This is a limiting analysis because it does not include other developments that may be expected increasingly to push CCR to beneficial use:<br />
1. Aspects of the proposed CCR rule: This analysis does not take into account that some RCRA regulatory options <strong>for</strong> CCR disposal<br />
require electricity plants to move to dry management of CCR, either through changes to air pollution control strategies or through<br />
drying of CCR after they have been generated. This will make the material more amenable to beneficial uses.<br />
2. <strong>The</strong> analysis is based on current market conditions: It does not take into account new technologies and products now being developed,<br />
<strong>for</strong> example, involving the use of CCR in brick construction. 155 An increased “avoided disposal cost incentive” could be a great boon<br />
to such new beneficial use technologies, applications, and products.<br />
Comparison of “Raw Materials Acquisition Cost Method” to “Travel Cost Method”<br />
<strong>The</strong> method applied above involved three cost components of the “raw material acquisition cost,” not just in relation to the transportation cost<br />
component, which is relatively narrower approach that can be called a “Transportation Cost Method.” Compared to this other method, the raw<br />
material acquisition cost method provides a smaller estimate of effect because the incremental cost is evaluated relative to a broader set of costs<br />
thereby translating numerically into a smaller percentage change, rather than relative to only one cost factor which would translate into a<br />
relatively larger percentage change. This methodological difference may be illustrated by using the calculation numbers applied above, to only<br />
the transportation cost factor. Using a simplistic transportation distance model which uses the CCR disposal unit cost ($ per ton) to determine<br />
the average circular radius of a CCR transportation market between electricity utility plant suppliers of CCR and their beneficial users<br />
customers, the increase in transport distance would be calculated as follows (relative to the 2005 49.6 million tons CCR beneficially used as<br />
reported by the ACAA):<br />
Baseline transportation cost (without CCR rule)<br />
($0.26/mile/ton) x (125 miles one-way average CCR transport distance) x (49.6 million tons/year beneficial use in 2005) = $1,612<br />
million/year transport cost<br />
Hypothetical new transportation cost (with rule)<br />
Transport subsidy equivalency = ($85/ton avoided disposal cost under rule) – ($59/ton avoided disposal cost without rule) = $26/ton<br />
subsidy equivalency<br />
(49.6 million tons/year beneficial use) x ($26/ton subsidy equivalency) = $1,290 million per year subsidy equivalency<br />
Hypothetical new transport distance:<br />
[($1,612 million/year) + ($1,290 million/year)] / (49.6 million tons per year beneficial use) / ($0.26/mile/ton) = 225 miles<br />
Percentage increase in transport distance:<br />
[(225 miles) – (125 miles)] / (125 miles) = 80% increase in radial transport distance<br />
155 Several companies are developing technologies to convert CCR into bricks used in construction, and one such technology was recently commercialized at a power plant<br />
in Wisconsin. Some of these technologies have the potential <strong>for</strong> using 100% CCR (fly ash) in brick production, as opposed to the conventional 30%-50% limit <strong>for</strong><br />
replacing Portland cement in concrete.<br />
