This bill regulates blasting operations conducted by quarries in Limestone County, specifically prohibiting such activities outside the corporate limits of any municipality within one and a half miles of any building or structure designated as a historical site, as defined in Section 40-8-1 of the Code of Alabama 1975. The new legal language inserted into the current law specifies these restrictions on blasting operations, ensuring the protection of historical buildings and sites in the area.

Additionally, the bill includes a provision stating that the restrictions outlined in subsection (a) do not apply to quarries that were already in existence on the effective date of the act. The bill is set to take effect immediately upon its passage.
