<br />^ The biomass typically used for feedstock in this process is plant matter, coal, or natural <br />gas. <br />^ Although MSW may potentially be used as a feedstock, there has been limited research or <br />testing with MSW; and there have been no full-scale facilities developed using MSW as a <br />feedstock. <br />~^® ®~S~A:~/AT'®IVS- AN® ~+®NCLUSI®NS <br />The results of our conversations with representatives of these various organizations, supported by <br />available published literature, were reasonably consistent and in agreement with the 2008 GBB <br />report. These results can be summarized by the following. <br />^ The overwhelming consensus was that mass-burn technology is the only proven <br />technology that is economically viable at this time. <br />^ There is considerable interest at this time in gasification technologies, and a more proven <br />track record with MSW is likely to be tested over the next several years. <br />^ Facilities sized approximately 1000 to 1200 TPD or larger are most likely to be feasible, <br />while facilities smaller than 800 to 900 TPD are not likely to be economically feasible <br />using the best technology. <br />^ A feasible project for Orange County would require a regional facility that imports MSW <br />from surrounding jurisdictions. <br />^ The siting, permitting, and construction costs of a new WTE facility would vary with <br />technology, location, and capacity. However, capital cost estimates based on previously <br />implemented projects range from $150,000 to $300,000 per design TPD capacity - <br />resulting in a $150 million to $360 million facility; <br />^ There have been no successfully implemented WTE projects in the United States for more <br />than 12 years. However, a regional mass-burn facility is being implemented by the <br />NMVUDA that is expected to be 1500 TPD and cost $500 million -equivalent to $333,000 <br />per design TPD capacity. <br />^ Although operating costs vary with technology, typical costs for Orange County are <br />expected to be in excess of $100 per ton, plus hauling and transfer costs unless the WTE <br />facility is sited in Orange County. <br />^ Once a site and project financing are secured and all contracts are final for a facility to be <br />developed, permitting and construction is expected to take approximately four to five <br />years assuming no permitting delays. <br />7 Apri116, 2009 <br />
