§ 211.133. Blast reports.

 (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 shall contain, at a minimum, the following:

   (1)  The locations of the blast and monitoring readings.

   (2)  The name of the blasting activity permittee.

   (3)  The blasting activity permit or appropriate mining permit number.

   (4)  The date and time of the blast.

   (5)  The printed name, signature and license number of the blaster-in-charge.

   (6)  The type of material blasted.

   (7)  A sketch showing the number of blast holes, burden, spacing, pattern dimensions and point of initiation.

   (8)  The diameter and depth of blast holes.

   (9)  The height or length of stemming and deck separation for each hole.

   (10)  The types of explosives used and arrangement in blast holes.

   (11)  The total weight in pounds of explosives and primer cartridges used.

   (12)  The maximum weight in pounds of explosives detonated per delay period of less than 8 milliseconds.

   (13)  The type of circuit, if electric detonation was used.

   (14)  The direction and distance in feet from the blast site to the nearest building not owned by the blasting activity permittee or its customer.

   (15)  A description of the nearest building location not owned or leased by the blasting activity permittee or its customer based upon local landmarks.

   (16)  The scaled distance.

   (17)  The weather conditions.

   (18)  The direction from which the wind was coming.

   (19)  The measures taken to control flyrock, including whether or not mats were used.

   (20)  The total quantity and type of detonators used and delays used.

   (21)  The number of individuals in the blasting crew.

   (22)  The maximum number of blast holes or portions of blast holes detonated per delay period less than 8 milliseconds.

   (23)  The monitoring records required by §  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 in subsection (b), are provided. Monitoring records shall be made part of the blast report within 7 days, if requested by the Department.

   (24)  If a misfire occurred, the actions taken to make the site safe as specified in §  211.157 (relating to postblast measures).

 (b)  The Department may require monthly summaries of these reports. The summaries shall include the date and time of the blasts, scaled distance, peak particle velocity, airblast, monitoring location, amount and types of explosives used and other information the Department deems necessary to ensure compliance with this chapter.
