In the site-wide reclamation cost estimate(RCE)recently completed with the approval of Permit
<br /> Renewal 07 (RN-07)the reclamation of sites included in the SL-14 application is accounted for in tasks
<br /> 423a,427a, 427b,428a,428b,429a,429b and 441 (all of which also include sites that are not addressed
<br /> with SL-14);these tasks will need to be reconciled when the next site-wide RCE is calculated. The pro-
<br /> rated total of the estimated direct costs associated with these tasks (Y)is $146,798.23,as shown in table
<br /> 4.

<br /> 423b Lick Creek Portal Investigation Holes A-F, regrade $10,106.00
<br /> 427a 7 E-seam MVBs panels 2-6, plug and seal $24,409.00
<br /> Task 427a pro-rated for 1 of 7 MVBs $3,487.00
<br /> 427b 7 E-seam MVBs panels 2-6, backfill and regrade $35,016.00
<br /> Task 427b pro-rated for 0.81 of 6.93 acres $4,092.78
<br /> 428a 12 E-seam MVBs panel 7, plug and seal $41,839.00
<br /> Task 428a pro-rated for 8 of 12 MVBs $27,892.67
<br /> 428b 12 E-seam MVBs panel 7, backfill and regrade $41,433.00
<br /> Task 428b pro-rated for 6.99 of 8.2 acres $35,319.11
<br /> 429a 8 E-seam MVBs panel 8, plug and seal $27,886.00
<br /> Task 429a pro-rated for 6 of 8 MVBs $20,914.50
<br /> 429b 8 E-seam MVBs panel 8, backfill and regrade $36,056.00
<br /> Task 429b pro-rated for 4.25 of 7.14 acres $21,461.90
<br /> 441 33 Monitoring wells: plug and seal $80,380.00
<br /> Task 441 pro-rated for 3 of 33 Monitoring wells $7,307.27
<br /> Total applicable to SL-14 $146,798.23
<br /> In order to (i) comply with rule 3.03.1(2) and(ii) ensure that the revised required surety is
<br /> sufficient to cover the remaining reclamation liability at the mine,the Division will release
<br /> whichever is the smaller of the two values X and Y. In this case,the smaller value,Y,is
<br /> $146,798.23.
<br /> The Division currently holds a performance bond of$15,000,000. Based on the observations above,the
<br /> Division proposes to release $146,798.23. Following the approval of SL-14 the revised required surety
<br /> will be $11,756,466.23,which is sufficient to assure completion of the remaining reclamation work at
<br /> the site if the work had to be performed by the Division,including the cost of reestablishing vegetation
<br /> on any revegetated areas, should those areas fail. The Division estimates its cost to complete remaining
<br /> reclamation work at the site to be $11,756,466.23.
