[PL 1995, c. 700, §35 (NEW).]
2. Airblast. "Airblast" means an atmospheric compression wave resulting from the detonation of explosives, whether resulting from the motion of blasted materials or the expansion of gases from the explosion.
[PL 1995, c. 700, §35 (NEW).]
3. Blaster. "Blaster" means a person qualified to be in charge of or responsible for the loading and firing of a blast.

[PL 1995, c. 700, §35 (NEW).]
5. Blast site. "Blast site" means the area where explosive material is handled during the loading of drilled blastholes, including the perimeter formed by the loaded blastholes and 50 feet in all directions from loaded blastholes.
[PL 1995, c. 700, §35 (NEW).]
6. Detonating cord. "Detonating cord" means a flexible cord containing a center core of high explosives that may be used to initiate other explosives.

[PL 1995, c. 700, §35 (NEW).]
9. Matting. "Matting" means a covering placed over load holes and adjacent areas in order to minimize generation of flyrock and limit airblast effects.

11. Passenger car equivalents at peak hour. "Passenger car equivalents at peak hour" means the number of passenger cars, or, in the case of nonpassenger vehicles, the number of passenger cars that would be displaced by nonpassenger vehicles, that pass through an intersection or on a roadway under prevailing roadway and traffic conditions at that hour of the day during which traffic volume generated by the development is higher than the volume during any other hour of the day. For purposes of this article, one tractor-trailer combination is the equivalent of 2 passenger cars.
[PL 1995, c. 700, §35 (NEW).]
12. Peak particle velocity. "Peak particle velocity" means the maximum rate of ground movement measured by any of the 3 mutually perpendicular components of ground motion.

[PL 1995, c. 700, §35 (NEW).]
14. Private drinking water supply. "Private drinking water supply" means a surface water supply, a dug well, a spring or a hole drilled, driven or bored into the earth that is used to extract drinking water for human consumption and that is not part of a public drinking water supply.
[PL 1995, c. 700, §35 (NEW).]
15. Production blasting. "Production blasting" means blasting conducted for the purpose of extracting or removing natural materials for commercial sale or beneficiation.
[PL 1995, c. 700, §35 (NEW).]
16. Public drinking water source. "Public drinking water source" means a groundwater well or a surface water source that directly or indirectly serves a water distribution system that has at least 15 service connections or regularly services an average of at least 25 individuals daily at least 60 days of the year.
[PL 1995, c. 700, §35 (NEW).]

"Reclamation" does not include the filling in of pits and the filling or sealing of shafts and underground workings with solid materials unless necessary for the protection of groundwater or for reasons of safety.
[PL 2005, c. 158, §9 (AMD).]
