1 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.
3The 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.
'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."

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.

All permits require qualitative monitoring to be performed during a"meaPurlbleSE ferpent."
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:

(light,medium,dark)as descriptors:
3. Odor: Describe any distinct odors that the discharge may have(i.e., smells strongly of oil,weak
chlorine odor,etc.):
4. Clarity: Choose the number which best describes the clarity of the discharge,where 1 is clear
and 5 is very cloudy:
1 2 3 4 5
5. 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:
1 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 3 4 5
7. Is there any foam in the stormwater discharge? Q Yes Q No.
8. Is there an oil sheen in the stormwater discharge? ()Yes 0 No.
9. Is there evidence of erosion or deposition at the outfall? Yes o No.
10. Other Obvious Indicators of Stormwater Pollution:
List and describe
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.
