landfill gas monitoring. Incorporate the evaluation in the MPCA Annual Report for the landfill. (07) VOC Remediation Feasibility Stud¥~ In accordance with MPCA Permit, Part III.C., Corrective Action, the Landfill will be allowed a three-year timeframe in which to demonstrate the effectiveness of landfill gas extraction system in reducing VOC contaminants in the groundwater. Sufficient water quality data, as determined by City Staff, shall be gathered to determine significant trends. If, as of March 1,2001, groundwater quality standards are exceeded at the facility's compliance boundary and the concentration of VOCs do not show a decreasing trend, the Landfill shall complete a Focused Feasibility Study. The Focused Feasibility Study shall be submitted to City staff by June 1, 2001. (08) VOC Remedial Action. If necessary, the selected remedial measure for VOC contaminants identified by the Feasibility Study must be constructed and operational by March 1, 2003, unless good cause can be shown for a delay. (09) Heaw Metal Contaminant MonitorinK and Assessment. Heavy metal contaminants for surface water and groundwater must be addressed in addition to VOC contaminants. Based on the need for additional monitoring to confirm exceedances and identify trends, the Landfill shall continue monitoring and prepare evaluation reports which shall be submitted with the MPCA Annual Reports. (10) .Heavy Metal Contamination Feasibility Study. If heavy metal concentrations in groundwater and surface water exceed regulatory standards, the Landfill will be required to conduct a Feasibility Study and submit it to City staff on schedule determined by City staff. (11) Construction ~)ualit¥ Assurance Reports. A Construction Quality Assurance (CQA) Report shall be submitted to the City prior to the placement of waste on newly constructed lined areas.
