1 Memorandum To: Kevin Johnson Design & Historic Preservation Section City of Pasadena Planning & Community Development Department From: Rusty Whisman and Terrance Wong, ICF CC: Charles Smith and Tamseel Mir, ICF Date: April 4, 2018 Re: Summary of Air Pollutant Emissions Modeling for the S Euclid Mixed-Use Development The purpose of this memorandum is to summarize the results of the air pollutant emissions modeling undertaken for the proposed mixed-use development at S Euclid Avenue. The proposed project would involve the demolition of an existing office building at 10 S. Euclid Avenue and the construction of a new five-story, mixed-use structure with 1,000 square feet of office space, 42 residential condominium units, and parking spaces within one ground level and one subterranean-level parking garage. The existing two-story mixed-use building at 180 S. Euclid Avenue would be relocated in the spring of 2018 as part of a separate effort prior to the start of construction of the proposed project. Short-term construction and long-term operational pollutant emissions generated by the proposed project were modeled using the California Emissions Estimator Model (CalEEMod), Version The modeling that was performed was based on project-specific data provided by the applicant, where available. Where project-specific information was not available, default model settings were used to estimate criteria air pollutant and ozone precursor emissions. Because it is mandatory for all construction projects in the South Coast Air Basin to comply with South Coast Air Quality Management District (SCAQMD) Rule 403 for fugitive dust control, the reduction of fugitive particulate matter 10 microns or less in diameter (PM 10 ) and particulate matter 2.5 microns or less in diameter (PM 2.5 ) emissions from implementation of Rule 403 was accounted for in the modeling. Specific Rule 403 control requirements include, but are not limited to, applying water to exposed soils, particularly during grading activities; washing equipment and vehicles or using another other method for removing material (e.g., washed gravel pad, wheel shaker, wheel spreading device) prior to leaving the project site; covering haul loads prior to haul vehicles leaving the project site; and removing any accumulated dirt/mud from roadways adjacent to the project site. The resulting short-term construction and long-term operational emissions estimated using CalEEMod were then compared to SCAQMD s applicable daily regional mass emissions thresholds and localized significance thresholds (LSTs) to determine the project s effect on air quality. This memorandum is divided into sections summarizing short-term construction emissions and longterm operational emissions, with regional mass emissions and localized emissions discussed in each section. The modeling output files are provided in Attachment 1 to this memorandum.

2 Summary of Air Pollutant Emissions Modeling for the S Euclid Mixed-Use Development April 4, 2018 Page 2 of 6 Project Construction Regional Emissions Construction associated with the proposed project would generate pollutant emissions from the following activities: (1) demolition, grading, and excavation; (2) construction workers traveling to and from project site; (3) delivering construction supplies to, and hauling debris from, the project site; (4) fuel combustion by on-site construction equipment; and (5) building construction and the application of architectural coatings. These construction activities would temporarily create emissions of dust, fumes, equipment exhaust, and other air pollutants. The amount of emissions generated on a daily basis would vary, depending on the intensity and types of construction activities occurring simultaneously. Construction of proposed project is anticipated to commence in May 2019 and conclude in September Construction activities would occur between the hours of :00 a.m. and 5:00 p.m. Monday through Friday. Table 1 shows the project s construction phases and the estimated durations of each phase. Table 1. Anticipated Project Construction Schedule Phases Start (month/date/year) Finish (month/date/year) Duration (work days) Demolition 05/01/ /14/ Grading 0/01/2019 0/19/ Building Construction 0/23/ /01/ Architectural Coating 04/01/ /0/ Construction would require demolition of the existing one-story office building at 10 S Euclid Avenue (the two-story mixed-use building at 180 S. Euclid Ave would be partially demolished and partially relocated as part of a separate effort prior to the start of construction of the proposed project in the spring of 2018). The removal of this debris is estimated to require approximately 25 haul truck trips during the 10-day demolition phase. Additionally, an estimated 13,932 cubic yards of soil would need to be excavated and exported from the site, requiring an estimated 1,42 haul truck trips in total, and approximately 11 haul truck trips per day during the grading phase. Table 2 summarizes the modeled peak daily emissions of criteria air pollutants and ozone precursors associated with construction of the proposed project. As shown, the maximum level of daily construction emissions generated by the proposed project would not exceed SCAQMD s daily significance thresholds for any criteria pollutants during any of the construction phases. Therefore, construction-phase emissions would have a less-than-significant impact related to regional air quality.

No No No No No No Source: CalEEMod modeling output provided in Attachment 1. Note: Emissions would be slightly different during the summer and winter seasons. Emission levels of ROG and NOX tend to be higher during the winter, while emissions of CO and SOX tend to be generally higher in the summer. Emissions of and remain the same during both seasons. The maximum emissions for each pollutant over the course of the summer and winter seasons are shown in this table. The building construction and architectural coating phases would overlap in 2020, and emissions for each phase have been added together. ROG = reactive organic gases NOX = nitrogen oxides CO = carbon monoxide SOX = sulfur oxides = particulate matter less than 10 microns in diameter = particulate matter less than 2.5 microns in diameter

4 Summary of Air Pollutant Emissions Modeling for the S Euclid Mixed-Use Development April 4, 2018 Page 4 of 6 Localized Emissions To assess the potential localized air quality impacts resulting from the project on nearby sensitive receptors during construction, the daily on-site construction emissions generated at the project site were evaluated against SCAQMD s applicable construction LST screening thresholds for a 1-acre site. Although the site is 0.52 acres in size, the LST screening thresholds for a 1-acre site were used, as a one-acre site is the smallest site identified in the LST mass look-up table. The nearest sensitive receptors to the project site that may be exposed to localized air quality impacts include the multifamily residential uses to the north and the multi family residential uses and Sheraton Pasadena Hotel to the west, across South Euclid Avenue. The multi-family residential uses to the north of the project site are located adjacent to the property line, while the multi-family residential uses and Sheraton Pasadena Hotel are located approximately 80 feet away from the project site s property line. Because the SCAQMD mass rate look-up tables provide only LST screening thresholds at receptor distances of 25, 50, 100, 200, and 500 meters, the LSTs for a receptor distance of 25 meters were used to evaluate the potential localized air quality impacts associated with the project s peakday construction emissions. 1 Table 3 presents the unmitigated localized on-site emissions that are estimated to occur during peak construction days for each year of the project s construction schedule. As shown in Table 3, the daily unmitigated emissions generated on-site by construction of the proposed project would not exceed any of the applicable SCAQMD LST screening thresholds for a 1-acre site in SRA 8 over the course of the entire construction schedule. Thus, the localized construction air quality impacts of the project would be less than significant. Table 3. Localized Criteria Pollutant Construction Emissions (Unmitigated) Construction Year Estimated Maximum Daily On-site Emissions (pounds per day) NOX CO LST Screening Thresholds a Threshold Exceeded? No No No No Source: CalEEMod modeling output provided in Appendix A. a Construction LSTs for a 1-acre site in SRA 8 (West San Gabriel Valley) at a 25-meter distance for sensitive receptors. Notes: 1. Emissions would be slightly different during the summer and winter seasons. The maximum emissions for each pollutant over the course of the summer and winter seasons are shown in this table. 2. An electric-powered jackhammer would be used during the demolition phase. Due to its power source, no emissions from fuel consumption would occur, and the equipment emissions were not modeled. Use of the jackhammer could generate a small amount of fugitive dust, but such emissions would be negligible and have not been quantified. NOX = nitrogen oxides CO = carbon monoxide = particulate matter less than 10 microns in diameter = particulate matter less than 2.5 microns in diameter 1 According to SCAQMD s LST methodology, it is recommended that projects with boundaries closer than 25 meters from the nearest receptor use the LSTs for receptors located at 25 meters.

5 Summary of Air Pollutant Emissions Modeling for the S Euclid Mixed-Use Development April 4, 2018 Page 5 of 6 Project Operations Regional Emissions Implementation of the proposed project would result in long-term regional emissions of criteria air pollutants or ozone precursors associated with area sources, such as natural gas consumption, landscaping activities, applications of architectural coatings, and use of consumer products, in addition to operational mobile emissions. According to the Transportation Impact Analysis prepared by the City of Pasadena for the project, development of the proposed project would result in a net increase in the number of vehicle trips per day (i.e., 250 trips) when compared with the existing baseline condition at the project site. Table 4 presents daily operational emissions generated by the project compared with existing conditions. As shown in Table 4, the proposed project would result in long-term regional emissions of criteria air pollutants and ozone precursors that would be below SCAQMD s applicable thresholds. Therefore, the regional air quality impact of the project s operational emissions would be less than significant. Table 4. Proposed Project Criteria Pollutant Operational Emissions (Unmitigated) Source Proposed New Residences Pollutant Emissions (pounds per day) ROG NOX CO SOX Area Sources < Energy Sources < Mobile Sources Project Emissions Regional Significance Thresholds Threshold Exceeded? No No No No No No Source: CalEEMod modeling output provided in Appendix A. Notes: Emissions would be slightly different during the summer and winter seasons. Emission levels of ROG and NOX tend to be generally higher during the winter, while emissions of CO and SOX tend to be generally higher in the summer. Emissions of and remain the same during both seasons. The maximum emissions for each pollutant over the course of the summer and winter seasons are shown in this table. operational emissions for the proposed project do not take into consideration the existing uses present at the site, and therefore overstate the air quality impacts of the project. Emissions identified above would be at least partially offset by the reduction in emissions from the demolition of existing uses at the project site. ROG = reactive organic gases NOX = nitrogen oxides CO = carbon monoxide SOX = sulfur oxides = particulate matter less than 10 microns in diameter = particulate matter less than 2.5 microns in diameter

6 Summary of Air Pollutant Emissions Modeling for the S Euclid Mixed-Use Development April 4, 2018 Page 6 of 6 Localized Emissions Similar to the analysis of construction emissions, the daily localized pollutant emissions generated on-site by the project during operations was also assessed for its potential localized air quality impacts on nearby sensitive receptors. On-site were compared to SCAQMD s applicable operational LST screening thresholds for a 1-acre site. Table 5 presents the project s on-site operational emissions. As shown, the project s long-term operational emissions generated on-site would not exceed SCAQMD s applicable operational LST screening thresholds. Thus, localized air quality impacts during project operations would be less than significant. Table 5.

No No No No Source: CalEEMod modeling output provided in Appendix A. a Operational LSTs for a 1-acre site in SRA 8 (West San Gabriel Valley) at a 25-meter distance for sensitive receptors. Note: Emissions would be slightly different during the summer and winter seasons.

Emissions identified above would be at least partially offset by the reduction in emissions from the demolition of existing uses at the project site. On-site emissions were estimated by adding area, energy, and ten percent of the mobile emissions (to account for vehicle travel and idling at the site). NOX = nitrogen oxides CO = carbon monoxide = particulate matter less than 10 microns in diameter = particulate matter less than 2.5 microns in diameter
