4. Rule 6.4.3(c) requires that Exhibit C include one or more maps to legibly portray the existing
topography of the area with contour lines of sufficient detail to portray the direction and rate of slope
of the affected land. Please submit a new or revised map depicting the topography.
5. County Road 2 and the boundary fences appear to be within 200 feet of the affected boundaries
shown on Exhibit C, but were not described as structures as required by Rule 6.4.3(g). Please
provide the names and addresses for the owners of all structures within 200 feet of the affected
lands, and assure the Division that notice of the application was provided to these owners of
structures. Please be aware that Rule1.1(48) defines "Structure, Significant, Valuable and
Permanent Man-made" to include, but not be limited to, "buildings, houses, barns, fences, above or
below ground utilities, irrigation ditches, maintained or public roads, bridges, railroad tracks,
cemeteries, communication antennas, pipelines, water welts, water storage structures, discharge and
conveyance structures, etc."
Rule 6.4.4 Exhibit D -Mining Plan
6. Per Rule 6.4.4(c), please describe all water diversions and impoundments sufficiently to bond for
their removal. Please describe the handling of any wastewater generated on the site (e.g., scrubber
blow down water, concrete truck wash water). Please also describe any storm water run-off controls
that may be implemented.
7. To assist in the calculation of the financial warranty and as required by Rule 6.4.4(d), please indicate
the size of areas to be worked at any one time. Please indicate the maximum area of disturbance,
linear feet of any highwall, the grade of pit side slopes to be maintained during mining, and maximum
size of area to be topsoiled. Please relate the approximate timetable requested by Rule 6.4.4(e) to
the extent of mining disturbance and the process of reclamation.
8. The application states that Grand Gravel expects contractors to install an asphalt plant and concrete
batch plant on site. To ensure the adequacy of the calculated bond, the Division needs the applicant
to describe what controls will be implemented to ensure materials associated with asphalt production
and distribution do not adversely impact the environment.
• Please locate the structures and associated environmental controls on the Mining Plan map.
• Please list any chemicals and/or hazardous waste, such as asphalt cement and diesel fuel, that
will be used on site in association with these plants, the volumes of each, their storage locations,
and how they will be stored.
• Please describe how the facilities will be managed to ensure groundwater and surface water will
not be impacted. Please describe what controls will be implemented to ensure materials
associated with asphalt production and distribution (such as oil unloading and storage facilities)
do not adversely impact the environment. What actions will be taken the event of a leak or spill?
9. What is the maximum amount of waste asphalt that will be stored on site at any one time? Please
locate the stockpile on the Mining Plan map. What environmental controls will be used in waste
asphalt storage and/or disposal?
10. What does it mean that the "portable mobile concrete batch plant will have own water source?"
Please describe the potential source(s) of the water, keeping in mind that all water used in the
operation must be decreed and/or permitted for such use.
11. Regarding water to be used by the operation (e.g., dust control, in the batch plants), it is my
understanding, from discussions with Mr. Richard Curry during the June 27, 2005, inspection, that all
water used in the operation is diverted from the river and stored during "free river" (no call)
