Summary of 2018 Spotorno Ranch Air Quality Analysis March 22, 2021 Page 11 of vehicles travelling to and from the site. These occurrences would not produce a significant number of odors; therefore, odors generated from project operations would be less than significant. Air Quality Mitigation MM AIR-2 During construction, the following air pollution control measures shall be implemented: • Exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day, or more as needed. • All haul trucks transporting soil, sand, or other loose material off-site shall be covered • 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 and surfaces shall be limited to 15 miles per hour. • All roadways, driveways, and sidewalks shall be paved as soon as possible. • 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 [CCR]). Clear signage 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. • A publicly visible sign shall be posted with the telephone number and person to contact both at the City of Pleasanton and at the office of the General Contractor regarding dust complaints. This person shall respond and take corrective action within 2 business days of a complaint or issue notification. The BAAQMD’s phone number shall also be visible to ensure compliance with applicable regulations.
