highwall at the time of reclamation. In particular, the geotechnical observations and measurements will include evaluation of
the presence or absence of clay filling in geologic structures that dip out of the quarry face, and will evaluate any changes in
orientation, spacing, and roughness of geologic structures observed relative to the observations documented in the initial
report.
2. The Applicant must commit to preparing a blasting report for each shot. These reports must be retained by the Operator for
at least three years and be available for inspection by the DRMS on demand. The reports shall contain the following data:
a) Location, date, and time of blast;
b) Name, signature, and license number of blaster -in- charge;
c) Identification, direction and distance, in feet, from the nearest blast hole to the nearest potentially affected structure
either:
i. not located in the permit area; or
ii. not owned nor leased by the person who conducts the mining operations;
d) Type of material blasted;
e) Sketches of the blast pattern including number of holes, burden, spacing, and delay pattern. Sketches shall also
show decking, if holes are decked to achieve different delay times within a hole;
f Diameter and depth of holes;
g) Types of explosives used;
h) Total weight of explosives used per hole and maximum weight of explosives used per 8- millisecond period;
i) Initiation system;
j) Type and length of stemming;
k) Mats or other protections used;
I) Type of delay detonator and delay periods used;
m) Number of persons in the blasting crew; and
n) Seismographic records, where required, including:
i. Type of instrument, sensitivity, and the calibration signal of the gain setting or certification of annual
calibration;
ii. Exact location of instrument and the date, time and its distance fs-om the blast;
iii. Name of the person and firm taking the reading;
iv. Name of the person and firm analyzing the seismographic record;
v. The vibration level recorded.

Recommendations:
1. The Division recommends the financial warranty liability be $113,900. The Operator should submit in
writing, a request for a Surety Reduction to the Division under separate cover. The request must include
an estimate of the actual cost to reclaim the site based on what it would cost an independent contractor
to complete reclamation. The Operator should include a copy of Task 003 enclosed in Attachment A to
meet this requirement. There is no fee for a Surety Reduction.
2. The Operator shall include the following information on the permit sign:
a. the name of the Operator,
b. a statement that a reclamation permit for the operation has been issued by the Colorado Mined
Land Reclamation Board; and.
c. the permit number.
3. The Operator should submit a Technical Revision (TR) to modify the reclamation seed mix to that
originally recommended by the NRCS (see table on Attachment C). There is a $216 fee for a TR.
