Z For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.
3 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, Section B, Table 1 to identify 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).
SWU-245, last revised 11/1/2018
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 me/L", where XX is the numerical value of the detection limit, reporting
limit, etc. in mg/L.
Note: !f you report a sample value in excess of the benchmark, you must implement Tier I, Tier 2, or Tier 3 responses. See General Permit text.
Part B: Vehicle Maintenance Area Monitoring Results: only for facilities averaging > 55 gal of new oil per month.
