Section 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 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).(b) The Department may require monthly summaries of these reports. The summaries must 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.The provisions of this §211.133 amended June 22, 2018, effective 6/23/2018, 48 Pa.B. 3711.The provisions of this §211.133 amended under sections 1917-A and 1920-A of The Administrative Code of 1929 (71 P.S. §§ 510-17 and 510-20); section 4.2 of the Surface Mining Conservation and Reclamation Act (52 P.S. § 1396.4b); section 11(e) of the Noncoal Surface Mining Conservation and Reclamation Act (52 P.S. § 3311(e)); sections 7 and 11 of the act of July 1, 1937 (P.L. 2681, No. 537) (73 P.S. §§ 157 and 161); sections 3 and 4 of the act of July 10, 1957 (P.L. 685, No. 362) (73 P.S. §§ 166 and 167); Reorganization Plan No. 8 of 1981 (71 P.S. § 751-35); section 2(f) of the act of May 18, 1937 (P.L. 654, No. 174) (43 P.S. § 25-2(f)); and Reorganization Plan No. 2 of 1975 (71 P.S. § 751-22).
