The certification, shall be prepared and signed by the owner or operator of the landfill, certified facility manager, solid waste manager or person most directly responsible for the landfill's day to day operation. The signer shall certify that he or she is aware of all approved plans for the landfill, all department conditions of approval, and all applicable solid waste statutory and administrative rules, and that to the best of the signer's knowledge, information and belief, the landfill is or is not in substantial compliance with all approved plans and requirements.

(e) An evaluation of the performance of the leachate collection and removal system which shall include graphed results of monthly leachate removal volumes from the beginning of filling at the landfill to the end of the current calendar year. Leachate volume data shall be graphed separately for each leachate collection tank or lift station. Leachate removal volumes shall also be graphed as a depth over the area of liner which has been constructed at a given point in time. Graphs shall note when each phase or portion thereof was constructed or closed. Monthly leachate data shall be annualized by multiplying by 12 and reported in units of inches per year. All leachate quality data for BOD or COD, including that regularly performed at the request of wastewater treatment facilities, shall be presented graphically. Graphs of monthly average BOD or COD in mg/l shall be presented as well as pounds of BOD or COD removed per month from the facility. Also included shall be a tabulation of all past monthly leachate removal volumes and average BOD or COD concentrations.
NR 506.19(2)(f)
(f) Graphs of leachate head conditions on the liner and trends with time shall be reported. Where lysimeters or gradient control systems are present under the liner, fluid collection quantity and quality data shall also be tabulated.
NR 506.19(2)(g)
(g) Graphs and tables evaluating the performance of the gas extraction system over the previous 3 years including: the volume of gas removed and average methane concentration to be presented on a no less frequent basis than quarterly; the condition of each gas extraction well and identification of any wells which need to be replaced or that have been replaced; a summary of the hours of operation and down time of the gas recovery plant or blower; and a summary of any exceedances of the lower explosive limit of any gasses detected in gas monitoring wells located outside the limits of waste. This information shall also be presented graphically to the extent possible.
