<br />Mud Creek Pit estimate for reclamation Page 3
<br />8,067 CCY = 11,536 CY. Not challenging the push distance and other factors and using
<br />their fleet production of 485.23 LCY/hour, the total job time is reduced from 64.19 hours
<br />to 23.78 hours, and total job cost from $10,721 to $3,971.73.
<br />14. Going on to page 4, DRMS estimates 20 acres to be ripped, but we have no
<br />more than 15 acres, worse case, to be ripped that is NOT in permanent roads: 6 acres
<br />of plant site (8.28 minus 2.28 in permanent roads and buffer zones which were cleaned
<br />up and regarded and done at the beginning of the project), 4 acres of previous pit area,
<br />and 5 acres of freshly disturbed pit area. However, we do not plan to RIP the Mancos
<br />shale floor of the pit (in fact, the objectors were concerned that we would do so!): there
<br />is only the plant site which may need to be ripped: areas which are in process of being
<br />mined MIGHT need to be ripped, so this would provide, at most, 11 acres. Using the
<br />same reduction and accepting their correction factors (whether we agree or not), the
<br />total cost is reduced from $5,160 to $2,838.00.
<br />15. For revegetation, DBMS assumed 20 acres; again, I do not see where this
<br />number came from. In any given year, we have up to 6.0 acres of disturbed plant area:
<br />up to 5.03 acres of last year's mining at final grade but needing reseeding, and up to
<br />5.03 acres of this year's mining and stripping, for a total of 16.06 acres.(Up to 5.03
<br />acres was just reseeded from the previous year's stockpile/work area.) Usually, this
<br />16.06 acres is further reduced by the permanent roads designated. Although this
<br />number is still high, in my opinion, based on the planned sequence of mining and
<br />reclamation, let us accept it for now. This reduces seeding from $12,951 to $10;400.
<br />16. Mobilization (pages 7 and 8) seems to be reasonable.
<br />17. Total for work is now $31,683.00, instead of the $84,470 estimated by the state:
<br />in other words, LESS than my original direct work estimate of $34,161, though
<br />calculated in a completely different way.
<br />18. Using the DRMS standard overhead, with the reduction of the supervisor hours
<br />to 100 (still higher than reasonable, in my opinion), this lowers the total bond amount to
<br />$44,144, which is about $4,000 less than what we originally had.
