( 4.08 USE OF EXPLOSIVES
•\ 4.06.1 General Require
Colowyo will comply with all applicable State and Federal laws in the use
of explosives.
Colowyo will conduct all blasts that use more than five pounds of
explosives or blasting agent according to the schedule required by
Section 4.08.3.
All blasting operations at the Colowyo operation will be conducted by
experienced, certified, trained and competent persons who understand the
hazards involved. Each person responsible for blasting operations will
possess a valid certification in accordance with the appropriate federal
and state law.
4. 2 Pre-blasting Survey
Upon request to the Division by a resident or owner of a dwelling or
structure located within one-half mile of any part of the permit area,
Colowyo will promptly conduct a pre-blasting survey. A copy of
correspondence advising our neighbors of this opportunity is provided in
Exhibit 14 - Seismograph Measurements, Item 2. A report of the survey
will be submitted to the Division and to the person requesting the
survey. The pre-blasting survey will assess the condition of the
structure or dwelling and document any pre-blasting damage, including any
physical factors which might be reasonably affected by blasting. Such
a survey will determine only the surface condition of pipes, cables,
transmission lines, wells and other water systems; however, special
attention will be given to the pre-blasting conditions of wells and other
water systems used for human, animal or agricultural purposes and to the
quantity and quality of that water.
A written report of any pre-blasting survey will be prepared and signed
by the person conducting the survey. This report will include any
proposed adjustments to the blasting program which might be necessary to
be incorporated or should be incorporated to prevent damage. A copy of
the report will be provided to the person requesting the survey and to
the Division.
