City of Pleasanton–10x Genomics Project Environmental Checklist and Initial Study/Mitigated Negative Declaration Environmental Evaluation FirstCarbon Solutions 47 Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480024/ISMND/wp/21480024 10x Genomics Project Full Screencheck ISMND.docx Project Operation Land uses typically considered associated with odors include wastewater treatment facilities, waste- disposal facilities, agricultural operations, or other operations listed in Table 11. The proposed project would introduce a new research and development facility that is not expected to produce any offensive odors that would result in odor complaints. During operation of the proposed project, odors would primarily consist of exhaust from passenger vehicles traveling to and from the site. These occurrences would not produce objectionable odors affecting a substantial number of people. Furthermore, as a new research and development facility, the proposed project would not be placing sensitive receptors near existing odor sources. Therefore, operational impacts associated with the project’s potential to create odors would be less than significant. Mitigation Measures MM AIR-1 Implement BAAQMD Best Management Practices During Construction The following Best Management Practices (BMP), as recommended by the Bay Area Air Quality Management District (BAAQMD), shall be implemented during construction: • All active construction areas should be watered at least two times per day. • All exposed non-paved surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and access roads) shall be watered at least three times per day and/or non-toxic soil stabilizers should be applied to exposed non-paved surfaces. • All haul trucks transporting soil, sand, or other loose material off-site shall be covered and/or should maintain at least 2 feet of freeboard. • All visible mud or dirt track-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. • All vehicle speeds on unpaved roads shall be limited to 15 miles per hour. • All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads should be laid as soon as possible after grading unless seeding or soil binders are used. • Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations). Clear signage regarding idling restrictions shall be provided for construction workers at all access points. • All construction equipment shall be maintained and properly tuned in accordance with manufacturer’s specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. • The prime construction contractor shall post a publicly visible sign with the telephone number and person to contact regarding dust complaints. The City of Pleasanton and the construction contractor shall take corrective action within 2 business days. The BAAQMD’s phone number shall also be visible to ensure compliance with applicable regulations.
