<br />Evacuation Plan, and Medical Waste Management Plan) as a condition of approval. Compliance with this requirement
<br />will be verified by the Planning Manager/Designee prior to issuance of building permit or Certificate of Occupancy.
<br /> As discussed, the HVAC system proposed for the teen center/multi-purpose space would be a completely independent
<br />system from all others of the building. The teen center/multi-purpose space would have its own dedicated outside air
<br />system for outdoor ventilation with heating and cooling and would be maintained at a slightly positive pressure with
<br />respect to outside and adjacent lease spaces. For future R&D/Laboratory areas, the proposed HVAC design would
<br />include dedicated air handling units (AHUs) located on the roof supplying 100% outside air to the spaces. According
<br />to the “901 El Camino Real Teen Center, High School and Life Science Program” memo prepared by Meyers+
<br />Engineers (January 28, 2025), the risk of lab exhaust migrating to the teen center/multi-purpose space on the first floor
<br />from a potential future lab program space would be attenuated by the design of the lab exhaust systems with fume
<br />hoods and controls maintaining the lab space under negative pressure relative to adjacent spaces. The risk from lab
<br />exhaust discharge at the roof to the teen center/multi-purpose space on the first floor or to the Sequoia High School
<br />Campus on the other side of El Camino Real (South-West of the proposed project site), would be decreased due to the
<br />distance of the discharge above the roof screen (approximately 110’-0” feet vertical separation), distance from the
<br />high school, and the large amount of dilution that will occur at the roof discharge and beyond. Additionally, as stated
<br />in Section III. Air Quality above, the Commercial component would be subject to Mitigation Measure AQ-3b:
<br />Laboratory Emission Controls which requires the project, once a R&D/Laboratory tenant is identified, to conduct a
<br />health risk screening analysis and obtain a permit from BAAQMD prior to issuance of certificate of occupancy.
<br /> Commercial component compliance with these standard applicable federal, State, County, and local regulations and
<br />City permit conditions would ensure that significant hazards to the public or the environment through the routine
<br />transport, use, or disposal of hazardous materials impacts would be less than significant.
<br /> As a result, this Commercial Component would be consistent with the analysis in the EIR/SEIR because it would not
<br />create new impacts or increase impacts, and there is no new information of substantial importance for CEQA purposes.
<br />b. No manufacturing or industrial processes that utilize or produce dangerous substances are allowed under the DTPP,
<br />and the DTPP program EIR (p. 14-12) concluded that with mandatory local, county, regional, State, and federal
<br />regulations in place, the risk to the public or the environment from upset and accident conditions would represent a
<br />less-than-significant impact. The DTPP Plan-Wide Amendments program SEIR (pp. 14-8 through 14-10) concurred
<br />with the DTPP EIR conclusion and found the impacts related to the accidental release of hazardous materials would
<br />be less than significant. The DTPP Plan-Wide Amendments program SEIR (pp. 14-8 through 14-10) concurred with
<br />the DTPP EIR conclusion. Further, as explained previously in item (a), the DTPP Plan-Wide Amendments “Use
<br />Permit Process” (Sect. 2.2.4) includes several requirements related to reasonably foreseeable upset and accident
<br />conditions related to the project component R&D/Laboratory use:14
<br />A preliminary Biosafety Plan shall be prepared (per California Code of Regulations, Title 8, Division 1, Chapter
<br />4, Subchapter 7, Group 16, Article 109, Section 5199[f][4]) and submitted with the entitlements application,
<br />with a final Biosafety Plan submitted prior to issuance of building permit. [item B)]
<br />A preliminary Evacuation Plan shall be prepared and submitted with the entitlements application, with a final
<br />Evacuation Plan submitted prior to issuance of a building permit. [item C)]
<br />A Medical Waste Management Plan, as applicable, shall be prepared (per the San Mateo County Medical Waste
<br />Program) and submitted with the entitlements application, with a final Medical Waste Management Plan
<br />submitted prior to issuance of building permit. [item D)]
<br /> As discussed previously in item (a), the Commercial Component would involve routine transport, use, or disposal of
<br />hazardous materials, and could result in hazardous emissions, though as explained in item (a), compliance with these
<br />standard applicable federal, State, County, and local regulations and City permit conditions would ensure that
<br />significant hazards would be less than significant. With respect to potential risks from known hazardous materials on
<br />the subject site, the following summarizes the environmental site assessments prepared for the project component:
<br /> Phase I Environmental Site Assessments
<br /> The Commercial Component site was the subject of three site-specific Phase I Environmental Site Assessments and
<br />one separate soil testing to include the various parcels being assembled for the proposed project component: (1) Phase
<br />I Environmental Site Assessment, 901, 947, and 999 El Camino Real, Ramboll US Corporation, August 2019 (“Phase
<br />
<br />14 The project component applicant submitted the following plans to the City for review: “901 El Camino - Preliminary
<br />Biosafety Plan” dated 1/17/25, and “Preliminary Fire Evacuation Plan” dated September 27, 2023, revised August 2, 2024.
