2. (2) The location, date and time of blast.
3. (3) The name, signature and license number of blaster-in-charge.
4. (4) The identification of and the direction and distance, in feet, to the nearest dwelling, public building, school, church, commercial or institutional building or other structure.
5. (5) Weather conditions, including temperatures, wind direction and approximate velocity.
6. (6) The type of material blasted.
7. (7) The number of holes, burden and spacing.
8. (8) The diameter and depth of holes.
9. (9) The types of explosives used.
10. (10) The total weight of explosives used.
11. (11) The maximum weight of explosives detonated per delay interval.
12. (12) The maximum number of holes detonated per delay interval.
13. (13) The initiation system.
14. (14) The type and length of stemming.
15. (15) The mats or other protections used.
16. (16) The type of delay detonator and delay periods used.
17. (17) A sketch of the blast pattern, including number of holes, burden, spacing, decks and delay pattern.
18. (18) The number of persons in the blasting crew.

19. (19) Seismographic and airblast records, when required, including the type of instrument, sensitivity and calibration signal of the gain setting or certification of annual calibration and the following:

    1. (i) The seismographic or airblast level, or both, reading, including the exact location of seismograph and its distance from the blast.
    2. (ii) The name of the person taking the seismograph reading.
    3. (iii) The name of person and firm analyzing the seismographic record.
20. (20) The reasons and conditions for each unscheduled blast.

Notes of Decisions

A coal mining operator charged with a violation of the air blast calibration requirements could challenge the violation and the amount of the fine in one appeal proceeding even though the fine was issued after the expiration of the appeal period for challenging the compliance order and the company did not timely appeal the compliance order.
