Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall.
2 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.
4 See General Permit, Table 3 identifying the especially sensitive receiving water classifications where the more protective benchmark applies.
s Total Toxic Organics sampling is applicable only for those facilities which perform metal finishing operations, manufacture semiconductors, manufacture
electronic crystals, or manufacture cathode ray tubes. For purposes of this permit the definition of Total Toxic Organics is that definition contained in the EPA
Effluent Guidelines for the facility subject to the requirement to sample (for metal finishing use the definition as found in 40 CFR 433.11; for semiconductor
manufacture use the definition as found in 40 CFR 469.12; for electronic crystal manufacture use the definition as found in 40 CFR 469.22; and for cathode ray
tube manufacture use the definition found in 40 CFR 469.31).

Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may so certify, and the requirement for TTO monitoring
may be waived. The solvent management plan shall include a list of the total toxic organic compounds used and the other elements listed in the General
Permit. For those facilities electing to employ the TTO monitoring waiver, the discharger shall sign the following certification statement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirement for total toxic organics
(TTO), 1 certify that to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater or areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certify that this facility is implementing the all the provisions of the
solvent management plan included in the Stormwater Pollution Prevention Plan."

Note: Results must be reported in numerical format. 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 mg/L", where XX is the numerical value of the detection
limit, reporting limit, etc. in mg/L.
Note: If you report a sample value in excess of the benchmark, you must implement Tier 1, Tier 2, or Tier 3 responses. See General Permit text.

Please verify whether Qualitative Monitoring must he performed during a "representative storm

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event" However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
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 DWQ Regional Office.
