I believe they are required to maintain records of those events and the locations where they occurred. Then they can identify the NMS results to confirm the decibel level of each event. This is important because the Growth Management Act (GM A) contains environmental noise limits contained in WAC 173-60-040, maximum permissible environmental noise levels during 10 pm-7 am period and not to exceed 1.5-15 minutes in any one-hour period of the day) governed by DOE.
