Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceed ance forth e same parameter at the same outf all.
r For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.

'Total Toxic Organics sampling is applicable only for those facilities which perform meta If inishingoperations, 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 forthe facility subjectto the requirementto 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 forcathode 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 forTTO monitoring
maybe 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 theTTOmonitoringwaiver,thedischargershallsignthefollowingcertificationstatement:
"Based upon my inquiry of the person or persons directly responsible for managing compliance with the permit monitoring requirementfor total toxic organics
(TTO), I certifythat to the best of my knowledge and belief, no dumping of concentrated toxic organics into the stormwater o r areas which are exposed to rainfall or
stormwater runoff has occurred since filing the last discharge monitoring report. I further certifythat this facility is im plementing 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, orother similar non -numerical
format. When results are below the applicable limits, they must be reported inthe format, "<XXmg/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 I, rer2, or tier 3 responses. See General Permit text.
