Ray Date of Inspection: 6-20-2021 Time of Inspection: 9:10 am/ 11:50am Total Event Precipitation (inches): .95" -According to WeatherUnderground; rain gauge broken/leaking All permits require qualitative monitoring to be performed during a "measurable storm event." A "measurable storm event" is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period, and the permittee obtains approval from the local DEMLR Regional Office.
