Current through Register Vol. 54, No. 28, July 13, 2024
(a) The
						blaster-in-charge shall prepare a report of each blast to provide the
						Department with sufficient information to reconstruct the conditions and events
						surrounding a blast. The Department may develop and require a blast report form
						to be used. The blasting activity permittee shall retain the blast report for
						at least 3 years and shall make the blast report available to the Department
						upon request. Blast reports must contain, at a minimum, all of the following:
(1) The location of at least one corner of
						the blast pattern expressed in latitude and longitude.
(2) The distance in feet and direction in
						degrees from the blast to the seismograph monitoring location.
(3) The latitude and longitude and a brief
						description of the monitoring locations. If monitoring is conducted at a home
						or other building with a 911 address, the address of the structure must be
						provided.
(4) The name of the
						blasting activity permittee and blasting contractor, if applicable.
(5) The blasting activity permit or
						appropriate mining permit number.
(6) The date and time of the blast.
(7) The printed name, signature and license
						number of the blaster-in-charge.
(8) The type of material blasted.
(9) A sketch showing the number of blast
						holes, burden, spacing, pattern dimensions, delay timing sequence, description
						of the conditions of the area immediately surrounding the blast site which
						includes identifying if the area is solid rock, a muck pile from a previous
						blast or an open face, and point of initiation.
(10) The diameter and depth of each blast
						hole.
(11) The height or length of
						stemming and deck separation for each hole.
(12) The amount of explosives loaded in each
						borehole.
(13) The types of
						explosives used and arrangement in blast holes.
(14) The total weight in pounds of
						explosives, product density for bulk blasting agents, weight of packaged
						blasting agents and primer cartridges used.
(15) The maximum weight in pounds of
						explosives detonated per delay period of less than 8 milliseconds.
(16) The type of circuit, if electric
						detonation was used.
(17) The
						direction in degrees and distance in feet from the blast site to the nearest
						building not owned or leased by the blasting activity permittee or its
						customer.
(18) A general
						description, including the street address and latitude and longitude, of the
						nearest building not owned or leased by the blasting activity permittee or its
						customer.
(19) The square root
						scaled distance to the nearest building or other structure neither owned nor
						leased by the blasting activity permittee or its customer except for demolition
						blasting operations where the cube root scaled distance must be used.
(20) The weather conditions.
(21) The direction from which the wind was
						coming.
(22) The measures taken to
						control flyrock, including whether or not mats were used.
(23) The total quantity and type of
						detonators used and delays used.
(24) The number of individuals in the
						blasting crew.
(25) The maximum
						number of blast holes or portions of blast holes detonated per delay period
						less than 8 milliseconds.
(26) A
						drill log showing the condition of all of the blast holes prior to loading and
						any other bore holes in the blast site.
(27) The monitoring records required under
						§
													211.173 (relating to monitoring
						records). Monitoring records shall be made part of the blast report within 30
						days of the blast. Beginning July 14, 2004, monitoring records shall be made
						part of the blast report within 14 days of the blast. The Department may grant
						a waiver to allow monitoring records to be made part of the blasting record
						within 30 days of the blast if all blasts, regardless of scaled distance, are
						monitored and monthly summaries of these reports, including the information
						required under subsection (b), are provided. Monitoring records shall be made
						part of the blast report within 7 days, if requested by the
						Department.
(28) If a misfire
						occurred, the actions taken to make the site safe as specified in §
													211.157 (relating to postblast
						measures).
