Hi Jonathan.  The Solid Waste Section (Section) has reviewed your request concerning permanent landfill gas probes 
surrounding Phases 1‐3.  The Section agrees there is no need for permanent landfill gas monitoring wells due to the 
landfill being surrounded by perineal streams.  The landfill gas monitoring plan will include quarterly monitoring of the 
six on site structures.  The Section looks forward to reviewing the Phase 3 expansion Design Hydrogeologic Report.

Hi Elizabeth,

We are currently drafting the Design Hydrogeologic Study and Water Quality Monitoring Plan for a horizontal
expansion (proposed Ph. 3) at the Cleveland Co. Subtitle D Lined Landfill.
However, we are uncertain if Landfill Gas (LFG) migration monitoring probes are necessary since the vast
majority of the property is surrounded by water bodies which the SWS LFG Guidance Document correctly
indicates serve as effective hydraulic barriers to off-site migration. We propose the LFG Plan for Ph. 1,2 & 3
to include only quarterly monitoring of the 6 on-site structures. I've attached a site map showing the pertinent
information including streams that have recently been delineated and approved by the US corps of
Engineers. Please let us know if the SWS would consider approval of a LFG Plan without any probes/wells
and if not what specific areas would probes be required. Simply ask if you need any additional information.

Thank You and have a great weekend,
2
Jonathan
