If a value is in excess of the benchmark, or outside the benchmark range (for pH), you must implement the Tier 1 or Tier 2 responses in the General Permit. Tier 2
Monthly sampling shall be done until 3 consecutive samples are below the benchmark or within the benchmark range.
' TSS benchmark values are 100 mg/I, except when discharging to ORW, HOW, Trout, and PNA waters where they are 50 mg/I.
For each sampled measurable storm event the total precipitation must be recorded using data from an on -site rain gauge.
