§ 150.20  VIBRATION AND AIR BLAST LIMITS.
   (A)   Any one of the frequency response method of recording ground vibrations, the U.S. Bureau of Mines Siskind Curve Method or the OSMRE alternative blasting level criteria shall be used for analyzing the seismograph results.
   (B)   The maximum peak particle velocity (PPV), measured in the 40 hertz frequency range shall be sixty-hundredths per second.
   (C)   The maximum air blast at any seismograph monitoring location, measured in the “A” scale, shall be 125 decibels, and if measured in the lienal scale, shall be 129 decibels (provided that the equipment can measure the energy down to six hertz).
