The City and its contractors will, at a minimum, ensure that: 1. All employees handling fuels and other hazardous materials are properly trained; 2. All equipment is in good operating order and inspected on a regular basis; and 3. Hazardous materials, including chemicals, fuels, and lubricating oils, will not be stored within 200 feet of the tidal slough and other wetland features. This requirement applies to storage of these materials and does not apply to normal operation or use of equipment in these areas. 2.2.1.3 Emergency Spill and Containment Plan In the event of an accidental spill of product from equipment or vehicles, a spill plan will be implemented. The spill plan will be included in the bid specification package and will be present at the work site during all project‐related activities. At a minimum, the City and its contractors will: 1. Ensure that each construction crew (including cleanup crews) has sufficient supplies of absorbent and barrier materials on site to allow the rapid containment and recovery of spilled materials and knows the procedure for reporting spills. 2. Ensure that each construction crew has sufficient tools and material on site to stop leaks. 3. Know the contact names and telephone numbers for the City contacts and local, State, and federal agencies (including, if necessary, the U.S. Coast Guard and the National Response Center) that might need to be notified in the event of a spill. 4. Follow the requirements of those agencies in cleaning up the spill, in excavating and disposing of soils or other materials contaminated by a spill, and in collecting and disposing of waste generated during spill cleanup.
