' 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.
5 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), I 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."

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event"or"measureable storm event"(requirements vary,depending on the permit).
I 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.

Thermo Scientific pH Meter Operation and Calibration Operation and Calibration
Calibration
1. Prepare buffers that bracket the expected sample pH(pH 7.0,4.0,10.0)
2. Turn the meter on,and wait for the display to stabilize.
3. Press the"Calibration"button.
4. Rinse the electrode with DI water,shake off excess water,blot dry and then place into first buffer solution(7.0).
5. After the meter has stabilized and the result has been displayed,record the result and then press the"Calibration"button.
6. Rinse the electrode with DI water,then gently shake off excess water and blot dry.Place electrode into second buffer solution(4.0).
7. After the meter has stabilized and the result has been displayed,record the result and then press the"Calibration"button.
8. Rinse the electrode with DI water,then gently shake off excess water and blot dry.Place electrode into second buffer solution(10.0).
9. After the meter has stabilized and the result has been displayed,record the result and then press the"Calibration"button.
10. Press the"Measure"key,and record the slope.The slope should always be between 92-102%.If not,repeat the calibration.If the slope is still outside the range,contact the EHS
Specialist.
11. The meter is now in measurement mode,and samples can be analyzed.
pH Measurement
1. If power is off,press the power key.
2. Press the"Measure"key.
3. Rinse the electrode with DI water,gently shake off excess water and blot dry.
4. Place electrode into sample,gently stir and then allow meter to stabilize and display results.
5. Repeat as needed.
NOTES:
When not taking measurements,the pH electrode should be kept in the storage solution,not in DI water or buffer solution.
When ready to take measurements,rinse the electrode with DI water,and then gently shake of the excess water and blot the electrode with a clean,dry tissue.DO NOT RUB the electrode
as this may cause static build up.Then place the electrode into the sample or pH buffer for calibration.
When placing the electrode into a sample or buffer solution,gently stir with the electrode for a few seconds,and then wait for the meter to stabilize and for the display to stop flashing and
to display the result.
Fresh buffer solution must be used each day.Throw out old buffer solution.
