Section 460:25-13-18 - Blasting requirements

(a) All blasting shall be conducted between sunrise and sunset.

(1) The Department may specify more restrictive time periods, based upon public requests or other relevant information, according to the need to adequately protect the public from adverse noise.

(2) Blasting may, however, be conducted between sunset and sunrise if:

(A) A blast that has been prepared during the afternoon must be delayed due to the occurrence of an unavoidable hazardous condition and cannot be delayed until the next day because of a potential safety hazard.

(B) A complete written report of blasting at night is filed by the operator with the Department not later than three days after the night blasting. The report shall include the reasons for the delay in blasting, including why the blast could not be held over to the next day, when the blast was actually conducted, the warning signals given, and a copy of the blast report.

(b) Access to the area shall be controlled to prevent the presence of livestock or unauthorized personnel during blasting and until an authorized representative of the operator has reasonably determined:

(2) That access to and travel in or through the area can safely be resumed.

(c) Flyrock shall not be cast from the blast area.

(d) In all blasting operations, except as otherwise authorized in this Section, the maximum safe peak particle velocity shall not exceed the requirements of Section 460: 25-13-19(a) at the location of any dwelling, public building, school, church, or commercial or institutional building.
