City of Pleasanton–10x Genomics Project Environmental Checklist and Initial Study/Mitigated Negative Declaration Environmental Evaluation FirstCarbon Solutions 89 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480024/ISMND/wp/21480024 10x Genomics Project Full Screencheck ISMND.docx site, and that no on-site dry-cleaning activities, such as use of dry-cleaning machines, is allowed. During the site visit conducted as part of the Phase I ESA, there were no obvious visual indications of past dry-cleaning in the tenant space. Files provided by the LPFD did not contain any information pertaining to dry-cleaning establishments at the project site. In 2016, a letter was submitted by the RWQCB to the property owner at the time (Equity One) that requested information pertaining to the past dry cleaners on the property. There is no indication that Equity One responded to the RWQCB’s request. It is possible that the RWQCB may issue a similar request for information letter to the current and/or future property owner.63 Asbestos sampling completed in 1999 indicated that asbestos was detected in floor tile mastic and vinyl floor tile at the project site. In Spring 2021, the City issued a demolition permit for the site, and required the completion of asbestos and lead based paint and asbestos surveys and abatement, where required, to ensure compliance with State standards prior to the completion of demolition.64 According to the Phase I ESA, two former groundwater wells exist on the project site, although no abandonment records were available, and there were no visible indications of the wells on the project site. If these wells are encountered during project construction, the wells would need to be abandoned in accordance with current guidance, pursuant to MM HAZ-2. Additionally, one existing groundwater monitoring well is located on the site and is monitored semi-annually by Alameda County Flood Control and Water Conservation District - Zone 7. Pursuant to MM HAZ-2, the proposed project would be subject to the requirement to coordinate with Zone 7 to abandon or relocate the well as part of future redevelopment.65 Implementation of MM HAZ-2 would ensure that wells on the project site are abandoned or relocated in accordance with applicable regulations. With implementation of MM HAZ-1 and MM HAZ-2, impacts would be less than significant. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? No impact. The nearest school to the proposed project is the Fountainhead Montessori of Dublin, located 0.67 mile north of the project site. The nearest school within the City of Pleasanton is Lydiksen Elementary School, located 0.76 mile south of the project site. Therefore, the proposed project is not located within 0.25 mile of a school and would not emit hazardous emissions or involve the handling of hazardous or acutely hazardous materials, substances, or wastes within 0.25 mile of a school. Therefore, no impact would occur. 63 EKI Environmental & Water. 2020. Phase I Environmental Site Assessment (ESA). September 24. 64 Ibid. 65 Ibid.
