Dear Ms. Wilburn:

The North Carolina Solid Waste Section (SWS) is presently conducting a technical review of
two (2) landfill gas monitoring plans you submitted on June 29, 2012, on behalf with the closed
landfills mentioned above.

Revise the Germantown Landfill Gas Monitoring Plan, Page 2, table for “Proposed Monitoring
Well Summary” by adding GW-4 and well construction criteria to the list.

Revise both landfill gas monitoring plans by adding the following conditions:

1. Within ninety (90) days of approval of the landfill gas monitoring plan by the Solid
Waste Section (SWS), the new gas monitoring wells shall be installed at the proposed
locations as depicted on the site drawings.

2. A Professional Engineer (P.E.) or a N.C. Professional Geologist (L.G.) must certify/
supervise the installation of all landfill gas monitoring wells.

3. Each constructed landfill gas monitoring well must be surveyed for location and
elevation by a North Caroling Registered Land Surveyor.

4. Within thirty (30) days of completion of the landfill monitoring gas wells, a well
construction record and/or boring log and a diagram for each well, including but not
limited to total depth, screened interval and distance above seasonal table must be

submitted to the SWS. The submittal must also include a scaled topographic map
showing the surveyed location and identification of new, existing and abandoned
landfill gas monitoring wells.

Both revised landfill gas monitoring plans must be signed, sealed, and dated by a N. C.
Professional Engineer (P.E.) or a N.C. Professional Geologist (L.G.) and submitted the SWS
section for approval within thirty (30) days of the date of this letter. Once approved by the SWS,
construction of gas monitoring wells/reporting criteria and subsequent sampling of gas
monitoring wells may commence according to the gas monitoring plans.
