<br /> outlined in the PC Permit. Reduced costs in 2034 assumes monitoring and
<br /> reporting of POC wells annually under Detection Monitoring.
<br /> Treatment system will operate for the duration of the post closure permit
<br /> 3. TREATMENT SYSTEM O&M (10 years), through 2027. Assumes pulsing of treatment system every $1,421,020 $142,102 $142,102
<br /> quarter; thus, treatment system operates 6 months of the year.

<br /> 5. COVER AND DRAINAGE SYSTEM MAINTENANCE $24,000 $800 $800
<br /> include observations regarding subsidence, and any changes to topography
<br /> and/or surface water drainage.
<br /> Cost related to O&M of treatment system are captured in Task 3. Well
<br /> redevelopment and repair costs are calculated based on GWM during post
<br /> 6. MONITORING, COLLECTION AND DISPOSAL SYSTEM MAINTENANCE corrective action measures period as that is when the most number of wells $271,076 $11,999 $11,999
<br /> will be sampled. Costs during corrective action measures period and
