4 Contingency Action Plan 4.1 General This section presents the Contingency Action Plan for the Landfill, prepared in accordance with Part 7035.2615 of the MPCA Solid Waste Rules. In addition to routine landfill contingency responses for the MSW and C&D disposal areas, this Plan also includes responses to events that may occur due to leachate recirculation. The purpose of this plan is to: • Identify occurrences at the facility such as natural disasters, vandalism, accidents or failure of constructed design features that could lead to release of solid waste or leachate and endanger human health and the environment. • Establish the sequence and timing of response actions that would minimize hazards to human health and the environment. • Identify equipment needed to remediate each occurrence. • Identify any possible prior arrangements to be made with contractors in order to assure timely and effective response action. • Estimate the costs associated with these response actions. Section 4.2 identifies potential occurrences, or contingencies, for this facility which may need corrective action. Section 4.3 describes contingent corrective action procedures, including the sequence and timetable, to be followed in case any of the events identified in Section 4.2 take place. Section 4.4 presents action levels for groundwater, surface water and air quality, whichever are included in the monitoring program. Section 4.5 discusses equipment availability. Section 4.6 presents estimated costs for the identified contingency actions. Section 4.7 discusses the need for amendment of this Contingency Action Plan. A copy of this plan will be kept at the Landfill office at all times for reference by on -site and operations personnel as well as regulatory inspection personnel. Each contingency set forth in this plan has a number of possible solutions and no contingency plan can directly address circumstances encountered. Therefore, the MPCA will be promptly notified of major incidents and regular discussions will be held on proposed actions and response status. 4.2 Contingencies That May Need Corrective Action Certain events that may occur at the Landfill could endanger human health or the environment. These events could be the result of natural disasters, accidents, vandalism or failure of constructed design features. Each of the tables listed in the following sections lists contingencies which may be triggered by events, inspections or monitoring, respectively; the possible result, effect, or cause of the contingency; and actions to be taken to evaluate and respond to the contingency.
