(02) Backup Leachate Pumps. Licensee shall maintain a backup pump for use <br />in the event of pump failure at the Leachate sump, wet well and/or Leachate storage <br />tank on-site. As an alternative, the licensee shall maintain provisions for restoring <br />temporary Leachate pumping within a 24-hour period and adhere to the current <br />"Leachate Management Plan" as approved by MPCA. <br />(03) Leachate Holding Tank. Licensee shall ensure that the Leachate holding. <br />tank is pumped out on a regulaz schedule. It shall be a violation of this License to <br />allow Leachate to collect on the liner to a depth exceeding one foot due to the <br />Leachate holding tank being full. <br />(04) Gas Venting System. Licensee shall conduct acfive landfill gas venting in <br />accordance with approved plans and shall construct additional phases of the active <br />gas control system at the time of final cover construction. <br />(OS) Phase IV Water Ouality Monitoring Work Plan. The Phase IV Water <br />Quality Monitoring Work Plan which describes the sampling frequency, <br />pazameters, protocols and reporting frequency for landfill gas, Leachate, Leachate <br />piezometers, Leachate lysimeters, residential wells, groundwater monitoring wells <br />and surface water shall be updated annually to reflect changes in the monitoring <br />systems. The monitoring plan shall yield adequate information for assessing the <br />effectiveness of the landfill gas control system in decreasing VOC contaminants <br />in the groundwater. <br />(06} Annual Active Landfill Gas Control System Assessment. Annually assess <br />the effectiveness of active landfill gas venting operations based on the results of <br />groundwater and landfill gas monitoring and incorporate the evaluation in the <br />MPCA Annual Report for the landfill. <br />(07) Heavy Metal Contaminant Monitoring and Assessment. Heavy metal <br />contaminants for surface water and groundwater must be addressed in addition to <br />VOC contaminants. Based on the need for additional monitoring to confirm <br />exceedances and identify trends, the Landfill shall continue monitoring and <br />prepaze evaluation reports which shall be submitted with the MPCA Annual <br />Reports. <br />(08) Heaw Metal Contamination Feasibility Study.
