Note: If you report a sampled value in excess of the benchmark value, or outside the benchmark range for pH, you must implement Tier 1 or Tier 2 responses in the General
Permit.
1See If pH values outside this range are recorded in sampled stormwater discharges, but ambient precipitation pH levels are lower, then the lower threshold of this benchmark
range is the pH of the precipitation (within instrument accuracy)instead of 6 S.U. Readings from an on -site or local rain gauge (or local precipitation data) must be documented
to demonstrate background concentrations were below the benchmark pH range of 6-9.
2See General Permit text to identify whether the more protective benchmark applies for especially sensitive receiving waters.
3For purposes of this permit the definition of Total Toxic Organics is that list as stated in Appendix D, Table II of Chapter 40 Code of Federal Regulations (CFR) Part 122.

STORMWATER DISCHARGE OUTFALL (SDO)
MONITORING REPORT
Facilities that incorporate a solvent management plan into the Stormwater Pollution Prevention Plan may request that DWQ waive monitoring of total toxic organics. 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 allowed such a waiver, the
discharger shall sign the following certification statement:
Solvent Management Plan 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 all the provisions of the solvent
management plan included in the Stormwater Pollution Prevention Plan."
