Subject: 1242 20th Street Wellness Center Project Responses to Lozeau Drury Letters (November 3, 2021 and February 2, 2022)
Date: February 9, 2022

Attachment(s): Bracketed November 3, 2021 and February 2, 2022 Comment Letters The responses provided below address comments submitted by the law firm, Lozeau Drury, on behalf of Supporters Alliance for Environmental Responsibility (SAFER) on the Final Environmental Impact Report (SCH #2018011001) prepared for the 1242 20th Street Wellness Center Project (Project). The first letter was submitted at the November 3, 2021 Planning Commission hearing with a follow up letter dated February 2, 2022, responding to the City’s initial responses to their November 3, 2021 letter. The responses below address comments in the attached bracketed letters which include the attached exhibits.

Responses to November 3, 2021 Letter
Comment 1-1:

As summarized, the comment provides an opinion that the Final EIR fails as an informational document, fails to adequately analyze the Project’s environmental impacts, and fails to impose all feasible mitigation measures to reduce the Project’s impacts. The comment requests a revised EIR be prepared and recirculated prior to considering approvals for the Project.

Response to Comment 1-1:

The commenter’s opinion is noted and forwarded to the decision makers for consideration. The responses provided to this letter address all of the concerns regarding the adequacy of the Final EIR raised by the commenter. None of the issues raised in the comment letter constitute “significant new information” as defined in Section 15088.5 of the CEQA Guidelines. “Significant new information” requiring recirculation of an EIR includes, for example, a disclosure showing that:
(1) A new significant environmental impact would result from the project or from a new mitigation measure proposed to be implemented.
(2) A substantial increase in the severity of an environmental impact would result unless mitigation measures are adopted that reduce the impact to a level of insignificance. (3) A feasible project alternative or mitigation measure considerably different from others previously analyzed would clearly lessen the environmental impacts of the project, but the project’s proponents decline to adopt it.

(4) The draft EIR was so fundamentally and basically inadequate and conclusory in nature that meaningful public review and comment were precluded. (Mountain Lion Coalition v. Fish and Game Com. (1989) 214 Cal.App.3d 1043.)
None of the issues raised in this comment letter provides information that substantively affects the analyses within the Final EIR or otherwise identifies where the public would have been deprived of a meaningful opportunity to comment on a substantial adverse environmental effect of the proposed Project or a feasible way to mitigate or avoid such an effect. Therefore, recirculation of the EIR is not warranted or appropriate.

Comment 1-2:

The comment is summarized to note the Final EIR’s conclusion that Alternative 4 is infeasible because it does not meet the Project’s economic objective falls short of what is required under CEQA and the analysis of this alternative is inadequate because it does not provide substantial evidence to conclude Alternative 4 is infeasible.

Response to Comment 1-2:

Regarding Alternatives to the proposed Project, it is important to note that with the incorporation of mitigation measures, as set forth in the Final EIR, the proposed Project would not result in any significant environmental impacts. Chapter 6 of the Final EIR evaluates six Project alternatives, including the required No Project alternative, per Section 15126.6(e) of the CEQA Guidelines. CEQA requires an EIR to describe a range of alternatives to the project which would feasibly attain most of the basic project objectives and would avoid or substantially lessen any significant impacts of a project (Section 15126.6(a)). As discussed on page 6-1 of the Final EIR, Section 15126.6(a) of the CEQA Guidelines notes there is no ironclad rule governing the nature or scope of the alternatives to be discussed other than the rule of reason. This rule is described in Section 15126.6(f) of the Guidelines and requires the EIR to set forth only those alternatives necessary to foster informed decision-making. As defined in Section 15126.6(f), the rule of reason limits alternatives analyzed to those that would avoid or substantially lessen one or more of the significant effects of a project. Of those alternatives, an EIR need examine in detail only the ones that the lead agency determines could feasibly attain most of the basic objectives of the project. The Guidelines go on to state “[a]mong the factors that may be taken into account when addressing the feasibility of alternatives are site suitability, economic viability, availability of infrastructure, general plan consistency, other plans or regulatory limitations, jurisdictional boundaries ...”. The Alternatives analysis in an EIR is explicitly for the purpose of reducing or eliminating significant environmental impacts, and the proposed Project does not result in any significant impacts. While no significant and unavoidable Project impacts were identified, the alternatives selected for analysis in this EIR provide a robust evaluation of numerous options, which were selected to inform the decisionmaking process.

Alternative 4, Tier 1 (Reduced Project) Alternative calls for adaptively reusing the vacant portion of one of the existing buildings on the site (GKGM Building) and developing a new 33,750 square foot (sf) building adjacent, as compared to a 72,812 sf building under the proposed Project. Alternative 4 represents a reduction of approximately 39,000 sf when compared to the proposed Project by developing a smaller building area. This alternative would generally meet most of the objectives identified for the proposed Project and would reduce the severity of Project impacts. However, this alternative would not generate local tax revenue, provide new construction jobs, or house new residents to support local businesses to the same degree as the Project and therefore would not meet the Employment, Economic, and Fiscal Benefits objective as well as the Project. The commenter is raising the question of feasibility of approving an alternative that would result in fewer economic benefits as the Project and if this would be considered “sufficiently severe” as to make it infeasible to adopt this alternative. Feasibility under CEQA encompasses “desirability,” to the extent that desirability is based on a reasonable balancing of the relevant economic, environmental, social, legal, and technological factors. (City of Del Mar, supra, at p. 417.) Approval of a project with significant impacts requires findings be made by the lead agency pursuant to CEQA, and the CEQA Guidelines (California Code of Regulations, Title 14, Chapter 3 Sections 15043, 15091, and 15093). For

MEMORANDUM

10179 3 FEBRUARY 2022
each significant environmental effect identified in an EIR for a project, the lead agency must issue a written finding reaching one or more of three permissible conclusions. (CEQA Guidelines Section 15091.) The permissible conclusions are:

1. Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment;

2. Those changes or alterations are within the responsibility and jurisdiction of another public agency and have been, or can and should be adopted by that other agency;

3. Specific economic, legal, social, technological or other considerations for the provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or alternatives identified in the environmental impact report. (Pub. Resources Code Section 21081; CEQA Guidelines Section 15091.)
The City is required to prepare the Findings of Fact for those impacts that can be reduced to less than significant with mitigation and a Statement of Overriding Considerations for any significant and unavoidable impacts. The lead agency must consider the Final EIR and the all the evidence in the record to determine if the overriding economic, legal, social, technological and other benefits of the Project outweigh the significant and unavoidable effects of the Project, including alternatives. Absent any significant and unavoidable impacts it is up to the discretion of the City Council, as lead agency, to review all the substantial evidence provided in order to make the final determination to approve the Project or a Project alternative.

Comment 1-3:

The comment is summarized as follows: concerns are raised regarding addressing off-gassing of formaldehydebased glues and states the impacts to future Project employees needs to be analyzed in the EIR and mitigation measures should be imposed to reduce the risk of formaldehyde exposure. The comment also references mitigation measures (see also Exhibit A).

Response to Comment 1-3:

The Project is proposing development of a commercial property that includes employees and not residents.

Employees are not considered sensitive receptors under CEQA but are covered by the standards and protocols of the Occupational Health and Safety Administration (OSHA). The South Coast Air Quality Management District (SCAQMD) defines sensitive receptors as people who are most likely affected by air pollution, which includes the elderly and people with cardiovascular and chronic respiratory diseases. Sensitive receptors include residences, schools, playgrounds, childcare centers, long-term healthcare facilities, rehabilitation centers, convalescent centers, and retirement homes (SCAQMD 1993). The City’s CEQA Guidelines, State CEQA Guidelines, and California’s air district guidelines, including the SCAQMD guidelines do not require an analysis of indoor air quality which could result in potential impacts to future employees associated with new construction. California air districts’ including the SCAQMD develop CEQA thresholds of significance based on scientific and factual data specific to what the air basin can accommodate without affecting the attainment date for state and federal ambient air quality standards (AAQS). The AAQS is based on maximum pollutant levels for outdoor air quality that would not result in harm to the public’s health. Furthermore, building materials are required to reduce exposure to toxic substances through compliance with the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) regulations, such as 40 CFR Part 770, Formaldehyde Emission Standards for Composite Wood Products.

These regulations typically apply to manufacturers, distributors, importers, fabricators, and retailers of the products.

All building materials used to construct the Project would be required to comply with the applicable federal and state standards.

In addition, the Project is required to comply with the 2019 CALGreen Code, which specifies that composite wood products (such as hardwood plywood and particleboard) meet the requirements for formaldehyde as specified in

MEMORANDUM
SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 4 FEBRUARY 2022
CARB’s Air Toxic Control Measures. The 2019 CALGreen building code also does not allow added formaldehydebased resins or ultra-low emitting formaldehyde resins and requires documentation of compliance with CARB’s Air Toxic Control Measures. (See Section 5.504.4.5, Chapter 5, Part 11, 2019 California Green Building Standards Code, July 2019, incorporated herein by this reference.) Furthermore, the commenter is speculating that composite wood materials would be used in the interior of the building. The types of interior building materials would not be known until the building permit stage, and as stated above, these materials would be required to comply with CARB regulations and the 2019 CALGreen building code. There is no substantial evidence that the Project would involve use of materials that contain formaldehyde in levels that pose a risk to human health.

The commenter’s conclusions were not based on the assumption that the Project would be constructed in accordance with CARB’s Air Toxic Control Measures and the 2019 CALGreen building code. The commenter provides no evidence to substantiate a contrary conclusion that in spite of the Project using materials that comply with CARB’s standards for Air Toxic Control Measures, the Project would still expose employees to toxic substances that exceed the SCAQMD’s CEQA significance health risk threshold.

The Final EIR evaluates and discloses potential impacts to air quality associated with construction and operation of the Project. The commenter’s assertion that future employees could be at risk for carcinogens associated with offgassing of products containing formaldehyde constitutes speculation, not substantial evidence and is not required to be evaluated in a CEQA document. Finally, CEQA Guidelines Section 15126.4(B), states “compliance with a regulatory permit or other similar process may be identified as mitigation if compliance would result in implementation of measures that would be reasonably expected, based on substantial evidence in the record, to reduce the significant impact to the specified performance standards.” This comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-4:

A summary of the comment alleges the Final EIR incorrectly estimated the Project’s construction and operational emissions because the analysis relies on default values used in the model (CalEEMod.2016.3.2) that are not consistent with information in the Final EIR.

Response to Comment 1-4:

As identified in the CalEEMod User's Tips documentation, "Users are encouraged to understand the defaults and provide site specific data (e.g., construction schedule, construction equipment type, results of traffic study, predicted water usage, etc.), if available, for a more accurate analysis" (CAPCOA 2017). As such, changes to the default CalEEMod assumptions for Project emissions modeling were appropriate and based on input from the Project applicant and Project-specific information.

CalEEMod provides default values for input parameters such as for medical office and research/development building square footage. After basic project characteristics and land use information is inputted, CalEEMod provides default values so that the model may still be used to evaluate emissions from a land use development project in the event that such detailed information is not yet known (for instance, for a project in the planning stage). Similarly, CalEEMod provides a host of default values for the construction emissions analysis. Construction default values were used where Project information was not readily available. Default inputs that were updated according to information provided by the Project applicant included construction schedule phase lengths for major activities (e.g., demolition, grading, building construction, paving, and architectural coating); construction equipment lists for these major activities and hours of usage per day; construction truck and vehicle worker trips; and grading/excavation quantities. The construction methodology including information provided by the Project applicant are provided in the Final EIR beginning on page 4.2-30 in Section 4.2.4, Methodology.

Furthermore, the Project applicant and their contractor(s) represent ‘experts’ in estimating construction activities based on their experience with similar projects and their need to estimate construction activities, such as duration

SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 5 FEBRUARY 2022
of construction and equipment needed for budgeting purposes. Substantial evidence is defined under CEQA to mean “facts, reasonable assumptions predicated on facts, and expert opinion supported by facts” (CEQA Guidelines Section 15384(b)). Because assumptions provided the Project applicant and their team represent an expert opinion supported by facts, these assumptions constitute substantial evidence under CEQA that can be used to more accurately estimate Project-generated emissions.

Regarding operations, Project-specific data was used from the EIR’s transportation analysis including the Project’s trip generation. The emissions estimates also assume compliance with regulations (state or local) which take into account certain input variables such as compliance with building energy standards and utility renewable energy standards, as adopted by the state, some of which are not currently programmed into the model by default since many laws have been updated since release of the most current model. Therefore, the use of Project-specific data in CalEEMod is appropriate and fully in line with the CalEEMod User’s Guide. Information on the Project’s air emissions obtained from CalEEMod and relied on in the Final EIR is based on substantial evidence and is adequate as presented. This comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-5:

The comment, as summarized, identifies five default values relied on for the air quality modeling and claims these values were either inconsistent with other information in the Final EIR or unjustified.

Response to Comment 1-5:

Each of the five default values are identified and discussed below.

Unsubstantiated Reduction to Acres of Grading Value
The commenter states that the justification fails to substantiate changes to the Project’s acres of grading and the CalEEMod model underestimated the Project’s construction-related emissions. The Project’s total acres of grading was accurately estimated in CalEEMod, which is based on site specific information. As discussed in Chapter 3.0, Project Description of the Final EIR, the total site includes 1.03 acres, which includes two parcels: 1925 Arizona Avenue and 1242 20th Street. As such, 1.03 acres would be subject to grading/shoring activities during construction of the Project. Contrary to the commenter's assertion, the text included from the CalEEMod User Guide does not demonstrate an insufficiency regarding the analysis presented in the Final EIR. The total net acreage to be graded of 1.03 acres, as provided by the Project applicant, was used to determine the total area to be graded during the grading phase of the Project. Furthermore, the purpose of the SCAQMD guidance is to estimate the maximum acres of grading per day to determine the daily thresholds for the localized significance thresholds (LST) analysis. The text emphasized by the commenter appears to expressly condone the use of the total area to be graded as a means of determining the amount of grading needed on the site. Furthermore, the grading phase is assumed to occur over an 8-month duration, with multiple pieces of construction equipment working within the Project site for the duration of the Project’s construction. An 8-month grading period with multiple pieces of equipment working within the site, represents a reasonable, if not conservative, approach to analysis for grading a total of 1.03 acres. Therefore, the model was accurately updated based on site specific information provided by the Project applicant and the Final EIR’s analysis is adequate as presented.

Unsubstantiated Off-Road Construction Equipment Usage Hours The proposed Project’s off-road construction equipment unit amounts and usage hours are based on Project specific information provided by the Project applicant, as described on page 4.2-32, Construction, in the Air Quality section of the Final EIR. Not only are changes to the model default values based on acceptable and industry standard, but the changes result in a more accurate assessment of Project-generated construction and operational emissions because the values are based on Project-specific information. As specifically identified in the CalEEMod User's Tips documentation, "Users are encouraged to understand the defaults and provide site specific data (e.g.,

MEMORANDUM
SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 6 FEBRUARY 2022
construction schedule, construction equipment type, results of traffic study, predicted water usage, etc.), if available, for a more accurate analysis" (CAPCOA 2017). As such, the changes to the default CalEEMod assumptions for the project emissions modeling were appropriate based on applicant input and Project-specific information. For example, the commenter questions changes made to the construction equipment hour usage equipment assumptions, which were all based on applicant-provided information in consultation with a construction contractor.

Therefore, the Final EIR’s analysis is adequate as presented.

Failure to Substantiate Demolition and Reduction to Number of Demolition Hauling Trips CalEEMod provides default values for input parameters such as for a medical office and research/development building square footages. After the minimum project characteristic and land use information is inputted, CalEEMod provides default values so that the model may still be used to evaluate emissions from a land use development project in the event that such detailed information is not yet known (for instance, for a project in the planning stage).

Similarly, CalEEMod provides a host of default values for the construction emissions analysis. Construction default values were utilized where Project-specific information was not readily available. Default inputs that were updated according to information provided by the Project applicant include construction schedule phase lengths for major activities (e.g., demolition, grading, building construction, paving, and architectural coating); construction equipment lists for these major activities and hours of usage per day, construction truck and vehicle worker trips, and grading/shoring information. The construction methodology including information provided by the Project applicant are provided in the Final EIR beginning on page 4.2-29 in Section 4.2.4, Approach and Methodology of the Air Quality Section and beginning on page 4.6-29, Section 4.6.4, Approach and Methodology of the Greenhouse Gas Emissions Section of the Final EIR.

The number of haul truck trips required during the demolition phase was based on building square footage and pavement to be removed. The Project would involve the demolition of three buildings (rear garage, 3-unit building, and 7-unit building), and surface parking lot. Square footages for the existing buildings and pavement area were approximated using Google Earth. It was assumed that a total of approximately 10,755 sf of existing buildings and 15,552 sf of asphalt would be demolished and hauled off site. In order to estimate the number of haul trucks from pavement removal, CalRecycle’s Construction/Demolition and Inert Debris Tools and Resources rate of 2,400 pounds per cubic yard of debris for asphalt was used. Assuming a depth of 4 inches and an area of approximately

0.52 acres of pavement to be removed would result in a volume of approximately 335 tons of debris. Therefore, the overall number of haul trips resulting from construction of the Project was based on the building square footage and the approximate tonnage of asphalt debris, which was estimated to be 164 one-way haul trips. Therefore, the Final EIR’s analysis is adequate as presented.

Unsubstantiated Worker and Vendor Trip Numbers
Worker and vendor vehicle trips were based on CalEEMod default values. As discussed above, CalEEMod provides default values so that the model may still be used to evaluate emissions from a land use development project in the event that detailed information is not yet known (for instance, for a project in the planning stage). Similarly, CalEEMod provides a host of default values for the construction emissions analysis. Construction default values used in the assessment includes construction truck and vehicle worker trips. Defaults in CalEEMod are often inaccurate and do not take into account project specifics or local on-site conditions that may limit peak construction activities – for example, size of site and city requirements regarding the number of trucks that may travel to and from a project site during specific time frames and if equipment is to be staged onsite. However, the emissions analysis for this Project used Project-specific data to the extent information was available.

In addition, the commenter states that the “the justification provided by the User Entered Comments & Non-Default Data table only references hauling trips, not worker or vendor trips” is incorrect. Worker and vendor trips were rounded up based on CalEEMod default data and Project specific information. Furthermore, there are duplicate phases (i.e., grading 2 and building construction 2 and 3) assumed in the modeling in order to capture durations for specific construction equipment. Because those additional phases would be part of the overall main grading and building construction subphases, the worker, vendor, and haul trips are included in the main grading and

MEMORANDUM
SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 7 FEBRUARY 2022
building construction subphases and were zeroed out for those specific subphases (grading 2 and building construction 2 and 3). In addition, two vendor trucks were assumed during the main grading phase to account for water trucks (4 one-way trips). The commenter also states that the modeling should have included 39 workers being present on the Project site. As described in Chapter 3.0, Project Description, up to 4 to 39 construction workers would be on-site at any one time. The commenters statement is incorrect, as presented in Table 4.2-8 in Section

4.2, Air Quality, the lowest number of worker trips would be 8 one-way trips (4 round trips) which would occur during the demolition and grading phases. In addition, during building construction, the Project was estimated to have 78 one-way worker trips (39 round trips). Thus, the estimated 4 to 39 construction workers was based on CalEEMod modeling parameters used. Therefore, the use and update of CalEEMod default parameters is appropriate and the Final EIR’s analysis is adequate as presented.

Failure to Model Material Export
The Final EIR includes information on the approximate amount of material to be exported which is included in the Project’s construction emission calculations. As presented on page 4.2-30, Construction, in the Final EIR Air Quality Section, it was estimated the Project would require approximately 58,000 cubic yards of soil to be exported during grading/shoring activities. Grading information was based on grading plans provided by the Project applicant. The amount of soil to be exported during excavation/shoring activities has been reflected in the model. Grading activities are anticipated to be performed through the use of off-road construction equipment (e.g., grader and tractor/loader/backhoe) which would occur over approximately 8 to 9 months. Based on information provided by the Project applicant, 10 cubic yard trucks would be used. As discussed in the construction health risk assessment (HRA), Appendix B of the Final EIR, construction scenario assumptions, including phasing, equipment mix, and vehicle trips, were based on information provided by the Project applicant and CalEEMod default values. All assumptions pertaining to construction emissions, including phasing, equipment, and vehicle trips are based on Section 4.2 (Air Quality) of the Final EIR. For the HRA, diesel particulate matter (DPM) exhaust emitted from on-site construction equipment and diesel vehicles are of concern. Notably, to include only on-site emissions from diesel haul and vendor trucks, it was conservatively assumed these trucks would operate for 0.19-miles on site (1,000 feet) in the modeling.

Therefore, the Final EIR’s analysis is adequate as presented.

Comment 1-6:

To summarize the comment, the commenter states the Project’s construction HRA is incorrect due to the inputting of several incorrect values into the model and the HRA underestimates the concentration of diesel particulate matter (DPM) which underestimates the Project’s cancer risk.

Response to Comment 1-6:

The commenter uses a screening model known as AERSCREEN, to evaluate health risk impacts from diesel emissions during Project construction activities. While the AERSCREEN model is recognized as an acceptable model by the EPA and SCAQMD; however, it is considered a screening model. As a screening model, it overestimates impacts with the general understanding that if AERSCREEN does not show impacts, then impacts would also not occur if a more detailed analysis is conducted using a more refined model. AERSCREEN is a simplified model in that it does not consider meteorological data or topographical data. AERSCREEN assumes calm wind conditions at all times and a stable atmosphere (i.e., no atmospheric mixing). AERSCREEN also has simplified emissions input fields which typically overestimates emission impacts from varying construction activities.

Construction health risks were evaluated in the Final EIR using a more refined model recommended by EPA and SCAQMD to evaluate project effects, known as the American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD). This model takes into account meteorological data and topographical data. It also accounts for the geography of a project site, locations of emissions sources, the time of day emissions would occur, locations of sensitive receptors, and other factors to a much greater degree than AERSCREEN, which better represents the real world environment. The construction HRA prepared for the Project used the AERMOD model,

MEMORANDUM
SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 8 FEBRUARY 2022
which relied on methodologies provided by the SCAQMD and age sensitivity factors and other health risk evaluation parameters recommended by the SCAQMD and the Office of Environmental Health Hazard Assessment (OEHHA).

See Response to Comment 1-5 which addresses the validity of the adjusted inputs. The modeling results indicate that health risk impacts were determined to be less than the SCAQMD significance thresholds for cancer risk and non-cancer chronic risk for DPM after implementation of mitigation measure MM-AQ-1, which would require the use of Tier 4 interim equipment for all construction equipment greater than 75 horsepower. Use of Tier 4 construction equipment would ensure the Project’s construction-related health risk to nearby receptors would be less than significant. Therefore, the Final EIR’s analysis is adequate as presented.

Comment 1-7:

The comment is summarized to note that the commenter states the Project’s operational HRA, fails to quantitively evaluate toxic air contaminants (TACs) associated with Project operation and in doing so fails to connect TAC emissions to potential health risks to nearby receptors.

Response to Comment 1-7:

The Project would not result in a long-term source of TAC emissions. No residual TAC emissions and corresponding cancer risk are anticipated after construction, and no long-term sources of TAC emissions are anticipated during operation of the proposed Project. The CARB has published the Air Quality and Land Use Handbook: A Community Health Perspective (CARB 2005), which identifies certain types of facilities or sources that may emit substantial quantities of TACs and therefore could conflict with sensitive land uses, such as “schools and schoolyards, parks and playgrounds, daycare centers, nursing homes, hospitals, and residential communities.” The Air Quality and Land Use Handbook is a guide for siting of new sensitive land uses, but it does not mandate specific separation distances to avoid potential health impacts. CARB has identified the following facilities or sources of TACs:
• High-traffic freeways and roads
• Distribution centers
• Rail yards
• Ports
• Refineries
• Chrome plating facilities
• Dry cleaners
• Large gas dispensing facilities.

The proposed Project would not include any of the land uses listed above and would not be located near any of these uses potentially exposing sensitive receptors to TAC emissions from these sources. Furthermore, the commenter states that the Project would generate 100 truck trips per day. As presented in Appendix B of the Final EIR, the Project would result in approximately 1,287 weekday trips. Using the CalEEMod Version 2016.3.2 default fleet mixes for medical office and research/development land uses (2% for medium-heavy duty [MHD] trucks and

3.5% for heavy-heavy duty [HHD] trucks), the Project would result in approximately 71 truck trips per day. Therefore, based on the above considerations the Final EIR’s health risk analysis is adequate as presented.

Comment 1-8:

The comment, as summarized, references the Office of Environmental Health Hazard Assessment (OEHHA) 2015 guidance describing which types of projects warrant preparation of an HRA and if a project is expected to last over 6 months, the exposure should be evaluated using a 30-year exposure duration to estimate individual cancer risks.

The commenter recommends health risk impacts from the Project be evaluated.

MEMORANDUM
SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 9 FEBRUARY 2022
Response to Comment 1-8:

Regarding the assertion that construction and operational health risks should be based on a 30-year exposure duration, vastly exceeds the 6-month requirement set forth by OEHHA. As discussed in the construction HRA (Appendix B of the Final EIR), the construction HRA was performed in accordance with the OEHHA approved the 2015 Risk Assessment Guidelines Manual (OEHHA 2015). SCAQMD requires that all HRAs prepared for CEQA documents follow SCAQMD policies in conjunction with the 2015 Risk Assessment Guidelines Manual. For the purposes of the construction HRA, given the less-than-lifetime exposure period, and the higher breathing rates and sensitivity of children to construction-generated TACs, the cancer risk calculation assumes that the exposure would affect children early in their lives. For the residential health risk, the HRA assumes exposure would start in the third trimester of pregnancy and occur for 23 months, over the duration of construction activities. The Final EIR adequately evaluated the Project’s potential health risk impacts from construction and determined that they would be less than significant after implementation of mitigation measure MM-AQ-1. This comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-9:

As summarized in the comment, the Final EIR fails to evaluate the “cumulative lifetime cancer risk to nearby, existing receptors associated with Project construction and operation together.” The commenter requests the cumulative cancer risk posed by the Project’s construction and operation to nearby, existing receptors should be quantified and compared to the SCAQMD threshold of 10 in one million.

Response to Comment 1-9:

The SCAQMD nor OEHHA provides guidance requiring that construction and operational health risk be evaluated together. Based on an email from Michael Krause, Planning and Rule Manager with SCAQMD, who is an expert, a project’s construction and operational health risks need to be evaluated separately. Thus, the Project’s construction HRA is analyzed in accordance with industry guidance and, as discussed under Response to Comment 1-7 an operational HRA is not considered necessary for the Project. The cumulative effects associated with exposure over a 30-year period is addressed in Response to Comment 1-8.

Comment 1-10:

The commenter prepared a screening-level HRA to evaluate potential impacts from Project construction using AERSCREEN, a screening-level air quality dispersion model. The comment is summarized to note that based on this screening tool the lifetime cancer risk exceeds SCAQMD’s threshold of 10 in one million and the commenter states the Project may have a significant health impact as a result of diesel particulate emissions (DPM) and recommends additional analysis be conducted.

Response to Comment 1-10:

The commenter prepared a screening-level HRA using AERSCREEN and changed CalEEMod inputs with the assumption that health risks should be combined for construction and operation of the Project. First, the commenter subtracted the 676-day construction duration from the 30-year exposure duration, resulting in an operational exposure duration of 28.15 years. As previously discussed under Response to Comment 1-9, the SCAQMD nor OEHHA provides guidance requiring that construction and operational health risk be evaluated together; however, the commenter’s health risk calculations combine and evaluate both construction and operation cancer risks together. Further, the commenter states that the Project would result in 25 pounds of DPM during Project operations. The screening-level operational HRA prepared by the commenter’s scientists (Exhibit B of this Comment Letter) incorrectly correlates exhaust PM10 (coarse particulate matter) emissions generated by Project operational emission sources with DPM emissions. The commenter’s screening-level HRA calculates DPM emissions for diesel-fueled trucks associated with the Project. The DPM exhaust emission rate from the operational

MEMORANDUM
SUBJECT: RESPONSES TO LOZEAU DRURY COMMENT LETTER
10179 10 FEBRUARY 2022
phase of the Project used in the commenters health risk calculations is based on the exhaust PM10 annual emission rate from the Final EIR’s CalEEMod annual model runs. However, the exhaust PM10 emissions from CalEEMod do not directly correlate to DPM from operational emission sources. For instance, over 32% of operation-generated exhaust PM10 would be from natural gas combustion associated with building energy use. Natural gas combustion would not generate DPM, because diesel fuel is not part of the combustion process. In addition, the predominant mobile emission source associated with proposed medical office building research and development land uses would be gasoline-fueled passenger cars, and not diesel-fueled trucks. For these reasons, the exhaust PM10 emissions from the operational CalEEMod annual output cannot be directly correlated to DPM for the purposes of an HRA.

The HRA provided in the Final EIR used a refined air dispersion modeling approach (AERMOD), whereas a screeninglevel HRA was prepared by the commenter’s scientists. The SCAQMD recommends a more refined modeling analysis for projects which may exceed applicable thresholds. Refined models such as AERMOD require more site-specific information and yield greater characterization of the Project’s effects and more representative results. Therefore, the commenter has not provided any substantive comments or evidence that would alter model inputs or the findings of the emissions calculations in the Final EIR. As such, the use of the air quality modeling results is correct and is appropriately relied upon and no revisions to the Final EIR are required.

Comment 1-11:

The comment is summarized to state that the Final EIR’s analysis of greenhouse gas (GHG) emissions is flawed because the analysis relies on the Project’s consistency with CARB’s Climate Change Scoping Plan, Southern California Association of Governments (SCAG’s) 2020-2045 Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), and the City of Santa Monica’s Land Use and Circulation Element (LUCE), Sustainable City Plan, Green Building and Energy Code, and Climate Action and Adaptation Plan; uses an unsubstantiated model to quantify GHG emissions; and fails to consider performance-based standards under CARB’s Scoping Plan and SCAG’s RTP/SCS.

Response to Comment 1-11:

CEQA Guidelines Section 15064.4 states that a lead agency should make a good-faith effort, based on available information, to describe, calculate or estimate the amount of GHG emissions resulting from a project. A lead agency has the discretion to determine, in the context of a particular project, whether to: (1) use a model or methodology to quantify GHG emissions resulting from a project, and which model or methodology to use; or (2) rely on a qualitative analysis or performance-based standards. A lead agency may consider the following when assessing the significance of impacts from GHG emissions on the environment: (1) the extent to which the project may increase or reduce GHG emissions as compared to the existing environmental setting; (2) whether the project emissions exceed a threshold of significance that the lead agency determines applies to the project; and (3) the extent to which the project complies with regulations or requirements adopted to implement a statewide, regional, or local plan for the reduction or mitigation of GHG emissions. Such regulations or requirements must be adopted by the relevant public agency through a public review process and must include specific requirements that reduce or mitigate a project’s incremental contribution of GHG emissions. If there is substantial evidence that the possible effects of a particular project are still cumulatively considerable notwithstanding compliance with the adopted regulations or requirements, an EIR must be prepared for the project (CEQA Guidelines Section 15064.4).

As discussed in the Final EIR, the City has not adopted quantitative project-level significance thresholds for assessing impacts related to GHG emissions applicable to the proposed Project. In the absence of any adopted quantitative threshold, the determination of whether or not the Project would result in a cumulatively considerable contribution to the cumulative impacts of global climate change is based on applicable regulatory plans and policies to reduce GHG emissions, which include CARB’s Climate Change Scoping Plan; the SCAG 2020-2045 RTP/SCS; and the City’s Sustainable City Plan, Climate Action and Adaptation Plan, Green Building and Energy Code, and the

City’s LUCE. The GHG analysis is consistent with the CEQA Guidelines and adequately evaluates GHG impacts as required by CEQA.

The responses below address the four concerns raised by the commenter regarding the Final EIR’s approach to evaluating GHG impacts.

Incorrect and Unsubstantiated Quantitative Analysis of Emissions The comment is summarized to state that the quantitative GHG analysis relies on an “incorrect and unsubstantiated air model”. It is assumed the commenter is referring to the CalEEMod model used to quantify the Project’s GHG emissions. As described above under Response to Comment 1-6, all values inputted into the model were based on information provided by the Project applicant and/or were reasonable assumptions based on best available data and substantial evidence.

As previously discussed under Response to Comment 1-4, the CalEEMod User's Tips documentation states that, "Users are encouraged to understand the defaults and provide site specific data (e.g., construction schedule, construction equipment type, results of traffic study, predicted water usage, etc.), if available, for a more accurate analysis" (CAPCOA 2017). As such, the changes to the default CalEEMod assumptions for the Project emissions modeling were appropriate based on applicant input and Project-specific information.

CalEEMod provides default values for input parameters such as for medical office and research/development square footages. After the minimum project characteristic and land use information is inputted, CalEEMod provides default values so that the model may still be used to evaluate emissions from a land use development project in the event that such detailed information is not yet known (for instance, for a project in the planning stage). Similarly, CalEEMod provides a host of default values for the construction emissions analysis. Construction default values were used where Project information was not readily available. Default inputs that were updated according to information provided by the applicant include construction schedule phase lengths for major activities (e.g., demolition, grading, building construction, paving, and architectural coating); construction equipment lists for these major activities and hours of usage per day, construction truck and vehicle worker trips, and grading/shoring information. The construction methodology including information provided by the Project applicant is provided in the Final EIR beginning on page 4.2-29 in section 4.2.4, Approach and Methodology in the Air Quality Section.’ Project-specific information was applied to the CalEEMod model where appropriate and based on information obtained from the Project applicant regarding site-specific characteristics of the site and Project components. The Project applicant and their contractor(s) represent ‘experts’ in estimating construction activities for the Project based on their experience with similar projects and their need to estimate construction activities, such as duration of construction and equipment needed, for budgeting. Substantial evidence is defined in the CEQA statute to mean “facts, reasonable assumptions predicated on facts, and expert opinion supported by facts” (14 CCR 15384(b)).

Because assumptions provided the Project applicant and their team represent an expert opinion supported by facts, these assumptions constitute substantial evidence under CEQA that can be used to more accurately estimate Project-generated emissions.

Regarding operations, Project-specific data was used from the transportation analysis including the Project’s trip generation rates for each land use type. The emissions estimates also assume compliance with regulations (state or local) are also taken into account for certain input variables such as compliance with building energy standards and utility renewable energy standards, as adopted by the State of California, some of which are not currently programmed into the model by default since many laws have been updated since the release of the model.

Therefore, the use of Project-specific data in CalEEMod is appropriate and consistent with the CalEEMod User’s Guide; thus, the Final EIR’s analysis is based on substantial evidence and is adequate as presented. Additionally, as discussed on page 4.6-27 in Section 4.6, Greenhouse Gas Emissions, the quantitative emissions estimates are provided for informational purposes only and were not used to determine significance. The impact analysis is based solely on the Project’s consistency with applicable regulatory plans and policies to reduce GHG emissions, as discussed on page 4.6-33 of the Final EIR. The analysis of the Project’s GHG emissions adheres to industry guidance

and tools and accurately quantifies emissions. This comment does not establish any new information that would require revisions to the Final EIR.

Failure to Identify a Potentially Significant GHG Impact The comment is summarized to note that the commenter compares the Project’s estimated GHG emissions to their own “SCAQMD 2035 efficiency target”, and states that when applying this threshold, the “incorrect and unsubstantiated air model indicates a potentially significant GHG impact.” As discussed under Response to Comment 1-11, CEQA Guidelines Section 15064.4 states that a lead agency has the discretion to rely on a qualitative analysis or performance-based standards. As discussed in this response, quantitative emissions estimates for the Project were provided for informational purposes only and were not used to determine significance because neither CARB, SCAQMD, nor the City has adopted quantitative project-level significance thresholds for assessing impacts related to GHG emissions applicable to the Project. Project significance is based solely on the analysis of the Project’s consistency with applicable regulatory plans and policies to reduce GHG emissions, as discussed on page 4.6-35 under Section 4.6.5, Impact Analysis of the Final EIR. This approach is consistent with CEQA Guidelines Section 15064.4, which states that a lead agency has the discretion to rely on a qualitative analysis.

As discussed in the Final EIR, the City has not adopted quantitative project-level significance thresholds for assessing impacts related to GHG emissions. In the absence of any adopted quantitative threshold, the determination of whether or not the Project would result in a cumulatively considerable contribution to the cumulative impacts of global climate change is based on reviewing consistency with applicable regulatory plans and policies adopted to reduce GHG emissions, which include CARB’s Climate Change Scoping Plan; the SCAG 2020-2045 RTP/SCS; and the City’s Sustainable City Plan, Climate Action and Adaptation Plan, Green Building and Energy Code, and the City’s LUCE. The GHG analysis adequately evaluates GHG impacts as required by CEQA. This comment does not establish any new information that would require revisions to the Final EIR.

Failure to Consider Performance-based Standards Under CARB’s 2017 Scoping Plan (Item 3) A summary of the comment states that the Final EIR fails to evaluate the proposed Project’s consistency with CARB 2017 Scoping Plan performance-based daily vehicle miles traveled (VMT) per capita projections, and asserts that the Final EIR’s claim that the proposed Project would not conflict with the 2017 Scoping Plan is therefore unsupported.

CARB released the updated Mobile Source Strategy that demonstrates how the state can simultaneously meet air quality standards, achieve 2030 and 2050 GHG emission reduction targets, decrease health risk, and reduce petroleum consumption from the transportation sector. CARB developed a scenario-based modeling system that was used to identify foreseeable emission reductions associated with existing mobile-source regulations, and to explore different combinations of further advancements in technologies, fuels, and transportation system efficiencies. This modeling relates VMT and GHG metrics to each other and can be a useful source of information for planners considering projects using one or the other of these metrics. Specifically, in support of the Mobile Source Strategy, CARB developed two scenarios using the model that are particularly relevant with respect to GHG emissions from the transportation sector. Notably, the baseline scenario represents the mobile-source GHG emissions reductions associated with existing mobile-source controls, regulations, foreseeable deployment of technology, and current projections of VMT included in the existing RTP/SCSs adopted by the state’s 18 Metropolitan Planning Organizations pursuant to Senate Bill (SB) 375. Furthermore, the Cleaner Technologies and Fuels scenario evaluates what level of additional deployment of cleaner vehicle technologies and fuels combined with slower growth in VMT would be necessary to achieve state air quality targets and climate goals of 40% reduction in GHG emissions from 1990 levels by 2030 and 80% by 2050. The existing total VMT per capita (2015-2018 average) was 24.6 and the existing light-duty VMT per capita (2015-2018 average) was 22.2.

As discussed in Section 4.10, Transportation of the Final EIR, the City had not adopted local VMT significance thresholds at the time the Project’s VMT assessment was undertaken, including a VMT metric and significance criteria in compliance with SB 743 guidelines. A VMT analysis was included for the Project in the Final EIR for informational purposes. The City’s travel demand forecasting model (TDFM) includes data on the average daily trips, VMT, and trip length by trip purpose for each traffic analysis zone (TAZ), as well as the citywide averages. The Project is located in the Santa Monica TDFM TAZ 231. The average home-based work trip attraction in TAZ 231 and 230 is

11.4 miles, which is slightly lower than the City-wide average of 12.1 miles. The estimated employee trips were multiplied by the trip length and divided by the number of employees to calculate average VMT per employee. Thus 350 employee trips of 11.4 miles each equals 3,990 total daily miles. This equates to 11.4 VMT daily per employee which is about 40% less than the City-wide base year (2013) average of 19.3 daily VMT per employee. The 2013 base year values were used since this is the most recent validated TDFM model run. Furthermore, the average trip length for home-based other trip attractions and non-home-based trip attractions in TAZ 230 and 231 is 7.9 miles.

The average trip length for non-home-based trip productions in TAZ 230 and 231 is 3.7 miles.

Based on trip generation estimates in the Transportation Section of the Final EIR and data in the City’s travel demand forecasting model, the proposed Project’s estimated VMT per capita is 11.4 VMT per employee which is 40% less than the Citywide 2013 average of 19.3 VMT per employee. Based on Office of Planning and Research’s (OPR’s) review of the applicable research, and an assessment by the CARB, OPR recommends that a per capita or per employee VMT that is 15% below that of the existing development may be a reasonable threshold. Therefore, the Project meets Tier 3 of the City’s VMT screening criteria, no additional VMT analysis is required, and the Project is determined to have a less-than-significant VMT impact. Given the less-than-significant VMT impact, the GHG emissions from per capita VMT associated with the proposed Project are assumed to be consistent with the VMT goals of the 2017 Scoping Plan. The Project was found to be consistent with all applicable strategies and measures of the 2017 Scoping Plan, according to the consistency analysis starting on page 4.6-33 in Section 4.6, Greenhouse Gas Emissions of the Final EIR. This comment does not establish any new information that would require revisions to the Final EIR.

Failure to Consider Performance-based Standards Under CARB’s 2017 Scoping Plan (Item 4) The comment is summarized to note that the Final EIR fails to consider whether the proposed Project meets the specific performance-based goals of SCAG’s RTP/SCS and SB 375, including per capita GHG emission targets and daily per capita VMT benchmarks.

As discussed in the Final EIR on page 4.6-27, CEQA Guidelines Section 15064.4 states that lead agencies have the discretion to determine, in the context of a particular project, whether to: (1) use a model or methodology to quantify GHG emissions resulting from a project, and which model or methodology to use; or (2) rely on a qualitative analysis or performance-based standards. The significance of GHG impacts relating to the Project are based the applicable regulatory plans and policies adopted to reduce GHG emissions, which include CARB’s Climate Change Scoping Plan; the SCAG 2020-2045 RTP/SCS; and the City’s Sustainable City Plan, Climate Action and Adaptation Plan, Green Building and Energy Code, and the City’s LUCE. The GHG analysis is consistent with the CEQA Guidelines and adequately evaluates the Project’s GHG impacts.

As discussed in Section 4.10, Transportation of the Final EIR, the Project is estimated to generate 11.4 VMT daily per employee, approximately 40% less than the City-wide base year (2013). Based on OPR’s review of the applicable research, and an assessment by the CARB, OPR recommends that a per capita or per employee VMT that is 15% below that of the existing development may be a reasonable threshold. Therefore, the Project was determined to have a less-than-significant VMT impact. Given the less than significant VMT impact, the GHG emissions from per capita VMT associated with the proposed project are assumed to be consistent with the VMT goals of the 2017 Scoping Plan and SCAG’s 2020-2045 RTP/SCS. Furthermore, the Project’s impact assessment evaluates the consistency of the Project with plans adopted for the purpose of reducing GHG emissions separate from the quantitative analysis, which was used to determine if the Project’s GHG emissions would be potentially significant.

The Project was also found to be consistent with the applicable regulatory plans and policies to reduce GHG

emissions, including the emissions reduction measures discussed within 2017 Scoping Plan, Assembly Bill (AB) 32, EO S-3-05 and B-30-15, and SCAG’s 2020-2045 RTP/SCS. Moreover, the Project site is well served by public transit and is located in a Transit Priority Area as indicated by the City. Specifically, the Project site is approximately within a 0.7-mile walking distance from the 17th Street/Santa Monica College station of the Expo Light Rail Line and is well-served by bus transit service, including Big Blue Bus and Metro buses. The bus stops closest to the Project site are on 20th Street southbound and at the Wilshire Boulevard/20th Street intersection, which is served by Big Blue Bus Routes 2, 20, and 41. In general, the Project would be consistent with the overall intent of SB 743 to promote the reduction of GHGs, the development of multi-modal transportation networks, and a diversity of land uses.

Therefore, if the Project would not conflict with these plans, the City would be able to achieve its GHG reduction goals, and, therefore, these plans can be used at a project level to show that a project would not have a significant cumulative effect on the environment as it relates to GHG impacts.

As the substantial evidence provided on pages 4.6-33 through 4.6-45 of Section 4.6, Greenhouse Gas Emissions, of the Final EIR shows the Project would be consistent with the applicable provisions of these plans. Therefore, the Final EIR properly concludes, based on substantial evidence, that the Project’s GHG impacts are less than significant and mitigation measures are not required. This comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-12
The comment, as summarized, claims because the Project would result in GHG impacts all of the Project’s sustainability design features be implemented as formal mitigation measures and the air quality, GHG and HRA be revised and updated.

Response to Comment 1-12:

The proposed Project includes a number of sustainable design features listed on page 3-11 in Chapter 3.0, Project Description and referenced on page 4.6-32 in Section 4.6, Greenhouse Gas Emissions of the Final EIR. These features include implementation of a Transportation Demand Management (TDM) Plan per Chapter 9.53 of the City’s Municipal Code. In addition, the Project would be required to meet or exceed the City’s Green Building Standards and Energy Reach Code. The Project is already proposing to develop these design features as part of the Project design. An analysis of the Project’s GHG impacts factors in the Project’s sustainable design features along with compliance with state regulatory requirements help to reduce GHG emissions ensuring the Project would not exceed the SCAQMD’s significance threshold for construction or operation related emissions (FEIR p. 4.6-35).

Additionally, it is important to note, CEQA does not require adoption of every imaginable feasible mitigation measure. CEQA’s requirement applies only to feasible mitigation that will “substantially lessen” a project’s significant effects. (Public Resources Code, § 21002.) As explained by one court: A lead agency's “duty to condition project approval on incorporation of feasible mitigation measures only exists when such measures would [avoid or] ‘substantially lessen’ a significant environmental effect.” (San Franciscans for Reasonable Growth v. City and County of San Francisco (1989) 209 Cal.App.3d 1502, 1519.) “Thus, the agency need not, under CEQA, adopt every nickel and dime mitigation scheme brought to its attention or proposed in the project EIR.” (Ibid.) Rather, an EIR should focus on mitigation measures that are feasible, practical, and effective. (Napa Citizens for Honest Government v. Napa County Board of Supervisors (2001) 91 Cal.App.4th 342, 365.).

The GHG analysis determined Project impacts to be less than significant and no mitigation measures are warranted.

In addition, many of the Project’s sustainable design features reflect compliance with City code requirements and building standards (e.g., City’s Water-Efficient Landscape and Irrigation Standards), which must be implemented and complied with during Project construction activities and long-term operation. The comment does not provide new information that would require revisions to the Final EIR.

Comment 1-13:

The comment is summarized to state, the commenter claims the Final EIR relies on incorrect information to address the presence of suitable habitat for sensitive species or special-status species resulting in an incorrect baseline to evaluate impacts to biological resources. The comment goes on to cite numerous databases containing information on the presence of protected species.

Response to Comment 1-13:

The Project site is developed and located within a highly urbanized area in the City and includes ornamental trees, shrubs, and lawns. The nearest open space areas within two miles are cemeteries, a golf course, and the wellmaintained Santa Monica Beach. In general, suitable habitat for sensitive species, or special-status species, does not occur within the City. Terrestrial natural open space in the region is limited to the Santa Monica Mountains two miles north of the Project site and the Ballona wetlands five miles to the south. The analysis of impacts to biological resources was addressed in the Initial Study (FEIR Appendix A) and all impacts were determined to be less than significant. As discussed on page 16 of the Initial Study, within the City there is a limited number of threatened or endangered species that are likely to occur (City of Santa Monica 2010). These protected species are primarily found in marine environments, coastal habitats, and canyon areas. The Project site is located in a developed, urbanized area where there is no suitable foraging or nesting habitat to support any sensitive species. The project site is not located in riparian habitat or a sensitive natural community and does not support any aquatic resources regulated by the U.S. Army Corps of Engineers or California Department of Fish and Wildlife as jurisdictional wetlands, waters of the United States, or waters of the state (City of Santa Monica 2010).

As indicated in the Initial Study, the Project site is developed with ornamental trees near the 7-unit and 3-unit buildings, shrubs, planters, and plants near the Funeral Home building, and a grassy area near the corner of 20th Street and Arizona Avenue. Off-site street trees are located along 20th Street and Arizona Avenue. The Project site is surrounded by a church/school; mix of multi-family residential uses and commercial uses; residential buildings and medical/healthcare related buildings; and single-family and multi-family residential buildings. The Project site is within the City’s Healthcare Mixed Use District that includes the Santa Monica-UCLA Medical Center, Providence Saint John’s Health Center, and the areas immediately around and between these facilities. The Project site and surrounding areas have been developed, and the natural vegetation, soils, and hydrology have been removed. As such, the Final EIR’s determination that the area is urbanized is correct.

The California Department of Fish and Wildlife’s (CDFW) California Natural Diversity Database (CNDDB) is used to track special-status plant and wildlife species (CDFW 2022). CNDDB staff work with partners to maintain current lists of rare species, as well as to maintain an ever-growing database of GIS-mapped locations for these species.

Typically, the records in the CNDDB are of breeding occurrences for wildlife or populations for plants submitted by biologists. The loss of habitat due to development is the primary reason why most species become protected as defined by a special-status designation. There are some special-status species that have adapted to breeding and foraging in urban environments, for example American peregrine falcon (Falco peregrinus anatum), but most special-status species are associated with natural habitats. Most of the special-status species with recorded occurrences within the urbanized Los Angeles Basin are assumed to be extinct due to the loss of their associated habitats.

The eBird and iNaturalist databases, noted by the commenter, are open to the public and document an occurrence of a wildlife species at one instance but it may not establish the presence of suitable breeding and foraging habitat that a species is dependent upon. For example, a rare bird seen in a tree of a parking lot can be documented and submitted to these online geodatabases, but that species may only use riparian habitat for breeding. Therefore, a single, transient occurrence of a special-status bird can occur anywhere, but that does not establish suitable habitat or territory at the location. Just that the location is within the range of the species, which includes areas that the species is transient in during migration.

Most of the special-status species with recorded occurrences within the urbanized Los Angeles Basin are assumed to be extinct due to the loss of their associated habitats. Of the 18 CNDDB records within one mile of the Project site, 10 are either extinct or possibly extirpated (needs field truthing) (CDFW 2022). Of the eight extant records, five were recorded more than 70 years ago and lack the information for accurate mapping. The remaining three extant records are two monarch butterfly species (Danaus plexippus pop. 1) and one is silver-haired bat (Lasionycteris noctivagans). The Project site lacks tree groves that wintering monarch could use for winter roosts and the lower montane coniferous forest and old-growth riparian forests that silver-haired bats use for roosting.

The biological survey of the Project site, conducted by the commenter’s biologist, Dr. Smallwood (see Exhibit B) occurred during the fall migration season. Based on the survey, the Project site and the surrounding vicinity provides minimal roosting and foraging habitat for any sensitive or protected special-status species. For example, the California gull (Larus californicus) and red-tailed hawk (Buteo jamaicensis) have wide ranges and are transient over many areas; however, the Project site and surrounding areas do not provide typical foraging and nesting habitat, unless the gull was observed eating trash discarded by humans. Most of the bird species observed by Dr. Smallwood are common urban adapted species. The existing bird use of the site is not expected to change since the Project would replace existing an existing developed area with new development, and the Project would still be located in a highly urbanized area with minimal habitat for biological resources. This comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-14:

The comment is summarized to state that the aerosphere (airspace) above the Project, and its use by plant and wildlife species, was not take into consideration in the Final EIR. Specifically, how it the Project’s proposed buildings could impact birds due to bird-window collision.

Response to Comment 1-14:

As discussed previously, the approximately one-acre Project site is currently developed with three two-story buildings that house a restaurant and office space, and surrounding surface parking lots. The site is located within a highly urbanized area of the City surrounded by a mix of commercial uses, multi-story residential buildings, medical/healthcare buildings, a school, and a church. In urban areas, especially in areas with tall buildings bird collisions with windows and other man-made structures resulting in injury and mortality is a common occurrence.

Rates of bird-building collisions are influenced by many factors that interact across multiple spatial and temporal scales. At small scales, collisions are influenced by features of buildings (e.g., size, height, and window/glass area) and their immediate surroundings (e.g., nearby vegetation and greenspace). Bird-window collision mortality has been shown to be strongly associated with an interaction effect between building size and regional urbanization, with the positive effect of building size on mortality strongest in areas with low levels of regional urbanization and weak to nonexistent in regions with high levels of urbanization (Loss et al. 2019, Hager et al. 2013). Collision mortality was consistently low for small buildings, regardless of large-scale urbanization (Hager et al. 2017).

The proposed Project includes development of a new 3-story building and re-use of a portion of one of the existing buildings. The Project would not constitute a substantive change to the surrounding urban environment increasing the risk of collisions because the site is already developed with multi-story buildings and the surrounding area is densely developed with buildings that range in height. The Project would also be required to comply with the City’s Municipal Code Section 9.21.120 which prohibits the use of highly reflective building materials. Section 9.21.120 (D)(3) states that no more than 25% of the surface area of any façade on any new building or addition to an existing building shall contain black or mirrored glass or other mirror-like material that is highly reflective.

The bird collision rate stated in this comment is speculative and not supported by substantial evidence that such bird mortalities would occur due to construction of a 3-story building at the Project site. Furthermore, given the urbanized nature of the Project area and the significant number, density and height of existing buildings, construction of a 3-story building would not be expected to change flying patterns of bird species in the area such

that there would an increase in bird window collisions. This comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-15:

To summarize the comment, the commenter alleges the Final EIR failed to analyze cumulative effects on wildlife because it incorrectly assumed lack of suitable habitat for protected species on the Project site and is requesting an analysis of the Project’s potential impacts to bird mortality and its contribution to cumulative impacts of bird-window collision mortality in the City. The commenter goes on to state the City should address these concerns through development of a City ordinance designed to guide building design, fatality monitoring, and compensatory mitigation for loss of birds.

Response to Comment 1-15:

Records of bird mortality due to collisions with windows or buildings is not currently tracked by any state or local agency; therefore, it is too speculative to evaluate cumulative impacts to protected bird species that are killed colliding with windows or buildings in the City. The comment is not supported by substantial evidence that bird mortalities of protected species constitute a significant impact. Potential impacts to biological resources was addressed in the Initial Study (FEIR Appendix A). The Initial Study determined that the proposed Project would not have any potential to result in a significant impact to biological resources and the topic was eliminated from further consideration in the EIR. As stated on page 16 of the Initial Study, in general, suitable habitat for sensitive species, or special-status species, does not occur within the City. The Project site is fully developed and does not extend into undisturbed areas. The development of a new building in place of an existing parking lot would not result in the taking of rare or sensitive species or the degradation of sensitive habitat. Therefore, potential impacts to the habitat and range of known sensitive species in the area are not significant and do not warrant additional evaluation.

Please see also the discussion above under Response to Comment 1-13 and Response to Comment 1-14.

Further, the Project site is developed and located within a highly urbanized area that has been in that condition for at least 100 hundred years based off a review of historical topographic maps. Species expected to use the Project site and the surrounding area from the present to the foreseeable future are expected to be urban adapted or transient since the Project does not remove existing habitat because it does not exist, the Project would not change the urban nature of the site or surroundings. Therefore, because the Project would not remove any habitat that could support protected terrestrial or avian wildlife species, the Project would not contribute to the cumulative decline of any protected species. A cumulative analysis of avian mortality due to collisions with windows or buildings is not warranted for common bird species. This comment does not establish any new information that would require revisions to the Final EIR.

To summarize the comment, it is the opinion of the commenter that the EIR is inadequate and urges the City to not recommend certification of the Final EIR or approval of the Project in order to allow staff additional time to address their concerns.

Please see also Responses to Comments 1-19 through 1-24, below, that provide further evidence that these issues were adequately evaluated in the Final EIR.

Comment 1-19:

In summary, the comment reiterates that there is not adequate evidence for the City to reject Alternative 4 because it does not meet all the objectives of the Project, specifically the objective for the Project to provide employment, economic, and fiscal benefits.

Response to Comment 1-19:

Please see Response to Comment 1-2. As detailed in that response, Alternative 4 would generally meet most of the objectives identified for the Project and would reduce the severity of Project impacts. However, this alternative would not generate local tax revenue, provide new construction jobs, or house new residents to the same degree as the Project and therefore would not meet the Employment, Economic, and Fiscal Benefits objective as well as the Project. This Alternative is proposing a Project that is approximately 39,000 sf smaller when compared to the proposed Project. Although this alternative would generally meet most of the objectives identified for the Project and would reduce the severity of Project impacts it would generate less money in local property and sales tax because the building has a smaller footprint and would require fewer construction workers and employees to support local businesses. As noted in the Planning Commission staff report (dated November 3, 2021), “[A]lthough the proposed project does not include housing, the project satisfies other LUCE goals and policies prescribed for the HMU district.

As provided in the LUCE, the HMU (Healthcare Mixed Use District) land-use parameters include hospital and medical office uses, pharmacies, residential care, rehabilitation and outpatient clinics, affordable, workforce and marketrate housing targeted at hospital employees, and supportive retail uses. The proposed medical facility contributes to the range of land uses intended for the district.”
The City is required to prepare the Findings of Fact for those impacts that can be reduced to less than significant with mitigation and a Statement of Overriding Considerations for any significant and unavoidable impacts. The lead

agency must consider the Final EIR and the all the evidence in the record to determine if the overriding economic, legal, social, technological and other benefits of the Project outweigh the significant and unavoidable effects of the Project, including alternatives. Absent any significant and unavoidable impacts it is up to the discretion of the City Council, as lead agency, after review of all the evidence in the record to make the final determination to approve the Project or a Project alternative. The Courts have confirmed that “a public agency may find that an alternative is ‘infeasible’ if it determines, based upon the balancing of the statutory factors, that an alternative cannot meet project objectives or ‘is impractical or undesirable from a policy standpoint.’” (Los Angeles Conservancy v. City of West Hollywood (2017)).

Comment 1-20:

The commenter reiterates “the FEIR’s air model . . .artificially reduced the Project’s construction and operational emissions.” In summary, “the FEIR’s unsubstantiated input parameters for emissions, which led to an improper analysis of the Project’s air quality impacts.”
Response to Comment 1-20:

Please see Responses to Comments 1-4 and 1-5. As discussed in those responses, changes to the default CalEEMod assumptions for Project emissions modeling were appropriate and based on input from the Project applicant and Project-specific information. Specifically, the model was updated based on the total site acreage presented in Chapter 3.0, Project Description, which includes 1.03 acres that would be subject to grading/shoring activities during Project construction. Furthermore, the off-road construction equipment was adjustment based on Project-specific information provided by the Project applicant, as described on page 4.2-32 in the Air Quality section of the Final EIR. The number of worker vehicle, vendor truck, and haul truck trips were adjusted also based on Project-specific information. For demolition haul trips, the Project would involve the demolition of three buildings and a surface parking lot. CalRecycle’s Construction/Demolition and Inert Debris Tools and Resources rate of 2,400 pounds per cubic yard of debris for asphalt was used to estimate the number of haul trips from removal of asphalt debris while CalEEMod was used to estimate the haul trips associated with demolition of the existing buildings.

Therefore, the overall number of haul trips resulting from construction of the Project was based on the building square footage and the approximate tonnage of asphalt debris, which was estimated to be 164 one-way haul truck trips. Worker and vendor trips were conservatively rounded up based on CalEEMod default data and Project specific information. There are duplicate phases (i.e., grading 2 and building construction 2 and 3) assumed in the modeling in order to capture durations for specific construction equipment. Because those additional phases would be part of the overall main grading and building construction subphases, the worker vehicle, vendor truck, and haul truck trips are included in the main grading and building construction subphases and were zeroed out for those specific subphases (grading 2 and building construction 2 and 3) to avoid double-counting of trips. As such, the use and update of CalEEMod default parameters is appropriate and the Final EIR’s analysis is adequate as presented and does not “artificially reduced the Project’s construction and operational emissions” as stated in the comment.

Comment 1-21:

To summarize, the commenter reiterates that the Project’s HRA is required to evaluate construction and operation of the Project together and requests the email from the SCAQMD correcting this assumption was not provided; therefore, it could not be verified.

Response to Comment 1-21:

Please see Responses to Comments 1-7 and 1-9. As previously discussed, the commenter inappropriately sums their estimated cancer risk associated with construction and operational activities and does not provide reference to guidance from the regional or state air quality expert agencies to support their approach. Neither the SCAQMD nor OEHHA provides guidance requiring that construction and operational health risk be evaluated together. Based on an email from Michael Krause, Planning and Rule Manager with SCAQMD, a project’s construction and

MEMORANDUM

operational health risks need to be evaluated separately (Krause 2019). The personal communication email between M. Krause (SCAQMD) and A. Poll (Dudek) is provided as an attachment to this memorandum. Furthermore, an operational HRA would not be required as the Project would not result in a long-term source of TAC emissions and does not include any of the land uses described in CARB’s Air Quality and Land Use Handbook. Thus, the Project’s construction HRA is analyzed in accordance with industry guidance and no changes to the Final EIR are required.

Comment 1-22:

The comment states “the FEIR and RTC still did not consider performance-based standards under CARB’s 2017 Scoping Plan.” Additionally, “the RTC fails to adjust the FEIR’s analysis with regard to consistency with SCAG’s RTP/SCS, and the GHG analysis therefore remains inadequate”.

Response to Comment 1-22:

Please see Response to Comment 1-11. As previously discussed, a lead agency has the discretion to determine, in the context of a particular project, whether to: (1) use a model or methodology to quantify GHG emissions resulting from a project, and which model or methodology to use; or (2) rely on a qualitative analysis or performance-based standards. The City appropriately applied their discretion in providing a qualitative GHG emissions CEQA analysis.

The quantitative GHG emissions estimates for the Project were provided for informational purposes only and were not used to determine significance because neither CARB, SCAQMD, nor the City has adopted quantitative projectlevel significance thresholds for assessing impacts related to GHG emissions applicable to the Project. Thus, Project significance is based solely on the analysis of the Project’s consistency with applicable regulatory plans and policies to reduce GHG emissions, as discussed on page 4.6-35 of the Final EIR. The commenter also inappropriately provides a comparison of the Project’s buildout emissions from 2024 and compares the emissions to the 2017 Scoping Plan’s efficiency target of 2035. As the Project would be build out in the near term, a comparison with the 2035 per capita efficiency target is inappropriate. The main sources of GHG emissions from land use projects would be from energy and mobile sources. Substantial improvements to the vehicular fleet mix and compliance with Senate Bill 100 requirements to procure electricity from renewable sources would further decrease the Project’s emissions. The evaluation of the Project’s GHG emissions is analyzed adequately contrary to the commenter’s assertion. Therefore, this comment does not establish any new information that would require revisions to the Final EIR.

Comment 1-23:

The comment is referring to biological resources and claims the “City mischaracterized the importance of the presence of these species (this is in reference to species identified by the commenter’s biologist, noted in Response to Comment 1-13), writing them off as transient and therefore insignificant.” The comment goes on to state “the City’s explanation relied on pseudoscientific characterizations of wildlife habitat, and that species occurring in the City were using urbanized Santa Monica for survival.” Response to Comment 1-23:

Please see Response to Comment 1-13. As detailed in that response, most of the wildlife observed are common to urban environments and adapted to human activity. The City values wildlife, contrary to the commenter’s assertion that the City perceives wildlife that may use the habitat on the site as only “transient” and “consumers of human garbage”. However, to be clear the Project site is located in a developed, urban area of the City and does not provide quality native foraging or nesting habitat. The two species identified in the comment that are designated as special status are California gull and Red-tailed hawk. California gull is no longer designated as a special-status species

but is on California Department of Fish and Wildlife’s (CDFWs) Watch List1. The following is its life history account from CDFW: “A fairly common nester at alkali and freshwater lakes and ponds east of the Sierra Nevada and Cascade ranges... In late summer the species migrates westward across the Sierra Nevada from interior nesting grounds to winter in California and the Pacific Northwest... Preferred habitats along the coast are sandy beaches, mudflats, rocky intertidal, and pelagic areas of marine and estuarine habitats, as well as fresh and saline emergent wetlands... Inland, frequents lacustrine, riverine, and cropland habitats, landfill dumps, and open lawns in cities...

In winter, this omnivore feeds on garbage, carrion, earthworms, adult insects, and larvae. It frequents landfill dumps, fields, and pastures… (Zeiner et al. 1990).” Nesting habitat for the species is not present on the Project site. This species has a wide range during the non-breeding season and may forage on garbage within the Project area and could also use the small lawn along Arizona Avenue for foraging; however, this is considered low quality habitat. The proposed Project would not change the current opportunities for the species to forage within the Project area; therefore, potential impacts to the species are not significant and do not warrant additional evaluation.

Red-tailed hawk is not listed by any agency but is protected under the Migratory Bird Treaty Act and California Fish and Game Code. The following is its life history account from CDFW: “Common, permanent breeding and winter resident and migrant. Breeds throughout California, and winters in all areas without heavy snow cover… Eats small mammals up to hares in size, small birds, reptiles, amphibians, and some carrion… Feeds in grasslands and grass/shrub stages of most habitats. Roosts in trees… Usually nests in large trees near openings, in older, mature forests, especially riparian deciduous habitats… Sometimes nests in isolated trees, or in small groves in open habitat” (Zeiner et al. 1990). Nesting habitat for the species is not present on the Project site; however, this species has a wide foraging range that may include the larger Project vicinity. The developed nature and small size of the Project site provides limited foraging opportunities due the lack of open habitats and natural grasslands. The Project would not change the current opportunities for the species within the area; therefore, potential impacts to the species are not significant and do not warrant additional evaluation.

Comment 1-24:

To summarize, the commenter refers to occurrences of species identified in eBird and iNaturalist databases and reiterates that additional study is needed to determine if these species use the site for nesting, foraging or as an important stopover during migration and the commenter’s biologist cites to evidence that the Project may adversely affect special-status species.

Response to Comment 1-24:

Please see Responses to Comments 1-13 and 1-23. California gull and Red-tailed hawk are not expected to nest in the Project area due to absence of their associated breeding habitats. Other common bird species may use the site for nesting and foraging but these species are not considered special-status and have adapted to living in a developed, urban environment. The proposed Project would not change the current opportunities for foraging or use as a stopover since the Project is replacing an existing developed site with new development, essentially not introducing new land uses that would alter the ability of these species to continue using the site. Additionally, common, urban-adapted wildlife are not expected to be affected due the consistency of the existing conditions preand post-project construction. Therefore, potential impacts to wildlife are not significant and do not warrant additional evaluation.

Comment 1-25:

The comment reiterates the Project could impact bird species due to collisions with building windows. To summarize, the comment states building height “is not determinative of its impact on birds, and further study is required by the City to assess the way in which birds move through the area…” and that reflective windows allowed 1 CDFW maintains a list consisting of taxa that were previously designated as "Species of Special Concern" (SSC) but no longer merit that status, or which do not yet meet SSC criteria, but for which there is concern and a need for additional information to clarify status.

under the City’s Municipal Code could result in bird collisions, as identified in scientific studies addressing this issue.

Response to Comment 1-25:

Please see Responses to Comments 1-14 and 1-15. The comment does not address the surrounding conditions of the Project site, which includes urban development, surface parking lots, roadways, and overhead electrical lines.

As stated on pages 3-2 and 3-3 in Chapter 3.0, Project Description, the Project site is surrounded by buildings that range from one- to multistory buildings up to six stories within a highly developed area of the City. It is acknowledged that birds currently use the Project site, with the majority being resident, common urban-adapted birds or birds that may use the Project site for short periods during its life history (i.e., foraging or migrating). The proposed Project replaces existing development (including trees), with development and landscaping, including new trees, so birds are expected to continue to use the site in the same capacity post-construction. Scientific studies have documented that all buildings are capable of impacting birds due to bird window collisions, including residences, office buildings, overhead electrical lines, etc. (Loss et al. 2014). In a developed, urban setting most buildings include windows or there are other obstacles that could affect birds, as mentioned previously; however, the Project’s increase in potential window surface area beyond existing conditions (two 2-story buildings), and due to its location in a highly developed area, would not be expected to substantially increase bird-window collisions relative to existing conditions (Loss et al. 2019, Hager et al. 2013). Therefore, potential impacts to birds due bird-window collisions are not significant and do not warrant additional evaluation.

Comment 1-26:

To summarize the comment, it is the opinion of the commenter that the EIR is inadequate and urges the City to not recommend certification of the Final EIR or approval of the Project in order to allow staff additional time to address their concerns in a revised EIR.

Response to Comment 1-26:

The commenter’s opinion is noted and forwarded to the decision makers for consideration. The responses provided to this letter address all of the concerns regarding the adequacy of the Final EIR raised by the commenter and preparation of a revised EIR is not required.

Re: Comment on Final Environmental Impact Report, 1242 20th Street Wellness Center (SCH 2018011001)
Dear Commissioner Landres, Honorable Members of the Planning Commission, Ms.

Kwok, Ms. Yeo and Ms. Anderson-Warren:

I am writing on behalf of Supporters Alliance for Environmental Responsibility (“SAFER”), regarding the Final Environmental Impact Report; (“FEIR”) prepared for the Project known as 1242 20th Street Wellness Center (SCH #2018011001), including all actions referring or related to the development of approximately 73,555 square feet (sf) of medical research and development (R&D) and clinical/medical office space with five levels of subterranean parking located at 1925 Arizona Avenue and 1242 20th Street, on APNs 4276-013-033 and 4276-013-032 in the City of Santa Monica (“Project”).

After reviewing the FEIR, we conclude that the FEIR fails as an informational document, fails to adequately analyze the Project’s environmental impacts, and fails to impose all feasible mitigation measures to reduce the Project’s impacts. SAFER November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

requests that the Community Development Department address these shortcomings in a revised environmental impact report (“REIR”) and recirculate the REIR prior to considering approvals for the Project.

This comment has been prepared with the assistance of Certified Industrial Hygienist, Francis “Bud” Offermann, PE, CIH (Exhibit A), environmental consulting firm Soil/Water/Air Protection Enterprise (“SWAPE”) (Exhibit B), and expert wildlife biologist Dr. Shawn Smallwood (Exhibit C). We incorporate the Offermann, SWAPE, and Smallwood comments herein by reference.

I. Project Description.

The applicant is proposing to demolish a 4-car garage, two two-story structures, and a surface parking lot to develop a 73,555 square foot medical research and development and clinical/medical office space within a “Wellness Center” located at 1925 Arizona Avenue and 1242 20th Street in the City of Santa Monica. This would include construction of a 3-story building and construction of “support areas” including terraces and utility support/elevator spaces, and five levels of subterranean parking.

The parking garage would include 275 parking spaces and a mix of operational and storage spaces for R&D uses, trash and recycling rooms, bicycle parking and storage, EV charging spaces, employee locker and shower facilities, and maintenance functions.

II. Legal Background.

CEQA requires that an agency analyze the potential environmental impacts of its proposed actions in an environmental impact report (“EIR”) (except in certain limited circumstances). See, e.g. Pub. Res. Code § 21100. The EIR is the very heart of CEQA.

Dunn-Edwards v. BAAQMD (1992) 9 Cal.App.4th 644, 652. “The ‘foremost principle’ in interpreting CEQA is that the Legislature intended the act to be read so as to afford the fullest possible protection to the environment within the reasonable scope of the statutory language.” Communities for a Better Environment v. Calif. Resources Agency (2002) 103 Cal. App. 4th 98, 109.

CEQA has two primary purposes. First, CEQA is designed to inform decision makers and the public about the potential, significant environmental effects of a project. 14 Cal. Code Regs. (“CEQA Guidelines”) § 15002(a)(1). “Its purpose is to inform the public and its responsible officials of the environmental consequences of their decisions before they are made. Thus, the EIR ‘protects not only the environment but also informed self-government.’” Citizens of Goleta Valley v. Board of Supervisors (1990) 52 Cal.3d 553, 564. The EIR has been described as “an environmental ‘alarm bell’ whose purpose it is to alert the public and its responsible officials to environmental changes before they have reached ecological points of no return.” Berkeley Keep Jets Over the November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

Bay v. Bd. of Port Comm’rs. (2001) 91 Cal. App. 4th 1344, 1354 (“Berkeley Jets”); County of Inyo v. Yorty (1973) 32 Cal.App.3d 795, 810.

Second, CEQA requires public agencies to avoid or reduce environmental damage when “feasible” by requiring “environmentally superior” alternatives and all feasible mitigation measures. CEQA Guidelines § 15002(a)(2) and (3); see also, Berkeley Jets, 91 Cal.App.4th at pp. 1344, 1354; Citizens of Goleta Valley, 52 Cal.3d at 564. The EIR serves to provide agencies and the public with information about the environmental impacts of a proposed project and to “identify ways that environmental damage can be avoided or significantly reduced.” CEQA Guidelines §15002(a)(2). If the project will have a significant effect on the environment, the agency may approve the project only if it finds that it has “eliminated or substantially lessened all significant effects on the environment where feasible” and that any unavoidable significant effects on the environment are “acceptable due to overriding concerns.” Pub. Res. Code § 21081; 14 Cal.Code Regs. § 15092(b)(2)(A) & (B). The lead agency may deem a particular impact to be insignificant only if it produces rigorous analysis and concrete substantial evidence justifying the finding. Kings County Farm Bureau v. City of Hanford (1990) 221 Cal.App.3d 692, 732.

While the courts review an EIR using an “abuse of discretion” standard, “the reviewing court is not to ‘uncritically rely on every study or analysis presented by a project proponent in support of its position. A ‘clearly inadequate or unsupported study is entitled to no judicial deference.’” Berkeley Jets, 91 Cal. App. 4th at p. 1355 (emphasis added) (quoting Laurel Heights Improvement Assn. v. Regents of University of California (1988) 47 Cal. 3d 376, 391 409, fn. 12). As the court stated in Berkeley Jets:

A prejudicial abuse of discretion occurs “if the failure to include relevant information precludes informed decisionmaking and informed public participation, thereby thwarting the statutory goals of the EIR process.” (San Joaquin Raptor/Wildlife Rescue Center v. County of Stanislaus (1994) 27 Cal.App.4th 713, 722; Galante Vineyards v. Monterey Peninsula Water Management Dist. (1997) 60 Cal. App. 4th 1109, 1117; County of Amador v. El Dorado County Water Agency (1999) 76 Cal. App. 4th 931, 946.) More recently, the California Supreme Court has emphasized that:

When reviewing whether a discussion is sufficient to satisfy CEQA, a court must be satisfied that the EIR (1) includes sufficient detail to enable those who did not participate in its preparation to understand and to consider meaningfully the issues the proposed project raises [citation omitted], and (2) makes a reasonable effort to substantively connect a project's air quality impacts to likely health consequences.

Sierra Club v. Cty. of Fresno (2018) 6 Cal.5th 502, 510 (2018), citing Laurel Heights Improvement Assn. v. Regents of University of California (1988) 47 Cal.3d 376, 405.

November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

“Whether or not the alleged inadequacy is the complete omission of a required discussion or a patently inadequate one-paragraph discussion devoid of analysis, the reviewing court must decide whether the EIR serves its purpose as an informational document.” Sierra Club v. Cty. of Fresno, 6 Cal.5th at 516. Although an agency has discretion to decide the manner of discussing potentially significant effects in an EIR, “a reviewing court must determine whether the discussion of a potentially significant effect is sufficient or insufficient, i.e., whether the EIR comports with its intended function of including ‘detail sufficient to enable those who did not participate in its preparation to understand and to consider meaningfully the issues raised by the proposed project.’” 6 Cal.5th at 516, citing Bakersfield Citizens for Local Control v. City of Bakersfield (2004) 124 Cal.App.4th 1184, 1197. “The determination whether a discussion is sufficient is not solely a matter of discerning whether there is substantial evidence to support the agency’s factual conclusions.” 6 Cal.5th at 516. Whether a discussion of a potential impact is sufficient “presents a mixed question of law and fact. As such, it is generally subject to independent review. However, underlying factual determinations—including, for example, an agency’s decision as to which methodologies to employ for analyzing an environmental effect—may warrant deference.” Sierra Club v. Cty. of Fresno, 6 Cal.5th at 516. As the Court emphasized:
[W]hether a description of an environmental impact is insufficient because it lacks analysis or omits the magnitude of the impact is not a substantial evidence question. A conclusory discussion of an environmental impact that an EIR deems significant can be determined by a court to be inadequate as an informational document without reference to substantial evidence.

Sierra Club v. Cty. of Fresno, 6 Cal.5th at 514. We find that the FEIR prepared by the City here is inadequate for the reasons set forth below.

III. DISCUSSION
A. The FEIR Fails to Provide Comparative Data to Support Its Rejection of one of the Project Alternatives.

An EIR must describe a range of reasonable alternatives to the Project, or to the location of the Project, which would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project, and evaluate the comparative merits of the alternatives. Section 15126.6(b) of the CEQA Guidelines states:

Because an EIR must identify ways to mitigate or avoid the significant effects that a project may have on the environment, the discussion of alternatives shall focus on alternatives to the project or its location which are capable of avoiding or November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

substantially lessening any significant effects of the project, even if these alternatives would impede to some degree the attainment of project objectives, or would be more costly.

One of CEQA’s fundamental requirements is that the DEIR must identify the “environmentally superior alternative,” and require implementation of that alternative unless it is infeasible. 14 Cal.Code Regs. §1526.6(e)(2); Kostka & Zischke, Practice Under the California Environmental Quality Act §15.37 (Cont. Educ. Of the Bar, 2008).

As explained by the Supreme Court, an environmentally superior alternative may not be rejected simply because it is more expensive or less profitable:

The fact that an alternative may be more expensive or less profitable is not sufficient to show that the alternative is financially infeasible. What is required is evidence that the additional costs or lost profitability are sufficiently severe as to render it impractical to proceed with the project.

Citizens of Goleta Valley v. Bd. of Supervisors (1988) 197 Cal.App.3d 1167, 1180-81; see also, Burger v. County of Mendocino (1975) 45 Cal.App.3d 322 (county’s approval of 80 unit hotel over smaller 64 unit alternative was not supported by substantial evidence).

The FEIR’s conclusion that Alternative 4 is infeasible simply because it does not meet economic objectives falls short of CEQA requirements. In Save Round Valley Alliance v. County of Inyo, the County asserted three reasons in its FEIR for its rejection of an environmentally superior alternative. Relevant here, one of the reasons was that the project proponent “could not expect to achieve the same economic objectives” with the alternative. (2007) 157 Cal.App.4th 1437, 1459. The Court found that this explanation fell short of CEQA requirements because it reflected a “misunderstanding regarding the economic feasibility of an alternative.” Id. at 1461. The Court went on to state:

Although the “economic viability” of an alternative is a relevant consideration in evaluating the feasibility of the alternative (see Guidelines, § 15126.6, subd. (f)(1)), the fact that Walters cannot achieve the same economic objective from developing the BLM property is not determinative. The issue is not whether the alternative is less profitable than the project as proposed, but whether the reduced profitability of the alternative is “‘sufficiently severe as to render it impractical to proceed with the project.’ []”
Id. Further, the Court stated that “there is no evidence or analysis whatsoever of the comparative costs or profitability of developing the two parcels.” Id. at 1462. The EIR “include[d] only the barest of facts regarding the BLM parcel, vague and unsupported conclusions about aesthetics, views, and economic objectives, and no independent November 3, 2021

1242 20th Street Wellness Center (SCH 2018011001)

analysis whatsoever of relevant considerations. In this respect, the County failed to proceed in the manner required by law.” Id. at 1465.

Here, the FEIR states only that Alternative 4 “would not fully meet the economic objectives of the proposed project.” FEIR, p. 6-55. Under the standard set forth by Save Round Valley, this is an inadequate analysis of the alternative, and does not constitute substantial evidence that Alternative 4 is infeasible.

B. There is Substantial Evidence that the Project Will Have a Significant Health Risk Impact from its Indoor Air Quality Impacts.

Certified Industrial Hygienist, Francis “Bud” Offermann, PE, CIH, has conducted a review of the proposed Project and relevant documents regarding the Project’s indoor air emissions. Indoor Environmental Engineering Comments (October 14, 2021) (Exhibit A). Mr. Offermann concludes that it is likely that the Project will expose commercial employees of the Project to significant impacts related to indoor air quality, and in particular, emissions of the cancer-causing chemical formaldehyde. Mr. Offermann is a leading expert on indoor air quality and has published extensively on the topic. Mr.

Offermann’s expert comments and curriculum vitae are attached as Exhibit A.

Mr. Offermann explains that many composite wood products used in building materials and furnishings commonly found in offices, warehouses, residences, and hotels contain formaldehyde-based glues which off-gas formaldehyde over a very long time period. He states, “[t]he primary source of formaldehyde indoors is composite wood products manufactured with urea-formaldehyde resins, such as plywood, medium density fiberboard, and particleboard. These materials are commonly used in building construction for flooring, cabinetry, baseboards, window shades, interior doors, and window and door trims.” Ex. A, p. 2-3.

Formaldehyde is a known human carcinogen. Mr. Offermann states that future commercial employees of the Project would be exposed to a 17.7 in one million risk, assuming all materials are compliant with the California Air Resources Board’s formaldehyde airborne toxics control measure. Id. at 4. This potential exposure level exceeds the South Coast Air Quality Management District’s (“SCAQMD”) CEQA significance threshold for airborne cancer risk of 10 per million. Id.

Mr. Offermann concludes that these significant environmental impacts should be analyzed in the EIR and mitigation measures should be imposed to reduce the risk of formaldehyde exposure. Id. Mr. Offermann identifies mitigation measures that are available to reduce these significant health risks, including the installation of air filters and a requirement that the applicant use only composite wood materials (e.g. hardwood plywood, medium density fiberboard, particleboard) for all interior finish systems that are made with CARB approved no-added formaldehyde (NAF) resins or ultra-low emitting formaldehyde (ULEF) resins in the buildings’ interiors. Id. at 11.

The City has a duty to investigate issues relating to a project’s potential environmental impacts, especially those issues raised by an expert’s comments. See Cty. Sanitation Dist. No. 2 v. Cty. of Kern, (2005) 127 Cal.App.4th 1544, 1597–98 (“under CEQA, the lead agency bears a burden to investigate potential environmental impacts”). In addition to assessing the Project’s potential health impacts to employees, Mr. Offermann identifies the investigatory path that the City should be following in developing an EIR to more precisely evaluate the Project’s future formaldehyde emissions and establishing mitigation measures that reduce the cancer risk below the BAAQMD level. Id. at 5-9. Such an analysis would be similar in form to the air quality modeling and traffic modeling typically conducted as part of a CEQA review.

The failure to address the project’s formaldehyde emissions is contrary to the California Supreme Court’s decision in California Building Industry Ass’n v. Bay Area Air Quality Mgmt. Dist. (2015) 62 Cal.4th 369, 386 (“CBIA”). At issue in CBIA was whether the Air District could enact CEQA guidelines that advised lead agencies that they must analyze the impacts of adjacent environmental conditions on a project. The Supreme Court held that CEQA does not generally require lead agencies to consider the environment’s effects on a project. CBIA, 62 Cal.4th at 800-801. However, to the extent a project may exacerbate existing adverse environmental conditions at or near a project site, those would still have to be considered pursuant to CEQA. Id. at 801 (“CEQA calls upon an agency to evaluate existing conditions in order to assess whether a project could exacerbate hazards that are already present”). In so holding, the Court expressly held that CEQA’s statutory language required lead agencies to disclose and analyze “impacts on a project’s users or residents that arise from the project’s effects on the environment.” Id. at 800 (emphasis added).

The carcinogenic formaldehyde emissions identified by Mr. Offermann are not an existing environmental condition. Those emissions to the air will be from the Project.

Commercial employees will be users of the Project. Rather than excusing the City from addressing the impacts of carcinogens emitted into the indoor air from the project, the Supreme Court in CBIA expressly finds that this type of effect by the project on the environment and a “project’s users” must be addressed in the CEQA process.

The Supreme Court’s reasoning is well-grounded in CEQA’s statutory language.

CEQA expressly includes a project’s effects on human beings as an effect on the environment that must be addressed in an environmental review. “Section 21083(b)(3)’s express language, for example, requires a finding of a ‘significant effect on the environment’ (§ 21083(b)) whenever the ‘environmental effects of a project will cause substantial adverse effects on human beings, either directly or indirectly.’” CBIA, 62 Cal.4th at 800 (emphasis in original). Likewise, “the Legislature has made clear—in declarations accompanying CEQA’s enactment—that public health and safety are of great importance in the statutory scheme.” Id., citing e.g., §§ 21000, subds. (b), (c), (d), (g), 21001, subds. (b), (d). It goes without saying that the future employees of the November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

Project are human beings and the health and safety of those workers is as important to CEQA’s safeguards as that of nearby residents currently living near the project site.

The City’s EIR must disclose and mitigate the potential environmental impacts to future users of the building.

C. There is Substantial Evidence that the Project Will Have Significant Adverse Air Quality, Health Risk, and Greenhouse Gas Impacts.

1. The FEIR Relied on Unsubstantiated Input Parameters to Estimate Project Emissions and Thus the Project May Result in Significant Air Quality Impacts.

Matt Hagemann, P.G., C.Hg., and Dr. Paul E. Rosenfeld, Ph.D., of the environmental consulting firm SWAPE reviewed the FEIR’s analysis of the Project’s impacts on air quality, health risk, and greenhouse gases. SWAPE’s comment letter and CVs are attached as Exhibit B and their comments are briefly summarized here.

SWAPE found that the FEIR incorrectly estimated the Project’s construction and operational emissions and therefore cannot be relied upon to determine the significance of the Project’s impacts on local and regional air quality. The FEIR relies on emissions calculated from the California Emissions Estimator Version CalEEMod.2016.3.2 (“CalEEMod”). FEIR, p. 4.2-30. This model, which is used to generate a project’s construction and operational emissions, relies on recommended default values based on site specific information related to a number of factors. Ex. B, p. 1. CEQA requires any changes to the default values to be justified by substantial evidence. Id. at 1-2.

SWAPE reviewed the FEIR’s CalEEMod output files and found that the values input into the model were inconsistent with information provided in the FEIR. Ex. B, p. 2.

As a result, the FEIR’s air quality analysis cannot be relied upon to determine the Project’s emissions.

Specifically, SWAPE found that the following values used in the FEIR’s air quality analysis were either inconsistent with information provided in the FEIR or otherwise unjustified:

1. Unsubstantiated Reduction to Acres of Grading Value. Ex. B, p. 2.

2. Unsubstantiated Off-Road Construction Equipment Usage Hours. Ex. B, p. 3.

3. Failure to Substantiate Demolition and Reduction to Number of Demolition Hauling Trips. Ex. B, p. 5.

4. Unsubstantiated Worker and Vendor Trip Numbers. Ex. B, p. 6.

5. Failure to Model Material Export. Ex. B, p. 8.

November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

As a result of these errors in the FEIR, the Project’s construction and operational emissions were underestimated and cannot be relied upon to determine the significance of the Project’s air quality impacts.

2. There is Substantial Evidence that the Project May Have a Significant Health Impact as a Result of Diesel Particulate Emissions.

One of the primary emissions of concern regarding health effects for land development projects is diesel particulate matter (“DPM”), which can be released during Project construction and operation. DPM consists of fine particles with a diameter less than 2.5 micrometers including a subgroup of ultrafine particles (with a diameter less than 0.1 micrometers). Diesel exhaust also contains a variety of harmful gases and cancer-causing substances. Exposure to DPM is a recognized health hazard, particularly to children whose lungs are still developing and the elderly who may have other serious health problems. According to the California Air Resources Board (“CARB”), DPM exposure may lead to the following adverse health effects: aggravated asthma; chronic bronchitis; increased respiratory and cardiovascular hospitalizations; decreased lung function in children; lung cancer; and premature deaths for those with heart or lung disease.1
The FEIR concluded that the mitigated excess cancer risk posed by the Project to nearby sensitive receptors would not exceed the SCAQMD significance threshold of 10 in one million, and that the Project would result in a less-than-significant operational health risk impact because of a low number of daily truck trips and compliance with CARB regulations. Ex. B, p. 9; FEIR, p. 4.2-48. SWAPE identifies four main reasons for why the FEIR’s evaluation of health risk impacts and less-than-significant conclusion is incorrect.

First, the FEIR’s construction HRA is incorrect due to the inputting of several incorrect values into the CalEEMod output files. Ex. B, p. 9. The FEIR’s HRA uses an underestimated DPM concentration, and therefore underestimates the Project’s cancer risk and cannot be relied upon to determine impacts of the Project. Id.

Second, because the FEIR did not prepare a quantified operational HRA, it fails to quantitively evaluate operational toxic air contaminants (“TACs”). Ex. B, p. 9. In failing to connect TAC emissions to potential health risks to nearby receptors, the Project fails to meet the CEQA requirement that projects correlate increases in project-generated emissions to adverse impacts on human health cause by those emissions. Ex. B, p. 10; See Sierra Club v. County of Fresno (2018) 6 Cal.5th 502, 510. 1 See CARB Resources - Overview: Diesel Exhaust & Health, available at https://ww2.arb.ca.gov/resources/overview-diesel-exhaust-and-health.).

Third, the California Department of Justice recommends the preparation of a quantitative HRA pursuant to the Office of Environmental Health Hazard Assessment (“OEHHA”), the organization responsible for providing guidance on conducting HRAs in California, as well as local air district guidelines. OEHHA released its most recent guidance document in 2015 describing which types of projects warrant preparation of an HRA. See “Risk Assessment Guidelines Guidance Manual for Preparation of Health Risk Assessments.” OEHHA, February 2015, available at:
http://oehha.ca.gov/air/hot_spots/hotspots2015.html. The OEHHA document recommends that if a project is expected to last over 6 months, the exposure should be evaluated throughout the project using a 30-year exposure duration to estimate individual cancer risks. Ex. B, p. 10. Based on its extensive experience, SWAPE reasonably assumes that the Project will last at least 30 years, and therefore recommends that health risk impacts from the project be evaluated. Id. A Revised EIR is therefore required to analyze these impacts.

Fourth, the FEIR fails to evaluate the “cumulative lifetime cancer risk to nearby, existing receptors as a result of Project construction and operation together.” Ex. B, p. 10 (emphasis in original). A Revised EIR should be prepared to quantify the cumulative excess cancer risk posed by the Project’s construction and operation to nearby, existing receptors, and compare it to the SCAQMD threshold of 10 in one million. Id.

SWAPE prepared a screening-level HRA to evaluate potential impacts from Project construction using AERSCREEN, a screening-level air quality dispersion model.

Ex. B, p. 11. SWAPE applied a sensitive receptor distance of 50 meters and analyzed impacts to individuals at different stages of life based on OEHHA and SCAQMD guidance utilizing age sensitivity factors. Id. at 11-14.

SWAPE found that the excess cancer risks at a sensitive receptor located approximately 50 meters away over the course of Project construction are approximately 12.5 in one million for infants and 69.1 in one million for children. Id. at

13. Moreover, the excess lifetime cancer risk over the course of Project construction and operation of 30 years is approximately 96.5 in one million. Id.

The risks to infants, children, and lifetime residents exceed SCAQMD’s threshold of 10 in one million.

SWAPE’s analysis constitutes substantial evidence that the Project may have a significant health impact as a result of diesel particulate emissions. SWAPE recommends that “an updated EIR [] be prepared and include an updated, quantified air pollution model as well as an updated, quantified refined HRA which adequately and accurately evaluates health risk impacts associate with both Project construction and operation.” Ex. B, p. 13-14.

3. The FEIR Failed to Adequately Analyze the Project’s Greenhouse Gas Impacts and Thus the Project May Result in Significant Greenhouse Gas Emissions.

The FEIR estimates that the Project would generate net annual GHG emissions of 1,147.12 metric tons of carbon dioxide equivalent per year (“MT CO2e/year”).

However, it does not compare those emissions to a threshold, instead relying on the Project’s consistency with CARB’s Climate Change Scoping Plan, SCAG’s 2020-2045 RTP/SCS, and the City of Santa Monica’s LUCE, Sustainable City Plan, Green Building and Energy Code, and Climate Action and Adaptation Plan. Ex. B, p. 14. However, SWAPE states that the FEIR’s conclusion about a less-than-significant greenhouse gas impact is incorrect for several reasons:
• The FEIR’s quantitative GHG analysis relies upon an incorrect and unsubstantiated air model;
• The FEIR’s unsubstantiated air model indicates a potentially significant impact;
• The FEIR fails to consider the performance-based standards under CARB’s Scoping Plan; and
• The FEIR fails to consider the performance-based standards under SCAG’s RTP/SCS.

SWAPE’s analysis demonstrates potentially significant health risk and GHG impacts from the project that necessitate mitigation, and it proposes that the Project’s sustainability design features be implemented as formal mitigation measures. In addition to implementing these measures, the Revised EIR should include an updated air quality, health risk, and GHG analysis.

D. The Project Will Have Significant Adverse Biological Impacts That the FEIR Fails to Adequately Analyze and Mitigate.

Shawn Smallwood, Ph.D. reviewed the FEIR’s analysis of the Project’s biological impacts. Dr. Smallwood’s comment letter and CV are attached as Exhibit C and his comments are briefly summarized here.

1. The FEIR is inadequate in its characterization of the existing environmental setting as it relates to wildlife.

Dr. Smallwood visited the site of the Project on October 18, 2021 and performed a reconnaissance level survey of wildlife utilizing the area of the Project. He was accompanied by Noriko Smallwood, a wildlife biologist with an M.S. degree from California State University Los Angeles. Ex. C, p. 1. Dr. Smallwood reconnoitered the area for 114 minutes. Id. During that visit, he observed the presence of 18 species of vertebrate wildlife at the Project site, two of which are special-status species. Id., see November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

Table 1, Ex. C, p. 2. Most of the species he observed relevant to the Project’s impacts were bird species. Id.

Every CEQA document must start from a “baseline” assumption. The CEQA “baseline” is the set of environmental conditions against which to compare a project’s anticipated impacts. Communities for a Better Envt. v. So. Coast Air Qual. Mgmt. Dist. (2010) 48 Cal. 4th 310, 321. Unfortunately, the FEIR proponents did not perform a survey for wildlife at the Project site because they claimed that suitable habitat for sensitive species or special-status species did not occur within the city. Ex. C at 6, DEIR at 5-7. Dr. Smallwood states that this erroneous conclusion is based on the FEIR’s incorrect determination that “(1) disturbance precludes the occurrence of special-status species, and (2) all special-status species depend solely on natural communities.” Ex. C at 6. Contrary to these incorrect assumptions, Dr. Smallwood explains that “many assignments of special status have been to species that occur only in California or whose geographic ranges are small or diminishing,” and “many special-status species occur in anthropogenic environments.” Id. A skewed baseline such as the one used by the City here ultimately “mislead(s) the public” by engendering inaccurate analyses of environmental impacts, mitigation measures and cumulative impacts for biological resources. See San Joaquin Raptor Rescue Center, 149 Cal.App.4th 645, 656; Woodward Park Homeowners, 150 Cal.App.4th 683, 708-711.

Dr. Smallwood notes that there are multiple databases that would have been useful to determine presence and likelihood of presence, such as eBird and iNaturalist.

Id. Dr. Smallwood reviewed these databases and found that the Project site “either occurs within the geographic ranges or [] occurs near where others have reported sightings of at least 67 special-status species of wildlife.” Id. at 6; see Table 2, Ex. C, p. 7-9. Of those species, 33 have been reportedly seen within 1 mile of the Project site. Id.

The occurrence of special-status species at or near the Project site warrants discussion and analysis in an EIR to ensure that any impacts are mitigated to a less than significant level.

In addition to this failure to fully assess species occurrences, Dr. Smallwood found that the FEIR also relied on the erroneous presumption that impacts to biological resources occurred only to terrestrial habitats, thus overlooking an entire category of species that rely primarily on the aerosphere. Ex. C, p. 6-7. The FEIR neglected to consider this portion of habitat, and as a result, no attention was paid to the impacts the Project will have on avian species from collisions with the building’s windows and other structures. A Revised EIR is necessary to consider the species present in the aerosphere at the Project site.

2. The FEIR fails to account for the increased possibility of birdwindow collision mortality that will be caused by the project.

According to Dr. Smallwood, the Project will most likely have a significant impact November 3, 2021
Comment on Final Environmental Impact Report
1242 20th Street Wellness Center (SCH 2018011001)

on birds as a result of window collisions. The City has not analyzed or mitigated these potential impacts to special-status birds.

Dr. Smallwood identifies the now widely-recognized impact of bird collisions with windows and other building structures:

Window collisions are often characterized as either the second or third largest source or human-caused bird mortality. The numbers behind these characterizations are often attributed to Klem’s (1990) and Dunn’s (1993) estimates of about 100 million to 1 billion bird fatalities in the USA, or more recently Loss et al.’s (2014) estimate of 365-988 million bird fatalities in the USA or Calvert et al.’s (2013) and Machtans et al.’s (2013) estimates of 22.4 million and 25 million bird fatalities in Canada, respectively . . .

Ex. C, p. 11. Dr. Smallwood’s site visit confirmed the presence of many bird species that would travel through the Project site’s air space. Id. He also notes that “many of the special-status species in Table 2 [of his comment] have been documented as window collision fatalities and are therefore susceptible to new structural glass installations.” Id.

In an effort to assess the scope of the Project’s impacts on bird species using the area, Dr. Smallwood has calculated an estimate of the number of bird fatalities that would result from collisions with the Project. Ex. C, p. 11-12. The FEIR provided renderings of the proposed Project’s building’s facades, which Dr. Smallwood used to estimate the extent of glass that would be used as 579 m2. Id. at 12. Based on Dr.

Smallwood’s own data and review of a number of scientific studies, the mean fatality rate of bird deaths per m2 of glass per year is 0.073. Id. He therefore estimates that the project could result in 42 bird deaths per year, a number which could be up to 3 times higher when accounting for fatalities removed by scavengers or missed by fatality searchers. Id. This death rate would continue every year until the structure were either renovated to reduce bird collisions, or was removed. Id. He concludes by stating that “[i]f the project moves forward as proposed, and annually kills 42 birds protected by state and federal laws, then the project would cause significant unmitigated impacts.” Id.

Dr. Smallwood provides detailed information about the types of factors that would contribute to a Project’s bird collision risks and available mitigation measures. Ex. C, p. 12-17. He recommends that these factors be used to draft “Bird-Safe Guidelines for City of Santa Monica and [] ought to be used to formulate a bird-safe plan for the proposed project.” Id. at 12. As it stands, however, “the proposed project’s design remains insufficiently described to determine the degree to which the project would contribute to relative collision risk.” Id. at 15. Dr. Smallwood concludes that key additional information for impacts assessment and mitigation include “intensity and timing of bird traffic, heights above ground, travel trajectories, and specific behaviors of birds in flight.” Id.

1242 20th Street Wellness Center (SCH 2018011001)

Because this impact was not addressed in the FEIR and Dr. Smallwood has presented substantial evidence of a fair argument that the Project’s windows will impact birds, the City must prepare a Revised EIR to analyze and mitigate the impact of window collisions on bird species.

3. The FEIR failed to address the cumulative impacts of past, ongoing, and future projects on wildlife.

The FEIR failed to prepare an analysis of cumulative effects on wildlife, due to its erroneous conclusion that there was no suitable habitat for species on the Project site.

Ex. C, p. 17. Based on his observations of the project site, Dr. Smallwood concludes that “bird collision mortality is likely ongoing and of large magnitude, but nobody would know about it in the absence of fatality monitoring.” Id. He believes that the EIR should be revised “to not only include an analysis of the project’s potential impacts to bird mortality, but also of its contribution to cumulative impacts of bird-window collision mortality in the City of Santa Monica,” and that these impacts “should be addressed with the formulation of a city ordinance to guide building design, fatality monitoring, and compensatory mitigation.” Id.

IV. CONCLUSION
For the foregoing reasons, SAFER believes that the EIR is wholly inadequate.

SAFER urges the Community Development Department to refrain from recommending certification of the FEIR or recommending approval of the Project in order to allow staff additional time to address the concerns raised herein. Thank you for considering our comments and please include this letter in the record of proceedings for this project.

Sincerely,
Rebecca L. Davis

Pages: 18
Indoor Air Quality Impacts
Indoor air quality (IAQ) directly impacts the comfort and health of building occupants, and the achievement of acceptable IAQ in newly constructed and renovated buildings is a well-recognized design objective. For example, IAQ is addressed by major highperformance building rating systems and building codes (California Building Standards Commission, 2014; USGBC, 2014). Indoor air quality in homes is particularly important because occupants, on average, spend approximately ninety percent of their time indoors with the majority of this time spent at home (EPA, 2011). Some segments of the population that are most susceptible to the effects of poor IAQ, such as the very young and the elderly, occupy their homes almost continuously. Additionally, an increasing number of adults are working from home at least some of the time during the workweek.

Indoor air quality also is a serious concern for workers in hotels, offices and other business establishments.

The concentrations of many air pollutants often are elevated in homes and other buildings relative to outdoor air because many of the materials and products used indoors contain 2 of 18
and release a variety of pollutants to air (Hodgson et al., 2002; Offermann and Hodgson, 2011). With respect to indoor air contaminants for which inhalation is the primary route of exposure, the critical design and construction parameters are the provision of adequate ventilation and the reduction of indoor sources of the contaminants.

Indoor Formaldehyde Concentrations Impact. In the California New Home Study (CNHS) of 108 new homes in California (Offermann, 2009), 25 air contaminants were measured, and formaldehyde was identified as the indoor air contaminant with the highest cancer risk as determined by the California Proposition 65 Safe Harbor Levels (OEHHA, 2017a), No Significant Risk Levels (NSRL) for carcinogens. The NSRL is the daily intake level calculated to result in one excess case of cancer in an exposed population of 100,000 (i.e., ten in one million cancer risk) and for formaldehyde is 40 µg/day. The NSRL concentration of formaldehyde that represents a daily dose of 40 µg is 2 µg/m3, assuming a continuous 24-hour exposure, a total daily inhaled air volume of 20 m3, and 100% absorption by the respiratory system. All of the CNHS homes exceeded this NSRL concentration of 2 µg/m3. The median indoor formaldehyde concentration was 36 µg/m3, and ranged from 4.8 to 136 µg/m3, which corresponds to a median exceedance of the 2 µg/m3 NSRL concentration of 18 and a range of 2.3 to 68.

Therefore, the cancer risk of a resident living in a California home with the median indoor formaldehyde concentration of 36 µg/m3, is 180 per million as a result of formaldehyde alone. The CEQA significance threshold for airborne cancer risk is 10 per million, as established by the South Coast Air Quality Management District (SCAQMD, 2015).

Besides being a human carcinogen, formaldehyde is also a potent eye and respiratory irritant. In the CNHS, many homes exceeded the non-cancer reference exposure levels (RELs) prescribed by California Office of Environmental Health Hazard Assessment (OEHHA, 2017b). The percentage of homes exceeding the RELs ranged from 98% for the Chronic REL of 9 µg/m3 to 28% for the Acute REL of 55 µg/m3.

The primary source of formaldehyde indoors is composite wood products manufactured with urea-formaldehyde resins, such as plywood, medium density fiberboard, and 3 of 18
particleboard. These materials are commonly used in building construction for flooring, cabinetry, baseboards, window shades, interior doors, and window and door trims.

In January 2009, the California Air Resources Board (CARB) adopted an airborne toxics control measure (ATCM) to reduce formaldehyde emissions from composite wood products, including hardwood plywood, particleboard, medium density fiberboard, and also furniture and other finished products made with these wood products (California Air Resources Board 2009). While this formaldehyde ATCM has resulted in reduced emissions from composite wood products sold in California, they do not preclude that homes built with composite wood products meeting the CARB ATCM will have indoor formaldehyde concentrations below cancer and non-cancer exposure guidelines.

A follow up study to the California New Home Study (CNHS) was conducted in 2016- 2018 (Singer et. al., 2019), and found that the median indoor formaldehyde in new homes built after 2009 with CARB Phase 2 Formaldehyde ATCM materials had lower indoor formaldehyde concentrations, with a median indoor concentrations of 22.4 µg/m3 (18.2 ppb) as compared to a median of 36 µg/m3 found in the 2007 CNHS. Unlike in the CNHS study where formaldehyde concentrations were measured with pumped DNPH samplers, the formaldehyde concentrations in the HENGH study were measured with passive samplers, which were estimated to under-measure the true indoor formaldehyde concentrations by approximately 7.5%. Applying this correction to the HENGH indoor formaldehyde concentrations results in a median indoor concentration of 24.1 µg/m3, which is 33% lower than the 36 µg/m3 found in the 2007 CNHS.

Thus, while new homes built after the 2009 CARB formaldehyde ATCM have a 33% lower median indoor formaldehyde concentration and cancer risk, the median lifetime cancer risk is still 120 per million for homes built with CARB compliant composite wood products. This median lifetime cancer risk is more than 12 times the OEHHA 10 in a million cancer risk threshold (OEHHA, 2017a).

With respect to the 1242 20th St. Wellness Center Project, Santa Monica, CA the buildings consist of commercial spaces.

The employees of the commercial spaces are expected to experience significant indoor exposures (e.g., 40 hours per week, 50 weeks per year). These exposures for employees are anticipated to result in significant cancer risks resulting from exposures to formaldehyde released by the building materials and furnishing commonly found in offices, warehouses, residences and hotels.

Because the commercial spaces will be constructed with CARB Phase 2 Formaldehyde ATCM materials, and be ventilated with the minimum code required amount of outdoor air, the indoor formaldehyde concentrations are likely similar to those concentrations observed in residences built with CARB Phase 2 Formaldehyde ATCM materials, which is a median of 24.1 µg/m3 (Singer et. al., 2020)
Assuming that the employees of commercial spaces work 8 hours per day and inhale 20 m3 of air per day, the formaldehyde dose per work-day at the offices is 161 µg/day.

Assuming that these employees work 5 days per week and 50 weeks per year for 45 years (start at age 20 and retire at age 65) the average 70-year lifetime formaldehyde daily dose is 70.9 µg/day.

This is 1.77 times the NSRL (OEHHA, 2017a) of 40 µg/day and represents a cancer risk of 17.7 per million, which exceeds the CEQA cancer risk of 10 per million. This impact should be analyzed in an environmental impact report (“EIR”), and the agency should impose all feasible mitigation measures to reduce this impact. Several feasible mitigation measures are discussed below and these and other measures should be analyzed in an EIR.

Appendix A, Indoor Formaldehyde Concentrations and the CARB Formaldehyde ATCM, provides analyses that show utilization of CARB Phase 2 Formaldehyde ATCM materials will not ensure acceptable cancer risks with respect to formaldehyde emissions from composite wood products.
5 of 18
Even composite wood products manufactured with CARB certified ultra low emitting formaldehyde (ULEF) resins do not insure that the indoor air will have concentrations of formaldehyde the meet the OEHHA cancer risks that substantially exceed 10 per million.

The permissible emission rates for ULEF composite wood products are only 11-15% lower than the CARB Phase 2 emission rates. Only use of composite wood products made with no-added formaldehyde resins (NAF), such as resins made from soy, polyvinyl acetate, or methylene diisocyanate can insure that the OEHHA cancer risk of 10 per million is met.

The following describes a method that should be used, prior to construction in the environmental review under CEQA, for determining whether the indoor concentrations resulting from the formaldehyde emissions of specific building materials/furnishings selected exceed cancer and non-cancer guidelines. Such a design analyses can be used to identify those materials/furnishings prior to the completion of the City’s CEQA review and project approval, that have formaldehyde emission rates that contribute to indoor concentrations that exceed cancer and non-cancer guidelines, so that alternative lower emitting materials/furnishings may be selected and/or higher minimum outdoor air ventilation rates can be increased to achieve acceptable indoor concentrations and incorporated as mitigation measures for this project.

Pre-Construction Building Material/Furnishing Formaldehyde Emissions Assessment This formaldehyde emissions assessment should be used in the environmental review under CEQA to assess the indoor formaldehyde concentrations from the proposed loading of building materials/furnishings, the area-specific formaldehyde emission rate data for building materials/furnishings, and the design minimum outdoor air ventilation rates. This assessment allows the applicant (and the City) to determine, before the conclusion of the environmental review process and the building materials/furnishings are specified, purchased, and installed, if the total chemical emissions will exceed cancer and non-cancer guidelines, and if so, allow for changes in the selection of specific material/furnishings and/or the design minimum outdoor air ventilations rates such that cancer and non-cancer guidelines are not exceeded.

1.) Define Indoor Air Quality Zones. Divide the building into separate indoor air quality zones, (IAQ Zones). IAQ Zones are defined as areas of well-mixed air. Thus, each ventilation system with recirculating air is considered a single zone, and each room or group of rooms where air is not recirculated (e.g. 100% outdoor air) is considered a separate zone. For IAQ Zones with the same construction material/furnishings and design minimum outdoor air ventilation rates. (e.g. hotel rooms, apartments, condominiums, etc.) the formaldehyde emission rates need only be assessed for a single IAQ Zone of that type.

2.) Calculate Material/Furnishing Loading. For each IAQ Zone, determine the building material and furnishing loadings (e.g., m2 of material/m2 floor area, units of furnishings/m2 floor area) from an inventory of all potential indoor formaldehyde sources, including flooring, ceiling tiles, furnishings, finishes, insulation, sealants, adhesives, and any products constructed with composite wood products containing ureaformaldehyde resins (e.g., plywood, medium density fiberboard, particleboard).

3.) Calculate the Formaldehyde Emission Rate. For each building material, calculate the formaldehyde emission rate (µg/h) from the product of the area-specific formaldehyde emission rate (µg/m2-h) and the area (m2) of material in the IAQ Zone, and from each furnishing (e.g. chairs, desks, etc.) from the unit-specific formaldehyde emission rate (µg/unit-h) and the number of units in the IAQ Zone.

NOTE: As a result of the high-performance building rating systems and building codes (California Building Standards Commission, 2014; USGBC, 2014), most manufacturers of building materials furnishings sold in the United States conduct chemical emission rate tests using the California Department of Health “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions for Indoor Sources Using Environmental Chambers,” (CDPH, 2017), or other equivalent chemical emission rate testing methods. Most manufacturers of building furnishings sold in the United States conduct chemical emission rate tests using ANSI/BIFMA M7.1 Standard Test Method for Determining VOC Emissions (BIFMA, 2018), or other equivalent chemical emission rate testing methods.
7 of 18
CDPH, BIFMA, and other chemical emission rate testing programs, typically certify that a material or furnishing does not create indoor chemical concentrations in excess of the maximum concentrations permitted by their certification. For instance, the CDPH emission rate testing requires that the measured emission rates when input into an office, school, or residential model do not exceed one-half of the OEHHA Chronic Exposure Guidelines (OEHHA, 2017b) for the 35 specific VOCs, including formaldehyde, listed in Table 4-1 of the CDPH test method (CDPH, 2017). These certifications themselves do not provide the actual area-specific formaldehyde emission rate (i.e., µg/m2-h) of the product, but rather provide data that the formaldehyde emission rates do not exceed the maximum rate allowed for the certification. Thus, for example, the data for a certification of a specific type of flooring may be used to calculate that the area-specific emission rate of formaldehyde is less than 31 µg/m2-h, but not the actual measured specific emission rate, which may be 3, 18, or 30 µg/m2-h. These area-specific emission rates determined from the product certifications of CDPH, BIFA, and other certification programs can be used as an initial estimate of the formaldehyde emission rate.

If the actual area-specific emission rates of a building material or furnishing is needed (i.e. the initial emission rates estimates from the product certifications are higher than desired), then that data can be acquired by requesting from the manufacturer the complete chemical emission rate test report. For instance if the complete CDPH emission test report is requested for a CDHP certified product, that report will provide the actual areaspecific emission rates for not only the 35 specific VOCs, including formaldehyde, listed in Table 4-1 of the CDPH test method (CDPH, 2017), but also all of the cancer and reproductive/developmental chemicals listed in the California Proposition 65 Safe Harbor Levels (OEHHA, 2017a), all of the toxic air contaminants (TACs) in the California Air Resources Board Toxic Air Contamination List (CARB, 2011), and the 10 chemicals with the greatest emission rates.

Alternatively, a sample of the building material or furnishing can be submitted to a chemical emission rate testing laboratory, such as Berkeley Analytical Laboratory (https://berkeleyanalytical.com), to measure the formaldehyde emission rate. 8 of 18

4.) Calculate the Total Formaldehyde Emission Rate. For each IAQ Zone, calculate the total formaldehyde emission rate (i.e. µg/h) from the individual formaldehyde emission rates from each of the building material/furnishings as determined in Step 3.

5.) Calculate the Indoor Formaldehyde Concentration. For each IAQ Zone, calculate the indoor formaldehyde concentration (µg/m3) from Equation 1 by dividing the total formaldehyde emission rates (i.e. µg/h) as determined in Step 4, by the design minimum outdoor air ventilation rate (m3/h) for the IAQ Zone.

𝐶!" = #!"!#$
$"#
(Equation 1)
where:

Cin = indoor formaldehyde concentration (µg/m3)
Etotal = total formaldehyde emission rate (µg/h) into the IAQ Zone.

Qoa = design minimum outdoor air ventilation rate to the IAQ Zone (m3/h) The above Equation 1 is based upon mass balance theory, and is referenced in Section

3.10.2 “Calculation of Estimated Building Concentrations” of the California Department of Health “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions for Indoor Sources Using Environmental Chambers”, (CDPH, 2017).

6.) Calculate the Indoor Exposure Cancer and Non-Cancer Health Risks. For each IAQ Zone, calculate the cancer and non-cancer health risks from the indoor formaldehyde concentrations determined in Step 5 and as described in the OEHHA Air Toxics Hot Spots Program Risk Assessment Guidelines; Guidance Manual for Preparation of Health Risk Assessments (OEHHA, 2015).

7.) Mitigate Indoor Formaldehyde Exposures of exceeding the CEQA Cancer and/or Non-Cancer Health Risks. In each IAQ Zone, provide mitigation for any formaldehyde exposure risk as determined in Step 6, that exceeds the CEQA cancer risk of 10 per million or the CEQA non-cancer Hazard Quotient of 1.0.

Provide the source and/or ventilation mitigation required in all IAQ Zones to reduce the 9 of 18
health risks of the chemical exposures below the CEQA cancer and non-cancer health risks.

Source mitigation for formaldehyde may include:

1.) reducing the amount materials and/or furnishings that emit formaldehyde

2.) substituting a different material with a lower area-specific emission rate of formaldehyde

Ventilation mitigation for formaldehyde emitted from building materials and/or furnishings may include:

1.) increasing the design minimum outdoor air ventilation rate to the IAQ Zone.

NOTE: Mitigating the formaldehyde emissions through use of less material/furnishings, or use of lower emitting materials/furnishings, is the preferred mitigation option, as mitigation with increased outdoor air ventilation increases initial and operating costs associated with the heating/cooling systems.

Further, we are not asking that the builder “speculate” on what and how much composite materials be used, but rather at the design stage to select composite wood materials based on the formaldehyde emission rates that manufacturers routinely conduct using the California Department of Health “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions for Indoor Sources Using Environmental Chambers,” (CDPH, 2017), and use the procedure described earlier above (i.e. PreConstruction Building Material/Furnishing Formaldehyde Emissions Assessment) to insure that the materials selected achieve acceptable cancer risks from material off gassing of formaldehyde.

Outdoor Air Ventilation Impact. Another important finding of the CNHS, was that the outdoor air ventilation rates in the homes were very low. Outdoor air ventilation is a very important factor influencing the indoor concentrations of air contaminants, as it is the primary removal mechanism of all indoor air generated contaminants. Lower outdoor air exchange rates cause indoor generated air contaminants to accumulate to higher indoor air 10 of 18
concentrations. Many homeowners rarely open their windows or doors for ventilation as a result of their concerns for security/safety, noise, dust, and odor concerns (Price, 2007). In the CNHS field study, 32% of the homes did not use their windows during the 24‐hour Test Day, and 15% of the homes did not use their windows during the entire preceding week. Most of the homes with no window usage were homes in the winter field session.

Thus, a substantial percentage of homeowners never open their windows, especially in the winter season. The median 24‐hour measurement was 0.26 air changes per hour (ach), with a range of 0.09 ach to 5.3 ach. A total of 67% of the homes had outdoor air exchange rates below the minimum California Building Code (2001) requirement of 0.35 ach. Thus, the relatively tight envelope construction, combined with the fact that many people never open their windows for ventilation, results in homes with low outdoor air exchange rates and higher indoor air contaminant concentrations.

The 1242 20th St. Wellness Center Project, Santa Monica, CA is close to roads with moderate to high traffic (e.g., 20th Street, Arizona Avenue, 19th Street, Wilshire Boulevard etc.) as well as air traffic from the Santa Monica Airport, and thus the Project site is a sound impacted site.

According to the 1242 20th St. Wellness Center Project, Santa Monica, CA – Draft Environmental Impact Report (Dudek, 20209), the existing project traffic noise levels reported in Table 4.9-5, range from 55 dBA to 67 dBA CNEL.

As a result of the anticipated high outdoor noise levels, the current project will require a mechanical supply of outdoor air ventilation to allow for a habitable interior environment with closed windows and doors. Such a ventilation system would allow windows and doors to be kept closed at the occupant’s discretion to control exterior noise within building interiors.

PM2.5 Outdoor Concentrations Impact. An additional impact of the nearby motor vehicle traffic associated with this project, are the outdoor concentrations of PM2.5.

According to the 1242 20th St. Wellness Center Project, Santa Monica, CA – Draft 11 of 18
Environmental Impact Report (Dudek, 20209), the Project is located in the South Coast Air Basin, which is a State and Federal non-attainment area for PM2.5.

An air quality analyses should to be conducted to determine the concentrations of PM2.5 in the outdoor and indoor air that people inhale each day. This air quality analyses needs to consider the cumulative impacts of the project related emissions, existing and projected future emissions from local PM2.5 sources (e.g. stationary sources, motor vehicles, and airport traffic) upon the outdoor air concentrations at the Project site. If the outdoor concentrations are determined to exceed the California and National annual average PM2.5 exceedence concentration of 12 µg/m3, or the National 24-hour average exceedence concentration of 35 µg/m3, then the buildings need to have a mechanical supply of outdoor air that has air filtration with sufficient removal efficiency, such that the indoor concentrations of outdoor PM2.5 particles is less than the California and National PM2.5 annual and 24-hour standards.

It is my experience that based on the projected high traffic noise levels, the annual average concentration of PM2.5 will exceed the California and National PM2.5 annual and 24-hour standards and warrant installation of high efficiency air filters (i.e. MERV 13 or higher) in all mechanically supplied outdoor air ventilation systems.

Indoor Air Quality Impact Mitigation Measures
The following are recommended mitigation measures to minimize the impacts upon indoor quality:

Indoor Formaldehyde Concentrations Mitigation. Use only composite wood materials (e.g. hardwood plywood, medium density fiberboard, particleboard) for all interior finish systems that are made with CARB approved no-added formaldehyde (NAF) resins (CARB, 2009). CARB Phase 2 certified composite wood products, or ultra-low emitting formaldehyde (ULEF) resins, do not insure indoor formaldehyde concentrations that are below the CEQA cancer risk of 10 per million. Only composite wood products manufactured with CARB approved no-added formaldehyde (NAF) resins, such as resins 12 of 18
made from soy, polyvinyl acetate, or methylene diisocyanate can insure that the OEHHA cancer risk of 10 per million is met.

Alternatively, conduct the previously described Pre-Construction Building Material/Furnishing Chemical Emissions Assessment, to determine that the combination of formaldehyde emissions from building materials and furnishings do not create indoor formaldehyde concentrations that exceed the CEQA cancer and non-cancer health risks.

It is important to note that we are not asking that the builder “speculate” on what and how much composite materials be used, but rather at the design stage to select composite wood materials based on the formaldehyde emission rates that manufacturers routinely conduct using the California Department of Health “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions for Indoor Sources Using Environmental Chambers”, (CDPH, 2017), and use the procedure described above (i.e.

Pre-Construction Building Material/Furnishing Formaldehyde Emissions Assessment) to insure that the materials selected achieve acceptable cancer risks from material off gassing of formaldehyde.

Outdoor Air Ventilation Mitigation. Provide each habitable room with a continuous mechanical supply of outdoor air that meets or exceeds the California 2016 Building Energy Efficiency Standards (California Energy Commission, 2015) requirements of the greater of 15 cfm/occupant or 0.15 cfm/ft2 of floor area. Following installation of the system conduct testing and balancing to insure that required amount of outdoor air is entering each habitable room and provide a written report documenting the outdoor airflow rates. Do not use exhaust only mechanical outdoor air systems, use only balanced outdoor air supply and exhaust systems or outdoor air supply only systems. Provide a manual for the occupants or maintenance personnel, that describes the purpose of the mechanical outdoor air system and the operation and maintenance requirements of the system.

PM2.5 Outdoor Air Concentration Mitigation. Install air filtration with sufficient PM2.5 removal efficiency (e.g. MERV 13 or higher) to filter the outdoor air entering the 13 of 18
mechanical outdoor air supply systems, such that the indoor concentrations of outdoor PM2.5 particles are less than the California and National PM2.5 annual and 24-hour standards. Install the air filters in the system such that they are accessible for replacement by the occupants or maintenance personnel. Include in the mechanical outdoor air ventilation system manual instructions on how to replace the air filters and the estimated frequency of replacement.

APPENDIX A

INDOOR FORMALDEHYDE CONCENTRATIONS

AND THE

CARB FORMALDEHYDE ATCM
With respect to formaldehyde emissions from composite wood products, the CARB ATCM regulations of formaldehyde emissions from composite wood products, do not assure healthful indoor air quality. The following is the stated purpose of the CARB ATCM regulation - The purpose of this airborne toxic control measure is to “reduce formaldehyde emissions from composite wood products, and finished goods that contain composite wood products, that are sold, offered for sale, supplied, used, or manufactured for sale in California”. In other words, the CARB ATCM regulations do not “assure healthful indoor air quality”, but rather “reduce formaldehyde emissions from composite wood products”.

Just how much protection do the CARB ATCM regulations provide building occupants from the formaldehyde emissions generated by composite wood products? Definitely some, but certainly the regulations do not “assure healthful indoor air quality” when CARB Phase 2 products are utilized. As shown in the Chan 2019 study of new California homes, the median indoor formaldehyde concentration was of 22.4 µg/m3 (18.2 ppb), which corresponds to a cancer risk of 112 per million for occupants with continuous exposure, which is more than 11 times the CEQA cancer risk of 10 per million.

Another way of looking at how much protection the CARB ATCM regulations provide building occupants from the formaldehyde emissions generated by composite wood products is to calculate the maximum number of square feet of composite wood product that can be in a residence without exceeding the CEQA cancer risk of 10 per million for occupants with continuous occupancy.

For this calculation I utilized the floor area (2,272 ft2), the ceiling height (8.5 ft), and the number of bedrooms (4) as defined in Appendix B (New Single-Family Residence Scenario) of the Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions for Indoor Sources Using Environmental Chambers, Version 1.1, 2017, California 17 of 18
Department of Public Health, Richmond, CA. https://www.cdph.ca.gov/Programs/CCDPHP/ DEODC/EHLB/IAQ/Pages/VOC.aspx.

For the outdoor air ventilation rate I used the 2019 Title 24 code required mechanical ventilation rate (ASHRAE 62.2) of 106 cfm (180 m3/h) calculated for this model residence.

For the composite wood formaldehyde emission rates I used the CARB ATCM Phase 2 rates.

The calculated maximum number of square feet of composite wood product that can be in a residence, without exceeding the CEQA cancer risk of 10 per million for occupants with continuous occupancy are as follows for the different types of regulated composite wood products.

Medium Density Fiberboard (MDF) – 15 ft2 (0.7% of the floor area), or Particle Board – 30 ft2 (1.3% of the floor area), or
Hardwood Plywood – 54 ft2 (2.4% of the floor area), or
Thin MDF – 46 ft2 (2.0 % of the floor area).

For offices and hotels the calculated maximum amount of composite wood product (% of floor area) that can be used without exceeding the CEQA cancer risk of 10 per million for occupants, assuming 8 hours/day occupancy, and the California Mechanical Code minimum outdoor air ventilation rates are as follows for the different types of regulated composite wood products.

Medium Density Fiberboard (MDF) – 3.6 % (offices) and 4.6% (hotel rooms), or Particle Board – 7.2 % (offices) and 9.4% (hotel rooms), or Hardwood Plywood – 13 % (offices) and 17% (hotel rooms), or Thin MDF – 11 % (offices) and 14 % (hotel rooms)
Clearly the CARB ATCM does not regulate the formaldehyde emissions from composite wood products such that the potentially large areas of these products, such as for flooring, baseboards, interior doors, window and door trims, and kitchen and bathroom cabinetry, 18 of 18
could be used without causing indoor formaldehyde concentrations that result in CEQA cancer risks that substantially exceed 10 per million for occupants with continuous occupancy.

Even composite wood products manufactured with CARB certified ultra low emitting formaldehyde (ULEF) resins do not insure that the indoor air will have concentrations of formaldehyde the meet the OEHHA cancer risks that substantially exceed 10 per million.

The permissible emission rates for ULEF composite wood products are only 11-15% lower than the CARB Phase 2 emission rates. Only use of composite wood products made with no-added formaldehyde resins (NAF), such as resins made from soy, polyvinyl acetate, or methylene diisocyanate can insure that the OEHHA cancer risk of 10 per million is met.

If CARB Phase 2 compliant or ULEF composite wood products are utilized in construction, then the resulting indoor formaldehyde concentrations should be determined in the design phase using the specific amounts of each type of composite wood product, the specific formaldehyde emission rates, and the volume and outdoor air ventilation rates of the indoor spaces, and all feasible mitigation measures employed to reduce this impact (e.g. use less formaldehyde containing composite wood products and/or incorporate mechanical systems capable of higher outdoor air ventilation rates). See the procedure described earlier (i.e. Pre-Construction Building Material/Furnishing Formaldehyde Emissions Assessment) to insure that the materials selected achieve acceptable cancer risks from material off gassing of formaldehyde.

Alternatively, and perhaps a simpler approach, is to use only composite wood products (e.g. hardwood plywood, medium density fiberboard, particleboard) for all interior finish systems that are made with CARB approved no-added formaldehyde (NAF) resins.

Subject: Comments on the 1242 20th Street Wellness Center Project (SCH No. 2018011001) Dear Ms. Fuentes,
We have reviewed the October 2021 Final Environmental Impact Report (“FEIR”) and December 2020 Draft Environmental Impact Report (“DEIR”) for the 1242 20th Street Wellness Center Project (“Project”) located in the City of Santa Monica (“City”). The Project proposes to construct 54,000-SF of research and development (R&D) space, 18,812-SF of clinic/medical office space, and 743-SF of related support space, as well as 275 parking spaces, on the 1.03-acre site.

Our review concludes that the FEIR fails to adequately evaluate the Project’s air quality, health risk, and greenhouse gas impacts. As a result, emissions and health risk impacts associated with construction and operation of the proposed Project are underestimated and inadequately addressed. An updated EIR should be prepared to adequately assess and mitigate the potential air quality, health risk, and greenhouse gas impacts that the project may have on the surrounding environment.

Air Quality
Unsubstantiated Input Parameters Used to Estimate Project Emissions The FEIR’s air quality analysis relies on emissions calculated with CalEEMod.2016.3.2 (p. 4.2-30).1 CalEEMod provides recommended default values based on site-specific information, such as land use type, meteorological data, total lot acreage, project type and typical equipment associated with project type. If more specific project information is known, the user can change the default values and input 1 CAPCOA (November 2017) CalEEMod User’s Guide, http://www.aqmd.gov/docs/defaultsource/caleemod/01_user-39-s-guide2016-3-2_15november2017.pdf?sfvrsn=4. 2 project-specific values, but the California Environmental Quality Act (“CEQA”) requires that such changes be justified by substantial evidence. Once all of the values are inputted into the model, the Project's construction and operational emissions are calculated, and "output files" are generated. These output files disclose to the reader what parameters are utilized in calculating the Project's air pollutant emissions and make known which default values are changed as well as provide justification for the values selected.

When reviewing the Project’s CalEEMod output files, provided in the Air Quality and Greenhouse Gas Emissions Calculations and Health Risk Assessment (“AQ & GHG Report”) as Appendix B to the FEIR, we found that several model inputs were not consistent with information disclosed in the FEIR. As a result, the Project’s construction and operational emissions are underestimated. As such, an updated EIR should be prepared to include an updated air quality analysis that adequately evaluates the impacts that construction and operation of the Project will have on local and regional air quality.

Unsubstantiated Reduction to Acres of Grading Value
Review of the CalEEMod output files demonstrates that the “Santa Monica Wellness Center” and “Santa Monica Wellness Center - Construction HRA” models include a manual reduction to the default acres of grading value (see excerpt below) (Appendix B, pp. 121, 160, 195, 259).

As you can see from the excerpt above, the acres of grading value was reduced by approximately 98%, from the default value of 60.38- to 1.5-acres.As previously mentioned, the CalEEMod User’s Guide requires any changes to model defaults be justified.2 According to the “User Entered Comments & NonDefault Data” table, the justification provided for this change is: “58,000 cy soil exported” (Appendix B, pp. 120, 159, 194, 258). Furthermore, the FEIR indicates that the Project site is 1.03 acres (p. 1-1).

However, these justifications remain insufficient for two reasons.

First, the justification provided by the “User Entered Comments & Non-Default Data” table only references the amount of required material export, not the revised acres of grading value.

Second, according to the CalEEMod User’s Guide:
“[T]he dimensions (e.g., length and width) of the grading site have no impact on the calculation, only the total area to be graded. In order to properly grade a piece of land multiple passes with equipment may be required. The acres is based on the equipment list and days in grading or site preparation phase according to the anticipated maximum number of acres a given piece of equipment can pass over in an 8-hour workday.”3
2 CalEEMod User Guide, available at: http://www.caleemod.com/, p. 2, 9 3 “Appendix A Calculation Details for CalEEMod.” available at: http://www.aqmd.gov/docs/defaultsource/caleemod/02_appendix-a2016-3-2.pdf?sfvrsn=6, p. 9. 3 As demonstrated above, the acres of grading value is based on construction equipment and the length of the grading or site preparation phase. Thus, as the dimensions of the Project site have no impact on the acres of grading value, we cannot verify the revised acres of grading value.

This unsubstantiated reduction presents an issue, as CalEEMod uses the acres of grading value to estimate the dust emissions associated with grading.4 Thus, by including an unsubstantiated reduction to the default acres of grading value, the models may underestimate the Project’s construction-related emissions and should not be relied upon to determine Project significance.

Unsubstantiated Off-Road Construction Equipment Usage Hours Review of the CalEEMod output files demonstrates that the “Santa Monica Wellness Center” and “Santa Monica Wellness Center - Construction HRA” models include several reductions to the default off-road construction equipment usage hours (see excerpt below) (Appendix B, pp. 121, 160, 195, 260).

As previously mentioned, the CalEEMod User’s Guide requires any changes to model defaults be justified.5 According to the “User Entered Comments and Non-Default Data” table, the justification provided for these changes is: “See 3.0 Construction Detail” (Appendix B, pp. 120, 159, 194, 258).

Furthermore, the FEIR provides the following construction scenario assumptions (p. 4.2-32, Table 4.2-8):
4 “Appendix A Calculation Details for CalEEMod.” available at: http://www.aqmd.gov/docs/defaultsource/caleemod/02_appendix-a2016-3-2.pdf?sfvrsn=6, p. 9. 5 CalEEMod User Guide, available at: http://www.caleemod.com/, p. 2, 9 4 However, these justifications remain insufficient for two reasons.

First, the source provided for the assumed construction equipment usage hours is Appendix B, the CalEEMod output files themselves. This is incorrect, as the Project documents should substantiate the changes included in the CalEEMod model, not vice versa. According to the CalEEMod User’s Guide:
“CalEEMod was also designed to allow the user to change the defaults to reflect site- or projectspecific information, when available, provided that the information is supported by substantial evidence as required by CEQA” (emphasis added).6
Here, as the FEIR fails to provide substantial evidence to support the revised usage hours, we cannot verify the changes.

Second, the FEIR states:
“It was assumed that all equipment used during each construction subphase would be operating 8 hours per day, 5 days per week” (p. 4.2-31).

As such, the information provided in the Construction Scenario Assumptions table is inconsistent with the FEIR. Thus, the revised off-road construction usage hours are incorrect and underestimated within the model.
6 CalEEMod Model 2013.2.2 User’s Guide, available at: http://www.aqmd.gov/docs/defaultsource/caleemod/usersguideSept2016.pdf?sfvrsn=6, p. 12. 5 These unsubstantiated reductions present an issue, as CalEEMod uses the off-road equipment input parameters to calculate the emissions associated with off-road construction equipment.7 By including unsubstantiated changes to the default off-road construction equipment usage hours, the models may underestimate the Project’s construction-related emissions and should not be relied upon to determine Project significance.

Failure to Substantiate Demolition and Reduction to Number of Demolition Hauling Trips Review of the CalEEMod output files demonstrates that the “Santa Monica Wellness Center” and “Santa Monica Wellness Center - Construction HRA” models include 164 demolition hauling trips (Appendix B, pp. 126, 165, 200, 264).

Furthermore, review of the CalEEMod output files demonstrates that the models include a manual reduction to the number of demolition hauling trips from the default value of 924- to 164-trips (see excerpt below) (Appendix B, pp. 122, 161, 196, 260).

However, the number of demolition hauling trips is unsubstantiated. According to the CalEEMod User’s Guide:
“Haul trips are based on the amount of material that is demolished, imported or exported assuming a truck can handle 16 cubic yards of material.”8 Therefore, CalEEMod calculates a default number of hauling trips based upon the amount of demolition material inputted into the model. However, the FEIR fails to disclose the specific square footage of 7 CalEEMod User Guide, available at: http://www.caleemod.com/, p. 32. 8 http://www.aqmd.gov/docs/default-source/caleemod/02_appendix-a2016-3-2.pdf?sfvrsn=6, p. 14 6 facilities to be demolished or the tons of debris resulting from this demolition. Specifically, regarding the amount of demolition required for Project construction, FEIR states:
“Implementation of the proposed project would require demolition of the following:
• 1-story rear parking garage (adjacent to 19th Court) of the GKGM Building • 2-story, 7-unit building
• 2-story, 3-unit building
• surface parking lot, subterranean utilities, and four driveway curb cuts adjacent to 20th Street and one driveway curb cut adjacent to Arizona Avenue • removal of stone veneer along the Arizona Avenue-facing side of the administrative portion of GKGM Building
• removal of exterior door along the interior driveway side of the administrative portion of GKGM Building
• a portion of the internal walkway adjacent to the former chapel of the GKGM building” (p. 3-13).

Thus, as the FEIR fails to specify any amount demolition, we cannot verify that the default hauling trip number of 924 trips is the result of the correct input of demolition. As such, demolition may be underestimated in the model. Furthermore, the FEIR fails to mention or justify the reduction to the default demolition hauling trip number whatsoever. As a result, the revised value of 164 trips also remains unsupported.

This underestimation presents an issue, as the total amount of demolition material is used by CalEEMod to determine emissions associated with this phase of construction; the three primary operations that generate dust emission during the demolition phase are mechanical or explosive dismemberment, site removal of debris, and on-site truck traffic on paved and unpaved road.9 By failing to include the total amount of required demolition, the models underestimate emissions associated with fugitive dust, debris removal, as well as exhaust from hauling trucks traveling to and from the site, and should not be relied upon to determine the significance of the Project’s air quality impacts.

Unsubstantiated Worker and Vendor Trip Numbers
Review of the CalEEMod output files demonstrates that the “Santa Monica Wellness Center” model includes several changes to the default vendor and worker trip numbers (see excerpts below) (Appendix B, pp. 122, 161, 196).
9 CalEEMod User Guide, Appendix A, p. 11, available at: http://www.caleemod.com/ 7 As previously mentioned, the CalEEMod User’s Guide requires any changes to model defaults be justified.10 According to the “User Entered Comments & Non-Default Data” table, the justification provided for these changes is:
“Revised haul trips to include pavement demolition trips. Assumed 10 CY per load resulting in 11,600 haul trips. Rounded up number of trips. Assumed two water trucks during grading” (Appendix B, pp. 120, 159, 194).

However, these changes remain unsupported for three reasons.

First, the justification provided by the “User Entered Comments & Non-Default Data” table only references hauling trips, not worker or vendor trips.

Second, the FEIR indicates that “[a]n estimated 4 to 39 construction workers would be on-site at any one time” (p. 3-13). As such, in order to conduct the most conservative analysis, the model should have accounted for the potential of all 39 workers being present on the Project site. Thus, the model should have included 78 one-way worker trips during all phases of construction.

Third, the FEIR fails to mention or justify revised vendor trip numbers whatsoever. According to the CalEEMod User’s Guide:
“CalEEMod was also designed to allow the user to change the defaults to reflect site- or projectspecific information, when available, provided that the information is supported by substantial evidence as required by CEQA.” 11
Here, as the FEIR and associated documents fail to provide substantial evidence to support the revised vendor trip numbers, we cannot verify the changes.
10 CalEEMod User Guide, available at: http://www.caleemod.com/, p. 2, 9 11 CalEEMod User Guide, available at: http://www.caleemod.com/, p. 12. 8 These unsubstantiated reductions present an issue, as CalEEMod uses the vendor and worker trip numbers to estimate the construction-related emissions associated with on-road vehicles.12 Thus, by including unsubstantiated changes to the default vendor and worker trip numbers, the model may underestimate the Project’s mobile-source construction-related emissions and should not be relied upon to determine Project significance.

Failure to Model Material Export
Regarding the material import and export required for Project construction, the FEIR states:
“Excavation is anticipated to generate approximately 58,000 cubic yards of soil that would be exported via haul truck trips” (p. 3-13).

As such, the Project should have included 58,000 cubic yards (“cy”) of material export in the model.

However, review of the CalEEMod output files demonstrates that the “Santa Monica Wellness Center - Construction HRA” model fails to include any amount of material export (Appendix B, pp. 258-261). As such, the material export required for Project construction is underestimated and the model is inconsistent with the FEIR.

This underestimation presents an issue, as the inclusion of material export within the model is necessary to calculate emissions produced from material movement, including truck loading/unloading and additional hauling truck trips.13 Thus, by failing to include the amount of material export required for Project construction, the model underestimates the Project’s construction-related emissions and should not be relied upon to determine Project significance.

Diesel Particulate Matter Health Risk Emissions Inadequately Evaluated The FEIR estimates that the mitigated excess cancer risk posed to nearby, existing sensitive receptors as a result of Project construction would be 7.23 in one million, which would not exceed the SCAQMD significance threshold of 10 in one million (see excerpt below) (p. 4.2-51, Table 4.2-14). 12 CalEEMod User Guide, available at: http://www.caleemod.com/, p. 34. 13 CalEEMod User’s Guide, available at: http://www.caleemod.com/, p. 3, 26. 9 Furthermore, regarding the health risk impacts associated with Project operation, the FEIR states:
“Operational TAC impacts could occur if the project would generate significant sources of operational TACs including diesel particulate matter. […] The proposed project would develop a Wellness Center with research & development and clinical/medical office space. Given the research & development and clinical/medical office uses, project operations would generate minimal number of delivery trucks (associated with trash, supply deliveries, etc.) per day. Daily truck trips would not exceed 100 trucks per day or more than 40 trucks with operating transport refrigeration units. Furthermore, trucks are required to comply with the applicable provisions of the CARB Truck and Bus regulation to minimize and reduce PM and NOX emissions from existing diesel trucks. Therefore, impacts would be less than significant” (p. 4.2-48).

As demonstrated above, the FEIR concludes that the Project would result in a less-than-significant operational health risk impact because the minimal number of daily trucks trips and compliance with CARB regulations would not result in significant toxic air contaminant (“TAC”) emissions. However, the FEIR’s evaluation of the Project’s potential health risk impacts, as well as the subsequent less-thansignificant impact conclusion, is incorrect for four reasons.

First, the FEIR’s construction HRA is incorrect. As indicated by the Health Risk Assessment Report (“HRA Report”), provided within Appendix B to the FEIR, the construction relies upon exhaust PM10 emissions estimates from a flawed air model (p. 9). As previously discussed, when we reviewed the Project's CalEEMod output files, provided in the AQ & GHG Report as Appendix B to the FEIR, we found that several of the values inputted into the model are not consistent with information disclosed in the FEIR.

As a result, the HRA utilizes an underestimated diesel particulate matter (“DPM”) concentration to calculate the health risk associated with Project construction. As such, the FEIR’s construction HRA underestimates the Project’s cancer risk and should not be relied upon to determine Project significance.

Second, by failing to prepare a quantified operational HRA, the Project is inconsistent with CEQA’s requirement to correlate the increase in emissions that the Project would generate to the adverse 10 impacts on human health caused by those emissions. Despite the FEIR’s claim that Project operation would not exceed 100 daily truck trips, review of the CalEEMod output files demonstrates that Project operation will in fact generate approximately 100 weekday truck trips, 14 which would generate
additional exhaust emissions and continue to expose nearby sensitive receptors to DPM emissions (Appendix B, pp. 149-150, 188-189, 223-224). The FEIR’s vague discussion of potential TACs associated with Project operation fails to indicate the concentrations at which such pollutants would trigger adverse health effects. Thus, without making a reasonable effort to connect the Project’s operational TAC emissions to the potential health risks posed to nearby receptors, the Project is inconsistent with CEQA’s requirement to correlate the increase in TAC emissions with potential adverse impacts on human health.

Third, the Office of Environmental Health Hazard Assessment (“OEHHA”), the organization responsible for providing guidance on conducting HRAs in California, released its most recent Risk Assessment Guidelines: Guidance Manual for Preparation of Health Risk Assessments in February 2015, as referenced by the FEIR (p. 4.2-47).15 The OEHHA document recommends that exposure from projects lasting more than 6 months be evaluated for the duration of the project and recommends that an exposure duration of 30 years be used to estimate individual cancer risk for the maximally exposed individual resident (“MEIR”).16 Even though we were not provided with the expected lifetime of the Project, we can reasonably assume that the Project will operate for at least 30 years, if not more.

Therefore, we recommend that health risk impacts from Project operation also be evaluated, as a 30- year exposure duration vastly exceeds the 6-month requirement set forth by OEHHA. This recommendation reflects the most recent state health risk policies, and as such, we recommend that an analysis of health risk impacts posed to nearby sensitive receptors from Project operation be included in an updated EIR for the Project.

Fourth, while the FEIR includes an HRA evaluating the health risk impacts to nearby, existing receptors as a result of Project construction, the HRA fails to evaluate the cumulative lifetime cancer risk to nearby, existing receptors as a result of Project construction and operation together. According to OEHHA guidance, as referenced by the FEIR, “the excess cancer risk is calculated separately for each age grouping and then summed to yield cancer risk at the receptor location” (p. 4.2-47).17 However, the FEIR’s HRA fails to sum each age bin to evaluate the total cancer risk over the course of the Project’s total construction and operation. This is incorrect and thus, an updated analysis should quantify the entirety of the Project’s construction and operational health risks, and then sum them to compare to the SCAQMD threshold of 10 in one million, as referenced by the FEIR (p. 4.2-29, Table 4.2-6). 14 Calculated: (1,286.75 weekday vehicle trips) * (0.014562 LHD1 + 0.005806 LHD2 + 0.021810 MDV + 0.035336 HHD truck fleet mix) = ~100 total weekday truck trips.

https://oehha.ca.gov/media/downloads/crnr/2015guidancemanual.pdf p. 8-4 11 Screening-Level Analysis Demonstrates Significant Impacts In order to conduct our screening-level risk assessment, we relied upon AERSCREEN, a screening level air quality dispersion model.18 The model replaced SCREEN3, and AERSCREEN is included in the OEHHA19 and the California Air Pollution Control Officers Associated (“CAPCOA”)20 guidance as the appropriate air dispersion model for Level 2 health risk screening assessments (“HRSAs”). A Level 2 HRSA utilizes a limited amount of site-specific information to generate maximum reasonable downwind concentrations of air contaminants to which nearby sensitive receptors may be exposed. If an unacceptable air quality hazard is determined to be possible using AERSCREEN, a more refined modeling approach is required prior to approval of the Project.

We prepared a preliminary HRA of the Project’s operational health risk impact to nearby sensitive receptors using the Project’s net annual PM10 exhaust estimates. Consistent with recommendations set forth by OEHHA, we assumed residential exposure begins during the third trimester stage of life.

Subtracting the 676-day construction period from the total residential duration of 30 years, we assumed that after Project construction, the sensitive receptor would be exposed to the Project’s operational DPM for an additional 28.15 years, approximately. The FEIR’s annual CalEEMod output file indicates that operational activities will generate approximately 25 pounds of DPM per year throughout operation.21 The AERSCREEN model relies on a continuous average emission rate to simulate maximum downward concentrations from point, area, and volume emission sources. To account for the variability in equipment usage and truck trips over Project operation, we calculated an average DPM emission rate by the following equation:

Using this equation, we estimated an operational emission rate of 0.000365 g/s. Construction and operational activity was simulated as a 1.03-acre rectangular area source in AERSCREEN with approximate dimensions of 91 by 46 meters. A release height of three meters was selected to represent the height of exhaust stacks on operational equipment and other heavy-duty vehicles, and an initial vertical dimension of one and a half meters was used to simulate instantaneous plume dispersion upon release. An urban meteorological setting was selected with model-default inputs for wind speed and direction distribution.

The AERSCREEN model generates maximum reasonable estimates of single-hour DPM concentrations from the Project site. EPA guidance suggests that in screening procedures, the annualized average 18 U.S. EPA (April 2011) AERSCREEN Released as the EPA Recommended Screening Model, http://www.epa.gov/ttn/scram/guidance/clarification/20110411_AERSCREEN_Release_Memo.pdf 19 OEHHA (February 2015) Risk Assessment Guidelines Guidance Manual for Preparation of Health Risk Assessments, https://oehha.ca.gov/media/downloads/crnr/2015guidancemanual.pdf. 20 CAPCOA (July 2009) Health Risk Assessments for Proposed Land Use Projects, http://www.capcoa.org/wpcontent/uploads/2012/03/CAPCOA_HRA_LU_Guidelines_8-6-09.pdf. 21 See Attachment A for calculations. 12 concentration of an air pollutant be estimated by multiplying the single-hour concentration by 10%.22 According to the FEIR, the nearest sensitive receptors are multi-family residences located approximately 20 feet, or 6 meters, from the Project (p. 4.3-1). However, review of the AERSCREEN output files demonstrates that the maximally exposed receptor is located approximately 50 meters, or 160 feet, from the Project site. As such, the single-hour concentration estimated by AERSCREEN for Project operation is approximately 1.909 µg/m3 DPM at approximately 50 meters downwind. Multiplying this single-hour concentration by 10%, we get an annualized average concentration of 0.1909 µg/m3 for Project operation at the MEIR.

We calculated the excess cancer risk to the MEIR using applicable HRA methodologies prescribed by OEHHA, as referenced by the FEIR (p. 4.2-47). Consistent with the 676-day construction schedule utilized in the Project’s CalEEMod output files, the annualized averaged concentration for operation was used for the latter 0.4 years of the infant stage of life (0 – 2 years), as well as the entire childhood (2 – 16 years) and the adult (16 – 30 years) stages of life.

Consistent with the FEIR’s construction HRA, provided in the HRA Report, we used Age Sensitivity Factors (“ASFs”) to account for the heightened susceptibility of young children to the carcinogenic toxicity of air pollution (p. 6). When applying ASFs, the quantified cancer risk should be multiplied by a factor of ten during the infant (0 – 2 years) stage of life, and a factor of three during the child stage of life (2 – 16 years). Furthermore, in accordance with the guidance set forth by OEHHA, we used the 95th percentile breathing rates for infants.23 Finally, according to SCAQMD guidance, we used a Fraction of Time At Home (“FAH”) Value of 1 for the infant and child receptors, and 0.73 for the adult receptors.24 We also used a cancer potency factor of 1.1 (mg/kg-day)-1 and an averaging time of 25,550 days. The results of our calculations are shown below.

* Construction cancer risk calculated separately in the FEIR.

As demonstrated in the table above, the excess cancer risks to infants, children, and adults at the MEIR located approximately 50 meters away, over the course of Project operation, are approximately 12.5,

69.1, and 7.67 in one million, respectively. The excess cancer risk associated with the Project operation over the course of a residential lifetime is approximately 89.3 in one million. When summing the Project’s operational cancer risk, as estimated by SWAPE, with the FEIR’s construction-related cancer risk of 7.23 in one million, we estimate an excess cancer risk of approximately 96.5 in one million over the course of a residential lifetime (30 years) (p. 4.2-51, Table 4.2-14). 25 As such, the lifetime cancer risks
exceed the SCAQMD threshold of 10 in one million, thus resulting in a potentially significant impact not previously addressed or identified by the FEIR.

An agency must include an analysis of health risks that connects the Project’s air emissions with the health risk posed by those emissions. Our analysis represents a screening-level HRA, which is known to be conservative and tends to err on the side of health protection. 26 The purpose of the screening-level construction and operational HRA shown above is to demonstrate the link between the proposed Project’s emissions and the potential health risk. Our screening-level HRA demonstrates that construction and operation of the Project could result in a potentially significant health risk impact, when correct exposure assumptions and up-to-date, applicable guidance are used. Therefore, since our screening-level HRA indicates a potentially significant impact, an updated EIR should be prepared and include updated, quantified air pollution model as well as an updated, quantified refined HRA which 25 Calculated: 89.3 in one million + 7.23 in one million = 96.5 in one million. 26 “Risk Assessment Guidelines Guidance Manual for Preparation of Health Risk Assessments.” OEHHA, February 2015, available at: https://oehha.ca.gov/media/downloads/crnr/2015guidancemanual.pdf, p. 1-5 14 adequately and accurately evaluates health risk impacts associated with both Project construction and operation.

Greenhouse Gas
Failure to Adequately Evaluate Greenhouse Gas Impacts
The FEIR estimates that the Project would generate net annual greenhouse gas (“GHG”) emissions of 1,147.12 metric tons of carbon dioxide equivalents per year (“MT CO2e/year”) (p. 4.6-35, Table 4.6-4).

However, the FEIR elects not to compare emissions to a threshold. Instead, the FEIR relies upon the Project’s consistency with the CARB’s Climate Change Scoping Plan, SCAG’s 2020-2045 RTP/SCS, and the City of Santa Monica’s LUCE, Sustainable City Plan, Green Building and Energy Code, and Climate Action and Adaptation Plan to conclude that the Project would result in a less-than-significant GHG impact (p.

4.6-35 - 4.6-43). However, the FEIR’s GHG analysis, as well as the subsequent less-than-significant impact conclusion, is incorrect for four reasons:
(1) The FEIR’s quantitative GHG analysis relies upon an incorrect and unsubstantiated air model; (2) The FEIR’s unsubstantiated air model indicates a potentially significant impact; (3) The FEIR fails to consider the performance-based standards under CARB’s Scoping Plan; and (4) The FEIR fails to consider the performance-based standards under SCAG’s RTP/SCS. 1) Incorrect and Unsubstantiated Quantitative Analysis of Emissions As previously stated, the FEIR estimates that the Project would generate net annual GHG emissions of 1,147.12 MT CO2e/year (p. 4.6-35, Table 4.6-4). However, the FEIR’s quantitative GHG analysis is unsubstantiated. As previously discussed, when we reviewed the Project's CalEEMod output files, provided in the AQ & GHG Report as Appendix B to the FEIR, we found that several of the values inputted into the model are not consistent with information disclosed in the FEIR. As a result, the model underestimates the Project’s emissions, and the FEIR’s quantitative GHG analysis should not be relied upon to determine Project significance. An updated EIR should be prepared that adequately assesses the potential GHG impacts that construction and operation of the proposed Project may have on the surrounding environment.
15 2) Failure to Identify a Potentially Significant GHG Impact In an effort to quantitatively evaluate the Project’s GHG emissions, we compared the Project’s GHG emissions, as estimated by the FEIR, to the SCAQMD 2035 efficiency target of 3.0 MT CO2e/SP/year, which was calculated by applying a 40% reduction to the 2020 targets.27 When applying this threshold, the Project’s incorrect and unsubstantiated air model indicates a potentially significant GHG impact. 28 As
previously stated, the FEIR estimates that the Project would generate net annual GHG emissions of 1,147.12 MT CO2e/year (p. 4.6-35, Table 4.6-4). Furthermore, according to CAPCOA’s CEQA & Climate Change report, service population is defined as “the sum of the number of residents and the number of jobs supported by the project.”29 The FEIR estimates that the Project would employ approximately 206 people (p. 3-12). As the Project does not include any residential land uses, we estimate a service population of 206 people.
30 When dividing the Project’s net annual GHG emissions, as estimated by the FEIR, by a service population of 100 people, we find that the Project would emit approximately 5.57 MT CO2e/SP/year (see table below).31
Greenhouse Gas Emissions per Capita,
Exceedances under SCAQMD 2035 Service Population Efficiency Target Source FEIR Model
Annual Emissions (MT CO2e/year) 1,147.12
Service Population 206
Service Population Efficiency (MT CO2e/SP/year) 5.57
2035 SCAQMD Target (MT CO2e/SP/year) 3.0
Exceeds? Yes
As demonstrated above, the Project’s service population efficiency value, as estimated by the FEIR’s provided net annual GHG emission estimates and service population, exceed the SCAQMD 2035 efficiency target of 3.0 MT CO2e/SP/year, indicating a potentially significant impact not previously identified or addressed by the FEIR. As a result, the FEIR’s less-than-significant GHG impact conclusion should not be relied upon. An updated EIR should be prepared, including an updated GHG analysis and incorporating additional mitigation measures to reduce the Project’s GHG emissions to less-thansignificant levels. 27 “Minutes for the GHG CEQA Significance Threshold Stakeholder Working Group #15.” SCAQMD, September 2010, available at: http://www.aqmd.gov/docs/default-source/ceqa/handbook/greenhouse-gases-(ghg)-ceqasignificance-thresholds/year-2008-2009/ghg-meeting-15/ghg-meeting-15-minutes.pdf, p. 2. 28 “Minutes for the GHG CEQA Significance Threshold Stakeholder Working Group #15.” SCAQMD, September 2010, available at: http://www.aqmd.gov/docs/default-source/ceqa/handbook/greenhouse-gases-(ghg)-ceqasignificance-thresholds/year-2008-2009/ghg-meeting-15/ghg-meeting-15-minutes.pdf, p. 2. 29 CAPCOA (Jan. 2008) CEQA & Climate Change, p. 71-72, http://www.capcoa.org/wpcontent/uploads/2012/03/CAPCOA-White-Paper.pdf. 30 Calculated: 0 residents + 206 employees = 206 service population. 31 Calculated: (1147.12 MT CO2e/year) / (206 service population) = (5.57 MT CO2e/SP/year). 16 3) Failure to Consider Performance-based Standards Under CARB’s 2017 Scoping Plan As previously discussed, the FEIR relies upon the Project’s consistency with CARB’s 2017 Scoping Plan to determine Project GHG significance (p. 4.6-35 - 4.6-43). However, this is incorrect, as the FEIR fails to consider performance-based measures proposed by CARB.
i. Passenger & Light Duty VMT Per Capita Benchmarks per SB 375 In reaching the State’s long-term GHG emission reduction goals, CARB’s 2017 Scoping Plan explicitly cites to SB 375 and the VMT reductions anticipated under the implementation of Sustainable Community Strategies.32 CARB has identified the population and daily VMT from passenger autos and light-duty vehicles at the state and county level for each year between 2010 to 2050 under a “baseline scenario” that includes “current projections of VMT included in the existing Regional Transportation Plans/Sustainable Communities Strategies (RTP/SCSs) adopted by the State’s 18 Metropolitan Planning Organizations (MPOs) pursuant to SB 375 as of 2015.”33 By dividing the projected daily VMT by the population, we calculated the daily VMT per capita for each year at the state and county level for 2010 (baseline year), 2025 (Project operational year), and 2030 (target years under SB 32) (see table below). 2017 Scoping Plan Daily VMT Per Capita

An updated EIR should be prepared for the proposed Project to provide additional information and analysis to conclude less-than-significant GHG impacts. 4) Failure to Consider Performance-based Standards Under CARB’s 2017 Scoping Plan Here, as discussed above, the FEIR concludes that the Project would be consistent with SCAG’s RTP/SCS (p. 4.6-35 - 4.6-43). However, the FEIR fails to consider whether or not the Project meets any of the specific performance-based goals underlying SCAG’s RTP/SCS and SB 375, such as: i) per capita GHG emission targets, or ii) daily vehicles miles traveled (“VMT”) per capita benchmarks. i. SB 375 Per Capita GHG Emission Goals
SB 375 was signed into law in September 2008 to enhance the state’s ability to reach AB 32 goals by directing CARB to develop regional 2020 and 2035 GHG emission reduction targets for passenger 32 “California’s 2017 Climate Change Scoping Plan.” CARB, November 2017, available at:
https://ww3.arb.ca.gov/cc/scopingplan/scoping_plan_2017.pdf, p. 25, 98, 101-103. 33 “Supporting Calculations for 2017 Scoping Plan-Identified VMT Reductions,” Excel Sheet “Readme.” CARB, January 2019, available at: https://ww2.arb.ca.gov/sites/default/files/2019- 01/sp_mss_vmt_calculations_jan19_0.xlsx.
17 vehicles (autos and light-duty trucks). In March 2018, CARB adopted updated regional targets requiring a 19 percent decrease in VMT for the SCAG region by 2035. This goal is reflected in SCAG’s 2020 RTP/SCS Program Environmental Impact Report (“PEIR”), in which the 2020 RTP/SCS PEIR updates the per capita emissions to 18.8 lbs/day in 2035 (see excerpt below). 34 As the FEIR fails to evaluate the Project’s consistency with the SCAG’s per capita emissions, the FEIR’s claim that the proposed Project would not conflict with SCAG’s RTP/SCS is unsupported. An updated EIR should be prepared for the proposed Project to provide additional information and analysis to conclude less-than-significant GHG impacts.
i. SB 375 RTP/SCS Daily VMT Per Capita Target
Under the SCAG’s 2020 RTP/SCS, daily VMT per capita in the SCAG region should decrease from 23.2 VMT in 2016 to 20.7 VMT by 2045.35 Daily VMT per capita in Los Angeles County should decrease from

22.2 to 19.2 VMT during that same period.36 Here, however, the FEIR fails to consider any of the abovementioned performance-based VMT targets. As the FEIR fails to evaluate the Project’s consistency with the SCAG’s performance-based daily VMT per capita projections, the FEIR’s claim that the proposed Project would not conflict with SCAG’s RTP/SCS is unsupported. An updated EIR should be prepared for the proposed Project to provide additional information and analysis to conclude less-than-significant GHG impacts.

Design Features Should Be Included as Mitigation Measures Our analysis demonstrates that the Project would result in potentially significant health risk and GHG impacts that should be mitigated further. We recommend that the FEIR implement all sustainability 34 “Connect SoCal Certified Final Program Environmental Impact Report.” SCAG, May 2020, available at:

As a result, we could guarantee that these measures would be implemented, monitored, and enforced on the Project site. Including formal mitigation measures by properly committing to their implementation would result in verifiable emissions reductions that may help reduce emissions to less-than-significant levels.
