9 <br />(c) If ambient concentrations of landfill gas identified during the <br />NSPS surface scans exceed 500 ppm explosive gas (calibrated to <br />methane), corrective actions are required to amend the landfill <br />cover to mitigate fugitive emissions. This requirement is important <br />in identifying fugitive gas emissions/odors and ensuring that site <br />conditions are corrected to mitigate their effects. <br /> <br />(06) Sampling and Analysis Plan. The Sampling and Analysis Plan, which <br />describes the sampling frequency, parameters, protocols and reporting frequency <br />for landfill gas, leachate, leachate piezometers, leachate lysimeters, residential <br />wells and groundwater monitoring wells shall be assessed annually to reflect <br />changes in the monitoring systems. The Plan shall yield adequate information for <br />assessing the effectiveness of the landfill gas control system in decreasing VOC <br />contaminants in the groundwater. The proposed compliance boundary within the <br />Plan is not approved because it incorporates City property inside the compliance <br />boundary. The compliance boundary will be limited to the Landfill Property. <br />Corrective actions (potentially associated with contaminant migration) on City <br />property, which potentially limit the use of City property, are not allowed. <br /> <br />(07) Annual Operating Report. An Annual Operating Report shall be submitted <br />with the following supplemental items. <br /> <br />(a) Annual Waste Disposal Volume. <br /> <br />(b) Schedule of construction activities for the forthcoming year. <br /> <br />(c) Type and Quantity of Material Disposed. <br /> <br />(d) Remaining permitted capacity <br /> <br />(e) Updated, high resolution, contour map which indicates the <br />elevations of all fill areas <br /> <br />(f) Assessment of the Financial Assurances Plan. <br /> <br />(g) Evaluation of the Water Monitoring System and a proposal for <br /> continued sampling and analysis. <br /> <br />(h) Detailed evaluation of all water quality results by means of tables <br /> and graphs. <br /> <br />(i) A groundwater contour map based on the previous years’ <br /> groundwater level data. <br /> <br />(j) Assessment of the effectiveness of active landfill gas control <br />operations based on the results of groundwater and landfill gas
