<br />geomembrane final cover), including final cover vegetation. The analysis assumed an average
<br />closure cost of approximately $126,000/acre for both scenarios. The estimated closure costs for
<br />a 20-acre, Town-only landfill would be approximately $2.5 million, and for the 50-acre regional
<br />landfill of $6.3 million. Amortized over 30 years at 4%, these capital costs would represent an
<br />annual cost of $146,000/year and $364,000, respectively.
<br />The annual post-closure care costs for the two landfill scenarios were estimated. Post-closure
<br />would be required for a minimum of 30 years. SCS estimated the 30-year post-closure care costs
<br />to the two scenarios to be $3.6 million and $5.2 million, respectively, with an estimated annual
<br />accrual of approximately $120,000 and $172,000, respectively. The post-closure care activities
<br />include maintaining the final cover system and other environmental control systems (landfill gas,
<br />leachate, and stormwater), and environmental monitoring.
<br />11.1.6 Summary of Landfill Development, Operations, Closure,
<br />and Post -Closure Costs
<br />Exhibit 11-9 presents a summary of the estimated costs to develop, operate, close, and provide
<br />for post-closure care for the Town-only and regional landfill scenarios. This exhibit
<br />demonstrates the importance of economies of scale in developing and operating a landfill. As
<br />depicted in the exhibit, operating a Town-only landfill would be cost prohibitive on a dollar per
<br />ton basis, while the total estimated cost for the regional landfill scenario is similar on a dollar per
<br />ton basis to what the Town currently is paying for disposal at the Orange County Landfill.

<br />11.1.7 Conclusion and Recommendations
<br />As noted above, siting and developing a new Town-only landfill would be difficult for a number
<br />of reasons and cost prohibitive due to economies of scale. Developing a new regional landfill
<br />provides for better economies of scale, but would face the same difficulties regardless of where it
<br />is located in the region. SCS does not recommend that the Town pursue developing its own
<br />landfill, but continue to participate in potential future regional cooperative efforts in this regard.
