Observations for erosion, surface cracks (that might allow LFG <br />to escape or promote air intrusion) and settlement around wells, laterals and main pipelines are <br />conducted. <br />During this reporting period no settlement that might adversely impact (e.g., allow condensate <br />accumulation such that a complete blockage could occur) the LFG collection system operation <br />was observed. <br />STANDARD PROVISIONS <br />This report addresses conditions at the subject site during the reporting period only. <br />Accordingly, we assume no responsibility for any changes that may occur subsequent to our <br />monitoring which could affect the quantity of LFG at the subject site or adjacent properties. The <br />client is responsible for ensuring that SCS and qualified County personnel are the only parties <br />designated to operate and adjust the LFG systems. <br />Should you have any questions, do not hesitate to contact or either of the undersigned. <br />Very truly yours, <br />s <br />Rebecca L.
