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."

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, Section B, Table 1 to identify 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

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.

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.

Receiving Stream: Clark's Creek
Describe the industrial activities that occur within the outfall drainage area: Reel storage, machine
shop. and warehouse.
2. Color: Describe the color of the discharge using basic colors (red, brown, blue, etc.) and tint
(light, medium, dark) as descriptors: Color was grayish brown from gravel dust.
3. Odor: Describe any distinct odors that the discharge may have (i.e., smells strongly of oil,
weak chlorine odor, etc.): No odor was present.
4. Clarity: Choose the number which best describes the clarity of the discharge, where 1 is
clear and 5 is very cloudy:
1 Q2 3 4 5
S. 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:
01 2 3 4 5
6. Suspended Solids: Choose the number which best describes the amount of suspended
solids in the stormwater discharge, where 1 is no solids and 5 is extremely muddy:
1 2 03 4 5
7. Is there any foam in the stormwater discharge? Yes No
B. Is there an oil sheen in the stormwater discharge? Yes No
9. Is there evidence of erosion or deposition at the outfall? Yes No
10. Other Obvious Indicators of Stormwater Pollution: None
List and describe: Gravel dust generated by the adhacent rock quarry was visible in the run-off.
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.
