4.2.1 EVENT -TRIGGERED CONTINGENCIES Table 4A lists potential event -triggered contingencies. Event -triggered contingencies may include severe rainfall, leachate spill, grass fire, or other sudden, unanticipated events. 4.2.2 INSPECTION -TRIGGERED CONTINGENCIES Table 4B lists potential inspection -triggered contingencies. Inspection -triggered contingencies may include signs of distress in the landfill cover (such as stressed vegetation), cover erosion, leachate head buildup on the liner beneath the waste, surface drainage problems and other findings associated with routine wear and aging of the facility and noticed during routine inspections. 4.2.3 MONITORING -TRIGGERED CONTINGENCIES Table 4C lists potential monitoring -triggered contingencies. Monitoring -triggered contingencies may include contamination of groundwater or surface water beyond action levels, leachate detected in the leak detection systems, detection of methane at gas monitoring points, and other findings discovered as a result of routine facility monitoring. 4.3 Corrective Actions 4.3.1 EMERGENCY ACTIONS Many of the event -triggered contingencies such as natural disasters, vandalism, fire, embankment failure or leachate spill may require an emergency response. Such responses typically need to be implemented immediately and may involve equipment and personnel beyond those routinely involved with facility operation. These additional resources could include city fire and police departments and additional contractor equipment and personnel. Table 4A summarizes, and the following paragraphs describe, the general emergency actions which may be necessary in response to each identified event -triggered contingency. 4.3.1.1 General In the event of emergencies at the site during operations or post -closure, Waste Management personnel must be contacted.
