Date of Inspection: Time of Inspection: 5:40 AM Z02O OWR -RAL FILES Total Event Precipitation (inches): 0.4 SECrIpN 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.

Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil, weak chlorine odor, etc.): none 4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is clear and 5 is very cloudy: Qualitative Analysis =1 (1 2 3 4 5) 5. Floating Solids: Choose the number which best describes the amount of floating solids in the stormwater discharge, where 1 is no solids and 5 is the surface covered with floating solids: Qualitative Analysis = i 1 2 3 4 5 b.

Other Obvious Indicators of Stormwater Pollution: List and describe None. Note: Low clarity, high solids, and/or the presence of foam, oil sheen, or erosion/deposition may be indicative of pollutant exposure. These conditions warrant further investigation.
