RE: Robinson Sons Gravel Pit No. 1, DRMS File# M-2008-076. Second Adequacy
Review of the 112 (c) Construction Materials Application

lvs'
The Division of Reclamationl? inm and Safety has completed its second adequacy
review of your 112 construction materials reclamation permit application and adequacy
review response. The decision date for this application is March 16th, 2009.
The Division has conducted a financial warranty calculation based on the information
provided in your permit application and adequacy review response. The Division
believes the financial warranty for this site, based on an affected area of 20 acres, should
be set at $42,900. This amount is different than the cost estimate submitted in Exhibit L
in the 112 (c) application for several reasons.
First, the cost for spreading overburden and topsoil was based off updated information
about the estimated depths these two materials would be spread over the affected area.
The operator committed to spreading 6-12" inches of overburden over the affected area,
based on this depth and the amount of affected area, the volume of overburden that would
need to be spread was estimated to be 16,133 LCY instead of the original estimate of
10,000 LCY. Also, the operator committed to spreading 4-6" inches of topsoil over the
affected area, based on this depth and the amount of affected area, the volume of topsoil
that would need to be spread was estimated to be 10,755 LCY instead of the original
estimate of 10,000 LCY.
Second, the estimated cost for establishing vegetation over the affected area was higher
than what was submitted in the 112 (c) application. The Divisions estimate for
revegetation consisted of the cost for seed bed preparation, seeding, mulching and an
estimated cost for re-seeding incase of establishment failure. Enclosed with this letter is
a copy of the full cost estimate for the financial warranty, please refer to that document
for more detailed information about calculation.
