(B) Blasting shall be limited to the period between 10:00 a.m. to 5:00 p.m. on weekdays, and explosives shall not be detonated on weekends or holidays recognized by the state, except when necessary to detonate a loaded shot which could not be detonated because of sudden adverse weather or other conditions which would not reasonably be foreseen by the quarry operator.
(C) All blasting shall be conducted by a qualified blaster pursuant to applicable requirements, if any, of the state and federal regulations.
(D) Blasting shall not occur during weather conditions that are known to cause a reflection of a significant amount of the noise and energy of the blast back to the ground unless a loaded charge must be detonated before the end of the day. Such weather conditions may include:
(1) A severe temperature inversion;
(2) Periods of strong winds; and
(3) Calm overcast days with very low cloud ceilings.
(E) Blasting shall come no closer than 100 feet to any natural gas pipelines unless the pipeline company authorizes or company authorizes or confirms, in writing, a lesser distance, provided that such distance shall, in no event, be less than 25 feet.
(F) Blast hole drillers shall report any cavities encountered during drilling to the blasting supervisor who shall record such reports in a blasting report. During loading explosives, all cavities shall be sleeved or stick explosives shall be used and the amount of explosives loaded into each hole monitored and recorded to avoid overloading a blast. These blasting reports shall be made available for inspection and copying to the town officials during normal business hours.
