water shall be updated annually to reflect changes in the monitoring systems. The <br />monitoring plan shall yield adequate information for assessing the effectiveness of <br />the landfill gas control system in decreasing VOC contaminants in the <br />groundwater. The annual updates shall be approved by the City. <br /> <br />(06) Annual Gas Vent System Assessment. Annually assess the effectiveness <br />of active landfill gas venting operations based on the results of groundwater and <br />landfill gas monitoring and incorporate the evaluation in the MPCA Annual <br />Report for the landfill. <br /> <br />(07) VOC Remediation Feasibility Study. In accordance with MPCA Permit, <br />Part III.C., Corrective Action, the Landfill will be allowed a three year timeframe <br />in which to demonstrate the effectiveness of landfill gas extraction system in <br />reducing VOC contaminants in the groundwater. Sufficient water quality data, <br />as determined by City Staff, shall be gathered to determine significant <br />trends. <br /> <br />If, as of March 1, 1999 2001, groundwater quality standards are exceeded at the <br />facility's compliance boundary and the concentration of VOCs do not show a <br />decreasing trend, the Landfill shall complete a Focused Feasibility Study. The <br />Focused Feasibility Study shall be submitted to City staff by June 1, 1999 2001. <br /> <br />(08) VOC Remedial Action. If necessary, the selected remedial measure for <br />VOC contaminants identified by the Feasibility Study must be constructed and <br />operational by March 1, 2001 2003, unless good cause can be shown for a delay. <br /> <br />(09) 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 />prepare evaluation reports which shall be submitted with the MPCA Annual <br />Reports. <br /> <br />(10) Heavy Metal Contamination Feasibility Study. If heavy metal <br />concentrations in groundwater and surface water exceed regulatory standards, the <br />Landfill will be required to conduct a Feasibility Study and submit it to City staff <br />on a schedule determined by City staff. <br /> <br />(11) Construction Quality Assurance Reports. A Construction Quality <br />Assurance (CQA) Report shall be submitted to the City prior to the placement of <br />waste on newly constructed lined areas. A CQA report shall also be submitted for <br />Landfill areas which receive final cover. The report shall demonstrate that the <br />work is completed to the plan specifications. The Report shall be certified to by <br />an engineer registered in the State of Minnesota and shall include but not be <br />limited to: <br /> <br />10 <br /> <br /> <br />
