'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. 'See General Permit Table 1, identifying the especially sensitive receiving waters classifications where the more protective benchmark applies. 'For 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. 4Monthly sampling (instead of semi-annual) must begin with the second consecutive benchmark exceedance for the same parameter at the same outfall. sTotal 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. 'For sampling periods with no discharge at any single outfall, you must still submit this discharge monitoring report with a checkmark here.

The solvent management plan shall include a list of the total toxic organic compounds used along with other requirements 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 elan included in the Stormwater Pollution Prevention Plan." 5' glzz Ste.2z 19 Na a (Print name) Title (Print itle C�� ZZ2K Signature Mail Original to: Division of Water Quality Attn: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Date "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the Information submitted.
