' Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
' For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
'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.
"See General Permit text, Table 1, identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
Note: Results must be reported in numerical format. For example, do not report Below Detection Limit, BDL, <PQL, Non -detect, ND, or other similar non -
numerical format. When results are below the applicable limits, they must be reported in the format. "<XX m¢/L", where XX is the numerical value of the
detection limit, reporting limit, etc. in mg/L. Conversely, where fecal coliform results exceed the dilution upper limit, report the result as ">XX"

Total Event Precipitation (inches):
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
Office.
