No. OC & Waste Recycling needs data from the instantaneous prior to allowing the

contractor to conduct integrated monitoring.

21.) Please provide maps showing locations of probes relative to the landfill footprint.

Maps will be provided by November 29, 2011

22.) Are historical probe monitoring results available? (This may help quantify how much ISM

(SEM?) will be needed between probes that regularly show 2% or more methane and the LF

footprint)

Yes. The probe results are available and will be provided through Bidsync by

November 29, 2011

23.) If ISM is required between probes and the landfill footprint, is this considered an emergency

task? What actions is the contractor required to take should ISM be required between probes and

the LF footprint and in accordance to which regulation?

Integrated Surface Monitoring typically will not be required between probes and

landfill footprint. If required, OC Waste & Recycling will request a task proposal

from the contractor; protocols governing regulations will be determined if a Task

Order is issued.
