Secondary containment will be provided for any equipment or vehicles stored in the work area to reduce the potential for any spills. 2. All fuel required by construction equipment will have primary and secondary containment. Any spills will be contained and properly disposed of according to permit requirements. 3. All vehicles and equipment will be properly maintained to reduce the potential for spills of petroleum‐based products. Containment booms and sorbent materials will be available during work activities and will be deployed immediately in the event of a spill to limit its spread. 4. No debris, soil, silt, sand, cement, concrete, or washings thereof, or other construction‐related materials or wastes, oil or petroleum products, or other organic or earthen material will be allowed to enter into or be placed where it may be washed by rainfall or runoff into the tidal slough. 5. If any materials or wastes are accidentally released into the slough, project supervisors will immediately halt all work and utilize all available resources to ensure containment and removal. 6. Necessary steps will be implemented to ensure the health and safety of the workers on the job and public in the surrounding area. The crew and supervisors will be trained with all documentation current and environmental and security regulations precisely followed. 7. BMPs will be consistently employed to help prevent pollutants from entering the slough. Employees, subcontractors, and vendors must be informed, educated, and trained to understand the applicable practices and procedures for the various construction activities being performed. 8. After construction is completed, final cleanup of the project area will include removal of all refuse generated by construction that will be placed into trucks for proper disposal. In addition, all equipment will be safely demobilized from the area. 9. The City will schedule as much work as possible during the dry season to minimize the potential for wet weather, surface flooding, and high water tables in the work area. 10. Pets will not be allowed in or near the work site. 11. Firearms will not be allowed in or near the work site. No intentional killing or injury of wildlife will be permitted. 12. The work site will be maintained in a clean condition. All trash (e.g., food scraps, cans, bottles, containers, wrappers, cigarette butts, and other discarded items) will be placed in closed containers and properly disposed of off‐site.
