Prior to drilling of an oil or gas well, the operator shall establish a continuous seventy-two-hour ambient noise level at the nearest property line of a residence or public building, school, medical, emergency or other public residence or public facility, or 100 feet from the nearest residence or public building, school, medical, emergency or other public residence or public facility, whichever point is closer to the affected facility. In lieu of establishing the above seventy-two-hour ambient noise level, the operator may assume and use, for the purposes of compliance with this chapter, a default ambient noise level of 55 dBA. The sound level meter used in conducting any evaluation shall meet the American National Standard Institute's standard for sound meters or an instrument and the associated recording and analyzing equipment which will provide equivalent data.
