Specifications include, but are not limited to: Routine Scheduled Maintenance: Conduct a routine scheduled site visit every two months for a total of 18 visits in a thirtysix month period. Check the operation and maintenance of the blower/flare station during each visit o Damage and noticeable operational deficiencies will be noted o Gas quality measurements will be taken at the main gas header/and or the flare inlet using a Landtec GEM landfill gas analyzer or other appropriate landfill gas analyzer o Provide description of any major issues with the blower/flare station o Make changes to the flare operation schedule for optimal operation based on landfill gas production. Collect the following data during each site visit: o Landfill gas flow o Landfill gas composition (percentages of methane, carbon dioxide, oxygen and balance gases) o Main inlet header vacuum o Flare temperature Conduct scheduled maintenance in accordance with the Perennial Energy Operation & Maintenance Manual for a 13.5 MMBtu/h Enclosed Gas Flare Station for the Flanders Road Landfill (April 2002) Maintenance Schedule. Note: The Department will perform the daily checks indicated in Maintenance Schedule. Prepare a brief letter report monthly, detailing activities occurring each month including daily flare operations from the Department’s weekly checklist report. The letter report shall include temperature and flow readings of the flare and Criteria Pollutant Emissions Calculations: calculated flare stack emissions of particulate matter (PM), sulfur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) as non-methane organic compounds (NMOC), and carbon monoxide (CO) as compared to the allowable limits in the Flanders Road Landfill Modified Permit for Municipal Solid Waste Landfill Gas Collection and Control System dated January 2, 2013. The letter report shall also include monthly and annual volumetric landfill gas flow rate to the enclosed flare and annual emissions calculated over a rolling 12-month period for the Criteria Pollutant Emissions Calculations as required in the Modified Permit. Each letter shall be submitted to the Department within 30 days of the end of the previous month to meet the record keeping requirement in the Modified Permit.
