1 Monthly sampling (instead of quarterly) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
'The total precipitation must be recorded using data from an on-site rain gauge. Unattended sites may be eligible for a waiver of the rain gauge requirement.
3 For sampling periods with no discharge, you must still submit this discharge monitoring report with a checkmark here.
4The TSS benchmark value is 100 mg/L; except when discharging to ORW, HOW,Trout, and PNA waters in which case the benchmark is 50 mg/L.

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.
By this signature,I certify that this report is accurate and complete to the best of my knowledge:
