Blasting Permits
BLASTING REGULATIONS
The City of Huntsville’s blasting regulations were enacted in 1989 and are derived from studies conducted by the U.S. Bureau of Mines of structural response to blasting activities near quarries. Based on the U.S. Bureau of Mines studies, the ground vibration and air over-pressure limits outlined in the ordinance fall below the thresholds that would result in structural damage from blasting.
The State of Alabama passed the “Alabama Explosives Safety Act of 1993,” which regulates any municipality that does not have a blasting ordinance in place prior to its inception. The regulations outlined in this Act are less stringent than the COH ordinance limits.
BLAST MONITORING
Every blast must be conducted under the supervision of an Alabama-certified blaster and during daylight hours (no earlier than 7 a.m. CST). Blasting companies must be permitted, licensed and insured.
Every blast must be monitored using a calibrated seismograph that must be located outside or off of the property under the control of the area where the blast is taking place. Seismographs are required to be calibrated annually by a certified laboratory.
Blast notifications are required to be given to the City of Huntsville’s Natural Resources Department four (4) hours prior to the planned blast. A 24-hour notice is required for weekend blasts.
The Department of Natural Resources and Environmental Management has four (4) seismographs used to determine compliance and are available for installation at any residence located inside the city limits of Huntsville. These seismographs are calibrated annually and are installed on a first-come, first-served basis. If you would like to monitor your residence, please contact 256-427-5750 for availability.
BLAST ENFORCEMENT
Blasting Permits are issued by the City’s Department of Natural Resources prior to initiation of blasting activities.
Ground vibrations and airblast standards are enforced by the City by reviewing site monitoring reports, performance of inspections and conducting seismographic monitoring.
