Noise
- Maximum airborne noise80 dBA
Airborne noise produced from extractive operations other than blasting must not exceed the 80 dBA maximum, continuous noise, as measured at the lot line of the extraction and mining use
- Maximum blast overpressure129 dB
The peak over pressure (noise) from any blast is limited to 129 dB, as measured at 5 or 6 Hz high pass system
- Maximum earth vibration peak particle velocity0.03 in/sec
Earth vibration produced from sources other than blasting must not exceed a maximum resultant peak particle velocity of 0.03 inches per second
