On June 19, 2007, the Division of Reclamation, Mining and Safety approved your 112c mining permit application. The
conditions to the approval are noted below:
1. During each year when development and/or production blasting occurs in the quarry, the
Operator shall include a geotechnical section into the annual reclamation report providing
updated geotechnical observations and measurements and associated recommendations for quarry
development to provide a safe highwall during operations and a long term stable 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;
