The Division has reviewed your July 31, 2002 response to previous adequacy concerns of the Division regarding
the above referenced amendment application. Tn order to achieve a decision of approval for your application, you
will need to address the remaining concerns listed below to the satisfaction of the Division. As you may know,
the decision date for your amendment application has been revised to August 23, 2002. Therefore, we would
appreciate a response from you on or before August 19, 2002 to allow adequate time for review.
6.4.5 EXHIBIT E -Reclamation Ptan
11. It appears that Albert Frei & Sons, Inc.'s {AFSI) intent is to construct several water storage reservoirs at the
Walstrvm Quarry at some time in the future. However, design documents and other information pertaining io
reservoir adequacy concerns wiIl be addressed via a separate permit modification. Since there is a fair amount of
discussion in the mine plan and reclamation plan pertaining to the reservoir construction, and page 4 (item IS) of
the amendment application form states "The request also includes two water storage reservoirs ..." the Division
requests that the operator clarify that construction of the reservoirs, associated reclamation costs, and end land use
for such areas as developed water resources should not be considered a part of this amendment application. Also,
Exhibit F -Reclamation Plan Map will need to be revised to show two (2) depressions for indushiaUcommercial
use rather than 2 lakes. In the event that groundwater is encountered during excavation at the quarry, AFSI will
need to notify the Division within 48 hours and should be prepazed to provide a written demonstration of
adequate water rights or approvals as required by the Office of the State Engineer. An alternative to such
notification would be for AFSI to commit to staying at least two (2) feet above the groundwater table at ali times
during quarry excavation or until such time that AFSI can provide a written demonstration of
all permits or approvals as required by the Office of the State Engineer for exposure and/or use of groundwater.
PIease respond. '
12. It appears that the operator has no immediate plans and has provided no itemized costs for reclamation of the
slick, rock faces noted as West Highwall(a) and West Highwall(b) in the Division's April 8, 2002 inspection
report. The current configuration of each highwall is as follows: (a) 497' long x 176' high ~ 83 degrees, and (b)
497' long x 348' high @ 40 degrees. Although the operator reports that these highwalls aze stable, the
configurations noted above do not adequately meet the requirements of the existing (and proposed) reclamation
plans. Under the terms of the approved and proposed plans, the operator would need to construct a series of
