SCOPE OF SERVICES <br /> Task 1 Initial Landfill Inspection <br /> 1 . 1 At the time of acceptance of the Landfill gas <br /> collection system by the District and Contractor notice to <br /> proceed , Contractor will conduct an initial inspection of <br /> the Landfill gas system . This inspection will take 2 to 3 <br /> days and will include the first routine operation and <br /> maintenance ( hereinafter " O &M " ) visit as well as : <br /> 1 . 1 . 1 . Assessment of above - grade piping and wellhead <br /> integrity ; <br /> 1 . 1 . 2 . Thorough review of the flare operation , including <br /> blower function ; <br /> 1 . 1 . 3 . Documentation of the current flow through the <br /> system ; <br /> 1 . 1 . 4 . Calculation of the system heat content ( Btu ) ; and <br /> 1 . 1 . 5 . Evaluation of the integrity of each probe . <br /> 1 . 2 . In addition , Contractor will take digital <br /> photographs of the flare skid and wells and collect <br /> baseline samples from each of the proposed 47 gas <br /> monitoring locations , including the probes . The available <br /> vacuum applied at each well , the gas flow and gas quality <br /> ( CH4 , CO2 , 02 , and / or N2 ) will be recorded and we will <br /> determine whether there is adequate vacuum being applied <br /> across the wellfield . A written report will be prepared <br /> for the District ' s file and this baseline data will be used <br /> to compare future operation of the gas system . <br /> 1 . 2 . 1 . It is assumed construction logs and as - builts for <br /> the gas system will be provided in electronic format , if <br /> available , or hardcopy , if not . The construction logs must <br /> show the well depth , length of the screened interval , <br /> boring diameter , and casing diameter . <br /> Task 2 - Routine Monitoring and Maintenance <br /> 2 . 1 . General . For a non - NSPS operations and maintenance <br /> visit , Contractor will conduct a one ( 1 ) day routine <br /> system - wide inspection and data collection , consistent with <br /> normal procedures for such systems . The methane and oxygen <br /> concentrations and gas flow rates ( if wellhead <br /> configuration allows ) of the gas wells will be monitored <br /> and adjusted to minimize offsite migration , e . g . overdraw <br /> and to maximize LFG collection . <br /> 12 <br />
