEMod) version 2016.3.2. CalEEMod was developed for use throughout the state in
estimating construction and operational emissions from land use development. Emissions were
based on parameters such as the duration of construction activity, area of disturbance, and
anticipated equipment use during construction. The construction schedule and equipment list for
the proposed road project were provided by the applicant.
For the purposes of construction emissions modeling, it was assumed that the project would comply
with SCAQMD Rule 403, which identifies measures to reduce fugitive dust and is required to be
implemented at all construction sites located within the Basin. Therefore, the following conditions,
which are required to reduce fugitive dust in compliance with SCAQMD Rule 403, were included in
CalEEMod for the site preparation and grading phases of construction.
1. Minimization of Disturbance. Construction contractors shall minimize the area disturbed by
clearing, grading, earth moving, or excavation operations to prevent excessive amounts of dust.
2. Soil Treatment. Construction contractors shall treat all graded and excavated material, exposed
soil areas, and active portions of the construction site, including unpaved on-site roadways to
minimize fugitive dust. Treatment shall include, but not necessarily be limited to, periodic
watering, application of environmentally safe soil stabilization materials, and/or roll compaction
as appropriate. Watering shall be done as often as necessary, and at least twice daily, preferably
in the late morning and after work is done for the day.
3. No Grading During High Winds. Construction contractors shall stop all clearing, grading, earth
moving, and excavation operations during periods of high winds (20 miles per hour or greater,
as measured continuously over a one-hour period).
4. Street Sweeping. Construction contractors shall sweep all on-site driveways and adjacent
streets and roads at least once per day, preferably at the end of the day, if visible soil material is
carried over to adjacent streets and roads.
As shown in Table 4 and Table 5, estimated maximum daily emissions during construction and
operation of the proposed road project would not exceed SCAQMD regional thresholds or LSTs.
Therefore, project construction and operation would not violate any air quality standard or
contribute substantially to an existing or projected air quality violation, and impacts would be less
than significant.

c. Would the project expose sensitive receptors to substantial pollutant concentrations?
Environmental Checklist
Air Quality
Initial Study – Mitigated Negative Declaration 21
Construction of the proposed project would involve the use of heavy equipment powered by diesel
fuel, such as a backhoe. Diesel exhaust contains various pollutants that can be harmful to the
environment or human health. Construction of the project would be short term and temporary for
approximately 5 to 6 months. The installation of the proposed hydrogen fueling facilities would be
minor construction project, not requiring extensive equipment over extended periods of time.
Because the site is an existing gasoline station, construction equipment would primarily be operated
on asphalt pavement, resulting in little dust emissions. Additionally, as described above, project
construction would result in minor air quality emissions, substantially below SCAQMD thresholds for
all pollutants. Accordingly, construction emissions would not expose sensitive receptors to
substantial pollutant concentrations.
Hydrogen gas would be delivered to the site by tanker trucks during the operational life of the
project. Like construction equipment, tanker trucks also generate diesel exhaust. Delivery would
occur infrequently. Initially, delivery would occur approximately once per week. Delivery frequency
could increase as FCEVs become more common and the demand for hydrogen fuel increases.
Maximum delivery frequency, based on maximum possible demand, would be once, daily. A daily
increase of a single tractor trailer trip on Seal Beach Boulevard or Westminster Boulevard would not
generate substantial pollutant concentrations.
As described above, hydrogen is not a regulated pollutant; therefore, the project is not expected to
expose sensitive receptors to substantial pollutant concentrations. Trips made to the site in order to
refuel would be by FCEV. As electric vehicles, FCEVs generate no pollutant emissions. For the
reasons explained above, impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
d. Would the project result in other emissions (such as those leading to odors) adversely affecting
a substantial number of people?
Hydrogen is an odorless gas. Therefore, the hydrogen fuel would result in no adverse odors.
However, construction and delivery would require use of diesel equipment, such as a backhoe and
tanker truck. Diesel exhaust may be described by some as an adverse odor. However, construction
would be temporary, and delivery of fuel with a tanker truck would be infrequent.
The proposed project includes a new trash enclosure at the western boundary of the site. Some
trash, such as decomposing food material, may generate odors that some people find adverse.
However, the proposed project would not generate new amounts of trash. Therefore, the proposed
trash enclosure would not introduce new odors to the site. Impacts would be less than significant.

The project site is an existing gasoline station that is part of a shopping center in an urbanized
portion of Seal Beach. Landscaping is currently present along the project site’s western boundary, in
the northern portion of the site, and in the southeast corner of the site. These areas contain
landscaped lawn area and ornamental trees. In this area, Seal Beach Boulevard is comprised of eight
travel lanes and Westminster Boulevard has seven travel lanes. Given that vegetation consists of
narrow strips of landscaping near busy roadways and a shopping center, it is unlikely to support
special status species. The landscaping is also regularly maintained by contractors. Furthermore,
while the proposed project would alter or remove some of the is landscaped area, new landscaping
is proposed to replace affected areas. Similarly, riparian habitat or other sensitive natural
community do not occur on-site nor within the landscaped areas. Therefore, the proposed project
would have a less than significant impact on special-status species, riparian habitat, or other
sensitive species or natural communities.

c. Would the project have a substantial adverse effect on state or federally protected wetlands
(including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling,

have no impact.
NO IMPACT
d. Would the project interfere substantially with the movement of any native resident or
migratory fish or wildlife species or with established native resident or migratory wildlife
corridors, or impede the use of native wildlife nursery sites?
There are no streams or other surface waters on or adjacent to the project site. Therefore, the
project site is not used for fish migration or movement. As described above under criteria a) and b),
the vegetation on the project site is limited to landscaped areas surrounding and within the site.
These areas are isolated from contiguous habitat or corridors because it is surrounded by busy
arterial streets and a shopping center. Additionally, the landscaping is regularly maintained with
activities such as mowing and pruning. Therefore, the project site has no value to wildlife movement
or migration, and it is not a native wildlife nursery. The proposed project would have no impact.
NO IMPACT
e. Would the project conflict with any local policies or ordinances protecting biological resources,
such as a tree preservation policy or ordinance?
The landscaped areas within and adjacent to the project site contain ornamental trees. The
proposed project would require the removal of seven existing ornamental juniper trees at the
proposed hydrogen equipment storage area. One tree in the landscaped area near the proposed
trash enclosure could be trimmed during project construction but would not be removed.

pursuant to §15064.5?
To be considered a historical resource as defined in California Code of Regulations (CCR) Section
15064.5, a district, site, building, or structure must be significant for their traditional, cultural,
and/or historical associations. The project site as well as the surrounding shopping center are not
listed on the National Register of Historic Places (National Park Service 2021). The project site is also
not listed on the California Register of Historic Resources, and there are no sites on the California
Register of Historic Resources within 1.5 miles of the project site (California Office of Historic
Preservation 2021). The existing gas station on the project site dates to at least 1963, based on a
review of aerial photography dated 1963. Based on aerial photography, the surround shopping
center was constructed between 1963 and 1972 (Historic Aerials 2021). While the existing gas
station dates to at least 1963, the structure has been updated or remodeled through time. For
example, the gas pumps have been updated with modern electronic pumps, typical of current era
gasoline dispensers. The gasoline station is not associated with historic or traditional events.
The proposed hydrogen fuel facilities would not alter the gas station structure. The proposed
hydrogen fuel dispensers would appear similar to and function like the existing gasoline pumps on
the site. Other components of the project, such as the hydrogen fuel storage area and trash
dumpster enclosure would appear similar to the existing gasoline station structure and
infrastructure. Additionally, the proposed project would not alter the use of the site as a refueling
station and convenience store.
Because the site is not associated with historical or traditional events, and not listed as historic
resources, and because the project would not substantially alter the site, there would be no impact
to historic resources.

b. Would the project cause a substantial adverse change in the significance of an archaeological
resource pursuant to §15064.5?
The project would involve construction within a fully developed and previously disturbed site.
Construction the existing gasoline station on the site required excavation and disturbed native soils,
reducing the potential for subsurface archaeological resources to remain intact on-site. However,
there is always the possibility to encounter intact archaeological deposits or undocumented human
remains during construction. If encountered, construction could damage or destroy these resources
or remains. With implementation of the Mitigation Measure CR-1, the project would have a less
than significant impact on archaeological resources.
Mitigation Measures
CR-1 Discovery of Unanticipated Archaeological Resources
If cultural resources are encountered during ground-disturbing activities, work in the immediate
area shall be halted and an archaeologist meeting the Secretary of the Interior’s Professional
Qualification Standards for archaeology (NPS 1983) shall be contacted immediately to evaluate the
find. If necessary, the evaluation may require preparation of a treatment plan and archaeological
testing for CRHR eligibility. If the discovery proves to be significant under CEQA and cannot be
avoided by the project, additional work such as data recovery excavation may be warranted to
mitigate any significant impacts to cultural resources.
In the event that archaeological resources of Native American origin are identified during project
construction, a qualified archaeologist shall consult with the City of Seal Beach to begin Native
American consultation procedures. As part of this process, it may be determined that archaeological
monitoring is required. A Native American monitor may also be required in addition to the

c. Would the project disturb any human remains, including those interred outside of formal
cemeteries?
The project would involve construction within a fully developed and previously disturbed site.
Construction the existing gasoline station on the site required excavation and disturbed native soils,
reducing the potential for subsurface human remains to remain intact on-site. If any human remains
are found as a result of construction activities, adherence to California Health and Safety Code
Section 7050.5 would be required. Section 7050.5 requires that if human remains are discovered,
the County Coroner shall be notified to make a determination as to whether the remains are of
Native American origin or whether an investigation into the cause of death is required. If the
remains are determined to be Native American, the Coroner will notify the Native American
Heritage Commission (NAHC) immediately. Once the NAHC identifies the most likely descendants,
the descendants will make recommendations regarding proper burial, which will be implemented in
accordance with Section 15064.5(e) of the CEQA Guidelines. Compliance with the California Health
and Safety Code would ensure impacts to human remains are less than significant.

a. Would the project result in a potentially significant environmental impact due to wasteful,
inefficient, or unnecessary consumption of energy resources, during project construction or
operation?
Construction of the proposed project would require the consumption of fuel energy. However, the
project site is nearly flat and would require minimal use of grading equipment for project
construction. Construction would be short-term and would not require substantial quantities of
equipment. Therefore, project construction would not result in wasteful, inefficient, or unnecessary
consumption of energy resources.
Operation of the project would require electricity to power hydrogen fuel dispensers, and other
project components, such as the proposed panels and switchgears. However, the energy required to
power two fuel dispensers and lighting would be negligible. Additionally, the project would facilitate
the use of FCEVs, which utilize less energy to operate than traditional gasoline-powered vehicles.
Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project conflict with or obstruct a state or local plan for renewable energy or energy
efficiency?
Electricity required for operation of the proposed project would be provided by Southern California
Edison (SCE). In 2019, 48 percent of SCE-provided energy came from carbon-free sources, and SCE is
working toward a goal of providing 80 percent carbon-free energy. SCE is the electricity provider for
residents and businesses in the City of Seal Beach, as well as most of Orange County and many other
nearby counties in southern California. SCE is required to mee the Renewable Portfolio Standards
goal for 2030 to provide at least 60 percent clean energy to its customers. Therefore, energy used
for operation of the project would be consistent with statewide goals.
The City of Seal Beach’s General Plan includes energy conservation opportunities and techniques,
aimed at reducing building energy use (City of Seal Beach 2003). The project would install no
habitable structures; therefore, these strategies would not apply to the project.

Additionally, the provision of hydrogen fueling facilities would facilitate the use of FCEVs, potentially

a.1. Would the project directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving rupture of a known earthquake fault, as delineated on the
most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the
area or based on other substantial evidence of a known fault?
a.2. Would the project directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving strong seismic ground shaking?
The Los Angeles Basin is one of the most seismically active regions in the United States. The
Newport-Inglewood Fault traverses the City of Seal Beach, approximately 1.0 mile southwest of the
project site. The project site would experience intense ground shaking in the event of a large
earthquake. No active faults or fault zones have been mapped on-site (California Department of
Conservation 2020). Therefore, the risk of fault rupture at the project site is low.
The greatest risk during strong seismic ground shaking is structural collapse, leading to falling
objects, such as roofing rafters or retaining walls. The proposed project would not involve the
construction of new building with occupancy or retaining walls. Hydrogen fueling facilities would
largely be at ground level to several feet above ground level and not present a toppling risk during
shaking. Additionally, the project would be constructed consistent with the most current California
Building Code, which requires seismic stability measures be incorporated into design and
construction. For these reasons, impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
a.3. Would the project directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving seismic-related ground failure, including liquefaction?
Liquefaction generally occurs as a result of strong ground shaking in areas where granular sediment
or fill material either contains, or is located immediately above, high moisture content. The ground
shaking transforms the material from a solid state to a temporarily liquid state and can result in
settlement, flow failure, and lateral spreading. Liquefaction is a serious hazard because buildings in
areas that experience liquefaction may sink or suffer major structural damage. These geological and
groundwater conditions are prevalent in the City of Seal Beach and surrounding areas. The project
site is in a liquefaction zone (California Department of Conservation 2020). However, the site is
developed with an existing gas station, which required proper soil compaction and grading when the
station was constructed consistent with mandatory regulations and requirements, such as the
California Building Code. The proposed project would also be constructed consistent with all
regulations pertaining to safety and stability, such as the most current version of the California
Building Code, which addresses seismic safety. With adherence to building regulations, impacts to
people or structures resulting from seismic-related ground failure and liquefaction would be less
than significant.
LESS THAN SIGNIFICANT IMPACT
a.4. Would the project directly or indirectly cause potential substantial adverse effects, including the
risk of loss, injury, or death involving landslides?
Landslides are the downward and outward movements of slope-forming materials including rock,
soil, artificial fill, or combinations of such materials under the direct influence of gravity. The
proposed project site is nearly level, and there are no hills adjacent to the site. There are no known
landslides near the site, nor is the site in an identified landslide zone (California Department of
Conservation 2020). The proposed project does not involve substantial mounding of earth or other

substantive changes to grade that would create slope instability hazards. Therefore, the proposed
project would have no impact.
NO IMPACT
b. Would the project result in substantial soil erosion or the loss of topsoil?
The project site is relatively flat and would require little to no grading to install the proposed
hydrogen fueling facilities. Excavation would be required but would be minimal. Most of the site
would remain covered in either asphalt or structures during project construction, and all
disturbance would be repaved following construction. Therefore, the potential for soil erosion or
loss would be negligible. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
c. Would the project be located on a geologic unit or soil that is unstable, or that would become
unstable as a result of the project, and potentially result in on- or off-site landslide, lateral
spreading, subsidence, liquefaction, or collapse?
The proposed project would be constructed on existing engineered fill that was graded and
prepared when the existing gasoline station was constructed on the project site. The proposed
project would involve relatively shallow trenching to install electrical conduit and hydrogen fuel
lines. These trenches would be backfilled and compacted in accordance with the California Building
Code. Therefore, the proposed project would not lead to unstable geology or soils. Impacts would
be less than significant.
LESS THAN SIGNIFICANT IMPACT
d. Would the project be located on expansive soil, as defined in Table 1-B of the Uniform Building
Code (1994), creating substantial direct or indirect risks to life or property?
Expansive soils have a potential to undergo significant changes in volume in the form of either
shrinking or swelling due to changes in moisture content. Periodic shrinking and swelling of
expansive soils can cause extensive damage to buildings, other structures, and roads. The Uniform
Building Code requirements (defined in UBC Table 18-1-B) were primarily designed to test stability
of foundations to avoid substantial risks to life or property. The proposed project would not require
a building foundation; furthermore, on-site drainage features and compliance with existing building
code requirements would ensure that surface flows do not impact underlying subgrade support
characteristics. Additionally, the entire project site part of a larger shopping center. The site
underwent grading and preparation when the existing fueling facility was constructed to ensure
proper soil compaction and stability. Soils on the project site are engineered fill and are not
expansive soils. For these reasons, impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
e. Would the project have soils incapable of adequately supporting the use of septic tanks or
alternative wastewater disposal systems where sewers are not available for the disposal of
wastewater?
The proposed project involves installation and subsequent operation of hydrogen fueling facilities.
The proposed project would not require the septic tanks or alternative wastewater disposal
systems. The project site is currently served by the City’s sanitary sewer system. The proposed
project would have no impact.

f. Would the project directly or indirectly destroy a unique paleontological resource or site or

The project would involve construction within a fully developed and previously disturbed site.
Construction of the existing gasoline station on the site required excavation and disturbed native
soils, reducing the potential for subsurface paleontological resources to remain intact on-site.
According to the Orange County General Plan, the City of Seal Beach is not within an area of
paleontological sensitivity (County of Orange 2005). However, the project would involve subsurface
construction activities, and there is always possibility for intact paleontological deposits to be
discovered during construction. Impacts would be less than significant with incorporation of
Mitigation Measure GEO-1.

Overview of Climate Change and Greenhouse Gases
Climate change is the observed increase in the average temperature of the Earth’s atmosphere and
oceans along with other substantial changes in climate (such as wind patterns, precipitation, and
storms) over an extended period of time. Climate change is the result of numerous, cumulative
sources of GHG emissions contributing to the “greenhouse effect,” a natural occurrence which takes
place in Earth’s atmosphere and helps regulate the temperature of the planet. The majority of
radiation from the sun hits Earth’s surface and warms it. The surface, in turn, radiates heat back
towards the atmosphere in the form of infrared radiation. Gases and clouds in the atmosphere trap
and prevent some of this heat from escaping into space and re-radiate it in all directions.
GHG emissions occur both naturally and as a result of human activities, such as fossil fuel burning,
decomposition of landfill wastes, raising livestock, deforestation, and some agricultural practices.
GHGs produced by human activities include carbon dioxide (CO2), methane, nitrous oxide,
hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. Different types of GHGs have
varying global warming potentials (GWP). The GWP of a GHG is the potential of a gas or aerosol to
trap heat in the atmosphere over a specified timescale (generally, 100 years). Because GHGs absorb
different amounts of heat, a common reference gas (CO2) is used to relate the amount of heat
absorbed to the amount of the gas emitted, referred to as “carbon dioxide equivalent” (CO2e),
which is the amount of GHG emitted multiplied by its GWP. Carbon dioxide has a 100-year GWP of
one. By contrast, methane has a GWP of 28, meaning its global warming effect is 28 times greater
than CO2 on a molecule per molecule basis (IPCC 2014).1
Anthropogenic activities since the beginning of the industrial revolution (approximately 250 years
ago) are adding to the natural greenhouse effect by increasing the concentration of GHGs in the
atmosphere that trap heat. Since the late 1700s, estimated concentrations of CO2, methane, and
nitrous oxide in the atmosphere have increased by over 43 percent, 156 percent, and 17 percent,
1 The IPCC’s (2014) Fifth Assessment Report determined that methane has a GWP of 28. However, the 2017 Climate Change Scoping Plan
published by the California Air Resources Board uses a GWP of 25 for methane, consistent with the IPCC’s (2007) Fourth Assessment
Report. Therefore, this analysis utilizes a GWP of 25.

respectively, primarily due to human activity (United States Environmental Protection Agency 2020).
Emissions resulting from human activities are thereby contributing to an average increase in Earth’s
temperature. Potential climate change impacts in California may include loss of snow pack, sea level
rise, more extreme heat days per year, more high ozone days, more large forest fires, and more
drought years (State of California 2018).
Regulatory Framework
In response to climate change, California implemented Assembly Bill (AB) 32, the “California Global
Warming Solutions Act of 2006.” AB 32 required the reduction of statewide GHG emissions to 1990
emissions levels (essentially a 15 percent reduction below 2005 emission levels) by 2020 and the
adoption of rules and regulations to achieve the maximum technologically feasible and cost-
effective GHG emissions reductions. On September 8, 2016, the Governor signed Senate Bill 32 into
law, extending AB 32 by requiring the State to further reduce GHG emissions to 40 percent below
1990 levels by 2030 (the other provisions of AB 32 remain unchanged). On December 14, 2017, the
California Air Resources Board (CARB) adopted the 2017 Scoping Plan, which provides a framework
for achieving the 2030 target. The 2017 Scoping Plan relies on the continuation and expansion of
existing policies and regulations, such as the Cap-and-Trade Program and the Low Carbon Fuel
Standard, and implementation of recently adopted policies and legislation, such as SB 1383 (aimed
at reducing short-lived climate pollutants including methane, hydrofluorocarbon gases, and
anthropogenic black carbon) and SB 100 (discussed further below) . The 2017 Scoping Plan also puts
an increased emphasis on innovation, adoption of existing technology, and strategic investment to
support its strategies. As with the 2013 Scoping Plan Update, the 2017 Scoping Plan does not
provide project-level thresholds for land use development. Instead, it recommends local
governments adopt policies and locally-appropriate quantitative thresholds consistent with a
statewide per capita goal of six metric tons (MT) of carbon dioxide equivalents (CO2e) by 2030 and
two MT of CO2e by 2050 (CARB 2017).
Other relevant state laws and regulations include:
SB 375: The Sustainable Communities and Climate Protection Act of 2008 (SB 375), signed in
August 2008, enhances the state’s ability to reach AB 32 goals by directing the CARB to develop
regional GHG emission reduction targets to be achieved from passenger vehicles by 2020 and
2035. Metropolitan Planning Organizations are required to adopt a Sustainable Communities
Strategy (SCS), which allocates land uses in the Metropolitan Planning Organization’s Regional
Transportation Plan (RTP). On March 22, 2018, CARB adopted updated regional targets for
reducing GHG emissions from 2005 levels by 2020 and 2035. The Southern California
Association of Governments (SCAG) was assigned targets of a 8 percent reduction in per capita
GHG emissions from passenger vehicles from 2005 levels by 2020 and a 19 percent reduction in
per capita GHG emissions from passenger vehicles from 2005 levels by 2035. SCAG adopted the
2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (SCAG RTP/SCS) in
September 2020, which meets the requirements of SB 375.
SB 100: Adopted on September 10, 2018, SB 100 supports the reduction of GHG emissions from
the electricity sector by accelerating the state’s Renewables Portfolio Standard Program. SB 100
requires electricity providers to increase procurement from eligible renewable energy resources
to 33 percent of total retail sales by 2020, 60 percent by 2030, and 100 percent by 2045.
California Building Standards Code (California Code of Regulations Title 24): The California
Building Standards Code consists of a compilation of several distinct standards and codes
related to building construction including plumbing, electrical, interior acoustics, energy

efficiency, and handicap accessibility for persons with physical and sensory disabilities. The
current iteration is the 2019 Title 24 standards. Part 6 is the Building Energy Efficiency
Standards, which establishes energy-efficiency standards for residential and non-residential
buildings in order to reduce California’s energy demand. Part 12 is the California Green Building
Standards Code (CALGreen), which includes mandatory minimum environmental performance
standards for all ground-up new construction of residential and non-residential structures.
Methodology
GHG emissions associated with project construction and operation were estimated using CalEEMod,
version 2016.3.2, with the assumptions described under Section 3, Air Quality, in addition to the
following:
Amortization of Construction Emissions. In accordance with South Coast Air Quality
Management District’s (SCAQMD) recommendation, GHG emissions from construction of the
proposed project were amortized over a 30-year period and added to annual operational
emissions to determine the project’s total annual GHG emissions (SCAQMD 2008).
Utility Energy Intensity Factors. Electricity emissions are calculated by multiplying the energy
use times the carbon intensity of the utility district per kilowatt hour (CAPCOA 2017). The
project would be served by Southern California Edison (SCE). Therefore, SCE’s specific energy
intensity factors (i.e., the amount of CO2, CH4, and N2O per kilowatt-hour) are used in the
calculations of GHG emissions. The energy intensity factors included in CalEEMod are based on
2012 data by default at which time SCE had only achieved a 20.6 percent procurement of
renewable energy. Per SB 100, the statewide Renewable Portfolio Standard (RPS) Program
requires electricity providers to increase procurement from eligible renewable energy sources
to 60 percent by 2030. To account for the continuing effects of the RPS, the energy intensity
factors included in CalEEMod were reduced based on the percentage of renewables reported by
SCE. SCE energy intensity factors that include this reduction are shown in Table 6.

2 RPS goal established by SB 100
lbs = pounds; MWh = megawatt-hour; RPS = Renewable Portfolio Standards; SB = Senate Bill
Nitrous Oxide Emissions from Mobile Sources. Because CalEEMod does not calculate nitrous
oxide emissions from mobile sources, nitrous oxide emissions were quantified using guidance
from the CARB and the EMFAC2017 Emissions Inventory for the SCAQMD region for the year
2030 (the next State milestone target year for GHG emission reductions) using the EMFAC2011
categories (CARB 2018 and 2020; see Appendix A for calculations).
Water Use. CalEEMod does not incorporate water use reductions achieved by 2016 CALGreen
(Part 11 of Title 24). New development would be subject to CalGreen, which requires a 20
percent increase in indoor water use efficiency. Thus, in order to account for compliance with
City of Seal Beach
13980 Seal Beach Boulevard Hydrogen Fueling Facility Project
38
CalGreen, a 20 percent reduction in indoor water use was included in the water consumption
calculations for new development.
Significance Thresholds
Individual projects do not generate sufficient GHG emissions to influence climate change directly.
However, physical changes caused by a project can contribute incrementally to significant
cumulative effects, even if individual changes resulting from a project are limited. The issue of
climate change typically involves an analysis of whether a project’s contribution towards an impact
would be cumulatively considerable. “Cumulatively considerable” means the incremental effects of
an individual project are significant when viewed in connection with the effects of past projects,
other current projects, and probable future projects (CEQA Guidelines Section 15064[h][1]).
According to CEQA Guidelines Section 15183.5(b), projects can tier from a qualified GHG reduction
plan, which allows for project-level evaluation of GHG emissions through the comparison of the
project’s consistency with the GHG reduction policies included in a qualified GHG reduction plan.
This approach is considered by the Association of Environmental Professionals (2016) in its white
paper, Beyond Newhall and 2020, to be the most defensible approach presently available under
CEQA to determine the significance of a project’s GHG emissions. The City of Seal Beach does not
have a qualified CAP that can be used for tiering from.
There are no established City thresholds applicable to the project to determine the quantity of GHG
emissions that may have a significant effect on the environment. CARB, the SCAQMD, and various
cities and agencies have proposed, or adopted on an interim basis, thresholds of significance that
require the implementation of GHG emission reduction measures. For the proposed project, which
is located in the South Coast Air Basin, the most appropriate screening threshold for determining
GHG emissions is the SCAQMD proposed Tier 3 screening threshold, which applies to
commercial/residential projects (SCAQMD 2008b); therefore, for the purposes of this analysis, a
significant impact would occur if the proposed project would exceed the SCAQMD proposed Tier 3
screening threshold of 3,000 MT CO2e per year.
a. Would the project generate GHG emissions, either directly or indirectly, that may have a
significant impact on the environment?
Construction and operation of the proposed project would generate GHG emissions. This analysis
considers the combined impact of GHG emissions from both construction and operation.
Calculations of CO2, methane, and nitrous oxide emissions are provided to identify the magnitude of
potential project effects.
Construction of the proposed project would generate temporary GHG emissions primarily as a result
of operation of construction equipment on-site as well as from vehicles transporting construction
workers to and from the project site and heavy trucks to transport building materials and soil
export. As shown in Table 7, construction of the proposed project would generate an estimated
total of 67 MT of CO2e. Amortized over a 30-year period per SCAQMD guidance, construction of the
proposed project would generate an estimated 2 MT of CO2e per year.

Operation of the proposed project would generate GHG emissions associated with area sources
(e.g., landscape maintenance), energy and water usage, vehicle trips, and wastewater and solid
waste generation. As shown in Table 8, annual operational emissions generated by the proposed
project combined with amortized construction emissions would total approximately 29 MT of CO2e
per year, which would not exceed the screening threshold of 3,000 MT of CO2e per year. Therefore,
impacts would be less than significant.

b. Would the project conflict with an applicable plan, policy, or regulation adopted for the purpose
of reducing the emissions of greenhouse gases?
Several plans and policies have been adopted to reduce GHG emissions in the southern California
region, including the State’s 2017 Scoping Plan, and SCAG’s 2020-2045 RTP/SCS. The proposed
City of Seal Beach
13980 Seal Beach Boulevard Hydrogen Fueling Facility Project
40
project’s consistency with these plans is discussed in the following subsections. As discussed
therein, the proposed project would not conflict with plans and policies aimed at reducing GHG
emissions.
2017 Scoping Plan
The principal state plans and policies are AB 32, the California Global Warming Solutions Act of
2006, and the subsequent legislation, SB 32. The quantitative goal of AB 32 is to reduce GHG
emissions to 1990 levels by 2020 and the goal of SB 32 is to reduce GHG emissions to 40 percent
below 1990 levels by 2030. Pursuant to the SB 32 goal, the 2017 Scoping Plan was created to outline
goals and measures for the state to achieve the reductions. The 2017 Scoping Plan’s strategies that
are applicable to the proposed project include reducing fossil fuel use, energy demand, and vehicle
miles traveled (VMT); maximizing recycling and diversion from landfills; and increasing water
conservation. The project would be consistent with these goals through project design, which
includes complying with the latest Title 24 Green Building Code and Building Efficiency Energy
Standards and installing hydrogen fueling infrastructure, which supports the use of alternative fuel
vehicles. The project would be served by Southern California Edison, which is required to increase its
renewable energy procurement in accordance with SB 100 targets. Furthermore, the project would
be required to comply with the City’s recycling requirements for commercial land uses set forth in
SBMC Chapter 6.20, Solid Waste and Recyclables, which would maximize the project’s recycling and
solid waste diversion. Therefore, the project would be consistent with the 2017 Scoping Plan, and
impacts would be less than significant.
SCAG 2020-2045 RTP/SCS
The SCAG 2020-2045 RTP/SCS contains 10 main goals, which include improving mobility and
accessibility, increasing travel choices, reducing GHG emissions and improving air quality, adapting
to a changing climate, and leveraging new transportation technologies. The project would construct
a hydrogen fueling facility on an existing gas station property, which would allow consumers better
access to hydrogen fuels, encouraging the use of hydrogen-fuel vehicles. This would reduce GHG
emissions through the replacement of gasoline vehicles with hydrogen vehicles and support the use
of alternative fueling technologies in the vicinity of the project site. The project would be consistent
with the goals of the RTP/SCS, and impacts would be less than significant.

Regulatory Framework
The storage, use, generation, transport, and disposal of hazardous materials and waste are
regulated under federal and state laws. Federal regulations and policies related to development
include the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA),
commonly known as Superfund, and the Resource Conservation and Recovery Act (RCRA). In
California, the USEPA has granted most enforcement authority over federal hazardous materials
regulations to the California Environmental Protection Agency (CalEPA). In turn, local agencies have
been granted responsibility for implementation and enforcement of many hazardous materials
regulations under the Certified Unified Program Agency (CUPA) program.
Comprehensive Environmental Response, Compensation, and Liability Act
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly
known as Superfund, was enacted by Congress in 1980 and is administered by the USEPA. This law
created a tax on the chemical and petroleum industries and provided broad federal authority to
respond directly to releases or threatened releases of hazardous substances that may endanger
public health or the environment. CERCLA established prohibitions and requirements concerning
closed and abandoned hazardous waste sites, provided for liability of persons responsible for
releases of hazardous waste at these sites, and established a trust fund to provide for cleanup when
no responsible party could be identified.
Resource Conservation and Recovery Act
The Resource Conservation and Recovery Act (RCRA) is a federal law passed by Congress in 1976 to
address the increasing problems from the nation’s growing volume of municipal and industrial
waste. RCRA creates the framework for the proper management of hazardous and non-hazardous
solid waste and is administered by the USEPA. RCRA protects communities and resource
conservation by enabling the USEPA to develop regulations, guidance, and policies that ensure the
safe management and cleanup of solid and hazardous waste, and programs that encourage source
reduction and beneficial reuse. The term RCRA is often used interchangeably to refer to the law,
regulations, and USEPA policy and guidance.
Cortese List
Section 65962.5 of the Government Code requires CalEPA to develop and update a list of hazardous
waste and substances sites, known as the Cortese List. Government Code § 65962.5 was originally
enacted in 1985, and per subsection (g), the effective date of the changes called for under the
amendments to this section was January 1, 1992. While Government Code Section 65962.5 refers to
the preparation of a “list,” many changes have occurred related to web-based information access
since 1992 and this information is now available on the websites of the responsible organizations.
Two of which are the California Department of Toxic Substances Control (DTSC) and the State Water
Resources Control Board (SWRCB), which are responsible for updating the EnviroStor and
GeoTracker databases, respectively (DTSC 2020; SWRCB 2020a). Information in these databases is
considered part of the Cortese List. Refer to the description of these organizations in the state
regulation section below for more information. The Cortese List is used by state and local agencies
and developers to comply with CEQA requirements.

Hazards and Hazardous Materials
Initial Study – Mitigated Negative Declaration 43
California Department of Toxic Substances Control
The California Department of Toxic Substances Control (DTSC) is a State agency that protects State
citizens and the environment from exposure to hazardous wastes by enforcing hazardous waste
laws and regulations. DTSC enforces action against violators; oversees cleanup of hazardous wastes
on contaminated properties; makes decisions on permit applications from companies that want to
store, treat or dispose of hazardous waste; and protects consumers against toxic ingredients in
everyday products. DTSC is responsible for publishing and revising hazardous substance release sites
selected for, and subject to, a response action for inclusion in the EnviroStor database, which is
considered part of the Cortese List described above.
State Water Resources Control Board
The SWRCB is responsible for compiling and updating all underground storage tanks for which an
unauthorized release report is filed. These are referred to as Leaking Underground Storage Tanks
(LUST). The Health and Safety Code Division 20, Chapters 6.7 and 6.75, gives local agencies the
authority to oversee investigation and cleanup of LUST sites. The Santa Ana Regional Water Quality
Control Board (RWQCB) is one of nine regional boards of the SWRCB and is the lead agency
responsible for identifying, monitoring and remediating LUST’s in the Santa Ana region and for
updating the GeoTracker database, which is considered part of the Cortese List described above.
California Department of Industrial Relations, Division of Occupational Safety and
Health
Worker health and safety and public safety are key issues when dealing with hazardous materials.
Proper handling and disposal of hazardous material is vital if it is disturbed during project
construction. The California Department of Industrial Relations, Division of Occupational Safety and
Health (Cal/OSHA) enforces state worker health and safety regulations related to construction
activities. Regulations include exposure limits, requirements for protective clothing, and training
requirements to prevent exposure to hazardous materials. Cal/OSHA also enforces occupational
health and safety regulations specific to lead and asbestos investigations and abatement.
California Accidental Release Prevention Program
The California Accidental Release Prevention (CalARP) Program aims to prevent accidental releases
of regulated substances that can cause serious harm to the public and the environment, to minimize
the damage if releases do occur, and to satisfy community right-to-know laws. Facilities that are
required to participate in the CalARP program use or store more than a threshold quantify of toxic
and flammable substances (hazardous materials) must develop a Risk Management Plan (RMP). An
RMP is a detailed engineering analysis of the potential accident factors present at a business and the
mitigation measures that can be implemented to reduce the potential of accidents occurring. The
County of Orange Environmental Health Division reviews CalARP RMPs as the CUPA.
Asbestos-Containing Materials and Lead-Based Paint
Friable asbestos is any asbestos containing material (ACM) that, when dry, can easily be crumbled or
pulverized to a powder by hand, allowing the asbestos particles to become airborne. Common
examples of products that have been found to contain friable asbestos include acoustical ceilings,
plaster, wallboard, and thermal insulation for water heaters and pipes. Common examples of
nonfriable ACMs are asphalt roofing shingles, vinyl floor tiles, and transite siding made with cement.
The EPA phased out use of friable asbestos products between 1973 and 1978. National Emission

Standards for Hazardous Air Pollutants (NESHAP) guidelines require that potentially friable ACMs be
removed prior to building demolition or remodeling that may disturb the ACMs.
The U.S. Consumer Product Safety Commission banned the use of lead-based paint in 1978.
Removal of older structures with lead-based paint is subject to requirements outlined by Cal/OSHA
Lead in Construction Standard, Title 8, California Code of Regulations 1532.1 during demolition
activities. Requirements include employee training, employee air monitoring, and dust control. If
lead-based paint is peeling, flaking, or blistered, it is required to be removed prior to demolition.
SCAQMD Rules
The SCAQMD regulates the demolition and renovation of buildings and structures that may contain
asbestos, and the manufacture of materials known to contain asbestos. SCAQMD Rule 1403 governs
work practice requirements for asbestos in all renovation and demolition activities. The rule
includes requirements for asbestos surveying, notifications, ACM removal procedures and time
schedules, ACM handling and clean-up procedures, and the storage, disposal, and landfilling
requirements for resulting waste materials. All operators are also required to maintain records,
including waste shipment records, and must use appropriate warning labels, signs, and markings.
City of Seal Beach General Plan
The General Plan includes the following hazards and hazardous materials policies applicable to the
proposed project.
Policy 2B Implement the measures outlined in the City’s Household Hazardous Waste Plan,
Orange County’s Hazardous Waste Management Plan and hazardous Materials Area
Plan, and the County’s Operational Area Marine Oil Spill Contingency Plan to ensure
the effective management, transportation and disposal of hazardous waste on a
City-wide level.
Policy 2F Facilitate coordinated, effective response to hazardous materials emergencies in
the City to minimize health and environmental risks.
Policy 2O Facilitate coordination and participation by all of the jurisdictions that make up the
Los Angeles and Santa Ana Regional Water Quality Control Boards to improve water
quality. Encourage the elimination of sewer discharges and non-point source
pollution into the San Gabriel River.
Policy 2S Minimize changes in hydrology and pollutant loading, require incorporation of
control, including structural and non-structural BMPs to mitigate the projected
increases in pollutant loads and flows, ensure that post-development runoff rates
and velocities from a site have no significant adverse impact on downstream
erosion and stream habitat, minimize the quantity of storm water directed to
impermeable surfaces and the MS4s, and maximize the percentage of permeable
surfaces to allow more percolation of storm water into the ground.
Policy 2V Provide for appropriate permanent measures to reduce storm water pollutant loads
in storm water from the development site.
Existing Conditions
The project site is currently developed with a convenience store, auto service station, and gasoline
station. Due to the existing uses, gasoline fuel is the primary hazardous material currently stored

Hazards and Hazardous Materials
Initial Study – Mitigated Negative Declaration 45
and used on the project site. Gasoline is delivered to the site by tanker truck and stored in
underground tanks connected to fuel dispensers. The gasoline station includes mandatory safety
measures, such as emergency shut-off switches for the fuel dispensers. In addition to gasoline,
hazardous substances may be used in the auto service station, such as motor oils. Additionally,
minor quantities of cleaning fluids and products are stored and used in the convenience store.
The project site has been listed twice for contaminant releases associated with on-site leaking
underground storage tanks (LUSTs). Both cases were related to gasoline contamination of local
groundwater supplies. The first case was closed in December 1991, following the reported release in
April 1990 and closure and removal of the leaking tank. The second case was reported in October
1998 and closed in March 2013, following replacement of product piping. Monitoring of local wells
has confirmed no substantial pollutant quantities entered the local groundwater as a result of both
LUST cases (SWRCB 2020b, 2020c).
a. Would the project create a significant hazard to the public or the environment through the
routine transport, use, or disposal of hazardous materials?
The routine transport, use, and disposal of hazardous materials is a normal part of the existing
operation and maintenance of the gasoline station. As a gasoline station in daily operation, the
project site regularly receives deliveries of fuel. Delivery complies with all applicable federal, state,
and local laws and regulations designed to protect the public from both health risks and
environmental hazards.
The proposed project would result in a slight increase in the routine transport associated with
hydrogen deliveries, and may require minor quantities of lubricants, paints, solvents, and other
products to maintain the hydrogen fueling equipment and enclosures. However, the hydrogen fuel
deliveries would be infrequent and based on market demand, which is expected to be low at first
and slowly increase. Additional materials would be like those currently kept and managed on site for
existing maintenance and operations. The proposed project would therefore have a minimal and
incremental impact on the routine transport, use, and disposal of hazardous materials. The gas
station would continue to comply with all applicable federal, state, and local laws and regulations.
For these reasons, the impact of the project on public hazards resulting from transport, use, or
disposal of hazardous materials would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project create a significant hazard to the public or the environment through
reasonably foreseeable upset and accident conditions involving the release of hazardous
materials into the environment?
Reasonably foreseeable upset and accident conditions involving the release of hazardous materials
to the environment would consist of the potential for hydrogen equipment to leak, rupture or
malfunction, leading to the risk of fire or explosion. Hydrogen is a colorless, odorless, tasteless,
highly flammable diatomic gas with the molecular formula H2. The vapors are lighter than air, and it
is flammable over a wide range of vapor/air concentrations. Hydrogen is not toxic but can be an
asphyxiation risk by displacing oxygen in the air. Hazardous events associated with hydrogen gas
releases would include jet fires, flash fires, and vapor cloud explosions.
The proposed hydrogen fueling system design is required to conform with the National Fire
Protection Association (NFPA) 2 – Hydrogen Technologies Code (2020). The purpose of NFPA 2 is to
provide fundamental safeguards for the generation, installation, storage, piping, use, and handling
City of Seal Beach
13980 Seal Beach Boulevard Hydrogen Fueling Facility Project
46
of hydrogen in compressed gas (GH2) form or cryogenic liquid (LH2) form. One of the requirements
of NFPA 2 is that radiant impacts greater than 1,500 British thermal units per hour per square foot
(Btu/hr· 2) are not allowed off site. It is this requirement that necessitates the installation of solid
barrier walls designed to prevent flame or explosion hazards around the hydrogen equipment
enclosure area, if they were to occur, from extending off site. The NFPA 2 also provides setback
standards to prevent hydrogen hazards from affecting adjacent uses or groups. The proposed
project has been designed to achieve these standards, and fire hazard exposure would not extend
beyond on-site setback areas. The design, installation and testing of the hydrogen fueling station in
accordance with NFPA 2, applicable safety regulations, and professional engineering standards of
care means that the risk of fire or explosion from hydrogen equipment would be low.
Furthermore, the proposed project would include safety precautions to prevent such accidents from
occurring in the first place and to minimize the consequence of such an accident. Accident
prevention measures included in project plans consist of the installation of guard posts to protect
appurtenant facilities from being struck by vehicles and provision of adequate ventilation systems
and pressure release valves. The hydrogen fueling facilities would also include hydrogen-specific
flame detectors and gas detectors, and emergency shutoff switches, designed to stop the flow or
release of hydrogen gas if ignited.
The storage and use of hydrogen gas on-site would not be a substantial increase in hazardous risk
compared with existing uses on-site associated with gasoline and diesel fuel. Gasoline and diesel
fuel, if spilled or leaked, would pool on the ground surface at the project site. The pools would be an
ignition hazard, which could also migrate across the ground surface, spreading the fire. Hydrogen
gas is lighter than air and evaporates instantly and does not pool on the ground. Additionally, the
proposed hydrogen fuel system would have more modern safety features, such as the
aforementioned flame detectors, compared with the existing gasoline and diesel fuel system, which
has existed on-site for decades.
According to the project plans, construction of the proposed project would not involve relocating or
encountering existing buried pipes. Therefore, there would be no potential to encounter pipes with
asbestos containing materials during construction. There would also be no potential to rupture
pipes that are associated with the gasoline station on-site.
Given that the risk of accident and upset conditions associated with the proposed project would be
low, and not more severe than that associated with the existing site, and that the project would
implement numerous safety, accident prevention, and response measures, the risk of exposure to
hazardous materials from accident conditions associated with operation of the project would be
low. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
c. Would the project emit hazardous emissions or handle hazardous or acutely hazardous
materials, substances, or waste within 0.25 mile of an existing or proposed school?
The nearest school to the project site is the JH McGaugh Elementary School, located 1.4 miles
southwest of the site. There are no schools within 0.25 mile of the project site. The proposed
project would not present substantial hazards to schools. No impacts would occur.
NO IMPACT

d. Would the project be located on a site that is included on a list of hazardous material sites
compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a
significant hazard to the public or the environment?
As described above in Existing Conditions, the project site currently appears on the Cortese list due
to groundwater contamination associated with closed LUST cases. Because these two cases were
closed in 1991 and 2013, hazardous material contamination from the on-site gasoline USTs is no
longer occurring, and previous contamination has been addressed to the satisfaction of SWRCB.
Although the project site is listed on a Government Code Section 65962.5 list for LUSTs, these
previous LUST cases have been adequately remediated, closed, and no longer pose a significant
hazard to the public or the environment. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
e. For a project located within an airport land use plan or, where such a plan has not been
adopted, within two miles of a public airport or public use airport, would the project result in a
safety hazard or excessive noise for people residing or working in the project area?
The Long Beach Airport is located 4.6 miles northwest of the project site, and the Los Alamitos Army
Airfield is located 1.4 miles northeast of the project site; however, this airfield is not open to the
public. The project site is not within the adopted Airport Comprehensive Land Use Plan for the Long
Beach Airport (Los Angeles County Airport Land Use Commission 2003). The proposed project would
have no impact.
NO IMPACT
f. Would the project impair implementation of or physically interfere with an adopted emergency
response plan or emergency evacuation plan?
The project would have no effect on an adopted emergency response plan or emergency evacuation
plan because it is an addition to an existing facility and would not block roads or interfere with
circulation. Therefore, the proposed project would have no impact.
NO IMPACT
g. Would the project expose people or structures, either directly or indirectly, to a significant risk
of loss, injury, or death involving wildland fires?
The project site is in an existing shopping center in an urbanized area of Seal Beach. Wildland fuels,
such as forest, chaparral, or annual grasslands do not occur on the project site or in the adjacent
areas. The proposed project would have no impact.

a. Would the project violate any water quality standards or waste discharge requirements or
otherwise substantially degrade surface or ground water quality?
Temporary site preparation, grading, and paving activities associated with construction of the
project could result in limited soil erosion that may degrade water quality. However, such
construction activities would be required to comply with the requirements of SBMC Chapter 9.20
(the City’s Stormwater Management Program). SBMC Chapter 9.20 is enforced by City officials
during the permit approval process. This chapter requires development projects to comply with the
Orange County Drainage Area Management Plan (DAMP) and properly store waste material, to
ensure the protection of water quality from stormwater runoff.
Because the project would be constructed in an asphalt pavement area, construction equipment
would largely be operated on pavement. This would reduce the potential for construction vehicles
to carry soil or dust onto adjacent streets, such as Seal Beach Boulevard and Westminster
Boulevard. Operation of the proposed project would not substantially alter the amount or type of
pollutants in stormwater runoff. Land use would not change, because the proposed new fueling
facilities would be added to the existing gasoline station at the site. Similar to existing conditions,
stormwater runoff would occur as sheet flow, which would be transmitted into subdrains that
would drain into a curb and gutter system. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
b. Would the project substantially decrease groundwater supplies or interfere substantially with
groundwater recharge such that the project may impede sustainable groundwater
management of the basin?
The proposed project would be constructed in an existing impervious area of the site currently
paved with asphalt. While some existing landscaped planters would be removed, new planters
would be constructed to replace those pervious areas. Therefore, the proposed project would not
increase the amount of impervious surface on site, or the resultant volume of water that is able to
infiltrate the ground. The proposed project would have no impact.

c.(iv) Would the project substantially alter the existing drainage pattern of the site or area,
including through the alteration of the course of a stream or river or through the addition of
impervious surfaces, in a manner which would impede or redirect flood flows?
As described above for criterion b), the proposed project would not increase the impervious surface
area on the project site. There would be no change to existing drainage patterns on the site. There
are no streams or rivers on the site. The proposed project would have no impact.
NO IMPACT
d. In flood hazard, tsunami, or seiche zones, would the project risk release of pollutants due to
project inundation?
The proposed project is not a 100-year flood zone (Federal Emergency Management Agency 2019).
There are no landlocked bodies of water near the project site that could seiche. The project site is
1.8 miles from the Pacific Ocean, and outside the mapped tsunami inundation area (California
Department of Conservation 2009). Additionally, hydrogen fuel is not a pollutant of concern
because water is comprised of hydrogen and oxygen. The proposed project would have no impact.
NO IMPACT
e. Would the project conflict with or obstruct implementation of a water quality control plan or
sustainable groundwater management plan?
A Groundwater Sustainability Agency has not been formed for the portion of the Coastal Plain of
Orange County Groundwater Basin located beneath the City of Seal Beach, and no Groundwater
Sustainability plan for this portion of the basin exists.
The Water Quality Control Plan (2019 Update) for the Santa Ana River Basin includes the City of Seal
Beach in the plan boundaries. This plan provides water quality objectives and Total Maximum Daily
Loads (TMDL) for pollutants in the plan area. As described above for criterion b), the proposed
project would not increase the impervious surface area on the project site. Therefore, there would
be no substantial change to precipitation and runoff infiltration and groundwater. The project would
not generate increased demand for water. As described above for criterion d), hydrogen is not a
pollutant of concern because water is comprised of hydrogen and oxygen. FCEVs using the hydrogen
fueling facilities would only emit water. Therefore, the proposed project would not conflict with the
water quality control plan. Impacts would be less than significant.

including the existing gasoline station on the project site. Therefore, the project would not
physically divide an established community and there would be no impact.

b. Would the project cause a significant environmental impact due to a conflict with any land use

The project site is designated as Commercial-Service under the City’s General Plan. This designation
supports a very broad range of convenience and consumer goods and personal services. These uses
are either located along streets with relatively heavy pedestrian traffic with stores close to the right-
of-way line, or establishments to which customers arrive by vehicle with stores set back from the
road to allow for parking. The City’s General Plan identifies the Seal Beach Shopping Center as an
existing functioning service commercial area (City of Seal Beach 2003). The project would be
considered a service commercial land use, with expanded services provided from the proposed
hydrogen fueling stations, which is not currently available at the existing fueling station. Therefore,
the proposed project would be consistent with the land use designation and future development of
the site area. As described throughout the Initial Study, there would be no significant environmental
impacts resulting from the proposed project with implementation of applicable mitigation
measures. Impacts would be less than significant.

these identified resource areas. The project site is an existing gasoline station and is part of a larger
shopping center in a developed area of Seal Beach. The site is not used for mineral extraction and
does not contain any known or designated mineral resources. The physical distance between the

noise levels? □ □ □ ■
Noise
Sound is a vibratory disturbance created by a moving or vibrating source, which is capable of being
detected by the hearing organs (e.g., the human ear). Noise is defined as sound that is loud,
unpleasant, unexpected, or undesired and may therefore be classified as a more specific group of
sounds. The effects of noise on people can include general annoyance, interference with speech
communication, sleep disturbance, and, in the extreme, hearing impairment (Crocker 2007).
The unit of measurement used to describe a noise level is the decibel (dB). However, the human ear
is not equally sensitive to all frequencies within the sound spectrum. Therefore, a method called “A-
weighting” is used to filter noise frequencies that are not audible to the human ear. A-weighting
approximates the frequency response of the average young ear when listening to most ordinary
everyday sounds. When people make relative judgments of the loudness or annoyance of a sound,
their judgments correlate well with the “A-weighted” levels of those sounds. Therefore, the A-
weighted noise scale is used for measurements and standards involving the human perception of
noise. In this analysis, all noise levels are A-weighted, and the abbreviation “dBA” identifies the A-
weighted decibel.
Decibels are measured on a logarithmic scale that quantifies sound intensity in a manner similar to
the Richter scale used for earthquake magnitudes. A 10 dB increase represents a 10-fold increase in
sound intensity, a 20 dB increase is a 100-fold intensity increase, a 30 dB increase is a 1,000-fold
City of Seal Beach
13980 Seal Beach Boulevard Hydrogen Fueling Facility Project
58
intensity increase, etc. Similarly, a doubling of a noise source, such as doubling of traffic volume,
would increase the noise level by 3 dB; a halving of the noise source would result in a 3 dB decrease.
Human perception of noise has no simple correlation with acoustical energy. The perception of
noise is not linear in terms of dBA or in terms of acoustical energy. Two equivalent noise sources
combined do not sound twice as loud as one source. It is widely accepted that the average healthy
ear can barely perceive changes of 3 dBA (increase or decrease); that a change of 5 dBA is readily
perceptible; and that an increase or decrease of 10 dBA sounds twice (half) as loud (Caltrans 2013).
Descriptors
The impact of noise is not a function of loudness alone. The time of day when noise occurs and the
duration of the noise are also important. In addition, most noise that lasts for more than a few
seconds is variable in its intensity. Consequently, a variety of noise descriptors has been developed.
The noise descriptors used for this analysis are the one-hour equivalent noise level (Leq) and the
community noise equivalent level (CNEL).
The Leq is the level of a steady sound that, in a stated time period and at a stated location, has the
same A-weighted sound energy as the time-varying sound. For example, Leq(1h) is the equivalent
noise level over a 1-hour period, and Leq(8h) is the equivalent noise level over an 8-hour period. Leq(1h)
is a common metric for limiting nuisance noise, whereas Leq(8h) is a common metric for evaluating
construction noise.
The CNEL is a 24-hour equivalent sound level. The CNEL calculation applies an additional +5 dBA
penalty to noise occurring during evening hours (i.e., 7:00 p.m. to 10:00 p.m.) and an additional +10
dBA penalty to noise occurring during nighttime hours (i.e., 10:00 p.m. to 7:00 a.m.). These
increases for certain times are intended to account for the added sensitivity of humans to noise
during the evening and night.
There is no precise way to convert a peak hour Leq to DNL or CNEL – the relationship between the
peak hour Leq value and the DNL/CNEL value depends on the distribution of traffic volumes during
the day, evening, and night. However, in urban areas near heavy traffic, the peak hour Leq is typically
2 to 4 dBA lower than the daily DNL/CNEL. In less heavily developed areas, such as suburban areas,
the peak hour Leq is often roughly equal to the daily DNL/CNEL. For rural areas with little nighttime
traffic, the peak hour Leq will often be 3 to 4 dBA greater than the daily DNL/CNEL value (SWRCB
1999). The project site is located in an urban area; therefore, the DNL/CNEL in the area would be
approximately 2 to 4 dBA higher than the peak hour Leq.
Propagation
Sound from a small, localized source (approximating a “point” source) decreases or drops off at a
rate of 6 dBA for each doubling of distance. Traffic noise is not a single, stationary point source of
sound. Over a time interval, the movement of vehicles makes the source of the sound appear to
emanate from a line (line source) rather than a point. The drop-off rate for a line source is 3 dBA for
each doubling of distance.
Vibration
Groundborne vibration of concern in environmental analysis consists of the oscillatory waves that
move from a source through the ground to adjacent structures. The number of cycles per second of
oscillation makes up the vibration frequency, described in terms of hertz (Hz). The frequency of a
vibrating object describes how rapidly it oscillates. The normal frequency range of most
Environmental Checklist
Noise
Initial Study – Mitigated Negative Declaration 59
groundborne vibration that can be felt by the human body is from a low of less than 1 Hz up to a
high of about 200 Hz (Crocker 2007).
While people have varying sensitivities to vibrations at different frequencies, in general they are
most sensitive to low-frequency vibration. Vibration in buildings, such as from nearby construction
activities, may cause windows, items on shelves, and pictures on walls to rattle. Vibration of building
components can also take the form of an audible low-frequency rumbling noise, referred to as
groundborne noise. Groundborne noise may result in adverse effects, such as building damage,
when the originating vibration spectrum is dominated by frequencies in the upper end of the range
(60 to 200 Hz). Vibration may also damage infrastructure when foundations or utilities, such as
sewer and water pipes, physically connect the structure and the vibration source (Federal Transit
Administration [FTA] 2018). Although groundborne vibration is sometimes noticeable in outdoor
environments, it is almost never annoying to people who are outdoors. The primary concern from
vibration is that it can be intrusive and annoying to building occupants and vibration-sensitive land
uses.
Descriptors
Vibration amplitudes are usually expressed in peak particle velocity (PPV) or RMS vibration velocity.
Particle velocity is the velocity at which the ground moves. The PPV and RMS velocity are normally
described in inches per second (in/sec). PPV is defined as the greatest magnitude of particle velocity
associated with a vibration event. PPV is often used in monitoring of blasting vibration because it is
related to the stresses that are experienced by buildings (Caltrans 2020).
Vibration limits used in this analysis to determine a potential impact to local land uses from
construction activities, such as blasting, pile-driving, vibratory compaction, demolition, drilling, and
excavation, are based on information contained in Caltrans’ Transportation and Construction
Vibration Guidance Manual and the Federal Transit Administration’s (FTA) Transit Noise and
Vibration Impact Assessment Manual (Caltrans 2020; FTA 2018). Maximum recommended vibration
limits by the American Association of State Highway and Transportation Officials (AASHTO) are
identified in Table 9.
Table 9 AASHTO Maximum Vibration Levels for Preventing Damage
Type of Situation Limiting Velocity (in./sec.)
Historic sites or other critical locations 0.1
Residential buildings, plastered walls 0.2–0.3
Residential buildings in good repair with gypsum board walls 0.4–0.5
Engineered structures, without plaster 1.0–1.5
Source: Caltrans 2020
Based on AASHTO recommendations, limiting vibration levels to below 0.2 in/sec PPV at residential
structures would prevent structural damage regardless of building construction type. These limits
are applicable regardless of the frequency of the source. However, as shown in Table 10 and
Table 11 potential human annoyance associated with vibration is usually different if it is generated
by a steady state or a transient vibration source.

As shown in Table 10, the vibration level threshold at which steady vibration sources are considered
to be distinctly perceptible is 0.035 in/sec PPV. However, as shown in Table 11, the vibration level
threshold at which transient vibration sources (such as construction equipment pass-bys) are
considered to be distinctly perceptible is 0.24 in/sec PPV. This analysis uses the distinctly perceptible
threshold for purposes of assessing vibration impacts.
Although groundborne vibration is sometimes noticeable in outdoor environments, it is almost
never annoying to people who are outdoors and the vibration level threshold for human perception
is assessed at occupied structures (FTA 2018). Therefore, vibration impacts are assessed at the
structure of an affected property.
Regulatory Framework
Federal Transit Administration
The FTA has recommended noise criteria related to traffic-generated noise in Transit Noise and
Vibration Impact Assessment that can be used to determine whether a change in traffic would result
in a substantial permanent increase in noise (FTA 2018). Table 12 shows the significance thresholds
for increases in traffic-related noise levels. These standards are applicable to project impacts on
existing sensitive receivers.

The FTA provides reasonable criteria for assessing construction noise impacts based on the potential
for adverse community reaction in their Transit and Noise Vibration Impact Assessment Manual
(FTA 2018). For residential, commercial, and industrial uses, the daytime noise threshold is 80 dBA
Leq, 85 dBA Leq, and 90 dBA Leq for an 8-hour period, respectively. These values are used in the
construction noise analysis as the thresholds as the City does not specify construction noise limits.
City of Seal Beach Municipal Code
Chapter 7.15 of the SBMC sets noise standards of 65 dBA at commercial properties at any time, 55
dBA at residential properties from 7:00 a.m. to 10:00 p.m., and 50 dBA at residential properties from
10:00 p.m. to 7:00 a.m.
Section 7.15.025 of the SBMC exempts construction noise when performed between 7:00 a.m. and
8:00 p.m. on weekdays, and between 8:00 a.m. and 8:00 p.m. on Saturday.
City of Seal Beach General Plan
The City’s General Plan contains a Noise Element which identifies and appraises existing noises in Seal
Beach and provides guidance to avoid noise-related impacts in the future. Table 13 below, shows the

Existing Noise Setting
The project site is currently developed with a convenience store, auto shop, and gasoline station.
Vehicle noise is the primary noise source on the project site. Other sources of noise include car
doors closing, people shopping, and fuel dispensers.
The primary noise source in the project area is roadway traffic noise on Seal Beach Boulevard and
Westminster Boulevard. Ambient noise levels are generally highest during the daytime and rush
hour unless congestion substantially slows speeds. Motor vehicle noise is characterized by a high
number of individual events, which creates sustained noise levels.
Measured noise levels (taken November 2002) at Westminster Boulevard west of Seal Beach
Boulevard were 69 dBA Lmax and 65 dBA Leq, and 65 dBA CNEL along both Seal Beach Boulevard and
Westminster Boulevard (City of Seal Beach 2003). Additionally, military aircraft overflights are
common in the City of Seal Beach; however, the project site is not within any of the designated
noise contours (City of Seal Beach 2003).
Sensitive Receivers
Noise exposure standards for various types of land uses reflect the varying noise sensitivities
associated with each of these uses. Noise sensitive receivers include residences, schools, hospitals,
rest homes, and long-term medical or mental care facilities (City of Seal Beach 2003). Noise-
sensitive receivers nearest to the project sites are residences located a minimum of 460 feet west of
the project site.

Methodology
Construction Noise
Construction noise was estimated using the FHWA Roadway Construction Noise Model (RCNM) (FTA
2018). RCNM predicts construction noise levels for a variety of construction operations based on
empirical data and the application of acoustical propagation formulas. Using RCNM, construction
noise levels were estimated at noise sensitive receivers near the project site. RCNM provides
reference noise levels for standard construction equipment, with an attenuation of 6 dBA per
doubling of distance for stationary equipment.
Variation in power imposes additional complexity in characterizing the noise source level from
construction equipment. Power variation is accounted for by describing the noise at a reference
distance from the equipment operating at full power and adjusting it based on the duty cycle of the
activity to determine the Leq of the operation (FTA 2018). Each phase of construction has a specific
equipment mix, depending on the work to be accomplished during that phase. Each phase also has
its own noise characteristics; some would have higher continuous noise levels than others, and
some have high-impact noise levels. In typical construction projects, grading activities generate the
highest noise levels because grading involves the largest equipment and covers the greatest area.
Construction would last less than one year and would include demolition, site preparation, grading,
building construction, architectural coating, and paving of the project site. Construction would not
require any blasting or pile driving. It is assumed that diesel engines would power all construction
equipment. For assessment purposes, and to be conservative, the loudest construction hour has
been used for assessment. The loudest construction activities typically occur during grading
activities. Therefore, noise levels are based on a potential construction scenario of one bulldozer,
one backhoe, and one concrete saw operating simultaneously during the grading phase. At a
distance of 525 feet, one bulldozer, one backhoe, and one concrete saw would generate a noise
level of approximately 64 dBA Leq (RCNM Calculations are included in Appendix B). The grading
phase was the only phase modeled in RCNM because it would be the loudest construction phase.
For residential, commercial, and industrial uses, the daytime noise threshold is 80 dBA Leq, 85 dBA
Leq, and 90 dBA Leq for an 8-hour period, respectively. The FTA residential, commercial, and
industrial daytime noise thresholds of 80 dBA Leq, 85 dBA Leq, and 90 dBA Leq for an 8-hour period,
respectively, are used in the construction noise analysis as significance thresholds as the City does
not specify construction noise criteria.
Groundborne Vibration
The City’s General Plan and Municipal Code do not contain criteria for vibration impacts or analysis.
Therefore, the threshold for structure damage applied to the project is from Caltrans’
Transportation and Construction Vibration Guidance Manual (Caltrans 2020), which lists 0.2 in/sec
PPV at residential structures as the limit that would prevent structural damage regardless of
building construction type, and lists 0.2 in/sec PPV as the distinctly perceptible vibration annoyance
potential criteria for human receivers.

a. Would the project result in generation of a substantial temporary or permanent increase in
ambient noise levels in the vicinity of the project in excess of standards established in the local
general plan or noise ordinance, or applicable standards of other agencies?
Construction
The nearest noise-sensitive receivers to project construction would include the residences located a
minimum 460 feet west of the project site. Over the course of a typical construction day,
construction equipment would be located as far as 590 feet to the nearest receivers. As the
equipment would move throughout the site during a normal construction day (e.g., from between
460 feet to 590 feet from the property line adjacent to the nearest receivers), a reasonable estimate
of the average distance during a day of the equipment to the nearest residences would be 525 feet
for construction on the project site (i.e., the approximate center of construction activity) for the
purposes of estimating a typical noise level that sensitive receivers would experience. At 525 feet,
one bulldozer, one backhoe, and one concrete saw would generate a noise level of approximately
64 dBA Leq (RCNM calculations are included in Appendix B). Therefore, construction noise levels
would not exceed the FTA daytime construction noise threshold of 80 dBA Leq (8-hour) at residential
sensitive receivers. Additionally, noise levels of 64 dBA is typical of the volume of normal
conversation (Centers for Disease Control and Prevention 2019). Therefore, construction noise
would not be a substantial increase in ambient noise levels typical of residential areas.
Similarly, project construction would occur at an average distance of 75 feet from the nearest
adjacent commercial property. At 75 feet, one bulldozer, one backhoe, and one concrete saw would
generate a noise level of approximately 81 dBA Leq (RCNM calculations are included in Appendix B).
Therefore, construction noise levels would not exceed the FTA daytime construction noise threshold
of 85 dBA Leq (8-hour) at commercial receivers.
According to the CalEEMod outputs for air quality and GHG emissions (Appendix A), the paving
phase of project construction would generate the greatest number of worker vehicle trips, with a
total of 18 worker trips that would occur per day. Assuming that all worker trips would occur during
the AM and PM peak hour, up to 18 peak hour trips would occur during the building construction
phase. In the vicinity of the project site, Seal Beach Boulevard has a measured average daily traffic
(ADT) count of approximately 24,000 trips, and Westminster Boulevard has an ADT of approximately
25,000 trips (City of Seal Beach 2012). Project construction would result in a less than 0.1 percent
increase in daily trips, which would less than double existing traffic, resulting in no noticeable
increase in traffic noise from construction trips.
Project construction would adhere to the hour limitations identified in the SBMC Noise Ordinance
related to construction noise, which restrict construction hours to between 7:00 a.m. and 8:00 p.m.
on weekdays, and between 8:00 a.m. and 8:00 p.m. on Saturday (SBMC Section 7.15.025).
Compliance with the City’s Noise Ordinance would ensure that construction noise does not disturb
residents during the times they are most likely to be home or during hours when ambient noise
levels are likely to be lower (i.e., at night). Construction noise impacts would be less than significant.
Operation
A confidential noise assessment was prepared that involved measuring the noise levels generated
by the proposed hydrogen fueling equipment. Measurements were conducted at an undisclosed
location where the proposed hydrogen fueling equipment is already installed and operational.
Measurements were conducted during both daytime operations and nighttime operations, as
equipment would operate more frequently during daytime when use is more common. Table 14

As described above, the nearest sensitive receptor to the project site is a residence located
approximately 460 feet west of the site. As Table 14 shows, noise levels generated by the
equipment would be 52 dBA at approximately 131 feet from the hydrogen fueling equipment. Noise
would attenuate to 41 dBA at 460 feet, where the nearest receptor is located. This is below the 55
dBA standard for residences set forth in Chapter 7.15 of the SBMC and in the City of Seal Beach
General Plan (refer to Table 13). Additionally, 41 dBA is well below the volume of normal
conversation, which is approximately 60 dBA (Centers for Disease Control and Prevention 2019).
Therefore, hydrogen fuel equipment would not increase ambient noise levels typical of residential
areas, which includes noises from conversations, cars, children playing, etc.
The nearest commercial property to the project site is located approximately 75 feet from the
center of the project site. Attenuation would result in a noise level of less than 58 dBA at the
nearest commercial property. This is below the 65 dBA threshold set forth in Chapter 7.15 of the
SBMC for noise at commercial properties.
FCEVs do not generate exhaust noise like conventional gasoline-powered cars. However, the
operation of FCEVs on roadways does generate traffic noise from the friction of tires on the road
surface, like conventional vehicles. The confidential noise assessment did not measure noise from
the vehicle trips arriving and departing hydrogen fueling facilities. As described in Section 17,
Transportation, the proposed project would generate eight vehicle trips during the AM peak hour (7
am to 9 am), 12 vehicle trips during the PM peak hour (4 pm to 6 pm), and approximately 80 daily
trips. Peak hours are likely when the most FCEV trips to the project site would occur, as refueling
would likely occur as accessory stop to regional commutes in the area.
According to Crocker (2007), traffic volumes must approximately double on roadway for a 2 to 3
dBA increase in traffic noise levels. In the vicinity of the project site, Seal Beach Boulevard has a
measured average daily traffic (ADT) count of approximately 24,000 trips, and Westminster
Boulevard has an ADT of approximately 25,000 trips (City of Seal Beach 2012). The additional 80
daily trips generated by the project would not double the existing large volume of traffic on these
roadways and the resultant noise level increase would be less than 0.1 dBA, which is below the 2
dBA threshold for operational traffic noise increases in areas where the existing ambient noise level
is 65 dBA. Therefore, FCEV trips generated by the project would not result in a noticeable increase in
traffic noise levels at receptors. Impacts would be less than significant.

LESS THAN SIGNIFICANT IMPACT
b. Would the project result in generation of excessive groundborne vibration or groundborne noise
levels?
Construction activities known to generate excessive ground-borne vibration, such as pile driving,
would not be conducted by the project. The greatest anticipated source of vibration during general
project construction activities would be from a large bulldozer, which may be used within 75 feet of
the nearest structures. A dozer would create approximately 0.089 in/sec PPV at a distance of 25 feet
(Caltrans 2020). This would equal a vibration level of 0.027 in/sec PPV at a distance of 75 feet.2 This
would be lower than what is considered a distinctly perceptible impact for humans of 0.2 in/sec
PPV, and the structural damage impact of 0.2 in/sec PPV. Therefore, temporary impacts associated
with construction equipment use would be less than significant.
Operation of the project would not generate groundborne vibration. Therefore, groundborne
vibration and noise impacts resulting from implementation of the project would be less than
significant.
LESS THAN SIGNIFICANT IMPACT
c. For a project located within the vicinity of a private airstrip or an airport land use plan or,
where such a plan has not been adopted, within two miles of a public airport or public use
airport, would the project expose people residing or working in the project area to excessive
noise levels?
The Long Beach Airport is located 4.6 miles northwest of the project site, and the Los Alamitos Army
Airfield is located 1.4 miles northeast of the project site; however, this airfield is not open to the
public. The project site is not within the adopted Airport Comprehensive Land Use Plan for the Long
Beach Airport (Los Angeles County Airport Land Use Commission 2003), nor is it located within the
aircraft noise impact area (65 dBA CNEL) of the Los Alamitos Army Airfield. The proposed project
would have no impact.

expansion of infrastructure or roads and does not include educational or large-scale employment
opportunities. The altered facility would provide additional fueling opportunities for the City of Seal

The proposed project would not involve the construction of new or expanded fire protection
facilities. The existing Orange County Fire Station 48 is located on the northern corner of the
intersection of Seal Beach Boulevard and North Gate Road, approximately 0.9 mile north of the
project site. Given its proximity to the site, the Fire Department would respond to a fire on-site
within minutes. Therefore, no new fire protection facilities would be required to maintain
acceptable response times.
Operation of the proposed project would not result in increased demand for fire protection services.
Although hydrogen is flammable, the proposed project includes emergency shutoff valves to stop
fuel flows if there is ignition. Additionally, the proposed hydrogen fueling system design is required
to conform with the National Fire Protection Association (NFPA) 2 – Hydrogen Technologies Code
[2020]. Conformance with the NFPA 2 reduces the severity of hydrogen fires, especially to offsite
property or people. The Orange County Fire Authority would review project plans prior to issuance
of building permits to ensure compliance with all applicable fire and building safety codes.

a bus stop south of the site on Seal Beach Boulevard, which is served by OCTA Routes 42 and 42A.
The proposed project would add hydrogen fueling facilities to the existing gasoline station on the

Pedestrian facilities in the project area consist of sidewalks along the streets in the immediate
vicinity of the project site. Crosswalks and pedestrian push buttons are located at the signalized
intersection of Seal Beach Boulevard and Westminster Boulevard adjacent to the project site. The
proposed project would not modify existing site access driveways and would not require temporary
closure of sidewalks along the project site frontage. Impacts would be less than significant.

b. Would the project conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision
(b)?
Section 15064.3 of the CEQA Guidelines provides guidance on evaluating a project’s transportation
impacts. According to Section 15064.3, vehicle miles traveled (VMT) is generally the most
appropriate measure of transportation impacts, with the exception of projects consisting of the
addition of travel lanes to roadways. VMT refers to the amount and distance of automobile travel
attributable to a project, regardless of the type of vehicle or number of occupants in a vehicle.
Section 15064.3(b) establishes metrics and thresholds by which VMT can be evaluated for land use
projects and transportation projects.
The proposed project would add hydrogen fueling facilities to an existing gasoline station. The
hydrogen fueling facilities would be used exclusively by FCEVs. Based on trip generation information
for similarly sized hydrogen fueling facilities at existing gas stations, the proposed project would
generate eight vehicle trips during the AM peak hour (7 am to 9 am) and 12 vehicle trips during the
PM peak hour (4 pm to 6 pm) (Hexagon Transportation Consultants, Inc. 2020). Peak hours are likely
when the most FCEV trips to the project site would occur, as refueling would likely occur as an
accessory stop to regional commutes in the area. Approximately 80 daily trips to the hydrogen
fueling stations would occur.
It is expected that as the number of hydrogen-powered vehicles increases, the number of gasoline-
powered vehicles will decrease proportionately. Therefore, total vehicle trips to gas stations could
remain unchanged. In addition, the City of Seal Beach Transportation Analysis Guidelines (2020)
states that small projects, which would generate fewer than 250 daily trips, meet the City’s
screening criteria for VMT analyses, and impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
c. Would the project substantially increase hazards due to a geometric design feature (e.g., sharp
curves or dangerous intersections) or incompatible use (e.g., farm equipment)?
The proposed project would include minor modifications to the southwestern driveway to the site,
such as new curb and gutter along the driveway. However, the location and travel pattern of the
driveway would not be changed. The proposed project would not change traffic circulation patterns.
The hydrogen fueling facilities would be used for FCEVs, which operate and travel at speeds
consistent with conventional vehicles on roadways. The proposed project would have no impact.
NO IMPACT
d. Would the project result in inadequate emergency access?
The proposed project would change no emergency access routes and would maintain emergency
vehicle access and adequate turning radius for emergency vehicles within the project site. There
would be no impact.

Environmental Checklist
Tribal Cultural Resources
Initial Study – Mitigated Negative Declaration 77
As an existing gasoline station that is within a shopping center, there are no known Tribal Cultural
Resources within the project site. However, there are known Tribal Cultural Resources in the region,
such as Native American villages. The Village of Puvungna is located approximately 1.0 mile north of
the project site and is a sacred site of the Tongba nation and Acjachemen, who are the indigenous
people around Los Angeles and Orange County. Two other prehistoric Native American villages are
present to the south of the site. Given the distance between these villages and the project site,
there is low potential for project construction activities to uncover associated Tribal Cultural
Resources. Additionally, as described in Section 5, Cultural Resources, the project would involve
construction within a fully developed and previously disturbed site. Construction of the existing
gasoline station on the site required excavation and disturbed native soils, reducing the potential for
subsurface cultural resources to remain intact on-site. For example, the existing gasoline station
includes below ground storage tanks and pipeline trenches, which required excavations to greater
depths than would be required for the proposed project. However, there is always possibility for
intact resources or undocumented human remains or other Native American artifacts to be
discovered during construction. If encountered, construction could damage or destroy these
resources or remains. However, the project would be required to implement the mitigation
measures listed in Section 5, Cultural Resources. These conditions require contacting the NAHC, as
well as protecting resources in place until further evaluation and protection, as applicable, are
implemented. With these measures, impacts would be less than significant.
Additionally, the City will complete request(s) for consultation with California Native American
Tribes traditionally and culturally affiliated with the project area during the CEQA process.
The request for consultation will be completed prior to potential adoption of this Initial Study-
Mitigated Negative Declaration. The City will send notification letters to the California Native
American Tribes that requested inclusion on the City’s AB 52 notification list.

c. Would the project result in a determination by the wastewater treatment provider which serves

in addition to the provider’s existing commitments?
The proposed project consists of hydrogen fueling facilities for FCEVs. The hydrogen fuel facilities,
such as the fuel dispensers, would generate no wastewater. While stopped at the gasoline station,
FCEV customers may choose to use restroom facilities at the existing convenience store on the site.
The estimated 40 customers per day3 when the project first becomes operational would not be a
substantial generator of wastewater, as it would be only an incremental increase in the number of
restroom visits. It is unlikely every customer using the hydrogen fueling facilities would utilize the
restroom. As the popularity of FCEVs increases and more people utilize the proposed hydrogen
fueling facilities, the net number of customers to the site would remain relatively consistent with
existing conditions, as FCEVs would replace conventional cars. Accordingly, the proposed project
would not generate wastewater in excess of existing treatment capacity. Impacts would be less than

The proposed project consists of hydrogen fueling facilities for FCEVs. Refueling FCEVs would

customers may choose to discard small amounts of solid waste from their vehicles or from goods
purchased in the existing convenience store on the site. However, the estimated 40 customers per

As descried in Section 4, Biological Resources, the proposed project would have no impact on fish or
wildlife or plant communities. This is because the project site is currently a gasoline station with a
convenience store and auto shop. The site is part of a larger shopping center and adjacent to
roadways.
As described in Section 5, Cultural Resources, the project site has been disturbed and developed in
the past with the current gasoline station and associated uses. This development required ground
disturbance and excavation. Therefore, the potential to encounter cultural resources during

Initial Study – Mitigated Negative Declaration 85
excavation required for the proposed project is low. Standard mitigation measures for the
unanticipated discovery of cultural resources (as described in Section 5, Cultural Resources) would
be implemented in the event of encountering a resource and would reduce impacts to less than
significant. Mitigation measures for cultural resources would also apply to Tribal Cultural Resources,
if encountered during construction (as described in Section 18, Tribal Cultural Resources). Impacts
to Tribal Cultural Resources would be reduced to less than significant with implementation of
mitigation measures.

b. Does the project have impacts that are individually limited, but cumulatively considerable?
(“Cumulatively considerable” means that the incremental effects of a project are considerable
when viewed in connection with the effects of past projects, the effects of other current
projects, and the effects of probable future projects)?
The proposed project involves minimal construction disturbance at an existing gasoline station. As
described throughout this document, impacts of construction would be less than significant either
with or without mitigation. Operation of the project would involve minor increases in noise,
generally limited to the project site and within surrounding roadways. There are two other known
projects in the City of Seal Beach currently undergoing the review and approval process, including a
new gas station at 490 Pacific Coast Highway and a new gas plant at the Hellman Ranch property.
Both of these sites are located more than one mile from the project site; therefore, temporary
construction impacts are not likely to cause cumulatively considerable impacts, should construction
of these projects occur simultaneously. Additionally, the minor increases in traffic associated with
operation of these projects would not result in a cumulative traffic impact, as the total combined
trips generated on each roadway would be minimal, and mitigated as necessary in each project’s
environmental document. Therefore, impacts of the proposed project would not be cumulatively
considerable. Impacts would be less than significant.
LESS THAN SIGNIFICANT IMPACT
c. Does the project have environmental effects which will cause substantial adverse effects on
human beings, either directly or indirectly?
In general, environment effects which can be adverse human beings are associated with air quality,
hazards and hazardous materials, noise, and wildfire. As discussed in Section 3, Air Quality, the
project would not conflict with an air quality plan, result in cumulatively considerable net increase in
pollutants, or expose sensitive receptors to substantial concentrations of pollutants or odors.
A discussed in Section 9, Hazards and Hazardous materials, construction of the proposed project
could result in additional hazardous materials routine transport; however, compliance with
applicable federal, state, and local laws and regulations is required, which would ensure no adverse
effects on human beings as a result. Additionally, although the site is located on two prior LUST
cases, both cases are closed. Explosion or fire hazards would be reduced by required project design
features, such as wall enclosures and property line setbacks, per NFPA 2 requirements. Therefore,
impacts to humans from hazards and hazard materials would be less than significant.
As discussed in Section 13, Noise, neither construction nor operation the proposed project would
result in substantial increases in ambient noise levels at the nearest sensitive receptors. Likewise,
groundborne vibration generate during construction would not exceed FTA standards at the nearest

residence to the project site. Impacts to humans from noise and vibration would be less than

The project site is not in or near state responsibility areas or lands classified as very high fire hazard
severity zones. The nearest state responsibility area or lands classified as very high fire hazard
severity zones are approximately 10 miles away from the project site (California Department of
Forestry & Fire Protection 2011). The project site is a developed gasoline station consisting primary
of asphalt and structural concrete. Large open asphalt parking lots are adjacent to the north and
west of the site, and relatively wide roadways are to the south and east. The project site is not
adjacent to wildland fuels, such as forest, chaparral, or annual grasslands. Therefore, the proposed
project would have a less-than-significant impact on humans related to wildfire.
