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.
'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.
'Monthly 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.

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:
